Zigbee-based wireless borehole pseudorandom monitor device and method

The present invention relates to a wireless zigbee based pseudorandom borehole monitoring device and monitoring method. Based wireless zigbee pseudorandom borehole monitoring apparatus main assembly is made through the USB connection IPC zigbee control unit and a wireless communication unit, the acquisition unit and the wireless zigbee 1,2,3 ...... N wireless communications, each wireless zigbee acquisition unit GPS positioning module has the emitter electrode via the transmission unit is connected with the control unit configured. Pseudorandom as a transmit waveform, increases the accuracy of the test, a pseudo-random sequence having no DC component, its associated function close to a white noise correlation function that is a narrow peak, easily separated from the other signals or interference, has good resistance to interference. Wireless acquisition mode, to avoid the influence of the complex topography data acquisition, the acquisition can not solve the problem of partial data direction; accuracy can be obtained using GPS positioning coordinates of each wireless zigbee acquisition unit; water injection to provide a theoretical plane tone basis, reducing the transfer plane blindness.
