Pull and stop electric curtain control system and method

Abstract

The invention discloses a pull and stop electric curtain control system and method. The method comprises the following steps: acquiring control information, controlling a curtain to perform corresponding running, wherein the control information comprises an open instruction and a close instruction; when the curtain begins running, initializing the current maximum load current of a motor, and acquiring instantaneous load current of the motor at the interval of threshold time; and setting the alpha times of instantaneous load current as the current maximum load current of the motor; judging whether the instantaneous load current of the motor at the next moment is greater than the current maximum load current of the motor; if the instantaneous load current of the motor at the next moment is greater than the current maximum load current of the motor, controlling the motor to stop running. Through the control system disclosed by the invention, the motor can be automatically stopped by usingsmall tensile force by the children or the old and like population with weak action capability, thereby preventing the problems that the curtain is prone to be broken due to the tensile force, the belt of the curtain is easy to collapse and the motor fault rate is high to a certain degree.

Description

technical field [0001] The invention relates to the field of curtain control, in particular to an electric curtain control system and method that can be pulled and stopped at any time. Background technique [0002] Electric curtains in today's market can only be stopped when they encounter greater resistance, so that they can be dealt with when facing normal customer groups. However, if you are facing groups with weak mobility such as children or the elderly, the electric curtains on the market today are difficult to meet their needs, and when in use, if the curtains can only be stopped when encountering a large resistance, the curtains will be in the air. During use, the problems that the curtains are easily pulled, the belts of the curtains are easily broken, and the failure rate of the motor are relatively high. [0003] Therefore, today's market is badly in need of an electric curtain control system and method that can be pulled and stopped at any time, which can automa...

Problems solved by technology

However, if you are facing groups with weak mobility such as children or the elderly, the electric curtains on the market today are difficult to meet their needs, and when in use, if the curtains can only be stopped when encountering a large resistance, the curtains will be in the air. When using, the curtains are easy to be pulled, the belts of the curtains are easy to break, and the failure rate of the motor is high.

[0003] Therefore, today's market is badly in need of an electric curtain control system and method that can be pulled and stopped at any time, which can automatically stop the motor with a small pulling force for groups with weaker mobility such as children or the elderly. Groups with weak mobility can play a certain protective role, and truly "stop at any time" can also prevent the curtains from being easily pulled, the curtain belts from breaking, and the motor failure rate to a certain extent.
