In order to overcome the problems of poor performance of distance detection based on deep learning, vehicle borne ultrasonic ranging system and vehicle borne radar automatic braking system in foggy and high-speed environment, this paper proposes a vehicle distance warning system based on the fusion of LoRa technology and laser ranging technology. The algorithm is established by visibility, speed, speed limit, distance and other factors, and the threshold value of minimum safe distance is set. Then the LoRa wireless network is used to monitor the distance between the front and rear vehicles. At the same time, the intelligent warning can be realized when the dangerous distance is between vehicles, so as to ensure the safety of high-speed driving in foggy days. The experimental results show that the system has the characteristics of wide protection range, low power consumption, high reliability and low cost.
