Referring to FIG. 1, the MDU control system may include a terminal 100, a common entrance 200, and an Internet of Things (IoT) platform 300.

The terminal 100 may be various types of terminals, but is assumed to be a smartphone for convenience and clarity of explanation. The terminal 100 is provided with a module that provides wired/wireless communication, and may communicate with the IoT platform 300.

The terminal 100 may register a user in the IoT platform 300 through an application that can control the apartment. In addition, zone information according to the user may be registered. The zone information may be information of a complex, dong, line, floor, etc. in which the user resides.

The terminal 100 may receive a beacon signal output from the common entrance, and recognize a beacon identifier (ID) based on the received beacon signal. The beacon ID may be stored in an application installed in the terminal 100. The beacon ID may be information for identifying a specific beacon 210 among a plurality of beacons. In order for the specific beacon 210 to be identified by the beacon ID, each beacon may have a different value of BID.

The terminal 100 may receive a beacon signal and determine whether the BID of the received beacon signal and a pre-stored beacon ID match. The terminal 100 may transmit the user's account and beacon ID information to the IoT platform 300.

The terminal 100 may receive a beacon signal and obtain information about a user's distance.

The terminal 100 may calculate the distance by using the signal strength of the beacon. The terminal 100 may determine the distance from the beacon 210 based on the change in intensity of the beacon signal. The terminal 100 may recognize the user's location based on the distance from the beacon. At this time, the user's location may be divided into first to third regions 210, 220, and 230 based on a predetermined distance. The first to third regions will be described in detail in FIG. 2 below.

The terminal 100 may transmit a control signal to the IoT platform 300 to control the common entrance when the user is located in the first area and then moves to the second area.

After requesting the common entrance control, the terminal 100 may determine whether the user is located in the third area. At this time, when the user is located in the third area, a control signal may be transmitted to the IoT platform 300 to control the elevator 400.

The common entrance may include a beacon 210 and a passive infrared (PIR) sensor.

The beacon 210 may be a device that transmits information to an external device. The beacon 210 may use a low-frequency communication method, an LED communication method, a Wi-Fi communication method, a Bluetooth communication method, or the like in transmitting the information to an external device. Of course, various communication methods other than the above-described communication methods may be used to transmit the information.

The beacon signal can be used as information for access management by the apartment house solution system. The beacon signal may acquire information on a positional relationship between the terminal 100 and the common entrance device. Through this, it can be used to determine whether to enter the common entrance.

The beacon 210 may output by giving a direction to the beacon signal to prevent malfunction. The beacon 210 may downwardly adjust left and right signal strengths of the beacon signals output in one direction in order to impart directionality of the beacon signals.

The PIR (Passive Infrared) sensor 220 may detect the presence or absence of a user around the common entrance, and output a detection result.

For example, the PIR sensor 220 may be activated by the IoT platform 300. The user can be detected in the activated state. When the user is detected, it may be activated for a predetermined time. In addition, it is possible to initialize the PIR recognition waiting time for a case where a large number of users have access to the common entrance.

The IoT platform 300 may receive a beacon ID and account from the terminal 100 and perform user authentication based on the beacon ID and account. The user authentication may be a determination that the beacon ID previously stored in the application and the occasional beacon ID do not match.

The IoT platform 300 may authenticate the user's access authority with the terminal 100.

The IoT platform 300 may activate the PIR sensor 220 based on the common entrance control signal received from the terminal 100.

The IoT platform 300 may receive an elevator control signal from the terminal when the terminal is adjacent to the common entrance door.

Referring to FIG. 2, the beacon 210 may periodically output a beacon signal having a predetermined signal strength. At this time, the beacon signal may be output every 0.5 seconds.

At this time, the beacon signal may be given directionality to the beacon signal to prevent malfunction. The beacon 210 may adjust the left and right and rear signals of the beacon signal downward to output a beacon signal in a fan shape.

The beacon signal may be output from the beacon 210 to a predetermined threshold distance.

The terminal may determine the distance from the common entrance by receiving the beacon signal. The terminal may divide the area of the beacon signal into first to third areas according to the distance from the common entrance.

The first area 210 may be an area adjacent to the first distance in the direction of the common entrance from the critical distance. The first distance 215 may be 2 to 3 m.

The second region 220 may be an area adjacent to the second distance from the first region 210 in the direction of the cavity. The second distance 225 may be 8-10 m.

The third region 230 may be a region adjacent to the third distance from the second region 220 in the direction of the cavity. The third distance 235 may be 1 to 2 m.

If the terminal 100 is not recognized in the second zone after recognizing the first zone, the terminal 100 may recognize the strength of the beacon signal again and determine the user's location.

When the terminal 100 is recognized in the first area 210 and then recognized in the second area 220, a signal for co-entry control may be transmitted (S160 ).

After transmitting the common entrance control signal, the terminal 100 may determine whether the user's location is located in the third region 230 (S170). If it is not located in the third region 230, the user's location may be determined again.

When the terminal 100 is located in the third area 230, an elevator control signal may be transmitted (S180). At this time, the called elevator may be an elevator corresponding to the beacon ID received by the terminal 100.

It may be determined whether the PIR sensor 220 recognizes the user within 5 seconds.

When the PIR sensor 220 recognizes the user within 5 seconds, it may be controlled to open the common entrance. Thereafter, it is possible to initialize the PIR recognition waiting time for a case where there are a large number of access users.

If the PIR sensor 220 does not recognize the user within 5 seconds, the PIR sensor 220 may be deactivated.
