Abstract

The invention discloses a safety pre-warning system and method for a tortuous road in a mountainous area. The safety pre-warning system for the tortuous road comprises a mountainous area tortuous roadside safety pre-warning system and a mountainous area tortuous road vehicle-mounted pre-warning system which are matched with each other, wherein the mountainous area tortuous roadside safety pre-warning system comprises a vehicle licence plate recognition unit, a vehicle positioning signal receiving unit, a tortuous road edge safety distance monitoring unit, a tortuous road vehicle status monitoring unit and a data processing unit; and the mountainous area tortuous road vehicle-mounted pre-warning system comprises a micro-processing unit, a GPS positioner, an external GPS positioning signal receiver, an acceleration sensor, a vehicle-mounted end short-distance data communication module, an LED display, an alarm and a vehicle-mounted end external memory. According to the provided technical scheme, vehicles passing through the tortuous road can be pre-warned in advance according to actual conditions of the tortuous road in combination with vehicle conditions running on the tortuous road, so that more reaction time is bought, and the probability and the severity of accidents are greatly lowered.

Description

Technical field [0001] The invention relates to the technical field of road safety early warning, in particular to a safety early warning system and method for multi-curved road sections in mountainous areas. Background technique [0002] With the improvement of public consumption level, more and more people choose to drive or travel by car, and then there are safety issues on the road, especially in the mountainous areas with a high probability of accidents, and once an accident occurs , The consequences are more serious. There are two main reasons for traffic accidents on bends: the first is speeding, and the second is due to the complexity of the bend or the surrounding mountains and trees, resulting in restricted vision or blind spots. These two reasons will greatly shorten the reaction time of the driver when an accident is about to occur, and this time is often less than the normal reaction time of a person. The actual situation is that the accident has occurred before th...
