【摘要】 针对电力系统中常出现的行人或电力操作人员误入电力危险区域的情形,提出了一种采用微波感应技术实现的语音警示方法,即利用微波感应传感器检测周围空间,中央处理器通过处理微波感应传感器感应信号而控制语音报警电路,从而达到对误入危险区的人员进行语音警示的作用。文中介绍了这种语音报警器的组成、工作原理、使用范围以及推广与更新。更多还原

【Abstract】 In electric power system,passerby or electric power operator frequently goes wrong to electric power danger zone. This paper brings forward a phonetic caution method using microwave induction technology.Microwave induction sensor is used to detect surrounding space,and the signal from microwave induction sensor is processed.The central processing unit can control phonetic caution circuit,then the phonetic annunciator accordingly achieves the phonetic caution effect to passerby or electric power operator who going wrong to electric power danger zone.The composition,working principle,using scope, generalizing and updating of the phonetic annunciator are discussed.更多还原
