背景技术
无尘室或所谓高科技建筑物, 需要大量气流循环来排除污染尘粒, 以 维持工作区的洁净度。 如果以送风机的安排来区分无尘室, 则可分为中央 系统与风扇-滤网机组 (Fan Filter Unit, FFU)系统。 所谓中央系统是以一台大 型风扇来供风, 而 FFU系统则是将小风扇与滤网结合, 不再使用一台大风 扇, 而在无尘室或高科技建筑物的天花板上装设大量的小风扇。
FFU系统具有便利性高、 工期短、 污染控制容易、 整体系统平衡调整 方便等等优点, 国内近年来新建的无尘室几乎全面采用 FFU型式。 然而, FFU系统则因 FFU数量众多, 对现场人员比较不方便, 也因此, 现行的 FFU 系统多为模块化局部控制, 并以整体串联或并联方式连接, 如此, 当 FFU 系统在操作上一部或两部 FFU发生操作上的异常状况, 将造成判断该故障 FFU的困难, 并导致维修的时效性不佳。
一般现有的风扇-滤网机组监测结构具有下列的缺点:
1、 这些风扇-滤网机组采以整体串联或并联方式连接, 其造成风扇-滤 网机组于操作状态监测上的不方便性;
2、 这些风扇-滤网机组采以整体串联或并联方式连接, 其造成风扇-滤 网机组于损坏维修上的时效性差。
由上可知, 上述现有的风扇-滤网机组监测结构, 在实际使用上, 显然 具有不便与缺陷存在, 而有待加以改善。 发明内容 本发明的主要目的在于提供一种风扇 -滤网机组矩阵式定址监测结构, 其将该输入扫描信号依序且循环方式输入至该若干个输入信号列中, 而从 该控制单元的若干个输入端, 读取该输出序列信号的状态并于该控制单元 的若干个输出端, 监测该若干个风扇 -滤网单元的状态。
为了实现上述的目的, 本发明提供一种风扇 -滤网机组矩阵式定址监测 结构, 其包括有:
若干个输入信号列;
若干个输出信号行;
若干个风扇 -滤网单元, 分别连接于该若干个输入信号列与该若干个输 出信号行之间, 用以循环气流与过滤空气;

一监测单元, 连接于该控制单元的若干个输出端, 用以监测该若干个 风扇 -滤网单元的状态;
该输入扫描信号可为一直流电压;
该控制单元可为一可程控器;
该监测单元可为一计算机主机。
