一种新型太阳能热水控制器的设计与实现

DESIGN AND IMPLEMENTATION OF A NEW SOLAR HOT WATER CONTROLLER

针对传统太阳能热水控制器交互性差、拓展性差等问题,利用Cortex-A9开发平台,结合Android系统的优势,研究并设计出了一种基于RS485总线结构的新型控制器,然后阐述了该控制器的硬件结构,完成了系统裁剪与驱动移植,并开发出基于Android系统的监控软件。该控制器具有功能丰富、交互界面友好、灵活、拓展性强的特点,实现了与服务器的远程数据传输。测试结果表明,该控制器运行稳定,可满足设计需求。

Traditional solar hot water controller has the problems of poor interactivity and high difficulty of expansion.In this paper,we achieved a new controller based on the RS485 bus structure by taking advantage of the Cortex-A9 development platform and Android system.The hardware structure of the controller has been set up with system cropping and driver porting functions.A monitoring software based on Android is developed.The controller has multifunction with friendly interactive interface,excellent flexibility and expansibility.It can realizing remote data transmission.The stability is also tested to meet the design requirements.
