The Safety Monitoring System for the SND@LHC Experiment at CERN
摘要
At the forefront of particle physics research, the SND@LHC experiment stands, strategically positioned 480 m downstream of the ATLAS interaction point within the LHC tunnel. Within this pioneering experiment, the SND Security Monitoring System (SND-SMS) acts as a vigilant guardian, employing IoT technology to safeguard the experiment's integrity and operational stability. Utilizing a network of Arm Cortex-M7 MCU and Sensirion SHT31D sensors, SND-SMS meticulously monitors environmental parameters such as temperature, humidity, and smoke levels across the experimental apparatus. Powered by ARM RTOS Mbed OS firmware and MQTT protocol, this system orchestrates real-time data collection, alarm classification, and initiative-taking safety measures, ensuring prompt responses to anomalies, from minor deviations to critical events, thereby upholding the SND@LHC's safety standards and operational efficiency.
