Tools

Introduction

The Tools menu is provided for additional analysis features not directly related to the main calculations.  The following tools are available.


Kinematics

The kinematics tool allows you to select any trip, and the speed, acceleration and jerk.


Figure 34  Kinematics dialog


When you click on the Calculate button, an Excel spreadsheet is generated providing a detailed kinematics analysis of the trip including:

  • Flight time.
  • Maximum speed achieved during a trip.
  • Details as to whether or not the elevator reached rated acceleration and speed during a trip.
  • Flight times and door to door times from the Home floor to all other floors entered in Building Data using the specified speed/acceleration/jerk combination.
  • Distance travelled to reach rated acceleration.
  • Time elapsed to reach rated acceleration.
  • Speed at rated acceleration.
  • Distance travelled to reach rated speed.
  • Time elapsed to reach rated speed.
  • Numerical values allowing you to plot the distance travelled, velocity, acceleration and jerk profiles for the specified trip.

Count

Count is an application to assist passenger traffic surveys. It replaces traditional clipboards and forms for lobby and in-car surveys.  The observer who controls the software logs traffic.

Select Survey, Start from the Count menu.


Figure 36   Starting a new survey with Count

First you must choose a survey output file directory.

Then choose if you are doing an in car or lobby survey.  Select the car number or name of the Lobby level.  The names of levels are as defined in Building Data when you start Count.


Figure 37   Lobby survey display

For a lobby survey, select Passenger Enters each time a passenger enters a car.  Select Passenger Exits each time a passenger exits the car.

If there is a large load (e.g. hospital patient in wheelchair with carer), you can treat them as a single large passenger using the Passenger Multiple, i.e. set to 2.5 if the load is the equivalent of 2.5 regular passengers.  Or you can use the parameter as a code, e.g. 1 for a single passenger, 2 for a passenger in wheelchair and carer, 3 for a passenger in a bed with porter, etc.

NOTE:  If large queues form in the lobby and do not clear quickly (say 5 minutes), the measured traffic entering and exiting the car, will underestimate the peak arrival rate, which is normally processed in 5 minute periods.  In this instance, it would be more representative (but more difficult) to log passengers joining the queue rather than entering the elevator.


Figure 38   In car survey display

The in car survey requires the observer to be standing or sitting in the elevator.  Passenger entering and exiting the elevator are recorded in the same way as they are in the Lobby Survey.

The Current floor of the car is recorded with the Car Data Up 1 floor and Down 1 floor buttons.  The names of levels are as defined in Building Data when you start Count.

There are individual buttons to record:

Parking Call

When the elevator moves to a floor without a call being registered and the elevator doors do not open.

False Stop

When the elevator answers a call, the doors open, but no passenger loads or unloads.

Refusal

When the elevator answers a call, but the passenger does not load because the car is too full.

Free form comments can also be added to the log file using the Add Comment button.


System Stimulation

System Stimulation provides a list of calls in a format that can be used to stimulate a real elevator system

Motion

Motion is a tool to assist in the comparison between ideal and actual kinematics.

Measurements using EVA 625 Ride Analyser

To measure actual kinematics you can use a stopwatch and a ride analyser, for example the EVA 625 Ride Analyser from Physical Measurement Technologies.

Using the EVA 625 Ride Analyser our suggested measurement procedure is:

  1. Start Ride Analyser and stopwatch at instant that doors start closing
  2. Take lap time on stopwatch when doors have fully closed
  3. Take lap time on stopwatch when doors start opening
  4. Halt stopwatch and Ride Analyser when doors are fully open

The measurements for distance, velocity, acceleration and jerk can then be exported from the Ride Analyser.

On the opening page of Motion (with the Ideal tab selected) you can enter nominal values of distance, velocity, and acceleration, jerk and start delay.  Also enter your measured times for door open and door close.

Measurements using Elevate Perform

Elevate Perform is an accelerometer which connects directly to the Elevate Motion application to simplify the measurement of elevator performance.  The measurement procedure is:

  1. Connect the Elevate Perform accelerometer to a laptop USB port.
  2. Click on the button in Motion to
  • connect to the accelerometer
  • indicate that the doors have started closing at the starting floor
  • indicate that the doors are closed at the starting floor
  • indicate that the doors have started opening at the destination floor
  • indicate that the doors have completed opening at the destination floor.

Motion will automatically “best fit” your Elevate Perform measurements to determine door times, velocity, acceleration, jerk and motor start delay.


Reviewing results

Use Next and Back to switch between the inputs, plots and tabulated results.

A control is provided to allow you to select which plot to view.

Distance, Velocity, Acceleration and Jerk plots are available.

To assist in lining up Ideal and Measured plots, further controls   are provided to adjust Ideal parameters incrementally while viewing the plots together.  When using Elevate Perform, Motion will align the plots automatically.

Once the Ideal and Measured plots are aligned, the Ideal measurements can be reviewed, and applied in Elevate simulations.

Select the Next button to see supplementary results and the data used to plot the Ideal curves.

There is some duplication between the Kinematics Tool and the Motion tool.  In a future upgrade all functionality will be provided though the Motion tool and the Kinematics tools will be discontinued.

Recorder

If you would like to create a video of your simulation to play outside Elevate, select the Recorder from the Tools menu before you start the simulation.  Once the simulation is compete (or stopped) the video file will be created and played.  You need to select Recorder before each simulation that you want to record.


Elevate Live Web Control and Fetch Log File

Elevate Live provides live elevator monitoring and logging over the internet or local area network.  Analysis of traffic demand and performance is provided by Elevate.

Elevate Live Web Control provides functions to configure Elevate Live.  Elevate Fetch Log File retrieves logging files so that the operation of the elevators can be replayed and analysed in Elevate.

Lift Simulator Server

This is a feature allows pedestrian modelling software to apply Elevate's simulation of elevator systems.

To use this feature:

  • Make a directory C:\Users\Public\Public Elevate
  • Copy C:\Program Files (x86)\Elevate 8\ExternalHallCalls.txt to C:\Users\Public\Public Elevate.  This file will be used to record the calls sent to Elevate.
  • In Analysis Data set the Number of simulations to run for each configuration to 1
  • In Elevator Data set the Number of Elevators to Specified
  • In Passenger Data set the Passenger Data Mode to File and select C:\Users\Public\Public Elevate\ExternalHallCalls.txt
  • On the Tools menu, select Lift Simulation Server. 
  • Select Analysis, Run or press the play button on the toolbar.

The pedestrian modelling software may then initiate calls which will be answered by the Elevate elevator group.

If you are a developer who would like to integrate your pedestrian modelling software with Elevate, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. for access to the demonstration project showing how to control Elevate.  

The install provided will create a folder ElevateLiftSimulator in My Documents. Build and run LiftSimulatorClient.exe to try the interface.  See LiftSimulatorClient.chm for documentation.
