Automatic Door Control System and Control Method {AUTOMATIC DOOR CONTROL SYSTEM AND METHOD}

The present invention relates to an automatic door control system and a control method, and more particularly, to an automatic door control system and a control method which can simplify the structure and reduce the construction cost, and are easy in stability and expandability.

In general, automatic doors have been widely installed as conveniences that can be opened and closed automatically by power when people enter and exit. Automatic doors are mainly installed and operated at the entrances of apartments, hotels, buildings, etc., where people frequently access them. Recently, the automatic doors have been spread to general buildings such as restaurants and supermarkets as well as large buildings.

Such automatic doors may be configured to be opened and closed in various opening and closing manners depending on the installation location and use. For example, the opening and closing method of the automatic door may be divided into an opening and closing method by a sensor for detecting a person or an object, an opening and closing method by a remote control operation, an opening and closing method by a button operation, or an opening and closing combination thereof.

In general, the operation status and various abnormalities of each automatic door installed in a building or a building are configured to be monitored in real time in a central control center such as a guard room and a management station. For this purpose, each automatic door installed at different places should be able to communicate with the central control center.

However, when the automatic door system is installed in a wide area such as a large apartment complex, it is difficult to connect each automatic door and the central control center distributed in a wide area so as to communicate with each other. There is a problem that the construction of a monitoring system for monitoring the monitoring system is difficult and requires huge costs.

In particular, when each automatic door and the central control center is connected by a cable in a wired communication method, if the distance between the automatic door and the central control center is more than a certain distance, it is difficult to physically connect the cable, the installation time and installation cost There is an increasing problem. In addition, the wired connection method using a cable has a problem that it is difficult to extend the communication distance more than a certain point due to its structural characteristics, and there is a problem that the extension is not easy.

Moreover, when the cables connecting each automatic door and the central control center are communicatively connected along one line, there is a problem that all automatic door communication is cut off in the event of a short circuit or disconnection of the cable. There is a problem of this deterioration.

The present invention can simplify the structure, provide an automatic door control system and control method that can shorten the construction time and reduce the construction cost.

In addition, the present invention can extend the communication distance between the central control center and the automatic door more than a certain amount at an efficient cost, and provides an automatic door control system and a control method excellent in scalability.

In addition, the present invention provides an automatic door control system and control method capable of minimizing the interruption of communication as well as actively coping with changes such as communication errors and improving reliability and stability.
