In order to improve the comprehensive analysis and application capabilities of tobacco silk processing, production quality and other data, a set of electric energy data collection and analysis system for high data throughput in the silk workshop was designed. The system realized the aggregation and interaction of heterogeneous data based on the protocol gateway and Cassandra data warehouse. It implemented task creation, management and abnormal analysis through adopting Spring Batch processing technology and a stream and aspect-oriented task management. The task real-time scheduling was implemented with Quarzt and the peak elimination of the collection was achieved with RabbitMQ message middleware. The message could be efficiently shown to users by MQTT protocol and Vue front-end technology. Finally, the system could realize the whole process function from data scheduling, storage, analysis to presentation. The test results showed that the system had small access delay, strong carrying capacity and stability, and could meet the power data analysis needs of tobacco companies' silk workshops.

From the new respect of urban energy and land factor allocation structure constraint, we explored the win-win path of high-quality economic development and environmental protection. To be more specific, taking 280 cities in China from 2004 to 2017 as samples, we measured urban green total factor productivity ( GTFP) based on the SBM-Luenberger production function method. Furthermore, we analyzed the sources, dynamic characteristics, and internal driving factors of the growth of GTFP and found that: (1) The growth of GTFP experienced three stages during 2014 -2017: the positive growth stage (2004-2008), the negative growth stage (2009-2015) and the positive growth stage again (after 2016). The growth of GTFP mainly came from its scale effect. (2) In the spatial-dynamic change, the spatial HH region (high-growth level) of GTFP in the initial stage was concentrated in the western region, while the LL region (low-growth level) of the GTFP was in Fujian, Jiangsu, Zhejiang, Heilongjiang, and other eastern regions. With the time passing by, the HH region had been expanding from the western region to the central region and Beijing-Tianjin-Hebei region. However, the LL region of the eastern coastal region was narrowing. (3) Among the driving factors, the negative effect of urban energy structure was related to a low proportion of new energy power supply. The negative effect of land supply structure indicated a 'race-to-the-bottom' effect in urban development. The advanced process of industrial structure was good for the growth of GTFP but negative with the local environment. In addition, the stronger the urban resource agglomeration effect was, the higher the growth speed of GTFP was. Therefore, we should give full play to the scale effect of urban agglomeration and improve the intensive efficiency of urban energy and land resources, and finally enhance the urban high-quality economic development relying on the improvement of economic efficiency, resource efficiency, and environmental efficiency.
