【摘要】：煤礦安全監(jiān)測系統(tǒng)是煤礦實際生產(chǎn)中不可或缺的部分，目前主要的監(jiān)測對象是環(huán)境安全監(jiān)測和生產(chǎn)工藝監(jiān)測，對電氣設(shè)備溫度、電纜接頭溫度的監(jiān)測通常是煤礦安全監(jiān)測系統(tǒng)的弱點甚至是盲點。由于礦用設(shè)備老化、負荷過大等現(xiàn)象都可能引起設(shè)備溫度過高、進而引發(fā)火災、爆炸現(xiàn)象，不僅嚴重影響煤礦的安全生產(chǎn)，而且威脅著作業(yè)人員的生命安全、還會給國家造成巨大的經(jīng)濟損失。因此，對煤礦井下設(shè)備溫度進行實時監(jiān)測并進行預警研究是很有必要的，本文使用傳感器技術(shù)、無線通信技術(shù)結(jié)合有線傳輸技術(shù)，，設(shè)計了一套監(jiān)測系統(tǒng)來對設(shè)備溫度進行實時遠程監(jiān)控，同時可實現(xiàn)設(shè)備監(jiān)測溫度的數(shù)據(jù)存儲分析和預測預警。 設(shè)備溫度監(jiān)測系統(tǒng)由終端節(jié)點模塊、數(shù)據(jù)傳輸網(wǎng)絡和上位機三部分組成。其中終端節(jié)點主要用于對設(shè)備溫度的采集、顯示并對超過閾值的溫度進行控制報警，STM32處理器作為主控器，匯聚各單節(jié)點的信息，并接收上位機的控制命令發(fā)送給終端節(jié)點。數(shù)據(jù)傳輸網(wǎng)絡主要用于上位機監(jiān)控中心與各終端節(jié)點的信息傳輸，采用兩級網(wǎng)絡的形式進行組網(wǎng)通信，各終端節(jié)點與主控器使用CC2530無線收發(fā)模塊實現(xiàn)ZigBee組網(wǎng)，主控器與監(jiān)控中心使用CAN總線來連接。上位機可以將CAN總線傳輸?shù)臄?shù)據(jù)進行顯示、保存，并通過BP神經(jīng)網(wǎng)絡對數(shù)據(jù)進行訓練進而預測設(shè)備溫度時間序列的變化趨勢。 系統(tǒng)通過在狹長的走廊模擬煤礦巷道進行實驗。結(jié)果顯示CC2530模塊組網(wǎng)穩(wěn)定，CAN總線數(shù)據(jù)傳輸準確可靠，系統(tǒng)實現(xiàn)了遠程監(jiān)測效果，找到設(shè)備溫度變化的內(nèi)在聯(lián)系，進而預測出設(shè)備溫度的未來變化，及時發(fā)現(xiàn)設(shè)備隱患，保障了煤礦的安全生產(chǎn)。
[Abstract]:The coal mine safety monitoring system is an indispensable part in the actual production of coal mines. At present, the main monitoring objects are environmental safety monitoring and production process monitoring, and the temperature of electrical equipment. Cable joint temperature monitoring is usually the weakness or even blind spot of coal mine safety monitoring system. Due to the aging of mine equipment and excessive load, the equipment temperature may be too high, which will lead to the phenomenon of fire and explosion, which will not only seriously affect the safety of coal mine production, but also threaten the safety of workers. It will also cause huge economic losses to the country. Therefore, it is necessary to carry out real-time monitoring and early warning research on the temperature of underground equipment in coal mines. In this paper, sensor technology, wireless communication technology and wired transmission technology are used. A set of monitoring system is designed to monitor the temperature of the equipment in real time and remote. At the same time, it can realize the data storage, analysis and forecast and early warning of the temperature of the equipment. The equipment temperature monitoring system consists of terminal node module, data transmission network and upper computer. The terminal node is mainly used to collect the temperature of the equipment, display and control the temperature beyond the threshold as the main controller, gather the information of each single node, and receive the control command from the host computer to the terminal node. The data transmission network is mainly used for the information transmission between the host computer monitoring center and the terminal nodes. The network communication is carried out in the form of two-level network. The terminal nodes and the master controller use the CC2530 wireless transceiver module to realize the ZigBee network. The main controller is connected to the monitoring center using the CAN bus. The host computer can display and save the data transmitted by CAN bus and train the data through BP neural network to predict the change trend of equipment temperature time series. The system simulates the coal mine roadway in the long and narrow corridor to carry on the experiment. The results show that the data transmission of can bus is accurate and reliable, the system realizes the effect of remote monitoring, finds the internal relation of the temperature change of the equipment, then predicts the future change of the temperature of the equipment, and finds out the hidden trouble of the equipment in time. To ensure the safety of coal production.
