Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent motor control equipment, and in particular relates to an intelligent motor speed regulation and control system. Background Technology

[0002] In actual production, traditional motor speed control circuits require external control signals or frequency control signals provided by potentiometers on-site. This is inconvenient and imprecise. In contrast, intelligent motor speed control systems allow for motor speed control from the back-end system and on-site adjustment of motor control, which is beneficial for industrial automation. Different solutions can be adjusted in different ways, and the system is also safer. Utility Model Content

[0003] The purpose of this invention is to improve upon the shortcomings of existing technologies by providing an intelligent motor speed control system that features a simple production process, high reliability, excellent control effect, and long-term safe and reliable operation.

[0004] The purpose of this utility model is achieved as follows: an intelligent motor speed control system, characterized by including a power module, a handheld controller, a frequency converter, a motor, and a backend system, wherein:

[0005] The power module is used to provide AC220V power to the handheld device;

[0006] The handheld device is used to display the real-time status, and at the same time converts the control signals into electrical signals and transmits them to the frequency converter. The handheld device is equipped with an RS485 communication interface, through which the control status is transmitted to the external background system.

[0007] The frequency converter is used to receive control electrical signals transmitted by the handheld device, adjust the frequency, and realize speed control of the motor.

[0008] The aforementioned back-end system is used to set the frequency of the frequency converter and realize motor speed control when the staff is not on site.

[0009] Compared with existing technologies, this utility model has the following significant features and positive effects: When the operator is on-site, the target value needs to be set through a handheld device. Its internal components convert the target value into a corresponding electrical signal, process the signal, and then transmit the control status signal to the frequency converter via a signal line. Simultaneously, the real-time status is fed back to the back-end system via a communication signal. The frequency converter achieves frequency setting through internal conversion, thereby realizing motor speed control. When not on-site, the frequency of the frequency converter can be set through the back-end system to achieve motor speed control. The handheld device and the frequency converter are connected by a signal line, ensuring safe use and reducing accidents. It is lightweight, aesthetically pleasing, and simple, enabling motor speed control both on-site and off-site. This utility model achieves intelligent control of motor speed, has strong compatibility, and can feed back status signals to the upper-level control system, ensuring safe use and reducing accidents.
