摘要：温度测量是工业、农业、国防和科研等部门最普遍的测量项目。它在工农生产、现代科学研究及高新技术开发过程中也是一个极其普遍而重要的测量参数。
温度测量在保证产品质量，提高生产效率，节约能源，安全生产，促进国民经济发展等诸多方面起到了至关重要的作用。对于一些对温度测量的精度有一定要求企业和单位来说，但如果直接去购买超高精度的温度测量仪器不仅是浪费资金，更是没有必要。所以研制和开发具有一定高精度的温度测量仪是非常有必要的。运用铂电阻和单片机来开发高精度温度测量系统在国内也是有一些单位在研发，但各单位所能达到的测温精度却有很大的差异，毕竟用单片机来开发温度测量系统，对于硬件的设计和软件编程有很高的要求。可以说，真正通过铂电阻和单片机来实现一定的测温精度并作为一个产品推出的，在国内还是相当少的。本设计的温度测量系统，测量精度可达到0.03℃，分辨率为0.001℃，可以说在国内同类产品中很少能达到这样的要求，有很好的市场价值。

Abstract:Temperature measurement is the universal subject for industry, agriculture, Ministry of Defense, scientific research and so on. It’s also a universal and important testing parameter in the development of agriculture, modern scientific research and high and new technology. Temperature measurement plays a very important role in many aspects such as: quality assurances boost productivity, energy conservation, safety in production, promote state economic development. As to some enterprise and public institution who have certain requires for accuracy of temperature measurement, it’s nonsense and waste money to buy the high accuracy temperature measurement equipment. So is necessarily to research and develop the high quality temperature measuring set. There are some institutions in home using platinum resistor and singlechip (MCM) to research and develop high precision temperature measurement system. As the requires for hardware design and software assembler is very high, the precision result differ much. In fact there are few product that use platinum resistor and singlechip (MCM) to control ( reach) accuracy. This design for temperature measurement system is rather advance, the precision can reaches to 0.03℃, resolving capability: 0.001℃.
