基于无线收发的紧急路况救援提示装置

Emergency road condition rescue warning device based on wireless transceiver

近年来,救援车辆被堵事件时有发生,路段车辆无法提前得知救援车辆经过,导致避让缓慢。针对道路中车流高峰时期,如何保证救援时效性的问题,文章提出了一种基于单片机及CC1125芯片的无线信号收发器的设计。文章提出发射器总体设计的方案,在方案的基础上分别从硬件及软件角度阐述了中远距离收发无线信号的实现原理。经过收发通信传输稳定性的测试仿真实验,最终表明该设计传输稳定性高,救援效率有了一定的提高,对帮助紧急救援车辆快速到达救援地点具有重要的意义。

In recent years,rescue vehicles have been blocked from time to time,and the vehicles on the road cannot know in advance the passing of rescue vehicles,resulting in slow avoidance.Aiming at the problem of how to ensure the timeliness of rescue during the traffic peak period,a wireless signal transceiver based on single chip microcomputer and CC1125 chip is proposed.Firstly,the overall design scheme of the transmitter is proposed,and secondly,the realization principle of transmitting and receiving wireless signals from the hardware and software perspectives is expounded on the basis of the scheme.Through the test and simulation experiment of the transmission stability of sending and receiving communication,the final result shows that the design has high transmission stability,and the rescue efficiency has been improved to a certain extent,which is of great significance for the relief of emergency rescue vehicles stuck on the rescue road.
