Description

Technical Field

[0001] The present invention relates to the technical field of electric power grid, and in particular to a method and system for handling faults based on HPLC and HRF dual-mode communications. Background Art

[0002] High speed power line communication (HPLC) is a broadband power line carrier technology for data transmission on low voltage power lines. The power line carrier communication network uses power lines as a communication medium to realize the aggregation, transmission and interaction of power consumption information of low voltage power users. Compared with the traditional low speed narrowband power line carrier technology, HPLC technology has a large bandwidth and high transmission rate, which can meet the higher requirements of low voltage power line carrier communication. High speed wireless communication (HRF) uses wireless channels as communication medium, which is not affected by various non-ideal factors of power lines, heavy load and strong noise interference of power grids. The dual-mode power consumption information network integrates high speed power carrier communication and high speed wireless communication, uses power lines or wireless channels as transmission media, connects central coordinator (CCO), proxy coordinator (PCO), and terminal station (STA) and other devices to form a communication network. In recent years, with the development of smart grids, local communication modules based on HPLC and HRF dual modes have been applied on a large scale.

If the communication mode at the time of the failure is the HPLC communication mode, detect whether there is a backup device in the HRF communication mode at the fault node. If so, start the backup device to establish HRF communication for transmission and determine it as the second transmission path; if not, execute step S4; S3. If the communication mode at the time of the failure is the HRF communication mode, detect whether there is a backup device in the HPLC communication mode at the fault node, and if so, start the backup device to establish HPLC communication for transmission, and determine it as the second transmission path; If not, execute step S4; S4, according to the communication data of the faulty node and the preset first rule, searching for a second target node capable of establishing an HRF communication connection, and confirming a second transmission path, including: Acquire a second target node, wherein the distance between the second target node and a normal node on the first communication transmission path is less than or equal to the distance between the faulty node and the normal node on the first communication transmission path; According to the acquired second target node and the preset first rule, scheduling the acquired second target node according to the communication data of the faulty node includes: Prioritizing the communication data of the faulty node to obtain a first priority queue; Analyze the communication data status of the faulty node in sequence according to the first priority queue; If a single second target node can satisfy the communication data of the faulty node, the similarity is calculated according to the second rule, and the first scheduling target node is found for scheduling, and the scheduling is successful; If a single second target node cannot satisfy the communication data of the faulty node, the second priority queue of the second target node is calculated according to the third rule, and the second scheduling target node is searched for according to the second priority queue for scheduling. If the scheduling is successful, the process terminates. If the scheduling is unsuccessful, the process returns to the first priority queue for a loop. Detection module: detects and obtains the cause of the failure of the first communication transmission path according to a preset detection rule; Elimination module: Eliminate the fault according to the cause of the fault; Reset module: After troubleshooting, reset the first communication transmission path to restore normal communication.
