Description

The proposed utility model relates to technical means of protection and can be used to monitor the territory adjacent to the railway with the aim of detecting unauthorized movements of people in the protection zone and ensuring counter-terrorist acts.

A known system according to the patent of the Russian Federation 2137203, designed to control the flow of vehicles, containing digital cameras installed at various points, computers and / or servers connected via a local area network. In the memory of computers there are databases with the possibility of their analysis and comparison with images received from video cameras. The system allows with a certain error to identify individual search objects in controlled areas and register them. There is a system interface with the operator through the monitor at the checkpoint. In this system, cameras are fixed and have a limited viewing angle.

A known video surveillance system according to US patent 5982420, containing video cameras with a rotary device and a variable focal length (buzzer) connected to a computer. This system provides for the automatic pointing of the camcorder to an object falling into the controlled area. The system registers such an object and dynamically monitors it. The disadvantage of the system is the limited observation over distance.

Common disadvantages of these systems are:

1. The absence of technical means of detecting an intruder in the systems, which leads to the need for continuous analysis of a large amount of information from all cameras and imposes a limitation on the length of guarded borders controlled by systems.

2. The limited observation of the video camera over a distance that does not exceed 50 m, which requires the installation of a large number of video cameras at an extended controlled line and, as a result, leads to low reliability of the system as a whole.

The purpose of the utility model is to create a complex of protection for long sections of the electrified railway, which would eliminate the above disadvantages.

The technical result from the use of the utility model is to increase reliability and provide round-the-clock automated protection and television surveillance of the territory adjacent to the railway tracks in a wide range along the length of the observed security zone with a minimum amount of equipment used.

The technical result in this case is achieved due to the fact that:

1. The security complex includes successively located security sections with a length of 200 - 500 meters, creating a continuous security zone along the railway line. The basic set of equipment for each security section contains sensors for detecting intrusions into the protected area for detecting an intruder when approaching the railway track from one side or the other, a camera and a lighting device.

2. The camera is mounted on the support of the contact network of the electrified railway, made using a zoom device and provides automatic or, if necessary, manual mode for the operational monitoring of sections of the protected zone with a length of 50 - 500 meters in the visible and infrared (IR) range of light radiation. Lighting devices are infrared illuminators that are installed on the poles of the railway contact network after 50 meters and provide infrared illumination of the protected area in the dark.

3. Sensors for detecting intrusion into a protected area include means for detecting a target (intruder), configured to create a continuous extended detection zone for the entire security area and indicate the location of detection of a target at the security line, and the detection means, camera and lighting device are connected via trunk power lines and communication with the control panel of the security complex, which, in accordance with the specified algorithm, controls the guidance of the camera on the alarm section of the protected ones and the inclusion of infrared spotlights.

The essence of the utility model is illustrated by drawings in figure 1-2.

Figure 1 shows a cross section of a complex of protection of long sections of a single-track railway.

Figure 2 explains the concept of building a complex of protection of long sections of a single-track railway.

Figure 1-2 used the following notation:

1 and 12 - a barrier; 2 and 10 - means of detection; 3 and 11 - detection zone of the detection means; 4 and 9 - a precinct cabinet; 5 - television camera; 6 - IR floodlight lighting device; 7 - support contact railway network; 8 - railway track; 13 - zone of responsibility of the stronghold of the railway; 14 - control panel security complex; 15 - television surveillance area; 16 - luminous flux of an IR illuminator.

The same type of device is indicated in the drawings by the same reference numbers.

The proposed security complex for long sections of the railway includes up to 60 basic security kits and a control panel for the security complex and provides signaling blocking and television monitoring of the railway in the zone of responsibility of a strong point up to 15 km long.

The basic single-track rail security kit consists of:

- two barriers, one on each side of the railway track;

- at least two means of detection of the target, located so that on each side of the railway track there are at least one means of detection;

- cameras;

- lighting devices, including up to five IR spotlights;

- Two precinct cabinets, one on each side of the railway track.

The above structural elements of the basic protection kit are made as follows.

1. Barriers 1 and 12 constitute a physical obstacle that impedes the intruder from entering the security zone. Obstacles 1 and 12 can be made, for example, in the form of a fence with a metal sheet mounted on a supporting welded metal structure. As a metal sheet, a profiled sheet of type C8-1145-0.5 is used. The supporting metal structure is made of vertical posts installed in the ground at a distance of 3 meters from each other and the upper, middle and lower horizontal runs welded to them. Racks and runs are made of a profile of rectangular section 60 × 30 × 3 mm, length 3000 mm. Racks are fixed in the ground with concrete. The canvas consists of sheets 2 meters high and 1 meter wide, which are attached to the girders using self-tapping screws. Using a profiled sheet simplifies the installation of the fence in difficult terrain. The build-up is ensured by connecting the sheets in series with each other for organizing extended barriers on each side of the railway track.

2. As a means of detecting targets 2 and 10, vibrational, infrared, radar, capacitive, seismic, magnetometric detection tools installed on a fence or in the ground can be used and create an extended detection zone.

For example, a radio-beam detection means with a detection zone 3 of at least 250 m in length and at least 2 m in height from the earth's surface can be used. Its principle of operation is based on recording and analyzing changes in the amplitude of the transmitter’s electromagnetic waves received by the receiver. The receiver receives electromagnetic oscillations, analyzes the amplitude and time characteristics of the received signal and, in accordance with the specified processing algorithm, generates an alarm notification. The growth of the protection line is ensured by the installation of successive radio-beam detection means.

3. The camera 5 is mounted on the support of the contact network 7 at a height of ~ 6 m. It allows you to control approaches to the railway track 8 in the television surveillance zone 15 with a length of up to 500 m, made using a zoom device, has the functions of changing the focal length and aperture and focus when aiming at the target and provides observation of the protected area in the visible and infrared ranges of light radiation.

4. The lighting device includes up to five IR projectors 6, which are installed one on each support of the railway contact network at a height of ~ 5 m. IR projectors 6 provide IR illumination of the security line at night, forming light flux 16.

5. The precinct cabinet 4 and 9 is a metal cabinet with a door, inside of which there are places for fastening the electronic processing units that are part of the detection tools 2 and 10, and electronic units that receive video information from the camera 5 and control IR illuminators 6. Through the precinct cabinet, through the main lines, power is supplied to the basic security kit and connected to the control panel of the security complex 14. The main power and communication lines from the basic kit storage to the control panel 14 are laid in the ground.

On the side walls of the precinct cabinet 4 and 9, ventilation shutters are provided. A protective visor is installed above it to prevent the cabinet from heating up from solar radiation. At the bottom of the cabinet there are two openings for cable entry. To make internal and external connections, terminal blocks are installed in the cabinet. The precinct cabinet has supports fixed in the ground with concrete.

Basic security kits are installed sequentially along railway line 8 to create a strong point of the railway 13 of the continuous security zone in the zone of responsibility and are combined into a security complex using the control panel 14. Each basic security kit is assigned an address formed by binding this kit to the coordinates that determine the location of the base kit in the zone of responsibility of the railway stronghold 13. The indicated coordinates are expressed by the number of kilometers taken on yes hydrochloric rail kilometers reference frame portion and the path number in the range of one kilometer of road on which the base set of protection. For example, as shown in FIG. 2, the zone of responsibility of a railway stronghold 13 with a length of 15 km can be subdivided into kilometer segments, the binding of which is carried out to the kilometer of the railway track, which in Fig. 2 is conventionally marked with symbols from N kilometers to N + 14 kilometers. In turn, each kilometer section is divided into four sections according to the number of basic security kits installed on it with a length of 250 m. Thus, the addresses of basic security kits installed, for example, on the N-th kilometer of a railway track can be represented as N. 1 for the first guard at the N-th kilometer of the track, N.2 for the second guard at the N-th kilometer of the road, etc.

The control panel of the security complex 14 includes equipment for collecting and processing information coming from all security sites located in the zone of responsibility of the railway stronghold 13. It also includes an operator’s workstation equipped with a dial screen consisting of monitors on which information is displayed coming from the protected area.

The above-described complex of protection of long sections of the railway is used as follows.

They are preparing the security complex for operation. Carry out an external inspection of the equipment for proper installation and reliability of electrical circuits when the power is off. They turn on the power supply of the security complex and monitor the health of its equipment. To check the operability of the security complex, control actions are performed by simulating the intruder crossing the detection zones 3 and 11 of the detection tools 2 and 10 in all areas of the basic security kits.

Use the complex of protection of long sections of the railway as follows.

They include a security complex and organize around-the-clock duty of shift operators at its control panel. The functioning of the security complex is based on the formation of detection zones 2 and 10 of detection zones 3 and 11, at the intersection of which the intruder or a group of violators sends a signal to the control panel of security complex 14 with the address of the activated security section. When a response signal appears, the control panel 14, in accordance with the received address, identifies the location of the alarming section and sends a control signal to the camera 5 of this section. By the control signal, the camera 5 is automatically aimed at the alarming section of the protected area. The video signal from the camera 5 is transmitted via the trunk line to the control panel 14. Video information from the alarm section of the protected area is displayed on the screens of the control panel 14, which allows the security complex operator to objectively assess the alarm situation.

When a response signal appears in the dark, the control panel 14, in accordance with the received address, identifies the location of the alarm section and sends control signals simultaneously to the IR spotlights 6 and to the camera 5 of this section. According to the control signals, all IR illuminators 6 of this section are turned on and the camera 5 is automatically aimed at the alarming section of the protected area. The video signal from the camera 5 is transmitted via the trunk line to the control panel 14. Video information from the alarm section of the protected area is displayed on the screens of the control panel 14, which allows the security complex operator to objectively assess the alarm situation. The use of IR projectors and cameras capable of operating in the IR range provides high quality video information coming from cameras in the dark and does not have any effect on the operation of railway transport.

If necessary, video signals from any camera 5 of the protected zone can be manually displayed on the screens of the control panel 14 in order to clarify or assess the situation in the protected zone. Also, in manual mode, the inclusion of infrared spotlights 6 can be controlled on the selected section of the protected zone for viewing.
