| Abstract: | 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 s... |
