The invention relates to control the railroad tracks and can be used, in particular, in the system of distributed control track and monitor the status of wear and serviceability of the arrow, switch, rail joints rail etc.
A known system for monitoring railway track (in particular, for the diagnosis and monitoring of the arrow, cross, switch and rail junction railway), containing the acceleration sensors located on a constructive element of the rail vehicle, and located on the rail vehicle speed gauge, navigation device and the data acquisition device, intended for processing, recording and evaluation of the measuring signals of the acceleration sensors, speedometer and navigation device and provide forecasting necessary repairs and the associated costs for repairs (EN 2349480, UK 9/08, 27.10.08).
A disadvantage of the known system is the relatively low reliability of the control, due to the placement of the measuring acceleration sensors on a track vehicle. After processing, measurement signals and compares those characteristics with prescribed boundary values measured vibration accelerated the th, there is a necessity (if specified values of vibration acceleration is exceeded) to conduct a subsequent (re -) more thorough measurement condition of the railway track.
The technical result of the invention is to improve reliability of the control track.
The technical result is achieved by the fact that in the system of distributed control track containing the vibration sensors and placed on a movable object, a data acquisition device, according to the invention, the data collection device is placed in the head part of the rolling object and consists of a microcontroller that is connected to the transmitter, the receiver and the block of output data, and in the rear part of the movable object placed transceiver module, the transmitter which is connected by the internal communication channel with the receiver of the data collection device, the power input of receiver and transmitter transceiver module connected to the power source, consisting of the energy Converter connected to the energy accumulator, the output of which is the output of the power source, the controlled section of railway track posted by the measuring module, consisting of a receiver, the output of which is connected to the energy storage device, the transmitter, the input connected to the output of the microcontroller,to the inputs through which the connection unit is connected to the vibration sensors, mounted on rails or sleepers controlled area, and temperature sensors mounted on the rails of the controlled area, and the output of the energy storage is connected to the power input of the microcontroller and transmitter.
The drawing shows a diagram of the proposed system distributed control track.
The system of distributed control track contains placed in the head part of the rolling object device 1 data collection consisting of a microcontroller 2, is connected to the transmitter 3, a receiver 4 and block 5 output information, and in the rear part of the movable object placed transceiver module 6, which includes the receiver 7 and the transmitter 8, which is connected on the inner channel 9 communications with the receiver 4 of the device 1 of the data collection, the power input of the receiver 7 and the transmitter 8 transceiver module connected to the power source, consisting of a transducer 10 energy connected to the drive 11 energy whose output is the output of a source power on controlled section of railway track posted by the measuring module 12, consisting of receiver 13, the output of which is connected to the drive 14 of the power of the transmitter 15, the input connected to the output of the microcontroller 16, the input of which is through the block 17 pairing the connected sensors 18 vibration, C is fastened on the rails or sleepers controlled area, and sensors 19 temperature, mounted on the rails of the controlled area, and the output drive 14 power connected to the power input of the microcontroller 16 and the transmitter 15.
The system of distributed control track works as follows.
With the passage of the controlled part of the way the transmitter 3 of the device 1 of the data collection, placed in the head part of the rolling object, emits a powerful signal that arrives at the input of the receiver 13 of the measuring module 12. As the movable object may be a locomotive or car, used vehicle. In the receiver 13, the signal is subjected to rectification and then flows into the accumulator 14 energy, where there is rapid accumulation of received energy. At the output of the memory 14 receive a voltage that is supplied to the power input of the microcontroller 16 and the transmitter 15. Thus, the measuring module 12 is activated and sensors 18 and vibration sensors 19 temperature goes through the block 17 pairing information to the microcontroller 16. The microcontroller 16 performs pre-processing received from the sensors 18 and 19 of the information. The sensors 18 vibration is fixed on the rails or sleepers controlled area, and the sensors 19 temperature are fixed on the rails. The location of the sensors on the controlled area and mount them directly n the objects of control allows higher precision to make measurements of controlled parameters and therefore, to increase the reliability of the control track and provide a more objective assessment of the status of the monitored track. Using the transmitter 15, the processed information is transmitted in the transmitting-receiving module 6, placed in the rear part of the movable object. The power receiver 7 and the transmitter 8 transceiver module 6 is supplied from the drive 11 of the energy connected with the output of the Converter 10 energy. The Converter 10 may be performed on the piezoelectric elements which are responsible for converting the mechanical energy of vibration into an electric signal, or photovoltaic that converts light energy. From the output of the receiver 7 transceiver module 6 adopted by the information received at the input of the transmitter 8, which inner channel 9 communications transmits the information received in the receiver 4 of the device 1 of the data collection.
Channel 9 may be implemented as a wireless or wired link. From the output of the receiver 4, the received information is supplied to the input of the microcontroller 2, which performs the final processing of information with regard to all measured parameters, including temperature rails, and transforms in appearance, convenient to display it with the help of block 5 output.
Due to the fact that the measuring module 12 of the act is vinuesa signal, radiated by the transmitter 3, which device 1 data collection, placed in the head part of the rolling object and the reception of information, provides the receiver 7 transceiver module 6, placed in the rear part of the movable object, there is considerable margin of time for processing signals coming from the sensors. This in turn provides the desired reliability and validity of the results.
The measuring module 12 does not contain a source that is powered from the network or a standalone power source, such as rechargeable batteries. It is powered by the energy of the signal emitted by the transmitter 3 at the moment of approach of the head part of the rolling object to the testing area path. Therefore, the measuring module 10 connected to the measuring sensors can be used to control any selected section of railway track, i.e. where there is no connectivity to the network voltage source or no ability to provide the required frequency of maintenance (in particular, to replace raredisease source of Autonomous power - battery). Transceiver module 6, placed in the rear part of the movable object, also no network power supply or stand-alone (battery). His food is sudestada from the energy Converter, which does not require frequent periodic maintenance.
