摘　　要：介绍了ADIS16354器件(陀螺仪和加速度计集成传感器)的基本功能;利用TMS320F2812 DSP搭建了一个硬件平台并通过SPI接口完成对ADIS16354的控制、数据采集和状态查询;结合捷联惯性导航系统姿态解算算法及DSP快速解算的特点实现了载体的俯仰角和倾斜角的测量;编写上位机程序实现对ADIS16354的配置和解算结果的实时显示。在无磁转台上进行了静态和动态条件下的测试,结果表明:该姿态角传感器具有较高的角度稳定度(陀螺漂移率小于0.02°/s)和准确度,抗磁干扰能力强,可广泛用于在工业自动化、导航定位、航空航天等场合。A complete triple axis gyroscope and triple axis accelerometer-ADIS16354 chip were introduced and a hardware platform was constructed using TMS320F2812 CPU.The CPU controls the ADIS16354 chip,and retrieves the acceleration,angles rate and status in real-time through SPI interface.According to attitude algorithm and DSP excellent computing ability,the outputs of ADIS16354 chip is applicable for computing pitch angle and roll angle of carrier.The result of static and dynamic testing shows that this system has high stability and high accuracy,and it is not affected by magnetic field.It can be widely used in many areas,such as industrial automation,navigation,aeronautics and astronautics.
