| 自动门的基本工作原理自动门机的基本组成大体上相同，有了以上构成，再加上开门信号，就可以配置成一套简单的自动门系统了。 The basic working principle of the automatic door, the basic composition of the automatic door machine is basically the same, with the above composition, plus the door opening signal, you can configure a set of simple automatic door system. 自动门的系统配置是指根据使用要求而配备的，与自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 automatic door refers to the peripheral auxiliary control devices connected with the automatic door controller according to the use requirements, such as door opening signal source, access control system, safety device, centralized control, etc. It must be based on the use characteristics of the building. Through the composition of personnel, building automation system requirements, etc., reasonably equipped with auxiliary control devices. 解锁 Unlock 自动门解锁动作与开门动作之间的协调，应用于自动平移门的电子锁有锁皮带的电磁锁和锁门体吊挂件的电动锁，锁电机的三种。后者用于重型自动平移门，自动平开门的电子锁有电磁门吸，电子插销锁和电子开门器，电子开门的作用力方向不影响门的开启动作，不易发生误操作。还有一种带触点开关的机械锁，使锁与开关结合，锁不处于开锁状态，触点就不能接触，不可能发生误操作。 There are three kinds of electronic locks used in automatic translation door, such as electromagnetic lock of lock belt, electric lock of hanging parts of lock body and lock motor. The latter is used for heavy-duty automatic translation door. The electronic lock of automatic side opening door includes electromagnetic door stopper, electronic bolt lock and electronic door opener. The force direction of electronic door opening does not affect the opening action of the door and is not prone to misoperation. There is also a mechanical lock with contact switch, so that the lock and switch are combined. If the lock is not in the unlocking state, the contact can not be contacted and misoperation is impossible. 集中控制 centralized control 集中控制的概念，包括集中监视自动门运行状态和集中操作多个自动门两层含义，集中监视自动门开门关门状态可以通过位置信号输出电路来实现，可以采用接触式开关，当门到达一定位置（如开启位置）时，触动开关而给出触点信号。也可以采用感应式信号发生装置，当感应器探测到门处于某一位置时发出信号。在中控室设置相应的指示灯，就可以显示自动门的状态，而集中操作通常指同时将多个门打开或锁住 The concept of centralized control includes centralized monitoring of automatic door operation state and centralized operation of multiple automatic doors. Centralized monitoring of automatic door opening and closing state can be realized by position signal output circuit, and contact switch can be used. When the door reaches a certain position (such as open position), the contact signal is given by touching the switch. An inductive signal generator can also be used to signal when the sensor detects that the door is in a certain position. Setting the corresponding indicator light in the central control room can display the status of the automatic door, while centralized operation usually refers to opening or locking multiple doors at the same time 开门信号 enabling signal 自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： The opening signal of automatic door is contact signal. Microwave radar and infrared sensor are two common signal sources 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，自动门就会关闭，对门机有一定的保护作用。 Microwave radar is a response to the displacement of objects, so it has a fast response speed. It is suitable for the places where people with normal walking speed pass through. Once the personnel near the door do not want to go out and stay still, the radar will no longer react, and the automatic door will be closed, which has a certain protective effect on the gantry crane. 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。 The infrared sensor reacts to the existence of the object. No matter whether the person moves or not, as long as it is in the scanning range of the sensor, it will react, that is, the contact signal is sent out. The disadvantage is that the reaction speed of the infrared sensor is slow, which is suitable for the places where there are slow moving personnel. 另外，如果自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自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。 In addition, if the automatic door receives 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 a long time, it will damage the electrical components. Because microwave radar and infrared sensors do not know whether people approaching the automatic door really want to enter the door, they prefer to use the key switch in some occasions. 按键开关可以是一个触点式的按钮，更方便的是所谓肘触开关。肘触开关很耐用，特别是它可以用胳膊肘来操作。避免了手的接触。 The key switch can be a contact type button, more convenient is the so-called elbow touch switch. Elbow switch is very durable, especially it can be operated with elbow. Hand contact is avoided. 还有脚踏开关，功能一样，但对防水的要求较高，而且脚踏的力量很大，容易使脚踏开关失效。还有一种带触点开关的拉手，当拉手被推（或在反方向拉）到位时，向门机提供触点信号。 There are also foot switches, the same function, but higher requirements for waterproof, and the foot power is very large, easy to make the pedal switch failure. There is also a handle with contact switch. When the handle is pushed (or pulled in the opposite direction) in place, it provides contact signal to the door motor. 楼宇自控有时会提出特殊的要求，例如使用电话的某一分线控制开门。要达到这个要求，只要保证信号是无源的触点信号即可。有些情况下，人们会提出天线遥控的要求。用一个无线接受器与自动门进行触点式连接，再配一个无线发射器，就可以达到要求。 Building automation sometimes puts forward special requirements, such as using a branch line of the telephone to control the door opening. To achieve this requirement, as long as the signal is a passive contact signal. In some cases, people will put forward the requirements of antenna remote control. With a wireless receiver and automatic door contact type connection, with a wireless transmitter, you can meet the requirements. |
