Wind power-and-direction testing device and wind power-and-direction testing method

Abstract

The invention relates to the technical field of a terminal, and discloses a wind power-and-direction testing method and a wind power-and-direction testing device. According to the invention, the wind power-and-direction testing device comprises a fixed bracket, a wind plate, a slide rheostat and a connector; one end of the wind plate is hinged with the fixed bracket, and the other end is suspended; the slide rheostat is arranged on the fixed bracket; the connector is connected with a mobile terminal; one end of the slide rheostat is connected with a power supplying pin of the connector, and the other end is connected with a grounding pin of the connector; the sliding end of the slide rheostat is mechanically connected with the wind plate and is electrically connected with a signal acquiring pin of the connector; wherein, in rotation of the wind plate, the moving end is driven to move; the voltage of the slide rheostat is output through a signal acquiring pin; and the mobile terminal is used for calculating the wind power according to the voltage. An embodiment of the invention further provides a wind power-and-direction testing method. Compared with the prior art, the wind power-and-direction testing method and the wind power-and-direction testing device can improve wind power-and-direction testing accuracy and furthermore have advantages of miniature structure and high convenience in carrying.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a method and device for testing wind force and direction. Background technique [0002] Wind speed and wind direction are very important parameters to reflect meteorological conditions, and have an important impact on environmental monitoring, air conditioning, and industrial and agricultural production. Therefore, it is of great practical significance to measure wind speed and wind direction quickly, timely and accurately. Traditional wind cups and wind vanes are still widely used detection devices, but these devices are large in structure and inconvenient to carry; Patent No.: 201510346251.X discloses a mobile phone pendant and mobile APP that can test wind force and direction. A capacitive pen that can swing with the wind is suspended on a fixed bracket, and the wind force and wind direction are tested by a certain swing direction and angle when subjected to wind force.

Traditional wind cups and wind vanes are still widely used detection devices, but these devices are large in structure and inconvenient to carry; Patent No.: 201510346251.X discloses a mobile phone pendant and mobile APP that can test wind force and direction. A capacitive pen that can swing with the wind is suspended on a fixed bracket, and the wind force and wind direction are tested by a certain swing direction and angle when subjected to wind force. The wind force and direction are recorded by the sensing position of the mobile phone screen, and then the mobile phone application software interprets and displays the wind force. A device for wind direction value, but the resistance value of the sliding rheostat is measured by the coordinates of the touch screen. Due to the large error of the touch screen coordinates, the detected wind force and direction value is not accurate enough
