【摘要】：近年來,國內(nèi)煤礦事故發(fā)生越來越頻繁。煤礦事故多數(shù)發(fā)生于地下煤礦,旦發(fā)生事故,煤礦原有的通信系統(tǒng)將可能失效,這將極大地阻礙礦難發(fā)生后井下的救援工作。目前,我國井下應(yīng)急救災(zāi)通訊設(shè)備僅能提供語音或簡單數(shù)據(jù)信息,無法全面反映災(zāi)害區(qū)域的實際情況。另外,由于井下地理環(huán)境特殊,巷道錯綜復(fù)雜,使得礦井下通信以及發(fā)生煤礦事故后救援行動難以實現(xiàn)。同時,救援過程中極易發(fā)生各種次生災(zāi)害,對各種次生災(zāi)害的擔(dān)憂和無法準(zhǔn)確判斷往往會嚴(yán)重遲滯救援工作的開展。本文正是基于這樣的背景,依托于國家科技支撐計劃課題“基于Mesh網(wǎng)絡(luò)井下可視化無線救災(zāi)通訊技術(shù)與裝備”(2013BAK06B03),提出建立一套有效、可靠的井下無線應(yīng)急救災(zāi)通訊系統(tǒng),并完成了其中的環(huán)境參數(shù)監(jiān)測子系統(tǒng)終端和終端軟件的開發(fā)設(shè)計。 根據(jù)井下應(yīng)急救災(zāi)通訊系統(tǒng)的網(wǎng)絡(luò)需求,本文構(gòu)建了井下應(yīng)急救災(zāi)通訊系統(tǒng)無線Mesh網(wǎng)絡(luò)。提出了系統(tǒng)結(jié)構(gòu)設(shè)計框架。從主要特點和網(wǎng)絡(luò)結(jié)構(gòu)等方面描述了無線Mesh網(wǎng)絡(luò),通過比較無線Mesh網(wǎng)絡(luò)與其他無線網(wǎng)絡(luò)的性能特點,確定并選擇無線Mesh網(wǎng)絡(luò)作為井下無線應(yīng)急救災(zāi)通訊無線網(wǎng)絡(luò)。在此基礎(chǔ)上,對無線Mesh網(wǎng)絡(luò)的網(wǎng)絡(luò)結(jié)構(gòu)和網(wǎng)絡(luò)設(shè)備也進行了測試和分析,選擇了最合適的網(wǎng)絡(luò)結(jié)構(gòu)和網(wǎng)絡(luò)設(shè)備。 根據(jù)井下無線應(yīng)急救災(zāi)通信系統(tǒng)環(huán)境監(jiān)測子系統(tǒng)設(shè)計的功能需求,開發(fā)了環(huán)境監(jiān)測子系統(tǒng)終端,為了環(huán)境監(jiān)測子系統(tǒng)的終端開發(fā)選擇了嵌入式開發(fā)系統(tǒng)作為開發(fā)的系統(tǒng),ARM處理器作為嵌入式硬件平臺,Linux作為開發(fā)的操作系統(tǒng)。采用多線程的方式構(gòu)建了終端平臺,完成了終端環(huán)境參數(shù)采集和閾值報警功能。 根據(jù)控制中心環(huán)境參數(shù)監(jiān)測軟件開發(fā)需求,在VC++6.0平臺上利用C++語言開發(fā)了“環(huán)境參數(shù)監(jiān)控系統(tǒng)”軟件和“環(huán)境參數(shù)監(jiān)控終端圖形化顯示及報警系統(tǒng)”軟件。對數(shù)據(jù)傳輸格式和通信協(xié)議進行了設(shè)計,完成了各個功能模塊的開發(fā),實現(xiàn)了在主控端對環(huán)境參數(shù)的監(jiān)控及圖形化顯示,同時還可以閾值報警。 本文最后進行了系統(tǒng)性能的綜合測試和性能分析。首先在大運河森林公園搭建測試環(huán)境,通過無線Mesh網(wǎng)絡(luò)的性能測試測試結(jié)果驗證了本文設(shè)計的無線Mesh網(wǎng)絡(luò)具有高吞吐量、時延低和場強高的特點；接著在校園內(nèi)搭建測試環(huán)境,通過環(huán)境參數(shù)監(jiān)測子系統(tǒng)性能測試也驗證了本文設(shè)計的環(huán)境監(jiān)測子系統(tǒng)完成了對數(shù)據(jù)的采集并存儲的功能,同時還可以圖形化顯示數(shù)據(jù)采集結(jié)果并且可以提供閾值預(yù)警功能。最終完成了井下環(huán)境參數(shù)監(jiān)測系統(tǒng)的開發(fā)。
[Abstract]:In recent years, coal mine accidents in China are more and more frequent. Most coal mine accidents occur in underground coal mines, but once accidents occur, the original communication system of coal mines may fail, which will greatly hinder the underground rescue work after the mine accident. At present, the underground emergency and disaster relief communication equipment in our country can only provide voice or simple data information, and can not reflect the actual situation in the disaster area. In addition, because of the special underground geographical environment and complicated roadway, it is difficult to realize the communication under mine and the rescue operation after coal mine accident. At the same time, all kinds of secondary disasters are easy to occur in the rescue process. Based on this background, this paper puts forward a set of effective and reliable underground wireless emergency disaster relief communication system based on Mesh network visualization wireless disaster relief communication technology and equipment (2013BAK06B03), which is supported by the National Science and Technology support Program. The development and design of the terminal and terminal software of environmental parameter monitoring subsystem are also completed. According to the network requirement of underground emergency communication system, this paper constructs the wireless Mesh network of underground emergency relief communication system. The design framework of the system structure is presented. This paper describes the wireless Mesh network in terms of its main characteristics and network structure. By comparing the performance of the wireless Mesh network with other wireless networks, the wireless Mesh network is determined and selected as the underground wireless emergency relief communication wireless network. On this basis, the network structure and network equipment of wireless Mesh network are also tested and analyzed, and the most suitable network structure and network equipment are selected. According to the functional requirement of environment monitoring subsystem design of underground wireless emergency disaster relief communication system, the terminal of environment monitoring subsystem is developed. For the terminal development of the environment monitoring subsystem, the embedded development system is selected as the system developed by arm processor as the embedded hardware platform and Linux as the operating system. The terminal platform is constructed by multithreading, and the terminal environment parameter collection and threshold alarm function are completed. According to the development requirement of environment parameter monitoring software in control center, the software of "environment parameter monitoring system" and "environmental parameter monitoring terminal graphical display and alarm system" are developed by using C language on the platform of VC 6.0. The data transmission format and communication protocol are designed, the development of each function module is completed, the monitoring and graphical display of environmental parameters are realized at the main control end, and the threshold alarm is also realized. Finally, the comprehensive test and performance analysis of the system performance are carried out. Firstly, the test environment is built in the Grand Canal Forest Park. The performance test results of wireless Mesh network verify that the wireless Mesh network designed in this paper has the characteristics of high throughput, low delay and high field strength. The performance test of the environment parameter monitoring subsystem also verifies that the environment monitoring subsystem designed in this paper has completed the function of collecting and storing the data, at the same time, it can display the data acquisition results graphically and provide the threshold warning function. Finally, the development of underground environmental parameter monitoring system is completed.
