Product of human civilization, automatic doors have been dozens of years of development, so far, through the application of PLC control system and other technology products, already have and its control technology, formed the large scale automatic door of the family. And according to different requirements, formulated a series of standards. People's Republic of China in the 2005-12-01 standard of China automatic door number, standard content mainly include: rules for building the classification of the various kinds of automatic door, specifications, codes, materials, requirements, test methods, inspection rules and signs, packaging, transport and storage. This standard applies to push-pull automatic door automatic doors (arc), fold the flat open automatic doors, automatic doors, revolving doors. You may refer to other automatic door. Have special requirements of automatic doors, still should see its related standards.Door and human civilization is a twin, it is accompanied by the development of human civilization and chatter. For thousands of years, the door has been as the patron saint of the human society activities, intruder in the room, and as a channel of human social activities, carrying the door and civilization, pursuing people to yearn for the glory of the other shore.Human desire is endless to civilization. From ancient Egypt to Roman to today's modern society, can see the door move.Past, passive isolation barrier function of the door is, and the channel role is to ensure that only traffic.Today in the 21st century, the door even more highlighted safety concept, emphasizes the effectiveness: effectively prevent, passage, evacuation, and also highlights the concept of architectural art, door and building and the surrounding environment coordination, the harmonious whole.

Door advanced forms of automatic door originated in Europe and the United States, in August 1802, the German standard company successfully designed and developed the world's first sensing automatic doors, door large-scale specialized production began in the 150 years ago, in the process of constant development and perfection, emerged a large number of scale of professional manufacturers. Rapid development to today, has formed a complete kinds, function perfect, workmanship fineautomatic door of the family.China as early as more than a decade ago began to

refer to the automatic doors, and apply it in the hotel, airport, shopping centers, Banks, office buildings and other large and medium-sized public places, for these buildings added bright beautiful, chic, colorful.Automatic door according to the different use function and can be divided into automatic sliding door, automatic door, automatic revolving door, automatic arc door, automatic folding door, etc., including flat door with fewer occasions, revolving door due to the expensive and very big, only commonly used in high-grade hotels, in need automatic sliding door is most widely used, people generally say automatic door, automatic induction door is sliding door.Automatic sliding door is the most common form of automatic door machine add radar on both inner side and outside of the door, automatic door when the man came near, the radar by emitting microwave induction to man's existence, open the door to the controller a signal, the controller through the drive to open the door. When the man by the door, and then closed the door.Another form of infrared sensor, mainly through the infrared to feel the temperature changes within the specified range, when people walk into, microwave induction the emission signal control changes in the door.

Microwave sensors and infrared sensors difference is mainly: microwave sensor, also known as microwave radar, reaction to the movement of the object, and reaction speed, suitable for walking speed normal personnel through the place, its characteristic is that once the door near the staff don't want to go out and motionless, radar will no longer response, automatic door will be closed, likely clamping phenomenon. Infrared sensors, exist in response to the object, regardless of whether or not mobile staff, as long as in sensor scanning range, it will respond. Reaction speed is slower than the microwave sensor of infrared sensors.

According to different requirements of some, some manufacturers in the production of automatic doors can increase some personal function, facilitate the management and maintenance. Such as fuzhou blue electronic co., LTD., automatic door, it has the following characteristics: 1, automatic door sensors react to the movement of objects in microwave, sensitivity is adjustable, stable performance! 2, automatic encryption gather multi-function remote control into an organic whole, the induction door for encryption, can avoid the project appears on the welsh, bad debts, etc. Phenomenon, thus effectively protect the interests of dealers, at the same time, can realize the remote control to open the door, always open, lock, unlock; Has connected to the card reader, fingerprint, home button, peripheral devices, such as electric lock functions. 3, safety light can effectively overcome the blind area of
