Description

[0001] The present invention relates to a safety system, in particular for monitoring and warning a person at a stationary facility. The invention further relates to a method.

[0002] Caring for people in inpatient facilities (e.g., nursing homes or hospitals) requires the utmost attention from the responsible care and nursing staff. Even minor errors in individual medication or lapses in monitoring essential vital signs can have serious negative consequences for an individual's health. Additionally, while patients leaving inpatient facilities on their own is often undesirable, it cannot always be prevented.

[0003] A technical solution for the automatic monitoring of facility exits and patients' vital signs can therefore provide enormous support and significantly relieve the burden on staff in inpatient facilities. However, such a solution places high demands on its capabilities, such as the reliable identification of critical situations. Furthermore, a high degree of flexibility must be guaranteed to allow for adaptation to the specific requirements of each care facility.

[0004] Conventional systems are therefore often technically very complex and / or lack sufficient reliability. One implementation of a safety system is described in US 2016 / 0321898 A1.

[0005] It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide improved and / or simplified monitoring of a person in a stationary facility.

[0006] The foregoing problem is solved by a security system having the features of claim 1 and by a method having the features of claim 13. Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings. Features and details described in connection with the security system according to the invention naturally also apply in connection with the method according to the invention, and vice versa, so that the disclosure relating to the individual aspects of the invention always makes, or can make, reciprocal references.

[0007] The problem is solved by a safety system for a stationary facility according to claim 1.

[0008] The monitoring of the person refers to position monitoring (location tracking) and, optionally, vital sign monitoring. Vital sign monitoring, in this context, means the monitoring of at least one vital sign of a patient, whereby the vital sign, in particular, allows conclusions to be drawn about the patient's state of health. The inpatient facility is preferably a care facility such as a nursing home, a particularly secure psychiatric ward, or the like. The facility can also be a hospital, or a specific, particularly secure, ward of a hospital. A secure ward or facility, in this context, means that the patients housed in the facility are not authorized to leave the facility on their own. The security system according to the invention can be designed to be at least partially arranged on a building, preferably attached to it.In particular, the radio units described below can be arranged at at least one input and / or output of the facility.

[0009] The safety system according to the invention comprises the features of claim 1.

[0010] It may be provided that the monitoring arrangement is implemented as a backend IT system in order to control and / or configure the security system according to the invention.

[0011] In this context, a geographical boundary refers to a virtual boundary around or within the inpatient facility, within which patients are to remain or which they are not to leave. It may be sufficient for the boundary to be limited to local boundary points. For example, it may be sufficient to define only the exits of an inpatient facility as relevant nodes for the boundary. If a patient's approach to the boundary or to one of the nodes is detected, a tracking function on a portable device and / or an alarm function of the security system can be activated.

[0012] In other words, once activated, the alarm function allows for repeated, continuous, and / or regular tracking of the portable device that has approached or crossed the geographical boundary. This repeated tracking can continue until the security system's alarm function is deactivated. Activating the alarm function can also involve informing or alerting the responsible staff of the facility about the specific hazard. This can be done using acoustic and / or visual signals. This provides both an indication, for example, to the facility staff, that the person with the portable device has crossed the boundary, and a means of locating the person, as the device's position can be determined. The boundary could, for example, be defined by...The facility's exits are included, such that crossing them indicates that the portable device or person has left the facility. The alarm function can transmit the location data, for example, to a mobile communication device. It is conceivable that the position of at least one portable device could be displayed on the communication device, particularly visually.

[0013] The portable device may further comprise at least one, in particular several, preferably all of the following components: a (especially electronic) tracking component for determining the (geographic) position of the portable device, i.e.In particular, to determine the geographical position of the portable device, a (particularly electronic) receiving component for receiving at least one communication signal, especially wireless; a (particularly electronic) transmitting component for transmitting at least one communication signal, especially wireless; a (particularly electronic) processing component for activating position determination, preferably activating the location component and / or switching from a power-saving mode to an operating mode, depending on the receipt of at least one communication signal, especially wireless; a (particularly electronic) output component for outputting acoustic signals, especially a loudspeaker; a (particularly electronic) input component for inputting acoustic signals, especially a microphone; a (particularly electronic) light component, especially an LED. a (especially electronic and / or touch-sensitive) display component for visualizing information, in particular for visualizing warnings and / or person-specific or patient-specific data.

[0014] At least one wireless communication signal can be a radio signal, preferably a WLAN signal.

[0015] The electronic output component offers the advantage of transmitting acoustic signals, warnings, and / or instructions to the user of a portable device. The input component enables voice communication with the user. The light component allows for an additional visual warning function to be activated on the portable device. The display unit allows for the display of personal data such as name, origin, and / or medication on the portable device, significantly simplifying assistance for disoriented individuals.

[0016] The security system according to the invention can comprise several components that can communicate with each other, particularly wirelessly, to enable monitoring of the stationary installation. In particular, the security system according to the invention can include several radio units and / or several portable devices. Monitoring can be energy-efficient. For this purpose, at least the radio units of a security system according to the invention can form a radio network, in particular a mesh network. In other words, each radio unit of a security system according to the invention can communicate, in particular wirelessly, with at least one other radio unit, and in particular with several other radio units.It can also be provided that not all radio units, in particular only one radio unit, are in preferably direct communication with the monitoring arrangement of the security system according to the invention. It can also be provided that at least one radio unit is in communication with another network, in particular the Internet, via the monitoring arrangement.

[0017] It can also be provided that at least one, and in particular each, radio unit of the security system according to the invention is designed for wireless communication with at least one portable device, and in particular several portable devices. In other words, the portable devices or the portable device of a security system according to the invention can enter into a preferably reciprocal connection or communication with each radio unit of the security system and receive data from it or transmit it to it.

[0018] Within the scope of the invention, it can be provided that a portable device communicates with only one radio unit at a time. In other words, it is conceivable that a portable device, while potentially able to communicate with all radio units, only establishes a data connection with one radio unit for the purpose of communication, i.e., does not communicate with multiple radio units simultaneously. The radio unit used for communication can be selected, for example, based on the signal strength of a signal, particularly a wireless one. Thus, it can be provided that the portable device selects the radio unit with the highest signal strength for internal system communication. This offers the overall advantage of keeping communication paths within the security system short.Accordingly, the receiving and transmitting components of portable devices can be designed to be extremely energy-efficient, resulting in longer operating times when using batteries or rechargeable batteries.

[0019] It is also conceivable that a portable device communicates with multiple radio units. In other words, it is conceivable that a portable device is simultaneously in communication with multiple radio units of the security system according to the invention. The radio units used for communication can be selected, for example, based on the signal strength of a wireless communication signal from the respective radio units. Thus, it can be provided that the portable device selects, for the purpose of internal system communication, those radio units for which the portable device has determined the highest signal strengths. This offers the advantage that the position of a portable device within the stationary installation can be determined by means of the connection to multiple radio units.It is conceivable that the signal strength of the respective connections between the portable device and the individual radio units could be taken into account when determining the position, thereby increasing the accuracy of the position determination.

[0020] Within the scope of the invention, it is also conceivable that the positioning or location tracking component of a portable device is activated when the portable device communicates with one or more preferably predefined, system-limiting radio units of the security system according to the invention. The activation of the location tracking component can, for example, also include switching the location tracking component from an energy-saving mode to an operating mode. The initiation of communication between a portable device and a system-limiting radio unit can indicate that the portable device or the person carrying it is approaching the geographic boundary.

[0021] It is conceivable that the geographical boundary is configured by at least one, and in particular several, system-limiting radio units. In other words, at least one radio unit of the security system is defined or configured as a system-limiting radio unit. The configuration or definition of a radio unit as a system-limiting radio unit can be carried out via the monitoring arrangement. In other words, it is known, at least in the monitoring arrangement, which of the radio units function as system-limiting radio units. The monitoring arrangement can be designed such that every initiation of a communication link between a portable device and a radio unit is registered or can be registered by the monitoring arrangement. In this way, it can be automatically detected whether a portable device or a patient of the stationary facility is within range and thus in the vicinity of a system-limiting radio unit or not.If a communication link is registered between a system-limiting radio unit and a portable device, the tracking component or position determination of the portable device can be activated, in particular by sending a corresponding command from the monitoring arrangement. The command can preferably be transmitted wirelessly to the portable device using the radio units of the security system according to the invention and processed there, in particular by the processing component.

[0022] When a patient or resident of an inpatient facility approaches such a system-limiting radio unit, the patient's wearable device communicates with it. This allows the facility to detect when a patient is approaching the geographical boundary of the facility. Consequently, the possibility of a patient unintentionally leaving the facility must be anticipated, and appropriate measures, such as activating the tracking component of the patient's wearable device, can be initiated. Thus, location tracking is only activated when crossing the boundary is imminent or expected, and therefore tracking the wearable device may be necessary. Nevertheless, reliable tracking can be achieved in the event of a boundary violation.This offers the advantage that the location tracking component of a portable device is only activated when needed, thus enabling energy-efficient operation of the portable device.

[0023] Advantageously, the activation of the positioning function on a portable device can remain active at least as long as the portable device is communicating with a system-limiting radio unit. Furthermore, the activation can remain active permanently and / or the alarm function can be activated after the portable device has crossed the boundary (e.g., the geofence). In other words, the activation of the positioning component can remain active permanently and / or the alarm function can be activated if communication between the portable device and a system-limiting radio unit has been interrupted and the portable device has not instead entered communication with another radio unit of the security system according to the invention, i.e., in particular, if there is no communication between a radio unit of the security system according to the invention and the portable device. In this regard, it is conceivable that the positioning component or the alarm function could then remain active.Position determination can only be deactivated, for example, by the end of the battery charge of the portable device and / or by resetting using a function button on the portable device and / or by resetting by the monitoring arrangement and / or upon exceeding the limit again or establishing a communication connection between the portable device and a radio unit.

[0024] If, after activation of the tracking component and termination of communication between a portable device and the radio units of a security system according to the invention, renewed communication is initiated between a radio unit and the portable device, or is registered by the security system, in particular the monitoring arrangement, the positioning or tracking component can be automatically deactivated again after a specific security interval (e.g., 5 minutes) has elapsed. The deactivation can be carried out by the monitoring arrangement. The radio unit can be implemented, for example, as a Bluetooth transmitter, but also as a WLAN transmitter (such as an access point) or the like. Position determination by the tracking component can be carried out, for example, using GPS.

[0025] The security system according to the invention is advantageously designed as an information technology (IT) system and / or as an assistance system. The system can be configured and thus adapted to the specific requirements of a stationary facility. For this purpose, a data storage device can be provided in which at least one configuration file is stored. The data storage device can be part of the monitoring arrangement or integrated into the monitoring arrangement. The security system according to the invention is therefore highly customizable. In this way, the security system can reliably support both staff and residents in facilities from a security perspective.In this context, it is conceivable that, as part of the security system configuration, at least one, and in particular several, patients in the inpatient facility could be assigned to a specific portable device, which the respective patients would carry with them at least temporarily, and especially permanently. This offers the advantage that a portable device can be directly linked to a specific person or patient. If the system detects, for example, that a portable device has left the facility, the subsequent measures can be at least partially tailored to the individual patient in question.

[0026] It is conceivable that the configuration of the safety system according to the invention can be carried out via the monitoring arrangement. It is also conceivable that a portable device for use within the system must first be registered or authorized in the safety system according to the invention via the monitoring arrangement and can then be assigned to a specific person or patient.

[0027] When assigning a patient or person to a portable device, it is conceivable that at least one of the following pieces of information, particularly personal information, may be stored in the security system, especially in the monitoring order or a data storage device of the monitoring order and / or on the portable device or in the data storage device of the portable device: Name of the person, name and contact details (address, telephone number and the like) of the inpatient facility, illnesses of the person, medication of the person.

[0028] In particular, it is conceivable that the aforementioned personal information is stored in the monitoring order as part of the patient's admission and is automatically transferred to the portable device assigned to the patient, preferably using the radio units of the security system according to the invention.

[0029] It may be possible for the aforementioned data to be displayed, at least partially, on the display component of a portable device after activation of its tracking component or alarm function. This offers the advantage of significantly simplifying assistance in the event of locating a potentially disoriented person who has left the facility without authorization.

[0030] It is also conceivable that activating the tracking component and / or the alarm function triggers the activation of the light component on the portable device. This activation can result in a preferably regular flashing or a continuous, preferably colored, illumination of the light component. This has the advantage that potential helpers can be alerted more quickly to a possibly disoriented person carrying the portable device.

[0031] The security system according to the invention can be configured for monitoring within the facility, preferably for monitoring inside ("in-house tracking") and / or outside the facility. Accordingly, radio units can be provided at least at the outputs of the facility. Of course, it is also conceivable that radio units could be provided in other areas of the facility as well.

[0032] With regard to determining the position of a portable device (or a patient within the stationary facility) within the facility or within the geographical boundary defined, in particular by system-limiting radio units ("in-house tracking"), it is conceivable that the position determination is not carried out by the tracking component of the portable device, but by the radio units of the security system according to the invention. In other words, it is conceivable that the security system according to the invention, in particular by the monitoring arrangement, registers which portable device is currently communicating with which radio unit or units. Particularly when using stationary radio units whose installation location is known, the position of a portable device within a stationary facility can thus be determined with sufficient accuracy.Increasing the number of radio units improves the accuracy of the positioning. This offers the advantage that the position of portable devices or patients in stationary facilities can be continuously monitored without relying on the tracking component of the portable devices themselves. This results in more energy-efficient operation of the portable devices and a correspondingly longer operating time when using batteries or rechargeable batteries.

[0033] Regarding "in-house tracking," it can be stipulated that the position of a portable device is updated whenever it communicates with at least one, preferably new, radio unit. In other words, the position of a portable device is updated only when communication is initiated between at least one radio unit and the portable device, but not when communication is merely maintained between one or more radio units. This has the advantage of reducing the amount of data communicated within the security system.

[0034] It can be configured that the security system's alarm function is also activated if no movement is registered with respect to a portable device within a defined period. In other words, the alarm function can be activated if the portable device has been in communication with only one or more identical radio units for a predefined period, or if no movement of the portable device has been detected. Such activation of the alarm function can also be limited to specific time periods (e.g., during nighttime hours). Furthermore, such activation of the alarm function can be individually configurable for a specific portable device based on the different radio units. For example, it is conceivable that radio units located near a bedroom or...A patient's room is excluded from this type of alarm activation because the patient, and with them the portable device, is usually in the room for an extended period of time. This has the advantage that any emergencies are detected automatically and early, and appropriate assistance can be initiated.

[0035] It may be stipulated that "in-house tracking" is not carried out continuously, but only during defined periods, particularly during nighttime hours and / or in the event of emergencies such as fires. This offers the advantage that, in the event of an emergency, it can be determined whether people requiring assistance are still in the facility and where they are currently located.

[0036] The safety system according to the invention can also be designed to extend and / or supplement an existing safety system, or can be connected to or integrated into an existing safety system. For example, it is conceivable that the system according to the invention can be connected to or integrated into existing safety systems such as a fire alarm system. This offers the advantage that warnings and / or alarms from existing safety systems can be received by the safety system according to the invention, particularly by the monitoring arrangement. It is also conceivable that such an alarm or warning message is forwarded by the safety system according to the invention, particularly by the monitoring arrangement, to all or selected portable devices of the safety system according to the invention. This offers the advantage that patients in inpatient facilities can be effectively warned of hazardous situations.It may be intended that in such an emergency the display component and / or the output component and / or the light component and / or the location component of the portable device is used to warn a resident or patient of the inpatient facility or to initiate and / or coordinate appropriate assistance measures.

[0037] It is also conceivable that, in the event of a warning and / or alarm from an existing security system, such as a fire alarm system, the tracking components or the position determination of all portable devices of the security system according to the invention are activated. This offers the advantage that people within the stationary facility can be located even more precisely and reliably and brought to safety from danger.

[0038] For example, the portable device may be designed to be worn directly on the person's body, and in particular may be in the form of a wristwatch (especially a smartwatch). In this way, the portable device can be designed as an "on-body device" that the person wears on their body or wrist. This enables the reliable tracking of the person both within and outside of a stationary facility or geographical area. The portable device can also be designed as a "wearable device" according to "wearable technology".

[0039] This means that the wearable device is designed as a "smart," or "intelligent," electronic device that is worn close to and / or on the skin's surface. In this way, the device can collect, analyze, and transmit information about, for example, bodily signals such as vital signs and / or environmental data using at least one sensor.

[0040] To be used in the safety system according to the invention, the portable

[0041] The device must be designed to receive a wireless communication signal and transmit it via the transmitting component, e.g., to the monitoring system and / or at least one radio unit. Furthermore, the portable device may be programmable and / or configurable by the monitoring system. For this purpose, a processing unit can, for example, send configuration commands and / or a computer program to the portable device and activate it there. The transmitted data is stored, for example, in a data memory of the portable device. Advantageously, the transmission can be contactless.

[0042] It is also advantageous if the radio unit is positioned according to the boundary in order to transmit the communication signal in and / or on the stationary device within an area around the boundary, preferably activating the positioning function for detecting a boundary violation when the portable device approaches the boundary. This eliminates the need for positioning to be continuously active to reliably locate a person who has left the facility.

[0043] It is conceivable that the portable device has at least one signal transmitter, in particular a sensor, to record at least one preferably personal parameter, such as at least one bodily signal (e.g., vital signs of the person) and / or environmental data. Furthermore, a processing component of the portable device can be in signal communication with the signal transmitter or sensor to analyze the at least one recorded parameter. The at least one parameter can preferably be transmitted to the monitoring system by the transmitting component. It can also be provided that the transmission of the at least one parameter occurs regularly and / or several times a day, preferably at least four times a day, and most preferably at least hourly.This offers the advantage that the vital parameters of patients can be continuously monitored via the safety system according to the invention, and health problems as well as the need for action by staff can be identified in a timely and reliable manner.

[0044] According to the invention, the location component of the portable device is configured to determine at least one geographic location coordinate for position determination, which specifies the position of the portable device. This also makes it possible to reliably determine the position of the person.

[0045] It may be possible for the geographic boundary ("geo-fence") to be defined independently of the functionality of the at least one radio unit, e.g., based on at least one GPS coordinate, and in particular, several GPS coordinates. The monitoring arrangement, which is implemented, for example, as a backend IT system to configure and / or control the security system according to the invention, can be used to define the boundary.

[0046] Furthermore, according to the invention, the monitoring arrangement comprises at least one processing device to provide at least one geographical boundary coordinate for defining the geographical boundary and to compare the at least one boundary coordinate with the at least one determined location coordinate for detecting a boundary violation. The violation can be detected by this comparison. Based on the boundary, the monitoring arrangement can trigger an alarm, for example, as part of the alarm function, when the boundary is exceeded by the portable device. The alarm function can include transmitting the alarm, for example, to a communication device.

[0047] Optionally, the monitoring system could be configured, after activation, to execute the activated alarm function by repeatedly receiving at least one geographic location coordinate from the tracking component to locate the portable device. This coordinate would then be used to determine the device's position. These repetitions could be performed at intervals of less than one minute to reliably detect the portable device's movement.

[0048] It is also optionally conceivable that the monitoring arrangement and the portable device each have a communication interface, preferably a mobile communication interface and / or internet interface and / or network interface, in order to transmit the location coordinate from the location component of the portable device to a processing device of the monitoring arrangement. If the portable device is designed as a mobile communication device, for example, a mobile communication base station can be used as the communication interface.

[0049] Furthermore, within the scope of the invention, it is optionally possible for the positioning component to be configured as a GNSS receiver (GNSS stands for "global navigation satellite system"), preferably a GPS receiver (GPS stands for Global Positioning System). The use of AGPS (Assisted Global Positioning System) and LBS (Location-Based Services) is also possible, so that the positioning component can also be implemented as an AGPS and / or LBS receiver. This can further improve the position determination or positioning by increasing the accuracy.

[0050] The radio unit can be designed such that the transmission range, based on the transmission of at least one wireless communication signal (e.g., with a resolution of at least one meter), can be adjusted. This makes it possible to take environmental influences (walls, obstacles) into account during installation and to adjust the transmission range accordingly. This also reduces the frequency of false alarms, since, in particular, the communication between system-limiting radio units and portable devices of the safety system according to the invention can be reduced to the smallest possible communication area, restricted to the geographical boundaries.

[0051] The radio unit can be specifically designed for indoor or outdoor use. For example, the radio unit for outdoor use has a waterproof housing.

[0052] Furthermore, it is conceivable that the monitoring system includes a knowledge base. This knowledge base can comprise at least one rule that defines a dependency for activating the alarm function. For example, the alarm function could be activated upon detection of a boundary violation and / or upon detection of at least one event and / or upon detection of at least one signal from a transmitter. The knowledge base could, for instance, include a data storage device containing the at least one rule. If the boundary violation is detected and / or at least one event is received and / or a signal from a transmitter is received, the rule can determine whether the alarm function is activated. The knowledge base could also be designed to be adaptive.In other words, by adapting the knowledge base, the activation of the alarm function can be individually tailored for each patient in the inpatient facility or for a portable device. For example, it can be specified whether an alarm should be activated upon detection of a geographical boundary violation. Threshold values ​​for bodily signals, particularly a patient's vital signs, can also be defined, whereby, depending on the definition, exceeding or falling below a specific threshold can trigger the activation of the alarm function.

[0053] A "learning ability" can be understood as the capacity to recognize certain behavioral patterns in a person. For example, historical data reveals which event patterns statistically preceded a person crossing a geographical boundary. If, for instance, historical data shows that individuals frequently visited specific locations within the facility before crossing the boundary, this event pattern can modify the rule so that activation is more likely when the event pattern is present. These event patterns can be detected, for example, by additional radio units distributed throughout the facility. These event patterns, specific to crossing the boundary (i.e., leaving the facility), can then be stored in the knowledge base. Furthermore, the event patterns and / or historical data can also include time information. For example...A rule in the knowledge base might state that approaching a boundary at a specific time of day (night) is more likely to result in crossing the boundary than at other times. Similarly, detecting a portable device or a patient approaching a geographic boundary at night might trigger the alarm earlier than at other times. In other words, detecting event patterns based on these rules can prioritize location tracking and / or alarm activation. The knowledge base can continuously evolve through statistical analysis of these event patterns, thus enabling it to learn.

[0054] The use of a knowledge base also has the advantage that the safety system according to the invention becomes capable of learning and, based on the knowledge base, can, for example, automatically suggest measures or automatically trigger alarm and rescue chains within the framework of the alarm function.

[0055] A further advantage of the invention can be achieved if the monitoring arrangement is designed to automatically adapt and / or extend at least one rule of the knowledge base based on historical data, in particular past activations of the alarm function and / or event patterns. Since the portable device may be connected to a charging station at night, it is possible to include other components for activating the alarm function from the outset. For example, other portable and / or stationary devices, such as "contact mats," can be used to trigger the activation of the alarm function and / or to determine position. These devices can also transmit further event information to the monitoring arrangement.

[0056] A further advantage can be achieved within the scope of the invention if the processing component is configured to initiate a transmission of event information to the monitoring arrangement depending on the receipt of the preferably wireless communication signal, wherein the monitoring arrangement can be configured to receive the event information and / or at least one further event information about an event at the person from at least one further device, and to activate the alarm function depending on the receipt of the event information - in particular on the basis of at least one rule of a knowledge base.

[0057] According to the invention, the monitoring arrangement is completely separate from the portable device.

[0058] The device includes at least one radio unit. For example, the monitoring arrangement comprises at least one processing device in the form of a data processing system such as a server and / or computer, and is preferably part of a cloud, and thus usable via a network such as the Internet.

[0059] According to an unclaimed embodiment, the definition of the geographical boundary and / or the detection of boundary violations can be performed by the portable device itself, and / or the alarm function can optionally be activated and / or executed by the portable device itself. Accordingly, the portable device can itself make an emergency call when executing the alarm function, e.g., directly alerting the emergency services. According to the invention, the portable device can communicate with the monitoring arrangement via a communication network such as the internet in order to execute the definition of the geographical boundary and the detection of boundary violations and / or the alarm function outside of the portable device.

[0060] It is conceivable that the monitoring arrangement, e.g., in the form of backend IT, could also be used to parameterize the security system according to the invention and to integrate further components (e.g., temporarily or permanently). Accordingly, the security system can also be expandable, e.g., by adding further portable devices and / or radio units.

[0061] Furthermore, it can be advantageous within the scope of the invention to provide a communication device for detecting the activation of the alarm function and / or for locating the portable device and / or for making an emergency call when the alarm functions are activated. The communication device is, for example, a portable device such as a mobile phone, in particular a smartphone, and / or a computer such as a laptop. The communication device can be configured to visualize the position of the portable device on a display of the communication device by means of location tracking. For this purpose, the location coordinates can be evaluated, for example. It is also possible for the communication device to transmit the position of the portable device to an emergency call center (and thus to rescue services) upon detection of the activated alarm function.It is also conceivable that the communication device is designed to establish an audio and / or video telephone connection with the portable device in order to speak with the person when the alarm function is activated. The activation of the alarm function is detected by the communication device, for example, when it receives an alarm (data or a message) transmitted by the portable device and / or the monitoring system. The communication device can be in data communication with the transmission system to detect the activation of the alarm function.

[0062] It is also optionally conceivable that the monitoring arrangement and / or the portable device has at least one signal transmitter to activate the alarm function depending on a signal from the signal transmitter, wherein the at least one signal transmitter can be designed as at least one of the following: an interface to other medical devices, such as a FHIR interface (Fast Healthcare Interoperability Resources interface), an FHIR interface to receive the signal from a medical device, a sensor to detect a parameter of the person and / or in the environment of the portable device, and preferably to generate the signal based on the detection.

[0063] This enables extensive functional expansion through the integration of medical devices. The system according to the invention can be significantly enhanced by integrating medical devices into the system (e.g., via the FHIR interface). These medical devices can then function as signal transmitters (e.g., for critical situations). Location (indoors or outdoors) or specific values ​​of the connected devices can trigger various types of alarms.

[0064] The invention also relates to a method according to claim 13.

[0065] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination. The drawings show: Fig. 1 a schematic representation of a system according to the invention when integrated into a stationary device, Fig. 2 a schematic representation for visualizing a method according to the invention.

[0066] In the following figures, identical reference numerals are used for the same technical features even for different embodiments.

[0067] In Figure 1A safety system 1 according to the invention for a stationary device 2 is shown. The safety system 1 has several radio units 10 for the stationary device 2 for transmitting a radio signal 210, wherein one radio unit 10 is configured at an output of the stationary device as a system-limiting radio unit 10.1. Furthermore, at least one portable device 100 for a person 3 of the stationary device 2 is provided, which is shown schematically in an additional, enlarged view in the figure.The portable device 100 can therefore have a tracking component 110 for determining the geographic position 305 of the device 100, a transmitting component 115 for transmitting a communication signal, an output component 125 for outputting acoustic signals, an input component 135 for inputting acoustic signals, a light component 145, a display component 155, a signal transmitter 130, and a receiving component 120 for receiving 302 the communication signal 210, as well as an electronic processing component 140, the latter to activate the position determination 305 depending on the receipt 302 of the communication signal 210. For this purpose, the processing component 140 can be electrically or electronically connected to the receiving component 120 and the tracking component 110.At least some, preferably all, of the components 110, 115, 120, 125, 130, 135, 140, 145 can be arranged together on a printed circuit board, and each may have at least one integrated circuit.

[0068] Furthermore, at least one monitoring arrangement 20 is provided for defining 311 a geographical boundary 200 (dashed line) and for detecting 312 a crossing of the boundary 200 by the portable device 100 by the monitoring arrangement and / or based on the position determination 305, in order to activate an alarm function depending on the detection 312, which includes the location of the portable device 100 by means of the position determination 305. For example, when the alarm function is activated, in addition to an alarm (e.g., visual and / or acoustic), location tracking can also be initiated.

[0069] The tracking component 110 of the portable device 100 is configured to determine at least one geographic location coordinate for position determination 305, which specifies the position of the portable device 100. For this purpose, the monitoring arrangement 20 comprises at least one processing device 30 to provide at least one geographic boundary coordinate for defining the geographic boundary 200, and to compare the at least one boundary coordinate with the at least one determined location coordinate for detecting 312 the crossing of the boundary 200. This enables the provision of a so-called geofence function.

[0070] Furthermore, the monitoring arrangement 20 and the portable device 100 can each have a communication interface 150, preferably a mobile communication interface and / or internet interface and / or network interface, to transmit the location coordinate from the location component 110 of the portable device 100 to a processing device 30 of the monitoring arrangement 20.

[0071] It is further possible that the monitoring arrangement 20 has a knowledge base 90 which includes at least one rule that defines a dependency of the activation of the alarm function on the detection 312 of the exceeding of the limit 200 and / or on at least one event piece of information and / or on a signal from a signal transmitter 130. The monitoring arrangement 20 can be configured to automatically adapt and / or extend the at least one rule of the knowledge base 90 depending on historical data, in particular past activations of the alarm function.

[0072] Furthermore, a communication device 80 may be provided to detect the activation of the alarm function and / or to locate the portable device 100 and / or to make an emergency call when the alarm functions are activated. The monitoring arrangement 20 and / or the portable device 100 may also have at least one signal transmitter 130 to activate the alarm function depending on a signal from the signal transmitter 130.

[0073] In Figure 1Furthermore, an exemplary arrangement of the safety system according to the invention in a facility 2 is shown. It can be seen that a person 3 can enter the ground floor, for example, coming from a staircase. This requires that the person 3 wears a suitable portable device 100 capable of detecting the radio units 10 mounted in the facility. If the person 3 initially moves, for example, in the direction of the system-limiting radio unit 10.1, the position determination or the location component can be activated on the portable device as soon as the portable device 100 communicates with the system-limiting radio unit 10.1. If the person 3 then moves in the direction of the elevators and thus out of range of the communication signal 210 of the system-limiting radio unit 10.1 and is instead within range of a non-system-limiting radio unit 10, a position determination 305 activated by the portable device 100 (e.g., the radio unit 10) can be activated.B. GPS functionality) will be switched off or deactivated again after a certain period of time.

[0074] However, if person 3 leaves facility 2 and crosses the boundary 200 (geofence), the alarm function can be activated, particularly if there is no longer a connection between the system-limiting radio unit 10.1 or another radio unit 10 and the portable device 100. This can trigger, for example, an emergency signal to the communication device 80 or (depending on a configuration) directly to a defined address, such as that of emergency services. The radio units 10 can be installed at suitable locations outdoors and / or indoors to ensure that the position tracking 305 remains active.

[0075] In Figure 2An exemplary method according to the invention is visualized. First, a communication signal 210 is transmitted 301 by at least one radio unit 10 to the stationary device 2. Subsequently, a geographic position determination 305 is provided by a tracking component 110 of a portable device 100 in order to determine the position of the portable device 100.

[0076] Furthermore, the communication signal 210 is received 302 by a receiving component 120 of the portable device 100. In addition, the position determination 305 is activated by an electronic processing component 140 of the portable device 100, depending on the receipt 302 of the communication signal 210. Moreover, a geographical boundary 200 is defined 311 by at least one monitoring device 20, and the monitoring device 20 detects 312 when the portable device 100 crosses the boundary 200, in order to activate an alarm function, depending on the detection 312 of the crossing, which includes locating the portable device 100 by means of the position determination 305.

[0077] The preceding explanation of the embodiments describes the present invention solely by way of examples. Naturally, individual features of the embodiments can be freely combined with one another, provided this is technically feasible, without departing from the scope of the present invention as defined in the claims.
