Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toll ticket issuing device that is installed at a toll road entrance or the like and automatically issues a toll ticket or the like on which the type of vehicle, etc., is written to the driver of an automobile.

Conventional technology Conventionally, this type of pass ticket issuing device was developed in U.S. Pat.
As stated in Publication No. 80871, there is a system in which a ticket is issued at one of multiple exits depending on the vehicle type. FIG. 1 is a device layout diagram of this conventional example, and FIG. 2 is a circuit diagram for wheel distance measurement of the conventional example.

In Fig. 1, 50 is a vehicle, 51 and 52 are vehicle separators that distinguish it from other vehicles, and 53 is a wheel width L whose resistance value changes due to tire pressure, as shown in Fig. 2. treadboard for detecting, 54, 55
5 is a vehicle height detector that detects whether it is a bus pattern or not.
6 is a ticket issuing machine, and 57 to 59 are ticket issuing ports. In Fig. 2, L is the wheel width, l is the tire width, a1 to c1, a2 to c2 are the measurement terminals, and r1 to
r6 is a resistance.

In FIGS. 1 and 2, when the vehicle 50 approaches the entrance, the treadle 53, vehicle separators 51, 52, and vehicle height detectors 54, 55 detect the wheel spacing,
The type of vehicle is determined by determining the number of axles and whether or not it is a bus, and a ticket issuing machine 56 issues a ticket. At this time, the pass ticket is issued from the issuance ports 57 to 59 at the upper, middle, or lower height depending on the vehicle type.

In this way, even in the conventional example, passes were issued from one of a plurality of issuing ports depending on the type of vehicle.

Problems to be Solved by the Invention However, in the above conventional ticket issuing device, as shown in Figure 2, two long resistance wires are buried in the road, a conducting wire is provided above the wires, and the weight of the tires causes the conducting wires to Since the distance between the wheels is determined based on the resistance value of the resistance wire, the distance between the wheels cannot be determined accurately, so a vehicle height detector is installed to determine whether the vehicle is a bus or not. Therefore, there was a problem in that the cost of the entire device was high.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide an excellent toll ticket issuing device that can accurately identify vehicle types and is inexpensive.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a large number of switches arranged in a staggered manner in the cross-road direction at intervals sufficiently narrower than the width of the tires, and detects the passing of a vehicle by pressing the tires. a passage detection device that detects the passing of a vehicle when the light is blocked by placing a light transmitting part and a light receiving part at both ends of the road; A treadle logic circuit that determines the number of axles and the number of wheels from the continuous state of closure of these switches during one detection of the treadle; The vehicle type is determined from the output signal of the tire spacing discrimination circuit and the above-mentioned tread logic circuit, and is recorded on a pass ticket, and this pass ticket is recorded when the tire spacing discrimination circuit distinguishes the vehicle as a small vehicle. The vehicle is configured to include a ticket issuing device that issues the ticket to the lower issuing port when the vehicle is a large vehicle, and issues the ticket to the upper issuing port when the vehicle is determined to be a large vehicle.

Effects According to the above configuration, the present invention determines the number of axles from the number of times the vehicle passes the treadle while the vehicle is being detected by the passing detection device, and determines the number of wheels from the continuous state of the switch being closed during one detection of the treadle. The vehicle type is determined by determining the distance between the wheels and the distance between the wheels, and a ticket is issued from the issuing port corresponding to the vehicle type, so the vehicle type can be accurately determined.Furthermore, the device does not require a conventional vehicle height detector, making it an inexpensive device. This means that the following can be configured.

Also, if the number of sensor blocks 16 to 24 is 5 or more, that is, A (8 cm) x 4 x 5 =
When the distance is 160 cm or more, it cannot pass through the AND gates 25 to 29 of the tire spacing discrimination circuit shown in FIG. 8, and a large vehicle signal is output from the output terminal 31.

Note that the inside of the sensor blocks 16 to 24 has a diameter of 4
Since the sensors are arranged in two rows in a staggered manner at 8 cm intervals, the tire width can be detected almost continuously without any breaks, and each sensor block 16 to 2
Even if the tires pass over the boundary of 4, there will be no error in measuring the tire distance. In the case of a small car
The _C8 code generation circuit 10 sends out the _C8 code "1", and the passage detection logic circuit 3 sends out _C1 to _C4 codes equivalent to vehicle type information, and sends them to the lane control device in the format shown in Figure 9. Sends vehicle height information and vehicle type information. The lane control device sends this information to the ticket issuing device 6.
, the ticket issuing device 6 prints the vehicle type information on the ticket, and based on the vehicle height information, the ticket is issued from the issuing port 5b for a small car and from the issuing port 5a for other vehicles.

In this way, according to this embodiment, vehicle height information is obtained using the tire spacing discrimination circuit that discriminates vehicles based on the spacing between the left and right tires, and the issuance port for issuing passes is changed based on the vehicle height. Tickets can be automatically issued at optimal locations for vehicles.

Note that in this example, eight sensors are
The system detects whether or not a tire passes each block, and determines the gap between the left and right tires when the tire passes, but if the spacing of each sensor that the tire passes is determined, the tire spacing can be determined accurately. can be measured.

Further, although a small car is determined by using every four sensor blocks such as B1 and B5, other numbers may be used depending on vehicle circumstances, sensor availability, etc.

Effects of the Invention As is clear from the above embodiment, the present invention determines the number of axles from the number of times the vehicle passes the treadle while the passing detection circuit detects the vehicle, and determines whether or not the switch is closed while the treadle is detected once. It accurately determines whether the vehicle is large or small based on the number of wheels and the distance between the wheels based on the continuous state, identifies the vehicle type, and issues a ticket from the issuing port corresponding to the vehicle type. This has the effect that the device can be constructed at a low cost since a vehicle height detector such as the one described above is not required.
