Gas fire-extinguishing monitoring system based on internet of things

Abstract

The invention belongs to the technical field of the internet of things-based applications for gas fire-extinguishing facilities and provides a gas fire-extinguishing monitoring system based on the internet of things. According to the technical scheme of the invention, an internet-of-things user information device is used for acquiring the information of a steel cylinder pressure gauge arranged on the bottle head valve of a gas fire-extinguishing agent container through a video acquisition terminal. The acquired information is transmitted to the internet-of-things user information device and then the pressure change in a gas collecting pipe is sensed by a pressure sensor arranged on the gas collecting pipe. The information transmitted to the internet-of-things user information device is uploaded to a fire-extinguishing facility internet-of-things application platform to be monitored remotely through a network layer. The system has the functions of automatic monitoring, pressure information acquisition, information transmission and the like. The system also has the function of pressure display.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things application for gas fire protection in fire protection facilities, and in particular relates to a remote monitoring system for maintenance and management of gas fire protection. Background technique [0002] In fire-fighting facilities, gas fire-fighting is one of the main methods to protect valuable equipment, and it is particularly important to pay attention to the usual maintenance and management of gas fire-extinguishing systems. Conventional gas fire extinguishing systems include heptafluoropropane gas fire extinguishing system, IG541 gas fire extinguishing system, carbon dioxide gas fire extinguishing system, etc. The gas fire extinguishing agent has certain requirements in the selection of fire extinguishing places. It causes less secondary damage to the protected objects after fire extinguishing, but the storage pressure of the fire extinguishing agent is relatively high, and th...

AI Technical Summary

Problems solved by technology

However, it also has a great impact on the installed steel cylinder system, especially the quality of the fire extinguishing agent is affected by the ambient temperature, and there are certain problems in the accuracy of its weighing accuracy.

In addition, the current research on gas fire monitoring is only limited to whether the gas fire extinguishing agent in the gas fire cylinder is leaking. In the fire extinguishing state, whether the bottle head valve can be opened normally and the pressure in the gas pipe network are not reflected in the parameters of the results.
