Problems solved by technology

[0002] At present, due to the fact that the gas (oil) machine manufacturers do not disclose their computer data interface functions, software developers cannot obtain display data, and some data obtained by intercepting pulse signals from the front end have large errors and accuracy. It is difficult to achieve 100%, and a complete set of intelligent solutions cannot be formed, so it is difficult to promote
The software developed by the manufacturer can only be aimed at the gas (oil) machine produced by the factory, and cannot meet the needs of Tongka

Embodiment Construction

[0009] Step 1: ①. Connect the seven-segment code solder joints of the data display behind the LED display with wires, and connect the current signals displayed by the seven-segment code to the acquisition card and input them into the computer. ②. Use the line to connect the working status signal of the gas (oil) machine to the computer through the acquisition card. ③. Connect the switch signal of the gas (oil) machine to the acquisition card and the computer through the relay with the circuit.

[0010] Step 2: After the computer program starts to serve, it will detect the authentication card and check whether the card reader is in the open state. When the test is passed, the computer program first receives the signal from the card reader, and then the program judges the current signal to determine whether it is allowed to open The working status of the gas (oil) machine.

[0011] Step 3: The computer program judges whether the currently displayed data is gas (oil) data by det...

Abstract

Display data of an LED display screen is accurately obtained by combination of computer softwares and a data collection card. Whether a gas(fuel) charger is allowed to be started and stopped is controlled based on different states. Thereby a problem that a data collection common interface and automatic control of different gas(fuel) chargers is effectively solved, errors and embezzlement phenomena due to anthropogenic factors generated in a manual circumstance are eliminated, labour intensity is reduced, and request of department for production and management is satisfied.

Description

Field of invention: [0001] The invention relates to an IC card intelligent charging technology for a gas (oil) station by combining computer software technology and a collection card. Background technique: [0002] At present, due to the fact that the gas (oil) machine manufacturers do not disclose their computer data interface functions, software developers cannot obtain display data, and some data obtained by intercepting pulse signals from the front end have large errors and accuracy. It is difficult to achieve 100%, and a complete set of intelligent solutions cannot be formed, so it is difficult to promote. The software developed by the manufacturer can only be aimed at the gas (oil) machine produced by the factory, and cannot adapt to the needs of Tongka. Invention content: [0003] The computer program first collects the high and low level signals from the LED display data through the acquisition card, and then restores them to corresponding numbers in the form of s...
