In light of scientific management and continuous innovation in “intelligent weather projects”, we design an intelligent mobile office system in line with meteorological observatories through the WeChat public platform of “Qingdao Meteorology” (青岛气象 in Chinese) and its background API for secondary development. It aims to strengthen the management and accelerate the response of the meteorological service system, improving the operational efficiency of the meteorological observatory. The system is designed with a logic architecture consisting of layers of storage, technology, applications and users. It is built in a B/S structure and relies on the ASP.NET MVC framework. Besides, it depends on C# language in the background and HTML, Javascript, and CSS languages in the foreground. The main functions include “fault repair order”, “real-time work”, “electronic scheduling”, and “event registration”, initially enabling intelligent meteorological service and office management. Therefore, the system, with sound scalability, is convenient, fast, and practical, deserving popularization.
