Abstract
This system is designed with the voice of controlling the suspended object precisely, adopting Bus architecture. Each function module is designed dividedly, commended by Master Chip, performing each system function effectually and quickly.
System communicate through message packets meeting with protocol which is the tache connecting system modules as a whole, constructing the master-slave control net made up by several AVR MCU of high perform-price ratio, realizing dispersed control .Self-designed H-type constant-current circuits complete the task of driving the motors excellently. Special Double-LCD achieve a friendly human-machine interactive interface, and monitor the system state directly and Real-time. Skillful motor-double detector seeking-trace mode guarantees very large detect area and tracing precision. All floating-point arithmetic reduce the finite-byte-width effect to smallest.
Base on reliable hardware and effectual software design, this system is qualified with quite high performs.
