Embodiment Construction

[0032] The remote control system in the present invention can realize the remote control function through the frequency converter, effectively saving costs.

[0033] see figure 1 , an embodiment of a remote control system in the present invention, comprising:

[0034] System host 1, information transceiver device 2, frequency converter 3 and motor 4;

[0035] The system host 1 sends control commands to the information transceiver device 2 and receives feedback information;

[0036] The information transceiving device 2 receives the control command sent by the system host 1, converts the control command into a control curve that can be recognized by the frequency converter 3, and sends the control curve to the frequency converter 3;

[0037] The frequency converter 3 receives the control curve, and controls the characteristic parameters of the motor 4 according to the control curve.

[0038] It should be noted that the system host 1 is capable of controlling a plurality of c...

Abstract

The embodiment of the invention discloses a remote control system. The remote control system can achieve the remote control function through a frequency converter, and cost is effectively saved. The remote control system comprises a system host 1, an information receiving and transmitting device 2, the frequency converter 3, an electromotor 4 and an encoder 5. The system host 1 transmits a control command to the information receiving and transmitting device 2, the information receiving and transmitting device 2 receives the control command transmitted by the system host 1, the control command is converted into a control curve capable of being recognized by the frequency converter 3, and the control curve is transmitted to the frequency converter 3. The frequency converter 3 receives the control curve, and characteristic parameters of the electromotor 4 are controlled according to the control curve. The operating state of the system is fed back to the system host 1 to be analyzed in real time through the information receiving and transmitting device, and the judgment is made.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to a remote control system. Background technique [0002] With the rapid development of modern science and technology, the prospect of using frequency conversion technology for power equipment is becoming more and more broad, and electric motors using electricity as energy are becoming more and more popular. In order to effectively control the power of the motor under the condition of energy saving, the frequency converter is used to drive it. The frequency converter can change the frequency, voltage and other parameters of the input motor to control the number of revolutions and torque. [0003] Therefore, the frequency converter must be equipped with a corresponding control system to drive the power through the control of the frequency converter. In order to achieve reliable application and ensure the safe, energy-saving and effective operation of the power, the design a...
