The system of protection of level crossings works as follows.

Traffic safety is ensured by:

- fencing of the crossing zone 4 of the EHZ 3.1, 3.2, 3.3 and 3.4 after switching on the traffic light;

- ensuring automatic control of the freedom of the crossing zone 4 from vehicles, foreign objects that pose a threat to the safety of the train approaching the move;

- ensuring the vehicle leaves the crossing zone 4 after turning on the traffic light, as well as after raising the EEC 3.1, 3.2, 3.3, 3.4 at the crossing 4 on the approach of the train;

- the use of automatic voice notification of traffic participants at the crossing 4 about the approach of the train to the complete liberation of the crossing zone 4.

- the use of automatic voice notification of traffic participants at crossing 4 about a dangerous situation;

- providing video surveillance of the transport situation at level 4 from the post UP 26 at the nearest station;

providing remote control of the technical means of moving 4 from the post UP 26, as well as ensuring the control of the technical condition of the technical means;

- the use of automatic video recording of events at relocation 4 with archiving and storage of recorded data;

To ensure the specified traffic safety:

- EUS 3.1, 3.2, 3.3 and 3.4 are installed in the roadbed;

- the rise of the EEC 3.1, 3.2, 3.3 and 3.4 is performed with a delay after the traffic light is turned on, the delay interval exposure is determined by the formula:

t _memory = Kv (L _per + LTC) / VTC, s,

where Kv = 3.6 is the conversion factor for speed units from km / h to m / s;

L _per - the distance between the traffic lights, m;

LTC - maximum vehicle length - 24 m;

VTC - the minimum permitted vehicle speed at the crossing is 8 km / h.

In this example

_tsu = 3.6 (18 + 24) / 8 = 18.9 s.

If the crossing zone 4 remains occupied after the expiration of the delay interval, the rise of the EHZ 3.1, 3.2, 3.3 and 3.4 is automatically blocked.

After the train clears the track of the crossing zone 4, the EHMs 3.1, 3.2, 3.3 and 3.4 are automatically transferred to the lower position.

The presence of a vehicle in the 1-1n railway zone is controlled by DPI 8.1, 8.2, 8.3, 8.4 - 8.1.n, 8.2.n, 8.3.n, 8.4.n, BDPI 29 and VD24.

The presence of vehicles is monitored by DPI 8.1, 8.2, 8.3, 8.4 - 8.1.n, 8.2.n, 8.3.n, 8.4.n, receiving signals from VK 6.1 and VK 6.2 installed at the crossing 4. Voice notification is carried out by WP 5, established on the lighting poles 4.

Vehicles located in relocation zone 4 are displayed on VDO 23.

At the same time, traffic lights 8.1, 8.2, 8.3, 8.4 - 8.1.n, 8.2.n, 8.3.n, 8.4.n and VD 24 record the presence of vehicles on the railway 1–1n of crossing 4 from the side of the traffic light 2 A and from the side of the traffic light 7B .

The order of work when following the train

In the process, the devices of the railway crossing protection system KUP 21 at level 4 performs the following functions:

- continuously monitors the state of free / busy sections of the approach and track of any of the railway 1-1n level 4 by counting axes PS;

- continuously monitors the current position of all HPS 3 at level 4;

- receives and processes data from the DPI 29 and the control unit;

- transmit the relevant data to the post TO 26 in the BVI 20.

BPV 13 transmits video signals from VK 6.1 and VK 6.2 to the post DO 26 in BPV 25.

At the post UP TO 26, BVI 20 continuously controls the operation of UOID 19, which displays in real time the current status of devices at level 4.

VD 24 processes the signals received from VK 6.1 and VK 6.2, determines the fact of movement in the crossing zone 4 and transmits the corresponding data to VDO 23 and to BVI 20. WP 5.1 and WP 5.2 are ready to play sound phonograms.

The vehicles located in the crossing zone 4 are displayed on the VDO 23. At the same time, the PDI 29 (through the use of the PDI 8), the control panel of the microwave oven 31 (by means of the microwave oven 30) and the VD 24 record the presence of the vehicle on the 1-1n railways and separately on each of the railways adjacent to the railways 1-1n sections of the road from the traffic light A2 and from the traffic light B7.

If the PDI 29 and the control unit of the microwave oven 31 fixes the fact of the presence of a stationary vehicle, and the VD 24 at the same time detects the absence of movement in the railway zone 1-1n, then UOID 19 automatically generates periodically short sound signals in order to attract the attention of the duty operator.

When the train moves along any of the railway lines 1-1n towards the railway crossing 4 at the time of the head of the train for the first 9.1 or fourth 9.4 PSO KUP 21 records the occupation by the train of the corresponding section of the approach to moving 4 and generates control commands to enable the crossing signaling. The indicated commands are perceived by the control center by traffic lights and acoustic detectors 15 and RI 12. The control center 15 includes red lights of crossing traffic lights A2 and B7 in flashing operation mode. RI 12 through the use of WG 5.1 and WG 5.2 generates control commands to enable voice notification of traffic participants at level 4 about the approach of the train.

Simultaneously with fixing the occupation by the train of the corresponding section of the approach to moving 4, the PMC 21 starts the countdown of the time interval t _Зy . After the time t _{zy expires, the} PMC 21 sequentially with an interval of 0.2 s generates commands for lifting the first and fourth HMS 3.1, 3.4, and then, after 4-5 s, sequentially with an interval of 0.2 s forms commands for lifting the second and third HMS 3.2, 3.3. These commands are perceived by MCC 11 EZU 3.1, 3.2, 3.3 and 3.4. MCC 11 translate the corresponding ESA in the upper position.

After the train releases the track section of crossing 4, the PMC 21 sequentially, at intervals of 0.2 s, generates commands for lowering the memory device 3.1, 3.2, 3.3, 3.4. After the translation of all the EHMs to the lower position is completed, the red lights of the crossing traffic lights A2 and B7 and the audible alarm turn off.

The operator on duty has the ability to switch the devices of the railway crossing protection system into local control mode. In this case, the control from the remote control to 26 is blocked. In the local control mode, the operator on duty, being at the ShchMU 22, has the ability to force the EHZ to lower position or hold it in the lower position by pressing and holding the corresponding buttons on the front panel of the ShchMU 22.

If any of the EEZ prevents the vehicle from leaving the crossing zone 4, and also in the event of a malfunction, the operator on duty has the opportunity to turn off the devices of the railway crossing protection system (switching to Normalization mode) by pressing the corresponding button on the PDO 18 or SCHMU 22. after pressing the corresponding button, the PH 16 is turned on. The PH 16 contacts form the control signals to translate all the EECs to the lower position. After receiving the MSD 14 control of the lower position of all EPCs, the devices of the railway crossing protection system are turned off. At the same time, automatic crossing signaling devices continue to operate in the established order under the control of PMC 21.

In addition, the operator on duty has the ability to manually translate any of the EHLs to the lower position using a special hook handle.

Operating procedure when the traffic light is on and there are 4 moving vehicles in the crossing zone.

If after the lapse of the time interval t _z after turning on the traffic light, in the railway zone 1-1n ДПИ 29 and the control panel of the microwave oven 31 the vehicle is fixed in the crossing zone 4, then the control unit 21 delays the formation of control signals to raise the ECU 3.2 and UZ 3.3 until the zone 4 of the railway . The delay in lifting these EHZs allows the vehicle to leave the relocation zone 4.

If the PDI 29 fixes the vehicle over any of the ECM 3.1, ECM 3.2 or ECM 3.3, ECM 3.4, then PMC 21 delays the formation of control teams to raise ECM 3.1, ECM 3.2 or ECM 3.3, ECM 3.4, respectively, until the vehicle of the corresponding ECM is released. This delay is necessary to exclude the possibility of damage to the undercarriage of the vehicle moving above the ECM 3.1, ECM 3.2 or ECM 3.3, ECM 3.4, respectively.

Operating procedure when the traffic light is on and there are 4 stationary vehicles in the crossing zone.

If, when the traffic light is switched on, DLI 29 and the control panel of the microwave oven 31 record the presence of a stationary vehicle, and the VD 24 detects the absence of movement in the 1–1n railway zone, then the "Alarm!" Mode will automatically turn on. The operator on duty has the ability to turn off the "Alarm!" (for example, in the case of a false positive operation of the microwave oven 30) by pressing and then depressing the same button on the PDO 18 or on the ShchMU 22.

In the "Alarm!" RT 17 is turned off. RT 17 contacts turn on the voice notification of traffic participants about a dangerous situation at level 4 and a control command is formed to transfer the ECU to the lower position. At the post TO 26, the contacts of RT 17 are switched in the external control circuits of BTS 28. The BTS 28 block, using the transmitting BPS 27, transmits a cyclically corresponding voice message to the locomotive approaching the move 4, and the locomotive team takes the necessary actions depending on the situation at the move 4. In addition, at the post UP 26, the corresponding indication is displayed on the screen of the UOID 19 and the voice notification is turned on.

Depending on the current situation at level 4, the operator on duty can turn on the "Alarm!" Mode at any time. forcibly by pressing the button of the same name on PDO 18 or on the ShchMU 22.
