3onedata help Weihai city utility tunnel project to build reliable communication network

 

In released 2016 national pilot building utility tunnel cities list, Weihai, a closest city from China mainland to Japan and South Korea, the birthplace of the first Chinese modern navy - Beiyang navy, the site of sino-japanese war, one of the most suitable living coastal city, obtained the fifth to become one of 15 cities.As a global industrial network solution provider, 3onedata provides a reliable communication network for Weihan utility tunnel project with integrated industrial Ethernet solution, which helps the control center achieve the integrative, intelligentized management and operation to the overall system.

 

Background

 

There are 11 small items ,containing old town and new eastern-coastal town, with total length of 34.15 km and a total investment of 3.159 billion RMB, including water supply, recycle water, electricity, heating, communication (including broadcasting and TV), sewage, rainwater, gas and others, totally eight categories of pipeline enter into the tunnel.

 

In 2016, the utility tunnel has been built 10.53KM, and deployed various categories pipelines and accessory equipments, such as power supply, water supply, telecommunication, heating supply, drainage and more. The control center, as the brain to monitor and manage the utility tunnel, integrating the information transmission, management coordination, security surveillance, remote control and etc, combining fire alarm equipment, security equipment and more, achieve the real-time monitoring to all kinds of data in tunnel, find problem and handle it timely. 3onedata provide a complete industrial Ethernet solution for automation control system of utility tunnel control center.
