Embedded Systems Applications
The module begins by evaluating the features of embedded systems. All the main features of embedded systems are analysed. The applications will be based around an Intel 8051 based device. All the main aspects of embedded systems in terms of real time operating systems, peripheral control, error handling and hardware interfacing will be examined and analysed in detail.
The C programming language for use in embedded systems will be used as the high level programming input.
MCS 51 assembler will also be used to provide low level programming of the 8051
The mechatronic approach will be stimulated and rewarded by applying it to the design of a practical product or process that would offer some enhanced performance compared with other alternatives.
Mechatronic design process:
Definitions of Mechatronics, advantages of microprocessor system control, Mechatronic design process: product and process design applications, advantages of Mechatronic design approach. Evaluate current technology developments that have improved mechatronic design of products or processes.
Design a product or process using a Mechatronic design methodology: Conceptual design: user requirement specification, embodiment design, standards, safety regulations: selection of measurement system, controller hardware and software, actuator system, signal conditioning, human-machine interface; design of application program; integration of components.
Evaluate a Mechatronic design application: Reliability, accuracy, speed of response, productivity, robustness, ease of maintenance, minimisation of capital and running costs, ease of manufacture, product quality, minimisation of pollution and waste products. Evaluation of design procedure.
The student will learn about important elements of project management, such as planning, control, cost, problem solving skills, report writing and defend the outcome during a viva session. The project is normally completed during 13 weeks of full time research or part time equivalent, 26 weeks.
