自动气象站风信号转换器的准确度分析

Accuracy analysis of the automatic meteorological station wind converter

为了隔离雷电的信号对自动气象站风塔传输数据的影响,自动气象站使用风信号转换器,通过光纤进行风信号数据的传输。为了评估自动气象站风信号转换器对风信号观测数据传输的影响,分别对其进行风向风速准确度的实验室检测和外场比对实验进行验证。实验结果表明：在实验室检测中自动站风信号转换器能够准确、可靠地传送风速传感器和风向传感器的输出信号。在外场实验对比中,风向和风速小时数据和分钟数据存在少许偏差,但运行趋势一致性较好。通过实验结果可以得出结论,自动气象站风信号转换器对风速数据的传输无明显影响。

According to avoid the automatic meteorological station＇s wind data reflected by lightning signal Automatic meteorological station use wind converter transmitting the data.In order to evaluate automatic station wind signal converter for the influence of the wind data transmission.Test the accuracy of the wind speed and the wind direction in outside and in the laboratory.The test results in laboratory shows that the automatic meteorological station wind converter could be accurate and reliable in transmission of wind speed sensor and the wind sensor output signal.The result of outside test had little error of hour＇s data and minute＇s data,but the consistency is good.Analyzing the outcomes of the experiments,we can get the result that automatic station wind signal converter has no effect to the wind data transmission.
