Description

The invention relates to the field of railway automation and telemechanics and can be used in interval control systems for train movements and in various electrical centralization systems to prevent rolling stock collisions at stations.

There are known systems of automatic locomotive signaling, the operation of which is based on the use of digital coding of information in the radio communication system of locomotive devices with stationary ones, and both rail circuits and local (point) channels and a satellite navigation system are used to determine the locations of moving units (see Zorin V .I., Shukhina EE Traffic safety system for special self-propelled rolling stock. "Automation, communications, informatics", No. 4, 2000, p. 38-43).

A known system containing elements of the interface of this system with EC devices (a polling controller for recording data on the status of EC actuating devices in the station driver, a matching device, etc.), equipment for receiving and transmitting radio commands, an on-board controller, into which the driver enters the required through the control unit teams and to which routing tasks are received via a radio channel from stationary devices. In this case, it is assumed that both the driver and the chipboard are loaded with additional operator functions (see Kochnev A.V. Shunting automatic locomotive signaling. "Automation, communication, computer science", No. 4, 2000, p. 43 ... 47).

In known devices, the switching of locomotive ALS devices to different modes is performed by the driver, which, in the absence of objective control of such actions by the driver, does not exclude collisions of rolling stock and, compared with the automatic control of the process of switching modes, reduces traffic safety. In addition, these devices involve the use of relatively sophisticated equipment of both locomotive and stationary automation devices, which increases the cost of the system and eliminates the forced widespread introduction of such devices throughout the Russian railway network.

Closest to the invention in technical essence is a system containing stationary (track) and locomotive devices of automatic continuous locomotive signaling (ALSN) (see Vakhnin MI, Ilyenkov VI, Kotlyarenko NF, Shishlyakov A. B. "Track lock and auto-adjustment" Transport, M., 1966, p. 292-321).

The main disadvantage of the known system is the lack of elements in it to automatically switch the track locomotive devices of the ALS from the mode that allows, after stopping, to follow the closed traffic light on the stage with reduced speed, to the station mode of operation of the ALS, which absolutely excludes the movement of rolling stock along those station sections of the track that are protected closed station traffic lights (entrance, route, weekend in train movements or shunting in shunting movements niyah).

Since not all locomotives and not all stations are equipped with SAUT devices, there is a danger of a train entering the station under a prohibiting signal indication of the input traffic light, as well as unauthorized tracking of rolling stock for a closed output or shunting traffic light. The inventive system is aimed at eliminating collisions of rolling stock by eliminating unauthorized access to a closed station traffic light.

The technical result to which the invention is directed is to expand the functionality of the ALS system, increase the operability of the ALS-machinist-DSP system, and enhance traffic safety by preventing collisions of rolling stock during shunting and train movements.

The technical result is achieved by the fact that in a system for receiving information on a locomotive to prevent a collision of rolling stock at a station, which contains EC devices in stationary equipment and a standard code signal generator, connected via code selection elements to a transmitter relay, through the front contact of which a code transformer is connected with the rail line of the approach section, and in locomotive equipment - receiving coils, a speed meter with an overspeed control contact, a tofor, a code signal amplifier with a pulse relay, the switching contact of which is connected to the pole of the locomotive power supply, and the front and rear contacts are connected to the counting group of the decoder relay, which contains the counting and signal groups of the relay, the correspondence relay and its repeater, the speed monitoring relay with control bodies associated with the contacts of the speedometer, the decoder connected via the electro-pneumatic valve to the braking means of the locomotive (train) is supplemented with fixed definition in stationary equipment the locator of the code signal connection to the rail line, connected through the switching front and rear contacts of the transmitter relay with a code transformer, the first and second outputs of the said track identifier are connected to the output end of the corresponding rail threads of the rail line of the approximation section, the third and fourth outputs of the track identifier are connected to corresponding rail yarns of the rail line of the approach section at the calculated distance from the closed station traffic light, s which the train approaches, and the fifth and sixth outputs of the track identifier are connected to the mentioned rail line to one rail line, respectively, at the output end of the standard code signal “kzh” pickup zone and the input end of the non-encoded section of the rail line with the closed track station traffic light, and introduced into the locomotive equipment additional sound annunciator of alarm, optical annunciator of enhanced vigilance, matching unit containing a determinant of reception from the path of standard code signals "KZh", a receiving signal from the path of inverse code signals “KZh”, a converter of inverse code signals “KZh” to standard code signals “KZh” and a relay for controlling the yellow-red signal indication at the locomotive traffic light, the matching unit being included in the section of two wires connecting the amplifier to the decoder , and has not only a connection with the speed meter and traffic light, but also is equipped with a memory element about receiving the standard code signal “KZh” from the path, while the front contact of the reception detector relay is from the path of the standard code signal “KZh” for it is connected in series with the speedometer over speed control contact, and the front contact of the reception detector relay from the inverse code signal path “KZh” is connected in series with the optical alertness detector and an additional audible alarm detector.

A significant difference of the invention is the totality of the connections between the elements newly introduced into it, linked to the EC devices, as well as the presence of new devices and elements in it: track determinants of the connection of standard code signals “KZh” and inverse code signals “KZh” to the rail line while maintaining non-encoded section of the rail line during the rapprochement of the train (train) with a closed track station traffic light, matching unit containing a relay for controlling the yellow-red signal indication to the locomotive traffic lights, elements for switching on an additional audible alarm annunciator and an optical alert intensifier, determinants of reception from the path of standard and inverse code signals “KZh” with a converter of inverse code signals to standard ones, memory of receiving from the path of standard code signals “KZh” and introduction to the circuit connecting the decoder with the speed meter, the front contact of the relay of the determinant of inverse code signals "KZh".

Only these differences provide higher traffic safety, improve the working culture and life safety of drivers and particle boards, expand the functionality of the interval control system for train movements, and eliminate rolling stock collisions during shunting and train movements.

The system operates as follows. When the train 1 enters the traffic light 2 and when the station traffic light is closed (for example, with a red signal indication at the input traffic light 4, when contacts 6.1.3., 6.2.4., 6.1.5., 6.2.2 are closed in the directional determinant 5 ., 6.1.4., 6.2.5., 6.2.6. And 6.1.6 of the corresponding relays) the rail line of the approaching area within the area of zone 3.1. encoded with the standard code signal "KZh" (see the third 5.3. and the fourth 5.4. outputs of the track identifier 5), and within the zone 3.2. the inverse code signal “KZh” is valid (see fifth 5.5. and sixth 5.6. outputs of the track identifier 5); zone 3.3. it is not encoded. After the entry of the front wheelsets 1.1. trains 1 to zone 3.1. excited on the locomotive in block 11 of the relay 16 and relay 22 of the determinant 17 of the standard code signal "KZh"; at the traffic light 14, the yellow-red signal of the lamp 14.3 is turned on. The relay 20 of the determinant 18, receiving in its windings only short-term current pulses of the standard code signal "KZh", remains unexcited.

After the entry of the front wheelset 1.1. to zone 3.2. in block 11, a relay 20 is energized, providing elements 19 for the conversion of the inverse code signal "KZh" into standard code signals "KZh". Thus, the yellow-red signal remains on at the traffic light 14, because in this case, in the decoder 12, the signal relay "ql" will be energized.

Optical announcer 4.6 is turned on. increased alertness and an additional audible alarm annunciator (see contacts 20.7. and 22.2. relays 20 and 22, respectively). The contacts open 22.3. and 22.1., creating the conditions for exposure through the electro-pneumatic valve 30 to the braking means 31 of the train and locomotive after stopping the inverse code signal “KZh” in zone 3.3.

The system works similarly in other zones of train (train) convergence with closed output, route and shunting traffic lights.

At the distillation signal points, an inverse code signal is not used, therefore, when the train approaches the closed distillation directional traffic lights, relay 22 is activated and, after stopping the reception of the standard code, “KZh” will self-block (see front contact 22.3.), Providing power for relay 22, and therefore creates the opportunity to follow the closed traffic light due to the preservation of the front contact 22.1. in the connection circuit of the contact 0-20 of the speed meter with the decoder 12.

The economic efficiency of the system is expressed by the exclusion of collisions of rolling stock at stations performing train and shunting work.
