Synthetic experiment device for monitoring system

Abstract

The invention relates to a measurement and control system comprehensive experimental device which comprises a programmable controller, a hydraulic system, a work drive motor, a loading motor, a analog-to-digital converter, a sensor, a contactor, an intermediate relay and a digital display board, wherein, the work drive motor is connected with a drive pump of the hydraulic system; the signal output terminal of the sensor arranged in the hydraulic system is connected with the input interface of the programmable controller by the analog-to-digital converter, the output interface of the programmable controller is connected with the loading motor by the intermediate relay and the contactor; and the output interface of the programmable controller is also connected with the digital display board. The invention combines experimental devices of three courses in the same set of device, thereby reducing the investment of the experimental device of single course to the utmost extent, improving the utilization rate of the device greatly and saving the cost and the space. In addition, the student does different experiments at the same experimental device repeatedly, thereby shortening the time for getting familiar with the experimental device, also taking effect of understanding the present by reviewing the past and also feeling the relation between different subjects.

Description

technical field [0001] The invention is a comprehensive experimental device of a measurement and control system, which belongs to the modification technology of the experimental device. Background technique [0002] Most of the current experimental devices are set up for the experiments of a single course, such as the three courses of "Fluid Transmission and Control", "Electromechanical Transmission Control Technology", "Principles and Applications of Programmable Controllers" set up in the engineering department of universities. For example, the experimental devices of the course "Fluid Transmission and Control" need motors, switches, buttons, pressure, flow, and speed sensors; the experimental devices of the courses "Electromechanical Transmission Control Technology" and "Programmable Controller Principles and Applications" also Motors, switches, buttons, and speed sensors are required; at the same time, experiments in the course "Electromechanical Transmission Control Tec...

AI Technical Summary

Problems solved by technology

In addition, the utilization rate of each experimental device is low, and the experimental device of each course lacks the connection between courses, and most of them stay at the verification level of scientific principles, which is out of touch with practical application, and it is difficult to arouse students' interest in learning
