Gas station integrated data acquisition system

Abstract

The invention discloses a gas station integrated data acquisition system. The system comprises an oiling machine, a liquid level meter, a data acquisition module, a data acquisition gateway, a power supply and a server. The data acquisition module comprises an RS232 interface, a first power supply interface and a first LORA antenna interface which are fixedly installed outside; and a single-chip microcomputer and a peripheral circuit are fixedly installed at the bottom of the inner wall of the data acquisition module. The invention relates to the technical field of oiling machine data collection. The gas station integrated data acquisition system adopts a 32-bit single-chip microcomputer as product master control to ensure stability and performance of the data acquisition system; data is collected through LoRa network networking to ensure data transmission reliability and data transmission distance; through a high-performance 4G module, the communication reliability and stability are guaranteed; and the data acquisition module and an oiling machine monitoring microprocessor adopt RS232 serial ports, so that portability and anti-interference performance of data interaction are guaranteed.

Description

technical field [0001] The invention relates to the technical field of fuel dispenser data collection, in particular to an integrated data collection system for gas stations. Background technique [0002] The fuel dispenser is generally composed of a motor, an oil pump, an oil-gas separator, a flow measurement converter, a control valve, an encoder, a meter and control board, an indicating device, an oil sight device or an oil gun, etc. When refueling, just remove the oil gun For the refueling of the motor vehicle, the fuel tank control valve is closed and the refueling is completed. Refueling data such as refueling amount, amount, output tax or tax payable and other tax data are calculated at the same time and stored in the memory. The refueling data can be used to print invoices, and can also be used to print tax reports for tax declaration. During the use of the refueling machine, A data acquisition system is required to monitor the working conditions inside the tanker. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integrated data acquisition system for gas stations, which solves the problem that the existing fuel dispenser data stimulation system has poor stability, and the reliability of data transmission is low, and long-distance Data transmission, at the same time, the convenience and adaptability of the existing gas station integrated data acquisition system are poor, and it cannot resist the problem of external signal interference
