This module will provide the student with an in-depth knowledge of sensor instrumentation and suitable monitoring and control algorithms, in relation to Agri-Machines.
Note: The emphasis on this module is primarily on the Control and embedded systems programming as well as Arduino technology in conjunction with Labview.
- Electronic Sensing Elements :
Introduction to electronic sensors; temperature, humidity, sound, lux, movement, pressure, Lidar and accelerometers.
- Analogue Signal Conditioning:
Sensor signal conditioning in preparation for digital conversion. Analogue filtering and Instrumentation amplifiers.
- Analogue-to-Digital Conversion:
Basic overview of ADC process, resolution, sampling rates, Nyquist frequency, input voltage range.
- Control Systems:
Basic control algorithm development. Evaluation of input data, data processing, control output generation.
Whorkshop (30 hours):
- LabView® Development Environment:
Introduction to LabView software. Basic control circuits. Introduction to LabView Data Acquisition cards. Digital and Analogue data Acquisition. Basic sensor input, digital signal processing and control output.
- Introduction to Embedded Systems:
Arduino and embedded sensor systems. On chip ADCs, Digital I/Os, Comms with PC.
- Embedded Data Capture and Processing:
Integration of sensing elements in an embedded system. Practical data capture, processing and control.
Students who do not possess a passing grade or the required attendance at the semesters end will be required to sit a computer based exam. In the event a student fails module due to not meeting 80% attendance at practical/workshop sessions outside of extenuating circumstances, then repeat attend is required at next available offering of the module.
