User-insensitive blocking control method

Abstract

The present invention provides a user-insensitive control method for encountering obstacles. The motor is controlled by a controller, and the position of the door is detected in real time by an electronic limiter; And record the normal operation time t of the door body between adjacent position points, when the difference between the residence time of the door body at a certain position point and the normal operation time t is greater than time t1, the controller controls the The motor reverses; when the door rebounds and goes down to the position point, if the difference between the time the door stays at the position point and the normal operating time t is greater than time t2, the controller Control the reverse rotation of the motor; when the door rebounds and goes down to the position point, if the door stays at the position point for a maximum running time T, the motor reverses and stops. When the door body is blocked, the preliminary determination of the blocked situation can be realized without operator intervention.

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
