摘要
给出了一种有效、简便的数据采集终端,它利用一个从单片机作扩展的RS232通信口,实现了与仪表或设备之间的通信.介绍了两单片机之间进行数据交换与采集的硬件与软件设计.通过长期测试与现场应用,证明了本通信数据采集终端设计是可行的,具有进一步推广应用价值.
A efficient and simple data acquisition terminal which realizes data communication between the expanded serial communication port and instruments by using a slave single-chip computer as an expanded RS232 series communication port is given in this paper. The hardware and software designs of data acquisition and transfer between two single-chip computers are presented. The measurement and application results show the correctness of this design.The data acquisition terminal is worth spreading .
