Problems solved by technology

However, the virtual instrument implementation method designed by ARM+Android has the following defects: the dynamic way of virtual instrument pointer movement is difficult to realize, and the pointer is rigid and has a poor sense of reality; When changing the position of the dial, the program of the graphical interface is difficult to reuse
In addition, the use of ARM+Android design scheme also has low development efficiency, high development difficulty, and unsightly graphical interface, which makes it difficult to meet the needs of various high-end consumer groups for virtual instrument experience.
If the virtual instrument designed by ARM+Linux+MiniGUI or ARM+Linux+QT will have the following defects: (1) Because the tools developed by the graphical interface need to charge software usage fees, the technical cost is relatively high
(2) The graphical interface is not based on vector graphics. The developed program is large, and it will be distorted when zooming in or out. Therefore, when changing the screen size or changing the position of the dial, the graphical interface program also has the problem of being difficult to reuse
(3) The designed graphical interface of the virtual instrument is not beautiful enough, and high-end consumer groups have demand for virtual instrument experience
If the virtual instrument designed with PC+Windows+LabVIEW has the following defects: LabVIEW is only for virtual instruments, and all instruments are packaged on the control
In application, although developers can change the expression form of related controls according to requirements, they cannot design the interface of the instrument completely freely, and its graphical interface is also not beautiful enough.

example 1

[0020] Example 1 is that the operating program of the present invention is as follows:

[0021] package {

[0022] \\Other loader packages

[0023] \\Flash interacts with other containers

[0024] Import flash.external.ExternalInterface;

[0025] public class main extends MovieClip \\ class that defines the fal file (flash stage)

[0026] {

[0027] \\Define main class private constants, variables, method functions, etc.

[0028] \\Pointer movement method function

[0029] private function ChangeNeedleAngle(): void

[0030] {

[0031] / / Calculate what angle the pointer needs to move to

[0032] / / Pointer movement target angle = offset angle of real-time data relative to scale 0;

[0033] / / Control the pointer not to spin around

[0034] if(pointer current angle>=-180 &&pointer current angle<0)

[0035] {

[0036] Pointer movement target angle = pointer movement target angle - 360;

Abstract

The invention discloses a virtual instrument based on a flash graphic interface. Including hardware platform and virtual instrument software. Among them, the hardware platform includes system core CPU module, analog sampling module, USB driver module, serial port communication module, CAN communication module, LCD driver module, system power supply module, input and output module, touch driver module, memory module, memory. The virtual instrument software is encapsulated in the core CPU module of the system. The virtual instrument software includes the operating system part encapsulated in the core CPU module of the system, the background container application program part, and the Flash graphical interface embedded in the background container application program part. The present invention has the effect of real-time graphical interface and 2D or 3D animation display, self-definition of interface definition and package development, and easy replacement of display content or changing display style.

Description

technical field [0001] The invention belongs to the field of automobile auxiliary equipment, in particular to a virtual instrument based on a flash graphic interface. Background technique [0002] At present, the instruments traditionally used in automobiles are mainly mechanical pointer instruments. The full LCD virtual instrument system that is now appearing has also begun to be gradually applied to high-end models. When in use, the function of a traditional instrument is completed in the form of a virtual pointer instrument on a large-size LCD screen. The displayed content has become more abundant, and can be dynamically adjusted according to the driver's needs and actual vehicle conditions, and can display car audio and video, reversing images, map navigation and other content. Typical high-end models such as Land Rover, BMW, Cadillac and Jaguar. Aiming at the development trend of full liquid crystal virtual instrument, many automobile manufacturers at home and abro...
