Problems solved by technology

When the vehicle is passing normally, the power loss of the 5.8G composite card is acceptable. When the road is congested and the vehicle is running slowly, the power consumption of the card is very large, and it is easy for the 5.8G card to fail due to power exhaustion. scrapped

Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] Firstly, due to the communication asymmetry between the 5.8G composite card and the RSU in the prior art, when the distance between the two is relatively long, the RSU may not receive the response signal from the 5.8G composite card. If the interval time between the wake-up signals sent by the roadside unit is set to be small, that is, the wake-up signals are sent more densely, the number of response signals returned by the 5.8G composite card will be mo...

Abstract

The invention relates to a wake-up signal transmitting control method, a path identification method, a controller, a roadside unit and a charging tag. The wake-up signal transmitting control method comprises the steps that interaction information of each roadside unit of an identification station and the charging tag of the passing vehicle is acquired in real time; the congestion state of the current road segment is determined according to the interaction information; and the interval time of transmitting the wake-up signal of each roadside unit is adjusted according to the congestion state. With application of the technical scheme, power consumption of the card can be reduced in case of road congestion and the service life of the card can be enhanced. Besides, there is sufficient time tocomplete transaction because of slow vehicle speed in congestion and the situation of leakage transaction does not occur.

Description

technical field [0001] The present invention relates to the field of intelligent transportation (Intelligent Transportation System, ITS), in particular to a wake-up signal sending control method, path identification method, controller, roadside unit and toll label. Background technique [0002] In the route identification application, for ETC vehicles, the route identification base station writes the route information into the OBU and IC card, while for non-ETC vehicles, a 5.8G composite card is received at the entrance of the toll station, when the non-ETC vehicle passes the route identification At the station, the path identification base station will write the path information into the 5.8G composite card, and when passing through the exit, read the path information, and then charge. However, since the 5.8G composite card is not installed on the front windshield unlike the OBU, after the driver receives the 5.8G composite card, it may be placed anywhere in the car. The a...
