The beneficial effect that the utility model reaches: it is relative to other communication channel detection mode, it possesses power line carrier, PLC function, can independently disturb power line, and can real-time storage spectrum information, with the obvious advantage in anti-interference, multiband and accuracy, there is higher economy, reliability and practicality simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of power line carrier communication Channel Detection device, comprises the peripheral assembly such as USB 2.0 OTG, SD read-write, TFT liquid crystal touch screen, coupling filter circuit, STM32 main control unit, power carrier processing unit and 220V power line.
In embodiment 1, by this device access power line, insert in 220v power receptacle by plug, turn on the power switch and can measure, measurement data is stored in USB flash disk or SD card according to time sequencing with certain form, and file type is Excel form.In this example by selecting different capacitance-resistance collocation to realize power utilization environment test targetedly, optimal power supply processing scheme can be selected for electrical appliance by the spectral characteristic of more different electrical appliance when Different periods uses.
In example 2, get the power line that 2 these devices access diverse location respectively, turn on the power switch, one of them is selected, and power communication sending function is double to be measured, another is selected, and receiving function is double to be measured, be stored in USB flash disk or SD card according to time sequencing with certain form by data, file type is Excel form simultaneously.In this example, the frequency spectrum of channel is measured in the change realizing frequency by changing the data of power line carrier communication simultaneously, again in conjunction with the interfering data of electrical appliance to channel, just can filter out best communication channel, thus improve for power communication data basis is provided.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
