Abstract

The invention provides a low-power-consumption positioning method based on motion posture. The method includes the steps of informing a processor to perform related motion detection through a programmable interrupt output pin of an MEMS (Micro Electro Mechanical System) acceleration sensor, reading three-axis acceleration information from FIFO (First Input First Output) of the MEMS acceleration sensor, determining posture information according to the three-axis acceleration information and by combining with an appropriate algorithm, opening or closing a GNSS (Global Navigation Satellite System) module and a GSM (Global System for Mobile Communication) module according to the posture information, automatically adjusting positioning interval and uploading the interval to control power consumption to further achieve optimal use of battery power. The low-power-consumption positioning method based on motion posture can ensure positioning requirements and obtain longer using time through the limited battery capacity.

Description

technical field [0001] The invention relates to a navigation and positioning system, in particular to a low-power consumption positioning method based on motion posture. Background technique [0002] Today, the application of satellite navigation and positioning has become more and more popular. Satellite navigation and positioning are widely used in our lives, such as the car navigation we are familiar with, ranging from car navigation to wearable embedded products such as watches. Sat nav figure. [0003] For embedded navigation systems, low power consumption design technology has gradually become a problem that many designers pay attention to. The reason is that most of their products are portable and mobile, and these products are often powered by batteries. In fact, over the years, the energy storage density of batteries has not been greatly improved. As for portable devices, especially handheld consumer products, it does not seem to be completely practical to improve...
