The information fusion unit includes a collaborative management unit, fault diagnosis unit, information judgment unit, information reasoning unit, information fusion unit, and perceptual learning unit; multiple signal output terminals of the multi-source heterogeneous sensor node model are respectively connected with collaborative management unit, fault diagnosis unit, information judgment unit, information The signal input terminals of the reasoning unit, information fusion unit and perceptual learning unit are connected, and the signal output terminals of the collaborative management unit, fault diagnosis unit, information judgment unit, information reasoning unit, information fusion unit and perceptual learning unit are respectively connected with multi-source heterogeneous information Collaborative decision-making unit connection. The present invention realizes the functions of power equipment operation state monitoring, fault diagnosis and analysis, and intelligent auxiliary decision-making through the combination and coordination of various units of information fusion.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of distribution network equipment, in particular to a multi-sensor and multi-parameter distribution network collaborative monitoring system based on a wireless sensor network. Background technique [0002] The Internet of Things technology is currently triggering a new round of industrial revolution on a global scale and has become an important force to promote economic and social development. A typical IoT system is generally divided into three layers: perception layer, network layer and application layer. Among them, a large number of sensing devices form a perception layer network, which is defined as a wireless ad hoc sensor network. A wireless sensor network (Wireless Sensor Network, WSN) is a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner to cooperatively perceive, collect, process and transmit the information...

AI Technical Summary

Problems solved by technology

[0006] (1) Insufficient online monitoring means for distribution network equipment, lack of equipment operation status information, and distribution network scheduling is in a "blind adjustment" state;

[0007] (2) Insufficient investment in distribution network and weak supporting communication network foundation;

[0008] (3) There are many power distribution equipment, many points and a wide range, and the cost of traditional monitoring and communication methods is huge

[0009] Due to the large number of distribution network equipment and the unbalanced ratio between maintenance personnel and equipment, the maintenance workload is increasing. Excessive maintenance workload has become one of the factors that restrict the growth of power system benefits and work efficiency.

Due to the lack of necessary technical means to support the distribution network condition maintenance work, it is difficult to complete the work in time with limited personnel, which reduces the operation reliability and service level of the distribution network
