山东科技大学硕士学位论文摘要 山东科技大学硕士学位论文 摘要 摘要 本论文对井下矿车速度测量的仪器设计和数据管理的实现方法进行了研究。矿车速 度的测量长期以来一直没有引起人们的重视，因为没有有效的测量和管理手段，对井下 矿车速度的监控一直处于真空状态。本测量记录分析仪的研制有效的解决了这一问题， 它把矿车速度的测量、超速报警、数据的保存和处理结合起来，井下工作人员能够按规 定速度操作矿车，地面管理人员能够对井下矿车的运行速度情况有详细的了解，方便了 管理。 论文中涉及到 4 个方面的内容：速度测量仪、数据记录仪、数据接收器和上位机软 件。速度测量仪用于测量矿车速度，采用单片机测频法，把速度信号转化为频率信号， 测量结果准确度高，性能稳定。传感器选用霍尔速度传感器，抗干扰能力强，特别适合 于井下多粉尘、强噪声的恶劣环境中。速度信息从井下到地面的传递采用数据记录仪为 媒介。在矿车工作的时间内，测量仪实时测量并显示矿车速度，当速度超过上限值后声 光报警，同时速度信息连同时间和日期信息一起由插拔式的数据记录仪记录。当矿车司 机交班时，矿车司机将数据记录仪带回地面，由地面数据接收器读取后传递给计算机。 计算机中的专用软件将采集的数据保存为数据库形式，并能够以表格或曲线的方式显示 在界面上。 关键词：霍尔传感器 频率测量 数据记录仪 移动存储 ABSTRACT For a long time, because there is no an effective means of measurement and management, the measurement of tramcar speed is ignored and the intendance and control over tramcar speed under the coal mine is in the state of vacuum. The instrument which is introduced in this paper can solve this problem effectively and it combines alarm, saving data and data manage with speed-measurement. Through the use of this instrument, not only the workers under the coal mine can operate tramcars on the appropriate speed, but also the ones on the ground can know the state of tramcars in detail so as to run them effective. There are particular descriptions in four aspects in this paper: speed-measure instrument, data recorder, data receiver and computer software. Speed-measure instrument which is used to measure tramcar speed, transforms the signal of speed into the signal of frequency by computer and it has high accuracy and stability. The sensor is hall sensor which has strong anti-jamming ability especially it is fit for environment full of a lot of power and strong noise. Because tramcar always changes its locality, it is difficulty to transmit information transmission between under the coal mine and on the ground through wire or wireless. Therefore data recorder is designed to complete this assignment. During tramcar is working, speed measuring instrument measure and display tramcar speed. Whe
