General vehicle satellite communication system and general vehicle satellite communication method

Abstract

The present invention discloses a general vehicle satellite communication system and a general vehicle satellite communication method. The system comprises a satellite transceiver subsystem, a service access subsystem, a service processing subsystem, an integrated control subsystem, a power supply subsystem, and a vehicle carrier subsystem. The satellite transceiver subsystem is used for pointing to a communication satellite in satellite communication so as to receive and transmit radio frequency information, and has a frequency conversion function that can realize conversion between intermediate frequency information and radio frequency information, wherein a frequency interface is fixed. The service processing subsystem is in butt joint with the satellite transceiver subsystem and is used for processing received and transmitted satellite signals. The service access subsystem is used for building an internal IP network, providing IP interfaces of all subsystems internally, providing various data interfaces externally and performing IP processing. The integrated control subsystem is used for configuring parameters of all subsystems, and displaying and monitoring the system state. The power supply subsystem is used for providing power for all subsystems in the vehicle. The vehicle carrier subsystem is used as a trunk of a car station.

Description

technical field [0001] The invention relates to satellite communication design, in particular to a general-purpose vehicle-mounted satellite communication system, which can be used in multiple fields such as communication, measurement and control, and the like. Background technique [0002] In the field of satellite communication, due to different application scenarios, different satellite communication methods are required, which involve different satellite communication terminals, very small-scale applications such as satellite communication telephones, and very large-scale applications such as ground microwave communication stations and so on. With the expansion of the application field of satellite communication, in order to better serve the needs of emergency communication and temporary command in public areas such as the government, it is necessary to develop a vehicle-mounted satellite communication system, which is highly mobile and can arrive in time according to mis...

AI Technical Summary

Problems solved by technology

However, the system design has the following defects: 1. The system integration is low, and all module interfaces are inconsistent, resulting in poor system upgrade and expansion capabilities; 2. The system has a single communication method and no communication backup; 3. The system needs to be redesigned for each communication application Start the design, the reusability of the system is poor
