使用单信号传输线实现非电物理量信号群体中众多传感器与测量仪器的连接,是电子技术领域人们多年来致力解决的课题。事实上,离开微机去处理这一问题是极其困难的。但是完全按微机常规的数据通讯方式来处理,仪器系统的成本相当昂贵,不利于推广应用。本文作者另僻蹊径,对多路信号的数据采集,提出了一种数据通讯的新方法,并在一定范围内反复试验,取得了预期的效果。
The use of a single signal transmission line to realize the connection of many sensors and measuring instruments in a non-electrical physical signal group is a subject that people have devoted themselves to solving in the field of electronic technology for many years. In fact, it is extremely difficult to leave the computer to deal with this problem. However, it is completely processed by the conventional data communication method of the computer. The cost of the instrument system is quite expensive, which is not conducive to popularization and application. The author of this article another secluded path, the multi-signal data acquisition, a new method of data communication, and within a certain range of repeated tests, and achieved the desired results.
