Abstract: As a discrete production unit，mobile emulsion explosive trucks are widely used in blast⁃ ing sites of open-pit mines，but they are major hazard source equipment，isolated from the existing infor⁃ mation monitoring system，and have always lacked effective safety supervision methods. In order to improve the current situation of safety protection of mobile emulsion explosive trucks，the functions of the monitor⁃ ing system are designed from the aspects of control system monitoring，video monitoring，and safety opera⁃ tion monitoring by studying the principle of vehicle safety risk. Based on the establishment of the improved cloud monitoring system architecture，the data and video information of emulsion explosive trucks are gath⁃ ered in the edge cloud，and the government affairs cloud is connected through the wireless 4G private net⁃ work to realize the cloud data storage and operation configuration of the monitoring system. The cloud ser⁃ vice technology of building edge cloud-government cloud is proposed，and the second-level monitoring and early warning technology is introduced. The establishment of the cloud monitoring system can bring ex⁃ plosives mixed trucks into the scope of safety supervision，which is of great significance for daily operation monitoring and early warning，scheduling management and risk analysis.
