specific Embodiment approach 1

[0008] Specific implementation mode 1. Combination figure 1 Describe this embodiment, the computer room DC power supply fire protection system with remote alarm function described in this embodiment, it includes an infrared camera 1, a flame sensor 2, a wireless communication circuit 3, a controller 4, a relay 5, a voltage comparator 6, an isolation Coupling unit 7, logic operation unit 8, output alarm module 9 and sampling resistor R;

[0009] The control signal input and data collection output end of the infrared camera 1 is connected to the camera control signal output and data collection input end of the controller 2, the signal output end of the flame sensor 2 is connected to the flame collection signal input end of the controller 2, and the signal input of the wireless communication circuit 3 The output terminal is connected to the wireless signal input and output terminal of the controller 4, the relay switch control signal output terminal of the controller 4 is connect...

specific Embodiment approach 2

[0011] Specific embodiment two. This embodiment is a further description of the computer room DC power supply fire protection system with remote alarm function described in specific embodiment one. It also includes a signal amplifier, which is connected in series with the total logic operation unit 10 and the control between device 4.

[0012] In this embodiment, the collected signal is amplified, so that the controller can quickly identify abnormal signals.

specific Embodiment approach 3

[0013] Specific Embodiment Three. This embodiment is a fire prevention method using the computer room DC power supply fire protection system with remote alarm function described in Specific Embodiment One. The method includes:

[0014] Collect the voltage value of the sampling resistor when the load is normal as the reference voltage value of the voltage comparator 6. When the load is abnormal and the voltage across the sampling resistor R changes abnormally, the voltage comparator 6 is turned on, and an abnormal alarm signal is output through the output alarm module 9. ;

[0015] After the controller 4 receives the abnormal alarm signal, it sends an alarm through the wireless communication circuit 3, and at the same time controls the infrared camera to rotate to collect the video signal in the machine room, and intercepts the 60-second video signal taken by the infrared camera after receiving the alarm signal, and transmits it through the wireless communication circuit. 3 Sen...

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...
