【摘要】：我国是煤炭大国,同时煤炭也是我国主要的能源和重要化工原料,未来几十年里我国能源主要依靠煤炭的格局不会改变,但近年来,随着我国经济的快速发展,我国对煤炭能源的需求量也日益增大,由此带来的煤炭安全生产问题也日益凸显,现在高居不下的矿难事故已经成为煤矿安全生产的重大威胁,因此加强对煤矿井下生产环境的监测监控,切实保障煤矿井下生产的安全进行,对减少甚至避免井下安全事故的发生具有极其重要的意义。井下监控分站是煤矿井下安全监测监控系统的重要组成部分,它不仅要对其上面所配接的各路传感器进行数据采集和处理,还承担着与地面中心站进行数据交换的任务,因此监控分站是井下各传感监测模块与地面上位机中心站之间进行数据传输与通信的枢纽,监控分站能否有效可靠工作直接关系到整个煤矿井下监测监控系统工作能否顺利进行。本课题正是在这种背景下提出来的,论文中设计了一种煤矿井下监控分站,与上位机有RS485和FSK两种通讯方式,其主核芯片采用的是美国Silabs公司生产的高性能C8051F020单片机,分站监控容量很大,具有8路模拟量信号输入口,可以用来接收电流、频率等符合煤矿行业行业标准规定的多种信号制式传感器信息,具有8路开关量信号输入口,可以用来采集馈电状态、风筒开关、风门开关等信号,以此来监测煤矿井下各类电气设备的工作运转状态,1路报警输出口和4路控制量信号输出口用于越限报警和断电输出控制设备。本论文通过查阅研究相关国家标准和行业标准,明确了井下分站的功能需求,并根据功能需求确定了监控分站的总体设计方案,论文中所做的主要工作包括：设计并实现了分站的硬件电路,设计并完成了分站的软件设计和程序编写,制定了分站与上位机的通讯协议并实现了分站与上位机之间的通讯,进行了监测分站的硬件和软件整体联调试验。试验结果表明,本论文中设计的监控分站的各个功能模块均可以正常工作,分站的16个信号输入端口可以准确采集模拟量和开关量并将其送入到中央处理单元中进行数据分析和处理,并能在井下浓度超标或设备工作异常时报警断电,同时可以接收上位机的配置指令并与上位机进行数据通讯。由此可见,该分站的设计是合理并切合实际的。
[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.
