A method for realizing low power consumption of equipment and vehicle-mounted terminal

Abstract

The present invention provides a method for realizing low power consumption of equipment and a vehicle-mounted terminal, wherein the vehicle-mounted terminal includes: a main controller, a main processor, and a wake-up module; after the vehicle is turned off, the main controller and the main processor enter dormancy state; the wake-up module is connected to the main controller, and is used to send a first wake-up signal to the main controller, so that the main controller is switched from a dormant state to a wake-up state; the main controller judges the The wake-up source corresponding to the first wake-up signal, and based on the wake-up source, generates a second wake-up signal and sends it to the main processor, so that the main processor switches from the sleep state to the wake-up state; the main processor determines the wake-up source based on the second wake-up signal , and execute the processing flow corresponding to the wake-up source, so that the entire system enters the wake-up state only when it needs to work, and is in a sleep state in other cases, which greatly reduces system power consumption.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method for realizing low power consumption of equipment and a vehicle-mounted terminal. Background technique [0002] With the popularization of the Internet of Vehicles, the application of vehicle-mounted terminals in vehicles is becoming more and more extensive. The vehicle-mounted terminal enables the vehicle to realize self-monitoring when no one is on duty. For example, in the event of a collision, robbery, etc., the scene can be recorded and the owner can be notified through the network; in addition, the owner can also remotely control the vehicle, such as going out in winter Start the vehicle remotely in advance, turn on the warm air in advance; turn on the air conditioner in advance in summer, which greatly improves the driver's driving experience. [0003] In order to achieve the above functions, the vehicle-mounted terminal needs to have the function of ...

AI Technical Summary

Problems solved by technology

[0003] In order to achieve the above functions, the vehicle-mounted terminal needs to have the function of detecting and receiving network signals when the vehicle is turned off and parked. During the parking period, the vehicle-mounted terminal is in the power-on state, and all functions are running normally. Running consumes a lot of battery power
