【摘要】：煤矿井下分站是煤矿监测监控系统的重要组成部分,是连接井下各数据采集模块与地面监控中心站之间数据传输的桥梁,承担了对井下各参数的采集以及实现分站和中心站之间所有数据的传输功能。分站是否能按设计要求准确无误的实现所有功能,决定了煤矿监测监控系统的工作效率,在煤矿安全管理工作中有着举足轻重的作用。在系统硬件设计阶段,分站主控芯片选用了基于ARM9的微处理器S3C2440,它优异的性能确保了分站的各项性能指标。丰富的接口资源和大容量的存储单元使得不需要添加外围设备就能满足传感器的多样化需求。在其他模块所用芯片的选择上也尽量遵循低功耗高性能的原则,并尽可能的控制系统中芯片的数量。通信单元中选用了DM9000网络芯片,它具有单芯片、高速度的特点,而且还可以实现自动调节使它的性能处于最佳状态,最难得的一点是能实现IEEE802.3x全双工控制,用户可以根据自己的需要很轻松的就能完成驱动程序的移植,并且在任何操作系统中这项工作都可以完成；在显示输入单元选用了带触摸功能的液晶显示器,集显示和输入功能于同一个界面上,更好地实现了人机交互,简化了系统操作还有效降低了功耗；用于数据采集的传感器选用了具有电流输出的红外传感器,它调校周期长、智能化程度高,节省人力的同时也提高了采集数据的可靠度。在软件设计阶段,介绍了软件设计思想,详细叙述了Linux在S3C2440上的移植和输入输出等设备在Linux的驱动程序设计。实现了分站对数据的采集以及分站和监控中心的数据通信,并且在分站和监控中心站的通信中引入了TCP/IP网络通信协议,确保了通信系统稳定性的同时还实现了资源共享。完成整个系统的设计和开发后,我们对系统做了多次实验与调试。实验结果表明分站能完成设计中的所有功能,在完成数据的采集和处理后最终能和监控中心站实现信息的传输,完全满足煤矿的实际要求。
[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.
