Abstract

This invention discloses a BeiDou communication terminal with an RJ45 network interface, belonging to the field of BeiDou terminal equipment technology. The BeiDou communication terminal includes a BeiDou positioning circuit, a BeiDou communication circuit, a microcontroller processing circuit, a serial-to-RJ45 converter circuit, and a power management circuit. The BeiDou positioning circuit receives BeiDou positioning signals and outputs positioning data. The BeiDou communication circuit receives and transmits BeiDou short message data. The microcontroller processing circuit is connected to the BeiDou positioning circuit, the BeiDou communication circuit, and the serial-to-RJ45 converter circuit, respectively, to parse, group, and forward the positioning data and short message data. The serial-to-RJ45 converter circuit converts serial port data into RJ45 interface data and converts data input from the RJ45 interface back into serial port data. This terminal, while retaining BeiDou positioning and short message communication capabilities, adds an RJ45 network interface, enabling access to shipboard local area networks and improving upon the problems of short transmission distance, insufficient anti-interference capabilities, and limited connectivity with network devices in existing terminals.
