摘要
对提取互联网免费实时发布的城市气象信息并在LED屏输出显示问题进行了研究,提出了在.NET开发平台基于Microsoft mshtml DOM接口通过递归提取气象信息的算法设计,并进一步给出了通过取模及挂载第三方EXE的方式实现LED显示的相关技术。基于所提出的算法及相关技术所设计的系统通过了运行测试,验证了算法及系统设计的可行性。
The extraction of free and real-time released city meteorological information on the internet and its display on the LED screen were studied, after the analysis of Web page HTML tree tag structure of the meteorological information, the algorithm through the recursion to extract the meteorological information based on the Microsoft mshtml DOM interface in the. NET development platform was put forward. Furthermore, the related technology of LED display by modulus and mount third EXE was presented. The system based on the proposed algorithm and related technology was tested in real operation, which verifies the feasibility of the algorithm and the system design.
