for this survey of the elevator, we need to understand how the elevator operates, the speed, the time between the switch door, and the maximum weight that the elevator can bear.
(1) Purpose:
Design and implement an elevator scheduling algorithm. Training skills: Requirements analysis, high-level design, design documentation, algorithmic design.
(2) Demand analysis:
In the basic teaching building of Shijiazhuang Railway University, there are four elevators in each floor, a total of 18 floors.
Passenger weight: Average 70 kg, maximum 120 kg, min. 45 kg.
According to the survey of the elevator, the daily flow before class is larger than the time of the switch door is about 3s.
In the school teachers dedicated elevator each floor stop, ordinary elevators in the 8 to 18 stop, two elevators in double-stop, two elevators in the odd layer stop.
Maximum weight: 1150kg
Number of passengers: 15 persons
Opening and Closing time: approx. 3s
