There are two ways to position fast rolling shutters
Mechanical positioning This positioning method is similar to that of steel rolling shutters. The advantage is that it is fast and has low requirements on the controller.
Rotary encoder positioning The elevators we often take are all positioned using rotary encoders. The advantage of this method is accurate positioning. Taking an encoder with a resolution of as an example, a meter-high door is divided into nearly , in theory, the accuracy can be as high as height setting. For example, the fast rolling door control system designed by Shaoxing Anyi only has one button to set the height. This is very practical. If you only pass people, setting the height to meters is enough, which avoids Opening it is in vain. If a tall object such as a forklift passes by, just reset the height. The disadvantage is that the rotary encoder itself is relatively expensive, is a delicate component, and needs to be used in conjunction with the program, so the cost of the control system is relatively high.
