摘要:当今的信息通讯领域,无线以其便捷快速的优势,已经开始渐渐的取代有线,成为信息工程研究的一个重要的目标。随着无线传感器网络技术的发展,用于设计无线网络的网络协议也逐渐地多元化,无线局域网(WLAN)、蓝牙(BlueTooth)技术、无线保真(WiFi)、超宽带(UWB)以及Zigbee技术等技术相继出现,均展现出各自的应用特点和市场潜力。无线传感器网络技术也因此逐渐的受到了我们的关注。27817
另一方面,在科学技术地不断发展的推动下,红外热成像测温技术也得到了很大发展。红外热成像测温系统是一种的热图像成像和温度测温装置,利用目标与环境之间热对比度不同,把红外辐射能量密度的分布探测出来,然后显示在屏幕上,成为“热像”,再根据获取的灰度图像的灰度值,显示出该处对应的温度。
本毕业论文研究了无线测温以及红外热成像测温技术的原理和方法,结合这两种技术的特点,设计出了一种基于红外成像测温技术的无线测温系统。

Abstract:In today's society it is a mainstream trend that wired replaced by wireless in the field of information and communication, transfer information in a convenient and rapid way has become an important research goal of information engineering. With the development of wireless, the wireless network used to design protocol also gradually persified, such as wireless local area network (WLAN), BlueTooth (BlueTooth) technology, wireless fidelity (wi-fi), ultra wideband (UWB) and successive Zigbee technology, they both show their application characteristics and market potential. In this way, the wireless sensor network technology approaches into our field of vision.
On the other hand, under the impetus of the development in science and technology, the infrared thermal imaging temperature measurement technology has also obtained great development. Infrared thermal imaging temperature measurement system is a kind of thermal imaging and temperature measuring device, image by using the thermal contrast between target and environment is different, the infrared radiation energy density distribution of detection, then displayed on the screen, become the "hot", again according to get gray image grey value, the corresponding temperature showed here.
This paper studied the wireless temperature measurement and the principle and method of infrared thermal imaging temperature measurement technology, combining the two technologies, a general planning of wireless temperature measuring system was proposed based on infrared imaging temperature measurement technology.
Key words: infrared imaging, wireless temperature measurement and zigbee
