It is difficult to measure and evaluate the line profiles of shift drums, and a single piece of system engineering software is hard to quickly realize the task requirements for line profile evaluation in real time. With the .NET object-oriented programming interface technology, the algorithm for line profile evaluation is developed by Matlab, and LabView collects and analyzes real-time data. As a result, hybrid programming is realized and software for line profile evaluation is developed. The hybrid programming technology accelerates the process from the integration of control, acquisition, analysis, and other tasks to the actual deployment and application, and improves the development efficiency.
