Airport air traffic control system solution

1.                      Requirement analysis

The audio and video multimedia command and dispatch system, launched to meet the needs of aviation dispatch, provides comprehensive dispatch methods including voice, image, video, data, conference style interaction, etc. to dispatchers at all levels. During the implementation of dispatch work, dispatchers at all levels can satisfy the sense of presence and interaction, such as face-to-face communication, and can timely obtain the required data, information, on-site scenes, and communication platforms, thus completing dispatch work in a relatively complete, safe, and refined manner.

2.                      Scheme description

This command and dispatch system integrates various communication methods such as SDH fiber optic transmission, satellite, IP, GSM, and E1, realizing the access of video terminals, fixed telephones, handheld walkie talkies, desktop intercom terminals, mobile phones, and communication vehicles and other voice terminals on the system. Optical fiber communication is the main communication method in the entire system, ensuring sufficient image transmission bandwidth, while wireless links serve as auxiliary transmission methods to achieve wireless terminal access to the dispatch system. It can be compatible with existing military dedicated lines (E1 lines or optical lines), telecommunications fixed line networks, mobile phone terminals, satellite phones, and wireless radio terminals, fully utilizing the multimedia characteristics of the system to meet the comprehensive needs of the military for dispatch services.

The air traffic control command and dispatch center is no longer able to meet the requirements of system command and dispatch through traditional means of audio and video communication. Our company fully utilizes the multimedia integrated audio and video command and dispatch system of Ruiguang to meet the requirements of this system. We plan and design a comprehensive information exchange method based on audio and video transmission, as well as network, text, SMS, fax, etc., to solve the problem of "visible, audible, and manageable" audio and video command and dispatch, achieve precise and efficient command and control of special aircraft work, and provide real-time, accurate, and efficient information technology support for the decision-making of leaders.

This system integrates SDH fiber optic transmission, E1 access, various 64K Z-interfaces (such as telephone interface, radio interface, satellite telephone interface, amplification microphone interface, etc.), as well as IP communication and other access methods, to achieve the transmission and exchange of audio, video, and network. And provide seamlessly connected voice recording voice mailbox servers, network management servers, and fax email sending and receiving servers. At the same time, this system provides centralized network management for the fiber optic transmission equipment connected to it, enabling configuration and status queries for remote devices.

Through the command console of the command center, various types of information are accessed, processed, and output. Existing communication methods, airport video surveillance, air traffic control data display, flight information display, real-time meteorological data, etc. are connected to the command center and displayed on the large screen TV wall. A digital audio, video, and data comprehensive command system is established to achieve integrated, modern, and intelligent command functions such as real-time transmission, monitoring, intercom, and broadcasting of audio and video data around the clock. According to the main functions of the system, it is divided into the following subsystems.

Configure magnetic telephone modules, common telephone modules, programmable telephone modules, etc. on the command and control platform. These functional modules are reused on the PDH panel and connected to the PCM equipment in the wiring room through the optical interface of the PDH panel. These functional modules correspond to existing external dedicated lines, and can also add multiple magnetic, common, and programmable telephone interfaces through the command and dispatch platform.

u                      2.2.2 "One Touch Direct" Telephone System

Touch screen dispatch console and integrated communication system

The command and dispatch platform can set a one key direct function for all calls, which can be pre-set with hotline buttons for direct one key dialing, or can be called by clicking on a member icon on the console touch screen. Through the command and dispatch platform software, telephone users can have two types of icons on the console touch screen: traditional telephone user icons and IP telephone user icons. By clicking on these icons, the console and any telephone user can be directly connected with one click. If the telephone user has installed a command and dispatch terminal, visual intercom with the user can be achieved by clicking on the IP telephone user icon.

One click through has point-to-point communication and can also be grouped for one click through. On the command and dispatch platform, the main combat units are grouped, and several end users are grouped together. When clicking on the group icon, the console can achieve one click through for all users in this group.
