Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an improvement in a refueling device such as a suspended refueling device.

[Prior art]

Generally, this type of suspended oil supply system includes a pipe whose one end is connected to a tank and whose other end opens at a high point in the structure, a pump installed in the middle of the pipe and driven by a pump motor, and a flow meter. , a hose lifting device installed at a high place of the structure and connected to the other end of the piping, a hose suspended from the hose lifting device so as to be able to rise and fall, and a refueling nozzle provided at the tip of the hose. , a switch box with a built-in one-hand lift switch installed in the middle of the hose at or near the refueling nozzle, an indicator installed on the structure and located in a place easily visible to the customer, the pump motor, the flow meter, and the hose. It consists of a lifting device, a hand-held lift switch, and a fuel supply control circuit connected to a display.In conjunction with the operation of the hand-held lift switch, the oil supply nozzle is raised and lowered, and the pump motor is operated to pump oil by opening and closing the oil supply nozzle. It is now possible to refuel.

At regular gas stations, regular gasoline,
To refuel with high octane gasoline, diesel oil, etc., 3 to 5
It is equipped with a suspended weighing machine that guides vehicles according to the type of oil to be refueled and refuels at the required location.

For this reason, a large number of indicators that display the amount of fuel to be filled are installed on the walls of the fuel station structure for each suspended weighing machine, making it difficult for customers to know which indicator is fueling their car. Sometimes you don't know.

To this end, the hose lifting device, refueling nozzle, indicator, etc. are color-coded by oil type, the hose lifting device and indicator are numbered, and the indicator is equipped with a flashlight to indicate when refueling is in progress. Countermeasures such as flashing are being adopted. However, all of these measures are based on the premise that the display can be seen visually, and if a large vehicle is parked in front, the display will not be visible, and the oil type, oil type, etc. will be checked only after refueling is complete. The reality is that the amount of oil to be supplied is known, which can lead to doubts about whether the desired type of oil is being supplied correctly.

In order to improve these shortcomings, audio notification devices such as speakers that notify the type of oil and amount of oil to be supplied are installed on the hose lifting device and the wall of the structure for each suspended weighing machine. There is a known system configured to notify the user of the greeting and the type of oil, and to notify the amount of refueling and the greeting at the end of the process. By providing the audio notification device in this manner, the type of oil and amount of oil to be supplied can be known as audio information, which is convenient even when the display is not visible.

[Problem that the invention seeks to solve]

However, since the audio notification device according to the prior art is provided corresponding to each suspended weighing machine, the audio information and melody are independently uttered regardless of the status of the other weighing machines.

As a result, when multiple weighing machines operate simultaneously or in parallel to refuel, not only is it noisy, but it may also be difficult to distinguish which weighing machine is reporting what. The problem is that customers may misunderstand.

Furthermore, since the audio notification device is installed on a wall of a hose lifting device or a structure that is far from the refueling work position, there is a problem that it is difficult to hear due to surrounding noise, etc., and information cannot be accurately transmitted.

The present invention has been made in view of the problems of the prior art, and provides an audio notification device for each weighing machine located at the refueling work place so that refueling information can be reliably heard. It is an object of the present invention to provide a refueling device which improves the reliability of refueling work.

[Means for solving problems]

It has a function of displaying the refueling amount as the amount of refueling, and a function of outputting an audio control signal to the audio circuit 30 in accordance with the refueling work status. The audio circuit 30 is composed of a voice synthesis circuit, a voice storage circuit that stores voice phrases, numerical values, etc., and a melody storage circuit provided as necessary, and is driven and controlled by the voice control signal from the refueling control circuit 29. ,
A required audio signal is outputted to a local speaker 19 near the refueling nozzle 14 via a switching circuit 31 and an amplifier 21, so that refueling information is announced by audio. moreover,
The switching circuit 31 outputs an audio signal only to the local speaker 19 when each of the talk switches 20 and 34 is in the open state, and when the local talk switch 20 is pressed, cuts off the audio circuit 30 and turns off the microphone. The audio information from the handheld speaker 19, which also serves as a speaker, is output to the office speaker 33 to allow the sound to be produced, and conversely, when the talk switch 34 in the office is pressed, the audio information is output to the office speaker 33.
0, and outputs audio information from the office speaker 33, which also serves as a microphone, to the local speaker 19, allowing it to produce audio.

Although the present embodiment is configured as described above, it is assumed that the vehicle 36 is refueled using one of the three weighing machines, for example, a system including the refueling nozzle 14A.

Now, when the lowering switch 17A is operated to lower the refueling nozzle 14A from the standby position (B) to the refueling position (C), the lifting motor IOA is activated under the control of the refueling control circuit 29A.
rotates downward, the refueling nozzle 14A descends, and the pump motor 5A starts. At this time, the refueling control circuit 29A outputs an audio control signal to the audio circuit 30A, and
The greeting to start refueling and the type of fuel are generated as an audio signal, for example, ``Welcome, I'm refueling with regular gasoline now.0 The display number is 1.'' As a result, the above-mentioned audio information is uttered from the local speaker 19A, and is notified to the worker and the driver of the vehicle 36. At this time, since the handheld speaker 19A is provided near the refueling nozzle 14A, the operator and driver can clearly hear the type of liquid and the display number.

Next, when the refueling nozzle 14A is lowered to the refueling position (c), the operator inserts the refueling nozzle 14A into the fuel tank of the vehicle 36 and opens the valve. As a result, the regular gasoline in the underground tank 4A is transferred to the pipe 3A, the pump 6A, and the flow meter 7A.
, is discharged from the refueling nozzle 14A via the hose 13A, the flow rate at this time is measured by the flow meter 7A, the flow rate pulses are counted by the refueling control circuit 29A, and displayed as the refueling amount on the display 27A. During this time, use a handheld speaker if necessary!
The melody may be played starting from 9A.

Furthermore, when refueling progresses and a predetermined amount of refueling is completed, the refueling nozzle 14A is closed and the fuel is removed from the fuel tank. Then, if the lift switch 18A is pressed, the lift motor I
The OA rotates upward, and the refueling nozzle 14A returns to the standby position (
b).

At this time, an audio control signal is output from the refueling control circuit 29A to the audio circuit 30A, and the audio circuit 30A greets you at the end of refueling and indicates the amount of refueling, for example, "Thank you, the current amount of refueling is 11 L!" generated as an audio signal,
The above audio information is uttered from the handheld speaker 19A. This allows the driver to know that the refueling amount is tti, and even if the display 27A is not visible due to other vehicles 37, the customer will not feel distrustful.

On the other hand, if, for example, an emergency occurs and you want to contact the office at the refueling work position, switch port,
By pressing the talk button 25A attached to the speaker 5A, the speaker 19A operates as a microphone. As a result, when a worker says to the local speaker 19A, for example, "The refueling nozzle has broken. Please cut off the optical power supply urgently," the office speaker 33A can hear this audio information. . Additionally, if you wish to contact the work site from the office, please
Press the talk switch 34A to turn on the office speaker 33A.
For example, one source of power was cut off. '', this audio information can be heard through the local speaker 19A.

In addition, although the above description described the case where the refueling nozzle 14A was used, the refueling nozzle 14B.

The same applies to the case of refueling using 14c.

The embodiment of the present invention has been described above as having independent weighing machines consisting of three systems, but there is one weighing machine.
There may be only one group, or four or more groups. In addition, each metering device is not limited to an independent lubrication system, but can be branched from the outlet side of one pump to multiple flowmeters, hoses, and lubrication nozzles, or from the outlet side of one flowmeter to multiple hoses and lubrication nozzles. The refueling system of the present invention may be configured to branch, and the refueling system of the present invention is not limited to a suspended refueling system, but may be applied to a refueling vehicle as shown in Japanese Patent Application No. 61-90985 previously filed by the present applicant. . Furthermore, the voice information that is emitted from the first hand speaker is not limited to the one in the example, but includes various information such as "Auto stop has worked.", "Refueling nozzle has been closed.", "Please check the display." The refueling status and messages may be notified.

〔Effect of the invention〕

The oil supply device according to the present invention has been described in detail above, and has the following effects.

- By providing an audio notification device at the refueling nozzle or in the middle of the hose near it, the refueling information necessary for refueling can be reliably heard in the ears of workers and customers.

■ Even if multiple weighing machines start refueling at the same time or in parallel, II! Since it is easy to distinguish, the volume is low, and a small audio notification device is required, it does not become a source of noise at gas stations.

■ The voice notification device is installed in the switch box at hand, so it can receive refueling information specific to the weighing machine, i.e., the type of liquid,
The display number, etc. can be notified before refueling work, which helps workers prevent the wrong type of liquid from being refueled, and allows customers to confirm the type of liquid and know the display number in advance. , can increase trust.

(2) Since the voice notification device is placed using the space inside the switch box that serves as the operating section at hand, extra installation space is not required and the device has excellent operability.
