Problems solved by technology

The problem with this method is: due to the limitation of temperature index measurement, the final judgment of whether there is a leak point is relatively vague, and it is difficult to obtain a more accurate conclusion; at the same time, the distance between two adjacent temperature sensors should not be too long , so it is necessary to set a large number of temperature sensors on the oil pipeline, which increases the monitoring cost and labor

Abstract

The invention discloses a monitoring system for a petroleum pipeline, which is characterized in that: the pipe wall of the petroleum pipeline is provided with a detection unit which comprises a pressure sensor and a flowmeter, both the pressure sensor and the flowmeter are connected with a signal acquisition amplifier which is connected with a PLC (programmable logic controller ), and an alarm is further connected with the PLC; and a plurality of the detection unit are arranged in an equidistance mode in the longitudinal direction of the petroleum pipeline. The monitoring system for the petroleum pipeline has the advantages of simple structure, ingenious design and operation convenience and is capable of accurately judging whether a leak source exists.

Description

technical field [0001] The invention relates to a supporting system of an oil pipeline, in particular to an oil pipeline monitoring system capable of monitoring whether the oil pipeline leaks in real time. Background technique [0002] In the process of oil transportation, the monitoring of oil pipelines is very important. It can detect whether there is leakage in the pipeline in time and remind the staff to carry out maintenance in time. If the monitoring of the pipeline is lost, once oil leakage occurs, it will not only bring economic loss, and more importantly, it will cause environmental pollution and endanger the health of residents around the transportation pipeline. The current monitoring method for oil pipelines is to install multiple temperature sensors along the length of the pipeline, and transmit the temperature change data of each monitoring point to the monitoring station, and judge whether there is a leak according to the temperature change. The problem with ...
