System control method of full liquid crystal automobile combination instrument

Abstract

The invention discloses a full-liquid-crystal automobile combination meter and a system control method of the full-liquid-crystal automobile combination meter. The full-liquid-crystal automobile combination meter comprises an MCU, a signal access module, an LED display module, a voice frequency prompting module, an ARM kernel microprocessor, a TFT display module, a video transmission module and a network transmission module. The MCU, the video transmission module and the network transmission module are in both-way connection with the ARM kernel microprocessor, and the TFT display module is connected with the output end of the ARM kernel microprocessor. According to the full-liquid-crystal automobile combination meter and the system control method, the ARM kernel microprocessor is additionally arranged on the basis of a traditional meter, driving to the TFT display module and both-way information transmission of the video transmission module and the network transmission module are achieved, and the functions of playing animations and videos and conducting remote control and data transmission through the network by a user are achieved; UI displaying of the full-liquid-crystal combination meter is achieved, and the requirement of function expansion of the full-liquid-crystal combination meter is met; the full-liquid-crystal automobile combination meter integrates the functions of a traditional combination meter and the functions of a full-liquid-crystal virtual meter, and platformization of system developments of the combination meter is achieved.

Description

technical field [0001] The invention relates to the technical field of combination meters for automobiles, in particular to a system control method for a full liquid crystal combination meter for cars. Background technique [0002] As an automotive electronic product with particularly high safety and reliability requirements, the automotive instrument panel is used to display various performance states of the car, and is an important source of information for the driver to obtain the state of the vehicle. The car combination instrument is composed of various instruments and indicators, especially the driver's warning indicator light, which provides the driver with the required information of the car's operating parameters. With the development of automotive electronic technology and consumers' more and more critical eyes, the car combination instrument has experienced the development process from the traditional mechanical movement watch, electrical instrument to the fully i...
