1、河南理工大学毕业设计说明书摘要随着IT时代的到来,像计算机中心、设备间、配线室、基站等这些机房重地,我们必须为诸如供配电、UPS、空调、温湿度、漏水、消防、保安等设备提供正常的运行环境,否则,就会影响到整个系统的运行。机房温度检测部分的设计目的是为了保障中心机房重要系统的正常运行,实时监测机房环境温度过高或过低等紧急意外情况,并且能够及时记录、查询和显示。本文的硬件设计思路如下:采用AD590集成温度传感器检测机房温度,输出的温度模拟信号经过由ICL7650构成的测量放大电路进行模拟放大,选用CD4051作为多路选择模拟开关,并且经CD4040进行分频,再经过由ICL7135进行模数转换后
2、输入单片机主控芯片AT89C52,输出的温度信号用3位LED动态显示,而输入设备选用4*4矩阵式键盘,单片机输出的温度信号经由DAC7611构成的数模转换电路转换成模拟信号,再经过OP-07进行模拟放大保持,而单片机与计算机之间的串行通信通过MAX232来实现。本文还对每一个硬件单元电路进行了相对应的软件框图设计,并且加入了相应的程序。关键词:机房温度检测;传感器;单片机47河南理工大学毕业设计说明书TheDesignoftheDetectionPartoftheEngineRoomMonitoringSystemAbstractsWiththecomingofIT,asthecomput
