Description

The utility model relates to the field of railway automation and is intended for use in a locomotive motion control system.

The prior art device for setting the direction of motion of a locomotive, comprising a controller of the driver; it is known that the driver’s controller assigns control commands to the reversers, the control unit collector for collecting power circuits in the traction and braking modes, the control unit commander for attenuating the field of traction motors, the setpoint for traction and braking current settings, the speed setter (RU 95103018 A1, IPC ⁶ B60L 11 / 04, “Device for contactless control of the operation mode of traction electric motors of a diesel locomotive”, published on December 20, 1996). This device essentially does not block invalid commands. To eliminate unacceptable and dangerous modes of control of the direction of movement and traction drive, complex mechanical structures are used.

The closest analogue of the claimed object is a device for setting the direction of movement of a locomotive, containing a control unit of motion control commands, means for generating reverse control commands associated with actuators that convert the generated digital control commands into discrete signals for control circuits of the locomotive reversers, and means for determining the permissibility of the generated direction control commands (RU 100460 U1, IPC B60L 15/00 (2006.01), “Device for setting the direction of movement of the locomotive ”, published on December 20, 2010). The means of permissibility of the generated commands is connected with the traffic safety system, the on-board diagnostics system, the auto-driving system, the driver’s control panel calculator, and the shunt-emergency controller. Thus, in this device, information from various control and information systems is used to establish the admissibility of the generated commands, which requires a complex organization of the interconnections of the device elements and external systems of the locomotive, a complex processing procedure, and complications lead to a decrease in the reliability of the device.

The technical result, the achievement of which is aimed at creating this utility model, is to increase the reliability of the device when changing the direction of movement of the locomotive.

The technical result is achieved by the fact that a device has been developed for changing the direction of movement of a locomotive, comprising a control unit for motion control commands, means for generating reverser control commands associated with actuators that convert the generated digital control commands into discrete signals for reverser control circuits, means for determining the admissibility of generated commands direction changes associated with the reverse command generation tool orams, the commander of the motion control commands and, through the general information bus of the locomotive, with means for determining the locomotive's speed and an alternative means of specifying the direction control commands.

The drawing shows a block diagram of a device for changing the direction of movement of a locomotive.

A device for setting the direction of motion of a locomotive comprises a command control unit 1, means for generating control commands for the reversers 2, connected with actuators 3, which convert the generated digital commands into discrete signals for control circuits of the locomotive reversers. The device comprises means for determining the permissibility of generated commands for changing the direction of movement 4, associated with means for generating commands for controlling the reversers 2, the master of the commands for controlling the movement 1 and, through the general information bus 5 of the locomotive, with means for determining the speed of the locomotive 6 and an alternative means for specifying commands for controlling the direction of movement . 7 ”

Commands to control the direction of movement (reversers) are received from the command initiator 1 to the means 2. Via the digital interface to the same means, information on the locomotive's speed from means of determining the speed is received through the general information bus 5 of the locomotive. Reverse control commands are generated by means of 2 according to a predetermined algorithm. At the same time, in order to avoid countercurrents on traction engines, a change in the direction of movement of the locomotive is allowed only after it has completely stopped, that is, at zero speed. The generated commands for controlling the direction of movement are entered into actuators 3, where they are converted into discrete and analog signals of high switching ability for relay control circuits of a locomotive. At the same time, the generated reports on the execution of the received commands, reports on the reasons for the refusal to execute the commands and the results of the device’s self-diagnosis are transmitted to the general information network of the locomotive.

To increase the survivability of the locomotive, the device provides the ability to back-up commands into the tool 2 in case of failure of the setter 1 .. In this case, the commands for controlling the direction of movement are formed as an alternative, which is any external device relative to the claimed device, for example, a control panel calculator , and they arrive at means 2 directly from the common information bus 5. The algorithm for blocking invalid commands remains unchanged.
