【摘要】：我國(guó)煤炭資源豐富,煤炭行業(yè)正處于快速發(fā)展時(shí)期。但是由于煤礦處于地面表層之下,地下環(huán)境惡劣,開(kāi)采工作區(qū)地點(diǎn)分散,巷道狹窄并且巷道及工作區(qū)內(nèi)充斥著大量的對(duì)人體有毒的氣體,這些不利的地理環(huán)境很容易引發(fā)煤礦安全事故。為了減少安全事故的所帶來(lái)的損失,在做好礦難預(yù)防措施的同時(shí),當(dāng)?shù)V難發(fā)生之后,如何快速有效地開(kāi)展救援工作也是當(dāng)前要解決的一個(gè)重要的問(wèn)題。 為了有效地展開(kāi)煤礦井下的救援工作,本文提出了基于Mesh網(wǎng)絡(luò)的煤礦井下可視化應(yīng)急救災(zāi)通訊系統(tǒng)。該可視化救援系統(tǒng)主要由視頻監(jiān)控系統(tǒng)、人員定位系統(tǒng)、語(yǔ)音調(diào)度系統(tǒng)和多參數(shù)環(huán)境監(jiān)控系統(tǒng)組成。它們?cè)贛esh網(wǎng)絡(luò)的基礎(chǔ)上,充分利用Mesh網(wǎng)絡(luò)所提供的網(wǎng)絡(luò)資源,相互兼容與配合構(gòu)成了基于可視化通訊系統(tǒng),為救援工作的展開(kāi)提供了幫助。 在論述了煤礦井下巷道環(huán)境和當(dāng)前礦井下無(wú)線(xiàn)通信的基礎(chǔ)上,提出了以Mesh網(wǎng)絡(luò)為骨干網(wǎng)的無(wú)線(xiàn)可視化應(yīng)急救災(zāi)通訊系統(tǒng)。在實(shí)際環(huán)境中搭建了15km的線(xiàn)性Mesh網(wǎng)絡(luò)來(lái)測(cè)量網(wǎng)絡(luò)的整體性能并提出了優(yōu)化的方案。完成了對(duì)Mesh網(wǎng)絡(luò)各項(xiàng)性能的優(yōu)化后,為后續(xù)定位以及多參數(shù)檢測(cè)系統(tǒng)的接入做好了準(zhǔn)備。 首先,本論文重點(diǎn)分析了目前煤礦井下人員定位技術(shù)以及定位開(kāi)發(fā)平臺(tái)的優(yōu)缺點(diǎn),設(shè)計(jì)了基于Android平臺(tái)的人員定位系統(tǒng)。利用eSuperEditor繪圖軟件根據(jù)實(shí)際的礦井地圖來(lái)完成電子地圖的制作。在礦井電子地圖的基礎(chǔ)上,采用eSuperMap提供的SDK來(lái)實(shí)現(xiàn)定位系統(tǒng)軟件的編寫(xiě),并在實(shí)驗(yàn)室走廊環(huán)境下測(cè)試了定位軟件的定位精度。 其次,設(shè)計(jì)了以CD10環(huán)境監(jiān)控終端為下位機(jī)的基于Mesh的多參數(shù)環(huán)境監(jiān)控系統(tǒng),實(shí)現(xiàn)對(duì)煤礦井下的多種氣體的檢測(cè),控制指揮中心根據(jù)所返回的環(huán)境數(shù)據(jù)來(lái)判斷當(dāng)前區(qū)域是否適合救援工作的展開(kāi),為人員調(diào)度提供了一個(gè)有力的依據(jù)。 同時(shí),為確保低帶寬條件下調(diào)度工作的正常進(jìn)行,在Mesh網(wǎng)絡(luò)的基礎(chǔ)上開(kāi)發(fā)了短消息分發(fā)平臺(tái)。該平臺(tái)主要用來(lái)在帶寬較低的情況下實(shí)現(xiàn)人員之間的相互通信,確保了在Mesh網(wǎng)絡(luò)容量低的情況下人員的調(diào)度工作可以正常開(kāi)展。最后,在Mesh網(wǎng)絡(luò)下測(cè)試了所開(kāi)發(fā)的人員定位系統(tǒng),多參數(shù)監(jiān)控系統(tǒng)以及多消息分發(fā)系統(tǒng),確保這些系統(tǒng)可以在Mesh網(wǎng)絡(luò)下可以正常工作并和其它系統(tǒng)兼容。
[Abstract]:China is rich in coal resources and the coal industry is in a period of rapid development. The narrow roadway and the large amount of poisonous gas in the roadway and working area, these unfavorable geographical environment can easily lead to the coal mine safety accident, in order to reduce the damage caused by the safety accident, At the same time, how to carry out rescue work quickly and effectively is also an important problem to be solved. In order to effectively carry out the underground mine rescue work, this paper presents a visual emergency relief communication system based on Mesh network. The visual rescue system is mainly composed of video surveillance system and personnel positioning system. Based on the Mesh network, they make full use of the network resources provided by the Mesh network and are compatible and cooperate with each other to form a visual communication system. It is helpful for the rescue work. Based on the discussion of underground roadway environment and wireless communication under coal mine, A wireless visual emergency response communication system based on Mesh network is proposed. The linear Mesh network of 15km is built in the actual environment to measure the overall performance of the network and an optimized scheme is put forward. All kinds of Mesh networks are completed. After optimizing the performance of the. It is prepared for the subsequent location and the access of the multi-parameter detection system. Firstly, this paper focuses on analyzing the advantages and disadvantages of the present positioning technology and development platform of underground personnel in coal mine. The personnel positioning system based on Android platform is designed. The electronic map is made by using eSuperEditor drawing software according to actual mine map. On the basis of mine electronic map, the SDK provided by eSuperMap is used to realize the writing of positioning system software. The positioning accuracy of the software is tested in the laboratory corridor environment. Secondly, a multi-parameter environment monitoring system based on Mesh is designed, which takes the CD10 environment monitoring terminal as the lower computer to realize the detection of many kinds of gas in the coal mine. The control and command center determines whether the current area is suitable for rescue work according to the returned environmental data, which provides a powerful basis for personnel scheduling. At the same time, in order to ensure the normal scheduling under the condition of low bandwidth, a short message distribution platform is developed on the basis of Mesh network, which is mainly used to realize the communication between people under the condition of low bandwidth. In the case of low capacity of Mesh network, the scheduling of personnel can be carried out normally. Finally, the personnel location system, multi-parameter monitoring system and multi-message distribution system are tested under the Mesh network. Ensure that these systems work properly on Mesh networks and are compatible with other systems.
