Problems solved by technology

[0005] Both of the above two methods can effectively obtain more detailed motion data, but there is also the operation of querying and reading the sensor. No matter how the system process is designed, the power consumption of the system will not be very low, and it is not suitable for batteries. Scenarios where the power supply runs for a long time, and not all scenarios require detailed motion data. For such scenarios, the above two solutions will perform redundant operations and are not suitable

Abstract

The invention discloses a system and a method for measuring target exercise amount with low power consumption. The system includes an MCU and an acceleration sensor, which are connected through a communication port and an interrupt port. The test method includes: the MCU receives the configuration information, configures itself and the acceleration sensor; after the configuration is completed, it actively enters the sleep state and waits to be awakened; the acceleration sensor monitors the movement of the target, and wakes up the MCU to count when the target acceleration reaches the threshold. The MCU judges whether the record should be output, and after the judgment is passed, outputs the recorded data, enters sleep mode, and executes the above process in a loop. The scheme of the present invention counts the motion state reaching the threshold, which can make the MCU quickly enter the sleep state. Since no reading operation is required, the sensor does not need to configure more functions, and functions such as FIFO can be disabled to minimize the system power. consumption. It is very suitable for scenes that only need to roughly grasp the target's motion state and are powered by batteries for a long time.

Description

A system and method for measuring target motion with low power consumption technical field The present invention relates to sensor monitoring field, especially in a kind of motion quantity statistics, low power consumption monitors target motion quantity system and method. Background technique [0002] The traditional method of measuring target motion is: [0003] 1. Quickly cyclically query the state of the acceleration sensor to obtain very detailed motion data. 2, set the acceleration threshold value, generate interruption when exceeding the threshold value, MCU reads the state of sensor immediately, obtains relative Detailed exercise data. [0005] The above two methods can effectively obtain more detailed motion data, but there is also a For query and read operations, no matter how the system is designed, the power consumption of the system will not be very low, and it is not suitable for battery power supply. At the same time, not all scenarios require detailed...
