Research And Implementation Of Dry Ice Production Line Computer Control System

Computer control system plays an important role in the information construction process. At present, in order to realize the complex control, a variety of computer control system will coexistence and mutual fusion. In the design of control system, we should carry out the design corresponding system according to the different demands. On the basis of dry ice production control system, this paper describes the control system design and implementation process in detail. The control system is consists of control layer and field layer. Monitoring layer realizes the entire production line control, which is controlled by I PC, the backstage database and configuration software, the field control layer implements data acquisition and the field control of the dry ice production site which is controlled by PLC, field instruments and control valve.This paper focuses on the realization process of monitor layer in this control system, and introduces the database management, the application of configuration software and production of the reports in detail. The dry ice production process focuses on the compression process, dehydrogenation process, purification process and purification process. Automatic control system illustrates the design and implementation of HMI, configuration and organization of the device site, configuration and management of database, method of report printing and the problem of faults. The paper also discusses the problems encountered in the debug process of the control system and concrete solutions.
