The Different Smart Home Technologies

The Different Smart Home Technologies In this report I am going to explain the different smart home technologies EIB also known as KNX and CBUS. I will be giving a full explanation about what each system is capable of and a little about their company background. I will also be comparing both system with the advantages and disadvantages for each system. (Add more) EIB (KNX) System EIB (KNX) is the only worldwide bus system which offers a complete range of transmission media for building control systems, including Twisted Pair, Power line, Radio Frequency (RF), infrared (IR), Coaxial cable and Ethernet IP. This smart home network is designed to work independently on any particular hardware platform. It can be controlled through a network of 8 bit micro controller to a PC. EIB (European Installation Bus) uses the twisted pair functioning which uses a cable with two pairs, using only one pair from the twisted cable for communication. The line voltage for these cables is 36v DC. Each device has a bus coupling unit which is used to connect sensors and actuators to the bus for example a NIC card on a PC. EIB is a field bus technology which is maintained by the Konnex Association. Its topology is the same as the CBUS system. EIB (KNX) has over 176 members and manufacturers in 29 different countries some of which include Ardan smart home, ABB, Armour Home Electronics Ltd, Bosch, Basalte BVBA, CIAT, and many other companies based around the world. You can find the full list of members and manufacturers at: http://www.knx.org/ A field bus is a special form of Local Area Network that implements, not computers but sensors and actuators at its nodes and is optimised for short point to point communication of status and command messages (M C-Wonders). The field bus system is built up in 7 OSI layers (as shown below) which is also known as the protocol stack. However the EIB system does not use all 7 layers it only uses 5 layers (See diagram below) this shows the difference between an OSI Model and the EIB Model. OSI Protocol Stack EIB Protocol Stack Layer 1 The physical layer in the EIB protocol stack defines both the bit by bit transmission of data and the physical media type (how the bits are transmitted depends on the media type) Here is a specification of the twisted pair which is used in the EIB system: RS485 bit communications Twisted pair cable 9.6 kbps 1000m range 64 end devices per line Layer 2 The data link layer defines the device addressing mechanism, making sure each device has its own unique address. It also defines the method of access to the bus arbitration as there must be a control mechanism which has to stop devices from communicating on the bus at the same time. The device address is as follows: Device number: 0 63 Line number: 0 11 Zone number: 0 14 An EIB twisted pair system can only have 15 zones, 12 lines per zone and 64 devices per line. Layer 3 On the Network layer there can only be device to device communications as this allows data packet transmission between devices and connectionless communications. This layer also uses Unicast and Group addressing. Unicast addressing is only used during device installation (system access mode) also using the physical device address. Group address is equivalent of multicast and broadcast addressing as it has normal bus operation mode and allows an input device to control many other grouped output devices. The group address consists of a main group, middle group and a sub group e.g. 2.4.2 Layer 4 The transport layer is responsible for reliable communications as it creates a connection between both the sender and the receiver using positive acknowledgment with retransmission (PAR). The PAR sequence is as follows: A connection between sender and receiver is set up Sender sends data with sequence number Sender waits a set period of time for an Acknowledgment from receiver. If none data is sent again. After 3 attempts to send the data have failed the operation will terminate its connection If the receiver suspects an error at any point it will send and (Nack), which terminates the connection. 2. When all telegrams have been transmitted the connection is terminated. Layer 7 This is the application layer in the EIB protocol. This layer is based around the concept of communication objects. Each device on the networks paired with a software application which has the relevant functions it needs. The application associates objects to particular devices as these objects are the communication methods for EIB which use the group address within the device. Each application on each device stores an association table, this association table links to the group address table and a communication object table for example: Sensor device 1.1.1 sends 1/1/1 to actuators 1.1.2 and 1.1.3 to turn on the actuators (1.1.2 and 1.1.3) Sensor device 1.1.1 sends 1/1/2 to actuators to turn them off Here are some of the advantages of the EIB system with some explanation: It has international standard making it future proof ISO/IEC CENELEC CEN SAC AN SI/A SHRAE With product certification, KNX guarantees interoperability and interworking of products EIB makes sure that each different manufacturer, product and application communicates with each other. Ensuring a high quality of flexibility. High product quality EIB makes sure each manufacturer follows the correct compliances in order gain a KNX Certification. Unique Manufacturer independent Engineering Tool Software (ETS) ETS allows planning, engineering and configuration for all certified products. It is manufacturer independent allowing the system to combine different manufacturers to one installation Can be used with all applications in home and building control EIB can be used for all functions and applications in a home or building control varying from lighting and shutter control to security, ventilation control. Fit for use in different buildings EIB can be easily installed into new or even existing buildings, making it easily extendable making sure it adapts to new needs. Supports different configuration modes E-Mode Easy installation mode S-Mode System installation mode Supports several communication media Twisted pair Power line Radio frequency Ethernet IP Can be coupled to other systems The EIB system can be mapped to BACnet objects or offers a possibility to interface within the DALI technology. Independent form any hard- software technology EIB can be understood on any microprocessor platform and can be implemented from start but only for easy market entrance. It cal also take recourses to providers of the systems components. An EIB system is able to do many things at the touch of one button some examples are shown below: Lighting EIB can store and recall different light moods and scenes by pressing the switch/dim button which controls lights on a central level. Being able to adjust internal lighting according to external brightness levels allows substantial energy savings. Shutters and blinds With automated sun protection, weather protection and time controlled shutters/blinds at the press of a button these can be opened or closed. Weather station This protects the blinds and shutters from destruction by wind, rain or frost, giving automated roof windows closing when raining. It also display wind speed, rain and also temperature and brightness levels. An EIB system can do many things at the touch of a button including heating, ventilation/ climate control, security, overriding functions, communications, and incorporation of audio-visual equipment and also helps in customer service. The twisted pair on the EIB, its bit level collision detection with overriding logical 0 which ensures that in case of a collision, the transmission always succeeds for the communication partners. Some of the disadvantages of the EIB (KNX) system are: can only be controlled through an 8 bit micro controller to a PC only allows up to 64 devices per line can only be device to device communication does not allow loop topologies CBUS System Clipsal BUS (CBUS) is a microprocessor control and management system for homes and buildings. This system is used to control electrical services such as lighting, audio visual devices, motors, etc. Either a simple on/off control for lighting or variable (analogue) type control for example dimmers. CBUS is easily controlled through virtually any type of electrical load. CBUS certifies each of its products has its own built-in microprocessor for reliability and fast operation allowing each unit to be programmed individually. CBUS uses a unique method of updating each unit which involves a method which can not involve a central computer or controller. Each unit device is assigned a specific time frame in which it broadcasts its status which is then synchronised by a self generated system clock pulse. This allows great quantities of data to be passed on in small time frames in low overheads and bandwidth requirements. CBUS is an interconnected system of inputs (sensors) and outputs (controllers) used to allow automatic operation and control of machinery or processes such as environments that can make and execute decisions with or without human interface (MC-Wonders). CBUS uses a UTP cat 5 cable which allows each of its devices to interconnect within the system. The maximum total cable length per network cannot exceed more than 1000 meters with a system voltage of 15v D.C 36v D.C (across any node in a network). Its data rate is 3500 bits/second with 64 byte frames. Its bus contention method uses CSMA/CD with CA. CBUS transmit units and dimmers units connect to the main power supply and other switches/sensors which are used to control a buildings electrical service. The network is electrically isolated from the mains supply operating at a safe extra low voltage level of 36v DC. The CBUS system is develops continuously therefore making it practically unlimited. Networks of 100 units are larger installations which have been divided allowing the system to be managed in sections, up to 1000 meters of cables may be in installed in each network. The CBUS system can be as large or as small as a user prefers it to be and it does not only simplify the design of automations needed but limits potential faults which makes trouble shooting easier. CBUS responds too many of the following devices: Home entertainment audio visual, lighting control Security integrated security, lighting Comfort scene setting, dimming Convenience central point control from touch screens, automated time based control, multiple point control, automated messages CBUS is suitable for many different applications for example: Residential Automation Home entertainment audio visual, lighting control Security integrated security, lighting Comfort scene setting, dimming Convenience central point control from touch screens, automated time based control, multiple point control, automated messages Standalone room lighting control Via a touch screen user interface becomes automated for conference rooms and home theatres Many different scene and mood setting are available Commercial light control In a warehouse high bay control is used for energy saving costs Energy saving costs in high rise buildings is brought to minimum by using fluorescent lighting. For retails and restraints mood lighting is used to set a scene Flexible control of lighting and audio visual used in boardrooms For hotel foyers, ballrooms, etc architectural lighting control is used CBUS supports all multi room audio visuals with a full range of amplifiers and ceiling speakers which are all controlled by switches and touch screens. As all electrics have to return to one central panel it is very expensive to convert existing houses to use CBUS unless renovations are being made allowing reconfiguration. A switch which is placed in the boardroom is programmed with the CBUS group address. When the light switch is pressed an on command is sent to the group address of the CBUS. The command which was sent to the group address from the input switch is then sent on to the CBUS network or all units throughout the network. Only the programmed units respond to the command form the group address. Other units which have not been programmed to respond the message will ignore the command as it was not intended for them. This is only an overview of the flexibility and power of the CBUS system. When using a CBUS system each device has to have a CBUS connection including devices such as the mains power will obviously need connection to the mains. Wiring for the mains and CBUS do not need to be adjoining as the mains can be connected to a different phase or completely different system. Field bus system The advantages of a system include: Less complex installation: this means less hassle with wiring as it can be done through a bus that carries the messages Total ownership cost becomes less: reduced cabling and installation time, easy modification and upgrade and easy to fault find means reduced costs. Offers more flexibility: Each node is a micro controller which is programmable. Each node has its own intelligence making no 1 point of failure. CBUS can have a maximum of 255 sub networks, within each sub network there is a combination of input and output units a sub network allows a maximum of 100 units which can connect to a single sub network. When sub networks contain units it is essential to be able to give each unit a address, there are 4 main levels of addressing which are available for these units these are: 1. Network address This is assigned to each sub network with a 2 digit HEX value 2. Unit address This unit address identifies the individual unit for example light switch 3. Area address Allows division of a sub network, it also enable messages to be sent to areas by the units 4. Group address Really a less specific area addressing scheme, only allows maximum of 255 groups on a sub network. There are two main devices which are needed in order to set up a CBUS system. These are a power supply and a PC interface which is used for programming the units. Some of the advantages of CBUS system are: CBUS can forcefully and reliably control all the different systems with low costs per node. There are many different tools which are used to allow 3rd party companies to interface with both PC and embedded systems. One CBUS connection controls a unlimited number of devices CBUS is very flexible for switching and controlling, for example functions may be removed, changed, added or reprogrammed at any time without bulky hard-wiring through the network itself. Simple installation process CBUS is able to control all different types of load including load, digital and analogue. Some of the disadvantages of the CBUS system are: it can have only one distribution panel does not allow loop topologies each device has to return to one central panel each device has to have a CBUS connection CBUS and EIB Compared CBUS and EIB systems are used to control electrical devices in home and building environments for example both home systems can control lighting, dimmers, audio visuals and many other electrics. They also have the same topologies available which includes the bus topology, star topology and the hybrid topology. Neither of these systems can form loop topologies as this does not allow the system to have a valid distribution panel. The EIB system can only uses device to device communications as this allows data packet transmission between devices making connectionless communication whereas the CBUS system uses a network connection which is set up on each node through each sub network mask. This also means that the CBUS system can have as many devices linked to one distribution panel making it an unlimited as an EIB system can only have up to 64 devices on each line within each zone available. Each CBUS product has its own built-in microprocessor which allows each unit to be programmed individually. As each unit device is assigned a specific time frame great quantities of data can be passed in small frames. In an EIB system there can only be device to device communication as this allows data packet transmission between devices and connectionless communications, within the transport layer is creates a connection between both sender and receiver. Both EIB and CBUS systems have a maximum cable length per network which cannot exceed more than 1000 meters with system voltage of 15v DC 36v DC. CBUS has a maximum of 255 sub networks within which there is a combination of input and output units. Within sub network a maximum of 100 units can be connected to a single network. In an EIB system the twisted pair system can only have 15 zones within those zones there can only be a maximum of 12 lines. There can only be a maximum of 64 devices per line on a zone meaning there is limited space on the system. A typical scene situation: There are two lighting strips within an office. Lighting strip 1 is located by the window, lighting strip 2 by the wall. These lights can be switched on and off manually. If there is sufficient ambient light, the lighting strips are switched off and are locked (i.e., they cannot be switched back on again) automatic switching on again when darkness falls is not required but is manually possible. Before the start of a working day a timer automatically switches lighting strip 2 on to guarantee sufficient light level. This is the layout of the office with strip lights and touch switches and actuators A solution to this problem would be to get bus devices including 1 touch sensor to fold, 1 bus coupling module which will have a brightness sensor and timer (1 channel) which is din rail mounted, 1 controller again it should be din rail mounted, 1switchin actuator 2 fold and a din rail mounted devices installed in the distribution panel When an outside has sufficient light, the brightness sensor will automatically switch off lighting and lock it. In order for this operation to succeed the brightness sensor telegram (address 1/0/3) is AND (gate) linked with the touch sensor telegram (address 1/0/1). The output of the AND gate sends a message (address 1/0/6) to the switching actuator (1.1.4) which will switch lighting strip 1. To avoid the brightness automatically switching the light back on when it is darker the result of the linking (1/0/6), this is why when the sensor is switched off both inputs in the AND gate are set to 0. These are the parameter blocks which are used in the programming of the system: PRICE COMPARISON

Essay for kirklands class Essay

I believe that the state should not by itself have the power to declare war on another nation or country without the consent of the national government. the reason behind why I think this is because I believe that the government itself has enough power to keep the branches and there paper works in order and to do what is needed and expected of them to do nothing easel over that or under. I also believe that we south Carolinians if we do not like what north Korea is doing we should just stay out of it unless north Korea brings us into it and the reason I think this is because, us south Carolinians declaring war on north Korea just because we don’t like what they are doing is pretty stupid to me. I believe we are smart enough to figure it out without declaring war on a country or a nation. If south Carolina is having problems maintaining their drinking water supplies, and if the government has attempted numerous times to correct the problem, but has repeatedly failed, I believe that the government should problem get help form a nether government or help from whoever can fix this problem because we need water and without water we will die. I believe that the national government should beagle to take action because it is a life or death situation so yes I think that the government of South Carolina also known as the local government should be able to get help from the national government and take the measures needed to fix this problem. I believe that the local government should try to figure it out before getting help from the national government, and if the national government can’t fix it then I think that the national government should beagle to ask another government for help to fix this life or death situation. But if they need to shut down the factory then they should do it because if the south Carolinians don’t have any water they could die and they need water because water was made to keep us alive just like food was made to keep us alive without water you can’t take a shower either and so everyone would stink. If the local chemical factory is causing this problem then they need to shut the chemical  factory down and move it to a different area so it can’t cause anymore problems to our water systems and we would need to move it to a place where it can’t contaminate anything that could herm us or bother us like were its not close to a farm food supplies or water supplies.

African Rock Python Essay

The African rock python. It is Domain: Eukarya. Domain is the highest taxonomic rank of organisms, higher than a kingdom. The African rock python falls under Eukarya because it is a multicellular organism composed of eukaryotic cells. It is Kingdom: Anamalia. Kingdom is the second highest rank. It falls under Anamalia for obvious reasons. It is Phylum: Chordata. Phylum is the primary division of the plant or animal kingdom. It is Class: Reptilia. Class is a group of related plants or animals, in the general classification of plants and animals. The African rock python falls under Reptilia because it has a characteristic of being cold-blooded. It is Order: Squamata. Order is a taxonomic rank used in classifying organisms, generally below the class, and comprised of families sharing a set of similar nature or characteristics. The African rock python shed their skin periodically and have very flexible jaws, which are characteristics of Squamata. It is Family: Pythonidae. Organisms belonging to the same family would have evolved from the same ancestors and share relatively common characteristics. The Pythonidae family is a family of non-venomous snakes who are powerful constrictors that wrap around their prey to kill it. This family includes the African rock python. It’s Genus: Python. In binomial nomenclature, the genus is used as the first word of a scientific name. It’s Species: Python sebae. Species is the second part of the name is the binomial nomenclature. The name Python Sebae was derived from the Greek mythology, which refers to a huge serpent. The largest snake in Africa and the third largest snake in the world, the African rock python, have long bulky bodies. Snakes are considered vertebrates because they have a backbone, a closed circulatory system, where the heart and blood vessels are continuously contracting. The blood never leaves the blood vessels. The outer layer of the epidermis is thick and lacks glands. It is characterized by keratin scales. Ranging anywhere from an average size of 18 to 20 feet long, but can grow up to 28 feet long! The females are larger than the males and can weigh almost 300lbs. However the size may vary according to their natural habitat. It is amazing to note that in areas where there is a higher population, the size of the African rock python has been smaller in size, as compared to areas where human habitat is less; the African Rock Python snake is much bigger in ize. African Rock Pythons are often tan with brown spots that have black outlines. This helps them camouflage in the environment, and gives them an advantage to hunt their prey or hide from potential predators. This is considered cryptic camouflage. A V-shape noticeably marks the face. This python is non-venomous, and has teeth curved inward to help pull in prey when eating. Like all pythons, the scales of the African rock python are small and smooth, and those nearby the lips control heat-sensitive pits, which are used to distinguish warm-blooded prey, even in the dark. Pythons also possess two functioning lungs, unlike more â€Å"advanced† snakes which have only one, and also have small, visible pelvic spurs, believed to be the remnants of hind limbs. It is said that snakes are evolved from lizards that burrowed in tunnels or in water, and the use of hind legs made it harder for them to burrow. Over time there legs started to grow shorter and eventually becoming useless, leaving behind what is now known as there spurs, located right before the anus. The rate of this evolution occurred at a slow constant pace over millions of years. This evidence of evolution would be considered phylogeny, the evolutionary relationship among species. African rock pythons reside in sub-Saharan Africa, but prefer evergreen forests or moist, open savannahs. You will always most likely find an African rock python associated with water and often are found near rivers and lakes. The African rock python has recently been found on the loose in Florida. Not many know how the massive snake happened to come about in Florida. Many believe they were released purposely, because the owner or breeder was ill-equipped for the intensity of this particular snake. A frightening factor has arisen since the African rock python has inhabited the south Florida territory. The Burmese python has already established foothold in the Everglades. The fear of a new â€Å"Super Snake† breed arising if the Burmese and African rock python were to mate, strikes fear that a hybrid python may be on the rise in the Everglades. Knowing that the African rock is bigger and more aggressive than the Burmese python which is about 17 feet long, the â€Å"super snake† would surpass that length. It would not only hamper the ecosystem but would also be dangerous for families with small children. The python hunts by smelling food with its tongue, flicking it up and down. Although the African rock python are already powerful on land, this brainy serpent employs an even more impressive tactic underwater. Ever adaptable, the pythons that reside near water thrive on fish. Much older snakes can use the water to its advantage and hunt greater prey. They can remain under water and every 30 minutes come up to take a discrete breath. It uses heat-sensing organs, called photoreceptors to detect warm-blooded prey. Because the African rock python is non-venomous it squeezes its food. Every time the prey exhales, the python constricts a little more, so that inhalation becomes increasingly difficult. Death is caused mostly by cardiac arrest rather than myths or urban legends articulating that their prey was crushed to death. African rock pythons, as well as every python, are carnivores. Their diet consists of large rodents, monkeys, antelopes, crocodiles, dogs, goats, and poultry . They have strong acids inside their stomach which helps them to digest their food. It is rare of the African rock python hunting for humans. After eating a large animal, the python needs no food for a long time, and may rest for weeks. In this engorged state, it is most vulnerable to attack by predators. In most cases if the snake feels threatened it will regurgitate the food and escape to shelter. African Rock Python becomes sexually active as early as 3-5 years old and reproduce during the spring. The female snake lets out a pheromone which attracts the male snake to mate. During the breeding season both the sexes fast and the female continues the fast till the eggs are hatched. African rock pythons fall under the subclass: protheria. They are oviparous, meaning they reproduce by laying eggs, which hatch outside the mother’s body. Surprisingly the python shows distinct mother instincts by coiling around the eggs, protecting them from predators, and incubating the eggs to help with development until they hatch, which is about 90 days. Which makes this species rather interesting as parenting is quite a foreign concept to reptiles. Hatchlings are between 18–24 inches in length, and have temper when born. Some are known to strike when hatching. They are nearly identical to adults, except with more distinguishing colors. African Rock Python can live up to 12 years in wild however they can live up to 30 years in captivity. It is said that the African rock python is does not run the risk of extinction, but is listed on Appendix II of the Convention on International Trade in Endangered Species (CITES). There is a high demand for the python’s skin and meat in the market, mostly to make leather, belts and purses. Exporting of these exotic animals is known to be illegal. Some of the African rock python’s habitats are also known to be under threat due to destruction for the oil industry. In some cases the African rock python might be a prey to hyenas or the African wild dogs during their digestion period, but aside from humans, adult African rock pythons have very few natural predators due to their large size. For the reason that these species can reach significant sizes, their constricting power must be respected. Most cases found of African rock pythons swallowing a crocodile whole, later to be found that the crocodile was not digested and penetrated the skin of the python. Although this species can easily kill an adult, there are only a few cases in which the victim, in most cases a child, was actually consumed. Rare cases have been reported of an African rock python consuming a 10 year old boy, or attempting to eat a child. In another case a 13 year old was swallowed, but the python was forced to regurgitate the body. The African rock python began being known as â€Å"Man-eating snake†. This factor of their strength, as well as size, separates this python from most other snakes. Maybe even all reptiles for that matter. African rock pythons have been known to go after monitor lizards, which are known to very aggressive and strong. This is one reason why African rock pythons should not be considered a first pet for someone who wants to own a snake. People who are ill-equipped owners or breeders do not know what to expect and end up getting ahead of themselves, and can no longer handle a beast that they just irresponsibly release them, no knowing what their actions have lead to. The African rock python has many fascinating features, from the way they hunt, the way they eat, live, breed, how big of an importance they to the environment not only around animals but humans as well. It’s amazing at how big they can get and to know exactly how powerful they can be. The types of animals they can bring down are twice their size. Their lifestyle captures my attention. Besides the fact, that I am attracted to exotic pets, I own a Royal python, commonly known as a Ball python. Similar to the African rock python, the ball python is considered more docile and smaller in length and hopefully size in the future, but it is still a dangerous animal and should not be handled lightly. This research paper has added to my knowledge of the African rock python as well as other common snakes. I have learned that what may seem to be a harmless hatchling at birth, can grow into an overgrown, powerful killing machine. This is also known as fatal attraction. I know that if I wanted to know release my ball python into the wild I would know how to do it properly. The choice of owning a python, or any snake for that matter , is a choice that needs to be taken seriously, these animals require attention, a stable and healthy living environment, and patience. You never know what to expect from them or when to expect something from them.

The Issue Of Abortion And Abortion - 1115 Words

How would you feel if u weren t given a chance of life and someone decided to just give you up and kill you? Approximately 125,000 abortions occur per day. 1.1 million U.S. abortions each year. Nearly 1 in 4 (22%) of pregnancies end in abortion. 50% of women now seeking abortion have had at least one previous abortion. The U.S. abortion rate is among the highest of developed countries. 51% of abortions are performed on women less than 25 years of age. Approximately 1/3 of American women have had an abortion by age 45. Abortion disproportionately affects black and Hispanic women. (Alan Guttmacher Institute). When it comes to abortion it is one of the most important issues in the world. Some people believe that abortion is sinful because†¦show more content†¦A baby s life begins at conception and it takes away an innocent person s life. Babies shouldn t have to go through this situation just because they can t speak. One study found that â€Å"science teaches that life begins at fertilization.† ( Terzo). The unborn child is not even able to see what life is like. A infant hasn t did anything wrong to be treated in this such act. They don t even have the time to make a mistake or make a decision. It is a law not to murder/kill but apparently not because abortion is a murder. The other reason i m against abortion is because you are going against Christians and what God said. The bible tells us that abortion is bad. According to the Commandments in the Old Testament, it says Thou shalt not kill (Exodus 20:13). This involves guiltless infant babies. When a baby is conceived, God. already knows what is happening. God is the only one to decide when and how a person should die. Which you should not be aborting a child. God makes the choices you don t, especially when it comes to something he doesn t agree on. God gives us life. In Job 1:21 it says â€Å"The Lord Gave, and the Lord has taken away.† He dictates everything and we choose what is right and what is wrong. A child is a person. A person who goes through growth inside and out the wound is a most definitely a person.
