Control system capable of carrying out lifting and lowering control and displaying height value in real time

Abstract

The invention relates to a control system capable of carrying out lifting and lowering control and displaying a height value in real time. The control system is composed of a single-chip microcomputercontrol system, a stepping motor, a 24V power supply, a driver and a photoelectric encoder, wherein the 24V power supply powers the driver, the single-chip microcomputer provides control signals to the driver to drive the stepping motor. The stepping motor rotates to drives a belt wheel on the photoelectric encoder to rotate on the one hand, and drives a traction rope to tighten or release so asto realize the movement of an experimental instrument in the vertical direction on the other hand. In addition, the photoelectric encoder rotates to send out pulse signals, and after the pulse signalsare received by the single-chip microcomputer, through internal processing and conversion, real-time display of the moving distance can be carried out in a nixie tube. An operator can conveniently perform corresponding adjustment action according to the experimental requirements.

Description

technical field [0001] The invention belongs to the field of lifting platforms, in particular to a control system capable of lifting control and displaying height values ​​in real time. Background technique [0002] The transmitting and receiving coils are coaxially placed to form an experimental instrument. When a continuous step square wave signal is passed to the transmitting coil, an electromotive force will be induced in the receiving coil. With the change of the height value of the experimental instrument, the experimental environment of the instrument is changed, and the signal value received by the induction coil will also change. We want to conduct multiple sets of experimental tests by changing the height of the experimental instrument, and finally obtain the received signal value. The corresponding relationship with the height of the instrument. [0003] In order to pull and move the experimental instrument at a set distance in the axial direction, the experiment...

AI Technical Summary

Problems solved by technology

[0003] In order to pull and move the experimental instrument at a set distance in the axial direction, the experimental instrument was previously moved at equal intervals of height value manually, so that human factors have a greater impact on the accuracy of the experiment, and the distance accuracy of the equal interval movement is also lower. It is difficult to meet our requirements; and artificial movement is relatively strong for people, and the labor intensity is relatively high
