Gate information 1 1 (n) can be received. On the other hand, each gate-side communication device 30 (n) can receive the identification information 21 (m) of the passing vehicle 2 (m), and the gate information 1 1 (n ) Can be sent.

Figures 2 (A) and (B) show the vehicle-side communication device and the gate-side communication device. FIG. 3 is a schematic block diagram of the device. Referring to these figures, the communication device 20 (m) on both sides of the vehicle includes a transmission / reception module 21, a microcomputer unit 22 having ROM and RAM, and a power supply as a power supply. And on-vehicle battery 23. The identification information 24 of the vehicle 2 (m) is stored in the ROM. The transmission / reception module 21 receives the traffic management information S1 transmitted from the gate-side communication device 30 (n). The received information is stored and held in the RAM. The transmission / reception module 21 receives a response request signal R from the gate-side communication device 30 (n). Is received, the identification information 24 and the information held in the RAM are transmitted to the gate-side communication device 30.

 On the other hand, the gate-side communication device 30 sends the response request signal R and the gate information to the vehicle-side communication device 20 of the vehicle 2 passing through the gate 10.

The transmission / reception module 31 transmits the vehicle identification information 24 and the traffic management information S 2 transmitted by the vehicle-side communication device 20 in response to the response request signal R while transmitting the traffic management information S 5. A toll calculation function for calculating the toll of vehicle 2 that has passed through gate 10 based on the information received by the transmission / reception module 31;

The request signal R is transmitted to ensure communication with the passing vehicle 2.

 Next, a preferred configuration of the vehicle-side communication device 20 will be described. As described above, the vehicle-side communication device 20 transmits the vehicle information for identifying the vehicle. Since it is intended to transmit a signal, it is desirable that the driver cannot remove it without permission. For this purpose, it is desirable to dispose the vehicle-side communication device 20 in the portion of the pick-up plate. <Also, the vehicle-side communication device 20 is in a state where vehicle identification information can always be transmitted while the vehicle is driving. (Ie, operating state).

S For this purpose, as shown in FIG. 2, a vehicle-mounted battery is used as a power source for the communication device 20 and the vehicle is connected and turned to the ON position of the vehicle electrical component, and the communication device 20 is turned on. Power supply for device 20 It is desirable that a path is also formed. In this way, in the vehicle driving state, the communication device 20 is always supplied with power and can transmit the vehicle identification information.

 In addition to this configuration, in order to prevent the driver from setting the communication device 20 in an inoperable state without permission, it is visually determined from outside whether or not the communication device 20 is operating. It is desirable to install an identifiable indicator lamp.

 FIG. 3 shows an example of mounting the vehicle-side communication device 20 on the license plate of the vehicle.

In the example of this figure, the pick-up plate 70 is mounted in a box-shaped storage case 71, a number plate main body 73 mounted on the side opening Ί2 of the storage case 71, and a space therebetween. And a transmission / reception circuit board 74 and an antenna plate 75. Co 5 when the surface of the transmitting and receiving circuits board I 4 transceiver module I 6 are mounted, emitting light body 7 7 such as an LED that lights up if the receiving circuit is in operation is mounted. The luminous body 77 is arranged at the same position as the seal 78 attached to the license plate main body 73, and is covered by the seal 78. This seal 78 is made of a transparent material, and therefore from the outside via the seal 78. Lighting / extinguishing of illuminant 77 can be confirmed.

 Here, the entire storage case 71 may be formed of a non-conductive material, or only a part of the storage case 71 may be made of a non-conductive material in order to provide directivity to the built-in antenna plate 75. It may be formed from a conductive material. Of course, the built-in antenna plate 75 itself may be made directional. If you want the built-in antenna to have directivity,

As shown in 4, it is desirable to have directivity in the vertical direction. Next, FIG. 5 is a flowchart showing the operation of the vehicle operation management system 3 of this example. It is one chart. First, the gate is ready to wait for a vehicle and continues to make outgoing calls (step ST1). In this transmission operation, carrier sensing is performed to detect the presence or absence of communication in the same frequency band (step ST 2).

5 Attempt to communicate on the frequency. If there is no communication in the same frequency band, a response request signal R is transmitted (step ST 3).

 On the side of the vehicle passing through the gate, the vehicle approaches the gate in a receivable standby state, receives a response request signal R (step ST11), performs carrier sense (step ST12), and becomes idle. Frequency band wave

The length is transmitted to the gate side such as vehicle identification information 24, traffic management information S2, etc. (step ST13).

 When the gate receives a control signal including the identification information 24 and the traffic management information S2 from the vehicle (step ST4), the gate transmits the gate information 11 of the gate to the vehicle (step ST5). ). Gate

On receiving the gate information 11 from the gate side (step ST14), the 15 side transmits a confirmation signal to the gate side to confirm the reception (step ST15). When the vehicle passing through the gate receives this confirmation signal (step ST6), the vehicle returns to the reception standby state (step ST7). Similarly, the gate side returns to the standby state

2 . (Step ST16).

 Thus, in the vehicle-side communication device 20, the carrier sense is communicated with the gate side before communication so that it is not difficult to recognize the same frequency when a plurality of vehicles enter the gate in a row. The communication is performed by automatically switching to the idle channel frequency. Follow

In addition, even when many vehicles are connected, communication with each vehicle can be performed reliably.

Next, in the vehicle operation management system 3 of the present example, the vehicle driver It is desirable to arrange a notifying means for notifying that the mounted communication device is in an operating state in an operating section of a driver's seat so that it can be checked. Such an informing means may be a display lamp attached to the operation surface of the driver's seat of the vehicle, or a sound display means such as a speaker attached to the driver's seat. Of course, both of them may be equipped. Such an informing means may use an in-vehicle battery as a driving power so that the on-off is turned on and off in conjunction with the on-off of an on-vehicle accessory power supply.

Here, in the vehicle traffic management system 3 of the present example, each gate 10 (n) is a double gate system. That is, as shown in FIG. 6, each gate 10 (n) includes a communication gate 30 A and a check gate 30 B. The communication gate 30A includes the gate-side communication device 30 (n) having the above configuration, and transmits and receives gate information and vehicle identification information to and from a passing vehicle. The check gate 30B is located closer to the vehicle than the communication gate 30A , and the transmission and reception of the gate information and the vehicle identification information in the communication gate are appropriate. This is to prohibit the vehicle from entering the toll road 1 if it has not been performed.

 Thus, in this example, each gate is a double gate system. According to this configuration, it is determined that the communication device of the vehicle is not operating.

2 . Can be notified.

 In addition, the gate 10 (η) of this example has an exit road 30C for returning a vehicle that cannot enter the expressway from the check gate 30 3 to the general road. In this case, a fork 30 D that returns to the toll road is formed in the middle of the exit road 30 C.

2 5 If a gate 30 0 equipped with a ticket issuing machine that issues tickets for entering the expressway is equipped, even if the vehicle has a malfunctioning communication device, Can be used. The above description is an example in which the present invention is applied to a highway operation management system. The present invention can be similarly applied as a vehicle operation management system in a parking lot. In addition, the present invention can be similarly applied to an operation management system for vehicles entering and exiting a specific section such as a factory facility.
