Definitions

  • Alarm communication system including one or more alarm transmitters with call function which are in connection with one or more alarm objects which shall be monitored by an alarm receiver via a telecommunication network, at which each alarm transmitter is assigned a subscriber number.
  • Telia Number Presentation With Telia Number Presentation and a telephone, or additional unit with display, one can see from which telephone number a call is coming even before one answers. One also can see who has/have called while one has been not at home.
  • Number Presentation In order to utilize the service Number Presentation, one needs an additional unit or a special telephone with built in additional unit. On that additional unit (box) one can read date, definite time and telephone number. And whether the telephone number is unknown or unlisted ("protected"). Number Presentation consequently is a well known concept .
  • the alarm systems which are constructed in such a way that an alarm signal shall be transmitted via the telecommunication network, via a called circuit connection, to a device which receives the alarm signal and after that to a person or equipment which receives and takes measures regarding the cause of the alarm, have certain disadvantages .
  • an alarm communication system which gives a higher security to the one who is owner of the alarm.
  • the alarm owner can with greater security trust his/her alarm when he/she knows that the probability for the alarm being reached the receiver increases.
  • the solution also implies that one will have a comparatively simple system which results in that alarm also is triggered off when the alarm transmitter for some reason has become defective.
  • Another advantage is that one by the invention will have an alarm system with two functions.
  • the alarm system on one hand monitors that the alarm system all the way from the alarm transmitter to the place of monitoring is faultless and that the alarm object is in wanted state.
  • only an intermittent and moderate increase of load obtained in the network DESCRIPTION OF FIGURES
  • figure 1 a basic drawing of the alarm communication system according to the invention is shown.
  • FIG 1 a basic drawing over the alarm communication system according to the invention is shown where an alarm transmitter 1 is connected to an alarm device 2 and a telecommunication network 3, and further via the telephone connection of the place of reception to the place of reception for number presentation 4 which is in connection with one or more alarm centra 5.
  • the alarm transmitter 1 consists of a calling alarm transmitter which is connected to an object which shall be monitored.
  • the alarm transmitter in certain cases can consist of two parts, namely one at the alarm object existing alarm transmitter which is completed with a special calling alarm transmitter which are connected to the same telephone.
  • the alarm transmitter can be connected, in known way, to the alarm object which can consist of a part in a process industry which needs to be monitored, or a part in a villa which needs monitoring or the like.
  • the alarm transmitter also can be connected to a moving object such as, for instance, a car, or to a person.
  • the alarm transmitter as such is of the type which calls one in advance programmed telephone number. It is set to call this number at certain time intervals, for instance every 3 minutes. When the alarm transmitter shall make a "monitoring call", this is made in normal way to the place of reception 4.
  • the signal then will pass via the public network which consists of both the fixed and the mobile telecommunication network to the receiver equipment of the place of reception for reception of number presentation.
  • the place of reception 4 has a computer which registers the "monitoring calls”.
  • This computer is programmed to, on basis of the subscriber number which is represented at the "monitoring calls” which are repeated at a certain interval which is in accordance with the interval to which the call function of the alarm transmitter is set, register this as the alarm transmitter and the telecommunication network, from the alarm transmitter to the alarm centre, being faultless. In those cases when the "monitoring calls” do not occur when they should be received, at the preset time interval, the computer transmits a network error alarm to the alarm centre 5, for measures to be taken.
  • the computer When the computer registers the incoming "monitoring calls", the call is not answered, but there only is made a registration of the telephone number to which the alarm transmitter is connected. This results in that no telephone charge is debited for the monitoring.
  • the basic principle consequently is that the telecommunication network will be monitored by continuous calls. The intervals at which the calls are made depends on how important it is to have safe monitoring of a certain object. In the cases the alarm object needs a more thorough monitoring during the night, then the interval of the calling is set to a a shorter time during the night. A corresponding measure also is taken with the computer at the place of reception 4 which is expected to be called.
  • the setting of time interval to a higher frequency at night and a lower frequency at daytime also means that the telecommunication network will be less loaded during daytime when the load of telecommunication traffic normally is higher.
  • the alarm transmitter is, as has been mentioned, connected to the public telecommunication network and can communicate with this both via a fixed connection to the network and via the mobile cellular telecommunication network.
  • the previosly mentioned alarm centre in corresponding way can communicate in these two ways.
  • mobile telephone equipment is connected to the alarm transmitter which in conventional way transmits to the receiver.
  • an alarm centre with alarm receiver can receive telephone signals from a nearby base station.
  • the number presentation equiment then can consist of a portable mobile telephone where the signals which are represented by the telephone number are directly transmitted to the alarm receiver for registration of which subscriber number that is calling.
  • the setting of interval time can be made directly by setting of time information with conventional technology at the alarm transmitter.
  • the setting of corresponding time at the alarm centre can be made via
  • the alarm owner has possibility to set the interval time of the calling device directly from own computer located at the alarm owner's. By that the alarm owner himelf/herself can set the time interval for calling.
  • the invention is not restricted to the above presented, but can be modified in different ways within what is defined in the patent claims.
  • the invention also can be used in the opposite direction, i.e. that the alarm transmitter is called. This will increase the security against exchange of alarm transmitter for false alarm transmitter. Absence of "monitoring call" to the alarm transmitter then can be indicated locally m the monitored object .

Abstract

L'invention concerne un système de transmission d'alarme comprenant un ou plusieurs transmetteurs (1) de signal d'alarme dotés de fonctions d'appel, qui sont connectés à un ou plusieurs objets (2) sous alarme et sont contrôlés par une ou plusieurs centrales d'alarme via un réseau de télécommunications, un numéro d'abonné étant attribué à chaque transmetteur de signal d'alarme. La centrale (5) d'alarme est connectée à un lieu de réception de présentation (4) de numéro, qui transmet une alarme de réseau aux centrales d'alarme si les 'appels de contrôle' réguliers sont interrompus.
