Problems solved by technology

[0003] While sensors bring various intelligent functions to portable devices, they also bring battery life problems. All kinds of portable devices are generally powered by batteries, and the battery power is limited, and various sensors need frequent work. For example, ambient light sensors It is necessary to constantly monitor the brightness of the ambient light in order to adjust the brightness of the LCD in time, which consumes the power of portable devices
[0004] figure 1 is a schematic diagram of a portable device control circuit in the prior art, figure 1 The various sensors 3 and the application processor 1 are directly connected through the interface circuit 2, and the various signal processing of the sensor needs to be completed by the application processor. In the portable device, the application processor is in a sleep state most of the time, so as to reduce the power consumption as much as possible. Consumption, and the application processor is frequently woken up from sleep mode, which will consume too much power

Abstract

A control method for sensors comprises: a sensor (4) converts collected analog information to digital information; a low power consumption microcontroller (2) collects the digital information via an interface circuit (3), processes the digital information, and transmits the processed digital information to an application processor (1) via the interface circuit (3); the application processor (1) performs control operation according to the processed digital information. A control device for sensors is also provided.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a sensor control method and device. Background technique [0002] Currently, portable devices are becoming more and more popular in people's daily life. Taking smart phones as an example, it plays an increasingly important role in people's daily life. Smartphones are becoming more and more "smart" as they become popular. For example, smartphones can adjust the LCD brightness of the phone according to the light intensity of the external environment in order to obtain a better user experience; they can also adjust the LCD display content according to the placement of the phone. , adjust to display in landscape or portrait mode; you can judge the direction of the mobile phone according to the position where the mobile phone is placed, so that the mobile phone can have functions such as a compass. The realization of these functions depends on an important component in the mobile p...
