Case Study for Value Added Services
Value Added Service: A Retrofit Custom Design Job for Type 'A' Auckland Metro Trains.
Problem:
The Onboard Passenger Information System in Type 'A' Auckland Trains had ongoing data transmission errors on their LED signs. Upon system analysis we found that these errors were due to a combination of existing weak LED sign communication module and the data cabling setup in these trains. Replacing the existing data cabling was a difficult task and would result in lengthy down-time for our customer, so this was not an option!
A challenge was to improve data transmission reliability utilizing exsiting data wiring and LED displays.
Solution:
We worked closely with our client carrying out in-depth analyzing of the situation. Then we designed a customized data module in-house to trial on-site as a prototype. Various versions of this module was tested both on-site and in-house until the results ensured 100% data transmission reliability over existing data cabling setup.
Working with our client various new test procedures were developed that assisted in successful install. Based on the extensive testing and analysis a final version of the customized data module was developed. This data module was rolled out for all Type 'A' train LED signs.
As a result of collective team effort the third-party LED signs on Type 'A' trains are performing without any hindrances.
