Refuse landfill intelligent monitoring system and method based on wireless sensor network

Abstract

The present invention provides a refuse landfill intelligent monitoring system and method based on a wireless sensor network. The system comprises uniformly arranged extraction wells in the refuse landfill, the wellhead port of each extraction well is provided with a wireless monitoring terminal, the wireless monitoring terminals of the refuse landfill form one cluster according to five extraction wells or form one cluster according to seven extraction wells to alternately perform network cover in order, the clustering self-organized mode is employed to form a second layer of the wireless sensor network through adoption of first-level cluster head; each wireless monitoring terminal uploads corresponding data in the first-level cluster head, the corresponding data is subjected to compressed sensing through the first-level cluster head and then is sent to a second-level cluster head, and the corresponding data is subjected to compressed encoding through the second-level cluster head and then is uploaded to a remote server; and the remote server decompresses and decodes the received information and analyzes the gas yield condition of each extraction well. Through design of the optimal network topology, the global covering of the whole landfill is ensured, and the two-level clustering layout and the two-level compressed sensing process are performed to allow the monitoring data to be remotely transmitted in real time.

Description

technical field [0001] The invention relates to a wireless sensor monitoring network, in particular to an intelligent monitoring system and method for a garbage landfill based on a wireless sensor network. Background technique [0002] In recent years, with the development of urbanization, domestic waste is increasing day by day, and most of the existing waste disposal methods are landfill. In order to realize the recycling of resources, large-scale landfills usually also recycle the gas generated after landfilling. [0003] Due to the particularity and complexity of the engineering environment, gas extraction wells are usually set up in landfills for gas extraction. Landfill materials usually produce rich gas, and untimely or excessive gas extraction may affect the production of landfills. In order to fully increase the gas production rate of the landfill, it is necessary to monitor the working conditions of each gas extraction well in real time. [0004] The disadvantage...
