How does the automatic door realize non-contact entry?
How do automatic doors work?
History of automatic doors
The automatic door allows people to pass through the entrance channel without touching the door so as to realize non-contact entry. People prefer non-contact access because automatic door eliminates the need to touch high-risk surfaces. If you want to achieve contactless access in multi-family residential buildings or restricted commercial properties, you need automatic doors and access control systems or video walkie talkies. Automatic doors controlled by cloud-based access control system or intelligent video walkie talkie are ideal for multi-family residential buildings and commercial properties, which only need to be authorized to enter. Most multi-family residential and commercial buildings require access control systems or video walkie talkies to comply with fire and safety regulations. In addition, the access control system and intelligent video walkie talkie improve the residents' experience.
The automatic door itself is equipped with an induction probe that can emit an infrared signal or microwave signal, when the signal is reflected by the object close to it. The door will realize the automatic opening and closing. When the induction detector of automatic door detects someone entering, it will collect signals and generate pulse signals, which will then be transmitted to the main control device. The main control device will inform the motor to run after judgment, and monitor the motor revolution at the same time so as to inform the motor to increase force and enter slow operation at a certain time. When the motor gets a certain running current, it runs forward and transmits the power to the synchronous belt. Then the synchronous belt transmits the power to the spreader system to make the door open. After the automatic door is opened, the controller will make a judgment. If it is necessary to close the automatic door, the motor will be informed to move in reverse to close the door.
In the first century AD, a Greek mathematician called Alexander Heron may be the first person to put forward the concept of automatic door. He called it machine 37. In fact, he formed a clever mechanical arrangement under the altar in front of the huge temple. When the priest comes forward and lights the fire on the altar, the heat will kick the counterweight and pulley arrangement under it into action, and then open the door. At that time, such an arrangement was regarded as a miracle. As a sign that the gods are happy with the priest, then open the door to thank him for his service! Many centuries later, in 1931, engineers Raymond and Robbie proposed the idea of a universal automatic door. Their design was patented and the first automatic door opening system was installed in a restaurant in Connecticut. The staff of the hotel were impressed by the miracle of the project. Waiters can now walk around, although their hands are in contact with plates and cups, and there is no need to manipulate the door handle clumsily! Now, entering the modern automatic door system, most of them are composed of sensors, which can help trigger the opening or closing of the door when needed.
