ABSTRACT

Aiming at the requirements of wearable devices such as miniaturization, low power consumption and high precision, this paper analyzes the characteristics of pilots' flying mission in the air, and designs the pilot's multi-physiological parameter acquisition system. The system mainly consists of ADS1292R, LMT70, LIS2DW12 and other high-precision data sampling devices, STM32L476 low-power microprocessor and DA14580 low-power Bluetooth transmission module. According to the characteristics of the pilot, the power consumption of the system is managed, so that the overall power consumption of the system is smaller, and the data of the three days before and after the task can be collected and recorded at one time and then transmitted. The design of pilot physiological data acquisition system can effectively extract the physiological parameters of pilots, such as ECG, respiration, body temperature and overload. It is of great significance to guide pilots' health management and flight training.
