摘　　要：阐述了一种基于单片机的扭矩测量系统。系统利用应变式扭矩传感器实现了扭矩及轴向力的监测,并详细介绍了用AD7705芯片采集传感器的输出电压进行模数转换,通过无线收发芯片nRF2401实现数据的无线传送。系统实现了扭矩的实时监测。A kind of torque measurement system was described,in which utilizes strain torque transducer to accomplish the monitaring of torque and axial force. The instruction on the use of AD7705 chip to collect output voltage of transducer in order to execute modular conversion was stated detailed. It accomplished radio transmission of data through radio reception ＆ transmission chip nRF2401 and avoided abrasion and heat emission caused by the use of conductive slip ring and vibration of analog signals. The torque real time monitoring was realized.
