Abstract
In the production process of nuclear fuel elements, a large amount of uranium-containing alkali residue will be produced. In order to solve the problems of low efficiency and long time, a PLC-based alkali residue pretreatment device platform is proposed. Through the overall scheme design of the platform, the work flow is determined, and the communication between the upper computer and the alkali residue pretreatment device, the communication between the upper computer and the PLC are mainly solved. In terms of system hardware, the design and selection of electrical control principle, the selection of PLC model, the design of vacuum pipeline and the design of wiring diagram are carried out. In terms of control system software, STEP 7-Microwin SMART is used to write the control program of PLC as the main controller, and then the human-computer interaction interface is designed by Visual Studio2015, and the measured data is put into the database by connecting with the SQL2012 database. Finally, the human-computer interaction is realized by PC compilation, and the experimental platform is started and debugged. The final experimental results show that the whole platform meets the requirements of industrial production.
