Abstract
Description
Die Erfindung betrifft eine Überwachungseinrichtung mit batteriebetriebenen Überwachungsgeräten, die jeweils eine Alarmeinrichtung aufweisen, und insbesondere eine Überwachungseinrichtung mit mehreren ein Funknetz bildenden Rauchmeldern.The invention relates to a monitoring device with battery operated Monitoring devices, each with an alarm device have, and in particular a monitoring device with several smoke detectors forming a radio network.
Eine Überwachungseinrichtung dient dazu, gewisse Gefahrensituationen an verschiedenen Orten zu erkennen und zu melden. Beispielsweise sind Rauchmelder oder Einbruchmelder bekannt, die jeweils einen Raum oder ein Gebiet erfassen und Alarmsignale liefern, wenn das zu überwachende Ereignis in diesem Bereich eintritt. Um den Installationsaufwand bei Überwachungseinrichtungen zu reduzieren, wurden batteriebetriebene Überwachungsgeräte entwickelt, die ohne weitere Verkabelung vom Anwender installiert werden können. Jedes Überwachungsgerät ist mit einer eigenen Alarmeinrichtung versehen. Im Falle des Ansprechens wird beispielsweise ein akustischer Alarm erzeugt. A monitoring device is used to detect certain dangerous situations to recognize and report in different places. For example, smoke detectors or intrusion detectors are known which each capture a room or an area and alarm signals deliver if the event to be monitored in this area entry. The installation effort for monitoring devices to reduce battery-powered monitoring devices developed by the user without further wiring can be installed. Every monitoring device is provided with its own alarm device. In the event of a response for example, an acoustic alarm is generated.
Wenn nun an unterschiedlichen Stellen eines Gebäudes Überwachungsgeräte installiert sind, kann es vorkommen, dass ein akustisches Signal, das von einer Überwachungseinrichtung erzeugt wird, von Personen, die sich in anderen Räumen befinden, nicht wahrgenommen wird. Ertönt beispielsweise die Alarmeinrichtung eines im Keller installierten Überwachungsgerätes, so ist davon auszugehen, dass dieser Alarm in einem Zimmer, das sich im ersten Stock befindet, nicht gehört wird.If there are monitoring devices at different locations in a building installed, it can happen that a acoustic signal generated by a monitoring device by people who are in other rooms, is not perceived. For example, the alarm device sounds a monitoring device installed in the basement, so it can be assumed that this alarm in a room that is on the first floor, is not heard.
Wenn mehrere Überwachungsgeräte durch ein Kabelnetz miteinander verbunden sind, kann man die Überwachungsgeräte in der Weise betreiben, dass im Alarmfall alle Geräte gemeinsam aktiviert werden und sämtlich Alarm erzeugen. Bei Verzicht auf ein Kabelnetz müssen die Überwachungsgeräte mit Sendern und Empfängern ausgestattet sein. Bei Batteriebetrieb hat dies jedoch zur Folge, dass die Empfänger ständig empfangsbereit sein müssen. Ein Empfänger benötigt bei einer Betriebsspannung von 5 V einen Versorgungsstrom von ca. 10 mA, um in dem in Betracht kommenden Frequenzband ausreichend empfindlich und stabil arbeiten zu können. Bei einer Batteriekapazität von 500 mAh könnte man den Empfänger fünfzig Stunden lang in Betrieb halten. Dies bedeutet, dass die Batterie etwa alle 2 Tage gewechselt werden müsste, was nicht akzeptabel wäre.When multiple monitors are connected by a cable network connected, one can monitor the devices in the way operate that all devices are activated together in the event of an alarm and all generate an alarm. If you do not have a cable network the monitoring devices must have transmitters and receivers be equipped. In battery operation, however, this has the As a result, the recipients must be constantly ready to receive. A receiver requires one at an operating voltage of 5 V. Supply current of about 10 mA to be considered in the The frequency band is sufficiently sensitive and stable to work can. With a battery capacity of 500 mAh you could Keep the receiver in operation for fifty hours. This means, that the battery be changed about every 2 days would have to, which would not be acceptable.
Eine Überwachungseinrichtung, von der der Oberbegriff des Patentanspruchs 1 ausgeht, ist beschrieben in US-A-6,078,269. Diese Überwachungseinrichtung weist mehrere batteriebetriebene Überwachungsgeräte auf, die über Sender und Empfänger miteinander kommunizieren. Der Empfänger eines Überwachungsgerätes wird jeweils in Zeitintervallen nur für eine kurze Zeit aktiviert. Nach Ansprechen eines Überwachungsgerätes sendet der Sender dieses Überwachungsgerätes ein Sendersignal aus, das länger dauert als das Zeitintervall der Empfängeraktivierung.A monitoring device, of which the preamble of Claim 1 starts, is described in US-A-6,078,269. This monitoring device has several battery operated Monitoring devices based on transmitters and receivers communicate with each other. The recipient of a Monitoring device is only in time intervals for activated for a short time. After addressing one The transmitter sends this monitoring device Monitoring device a transmitter signal that lasts longer than the time interval of the receiver activation.
Der Erfindung liegt die Aufgabe zugrunde, eine Überwachungseinrichtung mit batteriebetriebenen Überwachungsgeräten zu schaffen, die eine lange Gebrauchsdauer der Batterie ermöglicht, d.h. lange Batteriewechselzyklen zulässt.The invention has for its object a monitoring device to create with battery powered monitoring devices which enables a long service life of the battery, i.e. allows long battery replacement cycles.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Patentanspruch 1 angegebenen Merkmalen. Hiernach wird der Empfänger eines Überwachungsgerätes in Zeitintervallen jeweils für eine kurze Zeit aktiviert und anschließend wieder abgeschaltet. This object is achieved with the im Features specified claim 1. After that, the recipient of a monitoring device in time intervals for each activated for a short time and then switched off again.
In einem Überwachungsgerät haben Sender und Empfänger jeweils im aktivierten Zustand einen hohen Stromverbrauch. Der Sender braucht nur dann aktiviert zu werden, wenn der zugehörige Melder ein zu meldendes Ereignis festgestellt hat. Dies bedeutet, dass der Sender abgeschaltet oder in einer Schlummerfunktion gehalten werden kann. Dagegen müsste der Empfänger eigentlich permanent aktiviert sein, um auf ein Sendesignal eines anderen Überwachungsgerätes reagieren zu können. Der Empfänger wird jedoch nur in Zeitintervallen jeweils für eine kurze Zeit aktiviert. Im Falle eines Ansprechens eines Überwachungsgerätes sendet der Sender für eine Zeitspanne, die größer ist als ein Zeitintervall der Empfängeraktivierung, ein Sendersignal aus. Der Empfänger wird in vorbestimmten Intervallen kurzfristig eingeschaltet, um zu horchen, ob Sendersignale vorliegen. Die Dauer des Zeitintervalls der Empfängeraktivierung beträgt in der Praxis etwa 40 bis 50 Sekunden. Dadurch ergibt sich eine Verzögerung zwischen der Auslösung eines Überwachungsgerätes und der Alarmerzeugung eines anderen Überwachungsgerätes. Die Erfindung geht von dem Gedanken aus, dass es im allgemeinen tolerierbar ist, wenn bei einer Vernetzung von Überwachungsgeräten zwischen dem auslösenden Alarm und dem letzten ausgelösten Alarm eine Zeitver-. zögerung liegt, wenn diese Zeitverzögerung ein bestimmtes vorgegebenes Maß nicht übersteigt. Die maximal mögliche Zeitverzögerung kann beispielsweise im Fall eines Rauchmeldesystems etwa 50 Sekunden betragen. Durch diesen Kompromiss gelingt es, die Batterielebensdauer auf etwa 2 Jahre auszudehnen.In a monitoring device, the transmitter and receiver each have high power consumption when activated. The transmitter only needs to be activated if the associated detector has detected an event to be reported. This means, that the transmitter is switched off or in a snooze function can be held. On the other hand, the recipient should actually be permanently activated to respond to a broadcast signal from another Monitor can respond. However, the receiver is only used for one at time intervals activated for a short time. In the event of a monitoring device responding the transmitter sends for a period of time that is greater than a time interval for receiver activation, a Transmitter signal off. The receiver turns on at predetermined intervals turned on briefly to listen for transmitter signals available. The duration of the time interval of the In practice, receiver activation takes around 40 to 50 seconds. This results in a delay between tripping of a monitoring device and the generation of an alarm other monitoring device. The invention is based on the idea from that it is generally tolerable if at a network of monitoring devices between the triggering Alarm and the last alarm triggered a time delay. There is a delay if this time delay is a certain predetermined one Dimension does not exceed. The maximum possible time delay can, for example, in the case of a smoke alarm system about 50 seconds. With this compromise, extend the battery life to about 2 years.
Die erfindungsgemäße Überwachungseinrichtung weist Überwachungsgeräte auf, die völlig autark sind und weder einen Netzanschluss noch ein Übertragungsnetz benötigen. Daher ist die Installation besonders einfach. Die Überwachungsgeräte brauchen nur aufgestellt und eingeschaltet zu werden. Die Überwachungseinrichtung kann eine Brandmeldeeinrichtung, eine Zugangsüberwachungseinrichtung oder auch eine Bewegungsmeldeeinrichtung sein.The monitoring device according to the invention has monitoring devices who are completely self-sufficient and neither Network connection still need a transmission network. thats why installation is particularly easy. The monitoring devices only need to be set up and switched on. The monitoring device can be a fire alarm device, an access monitoring device or a motion detection device his.
Bei der Erfindung ist vorgesehen, dass nach Ablauf der Zeitspanne der Sender in Zeitintervallen jeweils ein kurzes Sendersignal aussendet und dass der Empfänger jeweils für eine Nachlaufzeit neu aktiviert wird, wenn während einer Empfängeraktivierung ein Sendersignal empfangen wird, wobei die Nachlaufzeit größer ist als das Zeitintervall der Sendersignale. Auf diese Weise wird auch die Batterie desjenigen Überwachungsgerätes geschont, dessen Melder angesprochen hat und dessen Sender aktiviert wurde. Der Sender erzeugt zunächst über die vorgegebene Zeitspanne hinweg das Sendersignal, das von sämtlichen Überwachungsgeräten zu verschiedenen Zeiten erkannt wird. Nach Ablauf der Zeitspanne wird zur Schonung der Batterie des sendenden Überwachungsgerätes das Sendersignal auf kurze Signale reduziert. Diese triggern jeweils die Empfänger der anderen Überwachungsgeräte in der Weise, dass die Empfänger permanent.aktiviert bleiben, solange der Meldezustand anhält. Auf diese Weise wird verhindert, dass die Batterie des sendenden Überwachungsgerätes durch einen permanenten Sendezustand zu sehr belastet wird.The invention provides that after the lapse of time the transmitter in time intervals sends out a short transmitter signal and that the Receiver is reactivated for a follow-up time, if there is a transmitter signal during receiver activation is received, the follow-up time being greater than the time interval of the transmitter signals. This way the battery will also spared of the monitoring device, the detector has responded and its transmitter has been activated. The transmitter first creates the over the specified period of time Transmitter signal from all monitoring devices to different Times is recognized. After the time period is over to protect the battery of the sending monitoring device Transmitter signal reduced to short signals. These each trigger the receivers of the other monitoring devices in the Way that the receivers remain permanently activated as long as the message status continues. This prevents the battery of the sending monitoring device by a permanent one Send state is too stressed.
Grundsätzlich besteht die Möglichkeit, das bloße Vorhandensein von Sendersignalen zu erfassen. Vorzugsweise enthalten jedoch die Sendersignale digitale Telegramme, welche bestimmte andere Überwachungsgeräte adressieren. Auf diese Weise kann festgelegt werden, welche Überwachungsgeräte miteinander kommunizieren.Basically, there is the possibility of mere existence of transmitter signals. Preferably included however the transmitter signals digital telegrams, which certain other Address monitoring devices. This way you can set which monitoring devices communicate with each other.
Es kann ferner zweckmäßig sein, dass das Sendersignal eine Alarminformation enthält, die einen Alarmzustand von dem Zustand unterscheidet, in welchem nur ein Testknopf betätigt wurde. Bei Betätigung eines Testknopfes kann die Alarmgabe während der Dauer der relativ langen Nachlaufzeit verhindert werden.It may also be appropriate for the transmitter signal to be a Contains alarm information that indicates an alarm condition from the condition distinguishes in which only one test button is pressed has been. If a test button is pressed, the alarm can be given during the duration of the relatively long run-on time can be prevented.

22, das zum Zeitpunkt t0 beginnt und sich über eine festgelegte
Zeitspanne TS erstreckt. Diese Zeitspanne beträgt hier 60
Sekunden. Vor dem Zeitpunkt t0 war der Sender abgeschaltet,
d.h. in einem Schlummerzustand.If the
In Figur 2 ist in der dritten Zeile das Aktivierungssignal
eines Empfängers E eines anderen Überwachungsgerätes dargestellt,
welches die Signale des ersten Überwachungsgerätes
empfängt. Bevor der Sender S des ersten Überwachungsgerätes ein
Sendersignal liefert, wird der Empfänger E des "horchenden"
Überwachungsgerätes jeweils für eine kurze Zeit aktiviert. Das
Signal zur Aktivierung des Empfängers kann entweder vom Steuergerät
14 oder in dem Fall des Rauchmelders vom Melder 12 erzeugt
werden. Die Aktivierungszeiten sind mit AT bezeichnet.
Zwischen zwei Aktivierungszeiten AT erstrecken sich Zeitintervalle
TIE der Empfängeraktivierung. Ein Zeitintervall TIE hat
eine Dauer von 40 bis 50 sec. Die Aktivierungszeit AT hat eine
Dauer von ca. 1 sec. Da das Zeitintervall TIE kürzer ist als
die Zeitspanne TS des Sendersignals, fällt mit Sicherheit eine
Aktivierungszeit AT in die Zeitspanne TS. In dieser Aktivierungszeit
AT erkennt der Empfänger E, dass der Sender S ein
Sendersignal 21 aussendet. Daraufhin wird der Empfänger E aktiviert,
was in Figur 2 mit 23 bezeichnet ist. Der Empfänger
bleibt so lange aktiviert, wie das Sendersignal 21 empfangen
wird, und darüber hinaus noch für eine Nachlaufzeit TN.In FIG. 2, the activation line of a receiver E of another monitoring device is shown in the third line, which receives the signals of the first monitoring device. Before the transmitter S of the first monitoring device delivers a transmitter signal, the receiver E of the "listening" monitoring device is activated for a short time. The signal for activating the receiver can be generated either by the
