(54) DEVICE FOR AUTOMATIC LOCOMOTIVE ALARM

one

The invention relates to automation and remote control devices in railway transport.

A device for automatic locomotive signaling is known, comprising a receiver installed on the locomotive with locomotive coils connected to it, connected to the receiver blocks for selecting an odd and even block sections, a device controlling the health of the device elements, one of the inputs of which is connected to the output of the decoder, and output through a logic processing unit an execution unit, a switching unit, the inputs of which are connected to the allocation blocks of an odd and even block 1 feature.

A disadvantage of the known device is the low reliability of the shunt and control mode for the locomotive receiver.

The purpose of the invention is to increase the reliability of the device in operation.

The goal is achieved by the fact that the device is equipped with a unit for registering the codes of availability and operability of the track circuit, the input of which is connected to the output of the decoder.

and the output - to the switching unit and to the control unit of the health of the elements of the device. The drawing shows the functional diagram of the device.

On the locomotive, the receiving coils 1 are connected to the receiver 2, the output of which is connected to the inputs of blocks 3 and 4 of the extraction, respectively, of an odd and even block-sections and decoder 5. The output of which is connected to the registration block 6

to codes of availability and health of the track circuit, the unit 7 of the control of the health of the device elements and with one input of the logical processing unit 8, the other forbidden input of which is connected to the output of the unit 7, and the third control input to

15 output unit 9 switching. The inputs of the block 9 are connected to the outputs of blocks 3 and 4 and block 6. The output of block 6 is also connected to another input of block 7. The outputs of block 8 are connected to the input of the execution unit 10.

20In the characteristics of an odd and even block, any signals that have any known difference in their qualitative characteristics can be used.

The device works as follows.

The code signals are perceived by the receiving coils 1 and fed to receiver 2. At the output of receiver 2, blocks 3 and 4 of the selection of odd and even block sections and a decoder 5 are turned on. When the locomotive is on an even block section, the signal will be at the output of block 4, and at the output block 3, the signal will be absent. The change of signals at the outputs of these blocks occurs when the locomotive switches from one block to another. The decoder 5 decodes the signals received at the locomotive by the automatic locomotive signaling system (ALS) from the path and, based on the received information, issues commands to the executive unit 10, i.e., to turn on the lights of the locomotive traffic light. The output of the decoder 5 affects the block 6 registration codes of the availability and health of the track circuit of the next block section, which records the reception of such codes, as well as the block 7 of the control of health and the input of the block 8 logical processing. The signal at the output of block 6 will be only in the case of reception of codes of availability and health of the track circuit. This signal acts on the other input of block 7 and on one of the outputs of block 9, the other inputs of which are connected to the outputs of blocks 3 and 4. Block 9 checks for one of the signs when the train is moving through the block section, the presence or absence of free codes and good health the next block before the change of the sign and fixes the moment when the locomotive enters the next block along the movement. If there was no signal at the output of block 6 before the moment of the change or absence of both signs, i.e., the codes corresponding to the freeness of the next block section with an intact rail thread were not accepted, in order to exclude the possibility of non-fulfillment of the shunt and control modes at the locomotive receiver and To ensure complete safety of the traffic in this situation, the input of block 8 from the output of block 9 is given a signal which is fed to the input of the executive unit 10, which causes the appearance of a prohibitive indication at the locomotive traffic light and incorporating brake control components (not shown). Regardless of the codes received, prohibiting

the indication at the locomotive traffic light will be until the locomotive enters the first free block with a good rail track in the course of the movement. In this case, until the moment of changing the sign, a signal will be present at the output of block 6, which means that the train enters the free block section with an intact rail thread, therefore the signal from the control input of block 8 will be removed and the signal arriving at block 9, will impact

on the executive unit 10, and the locomotive equipment ALS will function in the usual way. At the locomotive traffic light, according to a Vits, a signal indication corresponding to the received ALS code

out of the way. Such a state of the circuit will be maintained until the train enters a occupied block section or a block section with a damaged rail thread, except in the case where the signal from the output of the control unit 7 to the input of the block 8 arrives. As a result, locomotive traffic lights also have a prohibitory indication that will remain until the fault is eliminated.
