Study Of Automatic Weighing System

On the basis of researching on the progress of technology of weighing, this paper discusses the development of automatic weighing system which has a complete function.With the progress of automation in industry and modernization in management, there is much progress in weighing online, fast and dynamic weighing and system of weighing. Adopting newer technology, developing diversified automatic weighing system, improving accuracy and enhancing network function are emphasized in every country nowadays.Besides the function of collecting, processing, displaying and communicating of data about weight, the automatic weighing system can also save data in database and print data in report form. It can also visit and query the records in database and capture the image of truck by pick-up head and save it in database in bitmap form. Use the image to verify whether the code of truck inputted is true. The process of realization of functions is: When the data of weight is received by PC, PC will call the function of adding record, and then the truck's code is inputted and the image of truck is automatically captured . Finally, all data are stored in database. And the system completes the function of automatic weighing. At the same time, the functions of this system are the presupposition of realizing network function.The programming languageused in this paper is Visual C++6.0 which is used to program database code and so on. This language provides many good tools and functions, so that it improves the developing efficiency. The software programmed with it can realize high running efficiency and high reliability. Moreover, C51 is used to program data-collecting codes in singlechip.
