Abstract: A general control plan based on PLC and the touch screen fulfills the task of data storage and analysis in industry control system with lower cost and higher performance and the data acquisition is in the high speed.The touch screen database ‘problem of lower velocity (2 times per second) is solved in the process of data storage.Not only the speed of preserving data can reach 20 times per second,but also the total amount of the database storing data is increased.The system has been applied in the diaphragm performance test system in a military enterprise,and the precision has reached more than 0.5%.

Key words: touch screen, data storage, performance test, lower cost, industry control system
