In the process of vocal music learning, most of the learning is through the traditional learning mode, that is, learning knowledge in class. For vocal music lovers who want to learn vocal music knowledge, vocal music learning has many requirements on the arrangement of learning place, time and personnel. The purpose of this paper is to develop and design an intelligent training system for vocal music. The flow of audio fingerprint extraction algorithm based on wavelet transform is to transform audio signals into spectrograms. Then, according to the characteristics that wavelet transform can better represent picture information in both time domain and frequency domain, wavelet transform is used for a series of processing of spectrograms. Finally, a more compact fingerprint is obtained by dimension reduction algorithm. This paper applies this algorithm to vocal intelligent training system for the first time. When the humming quality is high, the detection rate can reach more than 90%.

With the rapid development of information technology, mobile internet technology and the increasing popularity of intelligent terminals, the digital, networked, virtualized and mobile information age is quietly changing the way people get information, and digital museums have emerged. VR (Virtual Reality) technology is to use computer simulation to generate a three-dimensional virtual world, providing users with the simulation of visual, auditory and tactile senses. The user can observe things in three-dimensional space in time and without restriction. Traditional museum exhibition is facing the impact of new media technology, which can no longer meet the increasing demand of the audience for museums. Based on this, this paper takes VR technology to realize interactive display of virtual museum as the research content, analyzes and discusses the present situation of interactive display of virtual museum, puts forward the problem of lack of interactive display in current virtual museum display, and puts forward the idea of building a museum virtual display system platform based on VR technology.

The distributed network structure of blockchain coincides with the market-oriented structure of distributed renewable energy. Blockchain technology can be used to synchronize the real-time price of grid services with real-time phasor control systems to balance microgrid operation, distributed power generation system access, and wholesale market operation. Distributed shared energy networks constructed in different regions and regions carry digital assets of different values. How to realize the credible exchange of energy digital assets across regions is an urgent need facing the current energy interconnection network. At present, there have been many researches on cross-chain asset exchange methods in the blockchain, such as: hash time lock, notary, side chain and so on. However, these asset exchange methods lack proper supervision (KYC&AML) and are inefficient. This article combines distributed digital identities (hereinafter referred to as DID) and verifiable credentials (VC) to propose a DID-based trusted cross-chain asset transfer method.

Recommender system is an applicable technique in most E-commerce commercial product technical designs. However, nearly all recommender system faces a challenge called the cold-start problem. The problem is so notorious that almost every industrial practitioner needs to resolve this issue when building recommender systems. Most cold-start problem solvers need some kind of data input as the starter of the system. On the other hand, many real-world applications place popular items or random items as recommendation results. In this paper, we propose a new technique called ZeroMat that requries no input data at all and predicts the user item rating data that is competitive in Mean Absolute Error and fairness metric compared with the classic matrix factorization with affluent data, and much better performance than random placement.

Modern manufacturing system is a highly decentralized manufacturing system, which consists of many intelligent processing machines, material transportation equipment, robots and various manufacturing resources. With the penetration of internet plus, the deepening of cloud services and the popularization of industrial Internet of Things, PLC (Programmable Logic Controller) should adapt to the demand of intelligent manufacturing from hardware and software. In the intelligent manufacturing process, the production is fully automated and unmanned. Once unreasonable processing technology arrangement occurs, the machine may collide and cause safety accidents. The finite state machine model commonly used in modeling and simulation of manufacturing systems can't deal with complexity and distributed problems, and the functional hierarchy model can only represent data flow, but can't represent control flow, and the description of the system is not accurate enough. In this paper, the digital, networked and intelligent system architecture operation model of intelligent manufacturing system is constructed based on PLC, and the functions of state perception, real-time analysis, independent decision-making and precise execution of intelligent manufacturing system are realized by using the role of big data in intelligent manufacturing system.

The YOLOv3 target recognition algorithm has a wide range of applications in various fields. Under the haze conditions, the recognition effect of the YOLOv3 algorithm is affected, and its mAP value decreases significantly. To solve this problem, it can be improved by adding a dehazing algorithm before the recognition algorithm. In this paper, three commonly used dehazing algorithms are studied, and they are combined with YOLOv3 algorithm to perform target recognition experiments on hazing images. Solve their mAP values separately and compare them. The results show that all the three dehazing algorithms can improve the target recognition ability, and the Retinex algorithm works best.

Vibration isolator is widely used in aerospace, vehicle, ship and other industries, its dynamic stiffness, impedance and other dynamic performance are its core parameters. A large number of test instruments have been developed for dynamic performance test of vibration isolators, but they are usually aimed at low frequency, light load and simple structure of vibration isolators. For vibration isolators with different characteristics, it is usually necessary to carry out specific structural design for their test instruments to avoid resonance and other safety problems during the test. In this paper, the structure design of dynamic performance test instrument for a certain type of high frequency vibration isolator was carried out. Based on the modal analysis of finite element simulation, the beam, column and foundation of the test instrument were optimized. And the variation law of its natural frequency was summarized. The simulation results showed that the optimized test instrument could meet the safety requirements. Its natural frequency was above 1000Hz, which could be used for the next step of production and manufacturing. This study also provided guidance for the structural design of the high frequency dynamic test instrument.
