Abstract
The invention provides a carrier communication router discovery method. The method comprises the following steps of S1, performing meter reading by a router module; S2, searching an electric meter path, if the electric meter path exists, performing a step S3, and otherwise, performing a step S4; S3, performing electric meter reading task transmission according to the path which is searched in the step S2, performing task finishing judgment in three seconds, judging failure if transmission time exceeds three seconds, and judging success if transmission is finished within three seconds; S4, performing broadcast and executing the meter reading task, and performing task finishing judgment within three seconds; and S5, checking a task finishing judgment result, and if the task is failed, performing cycling.
Description
Technical field
The present invention relates to communication technical field, and in particular to a kind of carrier communication routing discovering method.
Background technology
In recent years, the research for low-voltage powerline carrier communication achieves greater advance, and the technology successfully should
For in the engineering projects such as remote meter reading and Street lamps control.Existing power-line carrier communication system is to complication, intellectuality side
To development, such as a set of intelligence system for integrating illumination, air-conditioning, safety check, fire-fighting both can be used for family, can also be used for
The inside management and control of large enterprise；But existing carrier communication routing discovering method is using simultaneously inconvenience at present, so being badly in need of a kind of
Carrier communication routing discovering method is solving this problem.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, there is provided a kind of carrier communication routing discovering method, the load
Wave communication routing discovering method can solve the above problems well.
To reach above-mentioned requirements, the present invention is adopted the technical scheme that：A kind of carrier communication routing discovering method is provided, should
Carrier communication routing discovering method includes
The carrier communication routing discovering method has the advantage that as follows：The carrier communication routing discovering method operation more facilitate and
Applicability is stronger.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding of the present application, the part of the application is constituted, at this
Same or analogous part, the schematic description and description of the application are represented using identical reference number in a little accompanying drawings
For explaining the application, the improper restriction to the application is not constituted.In the accompanying drawings：
Fig. 1 schematically shows the flow chart of the carrier communication routing discovering method according to the application one embodiment.
Specific embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with drawings and the specific embodiments, to this
Application is described in further detail.
In the following description, the reference to " one embodiment ", " embodiment ", " example ", " example " etc. shows
So the embodiment or example of description can include special characteristic, structure, characteristic, property, element or limit, but not each reality
Applying example or example all necessarily includes special characteristic, structure, characteristic, property, element or limit.In addition, reuse phrase " according to
One embodiment of the application " is not necessarily referring to identical embodiment although it is possible to refer to identical embodiment.
For the sake of simplicity, eliminated well known to a person skilled in the art some technical characteristics in below describing.
According to one embodiment of the application, there is provided a kind of carrier communication routing discovering method, as shown in figure 1, including such as
Lower step：

According to one embodiment of the application, the S4 of the carrier communication routing discovering method also comprises the following steps：
Receive correct task return frame then to succeed, confiscate, fail), correct task is recorded if success and returns to frame terminal address
It is ammeter path, failure is not recorded then, if mission failure is checked meter, but the ammeter has path, is also not required to change ammeter path.
According to one embodiment of the application, the S5 of the carrier communication routing discovering method specifically includes following steps：
If task is completed, path is correct, if mission failure, records the frequency of failure, and the frequency of failure is 1 return S3, failure time
Number 2 then performs S4.
Embodiment described above only represents several embodiments of the invention, and its description is more specific and detailed, but not
It is understood that to be limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, not departing from
On the premise of present inventive concept, various modifications and improvements can be made, these belong to the scope of the present invention.Therefore this hair
Bright protection domain should be defined by the claim.
