Abstract

The invention discloses an aircraft electrical system communication terminal. The terminal comprises a master node terminal and a plurality of slave node terminals; an electronic device is selected from an aircraft electronic system to install a master node terminal, and slave node terminals are installed on other electronic devices; the master node terminal and the slave node terminals can achieve automatic networking, and each slave node terminal communicates with the master node terminal through a 28V direct-current power supply line. According to the invention, data communication based onthe power line is realized, so the complexity of a cable network is reduced, and the weight and the volume of the aircraft are reduced.

Description

technical field [0001] The invention relates to a communication terminal of an aircraft electrical system, which belongs to the field of remote measurement systems. Background technique [0002] The communication between electrical equipment in the aircraft generally uses wired methods for data transmission. Due to the large number of electrical equipment and the complex types of communication signals, there is a huge cable network between equipment in the electrical system, which greatly increases the weight and volume of the aircraft. . Contents of the invention [0003] The technical solution of the present invention is to overcome the deficiencies of the prior art and provide a communication terminal for the electrical system of an aircraft to realize data communication based on power lines, thereby reducing the complexity of the cable network and reducing the weight and volume of the aircraft. [0004] Technical solution of the present invention is: [0005] An airc...
