随着现代工业的快速发展,在化工生产领域中,自动化系统正在得到越来越广泛的应用。为了加强化工生产工艺的安全性和稳定性,工业生产中对化工自动控制和参数检测等提出了更高要求。PLC系统(即可编程序控制器)在化工行业生产过程中控制系统的设计、机械安全的保护等方面有着十分重要的作用。目前,我国化工的大多数自动化控制装置仍然采用常规的操作系统,导致90%以上装置的真正潜力没有发挥出来。
With the rapid development of modern industry, automation systems are getting more and more widely used in the field of chemical production. In order to strengthen the safety and stability of the chemical production process, higher requirements are put forward on chemical industry automatic control and parameter testing in industrial production. PLC system (that is, programmable logic controller) in the chemical industry in the production process control system design, mechanical safety protection and so has a very important role. At present, most of China’s chemical automation devices still use the conventional operating system, resulting in more than 90% of the true potential of the device did not play out.
