The disadvantage of the known solution is the ability to work only with "own" sensors. Lack of a single structure for placing equipment of various subsystems, lack of a single power supply system. The last two points, in fact, are left to the mercy of the designers, who themselves must choose the solution to the problem.

This technical solution was adopted as the closest analogue.

The technical problem solved by using the developed server is to develop an assortment of security systems.

The technical result achieved by the implementation of the developed technical solution consists in increasing the efficiency of security.

To achieve the specified technical result, it is proposed to use the server of the local section of the perimeter of the integrated security complex of the developed design. It contains a case in which a 48 - 56V power supply is installed, a 24V power supply, a backbone switch containing, among other things, an optical port, a signal processing unit with an installed communication module and a power supply module, an input voltage protection module connected to the power supply network , while the server case is made in the form of two nested cabinets, the inner one is thermostatted, in the lower part of the thermostatted case there is a basket with a backplane for installing controller boards that receive information from peripheral devices of security and fire and alarm alarms, CCTV and access control and performing the functions of switching and protecting circuits, backplanes are installed in the lower part of the outer case for connecting peripheral equipment, while all backplanes are factory-wired with controller cards installed in the basket of the inner case; power supplies, signal processing unit, input voltage protection module, temperature controller unit, a network protection module is installed at the power supply input to the server, the power supply input is connected through the network protection module to 48 - 56V and 24V power supplies, the 24V power supply output is connected to the backplane the lower cage board and backplanes for connecting equipment requiring 24V power supply, the output of the 48-56V power supply is connected to the backbone switch and backplanes for connecting equipment requiring 48-56V power, the outputs of the controllers are connected to the inputs of the signal processing unit to the inputs of which are connected peripheral devices for fire and security alarms, CCTV and access control, while the inputs of the trunk switch are made with the ability to connect the output of the signal processing unit, outputs of the video recorder boards, and the optical port of the trunk switch is connected to an automated workstation (AWS) or and to the optical port of another server, while acting as a signal repeater.

It can also additionally contain a loop and voice communication control module, a loop and access control module, a hub module, a notification signal switching module, a power module, a load control board, a video server for connecting analog AHD video cameras, an AHD video receiver module, a PoE switch for connecting IP cameras, SIP VOIP gateway 4-channel.

The server of the developed design performs the functions of collecting, processing and broadcasting signals coming from sensors of security and fire and alarm alarms, security television, organizing voice communication and alerting to local perimeter sections, preferably, but not exclusively, areas of airports, railway stations.

The server is designed for operation in the temperature range from minus 50 ° C to 50 ° C, in conditions of precipitation and dust. This is ensured by the special design of the case, which consists of two nested cabinets, like "nesting dolls".

The internal thermostated case houses the electronic equipment, the external sealed case serves to protect the equipment from adverse environmental factors (precipitation, dust) and as a radiator-heat exchanger. In the lower part of the outer case, there are boards for connecting power circuits and communication lines.

The temperature regime in the inner case is maintained as follows. When the upper temperature threshold is reached, the cooling device is automatically turned on - the supply and exhaust fans, which provide cooling of the inner case due to air circulation in the space between the outer and inner cases and its heat exchange with the external environment. When the lower temperature threshold (0 ° C) is reached, the heating device is automatically turned on. The server is protected from direct sunlight by an additional metal shield.

The server is designed to collect, transform and transmit information to a centralized observation point.

The server together with the centralized observation point provides the following functions:

- security alarm;

- alarm signaling;

- fire alarm;

- access control and management;

- security television;

- duplex voice communication;

- notification (individual, group, general);

- control of executive devices.

Information from the peripheral equipment goes to the server backplanes, which perform the functions of switching and circuit protection. From the cross-section, all information goes to the processing and digitization modules (signal processing unit, video server, VOIP gateway), where it is processed by the corresponding modules, converted into the Ethernet protocol and transmitted to the Ethernet switch.

From the Ethernet switch, information via the local network is sent to the centralized observation point (CMS) to other consumers.

Control commands, voice communication and sound notification from the side of the centralized observation point are sent through the switch to the communication module. From the communication module, the information goes to the corresponding controllers of the signal processing unit, from where, after conversion, it goes (through the backplane connection) to external devices.

The server remains operational when the input voltage is from 160 to 250V. A network protection module is installed at the server entrance, which protects the server from impulse surges at the 220V input. It is a self-healing device, with protection against impulse surges within the specified parameters. Structurally, the module is located on the right side of the inner cabinet, above the input machine. The ~ 220 V mains indicator of the module is brought out to the outside of the inner cabinet.

The input voltage monitoring sensor is an electronic relay with dry contacts and photocoupler isolation. When the mains voltage is normal, the output contacts of the module are closed. If the voltage drops below 160V, the contacts open. The LED on the module board is on when the mains voltage is normal, blinks when it is undervoltage and is off when there is no voltage. The output of the input voltage control sensor is connected to the terminals of the communication module, which transmits information about the state of the input voltage of the server to the automated workstation of the control panel on duty.

The server cross is designed to switch all signal lines and power circuits of external devices:

- video cameras of external and internal design;

- a fire alarm control panel (PPKOP);

- alarm loops;

- security detectors;

- emergency call devices;

- controlled devices;

- analog telephones.

The cross is located at the bottom of the outer casing of the server. The connection boards of the corresponding processing modules are installed in the cross. Connection boards carry out switching of external circuits, as well as protection of circuits from induced impulse voltage. The commutation of the modules connection boards (backplanes) is carried out by flat cables with IDC connectors.

The signal processing unit (BFB) is designed to receive and process signals from the peripheral devices of fire and security alarms, CCTV and access control, and transmit control commands from the centralized observation point to the peripheral devices.

Biofeedback is built on a modular basis. Each module included in the biofeedback system has a specific functional purpose. If it is necessary to increase the number of parameters in the CCTV function (for example, the number of video cameras), it is enough to increase the number of corresponding video modules. This provides a flexible construction of an integrated security system for specific customer needs.

The BFB includes:

- backplane with 15 slots for connecting modules;

- communication module;

- power module MP-1.

To expand the functionality, the server is supplemented with expansion modules included in the delivery set, determined by the necessary functions:

- power module MP-3;

- hub module (RS-485 interface) - MK;

- module for monitoring loops and voice communication - MS;

- loop and access control module - MShD;

- module for monitoring loops and voice communication - МШРС;

- access control module MKD-624

- video signal receiver module for 4 channels - PVS-4;

- module of switching of warning signals MKSO-.

The communication module (MC) is designed to collect information from signal processing modules, convert it to the 100Base T Ethernet protocol and transfer information through the switch to the local network. In addition, the MS monitors the opening of the server door and digitizes the input voltage sensor signal. This information is also transmitted via the local network to the monitoring station.

The MP-1 power module is designed to provide the necessary supply voltage for the modules installed in the biofeedback system, as well as other devices. MP-1 generates stresses with a value of 5; 7.5; 12; 27 V and current, respectively 1.5; 1.5; 1.0; 1.1 A.

MP-1 has configurable outputs "5/7, 5/12" and non-configurable outputs. The setting of the output voltage of the tunable output of the power supply is made by closing the corresponding contacts of the XP1 connector with a jumper. When the jumper is not installed, the output voltage of the terminal block is set to 5 V.

The MP-3 power module is designed to power Ethernet switches, video servers and other devices with a voltage of 5; 7.5; 12 V and current, respectively, 1.5; 1.5; 1.0 A. 19

The MP-3 includes 3 switching power supplies with configurable outputs. The setting of the output voltage of the tuned output of the power supply is made by closing the corresponding pins of the connectors with a jumper. When the jumper is not installed, the output voltage of the terminal block is set to 5 V.

The concentrator module (MC) is designed to collect information messages via the RS-485 interface line from the address Control Panel and transmit control commands to the Control Panel, as well as to ensure the exchange of voice messages between the monitoring station and the Control Panel.

The converted information from the Control Panel goes to the communication module and then to the switch.

MK has 4 ports of the RS-485 interface with elements of the second stage of protection against voltage induced in the line (lightning protection).

The module for monitoring loops and voice communication (MShRS) is designed to control loops of security and fire and alarm systems, organize two-way addressable voice communication with intercom devices and transmit warning signals to MKSO-4.

The loop and access control module (MShD) is designed to control the loops of the security, fire and alarm signaling and control relay contacts.

The backbone switch is designed to collect information from all Ethernet ports of the server and transfer them to the local network to the AWS.

Load control board (PUN) is designed to switch the supply voltages of the server modules. In the server, this board switches the supply voltage of video servers and the supply voltage of video cameras.

PUN consists of two relays, controlled remotely from the AWP. Relay control settings are made in AWS ABD. Upon command from the AWP, the relays can turn off the power of video servers and video cameras to reduce the current consumption when operating from a backup power source. PUN communication with AWP is carried out via Ethernet. The configuration of the IP address of the PUN is performed using the "ncp.exe" program similarly to the configuration of the IP address of the communication module of the new sample.

VOIP gateway is used to connect analog phones to the IP telephony system. The VOIP gateway has 4 FSX ports for connecting analog phones and an Ethernet port for connecting to a switch.

The temperature controller unit and the heating board are designed to maintain the temperature regime in the internal compartment of the server within the range from 0 to + 60 ° C.

The temperature controller unit performs the following functions:

- generates a voltage of 220V to the heating board when the temperature in the inner compartment of the server drops below 0 ° С;

- generates a voltage of 27 V to power two cooling fans when the temperature in the internal compartment of the server exceeds + 38 ± 3 ° С;

- turns on the server (supplying 220 V voltage to the power source) at negative temperatures only after the server warms up using the heating board and the temperature in the internal server compartment reaches 0 ± 3 ° C.

Mains voltage 220 V with a frequency of 50 Hz is supplied through a circuit breaker to the thermostat unit. Next to the mains switch is a mains indicator with a lightning protection board.

When you turn it on for the first time, if, when the server is powered up, the temperature in the internal compartment of the server is below 0 ± 3 ° C, then the voltage of 220V is supplied only to the heating board, while the power source for the rest of the server equipment is disconnected from the network. As soon as the temperature in the inner compartment of the server exceeds 0 ± 3 ° C, the thermostat unit supplies 220 V voltage to the server power supply and at the same time disconnects the voltage from the heating board. Further, when the temperature in the inner compartment drops below 0 ± 3 ° C, the heating board will turn on without disconnecting the server power supply. The server performs a number of functions:

1. The design features of the housing allow to protect the electronic equipment located inside from external influences. The server is designed for work at temperatures from minus 50 to plus 50 ° С. At the same time, if it is easy enough to protect against negative temperatures (pasting the inner case, installing heating, then these same solutions become a problem at high positive temperatures.

The solution for plus 50 ° C is that the inner case is almost completely isolated from the outer one and is attached to it at 4 points. In this case, the outer casing becomes divided into two halves when the inner casing is installed.

As a result, when the temperature in the inner case rises, two fans turn on. One inlet, the second outlet. The exhaust begins to draw hot air out of the inner case. Hot air, getting into the outer case, according to the law of physics, rises up and in contact with the outer walls of the outer case cools down. Further, going down, it is drawn into the inner case by the supply fan. This is how cooling takes place. Tests have shown that with this ventilation method, the temperature difference between the outside and the inner case reaches a maximum of + 10 °. Additional protection from direct sunlight is provided by screens attached to the outer casing.

All electronics are located in the inner case of the server. Due to the maximum integration, one server can solve tasks for security and alarm systems, access control systems, voice communications, warning systems, video surveillance systems, emergency lighting control systems or any executive devices on a perimeter section up to 800 meters long. This figure is obtained based on the number of video cameras connected to one server - 20 pcs. and the step of installing video cameras - 40 meters.

The server also provides power to all connected peripherals. With a wide range of power supplies (DC 12V, 24V, 48V), it can power almost any connected equipment. Moreover, the number of power outputs is almost equal to the number of inputs for connecting equipment. This means that each consumer can be powered from an individually protected power outlet.

The server can work with both analog and digital devices. Since the peripheral market is quite saturated, we give the opportunity to connect almost any device chosen by the customer.

The modular design of the controllers simplifies server repair and reconfiguration. Any of the controllers can be freely rearranged into any of the servers. In addition, dividing the controllers into two modules, one of which is a connection board with terminals for connecting the periphery, and the other a board with "brains", allows replacing a failed controller without having to disconnect all wires coming from outside. This greatly simplifies and speeds up the repair work.

The use of optical communication lines and the digitization of all analog signals in the server allows transmitting all information about the connected peripherals and giving commands for control, diagnostics or configuration from an automated workstation located tens and hundreds of kilometers from the server. In fact, it is necessary to bring two lines to the server, one for 220 V power supply, and the second for communication - optics. With a L2 backbone switch, the servers can be combined into a ring. Moreover, each of the servers can be used as a repeater of signals from previous servers.
