The invention relates to a method and electronic device for monitoring the status of components of rail vehicles, in which sensors are used to register affecting the details of the loads measured values as input values served by the processing unit for analyzing the state of wear, and to do this by processing the signals is determined by the current location of the rail vehicle. In addition, the invention also applies in connection with this computer software product.
When the movement of rail vehicles is increasingly used systems diagnosis and control, in which are recorded, processed and stored in the memory of the various measured parameters. Among other things today, in addition to necessary for the operation of rail vehicle registration of the measured parameters of the drive and brake systems, such as speed, pressure, current and voltage are recorded and stored in the memory more measured values for the diagnosis of individual subsystems and components. Thus in addition to providing the required functionality is necessary to better assess the wear of parts, so you better use them for lifetime.
Rail vehicles which should not be considered when using it as a closed system, because it is constantly influenced by the interaction with the corresponding part of the way. Due to the various measured parameters in the vehicle, such as temperature and acceleration, you can also make a conclusion about the environment and, of course, about the status section of the route, in particular the adhesion at the site of contact of wheel and rail, or damage to the rail. Knowledge of the location and, thereby, under a certain point of the track section directly assumed. This currently requires additional devices, which provide the necessary location information.
From the document DE 10233527 B4 known method diagnostics and control of rail vehicle parts, namely, a guide device for a wheel in which the processing of the current measured signal of the acceleration and its double integration is the evaluation of the signal path. This signal path is then used as a status parameter for describing the coordinates of the current spatial position of the corresponding wheel pair relative to the other parts.
In document EP 0795454 A1 disclosed a method of simplemachi rail vehicle, which is based on the correlation obtained depending on the location of the spectra of the acceleration current andmore earlier trips. When this acceleration spectra represent a specific segment of the path and a specific vehicle ibroprofen this site, which is stored in the internal database as the reference memory and correlated with the actual measured acceleration spectra to determine the location of the rail vehicle.
In the document DE 60118501 D2 disclosed a method and apparatus for direction finding of a rail vehicle, which is determined by its speed on the track at different points in time and based on a special algorithm using database - the current location of the rail vehicle. In the database in addition to the geometric characteristics store other data, which were recorded by measuring the inertia in the previous passage of the vehicle.
In the document DE 19836081 A1 disclosed technical solution for the early detection of damage to rail vehicles. This control condition based on the analysis of unusual noises or vibrations, which signify damage to the rail vehicle. Heavy overload parts such as wheel pair, controlled by sensors. The latter produce the current values of noise and vibrations, which are compared with the soo is relevant reference values, lie whether they are within the specified limits. These reference values are stored in the reference memory and pre-determined for the points of the plot the way in which they have arisen before. To create a relationship between the current values of noise and vibrations and the corresponding reference values, the latter will be accessed many times and it is always when the sensors of vehicle components are appropriate point part of the way and produce the current message. Correlation of current sensor signals corresponding reference values is carried out by reading the arrows, which previously included in accordance with the progress of the vehicle along the track section.
In the prior art to obtain information about the location of the resort to additional devices, such as GPS receivers.
The disadvantage of this prior art is that the GPS receiver has a track vehicle is not always and even when available are not always produce an acceptable signal, such as passages of tunnels in mountainous areas can take a long track sections. In addition, many road networks, such as metro, are being caused by the system, limited capacity of transmission and reception, and thus the GPS direction finding can use the change only to a very limited extent.
To resolve this problem in the General prior art is also another possibility of determining the current location of the rail vehicle, in which are embedded directly in part of the way the position sensors inductive action of the transfer rail vehicle information about certain points of the path.
However, also this solution is associated with additional costs of appliances that should be planned when designing the rail vehicle and the track section.
Object of the invention is a method and electronic device for monitoring the status of components, obtaining location data which is simple and reliable.
This problem is solved by a method characterized by the signs of p. 1 of the claims. In relation to the respective electronic devices should refer to p. 6.
The invention includes the technological solution that the current speed v of the rail vehicle is recorded at time t, what you are creating v-t profile, which is correlated with the stored v-t profile to account for the stochastic comparison of both profiles to determine the current location of the rail vehicle to monitor its status. If this is what the correlation is expediently stored in memory v-t-profile in the profile section of the route/stop.
In other words, the fundamental idea of the invention is, therefore, that due to the correlation of the velocity profile with the profile of the section of the route/stop to determine the location.
The advantage of the proposed solution lies in the fact that for condition monitoring and analysis of the state of wear of parts and section of the route does not require any additional technical equipment for feed location data to the processing unit. On the contrary, the location information is only given when using the technique of signal processing, i.e., compute. Because the rail vehicle is moving mostly on permanent sections of the route with regular stops, you can display the underlying inventions criteria relating. Profile time stops when it is superimposed on a geographical map, the processing unit can determine which part of the route passed the rail vehicle and when and approximately where it was, how often it was slowed down between stops and where, for example, on the canvas of the roads are designated with a bad clutch. The stop time corresponds to the location of the stop, in which the velocity is zero within the established schedule length of stay at the bus stop. This allows you to create databases, to the verge for condition monitoring can be handled by simple statistical methods.
In the framework of the invention it is also possible that stored in memory v-t-profile are assigned to the other obtained through sensors and acting on the part of the load data. So, as an additional load data can be recorded affecting wheelset of a rail vehicle acceleration in order to identify the defective segments section of the route. You can even make a prediction about when the defective segment of a section of the route will reach the limit of wear, and use this information to proactively repair the defective segments section of the route before complete failure long before will require complex technical repair.
In accordance with one measure of the improvement of the invention it is proposed that as the device records the current speed of the rail vehicle at the time used the existing Central data logger. This achieves a further reduction in hardware costs. The Central data logger rail vehicle is designed to record the measured and calculated data along their temporal characteristics. In addition, proposed for monitoring the status of conservation used in order to compare the profile section of the route/stop rail vehicles in the region is the protection of data or processing unit. The profile section of the route/stop comprises in the simplest case, the temporal characteristic of the speed of the rail vehicle at the site of its movement in accordance with the current schedule with regard to speed limits on it. In addition you can also define the profile of the section of the route/stop through statistical analysis of historical measured v-t-profiles.
Other improvements of the invention are explained in more detail below together with the description of the preferred variants of its implementation with reference to the drawings, in which presents the following:

Measured values served as input values of the first to the recording unit 3, which receives the current speed v rail is on the vehicle from the control system (not shown) and records the time t. Unit 3 generates, based on this v-t profile rail vehicle, in which the input signal is connected to the block comparison 4. The Comparer 4 retrieves from the memory unit 5 stored in the v-t profile in the profile section of the route/stop rail vehicle, which was obtained using the schedule on the current section of road. Due to the stochastic comparison of both profiles are determined by the coincidence that the unit 4 provides the connected processing unit 6. The latter is used for monitoring and analysis of the state of wear of parts 1.
As shown in Fig.2, comparison of v-t-profile and profile b part of the way/stop is due to the fact that is indicated by the dashed lines fields are defined In the same time t. The region characterizes the time of stop of the rail vehicle when the speed v is equal to zero. Such a coincidence both of the profiles allows to make a conclusion about the reference profile b, i.e., where rail vehicle is really in the moment of time t0.
