The switch 14 (see, figure 4) has two multiplexer Ј 3 and 24 and the element 25 OR, and the block 15 has a switch 26, resistors 27 and 28 and multiplexer 29 o

The device works as follows.

On the section of the rail line 1, the length of which is determined by the span length between adjacent stations, sets of 2 track equipment are located. The distance between the adjacent sets of 2 track equipment is determined from the conditions of the worst resistance of the rail line ballast and can be, for example, 500-1000 m or any other distance.

The train, entering the section of the rail line 1, where sets of 2 track equipment are placed, shunts the rail line 1 with its first and subsequent wheel pairs, which in turn leads to turning off track receiver 3 "The signal from the output of off track receiver 3 goes to switch 4 and turns it off.

After turning off the track receiver 3, the positive edge of the signal from the t output of the inverter 16 acts on the counting input C of the D-flip-flop 17 and puts it in the zero state, with the log at the setup input S. Oh, i.e. the reset signal. from the D flip-flop 17 is cleared, and the input of the D signal is also a log.O. signal. This state of the signals is due to the fact that the inverse signal at the output of transceiver 7 determines the state of the track receiver of the adjacent rail line and is equal to the log. O, which corresponds to the enabled state of the track receiver of the adjacent rail line, the signal at the output b of transceiver 7 is equal to log 1, since i

central station block 15 is set to, for example, corresponding to the movement of trains from left to right, and at the entrance to the transceiver 10 there is a signal log „1,

But, considering that at the input g of block 4 there is a signal log. ABOUT,

the inputs S and D of the D-flip-flop 16 will also be the signals of the K-flip-flop logo in the switch, turning on in the zero state, becomes on the latch and with its direct output signal turns off the path generator 5 "

Since the movement of trains goes from right to right, the track receiver 3 can only be switched on from its own track generator 5, provided that the last wheel pair moves out of the zone affected by the first set 2 of track equipment. But track generator 5 will be turned on until the train (the head locomotive reaches the next set of track equipment and its wheel pairs, bypassing the rail line 1, turns off the track receiver of the next set 2 "The signal to turn off this receiver through the switch of its set goes to input d of the transceiver of this set and through the communication line 8 pa pas the input of the transceiver 10, where the corresponding block 11 is decoded and turned on, and the signal from the output of the block 11 (corresponding to the rail line section and to The package 2) goes to the switch 14, which switches the outputs of blocks 11 The outputs of blocks 1t, except for the output of one block 11, corresponding to the first traffic flow section of the rail line 1, are connected to the inputs of the multiplexer 23, one of which remains free and enters signal. Consequently, at the output of transceiver 7 and, respectively, at the input g of switch 4, a signal appears, 1 when the track receiver of the adjacent rail line is turned off.

This signal through its commutator and transceiver enters through the link 8 to the central post. There, this signal is decoded and from the output e to the address of the second rail line (output g) is recorded in the corresponding block 11, setting it to one state. Whitefish

From the output of this block 11 through the switch 14 enters on c. One and a transceiver 10 and further through the communication line 8 this information is transmitted to the first set 2. Here the information is deciphered by the transceiver 7 and the signal log. 1 from its output and enters the input r of switch 4. Thus, signals are passed to other sets 2. If the train leaves its zone of influence on set 2 of the first section with its wheel pairs, then generator 5 connects through the rail line 1 the receiver 3 of this set and feeds the departing train on the rail line 1, which, after the train leaves the rail track 1 to the second set 2 and its work zone, turns on the track receiver of the next set,

As soon as the track receiver 3 of the first set is turned on, the signal from its output is fed to the input of the element 19 of the switch 4 and at its output f the signal "log 1" appears, which is fed to the input of the trigger setup 17 through the element 18 OR and then to the input The transceiver 7. This information is transmitted to the central post and from the output of the transceiver 10 to the address (output g) sets the block 11, corresponding to the track set, to its initial state. At the central post, information appears that the train vacated the area

If the train is longer than the two sections of the rail line, determined by the distance between adjacent sets of track equipment, the first track receiver 3 is switched on with subsequent track receivers off simultaneously. But the first track receiver 3, as well as the subsequent ones, cannot be turned on until the next receiver is turned off in front of the lying section of the rail line. As soon as the train leaves the zone affected by the second set 2, the signal from the output of the generator 5 of the first set via the rail line 1 turns on the track receiver of the next section of the rail line in tbm case when the head entered the third zone. set 2.

The switching on and off of the track receivers is fixed at the central post and, according to their condition, the length of the train and the interval between the trains can be determined with the discreteness of the length of one section of the rail line between two sets of 2 "

Information from memory blocks 11 is fed to the inputs of block 13 and switch 14. In block 13, multiplexer 21 converts the parallel code into binary. The presence of a unit at the output of multiplexer 21 and depending on the number of polled address sets and sets 2 determines the interval between adjacent trains, namely, from the tail of the departing train to the head of the next train.

The polling of the transmit-receive blocks is cyclically sequential, and the polling direction is determined by blocks 13 and 12.

A survey of sets 2 goes in the opposite direction with respect to train movement, for example, the binary code 1000 at the exit of the trigger counter 22 determines the QOL code (red and yellow) and indicates that between the tail of the departing train and the respondent set 2 there is only one rail segment line0 This information is transmitted to the specified polling address via the transceiver 10 and the communication line to the corresponding set 2 in the code generation unit 6, which acts on the getter 5, which issues a signal line to the rail line 1 to code with QOL.

Similarly, other codes are formed when polling sets 2 "
