摘　　要：WinCC可使用MSComm控件通过串口与单片机进行通讯。单片机的数据采集和发送速率较高,而相比于单片机,WinCC的通讯速率和归档速率均较低,正常情况下无法匹配。在针对WinCC与单片机在高速数据传输方式进行研究后,提出了采用数据缓存技术,整体打包发送的方式,间接提高WinCC与单片机的数据通讯速度。经实际测试,可在保证数据正确率的前提下,将WinCC与单片机单条数据的传输时间缩短为10 ms。WinCC can use MSComm control to communicate via serial port with MCU. There′s a higher rate of data collection and send,and the WinCC′s rate of transmission and filing rate is lower than the single chip,and it′s not a normal match. After studying the high-speed data transmission mode of WinCC and single-chip microcomputer,the method of using data caching technology to package and send the whole package was put forward,which could indirectly improve the speed of data communication between WinCC and MCU. After the practical test,the transmission time of single data of WinCC and MCU could be shortened to 10 ms directly under the premise of ensuring the accuracy of the data.
