Translational automatic doors unit consists of the following components: (1) the primary controller: it is the command center of automatic doors, through an internal instruction program compiled a massive blocks, issue the appropriate command, directing motor or electric locking system working class; At the same time people adjust speed by master door open, open the amplitude and other parameters. (2) induction detectors: responsible for the acquisition of external signals, automatic doors as people's eyes, when there are moving objects into its operating range Xinzhou automatic doors, it is a pulse signal to the main controller; (3) the power of the motor: provide open and close the active force, acceleration and deceleration control the doors. (4) Doors traveling track: like train tracks, bound to go round the doors of the spreader system, it travels in a specific direction. (5) to go round the doors spreader system: activities for hanging the doors, the doors while driving traction run power. (6) the timing belt (some manufacturers use the V-belt): transfers motor power produced Luliang automatic doors, pulling the doors to go round the spreader system. (7) The lower-oriented system: the lower part of the leaf orientation and positioning device to prevent the doors before and after the door swing at runtime. Automatic doors into: revolving doors, curved doors, sliding doors, electric door sensors, emergency evacuation sliding door, overlapping doors, folding doors, multiple classes of 90 degrees late twenties opened the door, quick doors, American super market opening, automatic doors began to be used. 1930, the United States Stanley pioneered the world's first automatic door jamb (this historical records in New York Times). Thereafter, the world's first automatic doors brand Sodom in 1945 will be hydraulic, pneumatic automatic doors widely to the market, the main entrance of the new building is also ready to use. To 1962, has begun to appear in Taiyuan electric type automatic door, then along with the city's construction, automatic doors technology field are increasing every year. At first, the supply of buildings with a motor speed control with power is difficult, but to be hydraulic, pneumatic speed control, but low conversion efficiency of energy use, however, accompanied by technological development of electrical control, electrical control technology has matured, Direct control of the motor electric automatic door becoming mainstream. For example: all controls can be identified with a special automatic doors, such as: automatic door sensors (infrared sensors, microwave sensors, touch sensors, foot sensors), credit card automatic doors.
