Embodiment Construction

[0046] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] A pervasive mobile perception and prediction method for regional environmental information, comprising the following steps:

[0048] Step 1: Use the existing measured environmental data in the cloud database, and use the method of regionalized random variable analysis to analyze the space and structure of these data, and obtain the expressions of covariance and variogram.

[0049] In the step 1, among the existing measured environmental data, if there are two data of the same type at the same latitude and longitude, it is necessary to select the data closest to the time point to be predicted.

[0050] Described step 1 comprises following sub-steps:

[0051] Step 1-1: The target area that needs to detect environmental information is M, and y in the target area M i The value of the measured environmental data collected at is A...

Abstract

The invention relates to a pervasive regional environment information mobile sensing and prediction method, which comprises the following steps: acquiring data by using a mobile sensing node and transmitting the data to a cloud server; performing space and structure analysis on the data by adopting a regionalized random variable analysis method at a cloud end, and obtaining expressions of a covariance and a variation function; using an improved random L-BFGS algorithm to improve a Kriging algorithm, and using the algorithm to carry out pervasive regional environment information space prediction to obtain a space prediction result of the environment information; carrying out space-time prediction analysis by utilizing the relationship between the time and the space of collecting the environment data by the shared bicycle to obtain a space-time prediction result of the target area; and finally, giving a final regional global environment prediction result graph according to different prediction results of time and space.

Description

technical field [0001] The invention relates to the field of data interpolation methods, in particular to a universal mobile perception and prediction method for regional environmental information. Background technique [0002] Ecological environment information is very important in environmental protection: it is very important for environmental scientific research work; it is very important for energy saving and emission reduction; it is very important for urban planning and deployment. The current way to collect environmental information is to arrange a large number of sensor nodes to monitor the ambient air quality in the target area. Wireless sensor networks are easy to deploy and can monitor a wide range of areas, so they can be effectively monitored in areas where power supply is difficult and areas that are difficult for humans to reach. However, a large number of wireless sensor nodes are deployed in cities, which will cause problems such as many redundant nodes, w...
