2. Description of the Related Art In a fuel refueling device of this type, fuel oil is purified to a predetermined refueling pressure and refueling through a refueling device such as a pressure control valve, a filter, a flow meter, and a venturi provided in a refueling pipe. The aircraft is refueled according to the flow velocity and the amount of refueling. Conventionally, such a fuel refueling device such as a servicer or a fuel refueling car generally has a substantially mechanical structure, and includes the pressure on the inlet side, the outlet side, the venturi side of the refueling pipe, and the refueling flow rate (instantaneous The flow rate) and the amount of refueling (total amount of refueling), etc. were all displayed in analog form at the location of the refueling piping, refueling equipment, etc. for reading and monitoring. Further, all the pressure control valves and other control valves have been manually operated at that location to adjust the predetermined oil supply pressure, oil supply flow rate, oil supply amount, and the like.

[0003]

By the way, the following problems have been pointed out in such a conventional fuel supply system. First of all, information such as pressure of each part, refueling flow velocity, refueling amount, etc. is read and monitored at a place distant from the location of the refueling piping, refueling equipment, etc., such as a cab, a refueling workbench, or a nearby ground. It was difficult to do. Secondly, similarly, it is difficult to remotely operate the pressure control valve and other control valves at a place distant from the location, and it has been difficult to control the refueling pressure, the refueling flow velocity, the refueling amount, and the like. Thirdly, especially when an abnormality occurs in the pressure value, the oil supply flow rate, the oil supply amount, etc. of each part, the pressure control valve and other control valves cannot be immediately closed, and the oil supply often cannot be stopped in time. Therefore, these first, second, and third problems have been pointed out to the accuracy and safety of the refueling work for the aircraft.

In view of the above situation, the present invention has been made to solve the problems of the above-mentioned conventional example, in which the control means is based on the signals from each pressure sensor, flow meter, etc. In addition to outputting predetermined information to the pressure control valve and the flow rate control valve as appropriate, the control means further provides predetermined manual lubrication according to claim 1.

A pressure sensor that is attached and detects each pressure, a detection signal of each pressure sensor and a pulse signal from the flowmeter are input, and based on these, the pressure value of each part, the instantaneous flow rate, the integrated amount of lubrication, etc. are calculated. And outputs the information to the information display section, and determines whether or not these are normal, and if they are not normal, a control means for outputting a close signal to the pressure control valve and the flow control valve. I will do it.

Further, in claim 1, the control means is
In addition, manual refueling control is possible. Next, in claim 2, the control means can control preset refueling. Further, in claim 3, the control means can select control of manual refueling or preset refueling.

That is, in the control means of claims 1 and 3, in the case of manual refueling, a signal from an opening / closing switch attached to the flow control valve is input, and based on this, the above information display. To the pressure control valve and the flow rate control valve based on the signal from the stop key attached to the flow rate control valve. . Further, in the control means of claims 2 and 3, in the case of preset refueling, a preset amount is input, and based on this, an appropriate opening / closing signal is output to the pressure control valve and the flow rate control valve, and The opening information corresponding to the preset amount is output to the information display unit, and the opening signal is output to the flow control valve.

[0008]

Since the present invention comprises such means, it operates as follows. In refueling, in this fuel refueling device, the control means controls the pressure value of each part, the instantaneous flow rate, and refueling based on the detection signals from the pressure sensors on the inlet side, the outlet side of the refueling pipe, the venturi, etc. and the pulse signals from the flowmeter. The integrated amount and the like are calculated and output to the information display unit, and when these are not normal, a closing signal is output to the pressure control valve and the flow rate control valve. Further, in claim 1, manual lubrication, in claim 2, preset lubrication, and in claim 3, both of them are selectively possible. In the case of manual refueling, the control means, based on the signal from the open / closed degree switch,
The opening information is output to the information display unit, the opening signal is output to the flow control valve, and the closing signal is output to the pressure control valve and the flow control valve based on the signal from the stop key. In the case of preset refueling, the control means outputs an opening / closing signal to the pressure control valve and the flow rate control valve as appropriate, and outputs the opening degree information to the information display section as well as the opening degree signal to the flow rate control valve.

Therefore, firstly, the pressure value of each part, the instantaneous flow rate,

To optimize the fuel oil pressure adjustment. As described above, in the illustrated example, the pressure control valve 10 and the flow rate control valve 13 are opened / closed by the opening / closing means using air pressure, but of course, the invention is not limited to this, and for example, an explosion-proof structure is used. The adoption of electric type opening / closing means is also conceivable.

Next, the central controller C and the controller R
I will describe. The central controller C has a microcomputer MC, which is a control means of the servicer 1, built therein. As is well known, the microcomputer MC is a CP.
It consists of U, ROM, RAM, CLOCK, etc. And
This microcomputer MC, which is a control means, has a configuration shown in FIG.
As shown in the above, each pressure sensor S1, S2, S3, S
4, the detection signal from S5 and the pulse signal from the flowmeter 12 are input. Further, the microcomputer MC includes a power switch 25, a reset key 26, a start switch 27, a stop key 28, a keyboard 29, a deadman switch 30, and an opening / closing degree switch 31 of the flow control valve 13.
Signals from etc. are input. Further, a control signal is output from the microcomputer MC to the pressure control valve 10, the flow rate control valve 13, the information display section 32, the display lamp 33 group, the buzzer 34, the slip issuing machine 35, and the like.

The central controller C incorporating such a microcomputer MC is, for example, the cab 36 of the servicer 1.
As shown in FIG. 3, the power switch 25, the reset key 26, the display lamp 33 for various errors, and the changeover switch 37 for the two controllers R, for example, are arranged. Next, in the illustrated example, the controller R is connected to the central controller C via an optical fiber cable 38, and two controllers R are provided for the refueling workbench 7 side and the ground side. The controller R has a start switch 27 and a stop key 28 as shown in FIG.
In addition, an opening / closing switch 31 for setting the opening / closing degree of the flow control valve 13 in the case of manual refueling, a keyboard 29 for setting a preset amount in the case of preset refueling, an emergency deadman switch 30 and the like are provided. The deadman switch 30 forms a grip portion of the controller R and is normally off during refueling, but it is turned on when a worker releases his hand during refueling, and is normally installed on the air pipe 20 described above. The open deadman valve 22 is closed, and in an emergency, therefore, the pressure control valve 10 is closed to function as an emergency stop of refueling. Further controller R
Is provided with a group of display lamps 33 and an information display unit 32. The group of display lamps 33 displays that the power switch 25 is turned on, the deadman switch 30 is turned on, various errors, etc., and the information display unit 32 is used for preset refueling. In this case, the preset amount, the pressure value of each part, the instantaneous flow rate, the information of the integrated amount of oil supply, the opening degree information of the flow rate control valve 13, and the like are displayed as images.

In the microcomputer MC which is the control means of the central controller C, the detection signals from the pressure sensors S1, S2, S3, S4 and S5 and the pulse signal from the flowmeter 12 are input in this way. Based on these, the pressure value of each part, the instantaneous flow rate, the integrated amount of refueling, etc. are calculated, and these information is output to the information display section 32 of the controller R, and it is judged whether these are normal or not. In this case, a closing signal is output to the pressure control valve 10 and the flow rate control valve 13. Further, in the microcomputer MC which is the illustrated control means, it is further possible to select manual refueling or preset refueling. First, in the case of manual refueling, based on a signal from the opening / closing degree switch 31 for the flow rate control valve 13 provided in the controller R, the opening degree information is output to the information display section 32 of the controller R and the flow rate control is performed. An opening signal is output to the valve 13, and based on a signal from the stop key 28 of the controller R, a closing signal is output to the pressure control valve 10 and the flow rate control valve 13. On the other hand, in the case of preset refueling, the preset amount is input through the keyboard 28 of the controller R, and based on this, an appropriate opening / closing signal is output to the pressure control valve 10 and the flow rate control valve 13, and information of the controller R is output. The opening information corresponding to the preset amount is output to the display unit 32, and the opening signal is output to the flow rate control valve 13.

The present invention has been described above. Then it becomes as follows. 5, 6 and 7 are flowcharts of the control of this embodiment. FIG. 5 shows a basic control, FIG. 6 shows a manual refueling routine, and FIG. 7 shows a preset refueling routine. The operation of the embodiment will be described below with reference to these drawings.

A servicer 1 which is an example of this fuel refueling device.
Then, the pressure control valve 10 of the oil supply pipe 6, the filter 11,
Fuel oil is purified through a refueling device 5, such as a flow meter 12 with a pulse transmitter, a flow control valve 13, and a venturi 14, and is refueled to an aircraft at a predetermined refueling pressure, refueling flow velocity, and refueling amount. In addition, in the servicer 1, at the time of such refueling, the pressure sensors S1, S2 attached to the inlet 15 side, the outlet 17 side of the refueling pipe 6, the venturi 14, the air tank 19 of the air pipe 20, the air regulator 21, and the like.
Based on the detection signals from S3, S4, S5 and the pulse signal from the flow meter 12, the microcomputer MC, which is the control means of the central controller C, calculates the pressure value of each part, the instantaneous flow rate, the integrated amount of lubrication, etc. , And outputs these information to the information display section 32 of the controller R, and determines whether or not these are normal. If not normal, the pressure control valve 1
0, a close signal is output to the flow control valve 13. And further,
In the illustrated example, manual refueling and preset refueling are selectively enabled by the microcomputer MC as the control means.

These will be described in detail with reference to the flowchart. First, in step 1 of FIG. 5, the power switch 25
When it is determined that the ON state is ON, the routine proceeds to step 2, where the fully closed signal is output to the pressure control valve 10, and the step 3
Then, a fully closed signal is output to the flow control valve 13. Then, next, in step 4, the preset amount, the instantaneous flow rate, and the refueling integrated amount are set to 0, and in step 5, the information display section 32 of the controller R displays the image of the selection of the manual refueling or the preset refueling. . Note that this selection is performed, for example, by a selection switch (not shown) attached to the controller R, and the image display method on the information display unit 32 is, for example, no display in the case of manual refueling and preset in the case of preset refueling. This is done by displaying the quantity portion. Next, the flow proceeds to step 6, where it is determined whether or not manual refueling is performed, that is, whether it is manual refueling or preset refueling. If manual refueling, proceed to step 7; Proceed to 8. The routines for manual lubrication and preset lubrication will be described in detail later. And
When the manual refueling or the preset refueling is completed, the process proceeds to step 9, where it is determined whether or not the issuance of the slip is necessary. The control of the servicer 1 is generally performed in this way.

Next, details of the manual refueling will be described. In the case of manual refueling, the microcomputer MC, which is the control means, outputs the opening degree information to the information display section 32 of the controller R based on the signal from the opening / closing degree switch 31 for the flow rate control valve 13, and causes the flow rate control valve 13 to operate. An opening signal is output, and a closing signal is output to the pressure control valve 10 and the flow rate control valve 13 based on the signal from the stop key 28. These will be described with reference to the flowchart of FIG. 6. First, in step 11, an open signal is output to the pressure control valve 10, and then in step 12, the flow control valve 1
It is determined whether or not the opening / closing degree switch 31 for 3 is pressed, and if it is pressed, in the next step 13, an opening degree signal corresponding to the pressing of the opening / closing degree switch 31 is output to the flow control valve 13. It Thereafter, in step 14, the opening information of the flow rate control valve 13 is output to the information display unit 32 for image display, and in step 15, the pressure value of each part is A / D.
The converted data is output as information to the information display unit 32 and displayed as an image, and in the next step 16, it is determined whether or not the pressure value of each unit is normal. If normal, in the next step 17, the instantaneous flow rate and the refueling integrated amount obtained by counting the pulses from the flow meter 12 are output as information to the information display unit 32 and displayed as an image, and in the next step At 18, it is determined whether or not the instantaneous flow rate is normal. At this time, whether or not the pulse interval from the flow meter 12 is normal, that is, the smooth progress of the entire refueling that is the base of the refueling integrated amount, etc. is simultaneously performed. To be judged.

When it is determined in step 18 that the instantaneous flow rate is normal, in step 19, the stop key 2
It is determined whether or not 8 is pressed. If not, the process returns to step 12 described above, and this is repeated thereafter. When the stop key 28 is pressed in step 19, the process proceeds to the next steps 20 and 21, and the full closing signal is immediately output to the pressure control valve 10 and the flow rate control valve 13, and the refueling ends. If it is determined in step 16 that the pressure value of each part is not normal, and if it is determined in step 18 that the instantaneous flow rate is not normal, step 22
Then, the error display is performed on the display lamp 33 of the controller R or the like, and the process proceeds to steps 20 and 21, and the full closing signal is immediately output to the pressure control valve 10 and the flow rate control valve 13, and the refueling is stopped. It

Next, details of the preset refueling will be described. In the case of preset refueling, the microcomputer MC which is the control means, based on the input preset amount,
An opening / closing signal is appropriately output to the pressure control valve 10 and the flow rate control valve 13, and opening information corresponding to the preset amount is output to the information display unit 32, and an opening signal is output to the flow rate control valve 13. These will be described with reference to the flowchart of FIG. 7. First, in step 23, the preset amount is input by the keyboard 29 of the controller R, and
When the start switch 27 is pressed, the next step 2
In step 4, after the CPU of the microcomputer MC reads out the pre-scheduled information about the preset from the ROM, the process proceeds to step 25, and the open signal is output to the pressure control valve 10.

Then, in step 26, it is judged by counting the pulse from the flow meter 12 whether or not the planned amount, that is, the preset amount of fuel has been supplied. If not, in the next step 27, the stop key 28 is pressed. It is determined whether or not the button has been pressed. If not, the process proceeds to step 28, where the opening signal corresponding to the preset amount is output to the flow rate control valve 13 based on the information scheduled in the previous step 24, and in step 29, the information display unit 32 is displayed. The opening degree information of the flow control valve 13 is output and displayed as an image. Further, in step 30, the pressure value of each part is A / D converted and output as information to the information display part 32 for image display, and in step 31, it is determined whether or not the pressure value of each part is normal. . If it is normal, in the next step 32, the instantaneous flow rate and the refueling integrated amount obtained by counting the pulses from the flow meter 12 are output as information to the information display unit 32 and displayed as an image, and in step 33. It is determined whether or not the instantaneous flow rate is normal. At that time, it is also determined whether or not the pulse interval from the flow meter 12 is normal, that is, the smooth progress of the entire refueling that is the base of the refueling integrated amount and the like. To be done. Then, if it is determined to be normal in step 33, the flow returns to step 26 described above, and this is repeated thereafter.

If it is determined in step 26 that the preset amount of fuel has been completed, steps 34, 3
5, the fully closed signal is output to the pressure control valve 10 and the flow rate control valve 13, and the refueling is completed. When it is determined in step 31 that the pressure value of each part is not normal and when it is determined in step 33 that the instantaneous flow rate is not normal, the process proceeds to step 36, and the display lamp 33 of the controller R or the like is displayed. The error display is performed, and the process proceeds to steps 34 and 35 to immediately output a fully closed signal to the pressure control valve 10 and the flow rate control valve 13 to stop the fuel supply.

On the other hand, if it is determined in step 27 that the stop key 28 has been pressed, the flow proceeds to step 37, and a fully closed signal is output to the flow control valve 13 (regardless of this, pressure control is performed). A full-closed signal may be output to the valve 10). Next, in step 38, it is determined whether or not to change the preset amount. If the preset amount is changed, in step 39, the controller R of the controller R is changed. The preset amount is changed with the keyboard 29. Thereafter, in step 40, it is determined whether or not the start switch 27 has been pressed, and when it is pressed, the flow returns to step 28 described above. If the preset amount is not changed in step 38, the flow immediately proceeds to step 40.
Go to.

The control of the servicer 1 is performed in this way, and manual lubrication, preset lubrication, etc. are carried out. Now, in this servicer 1, the following 1st, 2nd, and 3rd are performed.

First of all, the pressure value of each part of the inlet 15 side, outlet 17 side of the refueling pipe 6, the venturi 14, the air tank 19, the air regulator 21, etc., the instantaneous flow rate, that is, the refueling flow velocity, the refueling integrated amount, that is, the refueling amount, And flow control valve 1
The information such as the opening degree of 3 is located away from the places such as the refueling pipe 6 and the refueling device 5 in the machine room 4 (for example, the refueling work table 7 or the ground)
An image is displayed on the information display section 32 of the controller R located at, and it is possible to read and monitor there (see FIG. 2 and the like). Secondly, the opening and closing of the pressure control valve 10 and the flow control valve 13 and the opening degree of the flow control valve 13 are similar to those of the central controller C and the controller which are located away from the places such as the oil supply pipe 6 and the oil supply equipment 5. The remote control is performed at R, and the microcomputer MC controls to a predetermined refueling pressure, refueling flow rate, and refueling amount. Then, manual refueling is performed by operating the open / close degree switch 31 for the flow control valve 13 and the stop key 28, and preset refueling is performed only by inputting a preset amount with the keyboard 29. Thirdly, and in particular, when an abnormality occurs in the pressure value, the refueling flow rate, the refueling amount, etc. of each part such as the inlet 15 side, the outlet 17 side of the refueling pipe 6, the venturi 14, etc., the microcomputer MC automatically And immediately, the pressure control valve 10 and the flow control valve 13
Is closed and refueling is stopped.

The present invention is not limited to the illustrated examples described above, and the following may be considered. First of all
In addition, in the illustrated example, it is possible to select manual refueling or preset refueling, but it is also possible to allow only manual refueling regardless of this. That is, the manual refueling can be controlled by the microcomputer MC as the control means (the preset refueling is not controlled). In the case of the manual refueling, as in the case described above, Open / close switch 3
A signal is input from the information display unit 1 and the information display unit 32
To output the opening degree information to the flow rate control valve 13, and to output the closing signal to the pressure control valve 10 and the flow rate control valve 13 based on the signal from the stop key 28. A configured fuel refueling device such as the servicer 1 is also conceivable.

Secondly, conversely, it is conceivable that only preset refueling is possible. That is, the preset refueling can be controlled by the microcomputer MC as the control means (the manual refueling is not controlled). In the case of the preset refueling, the preset amount is input in the same manner as described above. Based on this, an opening / closing signal is appropriately output to the pressure control valve 10 and the flow rate control valve 13, and opening information corresponding to the preset amount is output to the information display unit 32, and an opening signal is sent to the flow rate control valve 13. A fuel refueling device such as the servicer 1 configured to output is also conceivable.

Thirdly, in the fuel refueling device such as the servicer 1 or the like, both or one of the manual refueling and the preset refueling is possible, and together with this, a purely manual refueling as in the conventional example of this kind. Of course, the method of refueling is also possible. That is, each pressure gauge M1, M2, M3, M4, M5
The manual type refueling in which the pressure control valve 10, the flow rate control valve 13 and the like are manually operated to adjust the predetermined refueling pressure, refueling flow rate, and refueling amount by seeing the meter display such as It is possible to use it without depending on the preset refueling.

Fourth, in the illustrated example, the servicer 1 is shown as an example of the fuel refueling device, but the present invention is not limited to this, and a fuel refueling vehicle or other mobile fuel refueling device can be used. Conceivable. For example, the fuel refueling vehicle is equipped with a tank unlike the servicer 1, and the fuel oil loaded in this tank is supplied to the refueling pipe 6 by a vehicle-mounted pump to refuel.

[0033]

As described above, in the fuel refueling apparatus according to the present invention, based on the signals from the respective pressure sensors, flow meters, etc., the control means causes the information display section to display predetermined information and the pressure control valve, While appropriately outputting a close signal to the flow control valve, the control means further enables predetermined manual lubrication in claim 1, preset preset lubrication in claim 2, and both in claim 3. By doing so, the following effects are exhibited.

First of all, information such as the pressure value of each part of the oil supply pipe, the oil supply flow velocity, the amount of oil supply, the opening of the flow control valve, etc. is provided at a location distant from the location of the oil supply pipe, oil supply equipment, etc. It becomes possible to read and monitor it on the refueling work table or on the ground nearby. Secondly, the pressure control valve and the flow rate control valve can be remotely operated in the same manner at remote locations, and control to a predetermined refueling pressure, refueling flow rate, refueling amount, etc. is facilitated. In claim 1, a highly automated manual refueling is realized, in claim 2, a fully automated preset refueling is realized, and in claim 3, both of them are selectively realized. Thirdly, when an abnormality occurs in the pressure value, the refueling flow velocity, the refueling amount, etc. of each part, the pressure control valve and the flow rate control valve are automatically and immediately closed to stop the refueling. Therefore, by these first, second and third, accuracy and safety of the refueling work to the aircraft are remarkably improved, and the refueling work can be performed easily and easily. The effects of the present invention such as being swept away are remarkable and great.
