Abstract

The invention relates to the technical field of automobile instruments, and provides an automobile virtual instrument based on embedded Linux. The automobile virtual instrument comprises a signal acquisition unit, an embedded processor, a virtual instrument and an alarm module, wherein the signal acquisition unit acquires all kinds of state information of an automobile, the state information is transmitted to the embedded processor through a conversion processing module, the virtual instrument dynamically displays the processed data by adopting a QT design soft panel, the alarm module is usedfor giving a prompt alarm when any one abnormal state exists, the alarm module is internally provided with a voice chip, and the virtual instrument is composed of a hardware system and a software system. The virtual instrument has good readability, high reading precision, good improvement in portability, maintainability and cost aspects, and great scientific research value and commercial use value.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to an automobile virtual instrument based on embedded Linux. Background technique [0002] As a very important part of the whole system of the car, the instrument is one of the important aspects to improve the overall performance of the car. With the rapid development of computer software and hardware technology, bus technology, electronic technology, etc., the traditional electromagnetic mechanical instruments with bloated control system, complicated wiring and large space occupation are gradually being eliminated, and virtual instruments are developing rapidly at a speed unmatched by traditional mechanical instruments. . At present, virtual instruments usually include two types: pure digital instruments and virtual dashboard instruments: pure digital instruments are relatively low in cost, but their functions and interfaces are relatively simple, which cannot meet ...
