Abstract

The invention discloses a signal collecting and monitoring system based on a wireless node network. A field terminal subsystem comprises a plurality of technological parameter collecting devices and a plurality of video collecting devices, and technological parameter data and video image data in a coal bed gas production well are collected; a wireless backbone network subsystem comprises a plurality of wireless receiving-dispatching node devices and a wireless receiving-dispatching root node device, all the wireless receiving-dispatching node devices are connected with the technological parameter collecting devices and the video collecting devices arranged in the coal bed gas production well, receive the technological parameter data collected by the technological parameter collecting devices and the video image data collected by the video collecting devices, and send the received technological parameter data and the received video image data to the wireless receiving-dispatching root node device, wherein when a wireless communication link between a certain wireless receiving-dispatching node device and the wireless receiving-dispatching root node device is blocked, the wireless receiving-dispatching node device carries out wireless communication with the wireless receiving-dispatching root node device through the adjacent wireless receiving-dispatching node device.

Description

Technical field [0001] The invention relates to the field of monitoring of coal-bed methane production wells, in particular to a signal acquisition and monitoring system based on a wireless node network. Background technique [0002] Coalbed methane is commonly known as "gas". It contains methane as the main component, mainly adsorbed on the surface of coal matrix particles, partially free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal. Unconventional natural gas. The calorific value of 1 cubic meter of pure coalbed methane is equivalent to 1.13kg gasoline and 1.21kg standard coal. Its calorific value is equivalent to natural gas. It can be mixed with natural gas and is very clean after combustion. It hardly produces any waste gas. It is a good fuel for industry, chemical industry, power generation and residents. However, its mining, gathering and transportation technology is difficult, and construction and operation costs are high. ...
