摘要
对于发电厂的一些重要电气设备，像高压开关柜、母线接头等由于运作时间较长，有些关键部位会出现老化及接触电阻过大的问题，进而逐渐发热且该温度不能够得到有效检查，其原因存在多种可能，目前最好的解决方法是通过非接触式的测温方法对其进行监测。本设计本着追求最低成本的原则，在保证仪器测量精度的前提下，开发了一套非接触式红外测温系统，对重要电气设备及其关键部位实时监测，设计中还对系统进行了大致架构。本文以红外测温原理为基础，设计了在强电强磁场环境下应用的红外测温系统，包括整体的设计方案、硬件电路设计，软件算法及流程，对系统的测试当中，调整其误差低于±0.2℃，提高了测量精度。主要介绍红外辐射原理，基于STC89C52和MLX0614中所包含的红外测温系统，对其工作原理做全面分析进而详细介绍该系统的设计与实现方法，介绍内容同时也包含测温系统相关使用要求在内。

Design of infrared temperature measurement system
Abstract
For some important electrical equipment in power plants, such as high-voltage switchgears, switchgears, bus connector, etc., during certain long-term operation, certain key parts of these devices will be heated due to aging or excessive contact resistance. The temperature of these heat-generating parts is usually not directly detectable for many reasons, and the best solution at present is to monitor it through non-contact temperature measurement methods. Based on the principle of pursuing the lowest cost, this design develops a non-contact infrared temperature measurement system under the premise of guaranteeing the measurement accuracy of the instrumentand monitors the important electrical equipment and its key parts in real time. In the design, the system is also roughly structured. According to the principle of infrared temperature measurement, an infrared temperature measurement system under strong magnetic field environment is designed, including overall design scheme, hardware circuit design, software algorithm and flow chart.During the system test, the error was adjusted to within ±0.2°C, improving the measurement accuracy. The principle of infrared radiation is mainly introduced. The working principle of infrared temperature measurement system based on STC89C52 and MLX90614 is introduced and this paper also explains the design and implementation of the system.The applicable conditions of the temperature measurement system are briefly introduced.
