| 摘要 |
The invention concerns a method, device and system for detecting buried services (1) by electromagnetic means with introducing an artificially generated electrical detection signal (5) indirectly via soil (12) to the buried service (1), detecting an electromagnetic field (4) originating from the introduced underground detection signal (5), which is preferably following along the buried services (1), by a mobile detection unit (3) above ground, and determining the proximity of the structure (1) to the detection unit (3) according to the detected electromagnetic field (4) of the detection signal (5). Therein, the soil conducted detection signal (5) is supplied via a mains socket (8). |
