Description

Technical Field

[0001] The present invention relates to the technical field of intangible cultural heritage, and in particular to an intangible cultural heritage detection system. Background Art

[0002] Intangible cultural heritage (abbreviated as "ICH") is a cultural concept covering many aspects. It mainly refers to various traditional cultural expressions and cultural spaces that are closely related to the lives of the masses and have been passed down from generation to generation by people of all ethnic groups. ICH is unique and embodies the cultural spirit of a specific nation or group. At the same time, it is also fragile and can be easily impacted by the process of modernization and lose its living conditions. In addition, ICH is still alive and needs to rely on the existence of inheritors to continue. Finally, it is inherited and must be passed down from generation to generation to maintain its vitality. In order to effectively protect ICH, governments and international organizations have taken a variety of measures. This includes conducting a census to record ICH projects, establishing a representative list system to identify important projects, strengthening research, preservation and dissemination to promote the inheritance and development of ICH, and playing a leading role in the government and mobilizing all sectors of society to participate in protection work.

[0003] The intangible cultural heritage detection system plays an important role in the protection and management of intangible cultural heritage. The system can record various information of intangible cultural heritage in detail, including inheritors, skill processes, cultural background, folk activities, etc., digitize the collected data, and establish a database for long-term preservation and retrieval.

[0004] However, in the existing intangible cultural heritage detection system, the system relies on input data. If the quality control in the data collection process is not in place, it may lead to inaccurate or incomplete records, which may easily affect the accuracy and completeness of the data. In the process of data collection, if the personal information and cultural activity details of the inheritors are not encrypted for protection, the system may face the risk of data loss or malicious tampering. It is necessary to strengthen data security measures. Therefore, these problems can be gradually overcome and the overall effect and efficiency of the intangible cultural heritage detection system can be improved. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides an intangible cultural heritage detection system, which has the advantages of classifying, organizing and saving the original data corresponding to the analysis data and related information through the intangible cultural heritage database, and then encrypting and saving the internal data of the database through a data encryption module. The internal data of the database can be obtained only after the fingerprint information and face recognition information of the authorized personnel are successfully confirmed. When the intangible cultural heritage detection early warning module receives the corresponding abnormal signal, it will issue an early warning according to the corresponding signal and feed back the early warning signal to the relevant personnel. The quantity processing module uniformly processes various types of data information, retains the uniqueness of various types of data, avoids repeated collection that affects the accuracy and integrity of the data, and solves the above-mentioned problems of the intangible cultural heritage detection system.

Start calculation, N means calculation ends until the last data in the data set, that is End, [N] 2 Represents the square value of all data points in the acquisition interval. The square values ​​of all data points in the acquisition interval are added together to calculate the cleaned video feature SPtz; The video difference SPc calculation formula is as follows: SPc=SJjl-SPtz The video difference SPc is calculated by subtracting the video feature SPtz from the current intangible cultural heritage video record SJjl.

5. The intangible cultural heritage detection system according to claim 4, characterized in that: The calculation formula of the cleaned text feature WBtz is as follows: In the formula, Where i=1 means starting the calculation from the first data in the real-time text data set, that is Start calculation, N means calculation ends until the last data in the data set, that is End, [N] 2 Represents the square value of all data points in the collection interval. The square values ​​of all data points in the collection interval are added together to calculate the cleaned text feature WBtz; The text difference WBc calculation formula is as follows: WBc=WBjl-WBtz In the formula, the text difference WBc is calculated based on the current text record WBjl minus the text feature WBtz.

6. The intangible cultural heritage detection system according to claim 5, characterized in that: The calculation formula of the image feature TPtz is as follows: In the formula, Where i=1 means starting the calculation from the first data in the real-time image dataset, i.e. Start calculation, N means calculation ends until the last data in the data set, that is End, [N] 2 Represents the square value of all data points in the collection interval. The square values ​​of all data points in the collection interval are added together to calculate the cleaned image feature TPtz; The picture difference TPc is calculated as follows: TPc=TPjl-TPtz In the formula, the picture difference TPc is calculated based on the current picture record TPjl minus the picture feature TPtz.

7. The intangible cultural heritage detection system according to claim 6, characterized in that: The calculation formula of the personal login set BRDL is as follows: BRDL=[ZWxx=0, RLSBxx=1] In the formula, ZWxx represents the fingerprint information of the authorized person, RLSBxx represents the face recognition information of the authorized person, ZWxx=0 represents that the fingerprint information of the authorized person is successfully matched, RLSBxx=1 represents that the face recognition matching of the authorized person is successful, and the encryption module sends the matching success signal to the intangible cultural heritage detection and early warning module to obtain data.

8. The intangible cultural heritage detection system according to claim 7, characterized in that: When the audio difference YPc becomes negative, it represents a decrease in the public's interest in oral history audio, traditional music, and dialects, languages, and pronunciations in the intangible cultural heritage. The data analysis module sends an audio data warning signal to the intangible cultural heritage detection and warning module, and feeds back the audio data warning signal to relevant personnel.

9. The intangible cultural heritage detection system according to claim 8, characterized in that: When the video difference SPc becomes a negative number, it means that the performance and inheritance of dance in the intangible cultural heritage has decreased. The data analysis module sends a video data warning signal to the intangible cultural heritage detection and warning module, and feeds back the video data warning signal to relevant personnel.

10. The intangible cultural heritage detection system according to claim 9, characterized in that: When the text difference WBc appears a negative number, it means that the inheritance and preservation of text materials have decreased. The data analysis module sends a text data warning signal to the intangible cultural heritage detection and warning module, and feeds back the text data warning signal to relevant personnel. When the picture difference TPc appears a negative number, it means that the preservation and inheritance of traditional patterns, handicrafts atlases or traditional paintings are facing threats. The data analysis module sends a picture data warning signal to the intangible cultural heritage detection and warning module, and feeds back the picture data warning signal to relevant personnel.
