5 On the 9th, the public announcement of the successful bid for the procurement and integration project of the comprehensive monitoring system equipment for Qingdao Metro Line 4 was completed. Hisense Network Technology triumphantly won the bid for the project's BAS system, which utilizes an independently developed, domestically controlled PLC from Aoto Technology. Notably, the PLC brands recommended by the project owner previously leaned heavily toward leading international brands such as Siemens and AB. However, Hisense Network Technology carefully selected Aoto Technology's NA400+NA2000 solution, further solidifying Aoto Technology's strong position in the rail transit industry and highlighting the company's superior product quality as well as its excellent cost-performance ratio.
The Qingdao Metro Line 4 project, running from the Qingdao People's Auditorium to Dahe Dong Station, spans a total length of 30.7 kilometers and includes 25 stations. With an investment of 21.11 billion yuan, the line is expected to open by the end of 2022.
