摘　　要：赛车是一项极其危险的运动,大赛规定每一辆赛车都要有一套安全系统,包括一个远程遥控急停装置,其主要功能为在紧急情况下控制车辆及时制动。本文设计并实现了一套基于LoRa通信技术的远程遥控急停系统,系统由遥控端和接收端组成。通过调查和查阅文献得知,现有的车辆远程遥控急停系统存在连接不稳定和延迟较高的问题。本文旨在解决遥控系统连接不稳定和延迟较高的问题。并且还具备手动调频,自动跳频,以及数据帧内容校验,提高了系统的抗干扰性能。经实验表明:系统可实现的通信距离在1.55 KM,且通信延时在220 ms以内。系统在无人车测试远程制动等场景中具有广泛的应用前景。Racing is an extremely dangerous sport. The competition stipulates that every racing car should have a set of safety system, including a remote control emergency stop device, whose main function is to control the vehicle to brake in time in an emergency. In this paper, a remote control emergency stop system based on LoRa communication technology is designed and implemented, which is composed of remote control terminal and receiving terminal. Through investigation and literature review, it is known that the existing vehicle remote control emergency stop system has the problems of unstable connection and high delay. This paper aims to solve the problems of unstable connection and high delay of remote control system. It also has manual frequency modulation, automatic frequency hopping and data frame content verification, which improves the anti-interference performance of the system. Experiments show that the communication distance of the system is 1.55 KM, and the communication delay is less than 220 ms. The system has a wide application prospect in unmanned vehicle testing remote braking and other scenarios.
