AI Technical Summary
Technical Problem
Wireless sensors have short battery life in harsh environments, and existing timing sampling methods require frequent intervention from the main controller, resulting in high power consumption and potential loss of vibration events.
Method used
The design incorporates multiple operating modes, including normal mode, silent mode, countdown mode, periodic mode, trigger mode, and periodic + trigger mode. Combined with the first and second accelerometer sensors, it enables low-power data acquisition and storage.
Benefits of technology
It enables low-power data acquisition in different application scenarios, avoiding excessive battery power consumption and missed detection of vibration events, and is suitable for short-term continuous testing and long-term periodic monitoring.

Abstract
本发明公开了一种无线传感器工作方法，包括步骤S1：休眠状态下，MCU和无线传输模块均处于低功耗休眠状态，默认无线传感器工作于每休眠T0时间后保持T1时间唤醒的休眠周期，并且在T1时间内如果收到无线网关的唤醒信号，则进入步骤S2的待机状态，否则继续进入休眠并且重复步骤S1。本发明公开的一种无线传感器工作方法，其具备多种工作模式、功能更完善、可以兼顾更多的应用场景；具备包括正常模式、静默模式、倒计时模式、周期模式、触发模式、周期+触发模式的多种工作模式，可以满足短时间持续测试、长时间周期监测、阈值触发采集等多种方式。
