1. The field of science and technology to which the project belongs: With the development of science and technology and the efficient application of big data, digitalization and information construction have received widespread attention and utilization. Many cities have carried out the construction of municipal facility management systems, but the structure of individual systems is loose and the construction cost is high. Information between various municipal systems is not interconnected, and the utilization rate of big data and intelligence is not high. amp;ldquo; Smart Municipal Industry Application System rdquo; is committed to building a municipal management portal, integrating multiple municipal subsystems such as lighting, bridges, roads, gardens, sanitation and network management to build a comprehensive management and maintenance platform for smart municipal governments. Taking system integration and information interaction as the basic architecture, it realizes the sharing of basic data in the municipal industry, conducts unified management and trend analysis of operational data, improves municipal management efficiency, reduces operating costs, and creates a smart municipal ecosystem. amp;ldquo; Smart municipal industry application systemrdquo; It uses smart information software for integrated management and belongs to the field of information technology. 2. Main technological innovation content: ldquo; smart municipal industry application system rdquo; Relying on various information technologies such as Internet of Things technology, intelligent sensing technology, spatial analysis technology, and process customization technology, we use ldquo; one map, one platform, and transparent application rdquo; as the guiding ideology, establish a unified smart municipal platform. By collecting and managing a large amount of municipal industry operation data in real time, conducting trend analysis on the operation of public facilities, supervising and managing urban engineering facilities, public facilities, and city appearance environment, forming an intelligent information-based comprehensive management model, and realizing the sharing of basic data and information of municipal facilities. Collaborative work goals are to reduce duplication of work among various departments, reduce human resource costs of relevant departments at all levels, improve management timeliness and collaboration, and achieve all-round supervision and unified command and dispatch. Through the monitoring and analysis of three-dimensional data, it provides strong decision support for management departments in daily management and protection, construction planning, command and dispatch, improves on-site disaster prevention and early warning and judgment capabilities, and ultimately improves urban municipal management level and management efficiency. 3. Technological innovation and advancement: 1. Use Beidou displacement monitoring equipment to dynamically monitor bridges, design bridge BCI technology evaluation models and methods, and combine ldquo; dynamic monitoring rdquo; and ldquo; static evaluation rdquo; to build a scientific bridge health assessment method. 2. Introduce a vegetation growth model and monitor soil in real time through soil temperature and humidity sensors to realize automatic control of garden irrigation, realize reasonable application of water resources, and realize intelligent garden irrigation technology. 3. Through radio frequency identification technology RFID, RFID tags are installed on sanitation base stations and surveillance video equipment are set up to realize a dynamic monitoring system for sanitation operations. 4. Create a three-dimensional pipe network model, use aerial and satellite images, terrain elevation data, and second-and three-dimensional geospatial and attribute data to realize three-dimensional underground pipeline roaming and comprehensively manage urban underground pipelines. 5. Create a smart municipal management service and operation model, realize the coordination of smart municipal management, service and operation through the dual dimensions of vertical stakeholders and horizontal related industries, and improve the level of management services. 4. Intellectual property rights and promotion and application: 2 papers were published on related technologies of this project, and a total of 7 intellectual property rights were applied for. During the actual review of 3 invention patents, 1 invention patent and 3 software copyrights were authorized. The promotion of this project adopts a combination of vertical and horizontal methods to promote the ldquo; smart municipal industry application systemrdquo; platform from the construction committee or municipal bureau level, and the corresponding municipal industry subsystem is promoted and operated separately. Since the application and promotion of results in 2016, 283 customers across the country have been using this platform, covering a total of 661 cities in large, medium and small cities. The cumulative economic benefits generated were 73.5579 million yuan, saving nearly 8 million yuan in economic expenditure for municipal construction, and accumulating good economic benefits. This project will continue to expand into the smart municipal industry in the future, fill gaps in the industry, and seek new economic development points.
