Electromechanical transmission control system and method

Abstract

The invention discloses an electromechanical transmission control system and control method, and relates to the technical field of mechanical automatic control. According to the system, a system maincircuit firstly connects an external power supply with a main power supply circuit breaker, and a servo power supply circuit breaker controls the on-off of a high-voltage circuit; a servo control circuit controls a servo motor to move; a variable-frequency speed regulation circuit controls the rotating speed of an alternating-current motor through an analog quantity output signal of a Beckhoff controller; a Beckhoff controller circuit controls logic control of a servo driver and a frequency converter through digital signals and analog signals; and a PLC control circuit controls a proximity switch on a door to carry out safety protection and is connected with the lead wire of the system power supply circuit breaker and the proximity sensor of the servo control circuit to form a loop. According to the invention, a PLC program is written additionally, so that the motor can realize logic control and a variable-frequency speed regulation system, a man-machine interaction interface is drawn,an electrical wiring principle and a control principle of an electric control system are provided, and the practicability of the system is enhanced.

AI Technical Summary

Problems solved by technology

[0003] Practical teaching is generally solved by the following methods: one is by purchasing products from relevant experimental teaching aid manufacturers, but the manufacturers are out of touch with the school's practical teaching.

The second is to complete through the method of virtual simulation. This method generally combines simple principle experiments with virtual simulation, which fails to achieve the purpose of training students' hands-on ability and improving their overall quality.

The first PLC was large and expensive

They are only capable of on / off control, limiting their application to operations requiring repetitive movements

[0015] Through the above analysis, the existing problems and defects of the prior art are: (1) The original electric transmission experiment platform and control equipment are inconvenient to operate, and the wiring and control relationship information of the entire equipment is not easy to obtain, so it can only be accessed at the rear of the equipment. Observe, but the wiring of some electrical components in the front will be invisible, which brings a lot of trouble in actual application

[0016] (2) The function of the original electric transmission experiment platform is relatively fixed, and the operation is not flexible. If you want to add other electrical components, there will be no place to place them

Unable to independently wire and place electrical components, resulting in limited equipment practicability
