DSP数据采集论文：基于TCP-IP协议的通风机远程监控系统研究

1、dsp数据采集论文：基于tcp/ip协议的通风机远程监控系统研究【中文摘要】众所周知，近年来发生的重大煤矿事故大部分都是 由于瓦斯爆炸引起的。然而瓦斯的爆炸,与巷道里的通风是否顺畅， 风量大小与否都有着必然联系。对于煤矿巷道通风系统来说，它的关 键设备是通风机。通风机具有“矿井肺腑”之称。众多的煤矿事故给 我们敲响了警钟，在煤矿安全生产过程中，通风机运行的好与坏直接 关系到煤矿的安全生产和经济效益。因此，一个比较完善、操作方便 的控制系统对其运行过程进行监控变显十分重要，也是保障通风机安 全、可靠运行的最佳途径。我们必须对通风机的运行状况进行实吋监 控。本文研究的是地面的主扇通风机，其运行状态

2、直接影响整个生产 系统的正常运行和安全生产，一旦发生故障将造成巨大的停产损失和 安全问题。主扇通风机担负着向井下不断的输送新鲜空气、排岀粉尘 和污浊气流以及确保矿井生产安全的重任。据统计，煤矿事故70%以 上是由于通风设备故障、通风管理不善等所造成。另外，通风机多数 运行工况点偏离设计点，致使运行效率偏低。为此，必须对运行中的通 风机进行有效的监测和控制，对通风机的各个参数和运行的工况建立 一个完备的档案，为现场的管理和维护提供依据，以解决通风机运行 中的安全性和经济性问题。本监控系统就是在此背景下提出的。基于 tcp/ip协议的通风机远程监控系统能无间隔的进行设备运行状况监 视，具有超限控制

3、、报警等功能,提高了风机的自动化程度。本系统采 用基于tcp/ip的协议的以太网控制系统，有设备控制层和网络监管 层组成，采用vb6. 0编写上位机监控界面，实现dsp系统与pc机之间 通过以太网进行数据传输的具体过程。系统采用一种以dsp为核心的 新型数据采集系统，主要采集的数据有风机负压、入口负压、电机轴 承温度、电机绕组温度、电机垂直振动参数等。利用dsp数据采集系 统对各个主要参数进行高速实吋采集，由dsp完成对基本参数的测量, 计算与分析工作，并完成基于tcp/ip协议的以太网接入的dsp实现技 术。图表参【英文摘要】as we all know, a major coal mine
