摘　　要：根据单侧计轴传感系统的工作原理,将前端电路分为励磁信号的产生电路和感应电动势的传输电路;分别对各部分电路进行设计和分析;搭建硬件试验平台,对所设计电路功能进行试验验证;验证结果表明,可满足计轴要求。According to the working principle of unilateral axles counting sensor system,the front-end circuit can be divided into two parts,the excitation signal generator circuit and the inductive electromotive force transmission circuit. The functional requirements of the two parts of the circuit are analyzed respectively. A hardware experimental platform is built to verify the circuit＇s functions and the results show that the requirement of axles counting can be satisfied.
