Wiring type pipe monitoring system

Abstract

The invention discloses a wiring type pipe monitoring system. The system comprises monitoring equipment, a diode and a pipe measuring line, wherein a first end of the pipe measuring line is connectedwith an anode of the diode; a cathode of the diode is connected with a first end of a to-be-measured pipe; a second end of the pipe measuring line and a second end of the to-be-measured pipe are separately connected to the monitoring equipment to form a loop; the monitoring equipment transmits current signals to the pipe measuring line; and whether the to-be-measured pipe is abnormal or not according to the feedback condition of the current signals; the monitoring equipment comprises a comparison circuit; and when the to-be-measured pipe leaks, the monitoring equipment measures voltage in theloop so that the leakage resistance of the to-be-measured pipe can be determined during leakage. According to the disclosed wiring type pipe monitoring system, the diode is connected between the pipemeasuring line and the to-be-measured pipe, abnormity of the loop is monitored according to feedback conditions of transmitting current signals, the problem that in the prior art, only short-circuiting can be monitored is solved, and workers can be timely notified to repair equipment.

Description

technical field [0001] The invention relates to the field of pipeline leakage monitoring, in particular to a wired pipeline monitoring system. Background technique [0002] Thermal pipelines are a common form of pipelines. Due to the relatively high atmospheric pressure in the pipelines and the unpredictable environment around the pipelines, pipeline ruptures and leakages occur from time to time. The thermal pipeline is a lifeline project. Once damaged during operation, it will have a serious impact on heating and heat production, causing direct economic losses and adverse social impacts. For direct burial laying, because it is directly laid in the soil, if the pipeline leaks, it will easily cause heat loss in the pipeline network, large-scale damage to the pipeline, and ground settlement caused by ground water ingress. [0003] At present, the existing pipeline leakage monitoring technologies mainly include: manual detection method, optical fiber monitoring method and nega...
