The incident occurred very suddenly. That morning, shortly after eight, I had just brewed a cup of tea and was about to sit down when a call came in from the warehouse, saying that all the AGVs were unresponsive, their wheels trembling, with some smoking and others completely powered down. When we arrived on site, … Read more
In modern automation control systems, motors serve as the core actuators, and their control precision and response speed directly determine the performance of the system. The 51 microcontroller, due to its low cost, high stability, and abundant development resources, has become the preferred controller in many embedded projects.
