Abstract


Ceiling-mounted automatic fire extinguishing system development, this paper system to carry out the automatic fire alarm controller , the linkage device design , production, system associated reconcile optimization . Joint design methods to overcome the shortcomings of the past alarm controller and linkage system designed separately , to achieve good compatibility between the two , and to meet not intermittent use of the workplace and the upgrade and maintenance ; controller ARM7 platform with large-size LCD display with touch screen designed the alarm controller hardware and software , to achieve a fast and convenient mode of operation and intuitive display interface ; design drives compatible detectors on the market , making the selection of a variety of advanced detection system become possible ; FET drive timesharing output means , so that the design of the fire extinguishing devices starter with a large - capacity output capability ; protected areas hanging fire extinguishing devices , pharmaceutical placed directly above the protection of the scene , making the system from the discovery shorten the time of the fire to the pharmaceutical release within 3 seconds ; using interrupt signal response , in order to achieve the partition function , the scope of protection can be divided according to the time of the protected areas . While achieving a rapid response to the fire signal ; no method for the design of the pipe network , eliminating the need for conventional fixed fire extinguishing system in the complex piping and high - pressure storage device, reduce the pressure requirements of the pipeline and valve , thereby facilitating reduce the use and maintenance costs .
