建筑日照测量仪研制

Development of Sunshine Measurement Instrument on Buildings

介绍了建筑日照测量仪的研制原理、设计方案及使用方法。仪器通过显示器观察白天太阳周日圈上遮挡物,由编码器测量每个遮挡物所遮挡的日照时间。由于仪器采用机械装置动态模拟了日地方位角变化关系,从而保证了显示器摄像头始终沿太阳周日圈扫描(仪器专利名称:一种建筑日照测量装置,专利号:201120007301.9)。对比检验表明,当采用1000脉冲编码器,通过4倍频,其分辩率为21.6s,误差在1.5min以内。仪器结构紧凑,设计小巧,使用方便,一次常规测量只需几分钟,大大降低了测量成本,达到了现场实测、直观显示的技术要求。该仪器可用于日照纠纷仲裁,建筑日照以及气象、雷达探测环境遮挡角测量。

The principles,design schemes,and usages of architectural sunshine measurement instrument are described.Through observing the occluders on the diurnal circle of the sun in the daytime by the instrument display,the time duration obscured by each occluder is measured by the encoder.As the mechanical devices in the instrument are used to simulate the dynamic relationship between changes in sun-earth azimuth,the monitor camera is ensured always scanning along the diurnal circle of the sun(instrument patent No: 201120007301.9).Comparison test shows that when using the 1000 pulse encoder,with 4-fold frequency and a resolution of 21.6 s,the measurement error is less than 1.5 min.The instrument is compact,portable,and easy to use,and the measurement cost is greatly reduced.This instrument can be used in various sunshine measurements,such as the sunshine duration measuring related to sunshine dispute arbitration,architectural sunshine,and ambient occlusion angle for meteorological and radar stations.
