Design of Early Warning System of Robot for Monitoring Agglomerate Fog on the Highway Based on Beidou Short Message and IOT

Aiming at the traffic safety problem caused by sudden agglomerate fog on the highway, this paper designs an early warning system of the robot for monitoring agglomerate fog on the highway based on Beidou short message and MQTT protocol. This system monitored environmental parameters such as visibility, location information, temperature and humidity in real time by the robot for monitoring agglomerate fog on the highway, and adopts the Beidou short message and MQTT protocol dual-channel communication mode to achieve two-way data communication with the cloud platform and server. The problem of data transmission loss caused by no mobile communication network is solved. Use the Internet of Things cloud platform and WEB application development technology to realize a system with the functions of monitoring data visualization, data monitoring and remote control of robot movement. The experimental results show that the communication that data interaction and remote control between the cloud platform and the robot is stable in the system, and the early warning of the level of fog is timely and effective, which improve the accuracy of monitoring agglomerate fog with broadly application foreground.
