【摘要】：隨著我國(guó)經(jīng)濟(jì)發(fā)展的不斷加速,建筑行業(yè)有了長(zhǎng)足的發(fā)展逐漸成為是我國(guó)經(jīng)濟(jì)社會(huì)發(fā)展的重要支柱。然而施工安全事故的頻繁發(fā)生為所有建筑行業(yè)工作者敲響了警鐘。目前施工現(xiàn)場(chǎng)的安全管控措施主要依賴于人工監(jiān)管,但施工現(xiàn)場(chǎng)人員的文明程度低,缺乏自我保護(hù)及提前發(fā)現(xiàn)危險(xiǎn)的意識(shí),加之施工現(xiàn)場(chǎng)空間錯(cuò)綜復(fù)雜、人與設(shè)備交叉嚴(yán)重的作業(yè)環(huán)境,使得施工現(xiàn)場(chǎng)中的存在著不同程度的安全隱患,許多危險(xiǎn)源沒有真正的受控。加強(qiáng)建筑行業(yè)施工現(xiàn)場(chǎng)的安全監(jiān)控,做到防范于未然,確保人身安全勢(shì)在必行。本文介紹了當(dāng)前工程施工現(xiàn)場(chǎng)的安全管理狀況,分析了當(dāng)前施工管理中存在的一些問題和管理辦法的局限性。對(duì)目前安全事故類型進(jìn)行分類,探討引發(fā)安全施工的誘因。以解決目前傷亡率最高的高處墜落事故為重點(diǎn)展開后續(xù)研究。介紹CAN總線協(xié)議的相關(guān)內(nèi)容,分析了工作原理及數(shù)據(jù)的基本結(jié)構(gòu)。利用超聲波原理設(shè)計(jì)出基于CAN總線傳輸?shù)臏y(cè)距系統(tǒng),對(duì)系統(tǒng)的硬件選擇給出設(shè)計(jì)方案,并對(duì)如何搭建CAN總線信號(hào)列表進(jìn)行了詳細(xì)闡明,使用CAN Editor對(duì)設(shè)計(jì)方案進(jìn)行了仿真。介紹了RFID系統(tǒng)的構(gòu)成、工作原理和相關(guān)的室內(nèi)定位技術(shù)。通過反復(fù)實(shí)地測(cè)量,確定信號(hào)衰減因子數(shù)值,確定了無線信號(hào)在自由空間內(nèi)傳播的模型。采用CC2530開發(fā)平臺(tái),利用接收信號(hào)強(qiáng)度指示RSSI(Received Signal Strength Indication)方法設(shè)計(jì)出定位方案,建立出測(cè)距模型,并對(duì)系統(tǒng)進(jìn)行仿真計(jì)算出平均誤差值。在實(shí)際工程施工現(xiàn)場(chǎng),模擬施工人員在正常工作時(shí)突然出現(xiàn)不安全行為,驗(yàn)證了系統(tǒng)的可行性。測(cè)試結(jié)果表明本文研究對(duì)提高施工安全管理水平,降低事故發(fā)生率,保障建筑工人的生命健康有一定的作用。
[Abstract]:With the rapid development of China's economy, the construction industry has made great progress and become an important pillar of our country's economic and social development. However, the frequent occurrence of construction safety accidents has sounded the alarm for all construction workers. At present, the safety control measures of the construction site mainly rely on manual supervision, but the construction site personnel have a low level of civilization, lack of self-protection and awareness of finding danger in advance, and the construction site space is complicated. Because of the serious working environment between human and equipment, there are some hidden dangers in the construction site, and many dangerous sources are not really controlled. It is imperative to strengthen the safety monitoring of construction site in construction industry, to prevent it from happening and to ensure personal safety. This paper introduces the current situation of safety management in engineering construction site, analyzes some problems existing in current construction management and the limitation of management methods. The types of safety accidents are classified and the inducements of safety construction are discussed. The following research is focused on solving the high fall accident which has the highest casualty rate at present. This paper introduces the related contents of can bus protocol, analyzes the working principle and the basic structure of data. The ranging system based on can bus transmission is designed by using the principle of ultrasonic wave. The hardware selection of the system is given, and how to set up the can bus signal list is explained in detail, and the design scheme is simulated with can Editor. This paper introduces the structure, working principle and relative indoor positioning technology of RFID system. The signal attenuation factor is determined by repeated field measurements, and the model of wireless signal propagation in free space is established. Based on CC2530 development platform, the location scheme is designed by using the received signal strength indicator (RSSI) method, and the ranging model is established, and the average error value is calculated by simulating the system. At the actual construction site, the unsafe behavior of the construction personnel is simulated, which verifies the feasibility of the system. The test results show that this study can improve the level of construction safety management, reduce the incidence of accidents, and protect the life and health of construction workers.
