Problems solved by technology

Pointer instruments have defects such as low display accuracy and weak anti-interference ability; although digital instruments have improved display accuracy and anti-interference ability, they cannot provide range display well (for car drivers) It is very important to know these contents), the display is tedious, and the car driver is prone to fatigue and other defects; also because of the various defects of the digital instrument, the pointer instrument is used more now.
And above-mentioned two kinds of automobile instrument generally are a kind of instrument displaying a kind of parameter, so also there is the defective of aspects such as complex manufacturing process of whole automobile instrument, process equipment is many, especially need to provide the automobile of multi-parameter combination display, have to add more More display devices make this defect more prominent

Embodiment 1

[0033] (1) Overall composition:

[0034] see figure 1 , a digital graphic automotive instrument, comprising a processor 1, a memory 2, a parameter acquisition module 3, a display driver module 4, a display panel 5, and software are functional modules stored in the memory, wherein:

[0035] Processor 1: Embedded processor with low power consumption, 32-bit or more and with real-time interrupt function (processor is the core of digital graphic car instrument, it will affect every aspect of the whole design, choose A good processor is very important, you must choose a processor that meets the design requirements in all aspects, and generally do not choose a processor lower than 32 bits);

[0036] Memory 2: including RAM and ROM. ROM is used to store software and data, that is, to store functional modules. The most suitable type of ROM (including ordinary ROM, EEPROM, Flash Memory, etc.) should be selected according to the purpose of the stored data. In a The system can use a va...

Embodiment 2

[0067] This embodiment is that on the basis of embodiment 1, the user input button 6 and the sound output driver module 7 have been added, and an interrupt processing program module (processing user input data), a graphic selection program module (such as this digital graphics A variety of display graphics can be stored by simplifying the car instrument).

[0068] (1) Overall composition:

[0069] see image 3 , including a processor 1, memory 2, parameter acquisition module 3, display driver module 4, display panel 5, user input buttons 6, sound driver module 7 and software that is a functional module stored in the memory, wherein:

[0070] User input button 6: used for user input data;

[0071] Sound driver module 7: sound output, including alarm sound, etc.;

[0072] The function modules stored in the memory are the required software: including parameter sampling program module, dynamic graphic construction program module, graphic combination program module, control prog...

Abstract

The digital graphic automobile instrument includes processor, memory, parameter acquiring module, displaying and driving module, display panel and functional modules stored in the memory. The functional modules include parameter sampling program module, graph displaying program module, graph data module, and control program module. By means of computerized digital graph processing technology and embedded computer software technology, the present invention displays and records parameters graphically on automobile display panel, and realizes hardware function with software. The present invention has the features of rich display colors, high display precision, high reliability, etc. and can show speed, mileage, engine rotation speed, water temperature, oil amount and other parameters in the panel.

Description

technical field [0001] The invention relates to a novel automobile instrument, in particular to a digital graphic automobile instrument displaying parameters in a graphic manner. Background technique [0002] There are two main types of automotive instrumentation systems currently in use, one is a pointer instrument displayed in an analog mode, and the other is a digital instrument displayed in a digital mode, and these two types of instruments have different defects. Pointer instruments have defects such as low display accuracy and weak anti-interference ability; although digital instruments have improved display accuracy and anti-interference ability, they cannot provide range display well (for car drivers) It is very important to know these contents), the display is tedious, and the car driver is prone to fatigue and other defects; also because of the various defects of the digital instrument, the pointer instrument is more used now. And above-mentioned two kinds of auto...
