A miniature car model navigation system

Abstract

The invention relates to a miniature car model navigation system. The miniature car model navigation system includes the following components of: infrared transmitting tubes for emitting infrared light signals, wherein a plurality of infrared transmitting tubes are arranged on road surface; infrared acquisition devices which comprise infrared receiving tubes and are used for acquiring infrared rays transmitted by the infrared transmitting tubes and processing the acquired infrared rays and transmitting the processed infrared rays to a micro controller, wherein at least one infrared receiving tube is arranged on a car model; and the micro controller which is used for performing analysis processing on acquired electric signals, and transmitting the processed electrical signals to a steering engine and a direct current motor; the steering engine of which the rotation angle can be controlled according to first processed electrical signals which are transmitted by the micro controller; and the direct current motor of which the operation can be controlled according to second processed electrical signals which are transmitted by the micro controller such that the operation of the car model can be controlled. According to the miniature car model navigation system of the invention, the plurality of infrared transmitting tubes are arranged at any positions on the road surface, and the car model is provided with the infrared receiving tube; the controller is adopted such that tracking routes can be changed freely; and the tracking routes cannot be seen by naked eyes, and a sense of mystery can be increased.

Description

technical field [0001] The invention belongs to the field of navigation, in particular to a miniature car model navigation system. Background technique [0002] The traditional intelligent infrared sensor car model uses black line detection to emit the light emitted by the infrared emitting tube to the road surface. When the infrared light encounters the white background of the road surface and is reflected, the receiving tube receives the reflected light and compares it with the comparator to output a low voltage. When the infrared light encounters the black line on the road and is absorbed, the receiving tube does not receive the reflected light, and after comparison with the comparator, it outputs a high level and transmits it to the controller. The controller uses the received level signal to Control the steering gear to complete the tracking purpose. [0003] However, the traditional infrared sensor car model tracking route must be black or a dark color with low reflec...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional infrared sensor car model tracking route must be black or a dark color with low reflectivity, and the outside of the black must be white or light color with high reflectivity, so that the naked eye can clearly see the track route, and once the black route Once fixed, only the fixed black route can be driven
