摘要
介绍了JC型传感器的转速与扭矩测量的原理。JC型传感器发出近似正弦信号,由转换电路转换为方波信号;运用8031单片机构成检测电路,通过检测方波信号的频率测得转速,通过检测方波信号的脉冲宽度测得扭矩。
Rotary speed and torque measuring principle based on JC sensors is introduced in this paper. The approximate sine signals output by JC sensors are transformed into quadrate wave signals by the transform circuit. The checking circuit consists of a 8031 sin- glechip, it determines the rotary speed by measuring the frequency of the quadrate wave signals, and determines torque by measuring their pulse width.
