A key feature is that the presence sensor R includes a radar sensor, which covers a detection area EB within the room that can be defined by means of two adjustment devices EM1 and EM2, and that a non-detection area NB lies between the detection area EB and the radar sensor.

Description

[0001] The invention relates to an installation device for building installation technology comprising a presence sensor for detecting a person within a room, an actuating element, a control and evaluation unit, a connection to a power supply and a display.

[0002] Presence sensors are becoming increasingly popular, for example for switching lights: A pyroelectric sensor, such as a motion detector, is installed on a ceiling or wall to detect a person within the living space. As soon as it detects a person, a light (controllable via an installation device) is then activated.

[0003] A disadvantage is that pyroelectric sensors are highly temperature-dependent and do not reliably detect, especially at high ambient temperatures. Furthermore, the detection range itself is also highly temperature-dependent, meaning that specific actions, such as switching on a desk lamp when sitting down at a table, cannot be reliably implemented, as the boundaries of the detection range are both too imprecise in themselves and too imprecise to adjust.

[0004] The sensitivity of motion detection in classic motion detectors that utilize one or more pyroelectric sensors is a measure of the detection range; thus, the detection area.

[0005] This can happen when... partner.gira.de / data3 / 20403210.pdfUnlike conventional motion detectors, the pyroelectric sensors are parameterized separately via software (also called ETS) using a computer, and can also be modified on-site after commissioning. The motion detector has an adjustment mechanism that allows the parameterized sensitivity setting of all pyroelectric sensors to be changed. The sensitivity can be decreased or increased by a maximum of one step using this mechanism. However, parameterization via computer is often perceived as cumbersome and / or inconvenient. Furthermore, the global setting of the pyroelectric sensor's sensitivity for motion detection, as a measure of the detection range, is problematic because it does not define an explicit detection range, but merely a sensitivity level. Defining a specific, spatially arbitrary area is therefore not possible.

[0006] This is one of the reasons why such motion detectors are regularly supplied with plastic caps that are placed over the pyroelectric sensor to artificially restrict the detection range by blocking the sensor, thus getting closer to the desired area of ​​detection. However, this solution is also not sufficiently accurate and is often considered aesthetically unappealing.

[0007] Based on this discussed prior art, the invention therefore aims to create a building installation device with a presence sensor that, on the one hand, has a precise, sharply defined, and, as far as possible, temperature-independent detection range that can be spatially arbitrary, and on the other hand, offers a simple setting option for the detection range, particularly during commissioning. This problem is solved by a building installation device system, a building installation device comprising a presence sensor for detecting a person within a room, a control and evaluation unit, a connection to a power supply, and a display, wherein the presence sensor includes a radar sensor, wherein the radar sensor covers a detection range in the room that can be defined by means of two adjustment means, and wherein there is a non-detection area between the detection range and the radar sensor.

[0008] The core concept of the invention is that, in the building installation device according to the invention, which incorporates a presence sensor for detecting a person within a room, a non-detection zone exists between the detection area and the radar sensor. This cleverly utilizes the precision of the radar sensor provided according to the invention to sharply define the detection area between the detected person and the radar sensor or the installation device, thus making it possible, for example, to distinguish between a person sitting down at a table and simply walking past the installation device. This is achieved in a completely unobtrusive manner, in particular without the need for a cover to block the sensor, as is regularly the case with known pyroelectric sensors.

[0009] The core idea of ​​the invention, on the other hand, is that the radar sensor covers a detection area in space that can be defined by means of two adjustment devices, so that any spatially arbitrary area can be detected or not detected. The two adjustment devices according to the invention also eliminate the need to use a computer to adjust the detection area, particularly during the commissioning of the installation device according to the invention for building installation technology. This also advantageously eliminates the need to connect a computer to the installation device.The inventive method of defining the detection area in space by means of two adjustment means is not to be confused with the prior art method of adjusting the sensor sensitivity of a pyroelectric sensor, since sensor sensitivity is adjusted globally and indiscriminately, whereas the inventive method involves a sharp demarcation of a detection area from a non-detection area, with a non-detection area lying between the detection area and the radar sensor. For this purpose, the installation device according to the invention has two adjustment means, for example, to set the length and width of a detection area.In this respect, the number of adjustment means (at least two according to the invention) indirectly illustrates the fact that adjusting the detection range is not simply a matter of varying the sensitivity of the pyroelectric sensor, for which one adjustment means is usually sufficient. To assist in adjusting the detection range and / or non-detection range, the installation device according to the invention has a display.

[0010] In a particularly preferred embodiment of the installation device according to the invention, this device is a light switch / light push button or a blind switch / blind push button. In this embodiment, the radar sensor is invisibly arranged behind an actuating element, and the need for a separate installation with a connection to a power supply is eliminated. Furthermore, such an installation device according to the invention has a height of approximately 1.1 m above the floor, so that – unlike, for example, a socket near the floor – a good overview of the detected area is provided, thus advantageously improving the precision and reliability of the detection.

[0011] According to a preferred embodiment of the installation device according to the invention, the area of ​​the detection zone is movable by means of the adjusting means. This offers the advantage that the initially defined area of ​​the detection zone can then be moved to the desired position by means of the adjusting means. For example, a table moved in the room and detected by the installation device according to the invention can be mapped in such a way that the detection zone is not redefined, but merely moved by means of the adjusting means. This effectively increases flexibility and ease of use.

[0012] In a particularly preferred embodiment of the installation device according to the invention, the two adjustment means explicitly define a non-detection area in addition to the detection area, so that certain areas can be explicitly excluded and the precision of a sharp demarcation is further improved. This is achieved, for example, by the installation device according to the invention detecting a person in the non-detection area, but the control and evaluation unit ensuring that this is not interpreted as a detection in the detection area, for example, if only a small body part, such as a hand, enters the detection area for a few seconds or fractions of a second, while the main part of the body is clearly and permanently located in the non-detection area.

[0013] In a further embodiment of the installation device according to the invention, the detection range and / or the non-detection range is stored in a non-volatile memory of the control and evaluation unit of the installation device. This offers the advantage that stored configurations are retained in the event of a power failure.

[0014] In a particularly favored embodiment of the installation device according to the invention, which is especially useful for setting up its own automation or scenes, the device is connected to an actuator, in particular an actuator for controlling a lighting device, a blind, a room thermostat and / or an electrical device – depending on the detection of a person within a room. Preferably, the detection area is completely enclosed by a non-detection area, thus maximizing detection reliability.

[0015] According to a further embodiment of the installation device according to the invention, the detection area includes a permanent occupancy area, in particular a table, a seat, or a bed. This ensures its use in particularly relevant and attractive detection areas.

[0016] According to a further embodiment of the installation device according to the invention, the detection range is height-adjustable by means of an adjustment device. This ensures, for example, that animals walking on the ground, but where a detection range at a certain height above the ground is desired, for example at least 70 cm, are systematically ignored.

[0017] According to a further embodiment of the installation device according to the invention, the setting means are designed as a digital absolute encoder (advantage: small installation space) or potentiometer (advantage: cost-effective).

[0018] The invention is described below with reference to the accompanying figures and various exemplary embodiments. The figures show: Fig. 1 :a schematic side view of an installation device according to the invention, wherein a non-detection area lies between the detection area and the radar sensor, and Fig. 2: a schematic side view of an installation device according to the invention, wherein the detection area is completely enclosed by a non-detection area.

[0019] In the various figures, identical parts are always marked with the same reference symbols and are therefore usually only named or mentioned once.

[0020] Figure 1Figure 1 shows an installation device I according to the invention comprising a presence sensor R for detecting a person P within a room, a control and evaluation unit MC, a connection to a power supply, and an indicator LED. In the present case, the installation device I according to the invention is designed as a light switch S having an actuating element B in a junction box D installed in a wall W.

[0021] A particular advantage is that the presence sensor R comprises a radar sensor, wherein the radar sensor covers a detection area EB in the room that can be easily extended by means of two adjustment devices EM1, EM2, which can be operated simply with a finger F and without technical aids, and that a non-detection area NB lies between the detection area EB and the radar sensor R. In this embodiment, the detection area EB is designed as a rectangle with width Z and length Y, wherein the non-detection area NB between the detection area EB and the radar sensor has a length X and also a width Z. This makes it possible to precisely ignore the mere passing of person P by the radar sensor in the non-detection area NB arranged between the detection area EB and the radar sensor, but only the entry into the detection area EB is considered as detection of person P.

[0022] Figure 2Figure 1 shows another installation device I according to the invention, wherein the detection area EB is completely enclosed by a non-detection area NB. Such a non-detection area NB can also be explicitly set by the adjusting means EM1, EM2, which are implemented as potentiometers in a particularly cost-effective version. Preferably, the detection area EB is a permanent (for example, a person remaining in the detection area EB for more than 30 seconds) area of ​​presence, in particular a table, a seat, or a bed.

[0023] The invention is described with reference to exemplary embodiments. Without departing from the scope of the applicable claims, numerous further possibilities for implementation would arise for a person skilled in the art, without the need to explain these in detail within the scope of these explanations.
