Embodiment 1

[0042] Embodiment one, such as figure 1 As shown, a multi-station fusion power room intelligent gas fire extinguishing system includes an upper computer 2, a lower computer 3, a temperature sensor and three high-pressure gas tanks 4 installed in the cabinet, and CAN is used between the upper computer 2 and the lower computer 3. Bus for communication connection, such as Figure 4 As shown, the bottom of the high-pressure gas tank is provided with an intake valve 6 and a differential pressure control valve 5 located at the exhaust port of the high-pressure gas tank. The differential pressure control valve 5 is connected to the high-pressure gas tank; It is connected to the high-pressure flame-retardant gas chamber 7, and the other end of the intake valve 6 is connected to the high-pressure gas tank; both the intake valve 6 and the differential pressure control valve 5 are connected to the lower computer 3; the high-pressure gas tank is filled with a set pressure v 0 The high-pr...

Embodiment 2

[0057] A control method for an intelligent gas fire extinguishing system in a multi-station fusion power room, this embodiment is an alternative to Embodiment 1, as shown in figure 2 As shown, in this embodiment, when a fire occurs and the lower computer is used to control the opening of the intake valve, the lower computer uses a fuzzy PID controller, including:

[0058] a) Set the PID parameters of the fuzzy PID controller, the PID parameters include the proportional value K P , integral value K I and differential value K D , set the controller temperature given value T 3 , the current feedback signal T with an output range of 4 to 20mA is detected by the temperature sensor 1 , which is converted into a digital signal by the data acquisition card through the A / D converter, and the deviation signal e=T is obtained 3 -T 1 ;

[0059] b) using the deviation signal e as the input of the fuzzy PID controller, and obtaining the deviation signal range EP according to the pres...

Abstract

The present invention relates to the field of fire extinguishers, and discloses a multi-station fusion electric machine room intelligent gas fire extinguishing system and method, including an upper computer, a lower computer, a temperature sensor and a high-pressure gas tank installed in the cabinet, and the high-pressure gas tank is equipped with an air intake valve and The differential pressure control valve located at the exhaust port of the high-pressure gas tank, the differential pressure control valve is connected with the high-pressure gas tank; the intake valve is located at the bottom of the high-pressure gas tank, and one end of the intake valve is connected to the high-pressure flame-retardant gas chamber through the air guide tube. The other end of the intake valve is connected with the high-pressure gas tank; both the intake valve and the differential pressure control valve are connected with the lower computer; the high-pressure gas tank is filled with high-pressure flame-retardant gas. The invention not only intelligently controls the opening of the intake valve, but also has a pressure difference control valve on the fire extinguishing tank, which can quickly extinguish fire in real time by monitoring the pressure difference inside and outside the fire extinguishing tank.

Description

technical field [0001] The invention relates to the field of fire extinguishers, in particular to an intelligent gas fire extinguishing system and method for a multi-station fusion electric machine room. Background technique [0002] The power computer room plays a very important role in the power system. The equipment in the computer room of the electronic information system is complex and asset-intensive. It is necessary to ensure the normal operation of electronic equipment. Large and static electricity, etc. Once a fire occurs in the computer room, it will cause major losses and chaos in the order of power dispatching. Therefore, the fire protection system is an indispensable guarantee for the power computer room. [0003] For example, a "fire extinguishing system" disclosed in Chinese patent literature, its announcement number is CN207024430U, the utility model includes a fire extinguisher, a solenoid valve, a cable, a fire detection controller, a power supply, and the ...
