Signal acquiring and monitoring system based on wireless node network

摘要

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.
