Definitions
- the invention relates to an intrusion detection system with a control center and intrusion detectors connected to it.
- Intrusion detection systems are used for intrusion protection, in which the individual intrusion detectors or detectors are connected to a control center via a monitored two-wire line.
- windows and doors in particular are monitored.
- relatively simple intrusion detectors are arranged on the doors and on the windows, for example bolt and magnetic contacts. Some of these can be equipped with their own evaluation electronics.
- each individual detector or detector is connected to the control center via a two-wire line. This requires a lot of assembly work, especially if a large window front with many single sashes has to be monitored.
- the object of the invention is therefore to avoid these disadvantages mentioned above and to take measures which allow the burglar detectors to be easily installed in a burglar alarm system.
- At least one communication unit which is connected to the center via a signaling line, is arranged at a central point in the respective monitoring room, that the communication unit has a transmitting and receiving device that transmits all around, that each of the doors and / Intrusion detectors or windows arranged have a transmitting and receiving device, an energy converter and an energy store, and that the individual intrusion detectors can be connected wirelessly to the communication unit.
- Such an arrangement has the advantage that the two-wire line from the control center to the communication unit only needs to be routed to a room to be monitored, for example in the middle of the ceiling.
- Each individual intrusion detector or intrusion detector is self-sufficient and is connected to the communication unit via a wireless connection.
- a capacitor or a backup battery can expediently be provided as the energy store.
- An electromagnetic or piezoceramic converter can be provided as the energy converter, which itself obtains the energy required from the state to be monitored, as is the case when the windows or doors are opened and closed. It is particularly advantageous to use one or more photoelectric energy converters, e.g. To provide solar elements that derive the required energy from the ambient light.
- a radio connection can be provided for the wireless transmission of information between the intrusion detectors and the communication unit, but this is not always advantageous due to the required channels and susceptibility to interference within buildings. It has proven particularly expedient to provide ultrasound transmitters and receivers or infrared transmitters and receivers for the transmitting and receiving devices. It is particularly advantageous to provide several transmitting and several receiving diodes for each intrusion detector, so that safe and reliable transmission is ensured. If, for example, a transmitting or receiving diode of the intrusion detector is covered, for example by a fly sitting on it, the transmission is nevertheless guaranteed. Likewise, the failure of a transmitting or receiving electrode would not yet lead to the failure of the transmission between the intrusion detector and the communication unit.
- the communication unit which is arranged at the central point of the room to be monitored, expediently has a row of transmitting and receiving diodes arranged radially, which illuminate all around the room, so that no special alignment between the individual detectors and the communication unit is required. It can also be useful if the space is there require the provision of several communication units in one room.
- each transmitting and receiving device of the intrusion detector can have an adjustable address, so that the individual detectors can be queried in a targeted manner from the control center or the alarm-emitting, i.e. emitting a pulse, detector can be identified in the control center .
- the individual detectors are switched to what is known as a “closure line”; this is especially so as to avoid false alarms. This means that the individual detectors are only queried at the moment of arming to ensure that all safety devices are effective. If a window or a door is now opened in the armed state, the intrusion detector in question emits one or more pulses wirelessly to the communication unit via its transmitting device. From there, this alarm message is wired to the control center.
- Fig. 1 burglar detectors D are arranged on the two window fronts shown (wall M, window F, pillar SP, window, etc.), which are connected wirelessly to the communication unit KE arranged in the middle of the room, generally on the ceiling stand.
- This communication unit KE is wired (ML) to the center Z.
- the intrusion detectors D via their solar elements SE, collect the energy from the ambient light, which they store, for example, in a buffer battery PB, which supplies the intrusion detector D with the energy required for the evaluation electronics and for the transmission of transmission signals.
- the communication unit KE has all around, that is to say radial, a series of infrared transmitting and receiving diodes SE, ED, each of which has overlapping radiation lobes and thus irradiates the room all around.
- a separate alignment of the intrusion detectors D on the communication unit KE is not necessary (Fig.2).
- FIG. 3 shows the basic arrangement of an intrusion detector D, which has, for example, a magnetic contact MK which is connected to the evaluation electronics AWE.
- the intrusion detector D has an infrared receiving diode ED and at least one infrared transmitting diode SD. Furthermore, the intrusion detector D has solar elements SE, which extract the energy from the ambient light and convert it into electrical energy, and which is stored in a corresponding energy store PB for supplying the evaluation electronics and the infrared transmitter and receiver diodes connected to it.
- Fig. 4 shows the possible design of a burglar detector D according to the invention with a series of solar elements SE, here with only one infrared receiving diode, which, however, has a collecting optics SO, which is very wide, so that the infrared signals are received reliably from the communication unit KE is enabled.
- the intrusion detector also has two transmission diodes SD.
- the intruder alarm system can also be used for fire monitoring if IR light is used for the transmission link. If the transmission path is regularly monitored for functionality by generating and checking IR light pulses from the individual detectors to the communication unit, the communication unit can also check whether a certain light attenuation has occurred. A fire alarm can be derived if the damping can be specified.
Abstract
Description
Die Erfindung bezieht sich auf eine Einbruchmeldeanlage mit einer Zentrale und daran angeschlossenen Einbruchdetektoren.The invention relates to an intrusion detection system with a control center and intrusion detectors connected to it.
Für den Intrusionsschutz werden Einbruchmeldeanlage verwendet, bei der die einzelnen Einbruchmelder bzw. Detektoren über eine überwachte Zweidrahtleitung mit einer Zentrale verbunden sind. Zum Schutz der Außenhaut werden insbesondere Fenster und Türen überwacht. Dazu sind an den Türen und an den Fenstern relativ einfache Einbruchdetektoren angeordnet, beispielsweise Riegel- und Magnetkontakte. Diese können teilweise mit einer eigenen Auswerteelektronik ausgerüstet sein. In jedem Fall ist jeder einzelne Melder bzw. Detektor über eine Zweidrahtleitung mit der Zentrale verbunden. Dies erfordert einen großen Montageaufwand, insbesondere wenn eine große Fensterfront mit vielen Einzelflügeln zu überwachen ist.Intrusion detection systems are used for intrusion protection, in which the individual intrusion detectors or detectors are connected to a control center via a monitored two-wire line. To protect the outer skin, windows and doors in particular are monitored. For this purpose, relatively simple intrusion detectors are arranged on the doors and on the windows, for example bolt and magnetic contacts. Some of these can be equipped with their own evaluation electronics. In any case, each individual detector or detector is connected to the control center via a two-wire line. This requires a lot of assembly work, especially if a large window front with many single sashes has to be monitored.
Dafür ist die Verlegung von zusätzlichen Kabelkanälen erforderlich. Dies kann sehr aufwendig und kostenintensiv sein, wenn die Gebäude eine Vielzahl von Beton- oder Stahlpfeilern aufweisen. Auch bei historischen Gebäuden ergeben sich große Probleme, denn die Verbindungsleitungen sollen im allgemeinen unsichtbar verlegt sein, was einen hohen Montageaufwand erfordert. Oder es darf an historischen Mauern keine Aufbrucharbeit vorgenommen werden, so daß die Leitungen auf Putz verlegt werden müssen, was jedoch unschön und störend ist.This requires the laying of additional cable ducts. This can be very complex and expensive if the buildings have a large number of concrete or steel pillars. There are also major problems with historic buildings, because the connecting lines should generally be laid out invisibly, which requires a lot of installation work. Or it is not allowed to work on historical walls, so that the lines have to be laid on plaster, which is unpleasant and annoying.
Aufgabe der Erfindung ist es daher, diese obengenannten Nachteile zu vermeiden und Maßnahmen zu treffen, die bei einer Einbruchmeldeanlage eine einfache Montage der Einbruchdetektoren gestattet.The object of the invention is therefore to avoid these disadvantages mentioned above and to take measures which allow the burglar detectors to be easily installed in a burglar alarm system.
Diese Aufgabe wird dadurch gelöst, daß im jeweiligen Überwachungsraum mindestens eine Kommunikationseinheit, die mit der Zentrale über eine Meldeleitung verbunden ist, an zentraler Stelle angeordnet ist, daß die Kommunikationseinheit eine rundum übertragende Sende- und Empfangseinrichtung aufweist, daß jeder der an den Türen und/oder Fenstern angeordneten Einbruchdetektoren eine Sende- und Empfangseinrichtung, einen Energiewandler und einen Energiespeicher aufweist, und daß die einzelnen Einbruchdetektoren mit der Kommunikationseinheit drahtlos verbindbar sind.This object is achieved in that at least one communication unit, which is connected to the center via a signaling line, is arranged at a central point in the respective monitoring room, that the communication unit has a transmitting and receiving device that transmits all around, that each of the doors and / Intrusion detectors or windows arranged have a transmitting and receiving device, an energy converter and an energy store, and that the individual intrusion detectors can be connected wirelessly to the communication unit.
Eine derartige Anordnung hat den Vorteil, daß in einen zu überwachenden Raum lediglich an eine Stelle, beispielsweise in der Mitte der Decke, die Zweidrahtleitung von der Zentrale zur Kommunikationseinheit geführt werden muß. Jeder einzelne Einbruchmelder bzw. Einbruchdetektor ist für sich autark und steht über eine drahtlose Verbindung mit der Kommunikationseinheit in Verbindung.Such an arrangement has the advantage that the two-wire line from the control center to the communication unit only needs to be routed to a room to be monitored, for example in the middle of the ceiling. Each individual intrusion detector or intrusion detector is self-sufficient and is connected to the communication unit via a wireless connection.
Für die Detektoren ist keinerlei Leitungsmontage erforderlich, da diese aus der Umgebung, beispielsweise dem Umgebungslicht, über geeignete Energiewandler ihre Energie gewinnen, die sie dann in einen geeigneten Energiespeicher für die Versorgung der Detektor-Auswerteelektronik benötigen.No line assembly is required for the detectors, since they obtain their energy from the environment, for example the ambient light, via suitable energy converters, which they then need in a suitable energy store for supplying the detector evaluation electronics.
Als Energiespeicher kann zweckmäßigerweise ein Kondensator oder eine Pufferbatterie vorgesehen sein.A capacitor or a backup battery can expediently be provided as the energy store.
Als Energiewandler kann ein elektromagnetischer oder piezokeramischer Wandler vorgesehen sein, der die benötigte Energie aus dem zu überwachenden Zustand selbst gewinnt, wie dies beim Öffnen und Schließen der Fenster oder der Türen der Fall ist. Besonders vorteilhaft ist, einen oder mehrere fotoelektrische Energiewandler, z.B. Solarelemente, vorzusehen, die die benötigte Energie aus dem Umgebungslicht gewinnen.An electromagnetic or piezoceramic converter can be provided as the energy converter, which itself obtains the energy required from the state to be monitored, as is the case when the windows or doors are opened and closed. It is particularly advantageous to use one or more photoelectric energy converters, e.g. To provide solar elements that derive the required energy from the ambient light.
Für die drahtlose Informationsübertragung zwischen den Einbruchdetektoren und der Kommunikationseinheit kann eine Funkverbindung vorgesehen sein, was jedoch aufgrund der benötigten Kanäle und Störanfälligkeit innerhalb von Gebäuden nicht immer vorteilhaft ist. Als besonders zweckmäßig hat es sich erwiesen, für die Sende- und Empfangseinrichtungen Ultraschallsender- und empfänger oder Infrarotsender und -empfänger vorzusehen. Dabei ist es besonders vorteilhaft, bei jedem Einbruchdetektor mehrere Sende- und mehrere Empfangsdioden vorzusehen, damit eine sichere und zuverlässige Übertragung gewährleistet ist. Ist beispielsweise eine Sende- oder Empfangsdiode des Einbruchsmelders abgedeckt, beispielsweise durch eine aufsitzende Fliege, so ist dennoch die Übertragung gewährleistet. Ebenso würde der Ausfall einer Sende- oder Empfangselektrode noch nicht zum Ausfall der Übertragung zwischen dem Einbruchdetektor und der Kommunikationseinheit führen.A radio connection can be provided for the wireless transmission of information between the intrusion detectors and the communication unit, but this is not always advantageous due to the required channels and susceptibility to interference within buildings. It has proven particularly expedient to provide ultrasound transmitters and receivers or infrared transmitters and receivers for the transmitting and receiving devices. It is particularly advantageous to provide several transmitting and several receiving diodes for each intrusion detector, so that safe and reliable transmission is ensured. If, for example, a transmitting or receiving diode of the intrusion detector is covered, for example by a fly sitting on it, the transmission is nevertheless guaranteed. Likewise, the failure of a transmitting or receiving electrode would not yet lead to the failure of the transmission between the intrusion detector and the communication unit.
Die Kommunikationseinheit, die an zentraler Stelle des zu überwachenden Raumes angeordnet ist, weist zweckmäßigerweise radial angeordnet eine Reihe von Sende- und Empfangsdioden auf, die rundum den Raum ausleuchten, so daß keine besondere Ausrichtung zwischen den einzelnen Detektoren und der Kommunikationseinheit erforderlich ist. Ebenso kann es zweckmäßig sein, wenn die Raumverhältnisse es erfordern, in einem Raum mehrere Kommunikationseinheiten vorzusehen.The communication unit, which is arranged at the central point of the room to be monitored, expediently has a row of transmitting and receiving diodes arranged radially, which illuminate all around the room, so that no special alignment between the individual detectors and the communication unit is required. It can also be useful if the space is there require the provision of several communication units in one room.
In Weiterbildung der Erfindung kann jede Sende- und Empfangseinrichtung des Einbruchdetektors eine einstellbare Adresse aufweisen, so daß von der Zentrale her die einzelnen Detektoren über die Kommunikationseinheit gezielt abgefragt werden können bzw. der alarmgebende, also einen Impuls aussendende, Detektor in der Zentrale identifiziert werden kann.In a further development of the invention, each transmitting and receiving device of the intrusion detector can have an adjustable address, so that the individual detectors can be queried in a targeted manner from the control center or the alarm-emitting, i.e. emitting a pulse, detector can be identified in the control center .
In einer zweckmäßigen Ausgestaltung der Erfindung werden die einzelnen Melder auf sogenannte "Verschluß-Linie" geschaltet; dies insbesondere, um Fehlalarme zu vermeiden. Das bedeutet, daß die einzelnen Detektoren nur im Moment des Scharfschaltens abgefragt werden, um sicherzustellen, daß sämtliche Sicherungseinrichtungen wirksam sind. Wird nun im scharfgeschalteten Zustand ein Fenster oder eine Tür geöffnet, so gibt der betreffende Einbruchdetektor über seine Sendeeinrichtung einen oder mehrere Impulse drahtlos zur Kommunikationseinheit ab. Von dort gelangt diese Alarmmeldung drahtgebunden zur Zentrale.In an expedient embodiment of the invention, the individual detectors are switched to what is known as a “closure line”; this is especially so as to avoid false alarms. This means that the individual detectors are only queried at the moment of arming to ensure that all safety devices are effective. If a window or a door is now opened in the armed state, the intrusion detector in question emits one or more pulses wirelessly to the communication unit via its transmitting device. From there, this alarm message is wired to the control center.

- Fig. 2 eine schematische Darstellung der Kommunikationseinheit,

Am Beispiel der Infrarot (IR)-Lichtübertragung ist die Erfindung veranschaulicht. In Fig. 1 sind an den beiden dargestellten Fensterfronten (Mauer M, Fenster F, Stützpfeiler SP, Fenster usw.) jeweils Einbruchdetektoren D angeordnet, die drahtlos mit der in der Mitte des Raumes, im allgemeinen an der Decke, angeordneten Kommunikationseinheit KE in Verbindung stehen. Diese Kommunikationseinheit KE ist drahtgebunden (ML) mit der Zentrale Z verbunden. Wie später noch dargestellt, sammeln die Einbruchdetektoren D über ihre Solarelemente SE aus dem Umgebungslicht die Energie, die sie beispielsweise in einer Pufferbatterie PB speichern, die den Einbruchmelder D mit der benötigten Energie für die Auswerteelektronik und für die Abgabe von Sendesignalen versorgt. Die Kommunikationseinheit KE hat rundum, also radial, eine Reihe von Infrarot-Sende- und Empfangsdioden SE, ED angeordnet, die jeweils sich überlappende Strahlungskeulen aufweisen und somit den Raum rundum bestrahlen. Eine gesonderte Ausrichtung der Einbruchdetektoren D auf die Kommunikationseinheit KE ist dabei nicht erforderlich (Fig.2).The invention is illustrated using the example of infrared (IR) light transmission. In Fig. 1 burglar detectors D are arranged on the two window fronts shown (wall M, window F, pillar SP, window, etc.), which are connected wirelessly to the communication unit KE arranged in the middle of the room, generally on the ceiling stand. This communication unit KE is wired (ML) to the center Z. As will be shown later, the intrusion detectors D, via their solar elements SE, collect the energy from the ambient light, which they store, for example, in a buffer battery PB, which supplies the intrusion detector D with the energy required for the evaluation electronics and for the transmission of transmission signals. The communication unit KE has all around, that is to say radial, a series of infrared transmitting and receiving diodes SE, ED, each of which has overlapping radiation lobes and thus irradiates the room all around. A separate alignment of the intrusion detectors D on the communication unit KE is not necessary (Fig.2).
Fig. 3 zeigt die prinzipielle Anordnung eines Einbruchsdetektors D, der beispielsweise einen Magnetkontakt MK hat, der an der Auswerteelektronik AWE angeschlossen ist. Der Einbruchdetektor D weist eine Infrarot-Empfangsdiode ED und mindestens eine Infrarot-Sendediode SD auf. Ferner weist der Einbruchdetektor D Solarelemente SE auf, die aus dem Umgebungslicht die Energie gewinnen und in elektrische Energie umwandeln und die in einem entsprechenden Energiespeicher PB für die Versorgung der Auswerteelektronik und der daran angeschlossenen Infrarot-Sende- und Empfangsdioden gespeichert wird.FIG. 3 shows the basic arrangement of an intrusion detector D, which has, for example, a magnetic contact MK which is connected to the evaluation electronics AWE. The intrusion detector D has an infrared receiving diode ED and at least one infrared transmitting diode SD. Furthermore, the intrusion detector D has solar elements SE, which extract the energy from the ambient light and convert it into electrical energy, and which is stored in a corresponding energy store PB for supplying the evaluation electronics and the infrared transmitter and receiver diodes connected to it.
Fig. 4 zeigt die mögliche Ausbildung eines erfindungsgemäßen Einbruchdetektors D mit einer Reihe von Solarelementen SE, mit hier nur einer Infrarot-Empfangsdiode, die jedoch vorgesetzt eine Sammeloptik SO aufweist, die sehr breit ausgebildet ist, so daß ein sicherer Empfang der Infrarotsignale von der Kommunikationseinheit KE ermöglicht wird. Ferner weist der Einbruchdetektor zwei Sendedioden SD auf.Fig. 4 shows the possible design of a burglar detector D according to the invention with a series of solar elements SE, here with only one infrared receiving diode, which, however, has a collecting optics SO, which is very wide, so that the infrared signals are received reliably from the communication unit KE is enabled. The intrusion detector also has two transmission diodes SD.
In einer Weiterbildung der Erfindung kann die Einbruchmeldeanlage, wenn für die Übertragungsstrecke IR-Licht benutzt wird, auch zur Brandüberwachung herangezogen werden. Wird die Übertragungsstrecke regelmäßig auf Funktionsfähigkeit überwacht, indem IR-Lichtimpulse von den einzelnen Meldern zur Kommunikationseinheit erzeugt und überprüft werden, so kann die Kommunikationseinheit auch überprüfen, ob eine bestimmte Lichtschwächung eingetreten ist. Dabei ist bei einer vorgebbaren Dämpfung aufgrund von Rauch ein Brandalarm ableitbar.In a development of the invention, the intruder alarm system can also be used for fire monitoring if IR light is used for the transmission link. If the transmission path is regularly monitored for functionality by generating and checking IR light pulses from the individual detectors to the communication unit, the communication unit can also check whether a certain light attenuation has occurred. A fire alarm can be derived if the damping can be specified.
