摘　　要：高压电柜自动安全报警器运用超声波发生器向电柜四周发射超声波,测量人或动物离电柜的距离,当被测距离小于最小安全距离时装置报警。文章从硬件电路和软件系统两方面分析了该装置的工作原理,针对超声波受温度影响较大的弱点进行了温度补偿,并且对其它多种发射信号在该装置中应用的可行性做了一定的探讨。The annunciator of automation and safety for high-voltage electric tank used the ultrasonic generator to transmit the ultrasonic around the electric tank, and to measure the distance between electric tank and people or animals. When the distance measured is less than the least safety distance, the device gave an alarm. The paper analyzed the operational principle of the device from hardware connection and software system. Contraposing the foible that ultrasonic is easy to be affected by temperature, the temperature compensation was done and the feasibility of other emission signals applied in this device was discussed.
