Detection, analysis and early warning method of oil and gas concentration in gas station

Abstract

The invention relates to comprehensive monitoring of safe operation of refueling stations, in particular to an oil-gas concentration detecting device for the refueling stations and an analyzing and early warning method thereof. The oil-gas concentration detecting device is simple in structure, can detect in real time and can give out early warning. The device comprises an oil-gas concentration sensor, a programmable logic controller, an operation display module, a power circuit breaker control module and an alarm, wherein the oil-gas concentration sensor can detect an oil-gas concentration value of an installed point in real time; the programmable logic controller can perform comprehensive calculation and three levels of judgment; when a first level and a second level are exceeded, corresponding alarm prompt is given and a touch screen flashes to give prompt; when a third level is exceeded, whether a power of the oil refueling station is at a switch-on position is quickly detected; if the power is at the switch-on position, the power is quickly tripped, third-level alarm sound is given, and the touch screen flashes to give prompt; after real-time detection and judgment are finished, data are stored, recorded and communicated for historic record and check to use; a procedure returns to the oil-gas detecting and judging step to proceed continuously to achieve real-time detection and early warning of oil-gas concentration.

Description

technical field [0001] The invention relates to comprehensive monitoring of safe operation of refueling and gas stations, in particular to a method for detection, analysis and early warning of oil and gas concentration in a refueling and gas station with simple structure, monitoring and alarming for comprehensive analysis and determination of oil and gas concentration, and cutting off power supply. Background technique [0002] Existing oil and gas concentration detection at refueling stations generally uses oil and gas sensor devices to detect and alarm, but this detection method is only judged by the detected instantaneous threshold value, and does not intelligently infer the development process of oil and gas concentration, resulting in excessive When the value is high, the concentration is too high due to the aggregation effect of the concentration, and the alarm time is delayed. Contents of the invention [0003] The purpose of the present invention is to overcome the...
