Design And Implementation Of Computer Room Environment Monitoring System Based On ZigBee Technology

Social development over the years, all kinds of technology to the development of the Internet along with the social demand of iteration by continual development. All kinds of monitoring and control system from the traditional artificial monitoring also constantly to intelligent unmanned monitoring system, so in order to meet the school,company, telecom room, and even personal family, convenience and safety of real-time monitoring and control system is more and more attention by people. We need to consider or server security monitoring equipment, all kinds of work environment is in line with the standard, in the case of a limited cost how both can achieve data transmission timeliness and can guarantee the validity of data transmission, so the problem has become the current hot issues. The content of this research is mainly to build simple, low cost and can solve the real time collect the various data of environment monitor system, to achieve communication staff at any time at any place convenient access to or control the corresponding equipment, improve the work efficiency.Through study encountered in the work of monitoring and control system, and access to a lot of all kinds of information about environmental monitoring system,personally think that higher feasibility of solution is: the board room is a small room for wireless networking, through the mature and stable data gathering center, equipment and network game point can be room temperature and humidity, smoke, entrance guard,air conditioning, fire control system and so on carries on the real-time detection,acquisition of effective information uploaded to a powerful management functions of data management center, it can implement the data summary, induction and control, at the same time can be saved, analysis, and even line alarm function, general this kind of data management center in the machine room is recommended to use embedded platform management center. Finally also can through the form of remote access to the data from the monitoring system, analysis the content, and even warning distance query and management. So this thesis mainly includes four aspects: the wireless network, data,data management center, the embedded server and access procedures.This article is based on working experience, the use of low-cost Zig Bee(shortdistance, low power consumption) wireless technology, on-site environmental monitoring equipment, I undertake in this thesis focus on secondary development of Zig Bee wireless protocol stack, through the integrated development environment IAR program to realize node Zig Bee(CC2530 module USES Ti) sensor data information,and through CC2530 comes, the features of the wireless transceiver used during the data transmitted to the gateway protocol 802.15.4 nodes through the A/D conversion circuit of D/A conversion. Second, write the gateway program the gateway to collect data through the serial port RS232 / RS485 is sent to the embedded system. Local direct engineering machine or computer via the WEB application for remote invocation,realizing remote equipment check and control on the environment.
