基于单片机的红外温度测量系统 摘要 红外测温技术在生产过程中的产品质量控制和监测、设备在线故障的诊断、设备安全保护以及节约能源等方面发挥着重要作用。温度在绝对零度以上的物体，都会因自身的分子运动而辐射出红外线。通过红外探测器将物体辐射的功率信号转换成电信号。红外检测器将吸收的辐射转化为热能，因此提高检测器的温度，并把温度变化数据转化成电子信号，放大显示出来。红外测温打破了传统的测温模式，并且具备远距离非接触式测量、回应速度快、测量精度高、测量范围广和可同时测量环境温度和目标温度的特点，测量距离可达30米左右。 单片机具有体积小、功能强、成本低、应用面广等优点，可以说，智能控制与自动控制的核心就是单片机单片机在检测和控制系统中得到广泛的应用,?温度则是系统常需要测量、控制和保持的一个量主要介绍了利用单片机实现温度控制系统的设计过程红外测温；TN9；单片机Infrared temperature-measuring in the process of product quality control and monitoring, equipment, equipment on-line fault diagnosis safety protection and energy saving etc plays a very important role. Temperature of objects above absolute zero, the molecules are due to their own movement, the infra-red radiation. Through the infrared detector we can change the power signals which objects radiate into electrical signals. Infrared detector will absorb the radiation into heat, thereby increasing the temperature detector, and temperature data into electronic signals, amplified displayed. Infrared temperature-measuring broke traditional temperature measurement model, and long-distance non-contact measurement, the response speed and high precision measurement, the measurement range and simultaneous measurement of environmental temperature and temperature characteristic, measurement target distance can reach 30 meters. SCM has small, strong function, low cost, application, advantages and intelligent control and automatic control of single-chip microcomputer in the core is, inspection and control system has been widely used in the system, the temperature is often need to measure and control and maintain a quantity. This paper introduced the use of single chip microcomputer temperature control system design process, and based on single-chip microcomputer control technology, the infrared temperature measurement system using a serial interface (SPI) interface of periphery of infrared temperature sensor TN series, signal measuring temperature measuring temperature and environmental temperature, the goa
