Many people think that automatic doors and electric doors are the same thing, but they are actually different things. Theoretically, automatic doors should be an extension of the concept of doors, and the function of doors is developed and improved according to human needs. Automatic doors refer to a control unit that can recognize the action of a person approaching the door (or a certain entry authorization) as a door opening signal, open the door through a drive system, and automatically close the door after the person leaves, and control the opening and closing process.
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. By 1962, electric doors had begun to appear, and then with the construction of cities, the field of automatic door technology has been increasing every year. At first, it was difficult to control the speed of the motor with the power supply for the building, so we had to use oil pressure and air pressure speed control. However, the energy utilization efficiency was very low. However, with the development of electrical control technology, electrical control technology has matured, and electrical automatic doors that directly control the motor have gradually become the mainstream. For example: various automatic special doors with identifiable control, such as: induction automatic doors (infrared induction, microwave induction, touch induction, foot induction), card swiping automatic doors, etc.  
Automatic doors are different. Automatic doors are divided into: automatic doors, automatic induction doors, automatic medical doors, automatic revolving doors, automatic sliding doors, automatic swing doors, automatic curved doors, automatic overlapping doors, etc., equipped with microcomputer intelligent controllers, motors, tracks, belts, hangers, sensors, if the access control and attendance functions are realized, you can choose: fingerprint attendance, card attendance, fire linkage, etc. Among them, electric telescopic doors, electric doors, and telescopic doors are used in the entrances and exits of enterprises, factories, communities, etc.; automatic doors, automatic induction doors, automatic medical doors, automatic revolving doors, automatic sliding doors, automatic swing doors, automatic curved doors, and automatic overlapping doors are generally used in the entrances and exits of high-end buildings such as hotels, office buildings, and bathing centers.
Advantages of automatic doors:
1. A laser ceiling light is installed on the top, and the switch can be manually controlled.
2. The fur strips around the door leaf are sealed to effectively prevent dust.
3. There are automatic rotation methods and semi-automatic methods with manual operation.
4. It has a high windproof effect and can greatly improve the indoor environment of the building.
5. It has the function of stopping at a predetermined position, which is beautiful and easy to pass.

Electric doors, also known as "electric retractable doors" or "electric folding doors", are divided into ordinary type (need to be equipped with a power control box, the power part is in the control box), mechatronic type (the power part and the logic circuit are on the electrical device body. This type of electrical device has high cost performance and good reliability), and intelligent integration type (just add LCD display, electronic travel, electronic torque, remote control debugging and other functions to the mechatronics). Intelligent integration is just an update of the electrical device body. The development of intelligent integration is bus-type intelligent integration, and the update of power components, the use of inverters, and frequency conversion types.

<span Electric doors are divided into: electric telescopic doors, electric doors, telescopic doors, electric doors are divided into: tracked, trackless, equipped with tracked door control and trackless door control, LED display, fixed display and rolling display, remote control handle and desktop remote control, so that the electric door can close and open the door. Mechatronics, intelligent integration.
Advantages of electric doors 
1. In terms of use and control, there are manual and automatic control systems to meet the user's requirements for opening and closing industrial doors.
2. In terms of convenience, even manually opening and closing the sliding door is very easy, because 90% of the weight of the door has been balanced by springs or weights. These springs are individually prepared according to each door body after scientific calculation.
3. In terms of safety and reliability, when closing the door, it is equipped with door body anti-blocking, gas-sensing safety edge rebound function, or infrared sensor function. When encountering resistance or obstacles, the door control system will automatically rebound the door body to avoid accidents caused by people or trucks.
