Problems solved by technology
[0002] In practical applications, power signal communication fails due to different temperature, different number of network nodes, different field wiring, different amount of external environmental interference, mining and other reasons.
Existing test benches or test fixtures can only complete the detection of whether the power line communication is successful, and cannot simulate the on-site power line signal relay situation, nor can it judge the quality of the power line carrier signal, cannot judge the number of relay stages, and cannot simulate the power line signal attenuation, unable to complete a comprehensive performance test

Embodiment 1
[0027] see figure 1 , a power carrier signal quality detection device, including: an electrical source that inputs current to the power line and provides an operating voltage; and, N signal quality detectors connected to the power line, and the N signal quality detectors are lowered to the next-level signal quality detector Send a coaxial signal, and if the signal quality detector obtains the coaxial signal sent by the upper-level signal quality detector, it will generate signal quality information; the first-level signal quality detector among the N signal quality detectors obtains power from the power line The carrier signal is converted into a coaxial signal; N signal quality detectors generate M signal quality information according to the coaxial signal, and M is greater than or equal to 0 and less than or equal to N; signal quality information to generate the maximum number of hops.
[0028] From figure 1 We can see that the coaxial signal converted by the first signal ...
