Mechanical positioning 1 industrial door: the location and the steel gate is similar, the advantages are speed, low requirement on the controller.
2 rotary encoder positioning: we often take the elevators are rotating encoder for positioning, the benefit of this approach is accurate positioning, with a resolution of 1024 of encoder as an example, 3 meters tall doors into nearly 9000 points, theoretical accuracy can be achieved 0.3mm, height setting simple.
一般设计的工业门
Industrial door control system design has only one button can be set arbitrarily high, this is very practical, if only people, height to 2 meters is enough, to avoid futile open, such as forklifts and other tall objects through, according to the signal input different change the opening height. Disadvantage is the higher prices of rotary encoder itself, precision parts more delicate, and need and PLC procedures with the use, so the control system of the high cost of rapid door.
