Gray code-based wind direction sensor detection method

The invention provides a wind direction sensor detection method, which comprises the following steps of: measuring Gray codes of six specific direction wind directions and comparing the Gray codes with standard Gray codes according to the particularity of the six groups of Gray codes and the functional characteristics of related photoelectric components. Thus, whether the wind direction sensor breaks down or not can be judged through two times of simple comparison, and the damaged component can be quickly determined under the condition that the fault is found. 本发明提供一种风向传感器的检测方法，通过测取6个特定方位风向的格雷码并与标准格雷码进行比较，依据这6组格雷码的特殊性及相关光电组件的功能特性。这样，经过两次简单对比，即可判断出风向传感器是否发生故障，以及在发现故障的情况下快速确定损坏的元器件。
