As shown in Figure 3, when the electric power is supplied to the automatic door opening and closing system according to the present invention through an external power source or a battery, the automatic door opening and closing system is in a state capable of operation (S100).

When the operation is enabled and the user does not set the operation mode in particular, the door side wireless transmission / reception module 201 of the automatic door opening / closing system first antennas the user's unique ID code at 10ms to 100ms with the lowest wireless output. Transmit through (S101).

The door side wireless transmission / reception module 201 checks whether a response reception is issued from the user side wireless transmission reception module 200 with respect to the transmitted ID code (S102). When the response signal to the transmission signal is received, it is checked whether the response signal is received several times in succession for error checking of the received response signal (S103). If the response signal is not received several times in succession, go to the sending step of the ID code, and if the response signal is received several times in succession, check the opening and closing state of the door (S104). As a result of the check, if the door is in the open state, the step of transmitting the ID code is continued, and if the door is in the closed state, a "door open" signal is output to the door opening and closing means (S105).

If the response signal for the transmission signal is not received, the door-side wireless transmission / reception module 201 transmits a unique ID code of the user through the antenna at a period of 10ms to 100ms with the maximum wireless output (S106). The door side wireless transmit / receive module 201 checks whether a response is received from the user side wireless transmit / receive module 200 with respect to the transmitted ID code (S107). When the response signal to the transmission signal is received, it is checked whether the response signal is received several times in succession for error checking of the received response signal (S108). As a result of the check, if the response signal is not received several times continuously, the step of transmitting the ID code with the same maximum wireless output is repeated, and if the response signal is received several times successively, the opening / closing state of the door is checked (S109). As a result of the check, if the door is in an open state, a "door closing" signal is output to the door opening and closing means, and if the door is in a closed state, an "access signal light" control signal is output. Here, the "access signal light" control signal refers to a control signal that causes the tail light of the vehicle to blink, for example.

Through the above operation flow, the door is automatically opened and closed when the user approaches the door or moves away from the predetermined distance. Therefore, there is an advantage that the door can be easily opened and closed even for the elderly or disabled people are not familiar with the operation of the device.

In addition, in the embodiment of the present invention by dividing the wireless output into four stages of lowest → low → high → highest, and periodically changing these outputs to perform communication, when there is a response signal only at the highest output and no response signal at the other output If there is a response signal only at the highest and high output and no response signal at the other output, if there is a response signal up to the low output and no response signal at the lowest output, there is a response signal at all outputs. The location is estimated in multiple stages, and based on this, various services can be provided.

For example, in the case of a vehicle door, when the user approaches the high output stage from the vehicle, the tail light of the vehicle blinks in advance, so that the user can easily identify the position of the vehicle and open the vehicle door when the user approaches the minimum output stage. As a result, in the present invention, a function that was possible only by artificially manipulating a device such as a remote controller can be performed without artificially manipulating the user.

On the other hand, in the embodiment of the present invention, the unique ID code is divided into four categories and can be used to integrate the classified codes.

The first classification of the unique ID code is a production serial code, which is a code for copying or using a product according to the present invention from the outside after shipment of the product or determining an error in production management. In addition, the second classification is a random number assigned to each product as a lost code, and is preloaded on each wireless transmission / reception module. When the first code of the lost code array is used and the lost code is lost, the second code is used to prepare for the loss. Is the code. In addition, the third classification is a code for allowing a large number of users who make up a family member to open and close the same door by using a family code. . In addition, the fourth classification is a code for making a group code to be used together with a home, a vehicle, a company, and the like.

The embodiments of the present invention are not intended to limit the technical spirit of the present invention, but those skilled in the art to which the present invention pertains may make various modifications or changes without departing from the essential characteristics of the present invention.

The automatic door opening and closing system according to the present invention is open and close the door without the artificial manipulation of the user can be easily opened and closed even the disabled or elderly people difficult to operate the device.

In addition, the automatic door opening and closing system according to the present invention has the advantage that it is possible to determine the location of the user-side wireless transmission and reception module in a multi-level through the adjustment of the wireless output stage, it is possible to provide a variety of services accordingly.

In addition, the automatic door opening and closing system according to the present invention is not applied to a house or a vehicle, but separately by a classification of a unique ID code, it can be applied integrally, so that opening and closing control of various doors is possible with only one key. This eliminates the inconvenience of the user having to carry multiple keys.
