DAC554 - Data Acquisition Interfacing and Control

Subject Title
Data Acquisition Interfacing and Control

Subject Description
DAC554 introduces students to the practical aspects of using PC for real-time data acquisition and digital control. It develops the skills in programming the PC interfaces such as serial, USB, and Ethernet for Data Acquisition and Control (DA&C) for applications such as servo control, and provides the fundamentals of I/O techniques and PID (Proportional + Integral + Derivative) control. A lab environment which consists of servos, servo digital boards, units of interfacing ports, digital oscilloscopes, and PCs is set up for hands-on lab assignments and project.

Credit Status
One subject credit in Computer Engineering Technology Program and Electronics Engineering Technology -
Control Systems Option program.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Describe PC buses, I/O ports(such as serial port, USB port, and Ethernet port), and interfacing cards

2. Describe sensors for analog signals, A/D converters and D/A converters

3. Design simple IIR (Infinite Pulse Response) low-pass filters

4. Understand absolute encoders and incremental encoders

5. Understand software interrupts and hardware interrupts

6. Interface a temperature sensor to a PC and write program to display the temperature on PC monitor

7. Describe a digital control system which includes components such as servo, servo digital board, USB interface, and PC

8. Explain the working principles for digital proportional control, PI control, PD control, and PID control

9. Evaluate the stability and system performance (such as stability margins, time-domain performance) of digital control systems by DA&C software and digital oscilloscope

10. Develop a practical digital PID control for the digital servo control system

11. Develop VB programs for DA&C via serial port, USB port, or Ethernet interface by calling third party DLLs.

12. Design and implement a digital control system consists of servo, servo digital board, USB interface, Interfacing unit, and PC

Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: http://www.senecapolytechnic.ca/about/policies/academic-integrity-policy.html Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website http://open2.senecac.on.ca/sites/academic-integrity/for-students to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.

Discrimination/Harassment
All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment. Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated. Information and assistance are available from the Student Conduct Office at student.conduct@senecapolytechnic.ca.

Accommodation for Students with Disabilities
The College will provide reasonable accommodation to students with disabilities in order to promote academic success. If you require accommodation, contact the Counselling and Accessibility Services Office at ext. 22900 to initiate the process for documenting, assessing and implementing your individual accommodation needs.

Camera Use and Recordings - Synchronous (Live) Classes
Synchronous (live) classes may be delivered in person, in a Flexible Learning space, or online through a Seneca web conferencing platform such as MS Teams or Zoom. Flexible Learning spaces are equipped with cameras, microphones, monitors and speakers that capture and stream instructor and student interactions, providing an in-person experience for students choosing to study online.

Students joining a live class online may be required to have a working camera in order to participate, or for certain activities (e.g. group work, assessments), and high-speed broadband access (e.g. Cable, DSL) is highly recommended. In the event students encounter circumstances that impact their ability to join the platform with their camera on, they should reach out to the professor to discuss. Live classes may be recorded and made available to students to support access to course content and promote student learning and success.

By attending live classes, students are consenting to the collection and use of their personal information for the purposes of administering the class and associated coursework. To learn more about Seneca's privacy practices, visit Privacy Notice.
