The Design of the Loss-in-Weight Weighing Controller

Abstract:

In order to achieve higher precision, reliability and stability, lower cost and power consumption, friendly user interface and network functions, loss-in-weight weighing Controller based on ARM9 and Windows CE is designed for controlling dynamic real time batching equipment. This paper first introduces the working principle and architecture of the embedded Controller, then explains hardware system component and design of software system of the Controller, developed on Platform Builder 5.0. The paper pays more attention on the application layer development. Subfuctions of application software are introduced and working flow chart of main modules is given. Double incremental PID algorithm used by the system is presented to achieve the highest accuracy in the shortest possible time. The high precision 0.1% can be achieved, and Controller products are widely used in the metallurgy, chemical industry.
