Problems solved by technology

However, in some occasions, the resistance may need to reach a large value before the motor can detect it, which will cause danger to people or objects under the roller blind, and even damage the roller blind and the motor; and in some occasions, the resistance may If it only reaches a small value, for example, due to the influence of factors such as climate or dust accumulation or uneven friction, the motor will detect it, even during normal operation, it will be misjudged as encountering resistance, affecting normal use

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A method for eliminating differences in motor mechanical manufacturing and load differences during installation and use. Firstly, install the driving motor on the roller blind, and power on after the installation is completed.

[0025] see figure 1 , the method of the present invention comprises the steps:

[0026] Step S1: The motor or the remote controller is provided with a sample learning key or a combination key. The operation of the remote control can be used to control the operation of the motor. By pressing the sample learning key or the combination key, the motor can enter the sample learning mode; or, the motor Automatically enter the sample learning mode after power-on;

[0027] Step S2: A microcontroller is installed in the motor. When the microcontroller detects that the motor has entered the sample learning mode, it cont...

Abstract

The invention discloses a method for eliminating motor machinery manufacturing difference and load difference in installation and application. The method comprises the following steps that: a motor enters into a sample learning mode after being installed and electrified; operation data detected in the learning mode is amended and compensated; and all interference data is filtered out, and then characteristic values, namely change characteristics of pulse width, cycle, phase, amplitude and the like of the operation data, are extracted. The sample data obtained by using the method serves as references for resistance encountering judgment or stroke control when the motor normally operates, so as to judge the operation state of the motor, thus the probability of false detection is reduced, and the operation reliability of the motor is improved.

Description

technical field [0001] The invention relates to a method for eliminating mechanical manufacturing differences of motors and load differences during installation and use. Background technique [0002] At present, electric roller blinds driven by motors have replaced manual roller blinds, and are widely used in venues, hotels, garages and other places. However, the general motor has been set with a fixed program before leaving the factory. When it needs to be used in different environments, due to the inconsistency of the mechanical manufacturing process and the difference in the load of the driven roller blind, there will be accidents during the operation. disorder phenomenon. [0003] Taking the roller blind with the function of detecting obstacles as an example, when an obstacle is encountered, the roller blind can be stopped or even bounced up to ensure the safety of people or objects. However, in some occasions, the resistance may need to reach a large value before the ...
