Baiyun Airport Logistics Operation Control Center (CTOC) project is located near Guangzhou Baiyun Airport International Air Cargo Station, which is the practice of the construction of the province's airport logistics integration digital platform, using advanced information technologies such as the Internet, Internet of Things, artificial intelligence, cloud computing, etc., to introduce traditional logistics into the online network, realize the interconnection and efficient collaboration of information of all parties in the air cargo system, and promote the digital transformation and development of logistics companies.
Project Overview
The project is a new construction project, and Tianchuang has built an audio sound reinforcement system for one command and dispatch hall and one conference room of the logistics operation control center of Baiyun AirportCustomers have high requirements for the stability and convenience of the system, and require the system to achieve digital and interface control.
Solution
After conducting on-site investigations, Tianchuang engineers installed compact models on both sides of the curved LED screen in order to evenly cover the overall wide command hallColumn speaker CAH CM-88LAt the same time, it is installed in the upper position of the curved LED screen in the front field of the hallPoint source loudspeaker CAH CM-206IIEffectively complements the sound field coverage in the middle area of the hall and in the hallSeatsCeiling loudspeakers Biamp DX-IC6,,000 are evenly laid above the areaThe whole hall can not only maintain the same sound image, but also have a higher uniformity of sound field coverage. In the 31 seats in the hall, equipped with high-end condenser gooseneck microphones, the design of the long microphone rod, so that users can achieve high-quality and clear voice pickup without adjusting their attitude, and the hall is equipped with a wireless handheld microphone, users can move freely in various areas of the hall to speak. The audio processor and back-end power amplifier and other equipment at the core of the system are installed in the computer room near the hall, and the power management of the equipment is realized through the power sequencer.
The audio systemPowered by the AIWIA AXE-8000III digital audio processing server with the AIWIA AXE-16i OAudio processing interfacescompositionCarry out the access processing and routing distribution of various microphones, distributed, paperless, and first-class terminals in the hall and conference room, without configuring the mixer, provide 48V phantom power supply and automatic mixing processing for the 31 seat condenser microphones at the front end, and then transmit the mixed audio signal to the AIWIA audio processing interface through the Dante network audio protocol equipped with the audio information server, and the audio processing interface will transmit the audio signal to the CAH power amplifier and the first conference terminal and other equipment. The CAH amplifier drives the CAH loudspeakers and BIAMP ceiling speakers in the hall and conference rooms respectively for high-quality sound reinforcementThe audio of the two zones can be independent of each other without interfering with each other, and the mode can also be switched to achieve audio interconnection. Through the AIWIA audio information server, multi-scene storage can be carried out, and once there is a problem with the audio, it can be quickly restored to the original normal state with one click, ensuring the normal progress of command and dispatch, consultation, etc.
The open design architecture of the domestic AIWIA audio information server, the processing module can be freely dragged and programmed to form a flexible audio system link, and the AIWIA audio information server supports 8 card slots to customize the input and output channels, and the single machine can form a maximum of 32 analog channelsFinished the siteSeatsThe 31 condenser microphones are connected, and support up to 32 independent channels of AEC processing, and the internal automatic mixing module does not require manual intervention, realizing the situation that 31 microphones are fully open but no howling on the spotThe 32*32 Dante network channel equipped with the equipment, with the audio information processing interface, expands a larger number of analog input and output channels, which can realize the docking with other system audio signals, and is more suitable for the application of complex audio scenarios such as the command hall.
Acceptance
Through the powerful processing power of AIWIA audio processing system, the user's flexible demand for the command and dispatch audio system is perfectly realized, without the need to configure the mixer, so that the whole system becomes more concise, digital processing and interface control, which greatly facilitates the control and monitoring of the audio system by the user, and the uniform sound field coverage makes the command and dispatch information transmission more convenient and efficient.
