【摘要】：煤礦井下分站是煤礦監(jiān)測監(jiān)控系統(tǒng)的重要組成部分,是連接井下各數(shù)據(jù)采集模塊與地面監(jiān)控中心站之間數(shù)據(jù)傳輸?shù)臉蛄?承擔(dān)了對井下各參數(shù)的采集以及實現(xiàn)分站和中心站之間所有數(shù)據(jù)的傳輸功能。分站是否能按設(shè)計要求準(zhǔn)確無誤的實現(xiàn)所有功能,決定了煤礦監(jiān)測監(jiān)控系統(tǒng)的工作效率,在煤礦安全管理工作中有著舉足輕重的作用。 在系統(tǒng)硬件設(shè)計階段,分站主控芯片選用了基于ARM9的微處理器S3C2440,它優(yōu)異的性能確保了分站的各項性能指標(biāo)。豐富的接口資源和大容量的存儲單元使得不需要添加外圍設(shè)備就能滿足傳感器的多樣化需求。在其他模塊所用芯片的選擇上也盡量遵循低功耗高性能的原則,并盡可能的控制系統(tǒng)中芯片的數(shù)量。通信單元中選用了DM9000網(wǎng)絡(luò)芯片,它具有單芯片、高速度的特點,而且還可以實現(xiàn)自動調(diào)節(jié)使它的性能處于最佳狀態(tài),最難得的一點是能實現(xiàn)IEEE802.3x全雙工控制,用戶可以根據(jù)自己的需要很輕松的就能完成驅(qū)動程序的移植,并且在任何操作系統(tǒng)中這項工作都可以完成；在顯示輸入單元選用了帶觸摸功能的液晶顯示器,集顯示和輸入功能于同一個界面上,更好地實現(xiàn)了人機交互,簡化了系統(tǒng)操作還有效降低了功耗；用于數(shù)據(jù)采集的傳感器選用了具有電流輸出的紅外傳感器,它調(diào)校周期長、智能化程度高,節(jié)省人力的同時也提高了采集數(shù)據(jù)的可靠度。 在軟件設(shè)計階段,介紹了軟件設(shè)計思想,詳細(xì)敘述了Linux在S3C2440上的移植和輸入輸出等設(shè)備在Linux的驅(qū)動程序設(shè)計。實現(xiàn)了分站對數(shù)據(jù)的采集以及分站和監(jiān)控中心的數(shù)據(jù)通信,并且在分站和監(jiān)控中心站的通信中引入了TCP/IP網(wǎng)絡(luò)通信協(xié)議,確保了通信系統(tǒng)穩(wěn)定性的同時還實現(xiàn)了資源共享。 完成整個系統(tǒng)的設(shè)計和開發(fā)后,我們對系統(tǒng)做了多次實驗與調(diào)試。實驗結(jié)果表明分站能完成設(shè)計中的所有功能,在完成數(shù)據(jù)的采集和處理后最終能和監(jiān)控中心站實現(xiàn)信息的傳輸,完全滿足煤礦的實際要求。
[Abstract]:Coal mine sub-station is an important part of coal mine monitoring and monitoring system. It is a bridge between the data acquisition module and the ground monitoring center station. Undertake the acquisition of the parameters of the underground and the realization of all the data transmission function between the sub-station and the central station. Whether the sub-station can achieve all functions accurately according to the design requirements. It determines the working efficiency of coal mine monitoring and monitoring system and plays an important role in coal mine safety management. In the system hardware design stage, the sub-station main control chip selected the microprocessor S3C2440 based on ARM9. Its excellent performance ensures the performance of the sub-station. The rich interface resources and large storage units make it possible to meet the diverse needs of sensors without adding peripheral devices. The choice also follows the principle of low power and high performance. And the number of chips in the control system as far as possible. Communication unit selected the DM9000 network chip, it has the characteristics of single chip, high speed. It is also possible to achieve automatic regulation to make its performance in the best state, the most rare point is to achieve IEEE802.3x full duplex control. Users can easily complete the porting of drivers according to their own needs, and this work can be done in any operating system; The LCD with touch function is selected in the display input unit, which sets display and input functions on the same interface, realizes better man-machine interaction, simplifies system operation and effectively reduces power consumption. The infrared sensor with current output is selected for data acquisition. It has the advantages of long adjusting period, high intelligence, saving manpower and improving the reliability of the collected data. In the phase of software design, the idea of software design is introduced. In this paper, the driver design of Linux on S3C2440 and input / output devices in Linux is described in detail, and the data acquisition and data communication between sub-station and monitoring center are realized. The TCP/IP network communication protocol is introduced into the communication between the sub-station and the monitoring center station, which ensures the stability of the communication system and realizes the resource sharing at the same time. After completing the design and development of the whole system, we have done many experiments and debugging to the system. The experimental results show that the sub-station can complete all the functions in the design. After the data collection and processing is completed, the information transmission can be realized with the monitoring center station, which fully meets the actual requirements of the coal mine.
