Изобретение относитс к автоматической локомотивной сигнализации на железнодорожном транспорте.This invention relates to an automatic locomotive alarm system in railway transport.

Известно устройство локомотивной сигнализации, содержащее приемник, св занный через дешифратор числового кода с лампами локомотивного светофора 1} .A locomotive signaling device is known, comprising a receiver associated with a numeric code decoder with lamps of a locomotive traffic light 1}.

Недостатком этого устройства вл етс то, что при следовании поезда по зан тому или поврежденному блокучастку локомотиный приемник может воспринимать кодовый сигнал, который ложно извещает о свободное.-и и исправности рельсовой цепи блок-участка.A disadvantage of this device is that when a train travels over a occupied or damaged block station, the locomotive receiver can perceive a code signal that falsely notifies you of a free block circuit and the track circuit.

Цель изобретени - повышение надежности действи устройства.The purpose of the invention is to increase the reliability of the device.

Поставле. цель достигаетс тек, что устройство снабжено блоком контрол наличи кода, дешифратором контрольного сигнала, которые подключе- ны к выходу пpиeмниka, элементами НЕ и ИЛИ, блоком пам ти и двум ключевыми элементами, один из которых входом соединен с выходом приемника, а выходом - с дешифратором числового кода, выход красного огн которого соединен через элемент НЕ с входом одного элемента ИЛИ, другой вход которсЗГй подключен к инверсному выходуDelivered The goal is to achieve that the device is equipped with a code control unit, a pilot signal decoder, which are connected to the output of the receiver, elements NOT and OR, a memory unit and two key elements, one of which is connected to the output of the receiver, and output the decoder of the numeric code, the output of the red light of which is connected through the element NOT to the input of one element OR, the other entrance to which is connected to the inverse output

Claims

The locomotive signaling device consists of a receiver 1 connected to one key element 2, a decoder of the control signal 3 and a control unit for the presence of codes 4, while the output of the key element 2 is connected to the input of the decoder of the numeric code 5, and the output of the latter is connected through element 6 HE, with one element 7 OR, the output of which is connected to memory block 8, the output of memory block 8 is connected to another key element 9 and another element 10 30 OR, the output of which is connected to 11 red lights of the locomotive traffic light. The device works as follows. When the train passes by a prohibitive signal of a traveling light at a locomotive traffic light, a red light 1 lights up. When a train enters a busy or damaged section, there are no codes at receiver 1 Then a signal arrives at the inverse output of control code 4 outputs of one element 7 OR. The signal from the output of element 7 OR: is fed to the reset input of the block of 8 p. The signal from the output of the red fire of the decoder 5 of the numerical code is fed to the input of another key element 9, which is turned on, since its control input does not contain a signal from the output of memory block 8. The signal from the output of another key element 9 enters through the element OR GO to the red light lamp 11 and to the first control input of one key element 2 and turns off the last, thereby breaking the circuit between the output of receiver 1 and the decoder of the numeric code 5. Now the codes and in TC, the decoder 5 will not accept them. The switching of the decoder 5 of the numerical code from red light to the resolution indication occurs if, after the termination of the control signal, the code signal follows. If there is a control signal at the output of receiver 1, it is perceived by the decoder of control signal 3 and the control unit 4 for the presence of codes, as a result, the signal that blocks the memory block 8 is removed at the inverse of block 4. After the decoder 3 of the control signal decodes the incoming signal, a signal appears at its output that is stored in memory block 8. At the output of memory block B, a signal appears that turns off another Key element 9 and through the element OR 10 enters the red lamp 11. Turning off the key element 9 removes the signal from the control input of the key element 2, which turns on and prepares the decoder of the numeric code 5 to receive the code from the output of receiver 1. Information in memory block 8 with The signal remains as the signal is saved at the output of the red light of the decoder 5 of the numeric code until the decoder 5 switches to a more permitting indication, and there is no signal at the invarian output of the control unit 4, as the code signal immediately appears after the end of the control signal . After the decoder 5 of the numeric code switches, the signal from the red light output is removed, resulting in the output of the element NOT a signal appears, which through the element OR 7 clears the information in the memory block 8, which leads to the removal of the signal . our output, and this leads to turning off the red lamp 11 and turning on the key element 9. The signal at the output of the key element 9 is absent because it is absent at its input. If there is interference at the input of the receiver 1, which generates a control signal at its output, it also does not switch the decoder 5 of the numeric code, since after the interference stops, a pause is again formed, and the signal from the inverse output of the control code 4 resets in the memory block ti 8 falsely recorded control signal. The device improves the reliability of locomotive signaling when a train travels along a occupied or damaged section of a track circuit.
