Abstract With the development of Internet of things technology, the real-time collection and transmission of meteorological data has become particularly important. Especially in response to emergencies such as natural disasters, it is very important to improve the efficiency of decision-making by quickly obtaining accurate meteorological observation data. However, the traditional method of meteorological data collection and transmission has a large delay in data acquisition due to the conversion of public network and internal network, which affects the timeliness of emergency decision-making. This paper proposes a solution based on the Internet of things platform combined with MQTT protocol, which aims to realize the efficient and reliable real-time collection and transmission of meteorological data, shorten the data acquisition time, improve the emergency response speed, and meet the needs of temporary observation.

With the intensification of the impact of global climate change in recent years, exireme weather events have occurred frequently, causing a huge threat to human society. In order to effectively respond to such disasters, the meteorological department often carries out temporary observation for the disaster site, and timely and accurate meteorological observation data is particularly important[1]. The traditional methods of meteorological data collection and transmission are difficult to meet the needs of modern gency This paper proposes an efficient real-time meteorological data collection and emergency response system based on the Internet of things platform. Through the introduction of advanced Internet of things technology and MQTT protocol[3-3], it realizes the rapid transmission and processing of meteorological data.
Traditional methods of meteorological data collection and transmission usually rely on regular or irregular data exchange between observation equipment at fixed stations and central data processing system. There are many ways to realize these transmission methods, but there are some limitations, especially in the realtime and reliability of transmission[6]. The following are some of the main features of traditional meteorological data collection and transmission methods.
Manual observation; in the early days, the collection of meteorological data mainly depended on manual observation. This method is not only inefficient, but also prone to error. It is because all data needs to be collected and recorded by people, and is vulnerable to personal subjective factors and...
