Abstract

The invention discloses a time correlation redundancy removal method for temperature sensing data, and the method comprises the steps of 1, obtaining the temperature sensing data collected by a plurality of temperature sensors, and carrying out the preliminary processing on the temperature sensing data; 2, calculating the similar distance between the currently acquired temperature sensing data andthe data in a temporary data set; 3, calculating the farthest time difference of the continuous redundant temperature sensing data in each period, setting a threshold value of the similar distance and a numerical value of maximum time control, comparing the similar distance with the threshold value of the similar distance, and comparing the farthest time difference with the numerical value of themaximum time control to serve as a redundant condition for judging redundancy; adding a dynamic step length to control the comparison quantity during calculation; and 4, outputting the temperature sensing data after time correlation redundancy removal. According to the method, the special data can be reserved, the problem of the excessive data loss caused by the excessive redundancy elimination is solved, and the temperature sensing data is more reasonable during the redundancy elimination process and more conforms to the acceptance form of a user.

Description

technical field

[0001] The invention relates to the technical field of wireless sensor networks, in particular to a time-correlation de-redundancy method for temperature sensing data. Background technique

[0002] With the advancement of social science and technology, wireless sensor networks are used in all aspects of life (such as: medical treatment, trajectory, earthquake, military, Internet of Things, agricultural and industrial pollution monitoring, etc.), providing people with a large amount of monitoring data all the time. Due to the limitations of the sensor network's own conditions, limited battery energy, memory, capacity and communication range, etc., limit the life of the network. The life of the network mainly depends on the battery energy, and the energy consumption is manifested in three aspects: node communication, data processing and data transmission. With the sharp increase of sensing data, a large amount of data transmission will be generated, which will...
