The Software Design of Wired remote machine car
Abstract: With the development of society, remote machine car is used more and more widely in our life. Remote machine car is a programmable and multi-function operation which used to transport materials, spare parts, and tools. Or it is programmable system which can be changed for the special moves or the implementation of different tasks.
The system consists of hardware and software design. Hardware circuits include a wireless remote control module, STC89C52 MCU part of 7279 keyboard parts, liquid crystal display part, 8253 part of the output PWM wave, dual-motor drive circuit components. The DC motor drive module is designed by DC motor with the programmable timer / counter , L298N and the driver gate 74 LS07. Software control by programming in the form of 8253 to PWM wave output volume of its control. The main control program, compilation language, controls five operational states of the car including forward , reverse, turn left, turn right and stop. The system simple and good performance machinery velocity modulation prices are high, really to direct the electrical machinery velocity modulation control system of high-precision.
Vehicle based on machine technology, not only for China's space technology and fierce competition in the advantageous position of resources is crucial, but also includes navigation control, including related technology has a huge role in promoting.
