Embodiment Construction

[0028] Such as figure 1 Shown, method step of the present invention is as follows:

[0029] 1) Start: system initialization, communication initialization, interface initialization, timer initialization;

[0030] 2) Determine whether the timer execution period has arrived, if so, go to 3); if not, wait for the timer interrupt;

[0031] 3) Determine whether the interface has been defined, if it has been defined, preprocess the control properties in the existing interface, and correspond to the predefined variables in the program one by one; if the interface has not been defined, define the uninvolved interface, and then preprocess The control properties in the existing interface correspond to the predefined variables one by one;

[0032] 4) Establish the data structure of the program corresponding to the interface control: take the interface as a unit, define each interface as a corresponding structure variable, and establish a structure variable with unified characteristics; ...

Abstract

The invention discloses a display interface data treatment method and a platform based on a middle piece, mainly provides a novel platformization train display interface data treatment method and is suitable for developing of intelligent man-machine interaction interface application systems of control systems of varied train models. A middle piece is used as a bridge between train terminal display equipment and a rear end data signal collection system. A C++ or C language is used to program a large program module which serves as a port between a train display interface and the signal control system so as to achieve platformization in developing display application systems. The display interface data treatment method achieves platformization in developing the display application systems, reduces a working load and improves efficiency of applying and developing a train display and is strong in transportability.

Description

technical field [0001] The invention relates to a communication data processing method, in particular to a middleware-based display interface data processing method and platform. Background technique [0002] With the rapid development of railway construction, the types of train vehicles are also increasing. No matter what type of vehicle is, the train intelligent display is indispensable. The driver uses the display to understand the information of the various systems and equipment on the train. The display device has become a train network control system and An important part of the information system, it is mainly responsible for the display of train status information, and serves as an intelligent human-computer interaction interface for the train control system. [0003] At present, the operating system platform used in the development of display application software is embedded Linux, and the GUI tool set is FLTK. Linux is a set of unix-like operating systems that are...
