Abstract

The invention relates to a self-contained iridium satellite data multipath transmission terminal device. The traditional device is relatively complex and can not realize the local storage recording of transmission data. The self-contained iridium satellite data multipath transmission terminal device comprises a power module, a core processing module, a four-path serial data interface, an iridium satellite serial interface, an SD (Secure Digital) card storage module, a real-time clock (RTC) module, an iridium SBD9522B module and a satellite antenna. In the invention, the iridium SBD9522B module is used as a main communication module, an STM32F103 chip is used as a main control processor, four paths of transparent data interfaces in the RS232C standard can be provided outwards, a user can directly transmit data to the serial interfaces in the communication Baud rate of 19200 pbs, and the SBD command configuration of the iridium module is not required. The self-contained iridium satellite data multipath transmission terminal device is provided with the four paths of serial data interfaces, so that four paths of transparent serial data transmission can be provided, and meanwhile, the self-contained iridium satellite data multipath transmission terminal device has the function of retransmitting erroneous data, and the reliability of data transmission is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to an iridium satellite data transmission terminal device with data self-storage capability and four-way serial data interface. Background technique [0002] Iridium satellite communication is a wide range of communication methods with global coverage. Compared with other communication methods, it is not restricted by unstable factors such as weather, altitude, ionosphere, distance, etc., and can guarantee data communication anywhere. Signal strength, has a very wide range of applicable occasions, especially suitable for remote and undeveloped areas such as oceans, mountains, deserts, isolated islands, glaciers, and polar regions, where communications are underdeveloped. Exploration, marine environment monitoring, disaster monitoring and forecasting, maritime emergency rescue, ship safety alarm system, emergency rescue and disaster relief, emergency handling, emergency ...
