Integrated device merging power line carrier communication and fault detection positioning functions

Abstract

The invention discloses an integrated device merging power line carrier communication and fault detection positioning functions. The integrated device comprises a fault detection carrier signal generation and separation subsystem, a DA module, an AD module, a conditioning circuit, an isolation coupler, a wireless communication module and a power management module at an integrated transmitting end; and further comprises the fault detection carrier signal generation and separation subsystem, the AD module, the conditioning circuit, the isolation coupler, the wireless communication module and the power management module at an integrated receiving end. The integrated transmitting end enables the a carrier signal to possess the fault detection capacity while in the transmission by producing a periodical merging spreading code and a merging modulation code, and comprehensively considers the fault occurring location, and transmits the fault information by using two technologies of the power line carrier communication and the wireless communication, thereby realizing the all-in-one of the electric energy conveying, the data transmission and the fault diagnosis. The reliability and the maintainability of the electric energy conveying and the communication system are improved, and the multifunctional, miniaturized and low-cost design of the detection device is realized.

Description

technical field [0001] The invention relates to an integrated device and method that integrates functions of power line carrier communication and fault detection and positioning, and belongs to the technical field of carrier communication. Background technique [0002] In aerospace and vehicle systems, in order to ensure the high reliability of the system, it is necessary to monitor and detect multiple parts of the entire system. Due to hundreds of measurement parameters, a large number of sensors and actuators are required, correspondingly requiring a large number of data transmission lines; at the same time, the reliance on engine control and transportation management systems is increasing, and the The increase in the use of service and entertainment systems inevitably leads to a large number of cables in aerospace and vehicle delivery systems, heavy weight, and complex distribution and crossing, which reduces the delivery efficiency. In order to solve this situation, Powe...
