The scope of implementation of the airport internal communication system (hereinafter referred to as the internal communication system) mainly covers the new airport terminal. It mainly provides internal call service and dispatching service. The internal call service mainly provides voice communication among check-in island counters, boarding gate counters, business duty rooms of various departments, and various functional centers of the airport in the terminal building. The dispatching service mainly provides the unified coordination and command of the production support units of the airport based on the intercom terminal. The system has functions such as single call, group call, conference, forced insertion, forced release, call queue, transfer, pickup, touch-to-talk, cluster intercom, etc., which can make communication between staff members fast, easy to use and easy to operate.
The intercom system requires the use of mature digital circuit switching technology to build a stable and reliable communication support system for the airport. The system needs to have high reliability, high traffic processing capacity, high call processing capacity during busy hours, non-blocking calls, long average time between host equipment and terminal equipment, fast communication, high-definition sound quality, modularization, and various types of interfaces. Fully functional and easy to maintain.
System Structure :
The intercom system is mainly composed of an intercom server, an intercom terminal (including a dispatch terminal, a common intercom terminal, etc.), a dispatch system, and a recording system.
System function requirements:
1. The digital terminal mentioned in this technical specification refers to the user terminal based on digital circuit switching and adopting voice digital coding technology. Analog telephone refers to the standard DTMF user signaling telephone.
2. The system can be configured with a variety of communication terminals to meet the needs of new airport users. The calls are fast and agile, the voice is clear and undistorted, and the work is stable and reliable, fully meeting the needs of the production and operation front-line communication and scheduling.
3. The system has a scheduling function, and has a group scheduling function. Different types of consoles and user terminals can be configured according to the nature of the business department. The rich terminal scheduling function can be set to any user terminal at will to complete fast and efficient scheduling. .
4. In addition to the basic call answering function of the system, the user terminal has functions such as one-touch instant talk, no-operation answer, hang-up free (one party hangs up after the end of the call, and the other party automatically hangs up) and other functions. , The call connection time meets the call establishment time requirement of the dispatching intercom system, less than 200ms, one-touch instant communication, quick response, quick and simple call.
5. The system must have high-definition sound quality, and the audio frequency range of the system should not be lower than 15k Hz to ensure clear, loud and accurate dispatch calls.
6. The system must have good compatibility and can be connected to IP telephone terminals provided by other manufacturers, such as SIP standard IP telephones.
7. The system has the capability of fault monitoring. It can automatically diagnose and detect the key components or devices of the system, communication cables and user terminals, etc., and can detect faults, alarm, register and print reports in time, and can send the number of the faulty terminal to the designated on the user terminal. For common functional components, faults are located on boards and functional modules.
8. The system has flexible communication methods, and has special functions such as multi-party multi-group conference, group call and group call, call transfer, busy line waiting, busy intrusion and forced release, main operation call queue and multi-channel voice, etc. Realize special functions such as teleconferencing, issuing orders, broadcasting notifications, paging to find people, and emergency calls. And it can be set by programming, its operation is simple and the voice is clear.
9. The system has a multi-channel real-time recording function, which can be used to record the calls of various important business departments in real time, so as to replay the live communication at any time. High reliability, high degree of restoration, good confidentiality, no deletion and modification, and convenient query.
10. The system has a data signal user interface, which can support the input and output of control signals. It can realize the control of various data signals through the internal programming of the program-controlled switch of the intercom system, and finally realize the intercom system with customized special functions for users.
