The main tasks of the surveillance and evacuation solution were to provide video monitoring and passenger movement control on trains and in stations. This included providing public information while guaranteeing increased passenger control and safety, as well as the management of any system alarms and diagnostics together with continuous event recording.
Ansaldo STS, who was in charge of designing the video surveillance and public address system, supported by System integrator Tyco, chose to address the challenge with equipment from Bosch Security Systems, whose solutions have been adopted worldwide. This resulted in the installation of 400 vandal resistant FlexiDome cameras, 10-bit digital processing technology, video and audio signal transmission encoders, as well as ten iSCSI storage units. The Praesideo system was selected as the evacuation component and installed in each station, connected via LAN. All sub-systems operate independently, even in the event of a network failure or other outage, providing maximum operability and thus maximum security. Finally, all the systems supplied by Bosch were integrated via a software development kit (SDK) in the control room to form one complete solution.
This means that Milan’s fully automated M5 line can be controlled by a single operations center, which processes all the information centrally. The center is able to issue all the necessary commands to ensure the correct functioning of the line, the safety of the passengers, timely maintenance measures, and the optimum use of operational personnel (mobile agents). As a result, the Italian city can rely on modern, LAN-based security technology for intelligent traffic control coupled with the highest standard of safety.
