DRAFT PROPOSAL FOR FINAL YEAR PROJECT 09/10
DESIGN OF A GENERAL PURPOSE DISTRIBUTED INDUSTRIAL AUTOMATION SYSTEM
DISTRIBUTED INDUSTRIAL AUTOMATION SYSTEM
The objective is to create a distributed automation system bypassing the need for a dedicated specialized controller like a PLC.
The idea is to find and quantify the specific requirements where such a system can be implemented instead of specialized controllers.
It is observed that for some instances of control and data acquisition, the need for specialized controllers doesn’t exist, but due to bad engineering they are deployed.
The project proposes to create a system from ground up with respect to software as well as hardware.
To find the inherent weaknesses attached with this concept and to find the solutions to them.
1. Serial to RS485 converter module.
2. Digital Input modules
3. Digital output modules
4. Analog input ( 0-10V/ 4-20mA) module
5. Analog output ( 0-10V/ 4-20mA) module
6. Software to interact with the serial port and its user friendly API to simplify control algorithm programming and execution in the PC.
1. Implement modbus protocol at the application layer so as to make the system be compatible with the industry standard.
2. Develop modules for widely used Inputs and Outputs
• Thermocouple (k/j type) inputs
• Load cell inputs
3. Develop suitable software to configure these proposed modules.
4. To develop a user friendly, intuitive front end GUI to seamlessly integrate control algorithm development and HMI development.
PROPOSED RESEARCH AREAS
1. Ways to optimize the communication speed of a distributed system
2. Analyze how EMI affect the system. Propose and implement solutions to overcome them.
3. Find the most suitable operating system (general purpose) to handle real time I/O as relevant to industrial automation.
4. Quantitatively analyze the speeds that can be achieved. Research how the performance of the system varies with factors such as number of daisy chained modules and installed IO capacity. Try to formulate simple formulae to connect all these factors and derive the maximum latency.
Given the importance of automation in industrial processes, the project will give us a practical insight into the heart of Industrial automation.
