A teaching experiment platform for automatic process control

Abstract

The invention discloses an automatic process control teaching experiment table which comprises an operating table. The operating table is provided with a display instrument part, an electrical control part, an execution and collection control part, a medium container and a human-computer interaction interface part. The display instrument part comprises a flow display instrument, a pressure display instrument, a temperature display instrument and a liquid level display instrument. The execution and collection control part comprises a solenoid valve, an electric adjusting valve, a magnetic pump, a turbine flow transmitter, a pressure transmitter, a temperature transmitter and an ultrasonic liquid level transmitter. The electrical control part comprises a frequency converter and a PLC. The medium container comprises a container body A, a container body B and a container body C, and the container body B and the container body C are arranged above the container body A. By means of the simple and visual human-computer interaction interface, students can operate the table more conveniently, and meanwhile the control process and effect can be displayed visually. The automatic process control teaching experiment table has the advantages of being simple in structure, convenient to operate, low in manufacturing price and the like.

Description

technical field [0001] The invention relates to the field of automatic instruments and meters, in particular to a teaching experiment platform for automatic process control. Background technique [0002] Industrial automation is the control of various parameters in industrial production to achieve various process controls. In industrial production, human operations are minimized, and energy and various information other than animals are fully utilized to carry out production work. Industrial automation technology is a kind of use of control theory, instrumentation, computer and other information technology to realize detection, control, optimization, scheduling, management and decision-making of industrial production process, so as to increase production, improve quality, reduce consumption and ensure safety. Comprehensive high technology. [0003] At present, the number of automated training platforms in colleges and universities is limited, and the applicable programs for...

AI Technical Summary

Problems solved by technology

[0003] At present, the number of automated training platforms in colleges and universities is limited, and the applicable programs for each training platform are fixed, and the scalability is poor. It is convenient for students to operate manually, and it is difficult to carry out verification training of automatic control. It is difficult for students to apply the theory obtained from theoretical books to actual equipment operation, which affects students' understanding and consolidation of book knowledge.
