1, background

This survey is based on the four elevators of the basic teaching building of Shijiazhuang Railway University. The basic teaching building of Shijiazhuang Railway University consists of 2 to 19 floors and 21 floors.

The basic situation is as follows:

(1) A total of four elevators, two single-storey docking, two two-tier docking; Due to the 1~7 level of classroom courses, not stop, each elevator about 15 people, load 1150kg.

(2) Elevator speed: Go upstairs average speed about 2.5s/layer, downstairs average speed about 2.9s/layer, open and close time 3s, passengers enter the elevator time 2s to 10s range (determined by the number of passengers).

(3) The peak number is about 100 people. Take the elevator to the 8 floor and then take the stairs into the 6, 7 floor class students, so

All data are subject to actual error.

2, question

(1) Congestion during class hours;

(2) The actual human factors are chaotic, do not rule out the phenomenon of the floor random press stop;

(3) Elevator failure, elevator suspension for maintenance.

3, Solution

(1) Single-layer docking system, some floors do not stop ( -2~7 floor)

(2) Set up an infrared sensor at the door of the elevator, the elevator will stop when both the person and the button are pressed. For those who only press but no one, the elevator does not stop. (In case of entering the elevator)

(3) Elevator failure, start the standby scheduling scheme. Allow other elevators to operate in a restricted mode.

4, elevator scheduling can realize the function

(1) User input floor data (by floor button)

(2) Overload elevator fault warning error

(3) Show elevator status, store elevator information

5, summary

For the elevator dispatch, my partner Guo Ting and I observed the use of elevators before class. The specific situation is as above.

We also have according to the circumstances of the elevator may appear if the students are late in class to stop the elevator a few minutes earlier to make students consciously advance to the classroom or in these minutes to open the 1~7 floor elevator use to avoid students late; elevator failure situation, other elevators need to change the scheduling plan (the number of elevators used more , if the double-deck elevator failure, whether to make a single-deck elevator to double-deck docking) and so on. However, these assumptions do not have practical value in practice. So there is no specific proposal.

We will make later improvements based on the scheduling scheme we can implement.
