Abstract

Usage: prompt detection of a faulty section of the dispatch communication line. The invention: connect another radio station, which is known to be working, transmit through it over the air a selective connection signal to the selected radio station and, using the received signal, connect it to the console of the distribution station.

The goal is achieved through the organization of another (over the air) signal transmission path for a selective connection to the selected stationary radio station. 2 Il.

Description

Vffif

The invention relates to a transport communication technique and can be used for the operational control and restoration of radio communication of a train dispatcher.

The purpose of the invention is to provide prompt detection of a fault.

Figure 1 shows a structural electrical circuit diagram of a device implementing the proposed method; Fig. 2 illustrates stress plots showing its operation. ten

The device contains a remote control station 1 of the distribution station, a selected and adjacent stationary radio stations 2.1, 2.2, which include a selective amplifier-driver 3, a switch 4, 15 a transceiver unit 5, a linear unit 6, a selective connection unit 7, the controlled and reserve sections 8, 9 of the dispatching line and the locomotive radio station 10.20

The technical essence of the proposed method is as follows. Another radio station is connected, the selective connection signal of the selected radio station is transmitted through it, 25 the selective selective signal received over the air is selectively selected, the selective signal received over the air is selectively extracted, it is used to switch the selected radio station the radio station to the backup section of the wired connection and turn on its selective connection unit, and by the presence or absence of the control signal of its connection to the console 35, conclude that there is no fault the strengths of the line segment of the wireline communication or reception-transfer, respectively.

In the absence of malfunctions, the train dispatch channel operates in accordance with its quivering purpose and the train dispatcher can conduct official conversations with locomotive drivers located in different sections from control station 1 through the control section 8 and selectable and adjacent stationary radio stations 2.1 2.2. Communication on the dispatcher's call by locomotive machinists is also carried out in accordance with the standard designation of the locomotive (for example, 42RTM-A2-FM) and stationary (43РТС-A2-FM) radio station.

The most frequent damages in the train dispatch channel are damages to the wired line sections (open circuit, short circuit, insulation fault, high level of interference) and stationary radio failures. Such damages and failures that adversely affect the safety of movement require their prompt detection and elimination, the realization of which is complicated due to the on-site nature of the repair work.

The determination of the cause and location of the defect is carried out as follows.

Suppose that at the moment when a dual frequency signal of a selective connection of a selectable stationary radio 2.1 is transmitted from the console 1, the dispatcher did not receive a control signal to connect it to the monitored section 8, that if the communication channel with the neighboring radio stations 2.2 works, it will indicate that one of the two listed faults. Along with the problem of localizing the malfunction and its elimination, the problem of promptly restoring communication arises, for which the dispatcher (without calling and sending the assembler to the line) has to switch the selected radio station 2.1 to the reserve section 9. And since in case of a malfunction of the controlled section 8 this cannot be done, This remains the only way to make such a switch using the signal of a selective compound transmitted over the air and formed after receiving the radio before its analogous to Ida transmitted to the stationary radio station 2.1 over the monitored section 8. At the same time, the received over the air signal after bringing it to the required form should be fed to the input of unit 7.

In this situation, the dispatcher transmits to the controlled section 8 a signal of the selective connection of the neighboring stationary radio station 2.2, which is known to be in good condition (the Ufira signal). After receiving the control signal Uk2 for connecting a selectable stationary radio station 2.1, the dispatcher from the console 1 must transmit the turn-on signals of the neighboring stationary radio station 2.2 to the transmission and selective connection of Uf3f4 to the selected stationary radio station 2.1. Note that the call by the signal of the neighboring stationary radio station 2.2, its activation for transmission and the broadcast of the selective connection signal of the selected stationary radio station 2.1 can be accomplished by transmitting from the control panel 1 of one transmitting parcel consisting of the code signals of the selective connection of these radio stations (tn) occupying time interval from t2 to ts. In the case of a selectable stationary radio 2.1 operative, the latter, via block 5, will receive and extract the selective coupling signal Ufara by the selective amplifier 3 which is used simultaneously in the control of switch 4 to switch the selected station 2.1 to reserve section 9 (Up) and feed it to block 7. After receiving the control signal of the connection of the CCD of the radio station to the backup section 9, the dispatcher can again establish a radio wire connection to the locomotive radio station 10. In case of non-receipt of a Qc signal, the dispatcher may conclude

on failure of a selectable stationary radio station 2.1.
