Description

Oil supply device

The present invention relates to a refueling device for supplying fuel oil to an automobile at a refueling station.

The oil supply unit provided in the gas station is composed of a lower case in which oil supply mechanisms such as an oil supply pump and a flow meter are provided, and an upper case in which an oil supply amount indicator and an oil supply control device are provided.

A second case is provided on the first case, and each device is connected to the oil supply control device by a signal line, and each device is controlled by the oil supply control device so that oil supply is performed. Since there are a plurality of signal lines connecting each device and the oil supply control device, the connection of the signal lines is complicated, thereby increasing the manufacturing cost of the oil supply device.

In addition, the signal line is provided through a hole drilled in the upper case, through which the gasoline vapor penetrates, causing damage to the equipment in the upper case or sparking of the gasoline vapor intruded if the equipment causes sparks.

The present invention has been proposed in view of the above-described problems of the prior art, and it is possible to reduce manufacturing costs by eliminating the need for signal lines for connecting each device and the oil supply control device, and to eliminate the need for holes through which the signal lines pass. It is an object of the present invention to provide a lubrication device that prevents the gasoline vapor from invading, prevents damage to the device by the gasoline vapor, and eliminates the risk of ignition of the gasoline vapor by the spark of the device.

To this end, the present invention includes a lower case provided with an oil supply mechanism and an oil supply mechanism control device (such as an oil supply pump and a flow meter), and an upper case provided with an oil supply indicator and an oil supply control mechanism, the housing being formed by the upper case and the lower case. In the oil supply apparatus constituting the apparatus, the transceiver is connected to the oil supply mechanism control device provided in the lower case, and the transceiver is also connected to the oil supply control device provided in the upper case, so as to receive a signal in both transmission and reception periods. Lubrication is controlled.

According to the present invention having such a configuration, it is possible to receive various signals by radio. When the signal is transmitted by radio, the signal line connecting each device and the oil supply control device is unnecessary, and various costs (including manufacturing costs) related to the signal line arrangement can be reduced.

In this way, if the signal line is unnecessary, the hole through the signal line is also unnecessary, so that the inside of the housing can be sealed, so that there is no damage to the device due to gasoline vapor intrusion into the case. There is no risk.

In an embodiment of the present invention, it is preferable that a flag is applied to signals transmitted from both transmitters so that the signal is identified by the flag. By adopting such a configuration, no interference with signals can be prevented, and malfunctions and malfunctions can be prevented.

In addition, the antennas of both transceivers are provided to face each other, and the case in which the antennas face each other may be made of a material capable of signal transmission.

According to such a configuration, accurate reception of the signal can be achieved to prevent malfunction malfunction control.

Alternatively, the lower case and the upper case may be partitioned by a partition plate and an antenna so that either one of the two transceivers may be configured by the partition plate and an antenna.

According to such a structure, the partition plate (cum-antenna) can reduce manufacturing cost by the share of one transceiver.

In addition, the oil supply device of the present invention comprises a casing of the oil supply device by the upper case and the lower case, the lower case is provided with an oil supply mechanism and the oil supply mechanism control device, the upper case is provided with a fuel supply indicator and display control device In addition, a separate case provided with a lubrication control device is provided outside the lubrication device, is provided in the lower case, and connects the transceiver to the lubrication device control device, and connects the transceiver to the display control device provided in the upper case. And a transceiver is connected to the oil supply control device provided in the separation case so as to receive a signal in each transmission / reception period so that the oil supply is controlled.

With this configuration, it is possible to transmit and receive signals by radio, and when the radio is transmitted and received, the signal line connecting each device and the oil supply control device is unnecessary. Therefore, the manufacturing cost can be reduced by reducing the cost required for the excretion of signal lines.

In the case of receiving a signal by radio, a hole for penetrating the signal line in the case is unnecessary, so that the case can be sealed, so that the device is not damaged due to gasoline vapor intrusion into the case. There is no risk of flammability of the gasoline vapor by the spark of the device.

Here, it is preferable that the signal is identified by the flag and the identification number by adding a flag and an identification number to the signals transmitted from each transceiver.

Such a configuration prevents the misunderstanding of a signal and the miscontrol accompanying it. Therefore, the oil supply mechanism control device and the display control device in the plurality of oil supply devices can be controlled by one oil supply control device (equipped in a single separate case).

In addition to this, as compared with the case where an oil supply control device is provided for each oil supply device, various costs can be lowered by using the oil supply control device as well.

When the signal is transmitted and received wirelessly, radio waves, light, electromagnetic waves, magnetism, and the like can be used as the signal transmission medium. In other words, radio signals, optical signals, electromagnetic signals, magnetic signals, and other signals are used as the transmitted signals.

In connection with this, it is also possible to make various settings regarding oil supply by the signal transmitted from a mobile telephone etc. In this case, the settlement of the charge may be performed at the time of automatic transfer of the telephone charge, for example.
