【Abstract】 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.更多还原
