Problems solved by technology
This technology is only suitable for portable devices such as mobile phones or wristbands. On sports vehicles or boats, detecting vibration can easily lead to false triggers, which cannot be effectively realized.
[0004]
By combining the car map to set the starting point and calculate the average speed, and calculate the positioning information through software, this patent can achieve the purpose of saving power, but it cannot solve the positioning after emergencies, and the positioning information has low reliability and low security.
The existing technology only has two states of continuous on and off of GPS. If the vehicle is in the case of a ferry (that is, the vehicle changes its position, and the existing technology may miss detection), the existing GPS power-saving solution will appear Positioning failed

The invention provides a method and a system for reducing power consumption based on GPS electronic equipment. The method comprises the steps: detecting a driving speed at regular time, and determining a speed gear corresponding to the driving speed according to the driving speed; and adjusting a GPS switching proportion and a CPU main frequency according to the speed gears so as to reduce the power consumption. According to the method and the system for reducing the power consumption based on the GPS electronic equipment provided by the embodiment of the invention, the time proportion of opening and closing of a GPS module can be dynamically adjusted in real time according to the driving speed condition fed back by the electronic equipment, the reliability and the stability of positioninginformation are ensured, and meanwhile, the purposes of saving power and reducing the power consumption are also achieved.
Description
technical field [0001] The present invention relates to the technical field of power consumption and energy saving, and more specifically, to a method and system for reducing power consumption of GPS-based electronic equipment. Background technique [0002] At present, the technologies for reducing power consumption and saving power of GPS devices mainly include: [0003] The vibration is detected by the sensor to realize the switch of GPS. This technology is only suitable for portable devices such as mobile phones or wristbands. On sports vehicles or boats, detecting vibrations may easily lead to false triggers, which cannot be effectively realized. [0004] By combining the on-board map to set the starting point and calculate the average speed, and calculate the positioning information through software, this patent can achieve the purpose of saving power, but it cannot solve the positioning after an emergency, and the positioning information has low reliability and low se...
