Data Acquisition Interface Design and Implementation of Diode Testing Equipment

摘要

Diode testing is a very critical part of the production process. Although traditional diode test equipment is intelligent and able to separate substandard products, the inspection data generated by it can only be viewed through a small LCD screen or manually recorded, but can not be collected and stored. We improved CPU board of 700 series diode test equipment, extended one RS232 communication interface, realized remote testing data collection and storage through data acquisition software, and provided technical basis for decision-making through statistical analysis.
