AI Technical Summary

⚠Technical Problem

Large-scale point light source fault detection is costly, complex to deploy, and inefficient. Existing technologies require the integration of an RDM chip into each point light source, resulting in huge retrofit costs and low detection efficiency.

⚗Method used

By dividing the control loops, the server calculates the current threshold and the control module controls the power on and off of the control loops. Combined with the current detector to detect the total current, a multi-level management module is used for hierarchical management, and the current threshold of each control loop is dynamically calculated to determine the fault.

🎯Benefits of technology

It achieves rapid and accurate fault detection, simplifies the system structure, facilitates implementation, reduces costs, and improves detection efficiency.

Abstract

The application discloses a large-scale point light source fault detection system, which comprises a server, a control module and a current detector. The server is used for current threshold calculation of each control loop according to the attenuation rate of each control loop and sending a first control signal to the control module. One control loop is formed by connecting control lines of a plurality of point light sources in series. The control module is used for receiving the first control signal sent by the server and controlling on-off of at least one loop in the control loop. The current detector is connected in series in a total power supply loop of the large-scale point light source and is used for detecting total power-on current. The server is further used for judging whether the current power-on control loop has a fault according to the total power-on current detected by the current detection device and the current threshold of each current power-on control loop. The application solves the problem of high cost of the existing large-scale point light source fault detection.
