【摘要】：集中供熱已經(jīng)走進千家萬戶,供暖質(zhì)量直接影響著成千上萬熱用戶的生活生產(chǎn)。目前對供暖質(zhì)量的監(jiān)測主要基于各個換熱站中的控制器獲取到的入水、回水管道上的溫度數(shù)據(jù),監(jiān)測點極為有限,無法實現(xiàn)對熱網(wǎng)管網(wǎng)的整體監(jiān)測。在本文中,我們利用基于能量采集的無線傳感器網(wǎng)絡(luò)(EH-WSN,Energy Harvesting Wireless Sensor Networks)來對熱網(wǎng)管道進行溫度數(shù)據(jù)采集。這種網(wǎng)絡(luò)利用能量采集技術(shù)從外界環(huán)境中獲取能量并轉(zhuǎn)換為電能為節(jié)點供能,這種網(wǎng)解決了電池供電帶來的電量受限、更換維護困難等問題。由于應(yīng)用場景為熱網(wǎng)管道,我們選擇溫差供能模塊來對節(jié)點進行供能,將溫差能轉(zhuǎn)換為電能,使整個網(wǎng)絡(luò)實現(xiàn)自供能。在網(wǎng)絡(luò)部署上,我們利用大量節(jié)點進行組網(wǎng),節(jié)點通過多跳完成數(shù)據(jù)包的轉(zhuǎn)發(fā)和向Sink節(jié)點的匯聚,Sink節(jié)點再利用GPRS/3G/4G網(wǎng)絡(luò)將數(shù)據(jù)上傳至上層應(yīng)用,上層監(jiān)控平臺對溫度數(shù)據(jù)進行數(shù)據(jù)處理和可視化展示。由于從環(huán)境中采集到的能量不夠穩(wěn)定,所以節(jié)點工作具有間歇性的特點,傳統(tǒng)路由協(xié)議并不適用。通過研究基于溫差供能無線傳感器網(wǎng)絡(luò)的工作特性,我們對兩種傳統(tǒng)路由協(xié)議進行改進,引入節(jié)點剩余能量信息,使得改進后的協(xié)議可以很好的適用于面向熱網(wǎng)監(jiān)測的EH-WSN,保證了良好的網(wǎng)絡(luò)性能。本文通過能量采集技術(shù)和改進的路由協(xié)議實現(xiàn)了對熱網(wǎng)管網(wǎng)的全面監(jiān)測,解決了傳統(tǒng)熱網(wǎng)管道監(jiān)控技術(shù)存在的諸多問題,十分具有研究意義。
[Abstract]:Central heating has entered thousands of households, heating quality directly affects the daily life of thousands of hot users.At present, the monitoring of heating quality is mainly based on the input water obtained by the controller in each heat exchange station, and the temperature data on the backwater pipeline are very limited, so it is impossible to realize the overall monitoring of the heat network pipe network.In this paper, we use EH-WSNN Energy Harvesting Wireless Sensor Network based on energy acquisition to collect the temperature data of hot network pipeline.This network uses energy acquisition technology to obtain energy from the external environment and convert it into electric energy to provide energy for nodes. This network solves the problems of limited power supply caused by battery power supply and difficulty in replacing and maintaining.Because the application scene is hot network pipeline, we choose the temperature difference energy supply module to supply energy to the node, and convert the temperature difference energy into electric energy, which makes the whole network realize the self-supply energy.In the network deployment, we use a large number of nodes to network, the node through multi-hop to complete the transmission of data packets and the convergence to the Sink node sink node, and then use the GPRS/3G/4G network to upload data to the upper application.The upper monitoring platform processes and visualizes the temperature data.Because the energy collected from the environment is not stable, so the node work intermittently, the traditional routing protocol is not applicable.By studying the working characteristics of WSNs based on temperature difference, we improve two traditional routing protocols and introduce the residual energy information of nodes.The improved protocol can be well applied to EH-WSNs for heat network monitoring, which ensures good network performance.In this paper, energy collection technology and improved routing protocol are used to realize the overall monitoring of heat network pipeline network, and many problems existing in the traditional heat network pipeline monitoring technology are solved, which is of great significance.
