Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection system which is installed at, for example, a tollgate on a toll road and collects a toll according to the type of the vehicle (automobile) coming in. The present invention relates to a vehicle detection device that detects an incoming vehicle for each vehicle.

[0002]

2. Description of the Related Art For example, in collecting tolls on toll roads, for the purpose of auditing and ensuring proper operation of each device,
Accurate grasping and counting of each passing vehicle are required. In order to cope with such a purpose, a vehicle detection device is usually installed at a toll gate of each tollgate.

[0003] This type of vehicle detection device is mainly installed at opposing positions of a plurality of pairs of light emitting and receiving devices on a passage.
A vehicle separator that detects shielding information by vehicles passing between them, and a tread plate that is embedded on a traffic road surface on a line facing the vehicle separator and that detects the number of axes of vehicles passing therethrough, In the detection method, the vehicle is recognized as a vehicle when the vehicle separator is shielded and an appropriate pressure is applied to the tread plate by the wheels. Then, when the shielding of the vehicle separator is released, the passage of the vehicle is detected.

[0004] The vehicle detection device described above properly detects each passing vehicle one by one, and the toll collection device notified of this detection information counts the number of vehicles per work,
It is used as a permission signal for issuing a toll ticket.

[0005] In an automated lane at the entrance where the entrance is automated, the automatic issuance of a passport is automatically performed by a passport issuing device. In addition to the detection signal for each vehicle, information on the vehicle type classification is required. Therefore, in order to determine the type of vehicle (vehicle type) based on the vehicle detection device, the width of each passing vehicle (hereinafter also referred to as tread). Also, a tread that can detect the tire width is prepared.

In the present invention, a vehicle detecting device (vehicle type discriminating device) capable of discriminating the above vehicle type is referred to as a vehicle detecting device. In order to identify a vehicle type, usually, in addition to the above-described vehicle separator and tread plate, an IT for detecting information on a number plate of the vehicle is used.
Imaging means such as a V camera, an image processing device for processing images obtained by the imaging means, a vehicle height detection device for detecting the height of the vehicle,
A vehicle length detecting device for detecting the length of the vehicle is also installed.

[0007]

However, in the above-described vehicle detection device, a plurality of vehicles travels side by side (hereinafter, referred to as a vehicle).
In such a case, the vehicle is recognized as one vehicle. Therefore, the automatic toll ticket issuing device is used for the vehicle 1
Passenger tickets are issued on the basis of detection signals for each vehicle, so in the automated lane at the entrance, the issuance of passports from the automatic passport issuing device is insufficient, and it will occur for the first time upon user notification. There was an inconvenience that the tollgate staff would know the situation.

On the manned entrance lane, issuance of unnecessary toll tickets is to be prevented from the viewpoint of fraud prevention, and a detection signal for each vehicle is transmitted to a toll collection device at the entrance operated by a staff member. For the first time, issuance of a passport is allowed, and since information on translation can not be notified, it is necessary to perform operations that are separately recorded and issue a special passport However, the audit information was ambiguous because the reason for the occurrence was not accurately grasped on the machine processing.

In the manned lane at the exit, the toll ticket issued at the entrance is read by the toll collection device at the exit, the toll is calculated based on the information on the toll gate, and the attendant collects the toll. . In this process, it is necessary to grasp the number of passing vehicles and the number of vehicles processed.However, due to the above-described translation of the vehicle, there is a difference between the number processed by the pass ticket and the number detected by the vehicle detection device, An audit problem occurred.

FIG. 2 shows a configuration of the vehicle detection device 5 and the toll collection device 7 installed in the manned lane 1 at the entrance.
That is, in the vehicle detection device 5, the light projector 8a, the light receiver 8b, and the tread plate 9 are connected to the control unit 31.
The storage unit 32 and the power supply unit 33 are connected to the control unit 31. The storage unit 32 stores, for example, a tread pattern of a specific vehicle such as an automobile with a side wheel or a towing vehicle for towing a vehicle having a significantly different width.

It should be noted that the automated lane 2 for entrance and the lane 3 for exit are
The vehicle detection devices 10, 12, 19 and the toll collection device 18 installed in the vehicle have basically the same configurations as the above-described vehicle detection device 5 and the toll collection device 7, and therefore the description is omitted.

Next, the translation pattern of the vehicle will be described. The vehicle translation patterns are:
A typical example is a pattern of a passenger car (including a mini car). Currently, a typical lane width of a tollgate is about 3 m, and it is considered that there is no actual translation pattern other than the above.

In the present invention, attention has been paid to the fact that the tread rarely changes greatly for each axis when one vehicle passes. Normal passenger cars and trucks do not change much if the treads for each axis are compared.
However, a vehicle with a side wheel or a vehicle towing a vehicle with a significantly different axle should be identified as a single vehicle, and the tread during passing may change significantly. The feature is detected so as not to be recognized, and is not erroneously detected as translation.

The principle of the tread detection method for the known tread 9 is that a switch embedded in the tread 9 in centimeters is turned on when a tire is pressed, and it is detected where the tire has passed on the tread 9. it can. Therefore, it is possible to know the width between the pressed tires by electrically recognizing the position intervals of the turned-on switches.

FIGS. 3 and 4 show typical tread changes during vehicle translation. In the case of normal single running, for example, the front wheel of the vehicle A is 1220 mm and the rear wheel is 1 mm.
It is a minicar having a 200 mm tread. Since the vehicle B is a motorcycle, the tread of both the front and rear wheels is 0.
mm. In normal single running, there is no vehicle whose tread changes significantly.

In the running shown in FIGS. 3 and 4, except for the pattern 5 in FIG. 4 (b), the tread for each axis greatly changes due to the translation of the vehicle. Pattern 1 in FIG.
For example, the first axis is 1820 mm, the second axis is 0 mm, and the third axis is 1200 mm. In other running patterns, the tread changes greatly by 1 m or more for each axis.

The pattern 5 in FIG. 4B has a feature that the tread does not change for each axis and is 0 mm, but the axis of the tread 0 having a different detection position on the tread 9 is detected.
It is considered that there is a strong possibility of the translation pattern of two motorcycles.

Incidentally, it is conceivable that two users of a single vehicle intentionally adjust the timing at which the tires pass on the tread plate 9 to disguise the running of an ordinary passenger car with a tread, but there is an advantage for the users. Therefore, it can be assumed that the probability of occurrence occurring by chance is low, and the improvement effect by detecting the translation by the above recognition is great.

Further, as a vehicle which is desired to be detected as one vehicle and whose tread may change, for example, there is a vehicle with a side wheel. Storage section 3 for standard tread values
2 in advance, and if data such as a vehicle length other than an ordinary vehicle is measured by the detection data from the vehicle length detection device 14, the vehicle will not be regarded as a translation as a car with a side car enters. I do.

Also, for example, a specific tow vehicle is similarly excluded from being recognized as a translation vehicle by registering its tread pattern and the like in the storage unit 32 in advance.

Next, the detection of the translation of the vehicle by the vehicle detection device 5 will be described with reference to the flowchart shown in FIG. This translation detection process is performed by the control unit 31. First, in step S1, when the shielding of the vehicle separator 8 is detected, that is, the leading end of the entering vehicle 4 is located between the light emitter 8a and the light receiver 8b, and the leading end of the vehicle 4 is detected. Then, the process proceeds to step S2.

In step S2, the vehicle 4 is controlled by the tread plate 9.
And the tread is measured (detected) at that time, and the process proceeds to step S3. In step S3, the tread measured in step S2 is temporarily stored in the storage unit 32. This processing is performed in step S4 by the vehicle separator 8
Until the rear end of the vehicle 4 is detected until the rear end of the vehicle 4 is detected, that is, the rear end of the traveling vehicle 4 is positioned between the light emitter 8a and the light receiver 8b.
The tread for each axis is measured and stored.

When the shielding of the vehicle separator 8 is released in step S4, the process proceeds to step S5. Step S5
Then, it is checked whether or not the measured tread for each axis differs by a predetermined value (for example, 1 m as an example, but another value can be considered by separate data collection).

If it is determined in step S5 that the treads of the respective axes do not differ from each other by a predetermined value or more, tread variation does not occur, but the translation of two motorcycles, which is pattern 5 in FIG. Step S6
Proceed to. In step S6, it is checked whether or not the translation pattern is that of two motorcycles (the tread for each axis is 0, and the axis is detected at a different position on the tread plate 9). Proceed to step S7. In step S7, assuming that no translation has occurred, the processing is performed as usual with one vehicle passing.

If it is determined in step S5 that the tread for each axis differs by a predetermined value or more, or if it is determined in step S6 that the two vehicles have a translation pattern, the translation is suspected. Proceed to. In step S8, it is finally checked whether or not the pattern is that of a side-mounted vehicle or a specific towing vehicle. This check is
For example, the detection is performed by comparing the detected tread pattern with the tread pattern of the specific vehicle stored in the storage unit 32 in advance.

If the check in step S8 indicates that the vehicle is not a translation vehicle, the flow advances to step S7, and the process is performed as usual by passing one vehicle. If the check in step S8 does not apply, the process proceeds to step S9,
Toll collection device 7 that there is a possibility or suspicion of translation
Notify to

In this way, the toll collection device 7 which has received the information on the translation of the vehicle, secures the operation of issuing the toll ticket,
It is also used as inspection information for fee collection. Note that the vehicle translation detection processing in the vehicle detection devices 10, 12, and 19 is also the same as that of the above-described vehicle detection device 5, and a description thereof will be omitted.

As described above, according to the above embodiment, when a vehicle passes the toll gate of the tollgate, the tread for each axis when one vehicle passes is measured, and the width of the amplitude is remarkable. By detecting the appearance, it is possible to detect the translation of the vehicle, and it is possible to take measures against inconvenience depending on the processing in each lane.

That is, in the automated lane at the entrance, since two vehicles that have been translated are conventionally recognized as one vehicle, the automatic ticket issuing device that receives the signal transmits the two vehicles. Only one ticket was issued, and it was only at the request of the user of the remaining vehicle that the event could be known. As a result, the response is delayed and the convenience of the user is greatly impaired.

Further, since the vehicle type is selected based on data measured when two vehicles pass at the same time, the data of the vehicle type and the number of axes recorded on one issued ticket May also include an error, and if a clerk does not notice at the exit tollgate, there is a possibility that a toll calculated from the wrong vehicle type may be collected.

It should be noted that the data of the number of axes is used as the data for the receipt inspection to estimate the approximate size of the processed vehicle, which is inconvenient for the inspection. However, according to the above-described embodiment, since the translation of the vehicle can be detected, the issuance of the toll ticket is temporarily stopped, and an alert is immediately sent to the entrance monitoring device to prompt the attendant to respond. With the entrance monitoring device,
Since the operation of issuing a passport is possible, the user is promptly started to issue the passport. Further, since the translation of the vehicle can be recorded as a record, it is possible to grasp the reason why the operation has to be performed manually, and it is possible to achieve a stricter audit.

In the manned lane at the entrance, the vehicle detection signal is transmitted to the toll collection device operated by the attendant only from the viewpoint of preventing the issuance of unnecessary toll tickets, which is illegal even in the manned lane. , And a toll ticket can be issued. Information on the vehicle type is recorded in a toll ticket or the like by operating a toll collection device at the discretion of a clerk when issuing a toll ticket.

Conventionally, since the two vehicles that have been translated are recognized as one, the toll collection device that has received the detection signal prompts the attendant to issue only one toll ticket.
The remaining vehicles will not be prompted to issue a toll ticket. For this reason, the clerk performs the operation of issuing a toll ticket to the toll collection device and issues the toll ticket even though there is no vehicle detection signal.

However, according to the above-described embodiment,
Since the translation of the vehicle can be detected, the reason that the above-mentioned work had to be performed can be recorded as a record of the translation of the vehicle, and the strictness of the receipt inspection can be improved.

Further, in the exit lane, since toll collection is performed, particularly strict inspection is required. One of them is the number of machines processed and the number of passing vehicles detected by the vehicle detection device. It is managed that the number is the same as the number. As described above, if the translation of the vehicle cannot be detected, the passage of the two vehicles is counted as one vehicle, and the logarithm processed is increased by one. In the above state, the number of machines processed is large,
You can audit that it is not a fraud factor, but if you understand that if the passing vehicle translates, the number of processed units will increase,
It is conceivable that the driver may observe the driving situation and remain as an uneasy factor such as not registering the processing for the next vehicle.

However, according to the above-described embodiment,
By transmitting vehicle translation information to the toll collection device,
The fact that the passing vehicle may have been translated is recorded in a form or the like, and the inspection can be stricter.

[0057]

As described in detail above, according to the present invention, it is possible to provide a vehicle detection device which can reliably detect the translation of a vehicle and can take measures against inconveniences depending on the processing in each lane. .
