摘　　要：冰激振动对海洋平台带来了潜在的危害,对其进行实时监测对于海洋油气的安全生产至关重要。振动加速度的值可以反映冰激振动的状态。以海洋平台的振动加速度为监测对象,基于MEMS加速度传感器ADXL202、超低功耗单片机Atmega128L和无线射频CC1000开发了低功耗无线冰激振动监测节点,使用最大最小值法对加速度传感器进行标定,对加速度数据进行后台存储和三维可视化展示。在振动试验平台上进行实际振动监测实验,从频域角度证明了时域实验数据的正确性。对节点的工作及休眠功耗进行测量,节点可以在2 A?h电池下工作两年左右。The ice-induced vibration brings the potential hazards for offshore platform, so its real-time monitoring is vital to production safety of offshore oil and gas. The vibration acceleration can reflect the state of ice-induced vibration. Taking vibration acceleration of offshore platform as the monitoring object, a low-power consumption wireless monitoring node for ice-induced vibration was developed on the basis of MEMS acceleration sensor ADXL202, ultra-low power consumption microcontroller Atmega128L and radio frequency chip CC1000. The maximum-minimum value method is used to calibrate the acceleration sensor, and realize the background storage and 3D visualization display for the acceleration data. The practical vibration monitoring experiments were carried out on vibration test platform, which can verify the correctness of time-domain experiment data in the aspect of frequency domain. The working and sleeping power consumptions were measured. The node can work about two years by using the 2 A·h battery.
