Revolving doors, curved doors, sliding doors, emergency evacuation sliding doors, swing doors, folding doors, fast doors and other types of automatic doors began to be used in buildings after the 20th century. In the late 1920s, with the opening of American supermarkets, automatic doors began to be used. In 1930, the American Stan interest rate first introduced the world's first automatic door (this historical data was recorded in the New York Times). Later, in 1945, the world's number one automatic door brand Dorma introduced hydraulic and air-type automatic doors to the market widely, and the main entrance of new buildings also began to be used. By 1962, the electric type had begun to appear, and then with the construction of the city, the field of automatic door technology increased every year. At the beginning, it was difficult to control the speed of the motor by supplying power to the building, so oil pressure and air pressure speed control and conversion had to be carried out. However, due to the low energy efficiency, with the development of electrical control technology, electrical control technology is now mature , The electric automatic door that directly controls the motor has gradually become the mainstream. For example: all kinds of automatic special doors that can be identified and controlled, such as induction automatic doors (infrared induction, microwave induction, touch induction, pedal induction), automatic card swiping doors, etc.

Rotating doors, curved doors, translation doors, emergency evacuation translation doors, flat doors, folding doors, quick doors and other categories of automatic doors began to be used on buildings, after the twentieth century. In the late 1920s, American supermarkets opened and automatic doors began to be used. In 1930, Stanley pioneered the world's first automatic door 樘 (recorded in The New York Times). Since then, the world's first automatic door brand Doma in 1945 to the oil pressure, air automatic door widely introduced to the market, the main entrance of the new building began to use. By 1962, electricity had begun to appear, and with the construction of cities, the field of automatic door technology was increasing every year. At the beginning, the supply of power supply to buildings for motor speed control is very difficult, had to carry out oil pressure, air pressure speed control, conversion, but because of the energy efficiency is very low, but with the development of electrical control technology, now the electrical control technology has matured, direct control of the electric motor electrical automatic door gradually become mainstream. For example: a variety of automatic special doors with recognizable control, such as: induction automatic doors (infrared sensing, microwave sensing, touch sensing, foot sensing), swipe automatic doors and so on.

The rotary door, arc door, translation door, emergency evacuation flat door, flat door, folding door, quick door and other automatic doors began to be used in buildings, which was after the 20th century. In the late 1920s, the supermarket opened in the United States, and automatic doors began to be used. In 1930, the American Stan rate first launched the world's first automatic door (this historical record is recorded in the New York Times). After that, DOMA, the world's first automatic door brand, pushed oil pressure and air type automatic doors to the market in 1945, and the main door of the new building began to be used. By 1962, electrical type had begun to appear, and with the construction of the city, the field of automatic door technology was increasing every year. At first, it was difficult to control the speed of motor by supplying power supply for buildings, so it was necessary to control and convert oil pressure and air pressure speed. However, with the development of electrical control technology, the electrical control technology has been mature, and the electric automatic door which directly controls the electric motor has gradually become the mainstream. For example, various automatic special doors with recognizable control, such as: induction automatic door (infrared sensing, microwave induction, touch sensing, foot sensing), automatic door of swipe card, etc.<br>
