Beijing West Railway Station

The Beijing West Railway Station is a modern passenger transportation hub, representing a crucial urban infrastructure project in both national and Beijing's "Eighth Five-Year Plan." Covering an area of 510,000 square meters with a building area of 170,000 square meters, the station boasts a towering waiting hall reaching 90 meters in height, designed in the shape of the Chinese character "品" (pronounced 'pin'), with a total investment of 23.5 billion yuan. The station comprises 9 platforms, with a maximum daily passenger capacity of 90 pairs of trains or 600,000 passengers, making it one of the world's largest railway passenger stations. In recent years, with the continuous development of railway transportation, Beijing West Railway Station has become a crucial gateway for disseminating information from Beijing to the entire country and the world. Trains departing from here cover all major cities in South China, Southwest China, and Northwest China, establishing it as a vital railway transportation hub in China.


The broadcasting system is required to have high reliability, supporting hot backup for different system segments and compatibility with emergency and fire alarm broadcasting functions. The station's business broadcasting supports both automatic and manual modes, wireless broadcasting within specific zones, and a unified priority system—higher priority for high voltage, low priority for flat-level, and higher priority for late entries. The system also supports zone calling using code and electronic map methods, content monitoring, automatic device detection, and log queries, as well as voice call storage and retrieval.


The system utilizes the Q-SYS 500i core host as its central component, with hot backup for both the system host and power amplifiers. The PS-1600G gooseneck calling station is employed for station business broadcasting, supporting both automatic and manual modes. A digital interface connects the automatic broadcasting server and the broadcasting system, combining artificial voice broadcasting with wireless broadcasting within specific zones. The I/O Frame network audio interface device, along with CIML4/COL4 input/output cards, is responsible for processing and transmitting audio signals.
