 A disadvantage of the known device is its inability to distinguish between the movement of a single shunting locomotive or the movement of a locomotive with wagons.

The aim of the invention is to expand the functionality of the device by fixing wagons coupled to a locomotive, which will increase the productivity of station workers by automating the generation of information on the performance of technological operations.

The essence of the invention lies in the fact that the known device for automatically determining the location and direction of movement of a shunting locomotive, which contains a transmitter mounted on the locomotive, and at the control point, a two-channel receiver that contains one and the other receiving coils connected respectively to the inputs of one and the other amplifiers, the outputs of which are connected to the inputs of the control unit for the presence of a transmitter signal, its output associated with the first input of the OR element, the output of which is connected to odes of resetting one and the other triggers, the unit inputs of which are connected to the outputs of the first and second pulse shapers, the other outputs of which are connected respectively with the first inputs of the first and second elements AND, the second inputs of which are connected respectively to the outputs of the second and first triggers and the outputs of the AND element are connected to the second inputs of the OR element, equipped with demodulators and additional pulse formers and AND elements, and the block for fixing the direction of movement is made with the input fixed single locomotive and the input of the fixation of the locomotive with the car, connected to the outputs of the third and fourth elements And connected to the third inputs of the OR element, the first inputs of which are connected respectively to the outputs of the second and first triggers, and the second inputs to the first outputs of the third and fourth pulse shapers, second the outputs of which are connected to the inputs of the first and second triggers, and the inputs, respectively, with the first outputs of the first and second demodulators, the inputs of which are connected to the outputs of the amplifiers, and first outputs to the inputs of the first and second pulse shaper, respectively, the transmitter contains a modulator, an antenna, an emitter-receiver of the ultrasonic signal and a threshold element, the input of which is connected to the output of the emitter-receiver of the ultrasonic signal, and the output to the input of the modulator, to the output of which the antenna is connected.

Comparative analysis with the prototype shows that the claimed device is characterized in that it contains a two-frequency transmitter, the modulator of which is controlled by a signal depending on

the locomotive is coupled to the car or not, and the receiver, including a demodulator, is used to generate a status signal of the moving locomotive: single or with the car.

Thus, the claimed device meets the criteria of the invention of novelty,

Comparison of the claimed solution with other technical solutions shows

that ultrasonic signal emitters, modulators and demodulators are widely known ..

However, when introduced in the indicated

In connection with the remaining elements of the circuit in the inventive device for automatically locating and directing the movement of the shunting locomotive, these blocks exhibit new properties, which expand the functionality of the device. This allows us to conclude that the technical solution meets the criterion of significant differences.

The drawing shows a functional diagram of the device.
