What is HMI ?

Human Machine Interface

MMI

MAN Machine Interface

^


4/35

Do, and where we need HMI ?Almost everywhere !

When we are hungry

We use HMI (classic one).

When it started ? HMI use started long ago, with first controlled

machines This work is focused to the computer HMI

The computer HMI came with first computers

n ear y rs commerc a compu ercontrolled processes came to the market,centralized control, one mainframe computerand network of terminals

Today, Windows environment is the mostcommon, distributed control and computernetwork in process control

^

How it started ?

First user interfaces were VERY simple :

- execute command

INPUT CODE : _12

INPUT VALUE: _

- get information

INPUT Address: _VALUE: _

commercial computer

control systems

Dos HMI were in

use in late 80s and90s of the last century

Windows HMI today

VDK 1000 basic concept

3 DOF Cartesian manipulator (Parker motion group)

3 DOF Gimbal unit * 3 fingers hand *

Flip regrip station with 2 fingers hand*

Automatic rouge application * Force controller *

Vacuum precious metal collecting **

* new (re)designed components patent pending** non standard application

Rouge applicator

Automatic rouge applying

Four rouges (upper twoon the picture)

Independent action for

every rouge Rouge in/out sensors

Manually adjustable

force for each rouge Covers

Upper tools rouge mechanism

Force control

Ring

Polishing wheel

Controlled force(air guided cylinderwith zero friction)

Vacuum

Water vacuum is used

for precious metal collecting

Machine cabin is

sealed

Ring positioning

Tray with 120 positions was designed

3 prongs hold each ring

Ring scratching is

avoided by use

Software tools

To develop VDK 1000 system software and HMI,

the following tools are used: Delphi 2005 (Borland )

7

SmartSCADA tool version 3.0 (TechnoSoft )

OPC client server

SM state machine

SmartSCADA System tools

SmartSCADA Visual controls

HMI programming

Think about the user

General recommendations

n as ou are a user an , en e pyour self

Simulate real conditions

Test as much as possible All available time spend repeating tests

^


28/35

VDK 1000 HMI is user friendly

Controls are organized in logical blocks

All necessary control options are included All controls are intuitive and easy to use

monitor size Screen is not overloaded by data

Help or just a hint is provided for every control

on the screen.

31/35

All necessary controls are included

Production window has sequential control

To start production it is necessary to check all conditions (all infopanels have to be green)

Production can be started only by following steps in given order

All analog parameters are available during production

^


32/35

Controls are easy to use

Right mouse click invokes popupmenu with appropriate actions

Manual controls for rouge operations-Control buttons-Position lights

Manual controls for vacuum andtool control

- Control buttons- Control lights- Speed control- RPM and Load info

Drawings are simple but functional

Tool position setup window

Info panel- Current configuration- Current hand position- Current hand orientation

- Simple drawing- Edit fields- Control buttons forcurrent position copying

Avoided delays

Communication delays Hardware optimization of hardware protocol communication

is applied Software communication is optimized to avoid unnecessary

data traffic

Database delays Overloading database is avoided by data base size restricting

and automatic database archive

Computer hardware delays Memory software is optimized to avoid use of virtual

memory

Hard disk software is optimized so that hard disk usage isminimal Video card graphics user interface is optimized
