BASED ON PLC CONTROL SYSTEM OF INTELLLIGENT PRESURE VESSELTIGHTNESS TEST DEVICE

ABSTRACT
                                      
The topic mainly completes PLC control system for intelligent pressure tightness test equipment pressure vessel design. This article firstly brief descriptions the background of the subject and status of the current pressure vessel, then presents my own program. Then a series of descriptions about the subject are introduced, first starts with the whole design, and gives the relevant design diagram, and specifically introduces some of the key devices; In terms of software describes some of the key program about lower computer, and represents the thinking and basis for solving problems; About the PC, gives a brief introduction about Configuration and process control of the host computer. Finally, I do a simple debugging and analysis after the topic completed, the results prove that the software system design and hardware system design is reasonable, and the purpose and the required functions can be completed.

KEY WORDS: Air tightness test bench; PLC control system; host computer; pressure sensor
