Embodiment Construction
[0042] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0043] In this embodiment, the electromagnetic induction-based path tracking sensor designed in the present invention is applied to the tracking system of the smart car, and the tracking system is such as figure 1 Shown. The tracking path uses enameled wire as a guide wire, and an alternating current is applied through a signal generating device at both ends, and an alternating magnetic field is excited around the guide wire. The surrounding magnetic field signals such as figure 2 Shown. The sensor is fixed at a certain distance in front of the car through a forward-looking bracket made of carbon rods, the MCU processor is fixed on the car, and the steering gear and motor are controlled by the MCU processor to control the movement of the car, and the sensor is used to complete the tracking function of the smart car . Since the sensor is fixed...
