Problems solved by technology

[0005] 1) Use a linear drive circuit to drive the motor, which has low efficiency and serious heat generation
[0006] 2) The design of the experimental box makes the equipment bulky and difficult to maintain
[0007] 3) Use data acquisition card for data acquisition, the connection is complicated and error-prone
[0010] 1) It does not have the function of building an analog circuit experiment
[0011] 2) Different experiments need to re-program the DSP, which is inconvenient

Abstract

The invention discloses an intelligent component-based automatic control integrated teaching experiment platform comprising an intelligent driving component, a signal acquisition component and a simulator component. A PWM wave driving DC motor is used as the intelligent driving component which has three modes of a photoelectric encoder, a speed measuring motor and a photoelectric switch to acquirethe rotating speed and the angle of the motor. The signal acquisition component is used for acquiring or outputting analog, digital or frequency signals. The simulator component comprises multiple independent operational amplifiers and the peripheral resistors and capacitors thereof so as to establish various analog circuits. All the components can be independently used or combined so that motorcontrol and analog circuit control of the automatic control teaching experiment can be realized; besides, the intelligent driving component and the signal acquisition component can communicate with the PC through the ethernet so as to form upper and lower computer experiment systems. The teaching experiment platform has the characteristics of flexible combination, diverse functions, small size andconvenient maintenance.

Description

technical field [0001] The invention relates to an intelligent component type automatic control comprehensive teaching experiment platform, which belongs to the field of teaching experiment equipment and is used for the teaching experiment of automatic control courses. Background technique [0002] In the teaching practice of automatic control courses, open-loop control, closed-loop control, speed feedback correction, object characteristic recognition, digital control and other experimental contents are usually arranged. If only analog computer or digital computer is used for simulation experiment, it cannot be well combined with engineering practice, and the teaching effect is not obvious. The invention designs an intelligent component type automatic control experiment teaching platform, which can effectively help students understand the principle of automatic control. [0003] Zhang Tianhong designed a teaching experiment system for automatic control courses centered on t...
