Roller blind device control method

Abstract

The invention relates to the field of electric roller blinds, in particular to a roller blind device control method, which includes steps: the controller analyzes received orders; if the orders are fabric rolling orders, the controller enables a cord pulling motor to release a brake and be added with damp voltage; a fabric pulling motor is enabled to release a brake and starts to rolling fabric; when stopping orders are received, the controller enables the cord pulling motor to start the brake and remove the damp voltage; the fabric pulling motor is enabled to continue operating for a period of time T1 and then stops to start the brake; if cord rolling orders are received, the controller enables the fabric pulling motor to release the brake and be added with damp voltage; the cord pulling motor releases the brake and starts to rolling cords; when stopping orders are received, the controller enables the fabric pulling motor to start the brake and remove the damp voltage; and the cord pulling motor continues operating for a period of time T2, and the cord pulling motor stops to start the brake. Using the roller blind device control method can achieve preconceived tensioning effect more easily.

Description

technical field [0001] The invention relates to the field of electric roller blinds, and more specifically, relates to a method for controlling a roller blind device. Background technique [0002] With the development of technology, large-area roller blinds, such as ceiling blinds, have realized motorized control. Taking the existing ceiling blind roller blind device as an example, such devices generally include winding ropes, fabrics, pull rope motors, pull Cloth motor and controller, the controller controls the rope motor and the cloth pulling motor to work synchronously. In order to ensure the dynamic stability of the fabric movement and prevent the ceiling curtain from sagging, the fabric tension system is specially designed. One of the rope motor and the cloth pulling motor When the motor is working, the controller will make the other motor release the brake, and apply a damping voltage to make the motor generate a certain damping force, so that the fabric is always in ...

AI Technical Summary

Problems solved by technology

The control method of the roller blind device in the prior art is to stop the rope motor and the cloth pulling motor at the same time, so that the tension force of the fabric is basically the same as the damping force of the corresponding motor, which may not meet the requirements of the final tension force, especially Roller blinds with long fabrics tend to sag obviously. If the damping force of the motor is simply increased, it will have a better effect under certain circumstances, but it puts forward higher requirements for the corresponding working motor, which needs to have greater Traction, when the original motor can not provide, it is necessary to choose a motor with a larger torque, which increases the cost
