The invention relates to the field of railway automatics and telemechanics and can be used during shunting on a dead-end track of the station as an additional means of improving traffic safety during shunting operations on a dead-end paths stations that are forced to stop when determining system dangerous approach shunting locomotive or composition with a stationary obstacle (travel stop) due to the automatic transmission to the locomotive command forced stop on the selected radio channel.

Known automatic shunting locomotive alarm (LITTLE), adopted as a prototype. System LITTLE is intended to ensure the safety of shunting on railway stations and prevent movement of the locomotive (composition) above the speed limit, and to automatically stop in front of the closed signal or place of work. The use of this system eliminates collisions of cars and locomotives at the stations and to prevent accidents due to errors of operating personnel. LITTLE includes station and locomotive equipment.

The main components of locomotive equipment LITTLE are: on-Board controller, the switch block, the block load indication and, the control unit, transceiver, and antenna.

The on-Board controller receives commands from the station apparatus through the transceiver. The controller polls the state of the electrical equipment of the locomotive through the unit and reads the information from the sensors. Information for the operator is displayed on the monitor screen of the display unit, and commands the driver enters into the on-Board controller with functional keyboard control unit. The locomotive apparatus can operate in three modes: manual, Autonomous and remote control.

As channel information transfer from stationary devices on the locomotive in the system is LITTLE used digital radio, operating in the range of 460 MHz. Digital radio system in conjunction with high-performance computer provides efficiency management locomotives and track their locations unreachable by traditional means.

Application software FOR avionics LITTLE is a standard DOS application running in real-time. BY continuously monitors the state of motion of the locomotive, keyboard, electric locomotive, data radio channel (telegrams Post) and displays it on the monitor information on the permitted speed, idamay speed on the next isolated sections, the number of free peredelami block sections, the distance to the first on-the-go insulated joint; the distance to the job site and to the end of route assignments; the prescribed mode of operation and a given route and other information. In critical situations the program affects the management of the propulsion engine and produces smooth or its emergency braking.

Control of information transmitted between the station and locomotive equipment is carried out according to the Protocol CRC32.

Functional safety LITTLE based on which was extremely important for the design of equipment both at the level of read data from relay electrical interlocking and data processing, user input and output of operational data, as well as management of moving objects over the air (see V. Zorin, E.E. Suhina, PV Titov "Microprocessor locomotive safety system trains a new generation of world Railways No. 7, 2003, p.61).

A disadvantage of the known system is the lack of resources to effectively avoid collision shunting composition path stops when settling on a dead-end platform path station wagons forward due to insufficient accuracy in the measurement of the distance from the blind end of the head car closer is eghosa shunting structure.

The technical result of the invention is to create a system for preventing collision of rolling stock or locomotive during shunting on a dead-end track of the station with a stationary obstacle (travel stop).

The technical result is achieved in that in the automatic system to force stop shunting locomotive when conducting maneuvers on a dead-end paths stations containing placed on the locomotive the locomotive controller connected to the remote locomotive, and a radio, a relay unit, intended for the opening of the electropneumatic valve forced braking and switching circuits control traction locomotive, located on a Central control point, the control device inspection, coupled with remote information, contact repeaters track relays electrical interlocking railway station, with the data hub and a wireless modem that provides radio communication with the locomotive equipment system according to the invention on a cul-controlled stops the track sections placed laser rangefinders, to determine the distance from the buffer stop before approaching shunting composition and entered controllers travel, which is connected to the data concentrator and the corresponding hole is rnym the finders.

Technical solution with the above combination of features allows you to prevent collision of rolling stock or locomotive with dead stop during shunting on a dead-end track of the station through the use of a laser rangefinder that provides high accuracy of determining the distance from the blind end of the rolling stock and the speed of its movement and due to the transfer command forced stop locomotive in excess of the permissible speed at a particular distance from the leading car up to the limit stop.

The invention is illustrated by drawings. Figure 1 and figure 2 presents the scheme of the automatic system to force stop shunting locomotive when conducting maneuvers on a dead-end paths stations.

Automatic system of forced stop shunting locomotive when conducting maneuvers on a dead-end paths stations includes a control device inspection 2 placed on the post electrical interlocking railway station and connected with contacts repeaters track relay electrical interlocking railway station (not shown), with the data hub 3 connected through the controller travel 4 with laser rangefinders 6, as well as through radio channels with the locomotive equipment is the Finance shunting locomotives. The data hub 3 is connected track equipment placed with travel stops on controlled dead-end paths.

On each locomotive placed the locomotive controller 8 connected to the remote locomotive 9, unit 7, the relay unit 11, connected to electric control circuits thrust of the engine and the valve is forced braking 10.

Track equipment placed with travel stops controlled dead-end roads, contains laser rangefinders 6, each of which is connected to the correct path controller 4 connected to the communication line to the data hub 3 via a wired communication line connected to the control device sentry 2, installed at the Central control point and connected to the radio modem 5.

Automatic system of forced stop shunting locomotive for shunting on a dead-end paths stations operates as follows.

On a cul-stop path is set to track equipment, containing the e laser rangefinder 6, directed along the axis of a dead-end railway track in the direction of approaching vehicles and the track controller 4.

The data concentrator 3 is designed to collect data from the laser range finder 6. Laser rangefinders 6 in the system can be up to 16 pieces. The data concentrator 3 dedicated wired communication lines connected with the equipment of the Central control point.

The control device inspection 2 is a Central processor of information and provides the processed data from the laser range finders 6 all dead-end roads on which they are installed. Produces a definition of acceptable speed shunting stock (locomotive) depending on the measured distance from the head up to the limit stop and the speed of the composition, and transmits as data on the locomotive and the teams on the use of forced braking maneuver in case of detection of a possible collision with dead stop dead-end road. Identify the possibility of collision is made on the basis of determining the value of the braking distance S shunting part of its motion speed V (Fig 1).

The locomotive equipment is used for interaction between the locomotive engineer and system using the remote locomotive 9. The locomotive controller 8 provides control equipment the investigation, unit 7 serves to organize, jointly with the radio 5 Central point of control channel data transfer between shunting locomotives and equipment Central control point. The relay unit 11 produces effects on the electrical control circuit of the traction engine and the valve braking force 10 from disabling the traction mode of the locomotive and run hard braking maneuver composition.

During the occupation of rolling stock, dead-end road data from the respective repeaters track relays electrical interlocking railway station is served by the control device inspection 2, which produces the appropriate laser rangefinder 6 installed on a cul-stop dead-end road. Laser rangefinder 6 starts to measure the distance S from the head coach (in the direction) of approaching shunting staff. The data rate of the distance from the laser rangefinder 6 to approaching head coach continually arrive in the control device inspection 2 through the data concentrator 3. The data used by the control device sentry 2 to determine the permissible speed shunting structure on dead-end road on the basis of the calculation table according to the stopping distance from a speed and number of cars.

The system provides the definition of a dangerous approach of a train with a stationary obstacle by comparing the actual speed V with a valid V depending on the distance S to the obstacle.

Permissible speed V is determined based on the braking distance for individual locomotives (depending on type) and shunting of trains (depending on length, weight, and other), and also taking into account the maximum delay time to the transmission of commands to force stop the locomotive from the moment of its formation to the moment acting on the brake and the traction equipment of the locomotive.

If V≥V, the system over the air via radio modem 5 transmits the command braking force on shunting locomotive, producing settling of the cars in this dead-end path.

Service information: permissible speed, the actual speed of the motion, the distance from the blind end of the head carriage shunting structure is transmitted to the locomotive radio and displayed for the operator of the locomotive to the remote locomotive 9.

Service information: permissible speed, the actual speed of the motion, the distance from the blind end of the head carriage shunting structure is displayed on the remote information 1 posted at the workplace of the head of shunting at the station (duty station)that allows you to control the movement of the stock on the dead-end road station. If the command execution is forced braking is enabled optical and acoustic signalling of the locomotive engineer and the head of shunting on railway station.

The system determines the speed restrictions shunting movements and if the actual speed shunting composition, calculated on the basis of data obtained from the laser range finder 6 will exceed the set speed on this section of road laid in memory of the control device of the constable 2, the locomotive engineer will be informed of the speed limit (optical and acoustic alarm).
