摘　　要：光伏发电监测系统通信必须快速可靠,因此采用了差错控制。分析了CRC循环冗余校验的差错控制原理,给出了算法的程序流程图,着重介绍了基于图形化编程的LabVIEW语言环境下的查表法校验程序,程序已应用于独立光伏发电实时监测系统中。现场应用和实验表明,该系统具有较高的数据可靠性和较强的环境适应性,可广泛应用于基于LabVIEW的监测系统中。The purpose of communication in monitoring system is to send information reliably and fast.The communication systems adopt error-control.This paper presents error-control principle of CRC（cyclical redundancy check）,gives the CRC-16 algorithm software flow chart,designs the software procedure using LabVIEW language,and finally makes a confirmation in a real-time photovoltaic monitoring system based on LabVIEW.Practical applications and experiments show that the system has higher system reliability,stronger site environmental adaptability,and their application fields were extended.
