Problems solved by technology

[0007] (1) With the rapid development of smart grid, the measurement of electric energy has developed a lot. The communication used in the existing electric energy measurement mainly adopts RS485, micro-power wireless, GPRS wireless and power line carrier, etc., but the development of wireless-based electric energy measurement is relatively slow.
[0008] (2) It is impossible to realize the restricted management of harmonic users in the power grid to reduce the harmonics injected into the power grid

Embodiment 1

[0038] An embodiment of the present disclosure provides an electric energy metering system based on wireless communication.

[0039] Such as figure 1 The shown electric energy metering system based on wireless communication includes hardware units and software units;

[0040] Among them, the hardware unit includes an acquisition layer and a gateway layer; the acquisition layer includes two parts: an information acquisition module and a transmission module, and the acquisition module is used to unify the electric energy and transfer it to the transmission module of relevant information; the transmission module communicates through wireless communication (such as Zi gbee) to transmit information, the gateway layer itself cannot directly transmit information, it needs to realize the transmission through information conversion;

[0041] The software unit includes the management layer and the power collection layer; the design is implemented through the peripheral circuit using th...

Embodiment 2

[0051] The embodiment of the present disclosure introduces a method for measuring electric energy based on wireless communication.

[0052] Such as image 3 The shown electric energy metering method based on wireless communication is based on the electric energy metering system based on wireless communication introduced in Embodiment 1, and includes the following steps:

[0053] Step S01: The acquisition layer enters the initial state by using the event round-robin mechanism, automatically switches to the low-power mode, and the acquisition layer is automatically awakened when an event occurs; if multiple event distortions occur at the same time, each event is judged according to the priority of the event and Process one by one;

[0054] Step S02: The gateway layer is connected to the transceiver of the controller and the physical interface through Ethernet, and at the same time completes the effective matching of the PHY and the MAC; selects the event distortion with high si...

Embodiment 3

[0096] Embodiment 3 of the present disclosure provides a computer-readable storage medium.

[0097] A computer-readable storage medium, on which a program is stored, and when the program is executed by a processor, the steps in the method for measuring electric energy based on wireless communication as described in Embodiment 2 of the present disclosure are implemented.

[0098] The detailed steps are the same as the wireless communication-based electric energy metering method provided in the second embodiment, and will not be repeated here.

Abstract

The invention provides an electric energy metering system and method based on wireless communication, and the method comprises the following steps: enabling a collection layer to enter an initial state through employing an event round robin mechanism, automatically switching a low-power-consumption mode, and enabling the collection layer to be automatically awakened during an event; if a plurality of events are distorted at the same time, judging each event according to the priority of the events and processing the events one by one; connecting the gateway layer to the controller and the transceiver of the physical interface through the Ethernet, and completing effective matching of the PHY and the MAC at the same time; selecting event distortion with high similarity to construct an event distortion point local structure operator, and completing accurate matching between event distortion points; finding out event distortion point pairs meeting reference point conditions through a propagation algorithm, and continuing accurate matching in a local area by using a new reference point pair; gradually spreading from a local area to the whole image in a matching range, and completing global-level matching.
