Embodiment Construction

[0032] As mentioned in the background technology, the pressure sensing detection in the prior art consumes a lot of power. When there is no pressure sensing signal input, the sampling circuit and processor inside the pressure sensing device are all in the power-on working state to wait for A signal to come anytime. Existing pressure-sensing detection controls power consumption generally by reducing the operating frequency of the microprocessor (MCU) and cooperating with the sleep of the microprocessor (MCU) to implement a low-power strategy, but the effect on power consumption control is limited and cannot meet Higher low power requirements.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all o...

Abstract

The invention discloses a pressure sensing detection device, a pressure sensing detection method and electronic equipment, and the pressure sensing detection method comprises the steps: setting a detection period of a pressure sensing signal, wherein the detection period comprises a sleep stage and a detection stage; activating a sleep stage, and performing sleep timing; activating the detection stage after the duration of the sleep stage reaches a set time, and detecting a pressure sensing signal in the detection stage; and after the pressure sensing signal detection is completed, entering the next detection period. The pressure sensing detection method is low in power consumption.

Description

technical field [0001] The present application relates to the technical field of pressure sensing, in particular to a pressure sensing device, a pressure sensing method and electronic equipment. Background technique [0002] Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments and consumer electronic automatic control fields, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, etc. Industrial industries and various consumer electronics industries such as mobile phones, TWS earphones, wearable devices, and home appliances. [0003] The pressure-sensitive button is an important application of the pressure sensor. The principle of the pressure-sensitive button is to install a pressure sensor on the back of the button panel. The pressure sensor can generate a corresponding anal...
