Design And Realization Of Substation Communication Machine Room Monitoring System Based On ZigBee And GPRS Technology

Intelligent security system connect various security facilities(such as human body infrared detectors,water monitoring,cameras)together through the network in the use of computer,communication network technology and embedded systems,it provide reliable security guarantee for a particular environment with the real-time monitoring and alarm information sending at any time.Traditional security system work like this:security person view monitor screen all the day,and field patrol is need in specific time,all the abnormal accident is found by person.Such as this,traditional security system need a lot of security person,it will cost a lot of money in employing people,at the same time,same abnormal accident can not be found in time.Intelligent security system will solve the problem,it will reduce labor costs to achieve more effective safety protection.In this paper,the method of intelligent security system is studied in this paper,and the system design is carried out for the 220kV xx substation equipment communication room in baise area.This research study intelligent security system based on ZigBee and GPRS,and it's core hardware platform is S3C2440 microprocessor.system implementation of the key technologies involved in are studied and discussed.In the whole design,the main work is as follows:1.The circuit module is based on CC2530 chip,use ZigBee protocol stack to realize the coordinator between the terminal and the structure of the star network mode,finally transfer data from the terminal to the coordinator.2.The ZigBee coordinator control GPRS module to transfer the data collected and the state of the actuators to the ARM processor.3.The research analyze related technologies for the ARM processor and Linux kernel,building the system hardware and software development platform,analysis the Boot Loader start principle and operation process,etc.4.The research realize the function of the overall system requirements such as completing the design of the Web server and configuration,realizing intelligent security system function and adding video monitoring function.
