【摘要】：伴隨著21世紀(jì)以來我國(guó)經(jīng)濟(jì)的快速發(fā)展,城市化的不斷推進(jìn),盾構(gòu)掘進(jìn)機(jī)已經(jīng)成為城市基礎(chǔ)建設(shè)必不可少的施工裝備。盾構(gòu)機(jī)工作的掘進(jìn)形式為刀盤切削土體,刀具作為盾構(gòu)工作的基本執(zhí)行元件,刀具的磨損失效將導(dǎo)致整機(jī)停機(jī)開倉(cāng)檢測(cè),降低施工效率,因此對(duì)盾構(gòu)刀具磨損的實(shí)時(shí)監(jiān)測(cè)已成為提高工程效率的必然途徑。本論文以無(wú)線傳輸為設(shè)計(jì)理念,采用現(xiàn)代傳感器技術(shù)、短距離無(wú)線射頻通信技術(shù)、計(jì)算機(jī)接口技術(shù)、GPRS網(wǎng)絡(luò)通信技術(shù)等相結(jié)合設(shè)計(jì)研發(fā)了盾構(gòu)滾刀磨損遠(yuǎn)程監(jiān)測(cè)系統(tǒng)。該系統(tǒng)能夠遠(yuǎn)程實(shí)時(shí)在線監(jiān)測(cè)滾刀當(dāng)前磨損量及工作狀態(tài)等信息,便于工作人員對(duì)刀具的磨損失效及時(shí)做出決策。本文的主要設(shè)計(jì)工作有以下幾部分。1.論文首先分析了國(guó)內(nèi)外對(duì)于盾構(gòu)滾刀磨損檢測(cè)技術(shù)的研究現(xiàn)狀,并根據(jù)系統(tǒng)設(shè)計(jì)要求,確定了系統(tǒng)的總體方案及設(shè)計(jì)原則。2.分析盾構(gòu)刀具的切削原理,確定所需檢測(cè)的物理量,并依據(jù)系統(tǒng)設(shè)計(jì)原則,選擇合適的傳感器,根據(jù)傳感器檢測(cè)原理設(shè)計(jì)相應(yīng)的檢測(cè)方案,尤其是對(duì)電渦流傳感器的位移標(biāo)定與溫度補(bǔ)償進(jìn)行了詳細(xì)的說明。3.完成基于CC1101的現(xiàn)場(chǎng)無(wú)線采集子系統(tǒng)的設(shè)計(jì)。系統(tǒng)硬件設(shè)計(jì)部分主要包含對(duì)無(wú)線射頻模塊CC1101應(yīng)用電路、低功耗MCU外圍電路、電源電路及RS485接口電路等的設(shè)計(jì);軟件設(shè)計(jì)主要包括對(duì)各個(gè)傳感器的采樣機(jī)制和無(wú)線數(shù)據(jù)收發(fā)流程的設(shè)計(jì)并深入分析了系統(tǒng)的低功耗設(shè)計(jì)方案。4.采用GPRS模塊實(shí)現(xiàn)滾刀磨損數(shù)據(jù)的遠(yuǎn)程傳輸。研究GPRS技術(shù)的網(wǎng)絡(luò)結(jié)構(gòu)及特點(diǎn),采用透明模式傳輸TCP網(wǎng)絡(luò)數(shù)據(jù);采用Lab VIEW編寫監(jiān)控中心軟件。5.論文最后對(duì)整個(gè)監(jiān)控系統(tǒng)進(jìn)行軟硬件調(diào)試,并提出對(duì)系統(tǒng)的改進(jìn)方法。經(jīng)現(xiàn)場(chǎng)測(cè)試,本文設(shè)計(jì)的盾構(gòu)滾刀磨損遠(yuǎn)程監(jiān)控系統(tǒng)能夠判斷滾刀的偏磨、斷裂、停轉(zhuǎn)等異�，F(xiàn)象,并且具有低功耗、精度高、可靠性高等優(yōu)點(diǎn),傳感器節(jié)點(diǎn)可以免維護(hù)連續(xù)工作時(shí)長(zhǎng)達(dá)四個(gè)月,具有較好的推廣價(jià)值。
[Abstract]:With the rapid development of economy and urbanization since the 21st century, shield tunneling machine has become an indispensable construction equipment for urban infrastructure construction.The tunneling form of shield machine is cutting soil with cutter head, the tool is the basic executing element of shield machine, the tool wear failure will cause the whole machine to shut down and open the storehouse, and reduce the construction efficiency.Therefore, real-time monitoring of shield machine tool wear has become an inevitable way to improve engineering efficiency.In this paper, the remote monitoring system of shield hob wear is designed and developed based on the concept of wireless transmission, modern sensor technology, short range radio frequency communication technology, computer interface technology and GPRS network communication technology.The system can monitor the current wear amount and working state of hob in real time and can help the workers to make timely decision on tool wear failure.The main design work of this paper is as follows. 1.Firstly, this paper analyzes the research status of shield hob wear detection technology at home and abroad, and determines the overall scheme and design principle of the system according to the system design requirements.This paper analyzes the cutting principle of shield machine tool, determines the physical quantity needed for testing, and according to the system design principle, selects the appropriate sensor and designs the corresponding detection scheme according to the principle of sensor detection.In particular, the displacement calibration and temperature compensation of eddy current sensor are described in detail.The design of field wireless acquisition subsystem based on CC1101 is completed.The hardware design of the system mainly includes the design of radio frequency module CC1101 application circuit, low power MCU peripheral circuit, power circuit and RS485 interface circuit.The software design mainly includes the sampling mechanism of each sensor and the design of wireless data transceiver flow, and deeply analyzes the low power design scheme of the system.GPRS module is used to realize remote transmission of hob wear data.This paper studies the network structure and characteristics of GPRS technology, adopts transparent mode to transmit TCP network data, and uses Lab VIEW to program monitoring center software .5.Finally, the software and hardware of the whole monitoring system are debugged, and the improvement method of the system is put forward.Through the field test, the remote monitoring system of shield hob wear designed in this paper can judge the abnormal phenomena of hob, such as partial wear, fracture and stop turning, and has the advantages of low power consumption, high precision, high reliability, etc.Sensor nodes can be maintenance-free for up to four months, which has a good promotion value.
