Description

The invention relates to the field of automation, communication and computer technology, and in particular to systems of operational-technological communication.

Today, the principles of construction, the structure and organization options for operational-technological communication systems are known, which are used to communicate subscribers on the stage with duty on stations that limit the stage, with dispatchers of various services, with performers of technological processes located at railway stations, as well as performers between themselves.

The closest analogue to the claimed invention by the set of essential features and functional capabilities is a system for organizing distillation communication (see Kosova V.V. Operational and technological communication of the railway department. Production and practical publication. Transport. 1993, chap. 1 , section 5).

In the well-known system, the communication of subscribers on the stage with on-duty stations limiting the stage and with dispatchers is carried out at most sites via cable lines to which intercoms (special telephone sets of the type "Stage", " Peregon-M ”,“ Peregon-KTS ”) or sockets, which, in turn, are connected to the handsets worn by the performers. Telephone sets and sockets for connecting TPS distillation communication tubes to the ASG distillation communication line are installed every 2 km. The distillation telephone line is connected to the equipment for operational technological communication (OTC) installed at neighboring stations limiting the distillation. The OTC equipment provides connection to the distillation line of the station on-call control panels (DSP). The chipboard is called when the handset of the telephone set is picked up or when the TPS tube is connected, the call goes to two station attendants at the same time and the calling subscriber calls the desired subscriber by voice. If necessary, the station duty officer calls the distillation connection to the train dispatcher, energy dispatcher, track distance dispatcher or communication dispatcher. When using TPS tubes with dialing a number, a call and connection with a chipboard or dispatcher is made when a corresponding number is dialed. When closing one of the stations and dismantling the switching equipment, the distillation line is “straightened” (the output from one station is connected to the input of another).

The disadvantages of the known distillation communication system are the low quality of communication, the inconvenience of use imposed by the limited number of intercoms and outlets for connecting the distillation communication tubes on the haul and the large distance between them, which makes it impossible to use the haul communication from the haul point remote from the connection point, making it difficult to organize large hauls at the closure of stations. In addition, the known system does not provide the ability to send a call from the station duty to a subscriber located on the stage.

The technical result consists in expanding functionality due to a differentiated approach to the number of installed cellular communication equipment, depending on the need for this type of communication on the site and the capabilities of the installed switching equipment. The invention also allows to improve the quality of the distillation communication and to provide automatic control of the integrity and condition of the lines of distillation and inter-office communication. In addition, the invention provides the ability to send a call from the station duty to a subscriber located on the stage.

This is achieved by the fact that the operational-technological communication system for the railway section contains switching stations, stations and dispatch channels, intercoms and linear sets of distillation communication, while a cellular gateway is connected to the switching station through an additional linear distillation set of communications on a section of the railway from any point of the stretch having cellular coverage.

To improve the quality of communication in the distillation section with a closed station, the system includes a distillation communication amplifier installed in a closed station and connected to the distillation lines of neighboring stations.

To control the integrity and condition of the distillation communication line, an automatic line monitoring device is included in the breakdown of the distillation and inter-station communication lines at neighboring stations of the railway section.

To make a call to the performer, located on the stage, a call distillation communication device was introduced, made with the possibility of connecting to the distillation communication line parallel to the intercom.

The drawing shows a structural diagram of a system of operational technological communication for the railway section.

The system contains switching stations 1.1-1.4, station communication channels 2, dispatch channels 3, intercoms 4.1-4.3, line kits 5 distillation communications, gateways 6.1-6.4 cellular communications, wearable cell phones 7.1-7.N, network 8 cellular , closed station 9, amplifier 10 distillation communication, device 11 for automatic line monitoring, remote control 12 on-duty station and the device 13 call distillation communication.

When organizing operational-technological communication of an inactive railway section that does not require a large number of distillation communication channels, a cellular gateway 6.1 is connected to at least one switching station 1.1 through a linear set of distillation communication 5. The contractor, located on the stage, from one of the wearable cell phones 7.1-7.N through the cellular network 8, sends a call to the gateway 6.1 cellular. The gateway 6.1 automatically recognizes the number of the calling subscriber, compares it with the numbers recorded in the availability table stored in the internal permanent memory of the gateway 6.1, and when the number matches, it takes up the line kit 5 of the distillation connection, through which the telephone operator is connected via the outhouse channels communication 2 to one of the consoles 12 on-duty stations. If the caller’s number is not in the availability table, then the gateway 6.1 does not make a call to the telephone operator and the connection is reset.

When organizing operational-technological communication of a railway section requiring a large number of distillation communication channels, the system operates as follows.

At each station of the site, switching gateways 6.1-6.4 of cellular communication are connected to switching stations 1.1-1.4 through linear sets 5 of distillation communication.

The performer, who is on the stage, from the wearable cell phone 7.1 (7.2-7.N) through the network 8 of the cellular communication directs the call to the cellular gateway connected to the switching station, with the duty of which it is necessary to establish a connection. The called cellular gateway automatically recognizes the number of the calling subscriber and compares it with the numbers recorded in the availability table stored in the internal read-only memory, and when the number matches, it takes up the line distillation kit 5 through which it is connected to the control room channels 3 or the remote control 12 station attendant. If the number of the calling subscriber is not in the availability table, then there is no connection to the dispatch channel or the station attendant console and the connection is reset.

If it is necessary to call an executor who is on a stretch with a cellular telephone, the station duty officer makes a call through the cellular communication gateway.

When organizing the distillation of a railway section on which there is a closed station, the system operates as follows.

The distillation amplifier 10 is installed at the closed station 9, and the distillation amplifier 10 is connected to the first input of the distillation amplifier 10 from the switching station 1.3, and the distillation communication amplifier 10 is connected to the second input of the distillation communication amplifier 10 from the switching station 1.4. The amplifier 10 distillation communications provides power to the connected lines necessary for the operation of intercoms and connected tubes distillation communication.

Upon receipt of a call (loopback) from the performer, who is on the stage from the intercom 4.3 between the switching station 1.3 and the closed station 9, on which the distillation amplifier 10 is installed, the latter makes the line between the closed station 9 and the switching station 1.4, broadcasting a call from contractor to the switching station 1.4. When dialing and transmitting current control signals from the executor, the distillation amplifier 10 transmits these signals to the switching station 1.4. During negotiations, the distillation amplifier 10 produces amplification with frequency correction of the transmitted speech signals.

To connect to a variety of switching equipment distillation amplifier 10 can operate in two modes:

- simplex with switching the direction of transmission by control signals transmitted by the increased loop current during the transfer of the conversation to the ASG line, and broadcasting these signals from one direction to another;

- duplex, as in a regular telephone line, but in the presence of control signals they are broadcast from one direction to another.

The system allows monitoring the lines of distillation and inter-station communication for the railway section. For this device 11, the automatic monitoring of the line of two neighboring stations is connected to the line of distillation or inter-office communication and check its integrity by transmitting from one device 11 automatic monitoring of the line to another tone signal. The lines are checked periodically without breaking the lines being checked at the moment when the line is not busy. An analysis of the busyness of the distillation communication line is carried out according to the value of the line voltage, at the same time the noise level in the line is analyzed. An increased noise level, the absence of line voltage or the duration of a session above the set threshold is perceived as an accident of the ASG line.

When organizing the distillation of the railway section using the device 13 ring distillation communication system operates as follows.

The contractor, located on the stage, connects the distillation call device 13 to the sockets located on the intercom 4.1, or the outlet for connecting the distillation communication tubes that are installed on the signaling relay cabinets (not shown). If it is necessary to call the station duty officers on the stage, from the switching station 1.1 or 1.2 from the linear set of distillation communication 5, an inductor call signal is received into the distillation line, which is received by the distillation call device 13 and converted into an acoustic signal.
