Description

Window security system

The present invention relates to a window security system, and more specifically, a user can comprehensively check the opening and closing state of a window (window), and confirms in the field when an event occurs regarding the opening and closing of the window. Or it relates to a window security system that allows notification from the outside.

Conventionally known window security system is a wired / wireless security window system of the Republic of Korea Patent Registration No. 353495 by the applicant. This conventional window security system is equipped with a human body sensor on the window and by wireless transmission of the detection signal from the sensor at the time of external intrusion detection by receiving it from the main body to emit an alarm sound and at the same time to call the intrusion situation to the desired place. It was one configuration.

Since the conventional device uses a human body sensor installed in the window, the power consumption is large due to the continuous power consumption of the sensor and the wireless transmission circuit for sensing and transmitting the sensing signal of the human body sensor in real time. There was a drawback in that it cannot be used for a long time.

In addition, although the conventional security window system is configured to detect the human body approaching the window from the outside regardless of the opening and closing of the window or the lock state, it provides an auxiliary security security function in the event of malfunction or sensor failure of the sensor depending on the human body detection. No means could be taken.

The present invention devised to solve the above-mentioned conventional problems can be confirmed when there is a window or door that is not closed at the time of going out or going to bed, or if there is a problem with the locked state of the window. The purpose of the present invention is to provide a window security system having a function of alerting and notifying outside when the locked state of the lock is released.

Another object of the present invention is to provide a window security system configured to minimize the power consumption of the sensor for detecting the open and locked state of the window and the wireless transmission unit for transmitting the signal of the sensor.
