Demand analysis of elevator dispatching
Pair of people: Ranghujie, Liu Bojian
I. Background of the project
Shijiazhuang Railway University basic teaching building has four elevators, but the basic teaching building has 18 layers, every day there are students busy to class, every day there are groups of students in line waiting for elevators, and sometimes it is better to climb directly to the fast
Ii. purpose of the project
for students to relieve the pressure of the peak elevator, improve the utilization of elevators.
III. Project Survey
(1) A total of 18 floors, 4 elevators, each with a limit of 15 people, weight limit 1150kg.
(2) 1, elevator 2nd stops only 1 floors and 8-18 double-storey buildings, 3, 4th elevators only one floor and 8-18 single floor.
(3) Peak: 7:30--8:00,11:50--12:20,13:30--14:00,17:50--18:10, 18:30--19:00,20:40--21:10 upstairs number: 10~15 people, downstairs number: 10~15 people. and 7:30--8:00 and 13:30--14:00 and 18:30--19:00 students are mostly upstairs, 11:50--12:20 and 17:50--18:20 and 20:40--21:10 are mostly downstairs.
(4) During the class, there was basically no elevator.
Iv. Project Analysis
after the data and the actual situation analysis, the theory with practice, the four elevators, should be in the least time to transport the most students. Through the investigation, the main should be on the eight floor when the teacher elevator to students open, to alleviate the situation of students with elevators, the program should be able to feedback information in a timely manner to the elevator, to deal with different time periods of the elevator call problem.
v. Problems in existence
(1) elevator safety, should always check whether the elevator failure, so as not to avoid unnecessary trouble;
(2) elevator use, according to the student's class time to arrange the elevator reasonable call, and should increase the lift load capacity
(3) elevator maintenance, in the elevator problems, can in the shortest possible time to solve the problem, do not affect too much normal use of time
Vi. Summary of the project
through this stage of actual research, to respond to demand analysis, solve practical problems, so that we have more progress, more understanding of the software requirements and analysis process.
