In May 2025, we completed a temperature monitoring system for trenches in the MCC and SCADA rooms of Company L's control building.

One channel monitors the second-floor DCS room, while a second channel monitors the first-floor MCC room trenches through installed optical sensing cables.

DTS equipment is located in the system room, and an HMI PC with a 27-inch monitor is installed in the operators' control room.

After installation, cooling and heating tests at multiple equipment locations verified that positions on the monitoring display matched the actual site.

An NTP server and GPS antenna in the system panel synchronize the system clock to GPS time. An LTE modem sends immediate SMS alarm notifications, and delivery to operators by alarm level was verified.

Topics: MCC and DCS rack rooms, trench temperature monitoring, distributed fiber optic sensing, GPS time synchronization and SMS alarms.
