A: Preface

1. Background: Stone Iron big Elevator Dispatch. According to domestic and international statistics, passengers in the elevator in the car for more than 1 minutes, that is, causing discomfort. Therefore, the manufacturers continue to develop high-speed elevators and scheduling technology. The purpose of this paper is to discuss the transportation of elevator during peak period.

2. Objective: Increase unit time traffic and reduce energy consumption.

3. Current situation: Stone iron large basic teaching building elevator: 4 public Elevators (two 20-storey 20-station, two 18-layer 18-station, complete set of 22 Group control), 1 teachers elevator 20 Floor 20 station, are giants Kone gps53k, load 1150kg, speed 1.60m/s.

Second: Preliminary investigation

On-site investigation, Peak period: weekdays, 7:40-8:05,9:50-10:10,11:57-12:12,13:45-14:00,15:50-16:10,17:55-18:15

Peak passenger status (average per ladder): upstairs: 12~15, Downstairs: 12~13 people

Leisure passenger status (average per ladder): up and down

Open/close time: 3s

Number	Specifications	Stop Layer	Actual speed	Flat-layer Time	Average Transit time
A1	20 Floor 20 Stations	-2,-1,1,9,11,13,15,17	About 0.8M/S	8.7s	37.2s
A2	18 Floor 18 Stations	1,9,11,13,15,17	About 0.8M/S	8.7s	36.5s
B1	20 Floor 20 Stations	-2,-1,1,8,10,12,14,16,18	About 0.8M/S	8.7s	42.2s
B2	18 Floor 18 Stations	1,8,10,12,14,16,18	About 0.8M/S	8.7s	40.2s

III: Demand PROVISIONS

1. Customer outbound input.

2. Set up the elevator operation log, and can output in real time.

3. Can better simulate multi-ladder operation, explore the optimization algorithm.

Four: Optimization algorithm discussion

Based on set selection and group control technology, it is set up artificially. Set parameter reference Kone company parameter document and Merck sub-code.
