Computer room direct-current power source fire protection system with remote alarm function

Abstract

The invention relates to a computer room direct-current power source fire protection system with a remote alarm function and belongs to the wireless alarm technical field. With the system of the invention adopted, prevention of fires caused by arcing and sparking due to poor contact and short-circuiting of an equipment power supply voltage system can be realized. According to the computer room direct-current power source fire protection system of the invention, the control signal input and acquisition signal output end of an infrared camera is connected with the camera control signal output and acquisition signal input end of a controller; the signal input and output end of a wireless communication circuit is connected with the wireless signal input and output end of the controller; a sampling resistor R is connected in series between a relay and computer room server equipment; two ends of the sampling resistor are connected with two voltage signal input ends of a voltage comparator; the voltage signal output end of the voltage comparator is connected with the signal input end of a logic operation unit through an isolation coupling unit; the signal output end of the logic operation unit is connected with the signal input end of an output alarm module; and the abnormal signal output end of the output alarm module is connected with the alarm signal input end of the controller. The computer room direct-current power source fire protection system of the invention is suitable for computer rooms.

Description

technical field [0001] The invention belongs to the technical field of wireless alarm. Background technique [0002] Due to the dry environment and numerous electrical appliances in the computer room, it is very easy to catch fire. The servers in the computer room will be burned down, and at the same time, the power supply of the entire area will be interrupted, causing major economic losses. The phenomenon of sparking, the spark caused causes the board and cabinet to catch fire and burn the computer room. Although the current computer room equipment is equipped with smoke alarm equipment, it must be activated when there is smoke in the fire, which cannot effectively prevent the occurrence of fire phenomena. Contents of the invention [0003] The present invention is to realize the prevention of the fire caused by the short circuit of the equipment power supply voltage system and the phenomenon of sparking and sparking due to poor contact, and proposes a DC power supply f...
