【摘要】：近年我國各地的基礎(chǔ)設(shè)施建設(shè)飛速發(fā)展，起重機(jī)械在社會工程建設(shè)中扮演著越來越重要的角色。起重機(jī)械是建筑工程中重要的施工機(jī)械，也是極易發(fā)生重大安全事故的特種作業(yè)機(jī)械，其自身結(jié)構(gòu)蘊(yùn)含的危險(xiǎn)因素較多。隨著起重機(jī)的工作日趨繁重，起重機(jī)事故發(fā)生率也越來越高，對人們的生命財(cái)產(chǎn)安全構(gòu)成了很大威脅。因此，對起重機(jī)進(jìn)行有效的健康監(jiān)測將具有重大意義。為此，本文針對起重機(jī)的健康監(jiān)測提出一種新型的、成本較低的、基于電阻應(yīng)變片和RS-485總線的、多點(diǎn)式健康監(jiān)測系統(tǒng)，此系統(tǒng)的成功研制將大大有助于結(jié)構(gòu)健康監(jiān)測思想及技術(shù)走進(jìn)實(shí)際的工程機(jī)械監(jiān)測應(yīng)用。 本文提出一種新型電阻應(yīng)變片封裝方式，設(shè)計(jì)出一種適用于健康監(jiān)測系統(tǒng)的專用電阻應(yīng)變片，提出在起重機(jī)上基于電阻應(yīng)變片和RS-485總線進(jìn)行實(shí)時(shí)、多點(diǎn)式監(jiān)測的方法，并在此基礎(chǔ)上設(shè)計(jì)開發(fā)一套新型起重機(jī)健康監(jiān)測系統(tǒng)。此起重機(jī)健康監(jiān)測系統(tǒng)采用所研發(fā)的專用電阻應(yīng)變片作為傳感器，各監(jiān)測點(diǎn)傳感器采集到的監(jiān)測信息通過RS-485總線傳送給無線終端，再由無線終端通過GPRS網(wǎng)絡(luò)發(fā)送至無線服務(wù)器，然后可由多個(gè)安裝了該系統(tǒng)分析軟件的起重機(jī)監(jiān)測客戶端通過Internet訪問無線服務(wù)器的方式來讀取監(jiān)測信息，可實(shí)現(xiàn)多個(gè)客戶端同時(shí)對起重機(jī)實(shí)時(shí)監(jiān)測，進(jìn)而實(shí)現(xiàn)起重機(jī)健康狀況的多級監(jiān)測管理。經(jīng)科技查新，本課題是首次提出基于RS-485總線的多點(diǎn)式起重機(jī)健康監(jiān)測系統(tǒng)開發(fā)，，也是首次將其成功應(yīng)用在起重機(jī)的健康監(jiān)測領(lǐng)域。 本文對所提出的起重機(jī)健康監(jiān)測系統(tǒng)進(jìn)行理論分析、硬件電路設(shè)計(jì)與開發(fā)、分析軟件設(shè)計(jì)與開發(fā)、實(shí)驗(yàn)室內(nèi)實(shí)驗(yàn)驗(yàn)證、不同健康監(jiān)測系統(tǒng)的性能對比分析，實(shí)驗(yàn)結(jié)果證明該監(jiān)測系統(tǒng)性能較為理想，隨后將系統(tǒng)成功應(yīng)用在了中國長航船舶重工金陵造船廠內(nèi)的一臺15噸橋式起重機(jī)和一臺300噸門式起重機(jī)的健康監(jiān)測，現(xiàn)場應(yīng)用效果良好。
[Abstract]:In recent years, with the rapid development of infrastructure construction in China, lifting machinery plays an increasingly important role in the construction of social engineering. Lifting machinery is one of the most important construction machinery in construction engineering. It is also a kind of special working machinery which is prone to serious safety accidents. Its structure contains many dangerous factors. With the increasingly heavy work of cranes, the incidence of crane accidents is increasing, which poses a great threat to the safety of people's lives and property. Therefore, effective health monitoring of cranes will be of great significance. Therefore, this paper presents a new, low-cost, multi-point health monitoring system based on resistive strain gauge and RS-485 bus for crane health monitoring. The successful development of this system will greatly contribute to the application of structural health monitoring ideas and techniques to practical engineering machinery monitoring. In this paper, a new type of resistive strain gauge packaging method is proposed, and a special resistance strain gauge suitable for health monitoring system is designed. The method of real-time and multi-point monitoring based on resistive strain gauge and RS-485 bus on crane is put forward. On this basis, a new crane health monitoring system is designed and developed. The crane health monitoring system uses the developed special resistance strain gauge as the sensor, and the monitoring information collected by the sensors at each monitoring point is transmitted to the wireless terminal through the RS-485 bus. Then the wireless terminal is sent to the wireless server through the GPRS network, and then the monitoring information can be read by a plurality of crane monitoring clients which have installed the system analysis software and access the wireless server through the Internet. Multiple clients can monitor the crane in real time at the same time, and then realize the multi-level monitoring and management of crane health. After scientific and technological innovation, this subject is the first time to put forward the development of multi-point crane health monitoring system based on RS-485 bus, and it is also the first time to successfully apply it in the field of crane health monitoring. In this paper, the proposed crane health monitoring system theory analysis, hardware circuit design and development, analysis software design and development, laboratory experimental verification, performance comparison and analysis of different health monitoring systems, The experimental results show that the performance of the monitoring system is satisfactory, and the system has been successfully applied to the health monitoring of a 15-ton bridge crane and a 300-ton gantry crane in Jinling Shipyard of China long distance Shipping Company. The effect of field application is good.
