| 毕业设计 SWC单片机多点温度巡检系统，共32页，14734字，附源程序 摘要 仪器的智能化作为技术改造和技术发展的重要手段，在我国各个领域得到了广泛的应用，其产品已走进寻常百姓家庭。 高科技的发展，新的器件层出不穷，其中以单片机为核心控制部件的应用最为广泛，技术最为成熟，在一般的应用场合中，它完全能够满足系统的需要。 现代工业中生产中，很多产品对温度的控制要求比较高，而且需要对多个点进行监控，温度巡检系统也相应而生。在本设计（温度巡检系统）中，检测对象为多点温度，为一循环多点检测系统，以单片机为核心，它肩负着重要的任务，起到了检测、计算、输出信息（显示、记录等）等作用，以完成智能检测的目的。并且适用于各行业多点测温场合，能定时自动采集数据并打印记录或者手动打印存储在EEPROM中的记录。 The instrument intellectualization took the technological transformations and the technological development important method, obtained the widespread application in our country each domain, its product entered the common people family. The high tech development, the new component emerges one after another incessantly, take monolithic integrated circuit as core control portion application most widespread, the technology is matures, in the general application situation, it definitely can satisfy the system the need. Modern industry Mesozoic mid-production, very many products the control request quite are high to the temperature, moreover needs to carry on the monitoring to many spots, the temperature inspects the system also correspondingly to live. (Temperature inspects system) in this design center, the examination object for the multi-spots temperature, is as soon as circulates the multi- spots examination system, take the monolithic integrated circuit as the core, it is shouldering the vital duty, played the examination, the computation, the output information (demonstration, record and so on) and so on the role, completed the intelligent examination the goal. And is suitable to various professions multi- spots measured the warm situation, can fixed time the automatic gathering data and prints the record or the manual printing saves in EEPROM the record. 关键字：AT89C51 数字式测试传感器DS18B20 温度多路巡检 温度采集 授时 目录 前言 1 目录 2 摘要 3 第一章.AT89C51单片机性能介绍 4 1.主要特性 4 2.管脚说明 4 3.振荡器特性 6 4.芯片擦除 6 第二章.DS18B20 7 1.SWC数字温度传感器 7 2.DS18B20一线总线数字式传感器 8 3.第二种采集和处理程序 15 第三章.光电耦合器部分 21 1.光电耦合器 21 2.光电隔离抗干扰技术及应用 21 第四章.数码管驱动部分 24 1.译码器 24 2.七段数码管 26 3.七段译码驱动器74HC4511 27 4.双4选1开关74HC4052 27 第五章.电路图及元件明细表 28 1.DS18B20单片机多点温度巡检系统电路图 28 2.元件明细表及成本分析 28 第六章.DS18B20单片机多点温度巡检系统程序 29 第七章 参考文献 31 结束语 32 |
