Airport Broadcasting solution
Description of project
As a large transportation base, the main function of the airport public address system is to broadcast the flight dynamic information, airport business information, special announcement and emergency events in the public area and office area of the airport terminal, but the traditional simulation public address system has been unable to meet its needs. With the development of Internet technology, networked public broadcasting system emerges at the historic moment. The system integrates background music, public broadcast, information release broadcast and emergency broadcast to meet the needs of the airport public address system. In addition, the system is based on computer network technology, modular and layered construction, highly integrated, intelligent public address system, this advantage makes it the first choice of airport public address.
The control center
The main control room of the system is composed of audio source unit, network broadcast server host, fire terminal, power amplifier and loudspeaker, etc. Strong network broadcast server host built-in radio matrix system effectively solve the problem of multichannel audio broadcast, puts forward a set of scientific radio broadcast content priority process control and partition management, avoid the flight broadcast information resulted from the intensive and large area of abnormal queue congestion, ruled out important broadcast information is ignored. Large capacity program source space is built into the host of network broadcast server, and different program sources can be played in different functional partitions. The main engine can be open to the interface to accept the centralized control of the airport upper-level system. In addition, the system through the integrated fire terminal linkage with the fire control center, when having special accident or fire, after the terminal receives the center of the fire alarm signal feedback to host the compulsory system to cut off the background music and business into the radio alarm working state, and through the emergency broadcast receiver or broadcasts fire pre - recorded voice evacuation, the emergency information, Guide passengers and all people safely away from the scene, prevent the scene disorder, will reduce the loss to the minimum.
Radio partition
The system is divided according to the physical location area and the functional area of the airport, such as the runway, departure hall, check-in, ticket purchase area, rest area, office area and other areas to divide the broadcasting function area. Network decoding terminal, power amplifier, main and backup amplifier switcher and loudspeaker are configured in each functional area. According to the national standard "Technical Specification for Public Broadcasting System Engineering" for background music and emergency broadcast sound pressure level 1 standard, outdoor remote horn is equipped in the runway area; High-definition horn loudspeakers are installed in the terminal hall, check-in area and ticketing area. Coaxial roof suction loudspeakers are installed in the rest area and office area. Enabling voice broadcast messages to be heard by every passenger and crew member. Considering the importance of the airport voice broadcast, the broadcast system is not allowed to release information or stagnate, and each broadcast partition is configured with the main and standby power amplifier switcher. When the main power amplifier fails, the switcher will automatically detect and switch to the standby power amplifier to ensure the normal operation of the airport network broadcast system.
