На чертеже показана структурная схема устройства.The drawing shows a structural diagram of a device.

Устройство состоит из генератора высокой частоты 1, подключенного параллельно к рельсам 2, трансформатора синхронизации 3, конденсатора 4, фазового детектора 5, приемных катушек б и 7, исполнительного блока 8.The device consists of a high-frequency generator 1 connected in parallel to the rails 2, a synchronization transformer 3, a capacitor 4, a phase detector 5, receiving coils b and 7, an executive unit 8.

Устройство работает следующим образом.The device operates as follows.

Генератор высокой частоты 1, подключенный параллельно к рельсам 2, вырабатывает синусоидальный сигнал. В цепь генератора трансформатора высокой частоты последовательно включен и конденсатор 4. На выходе трансформатора синхронизации. 3 выделяется опорный сигнал, который подается на вход синхроканала фазового детектора 5. При отсутствии рельсового транспортного объекта в зоне чувствительности устройства на вход информационного канала фазового детектора 5 сигнал не поступает, так как приемные катушки 6 и 7 включены встречно.The high-frequency generator 1, connected in parallel to the rails 2, produces a sinusoidal signal. A capacitor 4 is also connected in series to the generator circuit of the high-frequency transformer. At the output of the synchronization transformer. 3, the reference signal is allocated, which is fed to the input of the synchro channel of the phase detector 5. In the absence of a rail transport object in the sensitivity zone of the device, the signal does not arrive at the input of the information channel of the phase detector 5, since the receiving coils 6 and 7 are turned on in the opposite direction.

При шунтировании колесными парами рельсов 2 со стороны одной из приемных катушек, например катушки 6, на выходе фазового детектора 5 появляется сигнал, фаза которого соответствует принятому направлению движения поезда. При проезде колесной пары j точки подключения генератора высокой частоты 1 фаза сигнала на входе информационного канала фазового детектора 5 меняется на 180°, чем достигается фиксация каждой оси поезда.When wheel pairs of rails 2 are shunted from one of the receiving coils, for example, coil 6, a signal appears at the output of the phase detector 5, the phase of which corresponds to the accepted direction of train movement. When passing a pair of wheels j of the connection point of the high-frequency generator 1, the phase of the signal at the input of the information channel of the phase detector 5 changes by 180 °, thereby achieving fixation of each axis of the train.

Предлагаемое устройство позволяет Определить направление движения поезда за счет сравнения амплитуды сигнала Синхросигнала и информационного сигнала, определить расстояние от точки установки устройства до места нахождения рельсового транспортного объекта и скорость его движения за счет определения скорости изменения амплитуды информационного сигнала.The proposed device allows you to determine the direction of movement of the train by comparing the amplitude of the clock signal and the information signal, to determine the distance from the installation point of the device to the location of the rail transport object and its speed by determining the rate of change of the amplitude of the information signal.
