Abstract
The intelligent control system of electric tracking trolley that uses infrared sensor as sensitive component and AT89S51 microcontroller as control core is designed in this paper. The design employees infrared receiver and transmitter to detect the runway information and AT89S51 to control the electric trolley tracking and auto parking. The system has the characters of simple circuit structure, high reliability, high intelligence and low power consumption. The paper describes the system's hardware and software design flow in detail. The result shows that the smart trolley in the absence of human intervention could independently run and stably track the target.
