Design of the Water-Immersing Large Injection Sterilization Cabinet Control Systerm Based on PLC Technology

This paper introduces PLC and the application of tonch panel in the control system of the water-immersing large injection sterilization cabinet ,and the control demands which should be satisfied ,as well as the configuration of hard- ware design of the system. This paper describes the design scheme of system and the hardware structure of various parts in detail ,the design and development of software and peripheral circuits is carried out. Then aimed at work circumstance ,makes a further improvement and reduces wiring of the system .This design has the advantages such as small investment and control stability ,so it has a better promotional value. The practical application shows that the system has the advantage of fine anti-jamming ,high automation and strong practicability.
