Hail disaster monitoring, preventing and controlling device and protection method thereof

Abstract

The invention discloses a hail disaster monitoring, preventing and controlling device and a protection method thereof. The hail disaster monitoring, preventing and controlling device comprises a firststand column set and a second stand column set which are arranged on the two sides of agricultural cultivation ground, wherein hail protection devices are arranged on the first stand column set and the second stand column set; a hail monitoring system is arranged on one side of the first stand column set and judges whether hail falls or not by monitoring an environment temperature and the inner temperature of the hail monitoring system; the hail monitoring system is connected with a controller; and the controller is electrically connected with the hail protection devices and used for controlling the hail protection devices to work. According to the invention, hail can be rapidly collected and detected when the hail falls, and the hail protection devices are driven to rapidly respond, so crops and the like are protected before a large amount of hail falls; and the end of hail weather can be detected, and protection nets of the hail protection devices can be automatically folded, so thenormal growth and operation environment of the protected crops is not influenced.

Description

technical field [0001] The invention belongs to the technical field of hail detection and hail disaster protection, and in particular relates to a hail disaster monitoring, prevention and control device and a protection method thereof. Background technique [0002] Hail is one of the main disastrous weathers in my country, which causes great losses to agriculture every year. Hail is formed by strong humid and hot air rising and condensing into ice and then forming hail. This kind of strong air convection usually occurs in summer and autumn. At present, lightning positioning systems, satellite cloud images, and weather radars are often used to detect and identify hail clouds, and then predict hail weather in advance. However, the positioning accuracy and prediction efficiency of these technologies are not ideal. [0003] In order to solve the above technical problems, a greenhouse hail protection device has appeared on the market. This type of protection device can be used to ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned type of greenhouse hail protection device has a simple overall structure. The temperature sensor detects in real time whether there is hail in the hail collection bucket, and protects the greenhouse film through the lifting and falling of the quilt to prevent damage to the greenhouse due to hail disasters; but this type of greenhouse hail The protection device cannot effectively distinguish between hail and snowfall, cold wave, freezing rain and other low-temperature weather, that is, the temperature sensor will trigger the output of an effective signal when the temperature is lower than the set temperature. The control accuracy is low and it is susceptible to environmental interference; Quilt devices have a certain response time, and hail weather can cause large-scale damage in a short period of time. This type of existing technology cannot quickly identify the landing of hail, and then quickly make a protective response, thereby reducing the use effect. Field crops, quilt control cabinets, rolling quilt devices, equipment installation infrastructure and other facilities have a large implementation space and construction capital investment, which is not suitable for large-scale popularization in the open air
