The inventive method consists in determining the state and the modification of the state for each object by means of an alarm system, in forming a control-diagnostic and alarm messages containing the object address and in converting said messages into hopping signals, in receiving the hopping signals transmitted by the alarm system of a protected object by one or several alarm systems of other protected objects of said group which are located within the range of capability limits of the alarm system device which transmits the hopping signals, in processing a hopping message contained in the received hopping signal with the aid of the alarm systems used in the form of hopping signal repeaters, in selecting a notification from the hopping message, in converting it into a standard message, in transmitting said message to the console terminal of a centralised protection guard station by means of a telephone network and /or a standard mobile communication cellular network, in selecting notifications from the processed received standard messages and in displaying them in a representative style. The inventive method makes it possible to simplify the centralised system for protecting a group of objects by avoiding the necessity of deploying base stations and repeaters for a regional mobile communication cellular network and to ensure the operation in the conditions of intentional interferences produced by penetrators by means of jammers.

Description

 The method of centralized protection of a group of objects

The invention relates to a technique for alarming and is intended for use in the implementation of centralized protection of real estate (residential premises, offices, garages and other objects) with the help of security equipment that works under certain adverse conditions, for example, when penetrating, attempting to penetrate or during unauthorized exposure and realizing alarming by means of a multi-channel notification system (STI).

Known technical solutions for the provision of alarm, providing in normal situations, the transmission of notifications from detectors installed at security facilities to a central monitoring station (CMS) through object terminals and through communication channels with the monitoring station.

In the alarm system of the patent RU 2069055 Cl, G 08C 13/00, 10.11.1996, security detectors are used, a security device made in the form of a code lock, an STI transmitter with an encoder-timer, as well as a personal receiver and a central receiver connected to the radio transmitter control center, the last of which is performed with a computer having an input adapter board and a remote terminal device in the form of a standard radio station.

The disadvantages of the known technical solutions are determined by the complexity, high cost (only the object equipment costs at least several hundred $ US) and the low reliability of the radio transmitting equipment installed on the guarded objects. To ensure a sufficiently large coverage area, this equipment emits a powerful (of the order of several watts) signal. This interferes with radio-electronic operating in the system coverage area. means, which limits the practical application of such a system.

The fact is that, in accordance with the requirements of state communications agencies, the maximum radiation power of a security alarm system, which does not require special permits for the purchase and operation of this tool in communication supervision agencies, is limited. In particular, in Russia it is limited to 10 mW (with an allowable frequency range of 433.92 M Hz ± 0.2%), which corresponds to a maximum range of 1-2 km. In a similar alarm system according to RU patent

2182088 Cl, B60 R 25/10, 05/10/2002 from the monitoring station of the data collection and processing center automatically monitor the serviceability of the radio channel by monitoring the periodic receipt of notifications from each object terminal device of the protected object, while radio communication is carried out using a microcellular data network (MRTD) ), containing base stations and repeaters, configured to receive code messages from object terminals, select and relay these messages to the nearest base station ntsiyu or repeater. The use of MRTDs, on the one hand, is the advantage of this technical solution (low radiation power and, therefore, simplicity and accessibility of subscriber equipment), and, on the other hand, causes a drawback, which manifests itself the more, the greater the required coverage area of the security system. It consists in the need to increase the number of ground-based relay devices (base stations and repeaters) in proportion to the coverage area. This complicates the infrastructure of the system, increases its cost and creates problems of the organizational and technical plan. Since the frequency resource allocated for civilian use is very limited, for deploying MRTDs on the ground, it is necessary to obtain permission from the relevant departments to use land for installation of base stations and repeaters, as well as permission to use the frequency resource. In addition, the operator operating the ISMT must have licenses for data services and telematic services. For most of the allowed frequency ranges, obtaining permission to use frequencies to create a network is possible only on a competitive basis. Moreover, the more repeaters and base stations are used in the system, the more difficult it is to fulfill the requirements for electromagnetic compatibility with other electronic means.

In this regard, in practice, only a small number of the most economically powerful enterprises, as a rule, having experience operating geographically distributed networks, are able to fully deploy MRTDs.

In the radio-channel system for collecting and processing information for centralized protection of a group of objects according to patent RU Ш2198800 Cl, В 60 R 25/00, В 60 R 25/10, 02.20.2003, notifications about the status of protected objects and about changes in these states are generated and transmitted through channels a telephone network, such as a public switched telephone network (PSTN), over a standard cellular mobile network, such as GSM, and over MRTDs, at territorially distributed relay nodes of MRTDs, these notifications are received, selected and relayed over the air and / or over wire communication channels, in the data collection and processing center, the remote terminal device is connected via a central radio modem to a standard cellular network mobile communications, and the TTT TR information input adapter receives messages from the telephone network.

This system uses the capabilities of existing communication networks in the region — standard cellular mobile network and telephone network, such as PSTN, for data transmission, which can significantly reduce the required number of MRTD repeaters.

However, the use of alarm systems in it operating in a narrow frequency range of 433.92 M Hz ± 0.2% with an allowable radiation power of up to 10 mW significantly limits the throughput (the number of simultaneously tracked objects) and reduces the noise immunity of the system. The use of a standard mobile cellular network, for example, the GSM standard, for transmitting code messages does not eliminate the above limitations, since standard mobile cellular networks are very vulnerable to intentional (intentional) interference that an attacker can use. So, according to the advertising information of the Israeli company NetLipe, a jammer mass-produced by this company

C-Guard LP is able to block cellular communications for almost all currently used standards: - analogue: AMPS, N-AMPS, NMT, TACS;

- digital: GSM, CDMA, TDMA, iDEN, UMTS in all frequency ranges they use.

With an average radiation power of 5-50 mW and a mass of not more than 0.6 kg, this jammer provides effective blocking of subscriber terminals of standard cellular mobile networks in a radius of 5 - 80 m around itself.

To increase the throughput and to increase the noise immunity of the SPI, the technical solution according to the patent is directed RU 2231458 Cl, 60 R 25/00, 06/27/2004, selected as the closest analogue of the present invention.

A positive effect is achieved in it, due to the combination of the components of the aforementioned communication systems within a single SPI, using various types of object and relay equipment while maintaining the centralization of data collection and processing. Such a construction makes it possible to vary the look of SPI depending on the capabilities of users and system operators, optimizing in each case the “cost / effectiveness” ratio and providing the ability to send notifications to the information collection and processing center even when deliberate deliberate interference is created by the attackers.

To do this, using the security alarm settings installed on the guarded objects, determine the state of each guarded object and change this state, generate control and diagnostic and alarm notifications, convert them into messages that carry the indicated notifications, which are transmitted over the telephone network via a standard mobile cellular network communication, according to a specialized MRTD and using the so-called horpip-signals - sequences of radio pulses with a carrier part that varies according to the pseudo-random law the one that carry notifications about the status of protected objects and about changes in these states, receive all these messages in the information collection and processing center, process them, as a result of which notifications are issued, and display them in a form convenient for human operator to perceive .

However, the deployment of this system also requires financial investments in infrastructure and the availability of permits for the operator company to deployment of relay nodes and construction works in the area, as well as permissions to use the necessary frequency resource. This significantly limits the scope of the practical application of this method of transmitting notifications, making it available only to a very limited circle of large operating companies.

The objective of the present invention is to simplify the practical implementation of the known method for centralized protection of a group of objects using horpig signals and a regional cellular mobile communication network, by eliminating the need to deploy base stations and repeaters on the ground. It is assumed that the implemented IPS should provide information to a centralized security point serving a geographically distributed group of objects, for example, an apartment and a garage for one individual user, a cottage village, etc.

The problem is solved in that in the method of centralized protection of a group of objects, according to which, using the security alarm settings installed on each guarded object, the state of the guarded object and changes in this state are determined, the corresponding control and diagnostic and alarm notifications containing the address of the guarded object are formed, they are converted to horror messages that are transmitted using a transmission system using horror signals with a changing carrier frequency, and to standard messages Nia, who sent using the telephone network and / or a standard cellular mobile communication network, receiving standard messages in paragraph centralized protection on a console terminal connected to the central monitoring, carry out the processing of standard messages, As a result of which the notices contained in them are highlighted and the notifications received are displayed in a form convenient for the human operator to perceive, the hormp signals transmitted by the security alarm installation of some protected object in the group are received by one or several security alarm settings of other protected objects from this groups that are within the range of the transmission system of the security alarm installation that transmitted the horpg signal process the horpg message containing I in the received horpig signal, as a result of which a notification is extracted from the horpip message and converted into a standard message to be transmitted via telephone network channels and / or via a standard mobile cellular network to a central terminal of a central security guard. The technical result provided consists in the creation of such a technology for transmitting notifications that does not require the deployment of a specialized network of relay points and base stations on the ground and at the same time allows working in conditions of intentional interference intentionally created by attackers using jammers.

The invention is illustrated using the drawings shown in Fig.l and Fig.2.

Figure l presents a functional diagram of the used alarm systems, and figure 2 shows the general structure of the security system for implementing the proposed method, explaining the concept of the used notification transmission when protecting a group of objects. In Fig. L and Fig. 2, the following are marked: alarm settings 1.1, 1.2, ..., l .N, alarm detector unit 2, controller 3, first GSM mode 4, terminal object device 5, horror signal transmitter 6 , receiver 7 of the horror signal, antenna switch 8, central security point 9, remote terminal 10, second GSM modem 11, PLSC 12, telephone modem 13.

The shading in Fig. 1 shows the components of the security alarm system that are part of those security alarm systems that perform the relay function. This function is endowed with the alarm settings 1.1 and LN shown in Fig. 2 (they are connected to the GSM network and to the telephone network). And the installation 1.2 of the security alarm system shown in FIG. 2 does not perform the relay function. Unshaded components must be included in each of the 1.1-LN burglar alarm installations. Shown in FIG. 1, one of the 1.1-LN alarm systems configured for relaying contains a controller 3, to the inputs of which are connected a block 2 of security detectors and a receiver 7 of a horror signal, and to the output is a GSM modem 4, configured to transmitting SMS messages over a GSM network, a terminal object device 5 configured to transmit messages over a standard telephone network, for example via PSTN, and a horror signal transmitter 6, the output of which is connected to the input of the antenna switch 8, configured to the transmission and reception over the air of the horpig signal, while the output of the antenna switch 8 is connected to the input of the receiver 7 of the horpg signal.

Block 2 security detectors is a technical means of burglar alarms for detecting intrusion, attempted entry into a protected object or physical (unauthorized) exposure to it in excess of the normalized level, and the formation of the corresponding alarm notification. Security detectors can also generate control and diagnostic notifications. The system that implements the claimed method of protecting a group of objects contains 1.1-LN alarm systems, each of which is installed on the corresponding property, and paragraph 9 of the centralized security. Real estate on which installations 1.1-1 are installed. N security alarms, located close to each other and form a geographically distributed group (for example, a cottage village). At least two of the installations 1.1-1. N security alarms, for example, settings 1.1 and lN, have a relay function, that is, they can be used to relay to central protection point 9 standard messages transmitted from alarm 1.1-LN settings in the form of horror messages using a transmission system using signals from changing carrier frequency - horpip signals. To provide the relay function, the alarm settings 1.1 and LN are configured not only to emit a horror signal, but also to receive a horror signal, process it, select the notifications contained in it, and convert them to standard messages (for example, in SMS messages) for transmission over the GSM network and over the telephone network.

The central security point 9 contains a remote control terminal device 10 connected to the GSM modem H _{5 of the} monitoring station 12 and the telephone modem 13. The GSM modem 11 is configured to receive standard messages from the 1.1-LN alarm systems via a standard cellular mobile network, for example via GSM networks. The telephone modem 13 is configured to receive standard messages over the telephone network, for example via PSTN.

Terminal object devices 5 of installations 1.1 and LN of the burglar alarm and the remote terminal device 10 of the central security point are components of the IPS.

As can be seen from Fig. L and Fig. 2, in the considered circuits, SPI repeaters in the form in which they are present in the prototype are absent. Their role is played by the 1.1 and LN burglar alarm installations, which have a relay function and are located at other guarded objects that are part of the guarded objects group. To fulfill this role, they included horror signal receivers 7 and antenna switches 8. At the same time, a standard cellular network is used, as well as in the prototype, to transmit messages to a remote central security point 9, located outside the horror signal reception zone mobile communications, such as a GSM network and / or telephone network, such as PSTN.

The terminal part of the SPI is the console terminal device 10, which is part of paragraph 9 of the centralized security. Via the GSM modem 11 via the GSM network and via the telephone modem 13 via the standard telephone network, the handheld terminal device 10 receives messages containing the control and diagnostic and alarm notifications sent by the alarm settings 1.1 and LN.

The controller 3 shown in FIG. 1 is a control and reception device. That is, it is a technical means of burglar alarms, designed to receive notifications and issue notices for direct human perception, and for further transmission of notices through various terminal object devices SPI. AND

As the terminal object device 5, which provides the transmission of messages over the telephone network, the “Device terminal Reef Bastion-1” serial produced by the applicant company can be used, which is used for generating and transmitting messages on busy telephone lines from the device of the object “Vista” and the like (catalog “Radio-channel security systems)), Moscow, 000“ Altonika)), 2003, p.15). Moreover, the role of the telephone network can be played by PSTN.

As a GSM modem 4, the GS35 module Thermal of the Siemens company can be used. To connect to other devices, it uses the standard RS-232 interface. This technical solution is applied, in particular, in the REEF GSM-1000 terminal mobile cellular communication equipment commercially available by the applicant enterprise). The antenna switch 8 used in the 1.1 and l.N alarm systems is a standard element of microwave technology.

As a transmitter 6 of the hornpig signal, an autonomous transmitting device for the IPA “APKAH” (www.arkap.srb.sh) commercially available by the applicant company can be used. A direct analogue of the transmitter of the h-signal is used in the commercially available security alarm system "RIF STRING RS -202".

The receiver 7 of the horpig signal was implemented by the applicant enterprise in the form of prototypes and successfully passed field tests.

The composition and principles of operation of the receiver 7 of the horror signal and the transmitter 6 of the horror signal are not the subject of this invention. They are described in detail, for example, in the descriptions of inventions to patents DE 4337211 G 08 B 25/10, 12/15/1994; EP 0651361,

G 08 B 25/10,03.05.1995. The remote control terminal device 10 and the monitoring station 12 are implemented by the applicant company in the mass-produced equipment of the radio-channel security alarm “RIF CTPING-200”

(RU 2198800, 60 R 25/00, 02/20/2003; RU 2201363, 60 R 25/10, 03/27/2003).

The GSM modem 11, like the telephone modem 13, are standard nodes of telephone networks, respectively, mobile and fixed communications.

Thus, all the blocks used in the above structure for the implementation of the claimed method are commercially available products available on the commercial market, and a significant part of them are produced and sold by the applicant company.

The claimed method of centralized protection of a group of objects is as follows.

Security detectors, which are part of block 1 of security detectors, which is a mandatory part of each of the installations 1.1-1. N security alarms (Fig. L and Fig. 2) installed at the guarded real estate object form either alarming or control and diagnostic notifications. The generation of alarm notices is caused by unauthorized actions on the property (for example, breaking a door, window or roof). The control and diagnostic notifications fulfill a service role in the STI (for example, they can be formed during periodic monitoring of the operation of detectors). These alarming or control and diagnostic notifications come through one or several channels (loops) to controller 3. In the controller 3 of the alarm and control and diagnostic notifications are formed:

- standard message for transmission over the GSM network;

- standard message for transmission over the telephone network; - Horror message for transmission using horror signal.

The first of these standard messages is sent to the input of the terminal of a standard cellular mobile network, in this case, to the input of the GSM modem 4, the second standard message is sent to the input of the object terminal device 5, and the message is sent to the input of the transmitter 6 of the signal. In each standard message and in the horpip message, the address code of the protected object is entered.

Further operations carried out with the indicated standard messages after their transmission and subsequent reception in clause 9 of the central guard are related to the processing of the received notifications, their display in a form convenient for human operator to perceive, and the implementation of appropriate protective measures if necessary.

When considering, however, the possibility of counteracting the operation of installations 1.1-1 was not taken into account. N burglar alarm. The simplest and most accessible countermeasures for attackers are deliberate violation of the telephone line, for example, by damaging the incoming telephone cable and setting up a deliberate interference with cellular mobile networks using a jammer like the aforementioned C-Guard LP. In this case, the possibility of transmitting an alarm message is provided using a horror signal, which is characterized by a high degree of noise immunity. In accordance with the idea of the invention, the role of horpig signal repeaters is assigned to several of the 1.1-LN alarm systems located at the guarded real estate objects in the group, for example, to the settings 1.1 and 1.N For this, a receiver 7 is introduced into each of these several alarm systems horror signal and antenna switch 8. These alarm systems should also include a GSM modem 4 and terminal object device 5. Alarm systems installed on other protected objects kmax this group, may contain only those blocks which the conditioned image on fig.l not shaded.

Antenna switch 8 according to the signal generated by the transmitter 6 of the horpip signal, if necessary, transmitting the horpip message using the horpip signal, connects the transceiver antenna to transmit the horpg signal. At other times, the antenna switch 8 connects the antenna to receive a horpip signal. If the antenna switch 8 is not included in this security alarm installation, for example, installation 1.2, then the antenna of this security alarm installation will be an element of the horror signal transmitter 6, performing only the functions of the transmitting antenna.

The Noripg signal, as it were, “carries out” an alarm notification from the zone of lack of cellular communication (or telephone communication) to the zone in which this communication is possible.

The smallest possible number of horpig signal repeaters for this group of real estate is equal to two. At least one of the installations 1.1-1 must be in the coverage area of the horror signal transmitter 6 located at each property included in the group under consideration. N burglar alarm performing repeater functions. That is, the horpip signal of any transmitter 6 (including the transmitter 6 included in the security alarm system, which functions as a repeater) must be received by one of the receivers 7 of the horpip signal. This condition is briefly indicated in the technical literature as the formation by transmitters 6 and receivers 7 of a horror signal of a “field of horror signal”.

As the tests of the RS-202 product mentioned above, conducted by the applicant enterprise, have shown, it is now possible to ensure the transmission of notifications using a horpig signal over a range of about 5-10 km. Taking into account that the effective range of the C-Guard LP type jammer (and the like) is only 5 - 80 m, it is obvious that when within a radius of several kilometers from the protected object under consideration at least one protected object with a security alarm system with reception capabilities horror signal and subsequent relay (via standard mobile cellular network and / or telephone network channels), the use of deliberate interference by intruders and damage to the telephone line will not prevent I send an alarm notification to paragraph 9 of the central guard.

The transmitter 6 of the horror signal provides the transmission of sequences of radio pulses at the "jumping" carrier frequencies. These sequences of radio pulses carry a horror message about the state of the protected object or about a change in this state. The presence of a “jumping” carrier frequency makes it difficult for attackers to counteract the transmission of a horpip signal. The probability of suppressing a horpip signal after just its third repetition (at different carrier frequencies) is practically zero. On the other hand, horror-signal is freely received by a special receiver 7 horror-signal, which is part of the alarm system, which serves as a repeater. Extracted from the horror signal horror messages are transmitted from the receiver 7 horror signal to the controller 3.

Controller 3 converts the horpg messages to standard messages, the format of which allows transmission over a standard cellular mobile network, for example, over a GSM network. As shown in FIG. 1, these messages are received by the GSM modem 4 and broadcast by it, for example, in the form of short SMS messages widely used in cellular telephony.

If the security alarm installation that has received the horror signal is connected to the PSTN, then the controller 3 sends standard messages in the appropriate format to central security point 9 and via the PSTN through the object terminal device 5 (if the telephone line is not broken).

Standard messages transmitted in the form of SMS messages are received in paragraph 9 of the central security by the terminal 10 via the GSM modem 11 and transmitted to the monitoring station 12. Since the GSM networks of large regional cellular communication operators almost completely cover the territories of the regions they control, and with With the help of roaming, global communication services are made available to users; central security point 9 can be located anywhere in the territory served by this mobile operator. Sustainable communication with protected objects is guaranteed by contractual obligations. In this situation, the ability of attackers to use powerful directors of interference to cellular networks mobile communications, blocking communications in large areas, seems unlikely.

Standard messages transmitted via PSTN arrive at the remote terminal 10 through a telephone modem 13 and are then transmitted to the monitoring station 12.

In the opposite direction — from the monitoring station 12 through the handheld terminal device 10 and then either through the GSM modem 11 or the telephone modem 13 — service messages addressed to various external subscribers, for example, police on-call units (external subscribers in FIG. L and FIG. .2 not shown).

Other operations performed in the monitoring station 12 and not directly related to the operation of the SPI are typical.

Thus, even when attackers use interference by the cellular mobile networks and intentionally violate the telephone channel, the SPI used in the claimed method will ensure the transmission of alarm notifications to central security point 9, without requiring any financial and organizational efforts to create a specialized relay network. From the foregoing, it follows that the claimed method of centralized protection of a group of objects can significantly expand the scope of practical application of SPI using a horpig signal, as well as standard networks of regional mobile cellular operators, and make them accessible to individual users. New technology for the transmission of notifications from installations 1.1-1. N burglar alarms in clause 9 of the centralized guard do not require the deployment of a specialized network of relay points on the ground and allows working in the conditions of use by intruders intentional interference. This technology is implemented using commercially available technical means, tested in practice.
