In addition to the advantages of traditional automatic doors, the new magnetic levitation automatic door also has the special features of low noise and flexible operation.
Automatic doors began to be used in buildings after the 20th century. In the late 1920s, with the opening of supermarkets in the United States, automatic doors began to be used. In 3 years, American Stanley took the lead in launching the world's first automatic door (this historical data was recorded in the New York Times). Later, the world's No. 1 automatic door brand, Dorma, widely introduced hydraulic and air-type automatic doors to the market in 2006, and began to use them at the main entrances of new buildings. By 2000, electric doors had begun to appear. Later, with the construction of cities, the field of automatic door technology increased every year. At first, it was difficult to control the speed of the motor with the power supplied to the building, so we had to control the speed of oil pressure and air pressure. However, the energy utilization efficiency was very low. However, with the development of electrical control technology, electrical control technology has matured. Electric automatic doors that directly control the motor are gradually becoming mainstream. For example: various automatic special doors with identifiable control, such as: induction automatic doors (infrared induction, microwave induction, touch induction, foot induction), card automatic doors, etc.
There are several main methods for operating modern automatic doors.
① Foot pedal type: There is a pressure switch under the pedal.
② Photoelectric beam type: Set up a beam emitting device and a photoelectric sensing device near the door.
③Button method: Press the button similar to a switch with your hand to open the door leaf. Automatic doors open and close doors by sliding, hinged or folding methods. In order to prevent theft, special equipment must be installed. For example, automatic doors for homes need to be equipped with visitor identification devices or TV monitors, which strictly restrict people outside the home. Automatic doors have been widely used in shopping malls, hotels, restaurants, airports, stations, banks and other places.
④Microwave induction type: Microwave radar responds to the displacement of objects, so it responds quickly. It is suitable for places where people with normal walking speed pass by. Its characteristic is that once the people near the door do not want to go out, they will remain still. After that, the radar will no longer respond, and the automatic door will close, which has a certain protective effect on the door operator
