Description

The invention relates to communication technology, in particular to technological radio communication systems in railway transport, and can be used to monitor the status of locomotive radio stations in operation both along the locomotive and during technical inspections and maintenance in a locomotive depot.

A known monitoring system for locomotive radio stations of a digital radio communication system, comprising a radio station status monitoring unit, a train / locomotive number setting unit, a channel monitoring unit, a transceiver connected via radio channel to base stations connected to a switching center of a digital radio communication system to which a server is connected network management, service message server connected to the input with the switching center, and the output to the data network of a unified monitoring system and Administration (ECMA) (RU 2407243 C1, H04W 64/00, 12.20.2010).

The locomotive radio station additionally includes a satellite positioning unit, a control controller for the mutual exchange of information with the radio station status monitoring unit, the train / locomotive number setting unit, the channel monitoring unit.

The system provides control and video surveillance on the ECMA monitor screen of the technical condition of locomotive radio stations with the indication of specific faulty units.

However, the known system does not provide for monitoring locomotive radio stations and evaluating their basic parameters with certified devices.

The closest analogue is the monitoring system of analog locomotive radio stations (S.V. Filippov, “Monitoring of locomotive radio stations”, J. “Automation, Communications, Computer Science”, No. 3, 2013, from 45-48). The known system checks the status of radio stations along the traction rolling stock at automatic control points (AKP). Each automatic gearbox includes a computer with a testing program, stationary radio stations for train radio communications of the hectometer (GMV) and meter (MB) ranges, and the interface device. Automatic transmissions are connected via a data network to the IntraNet data network of the railway.

The monitoring system allows you to:

- determine the range of radio communication with the locomotive in the path of its movement to transmit and receive information;

- evaluate the frequency deviation of locomotive radio stations;

- detect failures of radio stations along the route of locomotives;

- identify cases of entering in the schedule of the executed movement of the wrong side numbers of the locomotive;

- use the monitoring results to analyze and determine the status of radio stations in controversial situations.

In the well-known system, the monitoring results are transmitted to the automated system "Radio communication AS", which, when a technical device detects a malfunction, automatically sends electronic messages to the monitoring duty.

However, in the known system, the operability of locomotive radio stations along the route is determined by the signal level at the output of the stationary radio station by non-certified devices, and depending on the location of the train on the site without specifying the state of the blocks of locomotive radio stations. Moreover, if communication is provided with distant block sections, the state of the radio station is recognized as excellent and good, with neighbors - satisfactory and unsatisfactory. If the connection is established only within the station - bad. Such an assessment does not allow to clearly establish the condition of the locomotive radio station and to quickly determine the specific damage to its nodes and blocks.

In addition, when confirming the malfunction, the monitoring duty officers notify train dispatchers and station duty officers along the train route, after which measures are taken to unhook the locomotive and check the locomotive radio station at the checkpoint. All this slows down the process of restoring the operability of locomotive radio stations and, ultimately, increases the duration of the transportation process.

The task to which the invention is directed is to create an automated control system (ASK) of the technical condition of analog locomotive radio stations along the route and during pre-trip monitoring in a locomotive depot, which collects complete data about the monitoring object through interaction with information management systems in a road traffic control center; measuring parameters of locomotive radio stations during data transmission from a locomotive with certified devices; measurement of interference, direction finding of radio equipment in the frequency ranges reserved for railway transport by certified devices, operational monitoring of information about the condition of a locomotive radio station in the AWM-ax of a road and regional communication center, and transmission of data on failure to monitoring and administration facilities of the ECMA.

The technical result consists in increasing the efficiency of monitoring the status of analog locomotive radio stations, reducing its cost due to the centralization of monitoring the technical condition.

Server 2 with the help of server 1 for real-time data processing interacts informationally with the information resources of server 21 of the IMS AS, which interacts with the Ural State Institute, APK-DK, Setun DC, YuG DC, etc., to obtain information about the location of the rolling stock in various sections of the road. In addition, the server 2 through the data transfer network 17 interacts with the AS ES server 18 to receive data on radio facilities on locomotives and rolling stock circulating in different sections of the railway, with the ECMA server 19 for prompt transmission of up-to-date information on the operability of monitored locomotive radio stations 11 and statistics of completed checks.

Server 2 initiates verification of locomotive radio stations by transmitting over the IP network 10 control commands AKP-D 5 and AKP-S 6.

The hardware-software device AWP 4 of the duty center for road control conducts the processing of information received from IKSP 7 for the analysis of signals and interference and presents it in a separate screen form.

An automated system for monitoring the technical condition of locomotive radio stations operates as follows.

When monitoring the status of the locomotive radio station along the route, the data processing server 1 once every 20 seconds sends a request to the server 21 of the IMS IC about the location of the rolling stock (approaching, approaching or arriving) on the sections of the railroads on which check locomotive radio stations. Server 1 processes the received information and sends it to server 2.

Server 2 transmits data on the rolling stock number via data transmission network 17 to AS ES server 18, and sends the data on the location of the rolling stock locomotive to driver 3.

The AC 18 EP server includes a database of electronic passports (EP) of locomotives, which reflects the main technical and operational characteristics, information about the completeness, technical condition, place of operation, repairs, both the locomotive and its certified equipment (Regulations for working with automated system "Locomotive Electronic Passport", part 2, dated January 20, 2012 N 75р, http://jd-doc.ru/2012/yanvar2012/2335-ot-20-yanvarya-2012-gn-75r2). In response to the request, the AS 18 EP server sends him the electronic passport data of the locomotive radio station installed on board the locomotive of the rolling stock. The electronic passport of the locomotive station contains, inter alia, the on-board number of the locomotive and the registration depot, the date the radio station was installed, and the type of radio station.

Server 2 processes the data from the server AS 18 ES and sends them to the shaper 3.

By the location of the locomotive, server 2 determines the number of the AKP-S 6 closest to the locomotive, generates control commands to enable its testing program, depending on the type of locomotive radio station, which transmits via IP network 10 to the input of its system unit 9.

The AKP-S6 system unit 9, having received a test command, generates the “TEST 2” ** or “TEST 3” *** signal codes similar to the signal codes used in the well-known STOR-1MK control device, designed for operational pre-trip remote control of locomotive radio stations (Control device for locomotive radio stations STOR-1MK, YaUISH.464424.002-24TU, http://www.apogey.vrn.ru/menu_products/Apg_Stor-1mk.html). The signal code from the AKP-S 6 system unit 9 is transmitted to the locomotive radio station 11 via stationary radio stations 16 or 15 of the train radio communications of GMV and MB bands with a signal from the AKP-S6 via the TU-TS interface. Signal codes initialize the control system of the locomotive radio station 11.

Control of locomotive radio station 11 in the Test 2 and Test 3 modes is carried out on any channel in the GMO or MB wave range depending on the type of locomotive radio station by exchanging interaction signals over the radio channel on a dedicated radio frequency working channel channel. During the control, the interaction signals are evaluated along the MB or GMV ranges, the correspondence of the frequency deviation when making a call to the permissible value, the working capacity of the low-frequency path of the radio station, the serviceability of the checked radio station according to the results of its self-monitoring in TEST 1 mode.

When reading the test results of the locomotive radio station, the stationary radio stations 15 or 16 of the train radio are transmitted to the AKP-S 6 system unit 9. At the same time, the system unit 9 activates the IKSP 7 AKP-S 6, which receives the signals transmitted by the locomotive radio station 11 and measures their parameters, and namely the measurement of frequency deviation, accuracy of the carrier frequency, band of radiated frequencies, field strength, etc.

The measurement results of IKSP 7 AKP-S 6 are sent to block 8 of the AKP-S 6 for appropriate data processing. Unit 8 transmits the processed data to AKP-S 6 system unit 9. System unit 9 generates a message about the results of testing the locomotive radio station 11 and measuring signal parameters and transmits it over IP network 10 to server 2.

Server 2 analyzes the obtained data on the results of monitoring the status of locomotive radio stations along the route and generates a packet of information for each of them containing:

- date and time of initialization of the test,

- date and time of completion of the test;

- date and time of access to the server 18 AS EPL;

- date and time of formation of the “Plot Name” array, on the basis of which the check was carried out;

- a series of locomotive in text form;

- 4-digit (digital) board number of the locomotive;

- 4-digit (digital) train number;

- 5-digit (digital) code of the station to which the occupied block section adjoins, the name of the block section (text);

- 8-digit (digital) identifiers of sections of a locomotive;

- 4-digit (digital) codes of radio stations of the corresponding section of the locomotive for transmission over the radio channel;

- name of the locomotive registration depot (text);

- date of installation of the radio station (digital);

- type of radio station (text);

- identifier of the AKP-S that performed the verification;

- identifier of the ICSP that conducted the audit;

- the results of the check of the radio station.

Server 2 sends the generated information packet to shaper 3 to form a database of the status of monitored radio stations at the road level, as well as to the hardware-software device AWP 4 of the on-duty road monitoring center to visually display the results of monitoring locomotive radio stations.

If a deviation of the parameters of the signals of the locomotive radio stations 11 from the normalized values or a malfunction of the locomotive radio station along the route is detected, server 2 sends an information packet to server 19 of the ECMA 8, as well as via IP network 10 to the hardware-software device of the workstation 20 of the regional communication center, within service area which detected a faulty locomotive radio station 11.

In the depot, when the locomotive enters the flight in accordance with the adopted regulations on the railway, it is mainly at the driver’s initiative that they carry out pre-trip remote control of the locomotive radio station using an on-line pre-trip remote control device, for example, using the CTOP-1MK monitoring device. At the same time, the AKP-D 5 system unit 9 installed in the depot is in the mode of receiving signals from the operational pre-trip remote control device and from the locomotive radio station 11. Using one of the transceivers 12 or 13, depending on the type of locomotive radio station 11, the system unit 9 reads its number and transmits data about it over the IP network 10 to the server 2, which directs it over the data transfer network 17 to the server 18 AS ES.

When confirming the availability of data in the AS 18 server using this number of the locomotive radio station 11 of the passport data, server 2 sends the address signal codogram to the system unit 9 of the AKP-D 5 via IP network 10 to receive the results of testing the locomotive radio station by the automatic checkpoint AKP-D 5. and measuring the parameters of the signals of the radio station IKSP 7 AKP-D 5.

When reading the results of testing a locomotive radio station 11 with a transceiver 12 or 13, the AKP-D 5 system unit 9 activates the IKSP 7 AKP-D 5, which receives signals transmitted by the locomotive radio station 11 and measures their parameters, namely, measuring the frequency deviation, the accuracy of the carrier frequency, bands of radiated frequencies, field strength, etc.

The measurement results IKSP 7 AKP-D 5 sends to block 8 AKP-D 5 for appropriate data processing. Unit 8 transmits the processed data to AKP-S 5 system unit 9. System unit 9 generates a message about the results of testing locomotive radio station 11 and measuring signals and interference and transmits it over IP network 10 to server 2.

Server 2 analyzes the obtained data on the results of monitoring the status of locomotive radio stations in the depot and generates for each of them a package of information containing:

- date and time of initialization of the test;

- date and time of completion of the test;

- date and time of access to the AC 18 EP;

- 4-digit (digital) board number of the locomotive;

- name of the locomotive registration depot (text);

- date of installation of the radio station (digital);

- type of radio station (text);

- identifier of AKP-D, who performed the verification;

- identifier of the ICSP that conducted the audit;

- results of the check of the radio station.

Server 2 sends the generated information packet to shaper 3, as well as to the hardware-software device AWP 4 of the duty center for road control.

If a deviation of the parameters of the signals of locomotive radio stations 11 from the normalized values or a malfunction of the locomotive radio station along the route is detected, server 2 sends an information packet to the ECMA server 19 and via IP network 10 to the hardware-software device of the workstation 20 of the regional communication center, within the service area of which A faulty locomotive radio has been detected.

In addition, the system provides the possibility, from the hardware-software device AWP 4 or AWP 18, to set the IKSP 8 both AKP-S 5 and AKP-S 6 to the scanning mode of signals in all the radio frequency ranges operated on the railway, for interference analysis and spectrum of emitted frequencies, modulation parameters of third-party radiators; identification of radio facilities (matching locomotive radio facilities to stationary ones), search for unidentified radio facilities and direction finding of radio emission sources.

In this case, the control center duty officer or the regional communication center duty officer enters the appropriate command to the hardware-software device AWP 4 or AWP 19, which generates the corresponding control signal and sends it to north 2 for transmission to AKP-S 6 and AKP-D system unit 9 5 to activate the operation of the IKSP 7 in the scanning mode of signals in all radio frequency ranges operated on the railway, search for unidentified radio facilities and direction finding of radio emission sources.

Thus, the proposed system carries out operational control of the technical condition of locomotive radio stations and the correspondence of the parameters of the signals of the radio station to normalized values, which allows to reduce the number of emergency situations caused by malfunctions of locomotive radio stations, such as violation of the train schedule, reduction of the local speed values, etc.
