Description

Background of the Invention

The invention relates to a reporting system for reporting dangers in a building interior, the reporting system having several, and the reporting units each having a position determination means and a detector.

The invention also relates to a method for setting up a reporting system for reporting dangers in a building interior.

the end US 2017/0088261 A1 a system for locating people outside of buildings with unmanned aerial vehicles has become known. The position of the aircraft is monitored and controlled via transmission masts. However, this system cannot be used inside a building.

In U.S. 2010/0073234 A1 a system for warning of danger is described in combination with localization units. The localization units are connected to the already installed detectors and are used to localize people and objects.

Conventional systems for reporting dangers inside buildings, for example when a fire breaks out, have signaling units with detectors for detecting said dangers. The detectors are distributed throughout the interior of the building.

However, the exact positions of the reporting units in the interior of the building have to be transferred to a coordinate system of the reporting system in a complex manner. The installation of the detectors is therefore associated with great effort and considerable costs

In order to be able to determine the positions of the reporting units within the building with sufficient accuracy, some reporting systems therefore have reporting units with a position determination means. The position determination means serves to determine the position of the signaling unit in the building.

Irrespective of this, the commissioning and integration of such reporting units in a reporting system must still be carried out by specialists, which entails considerable expenditure.

object of the invention

It is an object of the invention to simplify the integration of reporting units into a reporting system.

Description of the invention

This object is achieved according to the invention by a reporting system having the features specified in patent claim 1 and by methods according to patent claims 7 and 10.

Reporting system according to the invention

In other words, the object is achieved by a reporting system of the type mentioned at the outset, which is characterized in that the reporting system has a control unit for automatically calibrating at least one of the reporting units.

The reporting system is used to report dangers in a building interior. The reporting system is preferably also designed to recognize the dangers. In other words, the reporting system can pass on information about a hazard that it has recognized or otherwise communicated to it. This makes it possible to react appropriately to the danger.

The reporting system has several reporting units. The position of a signaling unit to be measured can be determined by determining the distances between the (already measured) signaling units of the signaling system and the signaling unit to be measured.

The distance between two reporting units is preferably determined by the two reporting units. For example, the distance can be determined by determining the time difference between the time a signal is sent and the time a response to the signal arrives (if the signal propagation speed is known). Furthermore, for example, the distance can be determined by calculating the difference between the time of transmission of a signal from one reporting unit and the time of arrival of the signal at the other reporting unit, with the reporting units transmitting the time of transmission or the time of arrival.

The at least two reporting units are arranged within communication range of one another and within communication range of the reporting unit to be measured.

The reporting units each have a detector and a position determination means. This enables the provision of a functional capable unit with which the reporting system can be expanded without additional components.

The detector is designed to recognize hazards and/or to receive an indication of a hazard. The detector is preferably designed to detect heat sources and/or gases. In order to receive the information about the danger, the detector can have an input device, for example a switch or button. Basically, a hazard in this context means an impairment of the health of the people and/or animals located in the building or the objects and machines located in the building or the building itself. The detector can therefore be designed in particular to detect liquids, poisons and/or radiation.

The position determination means is designed to communicate with other position determination means. The position determination means is preferably designed as a transmitting and/or receiving unit. This is advantageous with regard to the exchange of information between the position determination units.

The reporting system preferably has at least ten, particularly preferably at least one hundred, reporting units. This increases the accuracy of the position determination by the position determination units and enables more accurate calibration of further reporting units. Furthermore, this allows a larger building interior to be monitored and/or the monitoring density of the building interior to be increased. Provision can be made here for the monitoring density to be increased in some areas by arranging more reporting units per area or volume of the building interior in the first partial areas than in the second partial areas.

More preferably, the signaling unit is designed for immediate (direct) and/or indirect (indirect) communication via other signaling units with the other signaling units in the interior of the building. In this way, a communication network can be formed particularly advantageously between all reporting units of the reporting system. In other words, indirect communication between two reporting units that are not in the immediate communication range of one another can take place via further reporting units of the reporting system.

For example, a reporting unit to be measured can be arranged in the interior of the building within communication range of two reporting units of the reporting system—which are preferably themselves within communication range of one another. As a result, a position can be determined directly by the three reporting units involved.

Furthermore, for example, the signaling unit to be measured can be arranged in direct communication range to at least two signaling units of the signaling system, which for their part are only in indirect communication range to one another. In this case, a position can be determined via the communication network formed by the reporting units of the reporting system.

Alternatively or additionally, provision can be made for the reporting system to be provided with additional information about the arrangement of the reporting units in the reporting system. For example, the reporting system can be provided with the information that all reporting units are arranged at the same height and/or with the same alignment in the interior of the building. This simplifies the determination of the position of a signaling unit to be measured, in particular in building interiors that are essentially one-dimensional or two-dimensional. One-dimensional building interiors have a dominant extension direction (e.g. X direction), whereby the remaining extension directions (e.g. Y and Z direction) are functionally negligible, for example long corridors. In this case, the position determination is reduced to a position in the direction of the alignment of the reporting unit in the dominant direction of extent, which can be carried out by just one reporting unit of the reporting system. For two-dimensional building interiors, an extension in a height direction can be negligible or functionally irrelevant. The additional information can reduce the number of reporting units required in these areas.

Alternatively or additionally, it can be provided that at least one reporting unit has a further, in particular two further, position determination means. In addition to determining the distance between the signaling units, this also enables the relative position of the signaling units to be determined in relation to one another. In other words, an alignment of the reporting units with one another can be determined. This allows the position determination to be further improved.

The reporting system has a control unit. The positions of the reporting units of the reporting system are stored in the control unit, for example on a data carrier. Furthermore, the control unit can have a human-machine interface for inputting and outputting information and instructions. This allows the operation and monitoring of the reporting system is particularly easy.

The control unit can be arranged outside the interior of the building, in particular in a danger control center. This simplifies access to the control unit even in the event of danger or if the interior of the building cannot be entered safely.

In special cases it can be provided that the control unit is arranged inside the building. In this case, the control unit itself is preferably designed as a signaling unit. This enables a particularly efficient use of the control unit.

The control unit is designed to carry out the automatic calibration process for the signaling unit to be calibrated. The automatic calibration can be triggered manually and/or automatically. Automatic triggering can take place when predetermined triggering criteria are met, for example after a predetermined time interval has elapsed. As a result, the installation effort to be made can be further reduced.

The interior of the building can have several sub-rooms/floors, etc. The interior of the building is typically enclosed on all sides. In particular, the interior of the building can be a coherent covered space. In other words, all areas of the building interior can be located under the canopy.

In a preferred embodiment, the reporting system has at least one means of identification, preferably several means of identification. In this case, the position of the means of identification can be determined in the interior of the building by the reporting system. In other words, the means of identification can be located inside the building. For this purpose, the means of identification can communicate with the reporting units.

The identification means is preferably designed to be arranged on an object, particularly preferably on an ID card and/or on a container and/or on a person. This allows the object, for example the person, to be located in a simple manner using the identification means. Advantageously, the reporting system is also used to determine the position of an object or to determine where the object is located in the building.

Preferably, the identification means has a holding means that enables a captive arrangement on the object. This can prevent the identification means from being accidentally removed from the object. For example, it can be provided that the identification means is attached to an object by means of an adhesive tape. A bracelet can be provided on the identification means to attach the identification means to the person.

More preferably, the identification means is designed as a transmitting and/or receiving unit. For this purpose it can be provided that the identification means has its own power supply and/or is connected to the power supply of the object if the object has a power supply. This enables active communication with the reporting system.

In special cases, the means of identification can be arranged on a hazard alarm, for example a fire alarm, which has no position determination means. In other words, the object can be a hazard detector. The position of the hazard detector can then be determined via the means of identification. This enables the particularly simple integration of the hazard detector into the reporting system. The identification means can preferably be removed and reused by the control unit after the position has been determined and the position of the hazard detector has been stored. This enables the particularly effective use of the means of identification.

Particular advantages can arise when the hazard detectors are linked to an open position determination system. "Open positioning system" means a positioning system whose interfaces, properties and communication protocol are described in such a public way that anyone who adheres to the rules, interfaces and protocols can use them. An example of an open position determination system that is already known in industrial applications is omlox, which is described, for example, at https://www.omlox.com.

In rooms in which an open position determination system, such as omlox, is already installed, it is also advantageous to provide individual, in particular all, hazard detectors with a compatible means of identification, so that the hazard detectors can be connected to the open, in particular omlox, system can be located. This simplifies the installation considerably, since the reporting units are automatically spatially located and displayed in the uniform, especially omlox, coordinate system. The fire alarm software can be easily connected here via the open, especially omlox, hub.

The position determination means make it possible to automatically determine the positions of other reporting units when setting up the reporting system. Furthermore, the position determination means make it possible to determine the position of the object with the identification means during operation of the reporting system. Furthermore, the position determination means can make it possible to determine the position of a hazard. The position determination means can thus serve multiple purposes in an efficient manner.

A preferred embodiment of the reporting system according to the invention is characterized in that the position determination means of at least one of the reporting units, preferably all reporting units, is designed for near-field position determination. As a result, the accuracy of the position determination can be improved. In near-field position determination, distances between two position determination means and/or one position determination means and an object to be located, for example a person to be located, are typically no more than 50 meters, preferably no more than 25 meters, particularly preferably no more than 10 meters.

In particular, the position determination means can be designed for position determination using ultra-wideband technology (UWB). As a result, the position determination can be carried out particularly precisely. With ultra-wideband technology, a bandwidth of radio signals can be at least 500 MHz in a frequency range between 3.1 and 10.6 GHz.

The position determination means is preferably designed for real-time position determination. The real-time position is typically determined by repeated position determinations at intervals of at most 1 second, preferably at most 250 milliseconds, particularly preferably at most 125 milliseconds. As a result, the position of the object to be located, for example the person to be located, can be reliably determined in the event of rapid changes in position.

In a preferred embodiment, the position determination means of at least one of the reporting units is designed to determine the position of a heat source and/or a source of toxic vapors. In this case, interference in the frequency range used for communication due to heat and/or vapors in the room is used to locate the source. In this case, the position determination means can take on the function of a further detector in a particularly advantageous and cost-effective manner.

In particular, several, particularly preferably all, position determination means are designed for determining the position of a heat source and/or a source of toxic vapors. As a result, the accuracy of the position determination of the source can be improved.

Also preferred is an embodiment in which the control unit is designed to output positions of the reporting units and/or the object in a pre-established coordinate system of the reporting system. In other words, the control unit performs a transformation of real positions into virtual coordinates. If necessary, in particular in the event of danger, the virtual coordinates can be output in order to indicate a specific real position, for example the location of a fire. This is preferably done on the basis of an open position determination system such as e.g. omlox.

In a development of this embodiment of the reporting system, the reporting system has a display for showing the positions of the reporting units and/or the object. A display promotes understanding of the positions of the reporting units inside the building. Preferably the display is a screen. The visual display further improves understanding of reporting unit locations.

Also preferred is an embodiment of the reporting system in which the position determination means and the detector of at least one of the reporting units are arranged on a common circuit board. As a result, the signaling unit can be made particularly compact and space-saving.

In a preferred embodiment, the reporting system is designed to document maintenance work on the building infrastructure. For example, the checking of the reporting system by a specialist can be monitored using an identification means arranged on the specialist and stored by the control unit. This allows access to the current maintenance status of the detection system and/or the building. When using an open position determination system, such as e.g. omlox, the monitoring can be implemented with open systems from any manufacturer. It is irrelevant here whether the reporting system itself serves as the base location infrastructure or whether an existing open base location system is used, in which the hazard detectors and the maintenance documentation units locate themselves.

Also preferred is an embodiment in which the reporting system for issuing warnings points is formed. The warnings preferably indicate an exact position of a potential danger point. As a result, the people or emergency services in the room can be warned of possible dangers depending on their position. These position reports are correct, even if the locations of the hazard detectors change in their life cycle. This can be the case, for example, when battery-powered hazard detectors are replaced or when hazard detectors are deliberately attached to moving objects such as drawbridges or scaffolding.

The reporting system described in this application can in particular have all the properties of the "location system" as described in the not yet published EP application with the acc. EP 20 175 059.3 is described, which has the title "Location system with UWB infrastructure and discovery infrastructure". The signaling units described in this application can be designed like the “trackable objects” described there. The EP application with the acc. EP 20 175 059.3 is fully incorporated by reference into this application.

The notification system described in this application can in particular have all the properties of the "location system" as described in the not yet published PCT application with the acc. PCT/EP2020/060911 entitled Ultra-Wideband Location Systems and Methods. The reporting units described in this application can be designed like the “mobile tag devices” described there. The PCT application with the acc. PCT/EP2020/060911 is fully incorporated by reference into this application.

Methods of the Invention

1. A) Anordnen der ersten Meldeeinheit im Gebäudeinnenraum;
2. B) Ermitteln von Abständen der ersten Meldeeinheit zu Referenzpunkten des Gebäudeinnenraumes mittels des Positionsbestimmungsmittels der ersten Meldeeinheit.

A method for setting up a reporting system for reporting dangers in a building interior and for determining the position of objects also falls within the scope of the present invention. The reporting system has a first reporting unit with a detector and a position determination means. The reporting system is preferably a reporting system according to the invention as described above. The procedure has the following procedural steps:

1. A) arranging the first reporting unit in the building interior;
2. B) Determination of distances of the first signaling unit to reference points of the building interior using the position determination means of the first signaling unit.

The signaling unit is preferably arranged on a wall, in particular a ceiling, of the interior of the building. This is advantageous with regard to trouble-free communication.

In special cases, provision can be made for the reporting unit to be arranged on immovably installed objects in the interior of the building. This enables the signaling unit to be arranged in areas in which, for example, a different arrangement would lead to increased expenditure.

The reference points are fixed points in the interior of the building whose absolute positions are known to the control unit. In other words, the reference points are defined points of the reporting system. This enables the particularly simple transformation of the determined distances of the reporting unit into the coordinate system of the reporting system or the building floor plan. In a preferred embodiment, these fixed points are elements of an open position determination system such as omlox and span a so-called “omlox core zone”.

When setting up the detection system, the reference points of the interior of the building are the starting point for determining the position of the first detection unit. For this purpose, the position determination means of the first signaling unit determines distances to the reference points. The first reporting unit can thus participate in determining its position in the interior of the building itself, thereby simplifying the setting up of the reporting system.

Communication means for communication with the reporting units can be arranged at the reference points. The distance determination via the position determination means of the first signaling unit can then be carried out in a particularly simple manner. The reference points are preferably freely accessible in order to avoid disrupting the communication.

In special cases, the first signaling unit can be arranged directly at a reference point. This enables a particularly precise position determination. In a preferred embodiment, this reporting unit becomes a reference point, preferably for an open position determination system such as e.g. omlox.

A development of the method according to the invention with the further method step is preferred: displaying a position of the first signaling unit in the interior of the building. This makes it possible to check whether the first signaling unit has been arranged at the intended position.

A preferred further development of the method is characterized in that the distances are determined automatically after the first signaling unit has been activated, in particular after a power supply has been established. This reduces the effort required to install the signaling unit.

• C) Anordnen der zweiten Meldeeinheit im Gebäudeinnenraum;
• D) Ermitteln eines Abstands der zweiten Meldeeinheit zu der ersten Meldeeinheit, und vorzugsweise von Abständen der zweiten Meldeeinheit zu Referenzpunkten des Gebäudeinnenraumes, mittels des Positionsbestimmungsmittels der zweiten Meldeeinheit.

Also within the scope of the present invention is a method for setting up a reporting system for reporting dangers in a building interior and for determining the position of objects, the reporting system having a first and a second reporting unit each with a detector and a position determining means. The first reporting unit is arranged in the building interior. The reporting system is preferably a reporting system according to the invention as described above. The procedure has the following procedural steps:

• C) arranging the second reporting unit in the building interior;
• D) Determining a distance between the second reporting unit and the first reporting unit, and preferably distances between the second reporting unit and reference points in the interior of the building, using the position determination means of the second reporting unit.

This method is preferably carried out together with or subsequently to the method according to the invention described above. Thus, process step C) can take place before or after process step B). In particular, process step C) can take place before, after or at the same time as process step A). Process step D) takes place after process steps A), B) and C).

In this method, the - already calibrated - first signaling unit is used to determine the position of the second signaling unit. In other words, to determine the position of the second reporting unit, the distances between the second reporting unit and the first reporting unit and preferably the reference points are determined. This increases the accuracy when determining the position of the second reporting unit.

By determining the distances between the (first and/or second) reporting units and the reference points of the interior of the building, the positions of the reporting units of the reporting system can be converted into coordinates of the reporting system or located in the building floor plan. When using open position determination systems, such as e.g. omlox, this can be done automatically by transfer to the central coordinate system, e.g. by the omlox hub.

The further method step preferably follows: displaying a position of the second signaling unit in the interior of the building. This makes it possible to check whether the second signaling unit has been arranged at the intended position.

The distances are preferably determined automatically after activation, in particular after a power supply has been established, of the second signaling unit. This further reduces the installation effort of the reporting system.

The distances can be determined by means of short-range position determination, in particular by using ultra-wideband technology (UWB). The use of UWB technology is particularly advantageous with regard to the accuracy of the position determination. With ultra-wideband technology, a bandwidth of radio signals can be at least 500 MHz in a frequency range between 3.1 and 10.6 GHz.

Further advantages of the invention result from the description and the drawing. According to the invention, the features mentioned above and those detailed below can each be used individually or collectively in any desired, expedient combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

character list

• 1 shows a schematic representation of a reporting system according to the invention with three reporting units and an external control unit;
• 2 shows a schematic flowchart of a method according to the invention.

1 shows a reporting system 10 with three reporting units 12a-c and a control unit 14.

The reporting units 12a-c are arranged within a building interior 16. In the present case, the control unit 14 is arranged outside the building interior 16 and has a communication connection (not shown in detail) to the reporting units 12a-c. In the present case, the control unit 14 also has a man-machine interface with a graphic display 18 and an input means 20 .

The reporting units 12a-c are arranged in the building interior 16 within communication range of one another. In other words, each reporting unit 12a-c can communicate directly with every other reporting unit 12a-c.

The reporting units 12a-c have at least one position determination means 22a-c for communication. In the present case, the reporting unit 12a has two position determination means 22a. In addition to distances, direction information can also be determined by two position determination means 22a, as a result of which the accuracy of the position determination can be improved.

The position determination means 22a-c are designed for wireless communication via radio, in particular via ultra-wideband radio (UWB).

In the present case, the reporting units 12a-c each have a battery 23a-c for power supply. This enables the particularly quick attachment of the reporting units 12a-c without their connection to the power supply of the building interior 16.

The reporting units 12a-c are designed to determine distances 26, 27 from reference points 24 of the building interior 16 and from the other reporting units 12a-c. The reference points 24 are defined points of the building interior 16 whose absolute position is stored in the control unit 14 . In an advantageous embodiment, these can be reference units of an open position determination system, such as e.g. omlox, which allow compatible communication with the reporting units 12a-c due to the openness of the system.

The distances 26, 27 between the reporting units 12a-c and from the reference points 24 are determined via the position determination means 22a-c of the reporting units 12a-c. For example, a radio signal transmitted by one of the reporting units 12a-c to determine the distance from the reference points 24 can be returned to the reporting unit 12a-c (i.e. the radio signal can be reflected at the reference points). For this purpose, a reflector can be arranged at each of the reference points.

Alternatively or additionally, a communication means (not shown in detail) adapted to the communication type of the position determination means 22a-c can be arranged at the reference points 24. The means of communication are typically designed for wireless communication via radio, in particular via ultra-wideband radio (UWB). In this case, the reference points 24 can also emit signals that are detected by the reporting units 12a-c. Both a unidirectional - where both sides can act as transmitters - and a bidirectional communication is conceivable. Such open self-locations are made possible by open positioning systems such as omlox.

The reporting system 10 monitors a building interior 16 for possible hazards.

The reporting units 12a-c have detectors 28a-c to identify the dangers. The detectors 28a-c are designed, for example, as fire alarms, gas alarms or counting tubes for detecting fires, gases and/or radiation. In addition, other types of detectors 28a-c can be provided. The reporting units 12a-c can have a number of detectors 28a-c for recognizing various hazards.

The functionality of the reporting system 10 is described below by way of example. The building interior 16 has hazardous goods 30 . The dangerous goods 30 can contain, for example, combustible and/or toxic substances which, in the event of an accident, can endanger the health of people and/or impair the building interior 16 in the form of large amounts of heat and/or gas. In the exemplary case of a dangerous goods 30 igniting, the fire is detected by the detector 28b of a reporting unit 12b located in the immediate vicinity of the dangerous goods 30 . The reporting unit 12b transmits the information about the fire to the control unit 14 for the purpose of initiating measures.

The thermal radiation from the fire leads to a local disruption in the communication of the position determination means 22a-c of the reporting units 12a-c. The position of the fire can be determined by the control unit 14 by determining the distance between the disturbance and the reporting units 12a-c by the position determining means 22a-c of the reporting units 12a-c. In this way, the initiation of measures, in particular the instruction of rescue workers and the opening of rescue routes, can be carried out in a targeted manner.

The reporting system 10 has an identification means 32 . In particular, the use of several, particularly preferably at least one hundred, identification means 32 is possible. The identification means 32 is basically freely movable within the building interior 16 . In the present case, the identification means 32 is arranged captively on an object 34 . The identification means 32 can be located within the building interior 16 by means of the reporting units 12a-c. Depending on the type of object 34, the position of rescue equipment and/or dangerous goods can be precisely determined at any time. In addition to the previously described functionality of the reporting system in the event of danger, this also represents effective preventive protection, since, for example, the accidental storage of various dangers reproductive substances in close proximity to one another can be prevented.

In addition, the emergency services (not shown) can be given precise information about the position and type of a possible hazard in the event of a hazard. As a result, safety for the emergency services can be further improved.

2 shows an exemplary sequence of a method 100 for setting up a reporting system 10, see 1 , in a schematic representation.

In a first method step 102, a first reporting unit 12a to be measured is arranged inside the building interior 16. An automatic calibration process is preferably triggered by activating the first reporting unit 12a. More preferably, the reporting unit 12a is activated by establishing the power supply to the reporting unit 12a.

In a subsequent method step 104, the first reporting unit 12a determines distances 26 from reference points 24 of the building interior 16 by means of its position determination means 22a. The determined distances 26 are then transmitted to the control unit 14 .

In a method step 106 , the control unit 14 uses the distances 26 to determine the position of the first signaling unit 12a within the building interior 16 and transforms the position into a coordinate system stored in the control unit 14 . The first reporting unit 12a has now been calibrated into the reporting system 10 and can be used to determine the position of further reporting units 12b-c. The determined position is then displayed in a method step 108 on a graphic display 18 of the control unit 14 .

To calibrate a second reporting unit 12b in the reporting system 10, this is arranged in a method step 110 in the building interior 16. After activating the second signaling unit 12b, preferably by establishing the power supply, in a method step 112 it determines the distances from the reference points 24 and a distance 27 from the first signaling unit 12a. After the position of the second signaling unit 12b has been determined by the control unit 14 in a method step 114, this can be displayed on the display of the control unit 14 in a method step 116.

Steps 110-116 can be repeated to calibrate further second signaling units 12c. As a result, the automatic calibration method can be used to set up and expand a reporting system 10 with a large number of reporting units 12a-c. In this case, the distances between the additional signaling units 12c to be newly measured and all signaling units 12a, 12b that have already been measured can be determined by the position determination means 22a-c.

Taking all the figures of the drawing together, the invention relates to a reporting system 10 for reporting hazards with a plurality of reporting units 12a-c and a control unit 14 and preferably an identification means 32, the components of the reporting system 10 communicating with one another for the purpose of position determination and transmission of information and a method 100 for automatically setting up a reporting system 10 by determining the distance between the reporting units 12a-c and from reference points 24 of the building interior 16.
