Solar energy geomagnetic induction road sign and vehicle dynamic trail display system and method

Abstract

The invention relates to a solar energy geomagnetic induction road sign and a vehicle dynamic trail display system and method. The solar energy geomagnetic induction road sign comprises at least one geomagnetic sensor, a luminous body, a processor and a power supply module, wherein the processor is connected with the geomagnetic sensor, the luminous body and the power supply module; the power supply module is used for supplying electricity to other modules in the solar energy geomagnetic induction road sign; the geomagnetic sensor is capable of detecting geomagnetic disturbance caused by the passing of a vehicle and outputting a detection result to the processor; the processor ensures that a vehicle passes a position, where the solar energy geomagnetic induction road sign is arranged, and then the processor turns on the luminous body and lasts the turn-on for a period of time. By adopting the solar energy geomagnetic induction road sign, transient passing of a vehicle in each lane can be effectively detected and occupying of lanes can be effectively marked, thus traveling trails of vehicles are displayed in a low-visibility environment according to the lanes; therefore, effective guide and warning are provided to rear traveling vehicles, and further, occurrence of traffic accidents in the low-visibility environment can be effectively prevented.

Description

technical field [0001] The invention relates to a lane occupancy warning technology using solar geomagnetic induction road signs, in particular to a solar geomagnetic induction road sign that actively emits light and dynamically displays vehicle trails in a low-visibility environment, and a corresponding vehicle dynamic trail display system and method. Background technique [0002] Rain, snow, fog, haze and other weather will reduce the visibility of the atmosphere. When the vehicle is driving in a low-visibility environment, due to the poor visibility of the distance, the safety preview distance is insufficient, and it is difficult to detect whether there is a car in the front lane. Especially when there is a cloud of fog, it is more likely to cause rear-end collisions due to line of sight faults, and it is especially prone to major traffic accidents. [0003] According to statistics, traffic accidents caused by thick fog and other bad weather account for more than 1 / 4 of t...
