摘要
为模拟核电站的公共广播和撤离报警系统、培训员工的操作技能,采用32位低功耗单片机STM32F103、高音质语音芯片ISD4004、定压功放和CAN通信技术设计了公共广播和撤离报警模拟培训系统,模拟实际系统通过广播呼叫站对核电站选定区域或全厂进行广播。首先根据实际系统的功能,提出了模拟培训系统的总体设计方案并介绍其工作原理。然后详细分析了系统硬件的设计思路和方案实现,给出了软件流程图。现场使用结果表明该系统可有效地模拟实际系统,并稳定地工作。
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.
