Research On Intelligent Fire Control System

Along with the development of our technology and the social economy, modern construction becomes higher and more and more complex. So fire accident occurs frequently, and it causes huge casualties and economic losses. People’s awareness of the fire accidents increasing and the need of prevention of fire becomes more. Due to the traditional fire control and the lack of intelligence, false alarm rate is high and efficiency of the prevent of fire accidents is low. It can not meet the need of the national standards and the prevent of fire, so it is very important for us to research the intelligent fire control system.This paper puts forward the overall design scheme of intelligent fire control system. In this design, the intelligent and composite fire detector are adopted to collect the characteristic parameters of fire and make the fire information more accurate and reliable. The STC15F2K60S2 single-chip is used to enhance the function of fire alarm and linkage. And it has replaced the original ordinary MCU as fire alarm controller and fire linkage controller of the intelligent fire control system.In this design, the node of the intelligent fire control system are been networking to achieve the networked of the intelligent fire control system and to improve the reliability of intelligent fire control system. In the process of networking, CAN bus technology is adopted and the CAN232 MB intelligent protocol converters is linked to PC by communication.The Intelligent fire alarm judge comprehensive algorithm integrates the threshold value comparison method and slope determination method and makes full use of the powerful processing function of modern computer. By the correction,compensation and judgement of the characteristics of fire parameters, the false positives and non-response rates of the fire are reduced. The VB is used to realize the the Intelligent fire control monitoring interface.And by the Intelligent fire control monitoring interface, we can master the scene of the fire dynamics and record the fire information in time and make the fire-fighting scheme quickly and efficiently to complete fire mission. In conclude, the use of the Intelligent fire control monitoring interface has improved the efficiency of the fire-fighting.In this paper, the application of fire-fighting DC 24 v power supply problem in fire detectors, fire manual control device and fire proof valve is mentioned. And by the engineering example analysis and calculation, the problem and shortage of fire-fighting DC 24 v power supply is analyzed. And in the end of the paper, the correct and reasonable solution is put forward to perfect the intelligent fire control system further.
