Title Portable observation and manipulation of the instrument
Abstract In In recent years, the observing system plays an important role in the field of anti-terrorist riot, fishing, field exploration, construction and mapping.Distance measurement and control system does not have the characteristics of portability and long-distance ranging.Therefore designed a small portable concept aiming and manipulation of the instrument, accurate measurement of target distance in the range of 3000m, aware devices pose, to obtain the target image and video information.The paper focuses on the hardware architecture of the system, component selection, system control circuit, system software design,and experimental data processing.ATmega2560-16AU microcontroller as the core, through the mutual cooperation between the range finder, compass, CCD, LCD, buzzer to complete the above work.The results showed that,system performance well,it have high sensitivity, high accuracy, low power consumption, easy to carry, easy to operate, etc. advantages.
