Arm Microcontroller Stacker Control Of Key Technologies

Nowadays, the automatic warehouse has been applied more widely. However, the management of the automatic warehouse is based on the effective control of the Stacking Crane. Traditionally PLC or single chip processor acts as the controller of the Stacking Crane. PLC controller is used widely in controlling the Stacking Crane as its steady performance. Nevertheless, the defect of the PLC controller is the high price. With the continuous development of the Embedded System and the Micro Processor, more and more control systems tend to use the new Micro Processor.Under such technical application background, a method was presented to use ARM processor to realize the control of the Stacking Crane. This paper analyzed the function of the Stacking Crane control system firstly and proposed the module structure of the control system. Then the detect circuit of travel switch, motor driver circuit and the protect circuit of terminal were discussed deeply. Based on the module partition of hardware, this paper designed programs of IIC Bus driver, PWM timer driver, keyboard driver and motor driver. Also, the modification of important program to transplantμC/OS-II embedded operating system was discussed. On the base of hardware and software, the thesis analyzed the step of automatic running, designed the data structure, and constructed key function to execute the step.This paper analyzed and summarized ARM Processor and the Stacking Crane. The function of running the Stacking Crane to carry or get goods controlled manually, automatically or by PC was designed and realized finally based on the method mentioned in this paper.
