Shanghai Metro

With successful installations already in operation across Shanghai Metro's Line 6 and Line 9, access control specialist TDSi, in partnership with a distribution partner in China, later completed work on the system installation for the Metro's Line 7.

The Overview

Shanghai Metro is one of the newest and fastest-growing transit systems, with 162 stations and over 225 km of track running both above and underground. On average, well over two million passengers use the system every day – with the future expansion plans set to see that number increase to over three million.

Multiple Sites

The requirement

A key requirement in the specification for this particular project was for each station to operate independently of the server in case communications are lost.

Over the years, TDSi and its distribution partner have been tasked with developing and supplying fully integrated access control solutions for Lines 6 and 9. Each line is served by over 40 stations as well as its own Operational Control Centre (OCC), with around 2,000 doors secured and controlled by TDSi’s systems on each line. Line 7 was commissioned into service at the end of 2008, connecting the Baoshan District with the city centre and Pudong District.

The Solution

The access control solution for the project featured TDSi’s EXpert controllers, EXgarde Enterprise software platform and MIFARE® smart card readers. Specified for its proven performance in high capacity applications, the EXpert controller delivers a fully featured and networkable system.

Each controller has a capacity of up to 48,000 cards and provides fast and effective access control to projects such as the Shanghai Metro, which has consistently high volumes of users passing through multiple access points.

Featuring database replication for powerful disaster recovery capabilities and total peace of mind, EXgarde Enterprise allows all real-time events and system parameters to be stored both at the main server in the local OCC and each station.

The Result

Commenting on the programme, TDSi’s Managing Director, John Davies said: “The Shanghai Metro is a very significant and high profile infrastructure programme, representing one of the largest access control projects across the whole of China. With two lines in operation for over a year, we were delighted to have been awarded the contract for Line 7 – a real demonstration of the performance and quality of our systems”.
