多功能自行车里程表设计
该设计以AT89S52单片机为核心，霍尔传感器测车速，实现对自行车里程、速度、时间、温度的测量统计，采用存储器24C32实现在系统掉电的时候保存里程信息，并能将自行车的里程及速度用LCD实时显示。文章详细介绍了自行车测速仪的硬件电路和软件设计。硬件部分利用霍尔元件将自行车每转一圈的脉冲数传入单片机系统，然后单片机系统将信号经过处理送LCD显示。软件部分用C语言进行编程，采用模块化设计思想。该系统硬件电路简单，子程序具有通用性，完全符合设计要求。

说明： 按照通常的应用顺序，处理地震数据包括三个主要步骤-去卷积，叠加和偏移。表示处理坐标（中点，偏移和时间）中的地震数据量。去卷积沿时间轴起作用。它从记录的地震迹线中删除了基本地震子波（通过地球和记录系统的各种作用修改的源时间函数），从而提高了时间分辨率。去卷积通过压缩小波来实现此目标。堆叠也是压缩的过程（速度分析和静校正（）。特别是，首先通过对每个CMP道集的迹线应用常规偏移校正（速度分析和静态校正），将数据量减少到零偏移的中点时间平面（棱镜的正面）。 ，然后沿偏移轴求和。结果是一个堆叠的部分。(Generally, seismic data processing includes three steps: deconvolution and migration. Represents the amount of seismic data in processing coordinates (midpoint, offset, and time). Deconvolution works along the time axis. It removes the basic seismic wavelet (the source time function modified by various actions of the earth and the recording system) from the recorded seismic traces, thus improving the time resolution. Deconvolution achieves this goal by compressing wavelet. Stacking is also a process of compression (velocity analysis and statics). In particular, by applying conventional offset correction (velocity analysis and static correction) to the trace of each CMP gather, the amount of data is reduced to the midpoint time plane of zero offset (the front of the prism). And then sum along the offset axis.)
