FIG. 1 is a plan view showing an example of a mechanical parking device 100 provided with the operation panel 10 of the present invention.
The mechanical parking device 100 includes a control device 50 that controls its operation. Further, the control device 50 has a first communication device 52 that communicates bidirectionally with the operation panel 10.
The mechanical parking device 100 is, for example, an elevator system, a vertical circulation system, or the like, but the present invention is not limited to this, and other mechanical parking devices including the control device 50 may be used.

In this example, the mechanical parking device 100 includes a boarding / alighting room 2 in which the vehicle 1 enters or exits, an entrance / exit door 3 of the boarding / alighting room 2, and an internal camera 5 provided inside the boarding / alighting room 2 to take an image of the boarding / alighting room. It has a monitoring monitor 6 provided outside the boarding / alighting room 2 and monitoring the boarding / alighting room.
Further, in this figure, M is an operator (for example, a driver), 2a is a wall of the boarding / alighting room 2, 2b is an entrance / exit of the boarding / alighting room 2, and 4 is a pallet (or a boarding / alighting area of the vehicle 1).

The operator M may be a person who has a contract with the user (for example, the driver of the vehicle 1) to directly operate the operation panel 10 for warehousing or warehousing.
The operation panel 10 of the present invention is installed outside the boarding / alighting room 2, for example, at a location near the doorway 3 (for example, the wall 2a). The operation panel 10 is preferably embedded in the wall surface, but may be exposed.

2A and 2B are explanatory views of the operation panel 10, where FIG. 2A is a front view and FIG. 2B is a block diagram.

In FIG. 2A, the operation panel 10 has an authentication device 12, a display device 14, a speaker 16, an operator detection sensor 18, and an operation button 20. In this example, these are provided on the board surface of the operation panel 10, but a part thereof may be provided at another place.
In FIG. 2A, 22 is a changeover switch for switching between automatic and manual, and 24 is an emergency stop button.

The authentication device 12 authenticates the operator M. In this example, the authentication device 12 is a card reader that communicates with the IC card of the operator M in a non-contact manner. The authentication device 12 is not limited to the card reader, and the operator M may be authenticated by a smartphone or a remote controller.
Further, the authentication device 12 may be a biometric authentication device such as fingerprint authentication, face authentication, and iris authentication.

The display device 14 is a display device that displays characters or images. The display device 14 displays an operation message such as "Please hold your hand" or "Check the safety in the refrigerator".
The speaker 16 outputs sound. The speaker 16 outputs, for example, the same operation message as the display device 14 by voice.
In the plurality of standby states A (described later) of the mechanical parking device 100, the display device 14 or the speaker 16 outputs an operation message corresponding to the standby state A.

The operator detection sensor 18 detects the operator M at a predetermined position. The predetermined position is a position where the operation panel 10 can be operated, and is preferably near the front surface of the operation panel 10.
The operator detection sensor 18 is an infrared sensor in this example, but may be another sensor (for example, an ultrasonic sensor, etc.) as long as it can detect the operator M at a predetermined position. Further, the infrared sensor is preferably a passive sensor (infrared passive sensor).

The operation button 20 is single (only one) in this example, and outputs a single operation signal b by operation. The operation button 20 is preferably a non-contact type, for example, an electrostatic type sensor as a countermeasure against corona infection.
The operation button 20 is not limited to the non-contact type, and may be a contact type or a push button type.

Further, it is preferable that the operation button 20 can display the "non-operating state" that does not accept the operation and the "operating state" that accepts the operation by the emission color (for example, red and blue) of the button or turning off and blinking.
Instead of or in combination with the display of the operation button 20, the display device 14 or the speaker 16 may output the "non-operation state" and the "operation state" of the operation button 20.

In FIG. 2B, the operation panel 10 further includes a second communication device 26 that bidirectionally communicates with the control device 50 of the mechanical parking device 100, and a controller 30 that controls the operation buttons 20. ing.
The second communication device 26 receives the state signal a from the control device 50 and outputs the control signal c to the control device 50.

The controller 30 receives the state of the authentication device 12, the operator detection sensor 18, the operation button 20, the changeover switch 22, and the emergency stop button 24 or the received signal from these, and receives the display device 14, the speaker 16, and the controller. Output the signal or data required for 30. The controller 30 is a computer (PC) having, for example, an input device, an output device, a storage device, and an arithmetic unit.

The controller 30 outputs a control signal c corresponding to a plurality of different standby states A to the control device 50 by a single operation signal b of the operation button 20 in the plurality of standby states A of the mechanical parking device 100.
The plurality of standby states A are, for example, after authentication by the authentication device 12, after the operator M enters the vehicle 1 and exits from the boarding / alighting room 2, or after confirming that the boarding / alighting room 2 is unmanned.
Further, the state signal a corresponding to the standby state A is, for example, an authentication confirmation signal a1, an exit confirmation signal a2, and an unmanned confirmation signal a3.
Further, the different control signals c corresponding to the plurality of standby states A are the start signal c1 after the authentication by the authentication device 12, the unmanned confirmation signal c2 after the operator M has left the boarding / alighting room 2, or the unmanned confirmation signal c2 after the unmanned confirmation. It is a door closing signal c3 for closing the doorway 3.

FIG. 6 is a timing chart showing the relationship between the operation signal b and the control signal c in the standby state A.

FIG. 6A is an example of using the rising signal of the operation signal b.
In this example, the control signal c is output when the operation signal b continues for a predetermined time from the rising edge in the standby state A. In this case, the predetermined time is preferably, for example, about 0.5 to 2 seconds.
Further, when the operation button 20 is operated before the state signal a (unmanned confirmation signal a3 in this example) is output, the rising signal of the operation signal b is not generated after the state signal a is output, so that control is performed. The signal c is not output. Further, even when the duration of the operation signal b (t3 in this example) is less than the predetermined time, the control signal c is not output.
With this configuration, since the control signal c is not output unless the operation button 20 is operated after the standby state A is reached, it is possible to prevent the next operation from proceeding while holding the hand, for example.

FIG. 6B is an example of using the falling signal of the operation signal b.
In this example, the control signal c is output when the operation signal b falls in the standby state A.
That is, the controller 30 outputs the control signal c when the operator M operates the operation button 20 and removes his / her hand.
For example, when the operation button 20 is a non-contact type, the control signal c is output "when the hand is removed" without proceeding to the next operation while holding the hand over the operation button 20. The same applies to the contact type or the push button type.
In this example, when the operation button 20 is operated before the state signal a (in this example, the unmanned confirmation signal a3) is output, the control signal is based on the falling signal of the operation signal b after the state signal a is output. c is output. Further, since the state signal a and the operation signal b are turned off after the output of the control signal c, the control signal c is not output thereafter.
With this configuration, since the control signal c is not output unless the hand is removed from the operation button 20, for example, it is possible to prevent the user from proceeding to the next operation while holding the hand.

FIG. 3 is a flow chart showing a control method of the mechanical parking device 100 and the operation panel 10.
In this figure, this control method has steps (steps) of S1 to S15 at the time of warehousing of the vehicle 1.

In FIG. 3, the vehicle 1 is stopped in front of the doorway in step S1, and the operator M holds the card over, for example, a card reader in step S2, and the authentication device 12 authenticates the operation.
The control device 50 of the mechanical parking device 100 confirms the authentication (S11), and outputs the authentication confirmation signal a1.

In step S3, the display device 14 and the speaker 16 output an operation message. For this operation message, for example, "Please hold your hand over the operation button to start.", "If the operation button is blinking, check the safety on the monitoring monitor and then hold your hand over the operation button. ".", "Please hold your hand over the operation button after the operation button turns blue."

In step S4, when the operator M operates the operation button 20 (for example, holding his / her hand over the operation button 20), the start signal c1 is output by the operation signal b of the operation button 20, and the mechanical parking device 100 calls for warehousing. The door 3 is opened by the operation (S12).

Next, in step S5, the operator M starts the operation to perform the warehousing operation, and after the warehousing operation is completed, the operator M leaves the boarding / alighting room 2. When the mechanical parking device 100 confirms this exit, the exit confirmation signal a2 is output from the control device 50 (S13).
In step S6, the display device 14 and the speaker 16 output an operation message. This operation message is, for example, "Check visually and on the monitoring monitor that there are no people in the parking lot and that there is no misplacement of luggage, etc.""Please hold your hand over the operation button after confirming that there is no person." And so on.

Next, in step S7, when the operator M operates the operation button 20 (for example, holding his / her hand over the operation button), the unmanned confirmation signal c2 is output to the mechanical parking device 100 by the operation signal b of the operation button 20. .. When the mechanical parking device 100 confirms the safety of the boarding / alighting room 2 and receives the unmanned confirmation signal c2, the unmanned confirmation signal a3 is output from the control device 50 (S14).

Next, in step S8, the display device 14 and the speaker 16 output an operation message. This operation message is, for example, "Please hold your hand over the operation button to close the door." "If the operation button is blinking, check the safety again on the monitoring monitor and then hold your hand over the operation button. Please. ", Etc.

Next, when the operator M operates the operation button 20 (for example, holding his / her hand over the operation button) in step S9, the door closing signal c3 is output to the mechanical parking device 100 by the operation signal b of the operation button 20. ..

Next, in step S10, the operator M holds the card over, for example, a card reader, and the authentication device 12 authenticates the operation.
Upon receiving the door closing signal c3 and the operation authentication signal, the mechanical parking device 100 starts the closing operation of the door 3 (S15), closes the door 3 (fully closed), and ends the warehousing operation.

When the vehicle is delivered, the warehousing operation is replaced with the warehousing operation, but the other control methods are the same.

According to the above-described embodiment of the present invention, the operation button 20 for outputting the operation signal b is single, and in the plurality of standby states A of the mechanical parking device 100, the single operation signal b of the operation button 20 is used. A different control signal c corresponding to each of a plurality of standby states is output.
Therefore, since there is only one operation button 20, there is no possibility of accidentally operating another operation button, the operation is easy, and erroneous operation can be reduced.

Further, since the controller 30 outputs different control signals c corresponding to each standby state A of the mechanical parking device 100 in the plurality of standby states A of the mechanical parking device 100, there is a possibility of misidentification of the operator M. There is no such thing, and safety can be improved.

The control method of the operation panel according to the present invention uses the operation panel 10 described above, and corresponds to each of the plurality of standby states by a single operation signal b of the operation button 20 in the plurality of standby states A of the mechanical parking device 100. Output different control signals c.

FIG. 4 is a flow chart showing a first embodiment of the control method of the operation panel 10 according to the present invention.
In this figure, the control method of the operation panel 10 has steps (steps) of T1 to T9 at the time of warehousing and at the time of warehousing.

The controller 30 receives the above-mentioned plurality of standby states A, that is, state signals a corresponding to the standby states A (for example, authentication confirmation signal a1, exit confirmation signal a2, unmanned confirmation signal a3) as follows. Works on.

The operation button 20 is maintained in an "inactive state" in which the operation is not accepted except in the standby state. The non-operation state is preferably displayed by the emission color of the operation button 20 (for example, red) or by turning off and blinking the operation button 20.

In step T1, it is determined whether or not the mechanical parking device 100 is in the plurality of standby states A described above. If NO, the operation button 20 is kept inactive and waits.
If either standby state A is set and T1 is YES, it is determined whether or not the operator M has been detected by the operator detection sensor 18. If NO, the operation button 20 is kept inactive and waits.

When the operator M is detected and YES in step T2, the operation button 20 is switched from the "non-operating state" to the "operating state" for accepting the operation in step T3. The operating state is preferably displayed by the emission color of the operation button 20 (for example, blue) or the lighting of the operation button 20.

Further, at the same time as step T3, in step T4, a timer for measuring the elapsed time of the operating state of the operation button 20 is activated.
The operation time (set time) of the operation button 20 varies depending on the different standby states A, and is preferably 2 to 10 seconds, for example.
In step T5, when the elapsed time of the operating state exceeds the set time, the operation button 20 is switched to the non-operating state in step T8.
Then, in step T9, the authentication by the authentication device 12 is performed again, and the process returns to step T1.

Further, even if the detection signal by the operator detection sensor 18 in step T2 is interrupted while the timer is operating, the operation button 20 is switched to the inactive state in step T8, and the authentication by the authentication device 12 is performed again in step T9. And return to step T1.

If the elapsed time of the operating state is less than or equal to the set time in step T5, the operation of the operation button 20 (step T6) causes a single operation signal b in step T7 to provide a different control signal c corresponding to each standby state A. Is output.

According to the control method described above, when the operator M is detected by the operator detection sensor 18, the operation button 20 is switched from the non-operating state to the operating state.
Further, if the operator M moves away from a predetermined position in front of the operation panel after the operator M is detected by the operator detection sensor 18, the detection signal of the operator detection sensor 18 is interrupted, so that the operation button 20 is not used. It can be switched to the operating state.
Therefore, when the operator M is not in the predetermined position, it is possible to prevent the operation of the operation button 20 by a child or another person.

Further, the controller 30 is a single control according to the standby state by the operation signal b of the operation button 20 when the operation button 20 is operated within the operation time in which the elapsed time is set in advance while the timer is operating. The signal c is output.
When the elapsed time exceeds the operation time, the operation button 20 is switched to the non-operating state to invalidate the operation of the operation button 20.

Therefore, when the operator M is separated from the predetermined position beyond the operation time of the timer, the operation button 20 becomes inactive and the operation of the operation button 20 by a child or another person can be prevented.

Further, according to the present invention, the operation authentication by the authentication device 12 starts the closing operation of the doorway 3 in S12, the doorway 3 is closed (fully closed), and the warehousing operation is completed. It is possible to prevent the malicious operation of the person.

Further, in the control method described above, the operator M has a predetermined operation time in a state where the mechanical parking device 100 is in each standby state A and the operation button 20 is in the operating state at a predetermined position of the operation panel 10. Only a single operation button 20 is operated within. Therefore, the operation is easy and erroneous operation can be almost eliminated.

FIG. 5 is a flow chart showing a second embodiment of the control method of the operation panel 10 according to the present invention.
In this figure, the control method of the operation panel 10 has each step (step) of T11 to T17.

That is, when the controller 30 receives the above-mentioned plurality of standby states A, that is, the state signals a corresponding to the standby states A (for example, the authentication confirmation signal a1, the exit confirmation signal a2, and the unmanned confirmation signal a3), the controller 30 is described below. Works like this.
In step T11, it is determined whether or not the above-mentioned plurality of standby states A are present. If NO, wait in that state.

If YES in step T11, the required number of operations of the operation button 20 is output as a random number N by the display device 14 or the speaker 16 in step T12. This random number N is, for example, an integer of 1 to 5.
When the operation button 20 is operated in step T13, the number of times of the operation button 20 within the set time is counted. The set time is preferably, for example, 2 to 10 seconds.
For the operation of the operation button 20, for example, when the operation button 20 is a non-contact type, it is necessary to repeat the operation of "holding the hand over the operation button 20 and then releasing the hand". In the case of "holding your hand", it is counted as one time.
This makes it possible to prevent malfunctions when "holding your hand".

In step T14, when the number of operations of the operation button 20 matches the random number N (YES), the controller 30 outputs a single control signal c according to the standby state in step T15.
Further, in step T14, when the number of operations does not match the random number N (NO), the operation button 20 is switched to the non-operating state in step T16, and the operation of the operation button 20 is invalidated. In this case, then, in step T17, the authentication by the authentication device 12 is performed again, and the process returns to step T11.
Also in the method of FIG. 5, it is preferable to use steps T2 to T9 of FIG. 4 in combination.

According to the control method described above, the operator M can be alerted when the operator M unconsciously holds his / her hand over the operation button 20. Further, since the operation cannot be continued unless the random number N is recognized, a malicious operator can be excluded.

The methods of FIGS. 4 and 5 may be used in combination. For example, by first implementing the method of FIG. 4, the operation is easy, erroneous operation can be reduced, and safety can be ensured.
Further, when the operation authentication (T9) is repeated by the method of FIG. 4, for example, by switching to the method of FIG. 5, the operator M can be alerted and the malicious operator is eliminated. be able to.

In the above-mentioned example, the operation button 20 is single (only one), but the present invention is not limited to one, and a plurality of operation buttons may be provided.
For example, a "clockwise button" and a "counterclockwise button" may be added for operating the turntable.
In this case as well, since the number of operation buttons can be significantly reduced, there is less possibility of accidentally operating another operation button, and the operation is easy and the number of erroneous operations can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
