具有防雷功能的风信号传送器

雷击是自动气象站采集器被损坏的主要原因之一,特别是经风杆引入雷电损坏采集器的情况极为常见。解决此问题最好的办法是在保证数据接收准确的情况下,从物理连接(包括信号线和电源线)上将风传感器和采集器断开。设计了一款具有防雷功能的气象站风信号光纤传送器,解决了风杆引雷损坏采集器的问题。传送器采用EDA技术设计电路将风信号从传感器经过光纤传送至采集器,并使用防雷电源单独为传感器供电。经测试该传送器在保护了采集器免遭雷击的同时,又保证了数据的准确性,具有很好推广应用价值。

Development of Wind Signal Transmitter with Lightning Protection Function

The collectors of automatic weather stations are damaged mostly by collector faults through wind sensors induced by lightning. The best way to solve this problem is to disconnect the physical connection (signal line and power line) of the wind sensor and collector, on condition that the data is surely collected. An optical fiber wind signal isolator is design for automatic weather stations, which transits wind signals from the wind sensor to collector by means of EDA technology, and in which the wind sensor is powered by the lightning protection power. The tests show that this transmitter can not only protect the collector against lightning, but also guarantee data collecting, and has good promotion and application value.
