The Automatic Batching And Monitoring System Based On VB

The automatic batching and monitoring system is a dynamic.on line dosing system.It enjoys wide application in feedstuff processing,chemical engineering, metallurgical industry,mining,electric power,building material manufacturing and other industries.The research and development of the system is of great significance to improving working conditions,enhancing product quality and manufacture efficiency,perfecting modern enterprise administration system.On the basis of summarization on the application background and development trend of the automatic batching and monitoring system,taking the batching technology as a subject,the paper provides an analysis on the structure and.control principles of the data acquisition,clip and calculagraph.The function requirement of the system is also analyzed in the paper.After these,the paper gives a general design,hardware and software system solutions for the batching and monitoring system,included structure of the device,the hardware circuit of function modules and the soft flowchart of the whole system.The hardware design includes industrial control computer configuration,selection of data acquisition control board type and calculagraph type,design of the power supply and monitoring interface circuit,design of signal processing interface circuit, design of panel control circuit,design of the system alarming,and etc.The software design includes main program design,data-acquisition program design, the data of measurement processing program design,database design,statement generation program design,statement printing program design,and etc.The monitoring System can monitor 12 input and 12 output signals of the automatic batching system and 1 rev signal of motor accurately and duly.At the same time it can monitor 4 temperature and 4 vibration signals of equipment in the automatic batching system,and display them duly by graph.The software is designed with VB 6.0,adopting modular structure.The test result is saved in the database designed by Access,which could carry out inquiry,historical retroversion,statement and print for all test records.The test result of hardware and software shows that the system has steady,reliable operation and is of highly real-time accuracy.
