Description

Technical Field

[0001] The present invention relates to the technical field of substation equipment, and in particular to a method and system for standardizing and collecting voiceprint data based on substation equipment. Background Art

[0002] At present, researchers in the electrical field have achieved fruitful research results in the non-stop detection of main power grid equipment according to actual production needs, which has promoted the continuous improvement of the detection technology level and formed a new multi-in-one detection pattern of electrical, chemical, optical, vibration and acoustics. At the same time, new methods for equipment status evaluation and diagnosis based on non-stop detection are emerging in an endless stream. Through on-site measurements and subsequent evaluation and diagnosis, many latent defects of equipment have been discovered, effectively avoiding the occurrence of many faults. With the widespread application of artificial intelligence technology in intelligent power operation and inspection, defect detection based on vision (image, infrared, ultraviolet imaging) has been initially used in practice. However, the use of visual signals alone for fault diagnosis is too single, and the image acquisition device itself has high requirements for the use environment and acquisition conditions.

[0003] The research progress of voiceprint non-stop detection technology for substation equipment has been made, but the existing substation equipment is of various types and models, and the operating environment is different, so it is difficult to unify the voiceprint collection method, resulting in different formats of the original collected voiceprint data and different meanings. In addition, due to the large differences in the collection methods of different voiceprint devices, it is impossible to standardize the collection of voiceprint data, which seriously affects the quality of voiceprint data and cannot form effective equipment fault detection results based on voiceprint monitoring. Summary of the invention

[0004] The present invention provides a standardized voiceprint data collection method based on substation equipment. The method expands the data sources and means of defect detection to improve the robustness of operation and inspection, and performs non-stop power detection of substation equipment based on voiceprint signals, enriching the data sources and effectively improving the operation and maintenance efficiency of substation equipment.

[0018] Configure the field name, byte length, and sampling rate as the file header, write the PCM raw audio data into the voiceprint data file, and save it as an audio file in WAV format.

[0019] It should be further explained that the server parses and extracts the TCP transmission data structure of the voiceprint data to determine whether the file header meets the preset conditions;

[0020] If the file header does not meet the preset conditions, the server will send a collection control instruction to the voiceprint collection device based on the MQTT protocol; and obtain the voiceprint data again for analysis, extraction and judgment processing;

[0021] Until the file header meets the preset conditions, the PCM original audio data is written into the voiceprint data file.

[0022] It should be further explained that, in the method, the server obtains the ID information and IP information of the voiceprint collection device through the MQTT protocol, and receives the voiceprint data in the form of a message; the message adopts the JSON encoding format.

[0023] It should be further explained that the server sends a collection control instruction to multiple voiceprint collection devices based on the MQTT protocol, and configures the ID information and IP information of the voiceprint collection device in the collection control instruction;

[0024] After receiving the collection control instruction, the voiceprint collection device parses and extracts the ID information and IP information;

[0025] Determine whether the parsed ID information and IP information match its own information;

[0026] If there is a match, the voiceprint data of the substation equipment will be collected;

[0027] If they do not match, the server will be fed back with an error message of the acquisition control instruction.

[0028] It should be further explained that the voiceprint collection device configures the ID information and IP information into the voiceprint data, and the server parses the ID information and IP information in the voiceprint data and matches them to the corresponding voiceprint collection device.

[0045] It should be understood that Figure 1 The number of voiceprint collection devices, networks and servers in the embodiment is only for illustration. According to the implementation requirements, there may be any number of voiceprint collection devices, networks and servers. For example, the server may be a server cluster composed of multiple servers.

[0046] A voiceprint collection device is a device that can automatically perform numerical calculations and / or information processing according to pre-set or stored instructions. Its hardware includes but is not limited to microprocessors, application-specific integrated circuits (ASICs), programmable gate arrays (FPGAs), digital signal processors (DSPs), embedded devices, etc.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1 The figure is a flow chart of a method for standardizing the collection of voiceprint data based on a substation in a specific embodiment, the method comprising:

[0049] S11, the voiceprint collection device establishes an MQTT connection with the server;

[0050] S12, the server sends a collection control instruction to the voiceprint collection device based on the MQTT protocol;

[0051] MQTT (Message Queue Telemetry Transport) is a message protocol based on the publish / subscribe paradigm under the ISO standard (ISO / IEC PRF 20922). It is a publish / subscribe message protocol designed for remote devices with low hardware performance and poor network conditions.

[0052] The voiceprint collection device of the present invention establishes a communication connection with the server based on the MQTT protocol and sends control instructions, which can meet the needs of data communication in various network situations and ensure the timeliness of obtaining the voiceprint data of the substation equipment.

[0053] S13: The voiceprint collection device receives the collection control instruction, collects the voiceprint data of the substation equipment, processes the voiceprint data, and sends it to the server;

[0054] S14: The server analyzes the voiceprint data transmitted by the voiceprint collection device to extract the original audio data;

[0055] S15: The server sends a stop command based on the MQTT protocol, and the voiceprint collection device stops collecting voiceprint data, disconnects the communication connection, and terminates the transmission of voiceprint data.

[0056] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0057] In one embodiment of the present invention, based on the standardized voiceprint data collection method of the substation equipment, a possible embodiment will be given below to illustrate its specific implementation scheme in a non-limiting manner.

[0058] S21, the voiceprint collection device establishes an MQTT connection with the server;

[0059] S22, the server sends a collection control instruction to the voiceprint collection device based on the MQTT protocol;

[0060] S23: The voiceprint collection device receives the collection control instruction, collects the voiceprint data of the substation equipment, processes the voiceprint data, and sends it to the server;

[0061] In the embodiment of the present invention, after receiving the collection control instruction, the voiceprint collection device establishes a TCP connection with the server;

[0062] The voiceprint collection device sends the voiceprint data to the server via the TCP protocol.

[0063] It is understandable that by establishing an MQTT connection between the voiceprint collection device and the server, the server can obtain the ID and IP information of the device and realize the control of the collected voiceprint data. For the voiceprint collection device to transmit voiceprint data to the server, the TCP transmission control protocol is used. TCP (TCP, Transmission Control Protocol) is a transmission protocol specially designed to provide a reliable end-to-end byte stream on an unreliable Internet network.

[0064] S24: The server parses the voiceprint data transmitted based on the TCP transmission control protocol and extracts the original audio data; here, the server can accept the standard format data transmitted by the acquisition device, parse it and save it into a WAV format audio file.

[0065] S25: The server sends a stop command based on the MQTT protocol, and the voiceprint collection device stops collecting voiceprint data, disconnects the communication connection, and terminates the transmission of voiceprint data.

[0066] In this way, the present invention can collect voiceprint data of substation equipment in a standardized manner, making it convenient for monitoring personnel to receive and review it, and effectively improving the efficiency of voiceprint data collection of substation equipment. It can also efficiently collect, store, and process voiceprint data, and can implement process monitoring based on the status of substation equipment and the status of the power grid, using multi-dimensional space to describe the entire voiceprint data status. Improve the quality and efficiency of workpiece processing, timely discover and issue early warnings on quality and safety hazards in workpiece processing, improve the management level and efficiency of substation equipment, and control the risks of power grid operation, thereby achieving the timeliness and scientificity of the whole process collection, management, and control of voiceprint data of substation equipment.

[0067] Further, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for standardizing and collecting voiceprint data based on substation equipment is provided, and the method includes:

[0068] Step 1: Establish an MQTT connection between the voiceprint collection device and the server, where the voiceprint collection device is the MQTT client and the server is the MQTT server. The voiceprint server can obtain the ID and IP information of the device through the MQTT protocol, and remotely control the voiceprint device to collect voiceprint data by sending messages. The message adopts the JSON encoding format, and the sending data format is shown in Table 1.

[0069] Table 1 shows the data format sent by MQTT

[0070]

[0071] Step 2: The server sends a control command based on the MQTT protocol, and the voiceprint collection device starts collecting voiceprint data. When the voiceprint collection device receives the start command, it establishes a TCP connection with the server. The voiceprint device is a TCP client, and the server is a TCP server.

[0072] Step 3: After the voiceprint collection device establishes a TCP connection with the server, it starts to collect the voiceprint data of the substation equipment, processes it, and transmits it in a standard data structure, as shown in Table 2.

[0073] Table 2 TCP transmission data structure

[0074]

[0075] Step 4: The server parses the data transmitted by the voiceprint collection device and extracts information such as voiceprint sampling rate, bit depth, channel, PCM original audio data, etc. The channel information, sampling bit number, sampling rate and other information are added as the file header, the PCM data is directly written into the file, and saved as an audio file in WAV format.

[0076] Step 5: The server sends a stop command based on the MQTT protocol, and the voiceprint collection device stops collecting voiceprint data, disconnects the TCP connection, and terminates the transmission of voiceprint data.

[0077] The present invention realizes remote control and data transmission of the voiceprint collection device based on the MQTT protocol and the TCP protocol, adopts a standard data structure to transmit the voiceprint data, and saves it as an audio file in WAV format on the server. The standard voiceprint data collection method is uniformly adopted for different substation equipment, which effectively solves the technical difficulties in data collection and analysis in different scenarios, different substation equipment, and different operating states. It is of great significance to the development of non-stop detection technology for main power grid equipment and the establishment of related systems, and effectively improves the efficiency of substation operation and maintenance.

[0078] Based on the above embodiments, the server of the present invention parses and extracts the TCP transmission data structure of the voiceprint data, and determines whether the file header meets the preset conditions;

[0079] If the preset conditions are met, the server considers that the TCP transmission data structure meets the monitoring requirements, that is, meets the collection standards.

[0080] The preset condition here is that the TCP transmission data structure for receiving voiceprint data has the data information involved in Table 2, that is, it has field name, byte length, sampling rate, bit depth and channel information, but is not limited to these and can be expanded as needed.

[0081] If the file header does not meet the preset conditions, it may be due to a communication failure, or an abnormality in the collection process of the voiceprint collection device, or an abnormality in the processing of the collected voiceprint data by the voiceprint collection device, resulting in the voiceprint data being abnormal and failing to meet the preset conditions, which will affect the server's use of the voiceprint data.

[0082] That is to say, if the file header does not meet the preset conditions, the server will send a collection control instruction to the voiceprint collection device based on the MQTT protocol; and obtain the voiceprint data again for parsing, extraction and judgment processing;

[0083] Until the file header meets the preset conditions, the PCM original audio data is written into the voiceprint data file.

[0084] In the above method of the present invention, in order to improve the monitoring efficiency and standardize the voiceprint data in the unified system, the server sends a collection control instruction to multiple voiceprint collection devices based on the MQTT protocol, and configures the ID information and IP information of the voiceprint collection device in the collection control instruction;

[0085] After receiving the collection control instruction, the voiceprint collection device parses and extracts the ID information and IP information;

[0086] Determine whether the parsed ID information and IP information match its own information;

[0087] If there is a match, the voiceprint data of the substation equipment will be collected;

[0088] If there is no match, the collection control instruction error information will be fed back to the server. The mismatch indicates that the collection control instruction received by the voiceprint collection device is not for the voiceprint collection device, and the error exception is fed back to the server. The server can re-match to the corresponding voiceprint collection device to avoid affecting the voiceprint data collection and monitoring of the substation equipment.

[0089] In an embodiment of the present invention, the voiceprint collection device configures the ID information and the IP information into the voiceprint data, and the server parses the ID information and the IP information in the voiceprint data and matches them to the corresponding voiceprint collection device.

[0090] The server binds the ID information and IP information of the voiceprint collection device with the corresponding substation location information, and the voiceprint collection device configures the substation location information into the voiceprint data, so that the server can match the corresponding substation after parsing and extracting the original audio data.
