SU41394A1 - Device for signaling the intensity of traffic on electric, especially urban railways - Google Patents

Description

Signal devices are used to record the intensity of traffic on railways, mostly urban, in which usually an auxiliary wire is used, which is pulled by moving carts as a current collector and connected to a relay controlling the operation of signal devices.

The indicated relay, according to the invention, serves to close two parallel branches, one of which includes signaling devices indicating weak traffic, and the other signaling devices that operate only when the frequency of the auxiliary wire is higher than the set frequency.

The transmission of signals from monitored points can be carried out either by separate wires for each point, or by common (two or three) wires from all controlled points to the central point; in the latter case, the control parcels of the currents are coded and one or another system for the selective reception of signals is installed at the central point for reception.

In FIG. 1 shows a schematic of the proposed device;

FIG. 2-zid on top of its recording part; FIG. 3-circuit selective signaling.

The drum 7, which is driven in a uniform motion by the clock mechanism 2, draws the paper tape from the roll to the drum 5; above the tape is a recording pen 4 in the form of a curved capillary tube, the right end of which is immersed in ink poured into the ink tank 5; The capillary tube 4 is mounted on the cortex of the electromagnet b, and therefore, with periodic excitations of the latter, rectangular zigzags will be obtained on paper. The current in the winding of the relay 6 is included by the current collector 7 of the car or electric locomotive when the latter passes under the auxiliary wire 8. The direct current passes in series through the resistance 9, recording and signaling relay JO to the ground. The inclusion of a current in the winding of the relay b leads to obtaining a record on a paper tape, and the passage of current through the JO relay causes the attraction of its core //. With the release of the crust of the relay 10, the local battery / 2 circuit closes through the winding of the thermal (or otherwise operating with a time delay) relay / 5, the latter causes contact closure} 4, through which the control lamp / 5 turns on, signaling a suspension or too weak (below norms) movement in a controlled area.

When the relay trips W, its measles are transferred to the upper contact and closes the circuit through the winding / 5 of a thermal or other relay with a time delay. The time delay of the relay 16 is adjusted so that when the individual circuits of the wire 8, following each other with a frequency not exceeding the normal, it does not have time to close the contacts / 7; if the wire 8 starts to close very often at increased intensity of motion, then relay J6 will have time to close the contacts 17, through which the lamp 18 will turn on, signaling a part of the movement exceeding the normal one.

In the case of receiving control instructions from several points on common wires using selection, the wire from resistance 9 enters code cell 19, after which it is transmitted as cell current to cell 20, where it is decoded and goes to the relay corresponding to the point from which control.

Recording instruments from all monitored items are assembled in the form of an apparatus, where each item has a recording pen and two control lamps.

If desired, a test bell can also be attached to the lamps.

Upon receiving a picture of the distribution of the frequency of movement over a controlled network, the distribution agent of the central center can take measures to regulate the impaired uniformity.

movement and to prevent disruptions of the latter.
