Design of Public Broadcasting and Evacuation Alarm Simulation Training System Based on CAN

In order to simulate the public broadcasting and evacuation alarm system in the nuclear power plant and train operators,32-bit low-power microcontroller STM32F103,high audio quality voice chip ISD4004,constant voltage power amplifier and CAN communication technology are adopted to design the public broadcasting and evacuation alarm simulation training system which simulates the actual system to broadcast in selected ranges of the nuclear power plant or the total plant through broadcast call stations.Firstly,according to the function of the actual system,overall design scheme of the simulation training system is put forward and its working principle is described.Then,design ideas and scheme implementation of the system hardware are analyzed in detail,and the software flow chart is given.Field operation results show that the simulation training system can simulate the actual system effectively,and can work steadily.
