Problems solved by technology

[0005] The application of the pressure sensor can realize the function of the physical button, which greatly improves the user experience, but it also brings many problems that need to be solved, such as the power consumption of the pressure sensor when it replaces the physical button for volume adjustment. Problem: Since the pressure sensor always needs to be regularly scanned and calibrated to remove normal temperature drift during the working process, the pressure sensor needs constant power supply even when it is turned off, and the power consumption is high; at the same time, the higher the scanning frequency of the pressure sensor, the higher the response speed It is also faster, but the power consumption is greater, which makes power consumption and reaction speed a contradiction; in summary, constant power supply and constant high-frequency scanning will make the power consumption of the pressure sensor higher, and it is difficult to meet the terminal power consumption requirements

Embodiment 1

[0077] This embodiment provides a low power consumption management method for a pressure sensor, the core idea of ​​which is: when the terminal host enters sleep or shutdown mode, the working frequency of the pressure sensor is appropriately reduced, which can not only ensure the working requirements, but also ensure the power consumption of the pressure sensor at a certain time. Reduce power consumption to a certain extent.

[0078] Normally, the host has four states, which are: normal working state, power-on state, shutdown state, and sleep state; when the host is in different states, other functional units may also be in different states accordingly, so this embodiment The four states defined in the pressure sensor are: NORMAL state, STARTUP state, STANDBY state, and POWEROFF state, which correspond to the four states of the host.

[0079] When the host is in the off state and dormant state, the pressure sensor still needs to continue to scan and calibrate to remove the nor...

Embodiment 2

[0095] In the first embodiment, to correspond to the four states of the host, the pressure sensor also defines four states: the first high-speed scan state, the second high-speed scan state, the first low-speed scan state, and the second low-speed scan state. These four states have different scanning frequencies according to different work requirements, and can be set as the first high-speed scanning state > the second high-speed scanning state > the first low-speed scanning state > the second low-speed scanning state.

[0096] There are four states of a pressure sensor in the above embodiment, and the transformation and adjustment are a bit cumbersome. Therefore, this second embodiment will simplify this: the state of the pressure sensor is simplified into two types, one is the high-speed scanning state, and the other is the state of high-speed scanning. Low-speed scanning state.

[0097] When the host enters the startup state or enters the normal working state, the pressure ...

Embodiment 3

[0099] like Figure 8 As mentioned above, the third embodiment provides a mobile terminal 800, the mobile terminal 800 has a touch screen and a host, and further includes:

[0100] The pressure sensor 810 is used to perceive the pressure value at the specified position and to identify and output it; in this embodiment, the function of the pressure sensor 810 is to sense the pressure value at the position of the volume adjustment virtual key on the touch screen, and to identify the relevant volume adjustment accordingly. Touch operation type, including volume up operation and volume down operation.

[0101] The state parameter definition module 820 is used to define various types of working states of the pressure sensor 810 and scanning frequency parameter values ​​in various working states, as well as the mapping relationship between the working states of the pressure sensor 810 and the host. The working states of the pressure sensor 810 can be defined as four types, correspo...

Abstract

The invention discloses a low-power-consumption management method for a pressure sensor, and a mobile terminal. The low-power-consumption management method comprises the step of controlling a pressure sensor to reduce the scanning frequency when a host of a mobile terminal enters a shutdown state or a state of dormancy. The invention brings forward a scheme for reducing power consumption when a pressure sensor is used for volume buttons. Working modules of a pressure sensor are switched according to different host states. Therefore, the method meets a calibration requirement and also a requirement of power consumption reduction, and is suitable for various mobile terminals. The user experience is greatly improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a low power consumption management method of a pressure sensor and a mobile terminal. Background technique [0002] It is a major trend for pressure sensors to enter the design and layout of mobile phones. They can directly report the three-dimensional data of coordinate values ​​and pressure values. Based on this three-dimensional data, the current type of pressing operation can be identified. Therefore, pressure sensors can replace physical buttons, such as used to realize volume. Adjustment function. [0003] like image 3 As shown in , there is a pressure sensor under the volume adjustment bar on the terminal screen. When the user adjusts the volume by pressing the operation, the pressure sensor identifies the operation type according to the pressure difference detected at the "+" and "-" positions. When the pressure value detected at the "+" position is greater than ...
