027956 B1

The invention relates to data transmission systems and can be used to control locomotive safety devices based on digital radio communication networks in order to ensure the safety of railway transport.

A known device for checking automatic locomotive signaling UPR-ALSE TU 32 TsSh 2788-94 36983-02-00, which is installed on a locomotive or motor-car rolling stock and provides the following operating modes: automatic, in which the transmission of code signals is carried out according to a specific program, and manual, in which the transmission of code signals is carried out using the remote control or control unit (Catalog LLC SamaraPribor, 1Shr: // \ y \ y \ u.5atagarpogog.gi / 1n; cp / 1284999.1i1p1).

A disadvantage of the known device is the need to use a special inductive loop, which is either permanently mounted near the running rails on the test site, or is portable and is installed directly under the ALS coils of the locomotive safety device. At the same time, diagnostics and performance checks of the locomotive safety device are carried out only in stationary conditions.

In the context of the existing growth in traffic volumes and lengthening of the shoulders of locomotives in difficult areas up to one and a half to two thousand kilometers, the period of maintenance and serviceability of the ALS also increases, which inevitably entails an increase in the potential risk of traffic safety violations, which, in turn, is associated with a contradictory requirement set aside the locomotive for inspection in violation of the established technology of work.

A known diagnostic system for locomotive automatic locomotive signaling equipment, including serially connected control device for ALS code signal generator, ALS code signal generator, adder, receiving locomotive coils connected to ALS locomotive equipment and to the adder through a corresponding additional diagnostic winding, in addition, the system is equipped with a counter errors connected to a comparison device, one of the inputs of which is connected through a code signal generator ALS to the adder, and the other input to the locomotive equipment of ALS, as well as a control device for the noise generator connected through the noise generator to the second input of the adder, while the receiving locomotive coil contains a magnetic core with one or more main windings and an additional winding galvanically isolated from main winding or windings, for inducing in the main winding or windings an electrodynamic force equivalent to the level of electrodynamic force induced from the running rails (KN2383460C1, B61 25/00, March 10, 2010).

The known system performs diagnostics of a locomotive safety device in a depot when issuing a locomotive for a train or for another type of work to complete the trip, when the locomotive is unhooked from a train, parked or when the locomotive is on unencrypted tracks by supplying measurement signals representing a sequence of code signals to the additional winding ALS signals.

However, the known system does not allow monitoring the operability of the locomotive safety device along the train.

The technical result of the invention consists in increasing the efficiency of monitoring the operability of on-board safety devices due to the possibility of its implementation along the route of the train at the circulation site.

The technical result is achieved by the fact that the system for remote monitoring of locomotive safety devices based on digital radio communication networks contains sequentially connected locomotive radio stations control unit, a memory unit and a data processing and analysis unit, the input / output of which is connected to the output / input of a hardware software device of the workstation of the train dispatcher, and the output is to the first input of the notification unit, the identification unit, the output of which is connected it is connected to the corresponding inputs of the memory unit and the control unit of locomotive radio stations, while the outputs of the radioserver are connected respectively to the inputs of the memory unit, identification unit and control unit of locomotive radio stations, the other output of which is connected to the second input of the notification unit and the input of the radio server, hardware / software inputs / outputs the devices of the automated workstation of the train dispatcher, radio server, remote control for the station duty and base radio stations of each railway station are not connected to the network data transmission, the locomotive safety device installed on each locomotive with inputs / outputs is connected through a matching unit to the outputs / inputs of the locomotive radio station, the other input / output of which is connected to the output / input of the driver’s console, the locomotive radio stations of each train are connected via radio communication channel to the base radio stations, and a radio server, base radio stations and locomotive radio stations are configured to organize radio communications based on the standard ΌΜΚ

The essence of the proposal is illustrated in the drawing, which shows a structural diagram of one of the embodiments of the proposed system for remote monitoring of locomotive safety devices based on digital radio networks.

System for remote monitoring of locomotive safety devices based on digital

- 1 027956 radio communication network contains installed in the dispatch center 1 in series connected block 2 control locomotive radio stations, block 3 memory and block 4 processing and data analysis, the input / output of which is connected to the output / input of the hardware-software device of the workstation 5 train dispatcher, and the output is to the first input of the notification unit 6, an identification unit 7, the output of which is connected to the corresponding inputs of the memory unit 3 and the control unit 2 of locomotive radio stations.

The outputs of the radioserver 8 are connected respectively to the inputs of the memory unit 3, the identification unit 7, and the locomotive radio station control unit 2, the other output of which is connected to the second input of the notification unit 6 and the radioserver input 8. The inputs / outputs of the hardware-software device of the workstation 5 of the train the dispatcher, the radioserver 8, the console 9 of the station duty officer and the base radios 10 of each railway station 11 are connected to a data transmission network 12 made, for example, in the form of a network ΙΡ.

The locomotive safety device 14 installed on each locomotive 13 of the train is connected via inputs / outputs block 15 to the outputs / inputs of the locomotive radio station 16, the other input / output of which is connected to the output / input of the driver's console 17. Locomotive radio stations 16 of each train are arranged to organize a radio communication channel with base radio stations 10.

The radioserver 8, the base radios 10 and locomotive radios 16 are configured to organize radio communications based on the стандарта standard.

As a locomotive safety device 14, a safe locomotive integrated BLOCK complex is used (Shukhina E.E. Locomotive safety systems // Automation, Communications, Informatics, 2013, No. 2, pp. 2-3).

The proposed system for remote monitoring of locomotive safety devices based on digital radio communication networks operates as follows.

In automatic mode, the hardware-software device AWP 5 of the DSC periodically sends a request to the locomotive station 15 of the locomotive 13 of each train moving in the circulation section for information about the operation of its locomotive safety devices 14 and the location of the train. The radioserver 8 provides the organization of the communication channel between the hardware-software device AWP 5 of the DC and the locomotive radio station 16 of the locomotive 13.

The locomotive radio station 16 sends the request through the matching unit 15 to the safety device 14. In response to the request, the security device 14 transmits the data recorded on the registration cassette of the security device 14 at a given time to the locomotive radio 16. On the registration cassette of the locomotive safety device 14, information about the parameters of the train’s movement and operation is recorded in automatic mode safety devices 14, including the current coordinates of the location of the train.

As a locomotive radio station 16, a locomotive radio station of a standard стандарта digital radio communication system is used, which provides operation on two frequency slots on a single frequency channel. In this case, according to the first time slot, the radio station 16 generates a data packet that includes information about the individual number of the locomotive 13 and / or voice information, and according to the second time slot, a data packet that includes information about the current location coordinate of the locomotive 13, train motion parameters and the operation of the locomotive safety device 14.

Radio station 16 in real time monitors its status (operational / malfunctioning). Information about the results of the monitoring radio station 16 uses in the formation of one of the time slots.

Information from the locomotive radio station 16 of the train at the circulation site is received by one base 10 station in the coverage area of which the train is located, and is transmitted via the data transmission network 12 to the input of the radio server 8 of the train radio communication.

According to the results of processing the obtained data, the radioserver 8 sends information about the individual numbers of the radio station 16 and locomotive 13 of each train to the identification unit 7, data on the status of the locomotive radio station 16 and data on the current location coordinate of the locomotive 13 to the control unit 2 of locomotive radio stations, information on the identification number locomotive 13, the current coordinate of its location and data on the parameters of the movement of the train and the operation of the locomotive safety device 12 - in block 3 of the memory.

The memory of the identification unit 7 stores information about the individual numbers of the radio stations 16 and locomotives 13 located in the circulation area. If the individual number of locomotive 13 coincides with one of the numbers in the specified list of locomotives, block 7 identifies the individual number of locomotive 13 and transmits information about it to memory unit 3 and to health control unit 2 of the locomotive radio station, identifies the number of radio station 16 in the same way and transmits information about it unit 2 health monitoring locomotive radio station.

Block 3 stores information about the current coordinate of the locomotive 13 of the train participating in the workflow at the treatment site, data on the parameters of its movement and the operation of the locomotive safety device 14, under the individual locomotive number 13. Similarly, in block 2 for each locomotive 13 of the train, status data his radio stations 16 are identified

- 2 027956 for each locomotive 13 of the train, data on the state of its radio station 16 are identified by the individual number of the radio station of locomotive 13.

If the locomotive radio station 16 is in good condition, the locomotive station control unit 2 sends a control signal to unit 3 to enable the transmission of information about the parameters of the train participating in the workflow at the treatment site, data on the operation of its locomotive safety device 14 to the data processing and analysis unit 4.

In case of a malfunction of locomotive radio station 16 of locomotive 13, block 2 sends the corresponding information indicating the number of locomotive 13 and the current coordinates of its location to the radio server 8. Radioserver 8 transmits the received information about the malfunction of the locomotive radio station 12 to the console 8 of the duty station closest to the location of the train at a given time .

In addition, to notify the train dispatcher of a detected failure, unit 2 sends information about the malfunction of the train radio station 16 to the notification unit 6, on which the light indicator lights up and the identification number of the locomotive 13 with the faulty radio station 16 is displayed.

Informing the train dispatcher and the person on duty at the station closest to the current location of the train from the inoperative locomotive radio station 16 of the train allows you to quickly take measures to replace it.

Upon receipt from block 3 of information about the parameters of the movement of the train participating in the workflow at the training ground, and data on the operation of its locomotive safety device 14, block 4 carries out its processing and analysis. If block 4 detects an error in the transmitted information or in the absence of information from the locomotive safety device 14, it generates a corresponding signal characterizing the malfunction of the locomotive train safety device 14 and sends it to the notification unit 6 and to the hardware-software device AWP 5 of the DCC to inform the train dispatcher the presence at the landfill of locomotive 13 with a faulty safety device 14. Upon receipt of data about the malfunction of the safety device 14 of the locomotive 13, the hardware-software device AWP 5 of the DSC automatically notifies train drivers and station attendants of the presence of a train with a faulty locomotive safety device 12. On the information board of the notification unit 6, the indicator light lights up and the identification number of the locomotive 13 with the faulty locomotive safety device 14 is displayed.

At the same time, the train dispatcher, having received this information, depending on the train situation at the landfill, may decide to follow the train with the locomotive safety device 14 turned off or to replace it at the nearest station. For this, it sends a corresponding voice message to the train locomotive driver 13 and the duty officer at the station closest to the location of the train at a given time through the hardware and software device AWP 5 DCC through the communication channel.

Thus, the proposed invention in an on-line mode monitors the operability of locomotive train safety devices 14 along the train, which ensures the safety of train traffic at the treatment ground.
