Description

The invention relates to the field of railway automation, telemechanics, communications, is intended to alert workers on the station's railway tracks of approaching the railway rolling stock, and is designed for use in the structure of the park communication system at railway stations of any class, freight yards, depots, industrial enterprises and other railway facilities.

A well-known centralized integrated passenger information system, alerts for people working on railroad tracks and station park communications, containing in the control center a central information server, centralization dispatch system, database, dispatcher console, hardware-software device for the information-control system of dispatch control trains, automated workstations of the system manager and administrator of the monitoring and administration system, telephone numbers onki at each station and stopping point, on the stage at the place of repair work, containing a collective portable siren equipped with a receiver of navigation signals and a transceiver connected via a GSM-R radio communication network with the corresponding output of the information-control system for controlling the movement of trains (RU, patent No. 2497176, G06F 3/00, G06Q 50/00, 2012).

The disadvantage of this system is the transmission of control signals about the absence of rolling stock and notification of its approach along the feeder lines of loud-speaking park communication and their audibility over a large territory. These signals can be received by another repair team, to which these signals do not apply, while creating false ideas about the lack of rolling stock and reducing the safety of repair work on railways. In addition, a loud-speaking warning interferes with residents of residential buildings surrounding the railway park.

The Siren system is known for alerting track crews about the approach of a train, which records the location of the team through the use of satellite navigation and radio communications between the leader of the track crew and the locomotive driver (“The concept of improving traffic safety through the use of multifunctional complex train control systems on railways” Moscow, 2006, p. 92).

The disadvantage of this system is that the location of the track crew is not localized in the general control system, and in the absence of prompt notification of the track crew because of the need to pre-conduct manual exchange between the leader of the track crew and the train operator of an approaching train.

The closest in technical essence is a monitoring and notification system for the approach of rolling stock, containing a central control center in which are installed interconnected application server and GSM radio server, on-board units of mobile units of rail transport, each of which includes an integrated locomotive safety device connected by two-way communication to a notification node with a GSM radio transceiver, individual warning blocks, each of which consists of a mic the processor module of the GSM radio transceiver, track control units installed near the rails at the points of point monitoring of the proximity of the moving units of the rail transport to the place of track work, each track control unit consists of a self-testing track sensor for passing the wheels of the moving units of the rail transport, connected by two-way communication a transceiver of combined GSM / GPS radio communication and a transceiver of a self-organizing network, to each individual notification unit I introduced a microprocessor-based transceiver module of a self-organizing communication network and a switch for setting the operating mode, while one data port of a microprocessor-based transceiver module of a self-organizing communication network is connected to the data port of a microprocessor module of a GSM radio transceiver, and its other data port is connected to a switch for setting the operating mode (RU 2467902 C1 , B61L 23/06, 11/27/2012).

The disadvantage of this system is the need to use a central control station (dispatcher) if there is a rolling stock on the site that is not equipped with a complex locomotive safety device that provides GSM radio communication, as well as the lack of periodic monitoring (every 12-15 seconds) for the system is in good working order and there is no objective confirmation of playback warning signals by individual warning blocks.

The objective of the present invention is the creation of a reliable and effective warning system for workers on the railway station of the approach of rolling stock, not equipped with a complex locomotive safety device that provides GSM radio communication.

The indicated technical problem is solved by a warning system for stations operating on the railway tracks, containing a control controller connected to a stationary warning radio station and designed to connect to the station system, and individual wearable sirens and characterized in that it is equipped with collective portable sirens, each of which includes a controller and the transceiver connected to it for radio communication with a stationary warning radio station, a navigation receiver for reception of GLONASS / GPS system signals and a transmitter for transmitting radio signals to individual wearable sirens.

The technical result achieved by the proposed invention is to provide alerts working on the station’s tracks about the approach of rolling stock on the basis of information about its approximation received from the park communication systems (SS) of the stationary transceiver (stationary warning radio station - SRO) associated with the collective portable radio channel sirens (KPO), reproducing sound and optical signals, and individual wearable sirens (INO), switching into vibration and playback mode nagging sound and optical signals.

The system is designed to notify station workers on railway tracks of the approach of railway rolling stock on the basis of information received from station systems of railway automation and telemechanics (such as the MPC - microprocessor-based electrical centralization system or LITTLE - shunting automatic locomotive signaling) included in the park communication structure.

Alerting is carried out using an autonomous system containing a stationary radio station of the 160 MHz band (SRO - stationary warning radio station), a stationary control controller (UKS) and a signal panel (SP) of the station duty officer. The corresponding SS outputs are connected to the UKS.

In contrast to the known system (RU 2467902 C1), in which a public mobile communication network is used for communication between the elements, the proposed system for communication uses the allocated technological communication frequencies of the Russian Railways (151.7-156 MHz), which eliminates the dependence on the network status (workload, etc.) of a third-party organization.

Thus, increasing the reliability and efficiency of alerts working on railway tracks about the approach of rolling stock is achieved due to the following factors:

- use of information from existing SS;

- the use of communication channels based on technological radio communications;

- the use of collective portable devices with the GLONASS / GPS navigation system to receive alerts at a specified place for repair work;

- use of one frequency for communication with all KPO;

- use of portable individual sirens;

- local notification at the work sites and the use of wearable individual sirens do not create acoustic interference for residents of residential buildings surrounding the railway park;

- ensuring continuous monitoring of the functioning of equipment and communication channels.

In FIG. 1 presents a structural diagram of the proposed warning system (SOPR-160).

In FIG. 2 presents an algorithm for exchanging information in the proposed warning system.

The structure of the warning system for workers on the railway tracks of the station includes:

- a stationary set of equipment, comprising: a stationary warning radio station 1 (SRO), a station control controller 2 (UKS) connected to it, and a signal panel 3 of a station duty officer (SP) connected to UKS 2;

- collective portable sirens 10 (KPO), each of which includes a transceiver 6 (PP), a navigation receiver 7 (NP) and a transmitter 8 (Tx), connected to the controller 11;

- individual wearable sirens 9 (INO).

The system through a stationary radio station 1 is connected to a station system 4 (SS), including a workstation 5 (AWP).

To alert workers, an analogue radio station CPO 1 is used, interfaced through the UKS 2 control controller with a station system 4, which includes an automated workstation 5. UKS 2, together with a signal panel 3, is installed at the station duty station workstation.

It is connected to the SRO 1 via the KPO 10 radio channel, which, in turn, is connected via the radio channel to the individual wearable sirens (INO) 9. Each KPO 10 is equipped with a certain number of INO 9 interacting with it.

The proposed SOPR-160 system assumes that there are 5 KPO units at the station. All work areas at the station are indicated by numbers 1 through 5, which are entered in the CC 4 system. In FIG. 1 conventionally shows two KPO 10: KPO-1 and KPO-2. For the interaction between SRO 1 and all KPO 10 at the station uses one frequency. Before starting work at the request of the foreman, the station duty officer enters the work zone number through AWP 5 into SS 4. The specified unique zone number is set by the forerunner on the KPO 10 keyboard. When setting the zone number in KPO 10, the coordinates of this zone are automatically set received from the navigation receiver NP 7 connected to the GLONASS / GPS network.

In the absence of rolling stock when placed in the KPO 10 work area, the PP 6 transceiver unit receives control signals from the CPO 1 and GLONASS / GPS navigation signals through the NP 7 navigation receiver unit.

If the coordinates received from the GLONASS / GPS network coincide with the coordinates set in KPO 10 for a given zone and if all the KPO 10 nodes are in good working order, acknowledgment signals are generated in the controller unit 11 and transmitted using PP 6 to CPO 1. On the signal panel SP 3 at the station duty officer this indicates the normal operation of KPO 10. At the same time, KPO 10 transmits a control signal to the INO 9 through the transmitter unit PRD 8.

The control signals are reproduced through the speaker 12 KPO 10 and through the speaker INO 9 every 10-15 seconds (an interval equal to the period of re-inclusion of the first time interval).

Upon detection of rolling stock approaching the work area from SS 4, the transmission of the work area free command ceases and commands to turn on alerts begin, which are transmitted through CPO 1 to KPO 10.

When reproducing the warning signals through the speaker 12 from the controller 11 through the transceiver 6 to the stationary radio station 1 alerts are sent acknowledgment signals containing messages that cause the corresponding signaling to be activated on the signal panel 5 of the station duty officer.

The alert signal has a duration of 2 seconds with a repeat period of 4 s. The notification shall continue until a zone free command is received from the station system 4.

In the event of a communication failure, if the speaker D 12 is malfunctioning (controlled by the microphone M 13), when KPO 10 is removed from the specified zone and other failures, KPO 10 and INO 9 are played through the speaker 12 with a warning signal lasting 1 minute, and a malfunction signal is displayed on the signal panel 3 on duty KPO 10 in a specific area of work.

In order to make it possible to use one radio frequency to organize the simultaneous notification of workers in several zones of the station when there are up to five KPOs 10 for communication of SRO 1 with each KPO 10, a radio communication protocol with time division is developed that takes into account all possible combinations of system states.

In FIG. 2 presents the algorithm for the exchange of information in the warning system (SOPR-160).

The repetition period of the time intervals of the radio protocol is not more than 12-15 seconds.

Each KPO 10 interacts with SRO 1 only in its own time interval (KPO-1 - in the first interval, KPO-2 - in the second, etc.). With an increase in the number of KPOs (more than five), the time interval can be reduced, for example, to 0.5 seconds.

The unique zone address is transmitted from SRO 1 in the corresponding time interval and is received by the KPO 10, which is located in the specified zone (on which the unique zone address is set).

Below are the characteristics of the nodes included in the proposed system SOPR-160.
