The drawing shows a functional diagram of a radar control system for filling the sorting fleet.

The system contains a central computing complex 12, consisting of an Ethernet switch 10 with two computing computers 11 connected to it, synchronizers 6, each of which consists of a clock generator 9, an Ethernet switch 8 and an industrial controller 7 connected to a clock generator 9 and the input of the Ethernet switch 8, and the main remote modules 13, each of which includes a radar meter 3 connected via a signal processing and control unit 2 to an industrial computer 1, while receiver 4 and transmitter 5 antennas are connected to the measuring transmitter 3, the industrial computer 1 of each remote module 13 is connected to the clock generator 9 and the Ethernet switch 8 of the synchronizer 6, which is connected via the communication line to the Ethernet switch 10 of the central computing complex 12. To each main remote module 13, introduced a digital camera 14 and a central node 15 of the local communication network 16 connected to a digital camera 14 for transmitting data to a central computing complex 12, through an industrial computer ter 1 and 6 synchronizer.

The additional remote modules 17 contain digital cameras 18 connected to the communication nodes 19. The digital camera 18 complements the optical camera 14 of the corresponding remote module 13 in optical viewing, while in all the main remote modules 13 and additional remote modules 17 the communication nodes 15, 19 are connected to corresponding digital cameras 14, 18 digital communication interfaces, while the central nodes 15 of the local communication network 16, in each main remote module 13, are connected to the industrial computer 1, and all the main and additional Remote modules 13, 17 are located above the sorting park paths, mainly on the supports of the lighting network.

The control system filling the tracks of the sorting fleet operates as follows.

The system performs the following functions:

- ensuring the monitoring of rolling stock units throughout the sorting park;

- providing radar tracking of moving units of rolling stock from the moment they enter the sorting fleet to the moment the drawn train is drawn from the fleet;

- determining the location (coordinates) of all transport units of the rolling stock located in the control zone in real time;

- obtaining current information on the movement of units of rolling stock throughout the sorting park in real time. Computing computers 11 of the Central computing complex 12 performs the following functions:

- Communication with an external information integrated system for automated control of the sorting process (KSAU SP);

- synchronization and binding of a timeline;

- planning and dispatching of observations by radar meters 3;

- the formation and sending of source data for observations by radar meters 3;

- receiving data from the main remote systems;

- part of the primary signal processing;

- secondary statistical processing.

The synchronizer 6 performs the operation of self-construction of the delays of the clock signals with a large difference in the lengths of the connecting cables. The command for issuing the clock signals to the required pair of radar meters 3 is generated by the central computer complex 12 and transmitted via the Ethernet switch 10 to the clock generator 9, which through the Ethernet switch 8 of the synchronizer 6 and the industrial controller 7 supplies the synchronization signal to the two indicated radar meters 3 in a team.

During operation, the generator of the radar meter 3 emits sounding pulses. The receiver of the radar meter 3 receives the reflected signal from the specified range gate and processes this signal. Signal processing in the receiver of radar meters 3 in each sensing period includes three main stages:

- phase detection of the received signal with a reference signal, which is in the form of a copy of the probe signal of the transmitter;

- signal amplification;

- digitization of the signal and its transmission to the signal processing and control unit 2, which performs high-speed primary signal processing according to the moving average algorithm and transmits the processed signal to industrial computer 1, for its subsequent processing and transmission via an external interface.

Industrial computers 1 perform the following functions:

- self-identification in the network and network interaction;

- the submission of control commands in block 2 signal processing and control;

- synchronization and binding of the timeline;

- receiving and processing data from the signal processing and control unit 2 and from the cameras 14 and 18;

- part of the primary signal processing;

- sending the measurement results to the Central computing complex 12.

The system determines the following parameters of the position of the cutters on the territory of the sorting park:

- The speeds of the cut-offs, with an error in determining the speed of movement in the speed range from 0 to 1.5 m / s less than 5%, at speeds above 1.5 m / s and less than 2%; the minimum estimated speed of the cutters along the sorting paths is 0.2 m / s.

- Coordinates of aiming points for each sorting path (tail coordinates and cut length); the error in determining the coordinates of the stop of the trailer on the ways of the sorting park is determined by the density of the digital cameras 14, 18 and 1 m is selected.

The minimum fixed window length between the releases is determined by the density of the digital cameras 14, 18 and is selected to be 1 m.

Information on the speed of a moving trailer, as well as the coordinates of its movement on the tracks of the sorting fleet, is updated no less than through the time interval for which the trailer passes a path 5 meters long.

During the dissolution of trains, the central computer complex 12 generates and issues a control command to the corresponding main remote modules 13, in the area of responsibility of which the cut-offs will move. These main remote modules 13 go into standby mode. Additional remote modules 17 are in standby mode, with micro current consumption until receiving commands for photographing.

In standby mode, the strobe of the main remote modules 13 is set at a minimum range in the corresponding elementary field of view. The radar signal, from this minimum range, is constantly supplied to the central computer complex 12. When a clip appears in the gate, the main remote modules 13 generate information about the distance to the clip and its speed. After detecting the cut-off and determining its speed, the system switches from the “standby” mode to the “tracking” mode. The central computer complex 12 makes up the predicted trajectory of the cut-off, according to which the position of the strobe of the main remote modules 13 is controlled. The predicted trajectory of the cut-off is constantly adjusted based on the measurements obtained. Based on the adjusted route, information is generated about the coordinate of the stop of the release.

The system uses ultra-wideband radar meters 3 with a signal duration of about 4 ns. Each radar meter 3 observes in the area of responsibility limited by the width of its radiation pattern. Within this zone, radar meters 3 detect objects in narrow gates in range, the length of which lies within 1-0.5 meters.

At the same time, to measure the speed of the cutters and control the filling of the sorting fleet, they are irradiated simultaneously from several radar meters 3 arranged in rows, so that each mobile unit falls into the field of action of several radar meters 3 installed in the direction of travel, or acting after. The main remote modules 13 provide control of the speed of the cut-offs until they stop, and monitor compliance with the safe collision speed of the cut-offs. After fixing the complete stop of the next release and measuring its coordinate and the gap separating the release from the previous release by the radar method, the industrial computer 1 issues 16 commands on the local network 16 to photograph the area of the paths around the stopped release with cameras 14, 18 of its own and selected additional remote modules 17. In the calculations, industrial computer 1 integrates all available data from radar measurements and photography. Since the cameras 18 of the additional remote modules 17 are available angles in which adjacent trailers do not block free sections of the path, the accuracy and reliability of measuring the gaps between the trailers, compared with the prototype, is significantly increased. The local communication network 16, between each remote module 13 and, related to its control zone, additional remote modules 17, can be made in the form of a self-organizing network of low-power digital radio communications, for example, with a topology such as Mesh.

Such a connection contributes to flexibility in terms of the number and placement of additional remote modules 17, due to the small size and lack of wire connections. The power of the additional remote modules 17 can be organized autonomously from small rechargeable batteries, due to the low current consumption of the cameras 18 and the communication nodes of such a local network 16 in the photographing and information transfer mode and micro current consumption in standby mode.

The use of a self-organizing network of low-power digital radio communications also simplifies the process of debugging and trial operation of the system.

The data of increased reliability and accuracy, transmitted from the main remote modules 13 to the central computing complex 12 and further to the KSAU SP, allow more efficient control of the slide.
