Problems solved by technology

[0011] Aiming at the menu structure business process existing in the menu generation scheme based on LCD screen in the prior art, the menu page design is integrated into the menu page design, and the software architecture of the menu page is not clear, which leads to high complexity and difficulty in adding, deleting, and modifying the menu page, and menu page switching To deal with the technical problems of complex procedures, long time consumption, and difficult maintenance in the later stage, the present invention provides a method and device for generating menus based on LCD screens, which can quickly build menus on dot-matrix LCD screens, and realize the separation of business processing and user interface design , The character code is separated from the menu structure, which is convenient for adding, deleting and modifying menu options. The software structure is clear and easy to maintain

Embodiment 1

[0063] Please refer to figure 1 , the embodiment of the present application provides a liquid crystal screen-based menu generation method, including the following steps:

[0064] S1. According to a unified page display style, generate a plurality of page units corresponding to a plurality of menu pages; wherein, each page unit includes static text, dynamic data, initialization function and operation function;

[0065] S2. Assigning a unique page ID to each menu page, and uniformly managing the multiple page units based on the page ID;

[0066] S3. When displaying the menu page, send the display content of the current page unit corresponding to the current menu page to the LCD screen based on the current page ID, so that the LCD screen displays the current menu page based on the received display content of the current page unit.

[0067] In the specific implementation process, the static text is used to display the status information of the menu page, and supports internationa...

Embodiment 2

[0080] Based on the same invention concept, please refer to image 3 , the embodiment of the present application also provides a liquid crystal screen-based menu generation device, including:

[0081] The page unit generation module 31 is used to generate a plurality of page units corresponding to a plurality of menu pages according to a unified page display style; wherein, each page unit includes static text, dynamic data, initialization function and operation function;

[0082] A page unit management module 32, configured to assign a unique page ID to each menu page, and uniformly manage the multiple page units based on the page ID;

[0083] The menu page generation management module 33 is used to send the display content of the current page unit corresponding to the current menu page to the liquid crystal screen based on the current page ID when the menu page is displayed, so that the liquid crystal screen is based on the current page unit received. The display shows the c...

Abstract

The invention discloses a liquid crystal display based menu generation method and device, and belongs to the technical field of human-computer interaction. The menu generation method includes the steps: S1, generating a plurality of page units which are corresponding to a plurality of menu pages one-to-one, according to a unified page display style, wherein each page unit includes a static text, dynamic data, an initialization function, and an operation function; S2, distributing a unique page ID to each menu page, and uniformly managing the plurality of page units based on the page ID; S3, sending display content of a current page unit corresponding to a current menu page to the liquid crystal display based on a current page ID during displaying of the menu pages so as to allow the liquid crystal display to display the current menu page based on the received display content of the current page unit. A menu of a lattice liquid crystal display can be quickly established; menu service treatment and user interface design are separated; adding, deletion, and change of menu options are facilitated; and a software architecture is clear and is easy to maintain.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction based on a liquid crystal screen, in particular to a method and device for generating a menu based on a liquid crystal screen. Background technique [0002] LCD (Liquid Crystal Display) liquid crystal display is widely used in industrial control, especially the man-machine of some machines, the panel of complex control equipment, the display of medical equipment and so on. LCD is used as an interface between users and equipment, and can be used to display real-time information and set system parameters. [0003] LCD can be divided into three types from the display mode: segment type, character type and dot matrix type. At present, LCD dot-matrix liquid crystal screens have been used in monitoring systems in the power electronics industry. LCD dot-matrix liquid crystal screens include two types: negative codes and positive codes. The bright spot of the dot matrix LCD screen is ...
