In order to speed up the sorting speed, reduce the intensity of manual labor, this project designs an automatic material sorting system based on PLC control. The system takes Siemens S7-1500 PLC as the controller, and completes the software and hardware systemdesign of six workstations in the assembly line. The system realizes the processing, assembling and sorting of cylindrical materials through feeding unit, handling unit, processing unit, handling and installation unit, installation unit, sorting unit. At the same time, the project has developed a HMI human-machine interaction system. After debugging, the system can automatically sort different color materials and achieve the expected function.

As the "mother machine" of manufacturing, machine tools have been widely employed, but with high energy consumption, low energy efficiency, and serious carbon emissions. How to reveal the dynamic characteristics of carbon emissions is of great significance for machine tools to achieve green and sustainable development. Existing research neglected the dynamic characteristics of carbon emissions and focused on a single phase for machine tool. To this end, this study carried out the digital twin-driven modeling and application of carbon emission for machine tool considering both the design and usage stages. Utilizing real-time data acquisition and model refinement of digital twin system, this research proposed an adaptive algorithm for the dynamic prediction and optimization of processing parameters. Related management services in usage stage based on digital twin was developed and a digital twin-driven carbon emission prototype system was established. And a milling experiment was performed to validate the practicality and feasibility of the proposed algorithm. Besides, combining with operation data recorded by digital twin model, working conditions of machine tool were simulated in the digital space. Optimization of tool part selection under simulated conditions can be realized during design stage, which makes the closed-loop design for machine tool. Considering both design and usage stages, this research offers a reference solution for the multidimensional, intelligent, and collaborative management of carbon emissions for machine tool.

intelligent environmental control system and smart buildings have gradually entered the public view, and users can adjust the indoor environment according to their personal preferences. However, the accuracy of control systems is susceptible to the diversity and sensitivity of user behavior. In addition, although some existing products have begun to focus on the user experience, there are still shortcomings. This paper designs a human-centric prompt interface design for winter teaching indoor space. The combination of interface design and indoor environmental control system can make accurate decisions based on user feedback. Moreover, this paper discusses the user's acceptance of this mobile panel program through questionnaires and interface usage feedback and the direction of future research.

Aiming to solve the problems of large nonlinear error, serious time lag, severe time-varying, multiple influencing parameters, and severe random interference in dissolved oxygen concentration control of sewage treatment systems, a control method based on two degrees of freedom is proposed by combining the advantages of two degrees of freedom, internal model control, and cascade PID control. This method effectively improves the problem of imprecise mathematical expressions in the aeration system and blower, which makes it difficult for other methods to achieve good control effects. The experimental results prove that the system has advantages such as outstanding adaptability, good tracking performance, significant control effect, and good robustness.
