Description

The invention relates to the field of railway automation and telemechanics and allows you to transfer to locomotives equipped with equipment SAUT-CM/485, information with extended value from track devices ALSN and SAUT, which allows you to increase the throughput of stations when organizing non-stop train traffic on the main tracks without deviations in arrows. The proposed method is relevant for organizing the movement of trains using the technology of interval control, including with a "virtual coupling".

Currently, the SAUT security system (patent for invention of the Russian Federation No. 2283786), used on the railway network of the Russian Federation, uses data received from SAUT track devices and ALSN automatic locomotive signaling devices to calculate the allowable speed.

SAUT track devices are a point channel for transmitting information, providing at the time of passage its binding to the location and the route set at the station with an allowable speed along it.

On most sections of the railways of the Russian Federation, automatic locomotive signaling of the numerical code ALSN is used, which provides for the transmission of one of three combinations of the number-pulse code to the track circuit: green (code З), yellow (code Zh) and red-yellow (code КЖ) and their decoding on board the locomotive by ALS receiving devices and SAUT locomotive devices. At the same time, one of the combinations corresponding to the yellow indication of the locomotive traffic light (code G) can be present both when following the traffic light with the indication “one yellow light”, indicating further movement along the main track at a set speed, and to the traffic light with another signal an indication requiring the passage of such a traffic light at a reduced speed and further movement, as a rule, onto a side track. The same traffic lights located on the main tracks of the stations can give different signal indications, and therefore, the yellow light code that appeared on the route along the main track of the station after the locomotive had passed the SAUT track device does not allow unequivocally identifying the permissible speed in end of the route. In such cases, the SAUT operation algorithm for safety conditions provides for an automatic speed reduction to the traffic light to the minimum allowable, which may not correspond to the actually established route and increase the station transit time.

Most often, this situation manifests itself when trains move in the “virtual coupling” mode, when the interval between trains is minimal, and the indication of the ALS locomotive traffic light changes from “KZh” to “Zh” when moving along the station tracks. To remove such a restriction, it is required to transmit to the locomotive an additional sign about the established route of further movement at the moment the yellow light code “Zh” appears in the track circuit.

SAUT input or waypoints set their own receiving route for each receiving-departure path.

When the train moves along the main track of the station, following the input traffic light with one yellow indication and then opening the route/exit traffic light for movement with the appearance of a yellow light at the locomotive traffic light, with the existing SAUT operation algorithm, an ambiguity arises: the next traffic light can be opened both for traffic without deviation along arrows, and with a deviation along the arrows.

The method of transmitting to the locomotive information about following the route along the main track with or without deviation along the arrows allows you to increase the speed of the safe passage of the train at the station according to the yellow indication of the locomotive traffic light by changing the operation algorithm of the "Speed limit cancellation" button (hereinafter referred to as the "OS" button) and organizing the transfer to the locomotive of an additional sign about the further movement of the train in the forward direction.

The technical solution for expanding the significance of information transmitted from the track to locomotives equipped with SAUT-CM / 485 is based on the application of a certain rule for coding routes along the main tracks with ALSN signals, the use of a new algorithm for processing ALSN signal readings, taking into account the type of code track transmitter that allows you to determine on the locomotive, the route of further movement, together with the confirming actions of the driver (pressing the “OS” button on the driver’s console SAUT, the locomotive unified built-in display unit BIL-UT, the locomotive vertical display unit BIL-V of the equipment of the complex of locomotive safety devices KLUB-U) when driving along the main track of the station with a yellow indication of the locomotive traffic light and further movement without deviating along the arrows.

Coding of track circuits is carried out using code transmitters that generate code sequences. In operated ALSN devices, transmitters KPT-515 and KPT-715 are used, which differ in the duration of the code cycle. The alternation of types of CPT at the border of block sections on auto-blocking is used in the SAUT system as a sign of the transition from one block section to another when moving along the span (as well as to control the state of insulating joints in coded auto-blocking).

Coding schemes for station tracks are mostly made in accordance with standard design materials 410811-TMP "Coding schemes for station tracks of electrical interlocking ETs-11-87". Most often, station track circuits are coded KPT-515 due to the short code cycle in combination with short track circuits at the station, especially in the throats.

It is proposed to use the existing versions of the signals received by the locomotive to organize an additional feature that determines the presence / absence of the requirement to reduce the speed behind the traffic light located on the main track (if there is a yellow light code in the track circuit) by providing coding of the reception / transmission route to the specified traffic light from code transmitters . It is proposed to assign a predetermined type of CPT as such an additional feature during the further movement of the train. To this end, the yellow light code for further movement along the main track without deviating along the arrows should be set to KPT-515, and for further movement with a deviation along the arrows - KPT-715.

The choice of the permissible speed of movement, depending on the further direction of the train, is carried out using:

- the operation algorithm of the SAUT-CM/485 locomotive equipment, taking into account the presence of an appropriate organization of coding in a particular location and the connection between the type of KPT when coding with a yellow light with an established route transmitted by SAUT track devices;

- the driver presses the “OS” button on the SOUT driver’s console (BIL-UT, BIL-V and KLUB-U equipment) with a yellow indication of the locomotive traffic light, the route does not deviate (the indication “one yellow” at the route / exit traffic light) when driving along the main station paths.

For the unconditional fulfillment of security requirements, the proposed method contains the principle of "two keys", which consists in the obligatory fulfillment of two independent conditions:

- the first condition is to change the algorithm of the "OS" button of the SAUT equipment and the procedure for using this button by the driver when the train follows the main track of the station with a yellow indication of the locomotive traffic light. According to the current algorithm, the “OS” button is blocked and does not allow canceling the speed limits set by the SAUT devices for following the side track. A change in the algorithm is proposed in unlocking the "OS" button when the train follows the main track of the station with a yellow indication of the locomotive traffic light. This condition is necessary, but not sufficient, because in the event that the driver mistakenly presses the “OS” button when following the traffic light with a deviation to the side track and switching the locomotive traffic light from “KZh” to “Zh”, it may lead to the cancellation of the speed limit when the train continues to move to the side track;

- in order to exclude erroneous actions of the driver by pressing the "OS" button, the proposed method implements the second mandatory condition, which consists in transferring to the SAUT-CM/485 locomotive devices from the ALSN track devices a sign of further movement along the station with a deviation along the arrows, or without deviation. Currently, such a sign is transmitted to the locomotive only if the station has ALS-EN track devices, and the locomotive is equipped with safety devices of the safe locomotive combined complex BLOCK or KLUB-U.

The method of transmitting to the locomotive information about the route along the main track with or without deviation along the arrows expands the scope of automatic determination of the direction of further train movement at the station for all locomotives equipped with SAUT-CM/485. An additional feature for unlocking the "OS" button by the technical means of the locomotive equipment is to check the coding of the rail circuit of the station receiving-departure track with the KPT-515 code transmitter when following the arrows without deviating.

The hardware implementation of the proposed method involves the use of resources available in operation, in particular, code track transmitters.

The circuits for switching on transmitter relays are being finalized. For an even-direction input traffic light (hereinafter referred to as “H”), contacts of the main route relay of the route traffic light CHMNA “CHMNAGM” are added to switch the CPT.

To implement the proposed method, the software of the SAUT-CM/485 locomotive equipment is adjusted to build the program speed of the locomotive depending on the location of the train, the received code information from the SAUT track devices and the corresponding organization of the coding of track circuits. It is also mandatory to programmatically control the pressing of the “OS” button when the locomotive traffic light shows yellow, the route without deviation (“one yellow” indication at the route / exit traffic light) when moving along the main track of the station. At the same time, the coding of the track circuit is checked by the KPT-515 code transmitter to build a program speed for movement without deviating along the arrows after the next traffic light. This requirement is introduced to protect against unregulated replacement of the types of CPT (a human factor is possible) and to prevent the movement of a train with a deviation along the arrows at an unacceptable speed. An example of switching the CPT for different options for the further movement of the train is shown in figure 1.

The ALSN signal (continuous automatic locomotive signaling), which is perceived by the locomotive, is transmitted along the track circuits using CPTSh (plug-in code track transmitters). KPTSH are mainly 515 and 715, which differ in time parameters.

PMK and PPK - supply "minus" and supply "plus" 24 V;

R - resistor;

CHGT - the main transmitter relay. The contacts of this relay are included in the coding circuit of the track circuits with the signals ALSN of the receiving route at the input traffic light Ch;

CHMPAPKV, NAPCV, CHKV - contacts of code-switching relays of route sections;

CHMNAS - contacts of the signal relay of the route traffic light CHMNA, is triggered when the traffic light CHMNA is opened;

CHMNALS - contacts of the linear signal relay of the route traffic light;

CHMNA, CHMNAGM - contacts of the main route relay of the route traffic light CHMNA. According to the state of the CHMNALS and CHMNAGM relays, the variant of the train route is determined;

The listed relay contacts choose which code - 3 (green), Zh (yellow) or KZh (red-yellow) will encode the route of receiving the train.

Relay CHMNAGM is responsible for following straight or by deviation. Thus, the indications of the traffic light "yellow" or "two yellow" are differentiated and the following of the train is determined with a deviation along the arrows or without a deviation. In case of deflection along the arrows, the transmitter relay switching circuit uses the transmitter type 715, in contrast to the case of movement without deflection, where the CPTS 515 is used.

Thus, if there is an additional sign, using a certain type of CPT, it becomes possible to increase the speed of the station along the main tracks without deviations along the arrows during further following and fulfilling the safety requirements according to the SAUT operation algorithms.

The proposed method of transmitting to the locomotive information about following the route along the main track with or without deviation along the arrows is based on the resources available in operation and can be implemented without significant hardware costs.
