Problems solved by technology

Traditional GUIs are generally implemented based on desktop computers, which support complex window and control management and clipping algorithms, and require a lot of hardware resources and CPU load
In order to save costs, the hardware resources of relay protection devices are very limited; and in order to meet the strong real-time requirements of relay protection actions, the CPU load is heavy, so the conventional GUI is difficult to apply to relay protection devices

Embodiment Construction

[0063] refer to figure 1 , The liquid crystal interface display software of the present invention includes liquid crystal interface design software and execution software, the execution software includes a GUI module and an application layer, and the GUI module includes a driver abstraction layer, a basic support environment, and a window management system. The window interface, control layout, character string and other information are designed by the liquid crystal interface design software, and the interface parameter file is generated. Then the execution software analyzes the interface parameter file, and draws and manages information such as windows, controls, and character strings on the LCD. The execution software is the core module of the whole system, organized in a hierarchical architecture, including GUI modules and application layers. The GUI module is used to implement the basic features of the GUI. The driver abstraction layer extracts various hardware features...

Abstract

The invention discloses a realizing method for liquid crystal interface relay protection. The method comprises steps as follows: designing liquid crystal interface; generating a liquid crystal parameter file and transmitting the parameter file to a relay protection device; analyzing the parameter file through the relay protection device to construct an internal data structure; managing system messages and generating a message queue; a message passing stage; a message handling stage for executing all sorts of message handling functions corresponding to the messages. The realizing method for liquid crystal interface supports a window, control and a stack frame in a GUI model, encodes and escapes a character string and a word stock, occupies small resource, has quick response speed, and is suitable for a relay protection system with limited resource and high CPU load.

Description

technical field [0001] The invention relates to a method for realizing a liquid crystal interface, in particular to a method for realizing a liquid crystal interface for relay protection. Background technique [0002] With the rapid development of power system relay protection, there are more and more functions, and the operation is more and more complicated. In order to facilitate the user's operation, not only a liquid crystal with a large size and a high dot matrix is ​​required, but also a flexible and convenient operation method is required. Due to the limitation of hardware resources, the traditional LCD interface program implementation method mixes functions such as LCD drawing, key processing, Chinese character library, relay protection, etc., which makes the implementation complicated, poor in operation flexibility and slow in response. [0003] The development of the computer industry has proved that the use of GUI can simplify interface programming and user opera...
