Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0024] The present invention proposes an intelligent gas leakage alarm and automatic gas source cut-off device, such as figure 1 As shown, it includes a wireless communication module, a temperature detection module, a flow detection module, a valve control module, and a central control module. The wireless communication module is connected to the central node, temperature detection module, flow detection module and valve control through 4 wireless communication devices. Module, each module uses the ZigBee protocol to communicate with the central control module; the temperature detection module collects the temperature of the gas equipment, and wirelessly transmits the temperature information to the central node according to the instructions; the flow detection module gas flowmeter communicates with the central node through the ZigBee wireless device The flow da...

Abstract

To quickly and efficiently detect the gas leakage, a concept of Internet of Things is utilized, a thermistor temperature detection technique, a wireless communication technique and an intelligent gasmeter safety cutoff technique are combined, a method using a platinum thermistor for detecting temperature and a Zigbee wireless communication technique for completing quick detection, alarming and automatic cutoff on the gas leakage is provided, and one set of device is designed and built. Proofed by experiment, the device and the method can be used for quickly sensing the gas leakage, automatically and safely cutting off the gas source, and effectively ensuring the long-time gas use safety of a user.

Description

Technical field [0001] The invention belongs to the field of indoor gas leakage detection and alarm, and specifically relates to an intelligent gas leakage alarm and automatic gas source shut-off method and device that combines gas pipeline detection technology and gas appliance state judgment. Background technique [0002] Developed countries abroad have studied pipeline leak detection and location technology relatively early, probably starting in the 1970s, and have formed a relatively mature theoretical system, and entered the practical stage in the late 1980s. It has achieved certain results in terms of positioning and positioning. In the late 1980s, domestic research on pipeline leak detection and location technology was carried out. With the development of computer technology and the introduction of foreign technology, domestic achievements have been made in pipeline detection and location, and they have been successfully applied to some pipelines. . These detection techn...
