【摘要】：近些年來礦山安全事故的頻繁發(fā)生，造成巨大的經(jīng)濟(jì)損失和人員傷亡。礦山監(jiān)測系統(tǒng)作為能夠預(yù)知和預(yù)防礦山事故的系統(tǒng)。它的發(fā)展受到政府的高度重視。設(shè)計(jì)一種安全可靠的礦山無線監(jiān)測系統(tǒng)，不僅有助于減少礦山事故發(fā)生，而且有利于礦山安全事故防治系統(tǒng)的信息化、智能化和現(xiàn)代化。 本文通過對TinyOS操作系統(tǒng)進(jìn)行研究與改進(jìn)解決礦山無線監(jiān)測系統(tǒng)存在的以下問題。首先，針對目前國內(nèi)礦山監(jiān)測系統(tǒng)采用光纖或網(wǎng)線的有線通信方式造成系統(tǒng)末端部署靈活性低，，無法動(dòng)態(tài)監(jiān)測移動(dòng)目標(biāo)和成本高的問題，提出無線傳感器網(wǎng)絡(luò)和光纖環(huán)網(wǎng)結(jié)合方式。其次，由于礦山監(jiān)測系統(tǒng)向高集成化和自動(dòng)化發(fā)展造成系統(tǒng)任務(wù)并發(fā)頻繁，任務(wù)調(diào)度失敗率高，易堵塞和實(shí)時(shí)性低問題，本文提出在TinyOS操作系統(tǒng)中設(shè)計(jì)動(dòng)態(tài)任務(wù)的雙環(huán)自適應(yīng)任務(wù)調(diào)度算法來解決，該算法1400個(gè)網(wǎng)絡(luò)節(jié)點(diǎn)在1000s內(nèi)，系統(tǒng)丟包率為1.3%，任務(wù)調(diào)度失敗率維持在10%以內(nèi)。再次，針對視頻，語音和圖像等大量數(shù)據(jù)無線傳輸存在傳輸效率低和誤碼率高的問題，提出在TinyOS操作系統(tǒng)中設(shè)計(jì)報(bào)頭壓縮方案來濾除冗余報(bào)頭信，提高數(shù)據(jù)傳輸率和降低網(wǎng)絡(luò)功耗。該方案在127節(jié)點(diǎn)分為4組的系統(tǒng)中，壓縮效率達(dá)到50%左右。最后，為測試改進(jìn)的TinyOS系統(tǒng)移植完整性，節(jié)點(diǎn)存儲(chǔ)空間和節(jié)點(diǎn)能耗的變化,動(dòng)態(tài)任務(wù)的雙環(huán)自適應(yīng)任務(wù)調(diào)度算法應(yīng)用效果，報(bào)頭壓縮方案應(yīng)用效果，設(shè)計(jì)礦山無線網(wǎng)絡(luò)監(jiān)測系統(tǒng)的測試平臺(tái)。 測試和仿真結(jié)果表明，改進(jìn)后的TinyOS操作系統(tǒng)有效地提高礦山無線監(jiān)測系統(tǒng)的無線數(shù)據(jù)傳輸效率，降低網(wǎng)絡(luò)節(jié)點(diǎn)能耗，數(shù)據(jù)傳輸可靠性和解決任務(wù)頻繁并發(fā)造成網(wǎng)絡(luò)堵塞問題。
[Abstract]:In recent years, mine safety accidents occur frequently, resulting in huge economic losses and casualties. Mine monitoring system is a system that can predict and prevent mine accidents. Its development is highly valued by the government. The design of a safe and reliable mine wireless monitoring system is not only helpful to reduce the occurrence of mine accidents, but also conducive to the information, intelligence and modernization of mine safety accident prevention and control system. In this paper, the TinyOS operating system is studied and improved to solve the following problems in mine wireless monitoring system. First of all, aiming at the problem that the domestic mine monitoring system adopts the cable communication mode of optical fiber or network cable, the flexibility of the system terminal deployment is low, and the moving target can not be dynamically monitored and the cost is high. The combination of wireless sensor network and fiber optic ring network is proposed. Secondly, due to the development of mine monitoring system to high integration and automation, the system tasks are concurrent frequently, the failure rate of task scheduling is high, the problem is easy to jam and the problem of low real-time performance. In this paper, a dual-loop adaptive task scheduling algorithm for dynamic tasks in TinyOS operating system is proposed. In this algorithm, the packet loss rate of the system is 1.3 and the failure rate of task scheduling is less than 10% within 1000s of 1 400 network nodes. Thirdly, aiming at the problems of low transmission efficiency and high bit error rate in wireless transmission of a large number of data, such as video, voice and image, a header compression scheme is proposed in TinyOS operating system to filter redundant header letters. Improve data transmission rate and reduce network power consumption. In the system with 127 nodes divided into 4 groups, the compression efficiency is about 50%. Finally, in order to test the transplant integrity of the improved TinyOS system, the change of node storage space and node energy consumption, the application effect of dual-loop adaptive task scheduling algorithm for dynamic tasks and the application effect of header compression scheme are presented. The test platform of mine wireless network monitoring system is designed. The test and simulation results show that the improved TinyOS operating system can effectively improve the wireless data transmission efficiency of the mine wireless monitoring system reduce the energy consumption of network nodes data transmission reliability and solve the problem of network congestion caused by frequent concurrent tasks.
