Smart Instrumentation Helps Accelerate the Development of Smart Cities

In 2019, my country's urbanization rate was 60.6%. As the most populous country in China, the process of urbanization is inevitable. The process of global urbanization is advancing in an unstoppable trend, and by 2050, nearly 70% of the world's population will live in cities. In order to solve urban development problems and achieve sustainable urban development, building a smart city has become an irreversible historical trend. So, what is a smart city? What role does intelligent instrumentation play in it? What is a smart city? A smart city is a smarter method that senses, transmits, integrates and analyzes various key information of the core system of city operation by using a new generation of information technology means centered on the Internet of Things, cloud computing, etc. Quickly and intelligently respond to various needs including urban services, environmental protection, and public safety, improve urban operation efficiency, and create a better urban life for people. According to IDC's 'Global Semi-annual Smart City Expenditure Guide', the scale of my country's smart city technology-related investment in 2018 was US$20.053 billion, a year-on-year increase of 15.91%; in 2019, China's smart city technology-related investment is expected to reach US$22.879 billion, compared with $20.053 billion increased by 14.09%. The construction of a smart city mainly includes the following levels: the first is the perception terminal layer, which obtains urban system data in an all-round way through deep perception; the second is the communication network layer, which is the communication network infrastructure. Including fixed network broadband, mobile network, Internet of Things, private network, etc., as the pipeline of information data transmission; the third is the service platform layer, which is the data platform infrastructure for storing, exchanging, analyzing and processing data information, through a high degree of sharing 、Intelligent analysis turns information into knowledge; the last is the urban application layer, which integrates knowledge and information technology and applies it to all walks of life to form wisdom. So, do you know what role smart instruments play in the construction of smart cities? Building a smart city is inseparable from smart instruments. First, the perception terminal layer. To perceive a city, it is inseparable from the smart sensors in the instruments. As the heart of the Internet of Things, sensors play an important role in the construction of smart cities. effect. It can convert the received information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information processing, storage, display, recording, transmission and control. The second is the communication network layer. In building a communication network, electronic measurement instruments are indispensable. Communication test instruments are dedicated to testing communication lines and parameters in the communication process, while signal analysis instruments are used to observe, analyze and record various electrical Signal changes, such as various oscilloscopes (including analog oscilloscopes and digital oscilloscopes), waveform analyzers, distortion analyzers, harmonic analyzers, spectrum analyzers, and logic analyzers. The third is the service platform layer. To build the data platform infrastructure, a data acquisition system is needed. It also automatically collects non-electricity or electric energy signals from analog and digital measured units such as sensors and other equipment to be tested, and sends them to the host computer for processing. analyze, process. Smart cities better serve everyone. The fourth is the urban application layer. Through cloud computing and big data technology in instrumentation, intelligent means are used to process, analyze and manage the entire city, and promote the smooth and coordinated flow of people, logistics and traffic in the city. Through the above technologies, to achieve the integration of knowledge and information technology, apply to all walks of life to form wisdom, in order to build a smart city. Building a smart city is inseparable from instrumentation, especially the application of sensors. Without 'smart sensing', the 'Internet of Everything' cannot be achieved. In my country, various urban areas are also building smart cities from reality. In 2012, the promulgation of the 'Interim Measures for the Administration of National Smart City Pilots' opened the prelude to the construction of my country's smart cities. Beginning in 2016, the “13th Five-Year Plan” of the state and various provinces and cities was released, making smart city construction the focus of future urban development. At the same time, policy documents proposed incentive measures for smart city construction from the perspectives of overall structure and specific applications. The promulgation and implementation of a series of policies is the direction and goal of my country's smart city construction. For example, Shanghai has successively issued relevant documents such as 'Several Opinions on Further Accelerating the Construction of Smart City' and 'Shanghai Action Plan for Promoting New Infrastructure Construction (2020-2022)'. Start the planning and layout of smart city construction, identify breakthroughs according to local conditions, focus on key points such as new infrastructure construction, 'one-stop service' for government services, and 'one-network unified management' for urban operations, increase construction efforts, and introduce a package of informatization support policies. Press The 'accelerator' of smart city construction. Guangzhou, 'Guangzhou Informatization Development Thirteenth Five-Year Development Plan (2016-2020) to accelerate the construction of salary-type smart city belt, by 2020,Guangzhou has built a smart traffic perception network. The smart traffic perception platform covers the core area, main and secondary roads, city entrances and exits, etc., and the number and flow of passengers in the passenger hub and bus station will also be monitored in real time. Build smart cities.
