Abstract

The invention discloses a test system and a test method for power distribution and utilization communication. The test system comprises a client; a server terminal which comprises a first server unit and a second server unit which are not connected with each other; the second server unit is in radio signal connection with the client; the first server unit is in wired electric signal connection with the client; the carrier communication power line is used for connecting the client and the server terminal, and the carrier communication power line can load an interference source to introduce noise; according to the method, whether the change degree of an index on a carrier communication power line is greater than a preset value is judged through PLC equipment; the delay time of the test system can be obtained by comparing the first time when the first server unit receives the feedback information with the second time when the second server unit receives the feedback information. Therefore, the test process of the test system is more accurate and effective, and the delay time and the intensity of index fluctuation can be obtained.

Description

technical field [0001] The present application relates to the technical field of power distribution communication testing, in particular to a testing system and a testing method for power distribution communication. Background technique [0002] Power carrier communication is PLC, which is the abbreviation of English Power line Communication. Power carrier is a unique communication method of power system. Power carrier communication refers to the technology of high-speed transmission of analog or digital signals through the carrier mode by using the existing power line. The biggest feature is that there is no need to re-establish the network, as long as there are wires, data transmission can be carried out. [0003] Power line carrier communication is divided into low-voltage power line carrier and high-voltage power line carrier according to the frequency bandwidth. In the low-voltage power line carrier data transmission system, the low-voltage power line communicates wit...
