Numerical type sensor data filtering and transmitting method oriented to crowd sensing application

Abstract

The invention discloses a numerical type sensor data filtering and transmitting method oriented to a crowd sensing application. The method comprises the following steps: 1) acquiring data through a sensor, and storing the data in a cache; 2) processing the data newly added in the cache one by one by use of a moving average method so as to filter random error of the data; 3) judging the size of the current cache, and executing the following step 4) if the size of the current cache achieves a set threshold value, or returning to the above step 1); 4) writing the data in the cache in a file to store, and then emptying the cache; 5) computing the time interval between the former transmission and the current, and executing the step 6) if the time interval achieves the set threshold value, or returning to the step 1); and 6) naming the file in the step 4) by use of the current time, and transmitting the file to a server-side according to a set grouping transmission strategy. Based on the crowd sensing environment, the method can be generally applied to the crowd sensing application of the numerical type sensor, and the practicability and the universality are realized.

Description

technical field [0001] The invention relates to the field of crowd sensing and mobile computing, in particular to a method for filtering and transmitting numerical sensor data oriented to crowd sensing applications. Background technique [0002] In recent years, with the rapid development of wireless communication technology and smart mobile devices, computer applications for mobile terminals have become increasingly popular, and the concept of "crowd intelligence" has become more and more well known. It is a new trend of mobile computing and an important part of the development of smart cities to collect a large amount of data through multiple mobile sensors in the group, and give each individual advice and assistance that meets their needs after analysis and processing. [0003] A variety of sensors are installed on the mobile terminal, and the readings of the numerical sensor are all numerical values. They are also the sensors with the largest number and types of various ...
