Research on Traffic Control and Handling Capacity of Evacuation Elevator

1.比较了电梯、楼梯疏散与单独楼梯疏散的疏散时间，研究了无火灾时的最小疏散时间。为了扩大处理能力，所有电梯都以班车的形式运行。在分区建筑中，我们将建筑物垂直划分为若干区段，区段数取为分区数+1。最低区段的人员仅通过楼梯疏散，较高区段的人员通过楼梯和往返电梯疏散。在16层楼的情况下，电梯和楼梯的疏散时间比单独使用楼梯的时间约为1/3。2.电梯供电和轿厢运行可以在停电情况下运行，一旦发生火灾，停电的可能性很高。由于乘客只能往下走而不能往上走，利用乘客的势能，带有一定储能的电梯可以在疏散中运行。我们研究了适当的车厢操作和可以连续操作电梯的乘客数量。适合班车运行，仅需1/4车厢载客量即可在停电状态下运行。3.人员在出口走楼梯的离散事件模拟。4.电梯大堂轮椅人的模式识别。如果能用摄像机识别电梯大堂的轮椅人，就可以很容易地引导残疾人进入火灾。我们开发了一种算法，可以识别轮椅人和普通人的区别。

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.
