Integrated controller for spray drying instrument

The invention relates to an integrated controller for a spray drying instrument, in particular to an integrated controller for a spray drying instrument developed based on ARM7 and including multiple kinds of domain knowledge like multi-module combination, integrated control method, automatic control algorithm, computer communication and intellectualized design. The controller is used for completing integrated control for the modules through a control core of an ARM system based on an ARM embedded development technology; an embedded control module is used for completing data processing of other modules, and an air speed detection control module is used for completing the control for required cold air speed of the spray drying instrument. The integrated controller is used for combing the automatic control algorithm, a computer technology, a network communication technology and the like together, a modularized idea is adopted, through centralized control, the collection and control for important data of product are realized, intellectualized automatic control is realized, and the integrated controller has good practical value; moreover, the integrated controller is novel in design idea, simple in operation and better in expansibility, so that the control for the spray drying instrument is more intelligent and convenient.
