AI Technical Summary

Technical Problem

In existing motor testing processes, fixed timing control based on static open-loop cannot adapt to the electrical coupling between multiple power supplies and real-time load fluctuations, resulting in electrical shocks that can damage test equipment or the motor under test.

Method used

A fully closed-loop control system is adopted, including a real-time data acquisition module, a timing logic closed-loop control module, a power drive execution module, a fault protection module, and a host computer interaction module. Through multi-scale attention perception method, graph reinforcement learning timing scheduling algorithm, dynamic priority soft instruction queue method, and predictive protection method based on spatiotemporal graph convolutional network, the power supply power-on and power-off timing is dynamically adjusted to achieve real-time calibration of electrical parameters and fault prediction.

Benefits of technology

It effectively eliminates electrical shocks, achieves balanced scheduling and fault prediction of power bus resources, avoids secondary electrical shocks caused by protection actions, and improves the reliability and safety of motor testing.

Abstract

This invention discloses a power-on / off timing control system for a motor test power supply based on data acquisition. The system includes a real-time data acquisition module, a timing logic closed-loop control module, a power drive execution module, a fault protection module, and a host computer interaction module. The real-time data acquisition module acquires electrical parameters and status data; the timing logic closed-loop control module abstracts the multi-channel power supply as graph nodes and the electrical coupling relationships between channels as edges, dynamically calibrating the power-on / off timing nodes of the multi-channel power supply and generating timing control commands by using a graph neural network and a deep deterministic policy gradient network to minimize the electrical impact penalty function; the power drive execution module manages the power supply on / off according to the commands; the fault protection module performs feedforward protection; and the host computer interaction module configures rules. This system transforms static open-loop timing into dynamic closed-loop timing, enabling timing nodes to match the actual electrical transition process and eliminating transient electrical impacts generated during power-on / off switching.
