Description

The present invention relates to a device for monitoring areas or rooms for the detection of objects located on a monitored area or in a monitored room or of objects entering the monitored area or the monitored room, according to claims 1 to 15.

To protect against unauthorized entry into residential or business properties, monitoring systems are known that can trigger alarm functions and are thus intended to serve as a deterrent. In most cases, either camera monitoring systems, light barrier systems or scanning systems with reflected directional beams are used.

From the EP 0 029 827 B1 a device and a method for room monitoring by means of pulsed directional radiation are known. Here, light pulses from a laser light source are emitted in chronological order in different directions in a site to be monitored at a defined point in time and in a respectively defined azimuth and elevation angle and reflected on an object located in the area. With the help of signal data of the reflected radiation, which are detected by a radiation receiver, unauthorized intrusion can be detected and appropriate warning notices can be provided and, if necessary, countermeasures can be initiated.

Proceeding from this method and this device for room monitoring, the present invention is based on the object of specifying a device for monitoring areas or rooms by means of which an improved display of the monitored area or the monitored room on a display device and a simple selection of partial areas thereof Area or this room are guaranteed for taking special measures. In addition, seamless monitoring is also aimed for in built-up areas.

The above object is achieved by a device according to the features of claim 1.

The device according to the invention for monitoring areas or rooms for detecting objects located on a monitored area or in a monitored room or objects entering the monitored area or the monitored room comprises at least one scanning device, which has a transmitting device for sending measurement signals and a Receiving device for receiving signals reflected from the detected object comprises. The monitored area or the monitored space can be represented in a display device, in particular on a screen, of a data processing system in a two-dimensional image. With the aid of the data processing system, a sub-area of the monitored area or a sub-area of the monitored room can be selected, with the sub-area or sub-area being or can be assigned a predefined action and / or a predefined monitoring function. With the help of the representation, in particular a true-to-scale image, on the display device of the data processing system, the monitored area or the monitored space can be completely overlooked and partial areas or partial areas whose monitoring with the result of a detection of a special feature lead to an action and / or a monitoring function can be selected or defined more precisely. It is possible to define these sub-areas or sub-areas with an accuracy of a few centimeters.

With the scanning device, which can have a laser scanning device, in particular objects close to the ground can be detected. With the aid of such a ground-level scanning, it is possible with as little effort as possible to detect those intruding objects whose intrusion is or can be critical for the monitored area or the monitored space.

The data processing system is or includes, in particular, a computer or a computer-like device, which can also be a mobile device, such as a smartphone, a tablet computer or a notebook. While such a mobile device can be particularly helpful for monitoring at any time, a workstation with a large screen, for example, has advantages when defining sub-areas or sub-areas because of the better clarity and especially with a higher resolution. In this respect, it is useful to choose a particularly suitable data processing device for each purpose.

The two-dimensional image shown or can be shown in the display device can be a two-dimensional floor plan or it can have such a plan. Such a floor plan can be transferred from building plans and / or from cadastral data, for example.

The assigned or assignable action and / or monitoring function can in particular be selected from a predefined configuration menu which can be contained in a program executed or executable by the data processing system or which the program accesses.

In particular, at least one object to be monitored is arranged on the monitored surface or in the monitored space, which object can be represented or represented in the two-dimensional image in the display device, advantageously with all of its contours and outlines. It is advantageous if the object to be monitored is reproduced true to scale in the two-dimensional image. Such an object can be a house whose conceivable access or penetration openings, such as doors or windows, may require special monitoring. The doors or windows themselves can also be or will be defined as objects to be monitored. As a further example, a demarcation device, such as a fence, the overcoming or trespassing of which can be an unauthorized intrusion, is conceivable as the object to be monitored.

However, the object to be monitored does not have to be permanently connected to the monitored area or the monitored space, as in the examples mentioned above. Rather, movable objects, such as a motor vehicle, can also be targets of a monitoring process. In addition, “surveillance” is not only to be understood as the observation of desired objects on the monitored area or in the monitored space, but rather the term “detected object” also encompasses an undesired object, such as a possibly malicious intruder, a possibly desired one and possibly stray visitors on a company premises, or even just a wrongly placed pallet.

• - Alarm durch zugeordnete Geräte oder Einrichtungen;
• - Aktivierung oder Deaktivierung wenigstens einer weiteren Zone;
• - Alarm bei einem erkannten Objekt, insbesondere einem sich in einem ungewöhnlichen Zustand oder an einer ungewöhnlichen Stelle befindlichen Objekt;
• - Anzeige der Verweildauer eines Objekts durch charakteristische

One embodiment of the invention provides that the selected partial area to be monitored or the selected partial area to be monitored, or possibly the object to be monitored, can be assigned to a zone. Through this zone is at least one of the actions

• - Alarm from associated devices or facilities;
• - Activation or deactivation of at least one further zone;
• Alarm in the event of an object being detected, in particular an object in an unusual state or in an unusual location;
• - Display of the residence time of an object through characteristic

Representation, in particular color representation can be triggered.

• - Erkennung einer Bewegung eines Objekts, insbesondere Erkennung der Bewegungsrichtung und/oder der Geschwindigkeit und/oder der Beschleunigung;
• - Erkennung der Anzahl von Objekten, die insbesondere einer definierten Objektgruppe zugeordnet oder zuordenbar sind;
• - Erkennung der Größe eines Objekts;
• - Erkennung eines Objektzustands;
• - Erkennung der Abwesenheit, insbesondere der ungeplanten Abwesenheit eines Objekts;
• - Erkennung der Dauer der Anwesenheit eines Objekts abhängig sein.

The selected or to be selected action can be from one of the events

• Detection of a movement of an object, in particular detection of the direction of movement and / or the speed and / or the acceleration;
• - Recognition of the number of objects that are in particular assigned or can be assigned to a defined object group;
• - detection of the size of an object;
• - detection of an object state;
• - Detection of the absence, in particular the unplanned absence of an object;
• - Detection of the duration of the presence of an object may be dependent.

A dependency on a time of day and / or on a weekday can also be decisive for the assignment to the zone or the setting of a zone. Several periods of time can be combined as a group so that not all individual periods of time are linked individually for the events.

The above-mentioned events can also be made dependent on the object type (animal, human, vehicle, ...).

According to this embodiment, zones can be used to define sub-areas of the monitored area or the monitored space, which are monitored and actions, in particular one of the aforementioned actions, are defined that can be carried out when an event occurs, in particular one of the aforementioned events.

• - ein Objekt/z. B. Mensch betritt, bewegt sich in einer als Sicherheitsbereich eingestuften Zone oder verlässt diese
• - die Bewegungsgeschwindigkeit eines Objekts, beispielsweise einer Person, eine Personenanzahl in einer Zone, Anzahl der Personen mit Bewegungsrichtung von Ort A nach Ort B, kann bzw. können bedeutsam sein
• - Frequentierungen bestimmter Zonen erfassbar
• - Öffnen einer Tür oder eines Fensters eines überwachten Objekts
• - fehlende Objekte: Diebstahl von z. B. Fahrzeugen, abgeholte oder neu abgestellte Paletten.

The following examples can be triggering events:

• - an object / z. B. A person enters, moves in a zone classified as a security area or leaves it
• The speed of movement of an object, for example a person, the number of people in a zone, the number of people moving from location A to location B, can or can be significant
• - Frequencies of certain zones can be recorded
• - Opening a door or window of a monitored object
• - missing objects: theft of z. B. vehicles, collected or newly parked pallets.

• - Alarm durch: eine Sirene oder andere Signalgeber, beispielsweise Ton- oder Lichtsignale, Push-Nachrichten, SMS-Mitteilungen, Anruf, etc.
• - Auswertungen bestimmter Ereignisse z. B. für Statistiken, insbesondere: welche Zonen oder Bereiche werden am meisten genutzt, hierbei kann die Anzeigevorrichtung die unterschiedlichen Frequentierungen der unterschiedlichen Zonen oder Bereiche durch verschiedene Einfärbungen markieren.

Examples of triggerable actions are in particular:

• - Alarm by: a siren or other signaling device, e.g. sound or light signals, push messages, SMS messages, calls, etc.
• - Evaluations of certain events e.g. B. for statistics, in particular: which zones or areas are used most, here the display device can mark the different frequencies of the different zones or areas by different colors.

Another possibility can be that an event in a zone can "create" a new or further zone, i. H. the new or further zone does not have to be defined by the user of the device according to the invention. Rather, this zone can be set up automatically and automatically by the device itself, in particular by appropriate programming. This can be, for example, a newly parked pallet in a monitored zone or a newly parked vehicle that defines a new zone. The newly deposited pallet can be a newly created zone to which an action is assigned, namely monitoring the pallet and triggering an alarm if it is stolen. A zone can preferably be defined according to calendar days and / or times.

A particular embodiment is characterized by a first zone and a second zone to which different priorities can be assigned. Additionally or alternatively, a partial area to be monitored or a partial space to be monitored can be assigned to at least a first and a second zone which have different settings. In particular, at least one action and / or monitoring function that is different from the second zone is assigned to the first zone. This can also be used to define dependencies. For example, a surveillance zone is only activated when a main gate is closed, which can mean that a company with monitored premises is closed.

Measurement signals can preferably be emitted by the transmitting device at time-defined intervals in changing directions, which can include a preferred directional area. The transmission device is preferably designed with all-round radiation, so that the horizontal portion in particular covers an angular range of 360 °. In this embodiment, the received reflected signals can be transmitted to display points or display surfaces and can be displayed in the display device in the two-dimensional image, in particular the two-dimensional floor plan, according to the properties of the detected object. These object properties can be or include the position and / or the course of movement and / or the outline of the object.

The detected reflected signals can in particular be assigned to one or more defined object groups. In this case, an object group can be transferred to an object representation for displaying the detected object in the two-dimensional image and / or can be assigned to at least one action and / or one monitoring function. For every measurement result, an attempt can be made to divide it into a defined object. For example, an algorithm of an evaluation program tries to classify recorded measurement results or objects into walls, people, animals, vehicles, pallets, etc. Environmental influences can also be helpful in the classification, for example to distinguish solid and rigid objects from flexible ones. Objects moving around a center point or a central position, for example moving in an oscillating manner, can be defined as leaf movements in the wind, while a wall is generally immobile in any weather.

According to a special embodiment, an assignment of the detected reflected signals to or their division into permanently present objects or into objects that occur at times is provided. Permanent objects are part of the monitored area or the monitored space. They include in particular the object to be monitored and / or can be assigned or assignable to an action and / or a monitoring function. Example of this are the object types: door, gate, roller shutter, window, etc. Here the system can recognize whether a roller shutter or a door is open or closed, i.e. it can recognize a status / event of the object. An action can be linked to the state / event of the object, such as switching on a light.

In contrast, objects that appear from time to time are particularly flexible. However, such objects that occur only temporarily can also be made the subject of a zone and / or an action or monitoring function, but this action or monitoring function usually differs from that of a permanent object. For example, when a vehicle is recognized, a zone around the parked car can be automatically activated and an action can be assigned when an event occurs.

A special embodiment of the device according to the invention provides that each object within the measurements can be assessed for stability by means of a point system or the like. The more points an object receives, for example, the slower a reaction to changes in measurement results can be. An example of this is a motor vehicle that is parked in front of a wall, with the result that the parts of the wall covered by the motor vehicle are no longer from the Scanning device are detectable. Even so, the wall is still displayed in the display device. Moving or moving objects with a lower evaluation score, in particular a lower score, on the other hand, disappear in a significantly shorter time from the display device, in particular from the mapped plan view.

According to a further embodiment, an automatic object marking of different object types is provided, taking into account the stability of the measurement points or taking into account movement patterns. For example, the following object types are provided: New measuring point, measuring point which has been recognized for a long time but is not stable, wall-like measuring point, wall or very stable measuring point, hedge, human, animal, vehicle, etc. To identify the recognized object types, colors, Tags, pictograms, symbols, hatching or the like are provided. For example, doors, gates and windows can be graphically displayed in the aerial photograph. In addition to the possibility of an automatic assignment of the object types, a manual assignment of the object types to the measuring points is also possible or provided after execution. Vehicles have a very distinctive shape. Likewise, pedestrians walk very differently from animals. After execution, these recorded objects are assigned either manually or automatically from a list / database of stored object types. If such a database is part of the device, classified objects are already stored there. According to a further variant, the device has a neural network or is connected to it, so that the object assignment improves over time.
In principle, the system recognizes walls, people, cars, animals ... independently after a learning phase. In addition, object types: gate, door ... but also manually in the 2D floor plan can be marked as gate or door. The system would thus quickly recognize an open door. In contrast to an undefined door, it would take several minutes or hours for the system to display / mark the “open door” in the 2D floor plan.

The system constantly monitors all objects. Each object is given a unique ID and is cataloged in the system. The following parameters are taken into account: object size (area), object diameter, object shape, object speed, object dwell time within the zone, object dwell time in the entire detection area, object activity / mobility (direction of movement, acceleration), movement path within the detection area.

With these parameters and possibly other details, the object is also divided into an object type: wall, human, animal (large), animal (small), car, car with trailer, bicycle, stroller. These parameters can also be defined in a defined zone as a "trigger".
This means that a zone does not necessarily have to be set to "activated" if only a small object enters the zone. This setting can be made in the zone. Thus, a zone can only react to a car or an object of a certain size or shape.

According to a further embodiment, the device stores unusual objects in a history log. A variant of the invention also provides for unusual routes, events or objects to be presented to the user. Here the system should recognize these "irregular events" independently.

The received reflected signals and / or their transmission in display points or display areas can preferably be assigned to a site plan or an aerial view of the area to be monitored or of the area to be monitored. It is particularly advantageous if the site plan or the aerial photograph can be superimposed or superimposed on the two-dimensional image. This makes it easier for the user or observer of the display device to orientate themselves in the representation of the monitored area or the monitored space.

A sub-area or sub-area to be monitored, in particular the zone to which the sub-area or sub-area is assigned, can be defined by selecting an assigned area in the two-dimensional image on the display device. The selection or definition is preferably carried out by means of a marking, in particular by means of a colored marking, on the display device, so that this also results in a highlighting. With the help of the superimposition of the floor plan with an aerial photograph or a particularly detailed site plan, the sub-area or sub-area to be monitored can be defined very precisely, in particular with a precision of one to six centimeters.

A particularly user-friendly embodiment of the device according to the invention provides that the partial area to be monitored or the partial space to be monitored, in particular the zone, can be defined with the aid of graphics processing aids via an input device. These tools can be designed virtually. Any known conventional type, such as a computer mouse or an input pen, is conceivable as an input device. The input device can be used to generate a screen representation in the form of a virtual brush or enlarge a zone or a virtual eraser to reduce or delete a defined or fixed-size zone.

It can also be provided that at least a first scanning device and a second scanning device and the display points or display areas formed from received signals of the first scanning device, compared to the display points or display areas formed from received signals of the second scanning device, can be represented differently. As an alternative, a different identifier or coding, in particular color coding, is also possible. In this respect, an assignment of the display points or display areas to the respective scanning device, that is to say an indication of which display points or display areas were generated by which scanning device, can be recognized. It can therefore be determined, for example, which scanning device has produced or produced a specific movement track of a moving object in the display device.

In order to conceal the function of the device as a monitoring means, the scanning device can be installed in a housing which is used in an ordinary device or in an ordinary device, which device or device is common at the place of use, but is used for a different purpose than that of a monitoring facility. Since a company site or a private residential area are essential areas of application of the device according to the invention, its installation in a housing of a lamp device, in particular a path or terrace lighting device, is particularly favorable and inconspicuous.

This device according to the invention for monitoring areas or rooms, by means of which objects located on a monitored area or in a monitored room or objects entering the monitored area or the monitored room are detected, provides that a transmitting device of a scanning device has measurement signals defined in time Sends out distances in changing directions and a receiving device receives at least one signal reflected from a detected object. The transmitting device emits measurement signals, the horizontal portion of which covers a predetermined angular range, which is in particular 360 °, so that all-round monitoring is made possible by the scanning device. The received reflected signals are transmitted to display points or display surfaces and displayed in a display device in a two-dimensional image according to the properties of the detected object. This method can be operated in particular with or in one of the facilities described above.

The display device can be part of a data processing device with which the method can be operated or which supports the method. Such a data processing system is or includes, in particular, a computer or a computer-like device, which can also be a mobile device, such as a smartphone, a tablet computer or a notebook. The display device is in particular a screen of the data processing device. With the scanning device, which can have a laser scanning device, in particular objects close to the ground can be detected.

The two-dimensional image shown or can be shown in the display device can be a two-dimensional floor plan of the monitored area or it can have one.

The position of the detected object and / or its course of movement and / or its silhouette, that is to say its outlines, is preferably represented.

The method can provide that a signal received by the receiving device is assigned to an object representation or an object group.

Received signal data are preferably assigned to a coordinate system, in particular a Cartesian coordinate system or a polar coordinate system, or a vector data model and transmitted to a central processing unit. It is advantageous if repetitive data is only transmitted once. These measures can help to ensure that the amount of data transferred remains within a manageable framework, which on the one hand cannot contribute to a cost-effective system, on the other hand it allows the measurement speed and thus the better traceability of traces of movement of moving objects.

It can also be provided that signal data of the reflected signal from a first scanning device and a second scanning device are transmitted to the central processing unit and, in order to keep the transferred data volume as low as possible, overlapping signal data from the first and second scanning devices only by one of these two Scanning devices are transmitted. The scanning device which is arranged closest to the detected object or recognizes a movement of the detected object more clearly is used for this purpose.

The transmitted data volume can also be kept low if objects are suppressed during the transmission which only occur due to special environmental conditions, in particular special weather conditions or influences. In the same way, movements of an otherwise stationary object, for example a tree, are advantageously suppressed, which only occur due to the aforementioned special influences or conditions, that is to say in particular movements due to wind.

The above object is also achieved by a device according to the features of claim 18.

Such a device for monitoring areas or rooms for the detection of objects located on a monitored area or in a monitored room or of objects entering the monitored area or the monitored room according to the invention has at least one scanning device, which has a transmitting device for transmitting a Measurement signal and a receiving device for receiving a signal reflected from the detected object comprises. The transmitting device can emit measurement signals at defined time intervals in changing directions, the horizontal portion of which covers a defined angular range, which is in particular 360 °. At least one first and one second scanning device are provided which are arranged at a distance from one another and whose monitored surfaces or whose monitored spaces at least partially overlap. In this way, the monitoring area can be enlarged. In addition, with a suitable placement, areas can be “viewed” by a second scanning device which lie in a shadow area of the first scanning device. With several scanning devices it is also possible to capture objects from all sides. With the scanning device, which can have a laser scanning device, in particular objects close to the ground can be detected. The device just shown further develops in particular one of the devices described above and / or can be operated or connected to a method according to one of the configurations shown above.

The device according to the invention can have a central processing unit to which the at least first scanning device and second scanning device are connected. The integration in a common network of the central processing unit and the two scanning devices is favorable.

Finally, a particularly preferred embodiment of the invention provides that the first and second scanning devices can be aligned with one another. For this purpose, an automatically running alignment mode is preferably used. The two scanning devices are aligned with one another in particular by each of the two scanning devices scanning a common reference point or reference object. An object that is cross-shaped in horizontal cross-section or generally a reference object with straight surfaces and a 90 degree angle has proven to be advantageous, with the aid of which several scanning devices / lasers can be aligned very easily, which "see" the cross. This is done automatically with the help of an algorithm or can be done manually. Additionally or alternatively, the two scanning devices can be aligned with one another by scanning one another. The reference object preferably also has markings that can be easily recognized from the air. According to one embodiment, the reference object has a circle that is visible from a bird's eye view, that is to say formed in the horizontal plane, with a cross therein. An aerial photograph of the area to be monitored can then be superimposed automatically or manually with the values of the scanning device (s) with the aid of an algorithm.

The location of the scanning device is preferably represented in the 2D floor plan by a symbol, for example a circle. The symbol also preferably shows the temperature and a time stamp of the last feedback. It is preferably possible to shift and rotate the representation of the measured values of the individual scanning device (s) in the X and Y directions. So that manual correction is possible. The measurement results are preferably displayed in a different color or a different pattern depending on the respective scanning device. If you do not use an automatic setting and choose manual alignment, you only have to adjust the X and Y alignment of the scanning device / laser according to the position on the aerial photo. All changes are made in real time. Thus the floor plan changes immediately. It is even easier if a reference object is used as described above. Then you only have to correct the position X and Y of the scanning devices / lasers so far that the measuring points of the respective scanning devices (e.g. different colors) are exactly on the reference object.

The described and further features are in particular also the subject of the attached patent claims. In addition, it is pointed out that all features that are presented as device features in connection with one of the described devices are also understood as method features in connection with a method that can be used in the respective device should be. The same applies to method features which can also be connected as device features to one of the described devices.

The invention is explained in more detail below with reference to the drawings of an exemplary embodiment. Show:

1 shows a basic representation of a laser scanner 1 , which serves as a scanning device part of an object protection device. With the help of this property protection device, a site can be monitored, for example a company site or a private site, possibly with a house with a surrounding garden.

The laser scanner 1 according to 1 is a 360 ° scanner, which, as indicated at 3, around its vertical swivel base 5 is rotatable. In order to achieve particularly frequent scanning to detect faster movements of an object on the monitored area, the laser scanner runs through 1 a full circle several times per minute. A laser transmitter transmits during its rotation 7th standing on a rotating platform 9 is applied, at discrete time intervals in radial, horizontal direction a measurement signal 11 in a horizontal direction into the monitored area. If the transmitted measurement signal hits an object in the area, the measurement signal is at least partially reflected and thereby forms a reflected signal which, after a corresponding transit time, the laser scanner 1 reached in the opposite direction to the measuring signal. This signal transit time depends on the distance of the detected object from the laser scanner 1 dependent. In addition, the direction of the transmitted measurement signal can be detected with the aid of angle sensors (not shown), so that the position of the detected object can be determined with known parameters of direction and transit time. A receiving means, for example an infrared sensor, is used to detect the reflected signal 13 , on the rotating platform 9 arranged.

So that with the principle representation according to 1 shown laser scanners 1 On the one hand, it is protected from environmental influences, on the other hand, it is not conspicuous in the monitored area, for example to work undercover, is the laser scanner 1 in a housing of ground level path lighting 15th which can also be used as patio lighting. This path lighting 15th is according to 2 on the edge of a path 17th belonging to the monitored area. The path lighting 15th thus has in addition to its usual task, namely at dark times of the day for at least sufficient light conditions on the way 17th to take care of another task, a housing and a concealed work environment for the laser scanner 1 to deliver. The transparent or semitransparent window used for the emission of light is used for unhindered transmission of the measurement signals and reception of the reflected signals 19th the path lighting 15th particularly well suited. The path lighting 15th or the built-in laser scanner 1 has a heater (not shown) in order to ensure perfect functioning even in the winter months through operating temperatures that remain almost the same or at least not too low, for example to prevent the window from misting up 19th to prevent. A cover 21st prevents solar radiation, dust formation and water droplets, which could possibly falsify measurement results. In addition to a suitable seal, a drip guard (not shown) with a drip edge, which can be attached around the edge of the circular cover and directed downwards, prevents water running into the center of the cover with the risk of penetrating into the interior of the path lighting 15th . In addition, water stains on the optics of the laser are effectively prevented in this way. Finally includes the cover 21st another surface that has a solar cell-like structure and thus resembles that of a solar panel, creating a further measure, the function of path lighting 15th as a mount for a laser scanner 1 not to reveal.

3 shows the path lighting 15th at a different location on the same site as at 2 . In order to obtain a larger surveillance area and in particular also one for one in a first path lighting 15th integrated first laser scanner 1 hidden area of the curved path 17th Being able to monitor as well is one in a second path lighting 15 ' integrated second laser scanner 1 at a distance from the first path lighting 15th Installed. 3 shows the monitored area at a darker evening or night when the pathway lighting is on 15th , 15 ' fulfill their further task of donating light. Also shows 3 even vehicles parked on the area to be monitored 23 , which can also be target objects of the surveillance, and a possibly unauthorized removal of a motor vehicle 23 can for example lead to an alarm signal.

Again 3 It can also be seen that not only are measurement signals sent in all directions of a 360 ° rotation, 360 ° LED lighting is also provided. This LED lighting can also be used to display the status of a control and computing unit of the laser scanner 1 such as starting or booting, connection display, alarm signals, etc. Each of the two in the path lights 15th , 15 ' integrated laser scanner 1 has such a control and computing unit. These are not only connected to one another via a wireless network, but also to a central processing unit for the purpose of exchanging data. For this purpose, the path lights have a unique hardware ID, a unique IP address in the network and, if necessary, parameters to get the same scale for different device types. In general, of course, a wired network structure is also possible, but much more complex due to the concealed laying of cables. The central processing unit receives the from the two (or more) laser scanners 1 transmitted signal data and evaluates the information received with regard to detected objects in the monitored area.

In order to keep the amount of data to be transferred as low as possible, the lasers only send signal data that is repeated within a defined period of time. Overlapping signal data from multiple laser scanners 1 that, for example, scan the same object, but possibly from two different directions, are also subtracted before the transmission and therefore not transmitted. Conveniently, only the signal information from the laser scanner is used here 1 that is closest to the captured object. Alternatively, possibly also cumulatively, the laser scanner can also be used 1 be used for transmission, which recognizes this movement best in the event of a movement of the detected object. In order to be able to guarantee the transmission of only the most suitable signal in each case, the control and computing units of the two laser scanners 1 connected to one another by means of a corresponding evaluation software.

With the laser scanners 1 according to 3 These are monitoring devices with scanning close to the ground, as these laser scanners 1 in path lighting close to the ground 15th , 15 ' are built in. In addition, there is only one scanning in the horizontal direction, so it is only scanned over an area. This is sufficient, however, since it detects intruders who can be critical for the terrain or objects located on it.

4th represents a screen display of a monitored area, in the present example a residential and garden property with a house 25th , in a top view. The plot of land is on the screen 27 with the help of an aerial photograph, for example created by a controlled flying object, preferably a drone. Instead of the aerial photograph, a construction plan drawing or a cadastral representation can be used, but an aerial photograph is usually more up-to-date and closer to reality. On the aerial photo are also one of the apartment building 25th adjacent garage 29 and vehicles parked at the house 23 recognizable.

Using the to the screen 27 Monitoring zones belonging to the control and computing unit, preferably a computer (not shown), can now be set up. In the example according to 4th became a property line in the form of a fence 31 marked by the user or the person setting up the monitoring system. An unauthorized crossing of this fence 31 can possibly be an alarm-triggering event. There is also a door 33 and two windows 35 leading to a terrace 37 show as possible penetration openings into the residential building 25th marked and specifically defined as zones.

Instead of marking the aforementioned objects or zones 31-35 by the user, these objects can also result from scanning by at least one laser scanner 1 and subsequent evaluation or assignment by the associated control and processing unit or the central computer or computer.

5 shows the screen display analogous to 4th with the same monitored area .. The one with this one 5 The screen settings shown also have a selection window 39 for setting up an additional scanning device, i.e. a further laser scanner 1 , on. With a in the selection window 39 available selection field 41 For example, one of these laser scanners 1 set the assigned color with which this device 1 detectable area, in particular its border 43 , is color-coded. In addition, the location of the scanning direction can be adapted with the help of the selection field “Position x / y) and, for example, it can be shifted to the location of the scanning direction to be recognized in the photo. The position correlating with the sampled values, which can be shifted with the aid of the selection field, is preferably characterized by, for example, a point so that this point can be moved over the location recognizable on the photo. With the help of the "Orientation (degree)" selection field, the scanned values of the scanning device can be rotated around the location of the scanning device so that the displayed markings (e.g. corner of the house or the above-mentioned reference object) are in the corresponding positions recognizable in the photo. With the help of the “Scale” selection field, it can also be ensured that the displayed positions measured by the scanning device have the same scale as the photo.

With 6 shows another step in the monitoring system setup process. Here represents 6 same view of the site as 5 but with a next selection window 39 ' for the definition of a zone 45 . In the example shown, a selection field was initially used 41 ' this selection window 39 ' a color coding for the zone to be defined 45 set. Then, with the help of virtual drawing means known from standard ^programs such as Microsoft® Paint, for example a virtual brush, which can be controlled by the pointer of the PC mouse and which can preferably be set in different sizes, that area was entered in the plan view that corresponds to the area of the zone should represent. Another selection field 41 '' allows the zone 45 to give a name. Zones that have already been defined are preferably changeable, for example changeable in size, which can be made possible by a virtual eraser.

Also with 7th the view of the area to be monitored is shown, but again with the zoom setting according to 4th . You can see next to the fence described above 31 several drawn and thus defined zones 45a-45e by multiple laser scanners 1 are scanned and to which actions or monitoring functions not described here are assigned.

Finally with 8th the view of a display 47 a smartphone intended for monitoring and possibly receiving an alarm. Before or during the display according to 8th the movement of an unspecified object, possibly a resident or a desired or uninvited visitor to the site, took place or is taking place, which movement occurs by means of a movement track in the form of a comet's tail 49 is shown. The darkest track point represents the current position of the moving object and earlier positions that have already been left behind in the course of the movement gradually fade. On the basis of the information obtained with this display representation, the viewer can now decide whether it is an alarm condition and whether an action must be triggered.

9 a principle illustration of the programmability of a first action in which the light in the entrance area of a house is switched on. First, the operator selects or creates a specific action, here the “light on” action. He has the possibility to activate or deactivate the status of this action and to determine the name of the action. This is followed by a combination of conditions with the help of Boolean operators, which determine when a certain action is to be carried out. In this case, switch on the light in the entrance area. As shown here, the light is switched on if the value of the zone "Entrance area" is 1 and if the last update was more than 5 seconds ago.

10 shows the definition of a further action, namely the "Alarm 1" action. Under the condition that the value of the zone "alarm zone" is 1, the action activates the alarm device and the emergency call. However, the alarm is only active between 11 p.m. and 4 a.m.

In the 9 and 10 The zones called “entrance area” and “alarm zone” were previously marked / defined on the screen using a virtual brush.
