| 摘 要： | 风向传感器采用的格雷码编码方式使得风向传感器故障具有一定的“隐蔽性”,而传统故障检测方法需要拆卸风向传感器破坏了气象观测资料的完整性.基于概率分布从数理统计角度建立了码盘式风向传感器的测量数学模型,并在此基础上提出了基于分布律规则的风向传感器故障检测算法,通过VB/SQL/MATLAB混合编程技术实现了图示化的风向传感器故障检测程序,最后进行了故障检测试验.试验结果表明：提出的基于分布律规则的风向传感器故障检测算法能够在不拆卸风向传感器的情况下准确发现和判断出风向传感器单一或组合式故障类型.

| Abstract: | Since the fault diagnosis of wind direction sensors is extremely concealed owning to its Gray code encoding, traditional fault detection methods need to disassemble the wind direction sensor, which destroys the integrity of meteorological observation data. A measurement model for wind direction sensors based on probability distribution is built, based on which, a fault detection algorithm in terms of distribution law rules is proposed. A graphic wind direction sensor fault detection program is developed though VB/SQL/MATLAB hybrid programming technology. Finally, the fault detection test is carried out, and the results show that the fault detection algorithm can recognize the single or mixed faults exactly without disassembling the wind direction sensor. |
