PURPOSE:To realize effective bus radio system and to enable to achieve efficient bus operation service, by incorporating the bus stops with antenna and radio transceivers. CONSTITUTION:The system is constituted with the instruction stations 20, 21 and relay station 50 (bus stop). At the relay station 1 using microwave, parabola antennas 1, 7 having sharp directivity and high gain, microwave transceivers 2, 4, relay distributor 3, terminal unit 5, and power supply 6, and the station relays 3 the upper and down signals and connects a part of signals to the terminal unit 5. Further, the terminal unit 5 displays the signal from the stations 20 and 21 to the guide display plate to passengers, and if required, the conditions of bus waiting is connected to the transceivers 2 and 4 with key operation of the passengers waiting a bus as an electric signal to inform it to the stations 20 and 21. |
