Embodiment 1

[0046] see figure 1 , is a schematic diagram of the framework of the digital meter pointer display system of the embodiment; the digital meter pointer display system provided by the present invention, the basic structure of the display implementation is to split the application window into two parts:

[0047] 1. The pointer window is implemented using the OpenGL interface.

[0048] 2. Ordinary windows (dials, texts, icons) are implemented using the Qt GUI framework.

[0049] As shown in the table below:

[0050]

[0051] according to figure 1 The display order of the windows in : the pointer window is in the front, and the normal window is in the back. After being synthesized by the GPU, it is displayed as a complete image.

[0052] figure 2 It is a schematic structural diagram of a digital instrument pointer display system according to an embodiment of the present invention. The present invention provides a digital meter pointer display system, said system comprising...

Embodiment 2

[0065] In addition, the present invention also discloses a digital meter pointer display method based on the digital meter pointer display system, such as Figure 4 As shown, it is a flowchart of a digital instrument pointer display method according to an embodiment of the present invention;

[0066] The method comprises the steps of:

[0067] Step 1: Initialize the pointer window;

[0068] Step 2: Query the data interface message to determine whether there is new pointer movement boundary value setting data, if so, go to step 3, otherwise go to step 4;

[0069] Step 3: updating the pointer movement boundary value according to the new pointer movement boundary value setting data;

[0070] Step 4: Determine the current pointer movement state, if the current pointer is in a stopped state, then go to step 2, otherwise go to step 5;

[0071] Step 5: redraw the pointer to a new position according to the pointer motion state and the pointer motion boundary value;

[0072] Step 6...

Abstract

The invention relates to the field of digital instruments, provides a digital instrument pointer display system, and additionally further provides a digital instrument pointer display method. The digital instrument pointer display system is characterized in that the digital instrument pointer display system comprises a pointer window, an ordinary window, a GPU module and a data interface; the datainterface is used for transmitting and receiving external data, and the pointer window is used for displaying the engine rotating speed and the automobile speed according to the data received by thedata interface; and the ordinary window is used for displaying a dial plate, ordinary texts and icons, and the GPU module composites the pointer window and the ordinary window in the order that the pointer window is located in front of the ordinary window and displays a complete digital instrument image. The digital instrument pointer display system achieves the effects that the instrument pointerdisplay accuracy is high, the response real-time performance is high and the visual fluency is high.

Description

technical field [0001] The invention relates to digital instrument technology, in particular to a digital instrument pointer display system and method. Background technique [0002] With the continuous advancement of modern technology, electronic products have been widely used in automobiles and are gradually becoming more intelligent. At present, most of the most common automobile instruments use electromechanical combination instruments. As the information displayed on the instrument panel continues to increase, causing The panel area of ​​the combination instrument is increasing continuously, but the display capability of the existing electromechanical combination vehicle instrument panel in actual application is limited, which cannot meet the increasing needs of vehicle information processing and display. Traditional automotive instrumentation is mainly for some parameters of fuel vehicles, including display and alarm for related information such as fuel volume, oil temp...
