The test of the adaptability mainly tests the communication success rate of the routing scheme in different cell areas. In order to test various types of regions, three representative types of regions are selected for testing, and the test result represents the capability of the routing algorithm to adapt to various types of regions to a certain extent. Referring to fig. 2, fig. 2 is a schematic flow chart of an embodiment of a test for adaptive capacity of a relay path of a power line according to the present application, in the embodiment, the test for adaptive capacity of the relay path of the power line includes the following steps:
s210, selecting a representative type of station area G1 to access a power carrier test platform, sending a carrier signal to a router by a carrier signal sending device, and transmitting the carrier signal to a carrier signal receiving device to form a communication channel;
s220, the upper computer introduces a routing algorithm to the router through a software system, transmits carrier signals on a communication channel for multiple times, counts the times of successful communication, calculates the success rate of communication, and returns an obtained test result to the upper computer;
s230, switching the station areas G2 of the representative types and repeating the step S220;
s240, switching the station area G3 of the representative type and repeating the step S220;
and S250, integrating the test results of the three transformer areas by the upper computer and generating a report.
The real-time communication test mainly tests the quality of a path found by a routing algorithm, if the channel quality of the found path is good and the relay stage number is low, the delay is short, and conversely, the delay is long. Referring to fig. 3, fig. 3 is a schematic flowchart illustrating an embodiment of a method for testing the real-time performance of the communication of the relay path of the power line according to the present application, in which the testing of the real-time performance of the communication of the relay path of the power line includes the following steps:

and S360, the upper computer updates the new routing algorithm, and the steps S310 to S350 are repeated to finally obtain the performance of each routing algorithm.

s450, the upper computer updates a new routing algorithm, and the steps S410 to S440 are repeated.
When the relay selection of the carrier communication path is performed, the load balance of each node in the network needs to be maintained, because the channel quality is easily reduced due to an excessive load, the communication effect is affected, and in a serious case, communication failure is also caused.
When the relay test of the power line carrier communication path is carried out, the characteristics of strong noise resistance and high communication success rate of power frequency communication are utilized to assist the search of the power line relay path, and a power line relay path search algorithm based on power frequency communication is adopted.
