Intelligent oil gas concentration monitoring system based on field bus network

Abstract

The invention discloses an intelligent oil gas concentration monitoring system based on a field bus network. The system is composed of a gas station oil tank area environment parameter acquisition platform based on a CAN field bus network and a gas station oil tank area environment multi-point oil gas concentration leakage classification subsystem. The system realizes intelligent detection of theoil gas leakage concentration of the gas station oil tank area environment and classification of the oil gas leakage concentration level. The system not only effectively solves many problems existingin the oil gas concentration detection of the gas station oil tank area environment caused by unreasonable design of the oil gas concentration detection equipment, backward equipment, incomplete detection system and the like of the traditional gas station oil tank area environment oil gas concentration detection device, but also effectively solves the problem that the existing gas station oil tankarea environment monitoring system detects and classifies the concentration of the gas station oil tank area environment, thereby greatly improving the accuracy and robustness of the oil gas concentration detection of the gas station oil tank area environment.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring of oil and gas environments at gas stations, in particular to an intelligent monitoring system for oil and gas concentration based on a field bus network. Background technique [0002] The environment of the oil tank area of ​​the gas station mainly stores oil storage containers or pipelines. If there is a leak, flammable liquid vapor will be generated. When the vapor pressure is high, there will be a danger of combustion and explosion, and the flammable liquid is fluid. At normal temperature, it will catch fire and burn if it encounters a fire source. If the storage container leaks, it will continuously evaporate flammable steam during the flowing process. Once it comes into contact with the fire source, even the tiniest spark will cause combustion. Therefore, strengthening fire safety management, real-time detection of oil and gas leakage concentrations that cause fires, eliminating...

Problems solved by technology

[0003] The invention provides an intelligent monitoring system for oil and gas concentration based on a field bus network. The invention not only effectively solves the problem of unreasonable design of oil and gas concentration detection equipment, backward equipment, and imperfect detection system of the traditional oil and gas concentration detection device in the oil tank area of ​​the gas station. The reason is that there are still many problems in the detection of oil and gas concentration in the oil tank area of ​​the gas station. According to the characteristics of the non-linearity of oil and gas concentration changes, large lag, and the large environmental area of ​​the oil tank area of ​​the gas station, the oil and gas concentration changes are complex, and the existing oil and gas concentration has been effectively solved. The environmental monitoring system of the oil tank area of ​​the gas station detects and classifies the concentration of the environment in the oil tank area of ​​the gas station, thereby greatly improving the accuracy and robustness of the detection of the concentration of oil and gas in the oil tank area of ​​the gas station
