Title the disign of The heading angle binding instrument based on MCU
Abstract
This text introduces the design and realization of portable aircraft course angle binding instrument based on MCU51 and MAX197.MAX197 collects the angle signals, and deliver the angle signals to MCU AT89C51,MCU accomplish the intelligent control and displays the real-time angle on the LED at the same time. The apparatus designed have advantages of small size, easy operation, character display and alarming as well as convenient portability and field use.
The entire circuit is made up by the functional circuit of signal acquisition and processing、MCU control、liquid crystal display、buzzer control and so on.MAX197 can directly convert the angle into serial digital signals for microprocessor to process,the circuit of the system is a simple interface circuit、a small number of external components、a short period of exchange time、powerful function、high reliability and Cost-effective。
