Embodiment Construction

[0021] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0022] see figure 1 with figure 2 , this embodiment provides a power line broadband communication signal attenuation method, the method is:

[0023] S1. Divide a power line broadband communication signal into two parallel power line broadband communication signals;

[0024] S2. Process a part of the power line broadband communication signals to allow current to pass through and pass low frequency signals to block high frequency signals;

[0025] S3. Perform signal attenuation processing on another part of the power line broadband communication signal;

[0026] S4. Finally, couple the processed two parts of the signal to a power line;

[0027] The above steps S2 and S3 are carried out simultaneously. that is, if figure 2 As shown, t...

Abstract

The invention discloses a power line wideband communication signal attenuation method which comprises the steps. S1, a power line wideband communication signal is divided into two power line wideband communication signals which are connected in parallel; S2, a part of a power line wideband communication signal allows current to pass and is processed by a low-frequency signal high-frequency signal resistance signal; S3, the other part of the power line wideband communication signal conducts signal attenuation processing; S4, a signal which passes in a step S2 and the signal which passes in a step 3 are coupled together, and the step S2 and the step S3 are simultaneously conducted. When a power line is ensured to be normally galvanized, the power line wideband communication signal can be attenuated, current is stable, electrical equipment in a whole experiment network works stably, and the unnecessary problem that environment can not be really simulated due to abnormal power supply is avoided.

Description

technical field [0001] The invention relates to the field of attenuators, in particular to a power line broadband communication signal attenuation method. Background technique [0002] In the experimental network of simulating power line communication, it is usually necessary to simulate the attenuation of the on-site power line broadband carrier communication signal to simulate the long-distance transmission of the communication signal. power supply, causing some unnecessary problems during the simulation. Contents of the invention [0003] The invention aims to solve the problem that in the experimental network of the simulated power line communication, the power line broadband communication can attenuate the broadband carrier signal on the power line while ensuring the normal energization of the power line. [0004] The present invention provides a power line broadband communication signal attenuation method, the method is: [0005] S1. Divide a power line broadband c...
