Problems solved by technology

Also, it is unrealistic for the driver to operate the antenna direction of the vehicle terminal installed in the vehicle and handle billing during the non-stop driving after entering the roadside equipment area, and there is a problem that is not based on accurate basis. It is up to the driver to judge and determine the direction of the antenna

Embodiment Construction

[0028] Hereinafter, the specific content of the embodiment of the present invention will be described with reference to the accompanying drawings.

[0029] In addition, in describing the present invention, the same reference numerals are assigned to the same parts, and overlapping descriptions will be omitted.

[0030] figure 1 It is a side view and a top view of roadside equipment structures installed at tollbooths.

[0031] exist figure 1 and figure 2 Among them, in order to be used for the roadside equipment antenna setting that covers the driving lane line through the flyover bridge structure that is set up for the current electronic toll collection system service, on both sides of the flyover bridge, vertical brackets 120 are vertically arranged, and between the vertical brackets A horizontal bracket 125 is installed at the upper position, and the roadside equipment antenna 110 is installed on the upper horizontal bracket 125 . The antenna can be installed vertically...

Abstract

The present invention relates to a room mirror device with an on-board unit (OBE) for dedicated short range communication (DSRC) which installs one or more OBE antennae to match an OBE receiving direction to a transmission beam direction of a main lobe of an RSE base station installed on a toll gate of a highway, and selects an antenna with best receiving power. The room mirror device with an OBE for DSRC comprises: a room mirror housing unit attached to a vehicle by a support; an antenna plate which is mounted on a rear surface of the room mirror housing unit, and arranges a plurality of transceiving antennae for transceiving with road side equipment (RSE); a button and external event input unit to select an operating mode of the antennae; and an information processing module which is included in the room mirror housing unit, and transceives with the road side equipment (RSE) via the transceiving antennae to process a charge by an electric toll collection system (ETCS). The information processing module selects a transceiving antenna with the largest receiving signal strength among the plurality of transceiving antennae to use the selected transceiving antenna to process a charge. According to the room mirror device, an antenna with a high receiving level is selected among a plurality of OBE antennae to always maintain a minimum receiving level required for demodulation and calculate a charge without an error.

Description

technical field [0001] The present invention relates to an electronic toll collection system (ETCS, Electric Toll Collection System) that automatically pays fees by connecting with a dedicated short range communication (DSRC, Dedicated Short Range Communication) technology between a roadside base station (RSE) and a vehicle terminal (OBE) ) in the direction control of the vehicle terminal antenna, and relates to an indoor mirror device equipped with a dedicated short-distance communication vehicle terminal that adjusts the direction of the vehicle terminal antenna in a manner that conforms to the beam direction of the roadside base station (RSE, Road Side Equipment) antenna . Background technique [0002] The electronic toll collection system is a type of intelligent transportation system (ITS, Intelligent Trasport System) service that performs electronic payment of tolls through wireless connection between roadside equipment and vehicle terminals by dedicated short-range co...
