The invention relates to railway automation and signaling devices and can be used to transmit warning information when approaching and passing by train a traffic light zone with a prohibition signal.

A device is known for transmitting traffic signal information to a locomotive, comprising an encoder, the input of which is connected to the contacts of the signal relays, and the output is connected to a transmitter.

A disadvantage of the known solution is the low reliability due to the impossibility of transmitting information from the train to the locomotive about the approach of the train to the zone of the traffic light with the inhibit signal, and if it passes, the signal is transmitted to force the train to stop.

The aim of the invention is to increase reliability.

  This object is achieved by the fact that the known device is equipped with proximity sensors, trains and an additional transmitter installed along the rails, with the first transmitter having two and the second with one blocking inputs, the first blocking inputs of the transmitters being connected to the proximity sensors of the train, the second blocking input of the first the transmitter is connected to the output of the second sensor, and the information inputs of the transmitters are connected to the output of the encoder, in addition, as the output load of the first sensor and the output hydrochloric load the first transmitter and the second sensor input load and output load of the second transmitter used capacitances of the first and second wires with respect to ground, disposable zones prosledovani trains.

The drawing shows a functional diagram of the proposed device.

The device contains contacts of a signal relay 1 connected to the input of encoder 2, a first train proximity sensor 3 connected to the first blocking input of the first transmitter 4, and also a second proximity sensor 5, connected to the blocking input of the transmitter 6. The output of the second proximity sensor is connected in addition to the second blocking input of the first transmitter 4, and the information inputs of the first 4 and second 6 transmitters are connected to the output of encoder 2. The loads of the first 3 proximity sensors and the first transmitter 4 as well as the second proximity sensor 5 and the second transmitter 6 are electric. capacity 7 and 8, respectively, which are formed by the first and second wires located in the areas of the train.

The proposed device works

in the following way.

In the initial state, from the contacts of the signal relays 1, through the encoder 2, a zero signal arrives at the information inputs of the first 4 and second 6 transmitters, corresponding to the resolving signal of the traffic light. The first 3 and second 5 sensors of the proximity of the train to the inputs of which are connected capacitances 7 and 8 of the wires located in the zones of the train,

5 are characterized by states when zero signals are received from their outputs to the first blocking inputs of the transmitters (as well as to their information ones). At the same time, the second blocking input of the first transmitter 4 also contains a zero signal from the output of the second proximity sensor 5.

During its movement, train 9 will sequentially follow the zones of the first 3 and second 5 of the proximity sensors, causing their triggering due to changes in the capacitances 7 and 8. But since a zero signal will be present at the information inputs of the transmitters at that time, sorting the resolving signal of the traffic light, the appearance of single signals from triggered proximity sensors fixing the appearance of the train at the first blocking inputs of the transmitters

5 will enable transmitters to transmit information to the locomotive about the location of the train. This situation is normal when the traffic light permits.

0 If the traffic signal is prohibitory, then from the contacts of the signal relays 1 through the encoder 2 to the information inputs of the transmitters 4 and b will receive a single signal, which is enable

5 to turn on the transmitters when a train 9 is detected in the zones of proximity sensors. Now, when a train appears in the zone of the first proximity sensor 3, the value of capacitance 7 will change and the triggered sensor will turn on the first transmitter 4 to transmit warning information with its output signal to the locomotive, through the load capacitance 7 of the wire to provide operational braking. If for some reason, train 9, following the zone of the first 3 proximity sensors, finds itself in the zone of the second 5 proximity sensors, then the last one. Having worked due to a change in the capacitance 8. with its output signal, it will turn off the first 4 and turn on the second 6 transmitters. In this case, the emergency brake signal of the transmitters 6 is transmitted through the load capacitance 8 of the second

wires. Thus, the formation and transmission of this or that information from the path to the locomotive when a train is being passed through the zones of proximity sensors is carried out only with a prohibiting traffic signal.

the transmitters are made with two blocking inputs, while the first blocking inputs of the transmitters are connected to the proximity sensors of the train, the second blocking input of the first transmitter is connected to the output of the second transmitter, the first blocking input of which is connected to the output of the first transmitter, and the information input is to the output of the encoder.
