Comprehensive monitoring control system of gas station and monitoring control method thereof

Abstract

The invention relates to a comprehensive monitoring control system of a gas station and a monitoring control method thereof. An oiling machine is provided with a signal acquisition board, branches of an air-return pipeline are provided with gas flowmeters, the upper part of an oil tank is provided with a pressure sensor, a leakage sensor is arranged on the bottom of the oil tank and an oil conveying pipeline and under the oiling machine respectively, a power supply circuit of an oil-gas post-treatment device of the oil tank is provided with a current transformator, a main board of the oiling machine and the gas flowmeters are connected with the signal acquisition board, the signal acquisition board is connected with a monitoring controller, the pressure sensor, the leakage sensors and the current transformator are connected with the monitoring controller, and the monitoring controller is connected with an upper computer. The monitoring control method comprises the following steps that: 1) the signal acquisition board acquires oil-loading and air-return flow signals; 2) signals of the signal acquisition board, the leakage sensors, the current transformator and the air-return pressure sensor are input into the monitoring controller; and 3) the monitoring controller processes the signals, alarms, and outputs and uploads data. The comprehensive monitoring control system of the gas station and the monitoring control method thereof are suitable for comprehensive monitoring of the gas station, and have the advantages of accurate control as well as good environmental protection and safety guarantee performances.

Description

technical field [0001] The invention belongs to an auxiliary device of a gas station, in particular to a device for operating the gas station and monitoring and controlling environmental protection and safety. The device is a comprehensive monitoring system for gas station pollution discharge and pollution discharge control. The monitoring content is mainly the working status of the gas station oil and gas recovery system. At the same time, it can also monitor the gas station oil leakage, gas station pipeline and oil tank pressure, The working status of the oil and gas recovery post-processing device at the gas station, etc. Background technique [0002] The gas station pollution monitoring system is the latest field in the world. At present, only a few countries such as the United States have similar systems. For example, the similar product in the United States is a gas station liquid level meter, and the monitoring of the oil and gas recovery system belongs to its liquid ...

AI Technical Summary

Problems solved by technology

The main monitoring object of the device is the liquid level of the oil tank at the gas station, and at the same time, it also monitors the working status of the oil and gas recovery device; it cannot display the key indicators of the operation of the oil and gas recovery device in real time, and there is no dedicated collection device for the amount of oil paid by the tanker. This data must be Obtained from transaction data generated by fuel dispensers; monitoring devices without refueling station after-processing devices
