Description

FIELD OF THE INVENTION

The invention relates to the field of burglar alarms, in particular to monitoring systems that record the facts of passage of employees and unauthorized persons into the subway tunnel and track their further movement through the tunnel.

State of the art

A well-known mine system for monitoring, warning and determining the location of miners (patent RU 2401947, IPC E21F 17/18, publ. 10/20/2010), which contains installed in the mine working sensors recording the location and direction of movement of miners, mobile video and infrared cameras, a device for recognizing and generating control commands, terminals of operators monitoring the background of mine workings and the location of miners and controlling the operation of the system. Miners are equipped with transponders and individual key chains. A device for recognizing and generating control commands, as well as a database for it, are implemented in a computer. The database includes information about the location of the sensors, the coordinates of the request-response devices, individual transponder codes and the owners identified with them, threshold parameters of emergency situations, modulation parameters of individual beacon code signals of the remote control. Movable video and infrared cameras are located in the mine working area, with the help of which it is possible to control the situation in the mine, as well as devices for activating individual key fobs and recognizing individual beacon code signals of key fobs radiation in the acoustic, radio and infrared wavelengths. All sensors, transmitting and receiving devices, recognition devices, activating individual remote controls, mobile video and infrared cameras are connected to a recognition device and generating control commands.

The system has a complex configuration, as it is intended not only to alert and determine the location of miners, but also, according to the present invention, allows to implement safe working conditions for miners with a high degree of reliability, as well as to recognize programmed dangerous situations.

A device for monitoring and passage into the tunnel (UKPT) (metroworld.ruz.net) is known. The UKPT and UKPT-MR have control and signaling devices that have two main operating modes: the alarm mode and the security mode. The principle of operation of UKPT and UKPT-MR is based on the intersection of obstructing infrared rays and infrared barriers. In the schemes that are included in the operation during the construction of metro stations, only the IR barrier is used, but still a significant part of the stations and metro ramps are equipped with UKPT and UKPT-MR using a beam rather than a barrier. In all the controlled entrances to the tunnel, there is an infrared ray that is invisible to the naked eye, at the intersection of which there is a violation of its continuity, which results in the transfer of the UKPT or UKPT-MR signal device to the “alarm” mode and a violation message is generated in the controlled area. After that, in the light and sound annunciator, the lamp is turned on in flickering mode, and the sirens in continuous operation.

A disadvantage of the known device is:

- penetration control is carried out only at the entrance to the tunnel;

- The infrared beam is small in size and, with certain skills of the intruder, can be bypassed from above or from below;

- control of the location and movement of people inside the tunnel is not carried out.

Utility Model Essence

The technical task of the proposed solution is to create a system to ensure the safety of metro infrastructure facilities by quickly detecting the facts of unauthorized entry into tunnels, on land sections, park and depot roads, controlling the movement of tunnels in and out of them, and unauthorized persons.

The technical result, which is achieved using the invention, is to increase the degree of technical security of infrastructure facilities of tunnel structures and, as a result, enhancing the safety of passenger traffic.

The specified technical result is achieved due to the fact that in the system for controlling passage and movement in the tunnel, including control and signaling devices, according to the proposed solution, a dome camera with infrared illumination is installed at the entrance to the tunnel, equipped with software that implements the functions of a motion sensor, determining the quantity passing people and the direction of their movement, while the output of the dome camera is connected to the input of the switch for transmitting data via Ethernet, which interacts connects to the telecommunication server and the dispatcher workstation, and an input detector, one output of which is connected to the input of the data transmission module, the output of which is connected to the second input of the switch for data transmission via Ethernet, the other output of the input detector is connected to the input of the light-sound siren, inside the tunnel at least one detector has been installed at the borders of control zones with a length of 50-500 m, while the detectors are connected in series with each other and interact with the input detector, the input detector and detectors with hold two single-channel volume radiowave motion sensor, whose outputs are connected to respective inputs of the sensor module with its connected identifying the RFID reader.

A brief description of the drawings.

The invention is illustrated by drawings, where in FIG. 1 is a structural diagram of a system for controlling passage and movement in a tunnel; FIG. 2 is a structural diagram of a detector.

The implementation of the invention

The system (Fig. 1) includes, installed at the entrance to the tunnel, the dome camera 1 and the input detector 2. The output of the dome camera 1 is connected to the input of the switch 3 for data transmission via Ethernet, which communicates with the telecommunication server 4 and AMP of the dispatcher 5. One the output of the input detector 2 is connected to the input of the data transmission module 6, the output of which is connected to the second input of the switch 3, and the second output of the input detector is connected to the light-sound siren 7. Inside the tunnel, connected in series from broadcasters 8, which form control zones and interact with the input detector 2. Radio tags 9 emit signals identifying employees that are received and recognized by the detectors 2, 8.

The detectors 8 (Fig. 2) consist of a sensor module 10, the first and second inputs of which are connected to the corresponding outputs of the single-channel volumetric radio wave motion sensors 11 and 12. A sensor reader 13 is connected to the sensor module 10, one output of the sensor module 10, which the output of the detector 2 is connected either to the input of the data transmission module 6 (in the case of the detector installed at the entrance to the tunnel) or to the previous detector. A light-sound siren 7 (in the case of a detector installed at the entrance to the tunnel) can be connected to the second output of the sensor module 10. The fourth input of the sensor module 1 can be connected to the output of the next detector in the chain 8.

Concrete example

At the entrance to the tunnel, an input detector 2 is installed and video camera 1 is located as close as possible to the upper point on the tunnel arch with an offset of no more than 30 ° from the normal 1. Inside the tunnel, detectors 8 are located inside the tunnel, providing for recording facts of people moving past them and registering codes identifying devices.

To determine the belonging to the subway employees of persons in the tunnel, individual identification devices 9 (active RFID tags) are used. The radio signal emitted by the identification device 9 contains a unique identification code having a high degree of protection against counterfeiting and modification and is assigned to the employee and uniquely identifies him.

The control line at the entrance to the tunnel is a section of the tunnel along its entire length 5-8 m from its beginning, on which entry and exit control is carried out. When a person crosses the control line at the entrance to the tunnel, the detector 2 records the fact that the person crosses this control line and determines the direction of its movement, also reads the identification parameters of the employee and transmits this data via the communication line to the monitoring telecommunication server 4. The operation of the motion sensor 11, 12 in the detectors 2, 8 is based on the effect of the Doppler frequency shift of the emitted microwave signal reflected from moving objects. Between the adjacent control lines inside the tunnel there are control zones, the length of which depends on the characteristics of the controlled sections of the tunnel, and can range from 50 to 500 meters. If a person crossed one of the control lines at the border of the zone, then before he crosses the control line at the other border of the zone, he is in this control zone.

With the help of video camera 1, the fact of a person crossing the line at the entrance to the tunnel is recorded, and people who have passed in each direction are counted. The camcorder 1 also records on the built-in video storage device for a set time interval corresponding to the event of crossing one or several people controlled by it. Data from the video camera 1 is transmitted via a communication line to a telecommunication server 4, where they are accumulated and processed. The viewing angle of the camera 1 is set in such a way as to provide control of that part of the tunnel where people can pass. Video recording of the facts of people’s passage is carried out on a flash drive built into the camera with subsequent automated transfer of data to a special storage of video files. Data storage from detectors and video cameras is carried out using a DBMS.

Telecommunication server 4 processes the information received from the detector 2 and video camera 1 about the facts of people crossing the control line at the entrance to the tunnel and from the detectors 8 control lines inside the tunnel, as well as about the identification parameters of employees crossing such control lines, generates alarm messages if necessary on APM attendant 5, and also activates a light-sound siren 7, accumulates control results in the database.

On duty station AWP 5, information on the facts of the crossing of a control line by an employee or an intruder is displayed in graphical and tabular forms, data on the number and direction of movement of people are displayed, and the current image from the camera of the control line at the entrance to the tunnel is displayed. It also provides the ability to display previously recorded camera video images tied to alarm camera events displayed on the screen registry.

Thus, the application of the proposed solution allows automated control over the entrance to the tunnels, the movement of metro employees and unauthorized persons into and out of them. To determine the number of people who entered and exited, to determine their location in the tunnel, as well as to identify subway employees who are in the tunnel, a control line at the entrance to the tunnel and control lines inside the tunnel are organized.
