A kind of intelligent umbrella and automatic rain-blocking method

Abstract

The invention provides an intelligent umbrella and an automatic rain protection method, which detects the wind direction and the wind speed v of the current wind direction w , to detect the pressure P of raindrops on the umbrella surface, the controller set inside the umbrella handle determines the pressure detection value P detected by the second detection device in the wind direction, according to v w , P and the corresponding relationship between the pressure and the falling speed of raindrops, and determine the falling speed of raindrops v r , and according to v w and v r Determine the first angle θ, and control the movement of the umbrella surface so that the angle between the umbrella surface and the umbrella handle is θ; the present invention can automatically adjust the state of the umbrella surface according to the current wind direction, wind speed, and rainfall, so that the umbrella surface can be aligned The falling direction of raindrops has a better effect of blocking rain. Moreover, the umbrella can be controlled in a timely and accurate manner without the need for the umbrella holder to adjust the state of the umbrella. Solve the problem that the umbrella holder cannot adjust the umbrella in time and get wet by the rain.

Description

technical field [0001] The invention relates to the technical field of umbrella equipment, in particular to an intelligent umbrella and an automatic rain-shielding method. Background technique [0002] Umbrellas are all necessary tools for people on rainy days. However, the direction of the rain is not fixed, and it is sometimes difficult for people to detect that the rain has fallen on the clothes. [0003] When using an umbrella, due to the limitation of the rain-shielding area of ​​the umbrella, the umbrella holder often needs to adjust the direction and position of the umbrella in the hand according to the rainy situation, so as to avoid being drenched by the rain. The falling direction of the raindrops follows the wind speed and direction. In rainy and windy weather, the wind will change the direction of the rain, making the rain that originally fell vertically fall at an angle. In this way, even if you are holding an umbrella, the umbrella cannot The rain coming from...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an intelligent umbrella and an automatic rain-shielding method, which are used to at least partially solve the problems that the existing umbrellas cannot automatically adjust the direction of the umbrella surface, and the rain-shielding effect and flexibility are poor
