I have developed a portion of a multi-computer control software, forming an integral part of a fully automatic production line quality control system. That system has been built to perform 16 measurements on each production item, using proximity gauges, infrared sensors, vision and thread testers. Upon completion of all measurements, the results are evaluated against pass/fail criteria, and the part under inspection is moved to either "good" or "bad" part container. I have developed real time operating and application software, as well as the communication infrastructure for the system's two computers.

The following main functional capabilities have been developed:

 

• Touch-screen based I/O graphical user interface
• Control algorithms
• Programmable Logic Controller interface and communication handler
• Inter computer communication framework
• Status display, logging, and reporting
• Database operations
• Statistical analysis
• Real-time system operating framework
