Abstract
With the progress of science and technology, intelligent and automation technology
is more and more popular，High-tech technology is also widely used in intelligent car
river robot toy manufacturing, intelligent robot is more and more diversified. Intelligent
car is a variety of high and new technology integration, integration of mechanical,
computer hardware, software, electronics, artificial intelligence and so on the many kinds
of knowledge, science and technology can be involved in many of today's introduction in
the field of technology.
This design is mainly composed of single-chip microcomputer control system
module, motor drive module, the infrared obstacle avoidance module, voice control
module, system with STC89C52RC single-chip microcomputer as the core, through the
obstacle avoidance module and voice control module receives information to control the
motor running. System by 7 1.5 V dry cell by step-down circuit down into a stable dc 5 V
for single chip microcomputer and engine power. This paper introduces the principle of
infrared obstacle avoidance, the introduction of overall system design and related
software. Software part adopts the modular design thinking, the process includes the main
program, motor driver, signal detection procedures, through the car runs the operation of
the detected information call to turn left, go straight, or stop function to control the car.
Test results show that the various functions of the basic normal, in addition to the engine
speed does not match to achieve all the requirements of the design.
Key words: obstacle avoidance SCM STC89C52RC cars
