The specified technical result is achieved by the fact that in the system of accounting for freight traffic by rail, containing at least one electronic mark installed directly on each unit of rolling stock, and a control device, each electronic mark containing a transceiver, identifier and controller, and the control device contains head transceiver, head controller, information processing and storage unit and long-distance communication unit, control device mounted on a locomotive train, all electronic tags and a control device are interconnected by a radio channel, each electronic tag is equipped with an additional sensor unit, and the control device is equipped with an additional head identifier.

Due to the placement of the control device on the locomotive and the formation of the radio channel connecting all electronic tags and the control device into a single network, the inventive system provides the possibility of continuous collection of information from electronic tags.

By equipping each electronic tag with a sensor block, the condition of the cars and the load is monitored for various parameters (the position of the shut-off mechanisms of the car, temperature and humidity in the car, the illumination of the car, cargo volume).

A comparative analysis of the design of the prototype and the claimed invention shows that the proposed system of accounting for freight traffic by rail is different in that in the claimed system, the control device is mounted on a locomotive of the train, all electronic tags and the control device are connected by a radio channel, each electronic tag is equipped with an additional sensor unit , and the control device is additionally equipped with a head identifier.

The structural diagram of the inventive system is presented in the drawing.

The system consists of electronic tags 1, placed on the railcars, and a control device 6, placed on the locomotive. Each electronic tag 1 contains a transceiver 2, an identifier 3, a controller 4 and a sensor unit 5. The control device 6 contains a head transceiver 7, a head controller 8, an information processing and storage unit 9, a long-distance communication unit 10 and a head identifier 11. The input of the transceiver 2 is connected with the output of controller 4, the output of the transceiver 2 is connected to the first input of controller 4, the output of identifier 3 is connected to the second input of controller 4, the output of the sensor unit 5 is connected to the third input of controller 4. Input the transmitter 7 is connected to the first output of the head controller 8, the output of the head transceiver 7 is connected to the first input of the head controller 8, the second output of the head controller 8 is connected to the first input of the information processing and storage unit 9, the second input of the head controller 8 is connected to the first output of the processing unit and storing information 9, the output of the head identifier 11 is connected to the third input of the head controller 8, the second output of the processing and storage unit 9 is connected to the input of the long-distance communication unit 10, the second input d block processing and storage of information 9 is connected to the output of the long-distance communication unit 10, all electronic tags 1 and the control device 6 are interconnected by a radio channel 12.

Identifier 3 contains the unique identification number of the electronic tag 1 and the number of the car on which this electronic tag is installed 1. The head identifier 11 contains the unique identification number of the control device 6 and the number of the locomotive on which it is installed.

The system of accounting for freight traffic by rail works as follows.

After completion of the procedure for the formation of the train, the operator loads into the control device 6 an electronic list of wagons containing information on the numbers of cars included in the train, on the position of each number in the train, on the type and quantity of cargo in each car. In addition, the list of wagons contains unique identification numbers of electronic tags 1 and control devices 6, stored in identifiers 3 and head identifier 11, respectively.

To initialize the system, the control device 6 using the radio channel 12 sends a broadcast request to the electronic tags 1. The electronic tag 1, which received the request via the radio channel 12, firstly relayes it, allowing the request to pass from head to tail of the train, and secondly, transmits a response to the control device 6 containing the identifier of this electronic tag 1.

The control device 6 receives the responses of the electronic tags 1 and compares the received identifiers of the electronic tags 1 with the identifiers available in the electronic list of wagons. Upon completion of the comparison procedure, the control device 6 initiates the transfer of electronic tags 1 information about the position of the corresponding car in the train. The control device 6 by means of the head transceiver 7 on the radio channel 12 alternately in accordance with the electronic list of wagons transmits to each electronic tag 1 the serial number of the corresponding wagon.

As a result of the initialization of the system, each electronic tag 1 receives information about the position of the corresponding car in the train, and the control device 6 receives information about the electronic tags 1 included in the system and about the cars that make up the train.

During the movement of the train along the route, the controller 4 of the electronic tag 1 with a given frequency interrogates the sensor unit 5 about the condition of the car and cargo. At least one of the following parameters acts as a controlled one: the position of the locking mechanisms of the car, the temperature and humidity of the air in the car, the illumination of the car, the volume of cargo. When the value of the monitored parameter falls outside the specified range, the electronic tag 1 generates an alarm message, which is transmitted via the radio channel 12 to the control device 6.

The control device 6 on the radio channel 12 sends a confirmation of the receipt of an alarm message to the electronic tag 1 that transmitted this alarm message, and using the long-distance communication unit 10 through a cellular or satellite communication channel transmits the relevant information to the traffic control service.
