Internet of things join hands cloud computing sail Intelligent Environmental protection

China's http://www.aliyun.com/zixun/aggregation/30993.html "> Environmental monitoring work started in the middle of the last century 70." 1971, Beijing, "Waste" management Office new business: The organization of relevant departments to the atmosphere, water, noise, soil and other environmental factors and pollution source monitoring, marking the official launch of China's environmental testing work. Because of the late start, compared with some European countries, China's environmental protection system management monitoring means of long-term lag. "Management relies on experience, pollution depends on the eye, charging by estimating" vivid description of environmental protection monitoring and management of the embarrassing situation. To change this backward situation, through automation, information technology and other technical means to strengthen on-site environmental law enforcement, from 2007 onwards, China invested 745 million yuan, local matching more than 9 billion yuan to start national control of key pollution sources automatic monitoring capacity building.

Recently, with the increasing of air pollution in China, the PM2.5 pollution of most cities in China is especially serious. January 14, 2013, the National environmental analysis of the People's Republic of China reported that less than 1% of the 500 large Chinese cities have reached the WHO air quality standards, P M 2.5 severely exceeded the standard is one of the important factors causing serious air pollution in China. However, according to statistics, at present, there are 56 cities in China have the monitoring conditions for PM2.5, there are more than 600 PM2.5 monitoring points. After preliminary calculation, in the "Twelve-Five" period, China to build more than 1500 monitoring points, the upfront needs of the input will be more than 2 billion yuan, the annual new costs will also exceed 100 million yuan.

February 29, 2012, when the State Council premier Wen Jiabao presided over the State Council executive meeting, agreed to issue the new revised "Environmental Air quality standards", the deployment of strengthening integrated air pollution prevention and control efforts. The new standard adds a 8-hour concentration limit monitoring index for fine particulate matter (PM2.5) and ozone (O3). The meeting requested 2012 in Beijing-Tianjin-Hebei, Yangtze River Delta, the Pearl River Delta and other key regions, as well as municipalities and provincial capital cities to carry out the monitoring of fine particulate matter and ozone, 2013 in 113 key cities and national environmental protection Model City monitoring, 2015 coverage of all cities and above. However, the traditional monitoring equipment monitoring interval is long, the equipment cost is expensive, the monitoring point little data is not comprehensive, can not reflect a region such as the city, the province PM2.5 monitoring result, cannot satisfy our country large-scale monitoring deployment. How to intelligently monitor the PM2.5 is always the problem that the environmental department wants to solve.

With the development of IT technology, IoT and cloud computing, as a major strategic emerging industry in China during the 35 period, is widely used in "Smart city", "intelligent transportation", "intelligence communication" and other public management construction areas, successfully resolved the traditional information equipment data storage and storage, difficult to collect, real time poor, high cost, Operational and maintenance management cumbersome and other shortcomings. For example, the recent Nanjing cloud storage launched the collection of IoT and cloud computing technology as one of the large-scale deployment of PM2.5 monitoring, storage and processing platform. This project is based on IoT technology, through the collection deployed in large-scale low-cost perceptual sensing monitoring point (can be deployed in street lamps, telephone poles) real-time data, architecture cloud computing mass data processing platform for environmental monitoring data warehousing and related query second-level response, support automatic fault tolerance and dynamic expansion, can be to mobile phones, Computer and other terminals in real time release data and the evolution process, for environmental monitoring, environmental protection enforcement and other scientific and technological basis, accurate, timely and comprehensive reflection of environmental quality status quo and development trends for environmental management, pollution source control, environmental planning and so on to provide scientific basis.
