Development Of A New Type Of Gas Fire-extinguishing Controller

The fire controller is one of the core components of automatic alarm fire extinguishingsystem which is being used to monitor fire. The good or bad design of the controller haves adirect impact on the efficiency of fire extinguishing.The controller designed with goodperformance is the basis of the fire extinguishing system for higher extinguishing efficiencyand greater economic efficiency.First, there is a description about the current situation of the development of the gas fireextinguishing controller, comparing the advantages and disadvantages of a variety of relatedproducts. Through further learning the MCU control theory, according to the designrequirements for fixed gas extinguishing controller, the design scheme of a new gasextinguishing controller based on MCU are provided.Secondly, this article haves a detailed introduction about specific functions of the newcontroller, the hardware design and software implementation. This controller chooses theC8051F340MCU with high-performance as the microcontroller; the LCD display shows thestatus and parameter settings; the composition of the controller also includes a conversionaland detectional power、the motherboard linkage control part、sound and light alarm、real-timeclock.The control software was programed by Keil C51, which is a software developmentsystem, and the emulator EC2or ML-EC3is used to debug the control software.Finally, the controller is manufactured to doing tests. Electromagnetic compatibilitytesting and environm testing are introduced to verify the feasibility and stability of thecontroller.The controller can simultaneously meet the requirements of the control and use of CO2、HFC—227ea、gasoloid fire extinguishing products. By simply setting and adjusting program,the controller can achieve the necessary control of the different fire-fighting products,thecontroller has advantages of simple operation and beautiful user interface at the same time.Sothe fire extinguishing controller is widely used in the fire service industry, has a broad marketspace and development prospects. This topic is a project with the cooperation of sichuanqisheng fire fighting equipment manufacturing company, at present the product has passedthe certification of national public security fire extinguishing controller industry detection,has been put on the market.
