The invention relates to a fieldbus control system of jet flow drying equipment. The fieldbus control system of the jet flow drying equipment comprises radio frequency drying work equipment. The fieldbus control system is characterized in that the fieldbus control system further comprises a main controller, a fieldbus and function modules, wherein the function modules are connected with the fieldbus, and the fieldbus is in communication connection with the main controller through a bus protocol communication module. According to the fieldbus control system of the invention, advanced fieldbus technology and distributed-type input and output modules are adopted, system components and external control wiring are significantly reduced, and the design of the equipment and a control device can be simplified, and the workload and error rate of production and manufacturing as well as installation and debugging can be decreased, and therefore, the production, debugging and maintenance cost of the equipment can be decreased. With the fieldbus control system of the jet flow drying equipment adopted, a universal platform can be provided for wide use of standard fieldbuses, and strong technical support can be provided for the development of generalization and standardization of the jet flow drying equipment. The fieldbus control system of the jet flow drying equipment of the invention is advantageous in progressiveness in technology and a broad market prospect.
Description
technical field [0001] The invention relates to a field bus control system of jet flow drying equipment. Background technique [0002] Jet drying is supersonic airflow crushing and drying technology. According to the theory of aerodynamics, a supersonic airflow is generated through a venturi tube and an airflow generator. The material is crushed and dehumidified through the venturi tube, and the water and dry material are separated by a high-speed centrifugal fan. At the same time, the jet drying equipment can be enlarged through multiple sets of series and parallel connections. Parallel connection can increase the processing capacity, and series connection can not only improve the dryness of materials, but also realize particle size classification of materials. [0003] At present, no matter what kind of controller (such as PLC, single-chip microcomputer, industrial computer, etc.) is used for the control device of jet drying equipment, the connection of its control points ...
