Remote Control System Based On Existing Network

With the constant change of the mode of modern war, air combat style also close by the original small to large area long development. Existing ground-to-air communications system can not meet the needs of modern ground-to-air communications command, how to make full use of the existing equipment on the basis of the ground-to-air communications, developing the new system to adapt the complex modern combat become urgent needs to solve the problem.This paper designed a kind of ultrashort wave ground-to-air communications network system, through comprehensive digitalization of modern communication technology, the ethernet-based more remote control command, through radio unified dispatch server center, not only realize the radio remote control and monitoring, and realize the different between radio resource sharing and backup use, at the same time, make full use of the existing communication resources, enhances the reliability of communication and ground-to-air anti-destroying ability, reached the large area of the integration of wireless command.The system consists of bureau, node switches, management software, remote terminal, DuiKongTai and server components, including the inning, node switches and management software are independent research and terminal. System networking, a general adopt tertiary structure of the number of node number, and switches. Several bureau will end by 2 M link exchanges in accordance with the tree topology together again, each node switch nearby access switches. The inning The switch can be used as a network bureau of the administration, the only downward all the relay panels are connected at lower innings switches or nodes switches, Also can be used as a reliever plate, the higher the switches connected up that administration bureau, the relay panels are connected node switches. Lower down System through management software realize the switches connected terminals, games and disconnect control signal, surveillance and so on the function, also can complete information and service record connection. According to the software management terminal sessions given authority to change different client switches in the system of the bureau level, more flexible application of existing communications system. The switch can provide innings and El interface, and between the interfaces of colluding E1, ring back. Node switches can provide 1 road with E1 between 32 time slot in E1, merger, collaboration and loop back, at the same time can extract audio/E1 port of data interface.System is adopted digital cross-connections obstruction, greatly improving the technology of cross any link, reduce the flexibility of digital crossover matrix capacity, not only realizes link cross connection, and is completely blocked the complexity of the reduced control. To meet the needs of business, this system USES a parallel digital switching technology, the voice, data and signaling synchronous exchange connections, and combines various signal.Practical application of remote control system, can effectively to empty voice communications through cross real circuit transmission time PCM, Control and record by IP mode, service, etc, realize the exchange of transmission channels of communication function of digital network air. The real-time and reliability of communication, and to use in actual use good results were obtained.
