Description

The present invention relates to a security system, in particular for monitoring and warning a person in a stationary facility. The invention further relates to a method.

Caring for people in inpatient facilities (e.g. inpatient care facilities or hospitals) requires the highest level of attention from the responsible care or nursing staff. For example, even small errors in the individual medication of patients or inattention with regard to monitoring essential vital parameters of patients can have strong negative effects on the health of individuals. There is also the problem that patients leaving inpatient facilities on their own is often undesirable, but cannot always be avoided.

A technical solution for automatic monitoring of facility exits and patient vital parameters can therefore provide enormous support and significantly reduce the workload on the staff of an inpatient facility. However, high demands are placed on such a solution, such as the reliable identification of critical situations. A high level of flexibility must also be guaranteed in order to be able to adapt to the requirements of a specific care facility.

Conventional systems are therefore often technically very complex and/or do not have sufficient reliability.

It is therefore an object of the present invention to at least partially eliminate 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.

The above object is achieved by a security system with the features of claim 1 and by a method with the features of claim 14. Further features and details of the invention result from the respective subclaims, the description and the drawings. Features and details that are 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 reference is or can always be made to each other with regard to the disclosure of the individual aspects of the invention.

The task is solved in particular by a security system for a stationary facility, in particular for monitoring a person at the stationary facility. The monitoring of the person can at least refer to position monitoring (locating) and/or vital monitoring. In the present case, vital monitoring means the monitoring of at least one vital parameter of a patient, the vital parameter in particular enabling a conclusion to be drawn about a patient's health condition. The inpatient facility is preferably a care facility such as a retirement home, a particularly closed psychiatric hospital or the like. The facility can also be designed as a hospital, or as a specific, especially closed ward of a hospital. In this case, a closed ward or facility means that the patients staying 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, preferably attached, to a building. In particular, the radio units described below can be arranged at at least one input and/or output of the device.

• wenigstens eine (insbesondere elektronische und/oder stationäre und/oder mobile) Funkeinheit für die stationäre Einrichtung zum Aussenden und/oder Empfangen wenigstens eines insbesondere drahtlosen Kommunikationssignals,
• wenigstens ein (insbesondere elektronisches) tragbares (und damit mobiles) Gerät für wenigstens eine Person (in der stationären Einrichtung),
• wenigstens eine (insbesondere zumindest teilweise elektronische, vorzugsweise zentrale) Überwachungsanordnung insbesondere zum Definieren einer geografischen Begrenzung und/oder zum Detektieren eines Überschreitens der Begrenzung und/oder einer Annäherung an die Begrenzung durch das tragbare Gerät insbesondere anhand einer (geografischen) Positionsbestimmung (einer Position) des tragbaren Geräts, vorzugsweise um in Abhängigkeit von dem Detektieren des Überschreitens eine Alarmfunktion zu aktivieren, welche die (insbesondere wiederholte) Ortung des tragbaren Geräts mittels der Positionsbestimmung umfasst.

The security system according to the invention includes in particular:

• at least one (in particular electronic and/or stationary and/or mobile) radio unit for the stationary device for sending and/or receiving at least one, in particular wireless, communication signal,
• at least one (in particular electronic) portable (and therefore mobile) device for at least one person (in the stationary facility),
• at least one (in particular at least partially electronic, preferably central) monitoring arrangement, in particular for defining a geographical boundary and/or for detecting an exceeding of the boundary and/or an approach to the boundary by the portable device, in particular on the basis of a (geographical) position determination (a position) of the portable device, preferably in order to activate an alarm function depending on the detection of the exceedance, which includes the (in particular repeated) location of the portable device by means of the position determination.

It can be provided that the monitoring arrangement is designed as backend IT in order to be able to control and/or configure the security system according to the invention.

In the present case, a geographical boundary means a particular virtual boundary around or in the inpatient facility, within which the patients of the inpatient facility should stay or which patients of the inpatient facility should not leave. It may be sufficient that the Boundary limited to local boundary points. It may be sufficient for only the exits of a stationary facility to be defined as relevant nodes for the boundary. If a patient's approach to the boundary or to one of the nodes is detected, a location function on a portable device and/or an alarm function of the security system can be activated, for example.

In other words, the alarm function can be used to locate the portable device that has approached and/or exceeded the geographical boundary repeatedly or persistently and/or regularly after activation. This repeated location can then continue until the alarm function of the security system is deactivated again. Activating the alarm function can involve informing the responsible staff of the inpatient facility about the respective dangerous situation or making them aware of it. For this purpose, it is conceivable that acoustic and/or visual signals are used. This provides both an indication, e.g. B. to the facility staff that the person with the portable device has exceeded the limit, as well as a way to locate the person since the position of the portable device can be located. The limitation can e.g. B. include the exits of the facility, so that exceeding them indicates that the portable device or person has left the facility. The alarm function can locate e.g. B. communicate with a particular mobile communication device. It is conceivable here that a position of at least one portable device on the communication device can be represented, in particular visually.

• eine (insbesondere elektronische) Ortungskomponente für die (geografische) Positionsbestimmung des tragbaren Geräts, d. h. insbesondere, um die geografische Position des tragbaren Geräts zu bestimmen,
• eine (insbesondere elektronische) Empfangskomponente zum Empfangen wenigstens eines insbesondere drahtlosen Kommunikationssignals,
  eine (insbesondere elektronische) Sendekomponente zum Aussenden eines wenigstens eines insbesondere drahtlosen Kommunikationssignals,
• eine (insbesondere elektronische) Verarbeitungskomponente, um in Abhängigkeit von dem Empfangen wenigstens eines insbesondere drahtlosen Kommunikationssignals die Positionsbestimmung zu aktivieren, vorzugsweise die Ortungskomponente zu aktivieren und/oder von einem Energiesparmodus in einen Arbeitsmodus zu überführen,
• eine (insbesondere elektronische) Ausgabekomponente zur Ausgabe akustischer Signale, insbesondere ein Lautsprecher,
• eine (insbesondere elektronische) Eingabekomponente zur Eingabe akustischer Signale, insbesondere ein Mikrofon,
• eine (insbesondere elektronische) Lichtkomponente, insbesondere eine LED.
  eine (insbesondere elektronische und/oder berührungssensitive) Anzeigekomponente zur Visualisierung von Informationen, insbesondere zur Visualisierung von Warnhinweisen und/oder personenspezifischen bzw. patientenspezifischen Daten.

The portable device can further comprise at least one, in particular several, preferably all, of the following components:

• a (in particular electronic) positioning component for determining the (geographical) position of the portable device, that is, in particular, to determine the geographical position of the portable device,
• a (in particular electronic) receiving component for receiving at least one, in particular wireless, communication signal,
  a (in particular electronic) transmission component for sending out at least one, in particular wireless, communication signal,
• a (in particular electronic) processing component in order to activate the position determination, preferably to activate the positioning component and/or to convert it from an energy-saving mode into a working mode, depending on the reception of at least one, in particular wireless, communication signal,
• a (particularly electronic) output component for outputting acoustic signals, in particular a loudspeaker,
• a (particularly electronic) input component for inputting acoustic signals, in particular a microphone,
• a (particularly electronic) light component, in particular an LED.
  a (in particular electronic and/or touch-sensitive) display component for visualizing information, in particular for visualizing warnings and/or person-specific or patient-specific data.

The at least one wireless communication signal can be a radio signal, preferably a WLAN signal.

The electronic output component has the advantage that acoustic signals or acoustic warnings and/or notices can be transmitted to the wearer of a portable device. The input component has the advantage that a voice connection can be established with the wearer of a portable device. The light component has the advantage that an additional visual warning function can be activated on the portable device. The display unit has the advantage that personal data such as name, origin and/or medication can be displayed on the portable device, which in turn considerably simplifies the provision of assistance to disoriented people.

The security system according to the invention can have several components which can communicate with one another, in particular wirelessly, in order to enable monitoring of the stationary device. In particular, it can be provided that the security system according to the invention comprises several radio units and/or several portable devices. Monitoring can be carried out in an energy-saving manner. For this purpose, it can be provided that at least the radio units of an inventive Security system form a radio network, in particular a mesh network. In other words, it can be provided that each radio unit of a security system according to the invention is in particular wireless communication with at least one further radio unit, in particular with several further 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, in particular via the monitoring arrangement.

It can also be provided that at least one, in particular each radio unit of the security system according to the invention is designed for, in particular, wireless communication with at least one portable device, 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 preferably mutual connection or communication with each radio unit of the security system and receive data from or send data to it.

Within the scope of the invention it can be provided that a portable device always only communicates with one radio unit. In other words, it is conceivable that a portable device can potentially communicate with all radio units, but only ever establishes a data connection with one radio unit for the purpose of communication, i.e. does not communicate with several radio units at the same time. The radio unit used for communication can be selected, for example, based on a signal strength of a particularly wireless signal. It can thus be provided that the portable device selects the radio unit for which the highest signal strength was determined by the portable device for the purpose of system-internal communication. This results in the overall advantage that the communication channels within the security system can be kept short. Accordingly, the receiving and transmitting components of the portable devices can be designed to be extremely energy-saving, which results in longer running times when using batteries or accumulators.

It is also conceivable that a portable device communicates with several radio units. In other words, it is conceivable that a portable device is in communication connection with several radio units of the security system according to the invention at the same time. The radio units used for communication can be selected, for example, based on a signal strength of a particularly wireless communication signal of the respective radio units. It can thus be provided that, for the purpose of system-internal communication, the portable device selects those radio units for which the portable device has determined the highest signal strengths. This results in the advantage that a position determination of a portable device in the stationary device can be carried out based on the connection to several radio units. It is conceivable that the signal strength of the respective connections between the portable device and the individual radio units are included in the position determination, whereby the accuracy of the position determination can be increased.

It is also conceivable within the scope of the invention that the position determination or the location component of a portable device is activated when the portable device comes into contact with one or more preferably predefined, system-limiting radio units of the security system according to the invention. The activation of the location component or the position determination can z. B. also include the transfer of the location component from an energy-saving mode to a working mode. The initiation of communication between a portable device and a system-limiting radio unit can indicate an approach of the portable device or the person carrying it to the geogeographical boundary.

It is conceivable that the geographical limitation is configured by at least one, 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 done 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 in such a way that every initiation of a communication connection between a portable device and a radio unit is registered by the monitoring arrangement or can be registered. This makes it possible to automatically detect whether a portable device or a patient in the stationary facility is within range and therefore close to a system-limiting radio unit or not. If a communication connection is registered between a system-limiting radio unit and a portable device, the location component or position determination of the portable device can be activated, in particular by sending a corresponding command by the monitoring arrangement. The command can preferably be transmitted wirelessly and using the radio units of the security system according to the invention to the portable device and processed there in particular by the processing component.

When a patient or resident of an inpatient facility approaches such a system-limiting radio unit, the patient's portable device enters into communication with it. This means that a patient's approach to the geographical boundary of an inpatient facility can be detected. An unintentional patient leaving the facility must therefore be expected and appropriate measures such as activating the tracking component of the patient's portable device can be initiated. The position determination is therefore only activated when it is possible or expected to exceed the limit in a timely manner, and the location of the portable device may therefore be necessary. Nevertheless, location can be reliably made possible if the limit is exceeded. This results in the advantage that the location component of a portable device is only activated as needed, which enables energy-efficient operation of the portable device.

The activation of the position determination on a portable device can advantageously remain at least as long as the portable device is in communication with a system-limiting radio unit. Furthermore, the activation can remain permanent and / or the alarm function can be activated after the portable device has reached the limit (i.e e.g. the geofence). In other words, the activation of the locating component can remain permanent and/or the alarm function can be activated if communication between the portable device and a system-limiting radio unit is interrupted and the portable device is not instead has entered into communication with another radio unit of the security system according to the invention, i.e. in particular 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 location component or position determination can then only be carried out, 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 when exceeded again limiting or establishing a communication connection between the portable device and a radio unit can be deactivated.

If, after activation of the locating component and termination of communication between a portable device and the radio units of a security system according to the invention, renewed communication between a radio unit and the portable device is initiated or registered by the security system, in particular the monitoring arrangement, the position determination or the locating component can automatically switched off again after a certain safety interval (e.g. 5 minutes). The shutdown can be carried out by the monitoring arrangement. The radio unit can e.g. B. be designed as a Bluetooth transmitter, but also as a WLAN transmitter (like an access point) or the like. The position determination by the location component can be carried out, for example, using GPS.

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 configurable and therefore adaptable to the specific requirements of a stationary facility. For this purpose, a data memory can be provided in which at least one configuration file is stored. The data memory 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 the staff and the residents in facilities from a security perspective. In this context, it is conceivable that, as part of a configuration of the security system, an assignment of at least one, in particular several, patients to the inpatient facility each of which takes place on a portable device, which is carried by the respective patient at least temporarily, in particular permanently. This results in the advantage that a portable device can be directly associated with a specific person or a specific patient. If, for example, the system detects that a portable device has left the facility, the following measures can be at least partially tailored individually to the patient in question.

It is conceivable that the configuration of the security 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 via the monitoring arrangement in the security system according to the invention and can then be assigned to a specific person or patient.

• Name der Person,
• Name und Kontaktdaten (Anschrift, Telefonnummer und dergleichen) der stationären Einrichtung,
• Erkrankungen der Person,
• Medikation der Person.

As part of the assignment of a patient or a person to a portable device, it is conceivable that at least one of the following, in particular personal, information is stored in the security system, in particular in the monitoring arrangement or a data memory of the monitoring arrangement and/or on the portable device or . stored in your data storage of the portable device:

• name of the person,
• Name and contact details (address, telephone number, etc.) of the inpatient facility,
• illnesses of the person,
• Medication of the person.

In particular, it is conceivable that the above-mentioned Personal information is stored in the monitoring arrangement as part of a recording of the patient and, preferably using the radio units of the security system according to the invention, is automatically transmitted to the portable device assigned to the patient.

It can be provided that the above-mentioned data is at least partially displayed via the display component of the portable device after activation of the location component of a portable device or the alarm function. This is the advantage The aim is to make it much easier to provide assistance if a possibly disorientated person is picked up and has left the stationary facility without authorization.

It is also conceivable that activation of the location component and/or the alarm function triggers activation of the light component on the portable device. The activation can result in a preferably regular flashing or a permanent, preferably colored glow of the light component. This has the advantage that potential helpers can be made more quickly aware of a possibly disoriented person who is carrying the portable device.

The security system according to the invention can be designed for monitoring in the facility, preferably for monitoring in the interior (“in-house location”) and/or in the exterior of the facility. Accordingly, radio units can be provided at least at the outputs of a device. Of course, it is also conceivable that radio units can also be provided in other areas of the facility.

With regard to the position determination of a portable device (or a patient in the inpatient facility) inside the facility or inside the geographical boundary formed in particular by system-limiting radio units ("in-house positioning"), it is conceivable that the position determination is not carried out by the Location 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 the monitoring arrangement, registers which portable device is currently connected to 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 device can be determined with sufficient precision. By increasing the number of radio units, the positioning accuracy can be improved accordingly. This results in the advantage that the position of portable devices or patients in the stationary facility can be monitored, in particular permanently, without having to resort to the location component of the portable devices. This results in energy-efficient operation portable devices and a correspondingly longer running time when using batteries or accumulators.

With regard to "in-house positioning", it can be provided that the position of a portable device is always updated when it comes into communication with at least one, preferably new, radio unit. In other words, the position of a portable device is only updated when communication between at least one radio unit and a portable device is initiated, but not if this is subsequently merely maintained between one or more radio units. This has the advantage that the amount of data communicated within the security system is reduced.

It can be provided that the alarm function of the security system is activated even if no movement has been registered in relation to a portable device in a defined period of time. In other words, the alarm function can be activated if the portable device was in communication with only one radio unit or several identical radio units for a predefined period of time or if no movement of the portable device was detected. Such activation of the alarm function can also be limited to certain periods of time (e.g. during the night's rest). Such activation of the alarm function can also be individually configurable for a specific portable device using the various radio units. For example, it is conceivable that radio units near a patient's bedroom or room are excluded from this type of activation of the alarm function, since the patient and with him the portable device are usually in the room for a longer period of time. This has the advantage that any emergencies can be identified automatically and early and appropriate assistance measures can be initiated.

It can be provided that the "in-house location" is not carried out permanently, but only in defined periods of time, in particular during nighttime rest and/or in the event of emergencies such as fires. This has the advantage that, in the event of an emergency, it can be determined whether people in need of help are still in the facility and where they are currently located.

The security system according to the invention can also be designed to expand and/or supplement an existing security system or can be connected or connected to an existing security system. It is therefore conceivable that the system according to the invention is connected or can be connected to existing security systems such as a fire alarm system. This results in the advantage that warnings and/or alarms from existing security systems can be or are received by the security system according to the invention, in particular by the monitoring arrangement. It is also conceivable that such an alarm message or warning message is forwarded by the security system according to the invention, in particular by the monitoring arrangement, to all or selected portable devices of the security system according to the invention. This has the advantage that patients in inpatient facilities can be effectively warned of dangerous situations. It can thus be provided that in such an emergency the display component and/or the output component and/or the light component and/or the locating component of the portable device is used to warn a resident or patient of the inpatient facility or to initiate appropriate assistance measures and /or to coordinate.

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

For example, it can be provided that the wearable device is designed to be worn directly on the person's body, and in particular is designed in the form of a wristwatch (in particular smart watch). This means that the portable device can be designed as an “on body device” that the person wears on their body or wrist. This enables the person to be reliably located both inside and outside the inpatient facility or geographical boundary. The portable device can also be designed as a “wearable device” according to “wearable technology”. This means that the wearable device is designed as a “smart”, i.e. “intelligent” electronic device that is worn close to and/or on the surface of the skin. In this way, it is possible for the device to capture, analyze and transmit information about, for example, body signals such as vital parameters and/or environmental data using at least one signal transmitter.

In order to be used in the security system according to the invention, the portable device can be designed to receive a particularly wireless communication signal and in particular also preferably to pass it on or send it out through the transmitting component, e.g. B. to the monitoring arrangement and / or at least one radio unit. Furthermore, it can be provided that the portable device is programmable and/or configurable by the monitoring arrangement. For this purpose, for example, a processing device can send configuration commands and/or a computer program to the portable device and activate it there. The transmitted data is z. B. stored in a data storage of the portable device. The transmission can advantageously be carried out contactlessly.

It is also advantageous if the radio unit is positioned depending on the boundary in order to transmit the communication signal in and/or on the stationary device in an area around the boundary, preferably in order to determine the position for detection when the portable device approaches the boundary when the limit is exceeded. It is therefore not necessary for the positioning to be permanently active in order to reliably locate a person who has left the facility.

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

It can be further advantageous to provide that the locating component of the portable device is designed to determine at least one geographical locating coordinate for determining the position, which indicates the position of the portable device. This also makes it possible to reliably determine the person's position.

It may be possible for the geographical boundary (“geo-fence”) to be defined independently of the functionality of the at least one radio unit, for example based on at least one GPS coordinate, in particular several GPS coordinates. To define the limitation, the monitoring arrangement can be used, which is designed, for example, as a backend IT in order to configure and/or control the security system according to the invention.

It may also be possible for the monitoring arrangement to comprise at least one processing device in order to provide at least one geographical boundary coordinate for defining the geographical boundary and/or in order to compare the at least one boundary coordinate with the at least one determined location coordinate in order to detect that the boundary has been exceeded. The comparison can be used to determine whether the limit has been exceeded. The monitoring arrangement can trigger an alarm based on the limit, for example as part of the alarm function, if the limit is exceeded by the portable device. The alarm function can transmit the alarm e.g. B. include a communication device.

Optionally, it is conceivable that the monitoring arrangement is designed to carry out the activated alarm function after activation by repeatedly receiving at least one geographical location coordinate from the location component in order to locate the portable device by means of the position determination in order to determine the position of the portable device based on the location coordinate to determine. The repetitions can be carried out at an interval of less than one minute in order to reliably record the movement of the portable device.

It is also optionally conceivable that the monitoring arrangement and the portable device each have a communication interface, preferably a mobile radio 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, for example, as a mobile device, a mobile station can be used as the communication interface.

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

The radio unit can be designed in such a way that the transmission range can be adjusted based on the emission of at least one, in particular, wireless communication signal (e.g. with a resolution of at least one meter). In this way, it is possible to take influences from the environment (walls, obstacles) into account during installation and to adjust the transmission range depending on this. This also makes it possible to reduce the frequency of false alarms, since in particular the communication between system-limiting radio units and portable devices of the security system according to the invention can be reduced to the smallest possible communication area and limited to the geographical limitation.

The radio unit can be designed specifically for an indoor or outdoor area of the facility. For example, the radio unit for outdoor use has a water-protected housing.

Furthermore, it is conceivable that the monitoring arrangement has a knowledge base. The knowledge base can include at least one rule according to which a dependency of the activation of the alarm function is defined. It is therefore conceivable that the alarm function is activated upon detection of the geographical limitation being exceeded and/or depending on at least one piece of event information and/or depending on at least one signal from a signal transmitter. For example, the knowledge base includes a data memory in which the at least one rule is stored. If the exceeding of the limit is detected and/or the reception of at least one piece of event information and/or the detection of a signal from a signal transmitter takes place, the rule can be used to determine whether the alarm function is activated. The knowledge base can also be designed to be “learnable”. In other words, by adapting the knowledge base, the activation of the alarm function can be individually adapted in relation to a patient in the inpatient facility or in relation to a portable device. For example, it can be specified whether an alarm function should be activated when a geographical limit is detected. Limit values for body signals, in particular vital parameters of a patient, can also be defined, whereby, depending on the definition, exceeding or falling below a single limit value in particular can result in activation of the alarm function.

A “learning ability” can be understood as the ability to recognize certain behavioral patterns from the person. For example, based on historical data, it is known which event patterns statistically preceded a geographical boundary being exceeded. If e.g. For example, if it is recognized from the historical data that people were frequently at certain locations in the facility before the limit was exceeded, this event pattern can modify the rule so that activation is carried out sooner if the event pattern is present. The event patterns can e.g. B. can be recognized by additional radio units, which are distributed within the facility. These event patterns specific to exceeding the limit (i.e. leaving the facility) can then be stored in the knowledge base become. Furthermore, the event patterns and/or the historical data can also include time information. For example, a rule in the knowledge base can state that approaching the limit at a certain time of day (at night) is more likely to result in the limit being exceeded than at other times of the day. Accordingly, the detection of a portable device or a patient in the inpatient facility approaching the geographical boundary can lead to the alarm function being activated earlier at night than at other times of the day. In other words, detecting the event patterns based on the rules can include prioritizing the position determination and/or the alarm function. The knowledge base can constantly develop through a statistical analysis of the event patterns, i.e. be capable of learning.

The use of a knowledge base also has the advantage that the security 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 as part of the alarm function.

A further advantage within the scope of the invention can be achieved if the monitoring arrangement is designed to automatically adapt and/or expand the at least one rule of the knowledge base depending 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 can be used, such as "contact mats", which can trigger the activation of the alarm function and/or can be used to determine position. For this purpose, these devices can also transmit further event information to the monitoring arrangement.

A further advantage can be achieved within the scope of the invention if the processing component is designed to initiate a transmission of event information to the monitoring arrangement depending on the reception of the preferably wireless communication signal, wherein the monitoring arrangement can be designed 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 to receive, and depending on the receipt of the event information - in particular based on at least one rule of a knowledge base - to activate the alarm function.

The monitoring arrangement can advantageously be designed completely separately from the portable device and/or the 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 can therefore be used over a network such as the Internet. It may also be possible for the monitoring arrangement and/or the processing device to at least partially form part of the portable device.

Accordingly, it may be possible for the definition of the geographical limitation and/or the detection of the exceeding of the limitation to be carried out by the portable device itself, and/or the alarm function to be optionally activated and/or executed by the portable device itself. Accordingly, the portable device can itself make an emergency call when executing the alarm function, for example immediately alerting the emergency services. Alternatively, the portable device may communicate with the monitoring arrangement via a communication network such as the Internet to carry out the definition of the geographical boundary and/or the detection of exceeding the boundary and/or the alarm function outside of the portable device.

It is conceivable that by means of the monitoring arrangement, e.g. B. in the form of a backend IT, the security system according to the invention can also be parameterized if necessary, and further components can be integrated (e.g. temporarily or permanently). Accordingly, the security system can also be expandable, e.g. B. other portable devices and/or radio units.

In addition, it can be advantageous within the scope of the invention that a communication device is provided in order to detect the activation of the alarm function and/or to locate the portable device and/or to make an emergency call when the alarm functions are activated. The communication device is, for example, a portable device such as a mobile phone, especially a smartphone, and/or a computer such as a laptop. The communication device can be designed to use the location to visualize the position of the portable device on a display of the communication device. For this purpose, for example, the location coordinates can be evaluated. It is also possible for the communication device to pass on the position of the portable device to an emergency call (and thus to rescue workers) when the activated alarm function is detected. 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 be able to speak to the person when the alarm function is activated. The activation of the alarm function is detected, for example, by the communication device in that the communication device receives an alarm (data or a message) which is sent by the portable device and/or the monitoring arrangement. The communication device can be in data connection with the transmission arrangement in order to detect activation of the alarm function.

• eine Schnittstelle zu weiteren medizintechnischen Geräten, wie eine FHIR Schnittstelle (Fast Healthcare Interoperability Resources Schnittstelle),
• eine FHIR Schnittstelle, um das Signal von einem medizintechnischen Gerät zu empfangen,
• ein Sensor, um einen Parameter der Person und/oder in der Umgebung des tragbaren Geräts zu erfassen, und vorzugsweise um anhand der Erfassung das Signal zu erzeugen.

It is also optionally conceivable for the monitoring arrangement and/or the portable device to have at least one signal generator in order to activate the alarm function depending on a signal from the signal generator, wherein the at least one signal generator can be designed as at least one of the following:

• an interface to other medical devices, such as an 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 wearable device, and preferably to generate the signal based on the detection.

This enables extensive functional expansion through the addition of medical technology devices. The system according to the invention can experience a significant functional expansion if medical devices can be integrated into the system (e.g. using the FHIR interface). The medical technology devices can then function as signal transmitters (e.g. for critical situations). Location (in-house or outdoor) or certain values of the connected devices can serve as triggers for various types of alarms.

• Bereitstellen einer geografischen Positionsbestimmung durch eine Ortungskomponente eines tragbaren Geräts, um die Position des tragbaren Geräts zu bestimmen,
• Empfangen des Kommunikationssignals durch eine Empfangskomponente des tragbaren Geräts,
• Aktivieren der Positionsbestimmung, durch eine elektronische Verarbeitungskomponente des tragbaren Geräts, in Abhängigkeit von dem Empfangen des Kommunikationssignals, insbesondere um die Positionsbestimmung wiederholt durchzuführen,
• Definieren einer geografischen Begrenzung durch wenigstens eine Überwachungsanordnung,

The invention also relates to a method, in particular for monitoring a stationary facility. It is envisaged that at least the following steps are carried out, preferably one after the other or in any order, although individual steps can also be repeated:

• Sending out a preferably wireless communication signal by at least one radio unit for the stationary device,
• Providing geographic positioning by a tracking component of a portable device to determine the position of the portable device,
• receiving the communication signal by a receiving component of the portable device,
• Activating the position determination by an electronic processing component of the portable device, depending on the reception of the communication signal, in particular in order to carry out the position determination repeatedly,
• Defining a geographical boundary through at least one monitoring arrangement,
• Detecting, by the monitoring arrangement and/or based on the position determination, when the limit is exceeded by the portable device, in order to activate an alarm function depending on the detection of the exceeding, which includes the (in particular repeated) locating of the portable device by means of the position determination .

The method according to the invention therefore brings with it the same advantages as have been described in detail with reference to a security system according to the invention. In addition, the method can be suitable for operating a security system according to the invention.

Further advantages, features and details of the invention emerge from the following description, in which reference is made to the drawings Embodiments of the invention are described in detail. The features mentioned in the claims and in the description can be essential to the invention individually or in any combination. Show it:

In the following figures, identical reference numerals are used for the same technical features of different exemplary embodiments.

In Figure 1 a security system 1 according to the invention for a stationary device 2 is shown. The security system 1 has a plurality of radio units 10 for the stationary device 2 for sending 301 a radio signal 210, with a radio unit 10 being configured at an output of the stationary device as a system-limiting radio unit 10.1. Furthermore, at least one portable device 100 is provided for a person 3 of the stationary device 2, which is shown schematically in the figure by way of example in an additional, enlarged representation. The portable device 100 can therefore have a location component 110 for determining the geographical position 305 of the device 100, a transmitting component 115 for sending out 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 Signal generator 130 and a receiving component 120 for receiving 302 of the communication signal 210 and an electronic processing component 140, the latter in order to activate the position determination 305 depending on the reception 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 locating component 110. For this purpose, at least some of, preferably all, components 110, 115, 120, 125, 130, 135, 140, 145 can be arranged together on a printed circuit board and each have at least one integrated circuit.

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

The location component 110 of the portable device 100 can be designed to determine at least one geographical location coordinate for position determination 305, through which the position of the portable device 100 is indicated. It is also possible for the monitoring arrangement 20 to comprise at least one processing device 30 in order to provide at least one geographical boundary coordinate for defining the geographical boundary 200, and in order to assign the at least one boundary coordinate with the at least one determined location coordinate for detecting 312 the exceeding of the boundary 200 compare. This enables the provision of a so-called geofence function.

Furthermore, the monitoring arrangement 20 and the portable device 100 can each have a communication interface 150, preferably a mobile radio interface and/or Internet interface and/or network interface, in order 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.

It is also possible for the monitoring arrangement 20 to have a knowledge base 90, which includes at least one rule according to which the activation of the alarm function depends on the detection 312 of exceeding the limit 200 and/or on at least one piece of event information and/or on a signal a signal generator 130 is defined. The monitoring arrangement 20 can be designed to implement at least one rule of the knowledge base 90 depending on historical data, in particular to automatically adapt and/or expand past activations of the alarm function.

It is also possible for a communication device 80 to be provided in order 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 can furthermore have at least one signal generator 130 in order to activate the alarm function depending on a signal from the signal generator 130.

In Figure 1 An exemplary arrangement of the security system according to the invention in a device 2 is also shown. It can be seen that a person 3 can enter the ground floor, for example coming from a staircase. It is assumed that the person 3 carries a suitable portable device 100 that is capable of recognizing the radio units 10 mounted in the device. If the person 3, for example, initially moves 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 enters into communication with the system-limiting radio unit 10.1. If the person 3 then moves in the direction of the elevators and thus out of the range of the communication signal 210 of the system-limiting radio unit 10.1 and is instead within the range of a non-system-limiting radio unit 10, a position determination 305 activated by the portable device 100 (e.g. GPS functionality ) can be switched off or deactivated again after a certain period of time.

However, if the person 3 leaves the device 2 and exceeds the limit 200 (geofence), the alarm function can be activated, in particular 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, and e.g. B. an emergency call signal can be sent to the communication device 80 or (according to a configuration) directly to a defined address of, for example, rescue workers. The radio units 10 can be attached to suitable locations outdoors and/or indoors to ensure that the position determination 305 remains active.

In Figure 2 A method according to the invention is visualized as an example. First, a communication signal 210 is sent out 301 by at least one radio unit 10 for the stationary device 2. A geographical position determination 305 can then be provided by a location component 110 of a portable device 100 in order to determine the position of the portable device 100. Furthermore, receiving 302 of the communication signal 210 by a receiving component 120 of the portable device 100 may be provided. In addition, position determination 305 can be activated by an electronic processing component 140 of the portable device 100, depending on the reception 302 of the communication signal 210. In addition, a geographical boundary 200 can be defined 311 by at least one monitoring arrangement 20, and detection 312 , by the monitoring arrangement 20 and based on the position determination 305, if the limit 200 is exceeded by the portable device 100, in order to activate an alarm function depending on the detection 312 of the exceedance, which includes the location of the portable device 100 by means of the position determination 305 .

The above explanation of the embodiments describes the present invention solely in terms of examples. Of course, individual features of the embodiments can, if technically sensible, be freely combined with one another without departing from the scope of the present invention.
