德国Eigenbrodt光学雾探测器ONED250

描述

ONED是一个能见度探测器。它测量微粒的数量 – 雾气中主要是水份限制了能见度。

工作原理

一束窄的红色激光束从正面开**出。 另一开口处透镜后面的探测器对来自一条窄缝与发射机光柱重叠的入射激光敏感。 如果重合的区域有雾粒,光线会被散射回来并被探测器监测到,并产生一个原始的输出信号。敏感区域大约位于传感器前30 cm的位置,体积小于1立方厘米

电子信号

原始信号是模拟信号,它是从重合区域后向散射的光线数量。所以重合区的雾越多,传回的信号也越多。

信号处理:

下面的公式可以推导出能见度: V = konst / VIS

其中, V 是测量的原始信号的水平, konst 是一个校准常数, VIS 是能见度 (单位:米)

测量的限制被设定为3000米。虽然输出是在5000米的能见度才饱和,但3000米以上精度受到限制。为了得到一个目视能见度值,一般取样1分钟,以平均值作为测量结果。

数字输出(可选项)

计算出来的能见度值以ASCII数字串的形式在RS232上显示(1200 baud 8N1),并每分钟传输一次 。Polling action也可以被传递。好的能见度的数字串为”5000”, 如果能见度为1000米则数字串为“1000”。这些数字串可以被带有RS232输入的数据纪录仪接收,当然也可以被安装了终端软件的PC接收。

微处理器还控制着一个无电势半导体开关。当能见度低于设定值时(默认为1000米),则半导体开关被打开。当能见度高于设定值时,半导体被关闭。

微处理器控制的模拟信号输出(可选项)

微处理器还控制直接给出能见度的模拟信号的输出 (VIS = 1 km 结果为 1 V, 当VIS = 500 米时,结果为0.5V,以此类推)。这个输出每分钟更新一次。当用户切换为模拟信号输出的**分钟,仪器显示的值为0.
