Title The Software Design Of Multi-channel Voltage Monitoring System Based On TMS320LF2407A
Abstract
With the increase of the electrical equipment, the expansion of power and influence produced by the equipment fault is greater, there has been a corresponding increase in users' requirement of power supply reliability, the electrical equipment online monitoring system arises at the historic moment. Online monitoring system can make real-time monitoring of the voltage amplitude of signal, electrical equipment take measures immediately to deal with the voltage fluctuation, so that we can guarantee the safety of them.
This article based on high performance digital signal processor (TMS320LF2407A) as the core, construct the multiplex voltage monitoring system. In this paper, through the simple introduction of multiplex voltage system overall design, hardware part of the composition and function, leads to the program design of PC software part. PC software is written by Visual c + + , primarily through it realizes multi-channel real-time display of voltage, makes processing of interference and displays voltage conditions. In the end, the realization of the function of the program was tested.

1.1 电压监测的研究背景及意义
城市面积的扩大,人口总量的增多,新兴科技电力电子化的愈加普及,工业系统工程标准的精细化,自动化与网络化的提高,都意着发电量的加剧,电力系统的扩大化以及更重要的——电能质量要求的提高。但因为大量非线性与冲击性负荷的投入,易导致谐波产生,电压波动与波形畸变等等问题的发生[1]。要保证稳定,安全,高质量的电能,需求对波形瞬时变化的捕捉监察与检测;足够高的频率得到合适数量的采样样本进行分析;具有能力分析辨识数据及控制等[2]。 基于TMS320LF2407A多路电压监测系统软件设计:http://www.751com.cn/zidonghua/lunwen_19054.html
