Description

. The invention relates to the field of railway automation and can be used for interval control of train traffic.

A three-digit auto-lock is known, comprising a rail and a linear circuit, a control circuit and a traffic light control. A disadvantage of the known device is the insufficient importance of traffic lights in conditions of increasing intensity.

The closest in technical essence to the claimed device is a four-digit auto-lock, selected as a prototype, comprising a linear and rail circuit, a circuit for switching on traffic lights and a transmitter relay.

The disadvantages of the known auto-lock are as follows.

In the linear circuit, relays of the second reliability class (combined relay), linear transformers are used, which reduces the safety and reliability of the automatic blocking action.

The burnout of the green lamp, if the yellow lamp does not light, leads to the extinguishment of the traffic light and the inclusion of yellow from the previous traffic light; The burning of a yellow fire lamp leads to the same consequences.

The purpose of the invention is to increase the reliability of the auto-lock action.

The indicated goal is achieved by that. that there is a four-digit auto-lock containing a linear relay, the winding of which is connected to the front contacts of the track relay, signal relays, green and yellow fires, the windings of which are connected to the first and second contacts of the linear relay, DC and AC sources, fire relays of green, yellow and red lights, equipped with additional fire relays for yellow and red lights, diodes and an additional linear relay, one of the winding terminals of which is connected to one of the winding terminals of the first linear relay, and the other terminal connected to one of the front-line contact track

Figure 5 presents the wiring diagram 1 of the transmitter relay 25, which is energized from the poles 13 and 14 and passes

through one of the contacts (24.1, 24.2, 24.3) of the code-way transmitter 2.4, and the circuit is selected by the contacts of the fire relays 8.6, 9.7, 10.5; 11.4 and 12.3. The device operates as follows. Through linear wires (L, OL in Fig. 2), information is received in the relay cabinet of the traffic light 2.1 (see Figs. 1 and 2) about the freeness of the front lying area. If the section is occupied at traffic light 2, then both line relays 4 and 5 are de-energized due to contacts 2.3.1 and 2.3.2 (Fig. 2). With the free state of one in front of the lying section and the whole filament of red fire is excited

5 minus linear relay 4 through the front (Ф) contacts of the track relay 2.3.1 and 2.3.2, the rear (T) contacts of the fire relay of green fire 8 L and 8.2, the rear contacts of the fire relay of yellow and reserve yellow fire 9.1

0 and 9.2,10.1 and 10.2, as well as front contacts of the fire relay of red OM 11.1 and 11.2 or 12.1 and 12: 2. With two free ahead lying block sections excited positive linear relay 5, through the front

5 contacts of the path relay 2.3.1 and 2.3.2, then the contacts of the green fire relay 8.1 and 8.2, the contacts of the yellow fire relay 9.1 and 92, and when the yellow lamp lamp burns out, the relay 5 is excited through the front contacts of the backup yellow fire relay 10.1 and 10.2. With the three forward sections free from alternating current (poles 15 and 16), both linear ones are excited. relays 4 and 5 through the front contacts of the track relay 2.3.1 and 2.3.2 and the green fire relay 8.1 and 8.2. When the green fire lamp burns out, the green fire relay 8 turns off and, with its contacts 8.1 and 8.2, switches the power supply circuit of the linear relays to the contacts

0 9.1 and 9.2 of the yellow fire relay 9, which is energized after the yellow signal relay 20 is energized through its contacts 20.2 and 20.3 (Fig. 4). The signal relay 20 is activated due to the fall of the core

5 relays 8.3 (fig.Z). Turning off the fire relay 9 when the yellow lamp 23.2 burns out, but the backup yellow lamp 23.1 is in good condition (relay 10 energized) does not lead to a change in the state of the linear relays.

0 since their circuit passes through the contacts 10.1 and 10.2 of the fire relay of the yellow backup lamp 10. If both yellow fire lamps burn out, but with a working red fire lamp, relay 5 is de-energized and the relay is activated

5 4 since the line circuit is supplied with reverse polarity current through the terminals 11.1 and 11.2 of the red fire relay. When the main thread of the red lamp 23.3 burns out, the fire relay 11 is de-energized, but relay 12 (with a working reserve thread

23.4) it maintains the relay 4 circuit with its front contacts 12.1 and 12.2. In the event of the burnout of both red lamps, the linear relays 4 and 5 are de-energized. The operation of the signal relays 19 and 20 (Fig. 3) is carried out as follows. If the section behind the signal is occupied, then both line relays 4 and 5 are de-energized and their contacts 4.1 and 5.3 exclude the excitation of both signal relays 19 and 20. If one front section is free and at least one thread of the red lamp in front of the lying signal is intact, then only the linear relay 4 is activated (Fig. 2) and through its front 4.1 and rear contact 5.2 a signal relay circuit 20 is formed. If two front sections are free and the traffic lights in front are operational, then the linear relay 5 (Fig. 2) is activated and front contact 5 3 creates a circuit for the signal relay 20, a yellow lamp circuit 23.2 is created through its contacts 20.2 and 20.3 and a relay 9 is activated (Fig. 3), which, by its contact 9.3, creates a circuit of the signal relay 19 (Fig. 3) by means of the front contacts 5.1 and 5.2. At the same time, the Green light 23.5 (Fig. 4) lights up, through the contacts 19.1 and 19.2, and the green light relay 8 is energized. If there are three free sections, then both linear relays 4 and 5 (Fig. 2) are activated and their with contacts 4.1 and 5.2 you create / The circuit of the signal relay 19 (FIG. 3), which with its contacts 19.1 and 19.2 creates the circuit of the green lamp 23.5 (FIG. 4) and the fire relay 8. The contact of the fire relay 8.3 (FIG. 3) in the circuit the signal relay 20 ensures that the yellow light is switched on at the traffic light of the lamp when the green lamp burns out. Simultaneous burning of the yellow and green fire lamp (two block sections are free) is possible only with a working main thread of the yellow fire lamp. This is necessary because the ripvi burning green fire lamp (main thread: visibility 1000 m) and the backup filament of the yellow fire lamp (visibility less than 1000 m) the driver will initially see only the green light of the traffic light, which can cause a dangerous situation. To eliminate this situation, only the contact 9.3 of the fire relay 9 is entered into the excitation circuit of the signal relay 19 (when the two block sections are free), and the contact of the fire relay of the backup yellow fire 10 is missing in the relay circuit 19. Turning on the traffic light lamp 23 (Fig. 4) is carried out by the contacts of the signal relays: green light 19.1 and 19.2 (green lamp 23.5 and green fire relay 8), yellow light 20.1,20.2 and IZ.Z (the main and reserve threads of the yellow lamp 23.1 and 23.2 , fire relays 9 and. 10). as well as contacts of fire relays 8,9,10,11. The backup yellow lamp lamp thread is only activated if the yellow lamp alarm relay 20 (20.1 and 20.3) is energized and burns out.

the main thread of the yellow lamp. The integrity control circuit of the main and backup filaments of a red fire lamp, unlike yellow, provides control of both filaments both in cold and in heated state. The cold threads of the red lamp are monitored when at least one green or yellow light relay is activated (contacts 10.3 and 10.4.9.5 and 9.6.8.4 and 8.5). Turning on the main thread of the red lamp

5 fire occurs when the fire relays 8, 9 and 10 are de-energized. In this case, contacts 8.4 and 8.5,9.5 and 9.6,10.3 and 10.4 switch the lamp circuit with the high-resistance winding of the fire relay 11 (top according to the diagram)

0 to low resistance. If the main thread of red fire burns out, the fire relay 11 is de-energized and, with its contact 11.3, switches the backup red lamp circuit 23.4 from the high-resistance coil of relay 12 (top 5 according to the circuit) to low resistance (lower by circuit). The transmitter relay circuit 25 (figure 5) includes the contacts of all fire relays. This ensures full correspondence between the actual reading.

0 signal and rail code. An exception is the case when the green and yellow lights are lit at the traffic lights, and the green light code is transmitted to the rail circuit (as in the existing auto-lock).

5 The coding of the rail circuit is terminated when both..buttons of the red lamp burn out when a red light is lit at the traffic light. The generation of code pulses (as in the current auto-lock) is carried out by the contacts of the code-way transmitter, 24.2, 24.3. The contacts of all fire relays are switched on.
