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

Abstract

The invention discloses a single-circuit fast temperature-control experiment teaching device, which comprises a controlled object, a sensor, a temperature transmitter, an intelligent regulation instrument, a pressure regulating module and an upper computer, wherein a heat source adopts a halogen tungsten lamp, and can realize rapid warming and cooling; the intelligent regulation instrument is connected with the upper computer through an RS232 communication port so as to realize output of controlled quantity; the upper computer is provided with a configuration software; and through adjusting PID (Proportion Integration Differentiation) parameters, a system can have good dynamic property indexes, and real-time and historical data and curves of the system can be recorded. The single-circuit fast temperature-control experiment teaching device well simulates an automatic operation and management platform in an industrial process, not only can meet the requirement of an undergraduate student on a process control experiment, but also provides an experiment platform for intensive study of graduate students, has a simple and reasonable structure, is convenient to operate and maintain, and can be widely applied to student experiments.

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...
