Description
We present an online monitoring and track reconstruction system developed for a multi-detector MRPC (Multi-gap Resistive Plate Chamber) cosmic-ray test platform. Built upon CERN ROOT and deployed in a Linux environment, the system enables simultaneous performance evaluation of multiple MRPC detectors. It performs real-time track fitting using hit information, allowing users to add or remove detector modules flexibly according to experimental configurations. The graphical interface displays hit positions and firing patterns on each detector, facilitating rapid diagnostics of detector status and data quality. The software employs a modular architecture that supports both continuous data acquisition and offline replay, with online histogram updates and alarm functions for abnormal channels. Tested with a telescope of six MRPCs, the system achieves a spatial resolution better than 1 mm and demonstrates stable operation over long runs. This tool significantly improves the efficiency of detector commissioning and cosmic-ray muon tracking, and it is readily adaptable to other resistive-plate chamber arrays for future RPC experiments.
