【摘要】：我國是煤炭大國,同時(shí)煤炭也是我國主要的能源和重要化工原料,未來幾十年里我國能源主要依靠煤炭的格局不會(huì)改變,但近年來,隨著我國經(jīng)濟(jì)的快速發(fā)展,我國對(duì)煤炭能源的需求量也日益增大,由此帶來的煤炭安全生產(chǎn)問題也日益凸顯,現(xiàn)在高居不下的礦難事故已經(jīng)成為煤礦安全生產(chǎn)的重大威脅,因此加強(qiáng)對(duì)煤礦井下生產(chǎn)環(huán)境的監(jiān)測(cè)監(jiān)控,切實(shí)保障煤礦井下生產(chǎn)的安全進(jìn)行,對(duì)減少甚至避免井下安全事故的發(fā)生具有極其重要的意義。井下監(jiān)控分站是煤礦井下安全監(jiān)測(cè)監(jiān)控系統(tǒng)的重要組成部分,它不僅要對(duì)其上面所配接的各路傳感器進(jìn)行數(shù)據(jù)采集和處理,還承擔(dān)著與地面中心站進(jìn)行數(shù)據(jù)交換的任務(wù),因此監(jiān)控分站是井下各傳感監(jiān)測(cè)模塊與地面上位機(jī)中心站之間進(jìn)行數(shù)據(jù)傳輸與通信的樞紐,監(jiān)控分站能否有效可靠工作直接關(guān)系到整個(gè)煤礦井下監(jiān)測(cè)監(jiān)控系統(tǒng)工作能否順利進(jìn)行。 本課題正是在這種背景下提出來的,論文中設(shè)計(jì)了一種煤礦井下監(jiān)控分站,與上位機(jī)有RS485和FSK兩種通訊方式,其主核芯片采用的是美國Silabs公司生產(chǎn)的高性能C8051F020單片機(jī),分站監(jiān)控容量很大,具有8路模擬量信號(hào)輸入口,可以用來接收電流、頻率等符合煤礦行業(yè)行業(yè)標(biāo)準(zhǔn)規(guī)定的多種信號(hào)制式傳感器信息,具有8路開關(guān)量信號(hào)輸入口,可以用來采集饋電狀態(tài)、風(fēng)筒開關(guān)、風(fēng)門開關(guān)等信號(hào),以此來監(jiān)測(cè)煤礦井下各類電氣設(shè)備的工作運(yùn)轉(zhuǎn)狀態(tài),1路報(bào)警輸出口和4路控制量信號(hào)輸出口用于越限報(bào)警和斷電輸出控制設(shè)備。 本論文通過查閱研究相關(guān)國家標(biāo)準(zhǔn)和行業(yè)標(biāo)準(zhǔn),明確了井下分站的功能需求,并根據(jù)功能需求確定了監(jiān)控分站的總體設(shè)計(jì)方案,論文中所做的主要工作包括：設(shè)計(jì)并實(shí)現(xiàn)了分站的硬件電路,設(shè)計(jì)并完成了分站的軟件設(shè)計(jì)和程序編寫,制定了分站與上位機(jī)的通訊協(xié)議并實(shí)現(xiàn)了分站與上位機(jī)之間的通訊,進(jìn)行了監(jiān)測(cè)分站的硬件和軟件整體聯(lián)調(diào)試驗(yàn)。試驗(yàn)結(jié)果表明,本論文中設(shè)計(jì)的監(jiān)控分站的各個(gè)功能模塊均可以正常工作,分站的16個(gè)信號(hào)輸入端口可以準(zhǔn)確采集模擬量和開關(guān)量并將其送入到中央處理單元中進(jìn)行數(shù)據(jù)分析和處理,并能在井下濃度超標(biāo)或設(shè)備工作異常時(shí)報(bào)警斷電,同時(shí)可以接收上位機(jī)的配置指令并與上位機(jī)進(jìn)行數(shù)據(jù)通訊。由此可見,該分站的設(shè)計(jì)是合理并切合實(shí)際的。
[Abstract]:China is a big coal country, and coal is also the main energy and important chemical raw material in our country. In the coming decades, the pattern of our country's energy mainly relying on coal will not change, but in recent years, with the rapid development of our country's economy, The demand for coal energy in our country is also increasing day by day, and the problem of coal safety production is also becoming more and more prominent. Now, the high mine accident has become a major threat to the safety of coal mine production. Therefore, to strengthen the monitoring and monitoring of the underground production environment of coal mines, and to ensure the safety of underground production in coal mines, It is of great significance to reduce or even avoid the occurrence of underground safety accidents. The underground monitoring sub-station is an important part of the underground safety monitoring and monitoring system. It not only collects and processes the data of the various sensors attached to it, but also undertakes the task of exchanging data with the ground central station. Therefore, the monitoring sub-station is the hub of data transmission and communication between the sensing monitoring module and the central station of the upper computer on the ground. Whether the monitoring sub-station can work effectively and reliably is directly related to whether the whole underground monitoring and monitoring system can be carried out smoothly. This subject is put forward under this background. In this paper, a kind of underground monitoring station in coal mine is designed. There are two communication modes of RS485 and FSK with the upper computer. The main core chip of this station is the high performance C8051F020 single chip computer produced by Silabs Company of USA, the main core chip of which is the high performance C8051F020 single chip microcomputer, which is produced by American Silabs Company. The monitoring capacity of the sub-station is very large, and it has 8 analog signal input ports, which can be used to receive multi-signal sensor information, such as current, frequency and so on, in accordance with the standards of the coal industry, and has eight switching signal input ports. It can be used to collect signals such as feed state, tuyere switch, wind valve switch, etc. In order to monitor the working condition of all kinds of electrical equipment in coal mine, one way alarm output outlet and four channel control signal output outlet are used for over-limit alarm and outage output control equipment. By consulting the relevant national standards and industry standards, this paper clarifies the functional requirements of underground sub-stations, and determines the overall design scheme of monitoring sub-stations according to the functional requirements. The main work of the thesis includes: designing and realizing the hardware circuit of the sub-station, designing and completing the software design and programming of the sub-station, establishing the communication protocol between the sub-station and the host computer, and realizing the communication between the sub-station and the host computer. The hardware and software of the monitoring sub-station are tested. The test results show that each functional module of the monitoring sub-station designed in this paper can work normally. The 16 signal input ports of the sub-station can accurately collect analog and switching signals and send them to the central processing unit for data analysis and processing, and can alarm power outages when the underground concentration exceeds the standard or the equipment is abnormal. At the same time, the configuration instructions of the upper computer can be received and the data communication between the upper computer and the upper computer can be carried out. Thus, the design of the sub-station is reasonable and practical.
