In detail , the embedded pc technology will be used in the system using in temperature control system , design hardware and software to the appointed control equipment , which make for setting up the excellent property control system of intelligent appearance ; the object controlled will be set up mathematical modeling and analyzed temperature field , which is in favor of the optimizing design of temperature control system ; the research of control arithmetic is based on the object controlled behavior analysis . the paper will analyze the control arithmetic mostly used in temperature control and use modified fuzzy control method based on rules into temperature control system , and gets relatively perfectly control effects . so it prove tha t it is feasible that using fuzzy control method realizes temperature control system 系统采用了现在用在温控系统中还很少的嵌入式pc技术，并结合具体的控制装置进行了硬件和软件设计，这有利于构建更高性能的智能仪表化控制系统；对被控对象进行了数学建模及温度场的分析，这为温控系统的优化设计提供了帮助；在对被控对象特性分析的基础上进行了控制算法的研究，将基于规则修改的模糊控制方法用于温度控制系统，得到了比较好的控制效果，由此，在温度快速变化的系统中采用模糊控制技术是一个比较好的选择。
