摘要
稳定可靠的上下位机通信程序是声波飞行时间测量系统实现声波飞行时间准确测量的关键。为此研制了基于VC 6.0的上下位机通信程序。文中详细介绍了该通信程序的设计与实现过程 ,给出了上下位机通信流程图及相应的主要通信程序。实验结果表明该通信程序能够较好地实现声波飞行时间测量系统中下位机和上位机之间的通信 ,系统性能稳定 ,满足声波飞行时间测量系统的通信要求。
The stable and reliable serial communication program between PC and single-chip microcomputer is the key to measure the acoustic wave flying time accurately.We designed a communication program based on VC6.0.It introduced the design and realization of communication program in details and showed the main program of serial communication and corresponding software chart. The experiment results show that the program can well realize the serial communication between PC and C8051F020 (single-chip microcomputer). The system is stable and it can satisfy the requirement of acoustic wave flying time measurement.
