Title:
PIPELINE DETECTION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/047621
Kind Code:
A1
Abstract:
A pipeline detection device and method, used for an automobile piping system. A main pipeline (1) of a piping system communicates with male joints (3, 8) via connecting terminals (6, 11); conductive structures (2, 5, 9) are provided at the connecting terminals (6, 11); a positive terminal of a detection line (10) is connected to a power terminal of an ECU of an automobile (100), and a negative terminal of the detection line is connected to a ground terminal of the ECU (100). When the connecting terminals (6, 11) correctly connect the main pipeline (1) and the male joints (3, 8), the conductive structures (2, 5, 9) are turned on, so that the detection line (10) and the ECU (100) form a current loop to detect, on the basis of voltage on the detection line (10), whether an abnormality occurs in the pipeline system.
