Description

The utility model relates to the field of burglar alarms and can be used in systems for transmitting and processing signals used to remotely monitor the status of stationary and mobile objects located in a wireless coverage area, including cellular communications.

There are many different degrees of complexity of remote protection devices for stationary and mobile objects over wireless networks, which widely use, including the GSM mobile communication system.

There is a method of burglar alarms and an electronic security device for implementing the method, the latter comprising an electronic device covertly located on a guarded object, incorporating intrusion detection sensors connected via a switching unit to a mobile phone. When at least one of the sensors is triggered, a call is initiated from a mobile phone to a pre-registered subscriber number to which a penetration alert should be sent (see RU patent No. 2170458 G08В 25/08, 07/10/2001).

This device can be used to protect both stationary and mobile objects and relates to budget systems that do not provide for centralized protection of a remote object. The main disadvantage of this device is the lack of protection against the so-called electronic warfare

(EW), which are currently available, including as commercially available products, in particular, the radio frequency noise generators “Barricade”, “Spectrum”, “C-Guard 300”, manufactured by CJSC “RUSSIAN SECURITY”, etc.

In the event of the impact of equipment of this kind on a known security system, the communication channel is blocked and notification of penetration into the protected object via a radio channel, in almost the entire frequency range, becomes impossible.

A security device is known that contains m fixed security alarm installations installed on guarded real estate objects comprising a block of stationary security detectors, a fixed object terminal device and an object relay node of a microcellular data network configured to receive code messages from stationary and transportable security alarm installations and from wearable object terminal devices, the selection of these messages and their transmission over a standard cellular network mobile communication, in the event of a signal from the sensor in violation of the protection circuit, generates an information package that is sent to the information collection and processing center (TsSiOI) and to the personal receiver of the owner via a wireless communication network (see patent RU No. 2201363, B60R 25/10 March 27, 2003).

Upon receipt of an alarm signal, the dispatch manager takes control of the facility and conducts the measures prescribed for the situation. It should be noted that in this protection method, the serviceability of the radio channel is monitored by tracking the periodic receipt of notifications. This allows you to detect channel malfunction and the appearance of interference at the operating frequency, which can be considered one of the ways to counter EW.

This device belongs to a group of fairly complex and expensive security systems, incorporating the so-called

Dispatch center (DC) or Central Intelligence Center, through which control over a number of remote objects is carried out.

The main disadvantage of this system is the presence in its composition of a technically sophisticated and costly central automation and control system, the organization of which entails significant material, technical and time costs, which is the main factor holding back the broad development of such systems. At the same time, the scope, by definition, is limited only to those regions where organized by the Center for Strategic Research and Development (subject to the prohibition of roaming services). Another negative factor is the significant delay introduced by the Center for the Protection of Information and Security, being an additional intermediate link in the chain of transmission of an alarm message from the object of protection to the owner.

A significant drawback is also the selected notification transmission technique for monitoring the operability of the communication channel, namely, the short message service (SMS). It is known that the speed of SMS delivery depends on many factors, including the loading of the short message server, which at peak times can cause notification delays of up to several hours. Moreover, a simple check of the communication channel does not provide reliable protection of the guarded object from attack using electronic warfare equipment.

Similar alarm systems are also known that eliminate the disadvantages of the previous system in terms of monitoring the health of the communication channel.

In particular, it is known that the signaling system for damage cases is closest to the utility model in terms of technical nature and the result achieved, which is configured to signal through existing radio networks and use frequencies and established normal operating modes of mobile radiotelephony equipment, which are located permanently in residential homes, etc. or mobile in vehicles, analyzers

alarm signals from alarm sensors with alarm sensors about damage cases, with alarm sensors such as glass break sensors, motion sensors, these alarm analyzers are capable of cyclic interrogation by the central station with a predetermined tact about their operability and ensuring the interrogation mode ready for use, and contain radio modems with connection modules for at least 3 residential units, as well as synchronous-serial interface devices I connect up to 4 devices that expand the capabilities of the alarm analyzer, respectively, up to 8 residential units each, and send an alarm through a radio modem to a receiving central station containing a central alarm location with a processing terminal and an alarm printing device, as well as a radio installation for 5000 ( expandable to 10000) alarms (see patent RU No. 2153193, G08B 25/10, 07.20.2000).

The central station, according to this invention, cyclically polls the status of alarm analyzers installed on stationary or mobile security facilities, i.e. checks cyclically whether the radio link is in order and whether the device answers the call correctly. When the alarm sensors are triggered, the corresponding alarm analyzer calls the central station and is processed in the order received. The communication parameters claimed in this invention for transmitting data on a radio channel, including the time to build and terminate a connection, are maximum 2 seconds, and the cycle cycle is set based on the number of subscribers served and is minimum 1 minute.

The main disadvantages of this system, inherent, as noted above, to all systems built on the principle of centralized management, are, firstly, the significant material, technical and time costs for organizing

dispatch center, and secondly, the limitation of the effective area of the system coverage area of the regional DC. In the latter case, the theoretical possibility of roaming service for security subscribers located in the coverage area of other mobile networks is not taken into account, since under such conditions operating costs for checking the communication channel increase significantly.

Another disadvantage of this system is the significant delay introduced by the central station, being an additional intermediate link in the chain of transmitting an alarm message from the object of protection to the owner.

It is important to note that the cyclic survey of subscribers to monitor the serviceability of the communication channel, being, in theory, an effective way to counter EW, in the conditions of centralized protection of mobile objects, practically loses its advantages. So, for example, with a cyclic survey of only 180 mobile subscribers (with the declared maximum possible 5000) with a minimum of 1 minute cycle, the system’s response to “jamming” the communication channel by electronic warfare equipment can be 3 hours in the worst case (without taking into account possible retries), which It can in no way be considered acceptable, not to mention the profitability of a system with such a small number of subscribers. The use of the system according to RU 2153193 for the protection of stationary objects, using the provided possibility of expanding the equipment (up to 35 subscribers per 1 radio modem of the alarm analyzer), also does not provide reliable protection, because when servicing about 500 subscribers (only 2 medium-sized apartment buildings, which is also economically not justified), the reaction time will be about 15 minutes, without taking into account the processing time and solution of the situation.

Finally, it is well known that with the development and expansion of the system with a corresponding increase in the total number of subscribers, reliability and

the stability of the firmware will be steadily decreasing, which will lead to a decrease in the reliability of the system as a whole.

The technical task to which this real utility model is directed is to eliminate all these drawbacks by transferring the functions of a central station or a data center to a compact and cheap alarm processing unit, which is constantly at the personal disposal of the owner of the protected facility.

The technical result is the maximum expansion of the effective area of the system to the boundaries of the selected wireless communication network (i.e., the application is not limited to only those regions where dispatch centers can be organized); elimination of expenses for the creation, operation and maintenance of a complex and expensive centralized infrastructure of the dispatch center, while maintaining all the positive aspects of security systems of this type, including the possibility of expanding the number of controlled objects; a significant increase in the efficiency of notification of a possible attack on the object of protection and / or the alarm processing unit using electronic warfare equipment due to the implemented possibility of periodically checking the state of the protection object using the alarm processing unit, which is constantly in the personal possession of the owner; improving the reliability and efficiency of notifying the owner of the event, due to the exclusion of the link "central station - the owner of the security facility".

An additional technical result of the invention is:

increasing the system’s functionality by providing the owner of the security facility with the opportunity to independently (without resorting to the help of the DC operator), using only the alarm processing unit, quickly modify the parameters and configuration of the security system, including: the composition and sensitivity of the security circuit sensors, methods and parameters alerts, caller lists

alerts, passwords, etc. Additionally, the owner can, by concluding an agreement with one or another central security point (PTO) and setting his phone number in the "ALARM LIST", protect his property by receiving additional services to combat theft / damage. At the same time, it is obvious that the monthly fee will be significantly lower than usual, since the main processing functions are carried out by the alarm processing unit, and not the central monitoring station.

Expanding the system coverage and reducing operating costs, due to the implemented opportunity to quickly change the operator and the mobile plan for the most profitable for the region (for example, when using the system in another territorial region), by simply replacing SIM cards.

The problem is solved, and the technical result is achieved due to the fact that the electronic security system and remote control of remote objects via wireless networks using existing radiotelephone networks, in particular GSM mobile networks, and a satellite radio-navigation positioning system such as GPS / GLONASS, contains two working together, devices: an alarm processing unit (BOST), which includes a microcontroller and an associated radio modem with an antenna, and an alarm analyzer (BAT) with communication with security sensors located on a stationary or mobile security facility and including a microcontroller and a radio modem connected to it with an antenna, the BAT being configured to cyclically check the status of the security facility with a set frequency and detect / signal an alarm situation, moreover, BOST made in the form of a personal block of the object of protection constantly at the disposal of the owner, which additionally includes a sound processing unit, an LCD indicator and a touch screen, and an additional BAT but it includes audio processing unit and a navigation receiver, such as GPS / GLONASS receiver, with the antenna unit Analyzer

alarm is configured to indicate “jamming” the communication channel by electronic warfare, the alarm processing unit is configured to conduct remote automatic monitoring of the protected object in the point-to-point mode through the alarm analyzer; BOST is configured to control the timely receipt of periodic calls from the BAT with additional confirmation of the safe state of the protected object during successful mutual identification of the alarm processing unit and the alarm analyzer unit during a session of exchanging coded service information packets in a voice channel using a DTMF-like hardware-software 8-bit code, with the ability to simultaneously transmit digital and voice information within predominantly non-tariffed operators rum of the radiotelephone network of time intervals and the construction of a selective connection according to a randomized algorithm, while in case of violations and / or blocking of the communication channel, for example, when the security system is affected by electronic warfare, the alarm processing unit is capable of triggering an alarming audio-visual-tactile notification of the owner later than after a time equal to the period of checking the status of the object of protection, and if the communication channel is in good condition, the alarm alarm analyzer is made with the possibility of emergency notification Subscribers about the following situations: triggering of the sensors of the security circuit, switching to autonomous power supply, critical discharge of the backup battery, exceeding the permissible temperature range, exceeding the boundaries set automatically or manually, in the form of voice and / or SMS messages to telephones from a predefined list (up to 8 mobile or landline numbers, including the number of the personal alarm processing unit).

Access to the protection, monitoring and control functions of the alarm analyzer block can be done through the voice menu (GM) when making a call from the phone (or from BOST) to the number of the alarm analyzer block,

moreover, the entrance to the specified menu requires an authorization password and can also be performed locally through audio communication between the BOST speaker or a telephone, for example, a mobile phone supporting DTMF tone dialing, and a BAT microphone, the output of which is connected to the corresponding input of the sound processing unit of the analyzer unit alarms, the aforementioned sound processing unit being configured to simultaneously (i.e., in one GSM communication session without redialing the number) use both the monitoring and control functions in the GM and phone functions, including the ability to hear the object of protection through the said BAT microphone and speak to the BAT speaker, the output of which is connected to the corresponding input of the said sound processing unit.

The system can be made expandable for monitoring several objects with an alarm analyzer block installed on each of them using one alarm processing unit, including periodically checking the status of each protected object and detecting and / or signaling the situation of possible “jamming” of the communication channel by means EW.

The alarm processing unit may be independently capable, i.e. performed by the owner himself, the operational modification of the parameters and configuration of the security system, in particular: the composition and sensitivity of the sensors of the security circuit, including the temporary parameters of the sensor signals, methods and parameters of the notification, including temporary parameters of the alarms (number, duration, delays, snoozes, etc. ), a list of subscribers, including individual filters for incoming messages, GSM notification parameters (number of repeated calls, delays, etc.), GPS / GLONASS receiver parameters, including intensive nce and methods of data updates.

The alarm processing unit may be configured to request (via SMS or voice channel) and display

location of the object of protection on the LCD indicator in the form of: marks on a vector electronic map, absolute coordinates (latitude and longitude), coordinates and names of 3 nearest objects (addresses) with distances to the object of protection.

The system can be configured to support a standard file system of non-volatile FLASH memory of the alarm processing unit and the alarm analyzer unit.

The system can be configured to save information about current events (arming / disarming, alarm situations, incoming / outgoing calls) with the date and time of the event, in the logbook as a log file in the FLASH memory of the alarm analyzer block, as well as information about the location, speed and direction of movement of the object of protection on the basis of the GPS / GLONASS receiver data recorded in the said log according to a predetermined algorithm with a specified frequency for subsequent transfer from the alarm analyzer block to the block ok alarm processing or a personal computer and viewing on the LCD indicator of the alarm processing unit or personal computer screen, in text form, or in the form of marks on a vector electronic map, with the ability to automatically and step by step forward and reverse scrolling points from recorded in a log file the route of the protected mobile, for example, vehicle, vehicle.

The system can be arranged to navigate directly inside the cabin while the mobile guarded vehicle is moving, while the alarm processing unit is configured to connect to the alarm analyzer unit and receive information from it from a GPS / GLONASS receiver, and the alarm processing unit displays it on the LCD indicator in the form of a mark on a vector electronic map together with information about the current coordinates, speed and direction of movement.

The alarm processing unit can be configured to notify other subscribers by phone from a predefined list (up to 8 mobile or landline numbers) using a special voice or SMS message in the absence of the reaction of the owner of the security object to the alarm to increase the reliability of the notification in case of possible loss / theft or inaccessibility to the owner of the alarm processing unit.

The alarm block analyzer can be configured to use backup batteries of various types and capacities by programmatically setting parameters stored in a file in non-volatile FLASH memory, in particular, maximum charge current and voltage, minimum charge completion current, and minimum allowable working voltage.

The alarm alarm analyzer may be capable of galvanically decoupling the power supply circuits, input circuits for connecting sensors and output circuits for connecting actuators to protect the electronic circuit from electrostatic charges, accidental or intentional exposure of inputs and / or outputs to electrical voltages exceeding the permissible limits values.

The alarm alarm analyzer can be implemented in an airtight industrial climate control case with IP65 protection level with the ability to maintain the temperature inside the case within specified limits by installing a thermostat in the case with a heating element and a temperature sensor to maintain the specified temperature in the cold season.

In the course of the study, it was revealed that the system can be made in the form of two devices working together: an alarm processing unit that performs all the functions of a central station dispatcher, which is constantly at the disposal of the owner of the security facility, and an alarm analyzer unit located independently on

stationary or mobile security facility, including a GSM modem with a SIM card, antenna and sound processing unit; GPS / GLONASS navigation receiver with antenna (when using the system to protect mobile objects); power supply with backup battery charge circuit; a microcontroller designed for general device control, including for processing signals from a GSM modem, GPS / GLONASS receiver and security sensors; transmitting encoded information about the state of the object of protection according to a predetermined algorithm with a configurable frequency or urgently in case of an alarm situation via mobile networks to the alarm processing unit, which includes a radio modem, in particular a GSM modem, with a SIM card, antenna and unit sound processing; LCD indicator for displaying cartographic and semantic information, a touch screen for data entry and control of the alarm processing unit; power supply with a standard battery charge circuit; microcontroller designed for receiving and processing alarm messages, performing sound and other notification to the owner, preparing data for display on the LCD, processing data entered from the touch screen and other security functions, including monitoring the object of protection and controlling executive devices connected to the unit - an alarm analyzer, while the alarm analyzer block is capable of remotely automatically checking the status of the object of protection with a periodic set depending on the degree of risk alarm and alarm detection / signaling by exchanging service coded information packets between the alarm analyzer block and the alarm processing block by the DTMF-hardware-like method in a predominantly non-tariffed mobile communication operator time interval, as well as with the possibility of transmitting an alarm notification about the following situations: triggering of the sensors of the guard circuit, switching to autonomous power supply, critical discharge

backup battery, going beyond the permissible temperature range, going beyond automatically or manually set boundaries, through a wireless network in the form of voice and / or SMS messages to telephones from a predefined alert list (up to 8 mobile or stationary numbers, including the alarm processing unit number )

The system is capable of supporting the standard file system of non-volatile FLASH memory of the alarm processing unit and the alarm analyzer unit, which provides flexibility and simplicity of reprogramming the system at the file transfer level with settings, data and updates via the following communication channels: personal computer - signal processing unit alarm via USB interface, alarm processing unit - alarm analyzer using standard serial UART interface. The capacities of the FLASH-memory of the BOST and BAT programs are 128 and 32 MB, respectively, and can be expanded up to 1 GB.

The system is expandable and allows you to control several objects, including periodically checking the status of each object and detecting / signaling the situation of possible “jamming” of the communication channel by electronic warfare equipment. The number of monitored objects while maintaining protection efficiency does not exceed 10. This value is indicated taking into account the reduction in the operating life of a standard battery and subject to a 10-minute reaction to blocking the communication channel. Without using the cyclic state check procedure, the system allows monitoring up to 500 objects.

The essence of the utility model is illustrated by the following drawings, revealing implementation details:

Figure 1 is a functional diagram of a block analyzer alarm.

Figure 2 is a functional block diagram of the alarm processing unit. As shown in figure 1, the alarm analyzer is made in the form of an electronic circuit in a thermostatic sealed enclosure 1 with a level

IP65 protection, and contains a microcontroller (MK) 8, with a radio modem (GSM modem) 3 connected to it with a remote GSM antenna 2, a SIM card 4 and an audio information processing unit 5 with an external speaker 6 and a microphone 7; GPS / GLONASS receiver module 9 with a remote antenna 10; FLASH-memory 11; blocks of galvanic isolation of input 13 and output 14 signals, with security sensors 12 connected to them, respectively, and relay block 15 with actuators 16; power supply 17. Actuators 16 (sound and light alarms, blocking circuits, etc.) and sensors of the security circuit 12 are located outside the thermostatically controlled building at the guarded object. The power supply 17 is controlled by MK 8 and generates all the voltage schemes necessary for power supply, and also provides a charge for the backup battery 20.

MK 8 ensures the operation of the entire device as a whole, by:

management and exchange of information with a radio modem (GSM modem) 3 and a module of GPS / GLONASS receiver 9; receiving and processing signals of the sensors 12 through the galvanic isolation unit 13 and issuing through the galvanic isolation unit 14 and the relay unit 15 control signals to the actuators 16; measuring the voltage and charge current of the backup battery 20, respectively, through the inputs 7 and 8 of the built-in ADC associated with the corresponding outputs 3 and 4 of the backup battery charge circuit (SZRA) 25, providing control of the charging process using output 9 of the built-in DAC connected to input 5 SZRA 25; maintaining the temperature inside the case within specified limits, measuring the temperature with a temperature sensor 22 mounted on the radiator cover 21 of the battery 20 and controlling, through a galvanically isolated output 3 of the galvanic isolation unit 14, connected to it by the input 3 of the transistor CMOS key 23, turning on / off in the load circuit, the resistor-heater 24, having thermal contact with the casing-radiator

21, thereby providing the required temperature condition of the backup battery 20.

MK 8 contains an internal non-volatile FLASH-memory of programs with a capacity of up to 1.0 MB for storing executable program code and a data memory of up to 32 Kb. The internal FLASH-memory of the programs has two-level hardware protection to prevent unauthorized reading / copying of contents. External FLASH-memory 11 with a capacity of 32 MB is used to store data files, sound WAV-files of voice messages and other service information.

GSM-modem 3 is made in the form of a modular cellular modem Wismo or similar. Reception / transmission of data and commands between MK 8 and GSM-modem 3 is carried out on a serial bus connecting input / output 1 of MK 8 and input / output 2 of GSM-modem 3.

The navigation receiver of the GPS / GLONASS 9 satellite radio navigation system is made in the form of a module based on the SiRFstar chipset or similar.

Blocks 13 and 14 of galvanic isolation are made optically isolated to prevent the system from malfunctioning in the event of accidental or deliberate exposure to inputs and / or outputs with electric voltage exceeding the permissible limit values, including static electricity charges. As sensors of the security circuit 12, which perform the functions of signaling devices to penetrate the object of protection, any standard sensors with an output of the “open collector” type can be used, depending on the type of protected object: impact, volume, position, tilt, etc., as well as contact , magnetic, etc. .. The sound processing unit (BZO) 5 is used for receiving, converting, matching and transmitting analog signals in the GSM audio path between the MK 8 and the GSM modem 3. The BZO 5 has several operating modes set by the MK 8 using control

logical signals at the outputs 16 and 17, connected, respectively, with the inputs 11 and 12 of the BZO 5.

In the telephone mode (at the inputs 11 and 12, the inactive state), the BZO 5 receives the input 10 from the external microphone 7, the voice converted into an electric signal, and transmits it from output 8 to the first microphone input 6 of the GSM modem 3 connected to it. At the same time, the BZO 5 from the first speaker output 5 of the GSM modem 3 receives a voice signal from the GSM channel to its own input 5 and transmits it to output 9 remote speaker 6.

In the mode of receiving / transmitting data (input 11 active state, input 12 inactive state) MK 8 through the outputs of the built-in DAC 11 and 13 connected, respectively, to the inputs 7 and 3 of the BZO 5, outputs software-generated audio signals DTMF-like 8 -bit code to the first summing amplifier built into the BZO 5 (not shown in the diagram), which, in turn, transmits the total encoded signal to the GSM channel through the 4 BZO 5 output 4 to the second microphone input 4 of the GSM modem 3. At the same time, from the voice channel of the GSM channel from the second speaker output 3 of the GSM modem 3, the BZO 5 receives input 1 of the encoded response signal from the alarm processing unit and passes it through output 2 to input 14 of the built-in ADC of microcontroller 8, which, in turn, software decodes this signal.

In the voice recording / playback mode (input 11 is inactive, input 12 is active) MK 8, through the output of the built-in DAC 11 connected to input 7 of the BZO 5, plays voice messages recorded as WAV files in the external FLASH memory 11 to the second amplifier built into the BZO 5 (not shown in the diagram), which, in turn, transmits these messages through the 8 BZO 5 output to the GSM channel through the first microphone input 6 of the GSM modem 3. At the same time, from the voice channel of the GSM channel from the first speaker output 5 of the GSM modem 3 BZO 5 receives input 5 audio with ignal from the alarm processing unit and

through output 6 it passes it to input 12 of the built-in ADC MK 8, which, in turn, can record this signal as a WAV file in an external FLASH memory 11 for subsequent playback.

It is important that the transition from one BZO 5 operating mode to any other does not require breaking the current GSM voice connection, which increases the system’s efficiency, allowing in one communication session (without redialing) to perform both monitoring functions and voice telephone functions, including recording / playback of audio information.

The power supply unit 17 structurally contains a power converter with galvanic isolation 18, to the input 1 of which a constant voltage V ₁ is supplied from the on-board network, or, in case of use at stationary objects, from the public utility network through an adapter. From the output 2 of the power converter 18, the stabilized voltage V _{2 is} simultaneously supplied to the input 1 of the LDO power converter 19 and to the input 1 of the SERA 25. The LDO power converter 19 generates voltages at the outputs 2 and 3: respectively, V ₄ for the power supply of the GPS / GLONASS module receiver 9, and V ₅ for the rest of the digital circuit. SZRA 25 operates under control of MK 8 and provides a battery 20 charge in the modes of stabilization of current and voltage. The hardware of SZRA 25 is made with the possibility of using batteries of various types and different capacities due to the flexible and universal software setting of a number of parameters stored as a file in the FLASH memory 11: maximum current and charge voltage, minimum charge completion current, minimum permissible operating voltage, and etc. SZRA 25 switches to current stabilization mode under the action of a control signal of a high logic level at input 6 connected to output 10 of MK 8. The control signal mentioned turns on by the internal CMOS transistor (not shown in the diagram) an additional feedback loop in the circuit of the automatic current regulator, which supports the charge current proportional to the control current at the output of 2 SRA 25

voltage at input 5, which is set from output 9 of the DAC MK 8. In voltage stabilization mode, SZRA 25 is switched by a signal of reverse polarity of a low logic level at input 6 from output 10 of MK 8, which disconnects the additional feedback loop mentioned and the control voltage at input 5 connected to the output 9 of the DAC of the microcontroller 8, sets the maximum (variable for each type of battery) value of the charge voltage for the internal circuit of the automatic voltage regulator with an integrated current limiter and greater than some threshold value determined by the nominal capacity of the battery.

The alarm processing unit is made in the form of a compact portable device measuring 95 × 49.5 × 19 mm and weighing 86 g. As shown in figure 2, the BOST contains a microcontroller 33, with a GSM modem 28 connected to it with an antenna 27, SIM a card 29 and a sound information processing unit 30 with a built-in speaker 31 and a microphone 32; LCD indicator 35; a touch panel control unit 36, with a touch panel 34 connected thereto; RAM 37; FLASH-memory 38; USB controller 39; power supply 40. The power supply 40 is controlled by MK 33 and generates all the voltage schemes necessary for power supply, and also provides a charge for the battery 17.

MK 33 ensures the operation of the entire device as a whole, by: managing and exchanging information with a GSM modem 28; receiving information from the touch panel 34, outputting information to the LCD indicator 35; monitoring the voltage and current of the battery 42, respectively, through the inputs 6 and 7 of the built-in ADC associated with the corresponding outputs 3 and 4 of the power converter 41, providing control of the charging process using the output 9 of the built-in DAC.

MK 33 contains an internal non-volatile FLASH-memory of programs with a capacity of up to 1.0 MB for storing executable program code and data memory up to 32 Kb. The internal flash memory of programs has

two-level hardware protection to prevent unauthorized reading / copying of content.

External FLASH-memory 38 with a capacity of up to 1 GB is used to store data files and other service information.

External random access memory 37 with a capacity of up to 1 MB is used to store data and intermediate calculation results.

GSM modem 28 is made in the form of a modular cellular modem Wismo or similar.

SIM card 29 is installed in the holder, allowing you to quickly replace the card.

USB controller 39 is used to exchange information with external control devices having a USB-HOST interface, for example with a personal computer. Information is exchanged by transferring control of the external FLASH memory 38 to the USB controller 39 using an active logic level signal at input 3 connected to output 6 of MK 33. At the same time, MK 33 transfers its input / output 19 to a high impedance state, thereby disconnecting it from the general the bus connecting the MK 33 with the input / output of the FLASH memory 38 and the input / output 1 of the USB controller 39. Thus The USB controller 39 receives a common bus at its disposal and becomes the interface between the USB-HOST controller of the PC 43 connected to the input / output of the USB bus 2 of the USB controller 39 and the external FLASH memory 38, supporting all operations of the standard FAT 16 file system. MK 33 regains control of the FLASH memory 38 with an inactive logic level signal at output 6 connected to input 3 of the USB controller 39, disconnecting the latter from the common bus.

The control panel of the touch panel 36 allows you to alternately connect the internal (not shown) two-coordinate resistive dividers of a 4-wire analog touch panel 34 under

by controlling the logic level signals at inputs 3 and 4 connected to outputs 4 and 5 of MK 33, respectively, convert the resistance of the mentioned dividers into a pair of voltage values proportional to X (input 3 in the active state, input 4 in the inactive state) and Y (input 3 in the inactive state, input 4 in the active state) to the coordinates of the pressed point, and transmit these voltages to outputs 1 and 2, connected, respectively, to inputs 2 and 3 of the built-in ADC MK 33.

The sound processing unit 30 is used for receiving, converting, matching and transmitting analog signals in the GSM audio path between the MK 33 and the GSM modem 28. The BZO 30 has several operating modes specified by the MK 33 using control logic signals at the outputs 16 and 17 connected , respectively, with inputs 11 and 12 of the BZO 30.

In the telephone mode (inputs 11 and 12 are inactive), the BZO 30 receives the input 10 from the built-in microphone 32, the voice converted into an electric signal, and transmits it from output 8 to the first microphone input 6 of the GSM modem 28 connected to it. At the same time, BZO 30 from the first speaker output 5 of the GSM modem 28 receives a voice signal from the GSM channel to its own input 5 and from output 9 transfers it to the built-in speaker 31 (directly or through the built-in amplifier).

In the mode of receiving / transmitting data (input 11 active state, input 12 inactive state) MK 33 through the outputs of the built-in DAC 11 and 13 connected, respectively, to the inputs 7 and 3 of the BZO 30, outputs software-generated audio signals DTMF-like 8 -bit code to the first summing amplifier built into the BZO 30 (not shown in the diagram), which, in turn, transmits the total coded signal to the GSM channel through the 4 BZO 30 output to the second microphone input 4 of the GSM modem 28. At the same time, from the voice channel of the GSM channel from the second speaker output 3 of the GSM modem 28, the BZO 30 receives input 1 of the encoded response signal from the alarm analyzer unit and transmits via output 2

it to the input 14 of the built-in ADC MK 33, which, in turn, programmatically decodes this signal.

In the voice recording / playback mode (input 11 is inactive, input 12 is active) MK 33, through the output of the built-in DAC 11 connected to input 7 of the BZO 30, plays voice messages recorded in the form of WAV files in the external FLASH memory 38 to the second amplifier built into the BZO 30 (not shown in the diagram), which, in turn, transmits these messages through the output 8 of the BZO 30 to the GSM channel through the first microphone input 6 of the GSM modem 28. At the same time, from the voice path of the GSM channel from the first speaker output 5 of the GSM modem 28 BZO 30 receives at input 5 aud The signal from the alarm analyzer block and through output 6 transfers it to the input 12 of the built-in ADC MK 33, which, in turn, can record this signal as a WAV file in an external FLASH memory 38 for subsequent playback.

The transition from one operating mode of the BZO 30 to any other does not require breaking the current voice GSM connection, allowing in one communication session (without redialing) to perform both monitoring functions and voice telephone functions, including recording / playback of audio information.

The power supply unit 40 structurally comprises a power converter from the battery circuit (PPSZB) 41 having an input 2 to which voltage is always applied V ₈ from the battery 42 and the input 1 to which are periodically for the battery recharge 42 is supplied a constant voltage V ₆ from the adapter (not shown in the diagram), which converts either an alternating voltage of a public utility network or a constant voltage of an on-board network. An internal LDO converter (not shown in the diagram) converts the larger of these two input voltages V ₆ or V ₈ into a stabilized voltage V ₇ at output 7, which is necessary for the operation of the entire BOST electronic circuit. In addition, the voltage of the battery V ₈ also directly feeds the GSM modem 28. In charge mode

battery 42, PPSZB 41 under the control of MK 33 provides a charge in the modes of stabilization of current and voltage. Parameters: the maximum current and charge voltage, the minimum charge completion current, the minimum allowable working voltage, etc. are stored as a file in the FLASH memory 38. PPSZB 41 switches to current stabilization mode under the action of a high logic level control signal at input 6 connected with an output of 10 MK 33. Said control signal includes, with the help of an internal CMOS transistor (not shown in the diagram) an additional feedback loop in the circuit of an automatic current regulator that supports charge current at output 2, proportional to the control voltage at input 5, which is set from the output 9 of the DAC MK 33. In the voltage stabilization mode PPSB 41 is switched by a signal of reverse polarity of a low logic level at input 6 from output 10 of the MK 33, which disconnects the mentioned additional feedback loop, and the control voltage at the input 5, connected to the output 9 of the DAC of the microcontroller 33, sets the maximum value of the charge voltage for the internal circuit of an automatic voltage stabilizer with a charge current limiter exceeding that determined by it bone battery threshold value.

Thus, in the described system, over the radio channel, including that supported by the GSM 900/1800 communication standard, packets of coded service information are exchanged automatically between the alarm analyzer unit and the alarm processing unit, at a specified frequency, which allows remote monitoring of the security object. When an unauthorized access is attempted, the detection sensors installed on the guarded object transmit alarms to the alarm analyzer unit, which generates, encodes and sends voice and / or SMS messages to the alarm processing unit, as well as in accordance with the specified algorithm mailing list to subscribers on the alert list.

If a powerful broadband interference source is possibly turned on in the zone of the alarm analyzer block or the alarm processing block, the communication channel will block. In this case, the system will perceive the lack of response of one of the blocks during the next session of exchanging encoded radio packets as the influence of electronic warfare equipment, which will also lead to an alarm, in particular, if there is no response from the alarm processing unit, the alarm analyzer will notify other subscribers from the list. And if there is no response from the alarm analyzer, the alarm processing unit, no later than after a period equal to the period of checking the status of the object of protection, will notify the owner of the danger, and if there is no reaction of the owner to the alarm, he will also notify the subscribers from the list.

The utility model has a wide scope and can be used in systems for various purposes, such as fire, security, etc., with the ability to remotely control actuators connected to the alarm analyzer block.
