[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] In one embodiment, Figure 1 As shown, a power fault detection system 100 is provided, which includes: a receiver 101, a digital processing module 102, a transceiver controller 103 and a host computer 104; the receiver 101 is connected to the digital processing module 102 for communication; the transceiver controller 103 is connected to the digital processing module 102 and the host computer 104 for communication;

[0038] The receiver 101 is used to obtain the power carrier signal to be processed, sample the power carrier signal, obtain the sampled data of the power carrier signal, and send the sampled data to the digital processing module 102;

[0039] The digital processing module 102 is used to perform digital filtering, synchronous detection and Fourier transform on the sampled data to obtain the channel characteristic information and communication content information of the power carrier signal, and send the channel characteristic information and communication content information to the transceiver controller 103;

[0040] The transceiver controller 103 is used to send the channel characteristic information and the communication content information to the host computer 104;

[0041] The host computer 104 is used to perform fault location and fault detection according to the channel characteristic information and communication content information.

[0042] Specifically, refer to Figure 1 In response to the fault detection instruction for the power carrier system, the power fault detection system 100 obtains the power carrier signal of the power carrier system by the receiver 101, performs signal decoupling, analog front-end processing and analog-to-digital conversion operations on the power carrier signal, obtains the sampling data of the power carrier signal, and sends the sampling data to the digital processing module 102; the digital processing module 102 performs digital filtering, synchronous detection and fast Fourier transform processing on the sampling data to obtain the channel characteristic information and communication content information of the power carrier signal, and transmits the channel characteristic information and communication content information to the transceiver controller 103; the transceiver controller 103 transmits the channel characteristic information and communication content information to the host computer 104; and the host computer 104 performs fault location and fault detection on the power carrier system according to the channel characteristic information and communication content information.

[0043] Among them, signal decoupling refers to filtering out interference signals such as 220V / 50Hz AC on the power line to obtain the carrier signal carrying communication content information; analog front-end processing refers to amplifying, filtering and conditioning the received analog signal to make it suitable for subsequent analog-to-digital conversion and digital signal processing; analog-to-digital conversion operation refers to converting analog signals into digital signals.

[0044] Among them, digital filtering refers to filtering digital signals to remove noise and interference signals; synchronous detection refers to determining the carrier frequency, phase and other parameters of the received signal in order to correctly demodulate the data information; fast Fourier transform processing refers to performing spectral analysis on sampled data to extract channel characteristic information and data information.

[0045] Among them, channel characteristic information includes parameters such as pilot signals and channel responses, which are used to estimate and compensate for channels to improve communication quality; communication content information refers to the communication content actually transmitted, which requires demodulation, decoding and other operations to restore the original communication content.

[0046] For example, by measuring the signal strength of the pilot signal and comparing it with the signal strength under normal circumstances, if the signal strength is significantly reduced, it may indicate that there is signal attenuation or loss, which may be caused by a breakpoint, poor contact or high impedance fault in the power line; by analyzing the signal quality of the pilot signal, such as the signal-to-noise ratio (SNR) or bit error rate (BER), a decrease in signal quality may indicate the presence of interference, increased noise or signal distortion, which may be related to faults in the power line; by sending a series of pilot signals with different frequencies and measuring the response at each frequency; by analyzing the frequency response characteristics, filtering effects or frequency-dependent faults in the power line can be identified. For example, some faults may only affect signals within a specific frequency range.

[0047] In the above-mentioned power fault detection system, the power carrier signal to be processed is first obtained by the receiver 101, the power carrier signal is sampled to obtain the sampling data of the power carrier signal, and then the sampling data is digitally filtered, synchronously detected and fast Fourier transformed by the digital processing module 102 to obtain the channel characteristic information and communication content information of the power carrier signal, and then the received channel characteristic information and communication content information are forwarded to the host computer 104 by the transceiver controller 103. Finally, the host computer 104 performs fault location and fault detection on the power system according to the channel characteristic information and communication content information, so that the fault location and fault detection are performed by extracting and analyzing the channel characteristic information and communication content information of the power carrier signal, which can quickly detect the fault of the power system, improve the fault detection efficiency, and do not need to install additional sensor equipment and reduce costs, which can meet the needs of real-time monitoring of power line networks.

[0048] In one embodiment, the digital processing module 102 is also used to generate an interrupt request signal based on the channel characteristic information and the communication content information, and send the interrupt request signal to the transceiver controller 103; the transceiver controller 103 is also used to parse the interrupt request signal, obtain the channel characteristic information and the communication content information, perform information verification on the channel characteristic information and the communication content information, and send the channel characteristic information and the communication content information to the host computer 104 if the information verification passes.

[0049] Specifically, the digital processing module 102 generates an interrupt request signal according to the channel characteristic information and the communication content information, and sends the interrupt request signal to the transceiver controller 103; the transceiver controller 103 obtains the channel characteristic information and the data information from the digital module according to the interrupt request signal, performs information verification on the channel characteristic information and the communication content information, and when the information verification passes, sends the channel characteristic information and the communication content information to the host computer 104. In this embodiment, after obtaining the channel characteristic information and the data information, the digital processing module 102 sends an interrupt request signal to the transceiver controller 103, and the interrupt request signal is used to request the transceiver controller 103 to copy the channel characteristic information to the storage location of the transceiver controller 103, and the transceiver controller 103 uses the processing power of the chip module, the memory interface, and the data transmission protocol to complete the data copying process.

[0050] It should be noted that when the transceiver controller 103 performs data replication, in order to ensure the consistency of data before and after replication, it is necessary to detect and correct errors during the data replication process through a verification mechanism. In order to ensure the consistency of the storage result and the output result, the above verification result is used as a condition for outputting channel characteristic information such as the pilot signal. When the verification result is consistent, it indicates that the current data meets the consistency and can be output as the channel characteristic information of the power carrier system.

[0051] For example, before data replication, the digital processing module 102 generates a check bit of the data, and transmits the data and the check bit to the transceiver controller 103. After receiving the data, the transceiver controller 103 recalculates the check bit of the data and compares whether the check bits are consistent. When the check bits are consistent, the transceiver controller 103 can output the data to the host computer 104. When the check bits are inconsistent, the transceiver controller 103 does not output the data to the host computer.

[0052] In one embodiment, the channel characteristic information includes a first check bit, and the communication content information includes a second check bit; the transceiver controller 103 is also used to recalculate the check bit according to the channel characteristic information and the communication content information to obtain a third check bit and a fourth check bit, respectively; if the first check bit is the same as the third check bit and the second check bit is the same as the fourth check bit, it is determined that the information verification has passed; otherwise, it is determined that the information verification has not passed.

[0053] Specifically, the transceiver controller 103 may use a data verification mechanism to generate a check bit. The data verification mechanism includes, but is not limited to, a parity check and a cyclic redundancy check. When the first check bit is the same as the third check bit and the second check bit is the same as the fourth check bit, the transceiver controller 103 determines that the data verification is successful; when the first check bit is different from the third check bit, and / or the second check bit is different from the fourth check bit, the transceiver controller 103 determines that the data verification has not passed.

[0054] Among them, successful data verification indicates that no error occurred during the data replication process, and failed data verification indicates that an error occurred during the data replication process.

[0055] In the embodiment of the present application, the transceiver controller 103 determines whether an error occurs during data replication by comparing the first check bit with the third check bit, and the second check bit with the fourth check bit, thereby improving the accuracy of fault detection.

[0056] In one embodiment, Figure 2 As shown, the digital processing module 102 includes a first register and a second register, and the transceiver controller 103 includes a third register and a fourth register; the digital processing module 102 is also used to save the channel characteristic information to the first register, demodulate and decode the communication content information to obtain the original communication content, and save the original communication content to the second register; the digital processing module 102 is also used to send the channel characteristic information in the first register to the third register of the transceiver controller 103, and send the original communication content in the second register to the fourth register of the transceiver controller 103.

[0057] Specifically, refer to Figure 2 The digital processing module 102 saves the channel characteristic information to its own first register, demodulates and decodes the communication content information, obtains the demodulated and decoded original communication content, and saves the original communication content to its own second register. The digital processing module 102 transmits the channel characteristic information in the first register to the third register of the transceiver controller 103, and transmits the demodulated and decoded original communication content in the second register to the fourth register of the transceiver controller 103.

[0058] In this embodiment, data confusion can be avoided by caching channel characteristic information through the first register and the third register, and caching the original communication content after demodulation and decoding through the second register and the fourth register.

[0059] In one embodiment, the receiver 101 is also used to decouple the power carrier signal to obtain a decoupled analog carrier signal, perform analog front-end processing on the analog carrier signal to obtain a target analog signal, perform analog-to-digital conversion on the target analog signal to obtain a target digital signal as sampling data of the power carrier signal.

[0060] Specifically, the receiver 101 includes a capacitor-inductor coupler, an analog front end and an analog-to-digital converter, the analog front end includes an amplifier, a bandpass filter, a low-pass filter and a limiting circuit, the power carrier signal is decoupled by the capacitor-inductor coupler, the decoupled signal is processed by the analog front end in turn through the amplifier, the bandpass filter, the low-pass filter and the limiting circuit to obtain an analog signal, and then the analog signal is passed through the analog-to-digital converter to obtain sampled data. The digital processing module 102 includes a digital filter, a phase-locked loop and a fast Fourier transformer, the sampled data is filtered through the digital filter, the carrier frequency and phase of the received signal are tracked and locked through the phase-locked loop, and the channel characteristic information and data information such as the pilot signal used for channel estimation are separated through the fast Fourier transformer. The transceiver controller 103 is a chip module used to control the reception and transmission of signals. The transceiver controller 103 transmits channel characteristic information and communication content information to the host computer 104, and the host computer 104 performs signal strength analysis, signal quality analysis and frequency response analysis on the signal characteristic information and communication content information, thereby locating and detecting faults in the power carrier system.

[0061] In one embodiment, Figure 3 As shown, a power fault detection method is provided, which is applied to Figure 1 The power fault detection system 100 in FIG. 1 is taken as an example to illustrate, and includes the following steps:

[0062] Step S301 , obtaining a power carrier signal to be processed, sampling the power carrier signal, and obtaining sampling data of the power carrier signal.

[0063] Step S302, digital filtering, synchronous detection and Fourier transform are performed on the sampled data to obtain channel characteristic information and communication content information of the power carrier signal.

[0064] Step S303: perform fault location and fault detection based on the channel characteristic information and communication content information.

[0065] Specifically, the power fault detection system first acquires the power carrier signal to be processed, samples the power carrier signal, and obtains the sampling data of the power carrier signal; then digitally filters, synchronously detects, and Fourier transforms the sampled data to obtain the channel characteristic information and communication content information of the power carrier signal; finally, based on the channel characteristic information and communication content information, fault location and fault detection are performed.

[0066] For specific limitations of the above steps, please refer to the relevant embodiments of the power fault detection system, which will not be described in detail here.

[0067] In the above-mentioned power fault detection method, first, the power carrier signal to be processed is obtained, and the power carrier signal is sampled to obtain the sampling data of the power carrier signal; then the sampled data is digitally filtered, synchronously detected and Fourier transformed to obtain the channel characteristic information and communication content information of the power carrier signal; finally, fault location and fault detection are performed based on the channel characteristic information and communication content information, so that fault location and fault detection are performed by extracting and analyzing the channel characteristic information and communication content information of the power carrier signal, which can quickly detect the fault of the power system, improve the fault detection efficiency, and do not require additional sensor equipment and reduce costs, which can meet the needs of real-time monitoring of power line networks.
