RU85231U1 - DIGITAL TRANSMISSION DEVICE FOR DIGITAL COMMUNICATION (UPDL) - Google Patents

Abstract

Area of use. The invention relates to the field of railway transport, in particular to a safety system for the movement of rolling stock. It is intended for receiving data on the state of rolling stock from distillation equipment KTSM-01D after passing through the control section, processing the information received according to the algorithm implemented in the KTSM-01D LPK personal computer program and transmitting the processing results to the locomotive. The data transmission section to the locomotive is located at a distance of 2 km from the control station KTSM-01D along the train. UPDL allows you to quickly provide the train driver with information about the serviceability of the rolling stock (the presence of axleboxes with dangerous levels of heating, exceeding the permissible size of the moving units, etc.), which will allow the locomotive team to make the right decision in time for further controlling the movement of the train as in the absence of communication with the chipboard and the train dispatcher and in the event of loss of communication of the distillation equipment with the personal computer of the linear control point (or in the event of a PC failure). UPDL transmits data on the status of the rolling stock to the on-board equipment of the automatic braking control system (SAUT) located on the locomotive, which makes it possible to automatically, without the participation of the train crew, control the train's movement modes in case of malfunctions in the rolling stock, and also allows you to document the results of the control KTSM-01D equipment of axlebox units and the size of moving units in the on-board recorder of SAUT equipment. The main parts of the UPDL are: the KI-6M information concentrator (located together with the KTSM distillation equipment installation), the interface with the USG generator, a track generator whose load is a cable (part of the rail connected to the generator output with two jumpers) and an ID-D2 sensor. USG, Generator and ID-D2 sensor are located on the data transmission section of the locomotive. Data with the results of the control of the train comes from the distillation equipment KTSM-01D in KI-6M, which transmits them to the station PC and USG. PC and USG process the received information and after leaving the train from the control section, transfer the results of the monitoring, respectively, to the monitor to control the chipboard and to the track generator for transmission to the locomotive. The generator, having received the control results from the USG, starts generating the corresponding message in the loop. When the locomotive passes through the area where the UPDL is located, the message issued in the loop is received by the receiving antenna of the on-board equipment of the SAUT. The on-board equipment of SAUT makes a recording of the message in the registrar and its output to the indication of the driver’s console, and also generates an audio message about the status of the rolling stock. ID-D2 sensor is reversible. It prohibits the transmission of data to a locomotive in the case of train movement in the “wrong” direction. The use of UPDL, due to the introduction of a backup channel for transmitting the results of train control directly to the locomotive, will improve the safety of rolling stock, and will also largely eliminate the influence of the human factor on high-speed train modes.

Description

The utility model relates to the field of railway transport and can be used in conjunction with control equipment for axlebox units KTSM-01 D on the Russian railway network.

The purpose of the utility model is to increase the safety of movement of rolling stock by creating an independent additional channel for transmitting data on the state of rolling stock directly to the locomotive in control areas.

This allows you to quickly provide the train driver with information about the serviceability of the rolling stock (the presence of axleboxes with dangerous levels of heating, exceeding the permissible size of the moving units, etc.), which makes it possible for the locomotive team to make the right decision for further control of the train’s movement . The transfer of data on malfunctions of the rolling stock to the automatic braking control system (hereinafter referred to as the Saute) makes it possible to implement an algorithm for controlling the speed of a train in the event of a malfunction recorded by KTSM-01D equipment.

The principle of operation UPDL

After the rolling stock passes through the control section equipped with KTSM-01D equipment, data on the control result from the distillation equipment KTSM-01D, block PK-02PD (2) are sent to the information concentrator (4) UPDL, from where the station-stage is transmitted via the communication channel at the automated workplace of the LPK station (3), and through the communication channel they enter the TSI. The USG, similarly to the personal computer of the workstation of the LPK station (3), processes the received data, converts it to the form necessary for reception by the Generator, and transfers it to the Generator via the communication channel. Having received the data, the Generator generates a telegram (message), which is understood by the locomotive equipment of the SAUT and begins its cyclic transmission to the loop.

Rolling stock, after passing the section where the control point is located, follows the data transmission section to the locomotive. When the locomotive passes along a segment of the path on which the loop of the UPDL equipment is located, a telegram is transmitted containing the results of the rolling stock control to the locomotive equipment of the SAUT. On board the locomotive, the control result is displayed on the driver’s console and in the form of an audio signal, and is also recorded in the SAUT data logger.

The generator, having received a message from the USG, performs its control, and, with a positive result of the control, accepts it for execution, i.e. forms a message (telegram) and sends it to the loop. If the control result is negative or there is no message from the USG for 30 seconds, the Generator transmits a telegram to the loop in which a sign of a failure of the UPDL equipment is transmitted. The format, coding method and transmission rate of telegrams transmitted to the cable correspond to the accepted protocol of exchange between the Generator and the locomotive equipment of the SAUT

The Generator’s loop is formed by an electric circuit formed by a segment of the right (in the direction of travel) rail of 10 m in length, with two standard jumpers providing rail connection with the UPDL cable network.

After transmitting telegrams to the loop and passing the first two axes of the locomotive of the ID-D2 inductive sensor, the USG stops issuing the current message transmitted to the Generator and starts issuing a test message until the next data reception from KTSM-01D. The test message is not displayed by the SAUT locomotive equipment, which is necessary if, after the train that went through the control section, the train follows the wrong path in the opposite direction. Any telegram transmitted by the Generator to the loop is cyclically repeated by it until a new message is received from the USG.

The Generator’s communication channel is a two-wire communication line with the following parameters: FSK modulation type (V23), 1200 baud information reception and transmission rate, 8N1 send format, asynchronous, half-duplex receive / transmit mode; the exchange protocol between devices is a specialized packet with a CRC32 checksum of the type of “request -” response. The length of the request packet is 12 bytes, the length of the response packet is 8 bytes. USG Exchange Cycle - Generator is about 600 ms.

After turning on the power of the UPDL equipment, the USG restores the cyclic transmission to the Generator, and the Generator to the cable of the telegram, which he transmitted before turning off the power.

The UPDL used the same KI-6M information concentrator as in the automated workplace of the timber processing complex KTSM-01D. USG is a microprogram device functionally consisting of two modem nodes, an ID-D2 sensor signal processing unit, and a central processor.

The use of a device for transmitting data to operational personnel via digital communication, ensuring redundancy of the data transmission channel to the timber processing complex and eliminating the human factor in controlling high-speed train movement modes, will allow maintaining a sufficient level of train safety even in the absence of radio communication with the locomotive crew or in case of failure of the main data transmission channel on the forestry complex.
