Description

Technical Field

[0001] The present invention relates to the field of meteorological disaster early warning technology, and in particular to a meteorological disaster early warning device based on smart agriculture. Background Art

[0002] As global climate change intensifies, extreme weather events are increasingly impacting agricultural production. Disasters such as droughts, heavy rains, and hailstorms not only cause direct losses to crops but also impact farmers' incomes. Smart agriculture has emerged as a response to this challenge. Leveraging technologies such as the Internet of Things, big data, and artificial intelligence, it enables intelligent and refined management of agricultural production. In particular, in the area of meteorological disaster early warning, high-precision weather monitoring and intelligent algorithm predictions can provide timely disaster warnings, helping farmers take effective countermeasures and mitigate the impact of meteorological disasters. Meteorological disaster early warning systems based on smart agriculture typically include a meteorological monitoring system, a data transmission and processing platform, intelligent algorithms and early warning models, and a disaster warning and decision support system. These systems work together to collect and analyze meteorological data in real time and provide early warning information to farmers via smart terminals, thereby optimizing agricultural production and improving agricultural resilience and efficiency. In the future, as technology advances, meteorological disaster early warning systems in smart agriculture will become even more accurate and intelligent, providing strong support for sustainable agricultural development.

[0003] After searching, the existing patent (publication number: CN116148952A) discloses a meteorological disaster warning device based on smart agriculture, whose structure includes a control box, a support rod, a detection mechanism, a solar panel, and a wind tester. The solar panel is embedded in the side of the support rod, the detection mechanism is installed on the side of the support rod, the wind tester is embedded in the upper end of the support rod, and the control box is installed on the side of the support rod. In the present invention, rainwater flows from the water storage mechanism to the weighing device for weighing, and the amount of rainwater is calculated based on the data of the change in rainwater weight, thereby obtaining the amount of rainwater in a certain period of time. When rainwater flows into the water storage tank, the timing switch connected to the closing mechanism starts the timing, and then under the control of the control box, the sliding mechanism in the limit mechanism drives the extrusion plate to move, and then the inclined plate drives the sliding block to slide and rise, and the weighing device is used to measure the real-time weight change of rainwater, changing the measurement method of flipping once per millimeter to avoid the problem of not measuring some rainwater and prevent part of the rainwater from not being measured when the rainwater is too heavy.

[0004] However, in the actual use of the above scheme, since meteorological disaster warning devices are crucial to ensuring farmland safety and improving agricultural production efficiency, these devices can monitor weather changes in real time, issue early warnings, and help farmers cope with disasters. However, since they often need to be set up outdoors and exposed to various extreme weather conditions, they are easily affected by extreme weather, and the stability and function of the equipment may be seriously affected. Specifically, poorly protected equipment is easily damaged by severe weather such as wind, rain, hail, extreme cold or high temperature, resulting in sensor failure, inaccurate data, or even direct cessation of work. Such equipment not only fails to provide timely warnings, but may also increase maintenance costs and shorten its service life.
