Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] refer to figure 1 , figure 1 It is a schematic structural diagram of a load imbalance detection device for a hardware operating environment involved in the solution of the embodiment of the present invention.

[0040] Such as figure 1 As shown, the load unbalance detection device may include: a processor 1001 , such as a CPU, a load 1002 , a user interface 1003 , a variable frequency motor 1004 and a memory 1005 . Wherein, the load 1002 is the object controlled by the variable frequency motor. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The memory 1005 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a dis...

Abstract

The invention discloses a load unbalance testing method, a device and a computer readable storage medium. According to the invention, the torque of the load is tested when the load is in an accelerated rotation process so that the minimal value of the current torque of the load rotating for a round could be obtained; based on the minimal value of the current torque and the previous baseline value, the current baseline value is determined. The different between the minimal value of the current torque and the current baseline value is calculated; and based on the difference, whether the load is in an unbalanced state or not can be determined, therefore, realizing the unbalance testing in a dynamic stage and avoiding the damage to the device caused by the collision of the mechanical parts of the device. In addition, the testing cost and the testing difficulty are both low.

Description

technical field [0001] The present invention relates to the technical field of load detection and control, in particular to a load imbalance detection method, device and computer-readable storage medium. Background technique [0002] When the load driven by the variable frequency motor is unbalanced, the higher the speed of the variable frequency motor, the greater the vibration and noise of the load, thereby reducing the service life of the equipment. [0003] In order to reduce vibration and noise, the variable frequency motor needs to detect the unbalance of the load (for example: drum) immediately, so as to adjust the speed or change the unbalanced state of the load. The following two unbalanced detection methods are provided in the prior art: [0004] (1) A sensor is used to detect whether the load is balanced, but the cost of the sensor is high and it is not easy to install, which makes the detection difficult. [0005] (2) In the stable low-speed operation stage (tha...
