DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for detecting a parking violation vehicle applied to a parking violation prevention system, and more particularly, to detecting a parking violation vehicle without using a license plate number recognition by an image processing device. It relates to a device suitable for the case.

[0002]

2. Description of the Related Art As a method of detecting a parking-violating vehicle for eliminating illegal parking or annoying parking, a method of recognizing a vehicle number on a license plate using image processing technology is widely known. For example, JP-A-2-2494 and JP-A-3-29100 disclose vehicle number recognition-related technologies using image processing technology. These recognize the vehicle number of a vehicle parked and stopped in a parking prohibited area on a public road using an image processing device, and specify a parking violation vehicle.

However, in these methods, it is necessary to install an image processing device in each parking prohibition monitoring area, and installation and maintenance costs, cases in which the image processing apparatus cannot be installed in the area, and images taken Many operational issues remain, such as when the vehicle number cannot be recognized from the information.
In Japanese Patent Application Laid-Open No. H8-7192, the use of an electronic still camera solves the above-mentioned problems such as cost and installation location.

However, since the image processing technology is used, there is a problem that the vehicle number cannot be recognized from the photographed image information depending on the dirt or damage condition of the license plate, and the first problem has not yet been solved. Not in.

In recent years, as a technology relating to a license plate with a data carrier, which is embedded in a sealing portion of the license plate, information specific to the vehicle is stored in advance in a data carrier using mobile communication technology, and a system for detecting the data. Japanese Unexamined Patent Publication No. Hei 8-287389,
-282403.

According to this method, (1) the vehicle number and / or the vehicle type, the weight passenger, the displacement, and the model are used as the vehicle-specific information to be given to the data carrier. And quick check of overload detection
I can do it properly.

(2) Even when the license plate is dirty with mud, snow, or the like, the vehicle number can be recognized.

(3) If the data in the data carrier is to be falsified, the seal must be broken, and the data in the data carrier can be prevented from being falsified.

(4) Cost can be reduced.

There are a number of advantages of the data carrier. However, when the license plate with the data carrier itself is replaced by an unauthorized means, there is a problem that it is not possible to correctly recognize the vehicle solid.

As a related technique, Japanese Patent Laid-Open No. 9-198587 discloses a parking violation prevention system capable of efficiently controlling a parking violation. When a parking violation vehicle is detected, the system is coded based on map information. The center station sends the position information of the offending vehicle to the center station, and the center station notifies the police officers near the parking offending vehicle of the position of the offending vehicle in accordance with the position information of the offending vehicle. A parking violation prevention system has been proposed.

[0012]

In recent years, the parking lot infrastructure has been rapidly improved, but has not been able to keep up with the increase in new car registrations. In particular, traffic jams and traffic accidents caused by offending parking vehicles on public roads in urban areas have long been social problems. Basically, it is a priority to develop social infrastructure. (1) Realization of low-cost systemization (2) Location-independent detection method of parking offending vehicles (3) Right and left of license plate image It is hoped that an effective parking violation prevention system, such as a method for recognizing vehicle numbers that will not be used, will be realized early.

However, as described above, in the prior art, (1) improvement of image processing accuracy such as poor reading of a vehicle number due to dirt or damage of a license plate, cost problem (introduction / maintenance), and coping with places where installation is impossible. However, technical issues such as the problem of a sophisticated license plate tampering vehicle remain.

An object of the present invention is to detect a parking violation vehicle in a parking violation prevention system at low cost without depending on a place and without depending on a license plate. It is still another object of the present invention to provide a parking violation vehicle detection device that is robust against unauthorized alteration of a license plate.

[0019] With this configuration, by the operation of the parking violation detecting device by the enforcement officer in the parking prohibited area, the vehicle-specific IC tag mounted on the vehicle parked in the parking prohibited area can be used. The car name and car number, which are the identification information, are taken in via the inquiry means. The retrieved car name and car number are searched for parking violation candidate information stored in the storage means of the device by the parking violation detecting means of the device, and it is first confirmed whether or not the vehicle is a newly parked vehicle. .
In the case of new parking, the vehicle name, the vehicle number, and the current time are stored as parking violation candidate information together with the own position information from the position detection device, and are prepared for the next enforcement timing.

If the input car name and car number have already been registered in the parking violation candidate information, then the parking position is confirmed, and whether or not the same vehicle is to be continuously parked is determined by the registered parking position, Whether or not the newly input position information this time is a deviation amount within an allowable range is determined by checking using a parking position calculation constant stored in advance.

After it is determined that the same vehicle is continuously parked, it is determined whether or not the elapsed parking time from the start of parking to the present time exceeds the allowable parking violation time, and exceeds the allowable parking violation time. In this case, the parking violation of the vehicle is determined, and the parking violation information of the vehicle is displayed on the display means of the parking violation detection device.

Have been. The parking prohibition place constant C1, the parking violation candidate information M1, and the parking violation confirmation information M2 are secured in the storage device of the portable terminal device 1, but are stored in an external storage device such as a memory card. You may make it do.

The interrogation device 12 reads the vehicle name 21 and the chassis number 22 stored in the IC tag 2 mounted on the vehicle by operating the operation device 11, respectively, and reads the parking violation detection device 1
3 enters and uses it. The position detecting device 14 is, for example, a GPS system using a satellite and has its own position information 14.
1 can be measured and used by the parking violation detection control unit 13 to obtain the position of the parked vehicle from the operation position of the mobile terminal device 1.

The self-location information 14 is stored in the parking prohibition place constant C1.
From 1 are stored constants for enabling continuous parking recognition of the same vehicle and automatically recognizing a place name of a parking prohibition area. The parking violation candidate information M1 stores the parking start time, the vehicle name, the chassis number, the vehicle position information, and the like as the parking violation candidate at the timing when the parking start of the vehicle parked in the parking prohibited area is detected. It is for. Here, registration in the parking violation candidate information M1 is performed only when the parking violation candidate information M1 and parking violation determination information M2 have not been registered.

The parking violation determination information M2 is for storing information on the vehicle whose parking violation has been determined in the parking prohibited area, and includes information on the transcription of parking violation candidate information and vehicle inspection information. I have. The method of generating the vehicle inspection information will be described later in connection with the headquarters center system 3.

The communication control device 15 is provided as communication means for various information retrieval of the head office center system 3. The display device 16 uses the parking violation candidate information M1 and the parking violation determination information M2 to display the parking violation vehicle detection status of the parking prohibited area including the determined and unconfirmed states, and is provided with a diagram described later. FIG. 17 shows an example of a display screen displayed on the display device 16.

Although the headquarters center system 3 has many functions other than those shown in the drawings, only the minimum functions necessary for the present invention will be described. It has a configuration of a vehicle inspection information database F1. The communication control device 31 is for receiving a database search request from the mobile terminal device 1. Upon receiving the database search request, the search device 2
2 is the search key of the request, the terminal ID and the car name 21
A search for database information is executed using the vehicle chassis 22.

The search device 32 is a search execution device for various types of database information. The search device 32 may be a high-performance general-purpose computer to a database search-dedicated computer, depending on the amount of data to be stored, or depending on the importance of responsiveness, or , From a high-performance server to a general-purpose personal computer, if necessary. The search result by the search device 32 is transmitted to the mobile terminal device 1 via the communication control device 31.

The vehicle inspection information database F1 is a database of vehicle inspection certificate information, and stores information used for the vehicle inspection certificate. In this embodiment, the search key of the database is the vehicle name 21, the chassis number 2
Although the number is 2, it is not limited to the vehicle name 21 and the chassis number 22, but should be given flexibility so that various search keys can be used.

Next, the parking violation detection control unit 13, which is a feature of the present invention, will be described with reference to the data configuration diagrams of FIGS. 2 to 10 and the flowcharts of FIGS. 11 to 16.

FIG. 2 shows a schematic configuration of the parking violation candidate information M1, FIG. 3 shows a detailed configuration of parking information in the parking violation candidate information M1, and FIG. 4 shows details of vehicle inspection information in the parking violation candidate information M1. 2 shows a configuration.

In FIG. 2, the parking violation candidate information M1 is
M1 is composed of parking information M11 and vehicle inspection information M12.
1 manages from the new parking in the parking prohibition zone to the detection of a parking violation determination, and the vehicle inspection information M12 manages information equivalent to an automobile inspection certificate of the vehicle. The parking information M11 is a vehicle name M111 and a chassis number M112 as shown in FIG. 3, which are identification information unique to the vehicle. The data corresponds to the vehicle name 21 and the chassis number 22 which are the vehicle-specific identification information read from the vehicle-mounted IC tag 2 and is important data for vehicle identification.

In the present invention, the vehicle name 21 and the chassis number 22
Thus, any vehicle can be an identifier that can identify the vehicle. The vehicle name M111 may be Japanese characters or alphanumeric characters. Usually, the name of the manufacturer of the vehicle is used, but this is not a limitation. Basically, any data that guarantees the uniqueness described above may be used. Further, as the chassis number M112, a model number + serial number of the vehicle is usually used as a production management number of the manufacturer, and can be data that guarantees uniqueness in vehicle solid management.

The parking place M113 indicates the name of a no-parking area where the enforcement of parking violations is carried out. The parking area M113 is filled with Japanese or alphanumeric characters and symbols, and is displayed to the enforcement officer via the display device 16. It is intended to be used for providing information. Parking position north latitude M114 and parking position east longitude 1
Reference numeral 15 denotes own position information 14 acquired from the position detecting device 14.
1 and the parking position information when a newly parked vehicle is detected is stored as north latitude AA degrees BB and east longitude XX degrees YY. The parking start time M116 is a time when the newly parked vehicle is detected as a parking start time.

The vehicle inspection information M12 includes a vehicle number M121 and a search request result to the headquarters center system 3 as shown in FIG. It is composed of The vehicle number M121 is well-known data displayed on a so-called license plate, and includes a land transportation office M1211, a vehicle type M1212, a use M1213, and a serial number M1214.

By the way, the parking information M11 is created as candidate information for the vehicle at the start of detection of a vehicle violating the parking in the no-parking area, and the erasure is transcribed to the parking violation determination information M2 by specifying the parking violation of the vehicle. At the time or when the parking violation detection control unit 13 recognizes that another new vehicle is parked at the parking position of the vehicle, the vehicle inspection information M1
2 is also deleted. Vehicle inspection information M
12 is composed of the same search key of the vehicle name M111 and the vehicle number M112.

The erasure timing of the parking violation candidate information M1 is performed as follows.

In the parking prohibition area, basically, a stop within the permissible parking violation time period is allowed, so that the status of the parked / stopped vehicle usually changes every moment. Therefore, when the detection of a parking-violating vehicle by the mobile terminal device 1 is repeatedly started each time the police officer makes a patrol, vehicle information that is not already parked is accumulated more and more.

Therefore, the erasure timing of the parking violation candidate information M1 is determined by the vehicle name 21 and the vehicle name 21 read from the IC tag 2 of the vehicle when the enforcement operation of the parking violation vehicle is performed using the portable terminal device 1 by the enforcement officer. Even if the vehicle number 22 is present in the parking violation candidate information M1, the self-position information 141 newly input from the position detection device 14 of the mobile terminal device 1 and the registered measurement position information are out of a predetermined value range. In this case, it is considered that the parking position is different due to reparking after moving, and the parking position north latitude M114, parking position east longitude M115 and parking start time M116 of the registered parking violation candidate information M1 are replaced with the latest information. I do.

Even if the same vehicle name 21 and chassis number 22 do not exist, the self-position information 141 that has been input most recently, the registered parking position north latitude M114 and the parking position east longitude M11
When 5 is within the predetermined range, the new registration processing is performed after the corresponding registered information of the parking violation candidate information M1 is deleted.

On the other hand, the erasure timing of the parking violation determination information M2 is basically such that when the enforcement of the parking violation processing procedure by the enforcement officer is completed, the parking violation determination information processing for the vehicle concerned is carried out using At the timing input from the terminal device 1, the information of the parking violation determination information M2 is deleted. Here, although not specifically illustrated in the present embodiment,
A method is also conceivable in which the erasure information is recorded as history information in a log file, and when a past situation is required or when it becomes necessary to restore information, it is easy to cope with the situation.

FIG. 5 shows a schematic structure of the parking error determination information M2, FIG. 6 shows a detailed configuration of the parking violation determination information M21, and FIG. 7 shows a detailed configuration of the vehicle inspection information M22. FIG.
The difference between the parking violation candidate information M1 in FIG. 4 and the parking violation determination information M2 in FIG. 5 to FIG. 7 is that the parking violation candidate information M1 covers the process from new parking to the detection of parking violation, while the parking violation determination information M2 is From the detection of the parking violation to the completion of the enforcement procedure by the enforcement officer, the data life differs for the above-mentioned purpose, but since the data configuration is the same, FIG.
6 will be omitted.

FIG. 8 shows a schematic configuration of the parking prohibition place constant C1. In FIG. 8, the parking prohibition location constant C1 includes a location constant C11 defining a parking prohibition area and a parking position calculation constant C12 of a vehicle parked in the parking prohibition area.

FIG. 9 shows the definition contents of the place constant C11 that defines the parking prohibited area.

In FIG. 9, a location constant C11 is a Name indicating a location name and a (E) indicating an east longitude and a north latitude of location information.

d (E2, N2) coordinates 4 points and w (OO) indicating the bandwidth
Degrees ×× minutes) as a constant.

When the parking prohibited area is recognized from the position detecting device 14 using the own position information 141, if the east longitude data of the own position information 141 is Ex and the north latitude data is Ny, then a (E1 , N1), b (E2, N
1), coordinates 4 of c (E1, N21) and d (E2, N2)
If the position (Ex, Ny) is searched using the point and h (OO degrees xx minutes) indicating the band width, it is possible to determine whether or not the area corresponds to the area, and the place name can be automatically recognized.

FIG. 10 shows the definition of the parking position calculation constant C12 of the vehicle parked in the parking prohibited area. In FIG. 10, C12 indicates the error range of the measurement point ±
These are stored as ΔE and ± ΔN. Whether the vehicle parked in the no-parking zone is a parking-continuous vehicle is determined by first determining whether the vehicle is already parked and the positions of the initial measurement positions (E0, N0) and (± ΔE, ± ΔN). The determination can be made by measuring the parking position of the vehicle based on the error.

FIG. 11 shows a vehicle inspection information database F1.
FIG. 1 shows a database configuration diagram. In FIG. 11, a vehicle inspection information database F1 includes a vehicle information F11 which is identification information unique to the vehicle, a vehicle number F12, and an expiration date F1 which is a date when the expiration date of the automobile inspection certificate expires.

Is composed of a vehicle name F111 and a chassis number F112, and this is a search key of the database F1. Vehicle number F12
Consists of well-known data displayed on the above-mentioned license plate.

FIGS. 12 to 17 show the parking violation detection control unit 1.
3 is a detailed illustration of the processing description using a flowchart.

In FIG. 12, the parking violation detection control unit 13
0 describes the process in detail, and the description supplements the flowchart. Step 131 is the input of the vehicle name 21 and the chassis number 22 of the vehicle. Step 132 is input of position information 141 which is an operation position of the mobile terminal device 1 by the control pipe. Step 1
33 means that the situation of the parked vehicle is determined from the input data, that is, in the case of new parking required for the determination in step 134, when the same vehicle changes the parking place and is parked again in the same parking prohibited area, In addition, it is necessary to separate continuous parking or the like of the same vehicle at the same place, which is a target of a parking violation vehicle.

The definition of the newly parked vehicle is that the vehicle name 21 and the chassis number 22 are not registered in the parking violation candidate information M1. When the same vehicle changes the parking place within the parking violation allowable time and parks again in the same parking prohibited area, the parking violation candidate information M1 is registered when the relevant vehicle name 21 and the chassis number 22 are registered. The parking position north latitude M133 and the parking position east longitude M134 corresponding to the first measurement position (E0, N0) of the candidate information M1 are the parking position calculation constant C12.
(± ΔE, ± ΔN). That is, it is determined that the vehicle is not parked at the first measurement position (E0, N0) and has been reparked at another different position.

The target of the parking violation vehicle is that the vehicle name 21 and the chassis number 22 are registered in the parking violation candidate information M1, and the first measurement position (E) of the parking violation candidate information M1 is registered.
(0, N0), the parking location north latitude M133 and the parking location east longitude M134 are (± Δ) of the parking position calculation constant C12.
E, ± ΔN).

The process of deleting the absent vehicle in step 137 is as follows.
In new parking, it was found that the parking position was a position where vehicle parking occurred within the parking violation allowable time, or that the same vehicle changed the parking place and parked again in the same parking prohibited area In some cases, it is necessary post-processing. Unless this post-processing is performed, it is to prevent the above-mentioned vehicle information that has not been parked from being accumulated more and more.

Next, FIG. 13 shows the case of new parking, FIG. 14 if the parking location of the same vehicle is changed, and FIG. 15 if the continuous parking at the same location. Will be described with reference to a flowchart.

FIG. 13 shows the registration processing 135 of a newly parked vehicle in the case of new parking using a flowchart in detail.

In FIG. 13, the parking start time input processing in step 1351 is an internal clock held by the central processing unit used in the parking violation detecting device 13, and fetches year, month, day, character, minute and second as necessary. . The registration in step 1352 is for the parking violation candidate information M1, and the vehicle name M211 and the vehicle number M212, the parking place M213,
The parking position north latitude M214, the parking position east longitude M215, and the parking start time M216 are registered as registration data at predetermined positions of the parking violation candidate information M1.

In step 1353, the registration information obtained by adding the terminal ID assigned to each portable terminal device in advance to the head of the vehicle name M 211 and the chassis number M 212 in the registration information via the communication control device 15 is transmitted to the head office. It is transmitted to the center system 3.

FIG. 14 is a flowchart showing details of the parking location change processing 136 for the same vehicle when continuous parking is performed at the same location. Steps 1361 and 1363 correspond to step 1 described above.
351 and step 1353 are not described here. A step 1362 replaces the parking position north latitude M114, the parking position east longitude M115 and the parking start time M116 of the parking violation candidate information M1 with the latest information.

FIG. 15 is a flowchart showing details of the parking violation determination processing 138 when continuous parking is performed at the same place.

In FIG. 15, step 1381 is a calculation process for calculating the parking time from the current time difference from the parking start time M116 of the vehicle in the parking violation candidate information M1. In step 1382, it is determined whether or not the vehicle is a parking violation vehicle based on a predetermined allowable parking time for determining a parking violation and the parking time. When it is determined that the parking violation has been caused, one record of the parking violation candidate information M1 is registered as the parking violation determination information M2.

The meaning of the movement registration is to delete the record information of the parking violation candidate information M1 after registering the record information of the parking violation candidate information M1 at a predetermined position of the parking violation determination information M2. A step 1384 activates parking violation confirmation display processing to display parking violation confirmation information on the display device 16 of the portable terminal device 1, and displays a display screen PIC18 as shown in FIG.

FIG. 16 shows that the headquarters center system 3
This is a detailed description of a process performed when a search request result is notified using a flowchart. Step 139
Then, the vehicle inspection information, which is the received search request result, is stored in the vehicle inspection information area of the parking violation candidate information M1 or the parking violation determination information M2. Naturally, error processing such as the absence of the key of the corresponding vehicle name and chassis number is required.

FIG. 17 describes in detail the vehicle inspection information database search processing in the search device 32 in the headquarters center system 3 using a flowchart. The search process is executed in each of steps 320 to 322. Naturally, error processing such as the absence of the key of the corresponding vehicle name and chassis number is required.

In the above description, only the vehicle inspection information database is used. However, if it can be retrieved from vehicle-specific identification information such as a vehicle name and a chassis number, a parking violation regular vehicle / person, an emergency / The system should be able to provide related information as needed, such as past arranged vehicles, storage locations of vehicles, owners, and the like.

FIG. 18 shows a display example of the status of a parking offending vehicle displayed on the display device 16.

In FIG. 18, a PIC 18 is an example of a screen display. As a whole, a display of the current time, a place name of the parking prohibited area, information on a vehicle violating the parking in the parking prohibited area, information on a parked vehicle, and the like are shown. It is what is displayed.

T1 and T2 indicate a title part for guidance, and D1 displays the name of the parking prohibited place automatically determined by the parking violation detection control unit 13. The screen also displays the current time D2.

Next, D3 and D4 of the screen display example will be described. Line D3 includes a vehicle number, which is information written on a license plate, with “*” indicating parking violation confirmed,
