Embodiment 1

[0024] The embodiment of the present invention provides a vehicle track circuit signal display, such as figure 1 As shown, the display includes: a power supply module 101, a first control module 102, a second control module 103, a display driver module 104, a display module 105 and an output feedback module 106; wherein,

[0025] The power supply module 101 is used to supply power for the on-board track circuit signal display;

[0026] The first control module 102 is configured to process the received data and output display data to the display driver module;

[0027] The second control module 103 is configured to process the received data, and output a display control command to the display driver module;

[0028] A display driver module 104, configured to drive the display module to work according to the display data and display control commands;

[0029] Display module 105, used to realize the display of track circuit information;

[0030] The output feedback module 106 ...

Embodiment 2

[0033] The embodiment of the present invention further describes in detail the vehicle-mounted track circuit signal display disclosed in Embodiment 1. Specifically, the first control module and the second control module in the vehicle-mounted track circuit signal display are respectively connected to the two main boards in the host , that is, the first control module corresponds to motherboard A and is used to receive data from motherboard A, and the second control module corresponds to motherboard B and is used to receive data from motherboard B; the first control module and the second control module The output terminals of the module are respectively connected to the display driver module, the display driver module is connected to the display module, and the display driver module drives the display module to display according to the output of the first control module and the second control module; meanwhile, the output feedback module is also connected to the display module, ...

Embodiment 3

[0063] The embodiment of the present invention also provides a safety control method for the vehicle track circuit signal display, such as Figure 4 As shown, the method includes:

[0064] S1: The on-board track circuit signal display independently receives two channels of data, and independently processes the two channels of data;

[0065] S2: The on-board track circuit signal display judges whether display data and display control commands are obtained;

[0066] If not, or only one of them is obtained, no information will be displayed;

[0067] If so, display the display data to realize the display of track circuit information;

[0068] S3: The on-board track circuit signal display receives the feedback information and processes it.

[0069] Specifically, the safety control method of the vehicle-mounted track circuit signal display provided by the embodiment of the present invention is realized by the first control module, the second control module, the display drive modu...

Abstract

The invention discloses a vehicle-mounted track circuit signal display and a security control method thereof. The vehicle-mounted track circuit signal display comprises a power supply module, a first control module, a second control module, a display driving module, a display module and an output feedback module, wherein the power supply module is used for supplying power to the vehicle-mounted track circuit signal display; the first control module is used for processing received data and outputting the displayed data to the display driving module; the second control module is used for processing the received data and outputting a display control command to the display driving module; the display driving module is used for driving the display module according to the displayed data and the display control command; the display module is used for realizing display of track circuit information; and the output feedback module is used for feeding back the content displayed by the display module to the first control module and the second control module. With the adoption of the display and the security control method provided by the invention, the requirements on safe and reliable display of high speed trains are met; the display is small and exquisite; and meanwhile the display security is ensured through the first control module and the second control module; and the reliability is improved through the output feedback module.

Description

technical field [0001] The invention relates to the field of train driving safety, in particular to a vehicle-mounted track circuit signal display and a safety control method thereof. [0002] Background technique [0003] The on-board track circuit signal display is installed in the cab of the locomotive. It is an important part of the on-board track circuit signal receiving system. Obtain the target speed of the train and the state of the line ahead of its operation, and provide the corresponding reference basis for traffic control. At the same time, the use of the on-board track circuit signal display can also effectively improve the working conditions of the locomotive crew and avoid the influence of weather factors such as rain, snow, and haze. [0004] However, the current on-board track circuit signal display still uses the traditional light position display method, which can only display 8 different fixed light information. With the development of the railway, its ...
