Experiment equipment for starting and stopping of motor

Abstract

The invention discloses an experiment equipment for starting and stopping of motor, comprises a processor, a power supply, at least one solid state relay module, a memory module and a display module.The solid state relay module comprises a solid state relay drive interface circuit and a solid state relay, a control end of the solid state relay drive interface circuit is connected to an output port of the processor, the output end of the solid state relay drive interface circuit is connected to the solid state relay, the solid state relay is connected to the start stop control loop of the motor; the data access control port of the memory module is connected to a serial data port of the processor, the memory module is suitable for storing data in powering down; a data input end of the display module is connected to the output port of the processor, the processor is suitable for setting the start time and the stop time of the motor, saving the start time and the stop time in the memory module, and sending to the display module for display; and the motor is started and stopped periodically according to the starting time and the stopping time. The experiment equipment for starting andstopping of motor prolongs the service life of the traditional mechanical time relay, and enhances the electrical isolation.

Description

technical field [0001] The invention relates to an experimental equipment for starting and stopping a motor. Background technique [0002] The traditional time relay belongs to the mechanical contact switch switching control method. If it controls large current and high voltage, it is easy to generate sparks, which will affect safety, cause large EMI interference, and the contact switching life is short. The number of switching times is about 100,000 times, and the average current passing Small, only 1-5A, and the on and off time cannot be specifically set and displayed, the cycle period of the on and off times cannot be recorded and queried, and the power failure cannot be saved, etc., the scope of use is narrow, the use is not flexible, and it is not humanized enough to realize The control function is single. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems indicated in the background art. [0004] In order to a...
