| titleOfInvention | An underground cable detection method based on charge induction |
| abstract | The invention provides an underground cable detection method based on charge induction, which is characterized in that three electrodes are placed on the same plane in a triangular arrangement, and connected to three charge sensors respectively, and the charge sensors are connected to a collection and processing module; The array scans parallel to the ground under test, and the three metal detection electrodes sense the change of the ground electric field at the same time, and then the charge sensor converts the induced charge into a voltage. Determine the location and direction of the buried cable, and finally calculate the buried depth of the cable. Its significant advantage lies in the use of three electrodes to sense the electric field generated by the ground wire cable to realize the change of charge generated by the detection of the position, direction and buried depth of the ground wire cable. External factors such as electrical constant and cable current carrying capacity do not need to actively apply signals, and the detection depth can reach 4m. |
