并口通信在电力系统谐波测量中的应用

Application of Parallel Interface Communication in Harmonic Measure of Power System

介绍了电力谐波测量系统的设计及实现。针对谐波测量系统的较强控制功能的要求,采用了计算机标准打印机接口进行通信,把上位机的强大计算处理能力与下位机(单片机)的抗干扰及实时控制能力相结合。文中给出了通过计算机标准打印口通信的具体策略及系统的主要硬件模块和软件结构。此谐波测量系统具有实现容易、操作维护方便、成本低、精度高等特点。

This paper first introduced design and implement of harmonic measure system.With the request of control function of harmonic measure system,the system adopted printer interface communication of a computer,and it could effectively complete both the powerful calculation and the antijamming and real time control of single chip computer.The main hardware modules and software configuration were all introduced.The harmonic measure system was implemented and maintained easily,had low cost,high precision and so on.
