Apparatus and method of applying magnetic pattern to lanes with magnetic paint
Disclosed herein are an apparatus and method for applying a magnetic pattern to lanes with magnetic paint. The apparatus includes an electromagnet for generating a write magnetic field toward the ground by being installed in a moving object, a current supplier for providing the current required to generate the write magnetic field, a portable power generator for supplying power required in order for the current supplier to generate the current, and a cooler for dissipating heat generated from at least one of the electromagnet and the current supplier.
1. An apparatus for applying a magnetic pattern to lanes with magnetic paint, comprising:
an electromagnet for generating a write magnetic field toward a ground by being installed in a moving object;
a current supplier for providing a current required for generating the write magnetic field;
a portable power generator for supplying a power required in order for the current supplier to generate the current; and
a cooler for dissipating heat generated from at least one of the electromagnet, the current supplier, and the portable power generator,
wherein the current supplier and the portable power generator are installed in an auxiliary moving object that is separate from the moving object in which the electromagnet is installed.
2. The apparatus of claim 1 , wherein
magnetic particles included in a base material of the magnetic paint applied to the ground are ferromagnetic particles having a coercive force greater than 100 Oersted (Oe) and equal to or less than 1000 Oe,
wherein the electromagnet is located at a distance from the ground, and the distance is greater than 0 mm and equal to or less than 300 mm, and
wherein the current supplier supplies a current greater than 0 ampere and equal to or less than 100 amperes.
3. The apparatus of claim 2 , wherein the electromagnet generates the write magnetic field having a strength greater than the coercive force of the magnetic particles.
