Description

Switching station for operational technical communications network.

The utility model relates to telecommunication technology, is intended for the organization of operational-technological communication, mainly of railways in analog, digital and digital-analog networks, in particular, to operate as an administrative station for separate operational-technological wire communication (OTC) and simplex train radio communications, as well as an executive station of departmental wire communication, which is both a commutator of a station operational and technological communication and a two-way park with ides.

The territorial group radio communication system is known, consisting of local systems with mobile subscribers and base stations using radio path controllers, a switch for connecting base stations to a public network and transmitting information from base stations stored in memory, which ensures the availability of data on the location or cost of mobile subscribers coming from the controllers of the respective base stations (see, for example, the description of the invention to the patent of the Russian Federation No. 2138916, CL H 04 J 3/00, publ. 1999).

The disadvantage of the system is the distortion of transmitted messages from mobile subscribers located on one straight line.

The closest known for its technical nature and the achieved result is selected as a prototype is a switching station for a network of operational-technical communication, containing a basic module with external and internal communication channels for transmitting information (see book edited by V.M. Volkov Automatic telephone communication in railway transport, Moscow, Transport, 1996, pp. 79-82).

The disadvantage of this device is its inefficiency due to the presence of inefficiently used additional expensive equipment.

The essence of the claimed utility model is expressed in the aggregate of essential features sufficient to achieve the technical result provided by the proposed utility model, expressed in the expansion of technological capabilities through the independent transmission of information both inside the station and to the external network while improving reliability and information content.

The claimed combination of essential features is in direct causal relationship to the achieved result.

Comparison of the claimed technical solution with the prototype made it possible to establish compliance with its criterion of novelty, since it is not known from the prior art.

The proposed device is industrially applicable, since it can be implemented by existing technical means.

Thus, the proposed technical solution meets the established conditions of patentability of a utility model.

The other known technical solutions for a similar purpose with similar significant features by the applicant was not found.

The drawing shows a block diagram of a switching station.

The inventive device is a station with intercoms and call panels and interface devices with analog and digital communication lines.

Intercom and call panels (hereinafter referred to as PR managers' consoles) are connected to the switching station via a digital channel 2B + D.

The station’s equipment uses a modular construction principle, which allows you to select a subscriber capacity for specific objects.

synchronization module 1 (C), which provides the generation of clock signals and controls the remaining modules,

switching module 2 (ЗЕ1), designed for interfacing with three primary digital channels (PCC), forming group channels of supervisory communication and train radio communication, as well as for train radio communication, data transmission, etc .;

distillation and inter-station communication module 3 (LK-PMS), designed to connect a two-wire analog inter-station communication line, as well as to receive ringing signals from the distillation communication tube;

two-way park communication module 4 (2LK-DPS) having a two-wire termination designed to connect the input of the feeder amplifier and the output of the park intercom line, as well as a two-wire termination designed to receive signals from the park intercoms;

module 5 of linear sets of digital telephones (8LK-TsT), providing connection via digital channels 2B + D to eight remote controllers (PR) with access to dispatch communication channels;

module 6 of linear sets of selective communication (6LK-IS), designed to connect up to six four-wire analog lines of selective dispatch communication. Each of the six linear sets of selective communications is designed to operate both in the mode of generating signals for selective (group circular) calls, signals for selectively connecting radio stations, calling drivers on duty at stations, controlling radio stations and hanging up, and in the mode of receiving selective calls, connection control signals radio stations, blocking signal (call);

a module of 7 linear sets of direct phones (16LK-PT), designed to connect up to 16 direct phones via analog lines;

module 8 linear data transmission kits (2LK-PD),

module 9 of the linear set of train radio communications (LK-PRS),

a module of 10 linear sets of four-wire terminations (4LK-ТЧ), designed to generate and receive signals of direct (PU) and reverse (OS) control of half-duplex mode of negotiations and on / off adders;

modules 11 power supply 48 V (weighted), power supply 12 (± 48 V) and 13 (± 5 V).

Depending on the purpose of the station, the number and purpose of installed modules may be different.

The work of the regulatory station is as follows.

On the remote control of the head (dispatcher), after pressing one of the calling buttons, a call is made via digital channel D to module 8LK-CT, which, in the case of a network, is transmitted to module ZE1 and through a separate communication channel (ACS) of the external network of the lower level ring, connecting up to 30 stations (not shown conditionally) are transmitted to the subscriber of the recipient. The format of the call command is as follows: call command sender address-receiver address-text. The recipient of the ring station recognizes its address on the ZE1 module and sends the received message to the 8LK-CT module, which sends a call to the receiver's console, for example, the station duty officer.

Upon receipt of a call at the executive station, the 8LK-CT module generates a call confirmation command and sends it along the route of the call command in the reverse order to the receiver module ZE1, which then sends it to the management station. Upon receipt of a call confirmation, it goes through a similar

the chain at the distribution station: module ZE1 - module 8LK-CT - the dispatcher (manager) remote control, which displays the corresponding confirmation that the given communication channel is working and the call has been received by the recipient, and upon receipt of confirmation one of the following object states is displayed on the control panel :

a) the norm

b) equipment malfunction c) busy

d) the absence in the subscriber station with the recipient address number.

The format of the call confirmation command is as follows: sender-address-recipient-recipient address-text confirmation command.

In case of malfunction of the recipient’s equipment, employment or absence at the subscriber station with the recipient’s address number, a corresponding message will appear on the dispatcher’s console.

In the event of a channel malfunction, for example, when a fiber-optic communication line is broken, the call control signal will not come, and a corresponding message will appear at the automated workstation of the on-duty electrician.

The format of the messages Call and Confirmation of a call inside the station for local communication is similar to the network one, except that the transmitted signals are not transmitted to the ZE1 module, but are directly transmitted inside the station between various objects, for example, 8Zh-TsT, 16LK-PT, etc.

Due to the presence of a digital switch in each module and the use of a digital CAN interface (Controller Area Network) inside the station, parallel operation is possible when making simultaneous calls that are not currently interconnected between several station objects independently, for example, from one module 8LK-CT a subscriber’s network call is made, and

another 8LK-CT module makes a local call regardless of the network connection, calling, for example, a direct subscriber through the 16LK-CT module.

The proposed switching station allows for the communication of subscribers without the use of automatic telephone exchanges and group equipment. 6
