Embodiment Construction

[0030] Further description will be given below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementation cases described here are only used to explain the present invention, and are not intended to limit the invention.

[0031] Such as figure 1 As shown, multiple sensor nodes adopt Zigbee cellular network. Zigbee is a two-way wireless communication technology with short distance, low complexity, low power consumption, low data rate, and low cost. It is mainly suitable for the fields of automatic control and remote control. Zigbee can automatically form a cellular network. The present invention adopts the Zigbee module based on CC2530 chip. Each sensor node is connected to a CC2530 sensor module, and each node has an independent ID code, and communicates with each other through a custom protocol. Each sensor node defines its own node function through a specific identification code.

Abstract

The present invention discloses an internet-of-things-based distributed power supply state monitoring device. The device of the invention comprises a front-end acquisition unit and a background monitoring terminal. The front-end acquisition unit is used for acquiring the working state of a distributed power supply and the meteorological environment information. The background terminal is used forrecording the acquired data of the front-end acquisition unit in real time, monitoring the state of the distributed power supply and evaluating the full life cycle of the distributed power supply in combination with the electrical monitoring data of the distributed power supply and the equipment ledger data of the distributed power supply. Through learning and training the training data set of thedistributed power supply, the health state of the distributed power supply is evaluated, and the fault of the distributed power supply is pre-judged. Based on the technology of the internet of things, the effective technical support means is provided for the friendly grid connection and the reliable operation of the distributed power supply.

Description

technical field [0001] The invention relates to the technical field of distributed power supply state monitoring, in particular to a distributed power supply state monitoring device and method based on the Internet of Things. Background technique [0002] Solar energy is the most accessible clean energy. In recent years, with the increasingly serious environmental problems and the policy support of the Chinese government, the proportion of distributed photovoltaic power generation in the power system is increasing. Photovoltaic power generation can use flat spaces such as Gobi, mountainous areas, and residential building roofs to lay photovoltaic solar panels for power generation, which is convenient and fast. Large-scale distributed power sources are also increasing. [0003] However, the problem of grid-connected distributed photovoltaics has become increasingly prominent. First of all, distributed photovoltaic equipment is affected by factors such as surface dust, ambi...
