一前言 目前我国生产过程程序控制大部分采用TCA-01碳膜任意程序给定仪。随着电子技术的发展,特别是大规模集成电路技术的发展,上述程序给定器无论从精度和操作上都感到有些不足。根据目前我国的技术水平,生产过程广泛采用计算机控制还需要一个过程。长期来用TCA-01碳膜程序给定仪加上DDZ仪表组成的单参数程序控制系统较多,许多用户不但有现成的控制仪表,且对系统也比较熟悉。从这种现状出发,我们研制了以CPU控制的软件程序给定器来代替TCA-01程序给定仪。它既具有计算机控制的某些特点,又可以充分利用企业中已有的控制仪表来组成程序控制系统,它对于我国工业企业中生产过程单参数控制系统具有承上启下的作用。
A preface At present, most of our production process control using TCA-01 carbon film arbitrary program given instrument. With the development of electronic technology, especially the development of large-scale integrated circuit technology, the programmer mentioned above feels some deficiencies in accuracy and operation. According to the current level of our country’s technology, extensive use of computer control of the production process also requires a process. Long-term use of TCA-01 carbon film programmer plus DDZ instrument composed of single-parameter program control system, many users not only have ready-made control instruments, and the system is also more familiar with. Starting from this situation, we developed a CPU-controlled software programmer to replace the TCA-01 programmer. It not only has some characteristics of computer control, but also can make full use of the existing control instruments in the enterprise to form a program control system. It has the function of single parameter control system in the production process of industrial enterprises in our country.
