Abstract
AT89C52 single-chip microcomputer is that main control chip design in this paper. As
a "decision-making mechanism", the DC speed reduction motor is use to provide the power
source, direction control and the start and stop of the trolley. An ultrasonic sensor installed
in the center of the front end of the car is used as an input to realize obstacle avoidance of
the car. SR-HC04 is used to detect obstacles, and the distance is calculated by software.
The decision-making body judges whether the trolley follows or avoids obstacles again
according to the distance. The pyroelectric infrared module SR602 installed at the front end
of the car SR-HC04 is placed in the same horizontal direction. It is used to detect the
human body characteristics and realize the human body following through the program
processing. After initialization of each module, SR-HC04 determines whether there is an
obstacle or not, and SR602 searches for a follow-up target to determine the direction of the
trolley without the obstacle. The decision-making mechanism determines the next action of
the trolley according to the obstacle position and the human body position provided by the
two modules. Whether there is an obstacle or whether the obstacle is avoided, or whether
the direction of the target is changed. According to the change of human walking position,
SR602 recognizes the human orientation, controls the motor to follow, avoids all kinds of
obstacles in the process of following by using SR-HC04 ultrasonic module, and realizes
the automatic obstacle avoidance and human body following of the trolley.
Key words:Automatic follow; Obstacle avoidance; Pyroelectric infrared; Ultrasonic;
Human body recognition
