Description

Predmetni izum se nanaša na alarmni sistem, sestavljen iz javljalne centrale, npr. vlomne oz. požarne alarmne centrale, in nadzornega centra, med katerima se s pomočjo trajne in neprekinjene povezave, npr. preko LAN, WAN ali javnega internetnega omrežja in npr. TCP/IP protokola, dvosmerno prenaša digitalne in analogne podatke.The present invention relates to an alarm system consisting of a call center, e.g. burglary or fire alarm panels, and a control center between which, by means of a permanent and uninterrupted connection, e.g. via LAN, WAN or public Internet network and e.g. TCP / IP protocol, transmits two-way digital and analog data.

Znanih je več alarmnih sistemov uvodoma navedene vrste, a nobeden izmed njih ne ustreza. Znane naprave so po eni strani enonamenske, predvidene izključno za povezavo znotraj sistema istega proizvajalca. Po drugi strani pa niso zmožne sprejemati standarnih signalov za prenos alarmnih sporočil iz vlomnih oz. požarnih alarmnih central, jih varno posredovati nadzornemu centru in pri tem zaznati vsakršno in takojšnjo prekinitev. Pomanjkljivost znanih naprav je tudi odsotnost zmožnosti dvosmernega prenašanja individualnih logičnih ali analognih signalov.Several alarm systems are known for the types mentioned above, but none of them are suitable. Known devices are, on the one hand, single-purpose, intended exclusively for connection within the same manufacturer's system. On the other hand, they are not capable of receiving standard signals for the transmission of alarm messages from burglaries. fire alarm panels, safely forward them to the control center, detecting any and all interruptions immediately. A disadvantage of the known devices is the absence of the ability to transmit individual logical or analog signals bidirectionally.

Naloga izuma je ustvariti alarmni sistem, ki omogoča trajen in neprekinjen nadzor ter povezavo med npr. vlomno oz. požarno alarmno centralo in nadzornim centrom, pri čemer se vsakršno prekinitev evidentira v vnaprej določenem času.It is an object of the invention to create an alarm system which enables continuous and continuous monitoring and connection between e.g. burglary or. the fire alarm panel and the control center, each break being recorded within a predetermined time.

Zastavljena naloga je po izumu rešena tako, da je med javljalno centralo in nadzornim centrom nameščen komunikacijski modul, ki iz javljalne centrale prihajajoče signale digitalizira in preko ustreznega omrežja pošlje nadzornemu centru v nadaljnjo obdelavo. Nadzorni center izbiroma posreduje omenjene signale vsaj enemu osebnemu računalniku, kjer se signale obdela in na osnovi tega ustrezno ukrepa. Pri tem nadzorni center in komunikacijski modul zaznavata prekinitev povezave preko omrežja v poljubno nastavljivem časovnem obdobju.The task according to the invention is solved by placing a communication module between the control panel and the control center, which digitizes the incoming signals from the control panel and sends it to the control center for further processing through the appropriate network. The control center optionally transmits said signals to at least one PC where the signals are processed and acted upon accordingly. In this case, the control center and the communication module detect the disconnection of the network over an arbitrarily adjustable period of time.

Pri tem je po izumu predvideno, da komunikacijski modul obsega vsaj mikrokontroler, ki preko mrežnega vmesnika in omrežja nadzornemu centru posreduje signale, ki jih je prejel iz javljalne centrale in izbiroma ustrezno pretvoril. V določenih primerih, kot npr. pri alarmnih centralah, pa je zaželeno in potrebno, da komunikacijski modul nadalje obsega analogni element z emulacijo telefonske linije, v katerega sta speljana analogna oz. digitalna telefonska linija za varnostno povezavo z nadzornim centrom, in signal iz javljalne centrale. Omenjenemu analognemu elementu je pri tem zaporedno prigrajen analogno digitalni pretvornik, sestoječ iz sprejemnika signalov po standardnih protokolih za prenos signalov, npr. ContactID protokolu, prihajajočih iz javljalne centrale, in generatorja tonov. Sprejemnik in generator tonov sta pri tem medsebojno vzporedno povezana.According to the invention, it is envisaged that the communication module comprises at least a microcontroller which, through the network interface and the network, transmits to the control center the signals received from the control panel and optionally converted. In certain cases, such as In the case of alarm panels, it is desirable and necessary for the communication module to further comprise an analog element by emulating a telephone line into which the analogue and / or telephone lines are connected. digital telephone line for security connection to the control center, and signal from the control panel. Said analogue element is sequentially fitted with an analog-to-digital converter consisting of a signal receiver according to standard signal transmission protocols, e.g. ContactID protocol coming from the call center and tone generator. The receiver and the tone generator are connected in parallel.

Po izumu je tudi predvideno, da mikrokontroler nadalje obsega mrežni vmesnik z enkripcijo in poljubno število napetostnih izhodov ali kontaktnih izhodov kot npr. vhodni vmesnik, na katerega se da speljati poljuben vhodni signal, ter izhodni vmesnik, iz katerega se da speljati izhodni signal za krmiljenje različnih naprav.The invention further provides that the microcontroller further comprises a network interface with encryption and any number of voltage outputs or contact outputs such as e.g. an input interface to which any input signal can be output, and an output interface from which an output signal can be output to control various devices.

Alarmni sistem s komunikacijskim modulom po izumu se da uporabiti za različne alarme, krmiljenje na daljavo, npr. centralne kurjave in vklop/izklop določenih naprav, spremljanje parametrov na daljavo, telemetrijo, npr. nadzor temperature, tlaka, stanje oz. stopnjo odprtosti vrat.An alarm system with a communication module according to the invention can be used for various alarms, remote control, e.g. central heating and switching on / off of certain devices, monitoring of parameters remotely, telemetry, e.g. control of temperature, pressure, condition or. the degree of openness of the door.

Alarmni sistem po izumu, kot je prikazan na sl. 1, sestoji iz javljalne centrale 1, npr. vlomne oz. požarne centrale, ki je preko komunikacijskega modula 2 in s pomočjo trajne in neprekinjene povezave 3, kot npr. LAN, WAN ali javnega internetnega omrežja, ki deluje po npr. TCP/IP protokolu, povezana z nadzornim centrom 4. Vsakokratni nadzorni center 4 lahko sočasno sprejema digitalne in/ali analogne signale iz več komunikacijskih modulov 2, ki jih nato preko npr. običajnega vmesnika RS323 posreduje v nadaljnjo obdelavo, npr. na vsaj en osebni računalnik 5, na osnovi česar se ustrezno ukrepa.The alarm system of the invention as shown in FIG. 1, consists of a call center 1, e.g. burglary or fire control panel, which is via communication module 2 and through a permanent and uninterrupted connection 3, such as. LAN, WAN, or public Internet network that works by e.g. TCP / IP protocol associated with the control center 4. Each control center 4 can simultaneously receive digital and / or analog signals from several communication modules 2, which can then be transmitted through e.g. forward the normal RS323 interface for further processing, e.g. to at least one PC 5, and action is taken accordingly.

Komunikacijski modul 2, ki je na sl. 2 prikazan obdano s črtkano črto, obsega analogni element 6 z emulacijo telefonske linije, v katerega sta speljana analogna oz. digitalna telefonska linija 7 za varnostno povezavo z nadzornim centrom 4 in signal 8 iz javljalne centrale 1. Omenjeni analogni element 6 je zaporedno povezan z analogno digitalnim (A/D) pretvornikom 9, ki je na sl. 2 prikazan obdano s črta-pikčasto črto, in sestoji iz sprejemnika 10 signalov po standardnih protokolih za prenos signalov, npr. OontactID protokolu, prihajajočih iz javljalne centrale 1, in generatorja 11 tonov, pri čemer sta sprejemnik 10 in generator 11 medsebojno povezana vzporedno. A/D pretvorniku 9 je zaporedno priključen mikrokontroler 12, ki obsega mrežni vmesnik 13, prednostno Ethernet vmesnik z npr. AES enkripcijo, ter vhodni vmesnik 14 in izhodni vmesnik 15. Mrežni vmesnik 13 je nadalje povezan s trajno in neprekinjeno povezavo 3, kot npr. LAN, WAN ali javnim internetnim omrežjem, ki deluje po npr. TCP/IP protokolu, in naprej z nadzornim centrom 4, kot že omenjeno zgoraj. Na vhodni vmesnik 14 je po izumu mogoče speljati poljuben vhodni signal 16, npr. z različnih stikal, tipal, ipd. Iz izhodnega vmesnika 15 je po izumu mogoče speljati izhodni signal 17 za krmiljenje različnih naprav, npr. prižiganje alarmne luči, dvig ali spust zapornice, odpiranje in zapiranje vrat, ipd. Vsakokratni element komunikacijskega modula 2 je pri tem s pomočjo napajalnika 18 ustrezno oskrbovan z električno energijo (na sl. 2 prikazano s črtkanimi puščicami).The communication module 2 of FIG. 2 is shown surrounded by a dashed line and comprises an analog element 6 emulating a telephone line into which an analog or a line is connected. digital telephone line 7 for security connection to the control center 4 and signal 8 from the control panel 1. Said analogue element 6 is connected in series with the analog to digital (A / D) converter 9 in FIG. 2 is shown surrounded by a dotted line and consists of a signal receiver 10 according to standard signal transmission protocols, e.g. OontactID to the protocol coming from call center 1 and generator 11, the receiver 10 and generator 11 being connected in parallel. A / D converter 9 is a sequentially connected microcontroller 12 comprising a network interface 13, preferably an Ethernet interface with e.g. AES encryption, as well as input interface 14 and output interface 15. Network interface 13 is further coupled to a permanent and continuous connection 3 such as e.g. LAN, WAN, or public Internet network that works by e.g. TCP / IP protocol, and further with Control Center 4, as mentioned above. According to the invention, any input signal 16 can be connected to the input interface 14, e.g. from various switches, sensors, etc. According to the invention, an output signal 17 can be output from the output interface 15 for controlling various devices, e.g. switching on the alarm light, raising or lowering the barrier, opening and closing doors, etc. Each element of the communication module 2 is thus properly supplied with power via the power supply 18 (shown in dashed arrows in Fig. 2).

Kadar je povezava komunikacijskega modula 2 z nadzornim centrom 4 vzpostavljena in neprekinjena, pošlje mikrokontroler 12 preko mrežnega vmesnika 13 in npr. internetnega omrežja 3 signal v nadzorni center 4, ki sprejme omenjeni signal. V nadzornem centru 4 se omenjeni prejeti signal preko ustreznega vmesnika, npr. RS232, v nadaljnjo obdelavo pošlje npr. na osebni računalnik 5. Po ustrezni obdelavi prejetega signala se odloča o morebitnih ukrepih.When the connection of the communication module 2 to the control center 4 is established and uninterrupted, it sends the microcontroller 12 via a network interface 13, e.g. internet network 3 signal to the control center 4 that receives said signal. In control center 4, said received signal is transmitted via a suitable interface, e.g. RS232, send for further processing e.g. 5. After appropriate processing of the received signal, it is decided on possible measures.

Kadar je povezava komunikacijskega modula 2 preko omrežja 3 z nadzornim centrom 4 prekinjena, se vsi morebitni dogodki shranjujejo v mikrokontrolerju 12. Nadzorni center 4 pri tem zazna prekinitev omrežja 3 in preko ustreznega vmesnika, npr. RS232, pošlje ustrezno informacijo na npr. na osebni računalnik 5, kjer se zadevno informacijo ustrezno obdela in odloči o morebitnih ukrepih. V takšnem primeru se samodejno aktivira analogna oz. digitalna telefonska linija 7 za varnostno povezavo, preko katere poteka komunikacija z nadzornim centrom 4, dokler ni ponovno vzpostavljena povezava preko omrežja 3. Ko je povezava med komunikacijskim modulom 2 in nadzornim centrom 4 ponovno vzpostavljena, pošlje mikrokontroler 12 iz pomnilnika vse dogodke preko omrežja 3 nadzornemu centru 4, kjer se omenjene prejete signala preko ustreznega vmesnika, npr. RS232, v nadaljnjo obdelavo pošlje npr. na osebni računalnik 5. Po ustrezni obdelavi prejetega signala se odloča o morebitnih ukrepih.When the communication module 2 is disconnected from the network 3 to the control center 4, all eventual events are stored in the microcontroller 12. The control center 4 detects the interruption of the network 3 and through the appropriate interface, e.g. RS232, sends relevant information to e.g. to a PC 5 where the relevant information is properly processed and to decide on possible actions. In such a case, the analogue and / or analog signals are automatically activated. digital telephone line 7 for the security link through which communication with the control center 4 is made until the connection via the network is restored 3. When the connection between the communication module 2 and the control center 4 is restored, the microcontroller 12 sends from memory all events via the network 3 control center 4, where said signals are received via a suitable interface, e.g. RS232, send for further processing e.g. 5. After appropriate processing of the received signal, it is decided on possible measures.

Vse dogodke se v nadzornem centru 4 obdela z ustrezno programsko opremo, ki ni predmet tega izuma in zato ni podrobneje opisana. Povezava preko omrežja 3 je pri tem vseskozi nadzorovana, pri čemer se vsak izpad povezave takoj zabeleži v nadzornem centru 4. Poleg tega so vsi podatki, ki se jih prenaša med komunikacijskim modulom 2 in nadzornim centrom 4 kriptirani, npr. po sistemu simetričnega ali asimetričnega ključa z najmanj 128 bitnim ključem, ki se ga po potrebi lahko menja neposredno preko nadzornega centra 4.All events in Control Center 4 are handled by appropriate software which is not the subject of this invention and is therefore not described in more detail. The connection via network 3 is monitored throughout, with any failure of the connection being immediately recorded in the control center 4. In addition, all data transmitted between the communication module 2 and the control center 4 is encrypted, e.g. by means of a symmetric or asymmetric key system with at least 128 bit key, which can be changed directly via the control center 4 if necessary.
