Intelligent anti-peep control device and method thereof

The invention relates to a privacy device, and in particular to a smart anti-spy device and a method thereof.

In the current living environment, glass is widely used in a variety of applications such as architecture, decoration, lighting, etc., and is closely related to our quality of life and convenience. For example, in general buildings, transparent glass is often used as a door and window, or a glass curtain for an exterior wall. Although the aforementioned transparent glass can achieve a clear perspective and light transmission effect, it is relatively lacking in privacy.

As a result, most buildings use shutters or windows to shield sunlight and ensure privacy. However, due to the lack of convenience, some designers have proposed an electric blind or curtain. Taking electric curtains as an example, electric curtains are equipped with motors on the curtains and use a remote control to control the motor, so that the user can control the opening and closing of the curtains only by operating the remote controller. Even some of the electric windows provide the ability to turn on and off at regular intervals, adding a lot of convenience. However, the aforementioned electric window panel has certain convenience of use, but it is still necessary for the user to manually operate the remote controller to open and close the curtain, so that there is still room for improvement in convenience of use.

In addition, the exterior wall of some building buildings adopts the structure of glass curtain. In order to achieve the effect of fluoroscopy, adjusting the incident intensity of sunlight and the privacy of space, a reflective film or heat-insulating paper with a see-through effect is generally attached to the surface of the transparent glass. However, the aforementioned reflective film or thermal insulation paper has a slight anti-spying function, but if the indoor environment brightness is higher than the outdoor environment brightness (for example, cloudy or night), the building interior can be seen from outside the building. The activity of the personnel, thereby reducing the privacy of the indoor environment.

Therefore, how to provide a smart anti-spyware device, which has both convenience and privacy, has become one of the problems that researchers are trying to solve.

Embodiments of the present invention provide a smart anti-spy device and a method thereof, which can automatically control the operation of a shadow module on a window by detecting the difference in brightness between the indoor and outdoor environments and the dynamics of the indoor environment, thereby facilitating both use convenience and privacy. Sex.

The smart anti-spyware device according to the present invention includes: an environment detecting module for detecting an outdoor environment, obtaining a first brightness value, and detecting an indoor environment, and obtaining a second brightness value; The module receives the first brightness value and the second brightness value, and determines a difference between the first brightness value and the second brightness value to generate a control signal; and a masking module has a visible area, and the shielding module is configured to: Receive control signals and adjust the transmittance or range of the visible area based on the control signals.

The method for controlling the smart anti-spyware device according to the present invention includes: detecting an outdoor environment, obtaining a first brightness value, detecting an indoor environment, and obtaining a second brightness value; receiving the first brightness value and the second The brightness value is determined according to the difference between the first brightness value and the second brightness value to generate a control signal; and the control signal is received, and the transmittance or range of the visible area is adjusted according to the control signal.

The window 100b is mounted in the sash 100a, which may be constructed of electrically controlled dimming glass, tinted glass, reflective film glass, insulating paper glass, and/or clear glass. The window 100b in Fig. 5 is exemplified by a reflective film glass, and the reflective film glass has a characteristic that when the outdoor environment brightness is larger than the indoor environment, the indoor environment cannot be seen from the outdoor environment. The mounting positions of the above modules are merely illustrative and are not intended to be limiting.

When the first brightness value is greater than or equal to the second brightness value, it indicates that other people in the outdoor environment cannot see the activity of the indoor environment through the window 100b. At this time, the control module 2 controls the electric window 3a to reply or increase the outdoor environment. When the range of the visible area of the indoor environment is seen, if the original electric window 3a is fully deployed, the electric window 3a does not operate in the current state. In addition, the electric window 3a in FIG. 5 is in a semi-expanded state, and the range in which the window 100b is not shielded by the window (not shown) is called a visible area, and the visible area is covered with a window.
