项目摘要

After many research papers of evaluation methods and measuring instruments for visual environment have been gathered and investigated. several factors for integrated evaluation system of a visual environment have been selected; i.e. horizontal illuminace, vertical illuminance, scalar illuminance, vector illuminance, mean cylindrical illuminance, vector/ scalar ratio etc. Generally, those factors have been measured individually for the lack of suitable integrated measuring instrument and the measured data have not been used all together but some combinations. Therefore the authors considered to be essential to develope an integrated measuring instruments for the above mentioned factors and also an integrated evaluation system of a visual environment. A portable six-photo-elements illuminance meter has been designed and trially made and proved to be excellent for the usual measurement of all most of above mentioned factors in the same instant. All measuring data are automaticlally stored in the hand-held-computer assembled to the meter. Several factors such as vector/scalar ratio can be easily calculated by the assembled computer. Using the portable six-photo-elements illuminance meter, the authors carried out contineous in long duratuion measuremnts or only once measuremnts of several visual environment factors at a typical office room and all the data were stored in the mini-floppy discs. The results of the measurements have been investigated and the visual environment of the office room has been evaluated. The fruits of this research work, especially, the portable six-photo-elements illuminance meter convince the authors of usefulness for the practical evaluation of visual environment.

经过大量的研究，对视觉环境评价方法和测量工具进行了收集和调研。视觉环境综合评价系统选择了水平照度、垂直照度、标量照度、矢量照度、平均柱面照度、矢量/标量比等几个因素，由于缺乏合适的综合测量仪器，这些因素通常是单独测量的，测量的数据不是全部使用，而是一些组合使用。因此，作者认为有必要开发一套针对上述因素的综合测量仪器，以及一个综合的视觉环境评价系统。设计并试制了一台便携式六像元照度计，该仪器可同时测量上述大部分因素。所有测量数据都自动存储在组装到仪表上的手持计算机中。几个因素，如矢量/标量比，可以很容易地通过组装的计算机计算。利用便携式六像素光照度计，对一个典型办公场所的几个视觉环境因素进行了长时间连续或一次性连续测量，所有数据均存储在小型软盘中。对测量结果进行了调查，并对办公室的视觉环境进行了评价。本研究的成果，特别是便携式六像素光照度计，使作者相信这对实际的视觉环境评价是有用的。
