Description

The invention relates mainly to railway transport, and in particular to systems for operational-technological communication of dispatch control centers.

A well-known digital network system of railway technology telephone communication (OBTS). In accordance with the Guiding technical material on the design of the road level OBTS digital network (RTM - 3 OBTS - 2003), it is organized on the basis of standard office telephone exchanges with their installation in the road, office, branch offices and large railway stations. At the road level, QSIG and EDSS1 signaling are supported.

The system for the organization of an operational technological communication network (OTC) of the DTsUP-TsUMR (road transport control center - local work control center) in accordance with RTM - 3 OBTS - 2003 on a dial-up principle would require large financial costs associated with installing new digital switching equipment using all railway stations at the same time, a tenfold increase in the number of digital connecting lines between the separation nodes and the DCM, the development of application software for switching equipment and system telephone sets, ensuring the implementation of procedures for establishing connections in dispatch circles (light indication on OTC remotes, pedals, etc.). In addition, on the basis of standard OBTS equipment, the organization of train radio communications and distillation communications, which are mandatory for rail transport, cannot be resolved.

A well-known system of operational-technological communication (OTC) based on the protocol of information-logical interaction of digital network objects in accordance with the industry standard OST 32.145-2000 (prototype). The system provides for the implementation of digital group dispatch channels based on a ring two-level model, including rings of the lower and upper levels. The lower level rings, with a bridge station in each, are created within the boundaries of sections covering up to 50 railway stations, and the upper level rings are used to relay information between the lower level rings and pull the control circles to the road sections. Each type of dispatch communication in the rings of the lower and upper levels is assigned a separate channel interval of 64 kbit / s. The transmission of signaling and service messages is carried out in a common signaling channel (ACS), organized in the D-channel of the rings of the upper and lower levels in accordance with the OST protocol 32.145-2000.

Due to the support of a highly specialized protocol, the presence of a limited number of interfaces in the OTS digital switching equipment (which does not ensure further development of the network), the way of organizing lower-level rings covering up to 50 stations (which determine their full load and the absence of free channel intervals), this system cannot provide:

- operational-technological telephone communication and the required telecommunication services, a new vertical railroad management system ДЦУП-ЦУМР,

- the provision of operational and technological telephone communications to the administrative apparatus and dispatching personnel for the transportation of the allocated goods of the DCC with their subscribers within the boundaries of the road (region),

- the exit of the dispatching station TsUMR to their subscribers within the boundaries of linear control areas.

The problem to which the invention is directed is to organize the operational and technological telecommunications infrastructure of the new system (vertical), train traffic control and local work (DTsUP-TsUMR) for railway transport.

To solve this problem, the OTS network system was proposed, which provides communication according to group and dial-up principles to the dispatching and administrative apparatus, geographically concentrated in the DTsUP and TsUMR. The OTC segment with the group principle of organization has a two-level ring architecture based on the rings of the lower and upper levels using at least one primary digital channel (PSC) and with a separate channel interval of 64 kbit / s assigned to each type of control communication in parallel to which through digital switching stations (executive distribution - SIR, small executive - MI) at the intermediate railway junctions and points connected subscriber peripherals of operating personnel in the borders of the road. The lower level rings, with a bridge station (MS) in each, are created within the boundaries of sections covering up to 20 railway stations, and the upper level rings link the bridge stations to each other and pull the control circles to the road center. To establish connections in this segment, control and interaction signals between switching stations are used, transmitted over a common signaling channel (ACS) in accordance with the protocol according to OST 32. 145 - 2000. The control centers of control ranges (PC PU ), the digital control panels of which are used by operational dispatching personnel (train and locomotive dispatchers, traffic controllers and car distributors, respectively - DSC, TSC, DGP, DSCV). All PC launchers in the control center are interconnected with an intercom ring to unite sections organized in different rings of the lower and upper levels, but included in one control circle. According to the group principle, new types of dispatcher communications of TsUMR dispatchers (shunting and cargo) are also organized within the boundaries of linear control areas (LRU). Switching stations (CC TSUMR) with at least 12 E1 interfaces, which include the subscriber periphery of its dispatching and administrative personnel, are installed in the TsUMR. The TSUMR CSs are linked to the bridge stations of their LRU via the in-house ring central control center for transferring the TsUMR dispatchers to the lower level rings of the dispatch circles.

The second segment of the OTC system of dispatch control centers (previously not used in the network of operational and technological communications) is organized on a dial-up basis and is used for inter-dispatch communication within the centers, the exit of the road management and support services, as well as the administrative and dispatching personnel of the DCM to the administrative and dispatching personnel of TsUMR , the traffic control tower of the DCMC for the transportation of the allocated goods of cargo to its subscribers within the boundaries of the road. The architecture of the OTS switched segment at the upper level of the DCM-TsUMR is fully connected. It includes the central switching station of the road (KS MDS), which is installed in the DTSUP, connected by digital connecting lines to all switching centers of TsUMR. The CSs of the neighboring TsUMR are interconnected. The MDS CS, which includes digital consoles for road management, DCSU and providing dispatchers, plays the role of a UAC of the switched OTS network and a switching and service control node. Thanks to equipping with additional computer telephony devices (for example, a voice mail server, information and reference service) and creating a single network database for all services, the MDS CS provides a programmable, centralized logic for providing services to users of the entire road network. Inclusion of workers of linear enterprises of LRU into the switched OTS segment was carried out through existing switching stations (SIR and MI), included in the lower level rings of the OTS system with a group principle. At the same time, for the organization of digital connecting lines of the switched segment of the OTN network at the lower level, either a separate PCC or free channel intervals in existing flows with group channels are used. Thus, the switching stations of the TSUMR, SIR and small executive MI stations operate in two segments of the system - with group and with switched principles.

The OTS switched network uses the EDS S-1 signaling system (ITU-T Q.932), which supports the Intelligent Network Application Protocol (INAP), which provides departmental users with basic services and service attributes of the first set of capabilities of the CS- intelligent network 1 (Capability Sets-CSs) standardized by ITU-T Q.1211. For daily conference calls on the analysis and planning of operational work within the boundaries of landfills and linear control areas, a road-level technological audio-conference system (STAKS) is established on the basis of the meeting communications communication stations (CC SS) installed in the DCMS and TSUMR; KS SS DTSUP and TsUMR are connected by digital connecting lines among themselves. In the Local Operations Management Centers, the CS SS is linked to the TSUMR CS and SIR bridge stations using the in-house CCC. In DTSUP KS SS is linked with the COP MDS and PC PU.

The technical result of the invention lies in the fact that a network of operational-technological communication is organized, supporting group and new dial-up principles, providing communications to the dispatching operational and control apparatus, geographically concentrated in the DCM and TsUMR. At the same time, the group principle, unlike the traditional one for rail transport, provides the connection of the subscriber periphery of the control center apparatus of the control center through the administrative switching stations of control polygons (PC control centers), which were previously absent from the network, to their dispatch circles organized in the lower level rings through the central control center of the upper level rings. The lower level rings are organized within the boundaries of 20 stations (instead of the 50 stations previously installed according to OST 32.145-2000), which ensures the release of channel intervals for new types of dispatch communication (cargo and shunting dispatcher of TsUMR, etc.), communication of meetings and digital connecting lines for OTS segment, organized on a dial-up basis. Taking into account the requirements of the new control vertical, the OTS digital equipment has been modernized. Switching stations provide linking to the OTC network through 12 E1 streams. The system provides for the installation of a separate TsUMR switching station (TsUMR CS) and a meeting communication switching station (CC SS) in the Central Department Store, linking the Central Department Station with the lower-level ring bridge switching stations located at the Central Department Store, and the central control station via the in-station ring flow E1. TSUMR switching stations, SIR bridge switching stations, small executive stations of the lower level rings and part of the subscriber periphery included in them (for road management subscribers, DTsUP, road, providing dispatchers and dispatchers for selected cargo types) simultaneously operate in two segments - group and dialup. In one flow of the lower level ring, both dispatch group communications and new digital trunk lines of the switched segment are organized. One main signaling channel (ACS) supports both departmental signaling according to OST 32.145-2000 and signaling EDSS-1 of the switched network segment. The management of the road, the staff of road and supporting dispatchers are included in the central switching station of the inter-dispatch communication (CS MDS), connected via digital connecting lines to the TSUMR CS, with support for EDSS-1 signaling.

- dispatch communication for controlling the movement of trains organized through a group channel with a constantly open reception path towards the dispatcher, providing individual, group and circular calls to subscribers by the dispatcher and calls to the dispatcher by voice subscribers;

- dispatcher communication to control local work (cargo and shunting dispatchers of TsUMR), organized according to the station principle through a group channel with individual calls to the dispatcher and the dispatcher to be called by subscribers using a ringing signal;

- communication organized by a combined principle with the provision of calling some managers (dispatchers) by voice, others - by ringing signal;

- road dispatch communication for the management of the transportation of allocated cargoes within the boundaries of the road, organized using a segment of the OTS network with a switched principle.

As subscriber peripherals, digital OTC remotes can be used; direct telephone sets with a tangent that opens the transmission path of the telephone set; telephones with a dialer and with a tangent that opens the transmission path of the telephone; telephones with a dialer and with a tangent controlling the current in the line; direct telephone sets without tangents; telephones with a dialer without tangents; intermediate points of selective communication; DECT telephones.

Thus, the claimed system of operational and technological communication of dispatch control centers ensures the creation of a telecommunication infrastructure of a new vertical for the management of transportation and local work, the provision of the essential intellectual network services to the personnel of the DCM and TsUMR.
