Description

This invention relates to dispatching train control devices for railway sections equipped with an automatic blocking system.

Devices for dispatching control of train movement are known, in which boards are used, switchgears at the control room and a relay chain with linear cells at each controlled object, and the alternate connection of the control room with control line objects (block sections) is carried out via two line wires.

The proposed device improves the reliability of monitoring the state of linear objects and reduces the period of checking them at the control room.

This is achieved by the fact that at the distribution station one generator is connected to the generator of sending negative clock pulses to the line and delaying chains in terms of the number of controlled objects, to another wire there are selective triggering devices, and at linear points to these two wires are connected from the delay, their chains with amplifier-corrector and weighing generators.

The drawing shows a skeleton diagram of the proposed device for dispatch control, consisting of station and line devices.

The station device includes a clock generator; delaying chains in accordance with the number of controlled objects 2, 3 4; selective device 5 and trigger relays 6, 7. and 8.

Linear devices include linear cells 9, 10 and //, each of which consists of a delayed chain with a corrector 12 and a generator from a hook and 13.

The clock generator sends a negative pulse to the line, and at the same time the same pulse is sent to the delay line at the control station. When the next controlled object reaches the first controlled linear object, the pulse undergoes a time delay. The pulse is displaced by the time it takes the artificial circuit and the line between the objects to pass, and again undergoes a time delay.

A pulse passing through the line serves to alternately turn on the generators installed at the controlled objects.

In this case, each linear generator with extraneous excitation during the passage of a pulse is converted into a generator with self-excitation.

As a result, vibrations with the appropriate frequency will be sent to the distribution station.

These oscillations at the station are amplified and transmitted to the selective device. Time-separated pulses from an artificial delay circuit are supplied to the same device.

When the pulses from the line coincide with the pulses from the delay line of the control panel, the corresponding triggering relay connected to the emitter circuit triggers, which leads to a change in the power supply circuit of the light bulb on the display board.
