【摘要】：煤矿通信系统在井下安全生产中发挥着非常重要的作用。现有的通信系统存在诸多问题,例如实施难度大、信号传输有死角、功能单一,难以满足生产调度的需求,导致矿井事故时有发生。漏泄通信系统为煤矿井下通信提供了一个很好的解决方案,论文介绍了该漏泄通信系统的主要功能与基本原理,并结合目前国内外的研究现状,设计并实现了该系统中数据传输接口模块。 论文项目背景为“基于数据的控制、调度与故障诊断研究及其在煤矿信息化改造中的应用”。论文主要研究该系统中数据传输接口模块,数据传输接口模块是整个系统的关键部分,关系到煤矿漏泄通信系统的有效运行。论文主要工作如下： (1)给出了一种集成合路器于数据传输接口模块的方案。基地台发送的多路数字信号经过数传接口模块合路,可通过一根漏泄电缆传至井下,减少了井下漏泄电缆的使用数量,提高了系统的可靠性。 (2)设计了一种基于多路复用技术的数字合路器,并利用FPGA技术实现了合路器与基地台的通信协议以及相应的软硬件。数字合路器进行信号处理需要大量时序逻辑编程和触发器,选用Altera公司CycloneⅣ系列的芯片EP4CE6E22C8作为主控芯片,硬件电路设计包括信号接收模块、信号处理模块、信号发送模块以及其他辅助模块。软件选用了QuartusⅡ为开发平台实现多路复用功能,软件设计包括降频模块、UART串口模块、多路控制模块、FIF0存储模块以及多路选择模块。 (3)搭建了硬件电路测试环境,基于硬件调试软件获取芯片内部信号进行仿真,通过该环境下传输信号的采集与测试,验证了系统设计的有效性。 论文通过对数据传输接口模块的软硬件设计实现了信号的有效传输。经过多次调试,测试结果表明系统满足设计需求,具有较高的经济效益和推广价值。图51幅,表5个,参考文献53篇。
[Abstract]:Coal mine communication system plays a very important role in underground safety production. There are many problems in the existing communication system, such as the difficulty of implementation, the dead angle of signal transmission, the single function, which is difficult to meet the demand of production scheduling, which leads to the occurrence of mine accidents from time to time. The leakage communication system provides a good solution for mine underground communication. This paper introduces the main functions and basic principles of the leakage communication system, and combines the current research situation at home and abroad. The data transmission interface module in the system is designed and implemented. The background of this paper is data based control, scheduling and fault diagnosis and its application in coal mine information transformation. The data transmission interface module is the key part of the whole system, which is related to the effective operation of the coal mine leakage communication system. The main work of this paper is as follows: (1) A scheme of integrated combiner in data transmission interface module is presented. The multi-channel digital signal sent by the base station can be transmitted to the underground by a leakage cable through a digital interface module, which reduces the number of underground leakage cables and improves the reliability of the system. (2) A digital combiner based on multiplexing technology is designed, and the communication protocol and corresponding hardware and software between the combiner and the base station are realized by using FPGA technology. The signal processing of digital combiner needs a lot of sequential logic programming and flip-flop. The EP4CE6E22C8 chip of Cyclone 鈪，
