Research on Traffic Control and Handling Capacity of Evacuation Elevator

1.比较了电梯加楼梯疏散与单纯楼梯疏散的疏散时间，研究了无火灾情况下的最小疏散时间。为了增加处理能力，所有电梯都作为穿梭机运行。在建筑分区中，我们将建筑物垂直地划分为若干个分区，分区数取为分区数+1。最低层的人员仅通过楼梯疏散，较高层的人员通过楼梯和穿梭电梯疏散。16层楼的情况下，通过电梯和楼梯的疏散时间比单独通过楼梯的疏散时间约为1/3。2.电梯供电和轿厢运行，可以在停电的情况下运行，一旦发生火灾，停电的可能性很高。利用乘客的势能，带有一定功率存储的电梯可以在疏散中运行，因为乘客只向下而不向上。我们研究了轿厢的正常运行和可以连续运行电梯的乘客数量。3.疏散通道中人走楼梯的离散事件仿真研究了人走楼梯的离散事件仿真方法。4.电梯候梯室轮椅人的模式识别如果能用摄像机识别出电梯候梯室的轮椅人，就能方便地对火灾中的残疾人进行引导。我们开发了一种算法，可以识别轮椅人和正常人之间的差异。

1.Comparison of evacuation time between evacuation by elevators and stairs and that by stairs alone.The minimum evacuation time without fire is studied. To enlarge handling capacity, all elevators operate as shuttle. In zoning building, we divide a building into some sections vertically, and the number of section is chosen as the number of zones +1. The people in lowest section evacuate by stairs alone and the people in higher section evacuate by stairs and shuttle elevators. The evacuation time by elevator and stairs is about 1/3 compared with that by stairs alone in case of 16 floors building.2.Elevator power supply and car operation that can operate in blackout.In case of fire, the possibility of power failure is very high. Using the passengers potential energy, elevators with some power storage can operate in evacuation, because the passengers go downward only not upward. We studied the proper car operation and the number of passengers that can operate elevators continuously. The shuttle operation is suited and the car can operate with only 1/4 passengers of car capacity in blackout.3.Discrete event simulation of people walking stairs in egress.We have developed the event simulation method of people walking stairs. Then, the total evacuation simulation of buildings becomes possible with the elevator event simulator.4.Pattern recognition of wheelchair people at elevator lobby.If we can recognize wheelchair people at elevator lobby with video-camera, it is easy to guide handicapped people in fire. We have developed an algorithm which can recognize the difference between wheelchair people and normal people.
