摘　　要：设计一种基于nRF51822芯片的汽车无线姿态测量系统;该系统以新型无线射频芯片nRF51822作为处理单元和无线发射模块,结合MPU6050传感器设计而成,两者之间通过I2C接口通信。nRF51822通过无线模块与上位机通信,上位机采用LabVIEW平台对汽车原始数据和姿态角数据进行实时显示、存储,实现一种高性能、低成本、低功耗的无线汽车姿态测量系统。实验测试表明:无线通信姿态测量系统实时性好、精度高,能够满足一般汽车姿态测量要求。A radio attitude measurement system based on nRFSI822 for car is designed. The system consists of MPU6050 and a novel nRFS1822 which acts as a processing unit and a wireless transmitter module, nRF51822 and MPU6050 can communicate with each other through I2C interface. PC uses LabVIEW as a development platform to display the original data and attitude angle of the car via communicating with radio module of nRFS1822 in real- time. The system achieves high performance, low-cost and low-power consumption. Experiments can prove the ad- vantage of the designed system which can meet the general requirement of automotive attitude measurement.
