Description

The invention relates to the field of railway transport, and in particular to devices for generating an information model of a train with a designation from the head of the train the serial number of the moving unit, type of moving unit (locomotive or wagon), the number of its wheelsets (KP) and the serial number of each KP of the train relative first KP from its head.

This information allows you to expand the functionality of automated systems used in railway transport. In particular, it becomes possible to relate information received from distillation devices for monitoring certain parameters of PEs, information read out from identifiers of PEs and its individual elements, as well as from identifiers of goods transported by these PEs to specific mobile units (ПУ) and КП trains.

A known method and device for determining the serial numbers of PEs of a moving train on the basis of recording the interval between PEs using industrial IR or laser sensors, for example, Connect 3 series W 18-3 WS / WE 18-3 photoelectric sensors, MIK-02, Perimetr, PE30P / PE60P, Aleph AVT-30/60/120, used in the Transit - Inspector PRO system [1], as well as the RTD-S radio sensor [2].

The disadvantage of these methods and devices is that their operation depends on weather conditions, and / or they do not allow to determine the serial number of the PE in the case when the train makes maneuvers with a change in direction.

A known method and device for determining the serial numbers of cars of a moving train on the basis of detecting gaps between cars using electromagnetic radiation, which ensures the independence of the work from changing the direction of movement of the train and weather conditions (see, for example, patent RU 2627254, publ. 04.08 .2017, IPC B61L 1/16, or patent US 8655540, publ. 02/18/2014, IPC B61L 1/16).

The disadvantage of these technical solutions is that they do not determine the type of moving unit of the train (a locomotive or a car). And this must be determined, for example, when building automated systems for securing train composition on station tracks.

», опубл. 18.07.2002, МПК B61L 1/16; B61L 25/02, в котором «осуществляется набор данных, идентифицирующих типы вагонов в железнодорожном составе и их относительные положения, путем измерения расстояний между осями колесных пар поезда и сравнением измеренных значений с предварительно сохраненными в памяти контроллера значениями расстояний между осями, характерными для разных известных типов вагонов». Межосевые расстояния в проходящих подвижных единицах поезда в этом способе измеряют с помощью двух рельсовых датчиков колеса (РД), расположенных вдоль участка пути на некотором расстоянии «В» меньшем минимально возможного межосевого расстояния всех существующих на сегодня железнодорожных подвижных единиц.There is also known a method of forming an information model of a train moving along a control section of reading parameters of a train, determining from the head of the train the serial number and type of each mobile unit (this locomotive, freight car, refrigerator, etc.), the number of wheelsets in each mobile unit and serial the numbers of each wheelset of the moving unit relative to the first wheelset from the head of the train - patent DE 10064598 for the invention "Railway train configuration data set generation method identifies different wagon types from their measured axle

", Publ. 07/18/2002, IPC B61L 1/16; B61L 25/02, in which “a set of data identifying the types of cars in the train and their relative positions is carried out by measuring the distances between the axles of the wheelsets of the train and comparing the measured values with the distance between the axles characteristic of various known types of wagons. " The center distance in the passing moving units of the train in this method is measured using two rail wheel sensors (RD) located along the track at a certain distance "B" less than the minimum possible center distance of all existing railway moving units.

The disadvantage of this method is the dependence of the reliability of its operation on accelerations and a possible stop of the train when moving along the reading section of the train parameters.

There is also known a device for counting mobile units of railway transport, the reliability of which does not depend on weather conditions, nor on possible accelerations, nor on stopping and changing directions of a train moving through a control section for reading train parameters (patent SU 1284870, publ. 23.01. 1987, IPC B61L 1/16; B61L 17/00). The device contains reversible point track sensors installed on the path, a PE tracking unit, connected by an output to the first input of the PE axis determination unit, the first output of which is connected to the first input of the first PE type determination unit, the second input of which is connected to the output of the first sign-fixing block units, the device is also equipped with blocks for controlling the freeness of the site, a trigger, elements AND, OR, OR-NOT, additional blocks for fixing the sign of a moving unit, additional blocks determining the type of mobile unit, and an additional reversible track sensor, and the outputs of the first, second, third and fourth reversible point track sensors are connected respectively to the first inputs of the corresponding first and second block of control of the free section, to the second and first inputs, respectively, of the first and third blocks of the free control of sections , to the first input of the block for tracking the PE, the second inputs of the block for determining the axis and the second block for controlling the free section, to the second input of the third block for controlling the freedom of the section, the outputs of the first and third blocks for controlling the freedom of the section are connected to the inputs of the OR-NOT element and to the first inputs of the first and second blocks for fixing the sign of PE, the second, third and fourth inputs of each of which are connected respectively to the output of the second block of freedom plot connected to the first inputs of the trigger and the second unit for determining the type of PE, to the first output of the trigger connected to the second and third inputs, respectively, of the block fixing the trace of PE the unit for determining the axis and the output of the unit for fixing the trace of the PE connected to the first input of the third block for fixing the sign of the PE connected by the second input to the output of the OR-NOT element, the second input of the trigger, the second, third and fourth outputs of the block of determining the axis are connected to the first inputs of the AND element, respectively , the first OR element and the third block of type ПЕ determination, the first and second outputs and the second and third inputs of which are connected respectively to the first inputs of the second and third OR elements, to the output of the second block признак сации П к Е и и и и и и и признак признак сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации сации X from the second input from the And inputs of the second input unit and the second block of the determination of the type of PE, to the third inputs of the block to fix the trace of the PE and the first block to determine the type of PE, the first and second outputs of which are connected to the second inputs of the second and first elements OR, the last of which is connected by the output to the third input of the second unit for determining the type of PE, the fourth input and the first and second outputs of which are connected respectively to the output of the third block for fixing the sign of PE and with the third and second inputs respectively of the second and third elements or the third input of the latter connected to the output member I. This device is taken as a prototype.

The disadvantages of the prototype are the large number of equipment used and the limited functionality of its application. So, in the prototype it is said that “the distance between the sensors 1 and 4 (4.7 m) is equal to the sum of the distances between the sensors 1 and 2 and 2 and 4 and, at the same time, is less than the minimum distance between the wheeled carts ПЕ (hereinafter referred to as carts) four-axle and eight-axle wagons and more than the maximum distance between the bogies of eight-axle locomotives and four-axle locomotives. ” This statement is not true for four-axle cars of models 20-480, 12-4094, 20-4078, 20-9916-01 and for eight-axle cars of models 22-466, 22-4024, as well as for locomotives of the TG16 series. In the presence of the listed moving units in the train, the device described in the prototype will give a false result, and therefore cannot be used. In addition, the prototype does not allow the determination of moving units with three bogies, the production of which has been mastered recently.

The technical result of the claimed invention is to expand the functionality of the application of the method of forming an information model of a train moving along the control section of reading the parameters of the train, and increasing the reliability of its operation.

The claimed technical result is achieved by the fact that in the method of forming an information model of the train, including the use of a reading point of the train parameters, which include several control sections of the track, limited by reversible wheel sensors located along the train and connected to the corresponding inputs of the data processing unit analysis of the sequences of occupation and release of control plots by wheelsets of rolling stock, according to which о determine the belonging of each wheelset to one or another mobile unit, respectively, for each mobile unit that has passed through the reading point of the train parameters, the number of wheel pairs belonging to it is calculated, the base of the carts and the axial formula of the mobile unit are determined, which determine the type of each mobile unit - locomotive this or a car, according to the invention, at least three control sections of the track bounded by reversible wheel sensors are used: KU3, length 7600 mm, limited to quarters and the first taxiway, KU2, 3600 mm long, limited by the third and first taxiways, and KU1, 2600 mm long, limited by the second and first taxiways, while assigning the next serial number to the mobile unit, counting from the head of the train, take into account the number of its wheelsets , as well as the serial number of each wheel pair of this moving unit relative to the first wheel pair in a row from the head of the train.

The inventive method of forming an information model of a train is illustrated by the drawings shown in FIG. 12.

In FIG. 1 shows the placement of reversible rail wheel sensors and corresponding control sections of the track in the reading point of the train parameters. Three control sections of the KU3, KU2, KU1 path and four taxiways are used. The relative position and distance between the reversing wheel sensors along the train track is shown. All rail sensors are connected to the corresponding inputs of the data processing unit (not shown in the drawing).

In FIG. Figure 2 shows examples of the position of the wheelsets relative to RD1-RD4 at the time of confirmation of the fact that the reading point of the train parameters of the wagons with the wheel formula 2-2 (wagon with two trolleys on the right) (Fig. 2a) and 2-2-2 (wagon with three trolleys) (Fig. 2b).

Reversible wheel sensors of the train parameter reading point can be installed on one and / or two rail lines of one separately taken unbranched section of the track.

RD is connected to the corresponding inputs of the data processing unit (not shown in the drawing), which analyzes the sequence of occupation and the release of control sections by wheelsets of rolling stock.

According to the results of the analysis of the sequence of occupation and release by wheelsets of the corresponding control sections of the train parameters reading point and analysis of the number of axles (wheelsets) counted by the corresponding taxiways at the moment of leaving the next reading unit of the train parameters reading point for each moving unit:

- determine the serial number of this PE relative to the head of the train;

- calculate the number of KP belonging to this PE;

- determine the serial number of each CP of this PE relative to the first CP of the train;

- determine the base of the carts and the axial formula of PE;

- determine the type of each moving unit - a locomotive or a car.

The principle of operation of the proposed method for forming a model of a train passing through a point for reading train parameters is based on the following provisions.

When determining whether a control unit belongs to a particular control unit in the data processing unit, the following features of the relative position of the control unit in the existing fleet of railway control units are used:

a) the groups (carts) of the CP of each PE are located symmetrically with respect to the middle of the PE; accordingly, the number of the CP in any PE is always even;

b) within the same gearbox, the distance between gearbox groups (between gearboxes) is always greater than the distance between gearboxes within any gearbox group (hereinafter, the distance between gearboxes means the distance between gearbox axes).

The method for determining whether a gearbox belongs to one or another PE is based on the selection of PE carts based on their base using the control sections KU1, KU2 and KU3. At the same time, KU3 confirms the passage of a biaxial truck of any PE (locomotives, passenger, refrigerated and freight cars), KU2 - the passage of passenger, refrigerated and freight cars, and KU1 - the passage of trucks only of freight cars.

The data received from KU1-KU3 is not processed in real time, but after following all the train KP for RD1. Thus, it is possible to analyze the entire data array obtained in order to detect and correct errors that may occur, for example, due to malfunctioning of rail sensors.

The principles for determining whether gearboxes and carts belong to locomotives and wagons in the data processing unit are as follows.

All wagons with axial formulas 2-2, 2-2-2-2-2, 2-2-2-2-2-2-2, 2-2-2-2-2-2-2-2-2 have a base of bogies up to 2500 mm Therefore, to determine whether the KP belongs to wagons with the above axial formulas, it suffices to obtain data that KU1 (2600 mm long) was engaged and released twice in groups of two, three, four, six, or eight KPs that proceeded towards the pick-up and drop way. Conditions for determining the ownership of KP cars with axial formulas 2-2, 2-2-2-2-2, 2-2-2-2-2-2-2, 2-2-2-2-2-2-2-2-2 and 3- 3, 3-3-3-3 are shown in table 1.

To determine whether the gearbox belongs to cars of models 13-9851, 13-470-01, the following feature is used (Fig. 2): the distance between any adjacent groups of gearboxes of the above models of cars exceeds 10175 mm, which is more than the distance from the extreme gearbox of any of the cars of models 13 -9851, 13-470-01 to the nearest KP of any PE connected to this car (which is not more than 4766 mm). At the same time, the distance from the extreme gearbox of any of the cars of models 13-9851, 13-470-01 to the nearest gearbox of any control unit is less than the distance between the RD4 and RD1 sensors. When the CP of the previous PE leaves the point of reading the parameters of the train (KU1), KU3 is always occupied by the subsequent PE, unless the last PE of the train leaves the point of reading of parameters of the train.

Thus, the purpose of KU1-KU3 is as follows:

- KU1 (length 2600 mm), limited by RD2 and RD1, designed to perform the following functions:

a) determining the belonging of the wheel pairs to a mobile unit with biaxial carts, the base of which does not exceed 2600 mm, or a mobile unit with triaxial carts, in which the distance between any adjacent gearboxes does not exceed 2600 mm;

b) confirmation of the fact of the investigation as part of the train carriage with any of the axial formulas 2-2, 2-2-2-2-2, 2-2-2-2-2-2-2, 2-2-2-2-2-2-2- 2-2;

c) in cooperation with KU3-confirmation of the fact of the investigation of a freight wagon with any of axial formulas 3-3, 3-3-3-3-3 in the train;

d) in cooperation with KU3-confirmation of the investigation of any freight car with an axial formula 2-2-2 as part of the arriving train;

- KU2 (length 3600 mm), limited by RDZ and RD1, intended for:

a) interaction with KU1 in order to determine whether the gearbox belongs to cars with axial formula 3-3 (base of bogies 3400 mm or 3500 mm);

b) determining whether the gearbox belongs to locomotive carts with an axial formula of 2-2 or 2-2-2.

- KU3 (length 7600 mm), limited by RD4 and RD1, designed to interact with KU1 in order to determine whether the KP belongs to freight cars with an axial formula of 2-2-2.

The described method for the formation of an information model of a train moving through a train parameter reading point allows one to determine almost all types of PE in a train that are accessed on the road network of the Russian Federation - main locomotives, all existing types of cars with axial formula 2-2, 2-2-2, 2 -2-2-2, 2-2-2-2-2-2-2, 2-2-2-2-2-2-2-2-2, 3-3, 3-3-3-3.

At the same time as determining the type of moving units, the train parameter reading point determines the number of control units in each control unit and in the train as a whole. The number of gearboxes belonging to the whole train is determined by the number of gearboxes counted by rail sensors at the moment the train releases the reading point of the train parameters. The number of CPs belonging to each PE is determined by its axial formula. Moreover, the data from the taxiway is not processed in real time, but when the whole train leaves the reading point of the train parameters. The operation of the device is as follows.

While the train is traveling in the area within which the reading point of the train parameters is equipped, data is recorded and accumulated on the sequence of occupation and the release of control sections of the track from KU3 to KU1 and on the number of wheelsets that passed over the corresponding reversing wheel sensors during occupation and release of each from control plots. When the train leaves the area within which the reading point of the train parameters is equipped, the data processing unit starts analyzing the accumulated data in accordance with the above algorithms and forming the information model of the train.

The proposed method for the formation of the information model of the train does not provide for the measurement of interaxal distances in the PE. This ensures the independence of the results obtained from the speed of movement, it is possible to stop and temporarily change the direction of movement of the train during the passage of individual train units through the reading point of the train parameters. At the same time, the proposed method allows to identify almost all types of railway units operating on the network of main roads of the Russian Federation (that is, it has expanded functionality with respect to the prototype) in the train, using less equipment than in the prototype. Therefore, the method provides an increase in reliability.

Thus, the proposed solution has better characteristics than all known analogues and prototype.

Although the invention has been explained in detail using preferred embodiments, the invention is not limited to the disclosed examples, and those skilled in the art can partially change the sizes of said control sections of a track at a reading point of train parameters and their number without departing from the scope of protection of the described invention.
