Hereinafter, with reference to FIGS. 2 to 7, the method (S100) for reducing power consumption of the window handle assembly 10 described above will be briefly described.

First, the window handle assembly 10 is operated in a standby mode by the control unit 150 (S110).

Here, the standby mode of the window handle assembly 10 is activated approximately every 5 minutes.

At this time, the window handle assembly 10 transmits information such as window status information and indoor air information from the open/close detection unit 130, vibration detection unit 180, and air quality detection unit 170 to the control unit 150.

For reference, window ventilation guidance is provided to the user through the display unit 160 of the window handle assembly 10 or the application 32 of the terminal 30 using the window status information and indoor air information transmitted to the control unit 150. Information can be provided.

In addition, when the window handle assembly 10 operates in the standby mode, connection with the communication unit (not shown), outdoor weather information transmitted from the server 20, and errors in the window handle assembly 10 Check continuously.

Next, the time after operation in standby mode is monitored (S120).

In other words, the control unit 150 detects how much time has elapsed since the window handle assembly 10 was operated in the standby mode.

For example, the window handle assembly 10 determines whether 20 seconds have passed since the standby mode operation began.

If it is determined that the time elapsed after the window handle assembly 10 operates in the standby mode does not exceed a predetermined time, for example, 20 seconds, the process returns to the standby mode operation step (S110).

Conversely, if it is determined that the time elapsed after the window handle assembly 10 was operated in the standby mode exceeds a predetermined time, the window handle assembly 10 is operated in the power saving mode (S130).

Next, a change in the state of the window handle assembly 10 is detected (S150).

In other words, a change in the state of the window handle assembly 10, that is, a change in the state of the window is detected by the opening/closing detection unit 130 and the vibration detection unit 180 of the window handle assembly 10.

Here, before detecting a change in the state of the window handle assembly 10 (S150), the monitoring time after operation in the standby mode is initialized (S140).

In this way, initializing the monitoring time after the window handle assembly 10 operates in the standby mode is intended to improve reliability when monitoring the elapsed time after the window handle assembly 10 operates in the power saving mode.

Meanwhile, when a change (or event) in the state of the window is detected by the opening/closing detection unit 130 and the vibration detection unit 180 of the window handle assembly 10, the return to the standby mode operation step (S110) is performed. Goes.

Conversely, in the step of detecting a change in the state of the window handle assembly 10 (S150), if it is detected that the state of the window has not changed, time monitoring is performed after the power saving mode operation (S160).

If it is determined that the elapsed time after the window handle assembly 10 operates in the power saving mode exceeds a predetermined time, for example, about 5 minutes, the process returns to the standby mode operation step (S110). Conversely, if it is determined that the elapsed time after the window handle assembly 10 operates in the power saving mode does not exceed a predetermined time, the process returns to the monitoring time initialization step (S140).

Meanwhile, in the step of detecting a change in the state of the window handle assembly 10 (S150), as described above, when it is detected that the state of the window handle assembly 10 has changed, it returns to the standby mode. At this time, the status change information of the window handle assembly 10 is sent to the user through the communication unit (not shown) of the window handle assembly 10 through the display unit 160 of the window handle assembly 10 or the application 32 of the terminal 30. ) can be informed through.
