摘要
针对高重频脉冲功率电源放电异常的现象,设计了基于CAN总线的对脉冲电源模块充放电以及数据采集的分布式控制及在线电流检测装置。采用ARM9处理器作为设备主节点,基于STC系列IAP15W4K60S单片机设计子控制器节点,利用Linux下Socket、CAN总线通信原理实现对多个脉冲电源模块可靠快速控制并能针对放电电流采样并进行故障诊断。结果验证表明该装置能在放电异常时终止放电流程并告警;正常放电时能在1 s内完成故障诊断及系统复位并最终实现10次/min高重频放电,过软硬件调试,验证了系统的可行性。
Aiming at the abnormal discharge of the high-repetition pulse power supply,a distributed control and online current detection device for charging and discharging the pulse power module and data acquisition based on the CAN bus is designed.The ARM9 processor is used as the main node of the device,and the sub-controller node is designed based on the STC series IAP15 W4 K60 S single-chip microcomputer.The principle of Socket under Linux and CAN bus communication is used to achieve reliable and rapid control of multiple pulse power modules.The device analyzes the discharge current of the power module,and terminates the discharge process and gives an alarm when the pulse power module discharges abnormally;under normal conditions,it can achieve high repetitive frequency discharge ten times per minute.After software and hardware debugging,the feasibility of the system is verified.
