Description

The invention relates to the field of railway automation and telemechanics, in particular to automatic locomotive signaling (ALS).

A known method of transmitting information to rolling stock [Kazakov AA, Kazakov EA Auto lock, locomotive alarm and hitchhiking. - M .: Transport, 1980, 360 pp.] (Pp. 29-30, Fig. 11, a) by means of a code-way transmitter with a continuously switched on motor.

The disadvantage of this method is that when following the short rail chains there are malfunctions in the ALS.

The closest in technical essence to the claimed method is the method selected as a prototype [Kazakov A.A., Kazakov E.A. Auto lock, locomotive alarm and hitchhiking. - M .: Transport, 1980, 360 pp.] (Pp. 267-270, Fig. 91), which is based on the translation of code pulses into a rail circuit from the moment it is occupied (from the moment the front contact of the track relay opens). The device, which is designed to implement the aforementioned method, contains a code-track transmitter (KPT) (in this example, two KPT: KT and KTK), an NGT relay relay, whose contact with the participation of the contacts of the track relays (NAP, 1-5SP, 11SP ...) code pulses of code current are transmitted to (station) rail circuits. The selection of codes (KZh, Zh, Z) is carried out by the contacts of the signal relays (Н1С, Н1ЛС). As a prototype of an electronic code-and-track transmitter (EKPT), a device was selected according to copyright certificate No. 1630944 [copyright certificate No. 1630944. Polevoy Yu.I., Alieva M.M., Kravtsova N.A. A device for transmitting information from the path to a locomotive was published on 02.28.1991. Bull. No. 8, 1991 IPC: B61L 3/20], the circuit of which contains a pulse sensor, first and second counters, four logical elements I.

The disadvantage of this method is that when following the short rail chains there are malfunctions in the ALS. The device selected as a prototype is designed to control the vigilance of the driver. Modification (changing the circuit and adding new elements) to the aforementioned device allows it to be used for a new purpose - to transmit ALS code current pulses in such a way as to exclude malfunctioning of locomotive devices when the train is traveling along short rail circuits.

The technical result, the achievement of which this invention is directed, is to increase the reliability of information transfer by eliminating malfunctions in the ALS during the movement of a moving unit on short rail chains.

The method consists in the fact that each rail circuit 1, 2, 3, and 4 (Fig. 1) receives code pulses from ECPT from zero cycle (Fig. 3). At the same time, in the locomotive decoder (the decoder in FIGS. 1, 2, 3 and 4 is not shown), all the counters come to a de-energized state regardless of the moment at which the train head left the previous RC relative to the code cycle. Therefore, when passing through an insulating junction, only one code cycle can be distorted instead of three, which can happen when using typical devices. In rail circuits 1, 2, 3 and 4 (Fig. 1), code current pulses are transmitted in the usual way due to the contacts of the track relays 7, 8, 9 and 10 by means of the contact of the relay relay 11. The new thing is that when the train enters the next RC when switching contacts 19, 20, 21 and 22 (FIG. 2), ECPT 14 is installed at the position at which the code pulses are transferred to the occupied RC from zero cycle (FIG. 3), i.e. from a long interval, which brings the scheme of locomotive devices to their original (for receiving a code cycle) state. This setting occurs because through the resistor 18 at the time of switching (the path relay anchor falls off) of the contacts (in the sequence 19, 20, 21, 22), the low potential is briefly applied to the input 2v of EKPT 14. The selection of codes З, Ж or КЖ is carried out by the contacts of the signal relays 23 and 24 in the usual way. Transmitter relay 15 with its contact 11 (figure 1) transmits to the RC 1, 2, 3 and 4 ALS codes.

The action of the device (figure 4) is that the sinusoidal voltage from the output of the transformer 26 controls the operation of the Schmidt trigger 27, from the output of which pulses with a period of 0.2 s are fed to the clock input of the first counter 28, this counter together with the logical element And 29 represent the divisor by 6 [Zeldin EA Digital integrated circuits in information-measuring equipment. L .: Energoatomizdat, 1986, 280 pp.] (Pp. 204-211). From the output of the logical element And 29 pulses with a period of 0.12 s are received at the clock input of the second counter 30, as well as at the second input of the reset counter 28 and reset it. Zeroing the counter 28 (input R '), the second counter 30 (input R') and the demultiplexer 32 (input VI) occurs when the train enters the rail circuits in the neck of the station when switching contacts 19, 20, 21 and 22 (at the time of de-energizing these relays due to the resistor 18). Therefore, the beginning of the translation of code pulses into these rail circuits begins at the beginning of the code cycle (in this case, the beginning of a long interval is taken as the beginning of the code cycle). The outputs of the counter 30, connected to the data inputs of the demultiplexer 32, allow you to get at the output of the demultiplexer 32 a position code with switching after 0.12 s. At the output of the logical element And 31 there are pulses for resetting the demultiplexer 32 through 1.68 s due to the fact that the elements 30 and 31 are a divisor by 14 [see Zeldin’s book there]. The inputs of the third, fourth and fifth logical elements AND 33, 34 and 35, respectively, are connected to the outputs of the demultiplexer 32 so that at the output of the element 33 appears the QOL code (two cycles), 34 - code 3, 35 - code G. The contacts of the signal relays 23 and 24 connect the outputs of the logic elements AND 33, 34 and 35 to the input of the amplifier 36 (the code cycle is selected), the output of which acts on the transmitter relay 15.

This invention will improve the reliability of information transfer by eliminating failures in the operation of the ALS when moving a moving unit along short rail chains.
