Problems solved by technology

[0002] The predecessor of the LKJ15 system is the LKJ2000 train control system. The LKJ2000 system adopts the main-standby redundancy technology, and the main mode is fixedly displayed. There is no simultaneous operation of 4 modes, and the driver cannot obtain effective information of the locomotive in time.

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 Shown is the system structure diagram of the train control system of the present invention. Including the host unit and the man-machine interface unit, in which the host unit adopts 2 x 2 out of 2 hot standby redundancy, including I series host system and II series host system, and each series host system includes two A-mode CPUs working at the same time and B-mode CPU; the man-machine interface unit adopts four-mode cold standby redundancy at both ends, including Ⅰ series DMI and Ⅱ series DMI, each series DMI includes two human-computer interaction units, and each human-computer interaction unit includes a CPU , the four-mode CPU of the host unit is connected with the CPU of each human-computer interaction unit.

[0025] Specifically, the above-mentioned human-machine interface unit (DMI) adopts 2-terminal 4...

Abstract

The invention provides a train control system and a train control system four-mode switching display method. In a host unit with double 2-vote-2 hot standby redundancy and a main control system with two-end quadruple modular redundant, a method for selecting a current display mode of a human-computer interface unit through switching comprises the steps of (1) receiving that a host unit informationtransmitter is used as a mode currently displayed on a human-computer interaction interface first when the human-computer interface unit is just electrified; setting the priorities of the following parameters from low to high: shorter distance, minimum speed limiting-time speed difference, alarming prompting and braking output; and according to a sequence from the low priority to a high priority,performing switching displaying according to the priority sequence. According to the train control system and the train control system four-mode switching display method, effective information can bedisplayed on a DMI interface in a more timely manner to be more beneficial for driver operation.

Description

technical field [0001] The invention relates to a display method of a train control system, in particular to a four-mode switching display method of the train control system. Background technique [0002] The predecessor of the LKJ15 system is the LKJ2000 train control system. The LKJ2000 system adopts the main-standby redundancy technology and displays the main mode fixedly. There is no simultaneous operation of 4 modes, and the driver cannot obtain effective information of the locomotive in time. Contents of the invention [0003] Based on the display defects of the existing LKJ15, the present invention provides a method capable of performing 4-mode switching display to solve the problems existing in the prior art. [0004] The present invention adopts following technical scheme: [0005] A train control system, including a host unit and a man-machine interface unit, the host unit adopts 2 x 2 out of 2 hot standby redundancy, including a series I host system and a serie...
