Home automation eHouse .Building Automation eHouse works on industrial serial bus RS485 .Building Automation Controllers eHouse with RS485 interface:
Bus 485This is similar to the 232 bus (software), however, all devices are addressed and work alternately and exchange information only with the main host (server) .Each transmission line RX and TX is replaced by a pair of differential lines (RX + , RX - ) And (TX + , TX - ) , where the signal is processed by RS232 to RS485 converters . The use of differential line allows you to:
EHouse a bus based on the 485 works in full duplex mode, meaning , that pairs of TX and RX lines are not shorted together , but a separate pair of lines is the transmitted signal to the host root , followed by a separate pair of signal reception from the host root . This architecture significantly reduces the possibility of a collision on the RS485 bus . Suitable device - eHouse smart home controller driver activates the transmitter 485 only when sending data to the host root , after ensuring , other devices that do not fit at the same time . All devices operate at maximum eHouse 115200 parity (E) and 1 stop bit . Velocities do not change , because it can lead to too much strain RS485 (with too low speed devices) . EHouse a bus can only connect one device eHouse system , which must have the same transmission protocol set . Connecting other equipment can cause transmission errors or total damage to the drivers 485 , due to specific hardware, and "data frame" eHouse a protocol . EHouse data bus connection to PC 1 , performed using RS232 converter - 485 . No PC connection allows for full (local) work of all drivers , However, without the possibility of transferring data between controllers , and receive commands from other communications media for system management . Gateway to the world are implemented through management software , Control and communication home smart eHouse Local and remote control is implemented through the Windows XP software suite . . 7 by the following transmission media:
The included software package also allows the management and control of building automation through the Windows file system (copying files to the queue directory events) . This allows you to create your own control software algorithms , if you need to implement additional functions in relation to the standard version of the system . Using Windows as a file system interface to the intermediary data transmission allows the driver eHouse very easy to create your own software based on the log analyzer software building automation eHouse and write files to the queue system events eHouse , without having to create low-level software to broadcast 485 . Advantages and disadvantages of using the RS485 interface for communication:
