Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot guidance system for general vehicles.

[0002]

2. Description of the Related Art In recent years, people's vehicle ownership rate has increased, and vehicles have become an indispensable means of transportation in daily life. Therefore, it is indispensable to install a parking lot in a place where a large number of vehicles are gathered, such as a large store or in front of a station, and labor saving and efficiency improvement in its operation are required. Most parking lots have an entrance gate and an exit gate that detect the passage of vehicles, but there are few systems that automatically guide the entered vehicles.

FIG. 5 is a plan view showing the structure of a typical conventional parking lot. The vehicle entrance gate 1 of the parking lot is provided with first vehicle passage detectors 2 and 3. The vehicle passage detector 2 includes a light emitting device 2a and a light receiving device 2b.
Irradiation light from the light emitting device 2a is blocked by the passing vehicle V, the light receiving device 2b outputs a signal, and the signal is transmitted to a controller described later. The vehicle passage detector 3 also has the same light emitting device 3a and light receiving device 3b as the vehicle passage detector 2, and is installed at an appropriate distance from the vehicle passage detector 2. Therefore, when the signals are output from the light receiving devices 2b and 3b in this order, the controller identifies that the vehicle V has entered the storage gate 1.

On the other hand, the parking lot 4 is a space for parking each vehicle passing through the entrance gate 1, and a plurality of parking spaces 5 are provided.
a, 5b ... An exit gate 6 is provided at the exit of the parking lot 4, and second vehicle passage detectors 7 and 8 having a light emitting device and a light receiving device similar to the vehicle passage detectors 2 and 3 are attached. When the light receiving devices 7b and 8b detect the irradiation light from the light emitting devices 7a and 8a in this order, the controller 9 detects the leaving of the vehicle. The controller 9 processes the signals from the vehicle passage detectors 2, 3, 7, and 8,
The number of vehicles parked in the parking lot 4 is managed, and the display section provided at the entrance gate 1 displays full or empty vehicles.

In order to guide the vehicle V entering from the entrance gate 1 in the thus constructed parking lot, the guide member P
Finds an empty parking space and guides the vehicle V to the empty parking space each time.

[0006]

However, in such a conventional vehicle guidance method, since each vehicle V entering the parking lot is guided to the designated parking spaces 5a, 5b ... Is required. When the number of parked vehicles is small, the guide P does not have to be present, but the number of parking spaces 5 is large, and guidance work for the guide P is important for managing a large-scale parking lot that is almost full.

The present invention has been made in view of the above-mentioned conventional problems, and realizes a parking lot guidance system for unmanning the vehicle guidance in the parking lot, thereby omitting it and improving efficiency. With the goal.

[0008]

SUMMARY OF THE INVENTION The present invention is a parking lot guidance system for a parking lot having an entrance gate, a parking lot including a plurality of parking spaces, an exit gate, and a controller for managing each gate and a vehicle in the parking space. And a first vehicle passage detector for detecting entry of a vehicle into the entrance gate, a second vehicle passage detector for detecting exit of the vehicle from the exit gate, and a vehicle for detecting the presence or absence of a vehicle in each parking space. A presence detector, a first guidance indicator light installed at the entrance side of each parking space and lit when the vehicle can be parked, and a second guidance provided in the aisle of the parking lot and instructing the progress of the parked vehicle. An indicator light, and the controller includes a first and a second
The number of parked vehicles in the parking lot is counted by the output signal of the vehicle passage detector, and the number of parked vehicles is also stored by the signal of the vehicle presence detector. Based on the data of 1st and 2nd in order to park the vehicle in the empty parking space,
And a parking space designating means for turning on the guide indicator light.

[0009]

According to the present invention having such characteristics, in order to park the vehicle in the parking lot, when the vehicle enters the entrance gate, the first vehicle passage detector sends a signal to the controller. The parking number counting storage means stores the presence / absence of a vehicle in each parking space in the storage status management memory in response to a signal from the vehicle presence detector, and stores an empty parking space. Then, if parking is possible, the parking space designating means blinks the first guidance indicator light at the empty position and turns on the second guidance indicator light. The driver of the vehicle moves the vehicle according to these guide lights to park the vehicle in a designated parking space. Similar instructions are given to vehicles that are subsequently stored, and the vehicles are guided to empty spaces in a specific order. When the vehicle exits from the exit gate, the parking number counting storage means updates the number of vehicles existing in the parking lot by the signal of the second vehicle passage detector. In this way, a large number of vehicles can be guided unmanned and efficiently to the parking space.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A parking lot guidance system according to an embodiment of the present invention will be described with reference to FIG. In this figure, a parking gate is provided with an entrance gate 1 and an exit gate 6, respectively. The entrance gate 1 has a first vehicle passage detector 2,
3 and that the exit gate 6 is provided with the second vehicle passage detectors 7 and 8 as in the conventional example, and detailed description thereof will be omitted.

The parking lot 10 is provided with parking spaces 11a, 11b ... 11n for storing the respective vehicles V.
Parking spaces 11a, 11b, parking spaces 11c, 11d, so as to face the central passage 12 of the parking lot 10 ,.
-Parking spaces 11n-1 and 11n are arranged respectively. Unlike the conventional example, each parking space 11a ... 11
The vehicle presence detectors 13 are provided at positions on both sides of the vehicle.
a, 13b ... 13n are installed. The vehicle presence detector 13 has a light emitting device and a light receiving device similarly to the vehicle passage detectors 2, 3, 7, and 8, and detects the presence or absence of a parked vehicle by the light emitted from the light emitting device.

Next, parking spaces 11a, 11b ... 1
At the entrance of 1n, the first guidance indicator lights 14a, 14b ...
14n are provided. The guide indicator light 14 is a display unit installed on the floor or ceiling and blinks when the parking space is empty to notify the driver of the location. The passage 12 is also provided with a second guidance indicator light 15. The guide indicator light 15 is a guide indicator light that is provided on the floor surface or the ceiling and indicates the progress of the vehicle by lighting an arrow mark.

The vehicle passage detectors 2, 3, 7, as described above,
8 and the vehicle presence detector 13 and the guide indicators 14 and 15 are connected to the controller 16, respectively. Controller 1
A control unit 6 counts the number of parking spaces in the parking lot 10 and guides the parked vehicles to the parking spaces 11. The controller 16 is composed of a parking number counting storage means 16a and a parking space designating means 16b. The parking number counting storage means 16a processes the signals of the vehicle passage detectors 2 and 3,
While counting the number of vehicles entering, processing the signals of the vehicle passage detectors 7 and 8, counting the number of vehicles leaving, the current total number of parked vehicles is stored. Further, the parking number counting storage means 16a outputs the state of full or empty to the display unit. The parking space designating means 16b identifies the parking space 11 of an empty vehicle so as to store the vehicle V that has entered from the storage gate 1 in the designated parking space 11, and turns on the guide indicators 14 and 15 to advance the vehicle. It gives instructions and guides the approaching vehicle.

The operation of the parking lot guidance system configured as described above will be described with reference to the flowcharts of FIGS. 2 and 3 are flowcharts showing the operation procedure of the controller 16. Currently, as shown in FIG. 1, for example, vehicles are stored in parking spaces 11b and 11d,
Suppose another parking space is empty. As shown in FIG. 4, the parking number counting storage means 16a has a storage status management memory, and stores the storage status of each parking space 11 respectively.

When the controller 16 starts operating and the vehicle V enters from the entrance gate 1, the vehicle passage detectors 2 and 3 detect the passage of the vehicle in step 21. And step 2
Proceeding to 2, the controller 16 collates the storage status management memory. First, in step 23, it is checked whether or not the first parking space 11a is empty. If the first parking space 11a is empty, the controller 16 permits the parking lot 10 to be stored and turns on the guide indicator lights 15 and 14a, respectively. Next step 25
Then, the vehicle presence detector 13a detects the presence / absence of the vehicle V, and if there is no vehicle in the parking space 11a, the process returns to step 24, and the guidance indicator lights 15 and 14a are continuously lit.

When the vehicle presence detector 13a detects the vehicle V, the routine proceeds to step 26, where the guide indicators 14a and 15 are turned off. At this time, in step 27, the controller 16 writes "1" in the parking space 11a in which the vehicle is parked in the storage status management memory.

Next, when another vehicle enters, step 21
To 23, the parking spaces are checked. Since the vehicle is present in the parking space 11a in step 23, the process proceeds to step 28, and it is checked whether or not the parking space 11b is parked. If the vehicle is empty, the vehicle is guided to this space as in steps 24 to 27 (routine 29). As shown in FIG. 4, when “1” is registered in the warehousing status management memory, it is determined that the vehicle is not empty, and the process proceeds to the next step 30. If the parking space 11c is empty, step 24
The guide indicators 15 and 14c are turned on in the same procedure as in steps 27 to 27 to guide the vehicle to the parking space 11c (routine 31).

When the last parking space 11n is full, the routine proceeds from step 32 to step 34, where the controller 16 displays full on the display. Also, step 27 and routine 2
Each time "1" is stored in the storage status management memory at 9, 31, ..., 33, the process proceeds to step 35, and the number N of vehicles in the parking lot 10 is incremented.

Next, the operation when the vehicle leaves the delivery gate 6 will be described with reference to the flowchart of FIG. When the vehicle detectors 7 and 8 each detect a vehicle in step 41, the signal of the vehicle presence detector 13 of each parking space 11 is identified and the parking space 11 replaced with the empty vehicle is confirmed. Then, in step 42, the controller 16
The contents of the receipt status management memory are updated with these data. Next, in step 43, the number of vehicles entering the warehouse is subtracted. Here, when there is one or more empty parking spaces 11, the process proceeds to step 44, and the display of the full vehicle output to the display unit is canceled. If the vehicle does not exit from the exit gate 6 in step 41 or the parking lot 10 is not full, the process returns to step 21 to wait for the next incoming vehicle.

As described above, the controller 16 has a program for sequentially parking the vehicles in the parking space 11 near the exit gate. Here, the controller 16 executes steps 21, 22, 27, 35, 42, 4
3, the number of parked vehicles in the parking lot 10 is counted by the output signals of the first vehicle passage detectors 2 and 3 and the second vehicle passage detectors 7 and 8, and each parking is performed by the signal of the vehicle presence detector 13. It constitutes the function of the parking number counting storage means 16a that stores whether or not the space 11 is parked. The controller 16 also executes steps 23 to 26 and routines 29 and 3.
1 and 33 and steps 34 and 44, the vehicles are parked in the empty parking space 11 in a specific order based on the data of the parking number counting storage means 16a.
It constitutes the function of the parking space designating means 16 for turning on the first guidance indicator light 14 and the second guidance indicator light 15.

The vehicle is not parked in the parking space 11 designated by the controller 16, and the parking space 1 not designated
When the vehicle is parked at No. 1, the controller 16 stops the lighting of the guide lights 14 and 15 and stores the position of the parking space 11 actually stored.

When the above vehicle guidance method is used, the controller 16 can identify an empty parking space and guide the user of the parking lot unmanned to the designated position using the guidance indicator lights 14 and 15. You can Particularly in a large-scale parking lot, it is extremely difficult for a user to find an empty parking space from a distance, and the trouble of finding an empty space is eliminated. Therefore, the following approaching vehicle is not annoyed, and the vehicle can be stored at the specified position simply by moving the vehicle V forward in accordance with the lighting of the guide indicators 14 and 15.

[0023]

As described above in detail, according to the present invention, the parking condition of the parking lot can be automatically detected by providing the vehicle presence detector in each parking space. Therefore, when the vehicle enters the parking lot, the vehicle can be guided unmanned to the empty parking space. That is, the work of guiding the vehicles in the parking lot is automated, and each vehicle can be sequentially guided and guided to a specific position without obstructing the entry of the vehicles that are subsequently stored. Therefore, an effect that an unmanned parking lot with a short storage time can be realized can be obtained.
