Description

Technical Field

[0001] The invention specifically relates to an infrared human body detection feedback device. Background Art

[0002] The automatic fire extinguishing control system is an important alarm and fire extinguishing measure for controlling fire fighting. With the development of economy and electromechanical intelligence, more computer rooms are forced to be built. Computer rooms are the gathering place of precision electronic equipment. Computer rooms are prone to fires due to excessive load, untimely replacement of old equipment, and battery fire. If the fire in the computer room is not handled in time, it is easy to cause great losses. In order not to affect the internal equipment, the fire extinguishing equipment in the computer room generally uses gas fire extinguishing devices. The fire extinguishing agent in the gas fire extinguishing device has good insulation, is not conductive, is easy to vaporize, and will not leave any residue. It can be completely vaporized in a very short time. Therefore, for computer rooms that store high-precision electronic equipment, professional gas fire extinguishing devices should be used.

[0003] At present, the fire extinguishing systems on the market can generally be controlled in two ways: automatic and manual. As a fire extinguishing system that protects high-value property and important places, the gas fire extinguishing system is not suitable for people to be in the room when spraying the fire extinguishing agent. The common way to deal with it is to manually set the system to manual mode when there are people inside. Although this method meets the use requirements to a certain extent, if the person forgets to set the fire extinguishing system to automatic mode when leaving, the fire will not be extinguished, endangering the property and personal safety.
