摘　　要：当前分布式直流电源远程监控系统预设的功能模块多为目标式,监控效率低,导致远程监控频率大幅度下降,为此提出基于嵌入式单片机的分布式直流电源远程监控系统。根据当前的监控需求,先进行分布式直流电源嵌入式单片机远程监控系统硬件的设计,然后采用多阶的方式提升监控效率,设计多阶嵌入式单片机直流电源远程监控功能模块,并接入直流电源远程监控数据库,完成对系统软件的设计。测试结果表明,针对选定的6个测试区段,经过3个周期的测试,最终得出的远程监控频率均可以达到150 Hz以上,这说明该分布式直流电源远程监控系统更为高效,具有实际的应用价值。The preset functional modules of the current distributed DC source remote monitoring system are mostly set as target type,resulting in low monitoring efficiency and a significant decrease in remote monitoring frequency.Therefore this work designed an embedded microcontroller-based remote monitoring system for distributed DC sources.First,according to the current monitoring requirements,the hardware demand of the system was determined,and a multi-stage approach was adopted to improve the efficiency of monitoring.Then a multi-stage embedded microcontroller DC source remote monitoring function module was designed and connected to the remote monitoring database to complete the design of the system software.The proposed system was indicated,by a three-cycle test,to achieve remote monitoring frequencies above 150 Hz in all the 6 selected sections,and thereby to have potential efficiency and practicability.
