Intelligent fire extinguishing system and method based on distributed pyroelectric sensor network

Abstract

The invention discloses an intelligent fire extinguishing system based on a distributed pyroelectric sensing network. The intelligent fire extinguishing system is composed of a master controller, a rectangular coordinate guide rail, a movement slide rail, a servo motor, a mechanical arm installed on the movement slide rail, a slave controller, the distributed pyroelectric sensing network and a fire extinguishing device; the signal output end of the distributed pyroelectric sensing network is connected with the signal input end of the master controller; the signal output end of the master controller is connected with the signal input end of the slave controller; the motor control signal output end of the salve controller is connected with the control end of the servo motor; the mechanical arm control signal output end of the slave controller is connected with the control end of the mechanical arm; and the fire extinguishing device control signal output end of the slave controller is connected with the control end of the fire extinguishing device. The intelligent fire extinguishing system can monitor the fire behavior of a machine room in real time, prevention and fire extinguishment can be performed fast and efficiently, cost is low, and deployment and maintenance are easy.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to an intelligent fire extinguishing system and method based on a distributed pyroelectric sensor network. Background technique [0002] The defects of the current communication, data and other computer room fire extinguishing methods are specifically manifested in: [0003] 1. The precision of the alarm system is low. Most computer rooms still use low-level smoke alarms, which are not very applicable, have no early warning function, and have a high alarm delay. The alarm is often triggered after an open flame has been generated for a period of time and the fire is obvious. In addition, the probability of misjudgment is also high. . [0004] 2. The fire extinguishing method is unreasonable and the degree of automation is low.

AI Technical Summary

Problems solved by technology

[0003] 1. The alarm system has low precision

Most computer rooms still use low-level smoke alarms, which are not very applicable, have no early warning function, and have a high alarm delay. The alarm is often triggered after an open flame has been generated for a period of time and the fire is obvious. In addition, the probability of misjudgment is also high.

[0004] 2. The fire extinguishing method is unreasonable and the degree of automation is low

The traditional fire extinguishing method is mostly the water sprinkler array on the ceiling layer, which cannot realize fixed-point fire extinguishing. This method wastes water resources, and water will cause permanent damage to equipment.

The fire extinguishing method in the computer room is poorly targeted. If there is an abnormality, the fire extinguishing will be carried out globally, and the fire extinguishing materials cannot be used in a concentrated manner, resulting in huge waste

[0005] Expensive to deploy and huge to maintain

Many computer rooms deploy a set of fire extinguishers for each cabinet, and the entire computer room has a huge collection, resulting in huge deployment and installation costs

In addition, the maintenance cycle of fire extinguishers is short, and fire extinguishing device clusters require frequent and complicated safety maintenance
