Full-liquid-crystal automobile combination meter and system control method of full-liquid-crystal automobile combination meter

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 automobile combined meters, in particular to a full liquid crystal automobile combined instrument and a system control method thereof. Background technique [0002] As an automotive electronic product with particularly high requirements for safety and reliability, automotive combination meters are used to display various performance states of the car, and are an important source of information for drivers to obtain vehicle status. The automobile combination instrument is composed of various instruments and indicators, especially the warning indicator light for the driver, which provides the driver with the required automobile operating parameter information. With the development of automotive electronic technology and consumers' increasingly critical vision, automotive instrument clusters have experienced a development process from traditional mechanical movement watches and electrical instruments to fully int...
