This is a safety device that can operate the lifting device on the condition that it is not in the boarding area, reducing the safety work that can prevent accidents due to carelessness and unconfirmed by the administrator, etc., and providing a safer detector To do.

  FIG. 1 is a pallet-type or fork-type mechanical type of multi-story parking apparatus 1 and is not limited, and can be adopted as a tower type or a multistage multi-row type. In this specification, a fork type is taken as an example. Detailed description will be made with reference to the drawings. The multi-story parking device 1 includes a lifting space 8 having a ground surface GL as a boarding place S and a transport device (called lifting lift) 3 arranged in the center so that it can be lifted up and down from the pit P to the top floor. A parking room 9 is provided on a plurality of floors adjacent to the left and right.

  The lift 3 is suspended from the drive unit 4 on the uppermost floor via the cord-like body 5 and is guided by guide rails 7 erected at the four corners of the lift space 8 to include a fork on which a vehicle 12 can be mounted. ing. In the parking room 9, a mounting table (referred to as a transverse tray) 2 is arranged. The traversing tray 2 is traversed to the lifting / lowering space 8 by the traversing device 6 to deliver the lifting / lowering lift 3 and the vehicle 12 and then traverses back to the original parking chamber 9 to be stored back.

  The delivery of the vehicle 12 has a difference between the warehousing operation and the warehousing operation, but in the ascending / descending space 8, the elevating lift 3 is moved up and down and the traversing tray 2 is moved in a horizontal direction to move from the traversing tray 2 to the lifting lift 3 or from the lifting lift 3. The loading / unloading vehicle 12 can be transferred to the transverse tray 2. The traversing device 6 is traversed by supporting the rails provided at the front and rear ends of the traversing tray 2 with a plurality of rollers and driving and rotating the rollers. The fork of the lift 3 can be mounted with the tires of the vehicle 12 such that the forks protrude in a comb shape from both sides in the longitudinal direction of the lift space 8 toward the inside.

  The fork of the traversing tray 2 is provided in a comb-like shape outwardly from a member that connects and supports the center of the front and rear ends, and the tire of the vehicle 12 is mounted on the fork. The fork of the lifting lift 3 and the fork of the traversing tray 2 are arranged so that they can pass between the forks. When the lifting lift 3 moves up and down on the traversing tray 2 stopped in the lifting space 8, You can pass between the forks.

  The boarding place S is in the lifting space 8 on the ground surface GL, and the lifting lift 3 is integrated with the floor surface to form a passage with few gaps, and is provided with an opening 10 for getting into the passage. The gate 15 is provided so as to be movable up and down so that the machine can be operated safely by restricting the entrance and exit of people in the apparatus. The opening 10 is used for the entrance and exit of the vehicle 12 and the passage for passengers. Normally, the gate 15 is closed to prevent entry and exit.

  FIG. 2 shows a boarding place S, which forms a passage in which a lift space 8 is provided in a straight line direction with the opening 10 as an entrance and the lift lift 3 is stopped, and a floor surface is provided adjacent to this passage and the driver. It is a boarding area for passengers. In this boarding area S, a plurality of cameras 13 are arranged to photograph the passengers on the vehicle 12 and input the video to the personal computer 14. The personal computer 14 is provided with data of the vehicle 12 that has entered the vehicle, searches the number of doors by how many people this vehicle 12 has received, stores how many people have exited from which door, and how many people have exited the boarding area S. It can be safely managed by calculating and instructing the operation panel 11. As for the position of the camera 13, the camera 13 a is disposed at the front of the vehicle in the lift space 8, the cameras 13 b and 13 c are disposed at the left and right of the front, and the cameras 13 d and 13 e are disposed at the left and right of the rear opening 10. .

Each camera 13 allows the camera 13a to pass through the windshield so that the driver's seat, the assistant seat and the rear seat can be photographed. The cameras 13d and 13e are arranged so as to be able to capture a person exiting from the opening 10 of the boarding area S.
The personal computer 14 searches for the vehicle type and memorizes that it is a four-door four-seater, analyzes the input signal of the camera 13, remembers that four people are on board, B, C, and D will be tracked. When these four passengers A, B, C, and D exit from the opening 10 of the boarding place S, the operation panel 11 of the multi-story parking apparatus 1 can be activated and can be stored.

  FIG. 3 is for tracking occupants A, B, C, and D. A plurality of people are confirmed on the camera 13, but four people are searched on the screen on the personal computer, and names are displayed with symbols. Yes. The camera 13b that searches for the door on the right side of the vehicle 12 reflects the occupants A and C and transmits them to the personal computer 14 so that the personal computer 14 records the movement and shows the trajectory. The camera 13C searching for the door on the left side of the vehicle 12 shows the occupants C and D, and the personal computer 14 indicates the movement as a locus. The trajectory of the occupant 13 indicates the inside of the boarding place S, and exiting from the opening 10 ends only the occupant 13 and disappears.

  FIG. 4 shows that the camera 13a can take a picture of the occupant A still in the car, the occupant D has gone out of the opening 10 and has disappeared, the camera 13d has taken the picture when the occupant C goes to the opening 10, and the camera 13e gets in. Since the passenger B in the field S is photographed and this information is input to the operation panel 11, the three-dimensional parking apparatus 1 is restricted from operating.

  FIG. 5 shows the trajectory of the occupant A taken by the camera 13d, and waits for the occupant B to exit and the occupant A to exit. FIG. 6 shows a state in which no one is shown on the camera 13 and no one is present, and the operation panel 11 can be operated, and commands a warehousing operation.

  FIG. 7 is a diagram in which the video of the camera 13 is input to the personal computer 14, the face memory 16 detects a person from the input video, and information that invalidates the operation of the multi-story parking apparatus 1 when the person is “present”, It outputs to the operation panel 11 and makes the state where entry / exit operation is impossible. When it is determined that there is no person by detecting this video, the multi-story parking apparatus 1 can be operated, and information can be output to the operation panel 11 to enable entry / exit.

  FIG. 8 includes a face memory 16 for detecting a person's face by detecting the person's face from the video of the camera 13 by software of the personal computer 14 in order to detect a person. The face memory 16 detects a person's face in the image, attaches an identification number to each detected face difference, and tracks the movement of the identification number with a plurality of cameras 13. , Discriminate against other faces with symbols, and calculate and manage the number of symbols based on existing symbols. The face of the image is recognized by the eyes, nose and mouth, and a difference is obtained by measuring the distance between both eyes 17, the distance between eyes 18 and 19, and the distance between eyes 20 and 21. The same person can be confirmed even in the video of the camera 13 and can be given the same identification number.

  Furthermore, if there is a margin, the size of eyes, nose, and mouth may be measured, and even if multiple cameras can be taken by the camera 13, the progress of the symbols can be tracked by the personal identification number by the personal computer 14. I am doing so. The face memory 16 can retrieve the warehousing location by calling the identification number by taking a picture with the camera 13 even when the warehousing location becomes unknown due to the loss of the parking card or the like with the identification number.

  The data of the vehicle 12 is input to the personal computer 14, and by detecting the number of passengers, the number of doors, etc. in the video of the warehousing vehicle, the system for taking the camera 13 is put on standby, and the film, curtain, awning, etc. Although there are things that cannot be confirmed by the shielding material, since there is no shielding material on the windshield, the problem is solved by detecting up to the rear seat by the camera 13a. The manager must check the number of drivers with the driver, but can increase safety as an interlock.

  The camera 13 may be a fixed type, but if it is a rotary type that tracks a moving body, it is possible to increase the safety by making it possible to zoom up from a wide-angle lens. At the boarding point S, an announcement is made to call attention so as to get off the vehicle 12 and leave the vehicle 12 to promptly leave.

  The present invention is capable of managing theft prevention not only by searching for a person in a room entering and leaving the vehicle like a multi-level parking apparatus, but also by identification numbers of the face memory of the operator at the time of entry and the face memory at the time of exit. . In addition, the number of people in and out of the room can be stored and the remaining number can be calculated, and the attendance and absence in the school classroom can also be obtained from the camera's video and the identification number stored in advance can give the result instantly. For example, it can also be provided to replace a boarding place for amusement park vehicles or a movie theater at a venue.
