Description

Technical field

The technical solution relates to an electronic security device for apertures, in particular windows or doors, in particular for additional security of apertures, especially windows, doors.

BACKGROUND OF THE INVENTION

At present, the security devices for detecting the closed or other state of windows, doors and the like (hereinafter referred to as the "hole fill"), are mainly used hidden contact switches, which are usually wired to other equipment usually outside the monitored hole fill. This solution usually requires power supply from an external source located outside the monitored opening filler. Known security devices are also based on the principle of measuring the change in resistance for detecting a closed or other state of the orifice filler, by wiring connected to other devices, typically outside the orifice filler being monitored. This solution also usually requires power supply from an external source located outside the monitored opening filler. In addition, the vast majority of the devices known to date only fulfill their functionality when it is necessary to communicate with another system.

They are also currently known in security devices for detecting the closed or other state of apertures, based on the principle of evaluating the magnetic field caused by a change in the position of the aperture leaf. The disadvantage of these solutions is that in the vast majority of solutions the security device based on the principle of magnetic field evaluation is not autonomous and must be connected by cabling to a superior system, which is usually located outside the monitored opening filler. Another major disadvantage of these solutions is the need to use a counterpart located near the magnetic sensor in a security device based on magnetic field evaluation. This counterpart is usually made of permanent magnetic material. In addition, such devices can very often be rendered inoperative by the use of another permanent magnet (s). Last but not least, it is a major disadvantage that, in the case of autonomous security devices based on magnetic field evaluation, which do not have lead-in cables and are powered from their own power supply, the size of the device usually prevents the installation of this directly in doors and the like to ensure that the device is hidden.

The essence of the technical solution

The above-mentioned deficiencies are largely solved by the security system according to this technical solution. The principle of the technical solution of the invention is the measurement and evaluation of the change in the magnetic field caused by the change of the position of the wing of the orifice without the necessity of using a counterpart of permanent magnetic material, using its own autonomous energy source. The entire security device is located in the blind portions of the opening. This technical solution ensures the elimination of the above disadvantages as follows. The device uses a sensitive magnetometer, which is able to measure even weak magnetic fields of the surroundings. Since the device is very sensitive to magnetic field changes, it is not possible to disable it using another permanent magnet. In the case of very weak magnetic fields around the aperture, the device is able to evaluate the position of the aperture by changing the rotation relative to the Earth's geomagnetic field. The device is equipped with an autonomous energy source. The whole device is autonomous and therefore does not need any power cables. Also, the size of the device is small and is located, including the power source, in the inner groove of the orifice filler or spacer frame of the orifice filler. Furthermore, the security device may be provided with a touch control for manual operation. This device can also be equipped with an audio alarm output or a wireless communication module for information transmission. It can also be equipped with a solar cell to add energy to the source of this device.
