摘要
红外测温技术在生产过程,产品质量控制和监测,设备在线故障诊断和安全保护以及节约能源等方面发挥了着重要作用。它打破了传统的测温模式,并且具备回应速度快、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。
本设计利用SPCE061A单片机和TN9传感器实现了一个简单的红外测温仪。SPCE061A是台湾凌阳公司生产的十六位单片机,该单片机内置有2路DA转换,8路AD转换及在线仿真等丰富的功能,这为实现具备语音播报功能的红外测温计提供良好的方便条件。本系统主要包括SPCE061A单片机、TN9红外测温传感器、按键部分和音频输出电路等四部分。这样设计的结果使电路的结构合理,各种要求能基本保证,同时系统的稳定性得到提高。

ABSTRACT
The infrared temperature measurement technology plays an important role in the production process, the product quality control and the monitor, the equipment online breakdown diagnosis and the safe-keeping of security, as well as saved energy and so on. It broke the tradition measure pattern, and have many characteristics: quick response speed, high measuring accuracy, wide survey scope, and can simultaneously surveys the ambient temperature and the goal temperature, the survey distance amounts to 30 meters.
This design adopts to the SPCE061A single-chip and the TN9 sensor which bring about a simple infrared thermo-detector. SPCE061A is a 16 monolithic single- chip which produced by Ling Yang Science and pany. In this single-chip sets two road DA transformation, eight road AD transformation, and the online simulation and so on. This has provides a convenient condition for the infrared thermo -detector which has the r pronunciation broadcast function. The system includes: SPCE061A, TN9 infrared temperature sensor, Keys and audio output part and so on. This precisely designing causes the electric circuit structure to be reasonable, pletely guaranteeing each kind of requirement, at the same time obtaining the system stability .
