摘要
采用ARM9内核芯片S3C2410为控制器,设计了一种嵌入式汽车空调温度控制系统,可实现现场显示、实时控制等功能。传感器使用了单总线数字式温度传感器DS18B20测量温度值。阐述了系统的构成原理和实现流程,重点介绍了系统的硬件结构。结合温度模糊控制算法,实验表明系统的硬件电路简单、控制精度好、可靠性高,且易于扩展。
The embedded systems are widely used in communications, domestic electric, auto electronics and other fields. This paper used the core chip S3C2410 of ARM9 as the controller, designed an embedded system of temperature control for automotive air-conditioning, which can realize the functions of spot display and real-time control. It used the 1-wire digital temperature sensor DS18B20 to measure the temperature. The system component principle and the flow realization was introduced, emphasized the hardware connection. With the algorithm of fuzzy control of the temperature, the experiment shows that this system has simple hardware circuit, high control accuracy, high reliability and expansibility.
