Description

The invention relates to railway automation devices that provide interval control and traffic safety, as well as an increase in the capacity of railway lines and subways. The purpose of the invention is to increase the amount of information transmitted. FIG. I is a schematic diagram of the proposed device; Fig. 2 is a schematic diagram of the control relay connection. The device contains sections 1 of rail lines with track relay 7 with contacts 7.1 and 7.2, track relay 8 with contacts 8.1-8.5, track relay 9 with contacts 9.1-9.5, track relay 10 with contacts 10.1-10.4, and track relay 11 with contacts 11.1 and 1.2 and track relay 12 with pin 2.1. Each S EST contains one control relay with contact I3, a second control relay with contact 14, a third control relay 15 with contact 15.1, a fourth control relay with contact 16, and a single separation relay with contacts 17 and 18, a second separation relay 19 ci contacts 19.1-19.3, the third separation relay with contacts 20 and 2 and the fourth separation relay with contact 22. Code signal generators 23-26 are installed for signal transmission. The device works as follows. In the initial position, the track relays 8 and 9 are de-energized, while the remaining track relays 7, 10 and 11, 12 are energized. The control relays of sections 1 and 2 are de-energized, and sections 3 and 4 are closed. Such a state of control relays corresponds, for example, to their inclusion to provide automatic control during interval control of train movement. The isolation relays of all sections, except section 3, occupied by the tail of the train, are energized. At the same time, the dividing relays of the free sections receive power through the closed front contacts of the traveling relays of their sections, and the second separating relay 19 of the section 3, which is occupied by the train’s head, is self-locking along a circuit including its own front contact 19.2 and a round contact 8.4 44 of the traveling relay 8 of the previous leg 2, occupied by train. It should be noted that in the case of the train occupying several sections, the separation relays of all these sections, except the section occupied by the tail of the train, will also be under current. The isolating relay of section 2 occupied by the train's tail is de-energized, since both parallel circuits of its power supply are open, and this relay is removed from self-locking when the rear contact of track relay 7 is opened at the moment of release of the section by the tail of the train. Thus, each separation relay in its de-energized state determines the occupation of the corresponding section by the tail of the train, i.e. fixes the location of the tail of the train. By their front contacts, the separating relays separate the switching circuits of the code signal generator, limiting the flow of signal current to the rail lines of sections behind the tail of the train. In the specified position of the train, the signal current can be transmitted to the rail line occupied by the tail of the train only from the generator 23 of code signals, since the generators 21 and 22 of the code signals are disconnected by the front contacts 8.1 and 9.1 of the traveling relays 8 and 9 of sections 2 and 3, charged 24 signals and the generator is disconnected by the rear contact 10.2 of the track relay of its section 4 and the rear contacts of the track relay of the section 3 in the same way as the generator of 25 code signals is disconnected from section 4 and all subsequent contacts 10.4 and 10.2 of the relay relay 10 4. The signal current of the generator 25 of the code signals of this section 3 enters the rail line from the input end of the previous section, occupied by the train tail, through the front contact 10.1 by the relay 10 of the next section 4, the front contact 15.1 of the third control relay 15 of this section 3, front contact 20 of the third separation relay of the next section 4, tishovaya contact 8.2 of the track relay 8 of the previous section 2, front contact 19.1 of the second separation relay 19 given3

area 3, front contact

7.1 track relay 7 of the first free train behind the train of section 1 and rear contact 8.5 of the track relay 8 of the previous section 2. Thus, to transmit the control signal, the code signal generator belonging to the section occupied by the train head is automatically selected.

Suppose that as the train progresses, its next segment U will be taken up with its head, while section 2 will still be occupied by the tail of the train. In this case, the front contact 10.1 of the de-energized track relay 10 will turn off the generator 25 of code signals, and the rear contact 10.2 of this relay 10 will connect the generator 26 of code signals corresponding to section 4 to the signal transmission circuit. The state of the rest of the circuit does not change, while the rear contact

The 9.2-track relay 9 of section 3, occupied by the train and now adjacently adjacent, occupied by the sections, provides the translation of the code signal from that part of the common circuit that determines the location of the train head, i.e. that part of the common chain that locates the tail of the train. If the train occupied at the same time more than three sections, regardless of the number of these sections, the code signal would be transmitted in the specified order through sequentially connected rear contacts of the track relays of sections located between the sections occupied by the head and tail of the train.

Similarly, the transfer takes place when the train occupies only one section of the rail line.

In the case of a surge in one train to another, the inducing train cannot receive a code signal intended for 13444

of the signal train, as the translation signal of the code signal will be open by the front contact of the separation relay of the section occupied by the tail of the charge train. For example, when a train rises in the position indicated in FIG. 1 position by another train, even in the case when the tail of the catching train is located within

Q.Part 1, open front contact 17 of the first separating relay of section 2 ensures that the input end of section 1 is disconnected from the generator 25 of code signals. The transmission of the code signal to the tail of the injected train can be preserved due to the presence of a closed circuit passing through the contact 7.1 of the track 7 of section 1, occupied

Q by the charging train, and the rear contact 18 of the first isolating relay of section 2, occupied by the tail of the charging train.

In the event of a train stopping and then rolling up, the device stops transmitting control signals to the train.

If it is necessary to withdraw a train that is out of control, the train in the back approaches and connects with the train that has stopped. When, after moving the coupled trains, the tail of the convoy enters the boundaries of the section that was previously occupied by the tail of the train, it lost

5 th control, in the tail of the output. the train begins to receive control code signals on the order considered above as a single train. Technical and economic effect

0 of the proposed device is achieved by increasing the amount of information transmitted, increasing safety when rolling up the train, and in the case of withdrawing a train that has lost control from the line.
