  1. 1. Yarmouk University Computer Engineering Department WEB BASED INTERACTIVE EMBEDDED POWER PLANT MANAGEMENT SYSTEM Authors: P.AngelDeepa M.JeyaPrabha A.BrindhaSherly Presented By: Waed shaqareen Embedded systems design SPRING 2016 1W. Al-Shaqareen ©
  2. 2. Introduction • Power plant system (Generation station) defined as industrial station that utilized for generation and distribution of electric power in mass scale. • Web based interactive embedded power plant system use internet for controlling and monitoring control plants using internet browser. • The core of the system is embedded hardware device that has built in web server for data that served to clients via internet. W. Al-Shaqareen © 2
  3. 3. Presentation Outline W. Al-Shaqareen © 3 • The basics of power plant control. • Functional modeling for internet based control systems. • Interactive data-acquisition system. • Establishing a direct communication link between the client and the embedded device . • Broadcast IP address using FTP server. • Data management in the system. • Data management in the system ( joint management) • Data management security.
  4. 4. The basics of power plant control • To achieve remote monitoring in power plant control system we need to ensure that power generation basics are achieved: 1-protectionLife insurance for the plant and associated asserts. 2-Control. must be accurate. 3-Supervision provide both comfort and flexibility. • To achieve these basics we construct functional modeling for internet based control systems W.Al-Shaqareen © 4
  5. 5. FUNCTIONAL MODELING FOR INTERNET BASED CONTROL SYSTEMS. • Functional modeling defined as constructing model to achieve control system specification. W. Al-Shaqareen© 5 Advantages: 1- Access to the monitoring functionality independent from location. 2-Use of zero cost software on client side to across the information.
  6. 6. INTERACTIVE DATA-ACQUISITION SYSTEM • In this system we monitor and adjust using web browsers keep in mind that PC independent from location and platform. Data acquisition system has three component: • Embedded system • Server. • Clients. W. Al-Shaqareen© 6
  7. 7. INTERACTIVE DATA-ACQUISITION SYSTEM W. Al-Shaqareen© 7 • Data acquisition system relay acquired data to clients and the clients send requests through server. • The drawback for this system is that "Enormous amount of data transfer time would be consumed”. • Indirect communication between client and embedded devices
  8. 8. Establishing a direct communication link between the client and the embedded device This system eliminate the need for a central server and reduces the amount of data sent from the remote unit ,just queried data only transferred. Direct access for embedded system need IP address of embedded devices must be available at the client side. IP address choices: *Static *Dynamic. W. Al-Shaqareen © 8
  9. 9. W. Al-Shaqareen © 9 Static IP versus Dynamic IP Static IP“remote devices initiate connection by reporting it’s IP Dynamic IP address “Using DHCP server of GSM provider for every connection established” IP address must be Known to any clients requesting an access to the embedded server
  10. 10. BROADCAST IP ADDRESS USING FTP SERVER W. Al-Shaqareen© 10
  11. 11. Broadcast IP address using FTP server • Mozart ----------> DAS(Data acquisition system). • A script on embedded device is configured. • HTML file (index.html)placed on FTP server by ES under folder it’s name has hostname and acquired by client. • ES updates it’s information on FTP server after every reboot ,so IP address refreshed. W.Al-Shaqareen© 11
  12. 12. Data management in the system • Server sending all pictures to client through server on internet. • Text data like: coordinates, altitudes..etc are served from ES. • If data to be transmitted ,embedded module set to send image via GPRS and placed on FTP. W. Al-Shaqareen © 12
  13. 13. Data management in the system W. Al-Shaqareen © 13 ES used here work in X86 based standalone unit with four serial port and one parallel port and 16MB removable flash memory. Serial ports---->debugging purposes and test system functionality.
  14. 14. Data management in the system (joint management)  Multiple services available between server and client simultaneously .  Joint management is the only joint that directly communicate with web clients in control systems.  All control elements behind joint management.  If malicious hackers want to attack control systems ,they attack joint management rather than control systems.  This method will reduce the number of links with the internet into one . W. Al-Shaqareen© 14
  15. 15. Data management system security • The most serious problems results from connecting power control system to internet: 1- Hackers. 2-Unauthorized access. 3-System failure caused by viruses . 4-Server overload. WBCS(Web based client server) developed to allow authorized users via information network excluding unauthorized operation. • Targets of malicious WBCS: 1-Directly attack of controllers and devices. 2-monitor information network. 3-Obtain information for suggested attack method. W. Al-Shaqareen© 15
  16. 16. Secure WBSC • PKI(public key Infrastructure) suggested as one of the best methods to secure WBSC. • Protecting operation equipment achieved by single firewall for whole network. W. Al-Shaqareen© 16
  17. 17. Conclusions W. Al-Shaqareen© 17 • TCP/IP model used to improve the power plant control system. • Low operational cost and flexible for web based power plant control systems. • Productivity increased by using internet.
