The scientific novelty of the solutions used in the innovative product.
Over the past 20 years, the existing trends in the development of weight control complexes for railway rolling stock indicate the need for automated non-foundation weighing systems that would not only transmit information about the volumes of goods transported, but also identify violations of cargo transportation and operation of rolling stock units. Consideration of the unity of the two tasks is due to the requirements for optimizing logistics and commercial accounting operations for the transportation of goods of enterprises, as well as minimizing the cost of maintenance of rolling stock during its active operation. The development of rail strain gauge scales by STATERA LLC – VRT is devoted to solving this problem.
Mainline weight control systems for railway trains in motion have already gained quite wide popularity among modernizers of railway infrastructure, however, many of them do not meet modern requirements for the functionality of weighing equipment in terms of parameters or technologies and methods used. Firstly, it is necessary to have information not just about the weight of the rolling stock, but about overloading/underloading or uneven loading of the wagon on the wheels during the movement of the vehicle through the measuring lines. Secondly, the developed system must meet the requirements for simple installation that does not violate the design of the existing operated rail track and does not limit the high-speed mode of transit trains. Finally, it is important to provide the possibility of remote monitoring of the working condition of the rolling stock, in particular wheel wear, in order to identify possible malfunctions of the wheels of the rolling stock at an early stage. The problems posed determine not only the technological significance of the solution, but also determine its scientific component – a method for diagnosing the technical condition of a rolling stock unit based on the vertical impact of a rolling stock wheel on a railway track.
VRT is a wagon scale that does not require mechanical modification of the track and is not inferior in characteristics to classical solutions. VRT is installed by adhesive method in the interstitial space on the operated rails. No construction work, no cutting, drilling, or any other mechanical intervention in the operated paths. Weighing is performed in motion without limiting the speed of transit rolling stock. The principle of operation of the VRT scales is based on the conversion of analog signals from sensors of rail deformation under the action of a wheel load into digital signals that are processed according to specified algorithms of the software being upgraded.
The information received is processed by the developed algorithms for analyzing defects and damages. The principle of operation of the algorithm is based on determining the measurement results that exceed the specified tolerance levels of the defect or are at the limit of acceptable values. According to the results obtained, a warning is issued to the user of the VRT software with data on the unit of rolling stock, the time of its registration and a conclusion on the degree of need to check a particular wheel.
As part of the research and development work, scientific research was carried out to determine the correlation estimates between the measured parameters and the parameters of wheel wear of rolling stock. Based on the available data on the relationship between wheel wear and the values of the measured parameters, the VRT system conducted an R&D dedicated to a significant modernization of the software for diagnosing the technical condition of a rolling stock unit based on the vertical impact of the rolling stock wheel on the railway track, and also implemented a software module of the decision support system to provide the PC operator with the most complete information on an alarming situation, in particular including detailed information about the diagnostic object. The operator will be provided with a scenario for responding to an alarming situation, while the response procedure will depend on the type of situation, the parameters of the rolling stock and the degree of threat. Scenarios will be developed as the software module for diagnosing the technical condition of rolling stock, as well as internal regulations of the enterprise, is developed and scaled. The rolling stock diagnostic system belongs to the Decision Support System (decision support systems) of the hybrid class, which includes data interaction models Suggestion models (a rule-based logical inference system) and File Drawer Systems (a system for providing access to the necessary data).
