Description

technical field [0001] The invention relates to the technical field of teaching instruments, in particular to a single-loop rapid temperature control experimental teaching device for teaching. Background technique [0002] Temperature is one of the ubiquitous and important physical parameters in production processes and scientific experiments. In many production processes, temperature measurement and control are not only closely related to major technical and economic indicators such as production safety, production efficiency, product quality, and energy conservation, but also an important task to realize the automation of industrial production processes. [0003] Temperature measurement is the basis of temperature control, and the measurement technology is relatively mature. As the controlled object becomes more and more complex, there is a need to better improve the control performance to meet the control requirements of different systems. At present, there are many meth...

Problems solved by technology

[0004] With the development and demand of industrial production automation, general colleges and vocational colleges have also opened related majors and courses, but at present, the teaching of process control courses in most schools is still at the stage of book teaching, while experimental instruments are relatively Lack of resources can not meet the needs of teaching experiments for process control majors in colleges and universities. If water temperature measurement is used in the experiment, the temperature rises slowly, which involves water intake and waterproof problems before and after the experiment. It is also easy to cause potential safety hazards if it is connected to the power supply. Therefore, it is necessary to design and provide a device that meets the teaching experiments of process control to meet the requirements of classroom teaching experiments and enhance students' awareness of course content and industrial production process automation. It can also provide physical simulation objects and experimental means related to industrial process automation for graduate students and researchers in the research of complex systems and advanced control systems
