Description

The utility model relates to systems for detecting the precautionary state of a node on rolling stock of railway rolling stock, but can also be applied to metro trains.

In modern conditions of operation of complex technical objects, one of the important points in assessing the current state of their systems is increasingly becoming the possibility of organizing "information visibility" of the equipment of the object. This possibility is achieved by periodically remotely monitoring the values of a certain set of operating parameters of an object, implemented by organizing information flows in the system.

The ability to control and compare the values of these parameters with acceptable indicators allows us to evaluate the performance of the system, timely identify the precautionary state of the node, and track the dynamics of changes in any of the controlled parameters over time. In addition, it is possible to optimize the process of maintenance and repair of site components due to the fact that in the first place it will be necessary to service or repair those units and parts whose parameters during operation have gone beyond the permissible values.

Such systems are known abroad as “event-driven fault diagnosis” systems (see, for example, US patent No. 2010730883 from 2010.0324).

A similar system provides monitoring and feedback for a vehicle relative to its location based on at least the information provided by sensors located on the vehicle. In addition, information formulated on the basis of additional criteria received from other systems, with the exception of the aforementioned sensors located on the vehicle, for example, meteorological systems, geographical location systems, a radar system, a global coordinate determination system, etc., can be transmitted by feedback. d. The information provided by the sensors for feedback can be stored in the memory of the vehicle, or on a fixed object for archiving and subsequent analysis (see US patent No. 7113852 "System and method for monitoring and controlling a vehicle with feedback".

The main disadvantage of the known system is that monitoring the current state of the nodes of the rolling stock is possible only when it is placed in the repair position of the depot. There is no possibility of fixing the fact of deviation of any of the controlled parameters from the norm, as well as the values of other parameters at a given time during the direct operation of the rolling stock.

The objective of the utility model is to provide control of the main parameters of the functioning of the nodes and systems of rolling stock during the overhaul period of operation. Such an opportunity will make it possible to optimize the organization of maintenance and repair (including inter-train) of rolling stock, taking into account the events that have actually occurred, related to the failure of specific components and systems along the train.

The problem is solved in that in the known monitoring system for rolling stock, mainly rolling stock of the metro, containing standard sensors for warning of technical malfunctions, signaling devices about malfunctions installed on rolling stock and connected by communication lines into a single warning system for technical malfunctions, which according to a utility model, the system is additionally equipped with on-board elements of measurement, primary processing, accumulation and transmission of physical data the values of the nodes operation parameters, connected by communication lines with standard warning sensors, and is also equipped with stationary posts for reading information from rolling stock and data transfer channels from posts for reading information to the server of the repair control center in the depot.

The following distinguishing features prove compliance with the criterion of "novelty" of the claimed utility model:

1. The presence on the rolling stock of a set of primary converters of mechanical, electrical and other parameters of the nodes into signals available for transmission on train communication lines. As primary converters it is possible to use both sensors of standard on-board systems, and additionally installed.

2. The presence on the rolling stock of primary processing devices for storing and transmitting information received from primary converters.

3. The presence on the rolling stock of channels for transmitting information from primary sensors to devices for processing, storing and transmitting data.

4. The presence in the depot of posts for reading information from rolling stock.

5. The presence in the depot of data transmission channels from information reading posts to the server of the repair control center (repair dispatcher).

The systems developed by the applicant for the collection, processing and transmission of data in the aggregate of the above characteristics make it possible to implement the task of organizing "information visibility" of nodes and systems of technical objects of almost any complexity, including such as subway train cars.

In the framework of the claimed utility model, the construction of an information system for monitoring the current state of nodes and systems of subway cars in operation is a complex task, the solution of which should include the following components:

1. Equipment of train cars with primary converters of mechanical, electrical, and other parameters of the nodes operation into signals available for transmission via train communication lines.

2. Equipment of train cars with devices for the primary processing of signals received from sensors, as well as the accumulation, storage and transmission of information to external devices. In addition to the function of collecting and processing data from their own sensors, these devices have the ability to process information received from on-board monitoring systems.

3. Creation of depot reading posts, providing for reading information from transmitting devices of train cars for its subsequent transfer to the depot data processing center before placing the train at a repair position for maintenance, current or inter-train repair.

4. Creation of data processing centers in the depot, processing information coming from the corresponding depot reading posts. The main tasks of the data center in the depot should include:

- control of train modes;

- assessment of the current technical condition of nodes and systems of wagons in the format "norm" / "not norm" or, if necessary, in comparing the current values of operating parameters with acceptable ones;

- identification of the precautionary state of the nodes of wagons;

- making decisions on the possibility of further operation of cars, planning their maintenance or repair;

- decision-making on the scope of the repair work of the wagons when they are received for maintenance or TR;

- the formation of orders for specialized repair crews to perform work;

- generation and transmission of summary reports on the condition of nodes and systems of train cars to the technical services of the Metro Office;

- prompt notification of the involved services about the failure of the unit or system of the carriage in operation.

- prompt notification of depot managers about the failure of the unit or system of the carriage in operation;

5. Creation of information systems for repair process management or depot repair control centers on the basis of the depot.

The depot repair control center provides organization and management of the technological process of car repair, including the organization of equipment and accounting of spare parts and materials. Information received by the dispatcher repair control center dispatcher from the depot data center allows you to plan and adjust the repair work, taking into account possible failures of the carriage equipment on the line.

The operation of the depot repair control center is ensured by specialized equipment, including technological equipment of repair shops, which is capable of generating and transmitting protocols for performing diagnostic checks or testing units and parts of carriage equipment after repair. The functional execution of technological equipment minimizes the intervention of a specialist in the process of conducting inspections or tests, increasing the reliability of the operations performed.

6. Creating channels for transmitting information at all levels of the information system.

The utility model is illustrated by the scheme of data transmission from train cars to technical depot services.

The system contains primary converters 1, 2 ... (n) of mechanical, electrical and other parameters of the nodes into signals accessible for transmission via train communication lines 3, all levels of the information system, airborne systems 4 for collecting, primary processing, accumulation and transmission received from sensors 1 ... n signals, as well as the accumulation, storage and transmission of information to external devices, depot reading posts 5, which provide reading information from transmitting devices of onboard systems 4 train cars, data center 6 in the depot, The centers (information systems) for repair management of 7 depots at specialized posts that process information coming from the corresponding reading posts of 5 depots 8. The processed information is transmitted to a single center for monitoring rolling stock 9.

The functioning of the constituent elements of the system provides for the following organization of information flows.

On the route of the train from the nodes of the wagons using the standard sensors of the on-board systems, as well as additionally installed sensors 1 ... n, with a certain periodicity, primary information is collected on the current values of a certain set of operating parameters of the equipment. These parameters include:

1. The operation parameters of the nodes of the running group (traction motors, traction drive, traction reducer, wheelsets).

2. The operation parameters of mechanical equipment (nodes of spring suspension, automatic couplers).

3. The parameters of the power electric transmission.

4. The operation parameters of auxiliary electrical equipment.

The primary information from the sensors 1 ... n via train communication lines 3 enters the primary signal processing devices of the airborne systems 4, where the obtained values are compared with admissible ones and are stored in the form of protocols and stored for subsequent transmission to external devices of reading depots of 5 depots. The discreteness of information transfer is determined by the period when the train calls for maintenance (on average every 20 hours) and is carried out via wireless communication channels before placing the train at the depot repair position.

The received block of information is processed in the data center of the 6th depot and in text-graphic format is transmitted to the dispatcher of the repair control center of the 7th depot. This information is the basis for assessing the current technical condition of nodes and systems of cars arriving for maintenance (TR) or current repair (TR), making decisions on the scope of repair work of cars on TR or TR. Formation of orders for specialized repair crews in workshops 8 for the implementation of repair work on nodes, with this approach, is carried out automatically. First of all, in the task assignment, nodes are displayed for which the values of the operating parameters in operation have deviations from the permissible values and solutions to other production problems.

Monitoring the process of repairing cars is carried out through mobile and stationary monitoring and diagnostic systems. In the process of performing work, information on the repair of equipment is recorded in the database. Electronic equipment testing protocols are the information platform of the repair control center 7. In on-line mode, this information is displayed on information monitors located in repair shops 8 and offices of company managers in the form of a generalized diagram of the readiness of the staff to exit the repair.

These diagrams make it possible to evaluate the enterprise’s compliance with the standards for car downtime on the appropriate type of repair, to identify critical elements in the repair process chain that “inhibit” the repair program and require the necessary corrective measures. Charting involves the use of working fields, for example, in the following color design.

The green color indicates the process of repairing the equipment of wagons, the implementation of which corresponds to the established norms of time for carrying out technological operations provided for by repair documentation.

The yellow color indicates the repair process, the implementation of which is ahead of the established schedule of work, which may indicate a complete or partial failure to perform some technological operations.

The red color indicates the repair process, the implementation of which is behind the established schedule of work, which may indicate a problem during some technological operations.

The color representation of the information in the diagrams simplifies data analysis and stimulates depot workers to improve the quality of their work.

Upon completion of maintenance or repair, the dispatcher of the repair control center forms a certificate of the readiness of the staff to exit the repair and sends it to the duty officer on the depot.

Summary information on operating modes, timing and quality of repairs from all depots goes to a unified monitoring center 9 of the rolling stock, where it is analyzed by a special analytical group and, in case of incorrect operation of the repair and operation system as a whole, corrective measures are taken.

Industrial applicability is ensured by sufficient experience in the production of such systems.
