单板微型计算机由于其结构简单、成本低廉,在生产过程控制和数据采集处理方面有了较多的应用。但就目前国内很普及的TP801等型号的单板机来看,实际使用时还存在一些不足之处。我们在将其用于生产过程控制时作了相应修改和补充。本文仅介绍我们在扩充读写存贮器时采用的方案。 工业生产过程控制非常需要预先设定一批工艺控制参数和各种初始数据,这些参数、数据在批量生产时往往保持不变或仅作少量修改。为了尽量减少操作工人的操作步骤,这些数据宜一次性保存在读写存贮器 Single-board microcomputer due to its simple structure, low cost, in the production process control and data acquisition and processing have more applications. But at present the very popular TP801 and other models of single-board machine point of view, there are still some shortcomings in the actual use. We made the corresponding changes and additions when it was used in the production process control. This article describes only our expansion of read-write memory used in the program. It is very necessary to pre-set a batch of process control parameters and various initial data for industrial process control. These parameters and data often remain unchanged or only a small amount of changes are made in mass production. In order to minimize the worker’s steps of operation, these data should be stored in a one-time read and write memory
