摘要
针对现有的有源滤波器APF(active power filter)存在数据存储量少、数据处理能力弱,远程监视能力差等问题,对APF运行中信号采集、处理、传送,显示等方面进行了研究,对实时运行监视系统的设计方法进行总结,设计了APF运行在线监测系统。该系统采用低功耗的STM32F103RBT6芯片作为信号采集处理控制器,利用STM32开发板外设的功能模块进行数据的传输、存储,并利用开发板标准通信接口实现了RS485远程通信,从根本上克服了APF数据存储量小及远程监测能力弱的问题。实验运行结果表明,此系统对APF数据的采集,处理的能力较于APF本身大为加强,数据存储量大幅度提升,远程监测效果好,并且该系统操作简单,成本低,具有较好的应用和推广价值。
In view of the problem that the existing APF（active power filter）has less data storage,weak data processing ability and poor ability of remote monitoring,the signal acquisition,processing,transmission,display and so on of the APF in the operation are studied.The design method of on-line monitoring system is summarized.The real-time monitoring system for APF operation is designed.This system adopts the low-power STM32F103RBT6 chip as the signal collection and processing controller,using STM32 development board peripheral function module for data transmission,storage,and using the advanced standard communication interface on development board to realize RS485 remote communication.Thus the problems that APF data storage capacity is small and remote monitoring ability is weak are fundamentally overcome.The experimental simulation results show that this system has greatly strengthened the ability of APF data acquisition and processing,significantly enhances the data storage and remote monitoring effect is good.The system operation is simple and has low cost,thus it has good application and popularization value.
