基于单片机的红外测温仪设计

Design of Infrared Thermometer Based on Single-chip Microcomputer

设计以单片机作为整个测温仪的核心,结合A/D转换器、液晶显示器等外部设备,在软件设计和硬件设计的基础上,设计出一种拥有汉字显示逻辑判断等智能型电子测温计。它提供了一种新的温度测量方案,采用红外温度传感器来测量温度信号,可同时测量目标温度和环境温度,并将测量的数据经过放大器,转换器送给单片机处理,之后送数码管显示。红外测温打破了传统的测温模式,它响应快、测量精度高、可靠性高、范围广,为非接触测量,因而不易损坏。该温度计以准确快捷的测量功能、清晰易懂的数字化显示方便人们日常生活使用。

The article, which takes microcontroUer as the core of the thermometer, with A/D converter, LCD monitors and other external devices, based on software design and hardware design, designs an intelligent electronic thermometer with Chinese character display logic. It provides a new temperature measurement program, uses infrared temperature sensor to measure the temperature signal, which can measure the target temperature and ambient temperature at the same time, and send the measured data into the amplifiers, converters to give microcontroller processing, and then sent to digital display. The way of infrared temperature measuring breaks the traditional model, which has the advantages of fast response, high accuracy, high reliability and wide range of non-contact measurement, and thus not easily damaged. For its accurate and efficient measurements and clear digital display, the thermometer facilitates peoples daily lives.
