Intelligent vehicle-mounted interconnection system

Abstract

The invention discloses an intelligent vehicle-mounted interconnection system, which comprises a host, a DSP module, an audio / video playing system, a USB interface module, a mobile broadcasting module, a voice recognition module, a mobile communication module, an audio power amplifier module and a TBOX, and is characterized in that the voice recognition module, the mobile communication module andthe audio power amplifier module are connected with an SOC chip in the host; wherein the voice recognition module comprises a microphone array, the audio power amplifier module uses an in-vehicle sound system as a loudspeaker, the voice recognition module transmits voice signals collected by the microphone array to the DSP module for processing through an A2B protocol, and the processed audio signals are transmitted to the SOC chip or voice information received by the SOC chip is sent to the audio power amplifier module; the audio / video playing system comprises an audio / video playing device and a storage unit which are connected with the SOC chip through a USB interface module. The intelligent vehicle-mounted interconnection system comprises a radio antenna connected with the SOC chip, andthe radio antenna receives a mobile broadcast signal, modulates the mobile broadcast signal through Radio Tuner and transmits the mobile broadcast signal to the DSP module.

Description

Technical field: [0001] The invention relates to an intelligent vehicle interconnection system, which belongs to the technical field of car audio entertainment systems. Background technique: [0002] Nowadays, with the rapid development of automotive electronic technology, the vehicle interconnection system is gradually becoming the focus of attention of automobile manufacturers and users, but we can see that the current vehicle system has small screen, low resolution, running lag, and high network delay. , inaccurate navigation, low voice recognition rate, unsmooth human-vehicle interaction, and in-vehicle systems failing to network with other facilities. 4G and GPS + inertial navigation module and 12.8-inch large screen are integrated into the car to create a fully functional intelligent vehicle interconnection system including vehicle communication system, vehicle network, vehicle navigation, vehicle control, vehicle entertainment system, etc. Invention content: [000...

Problems solved by technology

[0002] Nowadays, with the rapid development of automotive electronic technology, the vehicle interconnection system is gradually becoming the focus of attention of car manufacturers and users, but we can see that the current vehicle system has small screen, low resolution, running lag, and high network delay. , inaccurate navigation, low voice recognition rate, unsmooth human-vehicle interaction, in-vehicle system failure to network with other facilities, etc. Most of the in-vehicle system functions are relatively limited, so we use the car-grade IMX8QXP chip, Android 9.0 operating system, 4G and GPS + inertial navigation module and 12.8-inch large screen are integrated into the car to create a fully functional intelligent vehicle interconnection system including vehicle communication system, vehicle network, vehicle navigation, vehicle control, vehicle entertainment system, etc.
