SU42444A1 - Device for code dispatch signaling - Google Patents

Description

The present invention relates to code dispatch signaling for use mainly in mine and in-plant rail transport using a track circuit for signaling.

The essence of the invention is the use of a relay pulse decoder.

Along the whole railway track, at local distances, the secondary windings of the transformers 7 are included in the rails, the primary windings of which are included in line 2, which also includes a rotary key mounted on the dispatch control panel.

Automatically transmitted at the appropriate position of the key 3 code (composed of dots and dashes) consists of two ciphers: one ringing, received by all steam locomotives or electric locomotives, and the other, being an order and received after the call code only the locomotive or locomotive, to which the order refers . Other orders that are not related to it cannot be accepted due to the effect of the call code on a special relay. Line 2 can also be used for reverse telephone communication between the driver and the dispatcher. The indicated codes are spread by transformers throughout the railway track and steam is accepted (323-324)

Carts or electric locomotives, each of which has a device, consisting of the receiver 4 itself, the filter 5, the amplifier 6, the decoder, and the indicator. The decoder consists mainly of two groups of relays - one group of fast-acting relays 7, 8, 9 and another group of slow-acting relays 10, 11, 12. The high-speed relay 9 is triggered when the third point of this signal is transmitted; slow relay 12 is activated when transmitting the first dash contained in this signal, etc.

Relative to the relay contacts are denoted by the corresponding numbers. All relays are brought to the normal position by the bouncing relay 13. If the time delay of each relay 7, 8, 9 is indicated by t, then the time delay of relay 10, 11, 12 will be 3, and relay 13 will be at least 41.

The current transmitted frequency from a linear circuit or amplifier falls into the first relay of each group. Each triggered relay is blocked by switching the line to the next relay in its group. Each triggered relay of the second group releases the last relay of the first group, since it operates simultaneously. For example, consider the transmission of two points and one dash. When sending the first point, the relay 7 is activated and its contacts go to the working position. The same thing happens with relay 5 and its contacts when sending the second point. Then, when transmitting a dash, not only relay 10 is triggered, but also relay 12, which immediately returns to its normal position, since one of the contacts of relay 10 is in relay circuit 9. When the code is sent, all relays of both groups come to normal position due to the actuation of the burglary relay 75. The connection of the decoder to the indicator (not indicated in the drawing) is carried out by one of the known methods.

The subject matter of the invention.

A code dispatch signaling device, for example, for in-plant and mine transport, using a separate line for transmitting pulses through a series of transformers into the track circuit, characterized by using a pulse decoder in the receiver consisting of several relay groups by the number of pulses of different duration, for example, points and a dash in Morse code, included so that in each relay group the points pass sequentially through separate relays, starting with the first, in the order sent are homogeneous pulses, with each triggered relay of the same group remained samozaderzhivayuscheys chain and each triggered relay of any group freed the last relay of the previous group.
