ABSTRACT
With the growing of Factory Automation, Computer Integrated Manufacture System and extensive application of Flexible Manufacture System、Automatic Warehouse, the application field and technical level of AGV which contact and adjust the discrete logistics system, make the mission continuous, has greatly enlarged and improved.
AGV is the unmanned driver automatic guided vehicle which has its untouched guided equipment, its control center is the microcontroller and storage battery is driving power, its basic function of automatic action is guided driving, recognizing the address to stop precisely and remove the load. As the valid measure of contemporary logistics processing automation and the key equipment of flexible manufacture system, the AGV has already got more and more extensive application, so that the research on AGV has very important theory meaning and realistic meaning.
The dissertation introduced the applications and developments of AGV at home and abroad. Combining with the request of this graduation project topic, we designed a whole infrared rays guided vehicle.
The main work in this dissertation was arranged as follows:
1. The constitution of AGV system, the path guided means and their principles were discussed. According to the requests of the topic, infrared rays guided method was used in the AGV system.
2. The design of AGV mechanical structure was introduced, in terms of driving manner and working requests, the type of the chassis, electrical motor and storage battery etc. was chosen and designed.
3. According to the control and the craftwork requests of the AGVS, the total frame structure of control system was designed. About hardware, the right sensor, MCU and motor controller had been chosen, the sensing circuits and MCU controlling hard circuits was designed, about software, to achieve many system
4. functions, and to realize serial communication between the MCU and motor controller, blocking programming method was employed.
Key words: AGV; MCU; Drive and control circuit; Running string
