Vehicle-mounted traffic signal combined identification system

Abstract

The invention discloses a vehicle-mounted traffic signal combined identification system; a signal emitter is pre-buried on a lane, and connected with a traffic signal lamp controller so as to emit a traffic information signal of the present lane or directly emit a geographical information signal of the signal emitter located position; the bottom of the vehicle is provided with a signal receiver capable of receiving the signals emitted by the signal emitter; a signal processor connected with the signal receiver is arranged in the vehicle, and connected with a vehicle-mounted prompt unit. The advantages are that a non-networked traffic signal can be processed in the vehicle through the signals emitted by the signal emitter pre-buried in the ground, thus prompting the traffic signals of the present only lane in real time, and preventing the problems that the traffic signal cannot be identified due to truck blocking and severe weathers such as sunlight low irradiation and wind and rain andmist and fog.

Description

technical field [0001] The invention relates to the technical field of traffic lights, in particular to a vehicle-mounted traffic signal recognition system. Background technique [0002] As the traffic becomes more and more convenient and the number of cars on the road is increasing, traffic lights are particularly important when crossing intersections. Generally speaking, the driver can clearly judge the traffic light signal at the intersection, so as to choose whether to stop or go straight.

Or overtaking incident, this brings very big trouble to traffic policeman and drivers, sometimes even can cause loss of life and property to people. The date of the announcement is May 18, 2011, and the patent with the announcement number CN201838191U discloses a vehicle traffic light recognition device...

Problems solved by technology

GPS cannot accurately determine the location on or under the elevated

Based on the above facts, there will be the following disadvantages: culverts and tunnels are completely useless. If there are multiple functions in one lane (turn left and go straight, turn right and go straight), there are still lanes in big cities that change direction according to time periods, and the system may Let the driver make mistakes in judgment, and the existence of elevated roads is more likely to cause false alarms
