Definitions

  • the method according to the invention relates to better ones Exploitation of the information content when processing messages of alarm messages.
  • the aim of the invention Solution is due to more sophisticated Information on the reason for the trigger also in the choice of intervention measures to be able to proceed in a more differentiated manner.
  • alarm messages that were not triggered due to minor events is reacted with excessive measures.
  • an alarm system consists of an alarm center with transmission devices, which is usually located in the object to be monitored or in the security area to be monitored. Detectors or zones with individual detectors are connected to the alarm center. Individual detectors can be designed, for example, as motion detectors, window contacts or similar sensors.
  • VdS Association of Non-Life Insurers.
  • the transmission of a message (e.g. intrusion) from the Alarm center to the alarm receiving center is by the Transmission protocol regulated. It is widespread so-called Telim protocol, in which usually through existing hardware conditions only 8 instead of the possible 16 zones of the protocol frame are occupied.
  • the technical problem of the method according to the invention is based on the full utilization of the Information content of the known transmission protocols, in particular the standard Telim transmission protocol or the VdS 2465 / ISDN transmission protocol, for the complex Monitoring of security areas with automatic Message processing in an alarm receiving center aligned.
  • the invention No solution provided.
  • the method according to the invention is explained in more detail below on the basis of the usual Telim transmission protocol.
  • the VdS 2465 ISDN transmission protocol is used analogously.
  • the reason for the alarm is decisive for the execution of the agreed intervention measure.
  • the "alarm" occasion / signal type requires a different intervention measure than the "technical error" occasion / signal type.
  • the reason for a transmission to the alarm receiving point is that one of the detectors or one of the detection groups triggers due to an external influence (alarm reason).
  • Which detector or message group first recognized an event or reason for the alarm is transmitted in Telim word 7 "triggering group".
  • the triggering group is assigned the respective signal type.
  • alarm systems with (in-house) radio detectors there is also the possibility of signaling a defective or sabotaged detector to a permanently manned alarm receiving point.
  • the signal type is added to the criteria and triggering group for each detector in the triggered zone a criterion called detector value is recorded, which indicates the activation status ON / OFF of the respective detector at the end one due to local conditions specified pre-alarm time.
  • the collective message contains information on the signal type, the triggering group and the detector value.
  • the detector value indicates the ON / OFF states of the individual detectors of the detector group / groups triggered within the pre-alarm time.
  • the collective message is evaluated by computing. Based on the criteria signal type, triggering alarm group, detector value which are in the correct order for all alarms / alarm groups triggered during the pre-alarm period, a mathematical reference is made to the stored specific local conditions of the security area to be monitored. If, for example, all detectors who have given a report due to a break-in are related to the local conditions that are assumed to be known, a statement can be made as to which route an intruder traveled in the security area during the pre-alarm time. This is how the first triggered detector designates the place where the intruder enters. Its further path can be recognized, for example, by the fact that successively several motion detectors are triggered that the intruder has passed. By evaluating the entirety of the information received in relation to its causal relationship, a computational statement is made regarding the state of the triggered alarm group (s). The status of the reporting group (s) and the intervention measures ordered according to priorities for this specific status are displayed.
  • a security area to be monitored is monitored by at least two zones. For example, contact or motion detectors are assigned to each zone.
  • An alarm center is installed in the object or in the security area to be monitored, in which all incoming alarm messages appear.
  • the alarm messages are summarized by this alarm center and transmitted to an alarm receiving point.
  • messages that belong to the alarm center itself have no detector reference.
  • the bits of the Telim words 8 and 9 all have the value 0. Such a procedure is considered effective since the resources of the message groups are not required for this.
  • Detection groups in which several detectors one Detection groups must be individually identifiable (individual detector identification), can the Telim word "triggering group" interpreted in such a way that it names the person who which is triggered first within a zone Has.
  • the Telim words 8 and 9 then refer to the other detectors in the same zone.
  • This variant assumes a modification of the software within the Alarm center with the aim of individual detector identification.
  • the security area to be monitored is controlled by an external sharp system with alarm center and several to the Alarm center connected to monitored zones.
  • the alarm system is in operation. It can send messages to a Set the alarm receiving point down.
  • the transmission to the alarm receiving center is based on the Telim transmission protocol.
  • the method according to the invention is particularly suitable for Transmission of alarm messages based on the Telim transmission protocol or the VdS 2465 ISDN transmission protocol based. It is the same for other transmission protocols apply.

  1. Dispositif ayant pour objectif d'obtenir une meilleure différentiation lors du traitement des messages d'alarme, pour lequel une zone de sécurité est surveillée par plusieurs, et au minimum deux groupes de détecteurs, chaque groupe de détecteurs étant composé de plusieurs détecteurs individuels prévus pour indiquer différentes causes d'alarmes/différents types de signaux, conçu de tel façon qu'après le déclenchement d'au moins un groupe de détecteurs, toutes les alarmes individuelles entrantes dans une période de pré-alarme librement définissable sont rassemblées en fonction de leur ordre d'entrée dans un message centralisé avec indication du type de signal et du groupe de détecteurs déclenchant, caractérisé en ce que,
    en plus des critères "type de signal" et "groupe de détecteurs déclenchant", un critère désigné avec une valeur de détecteur est saisi pour chaque détecteur du ou des groupes de détecteurs déclenchants, qui indique l'état d'activation MARCHE/ARRÊT de chacun des détecteurs par rapport au type de signal déclenché à la fin d'une période de pré-alarme, en ce que tous les messages du ou des groupes de détecteurs déclenchés qui sont arrivés pendant la période de pré-alarme sont réunis selon leur ordre d'entrée en un message d'alarme centralisé avec les critères "type de signal", "groupe d'alarme déclenchant" et "valeur de détecteur" et transmis à un poste de réception des alarmes, en ce que, dans le poste de réception des alarmes les critères "type de signal", "groupe de détecteurs déclenchant" et "valeur de détecteur" sont analysés pour chaque groupe de détecteurs déclenché, en ce que, à partir de la totalité des informations reçues, l'état du ou des groupes de détecteurs déclenchés est déduit par calcul, et en ce que sont indiqués l'état du ou des groupes de détecteurs déclenchés ainsi que les mesures d'intervention pour cet état, classées par priorité.
