Problems solved by technology

Moreover, the danger of methane gas is that it is a flammable and explosive gas, and it is very easy to explode when it encounters a heat source and an open flame.
Therefore, the monitoring of methane gas has always been a matter of great concern to people. There are various monitoring instruments and devices on the market, but these mainly use electrochemical methane sensors, which have short service life and low accuracy.
[0003] In related technologies, remote wireless methane concentration monitoring systems are generally based on Bluetooth, ZigBee, WiFi and other communication technologies to transmit data, but due to the defects of large data flow, limited networking computing capacity, and large battery consumption, it is difficult to popularize in a wide range application

Embodiment Construction

[0029] Hereinafter, the structure and function of the present invention will be described in detail based on the drawings illustrating the preferred embodiments of the present invention.

[0030] NB-IoT (Narrow Band Internet of Things, Narrow Band Internet of Things) technology, as an emerging data transmission technology, has wider technical coverage and can improve indoor coverage. In the same frequency band, NB-IoT is better than the existing Bluetooth, ZigBee, and WiFi The network gain is 20dB, and the coverage area is enlarged 100 times. At the same time, NB-IoT has the ability to support massive connections. One sector of NB-IoT can support 100,000 connections, supports low latency sensitivity, and greatly reduces equipment costs and operation and maintenance costs by reducing equipment power consumption and optimizing network architecture. , Saving huge manpower, material resources and financial resources. Compared with GPRS (General Packet Radio Service, General Packet R...

Abstract

The invention provides an NB-IOT(Narrow Band)-based intelligent wireless methane monitoring device, a system and a method. The device can comprise a main control MCU, an NB-IOT module, a methane sensor, a GPS chip and a sound-light alarm module,the NB-IOT module, the methane sensor, the GPS chip and the sound-light alarm module are all communicated with the main control MCU through serial ports, and the main control MCU receives methane concentration obtained by monitoring a to-be-detected environment through the methane sensor, controls the GPS chip to obtain position information of the to-be-detected environment and controls the NB-IOT module transmit the methane concentration and location information to a data and service center on the Internet of Things cloud platform through a transmission network; and the main control MCU controls the sound-light alarm module to give an alarm when the methane concentration reaches a preset threshold value.

Description

Technical field [0001] The present invention relates to the field of intelligent detection, in particular to an intelligent wireless methane monitoring device, system and method based on NB-IoT. Background technique [0002] With the improvement of people's living standards and the rapid development of industry, there are more and more safety issues related to methane gas. When the methane concentration is too high, it is easy to cause suffocation and death. Moreover, the danger of methane gas is that it is a flammable and explosive gas, which is very easy to explode when exposed to heat sources and open flames. Therefore, the monitoring of methane gas has always been a matter of great concern to people. There are various monitoring instruments and devices on the market, but these mainly use electrochemical methane sensors, which have short service life and low accuracy. [0003] In related technologies, remote wireless methane concentration monitoring systems are generally based...
