Further, in steps S1 to S5, the near field communication module preferably employs a bluetooth module, and the remote communication module preferably employs an HPLC module.
According to the embodiments, the working principle of the networking mode of the electric energy meter microgrid with complementary and shared remote communication disclosed by the patent application is explained as follows.
Specifically, a microgrid is formed by a plurality of electric energy meters, each electric energy meter in the microgrid has near field communication capability (is equipped with a near field communication module, such as a bluetooth module), and can perform near field communication with each other, that is, local communication among the electric energy meters in the microgrid is realized.
Specifically, each electric energy meter in the microgrid only needs at least one electric energy meter to have a remote communication capability (the electric energy meters respectively have a remote communication module, such as an HPLC module), and the remote communication of each electric energy meter can be realized by means of the near-field communication capability of each electric energy meter, so that data can be uploaded.
It is worth mentioning that if one or more electric energy meters (excluding the extreme condition of all the electric energy meters) in the microgrid originally having the remote communication capability lose the remote communication capability, each electric energy meter in the microgrid still can realize the remote communication.
That is to say, inside the microgrid, when a certain electric energy meter generates a telecommunication demand, the telecommunication demand is preferably satisfied through the telecommunication module of the electric energy meter. When the electric energy meter cannot meet the remote communication requirement (for example, a remote communication module of the electric energy meter is damaged, or the electric energy meter is not configured with a remote communication module), the electric energy meter automatically searches for adjacent electric energy meters through the self-carried near-field communication module, judges whether the electric energy meters have the remote communication capacity (the electric energy meters are configured with the remote communication module and are not damaged) until any electric energy meter is confirmed to have the remote communication capacity, and transmits the information to be transmitted of the original electric energy meter to a remote receiver instead.
It should be noted that the working principle described in the above natural paragraph refers to one-time bridging forwarding, which is also a relatively common application scenario, but not all application scenarios. That is, when the telecommunication requirement of any one electric energy meter cannot be met by the electric energy meter itself, an available electric energy meter is searched only within the coverage range of the near field communication module of the electric energy meter and is replaced by forwarding.
In fact, considering that the topological structure of the microgrid is complex, neither electric energy meter nor other electric energy meters are in a local (neighborhood) relationship with each other, that is, the communication range of the near-field communication capability of neither electric energy meter can cover the other electric energy meters of the microgrid.
For example, in the case of multiple bridging, inside the microgrid, when a certain electric energy meter generates a telecommunication requirement and the telecommunication capability of the certain electric energy meter is lost, the adjacent electric energy meters are automatically searched, and whether the electric energy meters have the telecommunication capability (the telecommunication module is configured and is not damaged) is determined. When all the other electric energy meters in the neighborhood range of the electric energy meter are confirmed to fail to forward the information to be forwarded, secondary bridging is started, the information to be forwarded is transferred to the electric energy meter (a farther electric energy meter, for example, the neighborhood electric energy meter of any electric energy meter in the neighborhood range of the original electric energy meter, and the electric energy meter can be selected through a preset screening method, for example, the electric energy meter with the highest intensity of the bluetooth communication signal) through the near field communication module, the electric energy meter (namely, the electric energy meter receiving the information to be forwarded) repeats the steps until any electric energy meter is confirmed to have the remote communication capability, and the information to be forwarded of the original electric energy meter is forwarded to a receiving party located at a far end (or the steps are finished until all the electric energy meters traversing the microgrid fail to forward the information to be forwarded, for example, all the electric energy meters originally having the remote communication capability of all the electric energy meters of the microgrid lose the remote communication capability, and the microgrid has an extreme condition).
It should be noted that technical features such as specific types of electric energy meters related to the present invention patent application should be regarded as the prior art, specific structures, operating principles, control manners and spatial arrangement manners of the technical features should be selected conventionally in the field, and should not be regarded as the points of the present invention patent, and the present invention patent is not further specifically described in detail.
It will be apparent to those skilled in the art that modifications and equivalents may be made in the embodiments and/or portions thereof without departing from the spirit and scope of the present invention.
