Abstract

The invention discloses a satellite communication vehicle-mounted module control unit. The satellite communication vehicle-mounted module control unit comprises a first hardware interface group connected with a vehicle-mounted unit and used for realizing information interaction between a control unit and the vehicle-mounted unit; a second hardware interface group connected with a vehicle-mounted host and used for realizing information between the control unit and the vehicle-mounted host; a software interface group connected with the first hardware interface group and the second hardware interface group and used for realizing the information interaction between the first hardware interface group and the second hardware interface group, wherein the software interface group realizes protocoldata transmission by adopting a PPP protocol. In the control unit, by arranging the first hardware interface group connected with the vehicle-mounted unit and the second hardware interface group connected with the vehicle-mounted host in the vehicle-mounted module, the data and protocol conversion between the first hardware interface group and the second hardware interface group is realized by arranging the software interface, thereby better perfecting a communication problem between the vehicle-mounted module and the vehicle-mounted host.

Description

technical field [0001] The invention relates to the communication field, in particular to a satellite communication vehicle-mounted module control unit, a vehicle-mounted module and a vehicle-mounted system terminal. Background technique [0002] The current satellite communication system is mainly composed of the space segment, the ground segment and the system terminal, and the main forms of the system terminal are: hand-held type, portable type, data acquisition type and vehicle-mounted type. The vehicle-mounted module is the core module of the vehicle-mounted terminal. Support functions such as voice, data, short message service and positioning. [0003] Since the vehicle-mounted host is mainly based on the USB interface and the network port, the existing vehicle-mounted module cannot directly communicate with the vehicle-mounted host or vehicle-mounted equipment due to the incompatibility of the hardware interface with the vehicle-mounted host and the differences in sof...
