Studies On Fire Auto Alarm Control System Based On Fieldbus Technique

With the rapid development of building up economy and city scale expand, various of buildings in the city having increased, although kinds of fire alarm device already obtains the widespread application in building application, fire specially important, super fire disaster still increasing year by year. Especially during the period of Spring Festival.Fire alerting system is a main Part of the modern Building Automation System, and it is always a main Problem in fire Protection field. With the development and application of many industry field-buses, many types of fire alerting system basing upon field-buses are attracting more and more attention. In the paper, aiming at an building of an bank, a new type of fire alerting system basing upon Modbus field-bus is designed. Contra-posing the characteristic of supervisory configuration software, The group state software adopt the ACSEE database and the domestic brand name carries out exploitation. Have brought this both design objective structuring upper advantage, realizing the main body of a book in database into play sufficiently Finally,instantiation the mentality and method of designing through apply the configuration software to the Fire Alarm Supervisory System.According to the characters of fire detection and complex objects of fire detection,the properties of various fire detection system and the reasons of wrong alarm are analyzed. Conclusion is that the key to detect fire accuracy is to enhance the intelligent level of fire detection. Therefore the application of neutral network in dealing with information of fire detection. The network parameters are exercised by forward BP network. Finally, the experiments related to standard test fire indicated that this network can detected various standard test fire accuracy. Three kinds signals have been to check a marriage partner with the temperature, smoke fog and CO gas thickness. Matlab simulation software with input parameters of learning and computing, the conclusion that the output parameters and error. The type of system is in solve misreport, fail to report, intellectualized degree waits for aspect to get satisfactory effect; And, it's structure is apt to be handled good simplely; The product is compared with each other with the present stage same kind, its nature price compares more highly, have vast market place space.
