Description

Signal acquisition method, user interface and related device Technical Field The application relates to the field of intelligent wearing, in particular to a signal acquisition method, a user interface and a related device. Background Wearable devices have been increasingly used in the field of monitoring the physical condition of a human body because of their wearability and portability, for example, the wearable devices can measure physiological parameters of blood pressure, blood oxygen, skin temperature, etc. of a human body and monitor sub-health status of a user. At present, because the wearable device is difficult to collect the photoplethysmography (Photoplethysmographic, PPG) signals containing enough effective information and high in signal quality in a short time, more accurate evaluation results of the health state can be given only a few days, and the waiting time of a user is long, so that the use experience of the user is influenced. Disclosure of Invention The application provides a signal acquisition method, a user interface and a related device, which effectively shorten the time spent for evaluating the physical condition of a user. In a first aspect, the embodiment of the application provides a signal acquisition method, which is applied to electronic equipment comprising a pressure sensor module, and the method comprises the steps of identifying whether the pressure sensor module is effectively covered on a detection target of a human body, applying first pressure to the detection target by the electronic equipment if the pressure sensor module is effectively covered on the detection target of the human body, wherein the effective pressure means that the contact pressure between the pressure sensor module and the skin of the human body is greater than or equal to a first threshold value, the greater the pressure applied by the electronic equipment, the closer the pressure sensor module is to the detection target, acquiring a Pressure Pulse Wave (PPW) signal by the pressure sensor module, and evaluating the physical condition of a user by using the acquired PPW signal. By implementing the method provided by the first aspect, the physical condition of the user can be estimated by using the PPW signals, and before the signals are acquired, the pressure sensor module is ensured to be effectively covered on the detection target, so that the pressure sensor module can acquire PPW signals with enough quantity and good signal quality in a short time, the time spent by the electronic equipment for estimating the physical condition of the user is effectively shortened, and the use experience of the user is improved. With reference to the first aspect, in one possible implementation manner, the identifying whether the pressure sensor module is effectively covered on the detection target of the human body specifically includes identifying whether the pressure sensor module is covered on the detection target of the human body based on the PPW signal collected by the pressure sensor module when the contact pressure between the pressure sensor module and the skin of the human body is greater than or equal to a first threshold, where the pressure sensor module is covered on the detection target of the human body specifically includes that a first characteristic of the PPW signal collected by the pressure sensor module meets a preset requirement. Therefore, under the condition that the pressure sensor module is effectively attached to the skin of a human body, the electronic equipment can directly use the PPW signal collected by the pressure sensor module to identify whether the pressure sensor module is covered on a detection target. With reference to the first aspect, in one possible implementation manner, the method for identifying whether the pressure sensor module is effectively covered on the detection target of the human body specifically includes applying a second pressure to enable the contact pressure of the pressure sensor module and the skin of the human body to be greater than or equal to a first threshold value under the condition that the contact pressure of the pressure sensor module and the skin of the human body is smaller than the first threshold value, and identifying whether the pressure sensor module is covered on the detection target of the human body based on the PPW signal collected by the pressure sensor module, wherein the pressure sensor module is covered on the detection target of the human body specifically includes that a first characteristic of the PPW signal collected by the pressure sensor module meets a preset requirement. Therefore, under the condition that the pressure sensor module is not attached to the human skin sufficiently, the electronic equipment can additionally apply certain pressure to the human skin so as to meet the requirement that the pressure sensor module is effectively attached to the human skin, and under the condition that the pressure sensor is at
