Japanese Patent Application Laid-Open No. 2010-228795 discloses a technique for suppressing the consumption of the battery built in the hand counter by monitoring the state of the fueling device and changing the reception cycle according to the state.

The invention of Japanese Patent Laid-Open No. 2010-228796 monitors the state of the fueling device and changes the reception cycle according to the state, thereby suppressing the consumption of the battery built in the hand counter. In the prior invention, when the hand counter cannot receive the current fuel amount from the fueling device, the current fuel amount is estimated and displayed based on the change in the past (most recent) fuel amount.

Japanese Patent Application Laid-Open No. 2008-018965 discloses a technique for charging a battery built in a hand counter in a contactless manner.

In the prior art, the state of the fueling device is monitored and the power consumption is suppressed by changing the reception cycle according to the state. However, in the case of wireless, the power consumption is large and the battery is consumed, so the battery is frequently replaced. There is a need. In addition, other prior art discloses a method for charging a battery in a non-contact manner, but a secondary battery cannot be used permanently and must be replaced. When recognizing that the battery has run out when refueling, the battery will be replaced at that time, resulting in a loss in refueling.

When the hand counter cannot receive the oil amount from the weighing machine, the current oil amount can be estimated and displayed based on the change in the past oil amount, but the display of the hand counter and the weighing machine must be the same. There is no guarantee.

On the other hand, wireless communication cannot always be performed normally due to obstacles or disturbances. If communication is interrupted during refueling and the latest refueling data cannot be received, the old refueling data will remain displayed, causing a situation where the contents displayed on the hand counter and the weighing machine are different, resulting in doubt about the refueling data. End up.

  An object of the present invention is to provide a control method in an oil supply apparatus that increases the reliability of an indicator provided in a nozzle and does not cause a loss in oil supply.

The method of the present invention comprises a meter having a first indicator for displaying refueling information including a current refueling amount and a refueling amount during refueling;
A nozzle connected to the weighing machine via a hose;
A control method in a fueling device provided with a second indicator for displaying the fueling information provided on the nozzle and wirelessly transmitted and received from the weighing machine,
Wirelessly transmitting the refueling information from the weighing machine to the second indicator every first predetermined time during refueling;
Repetitively determining whether or not the transmitted refueling information is received within a second predetermined time;
The second indicator displaying the refueling information when the refueling information is received within the second predetermined time;
And a step of notifying the malfunction when the refueling information is not received within a second predetermined time.

By displaying that the wireless communication state is poor on the second display of the nozzle, it is possible to prevent the display content of the weighing machine from being inconsistent. Thereby, when the communication is not normal, the customer who is refueling pays attention to the display of the weighing machine, so that there is no possibility that the refueling data is doubted.

Repeatedly monitoring the voltage value and / or current value supplied to the second indicator during the refueling every third predetermined time;
As a result of the monitoring, when the voltage value and / or current value is equal to or lower than a predetermined threshold value, a step of displaying a battery exhaustion on the second display is provided.
By displaying that the battery is low on the second indicator, the battery can be replaced with a margin when the fueling device is not in use, so that there is no possibility of hindering the fueling operation.

  In the present invention, the second indicator may notify the problem by not displaying the refueling information, or the second indicator may indicate the error by performing an error display. Or you may alert | report a malfunction by both said.
