【摘要】：随着我国雾霾状况的日益恶化,当下粗放型经济发展模式的转型已迫在眉睫,低碳环保的电热膜供暖是替代传统的集中燃煤供暖的理想方案之一,更是减少因供暖因素导致的雾霾的一种可行方式。电热膜在外加电场的作用下,通过内部分子的布朗运动而产生热量,除了少部分流失外,绝大多数热量以辐射和对流的方式传递到房间中。本文以电热膜供暖系统为对象,基于ZigBee无线通信技术和嵌入式系统技术,设计了一套完整的电热膜供暖控制系统,该系统在保持电热膜供暖低碳环保优势的同时,将其完善成为了一个省电经济、操作简便、运行稳定、易于安装的产品,为电热膜供暖产品的市场推广进行了探索。本文首先给出了系统的整体设计方案,本文设计的电热膜供暖控制系统采用“集中管理,分散控制”的结构,可以将系统划分为无线温控器和嵌入式监控终端两个模块。无线温控器基于CC2530和Z-Stack软硬件平台开发,实现了温度的检测和控制、ZigBee无线通信以及人机接口功能。嵌入式监控终端基于S3C2440A和Qt/Embedded软硬件平台开发,实现了ZigBee/TCP网关、数据存储以及温控器监控管理人机界面等功能,其中ZigBee/TCP网关通过将ZigBee协议和TCP协议相互转换,从而使得用户可以通过手机远程查看和操作温控器。接下来,本文完成了无线温控器的软硬件设计,本文实现了按键式和触摸式两种款式的温控器,设计时充分考虑了外观、成本、用户体验等因素。硬件设计方面,以CC2530为核心设计了电源、温度检测与控制、人机接口等外围接口电路,并给出了具体实现的电路原理图；软件设计方面,基于Z-Stack协议栈开发了应用软件,实现了温度检测与控制、无线通信、人机接口等功能,并给出了关键子程序的流程图。然后,本文完成了嵌入式监控终端的软硬件设计,硬件设计方面,基于S3C2440A设计了电源、微处理器最小系统、网关模块、触摸屏等外围电路,给出了具体实现的电路原理图。软件设计分为底层软件设计和应用软件设计两部分,底层软件设计完成了嵌入式系统的内核移植、文件系统的制作、设备驱动程序开发等,应用软件基于Qt/Embedded库开发,实现了ZigBee/TCP网关、数据存储以及温控器监控管理等功能,并给出了关键子程序的流程图。最后,对本文设计的电热膜供暖控制系统进行了调试,测试结果表明,本文设计的无线温控器温度控制平稳、操作简单、无线通信稳定可靠,通过嵌入式监控终端可以方便的对多台温控器集中监控和管理,并且通过ZigBee/TCP网关可以实现远程手机监控。本文开发的电热膜供暖控制系统促进了电热膜供暖产品的市场推广,具有一定的实用价值。
[Abstract]:With the deterioration of haze situation in China, the transformation of extensive economic development mode is imminent. Low-carbon and environment-friendly electric heating film heating is one of the ideal schemes to replace the traditional centralized coal-fired heating system. It is also a feasible way to reduce the haze caused by heating. The electric heating film produces heat through the Brownian motion of the internal molecules under the action of an external electric field, with the exception of a small amount of loss. Most of the heat is transferred to the room by radiation and convection. In this paper, a complete electric heating film heating control system is designed based on ZigBee wireless communication technology and embedded system technology. While maintaining the advantages of low carbon and environmental protection in electric heating film heating, the system has become a power saving, economical, easy to operate, stable and easy to install product. The whole design scheme of the system is given in this paper. The electric heating film heating control system designed in this paper adopts the structure of "centralized management and decentralized control". The system can be divided into two modules: wireless thermostat and embedded monitor terminal. The wireless thermostat is based on CC2530 and Z-Stack software and hardware platform. The functions of wireless communication and man-machine interface for temperature detection and control are realized. The embedded monitoring terminal is developed based on S3C2440A and Qt/Embedded software and hardware platform. The functions of ZigBee/TCP gateway, data storage and man-machine interface monitoring and management of temperature controller are realized. The ZigBee/TCP gateway converts the ZigBee protocol and the TCP protocol to each other so that the user can view and operate the thermostat remotely through the mobile phone. Next, the hardware and software design of the wireless thermostat is completed. In this paper, two kinds of thermostats are realized, which are push-key and touch-type, and the factors such as appearance, cost and user experience are taken into account in the design. In the aspect of hardware design, the power supply, temperature detection and control are designed with CC2530 as the core. In the aspect of software design, the application software based on Z-Stack protocol stack is developed, which realizes the functions of temperature detection and control, wireless communication, man-machine interface, etc. And the flow chart of the key subroutine is given. Then, the hardware and software design of the embedded monitoring terminal is completed. Based on S3C2440A, the peripheral circuits, such as power supply, microprocessor minimum system, gateway module, touch screen and so on, are designed. The software design is divided into two parts: the bottom software design and the application software design. The bottom software design completes the kernel transplantation of the embedded system, the production of the file system, the development of the device driver, etc. The application software is developed based on Qt/Embedded library. The functions of ZigBee/TCP gateway, data storage and temperature monitor management are realized, and the flow chart of the key subprogram is given. Finally, the electric heating film heating control system designed in this paper is debugged. The test results show that the temperature control of the wireless thermostat designed in this paper is stable, the operation is simple, the wireless communication is stable and reliable, and the embedded monitoring terminal can conveniently monitor and manage the temperature of multiple thermostats. The electric heating film heating control system developed in this paper has promoted the market promotion of the electric heating film heating products and has certain practical value.
