基于单片机的分布式无线转速测试系统

摘要

Based on single-chip microcomputer control technology, a wireless distributed revolution measurement system was developedby using hall sensors. The system makes it possible to monitor the rotate speeds on differ-ent axles in real time. The practical test results indicate the system has a good ability of anti-disturbance and keeps a high precision.%基于单片机技术，设计了一种分布式无线转速测试系统，可用于田间作业拖拉机的多轮转速实时监测。系统利用霍尔传感器将转速信号转换为电信号，数据通过无线发射模块发送至单片机系统。实验结果表明本系统抗干扰能力较强，精度较高。
