Embodiment

[0028]referencefigure 1 , The signal information processing module 1 periodically calculates the device status of each signal device and sends it to the intermediate conversion module 2. The intermediate conversion module 2 converts the device status of each signal device into one or more corresponding graphic element display characteristics The value is sent to the signal information display module 3; the signal display module displays the characteristic value according to the graphic element, and displays the specific graph on the screen.

[0029]referencefigure 2, Give an example of the processing flow when the intermediate conversion module 2 receives the signal state (such as positioning occupied, not single-locked, blocked) of a signal device (such as switch P05D):

[0030]Step 101: The signal status received from the switch P05D is statusNew: positioning occupied, not single-locked, not blocked, and not speed limited. Use the switch name P05D to search in the cache data structure i...

Abstract

The invention relates to a device and method for dynamically controlling multi-standard railway signal display graphic symbols. The device includes a signal information processing module, an intermediate conversion module and a signal information display module connected in sequence. The signal information processing module calculates each The device state of the signal device is sent to the intermediate conversion module; the intermediate conversion module converts the device state of each signal device into a corresponding graphic element display characteristic value, and sends it to the signal information display module; the signal display module Display characteristic values ​​according to primitives, and display specific graphics on the screen. Compared with the prior art, the invention has the advantages of low coupling of software function modules, low software development and maintenance costs and the like.

Description

Technical field[0001]The invention relates to the technical field of railway signal information, in particular to a device and method for dynamically controlling railway signals to display graphic symbols.Background technique[0002]At present, railway signal screens in different countries or regions have different standards for displaying graphic symbols, and different railway signal operating companies have different requirements for the specific details of the same signal display. At present, the common solution is to design different monitoring terminal software products, and use corresponding products to achieve specific implementation according to user requirements. The defects are as follows:[0003]1. Poor product compatibility. When a signal display processing algorithm is updated, all software products need to be upgraded.[0004]2. Poor project implementation. After the user changes the specific needs of a certain signal display, he needs to upgrade the specific functions of hi...
