电动门的基本原理
电动门的基本原理
Basic principle of electric door
电动门的系统配置是指根据使用要求而配备的，与电动门控制器相连的外围辅助控制装置，如开门信号源、门禁系统、安全装置、集中控制等。必须根据建筑物的使用特点。通过人员的组成，楼宇自控的系统要求等合理配备辅助控制装置。
The system configuration of electric door refers to the peripheral auxiliary control devices connected to the electric door controller, such as door opening signal source, access control system, safety device, centralized control, etc., which are equipped according to the use requirements. It must be based on the use characteristics of the building. Auxiliary control devices shall be reasonably equipped according to the composition of personnel and the requirements of building automation system.
1、开门信号
1. Door opening signal
电动门的开门信号是触点信号，微波雷达和红外传感器是常用的两种信号源：微波雷达是对物体的位移反应，因而反应速度快，适用于行走速度正常的人员通过的场所，它的特点是一旦在门附近的人员不想出门而静止不动后，雷达便不再反应，电动门就会关闭，对门机有一定的保护作用；红外传感器对物体存在进行反应，不管人员移动与否，只要处于传感器的扫描范围内，它都会反应即传出触点信号。缺点是红外传感器的反应速度较慢，适用于有行动迟缓的人员出入的场所。另外，如果电动门接受触点信号时间过长，控制器会认为信号输入系统出现障碍。而且自动平移门如果保持开启时间过长，也会对电气部件产生损害。由于微波雷达和红外传感器并不了解接近u型槽模具 井盖钢模具 保定雅思 一次性止血带 保定养老院 保定水处理设备 一次性止血带 电动门的人是否真要进门，所以有些场合更愿意使用按键开关。
The opening signal of the electric door is a contact signal, and microwave radar and infrared sensor are two commonly used signal sources: microwave radar is a displacement response to objects, so it has a fast response speed, and is suitable for the places where people with normal walking speed pass. Its feature is that once people near the door do not want to go out and stay still, the radar will no longer respond, and the electric door will close, which has a certain protective effect on the door operator; The infrared sensor reacts to the existence of objects. No matter whether people move or not, as long as it is within the scanning range of the sensor, it will react and send out contact signals. The disadvantage is that the reaction speed of the infrared sensor is slow, which is suitable for places where people with slow movement enter and exit. In addition, if the electric door accepts the contact signal for a long time, the controller will think that the signal input system is blocked. Moreover, if the automatic sliding door is kept open for too long, it will also damage the electrical components. Because the microwave radar and infrared sensor do not know whether people close to the electric door really want to enter, they prefer to use the key switch in some occasions.
