Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an automatic toll collection device provided on a toll motorway with a single section, multi-vehicle classification fee.

[Prior Art] Conventionally, in an automatic toll collection system used on a toll motorway in a single toll section, when a toll category is not classified and a rate that is not related to the type of car is set. , Automatic toll collection, automatic toll collection, a circuit breaker to cut off the passage of vehicles, and resetting of the circuit breaker according to the toll collection by the above automatic toll collection unit, and only one vehicle for which the fee has been paid is one by one. What consisted of the transmission detector made to pass was common.

Further, in the automatic toll collection system in which the fares are classified into two types of vehicles, namely "normal car" and "large car", the configuration is as shown in FIG. The figure is a real application 50-86
No. 811 (registration No. 1560523) shows the configuration of an automatic toll collection system, in which 1,1 'denotes a vehicle passage detection vehicle type discriminating unit for detecting the passage of a vehicle 8 and discriminating the type of vehicle, 2, 2 'is a passing vehicle height detector, 3 is an automatic toll collection device, 4 and 4' are presence detectors, 5 is a circuit breaker, 6 and 6 'are transmission detectors, and 7 is a circuit breaker protection device. Each of the above devices is provided at the entrance gates 9 and 9 'of the toll road along the passing direction of the vehicle 8, and the vehicle type is generally set to "normal vehicle" and "normal vehicle" This was detected only when a vehicle other than the one passed by, and changed to the set fee corresponding to the "large vehicle".

[Problems to be Solved by the Invention] Among toll roads, particularly, urban expressways such as the Metropolitan Expressway and the Hanshin Expressway have mostly single toll sections, and the vehicle types are classified as "ordinary vehicles" and " Many vehicles are classified into only two types, "large vehicles". By the way, in recent years, the classification of vehicles on toll roads has tended to be subdivided from two conventional vehicle classifications into multiple vehicle classifications, that is, about 4 to 5 vehicle classifications, which cannot be handled by the conventional automatic toll collection system. There is a demand for an automatic toll collection device on a toll road corresponding to a vehicle type classification. The automatic toll collection system that supports this new multi-vehicle classification cannot use a submerged underground vehicle weight detection device, commonly known as a tread plate, because many urban expressways have elevated structures. In addition, the vehicle type determination must be performed irrespective of the vehicle weight, which serves as one indicator for determining the vehicle type.

The present invention has been made in view of the above circumstances,
An object of the present invention is to provide an automatic toll collection device applicable to an urban expressway corresponding to a multi-vehicle classification without detecting a vehicle weight.

[Means and Actions for Solving the Problems] That is, the present invention provides a first vehicle separation that is disposed on the entrance side of a toll motorway with a single-section, multi-vehicle classification toll and separates and detects passing vehicles one by one. , A vehicle type discriminator that reads the license plate of the vehicle separated and detected by the first vehicle separator and performs vehicle type discrimination according to the multi-class classified fee, and an automatic device that automatically collects a fee according to the vehicle type discrimination result. A toll collection device and a vehicle disposed downstream of the passing vehicle from the automatic toll collection device to separately detect passing vehicles one by one and to allow only vehicles for which a prescribed fee has been received by the automatic toll collection means to pass through. A second vehicle separator with a circuit breaker is provided, so that the type of vehicle can be determined based on the presence / absence of a license plate attached to the front side of the vehicle and its size and content, and the detection of vehicle weight can be performed. It does not require a submerged underground type vehicle weight detection device or the like, and can be sufficiently applied to multi-vehicle classification on an urban expressway.

The detection signals from the light receivers R31 to R3n become the passing signal f via the OR circuit 201 as they are, and are input to the set terminal S of the flip-flop 203 for forward / reverse determination and the AND circuit 204. The detection signal at the light receiver R31 located at the uppermost part of the light receivers R31 to R3n is also a vehicle height signal e,
The detection signal from the photodetector R3n located at the lowermost position is sent to the pattern detection circuit 223 as an axle signal d.

In addition, the second vehicle separators 13 and 14 are also the first vehicle separators 11 and

It is composed of 1 to P4n and photodetectors R41 to R4n opposed thereto, and is signal-controlled so that mutual interference does not occur. The detection signals from the light receivers R41 to R4n are input as they are to the D terminal of the flip-flop 224 and the AND circuit 204 via the OR circuit 202 as the passing signal h. The detection signal at the light receiver R41 located at the uppermost position of the light receivers R41 to R4n is also a vehicle height signal g, and the detection signal at the light receiver R4n located at the lowermost position is as an axle signal c to the pattern detection circuit 223. Sent out.

The pattern detection circuit 223 recognizes the pattern shape of the vehicle 10 based on the vehicle height signals e and g, the axle signal c, the vehicle length signal b, and the overhang signal a, which are the input signals, and converts the vehicle pattern signal j into a vehicle type discriminator. The data is sent to the vehicle type determination unit 211 in 222.

The flip-flop 224 is connected to the Q of the flip-flop 203 in synchronization with the fall of the axle signal d from the OR circuit 202.
The forward signal o output from the terminal is input to the AND circuit 205. The AND circuit 205 also includes the AND circuit 2 described above.
The output of 04 is input, and the output is sent to the camera 206 composed of the vehicle photographing camera 15 as an imaging signal x.

The camera 206 has an electronic image pickup device such as a CCD device inside, and performs an image pickup operation of a license plate portion of the vehicle 10 in synchronization with the input of the signal x, and an image signal obtained by image pickup is an image signal. The image data is sent to the A / D converter 207 in the processing unit 221 and converted into digital data here.
Written to 208. When one image is written in the image memory 208, the image data is read by the image reading unit 209 and sent to the character recognition unit 210. Character recognition unit 210
Recognizes the size of the license plate and the small number part indicating the vehicle type based on the transmitted image data and converts it into a character signal, and transmits the character signal l to the vehicle type determination unit 211 in the vehicle type determination device 222.

The vehicle type discriminating unit 211 includes a vehicle pattern signal j and a character signal l.
And the vehicle type signal m based on the vehicle type fee
The charge is sent to the charge matching circuit 212 and the set charge display section 225 in the automatic charge collection device 16.

The automatic toll collection device 16 includes the above-described set fee display unit 225, a coin discriminating unit 213, and a fee calculation unit 214. The set fee according to the vehicle type signal m is output and displayed on the set fee display unit 225, and is inserted. The coin type and the number of coins are determined by a coin discriminating unit 21.
It discriminates in 3 and outputs the discrimination result to the charge calculation unit 214.

The vehicle type / charge matching circuit 212 in the vehicle type determination device 222 determines whether the vehicle type signal m from the vehicle type determination unit 211 matches the toll signal n, and sets a break signal 17, 18 to open when the two match. s is sent to the above-described circuit breakers 17 and 18.

By the way, the third vehicle separators 19 and 20 are composed of a plurality of light transmitters P41 arranged in a line in the vertical direction like the first vehicle separators 11 and 12 and the second vehicle separators 13 and 14. PP4n and photodetectors R5151R5n opposed thereto, and are signal-controlled so that mutual interference does not occur. The detection signals from the light receivers 51 to R5n become the passing signal r via the OR circuit 215 as they are, and are input to the set terminal S of the flip-flop 218 for forward / backward discrimination, and the AND circuit 219 via the OR circuit 217. Is input to

Similarly, the fourth vehicle separators 21 and 22 also include a plurality of light transmitters P61 to P6n arranged in a line in the vertical direction and light receivers R61 to R6n opposed thereto, and no mutual interference occurs. Signal is controlled as follows. The detection signals from the photodetectors R61 to R6n are directly input to the AND circuit 219 via the OR circuit 217 as the passing signal q via the OR circuit 216.

The forward signal p output from the Q terminal of the flip-flop 218 is input to the AND circuit 219. Then, the output of the AND circuit 219 is input to the D terminal of the flip-flop 220. The flip-flop 220 sends a reset signal t to the reset terminal R of the flip-flop 218 in synchronization with the fall of the input from the D terminal, and sends the reset signal t to the circuit breakers 17 and 18 to send the reset signal t to the vehicle. The shut-off operation is executed so that 10 does not pass.

In the above configuration, the operation is as follows.

First, when the vehicle 10 approaches the installation position of the first vehicle separators 11 and 12, the light transmitters P31 to P3 of the first vehicle separators 11 and 12 are transmitted.
The transmission and reception of the optical signal between n and the light receivers R31 to R3n are partially interrupted and detected by any of the light receivers R31 to R3n, and the detection signal is passed through the OR circuit 201 as a passing signal f as a flip-flop. The signal is input to the set terminal S of the 203 and the AND circuit 204. The forward signal o of the flip-flop 203 is sent to the AND circuit 205 by the passing signal f.

After that, the vehicle 10 moves forward and the second vehicle separator
When reaching the installation positions of the light receiving devices 13 and 14, the transmission and reception of optical signals between the light transmitters P41 to P4n and the light receivers R41 to R4n of the second vehicle separators 13 and 14 are also partially blocked, It is detected by any of the devices R41 to R4n, and the detection signal is passed through the OR circuit 201 as the passing signal h to the flip-flop 224 and the AND circuit 204.
Entered as Here, since the AND circuit 204 has already been opened by the passing signal f, the output of the AND circuit 204 changes from “0” level to “1” by the passing signal h.
The level is input to the AND circuit 205. By the output of the AND circuit 204, the output of the AND circuit 205 which has already been opened by the forward signal o also changes from the "0" level to the "1".
Level, and this is sent to the camera 206 as the imaging signal x.

The camera 206 captures a front image including a portion corresponding to the license plate of the vehicle 10 approaching the installation position of the second vehicle separators 13 and 14 which has been previously focused according to the imaging signal x. The analog-valued image signal obtained by the camera 206 is first digitized sequentially by the A / D converter 207 in the image processing unit 221 and written into the image memory 208. The digital value image data written in the image memory 208 is read out by the image reading unit 209 when one image data is written, and sent to the character recognition unit 210. The character recognizing unit 210 performs character recognition on the small number part indicating the vehicle type of the license plate in the image data by pattern recognition, and sends the recognition result as a character signal l to the vehicle type determining unit 211 of the vehicle type determining unit 222.

Thereafter, when the vehicle 10 further advances from the installation position of the second vehicle separators 13 and 14 and approaches the installation positions of the overhang detectors 113 and 114 and the vehicle length detectors 115 and 116, the first vehicle separators 11 and The detection of the vehicle height, the vehicle length and the overhang is performed by combining the detection signals from the second and second vehicle separators 13 and 14, and the pattern detection of the vehicle 10 is performed by integrating these detection results.

That is, the front wheels of the vehicle 10 are the first vehicle separators 11, 12,
The detection signals from the respective lowermost light receivers R3n, R4n are sent to the pattern detection circuit 223 as the axle signal d and the axle signal c when the second vehicle separators 13, 14 are approached. At this time, the pattern detection circuit 223 determines whether or not the vehicle 10 is a bus based on the presence or absence of the overhang signal a from the light receiver R1 of the overhang detector 113. Also,
When the vehicle 10 has completely passed through the installation positions of the second vehicle separators 13 and 14, the passing signal h output from the OR circuit 202 falls, so that the flip-flop 224 latches this and the flip-flop 203 The reset signal k is sent to the pattern detection circuit 223. When the reset signal k is input, the pattern detection circuit 223 detects the light receiving device R2 of the vehicle length detector 115.
It is determined whether or not the vehicle 10 is something other than a minicar based on the presence or absence of the vehicle length signal b. The pattern detection circuit 223 creates a vehicle pattern signal j based on these determination results, and sends it to the vehicle type determination unit 211 in the vehicle type determination device 222.

The vehicle type discriminating unit 211 corresponds to the vehicle pattern signal j and the character signal l, and generates a vehicle
While discriminating the ten vehicle types and outputting the vehicle type signal m as a result of the determination to the vehicle type / rate matching circuit 212, the set price display unit 2
The vehicle type signal m is also output to 25, and the set price corresponding to the vehicle type is displayed and output on the set price display section 225.

The vehicle 10 moves forward to the installation position of the automatic toll collection device 16, and aims at the set fee displayed on the set fee display unit 225, and cures the amount corresponding to the fee from the curing input hopper (not shown). I do. The type of the hardening that has been input is sequentially determined by the coin determination unit 213, and the determination result is sent to the charge calculation unit 214.The charge calculation unit 214 adds and calculates the total amount according to the determination result. The calculation result is sequentially transmitted to the vehicle type / rate matching circuit 212 as a rate signal n. The vehicle type / rate matching circuit 212 compares and compares the price signal n from the price calculation unit 214 with the vehicle type signal m from the vehicle type determination unit 211, and determines the content of the vehicle 10 as the content of the price signal n.
The set signal s, which is the coincidence signal, is turned off when the total input amount of the
Send to 17,18. The breaker 17,
18 are opened upward, respectively, so that the vehicle 10 can pass through the circuit breakers 17,18.

The vehicle 10 passes through the circuit breakers 17 and 18, and the third vehicle separator 1
When reaching between 9 and 20, the transmission and reception of optical signals between the light transmitters P51 to P5n and the light receivers R51 to R5n of the third vehicle separators 19 and 20 are partially blocked, and the light receivers R51 to R5n And the detection signal is input to the set terminal S of the flip-flop 218 via the OR circuit 215 as the passing signal r and to the AND circuit 210 via the OR circuit 217. The forward signal p from the Q terminal of the flip-flop 218 is generated by the passing signal r.
Is sent to the AND circuit 219. Since the two inputs of the AND circuit 219 are both at the "1" level at this time, the output thereof also becomes the "1" level, which is sent to the D terminal of the flip-flop 220.

After that, the vehicle 10 moves forward and the fourth vehicle separator
When reaching the installation position of 21,22, the transmission and reception of optical signals between the light transmitters P61-P6n and the light receivers R61-R6n of the fourth vehicle separators 21,22 are also partially blocked, The signal is detected by any of the devices R61 to R6n, and the detection signal is input to the AND circuit 219 via the OR circuit 217 as the passing signal q via the OR circuit 216.

When the vehicle 10 further moves forward and passes through the installation positions of the third vehicle separators 19 and 20, the passing signal r output from the OR circuit 215 falls, but at the same time, the passing signal q from the OR circuit 216 falls. Is input to the AND circuit 219 via the OR circuit 217, so that there is no effect.

When the vehicle 10 finishes passing the installation positions of the fourth vehicle separators 21 and 22, the passing signal q output from the OR circuit 216 also falls, so that the input to the AND circuit 219 changes from the “1” level. Since it drops to “0” level, the AND circuit 21
The output of 9 also falls to the “0” level. This is latched by flip-flop 220, flip-flop 218, breaker
Send to 17,18. The breaker 1
7, 18 are each lowered again, so as to block the passage of the next vehicle.

Next, a description will be given of the logic of the vehicle type determination performed mainly in the vehicle type determination unit 211 of the vehicle type determination device 222.

First, as shown in FIG. 3, the vehicle types are classified into five types such as mini vehicles, one type of ordinary vehicles, four types of medium-sized vehicles, two types of large-sized vehicles, two types of oversized vehicles, and the like. Classification is based on a total of six large bus types. Here, the type of car, license plate information, number of axles,
And so on.

FIG. 4 shows the content of the logic of the vehicle type determination. When performing the determination, first, as shown in step S1, it is determined whether or not the vehicle length of the vehicle 10 is less than 3.3 [m]. This is the second installed at 3.3 [m] intervals.
The pattern detection circuit 223 detects the light receiver R2 of the vehicle length detector 115 when the reset signal k is input from the flip-flop 224 when the reset signal k is input from the flip-flop 224. Is determined by determining whether or not the vehicle length signal b has been input from. If it is determined that the vehicle length is less than 3.3 [m], the vehicle 10 is immediately determined to be a mini vehicle of the vehicle type 5, and a vehicle pattern signal j indicating this is sent from the pattern detection circuit 223. It is sent to the vehicle type discriminator 211 of the wheel type discriminator 222.

If it is determined in step S1 that the vehicle length is equal to or greater than 3.3 [m], the process proceeds to step S2 to determine whether the overhang from the front wheels of the vehicle 10 to the front side is equal to or greater than a certain value. I do. This is because the pattern detection circuit 223 detects that the front wheels of the vehicle 10 pass through the installation positions of the second vehicle separators 13 and 14 and are located at the lowermost positions of the light receivers R41 to R4n of the second vehicle separators 13 and 14. It is determined whether or not the overhang signal a, which is the detection signal of the light receiver R1 on the side of the overhang detector 114, is input when the axle signal c, which is the detection signal of the light receiver R4n, is transmitted. It is done by doing. If the overhang signal a is input, and thus the overhang from the front wheels to the front portion is longer than a certain value, the vehicle 10 is immediately determined to be the large bus of the vehicle type 6, and this fact is indicated. The indicated vehicle pattern signal j is transmitted from the pattern detection circuit 223 to the vehicle type determination unit 211 of the wheel type determination device 222.

FIG. 5 is a timing chart showing signal waveforms when the vehicle 10 is a large bus, and is shown in FIG. 5 (7) before the pulse of the axle signal c shown in FIG. 5 (6) is detected. Since the pulse of the overhang signal a is detected, it is understood that the vehicle 10 is a large bus with a special overhang as compared with other types of vehicles.

If it is determined in step S2 that the overhang from the front wheel to the front portion is not longer than a certain value, then it is determined in step S3 whether a license plate is present. This is because the character recognition unit 210 of the image processing unit 221 determines by pattern recognition from the image data read by the image reading unit 209, and recognizes the pattern of the license plate in the image data. Then, the process proceeds to step S4 to determine whether the size of the license plate is "large" or "medium". This is determined from the size of the license plate in the image data.If it is "medium", the process proceeds to step S5, and what is the number of the model number indicated by the small number portion in the license plate Recognize and judge. This number is represented by one or two digits. If the number is one digit, the number is determined. If the number is two digits, the number on the left side is determined. The determination result is a vehicle type determination unit 211 of the vehicle type determination device 222. Is sent as a character signal l.

If the number of the model number is any one of "3", "4", "5", "6", and "7", the vehicle 10 having the license plate is a normal vehicle of the vehicle type 1 or a medium-sized vehicle of the vehicle type 4. Therefore, the process proceeds to step S6, and it is determined whether the number of axles is two or three. The number of the axles is equal to the light receivers R41 to R4 of the second
The axle signal c, which is a detection signal at the light receiver R4n located at the bottom of n, or the light receivers R31 to R31 of the first vehicle separators 11, 12
This is obtained by counting the number of axle signals d, which are detection signals by the light receiver R3n located at the bottom of R3n, by the pattern detection circuit 223, and the count value is superimposed on the vehicle pattern signal j to perform pattern detection. The signal is transmitted from the circuit 223 to the vehicle type determination unit 211. If the vehicle type number is one of “3” to “7” and the number of axles is two, the vehicle type determination unit 211 determines that the vehicle 10 is a normal vehicle of the vehicle type 1. . Also, the number of the model number is "3" ~
If it is determined to be one of "7" and the number of axles is 3, it is determined that the vehicle 10 is a medium-sized vehicle of vehicle type 4.

In step S5, the model number is “1”.
If it is any of "2", the vehicle 10 having the license plate is a medium-sized vehicle of the vehicle type 4 or a large-sized vehicle of the vehicle type 2, so that the process proceeds to the step S7 and proceeds to the step S6. Similarly, it is determined whether the number of axles is two or three. The model number is "1"
If it is determined that the vehicle 10 is any of "2" and the number of axles is 2, it is determined that the vehicle 10 is a medium-sized vehicle of vehicle type 4. When it is determined that the number of the vehicle type number is either “1” or “2” and the number of axles is 3, it is determined that the vehicle 10 is a large vehicle of the vehicle type 2.

If it is determined in step S5 that the number of the vehicle type number is "9", it is determined that the vehicle 10 having the license plate is an oversized vehicle of vehicle type 3.

Furthermore, if it is determined in step S5 that the number of the vehicle type number is “8” or that the vehicle type cannot be recognized and is unknown, the vehicle type cannot be specified.

If it is determined in step S4 that the size of the license plate is "large", then the process proceeds to step S8, and the vehicle type number indicated by the small number portion in the license plate as in step S5. Recognize and judge what is.

If the number of the vehicle type number is "1", the vehicle 10 having the license plate is a large vehicle of the vehicle type 2 or an oversized vehicle of the vehicle type 3, so that the next step S9
To determine whether the number of axles is 4 or less or 5 or more. If it is determined that the number of axles is four or less, it is determined that the vehicle 10 is a large vehicle of the vehicle type 2. Also,
When it is determined that the number of axles is 5 or more, it is determined that the vehicle 10 is an oversized vehicle of the vehicle type 3.

If it is determined in step S8 that the number of the vehicle type number is "2" or "8", then in step S10
To determine whether the number of axles is four or less, or five or more, as in step S9. If it is determined that the number of axles is four or less, the vehicle type cannot be specified. When it is determined that the number of axles is five or more, it is determined that the vehicle 10 is a specific vehicle of the vehicle type 3.

Further, if the license plate is not recognized in step S3 and the pattern is that of a commercial vehicle, a Self-Defense Force, a foreign official vehicle, or a forwarding vehicle, or it is determined in step S4 that the size of the license plate is unknown. If
The process directly proceeds to step S10.

If it is determined in step S5 that the number of the vehicle type number is "9", and if it is determined in step S10 that the number of axles is four or less, the vehicle type cannot be specified in any case. It is also conceivable to call a clerk using a call button (not shown) provided on the automatic collection device 16 and pay the set fee.
