「保定快速门」堆积门机械限位与编码器限位方式对比

 

Comparisons of Mechanical Limitation and Encoder Limitation of "Baoding Fast Gate" Stacking Gate

 

快速门一般运用在电子厂、无尘车间、清洁室等对环境要求非要高的地方，不过对于大部分人来说并不了解快速门，今天先给大家普及一下快速门的一些小知识。快速门主要有哪些定为方式呢。


Fast doors are generally used in electronic factories, dust-free workshops, cleaning rooms and other places where environmental requirements are not high, but for most people do not know fast doors, today we first give you some knowledge of fast doors. What are the main ways of fast door design?

 

「保定快速门」堆积门机械限位与编码器限位方式对比



Comparisons of Mechanical Limitation and Encoder Limitation of "Baoding Fast Gate" Stacking Gate


机械定位：


Mechanical positioning:


这种定位方式和钢制卷闸门的差不多，优点是速度快，对控制器要求低。


The positioning method is similar to that of steel coil gate, which has the advantages of fast speed and low requirement for controller.


旋转编码器定位：


Rotary encoder positioning:

我们常乘的升降电梯都是用旋转编码器定位的，这种方式的好处是定位准，以分辨率为1024的编码器为例，3米高的门分成将近9000个点，理论上精确度可以达到0.3mm,高度设定简略，有的计划的快速卷帘门控制系统只有一个按键便可以任意设置高度，这个很实用，如果只过人，高度设到2米就足够了，避免徒劳的敞开，如有叉车等高大的物体通过，则重设一下高度就可以了。


he elevator we often take is positioned by rotary encoder. The advantage of this method is positioning accurately. Take the encoder with 1024 resolution as an example, the 3-meter-high door is divided into nearly 9000 points. In theory, the accuracy can reach 0.3 mm, the height setting is simple, and some planned fast shutter door control system has only one button to facilitate. The height can be set arbitrarily. This is very practical. If the height is only over 2 meters, it is enough to avoid futile opening. If a forklift truck and other tall objects pass through, it is enough to reset the height.


缺点是旋转编码器本身价格较高，属精密部件比较娇贵，而且需要和PLC程序配合应用，以是控制系统造价偏高。


The disadvantage is that the rotary encoder itself is expensive, and it belongs to precise parts, and needs to cooperate with the PLC program, so the cost of the control system is high.
