Description

Elektronisches Sicherheitssystem, vorzugsweise zum Schutz von Wohnungen, die mit Kabelfernsehanschluß ausgestattet sind Electronic security system, preferably to protect homes that are equipped with cable television connections
Technisches GebietTechnical field
Die Erfindung betrifft ein elektronisches Sicherheitssys¬ tem, vorzugsweise zum Schutz von Wohnungen, deren geschütz¬ ter Raum mit einer Zentrale ausgestattet ist, an die eine Einrichtung zur Betätigung der Zentrale und zumindest ein Fühler angeschaltet sind,und die über eine Kabelleitung des Kabelfernsehens an ein Zentralsteuerpult angeschlossen ist.The invention relates to an electronic security system, preferably for the protection of dwellings, the protected space of which is equipped with a control center, to which a device for actuating the control center and at least one sensor is connected, and which via a cable line of cable television to one Central control panel is connected.
Bisheriger Stand der TechnikCurrent state of the art
Es sind Sicherheitssysteme bekannt, die zum Schutz von Gruppen von Räumen, z.B. Wohnungen, gegen Einbruch, Brand, Gasausströmen udg. dienen. Bekannte Sicherheitssysteme die¬ ser Art bestehen aus Elementen, die sich im geschützten Raum befinden, aus Verbindungselementen und einem Zentral¬ steuerpult. Im Inneren des geschützten Raumes befindet sich eine mit dem Zentralsteuerpult verschaltete elektronische Zentrale, d.h. eine Auswertungseinrichtung, an die ver¬ schiedene Fühler und ein Betätigungselement angeschlossen sind, wobei das Betätigungselement dazu bestimmt ist, die Berechtigung der einzutretenden Person zum Eintritt in den geschützten Raum auszuwerten und gegebenenfalls Einstellung neuer Zutrittsbedingungen zu ermöglichen. Die Zentrale kann mit einer Reservestromquelle und/oder mit einer Sirene aus¬ gestattet werden. Die Fühler sind im wesentlichen Schleifen mit binärem Aus¬ gang - eingeschaltet/ausgeschaltet. Sie sind entweder aktiv und benötigen Stromversorgung, z.B. Infrarotfühler, Fühler für Detektion von elektromagnetischer oder akustischer Wel¬ lenbewegung, oder passiv - ohne Stromversorgung, z.B. mag¬ netische Kontakte und Mikroschalter. Die binäre Information wird vom Fühler in die Zentrale durch ein Kabel oder durch Funkübertragung geleitet. Die Zentrale hat zur Aufg be,den Stand der Fühler und die von der Betätigungseinrichtung kommende Information auszuwerten und anschließend ein Alarmsignal oder eine andere Information an das Zentral¬ steuerpult zu schicken oder die Sirene einzuschalten.Security systems are known which are used to protect groups of rooms, for example apartments, against burglary, fire, gas escapes. serve. Known security systems of this type consist of elements which are located in the protected space, of connecting elements and a central control panel. In the interior of the protected room there is an electronic center connected to the central control desk, ie an evaluation device to which various sensors and an actuating element are connected, the actuating element being designed to evaluate the authorization of the person to enter the protected space and, if necessary, to enable setting of new access conditions. The control center can be equipped with a reserve power source and / or with a siren. The sensors are essentially loops with a binary output - switched on / off. They are either active and require a power supply, for example infrared sensors, sensors for detecting electromagnetic or acoustic shaft movement, or passively - without a power supply, for example magnetic contacts and microswitches. The binary information is sent from the sensor to the control center via a cable or by radio transmission. The central unit has the task of evaluating the position of the sensors and the information coming from the actuating device and then sending an alarm signal or other information to the central control panel or switching on the siren.
Das Betätigungselement der Zentrale empfängt eine Identifi¬ kationsinformation von der einzutretenden Person. Diese Information befindet sich in einem mechanischen, magneti¬ schen oder elektronischen Schlüssel oder wird durch eine von dieser Person betätigten Tastatur dem System zugeleitet. Außerdem können, meistens durch die Tastatur, neue Bedin¬ gungen für den Zutritt in den geschützten Raum eingestellt werden.The actuating element of the control center receives identification information from the person to be entered. This information is located in a mechanical, magnetic or electronic key or is fed to the system by a keyboard operated by this person. In addition, new conditions for access to the protected room can be set, usually using the keyboard.
Beim Eintritt in den geschützten Raum wird ein Zeitgeber in der Zentrale z.B.durch einen magnetischen Fühler eingeschal¬ tet, und die eingetretene Person hat in einer eingestell¬ ten Zeit das System auszuschalten, sei es durch ihr Schlüs¬ sel oder durch die Tastatur. Sonst wird Angriff des ge¬ schützten Raumes signalisiert. Die Person wird meistens durch ein akustisches oder ein Lichtsignal darauf aufmerk¬ sam gemacht, daß die Zeit zu Ende geht.When entering the protected room, a timer in the control center is switched on, for example by a magnetic sensor, and the person entering has to switch off the system in a set time, be it with their key or the keyboard. Otherwise, attack of the protected area is signaled. The person is usually made aware by an acoustic or light signal that the time is running out.
Bei bekannten Sicherheitssystemen wird die Information von der Wohnungszentrale dem Zentralsteuerpult über eigene ge¬ trennte Telefonleitung in einer binären Form zugeleitet o- der über gewöhnliche Telefonleitungen, u.z.gleichfalls als binäre Information im Frequenzband über der Frequenz der Telefongespräche,oder in einer digitalen Form im Frequenz¬ band der Gespräche, als komplette alphanumerische Informa¬ tion.In known security systems, the information from the central apartment unit is fed to the central control console via its own separate telephone line in a binary form or via ordinary telephone lines, likewise as Binary information in the frequency band over the frequency of the telephone calls, or in a digital form in the frequency band of the calls, as complete alphanumeric information.
Nachteilig an Systemen mit getrennten Telefonleitungen und an solchen, die das Frequenzband der Telefongespräche benutzen, ist, daß sie verhältnismäßig leicht angreifbar sind. Zu den größten Nachteilen des Sicherheitssystems mit Informationsübertragung im Frequenzband über der Gesprächs¬ frequenz gehört, daß das Signal lediglich durch eine einzi¬ ge Telefonzentrale geht. Sollte darüber hinaus innerhalb der Leitung noch eine Hauszentrale oder eine weitere kommu¬ nale Zentrale eingeschaltet werden, könnte die Verbindung überhaupt nicht realisiert werden. Die Errichtung von ge¬ trennten Telefonleitungen ist sehr kostspieleg; Massenein¬ satz von gewohmlichen Telefonleitungen kommt nicht in Frage in Kommunen, die nicht genügend telefonisiert sind.A disadvantage of systems with separate telephone lines and those that use the frequency band of the telephone calls is that they are relatively easy to attack. One of the biggest disadvantages of the security system with information transmission in the frequency band above the conversation frequency is that the signal only goes through a single telephone exchange. If, in addition, a house control center or another communal control center was switched on within the line, the connection could not be established at all. The establishment of separate telephone lines is very expensive; Mass use of ordinary telephone lines is out of the question in municipalities that are not sufficiently telephoned.
Es sind Sicherheitssysteme bekannt, bei denen die Informa¬ tion von der Wohnungszentrale dem Zentralsteuerpult über Leitungen des Kabelfernsehens zugeleitet wird. In diesen bekannten Systemen werden die Standardzentralen in einzel¬ nen geschützten Wohnungen von dem Zentralsteuerpult perio¬ disch befragt, und diese übermitteln dem Steuerpult mit einer Periodizität von ca 6s. Information über deren Stand.Security systems are known in which the information is fed from the central apartment unit to the central control panel via cable television lines. In these known systems, the standard centers in individually protected dwellings are periodically polled by the central control panel, and these transmit them to the control panel with a periodicity of approximately 6s. Information about their status.
Nachteilig an den bekannten Sicherheitssystemen, die zur Übertragung von Informationen Kabelfernsehleitungen benut¬ zen, ist ihre leichte Angreifbarkeit, weil das geschützte Objekt zwischen den Abfragen von dem Zentralsteuerpult nicht überwacht werden kann, was Gelegenheit für die Zu¬ schaltung eines Emulators bietet.A disadvantage of the known security systems, which use cable television lines for the transmission of information, is that they can be easily attacked because the protected object cannot be monitored between queries by the central control panel, which offers the opportunity for the connection of an emulator.
Sollte es im allgemeinen zu einem Masseneinsatz eines Si- cherheitssystems in Wohnhäusern,Häuserblocks oder Wohnvier¬ teln kommen, sollte das System den folgenden Anforderungen entsprechen:In general, should a Si security system in residential buildings, blocks of houses or residential quarters, the system should meet the following requirements:
- Das technische Niveau entspricht den gültigen Standarden.- The technical level corresponds to the valid standards.
- Die Betätigung ist den Personen im Alter ab 8 Jahren möglich.- The activity is possible for people aged 8 and over.
- Das System ist gegen Mißbrauch von Zutrittsberechtigungen gesichert.- The system is secured against misuse of access authorizations.
- Anschaffungskosten zumindest der Grundvariante sind für alle im Einsatzgebiet lebenden sozialen Schichten akzep¬ tabel.- Acquisition costs of at least the basic variant are acceptable for all social classes living in the area of application.
- Das System ist genügend variabel, um einen gewünschten Komfort entsprechend dem Sozialstatus der Benutzer zu bieten.- The system is sufficiently variable to offer a desired comfort according to the social status of the users.
Die bekannten Systeme haben zum Nachteil, daß sie mindes¬ tens eine der obigen Anforderungen nicht erfüllen: Die Be¬ dingung der Zugänglichkeit ist bei den mit einem mechani¬ schen oder elektronischen Schlüssel betätigten Systemen er¬ füllt, jedoch sind Systeme mit einem mechanischen Schlüssel im Fall des Schlüsselverlustes gefährdet, und Systeme mit einem elektronischen Schüssel sind wegen ihrer hohen An¬ schaffungskosten für breite Schichten unerschwinglich.The known systems have the disadvantage that they do not meet at least one of the above requirements: the condition of accessibility is fulfilled in the systems operated with a mechanical or electronic key, but systems with a mechanical key are If the key is lost, systems with an electronic key are unaffordable for broad layers because of their high purchase costs.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Sicher¬ heitssystem zu schaffen, das alle Bedingungen für den Mas¬ seneinsatz in Wohnvierteln erfüllt.The invention is therefore based on the object of providing a security system which meets all the conditions for mass use in residential areas.
Darstellung der ErfindungPresentation of the invention
Zur Lösung der Aufgabe ist ein elektronisches Sicherheits¬ system vorgesehen, vorzugsweise zum Schutz von Wohnungen, deren geschützter Raum mit einer Zentrale ausgestattet ist, an die eine Einrichtung zur Betätigung der Zentrale und zu¬ mindest ein Fühler angeschaltet sind, und die über eine Ka- belleitung des Kabelfernsehens an ein Zentralsteuerpult an¬ geschlossen ist, wobei die Zentrale ein,außer Null-Zustand, zumindest eine Hochfrequenz generierender Kodeerkennungs¬ prozessor, und die Einrichtung zur Betätigung der Zentrale eine Einrichtung zum Lesen von Chip-Karten ist.To solve the problem, an electronic security system is provided, preferably for the protection of apartments, the protected space of which is equipped with a control center, to which a device for actuating the control center and at least one sensor are connected, and which are connected via a cable of the cable television is connected to a central control console, the control center being, apart from the zero state, at least one radio-frequency-generating code recognition processor, and the device for actuating the control center being a device for reading chip cards.
In einer vorteilhaften Ausgestaltung der Erfindung gene¬ riert der Kodeerkennungsprozessor,außer Null-Zustand, Hoch¬ frequenz von zwei verschiedenen Schwingungszahlen.In an advantageous embodiment of the invention, the code recognition processor generates, apart from the zero state, high frequency of two different oscillation numbers.
In einer für den Masseneinsatz besonders vorteilhaften Aus¬ führung ist ein Gruppendekodierer zum Dekodieren des von den Kodeerkennungsprozessoren generierten Frequenz-Spekt¬ rums zwischen eine Gruppe von Identifikationsprozessoren und das Zentralsteuerpult eingeschaltet.In a particularly advantageous embodiment for mass use, a group decoder for decoding the frequency spectrum generated by the code recognition processors is switched between a group of identification processors and the central control panel.
In einer alternativen Ausgestaltung des Sicherheitssystems ist eine Stromversorgungsquelle und/oder eine Ersatzstrom¬ versorgungsquelle an den Kodeerkennungsprozessor angeschal¬ tet. Dann können zumindest ein aktiver Fühler und/oder eine Code-Tastatur an den Kodeerkennungsprozessor angeschaltet werden.In an alternative embodiment of the security system, a power supply source and / or a backup power supply source is connected to the code recognition processor. Then at least one active sensor and / or a code keyboard can be connected to the code recognition processor.
Die Kodeerkennungsprozessoren und das Zentralsteuerpult sind vorteilhaft mit Modems zur beidseitigen Kommunikation ausgestattet. An den Kodeerkennungsprozessor können Aus¬ gänge von Wohnungsmeß- und Regelungsgeräten angeschaltet werden.The code recognition processors and the central control panel are advantageously equipped with modems for two-way communication. Outputs of apartment measuring and control devices can be connected to the code recognition processor.
In dieser Ausführung erfüllt das System außer der Sicher¬ heitsfunktion auch eine Reihe von zusätzlichen Informati- ons- und Regelungsfunktionen.

Ausführungsbeispiele der ErfindungEmbodiments of the invention
Die elementare Ausführung des Sicherheitssystems besteht aus Kodeerkennungsprozessoren 1 , die an die zu Fernsehgerä¬ ten führenden Wohnungsanschlüsse 2 angeschlossen sind. An die Kodeerkennungsprozessoren 1. sind Einrichtungen 4_ zum Lesen von Karten mit integrierten Chips angeschaltet, oder gegebenenfalls sind diese ein direkter Bestandteil der Kodeekennungsprozessoren 1. An den Kodeerkennungsprozessor 1. ist weiterhin ein passiver Fühler j5 angeschlossen, der im Bereich der Eingagngstür der Wohnung angebracht ist. Wohnungsfernsehanschlüsse 2 sind mittels eines Standard¬ fernsehtranslators 6 und Zweige 1_ des Verteilungskabel¬ netzes an das Sendezentrum 8. des Kabelfernsehens ange¬ schlossen. In dem Punkt, wo die Zweige 1_ zusammenkommen,ist ein Zentralsteuerpult 9_ daran angeschlossem - ein Computer- Subsystem zur Überwachung der geschützten Räume und zur Verarbeitung der von dort kommenden Alarm- und technischen Informationen. Ein ständiger Dienst am Zentralsteuerpult 9> wird vorausgesetzt. Der Kodeerkennungsprozessor 1 befindet sich hinter der Eingangstür im Inneren des geschützten Raumes. Als ein pas¬ siver Fühler 5 kann z.B.ein in der Eingangstür angebrachter magnetischer Schalter benutzt werden. Der Kodeerkennungs¬ prozessor 1. gibt ein Signal von Fequenz A in das Kabelfern¬ sehnetz. Beim Eintritt einer Person in die Eingangstür wird vom Fühler 5 ein Zeitgeber im Kodeerkennungsprozessor 1 an¬ gelassen. Während der eingestellten Zeit muß die eingetre¬ tene Person ihre Karte mit integriertem Chip in die Lese¬ einrichtung 4. hineinlegen. Solange dies geschieht und die Karte als berechtigend anerkannt ist, ändert der Kodeerken¬ nungsprozessor die Schwingungszahl von A zu B. Im Falle, daß die Karte nicht hineingelegt wird oder als nicht be¬ rechtigend identifiziert ist, hört der Kodeerkennungspro¬ zessor (1) auf, zu emittieren. Die Frequenz Null bedeutet einen AIarm-Zustand. Jeder der Kodeerkennungsprozessoren 1. hat seine eigene Frequenz A, die einer leeren Wohnung ent¬ spricht, und seine charakteristische Frequenz B, die einer berechtigt besetzten Wohnung entspricht. Die Frequenzen A bzw. B, die von einzelnen Kodeerkennungsprozessoren 1 des Systems emittiert werden,bilden im Kabelnetz des Kabelfern¬ sehens ein Spektrum, das vom Zentralsteuerpult entschlüs¬ selt wird. Das Zentralsteuerpult 9_ registriert die Anwesen¬ heit von einzelnen Komponenten des Spektrums und wertet den Stand einzelner geschützten Wohnungen aus, d.h. deren Fre¬ quenz A = leere Wohnung, Frequenz B = berechtigt besetzte Wohnung und Frequenz 0 = angegriffene Wohnung. Im letzteren Fall wird Alarm geschlagen und ein Angriffskommando akti¬ viert.The basic version of the security system consists of code recognition processors 1, which are connected to the apartment connections 2 leading to televisions. Devices 4_ for reading cards with integrated chips are connected to the code recognition processors 1. or, if appropriate, these are a direct component of the code recognition processors 1. A passive sensor j5 is also connected to the code recognition processor 1. and is attached in the area of the entrance door of the apartment . Apartment television connections 2 are connected to the transmission center 8 by means of a standard television translator 6 and branches 1_ of the distribution cable network . connected to the cable television. At the point where branches 1_ come together, a central control panel 9_ is connected to it - a computer subsystem for monitoring the protected rooms and for processing the alarm and technical information coming from there. Permanent service at the central control panel 9> is required. The code recognition processor 1 is located behind the entrance door inside the protected room. For example, a magnetic switch mounted in the entrance door can be used as a passive sensor 5. The code recognition processor 1. outputs a signal of frequency A in the cable television network. When a person enters the front door, the sensor 5 starts a timer in the code recognition processor 1. During the set time, the person entering must insert their card with an integrated chip into the reading device 4. As long as this happens and the card is recognized as being legitimate, the code recognition processor changes the number of oscillations from A to B. In the event that the card is not inserted or is identified as not being legitimate, the code recognition processor (1) stops to emit. The zero frequency means an alarm condition. Each of the code recognition processors 1. has its own frequency A, which corresponds to an empty apartment, and its characteristic frequency B, which corresponds to an authorized apartment. The frequencies A and B, which are emitted by individual code recognition processors 1 of the system, form a spectrum in the cable network of cable television, which is decrypted by the central control panel. The central control panel 9_ registers the presence of individual components of the spectrum and evaluates the status of individual protected apartments, ie their frequency A = empty apartment, frequency B = authorized apartment and frequency 0 = attacked apartment. In the latter case, an alarm is raised and an attack command is activated.
In der beschriebenen Elementarausführung ist die maximale Zahl der ins System einzubeziehenden Wohnungen durch die Ü- bertragungskapazität des Systems auf 1024 begrenzt. Um die¬ se Begrenzung zu erhöhen,wurde ein erweitertes Sicherheits¬ system nach Fig. 2 entworfen, das im Bereich von Fernseh- translatoren §_ Gruppendekodierer ,10. aufweist. Die Gruppen¬ dekodierer iO. emittieren eigene Frequenzen. Ihre Aufgabe ist es, das von zugehörigen Kodeerkennungsprozessoren 1 ge¬ sendete Frequenz-Spektrum zu analysieren, wobei die Ände¬ rung der Frequenzebene A, B und 0 eines jeden Prozessors 1. die eigne Frequenz des Gruppendekodierers ändert, was im Zentralsteuerpult £ registriert wird. Gleichzeitig schaltet der Gruppendekodierer den betroffenen Kodeerkennungsprozes¬ sor 1. mit dem Zentralsteuerpult 9_ durch,und sichert so eine Registrierung von Änderungen in der Wohnung.In the elementary version described, the maximum number of apartments to be included in the system is limited to 1024 by the transmission capacity of the system. In order to increase this limitation, an extended security system according to FIG. 2 was designed, which is used in the area of television translators §_ group decoder , 10. has. The group decoder OK. emit their own frequencies. Its task is to analyze the frequency spectrum transmitted by the associated code recognition processors 1, the change in the frequency levels A, B and 0 of each processor 1 changing the own frequency of the group decoder, which is registered in the central control panel £. At the same time, the group decoder switches through the code recognition processor 1 concerned with the central control panel 9_, and thus ensures that changes are registered in the home.
In der obigen Beschreibung der Elementarausführung und der erweiterten Ausführung des Sicherheitssystems wurde ledig¬ lich die Grundausstattung der Wohnung erwähnt, die aus ei¬ nem Kodeerkennungsprozessor 1 mit einer Einrichtung 4_ zum Lesen von Karten mit integriertem Chip und einem passiven Fühler 5, in der Eingangstür besteht. Diese Ausstattung kann nur die elementare Sicherheitsfunktion erfüllen. Das System ermöglicht jedoch, nach Wunsch der Wohnungsinhaber Zusatzeinrichtungen in einzelnen Wohnungen zu installieren, die an das vorgeschlagene System mittels einer Standard¬ zentrale angeschlossen werden können. Dadurch erhöht sich der Komfort der Benutzer. Die Kodeerkennungsprozessoren können an eine Stromquelle 1_1 angeschlossen werden, wodurch Installierung von mit dem Prozessor 1 durchgeschalteten ak¬ tiven Fühler 12. ermöglicht ist. Für den Fall eines Strom¬ ausfalls wird eine Ersatzstromquelle 1 installiert. Nach¬ dem diese erschöpft ist, schaltet der Kodeerkennungsprozes¬ sor 1. auf Stand 0 um, und das Zentralsteuerpult 9_ nimmt ei¬ nen Angriffszustand wahr. Die Stromquelle .11, ermöglicht weiterhin, eine Kode-Tastatur 14. zum Prozessor 1 zuzuschal¬ ten. Mittels dieser Tastatur 14. können z.B. Zutrittsbedin¬ gungen direkt vom Wohnungsbesitzer geändert werden.In the above description of the basic version and the extended version of the security system, only the basic equipment of the apartment was mentioned, which consists of a code recognition processor 1 with a device 4_ for reading cards with an integrated chip and a passive sensor 5 in the entrance door . This equipment can only fulfill the basic safety function. However, the system allows additional equipment to be installed in individual apartments at the owner's request, which can be connected to the proposed system by means of a standard control center. This increases user comfort. The code recognition processors can be connected to a current source 1_1, which enables the installation of active sensors 12 connected through the processor 1. In the event of a power failure, a backup power source 1 is installed. After this has been exhausted, the code recognition processor 1 switches to position 0 and the central control panel 9_ detects an attack state. The current source .11 furthermore enables a code keyboard 14 to be connected to the processor 1. Access conditions can be changed directly by the apartment owner.
Die bereits beschriebenen Ausgestaltungen der Erfindung machen lediglich einseitige Datenübermittlung möglich, u.z. von Kodeerkennungsprozessoren 1. zum Zentralsteuerpult 9_. Eine höhere Stufe, vom Standpunkt der Benutzer aus gesehen, stellt eine Ausfertigung dar,in der das Zentralsteuerpult 9_ mit einem Modem 1J5 für beidseitige Datenübertragung ausge¬ stattet ist und die Wohnungen nach der Wahl der Benutzer gleichfalls mit solchen Modems 35 ausgestattet sind. Dieses kompexe Sicherheitssystem nach Fig. 3 ermöglicht, daß ei¬ nerseits das Zentralsteuerpult 9. die Art der gemeldeten Störung unterscheidet, und andererseits Regulationsangriffe in einzelnen Wohnungen direkt am Zentralsteuerpult 9_ ge¬ tätigt werden können, z.B. Lufttemperatur- oder -feuchtig- keitsregulierung. Die beidseitige Datenübertragung verläuft mit Schwingungszahlen von 5 bis 29 MHz.The configurations of the invention already described make only one-sided data transmission possible, uz from code recognition processors 1. to the central control panel 9_. A higher level, from the point of view of the user, is a version in which the central control panel 9_ is equipped with a modem 1J5 for data transmission on both sides and the apartments are also equipped with such modems 35, at the user's choice. This compact security system according to FIG. 3 enables the central control panel 9 to differentiate the type of the reported fault and, on the other hand, regulatory attacks in individual apartments can be carried out directly at the central control panel 9_, for example air temperature or humidity regulation. The two-sided data transmission runs with oscillation numbers from 5 to 29 MHz.
Das Sicherheitssystem zeichnet sich durch eine relativ gro¬ ße Angriffsbeständigkeit aus. Bei einem Versuch, die feh¬ lende Schwingungszahl durch ihre Emulation zu erstzen, genügt eine geringe Unterbrechung vor Einschaltung des Emu¬ lators, und das Zentralsteuerpult £ nimmt den Angriff wahr und ermittelt das angegriffene Objekt. Beim Ausfall der Netzspannung bleibt bei der elementaren Ausführung des Sys¬ tems seine Funktionsfähigkeit erhalten. In den Wohnungen, in denen die Zentrale an eine Stromquelle ri angeschlossen ist, wird beim Stromausfall die Ersatzstromquelle .13. einge¬ schaltet. Nachdem die Ersatzquelle 1 erschöpft ist, nimmt das Zentralsteuerpult eine Änderung des Gleichgewichtzu¬ standes wahr.The security system is characterized by a relatively high resistance to attack. If an attempt is made to replace the missing number of oscillations with its emulation, a slight interruption before the emulator is switched on is sufficient, and the central control panel £ perceives the attack and determines the object under attack. In the event of a mains voltage failure, the functionality of the elementary system is retained. In the apartments in which the control center is connected to a power source ri, the backup power source becomes the source of a power failure .13. switched on. After the replacement source 1 has been exhausted, the central control panel perceives a change in the state of equilibrium.
Im Falle, daß das Schlüssel, d.h. die Karte mit integrier¬ tem Chip, verloren geht, meldet der Benutzer den Verlust beim Bediensteten am Zentralsteuerpult 9., und dieser stellt einen geänderten Kode im Kodeerkennungsprozessor 1. der be¬ treffenden Wohnung ein. Wenn die Wohnung mit einer Kode- Tastatur r4 ausgestattet ist, kann selbst der Benutzer die- - lö ¬In the event that the key, ie the card with an integrated chip, is lost, the user reports the loss to the operator at the central control desk 9, and the latter sets a changed code in the code recognition processor 1 of the apartment in question. If the apartment is equipped with a r4 code keyboard, even the user can - solve
se Änderung vornehmen.Make this change.
Das Sicherheitssystem erlaubt, daß einzelne Punkte des Sy¬ stems, seien es auch die benachbarten, ganz unterschiedli¬ che Ausgestattung haben - von der elementaren bis zur kom¬ pletten. The security system allows individual points of the system, even the neighboring ones, to have very different configurations - from the elementary to the complete one.
