Next, the processing operation when the control device 11 detects a half door will be described.

FIG. 4 is a flowchart showing a main processing operation in the control device 11 in the mechanical parking device.

In step S1, the half-door detection unit 17 of the control device captures a signal when the lifting device 10 starts descending from the passenger compartment 1 to start the process, and in step S2, detects a signal from the detection sensors 6A and 6B. The light emitted from the detection sensor 6A is monitored for a certain period of time to detect whether the light in the half-door state is blocked. As a result, when the half-door state is not detected, the normal processing unit of the control device 11 continues the storage process of the parked vehicle 5 and completes the process in step S3.

However, when the half-door detection unit 17 detects a half-door state, the forced stop unit 18 of the control device 11 gives a stop signal to the lifting device 10 to stop it in step S4, and the parking vehicle 5 is stopped by a buzzer or the like. Notify the driver or parking manager of the half-door condition.

At this point, the image monitoring unit 19 of the control device 11 displays a screen on the display unit 12 of the operation panel 2 using the image data of the passenger room cameras 8 and 9 in step S5. The driver of the parked vehicle 5 or the parking lot manager who receives the notification of the half-door state looks at the screen display on the display unit 12 of the operation panel 2 in step S6, and the person in the parked vehicle 5 or the passenger compartment 1 Check whether the vehicle is not in the car.

When the screen display is performed, it is assumed that the driver of the parked vehicle 5 is still near the operation panel and looks at the screen display, and recalls that there is a passenger who has left the parked vehicle 5 temporarily. Alternatively, it is assumed that the parking lot manager who saw the screen display confirms that there is a person in the parked vehicle 5 or in the passenger compartment 1 from the image data.

At this time, the driver of the parked vehicle 5 or the parking lot manager operates the dispatch request button 15 on the operation panel 2 or the like to operate the forced stop continuation/caller 21. Then, in step 7, the forced stop continuation/call unit 21 of the control device 11 requests the dispatch of the center maintenance personnel while maintaining the stopped state of the elevating device 10. If there is a person in the parked vehicle and the door is in a half-door state, it may include a child left in the vehicle opening the door in order to get off the door by himself. However, since the lifting device 10 is held in a stopped state, the occurrence of this serious accident can be prevented.

The center maintenance personnel who have been dispatched through the forced stop continuation/calling section 21 have specialized knowledge and experience, and can utilize them to take appropriate measures. After the completion of the appropriate treatment, the center maintenance staff operates the safety confirmation button 16 or the like of the operation panel 2 in step S8. Then, in step S9, the forced stop release unit 22 of the control device 11 detects this as the determination result of the in-vehicle confirmation determination unit 20, and releases the operation inhibition by the forced stop unit 18 and the forced stop continuation/calling unit 21. In addition, the original position returning unit 23 of the control device 11 operates so as to return the lifting device 10 to the original position before the start of the descent.

After that, the process returns to step S1, and in step S3, the normal processing unit of the control device 11 restarts the storage process of the parked vehicle 5 to complete the process.

On the other hand, when the screen display of step S5 is performed, the driver of the parked vehicle 5 is still near the operation panel 2 and sees the screen display to know that there is no person in the car but the door is in a half-door state, or It is assumed that the parking lot manager who sees the screen display confirms from the image data that there is no person in the parked vehicle 5. When the driver of the parked vehicle 5 or the parking lot manager operates the safety confirmation button 16 or the like of the operation panel 2 as this confirmation operation, the original position returning unit 23 of the control device 11 lowers the elevating device 10 in step S10. It automatically returns to the original position before the operation started.

After that, in step S11, the half-door cancellation notification unit 24 of the control device 11 notifies the display unit 12 of the operation panel 2 to cancel the half-door state. The driver of the parked vehicle 5 or the parking lot manager who sees the display at this time approaches the parked vehicle 5, cancels the half-door state, and operates the safety confirmation button 16 or the like of the operation panel 2 after the completion of the canceling work. .. Then, the process returns to step S1, and as shown in step S3, the normal processing unit of the control device restarts the storage process of the parked vehicle 5 to complete the process.

Looking at the screen display using the image data of the entry and exit cameras 8 and 9 by the image monitoring unit 19 as described above, it is determined that the driver of the parked vehicle 5 or the parking lot manager does not have a person in the vehicle but is in a half-door state. When the determination is made, unlike the above case, the forced maintenance continuation/center maintenance personnel dispatched through the calling unit 21 are not dispatched. Therefore, the half-door state of the parked vehicle 5 can be eliminated in a relatively short time, so that the utilization efficiency of the mechanical parking device can be improved. In this way, even when the lifting device 10 detects that the moving parked vehicle 5 is in a half-door state, it can be efficiently operated while preventing a serious accident as a whole. ..
