Electric rotary table control system and control method thereof

Abstract

The invention discloses an electric rotary table control system which comprises first proximity switches, second proximity switches, a master controller and a stepping motor control chip used for controlling operation of a stepping motor, wherein the first proximity switches, the second proximity switches and the stepping motor control chip are all connected with a main control signal; sensing positions are arranged in the circumferential direction of the rotary table at intervals, the sensing positions comprise triggering positions and non-triggering positions, and the triggering positions and the non-triggering positions are alternately arranged at equal intervals; and the first proximity switches and the second proximity switches are sequentially arranged in the clockwise rotation direction of the rotary table, and one sensing position is arranged between the first proximity switch and the second proximity switch. The electric rotary table control system mainly solves a series of problems existing in the motor control technology of the electric rotary table. Through the cooperation of a sensor, triggering positioning and the non-triggering positions, the starting, stopping, forward and reverse rotation, acceleration and deceleration functions of the electric rotary table can be realized, the functions are complete, no external control mechanism such as a remote controller and a hardware switch is needed, and cleaning is facilitated.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to an electric turntable control system and a control method thereof. Background technique [0002] At present, many high-end dining tables use electric turntables. Commonly used electric turntables include turntables and motors. The turntables are driven by motors. There are three main motor control methods for electric turntables: [0003] 1. Adopt hardware switch control: close the switch to power on the motor, the turntable will rotate, turn off the switch to power off the motor, and the turntable will stop rotating; [0004] 2. Sensor control: use infrared sensors or capacitive sensors to detect the state of the turntable; when the motor stops, the personnel will move the turntable to make the sensor send a signal, and the main control will control the motor to start rotating; when the motor is running, the personnel will press the turntable, Make the sensor ...

AI Technical Summary

Problems solved by technology

[0006] The above three motor control methods all have their disadvantages: when using hardware switch control, it is necessary to install a switch on the dining table, which affects the appearance of the dining table, is not conducive to cleaning, and the function is relatively single; when using sensor control, the function is still relatively single; using a remote control When controlling, the remote control needs to replace the battery from time to time, and the remote control is easy to lose
