Bosch equips the new Chengdu Tianfu airport with panoramic cameras and audio

Described as China's new mega-airport, Chengdu Tianfu International has relied on the technology of Bosch with the installation of 1.000 panoramic cameras and 9.000 loudspeakers for public address and voice alarm system.

The objective of the Bosch project for the new Chinese mega-airport Chengdu Tianfu International is to ensure the safety of passengers and facility staff, in addition to improving comfort and ease of use for travelers on their journey.

Located in the Chinese province of Sichuan, Chengdu Tianfu International, is at the service of this emerging city for commerce, culture and finance, and according to forecasts it will be the third busiest for air traffic after Beijing and Shanghai.

Installation of audio and video technology Bosch was adapted according to the special architectural requirements of the airport complex, which opened last June, including two terminal buildings that reference the ancient Golden Sun Bird totem pole found in 2001 at the Jinsha ruins of Chengdu city.

Due to the unique design of these buildings, with very high ceilings, 'standard' or more traditional security cameras were not appropriate for the installation, since the image quality would not be good and would produce a poor viewing angle.

The solution has been Bosch panoramic cameras Flexidome, that were integrated into the interior design of the airport building, They were installed on walls or hidden in information panels without problems.

Each panoramic device is capable of monitoring a semicircular area with a radius of 25 metros, with a detection range of the same distance and a viewing angle of 180º. This allowed the airport to install many fewer cameras, reducing the total number by a 75%, of 4.000 standard equipment for a typical project of this scale to 1.000 panoramic cameras, also saving wiring and assembly costs.

Besides, Bosch Flexidome panoramic cameras use only one lens, which improves shine, color and clarity, compared to other panoramic devices on the market, which usually use four lenses, which reduces image quality.

The precision tracking capabilities and high-quality video transmission of these panoramic security devices also free up human resources for the airport and allow incidents or events to be monitored without additional staff on the ground..

In the flight area, the airport has installed four Dinion IP cameras with 4K resolution to monitor the track. Since this area is very large, The option has been to use assembly software to combine the images from these four cameras and achieve a complete image covering the entire track., which allows the entire takeoff and landing process to be monitored in Chengdu Tianfu.

Customer experience with intelligible acoustics

As the interiors of the terminal buildings have many glass surfaces that cause sound reflections, Chengdu Tianfu needed to determine how to deliver a high level of speech intelligibility in its messages with minimal distortion, no matter where the passengers were.

The design team ran acoustic simulation software to determine how many speakers were needed to cover the terminal areas., as well as the location of the audio matrices.

For flight announcements, as well as for voice alarm and evacuation, more than 9.000 speakers, that cover seven hundred transmission zones and that are integrated through a I preside over the system de Bosch, ensuring passengers can clearly hear announcements throughout the terminal.

Besides, announcements can be transmitted accurately and clearly to passengers traveling from other areas of the airport complex. Specifically, the voice and public address alarm system Bosch Present deployed in the adjacent hotel has been integrated with the rest of the installation, so passengers can be alerted of ongoing airport events.

As part of the project, Bosch has also provided the wireless conference system Of those who say for adjacent airport offices.
