Abstract

The invention discloses a data acquisition and flow generation method for a liquid crystal screen of a refueling machine. The data acquisition and flow generation method comprises the following stepsof completing data acquisition of the liquid crystal screen of the refueling machine by embedded data acquisition equipment; judging starting and ending of a data signal in the acquisition data, and completing reading of the data signal; performing coding processing on the data signal, and converting the data signal to recognizable digit displayed by the display screen; generating transaction flownumbers; and packing the converted data signal and the transaction flow numbers, and transmitting the data signal and the transaction flow numbers to a network. The data acquisition and flow generation method has the advantage of high information processing efficiency and is convenient and flexible to update and maintain.

Description

technical field [0001] The invention relates to a refueling data processing technology, in particular to a method for collecting data on a liquid crystal screen of a refueling machine and generating flowing water. Background technique [0002] With the development of society, cars have become people's daily means of transportation, and refueling for cars has also become an indispensable part. Therefore, the gas station industry maintains the lifeline of the national economy. In order to compete for this position in an increasingly open market environment , it must not only have an advanced management level but also provide fast and high-quality services, and an advanced information management platform for a gas station not only marks the advanced management level of the petrochemical industry but also makes the service of the station effective Therefore, the collection of real-time information of gas stations has become an important means to master the import, sale and stora...
