The Software Design Of Alarm And Control System For Electric Fire Prevention

Along with the rapid development of economy and continuous progress of our society, electricity consumption is increasing, with which electrical fire accidents are also increasing more and more. So related national departments and almost every enterprise attach great importance to electrical fire accidents, and urgently need for a reasonable solution. Alarm and control system for electric fire prevention is a preventative alarm system especially for electrical fire accidents. When the measured parameters of electrical wiring is over the alarm setting value, the system can make alarm and control information, also can point out alarm position. This paper designs and develops an alarm and control system for electric fire prevention based on basic requirements and considering the special requirements in practice.Main tasks in this paper are as follows:Firstly, this paper introduces the whole system and the system software. The system contains site acquisition monitoring layer, communication interface layer, information management layer, and then the paper describes every layer's composition and role. The system support three kinds of communication:RS484 bus, Modbus gateway, wireless. System software is in the information management, including Data Acquisition and Configuration software based on c/s and Web Data Release software.Secondly, this paper describes the implement of the design of the Data Acquisition and Configuration software in detail. This part of software contains configuration module, acquisition module, monitoring module and alarm module. The software supports the three communication ways, and is capable of dealing with alarm.Finally, this paper describes the design of the Web Data Release software in detail. The architecture of the software uses the fashionable SSH framework. Web front page is realized by ExtJS+JSP, and uses Ajax technology, which makes the software stable, open, scalable and also beautiful.Through a long period of testing, the software is stable, and its data is secure and reliable, so the software meets the requirements of industry.
