Description

The invention relates to techniques for radio communications, in particular to systems for technological digital radio communications, and may find application in technological processes at railway stations.

A well-known MotoTRBO system developed by Motorola with the addition of the Neocom TRBOnet Enterprise dispatch console with a radio server, to which Motorola MotoTRBO stationary digital radio station is connected via a radio channel for communication with mobile subscribers. When the power is turned on, the MotoTRBO subscriber digital radio station sends an authorization request to the radioserver and registers in the TRBOnet network. For registered subscribers in the TRBOnet network, the dispatcher becomes available to the system’s main functions - individual and group calls, text messaging, use of the built-in telemetry of digital radio stations MotoTRBO, GPS monitoring of subscribers, recording of conversations (www.http: //shockufa.ru/motorola/podtrbo .htr, file update 10/14/2011)

A drawback of the MotoTRBO system developed by Motorola is that it lacks the ability to exchange information between all participants in the technological processes of managing the operation of the sorting station, including voice and command information, when performing critical operations.

The closest technical solution is a device for transmitting information when shunting at a railway station, containing radio complexes of locomotive drivers, train compilers and station duty personnel, each of the radio complexes of locomotive drivers includes a transceiver associated with communication channel busy control units. The radio complex of locomotive drivers is additionally equipped with control units for the transceiver operating mode, emergency message allocation, synchronization and an interrupt pulse generator.

This device allows you to send emergency messages out of turn, putting at this time the work of the transceivers of other subscribers in receive mode, which provides additional protection against mutual interference (RU 2179518, 05.20.2001).

However, the device does not have the ability to simultaneously transmit packet data and voice messages, the functions of monitoring the location and condition of the train compiler and transmitting this information to the locomotive driver, shunting dispatcher, station duty, other persons controlling his work, which is necessary to improve the safety of train compilers and timely making management decisions.

The problem to which the invention is directed is to create a radio control system for the work of train compilers at a railway station, which, when performing technological operations to form and disband trains, controls the safe location of each train compiler relative to rolling stock cars.

The technical result consists in increasing the effectiveness of control over the radio channel of the work of the train compiler by providing, when performing technological operations to form and disband trains at the railway station, operational control over the safe location of the train compiler relative to the rolling stock cars.

The technical result is achieved by the fact that the system for monitoring the work of the train compiler via the radio channel at the railway station contains on-board radios and a wearable radio station of the train compiler installed on the shunting locomotives, the radioserver and repeaters installed at the station, the inputs / outputs of which are connected to the IP network, to which are also connected the inputs / outputs of the hardware and software devices of the automated workstations of the station duty officer and the radio communication electrician, as well as the processing unit and the distance sensor, installed in a separate case attached to the case of the wearer’s wearable radio station, while the measuring element of the distance sensor is placed on the outside of the case with the possibility of movement in horizontal and vertical planes, and the output of the distance sensor through the processing unit is connected to the input of the transceiver of the wearable radio station of the train compiler, a transceiver the on-board radio station of each shunting locomotive is connected to the outputs / inputs of the intercom the radio server, repeaters, a transceiver of a locomotive radio station and a transceiver of a portable radio station are configured to organize a radio communication system based on the DMR standard.

The wearable radio of the train compiler includes a “man down” mode operating unit, the output of which is connected to another input of the transceiver.

The radioserver contains random access memory for recording, storage and playback of conversations between compilers, shunting locomotive drivers and station duty, as well as control decisions and events.

The essence of the proposed technical solution is illustrated by the drawing, which shows a structural diagram of an embodiment of a system for monitoring the work of a train compiler over a radio channel at a railway station.

The system for monitoring the work of the train compiler over the radio channel at the railway station contains 1 on-board radios 2 and a wearable radio station 3 train compilers installed on the shunting locomotives, installed at station 4 a radio server 5 and repeaters 6, the inputs / outputs of which are connected to the IP network 7 to which are connected also the inputs / outputs of the hardware and software devices of workstations 8 and 9 (AWP 8 chipboard and AWP 9 ШН) of the station duty officer and radio electrician, distance sensor 10 installed with the entered unit 11 processing in a separate housing 12 attached to the housing of the wearable radio station 3, while the measuring element of the distance sensor 10 is placed on the outside of the housing 12 with the possibility of movement in horizontal and vertical planes, and the output of the distance sensor 10 through the processing unit 11 is connected to the input of the wearable transceiver 13 radio stations 3 of the train composer, transceiver 14 of the on-board radio station of each shunting locomotive 1 inputs / outputs connected to the outputs / inputs of the intercom panel 15 ma Iniesta and radioserver 5, 6 repeaters, transceiver 14 locomotive station 2 and the radio transceiver 13 of a wearable 3 made with the possibility of radio communication systems based on DMR standard.

The communication of the on-board radio station 2 of the shunting locomotive 1 with the wearable radio station 3 of the originator, working with the driver of the shunting locomotive 1 in pair, is carried out through a digital radio channel through a repeater 7, in the coverage area of which are the shunting locomotive 1 and the wearable radio station 5.

The communication of AWP 8 DSP and AWP 9 SHN with on-board radios 2 shunting locomotives 1 and wearable radio stations 3 originators is carried out via a digital radio channel in the dual-frequency simplex mode via a radio server 5 and repeater 6, in the coverage area of which are shunting locomotive 1 and wearable radio station 5. Number of repeaters 6 are selected taking into account the coverage area of the station.

The wearable radio station 3 of the train compiler includes a unit 14 for the operation of the "man down" mode, the output connected to another input of the transceiver 13.

Wearable radio station 3 is equipped with a means for placing it on the clothes of the originator in an upright position.

Radioserver 5 includes RAM for recording, storing and playing back conversations between compilers, shunting locomotive drivers and station duty, as well as control decisions and events.

One of the most important conditions for safe operation at the marshalling yard is the correct and strictly regulated execution of maneuvers associated with the formation and disbandment of trains. This work requires constant monitoring of the shunting locomotive driver over the progress of the work of the train compiler working with him in pairs, an accurate knowledge of his position relative to the rolling stock cars. It is especially important to monitor the work and condition of the compiler in the conditions of his work with wagons with dangerous goods, when the car is pushed and uncoupled by the compiler.

Under these conditions, the high quality of data transmission and voice communication between workers ensuring the execution of the process is crucial for controlling the shunting operations at the station. To do this, in the proposed system, the reception and transmission of information via a digital radio channel is organized according to the DMR standard, which allows to ensure high quality of voice information and data transmission during technological processes.

Using the IP 7 network in the proposed system allows the transmission of data and voice signals in real time. The IP 7 network uses a protocol based on multicast, according to which the call received from the subscriber is transferred to all devices of the IP 7 network.

Radioserver 5 receives 100% of the traffic (voice, data and control) for processing and routing calls from on-board radios 2 and wearable 3rd radios, as well as from subscribers of the IP 7 network - AWP 8 chipboard, AWP 9 SN and repeaters 6. In addition , the radioserver 5 carries out continuous monitoring of all network devices with the transfer of information to the hardware-software device AWP 9 ШН on duty to an electrician. Additionally, the radio server 5 provides control of the radio signal levels of the actual state of the spatial radio coverage of the network.

The system operates as follows.

When performing work, the train compiler includes, mounted on the compiler in a vertical position, a radio station 5 and a distance sensor 10.

The distance sensor 10 due to the sequential movement of the measuring element scans the distance to the obstacle both in the vertical plane and in the horizontal. When performing shunting operations of a train compiler paired with a shunting locomotive driver, an obstacle is a moving train. According to the results of experimental studies, the value of the minimum distance of the location of the compiler from the rolling stock, ensuring its safety, is set to 1 m.

The measurement results from the output of the sensor 10 are sent to the processing unit 11. The processing unit 11 compares each measured distance value with a predetermined value characterizing the safe distance of the originator from the moving train.

If the readings of the measurement sensor 10 are less than the specified value, the unit 11 generates an alarm signal and sends it to the input of the transceiver 13.

Having received such a signal, the transceiver 13 transmits an alarm message over the radio channel through the repeater 6, in the area of which it is located, to the transceiver 14 of the shunting locomotive 1, with the driver of which the originator of the wearable radio station 3 is paired.

In addition, when the radio station 5 is tilted more than a predetermined value of degrees relative to the operating position, the “man down” mode functioning unit 14 generates an alarm signal for a certain time, and when the position is maintained for a longer time, an “alarm” signal. In this case, the transceiver 13 also transmits an alarm message, which likewise arrives at the intercom-remote control 15 of the driver.

The set value of the degrees of the angle of inclination is set when tuning the radio station taking into account the planned work of the compiler.

The transceiver 14 of the locomotive radio station 2 converts the alarm message into an “alarm” signal and sends it to the intercom-call station 15 of the driver. The intercom-call panel 15 reproduces it in the corresponding optical signal.

In this case, the driver stops the train and calls the train compiler about the nature of the work he performs on the call station 4, following the results of the negotiations, takes appropriate measures on the nature of the shunting and ensuring the safe operation of the compiler.

In addition, the repeaters 6 send an alarm message over the IP network 7 to the radio server 5. The radio server 5 processes the received data and sends it to the hardware-software device AWP 8 chipboard.

The station attendant monitors the technological operations at the station, including the work of train compilers. Upon receipt of an alarm message from the compiler’s wearable radio station 3, the station duty officer for radio communications or the speakerphone system existing at the station, depending on the situation at the station, can give commands to stop the moving train along a nearby path, as well as notify workers located at the station’s territory about the current situation.

The on-duty electrician monitors the operability of the radio communication system and, if necessary, ensures the prompt replacement of failed wearable and locomotive radio stations.

Thus, the proposed control system of the train compiler’s work on the radio channel at the railway station due to the operational control of the safe location of the compilers relative to the rolling stock cars when coupling or uncoupling the cars ensures the safety of the compilers and the efficiency of shunting at the railway station.
