An Infrared Wireless Networking Equipment Applied in Satellite Cabin

Abstract

The invention discloses infrared wireless network equipment applied in a satellite capsule. The infrared wireless network equipment applied in the satellite capsule comprises a satellite host computer and satellite-borne electronic equipment, and further comprises an infrared wireless access point and an infrared wireless terminal. The infrared wireless access point is connected with the satellite host computer, and the infrared wireless terminal is connected with the satellite-borne electronic equipment. The infrared wireless terminal comprises a wired interface module A, an infrared optical antenna A, a slave control module and an infrared control module A. The infrared wireless access point comprises a wired interface module B, an infrared optical antenna B, a host control module and an infrared control module B. According to the infrared wireless network equipment, an infrared wireless optical communication way replaces a traditional satellite bus communication way, traditional communication cables among satellite-borne electronic equipment is eliminated, interconnection among electronic equipment inside a satellite is achieved, complexity of connection through the traditional cables is avoided, electromagnetic interference of wireless radio frequency communication is avoided, and the weight of the satellite is lightened effectively.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an infrared wireless networking device applied in a satellite cabin. Background technique [0002] The traditional intra-satellite communication system mainly conducts interconnection and communication through the on-board bus, and the star host and other on-board electronic devices are connected to the on-board bus through wired interfaces, such as figure 1 shown. This traditional intra-satellite communication system is connected by cables, which has disadvantages such as large volume and weight, poor anti-electromagnetic interference ability, complex network connection and low integration. [0003] The infrared wireless networking technology in the satellite cabin is an emerging technology to realize the internal communication of the satellite. Compared with the digital tube system of traditional in-cabin wire transmission and radio frequency wireless transmission, in-...
