  • Automatic alarm detection systems with a decentralized alarm detection unit in the form of a so-called automatic dialing and announcement hazard detector according to the VDE 0820 standard and with an alarm center are already known for monitoring objects.
  • Such automatic dialing and announcement hazard detectors are connected to various monitoring contacts or signaling contacts for the detection of assigned alarms on the object and are connected directly to the public telephone network.
  • these object-side alarm recording units select a stored number in the event of an alarm and, after the dial-up connection to the alarm center has been established, report a stored text to the security staff at the location of the alarm center, for example the location of the alarm knows.
  • an automatic dialing and announcement hazard detector of a more recent design fails to establish a connection to the alarm center even after several attempts, the hazard detector dials an alternative number in order to attempt to carry out the same procedure. Due to the long dialing times for several attempts, this form of connection establishment is unacceptable for objects that are classified as worthy of protection. For this reason, automatic dialing and announcement hazard detectors are only accepted by the association of property insurers for objects of low hazard class.
  • an ISDN connection is established by an exchange of information packets between the calling subscriber and the ISDN network and between the ISDN network and the Addressees or called participants set up.
  • These information packages are defined in international standards, such as ITU (CCITT) Q. 930-Q.940 "Digital Subscriber Signaling". These standards describe the individual data packets and how they can be used.

  • the most important field which is best known from telephony, is the "Calling Party Number” field, which is known to users of ISDN telephones by the "Suppress phone number” function and by the "List call” function in private branch exchanges.
  • This "set up” packet is transmitted by the network, for example Weg, to the number specified in the "set up” packet.
  • the recipient With the first incoming signaling packet, the recipient receives information about the type of call and, insofar as the relevant field is filled, also information about the calling person.
  • a method for monitoring an object with a decentralized alarm detection unit assigned to the object and with an alarm center is such that a safe and fast Transmission of the alarm information in the event of an alarm is made possible without the need for a dedicated line between the alarm detection unit and the alarm center.
  • information transmitted via the signaling channel which uniquely identifies the decentralized alarm detection unit and which is preferably formed by the call number of the alarm detection unit (Calling Party Number), is used to trigger the alarm Information used for the control center, so that the alarm triggering before the connection with the necessity of Access to the message / data channel or B channel takes place.
  • the call number transmitted in the D channel of the alarm recording unit serves as alarm information.
  • the transmitted number represents a clear criterion for identifying the decentralized alarm detection unit, which does not require any additional encryption, since ISDN connections, like all communication connections, are connection-oriented, i.e. a falsification of the addressee or the sender automatically leads to no connections.
  • the step of detecting the alarm state based on the transmission of the information which uniquely identifies the decentralized alarm recording unit, preferably the call number of the decentralized alarm recording unit, is followed by the step of establishing a connection via the message / data channel of the digital data network, if this channel is free is.
  • This procedure corresponds to the establishment of a "normal" telephone connection, ie the standard signaling of an ISDN call is carried out with a free B channel of the ISDN network. For example, the situation can now arise that the message / data channel of the connection of the alarm center to the ISDN network is occupied by various alarm recording units due to a large number of alarm messages arriving at the same time.
  • Such an exceptional case can occur, for example, during a thunderstorm, in which a large number of alarm detection devices for monitoring houses erroneously detect an intrusion situation. If the B channels are already occupied by such a natural event due to the large number of alarms arriving almost simultaneously, only the call is acknowledged and rejected, but the call number of the respective alarm recording units, i.e. the call number identification or the calling party number in the alarm center is saved.
  • the method according to the invention ensures a more reliable alarming compared to the conventional, connection-oriented alarming, which achieves the same alarming effect only when using a very large number of user channels, which essentially corresponds to the number of possible alarm sources, but with a considerable technical outlay and therefore corresponding additional costs are required.
  • the incoming alarm messages can be used for the cartographic position display of the alarm location, so that trained personnel can distinguish false alarms caused by a thunderstorm from real alarms, for example.
  • the staff in the alarm center can, for example, switch an audio-video connection via the digital network and check the object.
  • the decentralized alarm detection unit can recognize the alarm center based on the call number of the alarm center and, in the event of an alarm, reject any other call with the exception of the call to the alarm center, so that the line cannot be blocked.
  • the alarm center has no knowledge of whether the connection of the alarm center to a decentralized alarm detection unit via the digital data network has been interrupted or persisted, and furthermore no knowledge of whether the decentralized alarm detection unit is active, defective or switched off.
  • the present invention has for its object to provide a method for monitoring an object with a decentralized alarm detection unit assigned to the object and with an alarm center such that a safe and fast Transmission of the alarm information in the event of an alarm is made possible without the need for a dedicated line between the alarm detection unit and the alarm center, in which it is possible for the alarm center to gain knowledge of the status of decentralized alarm detection units or of the connection status to decentralized alarm detection units via the digital network .
  • the invention provides a method for monitoring an object with a decentralized alarm detection unit assigned to the object and with an alarm center which are connected to one another via a digital data network with a signaling channel and a message / data channel, with the following method steps:
  • the alarm center stores the information which uniquely identifies the alarm detection unit and generates an alarm display indicating the alarm detection unit;
  • the present invention provides a method for monitoring one or a plurality of objects by means of the decentralized detection units assigned to the object and at least one alarm center, whereby the cyclical transmission of test information from the respective decentralized detection units to the alarm center always gives the alarm center knowledge of the state of the individual detection units or the state of the digital network.
  • This represents a considerable increase in security compared to the method described in the main patent, since the alarm center immediately gains knowledge of the failure of, for example, a security system, which is the decentralized detection device, and suitable countermeasures can be taken if necessary.
  • the test information is transmitted over the signaling channel during signaling gaps.
  • the transmission via the D channel thereof takes place using the so-called X25 service. This is an inexpensive way to transfer the test information.
  • the following description of the preferred exemplary embodiment of the method relates to its use in the case of the ISDN network as a digital data network.
  • Any digital data network that uses a signaling channel or Control channel and a message / data channel can be used instead of the ISDN network.

  • the alarm detection unit can be a PC at the location of the object to be monitored, which is provided with a plurality of alarm sensors and is connected to the ISDN network. If the alarm detection unit detects the occurrence of this alarm in step 2, the program proceeds to step 3.
  • the alarm detection unit prepares the data to be transmitted including the calling party number and copies this data into the UUS frame, i.e. the field for data transmission from user to user via the signaling channel.
  • the data to be transmitted can be, for example, a characterization of the type of alarm, such as the response of a glass break sensor, the response of a fire sensor or the like.
  • the information built up in the UUS frame is transmitted from the alarm detection unit to an alarm center via the signaling channel or D channel of the ISDN network.
  • step 5 the alarm center checks whether the number of the alarm recording unit transmitted via the signaling channel is known, that is to say, for example, it is contained in a table of the number of participants in the alarm system. If this is not the case, the method proceeds to step 6, in which the call is rejected. If the check at step 5 shows that the number of the alarm detection unit is one of those in a If the table of the alarm center contains telephone numbers, the method continues at step 7, in which the alarm data, namely at least the telephone number of the calling alarm recording unit, possibly the transmitted alarm type and, for example, the current time are stored.

  • the alarm is triggered before the connection described below is established with access to the message / data channel.
  • step 10 the alarm center checks whether the message / data channel or B channel of its connection to the ISDN network is free. If this is the case, the method continues with step 13. Otherwise, the method proceeds to step 11, in which the alarm center receives the receipt via the signaling channel or D-channel of the ISDN network in the case of the so-called "release complete", that is to say the termination procedure for the connection setup which has not been established via the signaling channel the alarm message is confirmed.
  • this step 11 can in turn include the preparation of the data to be retransmitted, namely the reconfirmation, the copying of the data to be retransmitted into the UUS frame for ISDN and the subsequent transmission of the UUS frame pages of the alarm center via the signaling channel.

  • optical and / or acoustic data are transmitted from the alarm detection unit to the alarm center or to said other center via the message / data channel or B channel in the following method step 14 in order to determine the cause of the alarm check and in order to enable the personnel in the alarm center to take appropriate further measures, e.g. to notify the police, fire service, emergency services, etc.
  • an audio-video connection can be established between the alarm detection unit and the alarm center.
  • the establishment of the connection of the message / data channel or B-channel in ISDN is terminated and the connection is thus terminated.
  • the method ends in the following method step 16.
  • Steps 3 to 15 of the process sequence described are preferably repeated until the occurrence of the alarm has been transmitted from the alarm recording unit to the alarm center and the alarm center transmits the alarm either by reconfirmation via the signaling channel in step 11 or by establishing a connection via the message / Data channel confirmed at step 13.
  • the method described above relates generally to an alarm case of a decentralized detection unit and also offers continuous monitoring of the status of the terminals, ie the decentralized detection units, regardless of the alarm case.
  • test signals are transmitted cyclically by the X25 service from a decentralized alarm detection unit to the alarm center. If the alarm center detects each of these test signals from a specific alarm detection unit, it knows that this alarm detection unit is active, ie switched on and not defective and properly connected to the digital network. In the event of an intentional shutdown of the alarm detection unit, the alarm center is preferably informed of this shutdown in order not to cause any wrong activities upon the subsequent failure to receive the test signals from this alarm detection unit.
  • the signaling / control channel additionally contains the possibility of a very slow but also very inexpensive data channel in the signaling gaps, these are offered very cheaply by the network operators.
  • Such a transmission is offered as an X25 service in the ISDN network.
  • a network of intelligent terminals can be interconnected to form an alarm network in such a way that information about the status of the individual terminals, i.e. Alarm detection units, to the control center, i.e. the alarm center, as well as between the individual devices. It is thus advantageously possible to use the packet data traffic to set up both a sabotage protection and also a load distribution mechanism. This can be achieved by a signaling chain as well as a star network.
