Vehicle-mounted remote terminal supporting multi-network sharing

Abstract

The invention discloses a vehicle-mounted remote terminal supporting multi-network sharing. The vehicle-mounted remote terminal is composed of a microprocessor module, a 4G wireless communication module, a BD / GPS positioning module, a WiFi module, a Bluetooth module, a radio module, an NFC chip, a six-axis sensor, a battery and management module, a data memory, a mobile TV module, a CAN transceiver, a CAN controller, a voice output / input module, an indicator light, an interface circuit and a button module. The microprocessor serving as a data and information processing core is connected with all sub modules and controls function calling of all sub modules. The battery and management module consists of a built-in battery and a management module; the built-in battery is used for ensuring normal working of the vehicle-mounted terminal when power of the vehicle is interrupted; and when the vehicle is started normally, the power of the vehicle-mounted terminal is provided by a vehicle engine. The CAN transceiver and CAN controller are used for realizing communication between the intelligent vehicle-mounted terminal and the whole vehicle network.

Description

technical field [0001] The invention relates to a vehicle-mounted remote terminal, in particular to a multifunctional intelligent vehicle-mounted terminal based on an Internet vehicle. Background technique [0002] With the increasing popularity of automobiles, consumers' demand for automobiles has gradually shifted from traditional economy, handling and comfort to intelligence, infotainment, security control, etc. Consumers generally have higher requirements for the technological level of in-vehicle electrical appliances. [0003] The current networked vehicle products are mainly used to provide real-time traffic information for the navigation system. They only support mobile devices in the vehicle to access the network through WiFi. There is no product with a high degree of integration. This product can realize vehicle network security, vehicle security control, In-vehicle entertainment network interconnection, time-sharing leasing and other functions truly effectively lin...

AI Technical Summary

Problems solved by technology

Some newly developed on-board OBD devices (On Board Diagnostics on-board automatic diagnosis system) can obtain vehicle information through the CAN bus, and realize some functions of interacting with vehicle information (such as remote diagnosis and remote control). Car safety performance has great potential safety hazards

Some newly developed in-vehicle communication modules, based on CAN bus and 2G / 3G network, can perform security and remote control of vehicles through wireless networks, and can share network channels for in-vehicle device networking, but the in-vehicle communication module only acts as an in-vehicle gateway and The function of the wireless router cannot interact with the entertainment system

[0004] Part of the vehicle-mounted equipment integrates all the functions of the vehicle-mounted communication module into the host of the entertainment system, which results in a large number of functions of the hardware equipment, which is not conducive to subsequent function upgrades and design changes. Promoted on mass-produced models
