(54) DEVICE FOR MOTION CONTROL

.- -: /, ...:

This invention relates to railway automation devices that provide interval control and. traffic safety on metrypolitenakh.

A device for controlling the movement of a train is known, comprising a relay for controlling an electropneumatic valve and a control braking efficiency control unit connected to a power source through the train station relay connected in series; the front contact of the speed control relay and the front contact of the power control relay on an electropneumatic valve which is connected in parallel with the electropneumatic valve through the front contact of the control relay of the electropneumatic valve, Pneumatic dotormazhivaTni valves connected through the front contact of the dotormazhivna relay, as well as the running mode relay, the overrun relay, the brake control relay, the train station relay, the actual speed control relay, and 1;) the main relay 1.

/ The disadvantage of the known device is not enough reliable TRAIN

the deceleration of the train while stopping it on the climbs when it is unraveled. signaling indications and disturbances in the circuits of the electro-pneumatic dotorzhazhivaniya valves, leading to the intermittent process of the introduction and release of the emergency brake. .

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that the relay controlling the electropneumatic valve is connected to the power supply. neither via the front contact of the overrun relay connected in parallel with the relay connected to the brake control relay, the rear contact of the running mode relay, the front contact, the stationary relay, and the rear contact of the actual speed control of the train and the rear contact of the on relay.

In the drawing, the elec- trical principle is represented (the schematic of the device).

The device contains a relay 1 control electropneumatic valve with front-contact 1.1, connected to a power source through

thirty . serially connected front contacts 2 and 3, speed control relays. Power control relay 4 on an electropneumatic valve with front contact 4.1, front contact 5, train station relay and; 6jioK b control performance braking. The electro-pneumatic valve control relay 1 is connected to the power supply circuit through series-connected rear contact 7 of the relay, front contact 8 of the train station relay, rear contact 9 of the actual train speed relay, rear contact 10 of the traveling mode relay and front contact 11 of the overrun relay, parallel to which enabled front contact. 12 brake control relays. The electro-pneumatic valve 13 and the power control relay 4 on the electro-pneumatic valve are connected to the power source through the front contact 1.1 of the relay 1 control of the electro-pneumatic valve, and through the front contact 14 of the dotormazhivna relay the dotormazhivany valves are switched on. .

The device works as follows.

When the train is on the rise, when the permissive signal is indicated and the valve power supply circuit is in good condition, the electropneumatic valve control relay 1 is energized through the service braking control unit b connected in series, front contact 5 of the train station relay, front contact 4.1 of the power control relay 4 on the electro-pneumatic valve and front contacts 3 and 2 speed control relays. The electro-pneumatic valve 13 and the power control relay 4 on the electro-pneumatic valve are supplied via the front contact 1.1 of the electro-pneumatic valve control relay 1. The electro-pneumatic dotormage valves are powered through the front contact 14 of the dotormazhivany relay.

In case of disturbances in the power supply circuit of the dotormaging valves, the service braking efficiency control unit 6 breaks the power supply circuit of the electropneumatic valve control relay 1. This leads to a loss of power supply of the electropneumatic valve 13 and power control relay 4 to the electropneumatic; tic valve. The train is braked with an emergency brake and the service braking efficiency control unit B prepares the power supply circuit of the relay 1 for controlling the electropneumatic valve. However, this power supply relay 1 does not receive, since the functional contact 4.1 of the power supply control valve of the electro-pneumatic valve is open. 4.1.

To remove the train's extra brake, after eliminating a malfunction in the power supply circuit of the dotormazhivany valves, it is necessary to remove the power supply for a short time and re-apply it. In this case, the relay 1 is controlled by an electropneumatic valve for a short time through the front-connected contact 11 of the over-run relay connected in parallel, which is connected in parallel with the front contact 12 of the brake control relay,) POWER contact 10 of the running mode relay, rear contacts 9 of the actual speed control relay, front contact 8 relays of the station of the train and the rear contact 7 of the turning on relay after the end of the holding time for the actuation of the turning on relay. This power circuit is interrupted by a spindle contact 7. If the power supply circuit of the dotormazhivany valves is in good condition and they are effectively braked, the electropneumatic valve control relay 1 will receive power through the main circuit.

Thus, the proposed device eliminates the possibility of a train rolling down when it stops on an ascent with an enabling signal indication and the occurrence of faults in the power supply circuit of the dotormazhivan valves, which increases the reliability of braking and safety

train movements.
