Research on Traffic Control and Handling Capacity of Evacuation Elevator

1.电梯和楼梯疏散时间与单独楼梯疏散时间的比较。研究了无火灾情况下的最小疏散时间。为扩大处理能力，所有电梯均采用穿梭式运行。在分区建筑中，我们将一个建筑垂直划分为若干个截面，截面的数量选择为分区的数量+1。下层人员仅靠楼梯疏散，上层人员靠楼梯和穿梭电梯疏散。在16层建筑中，使用电梯和楼梯的疏散时间比单独使用楼梯的疏散时间约为1/3。可在停电情况下运行的电梯供电和轿厢运行。一旦发生火灾，停电的可能性非常高。利用乘客势能，具有一定储电能力的电梯可以在疏散时运行，因为乘客只能向下而不能向上。我们研究了适当的轿厢操作和可以连续操作电梯的乘客数量。2 .适合穿梭运行，在停电时仅能搭载1/4的乘客。人在出口走楼梯的离散事件模拟。开发了人走楼梯的事件模拟方法。然后，利用电梯事件模拟器实现对建筑物整体疏散的模拟。电梯大厅轮椅使用者的模式识别。如果我们能在电梯大厅用摄像机识别出轮椅人士，就很容易在火灾中引导残疾人。我们开发了一种算法，可以识别坐轮椅的人和正常人之间的区别。

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.
