In this paper, a new high-speed moisture determination balance based on the loss on drying method and the adaptive data fusion theory with shift sampling method is proposed. Consisted of the infrared oven and the electronic balance, the new moisture balance can precdict the sample's moisture content with high accuracy while the sample is still under drying. So it can solve the contradiction between the speed and the accuracy of the moisture measurement for a long timeThe traditional method to determine the moisture content is prolix. Because sample absorbs water in the air, the cooling procedure often leads to additional errors. The new moisture balance can solve these problems. It can reduce the time of moisture measurement to 10-30 minutes from 1-4 hours.The paper consists of 6 chapters:The first chapter expounds the great significance of moisture determination, the research background and the innovation of the paper.The second chapter discusses the current situation and limitation of the present standard moisture determination methods. Then the new moisture balance based on the data fusion and prediction theory is presented.The third chapter systematically analyses the principle of the new moisture balance based on Intel 16-bit microcontroller 80C196KC, then introduces the designs of infrared oven and the MCU system The hardware schematics are also presented.The fourth chapter presents the adaptive prediction theory with shift sampling method to speed up the measuring procedure. Practical applications have testified that it is an algorithm with the characteristics of high accuracy, real-time response, stabilization and adaptation. Practical applications also show that the method is feasible.In the fifth chapter, some key techniques to quickly obtain the accurate moisture results are introduced.Finally, the deficiencies of the paper are summarized, and the methods to improve them are proposed.
