2. description of the object and requirements of the technical assignment

2.1. Brief description of the protection object

The protection object is the Thermal Power Plant (CHP), located deep in the territory of the metallurgical plant. Production buildings and power electrical equipment are located on a common fenced area, while the external walls of the buildings replace part of the fence. The territory of the CHP is entered by vehicles and railway transport through the gate in the fence and the passage of people through the doors of the external sides of buildings and gates in the fence.

In addition to buildings on the main territory of the CHPP, there are two more buildings to be protected, located on the territory of the metallurgical plant outside the main territory - the office building and the administrative and household building. The service building is located across the road from the main territory of the CHPP, the administrative building is located at a distance of about 500 meters from the main territory.

On the territory of the metallurgical plant there are cable and pipe metal racks connecting many buildings and structures to each other. On the territory of the CHP there is an open switchgear (ORU), with lighting masts, lightning outlets and cable structures located on it.

Many mill enclosures have a local area network that provides a centralized digital connection between any connected objects.

2.2. Purpose and scope of the system

The designed engineering and technical security system is intended to ensure the anti-terrorist security and safety of the power supply facility. The tasks of the designed system in accordance with the terms of reference are:

• Provision of 24-hour remote visual control over remote areas of the territory;

• Identification of facts of illegal actions in the early stages of their commission;

• Ensuring prompt response to illegal actions;

• Increasing the volume of useful information on emergency situations for their subsequent analysis;

• Improving the security and safety of equipment.

The system includes a television surveillance subsystem, a lighting subsystem and an access control subsystem.

Considering the presence of a security service and a pass mode at the metallurgical plant, in the absence of an independent security service at the protection facility, the designed engineering and technical safety system should be integrated into the existing plant safety equipment system.

2.3. Requirements for television surveillance subsystem

In accordance with the requirements of the technical specification, the subsystem should be built on the basis of the Intelligence software of the Russian company ITV. Analog color and day/night video cameras, including controlled rotary cameras, should be used to generate video images.

To transmit video images, video transceivers should be used over symmetrical communication lines (twisted pair). For registration, storage and delivery to remote workplaces - a video server based on a computer with installed software. The output of current and archived video images is provided for two remote monitoring workplaces connected to the video server through the local computer network of the mill. It shall be possible to control rotary video cameras from these remote workplaces.

Power supply of the subsystem must be provided from uninterrupted power supply sources, which provide a battery life of at least three hours. The duration of storage of the subsystem video archive must be at least 30 days.

2.4. Access Control Subsystem Requirements

In accordance with the requirements of the technical specification, access control should be equipped with fourteen access points - seven access points in the external fence of the CHP territory and seven points - doors at the entrances to buildings and inside buildings.

Access points should provide the ability to both enter and exit through contactless access cards available to employees. In addition, it should be possible to remotely open access points from the dispatcher's seat and automatically unlock in accordance with the fire alarm evacuation plan. All events occurring in the access control system must be logged on the access system server. Power supply of the subsystem shall be provided from uninterruptible power supply sources, which provide a battery life of at least three hours.

2.5. Interface with existing systems

In accordance with the specification, the following compatibility requirements are imposed:

• The television surveillance subsystem shall be integrated into the existing CCTV system of the metallurgical plant;

• The access control and control subsystem shall be integrated into the existing steel mill access control system;

• power supply of subsystems is provided from the existing power grid of the CHP buildings.

3. technical decisions adopted in the project

The main technical decisions of the project are made in accordance with the requirements of the technical specification, taking into account the changes made to it.

3.1. Technical solutions of television surveillance subsystem

Analogue stationary and rotary video cameras of street design, located on the supports of existing racks, walls of buildings and metal structures and stationary video cameras of dome internal design, installed indoors on ceilings and walls, are used to form video images. Video information is collected and archived by the server based on a computer with a sixteen-channel video input card and Intelligence software installed in it. The transmission of video images, with the exception of a video camera in an administrative building, is carried out in analog form via multi-dimensional twisted pair signal cables using specialized transceivers for symmetrical communication lines based on one pair of cores for one video signal. To protect transmitted video signals from electromagnetic motions, a set of measures should be implemented, including the correct implementation of equipment grounding, the elimination of "earth loops" in signal lines by galvanic isolation, shielding cable lines with the connection of the screen to the ground only from the receiving equipment and the separation of signal and power cables during parallel routing.

The above cables are laid on existing cable racks, building walls and newly laid overhead lines. Rotary video cameras are controlled by the RS485 interface transmitted through one of the pairs of the same signal cable, using only one pair for the RS485 interface in each cable, regardless of the number of video cameras connected to it.

Control of rotary video cameras will be configured with a priority system and patrol mode. The patrol mode is recorded in the memory of the video camera when setting up the system and in the absence of commands from operators of remote workplaces, the video camera regularly inspects its territory, moving along the stored route. When commands are received from operators, the video camera switches from patrol mode to manual operator control mode. If there are no commands from the operators for a given time, the video camera automatically returns to patrol mode again.

For the building of the administrative building, given its great distance from the rest of the buildings and the presence of several road and railway tracks separating it from the main territory, video images are transmitted over the existing local network of the plant in digital form. To digitize the video signal from the video camera of the administrative building, a specialized video encoder compatible with the software of the television surveillance subsystem is used.

Two remote monitoring workstations are created on the basis of computers with specialized software installed on them, which ensures the exchange of information with the central server of the subsystem over the existing local network of the mill for the ability to view current and archived video images, control rotary video cameras.

Close to street video cameras there are sealed street steel cabinets, which house twisted pair video transmitters, DC power supplies, lightning protection devices for power and interface lines, circuit breakers and plinths for switching multi-pair cables. Protection against adverse environmental impacts of street cabinets is ensured by the tightness of their design and the introduction of all cables through sealed leads. Heating of video camera cabinets is not provided, since all the equipment located in them is designed to work in a wide temperature range. Lightning protection of video signal transmission lines is carried out directly by the used transmitters and receivers themselves over a twisted pair.

Since all internal video cameras are located together with access control subsystem access points, the auxiliary equipment required for their operation (transmitters and power supplies) is located in MCDS controllers cabinets together with controllers.

3.2. Equipment of television surveillance subsystem

As seven street rotary video cameras, video cameras of the EPTZ830 model manufactured by EverFocus are used. This high-speed dome street waterproof (IP66) video camera has "day" and "night" modes with a switchable cut-off IR filter.

This day/night street video camera has a resolution of 550 TVL, a photosensitivity of 0.12lx in day mode and 0.06 lx in night mode, is equipped with a 2.811 mm variofocal lens with an ARD. Serviceability of the video camera at temperatures from 50 ° C to + 50 ° C. Power supply of 12V DC at power consumption not more than 7V.

As four internal color video cameras, dome video cameras of the ED350HQ/PV9 model manufactured by EverFocus are used. This video camera has a resolution of 560 TVL, a photosensitivity of 0.5lx, a variofocal lens of 2.8mm10.0mm. Serviceability of the video camera at temperatures from 10 ° C to + 50 ° C. Power supply of 12V DC or 24V AC at current consumption not more than 300 mA .

For power supply of stationary video cameras, power supply units of street version of BP3AG manufactured by Teleinformvyaz are used. This power supply in the sealed plastic housing of version IP56 provides power supply of 12V with current up to 3A in the range of ambient temperatures from 30 ° C to + 40 ° C.

To protect the RS485 interface lines of rotary video cameras from overvoltage induced during thunderstorms, Tahion UZLs are used. This device is designed for attachment to a DINrake, has a protection category C2 at rated discharge current up to 2kA, overall dimensions 89x58x35mm, temperature range from 55 ° C to + 85 ° C.

To protect 220V power lines of the system from overvoltage induced during thunderstorms, UZP220 devices manufactured by Tachion are used. This device is designed for attachment to a DINrake, has a class III protection category at rated discharge current up to 3kA, overall dimensions 86x58x35mm, temperature range from 40 ° C to + 80 ° C.

To transmit video images, sets of active transceivers with built-in lightning protection manufactured by Tahion are used: one set of the APVS3M model for distances up to 500 meters and four sets of the APVS5M model for distances up to 1100 meters.

To input video signals to the computer system, the ITV FX116 video input card is used, which provides input to the computer of up to 16 channels of multiplexed video image with a resolution of up to 704 × 576 pixels with a frame rate of 8 k/s on each channel. The video input board is installed in a server with Intelligence software installed on it, the server configuration is recommended by the software manufacturer.

3.3. Access Control Subsystem Technical Solutions

To implement the access control subsystem, Parsek equipment is used with contactless card readers compatible with access cards used in MCDS of the metallurgical plant. Each employee will have only one access card, one for the passing mill and for the passage points of the CHP, but the databases of these two systems will not be connected to each other, after issuing a pass to the pass office of the mill, it will be necessary to manually enter this pass into the MCDS CHP database.

Only eleven access points are equipped with access control - six doors at the entrances to the buildings/premises and five gates located in the perimeter fence of the territory. Two readers will be installed at the points of passage - to monitor passages in both directions of movement; and at two points - the entrances to the room of the main panel of the CHPP, there will be an entrance by reader and an exit by button .

To ensure fire safety requirements, four access points to the buildings located on the escape routes will be additionally equipped with manual emergency door unlocking devices from the inside. To block the passage through the doors and gates, overhead electric locks will be used, providing guaranteed unlocking of the passage in case of power supply or equipment malfunctions.

To close doors after a person passes, the doors are equipped with door shimmers. To control the closing of doors and gates after passage, magnetic contact detectors are installed on them.

The operation of each pass point is controlled by a specialized MCDS controller, which stores data on allowed access cards, compares cards presented to readers, decides whether to present or not access through the pass point and sends information on all registered events to the central server of the system.

To combine all points of passage (except for passage to the administrative housing) into one information system, the RS485 interface of the star topology is used with a serial connection of controllers with a common bus in each beam of the star. Two twisted pairs of the same multipath signal cables used in the video surveillance subsystem will be used to transmit the interface. A specialized central controller is designed to combine several interfaces and connect them to the MCDS server. To connect to the MCDS server, the passage point located in the building of the office building is used by the existing local network of the mill, using the network model of the controller connected through Ethernet for this passage point.

To store the MCDS database and log all events occurring in the system, a server with specialized ParsecNET 3.0 software installed in the server service chassis is used. To create a remote workstation for making changes to the gap database, a software module of an additional workstation and a desktop reader are provided, which are installed on the remote workstation of the system.

At street access points for protection against weather impacts and external interventions, the controller and auxiliary equipment are installed in a specialized sealed steel thermowell. At the internal points of passage, the controller is protected by installing its and auxiliary equipment in a metal lockable cabinet.
