【摘要】：隨著社會與經(jīng)濟的發(fā)展,管道輸送已經(jīng)成為一種對世界經(jīng)濟發(fā)展有著極其重要影響的運輸方式。由于管道老化、腐蝕以及自然或人為等原因所導(dǎo)致的管道泄漏事故頻繁發(fā)生,不僅造成經(jīng)濟上的巨大損失,而且還破壞了生態(tài)環(huán)境,威脅著人們的生命安全,因此研究并建立一套管道泄漏監(jiān)測系統(tǒng)具有重要的現(xiàn)實意義。本文以“數(shù)據(jù)采集—數(shù)據(jù)傳輸—遠程數(shù)據(jù)接收”為研究路線,通過設(shè)計數(shù)據(jù)采集節(jié)點、匯聚節(jié)點兩大大功能模塊,采用Zig Bee技術(shù)和GSM技術(shù)實現(xiàn)了從傳感器到遠程監(jiān)控主機的數(shù)據(jù)傳輸。其中,數(shù)據(jù)采集節(jié)點和匯聚節(jié)點中的協(xié)調(diào)器之間通過使用ZStack協(xié)議組建了一個Zig Bee星型無線網(wǎng)絡(luò),完成對管道現(xiàn)場數(shù)據(jù)采集任務(wù);匯聚節(jié)點完成現(xiàn)場數(shù)據(jù)與遠程監(jiān)控中心間的數(shù)據(jù)傳輸任務(wù)。數(shù)據(jù)采集節(jié)點以無線SOC芯片CC2530為核心處理器,針對管道端點壓力、溫度、流量三個物理特性,選用了相應(yīng)的傳感器進行測量,實現(xiàn)對管道泄漏相關(guān)物理參數(shù)的感知;匯聚節(jié)點采用“無線MCU(CC2530)+主控MCU(STM32F103)+GSM模塊”架構(gòu)完成了Zig Bee無線網(wǎng)絡(luò)與GSM網(wǎng)絡(luò)的無縫連接,最終實現(xiàn)了數(shù)據(jù)的遠程傳輸功能。最后對所設(shè)計系統(tǒng)做了功能測試。測試結(jié)果表明,該管道監(jiān)測系統(tǒng)運行狀況良好,基本上達到設(shè)計要求,能夠完成對管道運行參數(shù)的采集和傳輸,準(zhǔn)確反映管道運行的工作狀態(tài)。
[Abstract]:With the development of society and economy, pipeline transportation has become a kind of transportation mode which has an extremely important influence on the development of world economy. Pipeline leakage accidents caused by pipeline aging, corrosion and natural or man-made causes occur frequently, which not only cause huge economic losses, but also destroy the ecological environment and threaten people's lives. Therefore, it is of great practical significance to study and establish a set of pipeline leakage monitoring system. In this paper, "data acquisition-data transmission-remote data reception" as the research route, through the design of data acquisition node, convergence node two large functional modules, Zig Bee technology and GSM technology are used to realize the data transmission from sensor to remote monitoring host. Among them, a Zig Bee star wireless network is constructed between the data acquisition node and the coordinator in the sink node by using ZStack protocol to complete the field data acquisition task of the pipeline. The sink node completes the data transmission task between the field data and the remote monitoring center. The data acquisition node takes wireless SOC chip CC2530 as the core processor. According to the three physical characteristics of pipeline end pressure, temperature and flow, the corresponding sensor is selected to measure the physical parameters related to pipeline leakage. The sink node adopts the architecture of "Wireless MCU (CC2530) main Control MCU (STM32F103) GSM Module" to complete the seamless connection between Zig Bee wireless network and GSM network, and finally realizes the remote transmission function of data. Finally, the function of the designed system is tested. The test results show that the pipeline monitoring system is in good condition, basically meets the design requirements, can complete the collection and transmission of pipeline operation parameters, and accurately reflect the working state of pipeline operation.
