3. Trend – Concept
In recent years, Mihajlovic Soft increasingly engaged in the development of software systems that manages and controls electronic systems
Such electronic systems can be classified as embedded systems
The concept of designing such systems is suited to our country environment in which the most cost-effective way is to design a relatively simple (dummy) hardware and reliable (smart) software
Harware can only perform few simple operations
More complex operations, management and control of the whole system are performed by software

4. Characteristics of these software solutions
Software solutions for controlling and managing electronic devices are quite different than a common desktop applications
Reliability
These solutions are often found in systems that are expected to work flawlessly for years
Because of that software has to be developed and tested more carefully
Real-Time Concept
The software must be able to respond instantly to a new event / situation

5. Advantages and disadvantages of the "dummy hardware - smart software" concept
The advantages of this concept are numerous:
Cheaper development (development of software is generally cheaper than the development of specific hardware)
Flexibility (easier to change functionality of the system)
Easier and faster recovery due to errors (it's easier to reset the application, than all devices in the system)
It is easier and faster to find and debug errors
Reusability of code parts (eg communication with devices part of code, while the hardware is more difficult to re-use)
Disadvantages:
Speed (hardware control is always faster than software)

6. In practice ...
In the past few years, our company has been oriented to the development of software solutions that controls hardware devices in order to solve many nowdays problems.
Some of these solutions are:
IQOS – Information and Queue Organization System
Automatic management and payment system for closed parkings
Gas pump station - management and payment system for fuel dispensers
TLog – software support for speed enforcement digital video laser radar
This presentation describes two such solutions as follows:

7. Parking system - Parking is fundamental problem in large cities.
- By implementing such a system, it defines the concept of regulation of parking which can also be extended and improved, according to new requirements and other changes.
This system provides :
effective control of the operators
parking payment
vehicle access control
increase in vehicle safety
minimum waiting of vehicles on ramps
 centralized management of parking lots
possibility of online checking for free spaces
possibility to reserve parking space

8. Parking system - description
The system consists of an central base (usually at the city level) and one or more parking lots located at various locations in the city
Parking lots operate as independent systems for the parking payment, with different hardware configurations
 Each parking lot may have a particularly defined payment system: the type of card (bar code or RF), the opening hours, tariffs and vehicle category
Payment is made with two types of cards for identification:
barcode card exclusively for hourly payment
proximity cards for other types of payment: prepaid, postpaid, free     card for a certain period of time or number of entries
The software manages all elements of hardware devices and provides access control and payment for parking on one or more parking lots in the system

9. Parking system – elements
System consist of following hardware devices:
Entrance / Exit Terminal
Entrance inductive loop
Entrance button
Bar Code printer
RF cards reader

12. IQOS - Information and Organization Queue System
IQOS (Information and Organization Queue System) is a electronic queue management system which also serves as information provider to customers and employees in counter halls and offices.
IQOS represents a technical solution for long queues in waiting rooms and provides to customers and employees working atmosphere without the crowds, stress and high-tech organized way of doing business with the equal distribution of work among employees.
System provides:
No crowd and no stress in waiting rooms,
Information to customers,
Guarantee confidentiality of information at the counter,
One service – one queue,
All menus, papers, dialogues and software are with multilanguage support,
Additional software modules and services are developed (centralized monitoring, SMS alerts...),
The system is completely modular (hardware and software).

13. IQOS - description
User console (terminal, ticket dispenser) is used to generate tickets to the clients as well as to provide information to customers with the ability to print parts of information.
Ticket is generated after the client selects the desired service offered on the touch screen. Terminal prints the next number (ticket) by using a thermal printer.
After taking the ticket citizen / client is waiting for his number to appears on the right counter display.
Counter terminal is a set consisting of display and control console.
With control console counter officer can change currently status and call next one in the queue - line.
Central display is usually LCD or group of display units mounted in the waiting room, showing to clients information current status, the average processing time and client related information.
Central computer controls the whole system: central displays, displays on the counters, control consoles and process information gathered from terminals.

16. IQOS – Advantages
Multilinguage support (all menus, papers, dialogues and software have a language support)
Guarantee confidentiality of information at the counter
System is completely modular (hardware and software)
Touch screen on the user console (terminal)
Very intuitive and simple terminal interface
Flexible terminal interface with the changeable design options to specific customers
Possibility of design adjustments of the terminal itself
Controlling a large number of counters (127 counters on a single controller)
Voice support for automatically calling the next in line
Large, highly readable displays
Easy-to-use control console
Printing of tickets and necessary information
Easily to customize the system through the admin application
Generated reports can be used to monitor and analyze, and thereby to improve business process

17. SUMMARY Both systems can be completely realized as hardware controlled
Apllied software concept brought:
Cheaper development
Simpler development
Scalable systems
Greater flexibility
Easier maintenance
Easier and faster way to find bugs and debug
