Monitoring and early warning system and method for petrochemical product conveying pipeline leakage

Abstract

The invention discloses a monitoring and early warning system and method for petrochemical product conveying pipeline leakage. The monitoring and early warning system comprises a sensing detection unit, a wireless communication unit, a remote terminal processing unit, a power supply unit and an execution mechanism. The monitoring and early warning method comprises the following steps of acquiringdata of temperature, humidity, illumination, carbon dioxide, and vibration as well as data of target gas concentration and target product leakage as an original data set; training by adopting a grey neural network algorithm, taking the original data to time integral as input data of the algorithm, and establishing a mathematical relationship model; collecting real-time monitoring data, performingreal-time display output and storage on a remote terminal, and predicting leakage of a target product and leakage occurrence probability according to the mathematical relationship model; and correspondingly starting leakage early warning according to the leakage occurrence probabilities. The system and the method have the characteristics such as good universality, high accuracy, and low energy consumption, and are suitable for leakage monitoring and early warning in a long-distance chemical pipeline conveying process.

Description

technical field [0001] The invention relates to the field of monitoring and early warning, and more specifically relates to a petrochemical product delivery pipeline leakage monitoring and early warning system and method for realizing real-time monitoring and early warning of petrochemical product delivery pipeline leakage. [0002] technical background [0003] In the petrochemical industry, pipeline transportation, as the main transportation method of petrochemical products, greatly saves the transportation cost of petrochemical products and improves the safety and reliability of transportation. Severe corrosion, cracks, and loose joints usually occur in some nodes of the pipeline, including joints, welds, fulcrums, etc., which cause pipeline leakage. After the pipeline leaks, the high-pressure oil and gas in the pipeline will enter the air, causing economic losses and environmental pollution, and even explosions, toxic substances volatilization and other safety accidents, ...

Problems solved by technology

In April 2014, the leakage of PetroChina’s petrochemical pipeline caused benzene in Lanzhou’s tap water to exceed the standard by 20 times, making the safety of local drinking water unsafe and causing serious panic among citizens

The above external detection method is limited by the accuracy of the instrument, it is difficult to detect small leaks, it cannot be accurately located and has poor versatility
