An interference analysis system for electric power wireless private network

Abstract

The embodiment of the invention provides an interference analysis system oriented to a power wireless private network. The system comprises a comprehensive analysis unit and a plurality of electromagnetic interference monitoring devices. Each electromagnetic interference monitoring device collects wireless signals; when the field strength value of the wireless signal exceeds the warning thresholdvalue, the wireless signal is judged to be an interference signal and an early warning signal is generated, and the interference signal and the early warning signal are sent to a comprehensive analysis unit, and the early warning signal comprises early warning information and position information of a first electromagnetic interference monitoring device which sends the early warning signal. The interference identification module identifies the interference type according to the early warning information and the interference signal, and sends the interference type to the interference positioning module. The interference positioning module determines the position of the interference source according to the position information of the first electromagnetic interference monitoring device, theinterference signal and the interference type. By implementing the invention, the interference early warning and positioning of the wireless side of the power network are realized, and the stable operation of the power network is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an interference analysis system oriented to a private electric power wireless network. Background technique [0002] At present, the frequency band used by the power wireless private network is a frequency band shared by multiple industries. Problems such as signal leakage and overlap in adjacent frequency bands will interfere with the stability of the wireless private network and affect the quality of service access.
