摘　　要：我国广播电视节目的规模越来越大,传播形式也越来越多,为了保证节目的安全播出,文章提出了一种基于STM32的HCO3901自动切换语音报警系统设计方法。首先将HCO3901自动切换器的GPI信号提取出来,作为STM32的输入信号,检测这个GPI信号输出一组控制信号,触发语音模块进行报警。该语音报警系统经过实际测试,能够及时发现切换器的切换动作,从而提醒工作人员对异常信号做出及时处理,减少播出事故的发生,在播出系统中具有重要的应用价值。Radio and television programs in China are growing in scale and forms of transmission. In order to ensure the safe broadcasting of China Radio and TV programs, this paper proposes a design method of HCO3901 automatic switching voice alarm system based on STM32. Firstly, the GPI signal of HCO3901 automatic switcher is extracted and used as the input signal of STM32. Then, the GPI signal is detected to output a group of control signals, so as to trigger the voice module to realize the voice alarm. After actual testing, the voice alarm system can find out the switcher’s switching action in time, so as to remind the staff to deal with the abnormal signal in time and reduce the occurrence of broadcasting accidents, which has important application value in the broadcasting system.
