Description

TECHNICAL FIELD OF THE INVENTION AND METHOD FOR EFFECTIVE HANDLING OF RF DATA BY DATA ABSTRACT DATA AND THE APPARATUS AND THE APPARATUS THEREOF}

The present invention relates to effective handling of RF data, and more particularly to meta data that abstracts the data of attribute data of a synchronized RF signal, environment data from which the RF signal is captured, and RF data digitizing the RF signal. The present invention relates to a method and apparatus for effectively handling RF data through data abstraction by metadata, which can generate data and transmit, backup and analyze the metadata.

Recently, in order to analyze the characteristics of an RF signal (or EM signal) in the field of RF (Radio Frequency) technology, a research for developing a device capable of capturing and storing the RF signal and improving its function has been conducted. The following describes an apparatus (referred to as an RF black box) that captures and stores the RF signal as a whole without receiving signal conversion such as decoding or tuning after receiving an RF signal of a specific frequency band.

For example, the RF black box can be utilized when capturing, storing and analyzing RF data at the time of RF side field test after chipset design and measuring electric field intensity in a broadcasting station, And can be used for various purposes such as measuring the sensitivity, storing EM signals and medical ultrasound signals directly, analyzing the characteristics of the signals, and coping with them.

However, in order to store the entire RF signal in the RF black box, a large-capacity storage device is required. Therefore, in order to overcome the limitation of the storage capacity as described above, in the past, data was stored in a hard disk drive (HDD), a redundant array of independent disks (RAID), and a storage area network (SAN) connected through a high-speed bus. When moving or back-up is needed to analyze the RF data, a large capacity external hard disk was used or a communication network was used to upload data and download it in a lab environment.

As described above, the RF black box mainly analyzes the spectrum or power of the RF signal to determine whether the environment in which the RF signal is received is unsuitable for receiving the RF signal or is there a failure in the components constituting the receiver or transmitter of the RF signal. In order to provide a function for monitoring the data, the analysis requires a large amount of RF data directly every time, so there is a lot of limitations in mobility and accessibility for analysis.

For example, when moving (delivering) data offline using an external hard disk to handle large sized RF data as described above, there is a risk of time lag or data loss, and data can be stored online using a communication network. In case of moving, not only the storage side needs to prepare a large storage device in advance, but also because the data is large, there is a problem that the transmission speed is delayed by increasing the traffic of the network and the transmission time increases accordingly.

In addition, it is difficult to handle the RF data at a general field engineer level, rather than a professional user, and a user interface for characterizing an RF signal related to a desired time and place without providing direct handling of the RF data is not provided. to be.

The present invention was created to solve the above-mentioned problems, and it is possible to generate metadata abstracted by separating or combining information desired by a user from RF data digitized RF signals, attributes and environment data synchronized thereto.

An object of the present invention is to provide a method and an apparatus for effectively handling RF data.

In addition, the present invention is an abstraction of data by metadata that can be converted and displayed graphically through a user interface by transmitting abstracted metadata by separating or combining information desired by a user from RF data and attribute and environment data synchronized thereto.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of an effective handling method and apparatus of the RF data through the data abstraction by metadata according to the present invention.

The present invention is to enable the analysis of the RF signal using the RF data digitized the RF signal and its attributes and environmental data, generating metadata abstracting the RF data using the attributes and environmental data, The present invention relates to an abstraction apparatus and method for intuitively analyzing the characteristics and reception environment of an RF signal without being limited to the user's location and time by allowing the metadata to be displayed or transmitted and backed up through a user interface. .

In addition, in the present invention, the server 100 includes abstraction means for generating metadata and abstracting RF data, and the client is user-friendly including the abstracted metadata with a predetermined text, graphic, image, or a combination thereof. Converting means and converting means for converting the information into information.

1A and 1B are exemplary views showing the configuration of an apparatus related to data abstraction according to an embodiment of the present invention.

As shown therein, the server 100 includes an abstraction function for generating metadata and abstracting RF data. It is assumed that the attribute data and the environment data are respectively stored in the storage or HDD of the server in synchronization with the RF data. In addition, it is apparent that the server 100 may be provided to virtualize local storage connected to external devices including an RF black box connected to a network including its own local storage and use the same as the local storage of the server itself.

The network may be a general purpose network such as the Internet, or may be connected via direct cabling. When the GaGa device is connected through a direct connection, as in the case of diversity recording, the network latency is a problem, the network environment is difficult to build, or the user's convenience. Obviously, it can be connected via a wireless network such as WIFI.

In addition, the server 100 and the client may be built and used based on software in one PC, notebook, tablet, smart device, or mobile device, and the client may be driven in the form of an app on the mobile device.

The server 100 performing the abstraction function as described above may be configured using an RF black box, or may be configured as an independent device separate from the RF black box, or the server 100 or the RF black box. It may be configured to include a separate abstraction means 101 in the.

As shown in FIG. 1A, the server 100 may be directly connected to at least one external device (eg, RF black box, GPS, instrument, camera, client, storage, database) in a wired / wireless manner, or FIG. As shown in FIG. 1B, the server 100 may be connected to at least one external device through a network such as the Internet. For example, the external device may be a GPS, GIS or navigation device that detects terrain / geographic information, a reference (REF) receiver that extracts A / V data, SNR, BER, a camera that extracts image data, and RF data. It may include a specific device under test (DUT) that outputs signals or information such as SNR, BER, etc. when captured, external instruments that output various measurement information, and an RF black box that captures and stores the RF signal.

The server 100 may store relevant data (eg, RF data and its attributes and environmental data) input from the external device in the storage 200 in real time or non-real time, and the storage may be stored in the server or external. At least one of local storage of the device, storage of a separately configured data server, storage of a networked cloud system, or combinations thereof.

In order to maintain consistency of data related to each other among data output from the server 100 and an external device connected thereto, the local time of each device matches a predetermined reference time (eg, local time of the server, GPS time). It is preferable.

Therefore, the server 100 and the external device connected thereto are equipped with a GPS outputting a reference time, and the absolute time is matched using the GPS time, or, if not, each device (eg, a server) in the server 100. The local time of the external device) can be collectively managed in the form of a table or a database, or the consistency of the relative time that matches the time can be achieved by compensating for the difference between the reference time and each local time. For example, an index (for example, time information) may be added to data transmitted from the external device, and when the server 100 receives the data to which the index is added and stores the data in the storage 200, When the time information included in the index is local time instead of the reference time, time synchronization between the data of the server and the external device is performed by compensating for the difference between the reference time and the local time. Alternatively, the server 100 periodically transmits reference time information to each external device connected thereto so that each external device always matches its local time with the received reference time.

The data stored in the server 100 may include, for example, RF data obtained by capturing an RF signal in an RF black box, feature points extracted from the RF signal or RF data, power (field strength), trigger, spectogram, error, Attribute data, such as an impulse (time), an envelope, a Peak to Average Ratio (PAR), and environmental data, such as geometry, GPS, and a video, which represent the environmental information in which the RF signal is captured.

Spectrum monitoring, packet sniffing for communication channel analysis on a baseband waveform using a modulation toolkit, radio receiver design, RF recording and playback for wireless transceiver verification, validity of DUT, , A digital video broadcast BER test, and a joint time-frequency analysis using a Gabor spectrogram (Joint time-frequency analysis using the Gabor spectrogram). In the case of digital video, it is possible to detect that a person or thing moves slightly between frames as a result of a transmission error.

In this case, the environmental data is detected through an external device connected to the server 100. Therefore, the number of environmental data may be increased or decreased according to the number of external devices connected to the server 100. The RF data may be stored as digital data, and the attribute data and environment data may be expressed in a compressed image, text, binary, or any data format.

Therefore, the server 100 not only maintains consistency of time-correlated data with respect to data detected through several external devices in the same place, but also automatically collects and manages the location from GPS and GIS information. This allows the user to enter place information directly into the manual.

In other words, the server 100 receives RF data extracted from an RF black box, attribute data (eg, power and spectrum) and environmental data extracted from an external device (eg, camera image and broadcast image) and maintains consistency. While storing the data in storage, for example, the server 100 combines the relevant data into a single file (or data) and outputs it as an integrated data stream / file or indexes the relevant data. Create a separate file (e.g. index file, metadata file) or extract specific field information (key value or attribute value required for database configuration) from each data (or their combined data) Thereby maintaining the temporal and temporal coherence of the data. The method of maintaining data consistency of the server 100 has been described above.

Hereinafter, a data abstraction method of the server 100 will be described.

In the present invention, the data abstraction means to abstract the RF data digitized from the RF signal into metadata using attributes and environment data synchronized thereto, that is, the RF data using the attributes and environment data. This means creating metadata that abstracts the.

Here, the metadata is data for data, and may be configured in various formats according to the purpose. For example, only simple indexing information of various data may be collected and configured, and as in the present invention, feature information (data) may be configured to be represented in detail in text or graphics in a specific time domain (or frequency domain). In this case, the metadata may be described using a markup language including Standard Generalized Markup Language (SGML) and Extensible Markup Language (XML) for proper structure and description for displaying the information.

In the present invention, the server 100 may generate various metadata by separating or combining the information stored in the storage 200 according to a condition desired by the user. When the metadata is transmitted to the client and displayed, the metadata may be added, integrated, and synthesized through a user interface. Accordingly, the user can conveniently analyze the information by displaying the information in various forms using the metadata.

In generating and transmitting the metadata, the server 100 generates a metadata abstracted in real time by combining only information (data) of a condition desired by a user and transmits the metadata to a user, or 2) a predetermined random setting. Various types of metadata that abstracts the information organized according to the information combination standard of the user may be generated in advance, and the user may transmit metadata of the desired type among the metadata types.

(Example 1)

First, the method of generating metadata in real time by combining only the information (data) of a condition desired by the user in real time and transmitting the metadata to the user by inputting a condition of the information desired by the user through a user interface on the client side If the request is made, the server 100 generates metadata abstracting the information corresponding to the requested condition and transmits the generated metadata to the client side.

For example, referring to FIG. 2, the user inputs a condition of desired information (data) through the user interface of the client side (S101). When the user requests the metadata by inputting the desired information conditions as described above, the server 100 accesses information corresponding to the input condition from the storage (or a database) (S102). The metadata abstracting the accessed information is generated in real time (S103), and the generated metadata is transmitted to the client side (S104). Accordingly, the client-side user interface (eg, WeiverEx GUI) receives the metadata and converts it to text or graphics for display.

FIG. 3 is an exemplary view for explaining a condition of information requested from a client side and configuration of metadata generated at a server side in FIG. 2.

As shown in the figure, the user interface on the client side may request information stored in the storage (or database) 200 (eg, device ID, measurement time (period), measurement interval, location, and data type). It is configured to be combined or selected according to various conditions. The information on the items to be input under each condition may be input by the user directly or by selecting among sub-items provided in a list form in each item.

In addition, the user interface may include a history of information input when the user requests metadata or a type of metadata (eg, G1, G2, ..., Gn) that may be generated by conditions of the information to be requested. Alternatively, you can store the metadata from the server in sequential order. For example, if a user requests power information of an RF signal detected at an arbitrary location (Location 1) from device ID # 1 from 10:00 to 30:00 on August 20, 2012, the user interface inputs the input. Transmits the information condition and the request command to the server side, and automatically sets the type (or history) of the metadata corresponding to the information of the input condition to an arbitrary name (for example, G1) internally. Save as.

The input condition history or the metadata type stored as described above may be used when requesting or displaying new metadata by adding, integrating, and synthesizing each other in the user interface. When requesting new metadata by adding, integrating, synthesizing with each other as described above, the requested history or new type information (for example, G2) may be arbitrarily set and stored as described above. At this time, the type information (G1 ~ Gn) of the metadata corresponding to the input condition of the information is displayed only for convenience of description and does not necessarily have to display the type information separately.

When metadata is requested by inputting information conditions desired by the user as described above, the server 100 accesses the information (data) corresponding to the condition from the storage (or database) 200 and abstracts the accessed information. Generate metadata.

In this case, the metadata includes index information and detailed information corresponding to the type of data requested by the user. For example, the power information of the RF signal detected at an arbitrary location (Location 1) from the device ID # 1 from 10:00 to 30:00 on August 20, 2012 is included in units of 1 second. On the other hand, the format of the metadata may be configured by sequentially writing all the information in one line (each information may be distinguished by commas or spaces), or may be configured in a table form as illustrated. The present invention is not limited thereto, and may be freely configured in various other formats.

The metadata also includes more detailed information (e.g. frequency, RF input voltage) related to the requested information (e.g. power, PAR, BER, SNR, etc.) and information for display of the metadata (e.g. document structure). And information related to the description, color, font, lines, images, etc.) may be further included.

Next, the server 100 generating metadata of information corresponding to the condition requested by the user transmits the metadata to the client side, and the user interface of the client side parses the metadata, and the contents included in the metadata. Convert and display text or graphics.

4A and 4B are exemplary views illustrating a method of displaying metadata through the user interface in FIG. 2.

As described above, the metadata may be described using any language such as SGML and XML, so that a document having a desired structure can be created, and its detailed format (eg, text, font, color, position, line, image) Etc.) is also possible. Accordingly, the user interface converts and displays the contents included in the metadata according to the structure and format of the document described in the metadata according to a predetermined format.

For example, suppose that the user requests the power information of the RF signal received in a specific time period (for example, from 00.0 seconds to 10.0 seconds) in units of 2 seconds, and the client receives metadata that abstracts the requested information. In this case, the user interface on the client side may convert and display the power information included in the metadata according to the structure and format of the document described in the metadata, as shown in FIG. 4A (a). have. That is, the time axis and the power axis divided by a second time from a specific time (0 second) are displayed, and a line corresponding to the power value every 2 seconds on the time axis is displayed in the form of a graph. In this case, as shown in (b) of FIG. 4A, the same power information may be displayed by requesting metadata having only different measurement periods and intervals. As described above, when the measurement period and the interval are different with respect to the same information (eg, power), many differences may occur in the analysis result. For example, it can be seen that an error is detected in the 6 second section in FIG. 4A (a) and an error is detected in the 3 second section in FIG. 4A (B).

By the way, the user interface may display only one piece of information on one screen, but by requesting metadata about information of at least one or more various conditions, and selectively adding, integrating, or synthesizing the received metadata to display the metadata. It is also possible to analyze the information more intuitively and conveniently.

For example, the metadata type requested under the above conditions (0 second to 2 second power information) is defined as G1 for convenience, and a condition different from the above conditions (for example, power information at 1 second to 2 second intervals) Request new metadata and define the new metadata type as G2 for convenience, and the user interface receives the G1 type of metadata and displays it as shown in FIG. 4A (a) and transmits the G2 type metadata. Assume that the display as shown in Figure 4a (b).

As described above, two types of metadata G1 and G2 are stored in the user interface. If the user instructs the synthesis of metadata of the two types G1 and G2, the user interface (c) of FIG. As shown in FIG. 2, two types of metadata may be synthesized and displayed. In this case, the result of synthesizing the two types of metadata is that the user can obtain the same result as requesting new metadata that abstracts power information from 0 seconds to 1 second.

In this case, the function of synthesizing and displaying the information as described above is not necessarily limited to the same information. As shown in FIG. 4B, metadata for each information may be used even when comparing different information (eg, power, BER). Can be synthesized and displayed. For example, the metadata type requested as the first condition (power information of 0 seconds to 2 seconds) is defined as G1 for convenience, and the second condition different from the condition (for example, BER information of 1 second to 2 seconds) Request new metadata and define the new metadata type as G2 for convenience, and the user interface receives the G1 type metadata and displays them as shown in FIG. 4B (a), and displays the G2 type metadata. Assume that the display is received as shown in (b) of Figure 4b. At this time, if the user instructs the synthesis of the two types of metadata (G1, G2), as shown in (c) of Figure 4b, by synthesizing and displaying the two types of metadata, the user is a screen Will allow you to compare and analyze two pieces of information (eg power, BER) at the same time.

Similarly, when the user instructs addition or integration of at least one or more metadata received from the server, the user interface divides one screen into multiple screens, and then displays the divided screens in each of the divided screens, as shown in FIG. 5. Any one of the additional or integrated metadata may be displayed separately. Alternatively, after displaying multiple frames on one screen, each of the metadata may be displayed on each frame.

In this case, as shown in FIG. 4A and FIG. 4B, the metadata synthesized, added, or integrated as described above may be multi-screen (e.g., conditions for the received metadata by setting only the detailed conditions differently for the same type of data). 1 type of metadata screen, 2 types of metadata screens, 2 types of metadata screens in which condition 1 and condition 2 are combined, or as shown in FIG. It may be. For example, if a user requests metadata for spectrum information, metadata for GPS information, metadata for I / Q signals, metadata for power, and receives each of the requested metadata, the user interface The metadata may be converted into text or graphic form and displayed on the split screen (or frame) designated by the user. In this case, the divided screens (or frames) are not necessarily divided into the same size, and may be displayed in different sizes according to information to be displayed. At this time, the position of each split screen can be changed according to the user's selection.

As described above, the first embodiment generates metadata abstracting information corresponding to the desired condition only when the user wants it, and thus may be a burden when load is concentrated on the server. There is no burden of adding storage capacity by sending it directly to the client side without storing it separately in the storage, and it improves user convenience and information selectivity because metadata is generated by combining only information that meets the user's desired condition. Occurs.

In the present invention, by generating metadata and abstracting the RF data, the rough characteristics of the RF data can be analyzed first by a small amount of metadata, and a row for detailed analysis on the time or frequency region where the indication is detected can be analyzed. raw data may be required. At this time, the large sized raw data can be retrieved from the server, the RF black box, or an external device on the screen. In other words, it is desirable to analyze the RF data of interest through metadata and finally request and analyze the data.

Regarding the reproduction of the RF data of interest, the RF data is converted into an RF signal, upconverted, output through an antenna, and reproduced by a specific receiver, and a specific modulation and demodulation algorithm is applied to the RF data. There is a method that can be played immediately without converting to, and it is obvious that the present invention is not limited to a specific method.

(Example 2)

Next, 2) various types of metadata that abstracts the information organized according to a predetermined information combination standard are generated in advance, and a method of transmitting metadata of a user's desired type among the metadata types abstracts the data. The metadata type to be generated in advance according to an arbitrary information combination criterion, and in advance generates metadata abstracting the combined information (data) according to each type (for example, G1, G2, G3) and the storage 200 After storing in the user, when a user requests any one of the pre-generated metadata types, the metadata of the requested type is transmitted.

For example, as shown in FIG. 6, the method of generating metadata in advance according to the predetermined information combination criterion, and transmitting the metadata of the type selected by the user, is performed through the client side user interface. When the user requests the metadata type previously generated by the server 100 (S201), the server transmits the metadata type (eg, G1, G2, and G3) generated in advance to the client side through the user interface. Display (S202), and when the user selects one of the metadata types (e.g., G1) (S203), the server transmits the metadata of the selected type (S204), thereby allowing the client-side user interface to It receives metadata and converts it into text or graphics and displays it.

Here, the information combination criteria for defining the type of metadata may be an example of network bandwidth or cost that each data occupies when transmitting data through a communication network, and n types (eg, G1, G2) according to the criteria. Metadata can be generated by separating, G3, ..., Gn). In this case, the information combination criteria defining the type, the number of types classified according to the information combination criteria, and the configuration of information (data) to be combined for each type can be variously configured.

As described above, the second embodiment requires additional storage of the previously generated metadata types, and thus the storage capacity must be added, and only one metadata can be selected from the previously created metadata types. As a result, user convenience and information selectivity may be deteriorated. However, since various types of metadata may be generated in advance by using a time zone with a low server load, there is an advantage of not burdening the server side.

As described above, the abstraction methods described through the above embodiments may be appropriately selected in consideration of the advantages and disadvantages according to the application situation or purpose.

As described above, the present invention receives the abstracted metadata using the RF data and its attributes and environment data, and enables the RF signal to be analyzed in various ways through operations such as addition, synthesis, and integration in the user interface.

Therefore, it is not necessary to additionally transmit large RF data (or larger A / V data among environmental data), but if RF data is additionally transmitted through the network at the request of the user, the RF data is Because it takes up a lot of bandwidth and requires a lot of cost and transmission time, according to the situation and cost of the communication network, only part of the RF data is transmitted, and the rest is transmitted during off-peak time (when a relatively low traffic occurs). It is also possible to improve the efficiency of network usage.

In addition, the present invention can connect a multi-network communication network having a different bandwidth for the transmission of RF data or metadata abstracting it as described above, when a wide bandwidth and inexpensive communication network is not available, relatively small bandwidth and high cost Expensive mobile networks (e.g. 3G, 4G) transmit only small data, such as metadata, and large data, such as RF data, later when a wider, cheaper network is activated. It is possible. It is also possible to transfer and store files using the mobile cloud server. In addition, the user interface may further display information received from the interworking interface device (eg, Remote UI and Weiver Tracer) for providing a remote function or local information for convenience.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point. Accordingly, the technical scope of the present invention should be defined by the following claims.
