Gas station tax evasion prevention system and method

Abstract

The invention belongs to the technical field of gas station tax monitoring, and particularly discloses a gas station tax evasion prevention system which comprises a mainboard and at least one CPU located on the mainboard. The gas station tax evasion prevention system further comprises a power supply module, a debugging interface, a parameter acquisition assembly, a cloud platform and a clock module which are respectively connected with the CPU. The debugging interface is used for debugging parameter setting log output; the clock module provides time information; the parameter acquisition assembly at least comprises an oil quantity encoder, a liquid level sensor and a tax declaration port; the oil quantity encoder, the liquid level sensor and the tax declaration port are respectively connected with the CPU; the oil quantity encoder is used for converting the oil outlet quantity into a pulse signal and sending the pulse signal to the CPU; the liquid level sensor is used for measuring oil tank liquid level parameters; and the tax declaration port is used for reading refueling data of a refueling machine in real time. By means of the gas station tax evasion prevention system, the oil outlet quantity and the oil inlet quantity of a gas station are checked according to the data detected by the tax declaration port, the oil quantity encoder, a liquid level instrument, the liquid level sensor and the like, the sales quantity of product oil is ensured, and the accuracy of tax data is ensured.

Description

technical field [0001] The invention belongs to the technical field of gas station tax monitoring, and in particular relates to a gas station tax evasion prevention system and method. Background technique [0002] With the development of the transportation industry, due to the interest-driven growth of refined oil sales, the lack of relevant regulations and policies of the supervisory department and the backwardness of management technology, the statistics and supervision of refined oil circulation data are limited and the management is insufficient. Many gas stations have imperfect financial systems, which makes it impossible to accurately grasp the sales volume and amount of refined oil, and affects the statistical analysis of refined oil circulation data in the region. [0003] In the existing technology, by introducing the concept of tax cloud management and using "Internet of Things +" technical means to ensure the authenticity and reliability of sales data, thereby str...
