智能建筑中嵌入式恒温控制系统设计

Design of embedded constant temperature control system in intelligent building

传统系统对恒温进行控制的效果较差,提出设计一种智能建筑中嵌入式恒温控制系统。在智能建筑中,以建筑物为研究对象,利用嵌入式技术设计系统总体结构框图;在硬件部分,针对恒温箱输出控制模块,利用珀尔贴(Peltier)效应设计热电偶闭合回路,并对半导体制冷器件驱动进行选取。在软件部分,建立交叉编译环境、移植嵌入式内核、设定恒温控制模糊规则;通过实验验证该系统设计的有效性。由实验结果可知,该系统恒温控制效果较好。

The traditional system has a poor control effect on the constant temperature,and puts forward the design of the embedded constant temperature control system in the intelligent building. In intelligent building,to the building as the research platform,the overall structure of the embedded technology to design the system diagram;in the part of hardware,the thermostat output control module,using the Perle post（Peltier）effect design of thermocouple closed loop,and the semiconductor refrigeration device driver selection. In the software part,we establish cross compilation environment,transplant embedded kernel,set constant temperature control fuzzy rule,and verify the effectiveness of the system design through experiments. The experimental results show that the system has good control effect at constant temperature.
