A Redundancy Control Method for Internet of Things Data

Abstract

The invention relates to the technical field of data processing, in particular to a method for controlling the redundancy of Internet of Things data, which can be used for transmission after data collection in an urban digital drainage system. The method includes: acquiring a measurement data packet and a first signal strength of each object to be measured in the urban drainage system, and for each area of ​​the urban drainage system, acquiring the second signal strength of each measurement data packet within a preset time period and collecting Corresponding packet loss rate; obtaining the signal stability degree of the corresponding measurement data packet according to the change of the second signal strength; obtaining the interference degree based on the fluctuation of the second signal strength of each measurement data packet; according to the signal stability degree and the packet loss rate Obtain the signal quality of each measurement data packet, and then predict the future signal quality, and determine the number of redundant packets that need to be added when the corresponding measurement data packet is transmitted. The embodiments of the present invention can increase the minimum redundant packets and reduce the transmission power consumption while ensuring the transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for controlling redundancy of Internet of Things data. Background technique [0002] The urban drainage system is an important infrastructure of a modern city and plays a vital role in urban environmental management and urban digital management. For the daily drainage scheduling and supervision of the city and emergency repairs in disaster climates, it is necessary to obtain the urban drainage system. The corresponding data can provide data support for the management and overall planning of the urban drainage system. [0003] However, in the transmission process after the data collection of the urban digital drainage system, the data may be damaged and lost due to interference. Therefore, redundant packets are generally added during the data transmission process. The redundant data in the remaining packets restores these missing information. In order to ensure t...

Problems solved by technology

[0003] However, in the transmission process after the data collection of the urban digital drainage system, the data may be damaged and lost due to interference. Therefore, in the process of data transmission, redundant packets are generally added at the same time. The redundant data in the remaining packets restores these missing information. In order to ensure the accuracy of data transmission and reduce transmission power consumption, it is necessary to determine the number of redundant packets to be added.

[0004] At present, the number of redundant packets is determined by using information such as the packet loss rate fed back by the receiving end to set the redundancy rate. The number of redundant packets required cannot be flexibly judged according to the actual situation, which may cause insufficient or wasted data packets, resulting in Inaccurate or inefficient data transmission
