Overview
Introduction
The communication network for each station in a railway line was independent and isolated from the other stations in the system, making it difficult for local sites, control centers, and third parties to manage and share important data and signaling information. This created a critical problem. To improve the system and provide smoother, better communication, embedded computers can be used to integrate railway station communication systems.
System Requirements
Backbone system for network redundancy
Built-in web server for real-time control and remote monitoring
Front-end communication computer for data processing and logging
Various devices must be well-managed and organized
Multiple communication ports for connecting devices
Easy development for system integration
Moxa Solution
Each station needs to communicate and send data to local sites, the control center, and/or third parties. As a result, a centralized monitoring network is required to integrate all of these remote and independent systems. Moxa's DA-662 embedded computer serves as an ideal front-end processor to collect data from relevant peripheral systems, such as TIS, PA (public address) systems, ACS, PG, CCTV (closed circuit television), PSD, AFC (automated fare collection), EMCS, BAS (building automation system), and FAS (fire alarm system). With such integrated and manageable communication systems, each station will be able to access and share data with the control center, as well as other stations, easily and in real time.
