Utility Model Implementation

Figure 1 presents the structural diagram of the proposed dispatch system for centralization of train control. The system includes redundant gateways / servers 2, 3 connected by an isolated local area network (LAN) 1, connected to both the LAN and corporate network 4, communication stations 5, 6 connected to the LAN, and via communication channels 7 and 8 with controlled control points (KP) 10, 11 and 12, and the redundant automated workstations of the dispatcher (AWS DNTs) 13 and 14 connected to LAN 1 and to the responsible command confirmation device (UPC) 15, controlled by the train dispatcher, as well as AWP electromechanics - remote 16, functioning through a corporate set 4 and the local 17 connected to the LAN. KP 10, 11 and 12 are connected via communication channels 7 and 8 to each other and to communication stations 5, 6, and are also connected to information display devices 18, 19 and 20 and secure keys (BC) 21, 22 and 23, part of the outputs which is connected to devices of electrical centralization, microprocessor centralization and relay-processor centralization (EC / MPC / ROC) 24, 25 and 26 through relay comparison units 27, 28 and 29, also called relay blocks for the implementation of critical teams, and the other directly.

Thus, the dispatch centralization system (dispatch centralization - DC) is a two-level dispatch control system for train traffic. The upper level of the system includes a redundant workstation for a train dispatcher and equipment for a DC station, connected by an isolated local area network (LAN DC), as well as automated workplaces of an electrician - a remote AWS SHN operating through a corporate SPD network and a local one operating through a LAN DC. Additional equipment of the upper level consists of a device for confirming responsible UPC commands, made with the possibility of controlling a train dispatcher and functionally interacting with the main and backup sets of AWS DSC. The lower level of the system includes the equipment of controlled control points (KP) and additional equipment installed at the stations of the control room. Additional equipment of the lower level includes a secure key (BK), a display device (UO) and a relay block for the implementation of critical teams (BROK).

Information is exchanged between the upper and lower levels of the system via redundant digital channels, physical lines of the trunk cable or dedicated channels of the tonal frequency.

AWS DNTs, designed specifically for monitoring and controlling the transportation process by the train dispatcher, operating in the LAN network of the DC, displays information about the status of control objects and enter telecontrol commands (TU).

The DC post, using the redundant equipment of the communication stations, implements information exchange of the DSC AWP with the KP stations distributed, and using dedicated redundant gateway computers (gateway servers) provides information interaction with other information management systems in the corporate data transmission network.

The reserved automated workstation of the electromechanics AWP SHN is used to perform diagnostic and service functions.

The responsible command confirmation device (UOC) is intended to confirm the correct implementation of the transmission of critical telecontrol commands.

The workstation equipment of the DSC includes a rack with redundant industrial computers, high-resolution monitors, a keyboard, and a mouse. The rack is equipped with uninterruptible power supplies, LAN equipment, patch panels.

Equipment of the DC central office: communication station — a redundant industrial computer equipped with modem equipment and a LAN adapter DC; a gateway / server — a redundant industrial server equipped with two network adapters for interfacing with a LAN DC and SPD, on which the DC gateway software components operate, providing interaction with external systems through SPD.

The device of the control point KP is designed to perform the functions of the system in relation to the EC / MPC / ROC devices (electrical centralization / microprocessor centralization / relay-processor centralization) of a specific station in the dispatch area, for receiving telecommand commands and responsible telecommand commands intended for this station, their implementation in compliance with the Binding Map, as well as the collection and sending of information about the status of control objects to the workstation of the DSC. The number of transmissions is determined by the number of stations. The control unit includes a microprocessor unit, a display unit, a telemechanics unit - the number is determined by the number of control and monitoring objects, as well as an input and switching module.

The general functioning algorithm of the centralized dispatching control system includes a telecontrol algorithm and a telecontrol algorithm that implement its two main functions. The implementation of the control algorithm is necessary to provide the dispatcher with information of an informational and signaling nature, necessary for making decisions on managing the transportation process, as well as for visualizing information about the train situation, state and operating modes of the control objects - signaling, centralization and blocking devices, the schedule of the executed movement and the performance of the dispatcher in a visual and convenient form.

The telecontrol algorithm is implemented as follows. Controlled control points (KP) 10, 11 and 12, distributed over the stations of the dispatch area, perform a continuous cyclic interrogation of the status of discrete control objects. The communication station 5 or 6, in turn, carries out a cyclic interrogation of all control rooms 10, 11 and 12 of the dispatch area, receiving from them information about the status of all control objects, optimally using the available communication channels 7 and 8. Then the communication station is via a local area network ( LAN) transmits information about the state of the monitoring objects to the workstation of the DSC, which carries out logical signal processing. AWS DNTs is a server of operational information for software systems that provide visualization of information, plotting the movement, keeping a protocol, etc.

Telecontrol functions, including input, analysis, processing and execution of a comprehensive set of telecontrol commands by arrows and signals of separate control points, are implemented as follows. Telecontrol commands (TU) generated by the train dispatcher to AWS DNTs 13, 14 are transmitted through the LAN of the DC to the communication station 5, 6. The communication station 5, 6, if there is a TU command for any control unit 10, 11 or 12, interrupts the cyclic interrogation and sends the command out of turn, after which the polling resumes. The controlled point KP 10, 11 or 12, which accepted the TU command, transmits it to the devices it controls through the BK 21, 22 or 23 secure key, which allows only the permitted type of the actuator relay trigger signal to pass, either directly or, in the case of transmission of responsible commands through devices BROK 27, 28 or 29. The adopted scheme for the implementation of responsible teams using the relay comparison unit (BROK) 27, 28 or 29, involves the transfer and control of preliminary and executive commands TU. The implementation procedure begins with the implementation of preparatory actions: sending and monitoring the execution of the preliminary command to the workstation of the DSC. The input of any preliminary command is confirmed by a single confirmation command, which is implemented in two-channel mode through duplicated outputs using the relay block comparison BROK. Confirmation is made by the train dispatcher using the UTOC device.

To quickly display all the diagnostic information about the state of a functioning hardware-software complex, display devices (UO) 18, 19 and 20 are additionally installed.

Compared with the prototype, in this utility model, through the use of an economical BROK device in the relay part of the OTU command implementation path, for a standard station, for example, with the implementation of 16 critical commands, the number of installed relay equipment is halved (33 type H relays, 3 relays NMSh type and 4 KBMSh blocks). The increase in the number of teams is possible by remote mounting from the calculation of 2 type H relays per command.

To exclude spontaneous activation of the executive relays, in the paths of the lower-level telecontrol commands, devices are additionally installed - safe BC keys, which allow the permitted type of signal to run the executive relay. This is ensured by double conversion of input pulse signals - circuit differentiation and integration. If either of these two laws of signal conversion is violated, the output of the circuit either does not have voltage, or it is an order of magnitude less than that necessary to turn on the executive relay. The use of BC in the telecontrol command implementation schemes improves their safety parameters.

In order to be able to quickly display all the diagnostic information about the state of the software and hardware complex of the system, as well as the state of the control object, UO display devices based on the local LCD panel are additionally installed on all linear points of the dispatch section. This allows you to increase the information content, expand the functionality, significantly improve the setup and maintenance of the system, which is another factor in improving the manufacturability of the system.
