智能体温测量仪设计与总结报告
全文38页 约20000字 讲述详细 图文并茂
一.摘要
本次设计的智能体温仪主要硬件部分由温度传感器、信号放大电路、A/D转换电路、CPU控制电路、存储器电路、液晶显示模块构成。温度传感器(PT100)每隔1秒钟便将测得的温度变化转化成电压信号后,经弱信号检测放大器进行放大,由A/D转换器转换成数字信号.,然后由单片机读取数字信号再进行温度数值转换,并转换为字符信号(ASCΙΙ码)送到LCD进行温度显示。当所测温度超出人体正常体温时便会发出报警信号,报警温度在程序内设置,并且可以通过单片机编程进行时间显示(该仪器附带时钟功能)。此外,电源的供电为常用的5V,±12V。
关键字:铂电阻,四线式接法,单片机,LCD显示器。
Abstract:
The hardware of this intellectualized thermometer of this design are as follows: the temperature transducer, signal magnifying circuit, A/D transition circuit, CPU controlling circuit, memorizer circuit and LCD module. The temperature transducer (PT100) measures the changes of temperature every second and transforms it into a voltage, after being it has been magnified by the signal magnifier, it will be transformed into digital signals by the A/D transition circuit. The SCM will read the digital signals and transform them back into a temperature in the form of character signal (ASCΙΙ code), and then shown it on the LCD screen. When the measured temperature is above the ordinary one of a human body, it will send out the alarming message. The alarming temperature is set within the program, and the time of it can be shown by the SCM through a certain program (this device contains a time function). And plus, the power supply should be the normal 5V, ±12V.
Keywords: PT-Transducer Four-wire-connection
SCM(Single Chip Micyoco) Liquid Crystal Display
