R & D Of Intelligence Residence System Based On Lon Works Bus

With China's rapidly increasing economic and technological level, the Internet became popular, especially in computer technology, communication technology, network technology and the rapid development of control technology, which greatly promoted the modernization of home, these high-tech to improve the quality of life for people providing a new lifestyle: working, if not trust the security of home, home monitoring via the Internet in a safe condition; daily commute can be controlled via the Internet at home air conditioners, refrigerators and other equipment, these are just smart home A simple miniature.This bus appears at the scene for several decades, from the original factory applied to the current used in homes, during a long walk, we now both live in the factory or the smart home devices have undergone fundamental changes , had originally conceived as a piece of equipment in the factory when problems arise, technicians can do to the scene, they can solve most problems. Although it is the integration of fieldbus communications and a variety of sensing technologies and emerging technologies, but the field bus technology development so far there is no uniform standard, so when the factory in the field bus technology to a family, there will be no uniform standard, not compatible with other issues, but this does not affect the development of field bus, the future these issues will certainly be resolved.Studied in this paper is developed by the United States and Egypt Lon Works Shi Lang bus, the core components that have a processing capacity of both communication Neuron Chip. The emergence of such a bus overturned in the past the bus in the form, can be better integrated into the bus to go home. In this article, only the smart home involves two parts, one is the three-copy form, and the other one is an access control system.(1) For the three-copy form to the field bus for the operating platform, to power lines as the transmission medium constitutes a current meter reading system. Used due to the current power meter, water meter, gas meter, heat meter, etc. are based on the RS-485 interface, so this just shows the power meter data, copy, and put much energy meter data management center to pass residential property .(2) In the access control system, full use of the GPRS network to the popular image transmission, when strangers visit, triggering the alarm, the stranger the image data through the GPRS network will be sent by MMS to the original to the set phone number in.Lon Works on the characteristics of the bus, in this paper as a collector of each intelligent node, an intelligent node can copy 32 RS-485 interface with the meter. And equipped with batteries to prevent accidental power-down errors when reading data. In the upper monitor is used on the three VB visual programming to read the data tables and timely save. Extended application for the future users may also be viewed in real time through the WEB of the household electricity and water and so on.
