The Simulation of Lane Based on Magnetic Markers Guidance in Laboratory

It is a high expense that the experiment of the testing vehicle based on magnetic markers carrying on outdoors. The distribution and movement of magnetic markers were simulated by direct-current electromagnet, using single chip microcomputer and power amplifier to control direct-current electromagnet. It cuts down the expense of experiment. This dissertation is focus on mainly the design of lane simulator. In the lane simulator, every 0.5m arranged a direct-current electromagnet. When the speed is 80km/h ,the electrifying time of the direct-current electromagnet is 0.025s . And the electric voltage of the direct-current electromagnet is 24v , and the magnetic field intensity of the direct-current electromagnet is 12000Gs .
