And a battery 2 3. The identification information 24 of vehicle 2 (m) is stored in ROM. Transmitter / receiver module 2 1

_{! 5 The} traffic management information S1 transmitted from the communication device 30 (n) is received. The received information is stored and held in RAM. The transmission / reception module 21 receives a response request signal R from the gate-side communication device 30 (n). , 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 transmits the response request signal R, the gate information 5 11 1 and the traffic management information S to the vehicle-side communication device 20 of the vehicle 2 passing through the gate 10. , A transmission / reception module 31 for receiving 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, and information received by the transmission / reception module 31 Function to calculate the toll of vehicle 2 that has passed through gate 10 based on the above, RAM that stores the calculated toll and reception information in a _0- associated manner, and RAM that stores gate information 11 And a power supply 33.

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, Reality - play Bok _c is also desirable to place the vehicle-side communication device 2 0 in a portion of the vehicle-side communication device 2 0 during vehicle operation always, outgoing ready vehicle identification information ( That is, it must be set to (operating state).

5 For this purpose, as shown in FIG. 2, an in-vehicle battery is used as a power source for the communication device 20 and the key-in is performed. 0 power supply 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 to the inoperable state 5 without permission, the driver visually checks whether the communication device 20 is operating from the outside. It is desirable to install an indicator lamp that can be identified by

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

α _ο In the example shown in this figure, the license plate 70 is a box-shaped storage case 71, a number plate body 73 attached to the side opening 72 of this storage case 71, and mounted in the space between them. And a transmission / reception circuit board 74 and an antenna plate 75. Co _{1 5} when the surface of the transmitting and receiving circuits board 7 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 attached . The luminous body 7 is arranged at the same position as the seal 78 attached to the license plate main body 73, and is in a state of being covered by the seal 78. This seal 7 8 is made of a transparent material, and therefore, from outside via the seal 7 8

_You can check whether the 20 light emitter 77 is on or off.

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 may itself be directional and may be ₂₅ . When giving directivity to the built-in antenna, for example, as shown in Fig. 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 ST2), and if there is communication, communication is attempted in five different free frequencies. If there is no communication in the same frequency band, a response request signal R is transmitted (step ST3).

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), carries out carrier sensing (step ST12), and executes the idle frequency band. wave

When the vehicle passing through the gate receives this confirmation signal (step ST6), it returns to the reception standby state (step ST7). Similarly, the gate side returns to the standby state

₂₀ (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. Communication is performed by automatically switching to a free 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 drive power supply so as to be turned on / off in conjunction with on / off of the 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 30A and a check gate 30B. 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 30 are appropriate. This is to prohibit the vehicle from entering the toll road 1 if it has not been done.

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 (n) of this example has an exit road 30C for returning vehicles that cannot enter the expressway from the check gate 30B 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 30E equipped with a ticket issuing machine that issues tickets for entering the expressway is equipped, even if the vehicle has a broken 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.
