【摘要】：在礦用大型機械工作過程中,因為長時間服役于井下空間,掘進齒輪、聯(lián)動裝置、關(guān)鍵機械部位由于長時間和礦石、煤炭等堅硬礦物質(zhì)處于磨損狀態(tài),所以極易發(fā)生機械斷裂、漏電等危險事故,而這些危險因素在發(fā)生前往往有振動頻率異常、關(guān)鍵部位突然升溫等情況出現(xiàn),所以對礦用機械進行關(guān)鍵工作部位的溫度、振動監(jiān)測很有必要。而有線方式因為線路纏繞不能廣泛實施,無線傳感技術(shù)(WSN)卻能夠有效解決這一問題。并且WSN(無線傳感器網(wǎng)絡(luò))的核心問題就是功耗,所以設(shè)計了一個對礦用機械工作狀態(tài)進行實時監(jiān)測的低功耗無線傳感節(jié)點,在實現(xiàn)信息的實時傳輸、處理、顯示、記錄和控制都能滿足的前提下盡量實現(xiàn)低功耗。課題以實時監(jiān)測礦用大型機械的在線狀態(tài)為目的,結(jié)合礦用設(shè)備安全性標準,設(shè)計了監(jiān)測傳感節(jié)點的設(shè)計。設(shè)計的能源管理部分使用LTC3331芯片,能夠?qū)崿F(xiàn)環(huán)境能量采集管理和鋰電池管理共同工作的方式;主控制部分使用MSP430F5438微控制器,來控制傳感數(shù)據(jù)的采集;傳感部分的兩個傳感器,溫度傳感器使用DS18B20實現(xiàn)溫度數(shù)據(jù)采集,振動傳感器使用ADXL345實現(xiàn)振動數(shù)據(jù)采集;無線發(fā)射部分使用CC2530實現(xiàn)傳感數(shù)據(jù)的發(fā)送,送達到上位機上進行顯示。軟件語言編寫部分使用配套的IAR平臺進行程序語言的燒錄。最終的傳感節(jié)點在實驗室環(huán)境、模擬真實環(huán)境當(dāng)中得到了有效測試,采集數(shù)據(jù)真實反映環(huán)境參數(shù),整體功耗維持在171.039mW以下,在10米的通信距離范圍內(nèi)可以實現(xiàn)實時傳輸。初步達到了低功耗、體型小、安裝靈活的要求,提高了系統(tǒng)監(jiān)測的壽命與準確度,能夠有效地預(yù)防故障的發(fā)生。
[Abstract]:In the working process of large-scale mining machinery, because of long time service in underground space, driving gear, linkage device, key mechanical parts because of long time and ore, coal and other hard minerals in a state of wear. Therefore, it is easy to occur mechanical fracture, leakage and other dangerous accidents, and these risk factors often have abnormal vibration frequency before the occurrence, the key parts suddenly warming up and so on. Therefore, it is necessary to monitor the temperature and vibration of the key parts of mine machinery, while the wired way can not be widely implemented because of wire winding. WSNs can solve this problem effectively, and the core problem of WSNs is power consumption. Therefore, a low-power wireless sensor node is designed to real-time monitor the working state of mining machinery, which can realize the real-time transmission, processing and display of information. The purpose of this project is to monitor the online status of large-scale mining machinery in real time and combine with the safety standard of mine equipment. The design of the monitoring sensor node is designed. The energy management part of the design uses LTC3331 chip, which can realize the environmental energy acquisition management and lithium battery management working together. The main control part uses MSP430F5438 microcontroller to control the collection of sensor data. The temperature sensor uses DS18B20 to realize the temperature data acquisition, and the vibration sensor uses ADXL345 to realize the vibration data acquisition. The wireless transmitting part uses CC2530 to realize the transmission of sensing data. The software language programming part uses the matching IAR platform to burn the program language. The final sensor node has been effectively tested in the laboratory environment and simulation real environment. The collected data truly reflect the environmental parameters, the overall power consumption is kept below 171.039mW, and the real-time transmission can be realized within the communication distance of 10 meters. The flexible installation requirements improve the system monitoring life and accuracy, and can effectively prevent the occurrence of failures.
