Desgin And Implementation Of Online Monitoring And Alarming System For Residence Based On Internet

City development makes people live and work more and more concentrated,due to short time,long continuous cycle,serious consequences,fire has become the most important accident threatening and endangering the safety of life and property of residents,fire alarm in time and evacuation of residents is an important means of reduce the loss.Traditional fire monitoring alarm system adopts wired data transmission or LAN,can not notify the high-rise residents escape in the first time,and also has problem like high cost,not timely.In view of the above problems,this paper proposes a monitoring alarm system based on Internet,monitoring the fire point parameters of each unit in the apartment online,it can be the first time to alarm and inform all residents to escape when detecte fire.According to the requirements of the domestic security city project,this paper has completed the hardware design of the fire online alarm system,data acquisition and wireless communication module,as well as the software design of the data online display and alarm module.The lower machine data acquisition module by driving the sensor to accomplish the function of detecting indoor temperature and smoke;wireless communication module controlled by MCU,realizes the wireless transmission of data to the remote server;Online display module is responsible for displaying wireless transmission data page,residents and management staff can view each unit apartment room at convenient;Data alarm module can filter out the abnormal room through anomaly detection algorithm,Nagios monitoring software used for real-time monitoring,and send alarm notification to all residents.This paper mainly describes the working principle of online monitoring alarm system design,introduces temperature,smoke and gas acquisition module;Design TCP server and Web server;GPRS technology is adopted as the upper and lower data communication scheme;Design Nagios monitoring and alarm service.Study and used for anomaly detection algorithm to realize the fire detection.Finally,the monitoring and alarm functions of the system are verified by experiments.This product uses GPRS network for data transmission directly,does not rely on special network,and based on the cheap chips,such as STC89C52 RC MCU to make full use of,the cost is low,suitable for widely installed in the residential,apartments,companies and other occasions.
