概述遵循毛主席关于“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。因此,人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的教导。我国在工业自动化领域内如何赶上和超过世界先进水平是关系到实现四个现代化的重要问题。六十年代以来,随着电子计算技术的迅速发展,国外在工业控制机应用方面取得了进展。特别是在石油化工、合成氨生产过程中的应用占了相当大的比例。但是,与军事和空间技术领域内计算机应用发展速度相比,不能认为是令人满意的,除了在一些专门的 In accordance with Chairman Mao’s statement that “mankind always develops continuously within the scope of the struggle for production and scientific experimentation and nature will always develop ceaselessly and will never stop at a level. Therefore, mankind always needs to sum up his experience and experience Found, invented, created, advanced ”teaching. How to catch up with and surpass the advanced world level in the field of industrial automation in our country is an important issue that concerns the realization of the four modernizations. Since the 1960s, with the rapid development of electronic computing technology, foreign countries have made progress in the application of industrial control machines. Especially in the petrochemical, ammonia production process accounts for a large proportion. However, it can not be considered satisfactory compared to the rate of development of computer applications in the field of military and space technology, except in a few specialized
