Abstract

The electrical installation device-protection system has control logic, analysis and processing units (6,16), where sensors are provided for detecting a movement or change in position of an electrical installation device (1). An alarm signal is generated by the control logic, analysis and processing units by detecting a movement or change in position of the electrical installation device by the sensors. The sensor is formed for detecting the movement or position change of the electrical installation device in a form of a gyro sensor (17).

Description

The invention relates to an electrical installation protection system. A preferred application is given in high-priced installation equipment or sensor / display devices of building system technology.

In the field of electrical installation devices, presence detectors and motion detectors are generally known which detect movements, in particular heat movements, and execute corresponding switching operations. Furthermore, electrical installation devices of building system technology, such as installation switches and display panels with a touch screen are well known.

In many cases, motion detection systems are used to monitor defined spaces and areas in order to prevent such criminal acts or to facilitate the investigation of criminal acts that have been carried out. However, before carrying out a criminal act, such as a theft, it is possible to purposefully disable such a motion detection system by disabling or covering the system / device.

Commonly known presence detectors and motion detectors do not provide adequate protection against intentional misalignment or "out of order" seating in the manner described above, especially when the detector is located outdoors or in a public building and performs a corresponding monitoring and safety function.

Similarly, for example, installed in public buildings high-quality / high-priced electrical installation equipment are vulnerable to theft by an operating unit / functional unit is subtracted from the installed in a flush-mounted box unit base unit / under plaster unit under the influence of violence.

The invention has for its object to provide an optimized electrical installation protection system.

This object is achieved by an electrical installation device protection system of an electrical installation device having at least one control logic / evaluation / processing, wherein a sensor for detecting a movement or change in position of the electrical installation device itself is provided and wherein upon detection of a movement or change in position of the electrical installation device itself by the Sensor an alarm signal using the control logic / evaluation / processing can be generated.

In this context, an electrical installation device is also understood to mean, for example, a camera suitable for wall mounting, as used in the field of safety technology / alarm systems for monitoring a defined environment (for example the entrance area of a house or the access of an industrial installation).

• a wireless and / or wired bus interface for connection to a bus system of building system technology and / or
• a switching output for connection to an alarm device

have, this alarm device can be integrated in the electrical installation device itself or arranged externally.

• eine Anzeigeeinheit und/oder
• Bedienelemente

• in a sixth alternative embodiment of the electrical installation device 1 eliminates the gyrosensor 17;
• in a seventh alternative embodiment of the electrical installation device 1, the contact sensor 18 is omitted;
• in an eighth alternative embodiment of the electrical installation device 1, the light sensor 19 is omitted.

Of course, any further alternative embodiments of the electrical installation device 1 can be realized, which result from a combination of the above-mentioned alternative embodiments, for. B. where both the motion sensor 13, and the gyrosensor 17 and the light sensor 19 omitted, etc.

Furthermore, further embodiments of the electrical installation device 1 can be realized, in which no strict subdivision into a base unit 3 and a functional unit 10 is provided, as already mentioned above. An example of this is a surface-mounted motion detector / presence detector.

In Fig. 2 an embodiment with contact sensor is shown. The base unit 3 of the electrical installation device 1 is installed in a flush-mounted device box 25 mounted in a wall 26. The electrical installation device 1 is completed by the functional unit 10 and a cover frame 20. A contact sensor 18 serves to protect against inadmissible disassembly of the functional unit 10 from the base unit 3.

In Fig. 3 is in addition to the configuration according to FIG. 2 a trained in the form of a switch contact contact sensor. The attached to the base unit 3 contact sensor 18 has two contact springs 23 which are mounted in a housing, with fully assembled electrical installation device 1, a contact pin 22 of the functional unit 10 engages in the contact sensor 18 so that an electrically conductive connection via the contact springs 23rd established. The contact pin 22 is fixedly attached to the functional unit 10, so that this electrically conductive connection is interrupted if the functional unit 10 is removed from the base unit 3. With the help of the control logic / evaluation / processing 6, an alarm signal can be derived from this electro-mechanical configuration.

In Fig. 4 an embodiment is shown with a built-in voltage / data interface contact sensor. In this embodiment, the voltage / data interface 21 between base unit 3 and functional unit 10 has the additional configuration of a typical contact sensor 18 - as in FIG FIG. 3 shown, in addition to or alternatively, the disassembly of the functional unit 10 is determined by the base unit 3 in an electronic manner.

In Fig. 5 a contact sensor designed in the form of a wiper contact is shown. This embodiment can be used if the electrical installation device 1 is designed in the form of a motion detector which has a fastening component suitable for wall mounting. With this attachment component, a head is pivotally connected to a lens optic. In the proposed contact sensor 18, a wiper (sliding contact) 29 is connected to the lens optics. A resistance element 30 is connected to the attachment component. When the lens optic is pivoted relative to the fastening component, the wiper 29 is simultaneously rotated relative to the resistance element 30, so that different resistance values are set, to which different current values or voltage values can be assigned. With the help of the control logic / evaluation / processing 16, the current position of the lens optics can be detected in this way. When the lens optics are twisted impermissibly with respect to the fastening component, the control logic / evaluation / processing 16 can derive an alarm signal from this.

• Eine Verstellung und "Außer Funktionssetzung" eines betrachteten Elektroinstallationsgerätes geht in der Regel mit einer Bewegung einher - abgesehen von einer durch Überspannung verursachten "Außer Funktionssetzung". Ziel des vorgeschlagenen Schutzsystems ist es deshalb, diese Bewegung im Vorfeld der eigentlichen Verstellung und/oder "Außer Funktionssetzung" frühzeitig zu erkennen und zu melden, um weiteren Schaden abzuwenden. Die Detektion ist durch einen Sensor, beispielsweise einen Gyrosensor, einen Lichtsensor, einen Scheiferkontakt, einen mechanischen Kontaktgeber usw. realisiert. Die platz- und kostengünstige Integration eines solchen Sensors in das Elektroinstallationsgerät wird durch die ständige Weiterentwicklung der MEMS "mikro-elektro-mechanische Systeme" technologisch unterstützt. Somit wird beispielsweise bei einem elektronischen Installationsgerät, in dem bereits ein Sensor integriert ist, wie beispielsweise bei einem Bewegungsmelder / Präsenzmelder mit Temperatursensor und Lichtsensor oder bei einem Raumtemperaturregler mit Temperatursensor die Integration von weiteren Sensoren im gleichen Chip begünstigt: "Multi-Sensor-Chips".

Here are some further explanations of the proposed electrical installation protection system:

• An adjustment and "out of action" of a considered electrical installation equipment is usually accompanied by a movement - except for a caused by overvoltage "Auswerkfunktion". The aim of the proposed protection system, therefore, is this movement in advance of the actual Recognition and / or "Out of Function" to recognize and report at an early stage to prevent further damage. The detection is realized by a sensor, for example a gyrosensor, a light sensor, a shifter contact, a mechanical contactor and so on. The space-saving and cost-effective integration of such a sensor in the electrical installation device is technologically supported by the constant development of MEMS "micro-electro-mechanical systems". Thus, for example, in an electronic installation device in which a sensor is already integrated, such as in a motion / presence detector with temperature sensor and light sensor or a room temperature controller with temperature sensor favors the integration of other sensors in the same chip: "multi-sensor chips" ,

For a motion / presence detector or any electronic installation device (a "high-quality" electronic switch or an electronic switch with safety-relevant function), this sensor - see Gyrosensor 17, contact sensor 18, light sensor 19 - can be integrated. The feedback of an undesired / unexpected motion detection by, for example, a gyro sensor 17 or another of the aforementioned sensors can be communicated to the building system via the bus / radio system in the case of an existing bus connection or radio system - see bus interface 7 and thus a preventive alarm, for example trigger visual and / or acoustic signal up to the locking of paths / doors. A similar function is also suitable for non-busable electrical installation equipment 1, which have integrated a corresponding visual and / or acoustic signaling in the electrical installation device 1 itself and / or provide a corresponding switching contact for an external connection and an external alarm device - see switch output 8. Both Solutions can be realized simultaneously (bus system and switching contact).

The detection of a rotary movement of the lens head of a motion / presence detector can be done by a wiper contact, ie an electromechanical potentiometer and / or a light sensor in conjunction with applied or recessed raster mark on the housing.

In an electrical installation device 1 with integrated light sensor 19, for example, after an abrupt darkening of the electrical installation device 1 after evaluation by the control logic / evaluation / processing, a corresponding alarm can be issued.

An equivalent function by means of the contact sensor 18 in the form of a switching contact is for electrical installation equipment 1, which are applied or latched on carrier elements, possible - see the embodiment according to FIG. 3 ,

During commissioning, the proposed protection system is deactivated, i. H. the protective function is activated only after commissioning has been completed.

For all embodiments, it is generally the case that the transmission of the alarm takes place either via the switching output 8 and / or via the bus interface 7.
