User non-perception resistance meeting control method

Abstract

The invention provides a user non-perception resistance meeting control method. A controller controls a motor to operate, and the position of a door body is detected in real time through an electroniclimiter; the operation path of the door body is divided into a plurality of position points, and the normal operation time T of the door body between the adjacent position points is measured and recorded in the descending process of the door body; when the difference value between the staying time of the door body at a certain position point and the normal operation time T is larger than time T1,the controller controls the motor to rotate reversely; when the door body rebounds and then descends to the position point, if the difference value between the staying time of the door body at the position point and the normal operation time T is larger than time T2, the controller controls the motor to rotate reversely; and when the door body rebounds and then descends to the position point, ifthe staying time of the door body at the position point reaches the maximum operation time T, the motor stops rotating reversely. When the door body is blocked, the blocking condition is preliminarilyjudged under the condition that an operator does not need to intervene.

Description

technical field [0001] The invention relates to the technical field of rolling shutter doors, in particular to a method for controlling obstacles encountered by users without perception. Background technique [0002] When some existing rolling doors encounter obstacles in the downward process, they will automatically detect and control the motor to stop or reverse. After the operator removes the obstacle or judges that there is no obstacle, he presses the down button again to control the door body to go down. In addition, due to the high height of the door body of the rolling shutter door, the door pieces in series will encounter jamming and poor operation during the movement along the guide rail, and it will also be judged as being blocked. A certain degree of deformation of the guide rail will cause this to happen. Some deformation is difficult to recover by itself, which will cause the door body to go up repeatedly and fail to work normally. The operator may manually pull...

AI Technical Summary

Problems solved by technology

In addition, due to the high height of the door body of the rolling shutter door, the door pieces in series will encounter jamming and poor operation during the movement along the guide rail, and it will also be judged as being blocked.

A certain degree of deformation of the guide rail will cause this to happen, and some deformation is difficult to recover by itself, which will cause the door body to go up repeatedly and fail to work normally. The operator may manually pull the door and apply external force to make it pass this point

That is to say, when the existing rolling door encounters obstacles in operation, it is impossible to judge whether there is an obstacle under the door body, and the operator needs to judge and perform corresponding operations
