【摘要】：鐵礦石是國家重要戰(zhàn)略資源,同時也是我國進口量最大的礦產(chǎn)資源。隨著鐵礦石貿(mào)易的發(fā)展和壯大,鐵礦石含鐵量的快速檢測技術也越來越被整個鋼鐵行業(yè)看重。鐵礦石的價格主要由鐵礦石的含鐵量和礦石中有害雜質(zhì)的含量來決定。然而,進口鐵礦石質(zhì)量堪憂,質(zhì)量安全問題頻發(fā)。這個現(xiàn)象也說明了鐵礦含鐵量現(xiàn)行檢測方法不能滿足鐵礦選礦加工、貿(mào)易銷售現(xiàn)場的實時和快速測試需要,因此高性能、智能化的檢測技術亟待開發(fā)。本文在研究了常用鐵礦含鐵量測量方法基礎上,結合嵌入式系統(tǒng)的相關技術,設計了一個磁鐵礦含鐵量快速實時測量系統(tǒng)。系統(tǒng)包括以電感傳感器為核心的信息采集模塊和以ARM7微處理器為核心的微處理模塊。論文探討了基于互感式電感傳感器的磁鐵礦含鐵量測量方法,研究了基于電磁感應互感效應的鐵礦含鐵量快速測試原理,設計了鐵礦含鐵量信息采集模塊,信號調(diào)理模塊等,構建了以ARM為核心的智能傳感器的信息控制系統(tǒng)。在實驗室條件下對系統(tǒng)進行調(diào)試運行,通過對實驗數(shù)據(jù)的處理,有效的論證的該系統(tǒng)的可行性。研制的互感式傳感器測量系統(tǒng)具有實時測量,操做方便,不受環(huán)境影響,易于攜帶等優(yōu)點;滿足鐵礦石選礦加工和銷售過程的快速測試要求,能有效提高鐵礦企業(yè)和鋼鐵企業(yè)的生產(chǎn)效率,促進整個行業(yè)的發(fā)展;具有一定的實用性和先進性,對提高我國鐵礦產(chǎn)業(yè)向著高效率、智能化的方向發(fā)展有著重要的現(xiàn)實意義。
[Abstract]:Iron ore is an important strategic resource of our country, and it is also the largest import mineral resource of our country. With the development and expansion of iron ore trade, the rapid detection technology of iron ore content is more and more valued by the whole iron and steel industry. The price of iron ore is mainly determined by the iron content of iron ore and the content of harmful impurities in the ore. However, the quality of imported iron ore is worrying, quality and safety problems occur frequently. This phenomenon also shows that the current detection method of iron content in iron ore can not meet the real-time and rapid testing needs of iron ore dressing processing and trade field. Therefore, the high-performance, intelligent detection technology needs to be developed urgently. In this paper, a fast and real-time measurement system for iron content of magnetite is designed on the basis of studying the common methods of iron content measurement in iron ore and combining with the related technology of embedded system. The system includes information acquisition module based on inductor sensor and micro-processing module based on ARM7 microprocessor. In this paper, the measurement method of iron content in magnetite based on mutual inductance sensor is discussed, and the principle of rapid measurement of iron content in iron ore based on electromagnetic induction mutual inductance effect is studied. The iron content information collection module and signal conditioning module are designed. The information control system of intelligent sensor based on ARM is constructed. The system is debugged and run under laboratory conditions. Through the processing of experimental data, the feasibility of the system is proved effectively. The self-developed mutual inductance sensor measurement system has the advantages of real-time measurement, convenient operation, not affected by the environment, easy to carry and so on. It can effectively improve the production efficiency of iron ore enterprises and iron and steel enterprises and promote the development of the whole industry in order to meet the requirements of rapid testing of iron ore processing and sales process. It is practical and advanced to improve the development of iron ore industry in China in the direction of high efficiency and intelligence.
