The device contains (Also a warning signal unit 15, the outputs of the directional detecting unit 12 are connected to the inputs of the route hostile unit 16, one output of which is connected to the input of the blocking signal generating unit 17. The device also contains the blinking mode unit 18, the traffic lights unit 19 of traffic lights , block 20 time delays, block 21 bans, fire block 22 railway traffic lights signal unit 23 road traffic lights, i signal unit 2k railway traffic lights, block 25 automatic detection of damage, whose output is connected with the lamp unit 26 lesions ...

The automatic crossing signaling device operates as follows.

Road facilities for special and emergency purposes are equipped with priority information transmission devices that are activated simultaneously with the light and sound signaling. Normally, when there are no trains in the approximation areas at train lights 10 and 11, prohibitory indications are turned on, and motorway lights 8 and 9 are turned off.

Jari of an unfavorable production situation and entry into a reasonable odd area approx.;; 1x, the signal from sensor 1 is fed to the input of block 12. In block 12, this signal is remembered, the direction of movement of the train is determined even in the open state of the track circuit monitored 2 and 3, a signal is generated that arrives at the first input of the hostility block of the routes 16. In block 16, the absence of hostile movements to the route through the crossing is checked and, if such are absent,

That signal generated by the directional direction determining unit 12 is fed through the hostility block of the routes 16 to the input of the time delay unit 20. From the influence of this signal in block 20 a control signal of a certain duration is produced and is fed to the input of the inhibitor block 21. The following situations are possible. A sensor 6 with or near the priority information transmission device is located above or near sensor 6 or 7. This information in the form of an electrical signal from sensor 6 or 7 is fed to the input of block 13. In block 13, information is stored and a lime signal appears at its output, which is fed to the input of block. 21. In block 21, this prevents the control signal from passing on its output, as a result of which the block 17 of forming the blocking signals blocks the switching on at the train lights 1 1 allowing indication and on it there is a prohibiting signal. At the same time, from the output of block 13 to the fourth input of the signal block 23 of road traffic lights, there is also a limestone signal, which excludes the presence of road traffic lights and warning alarms. Thus, the crossing signaling will remain in the normal position for the duration of the special motor vehicle following the crossing, which is monitored by the sensor 5 for the presence of obstacles. In this case, the primary information is reset in the block for determining the priority of motion 13 and the formation of the extraction signal stops.

As a result, the blockage from operation of blocks 23 and 21 is removed and the signaling block of traffic lights 23 includes warning signs and red lights 27, 28, 29 and 30 of traffic lights 8 and 9. After turning on the traffic lights, that: it is checked by block 19 fires the relay by checking the integrity of the lamp filaments, from the output of the block 19 of fire relays of road lights to the input of the block forming the blocking signal 17 is given a command to control the freeness of the crossing zone, which is carried out by the block of automatic detection obstacles T4 using the sensor 5 obstacles. If there is no obstacle, the 1 signal generated by the automatic detection unit of obstacles enters the input of the block forming signals If there are signals at the inputs of block 17 (respectively) indicating that the train is in the approximation area, the traffic lights are closed and the crossing zone is free its output a signal appears, which is fed to the input of the signal unit of train traffic lights 24; which switches, the traffic light of the prohibiton-indication to the permitting signal. Thus, The device implements the principle of mutual exclusion of ne: crossing traffic lights, since the opening of the train traffic light 11 becomes possible only after monitoring the prohibiting state of traffic lights 8 and 9. In normal state, the transfer to the alarm goes after the release of zones controlled by sensors 1, 2 and 3 (. Above the sensor 6 or 7 near them there is a special motor vehicle - i No means with the device turned on | 5Transmission of priority information. , In this case, the blocking of the signaling blocks of the road 23 and the railway, 10 06 light traffic lights will not occur and the signaling will switch on without blocking. If the railway unit after taking an odd area of approximation, monitored by sensor 1, BCTynaet in the zone controlled by sensor 2, and there is a special vehicle above sensors 6 or 7 with the priority information transmission device turned on, the traffic lights 23 are not blocked and the information from the hostile block of the routes 16 is directly fed to the input of the block of forming the blocking signals 17, which also prevents blocking; and block 23- in view of turn off the alarm of level crossing occurs and this vehicle will proceed through the crossing after the complete release of its area of railway rolling stock. The use of the proposed device compared to the known one provides for the movement of special vehicles through the crossing with a minimum of 9 (with delays provided that the traffic safety requirements are met and shortens the time of elimination of emergency production situations.
