摘　　要：介绍了在储罐测量系统中使用软件UART的实现方案。使用该方案实现的软件UART,不但通信可靠性高,程序的移植性好,而且因无需选用多串口单片机,降低了系统硬件的开发成本。This article introduces the implement solution of software UART which used in Storage Tank measure system. This software UART based on PCA. The software UART that implemented by this solution, Correspond credibility not only high, the transplantation of program good, and didn＇t need to choose use multi-UARTs Single-Chip computer,lowered the development cost of the system hardware.
