At present, the new energy vehicle industry is developing rapidly, in order to improve the charging power and efficiency of bi-directional on-board charger, the power factor correction circuit and CLLC resonant converter are cascaded together. The variable DC bus voltage scheme is adopted, and the PFC provides a wide range of DC bus voltage. The CLLC resonant converter works near the resonant point. The switch is made of silicon carbide, which greatly improves the charging and discharging efficiency. Finally, bidirectional on-board charger with a maximum charging power of 11kW and a maximum discharge power of 6.6kW is built and tested. The results show that the maximum efficiency of 11kw/6.6kw charging mode can reach 95.62% and 95.05% respectively, and the maximum efficiency of 6.6kw discharge mode can reach 95.18%.

The traditional construction mode of construction site with CAD as the core is gradually unable to meet the needs of productivity development. Therefore, according to the needs of the national business innovation strategy and the experience of foreign advanced BIM technology, a new engineering project information management system with BIM technology as the core has been formulated. According to the development situation and application status of existing BIM technology at home and abroad, this article summarizes the above-mentioned application results, and analyzes some inherent shortcomings of the existing model. On this basis, targeted access and application of BIM technology are carried out in accordance with the characteristics of the visual operation platform and intelligent construction site. Through the comparison of simulation examples, it is concluded that the intelligent construction site information management level after BIM access has been significantly improved.

With the popularization and application of the Internet, in the intranet system, customers attach great importance to massive data sets such as item information, merchant orders and product details, but they are unable to meet the needs of a large number of dynamic related transactions of goods. However, due to the existence of various redundant data in mainstream business systems on the market, how to use these large amounts of repetitive features to improve the efficiency of business analysis has become an urgent problem to be solved. To this end, this paper proposes to design an intelligent business service system based on the Apriori algorithm to facilitate the development of industrial and commercial service levels. This article mainly uses the collection method and data analysis method to study Apriori's related algorithms, and then uses the experimental method to analyze the operation and module design of the intelligent system, and finally uses the investigation method to understand the people's system construction requirements for intelligent services. The survey results show that 46.1% of people believe that the intelligent business service system should be designed with emphasis on customer participation.

Speaker recognition, also known as voiceprint recognition, as the name implies, is to identify "who is speaking" by sound, and is a biometric identification technology that identifies the speaker's identity based on the speaker's personality information in the voice signal. In this paper, through a survey of speaker recognition literature and related technologies, the two main tasks of speaker recognition, speaker confirmation and speaker recognition, are introduced, and some models in the development of speaker recognition technology are introduced. From the early Gaussian Mixture Model-Universal Background Model, to Joint Factor Analysis and I-vector model, to the emergence of various new feature models combined with deep learning, the recognition effect is getting better and better. Recognizable scenarios are also becoming more complex. Finally, the speaker recognition technology is summarized and its future research is prospected.

In the process of construction, various expenses fluctuate greatly affected by the external environment, and the cost control cannot be completed at one time. It needs to be dynamically adjusted with the actual construction progress and the external environment. The cost control of prefabricated construction is an important part of the construction cost. Because China's prefabricated buildings have not been popularized on a large scale and the relevant integrated design level is relatively backward, the cost of China's prefabricated buildings is relatively high compared with that of traditional buildings. Building cost modeling and control method based on Neural Network – neural network models and controls the building cost by simulating the thinking mode of human brain neurons. BIM technology is a technology integrating architectural design, construction management and project collaborative management, which can improve the efficiency of building management and reduce the construction cost. Based on BIM platform, this paper establishes a database of key factors influencing the cost of similar projects, uses the data in the database to train neural network, and collects real-time cost data of projects under construction based on BIM platform, carries out cost analysis, and completes this control and cost assessment.

With the advent of the era of artificial intelligence, great changes have taken place in the traditional broadcasting of sports games. As early as the early 20th century, the Hawkeye system appeared in tennis as a referee aid. However, there is currently no technology that can perform semantic analysis of live video of tennis matches. In the field of machine vision, target tracking is one of the most basic and important branches. It includes image processing, machine learning, pattern recognition and other aspects. It is a research direction involving a very wide range of fields. The complexity of the environment where the moving objects are located and the uncertainty of the moving objects themselves bring great challenges to the detection and tracking of moving objects. Traditional detection and tracking methods based on manual feature extraction have poor generalization ability and can not meet the needs of target detection and tracking in complex moving scenes. By estimating the two-dimensional posture of the players in the player area, analyzing their body skeleton and key information, the analysis of the players' movement types is completed. At the same time, according to the displacement information of key points of athletes' bodies and the running time of the system, the movement distance and speed of athletes can be obtained.

The rapid rendering of complex 3D scene has always been one of the challenging problems in computer graphics. At present, the most commonly used rendering architecture is the method based on BS architecture. The smooth display method of complex 3D scene based on B / S architecture not only needs to solve the problem of network transmission, but also needs to consider the load caused by complex 3D scene on the server. Because the displayed 3D scene often contains a lot of geometric information and high fidelity texture information, this paper will analyze the characteristics of this kind of scene, and then propose a rendering acceleration method of complex scene based on parallel processing. Parallel processing is adopted. On the other hand, it is also convenient to apply cloud computing technology to the smooth display of complex 3D scenes based on B / S architecture.
