随着计算机、通信技术的高速发展，各种促进生活的自动控制系统逐步进入步入

With the rapid development of computer and communication technology, various automatic control systems that promote life have gradually entered our field of vision. At present, there are many methods to control automatic doors at home and abroad, but in practice, quite a lot of automatic door systems generally adopt logic control modules, which have shortcomings such as high failure rate, low reliability, and inconvenient maintenance. In the research and design of automatic door control systems, stability, safety and reliability are the first factors that people consider. And PLC has the advantages of versatility, strong adaptability, perfect fault self-diagnosis ability, easy maintenance, high reliability and strong flexibility, and the price of small PLC is also very cheap and common in modern society. <br>Up to now, the automatic door has developed into a complete range of automatic doors with complete functions and fine craftsmanship. In order to add more beautiful and fashionable decorations to large and medium-sized public buildings, reliable and attractive automatic doors are used. Theoretically understanding of automatic doors should be the extension and progress of doors. According to people's needs, the improvement and improvement of automatic doors should be strengthened. Therefore, the understanding of automatic doors should start from people's requirements for various functions of automatic doors. In the most basic sense, the door as a part of a public building must meet the two requirements of isolating the external environment and not obstructing the passage of people. Therefore, the door itself should be firm and sealed. The popularization and application of automatic doors have changed people's awareness of protection and improved people's awareness of automatic doors. Since the automatic door can be unattended after being energized, it can also save air-conditioning energy, wind and dust, and reduce noise. It is convenient and improves the quality of public buildings. At the same time, it has almost become an indispensable part of other places. Item configuration. <br>With the improvement of people's living standards and the acceleration of social development, people are paying more attention to the convenience of life, the safety of construction, and the environmental protection. Automatic door products just meet people's various needs. Compared with the traditional structure of the door, the automation of the automatic door greatly reduces the labor intensity of the door and improves the efficiency of people's passage. The advanced control technology and safety protection measures adopted make the automatic doors safer and more reliable for people entering and exiting.

With the rapid development of computer and communication technology, all kinds of automatic control systems to promote life gradually enter our field of vision. At present, there are many methods for controlling automatic doors at home and abroad, but in practice quite a few automatic door systems generally use logic control module control, high failure rate, low reliability, inconvenient maintenance and other shortcomings. In the research and design of automatic door control system, stability, safety and reliability are the first factors that people consider. PLC has universality, adaptability, with perfect fault self-diagnosis ability and convenient maintenance, high reliability and flexibility and other advantages, and the price of small PLC is currently very cheap universal and modern society.<br>Automatic door development to now, has formed a complete range, perfect function, fine construction of automatic door. Large and medium-sized public places in order to add more bright, stylish decoration using reliable and good-looking automatic doors. Automatic door from theory understanding should be the extension and progress of the door, according to people's needs to strengthen the automatic door promotion and improvement, so the understanding of automatic door should start from people's automatic door function requirements. As part of a public building, the door, in the most basic sense, to meet the isolation of the external environment and do not hinder the passage of people these two requirements. Therefore, the door body itself should be firm and sealed. The popularization and application of automatic door has changed people's awareness of protection and raised people's awareness of automatic door. Because the automatic door can be unattended after power, but also can save air-conditioning energy, wind and dust, reduce noise, not only convenient and improve the quality of public buildings, but also almost become an indispensable decoration of other places a configuration.<br>With the improvement of people's living standards and the progress of social development, people pay more attention to the convenience of life, building safety and environmental protection. Automatic door products just meet people's needs. Compared with the traditional structure of the door body, the automatic door automation, greatly reduce the labor intensity of the door and improve people's pass efficiency. The use of advanced control technology and safety protection measures, so that people access to automatic doors more secure and reliable.

With the rapid development of computer and communication technology, various automatic control systems to promote life have gradually entered our vision. At present, there are many methods to control automatic door at home and abroad, but in practice, a lot of automatic door systems generally adopt logic control module control, such as high failure rate, low reliability, inconvenient maintenance and other shortcomings. In the research and design of automatic door control system, stability, safety and reliability are the first factors to be considered. PLC has the advantages of generality, adaptability, perfect fault self diagnosis ability, convenient maintenance, high reliability and flexibility, and the price of Small PLC is very cheap and common with modern society.<br>Automatic door has developed to now, has formed a complete variety, perfect functions, fine manufacturing of automatic doors. Large and medium-sized public space buildings use reliable and beautiful automatic doors to add more beautiful and fashionable decoration. The understanding of automatic door should be the extension and progress of the door theoretically. According to the needs of people, the improvement and improvement of the automatic door should be strengthened. Therefore, the understanding of automatic door should start with the requirements of various functions of the automatic door. As a part of public buildings, the doors should meet the requirements of isolation of external environment and non obstruction of people's passage in the most basic sense. Therefore, the door body itself should be firm and sealed. The popularization and application of automatic door has changed people's awareness of protection and improved people's cognition of automatic door. Since the automatic door can be unattended after power on, it can save air conditioning energy, wind and dust, reduce noise, which not only improves the class of public buildings, but also becomes an indispensable configuration for other places decoration.<br>With the improvement of people's living standard and the progress of social development, people pay more attention to the convenience of life, the safety of building and the environmental protection. Automatic door products meet the needs of people. Compared with the traditional gate, the automation of automatic door greatly reduces the labor intensity of human door and improves people's efficiency. The advanced control technology and safety protection measures adopted make people more safe and reliable to access the automatic door.<br>
