| 中文摘要 | 一米红外太阳望远镜是目前国内外唯一的地平式真空太阳望远镜，它主要用于太阳活动区磁场的精细光谱分析和时空精细结构分析。众所周知，使用望远镜进行日常观测时要时刻注意天气的变化，因为天气的好坏将会直接影响望远镜的成像质量。为了实现对天气变化的实时监测，我们需要设计一个气象站来采集气象数据并将它们传输到控制计算机上，以便于维护人员对天气的变化做出及时的响应。 本文提出了一种基于嵌入式Internet技术的网络气象站的设计方案，使用基于ARM7内核的LPC2103和独立的网络控制器ENC28J60构建了网络气象站的硬件平台；通过深入详细地研究TCP/IP体系结构，并结合本系统的具体工作环境，设计了一个精简但功能完善的TCP/IP协议栈，然后将此协议栈移植到硬件平台上来实现嵌入式系统的网络通信。最后，针对硬件平台设计了一个基于Winsock控件的上位机网络通信软件实现数据的远程传输。实验证明，该设计方案完全可行，基本达到了预期的效果。 |
| 英文摘要 | The one-meter infrared solar telescope is the only horizon vacuum solar telescope at home and abroad, the science case is fine spectrum analysis and spatial-temporal fine structure study of the solar activity region magnetic field. As is well known, we should always pay attention to the change of the weather in our daily observation, because the weather will affect the image of the telescope directly. For this reason, we need to design a weather station for monitoring the change of the weather; meanwhile, the telescope’s maintenance staffs can also response to the weather change as soon as possible. In this thesis, a design method of network weather station which based on embedded internet technology was introduced. The hardware is designed by LPC2103 which is based on ARM7-core and a single network controller ENC28J60. The characteristic and key technology of the TCP/IP architecture was deeply researched and analyzed. Then a light TCP/IP stack was designed, compared with the traditional TCP/IP protocol, this stack is simpler but the function is perfect. After that, the stack was migrated into the hardware platform in order to implement network communication. Finally, host computer software based on Winsock was designed in order to achieve remote data. The test result showed the feasibility of the research. |
