At the same time, the availability or absence of axle boxes on the wheel axle in no way affects the performance of the proposed device, which makes it possible to control the location of the wheel pair both inside and outside the car, including during its prevention or temporary storage.

A device for remote monitoring the location of the wheelset of a rail vehicle contains

identifier 1, indicated in the drawings by the positions of its constituent nodes; autonomous power supply 2; case 3 for their placement, indicated on the drawings by the positions of its constituent nodes.

Identifier 1 contains: a microcontroller 4, a navigation receiver 5 and a transceiver 6 located on a printed circuit board 7, interconnected by data exchange ports using printed conductors of a printed circuit board 7, which also has input terminals (not shown in the drawings) for connecting the conclusions of an autonomous source power 2 to the power ports of the microcontroller 4, navigation receiver 5 and transceiver 6.

The housing 3 is indicated in the drawings by the positions of its constituent nodes, and contains a base 8, a rotor 9, a first lock nut 10, a sleeve 11, a bearing 12, a second lock nut 13, a plate 14 and a casing 15.

In this case, the base 8 is made in the form of a metal disk with holes, which is fixed on the end face of the axis of the wheelset, parallel to its plane and coaxially with the longitudinal axis of its rotation.

The rotor 9 is inserted with its rod into the Central hole of the base 8 and secured to it using the first lock nut 10.

The sleeve 11 is mounted on the main rotor over the first lock nut 10 until it stops. The bearing 12 is mounted with its inner ring on the main rotor 9 over the sleeve 11 until it stops. The second lock nut 13 is screwed onto the rotor shaft 9 over the inner ring of the bearing 12 to a position where all the structural elements of the protective housing 3, mounted on the rotor shaft 9, are rigidly fixed to each other. The plate 14, made in the form of a metal disk with holes, is mounted through its central hole on the outer ring of the bearing 12 and rigidly fixed on it in parallel and coaxial to the base 8. The casing 15 of a translucent material in the form of a glass facing its cavity towards the base 8, has flanging along the edge of its side wall with holes through which it is attached to the base 8.

At the same time, the printed circuit board 7 with the microcontroller 4 installed on it, the navigation receiver 5 and the transceiver 6 is placed inside the casing 15 and mounted on the side of the plate 14 facing its bottom, and an autonomous power supply 2 is placed inside the casing 15 and is eccentrically mounted on the base 8 side of the plate 14.

The purpose of the components of the device.

Identifier 1 is intended for automatic remote identification (identification) of a wheelset with a specific serial number from many other wheelsets and registration of the geographical coordinates of its location.

The microcontroller 4 stores in its memory the identification (unique) data of the wheelset on which it is mounted, and also controls the operation of the navigation receiver 5 and transceiver 6. The navigation receiver 5 provides through the satellite (GLONAS / GPS) communication channel the reading of the geographical coordinates of its location, and as a result of this - reading the coordinates of the wheelset on which it is mounted.

The transceiver 6 implements a two-way GSM communication channel between the microcontroller 4 and the control center of the ground information service.

Autonomous power supply 2 provides electrical energy to all electronic components of the device and can be implemented either in the form of an energy storage device (ionistors, batteries, batteries), and can contain, in addition to an energy storage device, a converter of mechanical energy into electrical energy to recharge the energy storage device while driving couples.

The housing 3 is designed to accommodate the identifier 1 and an autonomous power supply 2 inside it in order to protect them from external mechanical and climatic influences, as well as to fasten the entire device to the end face of the wheel pair axis. In this case, the structural element of the housing 3, through which the entire device is mounted to the end face of the axle of the wheelset, is the base 8. And such structural elements of the housing 3 as: rotor 9, first lock nut 10, sleeve 11, bearing 12, second lock nut 13 - provide, on the one hand, fastening to the base 8 of the plate 14 with the identifier 1 and an autonomous power supply 2 placed on it, and on the other hand, provide a stationary, during rotation of the wheel pair axis, position of the identifier 1 and the autonomous source power supply 2. The casing 15 protects from the external influences the electronic components entering the device and critical structural elements.

Thus, the design of the housing 3 provides the ability to mount the proposed device on the end face of the axis of the wheelset, regardless of the presence or absence of axle boxes on it, and also eliminates the rotation of the identifier 1 and the stand-alone power source 2 during rotation of the end face of the axis of the wheelset, on which the proposed device It was found that improves the radio conditions of the identifier 1 and the ground control service.

It is the above-described design of the housing 3 with the electronic components located inside it: a microcontroller 4, a navigation receiver 5, a transceiver 6 and an autonomous power supply 2, made in the corresponding overall dimensions, which allows the device to be fixed on the end face of the wheelset axis, which allows remote control of the location of the wheelset pairs outside the wagon, outside the wagon, even when axle units are removed from the wheelset.

Preparing for work.

Before starting the operation of the device, the identification data of the wheelset on which this device will be installed must be loaded into the memory of the microcontroller 4, and the navigation receiver 5 and transceiver 6 must be initialized.

An autonomous power supply 2 must be prepared for operation.

After checking the data transmission channel between the control center and the microcontroller 4, as well as checking the receiving channel with the navigation receiver 5, the current coordinates of the location of the device, it can be installed on a pair of wheels.

Description of the operation of the device.

The device has two operating modes:

“Beacon” and “on-line”.

In the "beacon" mode, the microcontroller 4 with a specified frequency during tuning issues a command to the navigation receiver 5 to read the coordinates of the location of the wheelset. The microcontroller 4 stores the obtained coordinates in its memory, after which it activates the transceiver 6 and transmits the identification of the wheelset and the coordinates of the location of the wheelset received from the navigation receiver 5 to the control station.

The time interval between data transfer sessions can be changed by command from the dispatcher.

In the process of operation of the device in on-line mode, the microcontroller 4

performs the above operations only upon request from the dispatcher. In this mode, the energy of an autonomous power source is saved. The transition of the microcontroller 4 from one mode to another is carried out by command from the dispatcher.

Thus, the dispatching service has the ability to automatically remotely track the location of the wheelset both within the wagon and during the movement of the wheelset outside the wagon, outside the wagon, even if axle boxes are removed from its axis.
