A Signal Acquisition and Monitoring System Based on Wireless Node Network

Abstract

Abstract: The present invention discloses a signal acquiring and monitoring system based on a 5 wireless node network. The on-site terminal subsystem comprises a plurality of process parameter acquiring devices and a plurality of video acquiring devices, which acquire the data of process parameters and image videos in the wells producing the coal bed gas; the wireless backbone network subsystem comprises a plurality of wireless transceiver node devices and one wireless transceiver root node device, each wireless transceiver 10 node device is connected with the process parameter acquiring devices and video acquiring devices set in the wells producing the coal bed gas, and receives the process parameter data and the video image data acquired by them; and the received process parameter data and the received video image data are transmitted to the wireless transceiver root node device; Wherein, a certain wireless transceiver node device will be 15 wirelessly communicated with the wireless transceiver root node device via its adjacent wireless transceiver node devices, when the wireless communication link between the certain wireless transceiver node device and the wireless transceiver root node device is blocked.

Description

technical field [0001] The invention relates to the monitoring field of coalbed methane production wells, in particular to a signal acquisition and monitoring system based on a wireless node network. Background technique [0002] Coalbed methane, commonly known as "gas", exists in coal seams with methane as the main component, mainly adsorbed on the surface of coal matrix particles, and partially free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal. For unconventional natural gas, the calorific value of 1 cubic meter of pure coalbed methane is equivalent to 1.13kg of gasoline and 1.21kg of standard coal. Its calorific value is equivalent to that of natural gas. It is a good fuel for industry, chemical industry, power generation and residential life. However, its mining, gathering and transportation are technically difficult, and the construction and operation costs are relatively high. [0003] Coalbed methane has production char...

Problems solved by technology

One of the main reasons is the communication network link problem in the well area, that is, the well site process data / video data cannot be uploaded to the central control room, and the control commands of the central control room cannot be downlinked to the well site
