摘要
文中主要讲述了基于3轴MEMS陀螺仪,3轴MEMS加速度计空间定位的研究。为了避免环境对定位的影响,文中根据物理原理建立运动模型,结合坐标变换方法,在低功耗无线单片机CC430平台上利用集成了3轴MEMS陀螺仪,3轴MEMS加速度计的芯片MPU60x0设计了一套新的空间定位系统,并采用SimpliciTI协议传输信息。该系统具有高度集成、电路简单、体积小、极低功耗、易扩展、易维护等优点,可以作为基于无线网络定位的辅助手段,改善定位精度,亦可在精度要求相对较低的定位领域应用。
Describe the research of spatial localization which is based on the 3-axis MEMS accelerometer and 3-axis MEMS gyro. In or- der to avoid the influence on positioning accuracy from environment, the motion model is built up based on physical principles. A new spatial localization system is designed combining coordinate transformation method. This system is using the chip MPU60x0 which in- tegrates 3-axis MEMS accelerometer and 3-axis MEMS gyro on low-power wireless microcontroller CC430 platform, and using Simplic- iTI protocol to transmit information. This system has the advantages of high integration, simple circuit, small volume, low power con- sumption, easy to expand and maintain. It can be an additional method for wireless positioning, increasing the accuracy. It also has applied in a environment requires relatively low positioning accuracy.
