Description

The utility model relates to control systems for moving objects and can be used mainly at the training grounds of railways by managing personnel.

A known system for controlling the movement of technological objects, implemented in a system for accurately determining the location of technological objects in railway transport (RU 87024 U1, 05/06/2009). The known system includes navigation equipment for an artificial earth satellite, equipment for consumers of satellite radio navigation systems, onboard equipment for automatic control and signaling installed on a technological facility, stationary stationary monitoring equipment for automatic control and signaling, a main and backup reference station, computers installed on an automated workstation of a dispatcher , a central computer processor connected to the memory unit and the output forming unit information connected to the monitor, to which the output of the signal processing and generation unit is connected, the coordinate converter, the input of which is connected to the output of the central processor, and the output is connected to the input of the signal processing and generation unit, the outputs of the consumer equipment units of the satellite radio navigation system for ensuring the location of technological objects of the primary and backup reference stations are connected to the inputs of the post unit of the automatic control and alarm system I by the radio channel unit is connected to the onboard equipment automatic control system and the alarms.

In the known system, using a network of reference stations, the differential correction to satellite measurements of navigation signals in real time is calculated, which allows you to determine the exact location of the technological object of the locomotive and thereby improve the efficiency of controlling its movement along the route.

However, when controlling the movement of a technological object, the state of the subsystems of the technological object and the state of the railway track are not taken into account, which reduces the efficiency of controlling its movement.

The closest analogue is a system for monitoring, tracking and control of land vehicles that implements the known method for a similar purpose (RU 2288509 C1, 11/27/2006). The system of monitoring, tracking and control of land vehicles contains an on-board complex common to all vehicles controlled by this system (TS), including on-board sensors, the outputs of which are connected to the corresponding inputs of the controller, and outputs connected to the executive bodies. The controller is connected to an autonomous navigation unit, which includes a GPS receiver. The airborne complex also includes an airborne terminal of a specialized relay-radio-direction finding network and an airborne terminal of a cellular mobile network. The on-board terminals are equipped with an antenna that provides reception / transmission of signals, respectively, through a specialized relay-radio direction finding network and a GSM network, and are connected to the controller through a switch. The system also includes a dispatch center, including a remote control terminal connected via radio or wired communication channels with base stations of a specialized relay-radio direction finding network.

The location of the transport object in the known system is determined using a satellite navigation system. At the same time, the GPS location signals received by the GPS receiver are specified using a relay-radio direction finding network. Moreover, the accuracy of determining the location of the transport object is not high. In addition, with respect to railway transport, the use of a relay-radio-direction finding network is not economically profitable, since it requires large material costs. It should also be noted that in the known system for controlling a transport object, data on the state of the track are not used, which is essential for railway transport.

The objective of the utility model is to create a system for managing transport objects at the railway landfill based on accurate information about the actual location of moving objects and the state of the movement path of the transport object, as well as the state of its main subsystems.

The technical result consists in the efficiency of decision-making on the management of transport objects at the railway landfill by using data on the exact location of the object, using data on the state of its route and the state of the subsystems of the transport object itself.

The technical result is achieved by the fact that the train control system at the railway training ground contains reference stations installed on the railway training ground and connected via a radio channel to the measuring equipment of the satellites of the space navigation system, a network center including a processing and control unit with a data archiving unit and a communication server, an on-board complex located at each transport facility, including a series-connected receiver of navigation signals, a correction unit and a transceiver the giving device, as well as the control and management unit, the corresponding outputs of which are connected to the executive control means, and the corresponding inputs are to the outputs of the control sensors of the executive control means, the other inputs / outputs of the control and control unit are connected to other outputs / inputs of the transceiver device, and the navigation signal receiver is connected via a communication channel to the measuring equipment of the space navigation system, while the automated workstation of the train display the control includes a central processor, connected to the inputs of the coordinate transformation unit, a display unit, a decision block, a state database of the paths and the transceiver with outputs, and inputs to the outputs of the coordinate transformation unit and the path state database, and one of the inputs a transceiver device, the other inputs of which are connected to the outputs of the decision block, the transceiver device of each on-board complex is connected via radio channels to a communication server of a network center and a receiving-transmitting device of the automated workplace of the train dispatcher, the last of which is connected to the hardware-software device of the automated workplace of the operator of the track distances via the radio channel.

At the same time, the transceiver on-board complex and the workstation of the train dispatcher are made in the form of multi-channel radio stations.

In this case, the other inputs / outputs of the monitoring and control unit 11 are connected to other inputs / outputs of the transceiver 1.0, and the navigation signal receiver 8 is connected via a communication channel to the measuring equipment 1 of the satellites of the space navigation system.

The workstation 14 of the train dispatcher includes a central processor 15, connected to the inputs of the coordinates converting unit 16, the display unit 17, the decision making unit 18, the path state database 19 and the transceiver device 20. The inputs of the central processor 15 are connected to the outputs block 16 coordinate conversion, the database 19 of the state of the paths and the first input of the transceiver 20, the second input of which is connected to the output of the block 18 decision.

The transceiver 10 via radio channels is connected to the communication server 6 and the transceiver 20.

The hardware-software device 21 of the automated workstation 22 of the distance operator (AWP PC 22) is connected through the corresponding transceiver 23 and the radio channel to the transceiver 20.

Transceivers 10 and 20 are made in the form of multi-channel radio stations.

The existing GLONASS or GPS systems are used as a space navigation system.

Each of the reference stations 1 is installed at a point with known coordinates and includes a series-connected satellite receiving antenna and a satellite dual-frequency receiver. All reference stations 1 can be interconnected by communication channels, which are used as general-purpose SPD channels used in railway transport.

Unit 4 processing and control of the network center 3 is made in the form of a hardware-software device that allows you to: collect measuring signals from each reference station in real time; processing of measuring signals by averaging signals; determination of the magnitude of the differential correction to satellite measurements of navigation signals in real time; transmitting the differential correction value to the user; post-processing of the measured signals; archiving the measured signals in block 5 data archiving.

The system for managing transport facilities at the railway training ground is used as follows.

The measuring equipment of the 2 satellites of the space navigation system emits radio navigation signals, including service and measurement information.

Radio navigation signals via radio channels are received by the antennas of the reference stations 1 and the receiver 8 of the navigation signals of the airborne complex 7 installed on the locomotive of each train.

At each reference station 1, the signals from the output of the antenna are transmitted to the receiver, which selects measurement information characterizing its coordinates.

The receiver 8 of the navigation signals of the airborne complex 7 emits measuring information characterizing the current coordinates of the train locomotive and the speed of the train.

Reference stations 1 transmit the measuring signals via a communication channel to the server 6 of the network center 3, which decodes them and sends them to the processing and control unit 4, which collects the measurement signals from each reference of station 1, processes the measurement signals by averaging the signals, determines the value of the differential correction to measuring the navigation signals of the reference stations in real time and transmitting the differential correction value to the user, as well as subsequent processing of the accumulated fixed information (postrobrabotku), with its archiving 5 archiving data block.

The processing and control unit 4 transmits in real time the differential correction value to the satellite measurements of the navigation signals through the communication server 6 to the transceiver 10. From the output of the transceiver 10, information about the differential correction value is sent to the corresponding input of the correction unit 9, to another input of which from the output of the receiver 8 receives information characterizing, including the current coordinates of the locomotive of the train.

Given the magnitude of the differential correction, the correction unit 9 calculates the exact coordinates of the location of the train locomotive. In real time, information about the exact coordinates of the location of the train locomotive located on the training ground, together with information about the measurement time and the speed of the train from the output of the correction unit 9, is transmitted to one of the inputs of the transmitter-receiver 10. Simultaneously to the other input of the transmitter-receiver 10 from the output of the control and control unit 11, information is received about the train number and the state of its individual subsystems. The transceiver 10 generates a data packet and transmits it over the communication channel to the input of the transceiver 20 APM PD 14, from the output of which it is transmitted to the input of the central processor 15.

The central processor 15 converts the received information, extracts information about the exact coordinates of the train and transfers it to the coordinate conversion unit 16, which coordinates the train coordinates to the railway coordinates. Information about the railway coordinates of the train is transmitted to the corresponding input of the central processor 15. The central processor 15 converts data on the exact position of the train at the training ground, its speed and the status of individual subsystems for visual presentation on the monitor of the information display unit 17. Thus, the train dispatcher in real time monitors the exact position of the trains controlled on the site.

It is known that at the railway training ground, track workers constantly diagnose the track’s upper structure (rails, rail supports, ballast), the results of which are sent to the hardware-software device 23 of the track distance AWP (AWF) 22, the central processor of which processes the received data, summarizes, analyzes and stores in his memory. In addition, information about the state of the rail track and the exact location relative to the rail coordinates of rail damage and track deviations from standard values is entered into the memory. All this information through the transceiver 10 through the communication channel is transmitted to the input of the transceiver 20 APM PD 14, which transmits it to the central processor 15 AWP PD 14. The central processor 15 converts it and sends it for storage to the database 19. Thus, the database 19 on the status of the train track at the railway training ground is constantly updated.

After receiving the data in the railway coordinates on the location of the train, the central processor 15 requests from the database 19 data on the status of the train track at the train section and analyzes it taking into account the exact location of the train in real time. According to the results of the analysis, taking into account the speed of the train and the state of its individual subsystems, decision-making block 18 issues appropriate recommendations for controlling the movement of the train.

Recommendations for controlling the movement of the train from the output of decision block 18 through the transceiver 20 through the communication channel are transmitted to the input of the transceiver 10 of the airborne complex 7 of this transport facility, which transmits it to the control and control unit 11 to establish optimal operating modes for the executive funds 12.

In case of emergency situations that threaten traffic safety at the site of the transport facility, in emergency cases requiring immediate intervention in the facility’s control process, the central processor 15 generates an alarm signal on the monitor of the display unit 17, and the train dispatcher transmits via the train radio channel or transmits to the train driver a speech signal for braking, stopping or changing the operating mode of the train, or using block 18 forcibly generates a signal for braking, stopping or and changing the mode of operation of the train.

Thus, the train dispatcher is able not only to control the position of the locomotive in the section, but also to quickly take measures to prevent non-standard and emergency situations along the train based on information about the exact location of the vehicle on the section of the track and information about the state of the section of the track obtained in the result of the diagnostic work is not only the linear workers of the track, but also control and measuring instruments, readings of measuring trolleys and wagons.
