Definitions

  • the present invention relates to a system and method for environmental monitoring and automated alerting of a user. More particularly, the invention relates to a system comprising at least one communication network, first communication terminals and second communication terminals and a central unit with memory means, wherein by at least one of the first communication terminals audio and / or video signals can be detected and transmitted together with identification data of the communication terminal to the central unit.
  • a first baby monitor is placed in the room of the baby or the small children, with sounds in the room, so in particular a screaming of the children detected by the baby monitor, are transmitted via a wireless radio connection to a second baby monitor and audibly reproduced by this second baby monitor.
  • Parents or caregivers of the children can stay with this second baby monitor in another room, for example in a study, while still watching any sounds in the room of the baby or the little children.
  • a disadvantage of the baby monitor is that the noise from the caregiver must be constantly monitored and assessed. It is also a disadvantage that the range of the baby monitor is often only a few hundred meters and thus often only suitable for monitoring within a house.
  • other sounds such as noise when breaking glass, opening doors, getting in water, or burning a fire.
  • a reception interface for the reception of by the first communication terminals audio and / or video signals transmitted to the central unit comprises that the central unit has an analysis module for comparing the transmitted audio and / or video signals with the stored reference data of the first look-up table and to Selection of reference data includes, and that the central unit comprises a transmission interface for the transmission of one or more selected reference data associated notification messages to a second communication terminal.
  • Such a system has the particular advantage that, for the analysis of audio and / or video signals in a central processing unit, a high computing power, and with it a high degree of accuracy in the analysis of audio and / or video signals, can be made available at low cost. It is further an advantage that in the central unit a large catalog with reference data of audio and / or video patterns can be collected. This in turn results in a significant improvement in the accuracy of the comparison of audio and / or video signals with stored reference data.
  • a notification message for example, as a synchronous message, such as a call to the second communication terminal and transmitting a voice message, or as an asynchronous message, such as an SMS message (SMS: Short Message Service), be configured.
  • identification data of first communication terminals and identification data of second communication terminals are stored in association with one another on a second lookup table of the storage means.
  • Identification data from first communication terminals can be received by means of the reception interface of the central unit.
  • the central unit comprises a module for comparing the transmitted identification data with stored identification data of the second lookup table and for selecting stored identification data.
  • notification messages can be transmitted to second communication terminals which can be assigned to one or more of the selected identification data.
  • a landline telephone of a user may be provided as a first communication terminal and a mobile telephone of the user as a second communication terminal.
  • the central unit For example, before the user leaves his apartment, he prepares the landline phone for the transmission of audio data to the central unit, for example by means of a call to a definable service number. Subsequently, the user registers his mobile telephone as the second communication terminal assigned to the landline telephone, for example by transmitting a corresponding USSD message (USSD: Unstructured Supplementary Service Data) to the central unit.
  • USSD Unstructured Supplementary Service Data
  • the user may define reference data of audio signals, such as baby crying reference data, glass splintering reference data, or any other reference data.
  • a notification message is transmitted by means of the central unit to the mobile telephone of the user.
  • notification messages and identification data of second communication terminals are stored in association with one another on a third lookup table of the storage means.
  • the central unit comprises a module for comparison of a notification message associated with the selected reference data with stored notification messages and for selection of stored notification messages.
  • notification messages can be transmitted to one or more second communication terminals assigned to the selected notification messages.
  • Such an embodiment variant has the particular advantage that the transmission of a notification message according to the content of the notification message to a second communication terminal is transferable. For example, if the notification message may be associated with events such as burglary, fire, or flooding, it may be useful to notify the public of such public service as the police or the fire department, in addition to notifying the user.
  • the central unit comprises means for storing audio and / or video signals and means for transmission of audio and / or video signals to the at least second communication terminal.
  • the at least second communication terminal comprises means for reproducing audio and / or video signals.
  • the system comprises means for a user-controlled reproduction of audio and / or video signals stored on the central unit.
  • a system has the advantage that the user can play back audio and / or video signals which have led to the notification message as often as desired or that the user can reproduce the audio and / or video signals currently detected by the central unit.
  • the means for analyzing audio and / or video signals are designed for the analysis of a single audio and / or video signal or for the analysis of a plurality of audio and / or video signals.
  • a system which is designed for the analysis of a single audio and / or video signal has the particular advantage that an analysis of the audio and / or video signal is particularly efficient feasible.
  • a system designed for the analysis of a plurality of audio and / or video signals has the particular advantage that the comparison of audio and / or video signals with reference data of the first look-up table based on audio and / or video signals from different locations and / or perspectives. For example, when monitoring babies, it is possible to monitor both audio signals in the baby's room and audio signals in another room with a caregiver. The analysis of these audio signals can then be set up, for example, such that a notification message is only triggered if the audio signals in the baby's room indicate a crying of the babies and the audio signals in the room of the caregiver indicate that the caregiver is asleep.
  • the system comprises means for the dynamic configuration of the analysis of audio and / or video signals.
  • a dynamic configuration of the analysis of audio and / or video signals may relate, for example, to a time of day, to a date, to a user profile of the second communication terminal or to a location of the second communication terminal.
  • the second communication terminal may also relate to a mobile terminal, wherein the current user profile and / or the current location of the mobile terminal by means of a profile module and / or a location module, for example according to a triangulation measurement of base stations of the mobile network or according to a measurement of a GPS module (GPS: Global Positioning System) transmitted to the central unit.
