Abstract

The sensor has electronic and mechatronic components that are strongly shortened in such a manner the components are integrated in the form of a window catch with standardized connecting dimensions and shaping. A power supply has solar cells (g) placed on a contour of the catch. An antenna system (c) is provided based on whose signal signatures and/or levels identification characteristics of an authorized alarm center are recognized.

Description

The The invention relates to a window handle in an embodiment according to the relevant Construction standards and connection dimensions, as well as in a usual outer shape.

In integrated into the handle is a microsystemically designed motion sensor, which the position of the handle and tilt and tilt of the window frame recognizes. Furthermore, the motion sensor detects vibrations the window pane (glass breakage and glass cut).

through a built-in antenna system with transmitting and receiving devices can all important monitoring parameters the window and the glass panel wirelessly transmitted to a central alarm system become. So the sensor can break glass, cut and shake the glass pane, as well as the opening (Handle position corresponds to 3 o'clock position), tilting (handle position corresponds to 12 o'clock position) and the lock (handle position corresponds to 6 o'clock position) of a window sash.

The inevitability between handle position and window position, which originally a Prevent operating errors and falling out of the window from the frame should deliver for the sensor so far reliable Dates.

The resolution modern sensors is extraordinary high, so that burglary attempts are registered.

Of the Sensor has one self-sufficient energy supply. For this purpose, the handle with one to the window side directional arrangement of solar cells equipped, the one for the sensor and the electronics produce usable operating voltage.

In an advantageous embodiment These solar cells are designed as a flexible element, so that the arched facing the window surface of the handle for the attachment can be used. Flexible solar cells in shape Plasma-coated titanium or stainless steel sheets are already in the state of the art Technology.

During the Night or longer Phases without sufficient light is the sensor over a rechargeable energy storage buffered. The sensor can thus even for a few weeks without incident light, for example if the shutters during to stay closed.

alternative The window handle can take its energy from one between the handle and the window lock mechanism arranged thermoelectric Gain the element. Microsystemically designed Peltier elements as thermal generators are already state of the art.

The Elements grasp the inevitably resulting temperature difference between the integrated window mechanism (mean value between cooler outside temperature and warmer room temperature) and the temperature of the room temperature, which is largely equal to room temperature inside window handle.

So arise, for example, during the winter months temperature differences between indoor and outdoor temperature from above 18 degrees, which is one for the thermocouples should result in useable difference of at least 9 degrees. Such a temperature gradient is sufficient enough energy for the rest warmer Save months of the year in the battery.

The Measurement data from the sensor are wirelessly sent to a central alarm system where it is further processed according to the security concept of the respective building become.

Of the Window handle has one or more centrally mounted antennas using a specific antenna Radiation characteristic one or more existing in radio communication Capture identification elements. Through movements of the window or of the window handle, these identification elements leave the detection area of the central antenna system or change your signal characteristics such that this movement is detected at the central antenna system can be. Thus, it is clear that communication is not with the authorized alarm center takes place, but a jammer into the system.

A advantageous embodiment these sensors would the precise one Definition of an alarm threshold by a "teach-in process" (i.e. all operating states and the storage of the associated sensor and antenna signatures) enable.

The Measurement data is transmitted by means of a transceiver semiconductor module, which advantageously radiates at a transmission frequency of 868 MHz transmitted.

The determined acceleration data are in the form of an overall picture recorded and electronically archived. These data can be accessed continuously wireless building surveillance system transmitted to a PC and pictured there.

These Presentation allows the security expert to track event histories and the initiation of appropriate security-related measures.

at the surveillance objects must be closed of windows and a possible glass breakage safely and promptly detected become.

The available today Glass breakage sensors and magnetic contacts for monitoring windows and glass surfaces are only singular Sensors, i. they only recognize one monitoring parameter each:

Glass break sensors

For monitoring of glass surfaces breakthrough so-called glass-breakage sensors are used. These are attached to the disc with a special adhesive and react like a microphone, which is set to the high frequencies is that arise when breaking glass. The adaptation to the Different types of glass and the associated triggering characteristics, must to make a professional.

acoustic sensors

The Acoustic sensors react - similar to the Glass breakage sensors - on the high frequencies, which when breaking a Disc arise. The advantage, however, is that these acoustic sensors do not need to be attached to the glass, but be mounted at a certain distance from the pane in the room. Thus, a single acoustic sensor can monitor multiple slices simultaneously.

vibration contacts

vibration contacts will also be monitored Element (frame or glass) attached and respond by a special Spring mechanism (today also with an electronic evaluation) on Attacks on this element.

magnetic contacts

For monitoring of window sashes and doors against unauthorized opening Magnetic contacts are used. A magnetic field through a round magnet on the wing generates, holds a so-called reed contact at rest, as long as the wing closed is. Will the wing now open and the magnetic field of the round magnet weakens, the reed contact also opens and solve thus an alarm. Good alarm systems have magnetic field-safe magnetic contacts. These are from the outside not manipulatively influenced by other magnetic fields.

Alarm glass windows and locking sensors

A modern design the sensors is the direct steaming of the glass panes with electric Resistor tracks, as well as the installation of a locking sensor in the window mechanism. However, these windows must be secure already be provided during the construction of the object and are clear more expensive than later to be attached sensors.

The mentioned sensors are disadvantageous for several reasons. A weakness is their ease of manipulation (e.g., by icing from the outside), as well as the wired signal forwarding, the costly installation necessary. So costs for the installation of the sensor ever After removal to the alarm system usually a multiple of the actual Sensor.

ever after security need the operator should not only broken glass, but also the shutter of the element (open or tilted). This makes more Contact sensors necessary, which cause additional costs. Depending on the requirements of insurance can here to obtain a Cover commitment a considerable effort be prescribed. Of the Association of property insurers has three safety classes in this regard which require different levels of investment. From a certain insurance value is the highest security class (VdS C) almost always prescribed.

radio-operated Alarm systems have only been around for about two years by the VdS until Safety class B recognized, currently the first plants certified with class C.

Of the Invention is the object of the problems addressed to solve.

The to be solved Problem for the developer is to miniaturize a sensor so far that he is called "Smart Handle "at each Window or on every glass door can be attached. This sensor should as many different Record alarm parameters and transmit its data wirelessly to the central reporting unit. It should with simple tool and without interfering with the existing Be building fabric and remove again.

Receiver for the monitoring data is a PC that automatically sends the signals to the existing alarm reporting unit integrated and, if necessary, triggers an emergency alarm.

For this task, there are still no satisfactory solutions. The market Systems available today, for example from Bosch Sicherheitstechnik GmbH (DS 271), Siemens Fire & Security GmbH (Alarmcom) and eff eff Alarm (MS 7730), as well as corresponding devices from Telenot work with wired sensors.

Partially transmitted these systems alarm data over a radio link between an attached near the window Box, which is wired to the sensors and a receiving station. None of the ones available on the market Sensors is capable of multiple monitoring parameters simultaneously take.

In every case are for The supervision a glass element today several different sensors necessary their procurement and installation costs together over 300 EUR per item. Multifunctional alarm sensors exist so far Not.

Of the general solution is to "fuse" multiple sensors, i.e., multiple functions in one possible integrated miniaturized sensor. From the perspective of the inventor is the "royal road" in the construction of one standardized window handle, which the operator attaches to the frame as a "smart handle" and transmit their alarm and status data wirelessly to a digital one Transmit alarm system.
