Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a roadside wireless device used for vehicle operation management, etc.

Conventional configuration and its problems Recently, roadside wireless devices for monitoring the operation of buses and the like have come into wide use in cities.

By the way, all of these roadside wireless devices are provided independently from timetable display devices provided at bus stops and the like. Therefore, there are many opinions that these radio devices spoil the aesthetic appearance of cities, and there are various restrictions on where the radio devices can be installed. In addition, this type of wireless equipment is required to have relatively low output to avoid interference with other radio equipment, so even if bus lanes etc. are installed, recent road conditions etc. Taking this into consideration, the bus does not necessarily pass through the bus lane, and the distance between the bus and the radio becomes large, and the radio may not function correctly, which is not very desirable.

Purpose of the Invention The present invention is intended to eliminate the drawbacks of the above-mentioned conventional example, and aims to provide an excellent roadside wireless device with a simple configuration.

Structure of the Invention In order to achieve the above-mentioned object, the present invention has a structure in which a case housing a radio device is used as a bus timetable display board, and also serves as a bus timetable display device.

DESCRIPTION OF EMBODIMENTS The configuration of an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a roadside wireless device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line A-A' of the same embodiment, and FIG. 3 is a cross-sectional view taken along line B-B' of the same embodiment.

In Figures 1 to 3, 1 is a pole, and 2 is a case attached near the center of pole 1.The outer periphery of case 2 is made of metal or plastic, and the part facing the sidewalk is translucent. A bus timetable display board 3 is attached. Reference numeral 4 denotes an antenna mounted vertically on the pole 1, and this antenna 4 is connected to a radio set inside the case 2 via a cable 6.
Both 5a and 5b are metal fittings for attaching the antenna 4 to the pole 1. A U-shaped groove is formed in the center of one of the metal fittings 5a. 5c is metal fitting 5a,
These are bolts that tighten both ends of the metal fittings 5b to each other, and the antenna 4 is attached to the pole 1 by tightening the metal fittings 5a and 5b together with the antenna 4 inserted into the U-shaped groove formed in the metal fitting 5a.
It is intended for installation on the 7 is a display board attached to the tip of pole 1, and this display board 7
The bus stop name, bus company name, etc. are listed. Reference numeral 8 denotes a fluorescent lamp or other illumination device installed inside the case 1 to illuminate the timetable display board 3, and power is supplied to this illumination device 8 through a power line 10. 9 is a road radio device that wirelessly communicates with a radio device mounted on the bus via an antenna 4 connected with a cable 6 and monitors the passage of the bus;
This road radio 9 is connected to the case 2 by the bolt 12.
It is attached to the side opposite to the internal timetable display board 3. Power is supplied via the power line 11, and a portion is supplied to the lighting fixture 8 via the power line 10. The roadside radio 9 is installed opposite the timetable display board 3 so that a part of the bolt 12 is not noticeable to bus users waiting on the sidewalk and to efficiently illuminate the timetable display board 3. attached to the side. Furthermore, since the roadside radio 9 is waterproofed by the case 2, waterproofing can be omitted to that extent.

In this way, in the above embodiment, the roadside radio 9 is housed in the case 2 equipped with the bus timetable display board 3 and the roadside radio 9 is placed in the front to monitor the passing of the bus. It is possible to realize an excellent on-road radio device that can also serve as a time display.

Further, since the roadside radio device 9 is integrated with the bus stop, the bus radio device and the roadside radio device 9 can communicate over a short distance, so that these radio devices function accurately.

Furthermore, since the roadside radio 9 is installed on the road side inside the case 2, the roadside radio 9 can be installed without being noticeable to bus users, and the lighting device 8 can efficiently display the timetable display board 3. Can be lit.

Moreover, since power is supplied to the lighting device 8 and the roadside radio device 9 from the common power line 11 inside the case 2, the power supply wiring can be easily performed.

Furthermore, since the roadside radio device 9 is housed in the case 2, waterproofing of the roadside radio device 9 can be somewhat omitted.

Effects of the invention As is clear from the above embodiment, the present invention uses a case that houses a radio as a bus timetable display board and also serves as a bus timetable display device, so it has a simple structure. An excellent on-road wireless device can be realized.

In addition, since the radio was integrated with the bus stop,
Since the radio on the bus and the radio on the roadside radio device can communicate over a short distance, this has the effect that these radios function accurately.
