基于智能传感器的弹药库温/湿度监控系统设计

1 引言弹药从出厂到部队作战或训练使用以前主要存放在仓库中。在长期的储存过程中，弹药虽然处于宏观静止状态。但其质量不断发生变化。这是因为弹药主要由金属和装药组成．在长期储存过程中，由于温，湿度的影响。金属会锈蚀．从而使金属部件的强度降低。表面机械性能变坏，严重影响弹药的使用．甚至会造成重大事故。温，湿度还会使弹药装药的物理和化学性质发生变化．从而使其失去应有的战技要求。因此，温，湿度是弹药质量发生变化的主要矛盾。根据我军的仓库条件、我国的气候条件和目前仓库的管理水平．通常规定最高温度不超过30℃．最大湿度不超过。70％．即通常所说的“三七”线。传统弹药仓库的监控系统采用的是干，湿球湿度计、毛发湿度计、湿敏电阻器或由普通的温，

基于AT89C51的时间/位移换向控制器设计

引言　　在实际生产过程中，常常要用到具有自动换向功能的控制部件，如机械加工中的往返运行(位移)，直流电源的正反向输出，电动机的正反转运行等现象，都是当正向(或反向)运行到一定时间或一定位置时，自动换为反向(或正向)运行，周而复始的过程。实现这一过程的自动化，就是设计一套控制电路，再配以位移传感器或时间继电器。目前市场现有的时间继电器虽然可以用多个组合来满足一些使用场合的要求，但仍存在着重复计时误差大，稳定可靠运行性不高，使用不方便灵活等问题。为此，笔者研发了以单片机为核心组成的时间／位移换向控制器SWHX-1，该系统具有成本低等特点，可完全且克服以上不足。电路组成及工作原理　　SWHX-1的内部电路如图1所示。该系统分

AT89C51的串口和电脑的串口进行通信

串口通讯对单片机而言意义重大,不但可以实现将单片机的数据传输到电脑端,而且也能实现电脑对单片机的控制,比如你可以把写入单片机的数据码显示在电脑上,如可以使用一个按键,当按下它时使某一个字母如：AA,通过单片机的串口将它发送到电脑上显示,起到仿真器的某些功效,站长在开发数据采集设备时就是通过串口来检查数据正确与否的。 51单片机有一个全双工的串行通讯口,所以单片机和电脑之间可以方便地进行串口通讯。进行串行通讯时要满足一定的条件,比如电脑的串口是RS232电平的,而单片机的串口是TTL电平的,两者之间必须有一个电平转换电路,我们采用了专用芯片MAX232进行转换,虽然也可以用几个三极管进行模拟转换,但是还是用专用芯片更简单可靠。我

基于51单片机的自动温度测量报警系统设计

目前，无论是在工业生产中还是在科研实验中通过对温度测量来进行自动控制的设备越来越普及，应用场合也越来越多。随之而来的问题是，如何能够测得精确的温度以保证自动控制设备能够正确地发出控制指令来控制生产过程。另一方面，如果温度过高可能会对一些设备中的一些半导体元器件造成损坏。因此，对于自动高温报警的需求也在逐渐增加。本文基于以上方面的考虑，研究并设计了一种基于单片机的自动温度测量与报警系统。 1 系统硬件设计尽管目前市场上单片机的品种多样，功能也越来越多，但是受成本约束，性能优良的8位单片机仍然是工业检测与控制应用领域的首选。本系统就是以ATMEL公司的AT89C51单片机为中心，通过模数转换器AD7812对温度传感器的输

嵌入式频率计的设计

1 　引　言　　　　本频率计的设计以AT89C51单片机为核心，利用他内部的定时／计数器完成待测信号周期／频率的测量。单片机AT89C51内部具有2个16位定时／计数器，定时／计数器的工作可以由编程来实现定时、计数和产生计数溢出时中断要求的功能。在定时器工作方式下，在被测时间间隔内，每来一个机器周期，计数器自动加1（使用12 MHz时钟时，每1μs加1），这样以机器周期为基准可以用来测量时间间隔。在计数器工作方式下，加至外部引脚的待测信号发生从1到0的跳变时计数器加1，这样在计数闸门的控制下可以用来测量待测信号的频率。外部输入在每个机器周期被采样一次，这样检测一次从1到0的跳变至少需要2个机器周期（24个振荡周期），所
