System diagnostics railway operates as follows.
As space navigation systems use GLONASS and/or GPS, and the transceiver 9 of the navigation signals of space navigation system reference station 8 is configured to receive navigation signals as GLONASS and GPS systems.
Each of the reference station 8 is installed on a point with known coordinates and includes a satellite receiver. All, another station 8 interconnected by communication channels, which are used used on railway transport channels obshheehkonomicheskogo destination SAP.
The server 11 provides communication connection unit 12, the processing and control network center 10 with referenznumme stations 8, transceiver blocks 7 potenzmitteln trucks 1, which may be one or more, and the external system 17 warning track teams. Unit 12, the processing and control network center 10 made in the form of hardware and software with the following functions:
collecting measurement signals from each referencei station 8;
- processing of the measuring signals by averaging;
- determining the size differential correction to satellite measurements of navigation signals in real time;
- transfer the values of differential correction;
- post-processing of the measured signals;
- archiving of the measured signals in the block 13 archiving data.
Unit 3 measuring geometrical parameters of the path contains a sensor of the traversed path, designed to determine the magnitude and direction of trolley movement 1, forming clock pulses for operating the control system 2 in increments of, for example, 0.125 m coordinate of the path of the pendulum level sensor for level measurement of rail lines and the linear displacement sensor for measuring track gauge.
The control and computing system 2 is made in the form of hardware and software devices, which in real-time captures the geometric measurement of parameter the path and positioning signals potenzmitteln truck 1, considering the magnitude of differential correction clarifies the values of signals positioning potenzmitteln truck 1, detects deviations of the actual path settings from the design values, and performs the "binding" measurement of geometrical parameters of the path of the adjusted coordinates of the path.
Network center 10 is connected with the transceiver unit 7 placed on potenzmitteln cart 1, and the external system 17 warning track teams channel of mobile communication, such as GSM channel. In this case, the transmitting unit 7 is designed as a GSM modem.
The receiver 4 of the navigation signals emit signals of GLONASS / GPS measurement information to indicate coordinates of the truck 1.
Another station 8 transmit measuring signals via the communication channels in the server 11 and the network center 10, which decodes them and sends to the block 12 processing and management, collecting measurement signals from each referencei station 8, the processing of the measuring signals by averaging signals, determining magnitude of differential correction to satellite measurements of navigation signals in real time, the transmission values of differential correction to the user, subsequent processing of the accumulated data for archiving in block 13 archiving data.
Unit 1 processing and control transmits in real time the amount of differential correction to satellite measurements of navigation signals via the server 11 communication transceiver block 7, from which it is fed to the input of the control and computing system 2. To another input of control computer complex 2 from the output of the receiver 4 of the navigation signals received signals characterizing the location coordinates potenzmitteln truck 1.
Considering the magnitude of differential correction control computer system 2 calculates the exact location coordinates potenzmitteln truck 1. At the same time in the control computer system 2 receives information from unit 3 measuring the geometrical parameters of the path, installed on potenzmitteln the trolley 1.

The most reliable option is mutual redundancy of communication channels for communication with the server 11 for communication and interaction with the external system 17 warning track teams. In this case, the communication channels are transmitted not only information on potenzmitel truck 1 to alert them from the external system 17 warning track teams, but also to the external system 17 warning track teams receives information from potenzmitteln trucks 1 on t is cnyh the location and information about approaching him train, recorded on potenzmitteln trucks 1 on the acoustic noise signal propagating from approaching trains over the rails.
This signal through a pair of wheels potenzmitteln truck 1 is perceived sensitive elements of the block 18 acousto-electric transducers and converted into electrical signals. The electrical signals are processed by the processor 14 digital signal processing to determine the degree of approximation and speed of approaching trains. Processing uses the known methods of measurement and analysis of the rise of the amplitudes of the spectral components of the signals approaching trains. The presence of the block 18 several acousto-electric transducers associated with the various wheels of the truck, provides a specified security conditions, the confidence level of control and additionally determines which side or which way they train coming. In particular, with potenzmitteln trucks 1 through the external system 17 alerts travel teams may be transmitted request signal emergency stop approaching trains, if the operators are not confident enough to remove his potenzmitteln cart 1 from the path.
The indicator unit 5 indicating a connection with the network center 10 shows the connection between the network center 10 and the transceiver before the current block 7 potenzmitteln truck 1, as well as the connection with the external system 17 warning track teams. In addition, in text mode, it can also display text warnings about approaching trains and other technological information and graphical display of the train situation and whereabouts of employees of the path in the location area potenzmitteln truck 1 on the basis of data sent by the external system 17 warning track teams.
Potenzmitteln truck 1 stores offline opportunity alert related workers ways of approaching trains, regardless of the presence or absence of communication with the external system 17 warning track teams. When data is received on a train is approaching, the CPU 14 digital signal processing control and computer system 2 includes a block 15 local alert operators audio, speech, and light signaling the approach of a train. If you have a local network radio with closely spaced employees the way, the latter can also be notified of the approach of trains through the links posted on potenzmitteln trucks 1 without external equipment systems 17 warning track teams.
In the detection of approaching trains and alert operators potenzmitteln trucks 1 and workers is of utivich teams in several independent ways, as well as the possibility of transmission to the external system 17 alerts travel teams the exact coordinates of the location and requests for emergency stop trains the inventive system provides a high level of security when performing track work. Due to the sharing of communication channels and parts of blocks at the same time for the purposes of external warning systems and for the purposes of diagnosing the way of saving hardware.
