[0040] The working principle of this device is as follows: During blood pressure measurement, the pressure sensor is strapped to the user's arm with a strap. The power switch is turned on, and the user issues a voice command to "start measurement." The voice pickup module collects the voice command and sends it to the audio amplification module for amplification before outputting it to the audio recognition module. The audio recognition module performs voice recognition to obtain a voice control signal. Based on the recognized voice control signal, the control module calls the blood pressure measurement control logic stored in the storage module and issues a control signal. The inflation drive module drives the inflation pump at regular intervals according to the control signal from the control module to perform inflation operations. The deflation drive module drives the deflation valve at regular intervals according to the control signal from the control module to perform deflation operations. During inflation and deflation, the pressure sensor continuously monitors the user's blood pressure data until the blood pressure measurement is complete.

[0041] Once the blood pressure measurement is complete, the speaker announces the result, and the display screen shows the result.

[0042] In summary, the blood pressure measurement device described in this embodiment automatically measures blood pressure after receiving voice commands from the user.
