Most of Chinese cities have experienced a great wave of large-scale neighbourhood renewal in recent years. However, only a few research works have been done in giving assessment after the completion of renewal project...Most of Chinese cities have experienced a great wave of large-scale neighbourhood renewal in recent years. However, only a few research works have been done in giving assessment after the completion of renewal projects. Aimed at such a circumstance, this paper, by referencing the experience of European countries, establishes a multi-dimensional evaluation framework to analyze the primary data drawn from recent household surveys of Shichahai and Jinyuchi neighbourhoods in Beijing, and puts forward some suggestions based on the conclusions drawn from the surveys.展开更多
针对传统办公室LED照明系统光照适配性差、能耗偏高、缺乏动态调节能力等问题,提出一种基于多传感器融合的自适应调光系统。该系统通过集成光照、人体存在、人体姿态及温湿度传感器,采用加权模糊融合算法实现多源传感数据的特征级融合,...针对传统办公室LED照明系统光照适配性差、能耗偏高、缺乏动态调节能力等问题,提出一种基于多传感器融合的自适应调光系统。该系统通过集成光照、人体存在、人体姿态及温湿度传感器,采用加权模糊融合算法实现多源传感数据的特征级融合,结合模糊比例-积分-微分(proportion integral differential,PID)控制策略完成LED照明的精准动态调节。试验结果表明,该系统可根据办公室人员状态、环境光变化及温湿度条件自适应调整照明参数,相比传统常亮照明系统节能率更高,为办公室提供舒适、节能、智能的照明环境。展开更多
