Secured wireless communication for industrial automation and control

  1. 1. Embedded systems Ph:7842522786 9948887244 SECURED WIRELESS COMMUNICATION FOR INDUSTRIAL AUTOMATION AND CONTROL Vijayawada Hyderabad Page 1
  2. 2. Embedded systems Ph:7842522786 9948887244 AIM: The main of this project is to monitor and control of industrial parameters using wireless technology PURPOSE: The purpose of this project is to develop a wireless technology for industries for data acquisition of parameters like temperature, speed, voltage.

  3. 3. Embedded systems Ph:7842522786 9948887244 DESCRIPTION: Wireless communication is the transfer of information over a distance without the use of electrical conductors or wires. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications).It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Industrial users should consider the type of monitoring and control applications that are suitable for LR-WPAN technology such as Zigbee. Reliability, security and performance are potential challenges when designing and deploying wireless technologies and factors such as EMI/RFI and multi-path fading in industrial environments can be specific issues to consider. Zigbee provides proper network topology, and it overcomes all problems in industries caused due to environmental issues [10]. We tested Zigbee networks in various environmental conditions by using four node star networks for industrial applications like speed and direction control of D.C motor, Illumination control of incandescent lamp and closed loop water path temperature control. It was seen that error free proper communication was established between the processing unit and monitoring unit. In future we can also test other Zigbee Networks for proper wireless data communication TECHNOLOGY: ZIGBEE: Vijayawada Hyderabad Page 3
  4. 4. Embedded systems Ph:7842522786 9948887244 Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide range controlling applications and to replace the existing non-standard technologies. It currently operates in 868 MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps. It is used to verify whether user’s truncation is possible or not. One of the main advantages of this ZIGBEE communication is that it provides a noise free communication, the amount of noise added in this type of communication is very less compared to the other wireless communications. SOFTWARES: Embedded C Keil uvision Express PCB Flash Magic HARDWARE: Zigbee Micro Controller Sensor(Temperature ,LDR ) DC MOTOR with drivers RESULT: Hence, we designed and implemented a wireless Technology based on the zigbee for controlling and monitoring system.
