Conveyor Control System ProjectPart of the requirements in a junior-level measurements & instrumentation course (for an Electricaland Computer Engineering Technology program) includes an end-of-semester design project. Onepossible project is the design and implementation of a conveyor control system. For this project, theconveyor simulator is pre-fabricated and equipped with a 24-volt DC motor mounted directly to aplastic spindle for driving the conveyor belt, a freely rotating plastic spindle for the opposite side ofthe conveyor belt, and two Plexiglass sides. Three IR reflective sensors (one in the middle and oneat each end) are used to detect the position of an object on the conveyor. The objective of theproject is for students to design the software (using LabVIEW) and hardware interfacing electronicsfor the conveyor control system such that it mimics the operation of a conveyor with beginning,stamping, and ending stations. Students are required to use a National Instruments data acquisitionsystem with analog I/O and digital I/O capability. This paper provides a detailed listing of theengineering requirements for the system and the functional test procedure for verifying properoperation of the system. An example of student work is provided, along with a project assessment.Recommendations are included to help ensure student success on the project. In addition, since thisconveyor control system is also designed by students in a sophomore-level PLC course, a studentassessment based on the comparison of the advantages and disadvantages for the PC vs. PLCcontrol is provided. The PC-based control system project has been found to be an effective end-of-semester project for two reasons. First, it integrates both hardware and software design whileutilizing information covered from prerequisite courses. Second, due to the slow responsecharacteristics of this system, PC-based control is suitable for this application.
