摘要

The paper determines the function and performance indicators of the standard signal generator of high voltage circuit breaker according to the actual needs of the online monitoring equipment in high voltage circuit breaker. After the actual waveform acquisition and digital signal processing, the true and accurate action waveform of high voltage circuit breaker were obtained, which provided a reliable basis for the standard signal output. From the two aspects of the software and hardware, the design and implementation of the standard signal generator of high voltage circuit breaker have been described in detail. The hardware used the STM32 family of processors based on the Cortex-M3 core, and the software used an embedded real-time operating systemμC/OS-II. After the actual test, the system functionality and performance fully achieve the desired design.%　　根据高压断路器状态在线监测设备的实际需求，确定了高压断路器标准信号发生仪的功能和性能指标。经过实际波形采集和数字信号处理，获得高压断路器真实准确的动作波形，为标准信号的输出提供可靠依据。从嵌入式软件和硬件两个方面详细介绍了高压断路器标准信号发生仪的设计与实现，硬件使用基于Cortex-M3内核的STM32系列处理器，软件使用嵌入式实时操作系统μC/OS-Ⅱ。经过实际测试，系统功能和性能完全达到预期设计。
