Title:
SENSOR SYSTEM FOR ELECTRIC POTENTIAL GRADIENT MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2023/201948
Kind Code:
A1
Abstract:
A sensor system for electric potential gradient measurement. The sensor system comprises an electric potential gradient measurement apparatus and a mobile terminal. First alternating-current/direct-current electric potential signals and second alternating-current/direct-current electric potential signals of two mark points above a buried pipeline (10) are respectively measured multiple times in the direction of the buried pipeline (10) by means of a primary dowsing rod (100) and a secondary dowsing rod (200) of an electric potential gradient measurement apparatus; and first feedback data with first alternating-current/direct-current electric potential gradient data and second feedback data with second alternating-current/direct-current electric potential gradient data are respectively measured and sent to a mobile terminal by means of voltage gradient sensor modules (120, 220) in the two dowsing rods (100, 200), such that a detector performs determination. In the sensor system for electric potential gradient measurement, two devices, i.e. an alternating-current electric potential measurement apparatus and a direct-current electric potential measurement apparatus, can be replaced with an electric potential gradient measurement apparatus which includes voltage gradient sensor modules (120, 220), such that it is more convenient for a detector to perform safety detection on a buried pipeline (10).
