BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door control device for a multi-story parking garage, which is capable of closing doors in a multi-story parking garage using equipment standardly equipped on vehicles.

0002

[Prior Art] The entry/exit entrance of a parking room that constitutes a vehicle entrance floor in a multi-story parking garage is usually equipped with a door that is automatically opened and closed by an electric system or the like. In a parking lot, an operator mainly opens and closes the doors. On the other hand, in multi-story parking garages where operators are not always present, users open and close the doors by operating operation panels installed on the outer wall or the like.

0003

[Problem to be Solved by the Invention] However, in multi-story parking garages where users operate the doors, it is necessary to get out of the vehicle to operate the operation panel, which is a troublesome task. It had become.

[0004] Therefore, in this type of multi-story parking lot, a wide sensor installed in the parking room detects that there is no person in the parking room, and a vehicle sensor detects that a vehicle has left the parking room. In some cases, there is a multi-storey parking lot that is equipped with a door control device that automatically closes the door, so that users do not have to get out of the vehicle when leaving the vehicle.
This had the advantage of reducing the burden on users.

However, in this case, the doors are automatically closed regardless of the user's intention to leave the vehicle, so there is a drawback that it is difficult to ensure the safety of people around the door. Ta.

On the other hand, a device for automatically opening and closing a door (shutter) in a parking lot without getting out of the vehicle was developed in Japanese Patent Laid-Open No. 61
Although there is a method disclosed in Japanese Patent No. 45077, it is necessary to separately install a transmitter in the vehicle, which has the drawback of causing a financial burden on the user.

[0007] In view of the above problems, the present invention makes it possible to close the door of a multi-story parking garage by utilizing the passing function of the headlights equipped as standard equipment on vehicles, thereby burdening the user with special equipment. To provide a door control device for a multi-story parking lot that does not require a user to get off the vehicle and can further improve safety.

[0008]

[Means for solving the problem] A technical means for achieving the above object is a multi-story parking structure in which a door that is controlled to open and close is provided at the entry/exit entrance provided in the parking room on the vehicle entrance floor. This door control device includes a person detector that detects whether there is a person in the parking room, a car detector that detects the position of a vehicle in the parking room, and a receiver that receives passing light from vehicle headlights from outside the entrance/exit. When the human detector detects that no one is present, and the car detector detects that no vehicle has entered the parking lot, the photodetector detects passing light in the closing request pattern. The present invention is provided with a door control unit that closes the door when the door is detected.

[0009]

[Operation] According to the present invention, after the user takes the vehicle out of the parking room, the user only has to perform a passing operation corresponding to the closing request pattern from inside the vehicle.

[0010] At this time, when the human detector is in the state of detecting the absence of a person,
If the vehicle detector detects that the vehicle has not entered the garage, the door control section is activated by the detection of the passing light of the closing request pattern by the photodetector, and the door is automatically closed.

On the other hand, if there is a person in the parking room, the person detector detects the person, so even if the photodetector detects light corresponding to the closing request pattern, the door control unit It does not work and the door does not close. Similarly, even when the vehicle is not in the warehouse, the vehicle detector is detecting the vehicle, so even if the photodetector detects light corresponding to the closing request pattern, the door control unit will not operate. , the door will not close.

[Example] Hereinafter, an example of the present invention will be explained based on the drawings. In Figs. 1 to 3, reference numeral 1 denotes a vertical circulation type multi-level parking lot, and a tower 2 has a large number of structures arranged in a ring in the vertical direction. A vehicle mounting cage 3 is provided. Each vehicle mounting cage 3 is connected to a pair of front and rear endless chains 5 via attachments 4, and the endless chains 5 are circulated by a drive device (not shown), so that each cage 3 is circulated within the tower 2. is configured to do so.

[0013] The ground floor of the tower 2 is configured with a parking room 7 as a vehicle entrance floor, and an entrance 8 for vehicles W to enter and exit is provided on the front wall 7a side of the parking room 7. The entrance 8 is equipped with a door 9 that is electrically controlled to open and close. Although the door 9 is shown to be slid open and closed from both sides of the entrance 8, it may have a shutter structure that is raised and lowered from above.

An operation panel 10 is provided on the outer wall side of the front wall 7a.
is provided, and by operating the driving operation panel 10, the user can call the empty cage 3 or the actual car cage 3 to the parking room 7 and open/close the door 9 from a control device (not shown). ing.

As shown in FIG. 1, a plurality of vehicle position sensors 13a, 13b, and 13c each consisting of a pair of a light emitter and a light receiver are arranged on both side walls 7b and 7c of the parking compartment 7. A vehicle detector 13 is configured to detect the position of a vehicle W entering a cage 3 that lands in a landing pit 12. In addition, in the passage section 14 on both sides of the cage 3, there are human detection sensors 15a, 15b, 15c, and 15d on the front wall 7a side and the rear wall 7d side, which are composed of a plurality of beam sensors, etc., each consisting of a pair of a light emitter and a light receiver. A person detector 1 is arranged respectively and detects whether there is a person in the passage section 14.
5. Furthermore, as shown in FIGS. 1 and 2, on the inner wall surface side of the rear wall 7d facing the entrance 8,
A passing light sensor 17 made of CdS, a phototransistor, etc. is arranged at an appropriate height and at an appropriate position so as to optimally receive the passing light from the headlight 16 of the vehicle W from outside the entrance/exit 8, and detects the passing light. It constitutes a photodetector.

The vehicle detector 13, the person detector 15, and the passing light sensor 17 are connected to a door control section 18 of the control device, as shown in FIG.
For example, any of the vehicle position sensors 13a, 13b, 1
3c detects the vehicle W, it outputs a high level signal (hereinafter referred to as H), and any vehicle position sensor 1
3a, 13b, and 13c are also configured to output a low level (hereinafter referred to as L) signal when the vehicle W is not detected. Similarly, the human detector 15 outputs an H signal when any of the human detection sensors 15a, 15b, 15c, 15d detects a person; The sensor is configured to output an L signal when no person is detected. On the other hand, the passing light sensor 17 is configured to output an H signal when it receives passing light, and output an L signal when it does not receive passing light.

The door control section 18 has two AND gates 19.
, 20, one input terminal of the first AND gate 19 is connected to the output terminal of the passing light sensor 17, and the other input terminal is connected to the vehicle detector 13 via the first inverter 21. output terminal is connected. Further, the output terminal of the first AND gate 19 is connected to one input terminal of the second AND gate 20, and the output terminal of the human detector 15 is connected to the other input terminal via the second inverter 22. has been done. and the second and gate 20
The output terminal of is connected to a passing pattern discriminator 23, the passing pattern discriminator 23 is connected to a door control circuit 24, and the door control circuit 24 is connected to a motor 25 for driving the door 9 to open and close.

The passing pattern discriminator 23 is for discriminating whether the on/off pattern of the passing light is a pattern for requesting the door 9 to close, and a predetermined closing request pattern is set in advance. Then, it compares and determines whether the signal pattern input from the second AND gate 20 side corresponds to a preset closing request pattern,
Only when it corresponds to the closing request pattern, the door closing signal is output to the door control circuit 24 as a door closing request signal. For example, as shown in FIG. 5, for a certain period of time (for example, 2 seconds)
A signal pattern corresponding to a predetermined number of passing on/off operations (for example, three times) may be set as a closing request pattern.

When the door close signal is inputted from the passing pattern discriminator 23, the door control circuit 24 drives the motor 25 in the door 9 closing direction to close the door 9. Furthermore, when the door 9 is opened or closed using the operation panel 10, the motor 25 is driven forward or backward through the door control circuit 24, so that the door 9 can be opened or closed.

When leaving the vehicle W from the multi-story parking lot 1, the user operates the driving operation panel 10, calls the desired cage 3 to the parking room 7 on the vehicle entrance floor, and operates the door 9 to open it. do. After that, the vehicle W is taken out from the entrance 8,
As shown in FIGS. 1 and 2, a passing operation corresponding to the closing request pattern is performed from the outside of the entrance/exit 8 toward the passing optical sensor 17 to close the door 9. The procedure for closing the door 9 in this case will be explained based on the flowchart shown in FIG. 6. First, in step S1, the person detector 15 determines whether or not there is a person in the parking space 7, and if a person is detected. Then, the process returns to step S1 again. In the detection state where no person is detected, the process moves to step S2, and in step S2, the car detector 13 further determines whether there is a vehicle W in the parking room 7, and if the vehicle W is detected. Then, the process returns to step S1.

If the vehicle W is not detected by the vehicle detector 13 in step S2 and the vehicle is not in the warehouse, it is determined that the vehicle has left the warehouse, and the process proceeds to step S3.

[0022] In step S3, the headlight 1 of the vehicle W
It is determined whether or not the passing light sensor 17 has received the passing light from 6. If the passing light sensor 17 has not received the passing light, the process returns to step S1. Further, if passing light is received, the process moves to step S4, and in step S4, the passing pattern discriminator 23 determines whether the signal pattern of the passing light is a pattern requesting closing of the door 9. If the signal pattern of the passing light differs from the preset closing request pattern, the process returns to step S1. When the signal pattern by the passing light corresponds to a preset closing request pattern, a door close signal is output to the door control circuit 24, and when the close signal is input to the door control circuit 24, the motor 25 is driven, The door 9 is operated to close (step S5).

Next, in step S6, it is determined whether the closing operation of the door 9 is completed or not, and during the closing operation of the door 9, the human detector 15 is in a safe state, that is, the human detector 15 is in the state of detecting the absence of a person, and the vehicle is not being detected. It is determined whether or not the device 13 maintains the state of detecting that the vehicle W has not entered the warehouse (step S7), and if the state is maintained, the process returns to step S5. Furthermore, if any of the detection states is interrupted, the process moves to step S8, the closing operation of the door 9 is stopped, and conversely, the motor 25 is moved in the direction of opening the door 9.
is driven to open the door 9. After that, the process returns to step S1.

On the other hand, when it is determined in step S6 that the closing operation of the door 9 has been completed, the closing operation of the door 9 of the entrance/exit 8 is completed.

As described above, after the user leaves the parking lot 7 of the multi-story parking lot 1, if the user performs a passing operation corresponding to the closing request pattern from inside the vehicle W, the door 9 will be automatically closed. When the vehicle W leaves the garage, there is no need to get out of the vehicle to close the door 9, which reduces the burden on the user. In addition to mechanical safety confirmation using the vehicle detector 13 and person detector 15, safety can be confirmed once again visually by the user before performing the passing operation to close the door 9. Safety can be improved. Furthermore, since the passing pattern discriminator 23 determines whether the pattern is a closing request pattern, it is possible to effectively prevent the door 9 from being closed due to inadvertent light reception by the passing light sensor 17.

[0026] Furthermore, since the passing function of the headlight 16 that is standard equipment on the vehicle W is used to send a signal for closing the door 9, a special device is separately installed on the vehicle W. It is not necessary and does not cause any financial burden to the user.

The closing request pattern set in the passing pattern discriminator 23 may be any pattern that can clearly be determined to be passing by a person's will, and is not limited to the patterns disclosed in the embodiments. Further, in the embodiment, a vertical circulation type multilevel parking lot 1 is shown, but an elevator type multilevel parking lot or the like may be used.
