Figure 1 As shown, the intelligent fusion terminal system includes: an intelligent fusion terminal 10; the intelligent fusion terminal 10 is connected to the phasor measurement module 20 and / or the artificial intelligence module 30 through a functional interface 40.

[0062] The intelligent fusion terminal 10 is used to identify whether the access module connected to the function interface 40 is the phasor measurement module 20 or the artificial intelligence module 30, and after establishing communication with the access module, cooperate with the access module to perform corresponding functions; the phasor measurement module 20 is used to perform phasor measurement of the three-phase AC power signal input by the intelligent fusion terminal 10 based on the satellite synchronization clock signal, and feed back the phasor measurement results to the intelligent fusion terminal 10; the artificial intelligence module 30 is used to encode and decode the received audio and video data, and feed back the encoding and decoding results to the intelligent fusion terminal 10.

[0063] Among them, the intelligent fusion terminal system is a system that includes an intelligent fusion terminal and other functional modules connected to the intelligent fusion terminal. The intelligent fusion terminal is an intelligent terminal that integrates the functions of power consumption information collection in distribution stations, equipment status monitoring and communication networking, local analysis and decision-making, master station communication and collaborative computing. The access modules of the intelligent fusion terminal include: phasor measurement module and / or artificial intelligence module. The phasor measurement module (PMU) is mainly a phasor measurement unit that uses GPS second pulses as a synchronous clock, which can be used to measure the voltage vector of each node in the power system during transient processes. The artificial intelligence module is an independent module with the function of encoding and decoding audio and video data.

[0064] In this embodiment, the phasor measurement module and the artificial intelligence module can access the intelligent fusion terminal through the functional interface set on the intelligent fusion terminal, and the cooperation between the intelligent fusion terminal and the access module executes the corresponding functions of the access module. The intelligent fusion terminal is aimed at the application scenarios where the power grid system needs to measure the electrical characteristic data such as the contact voltage vector, current vector, power, frequency, harmonics, and interharmonics in real time and accurately at the distributed photovoltaic 10kV grid connection point, 10kV ring network cabinet, and new energy gathering area. The phasor measurement module is connected and communication is established with the phasor measurement module. The phasor measurement module performs phasor measurement on the three-phase AC power signal input by the intelligent fusion terminal based on the satellite synchronous clock signal, and feeds back the phasor measurement results to the intelligent fusion terminal, so that the intelligent fusion terminal can have the phasor measurement function.

[0065] The intelligent fusion terminal is connected to the artificial intelligence module and establishes communication with the artificial intelligence module for application scenarios such as photovoltaic power stations, substations, and distribution stations, where transmission line channels require video monitoring, current operating personnel safety monitoring, personnel safety monitoring in substations, and status detection of smart devices. The artificial intelligence module encodes and decodes the received audio and video data, and feeds the encoding and decoding results back to the intelligent fusion terminal, so that the intelligent fusion terminal can have audio and video encoding and decoding processing functions.

[0066] In an alternative embodiment, Figure 2 This is a structural diagram of the first module access method of the intelligent converged terminal system. Figure 2 As shown, the intelligent fusion terminal 10 is connected to the phasor measurement module 20 or the artificial intelligence module 30 through the same functional interface 40.

[0088] The access signal is a signal generated by the access module when accessing the functional interface. The access module may include: a phasor measurement module and / or an artificial intelligence module. The level state of the access signal may include: a high level and a low level.

[0089] Specifically, the access module is connected to the intelligent fusion terminal through the functional interface. When the intelligent fusion terminal detects the access signal of the functional interface, it indicates that there is an access module connected to the intelligent fusion terminal. At this time, the intelligent fusion terminal judges the level status of the access signal to identify the access module.

[0095] Specifically, when the access module is a phasor measurement module, the intelligent fusion terminal performs handshake communication with the phasor measurement module, so that the phasor measurement module is successfully connected to the intelligent fusion terminal.

If the handshake communication is successful, the satellite synchronization clock signal and the three-phase AC power signal are sent to the phasor measurement module, so that the phasor measurement module performs phasor measurement on the three-phase AC power signal based on the satellite synchronization clock signal to obtain a phasor measurement result.

[0105] Among them, the satellite synchronization clock signal can be understood as the pulse information of seconds (1PPS), minutes (1PPM), hours (1PPH) and other pulses that are highly synchronized with UTC time and output based on the GPS system as the time reference, as well as the standard Beijing time hour, minute, second, Gregorian calendar year, month and day information. It can also be used to achieve the measurement of power frequency quantities and output date, time, frequency clock and power frequency quantity information in the corresponding format through the serial port.

[0106] Specifically, if the handshake communication between the intelligent fusion terminal and the phasor measurement module is successful, it means that the phasor measurement module is successfully connected to the intelligent fusion terminal. The intelligent fusion terminal sends a satellite synchronization clock signal and a three-phase AC power signal to the phasor measurement module, and the phasor measurement module receives the satellite synchronization clock signal for the three-phase AC power signal, and performs phasor measurement on the three-phase AC power signal based on the satellite synchronization clock signal to obtain a phasor measurement result.

[0107] In an optional embodiment, the phasor measurement module performs phasor measurement on the three-phase AC power signal based on the satellite synchronization clock signal, and the steps of obtaining the phasor measurement result include: the phasor measurement module filters the three-phase AC power signal through the analog-to-digital conversion module and obtains a three-phase digital electrical signal based on synchronous sampling of the satellite synchronization clock signal; performs synchronous discrete Fourier transform on the three-phase digital electrical signal based on the synchronous satellite synchronization clock signal to obtain a three-phase phasor; performs phasor measurement on the three-phase phasor to obtain a phasor measurement result.

[0108] Exemplarily, the phasor measurement module monitors harmonics and interharmonics in real time to perform voltage and current vector measurements. When the power measurement and power quality of the terminal body such as voltage deviation and frequency deviation fail, the required power data can be retrieved from the PMU module. The voltage, current frequency, amplitude, and phase of the power supply system change dynamically, and the diffusion of harmonic energy to adjacent spectra will cause measurement errors. The phasor measurement module can use a grouping algorithm model to realize harmonic component measurement to improve measurement accuracy. The sampling rate dynamically tracks the fundamental frequency, and the FFT frequency resolution is 5Hz. Figure 8 This is a schematic diagram of the grouping of harmonic subgroups and interharmonic center subgroups. Figure 8 The interharmonic center subgroup algorithm model shown measures the harmonic current and voltage components to obtain:

[0109]

[0110] Among them, Y isg,h is the root mean square value of the hth harmonic subgroup; sg,h is the hth harmonic subgroup, Y C,(N×h) is the current or voltage spectrum component, N is the total number of harmonics; (N×h)+k is the order of the spectrum component.

[0111] The voltage and current signals of the AC power system can be represented by phasors, which consist of two parts, namely the amplitude X (effective value) and the phase angle φ, which are represented by the real part and the imaginary part in rectangular coordinates. The phase angle of the synchronized phasor is referenced by a high-precision satellite synchronized clock. Fig. 9 is a phase angle diagram of an AC signal, such as Fig. 9 As shown, the synchronous phasor measurement definition is: for AC signals When the maximum value of v(t) occurs at the second pulse, the phase angle is 0 degrees, and when the positive zero crossing point is synchronized with the second pulse, the phase angle is -90 degrees.

[0112] Fig.10 It is a schematic diagram of the phasor measurement process of the phasor measurement module, such as Fig.10As shown in the figure, the phasor measurement module completes phasor acquisition through analog low-pass filtering, synchronous clock sampling, ADC, DFT calculation, and digital filtering. The phasor measurement module uses dynamic phasor fast software algorithm to calculate the amplitude, phase angle of AC voltage, AC current, sequence component, and frequency and frequency change rate of the channel, with high measurement accuracy and fast dynamic response performance.

[0113] S340. Obtain the phasor measurement result sent by the phasor measurement module.

[0114] Specifically, after the phasor measurement module obtains the phasor measurement result, the intelligent fusion terminal may obtain the phasor measurement result sent by the phasor measurement module through an active acquisition method such as polling or a passive acquisition method.

[0115] S350: When the access module is an artificial intelligence module, perform handshake communication with the artificial intelligence module.

[0116] S360: If the handshake communication is successful, wait to receive the encoding and decoding processing result sent by the artificial intelligence module; the artificial intelligence module encodes and decodes the audio and video data to obtain the encoding and decoding processing result.

[0117] For example, the AI ​​module can encode and decode videos with a resolution of 8192x8192, a maximum bit rate of 100Mbps, support for encoding of any number of regions of interest (ROIs), and support for multiple bit rate control modes such as CBR / VBR / AVBR / FIXQP / QPMAP. The AI ​​module can also implement multi-protocol voice encoding and decoding through software, supporting audio encoding formats such as G.711 / G.726 / ADPCM.

[0118] In an optional embodiment, the step of the artificial intelligence module encoding and decoding the audio and video data to obtain the encoding and decoding results includes: the artificial intelligence module encodes and decodes the audio and video data through a well-trained neural network model to obtain the encoding and decoding results.

[0119] Specifically, the AI ​​module can be built based on the new generation of high-performance AI chips from Zhixin Microelectronics, supporting 4K@60 frames H.265 video encoding and decoding capabilities, supporting 4Tops@int8 AI computing power, and supporting the neural network models commonly used in the industry.

[0120] Optionally, before the artificial intelligence module encodes and decodes the audio and video data through a trained neural network model, it also includes: preprocessing the image data in the audio and video data; the preprocessing includes: at least one of overexposure suppression, background light compensation, image enhancement, image shadow correction and image denoising.

[0121] S370: If the handshake communication between the intelligent converged terminal and the access module fails, return to the step of identifying the access module according to the level state of the access signal.

[0122] In this embodiment, if the handshake communication between the intelligent converged terminal and the access module fails, it is necessary to return to S310 to perform the step of identifying the access module according to the level state of the access signal, and try to perform handshake communication with the access module again;

[0123] S380: If the number of handshake communication failures between the intelligent converged terminal and the access module reaches a preset number, the access module is powered on and reset, and the process returns to the step of identifying the access module according to the level status of the access signal.

[0124] In this embodiment, if the number of handshake communication failures between the intelligent fusion terminal and the access module reaches a preset number, after the access module is powered on and reset, the process returns to the step of identifying the access module according to the level status of the access signal, and retries to handshake communication with the access module until the handshake is successful or manual intervention occurs.

[0125] The technical solution of the embodiment of the present invention is as follows: when an access signal of a functional interface is detected, an access module is identified according to the level state of the access signal; when the access module is a phasor measurement module, handshake communication is performed with the phasor measurement module; if the handshake communication is successful, a satellite synchronization clock signal and a three-phase AC power signal are sent to the phasor measurement module, so that the phasor measurement module performs phasor measurement on the three-phase AC power signal based on the satellite synchronization clock signal to obtain a phasor measurement result; the phasor measurement result sent by the phasor measurement module is obtained; if the handshake communication between the intelligent fusion terminal and the access module fails, the step of identifying the access module according to the level state of the access signal is re-executed; when the access module is In the case of an artificial intelligence module, a handshake communication is performed with the artificial intelligence module. If the handshake communication is successful, the encoding and decoding processing result sent by the artificial intelligence module is received; the artificial intelligence module encodes and decodes the audio and video data to obtain the encoding and decoding processing result; if the number of handshake communication failures between the intelligent fusion terminal and the access module reaches a preset number, the access module is powered on and reset, and then the step of identifying the access module according to the level state of the access signal is returned to execute, which can realize flexible access and identification of phasor measurement modules and / or artificial intelligence modules based on different application scenarios, so that the intelligent fusion device can adapt to the needs of phasor measurement and audio and video processing, and enrich the functions of the intelligent fusion terminal.
