A hail disaster monitoring and prevention device and its protection method

Abstract

The invention discloses a hail disaster monitoring and prevention and control device and a protection method thereof. The hail disaster monitoring and prevention and control device includes a first column group and a second column group arranged on both sides of the agricultural cultivation ground. The hail protection device is installed on the column group and the second column group, and a hail monitoring system is installed on one side of the first column group. The hail monitoring system judges whether there is hail falling by monitoring the ambient temperature and the temperature in the hail monitoring system. A controller is connected, and the controller is electrically connected with the hail protection device to control the work of the hail protection device. The invention can quickly collect and detect hail when there is hail falling, and drive the hail protection device to respond quickly. Protect the crops before landing. At the same time, it can detect the end of the hail weather and automatically retract the protective net of the hail protection device, so as not to affect the normal growth and operation environment of the protected crops.

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
