Abstract

The invention discloses a WIFI (Wireless Fidelity) upgrading method and apparatus for an operation system of a vehicle-mounted terminal. The upgrading method comprises the steps that an MIPS (Million Instructions Per Second) establishes a wireless connection with an intelligent terminal storing operation system upgrading files through a WIFI unit; the MIPS sends an upgrading request message to the intelligent terminal for enabling the intelligent terminal to send the operation system upgrading files to the MIPS; the MIPS receives and judges whether an operation system upgrading file for the MIPS and an operation system upgrading file for an MCU (Micro Control Unit) exist in the operation system upgrading files or not; if the operation system upgrading file for the MIPS exists, the MIPS enters an upgrading mode and an operation system of the MIPS is upgraded according to the operation system upgrading file for the MIPS; and if the operation system upgrading file for the MCU exists, the operation system upgrading file for the MCU is sent to the MCU and the MCU is triggered to enter the upgrading mode for enabling the MCU to upgrade an operation system of the MCU according to the operation system upgrading file for the MCU.

Description

technical field [0001] The invention relates to the field of Internet information technology, in particular to a WIFI upgrading method and device for a vehicle-mounted terminal operating system. Background technique [0002] The vehicle-mounted terminal, also known as the vehicle dispatching and monitoring terminal, is the front-end equipment of the vehicle monitoring and management system. It integrates multiple functions such as positioning, communication, and vehicle driving recorder. monitoring platform. Users can monitor and manage vehicles through intelligent terminals such as computers and mobile phones. [0003] At present, when the operating system of the vehicle-mounted terminal needs to be upgraded, the serial port of the vehicle-mounted terminal is generally used for upgrading. The specific upgrading process is as follows: connect the serial port of the vehicle-mounted terminal to a smart terminal equipped with an operating system upgrade file, and the smart ter...
