Vehicle-mounted traffic signal safety warning system

Abstract

The invention discloses a vehicle-mounted traffic signal safety warning system, which comprises a sending assembly and a receiving assembly. The sending assembly is formed by a signal acquisition unit, a signal sending unit and four directional transmitting antennas. The input end and the output end of the signal acquisition unit are electrically connected with a traffic signal lamp electric control loop and the signal sending unit respectively; and the signal sending unit is electrically connected with the directional transmitting antennas. The receiving assembly is formed by a receiving antenna, a signal receiving unit, a decoding unit and a voice broadcast unit. The receiving antenna is electrically connected with the signal receiving unit; the signal receiving unit is electrically connected with the decoding unit; the decoding unit is electrically connected with the voice broadcast unit; and the voice broadcast unit is electrically connected with a loudspeaker. The system can enable drivers to accurately know intersection situations under the condition where traffic light conditions cannot be judged due to blockage of sight and the like, thereby improving intersection traffic capacity and safety coefficients.

Description

technical field [0001] The invention relates to a traffic system, in particular to a vehicle traffic signal safety warning system. Background technique [0002] Traffic lights are necessary equipment to ensure the normal passage of traffic at intersections. However, in rainy, snowy, foggy and other weather, because the intersection is far away from the traffic lights, it is often difficult for the driver to distinguish the correct display of the traffic lights. At this time, it is easy to stop. If you don't stop, you don't go on the line, which can easily cause traffic jams or safety accidents; when driving, the driver often judges whether to accelerate or decelerate according to the remaining time of the traffic light. Slow down so that you can pass through the green light directly when you arrive at the intersection, and avoid parking and then driving in gear. However, you often see some street lights on the road that only display simple traffic light conditions, but do no...

[0002] Traffic lights are necessary equipment to ensure the normal passage of traffic at intersections. However, in rainy, snowy, foggy and other weather, because the intersection is far away from the traffic lights, it is often difficult for the driver to distinguish the correct display of the traffic lights. At this time, it is easy to stop. If you don't stop, you don't go on the line, which can easily cause traffic jams or safety accidents; when driving, the driver often judges whether to accelerate or decelerate according to the remaining time of the traffic light. Slow down so that you can pass through the green light directly when you arrive at the intersection, and avoid parking and then driving in gear. However, you often see some street lights on the road that only display simple traffic light conditions, but do not display the remaining time. Drivers cannot judge the time to change lights For example, when a red light is displayed, even if there are only a few seconds left, it can turn into a green light, but the driver can only stop and then start again when he cannot judge the remaining time, which increases the difficulty of driving. In view of this, the applicant has designed a A safety warning system that enables drivers to effectively grasp the status of traffic lights ahead in any weather and street lights
