The station device of the shunting automatic locomotive signaling system integrated with the microprocessor-based centralization of the railway station operates as follows.

Information interaction between the systems of microprocessor interlocking and shunting automatic locomotive signaling and the vision subsystem is carried out through block 4 of the control and communication device. Linking the MPC with the MALS is intended to ensure the transmission of telesignaling signals about the state of the signaling devices at the station and the lines adjacent to the station to the MALS station equipment.

Information interaction between the control computer complex 5 MPC and the control computer complex 1 MALS is carried out by means of block 4 of the control and communication device. Information from the control computer complex 5 MPC in the block 4 of the control and communication device is received via three independent communication channels using the RS-422 interface. The input of information into the control computer complex 1 MALS is carried out via two independent Ethernet channels associated with the corresponding inputs of the MALS controllers. Information is transmitted cyclically with a frequency of 1 second. When the packet of information is received correctly, the MALS controller sends an acknowledgment signal to the block 4 of the control and communication device. On failure, when there is no handshake signal, the information packet is retransmitted. The absence of information exchange for 3 cycles in a row is perceived by the control computer complex 1 MALS as a communication failure.

Information for the station attendant, generated by the control computer complex 1 MALS and the control computer complex 5 MPC, is displayed on the information board of block 10. The display of block 10 is connected through switch 9, one input of which is connected to the control computer complex 5, and the other to the controller 11 controls. The choice of the display mode of information from the MPC or from the MPC, together with the MALS, is selected by the station attendant by pressing the appropriate button (not shown in the drawing) for controlling the switch 9.

Information about the state of the control units of floor devices of microprocessor interlocking comes from the control computer complex 5 of microprocessor interlocking to the control and communication device 4, which, via a two-channel interface of the Ethernet type and independently on each channel, transmits it to the control computer complex 1 of the shunting automatic locomotive signaling system. In the control computer complex 1, the identity of the information received from the block 4 of the control and communication device is established, and an acknowledgment signal is generated confirming the receipt of the information package. If the information received via two channels does not match, then the transmission of the message is repeated. Based on the information received, the control computer complex 1 generates information:

- about the train situation at the station, which is transmitted via the intrasystem (for MALS) Ethernet network to personal computers 12, 13 and 14 of automated workstations and to the control controller 11, as well as via a dedicated channel to a personal computer 15 of a remote workplace;

- about locomotive control commands transmitted by unit 2 equipment via a radio data transmission channel;

- data on the state of the devices of the automatic shunting locomotive signaling system, transmitted through the block 4 of the control and communication device to external dispatch control systems, bypassing the control computer complex 5.

The work on information interaction of the control computer complex 1 and the radio data transmission channel is organized cyclically. In each cycle, a broadcast telegram is transmitted, including a description of the routes of movement of locomotives, and response messages are received from locomotives with information about the parameters of movement and the location of each locomotive: actual and permissible speeds, direction of movement, coordinate of the location of the locomotive in meters to the end of the route or to the end of the section, section name, shunting group length. On the information boards of personal computers 12 -15 and the combined information board of block 10, the train situation is displayed (employment/vacancy of track circuits, the position of the arrows, traffic light indications, routes set by the station attendant and information about the current location and movement parameters of each locomotive.

User interfaces of personal computers 12-15 allow you to view the operation protocols of the system devices for a specified period of time.

Based on the data coming from the control computer complex 5 and transmitted through the block 4 of the control and communication device, the control computer complex 1 provides the formation of additional commands: permission to move a train or shunting locomotive under a prohibitory indication of traffic lights, entering a speed limit on the section included in the route, places of work on the route of movement.

The united information panel of block 8 makes it possible to control via two independent channels, the main one from the control controller 11 provides information about the train situation and locomotives, and the other from the control computer complex 5 through the switch 11 only information about the train situation.

In the MPC and MALS mode, the display of block 10, in addition to the track development and the train situation, displays the "locomotives" window with the parameters of their location and movement, as well as the state of the stop button 8.

For an emergency stop of locomotives operating in the MALS system, a button 8 with position fixation is installed at the workplace of the station attendant, connected by a physical communication channel to the control computer complex 1 MALS. When button 8 is pressed, a signal is transmitted to the input of the control computer complex 1 MALS, which leads to the formation of a control command for an emergency stop of locomotives operating at the station. The stop of locomotives registered in the MALS system is transmitted in a broadcast telegram to on-board devices via a radio data transmission channel. To cancel the stop signal for locomotives, the duty officer must release button 9. When button 9 is pressed, its image on the combined display lights up in red.

In the released state, button 9 is indicated in green.

The station duty officer from his workplace, addressed to the MPC system, organizes the work of shunting locomotives and sets their routes of movement, guided by information about the location and movement parameters of the locomotives displayed on the information board 8.

Information about the contact state of the button 9 is transmitted to the control computer complex 1 via a wired channel, which generates a command to stop the shunting locomotives included in the MALS system. The command is transmitted through the radio channel unit 2 of the equipment to the locomotive device MALS. The state of the contacts of the button 8 from the control computer complex 1 through the control controller 11 is transmitted to the combined information board of the block 10, which displays: "green" - permission to work, "red" - stop.

Diagnostic information from the control computer complex 1 through the block 4 of the control and communication device enters the external diagnostic system.

The personal computer 12 of the workstation allows the station manager to visually monitor the progress of the technological process at the station, taking into account the location, movement parameters and loading of shunting locomotives, timely correcting the actions of the station operating personnel.

The personal computer 13 allows the shunting dispatcher to optimize the shunting operation of the station, increase the efficiency of using each shunting locomotive, reduce "idle" runs and unreasonable breaks in work due to visual control of their location and traffic parameters, taking into account the current train situation at the station.

Personal computers 13, 14 and 15 allow you to view and analyze the operation of the system according to the following work protocols:

- locomotives,

- relay switching,

- radio communication.

Personal computer 12 at the workstation of the station manager of the system allows you to view:

- protocol of the station operation, which reflects the train situation and commands given by the station attendant through the channels of the MALS system;

- operating protocol for locomotives equipped with MALS on-board equipment.

The station attendant, through the automated workstation of microprocessor interlocking, gives a command to form a route for the locomotive. The implementation of this command in the MPC system is carried out by the control computer complex 5 of microprocessor centralization. At the same time, in the message structures about the state of the track development, the command data is transmitted through the block 4 of the control and communication device to the control computer complex 1 of the shunting automatic locomotive signaling system, where, according to the received data, a similar route task is formed, supplemented by data on the allowable speeds. Further, this information is transmitted through the block 2 of the equipment of the radio data transmission channel to the on-board devices of the shunting automatic locomotive signaling system for implementation. At the same time, route data is transmitted to workstations in personal computers 12-15 and is displayed on the information board of block 10 through the control controller 11.

The station device of the MALS system integrated with the MPC includes a control computer complex that provides control of the train situation based on data received from microprocessor-based interlocking devices (EC-EM systems developed by Radioavionika JSC, Automation, Communication, Informatics magazine No. 1, 2009, p. 17) via the interface, and also provides interaction with on-board equipment via a radio data transmission channel. At the same time, the integration of the workplace of the station duty officer related to the MPC and MALS is ensured.

The MALS system is built as an integrated human-machine system that operates at the pace of the technological process (real time), includes operational technological and maintenance personnel and a set of software and hardware.

System-Wide Functions:

- control of short-term loss of communication and preservation of transmitted information;

- change of operating modes of the locomotive by order of station devices;

- execution of orders of the station duty officer (DSP) for the passage of a prohibiting signal;

- identification and determination of the correspondence between the route and the locomotive;

- task, extension, shortening and cancellation of the route task;

- creation of routes for a prohibitory signal (traffic light with a prohibitory indication) from an automated workstation of a chipboard, related to microprocessor interlocking;

- control of the permissible speed of movement when performing route tasks, including at the work sites and setting them from the MPC devices;

- confirmation by the driver of the visibility of wagons on the busy track and places of work;

- measuring the length of the composition;

- determination of the distance to the places of work;

- control of the movement of the train within the last occupied section of the route task relative to its "head" and "tail";

- execution of routes outside the station with the withdrawal of the locomotive from the system;

- transmission of a command to disrupt the EPC through the radio data transmission channel to the BA MALS;

- in case of malfunctions of the locomotive equipment or its shutdown;

- in case of non-compliance with the permissible speeds of the deceleration curve;

- in case of exceeding the permissible speed of movement;

- when approaching an obstacle or a place of work, if there is no confirmation from the driver that the path is free;

- when trying to pass a prohibition signal;

- when trying to pass the last junction with the type of route "per signal" by order of station devices or chipboard.

The safety of shunting operations at the station is achieved in the system of shunting automatic locomotive signaling integrated with the MPC devices by:

- control of the train situation on the basis of data received from microprocessor interlocking devices (EC-EM system developed by Radioavionika OJSC) via the interface;

- interaction with on-board equipment via a radio data transmission channel;

- use as a combined information board of the MOC;

- organization of remote workstations of the system;

- integration of the functions of the AWS DSP MALS into the workplace of the duty officer at the MPTs station;

- use of the information board of the station attendant related to the EC-EM devices to display information from the MALS system;

- use of remote monitoring and additional jobs MALS for the head of the station and the shunting dispatcher.

In the proposed device, the technical vision subsystem is formed by digital video cameras 16,17,18,19, which are installed at all automated workstations to monitor the corresponding actions of operators to enter control commands. Each video camera with its digital data port is connected via a local network 6 of digital communication with a digital data port of the block 20 of intellectual analysis and data processing.

Block 20 interacts with the control computer complex 1 MALS and the control computer complex 5 microprocessor interlocking through the local network 6 digital communication (for example, high-speed digital communication Ethernet). The correctness of the motion control commands entered by the operators from their workplaces is determined in block 20 based on an intelligent analysis of the sequence and content of frames for each current and corresponding exemplary video script stored in the databases of the memory block 21. This applies to both train traffic control commands for ETs-EM and MALS shunting traffic control commands. For example, these can be commands for transmitting to the locomotive via a radio channel an established receiving route to the station or setting routes in the dispatcher's centralization.

In addition, block 20 can provide the formation of control commands resulting from the coordinated actions of several operators, each from their own workstation.

Block 20, in the process of machine learning of the ensemble of its internal artificial neural networks, minimizes the error functional in the process of building technological chains of dependencies between the initial information and the proposed scenarios for the actions of the operational personnel to control the movement of trains, as well as the state of the operator interface elements.

Observations made at all automated workplaces over the actions of operators on entering control commands by them through digital video cameras 16,17,18,19 allows you to increase the security of processing information used in the MPC and MALS and further automate the process of controlling train traffic through automatic transmission to locomotives through the block 2 radio channel instruments of traffic control commands.

Also, block 20 can provide control over the observance of technological discipline by operators and the formation of warnings about violations of the technological process. This makes it possible to further improve the safety of train traffic with the help of organizational measures to prevent and parry the consequences of violations of technological discipline by personnel.
