3 INTRODUCTION  The World Wide Web has made it possible to send a lot of data from one side of the world to the other side in almost no time.  The use of the Internet for real-time interaction of the remote controlling and monitoring of the plants would give us many can advantages.  Two main problems should be faced before the web based control and monitoring can be implemented. 1.The aspect of time delay, which can lead to irregular data transmission and data loss. 2. The problem of security.

4 WHAT IS WEB BASED MONITORING AND CONTROL ?  The web based monitoring and control (WBMC) can be described as the whole of operations performed to control or monitor a system situated in a closed network.  It enables commercial data to their customers and managers.  Easily achieving the real time status of process plants, suitable for implementing advance control.  It allows controllers to directly talk to the internet.  It can be used to monitor and control smart devices from the internet.

5 PROCESS CONTROL SYSTEM HIERARCHY AND POSSIBLE LINKS WITH THE INTERNET

6 REQUIREMENT SPECIFICATIONS  Tasks, which require a deterministic timing regime should be avoided because they may not be achievable due to web-related traffic delay.  It is necessary to minimize the communication load between the Internet level and the existing control level.  Information exchange between process plants and Internet-based clients can be achieved through corporate systems.  Reliability and the possible system failures should be also considered in order to keep the system robustness from the system architecture point of view.

8 SYSTEM FUNCTIONAL MODELING

9 INFORMATION ARCHITECTURE  Resolution: Abstraction levels for data vary among all the levels in the architecture. The higher the level is, the more abstract the data is.  Reliability: Just as communication response time must decrease as one descends through the levels of the information architecture, the required level of reliability increases.  Reparability: The reparability considers the ease with which control and computing devices can be maintained.

10 ATTACK TARGET

11 POSSIBLE MEASURES FOR PROTECTING THE TARGETS 1.Establish sufficient access restrictions to controllers and devices, which are on the control network. 2. Use encrypted information within the information network. 3. Establish sufficient access restrictions to operations terminal. 4. User authentication by using only a password and ID in not sufficient.

12 SYSTEM ARCHITECTURE

13 HARDWARE DESCRIPTION  Power supply  Memory  EEPROM 24C04  L OW P OWER Q UAD O PERATIONAL A MPLIFIERS  Voltage Regulator 7805

14 SENSOR CIRCUIT ( COMPARATORS )

15 SENSORS USED  Over Temperature  Humidity detection  Gas leakage  Fire detection

16 ADVANTAGES  Increased distance, data sharing and data provision for monitoring and control systems  Enabling remote monitoring and adjustment of plants, enabling collaboration between skilled plant managers situated in geographically diverse locations.  The overcome of limitations of control in the distance between nations and regions  Data sharing, full-scale experiment through simulations before installing and cost reduction  When using WBMC for educational purposes the risk involving in a real laboratory may be avoided

17 CONCLUSION In this report the Internet based process control has been examined. Internet based control is only an extra control level added into the existing process control hierarchy. When designing an architecture the requirement specifications, user interface, universally platform-independent programming languages and security measures are important issues. Internet technologies can provide web clients a platform, not only for remotely monitoring the behavior of process plants, but also for remotely controlling the plants as well.
