Description
Technical Field
The utility model belongs to the technical field of the amount of wind detection and specifically relates to a take hand-held type amount of wind measuring apparatu of angle correction.
Background
The existing hand-held air quantity measuring instrument needs the wind wheel to face the measured wind, so that the measured wind is perpendicular to the wind wheel, the wind wheel can accurately measure the passing air quantity, when the wind wheel is not perpendicular to the measured wind, the measured air quantity generates deviation due to the angle relation, therefore, a wind vane is arranged on the wind wheel, the error value of the wind wheel is corrected through the angle value measured by the vane, but the existing air quantity measuring instrument only has one wind vane, and the angle deviation of double degrees of freedom cannot be corrected well.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a take hand-held type amount of wind measuring apparatu's of angle correction hardware structure, this hardware structure is by software engineer programming back, and the deviation value that the angle brought when can well rectify amount of wind measuring apparatu's wind wheel is not facing being surveyed the wind.
Therefore, the utility model provides a take hand-held type amount of wind measuring apparatu of angle correction, include the organism and measure the wind wheel, the organism includes the controller, presses key group and display, has two wind vane on measuring the wind wheel, and each wind vane all includes pivot and wind vane, wind vane and pivot fixed connection, and two wind vane's pivot all is located and measures on the wind wheel place plane and two pivots are not parallel to each other, and two pivots all with measure the wind wheel and rotate and be connected, measure the wind wheel and have two angle sensor in order to measure the turned angle of two pivots respectively, measure wind wheel and the equal electricity of each angle sensor and connect the controller of organism.
Further, the machine body is electrically connected with the measuring wind wheel through a conducting wire, and the machine body is not fixedly connected with the measuring wind wheel.
Further, the display is an LCD display.
Further, the two rotating shafts are perpendicular to each other.
Further, the handheld holding rod is further included, the measuring wind wheel is fixedly connected with the holding rod, and the holding rod is located on the plane where the measuring wind wheel is located.
Further, the conducting wire passes through the holding rod and is connected with the measuring wind wheel.
Has the advantages that:
the two angle sensors transmit the measured angle values to the controller, the controller defines the angle of the vane facing the measuring direction of the wind wheel as the angle, the angles measured by the two angle sensors are respectively defined as X and Y, and the controller can well correct the deviation value brought by the angle of the wind wheel in the two freedom directions according to the values of the X and the Y.
