摘要:采用PLC和触摸屏的常规控制方案,低成本高性能地完成了对工控系统中高速采集到的数据进行保存和分析,解决了触摸屏数据库保存数据速率低(2次/s)的问题,使每秒钟可以保存多达20个数据,并且增加了数据库保存数据的总数.该系统在某军工企业中应用于对膜片性能的测试,其精度达到了0.5%以上.
关键词: 触摸屏, 数据保存, 性能测试, 低成本, 工控系统
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
