摘　　要：脉冲发生器广泛应用于电力电子、运动控制、车辆控制等场合,是设备驱动和控制的基础通用部件,但目前脉冲发生器的网络通信能力较弱,无法满足高速控制需求,难以集成到智能制造系统。针对该问题,基于实时工业以太网EtherCAT和龙芯LS1C处理器设计了一种脉冲信号发生器,通过EtherCAT实现高速、实时通信功能,并可灵活地配置成链形和环形拓扑结构。脉冲信号发生器可工作在4种工作模式,满足多种控制需求。最后,通过实验测试了脉冲发生器的工作模式和精度。The pulse generator is the basic equipment for device drivers and control,widely used in many occasions,such as power electronics,motion control,vehicle control,etc.However,the used pulse generator is weak in communication,which cannot meet high-speed control requirements or be used in the intelligent manufacturing application.To solve the above problem,this paper designed a pulse generator with real-time industrial ethernet EtherCAT and Loongson processor LS1C.The designed pulse generators can form the daisy chain and ring topology by EtherCAT.And the pulse generator is very flexible and suited for many different applications with its four operation modes.Finally,experiment results are presented to demonstrate the operation modes and performance.
