Intelligent gas safety linkage control system based on Internet of Things

Abstract

The invention relates to the technical field of gas related equipment, and particularly discloses an intelligent gas safety linkage control system based on the Internet of Things, which comprises a gas meter and an alarm, a methane sensor and a wireless communication module are arranged in the alarm, and the methane sensor is wirelessly connected with the gas meter through the wireless communication module; a self-control valve, a valve control module, an Internet of Things module and an LCD display module are arranged in the gas meter, a gas connecting pipe is arranged in the gas meter, a gas inlet pipe and a gas outlet pipe are arranged on the left side and the right side of the gas connecting pipe respectively, and the self-control valve is installed on the gas connecting pipe and controlled through the valve control module. The alarm is in wireless connection with the gas meter and the mobile phone through Bluetooth / Lora and the like, gas user meter end data information is collected and uploaded to an intelligent platform of a gas company for supervision, when faults and alarm conditions occur, the platform can obtain fault information at the first time, a meter valve can be remotely turned off through the valve control module, and the safety of products is ensured.

Description

technical field [0001] The invention relates to the technical field of gas-related equipment, in particular to an intelligent gas safety linkage control system based on the Internet of Things. Background technique [0002] When combustible gas leakage occurs in the daily gas environment, the alarm will sound and light alarm to remind personnel to take measures such as evacuation, ventilation and shutdown of equipment. At present, there are two kinds of alarms on the market, the traditional wired gas alarm and the Bluetooth alarm with several functions. [0003] There are two kinds of alarms on the market at present, the traditional wired gas alarm and the Bluetooth alarm with single function. The disadvantages of the two gas alarms are as follows: [0004] a. Wired gas alarm: high requirements for on-site installation conditions, difficult construction and installation; high cost; the connection line with the shut-off valve is easily damaged by external force; poor aesthet...

AI Technical Summary

Problems solved by technology

[0004] a. Wired gas alarm: high requirements for on-site installation conditions, difficult construction and installation; high cost; the connection line with the shut-off valve is easily damaged by external force; poor aesthetics, need to install sockets on the wall, some users consider beauty and convenience, the alarm Without plugging in or connecting, the alarm cannot play the detection and alarm function;

[0005] b. Bluetooth alarm: single function; can only send alarm signal, can not monitor the status of the alarm; only alarm when the concentration exceeds the preset threshold, can not make a judgment on the slight change of the concentration; false alarm of gas leakage The probability is high, and the accuracy of the remote self-inspection of the alarm and the judgment of gas leakage still need to be further improved
