Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a multilevel parking system that prevents a person from being trapped inside the parking system.

Multilevel parking systems are widely used in densely populated residential areas as parking facilities that can efficiently park a large number of vehicles on land with limited space. provided. In general, a multi-storey parking system is provided with an entry/exit space at one or more locations, and a parked vehicle moves in and out of the entry/exit space by self-running. A transport device for transporting a vehicle is provided between the entering/leaving space and the parking space, and the vehicle is mounted on the transport device in the entering/leaving space and transported to a predetermined parking space for storage. The entry/exit entrance of the entry/exit space is provided with a door that isolates the space from the outside. A driving control panel for operating the multi-storey parking system is provided near the door outside the multi-storey car parking system, and is operated by the manager of the parking system or the driver of the vehicle to open/close the door or transport the car. Operation of the device is performed.

In recent years, in addition to being used in commercial facilities, multi-storey parking systems are often used alongside office buildings, condominiums, and other housing complexes. In many cases, a specific user himself/herself performs the driving operation of the multi-storey parking system. However, when the multi-storey parking system is operated by the user himself/herself, not by the operation of a professional manager, other people may enter the multi-storey car park system due to lack of attention or lack of confirmation by the user. There is a possibility that the door will be closed while being left behind. For example, if a third party accidentally operates the operation panel while the user is inside the multi-story parking system, or if a third party This is the case, for example, when the user intrudes into the device and closes the door without knowing this.

For this reason, conventionally, as a method of confirming the presence of a person in a multi-storey parking system, a technique of detecting a person with a photoelectric sensor (see, for example, Patent Document 1), an image is taken with an imaging device, and the image is processed. technology to detect by using a microwave (see, for example, Patent Document 2), a technology to irradiate microwaves and detect them with a Doppler sensor (see, for example, Patent Document 3), etc. are known, and these allow the presence of a person to be detected. And it prevents the operation of the multi-story parking device. There is also known a technique for detecting that a person is trapped in a parking lot by collecting sounds generated in the parking lot and determining the sounds (see, for example, Patent Document 4).

The loading/unloading room 15 is provided with a sliding entrance/exit door 22 at an entrance/exit 27 through which a vehicle 19 enters and exits, and an operation panel 21 is provided on an outer wall near the entrance/exit door 22.例文帳に追加The operation panel 21 is equipped with buttons for selecting entry and exit, a touch panel, a display, an authentication device, etc. When the user operates the operation panel 21, the control device controls the operation of the parking structure 10. do. Further, the entering/leaving room 15 is provided with a plurality of cameras 25 at positions where the inside of the entering/leaving room 15 can be photographed and the inside of the vehicle 19 can be satisfactorily photographed. An image captured by the camera 25 is displayed on the display of the operation panel 21 .

The camera 25 is a camera 25 having a machine-learning-completed learning-type artificial intelligence function, and learns the shapes of people and vehicles from a large amount of image data. can be identified and detected. The signal from the camera 25 controls the operation of the parking structure 10 at the time of entry and exit as follows. First, when entering the parking lot, the user performs a predetermined operation on the operation panel 21 to start driving the multi-storey parking system 10 . When the carrier 13 loaded with the empty pallet 18 stops in the loading/unloading room 15, the loading/unloading door 22 opens and each camera 25 starts photographing. It is assumed that the operation of the three-dimensional parking device 10 is kept stopped. After that, the user drives the vehicle 19 and moves into the entrance/exit room 15, and each camera 25 detects people in the vehicle 19, and controls the number of people in the detected vehicle 19. Send to device. Normally, only the driver gets on and moves to the loading/unloading room 15, so the number of people detected by each camera 25 is one. It is also assumed that

When the vehicle 19 stops in the loading/unloading room 15, each camera 2 detects this and transmits a signal to the control device. Next, the passenger of the vehicle 19 gets off and exits through the entrance/exit door 22 . At this time, each camera 25 detects the number of people leaving through the entrance/exit door 22, and transmits the number of people who have left to the control device. The control device compares the number of people on board the vehicle 19 when the vehicle 19 enters with the number of people who have exited from the entrance/exit door 22 based on signals from each camera 25 . Then, when the number of people who left is equal to the number of people who were on board, the operation of the operation panel 21 is validated and the user can operate it.

On the other hand, when the user who has left closes the entrance/exit door 22 on the operation panel 21, if the number of people who have left is smaller than the number of people on board, for example, the operation panel 21 The equipped speaker or the like emits a voice such as "A person may remain in the car or in the parking lot. Please check the parking lot again" to prompt the user to reconfirm. Thereafter, when the user performs confirmation work in the loading/unloading room 15, each camera 25 detects this and transmits a signal to the control device. Upon receiving this signal, the control device activates, for example, a "safety confirmation end" button provided on the operation panel 21, and when the user presses this button, subsequent operation of the operation panel 21 is validated. . Subsequently, when the user presses the button for closing the entrance/exit door, the multi-level parking device 10 starts to operate, and after the entrance/exit door 22 is closed, the vehicle 19 is stored in the predetermined parking room 17 . In any of the above stages, when each camera 25 detects a person in the entering/exiting room 15, the operation of the parking structure 10 is not started or stopped.

Next, when leaving the parking lot, the user performs a predetermined operation on the operation panel 21 to start driving the multi-storey parking system 10 . When the carrier 13 carrying the vehicle 19 stops in the loading/unloading room 15, the loading/unloading door 22 is opened and each camera 25 starts photographing. Next, the user moves from the entrance/exit door 22 to the vehicle 19 , gets on the vehicle 19 , and then drives the vehicle 19 to leave the entrance/exit door 22 . Each camera 25 detects the exiting vehicle 19, and outputs this signal to the control device when no person is detected in the entrance/exit compartment 15 when the exit of the vehicle 19 is completed. With this signal, the control device validates the operation on the operation panel 21, and the user operates the operation panel 21 to close the entrance/exit door 22. FIG.

On the other hand, when the camera 25 detects a person in the entrance/exit room 15 after the vehicle 19 has left, for example, a speaker or the like provided on the operation panel 21 may say, "There is a possibility that a person remains in the vehicle or in the parking lot." There is. Please check the parking lot again." to urge the user to reconfirm. Thereafter, when the user performs confirmation work in the loading/unloading room 15, each camera 25 detects this and transmits a signal to the control device. Upon receiving this signal, the control device activates, for example, a "safety confirmation end" button provided on the operation panel 21, and when the user presses this button, subsequent operation of the operation panel 21 is validated. . Subsequently, when the user presses the button for closing the entrance/exit door, the entrance/exit door 22 of the multi-storey parking device 10 is closed, and the unloading operation is completed.

According to the above configuration, when a person is present in the loading/unloading room 15, the camera 25 having the function of machine-learned learning-type artificial intelligence dynamically detects the person more accurately, and the operation panel 21 detects the person. Since the operation of is invalidated, it is possible to prevent a person from being confined in the loading/unloading room 15.例文帳に追加Also, in the case of entering the vehicle, the passenger in the moving vehicle 19 is detected. A person can be detected more accurately. Furthermore, when a person is left behind in the loading/unloading room 15, after urging the user to reconfirm, the camera 25 detects that the user has reconfirmed, and the operation panel 21 detects that the user has reconfirmed. By validating the operation, it is possible to further enhance safety.
