The invention claims to protect a mountain road intelligent early warning embedded guardrail device, and belongs to the field of vehicle collision early warning. The device comprises a guardrail collision fault reminding device, a LoRa base station, a cloud, a monitoring center and a nearby vehicle GPS terminal. The guardrail collision fault reminding device comprises a solar power supply module,a single chip microcomputer module, a collision sensor module, a wireless transceiving module, an LED caution light module and a buzzer warning module. If it is judged that an impact force generated by a vehicle during the collision with a mountain road guardrail exceeds a certain threshold, the information obtained by a sensor is transmitted to the LoRa base station through LoRa wireless transmission to be uploaded to the cloud, the fault information is transmitted to a monitoring center for alarm, and the cloud simultaneously uploads the faulty road section information to the nearby vehicleGPS terminal. After receiving the fault information, the LoRa base station turns on LED caution lights and early warning buzzers of a fault device and nearby devices thereof to remind the nearby vehicles to avoid the faulty vehicle in time, so that serial accidents in dangerous road sections and the situation of untimely accident rescue can be reduced.

The invention discloses an expressway vehicle intelligent prompting and guiding system and method. An environment monitoring module is used for monitoring the expressway environment information and transmitting the monitored environment information to a data processing module, the data processing module is used for setting a threshold, storing and receiving the environment information sent by theenvironment monitoring module, selecting a corresponding control strategy after comparing the received environment information with a set threshold value and transmitting to a main control module, andthe main control module controls the light-emitting delineators which are arranged on an expressway at intervals and can emit multiple colors to emit different colors for vehicle induction reminding.By utilizing the light-emitting delineators which are arranged on the expressway and can emit multiple colors, and combining the multi-data fusion analysis and decision of the expressway environmentinformation, the intelligent active light-emitting induction is carried out on the drivers driving on the expressway, the alertness of the drivers is improved, the purpose of reducing the accident rate of the expressway is achieved, and then the safety of a traffic system is improved.

Expressway vehicle intelligent prompting and guiding system and method

The invention discloses a mountainous-area two-lane curve active early-warning anti-collision guard bar and a rear-end collision early-warning method. Through the anti-collision guard bar, on the condition that the linear change of a mountainous-area curve is dramatic and the visibility range is poor, vehicles in two two-way lanes can be monitored in real time, the dynamic position change of all the vehicles is monitored, and then dangerous conditions which possibly occur can be subjected to early warning. The method comprises the steps of prompting of the running conditions of the vehicles ofopposite-direction lanes, early warning of rear-end collision of the front and rear vehicles, and prompting early warning through an acousto-optic system. By means of the mountainous-area two-lane curve active early-warning anti-collision guard bar and the rear-end collision early-warning method, main traffic risks which possibly occur in the curve can be subjected to all-directional and systematic advance early warning, and thus the occurrence of accidents is reduced; meanwhile, active early warning and passive anti-collision facility integrated design is conducted, and double guarantees ofthe traffic safety are achieved.
