Description

  The present invention relates to a fueling device that is installed at a fueling station, and particularly relates to a fueling device that can improve maintainability.

  The fueling device installed in the gas station is provided with a control device that controls the operation of the motor that drives the pump and the operation of integrating the flow rate signal from the pulse transmitter of the flow meter and displaying it on the display. Yes. At the same time, the control device cumulatively stores error codes corresponding to the error contents when the connection status of each part, flow signal error, motor operation abnormality, etc. occur, and the error codes are operated in order of occurrence by operating the keyboard. The information is displayed on a sequential display or printed by a POS printer and used as maintenance information for inspection and repair.

  However, the method of displaying and printing the error code on the spot relies on the memory of the gas station workers to identify the type of operation and situation in which the error occurred. It was difficult to obtain information, and proper treatment was not always possible.

  As a result, the response to inspections and repairs may be delayed, which may hinder the operation of the gas station that is the customer, lose the customer's trust, and make many sacrifices in time and money.

There is a technique (Patent Document 1) that displays abnormal data in a device that is placed on a loading platform such as an automobile and performs metered refueling such as kerosene. It is related to the device and outputs an error signal by checking the refueling operation based on the flow rate signal. It does not conform to the refueling device installed at the filling station, and the error is promptly related to the refueling operation. It is impossible to grasp and repair. In addition, there is a technology related to a monitoring device such as operation of a control panel in nuclear power generation (Patent Document 2). Although this technology is effective, it is related to nuclear power generation, etc. It is to be monitored, and an error of the fueling device installed in the gas station cannot be detected.

  In order to refuel an automobile, a customer's card is read by a card reader 24, refueling data such as a refueling amount is input from a keyboard 23, a refueling nozzle 14 is removed from a nozzle hook 15, and an ON signal is transmitted from a nozzle switch 16. When the value is input to 26, the oil supply control unit 32 of the control device 26 returns the previous oil supply amount displayed on the oil supply amount indicator 21 to zero. Then, the refueling nozzle 14 is inserted into the fuel tank of the automobile, and if the determination of the oil type sensor 31 provided in the refueling nozzle 14 is the oil type OK, the refueling motor 11 is activated to drive the pump 9. When the valve of the oil supply nozzle 14 is opened, oil supply is started, and the flow rate signals input from the pulse transmitter 12 of the flow meter 10 are integrated and displayed on the oil supply amount display 21. When the fuel tank is full, the valve of the fueling nozzle 14 is closed and the fueling is finished. When the fueling nozzle 14 is hooked on the nozzle hook 15 and an off signal is input from the nozzle switch 16 to the control device 26, the fueling motor 11 is turned off. Thus, the drive of the pump 9 is stopped.

  Although the oil type sensor 31 determines that the oil type is different, if it is confirmed that the oil type is erroneously detected, the oil supply is performed if the oil type detection release switch 27 is pressed. In addition, when a mistake is made in the refueling operation and a danger is felt, the refueling operation is stopped by pressing the emergency stop switch 28.
