The technical field to which the invention relates is: traffic control on railways.

The level of technology. No prototype detected.

The essence of the invention.

The opportunity is used to represent the rolling stock treatment range as a well-known connected combination of elements, on any of which only runless single-row movement of rolling stock is possible, and the number of running wheels of any of its units at the input to the element and at the output from the element under normal operation remains unchanged.

The implementation of the invention provides the ability to automatically maintain the current location of the running wheels of rolling stock on rail vehicles.

It is focused on the following conditions of implementation:

- the use of simple outdoor sensors, not providing any additional equipment for rolling stock, which makes the method cost-effective;

- the use of hardware and software of computer technology for polling sensors, interpreting their readings, maintaining the current location of cash-controlled running wheels in the form of current oriented linear sequences of their identifiers by polygon elements and identifiers by polygon sensors as part of the corresponding automatic system;

- A well-known set of works on the development and implementation of systems at landfills.

To achieve the objective of the invention, an automatic system based on computer technology is created and implemented at the training ground, which implements the following provisions:

1. The landfill is conditionally divided into elements so that:

- each part of the polygon is included in one and only one element;

- the presence and single-line sequence of placement of the controlled running wheels on each element is changed only by their input or output (hereinafter referred to as “correspondence”) through the inputs / outputs (cross section of the rail track, through which the rolling stock is corresponded between the elements along the given rail track) from one or two ends according to the rule: “entered the element - became the first on the element from the input side at the time of entry completion, left the element - was the first on the element from the output side at the time the output started”;

2. At each input / output, such a sensor is installed and so that:

- in the area of its operation at any moment there can be only one controlled running wheel;

- Correspondence of controlled running wheels at the input / output is possible only in the range of the sensor installed at this input / output;

- relative to the zone of its action, at any moment one of the following necessary set of conditions is reliably determined: if there is no running wheel in the sensor's operating range, “there is no running wheel”; if there is a running wheel in the range of the sensor - "there is a running wheel in the known of the two parts of the range of the sensor located in series in the direction of the corresponding movement of the running wheels";

- these conditions are reliably recorded by the adopted survey system;

3. Since the beginning of the industrial survey of sensors:

3.1. The sensors are polled at a frequency that allows to reliably interpret the following state changes of any polygon sensor during the time from its previous survey to the given as the following corresponding full-scale movements of the controlled running wheels:

- from “there is no running wheel” to “there is a running wheel in a certain part of the sensor coverage area” as the full-scale input at the time of this survey into the coverage area of this running gear sensor, which was the first from the side of this sensor on the element adjacent to this sensor parts;

- from ““ there is a running wheel in a certain part of the sensor coverage area ”to“ there is no running wheel ”as its full-scale output at the time of this survey from the coverage of this sensor to the first place on the element adjacent to this part of the sensor from the sensor;

3.2. The state of each sensor surveyed is recorded in the definitions: “there is no wheel in the sensor coverage area”, “there is a wheel in a certain part of the sensor coverage area”; save at least information about the status of each sensor during the current and previous polls; in addition, information about the states of the sensors "there is a wheel in a certain part of the sensor coverage zone" is stored during the first survey, at least until the first use in the industrial dislocation management procedure;

3.3. Know what known element of the landfill or external is adjacent at the moment of fixing the input or output of the controlled running wheel to that part of the sensor coverage area in which the input or output is fixed;

3.4. By comparing the current and previous states of the sensor determine:

- the wheel enters a certain part of the sensor coverage area from an element adjacent to this side of the sensor, if the current sensor status is “there is a wheel in this part of the sensor coverage area”, and the previous “no wheel”;

- wheel exit from a certain part of the sensor coverage area to an element adjacent to this side of the sensor if the current sensor status is “no wheel”, and the previous one “there is a wheel in this part of the sensor coverage area”;

3.5. Information is stored about each entrance of the running wheel into the coverage area of each sensor and about each exit of the running wheel from the coverage area of each sensor, at least until the first use in the process of industrial dislocation of the running wheels of rolling stock at a given training ground;

4. To start industrial deployment:

4.1. Establish the true number of monitored running wheels located at the beginning of the industrial survey of sensors on each internal element of the landfill, except for those with inputs / outputs from one end (according to them, the establishment can be delayed for an indefinite time, during which the deployment of these elements will be carried out only relatively wheels that have entered or left these elements since the beginning of the industrial survey of sensors);

4.2. Uniquely identify each running wheel that was on the internal elements and in the coverage areas of the sensors of the landfill at the time of the beginning of the industrial survey of sensors, form the initial one-line set of cash identifiers of controlled running wheels for each element of the landfill, oriented relative to a certain end of the sensor, draw up a cash identifier in the area of each sensor a running wheel as an identifier of a wheel located in a certain part of the coverage area of the corresponding sensor;

5. In the process of industrial deployment of controlled running wheels at the landfill for each fixed entrance of the running wheel to the sensor coverage area and for each fixed output of the running wheel from the sensor operating range in increasing order of fixing time, and for the same time, in any order within such a sequence perform once:

5.1. At the entrance of the running wheel from an external element or an unidentified running wheel from a polygon element having inputs / outputs at one end, create a new running wheel identifier and design it as an identifier of a wheel located in a certain part of the coverage area of this sensor;

5.2. At the entrance of the running wheel from the polygon element, the identifier of the first running wheel from the side of the given sensor is excluded in the sequence of identifiers of the controlled running wheels on the element from which the wheel entered, and it is made out as an identifier of the wheel located in a certain part of the coverage area of this sensor;

5.3. Upon the exit of the running wheel to the landfill element, the identifier of the running wheel located in the coverage area of the given sensor is moved to the first place on the side of the given sensor in the sequence of identifiers of the controlled running wheels on the element on which the wheel has reached;

5.4. Upon the exit of the running wheel to the external element, the identifier of the running wheel included in the range of the given sensor is excluded;

6. Determine the violation of the provisions set forth in paragraphs 1 ... 5.4 of the provisions and implement the prescribed actions.

Information confirming the possibility of implementing the plan

Sensor availability

In railway transport, several types of outdoor wheel sensors are used in the control system for heating the axle box axle of the rolling stock to localize the overheating place in the form of the serial number of the wheel (axle) from the beginning of the train, and in the SAIPS system to turn on and off the data reading device of the on-board sensors; in connection with sufficient reliability, their information is occasionally used as the “last argument” in resolving disputes regarding the transfer of cars between railway units.

So, for example, the DPD-01 sensor has the following technical characteristics:

- working speed range - 0-300 km / h;

- the length of the zone of action of the wheel - 20 ... 25 cm in both directions from the center of the sensor;

- range of working temperatures - -40 ... + 50 degrees. school Celsius.

The exclusion of redundant elements and the device for working in an automatic polling system allows the use of this and similar sensors to implement the invention. It does not seem problematic to select other technical means - computer equipment, channel formation, energy supply, as well as programming and database tools.
