Abstract

PROBLEM TO BE SOLVED: To improve security as a parking lot by opening the gate of an entrance and making a vehicle enter only when a number which is read at the parking lot entrance is matched with a number which is previously registered as a contracted vehicle. SOLUTION: The entrance 1 of the toll parking lot by the month or by the year, the exit 2 of the parking lot, the gate 3a of the entrance 1 and the gate 3b of the exit are provided. When the vehicle 5 which is to enter stops at a position where sensors SI1 and SI2 are turned on, a vehicle number reader 4 automatically reads the number of the vehicle which is to enter, and the read signal is sent to a controller 6. The controller 6 opens the gate 3a of the entrance when the number which is read is matched with the registered number. When the vehicle which is to leave stops at a position where two sensors SO1 and SO2 are turned on, the gate 3b of the exit opens and it can leave. Thus, the number of the contracted vehicle can be automatically recognized and the vehicle is caused to enter the parking lot.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a parking lot system used for, for example, monthly or yearly contract vehicles.

[0002]

2. Description of the Related Art Conventionally, in monthly parking lots that have been installed in condominiums, etc., use the magnetic card distributed by the owner of the parking lot to the contractor to open the entrance gate and enter the parking lot. Was there.

[0003]

However, in a parking lot of such a system, anyone can enter the parking lot regardless of the number of the car as long as he has the above magnetic card. Therefore, it is possible to park a car that is not a contract car. Therefore, there is a possibility that there may be a trouble between an authorized contractor and a person who illegally enters a parking lot by using another person's card, and improvement is desired. Also, even if you replace the car described in the contract with a new car, you can practically use the parking lot as long as you have the card, not the original parking lot management that parks the contract car .

The present invention solves the above-mentioned conventional problems, and proposes a parking lot system in which the number of a contracted vehicle is automatically confirmed and the vehicle is entered into a parking lot.

[0005]

Means for Solving the Problems In the first invention,
A reading device for reading the number of the contract car is installed at the entrance of the parking lot, and only when the read number matches the number recorded in advance as the contract car, the entrance gate is opened to enter the car.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. First, the reading of the vehicle number will be described. For reading the vehicle number, see Mitsubishi Electric Technical Report VOL. 62 · NO. 2 ・ 1988, P9 ~ P12
"License plate recognition technology" or Hitachi review / VO
L. 76. NO. 3, P15 to P20 "Image recognition technology that supports the sophistication of road traffic systems" and the like. That is, according to the above-mentioned Mitsubishi Electric Technical Report, the license plate includes a large plate for a large vehicle and a medium plate for a medium vehicle, and the size, character arrangement, etc. are standardized as shown in FIG. ing. The letters on the license plate are “Land Support Code”, “Vehicle Code”, “Application Code”,
It consists of a "serial number", and the land support and vehicle type code are collectively referred to as the upper character, and the application code and the serial number are collectively referred to as the lower character. Some license plates actually mounted on automobiles are bent or discolored, and it is indispensable for image processing to support them.

Next, the flow of character recognition processing of the license plate will be described with reference to FIG. This process can be roughly divided into the following four steps. (1) License plate display and lower character cutout License plate extraction and lower character cutout are performed from the captured image using the shape of the license plate and the character arrangement in the plate surface shown in FIG. 1 as keys. (2) Upper character cut out From the extracted license plate, the land support code position,
Decide the vehicle type code position by one character at a time. (3) Character recognition Recognize the land support code, vehicle type code, application code, and serial number cut out one by one by pattern matching. (4) Comprehensive Judgment The recognition result is comprehensively judged using the information peculiar to the license plate and used as recognition information.

The license plate is recognized by performing such a process, but this description intends to use the license plate thus recognized for managing monthly or yearly paid parking lots. , Which will be described step by step below.

FIG. 3 shows the first embodiment of the present invention, in which 1 is an entrance of a monthly or yearly pay parking lot,
2 is an exit of a parking lot, 3a is a gate of an entrance 1, 3b is a gate of an exit 2, 4 is a car 5 which is provided at the entrance and is about to enter
Is a device for automatically reading the number of the car that is about to enter when the sensors SI1 and SI2 are both turned on, and the read signal is given to the controller 6. SO1 and SO2 are two sensors provided at the exit 2, and the vehicle 7 that is about to leave is the two sensors S
The gate 3b at the exit can be opened and exited by stopping at a position where both O1 and SO2 are ON. In the pay parking lot, the parking space for each contract vehicle is always decided, and it is not possible to park in the parking space for other vehicles.

FIG. 4 is a diagram showing a main part of the controller 6, and 8 is a storage device in which all the numbers of the contracted vehicles are recorded, and the numbers of the contracted vehicles are recorded in association with the parking space. ing. Reference numeral 9 is a search means for scanning a plurality of recorded numbers. Reference numeral 10 is a judging means for collating the number read by the number reading device 4 with the number searched by the searching means 9, and if they match, outputting a signal 11 for opening the gate 3a at the entrance. Reference numeral 12 denotes an exit gate control means for opening the exit gate 3b, which outputs a signal 13 for opening the gate 3b when both of the two sensors SO1 and SO2 at the exit are turned on.

FIG. 5 is a flow chart showing a series of these operations.

In the above embodiment, two sensors S are provided at the entrance and the exit, each of which has a predetermined interval in the vehicle length direction.
I1, SI2, SO1 and SO2 are provided, but the relative positional relationship between the car and the number reading device is very important because the number must be read accurately at the entrance, but at the exit it is the departure Since it suffices to detect that the vehicle to be approached approaches the exit gate, both SO1 and SO2 are not necessarily required, and only one vehicle may be used.

In the first embodiment, the main constituent elements are shown as independent block configurations, but it goes without saying that these hardware can be replaced with the functions of a computer.

[0014]

As described above, according to the present invention, only the contracted vehicle can be parked, so that the security of the parking lot can be enhanced. In addition, even if you use another person's card, you cannot enter unless you have a registered number of cars, so you can prevent troubles in the parking lot.
