The design of searching and detecting system perched helicopter based on AVR

More and more helicopters undertake the mission of reconnaissance, search and rescue, because they are with the characteristics of fast starting, wide range of searching and so on. Researching these systems play an important role in national security, social stability, modern productions and life. A new system is designed by the usage of AVR in this paper, combining the characteristics of the photoelectric encoder and DC servo control system. The test results show that the system is characteristic with high control precision, stability and the design has achieved the desired objectives.
