Control method and control device for electric rolling screen type window shutter

Abstract

The invention discloses a control method and a control device of an electric rolling shutter; a driving motor transmission connected with the winding shutter is arranged; a switch control circuit is used for controlling the open and close of the corotation and reversion of the driving motor; a controller with data-processing function is used for controlling the work of the switch control circuit;the data of an upper terminal position, a lower terminal position of the shutter and at least one specified middle position is stored in a memory; a sensor is arranged, which is used for measuring the real-time lifting position data of the moving shutter during the rising and declining process of the shutter, and the data is input into a comparator to be compared with the data value which is selected as the comparative object by the controller in the memory; when the compared result is equal, the controller switches off the driving motor by the switch control circuit, so that the shutter automatically stops at the selected position. Only by simple operation, the rolling shutter can automatically and accurately stop at the specified terminal or middle position, thus being convenient for use.

Description

technical field [0001] The invention belongs to an electronic control method and device, in particular to an electronic control method and device for controlling the lifting of shutters. Background technique [0002] Electric-driven roller blinds are manually operated by the user to press the button switch to control the drive motor to drive the blinds down or roll up. One of the basic functions of the existing blinds is that people continue to press an up button or down. Press the button, and the roller shutter will continue to rise or fall, and when it reaches the upper terminal or the lower terminal, the sensor provided at the upper terminal and the lower terminal will send a signal to automatically disconnect the driving motor. If people want to make the blinds stop at an intermediate position, they need to control the time of holding the button and releasing the button so that the roller blind stops at this position. , so that it is necessary to observe with the naked ...

AI Technical Summary

Problems solved by technology

If people want to make the blinds stop at an intermediate position, they need to control the time of holding the button and releasing the button so that the roller blind stops at this position. , so that it is necessary to observe with the naked eye and repeatedly press the button to perform the lifting correction, which is very inconvenient. Adjustment, and the reflection of the glass window will also affect the adjustment of the user, which will bring great inconvenience to the user
