The two sides will continue to carry out in-depth comprehensive cooperation between industry, university and research and promote more cooperation results.

Digital Twin Technology

Make full use of data such as physical models, sensor updates, operating history, and integrate multi-disciplinary, multi-physical, multi-scale, and multi-probability simulation processes to complete the mapping in the virtual space, thereby reflecting the full life cycle process of the corresponding physical equipment. Digital twin is a concept that transcends reality and can be regarded as a digital mapping system of one or more important, interdependent equipment systems. Digital twin is a universally applicable theoretical and technical system that can be applied in many fields. Currently, it is widely used in product design, product manufacturing, medical analysis, engineering construction and other fields. Various simulations, analyses, data accumulation, mining, and even the application of artificial intelligence based on digital models can ensure its applicability with real physical systems. This is what Digital twin means to smart manufacturing.

The three components of the digital twin: physical products in physical space, virtual products in virtual space, and data and information interaction interfaces between physical space and virtual space. At present, the most in-depth application in China is in the field of engineering construction, and the field of intelligent manufacturing is the most concerned and the hottest research. The simulation analysis and prediction of a new generation of information technology such as over-big data analysis and artificial intelligence in the virtual world drive the operation of the physical world with the best results. The essence of digital twins is the equivalent mapping of the information world to the physical world. Therefore, digital twins better interpret CPS and become the best technology to realize CPS.

Blockchain technology

It is one of the ten typical judicial technology applications of the Internet. Blockchain involves many scientific and technological issues such as mathematics, cryptography, the Internet, and computer programming. From an application perspective, in simple terms, the blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, traces throughout the process, traceability, collective maintenance, openness and transparency. These features ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the creation of trust in the blockchain

Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptography. Each The data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. The blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Blockchain can also be naturally combined in the Internet of Things and logistics. Through the blockchain, logistics costs can be reduced, the production and delivery processes of items can be traced, and the efficiency of supply chain management can be improved. This field is considered to be a promising application direction of blockchain.

Network isolation technology

It means that two or more computers or networks realize information exchange and resource sharing on the basis of disconnection. Through the network isolation technology, the two networks can be physically separated, and data can be exchanged in a secure network environment. The main goal of network isolation technology is to isolate harmful network security threats to ensure the safe interaction of data and information within a trusted network. At present, the general network isolation technology is based on access control thinking and physical isolation, and defines related constraints and rules to ensure the security strength of the network.

The key point of network isolation technology is how to effectively control data information in network communication, that is, to complete data exchange between internal and external networks through dedicated hardware and security protocols, and to use security mechanisms such as access control, identity authentication, and encryption signatures to achieve data exchange. The confidentiality, integrity, availability, and controllability of the network, so how to maximize the speed of data exchange between different networks and transparently support the security of interactive data will be the future development trend of network isolation technology.

City brain

It is a digital interface for urban life. Citizens use it to touch the pulse of the city, feel the temperature of the city, and enjoy city services. City managers use it to allocate public resources, make scientific decisions, and improve governance efficiency. Taking Hangzhou as an example, the urban brain includes 11 major systems and 48 application scenarios such as police, transportation, cultural tourism, and health, with an average daily data of more than 80 million. The main screens of each platform and system are presented in the form of a digital cockpit. The digital cockpits of each platform are developed around the visual content of economy, politics, culture, society and ecology, and the digital cockpits of each system are laid out around the visual content of the work responsibilities, work areas and work priorities of each unit. In addition to the large-screen version of the digital cockpit, there is also a mobile version for easy mobile applications. Through big data, cloud computing, artificial intelligence and other means to promote the modernization of urban governance, big cities can also become more "smart". From informatization to intelligence to intelligence, it is the only way to build a smart city, with broad prospects.

Environmental data monitoring

Comprehensive use of advanced technologies such as computers, databases, and communication networks to promote a data management system for environmental protection technology. The main users are information auditors, data reporters, and system administrators. With environmental monitoring, pollution reporting and management as the core, the software system is designed with a B/S structure to provide data support for comprehensive environmental decision-making. The monitoring data management information system mainly includes three types of users in practical applications, namely, information auditors, data report officers, and system administrators. Environmental monitoring is generally divided into two parts: monitoring monitoring and specific monitoring according to the purpose of detection. In the system design, the modules are divided into monitoring monitoring subsystems and specific monitoring subsystems with reference to the monitoring purpose. The system mainly revolves around water quality monitoring, air quality monitoring, waste monitoring, and noise monitoring routine monitoring, realizing quality data management, statistical analysis, and forecasting. The key data is displayed at all times in drawing environmental quality maps, which are reflected in a more intuitive way.
