摘　　要：本系统下位机以STM32F407单片机为控制核心,使用其内部12位ADC,设计了一个2 Mb速率的高速示波器、新型高压大电流脉冲触发电路等,并通过以太网UDP协议把数据传送给工业触摸屏。实现了对采煤机电动机线圈激励冲击,快速波形数据采集,可以清晰显示匝间短路的故障现象,经过实际测试,识别故障效果明显。This system uses STM32F407 microcontroUer as the control core, using its internal 12 bit ADC, designed a high-speed oscillograph, and a new high voltage and high current pulse trigger circuit ,its rate can up to 2Mb rate. It transmits the data to the touch screen through industrial Ethernet UDP protocol. The instrument achieves the excitation and impact of the coal-winning machine＇s electromotor, the fast waveform data acquisition, and can clearly display the fault phenomenon of the inter turn short circuit.

关 键 词：高速示波器 触发电路 UDP协议 激励冲击
