伸缩门是现代建筑中必不可少的设备，因此如何打开和关闭滑动式电动伸缩门？
Expansion doors are essential equipment in modern architecture, so how to open and close sliding electric expansion doors?
平移电动伸缩门接收部分的滤波波形，因为带有载波的超声波发射后，反射回波将以直线返回。根据S＝VT/2，可以计算从发射端口和接收端口到反射表面的距离。主控制MCU使用此原理计算开关阈值极限和红外极限之间的距离。
The filtering waveform of the receiving part of the translational electric telescopic door is because after the ultrasonic wave with a carrier wave is transmitted, the reflected echo will return in a straight line. According to S=VT/2, the distance from the transmitting and receiving ports to the reflecting surface can be calculated. The main control MCU uses this principle to calculate the distance between the switch threshold limit and the infrared limit.
因为超声波由于温度变化和波速的变化特征,为门控制系统,利用该地区跨度非常大,北到哈尔滨,南至海南,他们有可能会造成温差大门限制问题。打开门在这个时间限制初始化关键约2秒钟,然后打开门限制初始化将明亮的灯光,当门限制初始化将熄灭灯光,门后表示限制初始化已经完成。
Due to the characteristics of temperature and wave velocity changes, ultrasound is a door control system that utilizes a very large span in the region, from Harbin in the north to Hainan in the south. They may cause temperature difference gate restrictions. Opening the door at this time limit initializes the key for about 2 seconds, and then opening the door limits initializes the bright light. When the door limits initializes, the light will turn off, and after the door, it indicates that the limit initialization has been completed.
温度系数为负的热敏电阻用于AD采样，平移电动伸缩门通过查找表计算出当时的温度。根据测量的温度，对超声波传输速度进行校正，从而测量准确的开关阈值极限，以及红外极限之间的距离。参考开关阈值限值的距离由输入自动测量或系统初始化，然后存储在EEPROM中。
A thermistor with a negative temperature coefficient is used for AD sampling, and the translation electric telescopic door calculates the current temperature through a lookup table. Based on the measured temperature, the ultrasonic transmission speed is corrected to measure the accurate switch threshold limit and the distance between the infrared limits. The distance of the reference switch threshold limit is automatically measured by the input or initialized by the system, and then stored in EEPROM.
系统初始化方法如下:开门限制,系统已经成功地将开门的距离限制系统中的数据保存区,关闭限制初始化是一个打开的大门关闭间距,此时关闭按住限制初始化键2秒州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定空压机 高碑店养老院,然后平移电动伸缩门关闭限制初始化将明亮的灯光,当关闭限制初始化熄灯后表示关闭限制初始化已经完成,红外限制初始化工作也按照样本,当初始化完成后,门可以正常行走。
The system initialization method is as follows: door opening limit. The system has successfully limited the distance of the door opening to the data storage area in the system. The closing limit initialization is an open door closing interval. At this time, press and hold the limit initialization key for 2 seconds, and then translate the electric telescopic door closing limit initialization to bright light. When the closing limit initialization is turned off, it indicates that the closing limit initialization has been completed. The infrared limit initialization work is also carried out according to the sample, After initialization is completed, the door can walk normally.
