2022-06-30
On June 28, 2022, Qingdao Metro Line 4's "T20—Integrated Monitoring System and BAS System Joint Commissioning Project" was conducted for the first time at Buxi Station.
This joint commissioning primarily verifies the ISCS system's ability to monitor and control field devices via the BAS system, ensuring that all system equipment operates smoothly and in coordination—both during normal metro operations and in emergency situations.

During the first day of testing, the BAS system operated smoothly and reliably, ensuring the successful completion of the integrated commissioning. We are confident that the Aoto PLC, having successfully passed rigorous tests under high-temperature, high-humidity, and high-dust conditions, will continue to provide stable and dependable performance, safeguarding the seamless operation of the BAS system throughout the subsequent integration and acceptance phases. This will, in turn, contribute significantly to the smooth opening of Qingdao Metro Line 4!
