Abstract

The invention discloses an air-ground communication system based on multilink selection. The air-ground communication system comprises a link control module. The input end of the link control module is connected with an interface module and an Ethernet module, and the output end of the link control module is connected with an external network through a network switching module and a protocol conversion module in sequence. The input end of the Ethernet module is connected with an internal network. The air-ground communication system further comprises a power module supplying power to all the modules in the system. According to the air-ground communication system, more communication modes and link selection modes can be provided for air-ground communication access, and the air-ground communication system has the link interface protocol conversion function and the dynamic link expanding supporting function.

Description

A kind of air-ground communications systems selected based on multilink
Technical field
The present invention relates to a kind of air-ground communications systems selected based on multilink.
Background technology
At present, along with the development of Aerobiz and the opening in more spatial domains, in order to solve the day by day frequent broadband air-ground dialogue application problem used, there is more communication link in a large amount of uses of aviation aircraft.
Prior art generally adopts a kind of communication link (as satellite communication) mode, mainly there is following problem:
If 1 has multiple communication links, existing product then cannot carry out link selection and management.
2, existing product cannot carry out link protocol conversion, cannot access ground network when carrying out air-ground dialogue.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of air-ground communications systems selected based on multilink.
The present invention for achieving the above object, adopt following technical scheme: a kind of air-ground communications systems selected based on multilink, comprise link control module, its input is connected with interface module and ethernet module respectively, and its output is connected with external network by network exchange module and protocol conversion module successively; Wherein, the input of described ethernet module is connected with internal network; Also comprise for module each in system provides the power module of power supply.
Beneficial effect of the present invention: air-ground communications systems of the present invention can provide more communication pattern and link selection mode for air-ground dialogue access; It has the function of LI(link interface) protocol conversion, and supports the function of dynamic link expansion.
Accompanying drawing explanation
Fig. 1 is principle of work and power schematic diagram of the present invention.
Embodiment
Shown in Fig. 1, relate to a kind of air-ground communications systems selected based on multilink, comprise link control module, its input is connected with interface module and ethernet module respectively, and its output is connected with external network by network exchange module and protocol conversion module successively; Wherein, the input of described ethernet module is connected with internal network; In addition, also comprise in this system for module each in system provides the power module of power supply.
Within the system, link control module is used for carrying out control treatment to the link between inner and peripheral link, and network data forwarding etc.
Protocol conversion module is used for protocol processes, Interface Controller protocol conversion etc. to different communication link, is connected with internal network by switch; When using multiple protocol conversion module, the corresponding outside Ground-to-air Communication Link of each protocol conversion module.
Network exchange module is used for carrying out exchanges data to Ethernet, thus Dynamic link library external communication link (all based on Ethernet interface).
Ethernet module is responsible for external data to be converted to inner Ethernet data, and provides the communication etc. of internal network, and interface processing module is responsible for equipment I/O and equipment debugging, software upgrading etc.
Power module is responsible for airborne power supply to be converted to internal electric source, and the power supply for other modules inputs.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
