Moreover, a common power bus and one or more voice annunciators are introduced, each of which contains serially connected voice power supply and control units, a voice message shaper and a loudspeaker, and sound and light power and control units are respectively introduced into each sound siren and each light siren , the outputs of which are connected respectively to the siren and to the indicator light, the inputs of all power supply and control units are connected to a common power bus, which is connected on AUC to the input power control apparatus, wherein the control device is adapted to generate and transmit power on the shared bus frequency-modulated high-frequency signals carrying audio control command and voice light sirens. The disadvantage of this device is: a limited number of controlled security zones in the control panel, low system reliability and cryptographic protection of the system and data transmission channels, the inability to use alternative data transmission channels, such as digital Ethernet (TCP / IP) / GPRS channels, channels of cellular communication operators (GSM -channel), which generally reduces the likelihood of message delivery in a given period of time and leads to low efficiency of decision-making in the monitoring center. Thus, the aim of the claimed invention is to overcome the above problems.

According to the invention, there is provided a system for receiving, transmitting, monitoring and processing data, comprising a receiving and monitoring device, which includes a wireless zone expansion subsystem with at least one wireless zone expansion module and at least one wireless glass and / or glass break detector, and / or door and / or window magnet contacts and / or fire detection sensor - detector and / or remote control remote control, wireless zone expansion module provides two-way radio communication with at least one wireless sensor and / or remote control remote control, while it is connected via an internal communication bus of the RS-485 interface to a control device, and the wireless zone expansion module is configured to continuously monitor the radio channel with the said sensors, the sensors being made with the possibility of generating a data packet of the control and diagnostic message, consisting of a pseudo-random byte of encryption, a unique sensor number, and the serial number of the transmitted of the data packet, the message itself, the signal level of the received previous response from the corresponding wireless zone expansion module and the noise level in the sensor zone and are equipped with a transceiver that transmits a signal in the frequency range 868.0 ... 868.2 MHz with an output power of up to 10 mW short-term up to 5- ten ms pulse encoded bursts of a frequency-manipulated signal with a narrow emission spectrum for transmission to the corresponding module for expanding wireless zones.

The transceiver of each wireless expansion module, which is in receive mode, receives the data packet transmitted by the corresponding wireless sensor, monitors it using a cyclic redundancy code (CRC) and, if the CRC matches, decrypts it in accordance with the received encryption byte, compares the serial numbers of the data packets received from the sensor and expected (next from the previous one) and if the above conditions coincide, it generates an identical response data packet. The transceiver of the wireless extension module transmits a response data packet in a specific time window that corresponds to a specific time window of the wireless transceiver transceiver. If at least one of the above conditions for checking the data packet is not fulfilled, the response data packet is repeated with another pseudo-random encryption byte, while repeated data packets are sent by triples with floating time intervals inside triples and increasing intervals between triples.

DETAILED DESCRIPTION OF THE INVENTION

Reception and control devices in the fire alarm system are an intermediate link between the primary means of detecting intruders (various sensors for detecting the presence of, for example, wireless motion sensors, glass breakers, door or window contact sensors or fire detection sensors (detectors)) and notification system. PPC can be used in stand-alone operation at a guarded facility with the connection of sound and light warning systems and perform the following main functions: receiving and processing signals from detectors; management of sound and light annunciators; power supply of detectors via an alarm loop (AL) or on a separate line; AL status monitoring; ensuring procedures for taking under guard and disarming the facility with the possibility of their transfer to the centralized surveillance system (SCS). STS - a set of software and hardware tools or an integral part of a notification transmission system installed in a centralized security center for reception from security terminal devices, for example, from a control panel or a relay of security system message alerts: penetration of guarded objects and / or fire, service and diagnostic notifications, processing, display, registration of the received information and presenting it in a given form for further processing. The monitoring center has an appropriate transceiver device, for example, a GSM modem, which processes the received messages from the PAC and provides them to the operator in the form of convenient information for visual perception to monitor the behavior of attackers at a controlled object or the development of other negative situations, which allows to make a decision and optimize the actions of operational response groups . So the operator analyzes the information, evaluates the negative situations at the facility and the actions that need to be taken, for example, turning on the siren, the operator determines the identifiers of the executive programs with which he can influence the system. The operator sends a call corresponding to the identification number of the protected object and its control panel or sensor and the number of the executive program that the system must execute in the programmable module for the corresponding executive module (sensor, detector, etc.).

The control panel can form, for example, 4 wire zones for working with detectors, for example with detectors with loop control, built using current separation technology and with two-wire detectors with loop power, as well as 8 wireless zones for working with various wireless sensors. The control panel contains at least one built-in wireless zone expansion module - a radio transmitter, which ensures its operation with wireless detectors - sensors, from which messages are sent to the control panel: control, alarm, recovery, opening the case, battery discharge, test. Information about the events that may occur can be transmitted from the control panel to the monitoring center via a telephone line and / or a radio channel, for example, via external telephone channels or a radio communicator - a GSM modem designed to send messages in the form of SMS, Datacall, DTMF parcels and in the form of voice messages via GSM cellular communication channel or GPRS. The control panel contains: a control control panel (control buttons, an LCD display panel and an audible signaling device) and at least one extension module for wireless zones that are connected to each other via the RS-485 interface. The RS-485 protocol is the most widely used industry standard using a bi-directional balanced transmission line. The protocol supports half-duplex communication and multipoint connections, ensuring the creation of networks with up to 32 nodes and transmission at a distance of up to 1200 m. At the same time, one twisted pair of conductors is enough to transmit and receive data. Alternatively, the RS-232 interface can also be used as the interface and communication buses between the gearbox modules.

The system can be programmed and use several security and zone control modes: “round-the-clock zone monitoring” regardless of the security mode, “full security mode”, “delay mode”, when the operation of the detectors included in the corresponding zone is ignored during the delay time for exit, which allows you to leave the protected room, and when disarming, the operation of the activated detectors is ignored during the entry delay time, which allows you to enter the protected room and perform the removal procedure ma protection.

As primary means of detection, various sensors are used. Such as wireless / wired motion and / or glass break sensors, and / or door and / or window magnetic contacts and / or remote controls or panic buttons. The motion sensor is a passive infrared thermal vibration sensor. The sensor can have a wide viewing angle and can control the whole room, the room, if it is installed in the corner of the room, or it can be a directional motion sensor, which allows you to protect the selected area or object in the room. The door and / or window magnetic contact sensor for opening a door / window (reed switch) is placed on the window or door frame and is triggered if parts of the sensor are separated by a certain distance, usually 1-3 cm. In addition, a gas leak sensor can be used as an independent gas leak detector and / or fire detectors that may have a built-in siren. To save battery energy, the sensor provides a mode for turning off the LED display, which is the normal operating mode of the sensor. It is possible to connect several panic buttons in the system, while pressing the panic button triggers an alarm regardless of the mode of operation of the system. It is also possible to connect a wireless siren, which is an audio output device installed at the security facility.

The remote control (RC) is used to interconnect with the control panel and to provide the possibility of remote control by it, in particular, arming / disarming the system, to turn on / off the emergency / fire alarm, to perform the functions of turning on / off the lighting devices. The operation of the remote control subsystem extension wireless zones uses additional encoding of the transmitted commands. In addition to the principles of message transmission below, data packets from the remote control are encrypted according to GOST 28147-89, and each time the packet numbers are synchronized between the remote control and the wireless zone extension module. Thus, additional protection against hacking messages. The console may consist of interconnected microprocessor data processing, radio frequency or infrared transceiver that sends encoded commands. Also, the remote control may additionally contain a backlit LCD and / or separate LED indicators: "Fire", "Fault" and others. The user enters commands by means of buttons for entering, for example, a command for changing the security modes (arm, disarm, alarm).

The control panel contains a control device associated with the corresponding wire zones (security alarm loops), with a control panel and at least one wireless zone extension module and a notification transmission module connected to one of the outputs of the control device, which is configured to transmit notifications to the monitoring center via wired and / or wireless communication channels, by means of a transceiver device connected to it, which provides two-way communication with a transceiver device, Becoming in a CCN. As a transceiver, for example, a GSM modem with a block for storing telephone numbers of the monitoring center, or via the Ethernet interface, via GPRS communication channels can be used.

The control device comprises a processor, a memory unit associated with the processor. The outputs of the detectors are connected to the corresponding inputs and outputs of the hardware-software tool (processor) using the connecting wires or security alarm loops, and the wireless sensors are connected via a radio channel to the wireless expansion modules - transceivers, which are also connected to the corresponding input-outputs by their inputs and outputs the processor. The first input-output of the processor is connected to the input-output of the programmable module, and the second input-output of the processor is connected to the executive modules, which must be triggered by the commands of the system. The third input-output of the processor is connected to the inputs of the sirens of light and / or sound alarm. The control panel also contains a power circuit from a stabilized power source connected in series, configured to connect to the mains or battery, a power bus to which the power inputs of the control device, the control panel, at least one wireless zone expansion module and a transceiver (GSM) are connected modem).

The operation of wireless sensors in the expansion subsystem of wireless zones is based on the use of: an unlicensed frequency range of 868.0 ... 868.2 MHz allocated for the operation of security equipment devices with an output power of up to 10 mW, which allows users to freely use them for their intended purpose; short pulse encoded transmissions of a frequency-manipulated Gaussian signal in the range of 868 MHz, which made it possible to transmit short (up to 5 ms) transmissions with a narrow radiation spectrum. Two-way messaging with the wireless zone expansion module is also used, which ensures guaranteed message delivery and reduces the number of transmitted messages, while each wireless sensor has its own unique number automatically set and registered during production, which eliminates the possibility of its substitution or personnel errors. In addition, multilevel packet integrity monitoring is ensured, which eliminates the possibility of false alarms, and constant monitoring of radio communications with sensors due to short test intervals of 2 minutes, which makes it possible to determine the absence of radio communications after 3 minutes. The system of wireless sensors, the wireless zone expansion module and the control panel allows you to monitor and display the status of the battery and the radio communication with each sensor.

Connecting the wireless zone expansion subsystem together with the wireless sensors to the control panel allows you to: increase the number of controlled zones in the control panel from 4 to 12 (8 wireless zones), connect up to 4 wireless sensors to the control panel for each wireless zone, and connect up to two expansion modules to the control panel wireless zones and place them in various places to ensure reliable radio communication with the installed sensors, to reserve the communication channels of the sensors with the control panel, because in case of loss of communication with one of the expansion modules of the wireless zones, the second will communicate with the sensors whose signals it receives, while duplication of alarm events does not occur.

Messages are transmitted from the sensors to the wireless zone expansion module in accordance with the following principles and in the sequence: if it is necessary to send a message to the central, the sensor generates a data packet of the control and diagnostic message, consisting of a pseudo-random encryption byte, a unique sensor number, and the serial number of the transmitted packet, the message itself, the signal level of the received previous response from the wireless expansion module and the noise level in the sensor area; the packet thus formed is transmitted by the transceiver of the sensor to the air; The transceiver module of the wireless expansion module, which is in receive mode, receives this packet, if CRC16 (cyclic redundancy code) matches, decrypts it in accordance with the received encryption byte, compares the sequence numbers of packets received from the sensor and the expected (next from the previous) and if it matches the above conditions forms a response packet of an identical structure; in a certain time window, the transceiver of the wireless zone extension module transmits the generated packet to the air; at the same specific time window, the transceiver of the sensor turns on its receiver and receives a response packet, decrypts it in accordance with similar criteria, and if the exchange procedure is correct, the sensor switches to standby mode; if at least one of the above requirements is not met, the message is repeated, but with a different pseudo-random encryption byte, and possibly other signal and noise levels (i.e., the message retry packet is not similar to the previous packet); repeated packets are sent by triples with floating time intervals inside triples and increasing intervals between triples, which allows to get rid of packet overlays from different sensors and to avoid excessive energy consumption of the sensor battery for message retries; if the packet numbers of the sensor and the extension module of wireless zones do not match, they are synchronized according to the specified algorithm; If the test period of packet transmission has expired and there were no events during this period, a test packet for monitoring communication with the sensor is formed, which fully corresponds to the message structure, while priority is given to alarm messages during packet transmission.

The data of the control and diagnostic message received by the wireless zone expansion module from the sensors are transmitted to the central via the RS-485 bus. Several different modules operating in the central polling mode can be connected to this bus. Two wireless expansion modules can be connected to the control panel. Wireless zone expansion modules form and transmit to the radio channels only packets assigned to sensors (registered in the system). They are attributed to wireless sensors located in the area of their radio visibility. However, if one of the expansion modules of the wireless zones fails, does not respond to the polling of the control panel or does not receive packets from the assigned sensors, and the other expansion module of the wireless zones receives these packets, the control panel transfers control of these sensors to this module and generates a malfunction event of the specified wireless zone expansion module, which provides system redundancy and increases its reliability.

In order to exclude the possibility of registration (operation) of sensors with expansion modules for wireless zones of other control panels, a unique time-limited procedure for registering sensors has been implemented. It consists in the fact that the central unit enters the wireless zone extension module into the sensor registration mode for a period of not more than 2 minutes. If registration of the sensor has occurred, the wireless zone expansion module will exit registration mode, displaying on the LCD the type of registered sensor, its original serial number, radio signal level and sensor batteries. The sensors transmit the registration packets of the control and diagnostic messages only within 30 seconds after turning on the power to the sensor, if during this time the sensor has not received registration confirmation, it lights up the red LED for 1 second and goes into sleep mode, from which it can only be deduced reset and re-energize. When accepting the registration package, the sensor indicates successful registration with the status of the radio and battery.

The control panel supports the following set of reverse commands for control and diagnostic messages: "Status Poll", "Arming Confirmation", "CCC Verification Confirmation", "Remote Capture (re-logging)", "Arming Lock", "Arming Unlock", "Encryption Key Change" , "Sending a text notification to the owner with the display on the LCD", "Downloading new settings to the control panel", "Updating the control panel settings." Obtaining firmware and updating the software in the programmable module of the control panel is performed automatically either after receiving or entering the “Apply firmware” command or in the automatic update check mode. Inverse commands of the device can be received on various communication channels: GSM, GPRS, Ethernet.

Next, the response information package-command is generated at the monitoring center, which is sent to the control panel. After receiving a command from the monitoring center, the control panel checks it for validity and permits its operation (table 3), then it performs and completes the check of the CTS. The control panel indicates the progress of the CTS check, indicating the success of the result, or the verification step that failed. Thus, the operability of the detector (or panic button), the integrity of the wire loop, installation, communication channel of the control panel with the monitoring center and the central control panel with the control panel are checked.

After receiving a command from the monitoring center, the control panel checks it for validity and permission of its work (table 4), then it executes - puts the group under protection and generates and sends to the monitoring center a report on the delivered (or interconnected) groups via one of the programmed communication channels. If this group was guarded and there were unaltered alarms in it, they are canceled, but the report on them remains available to the user when viewing from the LCD.

After receiving a command from the monitoring station, the control panel checks it for validity and permission of its operation (table 9), then executes - receives data from the monitoring center and writes it to an alternative memory area (for GSM DataCall everything is done in one communication session). After loading the data into an alternative memory area and checking their integrity, the control panel sends to the monitoring station a report on the readiness for reprogramming through one of the programmed communication channels.

Updating the control panel settings.

After loading the settings and sending a report on the readiness for reprogramming, the control panel expects the command to rewrite the new configuration from the alternative memory area to the main one.

The generated packet is sent to the control panel. After receiving a command from the monitoring center, the control panel checks its validity and permission of its operation (table 11), then performs the following: sends a report on the beginning of the firmware download, connects to the FTP server, downloads the firmware, checks its integrity, sends a report to the end of the download SCN on readiness to replace the firmware and its serial number. If the auto-update firmware option is set, then after a predetermined time (about a minute) after sending a report about the readiness for updating, the control panel restarts and installs a new firmware. If this parameter is not set, the control panel waits for the "Apply firmware" command from the monitoring center. If the automatic check for firmware update availability is set and its frequency is set (in minutes), the control panel will automatically download the new firmware, send a report on the readiness for updating to the monitoring center and wait for the “Apply firmware” command from the monitoring center to install the new firmware.
