摘要
为了实现穿戴式计步器准确计算步伐,本论文设计了一种基于蓝牙芯片CC2541和六轴传感器MPU6050的电子计步器系统。在开发过程中,自主设计了一个简易的电子计步器系统开发板,实现了运动姿态的检测,加速度数据处理和步数在蓝牙设备终端显示。实验结果表明:在走100步时,具有较可靠的稳定性及准确性。该电子计步器可设计为15mm×15mm的小体积仪器,且结构简单、功耗低、抗振动冲击能力强,能够满足较高精度的计步测量要求。
In Order to realize accurate step-counting in wearable equipment, an electronic pedometer system is designed, which is mainly composed of a Bluetooth chip CC2541 and six-axis sensor MPU6050. A simply electronic pedometer system development kit is designed, which has the functions of motion detection, acceleration data processing and Bluetooth device terminal displaying. Experimental results indicate that the system is stability and accuracy when people take 100 steps. This system can be designed as 15mm× 15mm, which is small in size, simple in structure and consumes little power. It can satisfy the system requirements of stepcounting in precision.
