Wireless communication is performed between the on-board wireless device 37 attached to 6 and the road antenna 33 to confirm the function of the on-board wireless device 37, and the result is displayed on the screen of the personal computer 35. The gantry 32, the road antenna 33, the high-frequency unit 34, and the like are the same as those used in the actual toll collection system.

[0005]

SUMMARY OF THE INVENTION
After being attached to the vehicle 36, it cannot be easily removed, and it is necessary to perform an inspection while the vehicle is attached to the vehicle. Currently used methods are the same gantry 32 and street antenna 33 as used for actual toll collection.
In addition, it is necessary to use the high-frequency unit 34 and the apparatus becomes large-scale. In addition, the above-mentioned road antenna 33
In this case, it is necessary to set a large number of antenna patches in order to increase the directivity of a transmission radio wave, and the external size becomes large. Also, the function of the in-vehicle wireless device is checked and the result of the check is displayed by using the personal computer 35.
No. 5 has a problem that it cannot be installed outdoors, and the place where wireless communication is performed and the place where results are displayed are separated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to easily perform an inspection of a vehicle-mounted radio device mounted on a vehicle, thereby greatly reducing the inspection time per vehicle. It is another object of the present invention to provide an on-vehicle wireless device inspection apparatus that can be obtained and can be reduced in size and cost.

[0007]

According to the present invention, there is provided an on-vehicle wireless device inspection apparatus provided with a portable small antenna device for performing wireless communication with an on-vehicle wireless device mounted on a vehicle, and the antenna device. A display for displaying the test results;
A modulation / demodulation circuit connected to the antenna device via a cable for modulating test data for the in-vehicle wireless device and demodulating response data from the in-vehicle wireless device, and a function of the in-vehicle wireless device based on response data from the in-vehicle wireless device And a control unit including a processing device for displaying a result of the determination on a display of the antenna device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view showing a configuration of an on-vehicle wireless device inspection apparatus according to one embodiment of the present invention. As shown in FIG. 1, the on-vehicle wireless device inspection device according to the present invention includes a portable small antenna device 11 and a control unit 12, and the antenna device 11 and the control unit 12 are connected by a cable 13. I have. The control unit 12
Although not shown, a CPU (processing device) having a determination function and a modulation / demodulation circuit are integrated with each other, and are installed at a place where a vehicle-mounted wireless device is inspected.

The antenna device 11 and the vehicle 14
The function of the in-vehicle wireless device 15 is confirmed by performing wireless communication with the in-vehicle wireless device 15 attached to the device. As shown in FIGS. 2A to 2C, the antenna device 11 is provided with a round bar-shaped holding portion 21 below a base 20 having a rectangular shape, for example.

Goes to the vicinity of the vehicle 14 with the antenna device 11 in hand, and operates the transmission switch 22 with the front surface of the antenna device 11 facing the on-vehicle wireless device 15. By operating the transmission switch 22, the test data modulated by the modulation circuit of the control unit 12 is transmitted from the transmission antenna patch 25 to the on-vehicle wireless device 15.

When receiving the test data transmitted from the transmitting antenna patch 25 of the antenna device 11, the on-vehicle wireless device 15 transmits response data to the test data. This response data is received by the receiving antenna patch 24 of the antenna device 11 and sent to the control unit 12 via the cable 13. The control unit 12 includes a vehicle-mounted radio 15
Demodulates and checks the response data from the
It is determined whether or not the function of No. 5 is normal, and the result of the determination is transmitted to the antenna device 11 via the cable 13. The determination result sent from the control unit 12 to the antenna device 11 is displayed on the display 23.

Therefore, the inspector 16 operates the transmission switch 2 provided on the antenna device 11 near the vehicle 14.
By simply operating the device 2, the function of the on-vehicle wireless device 15 can be easily confirmed by the data displayed on the display 23.
