Abstract

The invention discloses a remote motor control system. The remote motor control system comprises a remote unit and a motor unit, wherein the remote unit comprises a client, a server and a wireless emission module, a control instruction is inputted by the client and is sent to the server through the network, the control instruction is sent outside by the server through the wireless emission module, the motor unit comprises a wireless reception module, a PLC, an intermediate relay, a contactor, a frequency converter and a motor, the wireless reception module is used for receiving the control instruction from the wireless emission module and sending the control instruction to the PLC, the intermediate relay, the contactor and the frequency converter are sequentially connected between the PLC and the motor, the motor is controlled by the frequency converter for rotation, a rotating speed signal of the motor is detected through a photoelectric encoder and is fed back to the PLC, and an closed loop control system is formed. The remote motor control system is advantaged in that data transmission is carried out through the wireless network, real-time control on the PLC is carried out, flexible control on the rotation speed of the motor is realized through the frequency converter, and the remote control purpose is realized.

Description

technical field [0001] The present application relates to the control of motor speed regulation, in particular to a motor remote control system. Background technique [0002] Frequency conversion speed regulation can improve the efficiency of large-scale equipment such as hoists and fans, and realize effective control of motors. This has also become one of the most promising and ideal speed regulation methods. [0003] At present, in the industrial automation control system, the combination of PLC and frequency converter is adopted, the control is simpler, the work is faster, the measurement is more accurate, and it has strong anti-interference ability. [0004] Traditional motor control requires on-site control, which has low work efficiency and high cost. Contents of the invention [0005] The purpose of the present invention is to provide a motor remote control system to overcome the deficiencies in the prior art. [0006] To achieve the above object, the present inve...
