ABSTRACT:
Methods and apparatus are provided for receiving, detecting and transmitting geophysical data from a plurality of electrodes inserted through a structure's pavement foundation in a non-destructive manner and into the soil utilizing a dynamically reconfigurable wireless control unit located on each electrode. Data from the control units is transmitted by a wireless signal to a centralized data processor for analysis. Control data is provided from a central control processor to the control unit by wireless transmission. The control unit, which is positioned, includes a multi-channel radio frequency transmitter/receiver and a processor to actuate relays and record data returns from the measured substrate soil for transmission to the central data processor. The control unit incorporates a changeable code or address to unambiguously identify itself, and its spatial relationship to other electrodes, to the central data processor and the central control processor. The control units are equipped with a GPS positioning device to allow for automatic transmission of electrode location and for electrode placement without a manual survey being required.
