DPIV collector attitude remote control adjustment system

Abstract

The invention relates to a DPIV collector attitude remote control adjustment system. The system comprises a DPIV collector, a hanging rod, an inner shell, an outer shell, a first motor, a second motor, an infrared remote control signal receiving processor and an infrared remote controller, wherein the first motor is fixed to a side wall of the inner shell, the DPIV collector is arranged in the inner shell and connected with a first rotating shaft of the first motor, the second motor is fixed to a side wall of the outer shell, the inner shell is arranged in the outer shell and connected with asecond rotating shaft of the second motor, the first rotating shaft and the second rotating shaft are horizontally arranged and are perpendicular to each other, the top of the shell is installed at afixed position through a hanging rod, the infrared remote control signal receiving processor is connected with the first motor and the second motor, and the infrared remote controller and the infraredremote control signal receiving processor are used for controlling the first motor and the second motor to rotate so as to adjust the attitude of the DPIV collector. The remote control device has advantages of being simple in structure, easy to operate and low in cost, and the attitude of the DPIV collector can be effectively and remotely controlled.

Description

technical field [0001] The invention belongs to the field of test instruments, and mainly relates to a novel electromechanical structure, that is, a DPIV collector posture remote control adjustment system, so as to realize remote control of the DPIV flow field collector posture. [0002] technical background [0003] Digital Particle Image Velocimetry (DPIV for short) is a flow field measurement technology, which is widely used in the research of aerodynamics and hydrodynamics. In the study of water conservancy model tests, DPIV systems can be roughly divided into two types. According to the different shooting ranges of DPIV collectors, they can be divided into full flow field DPIV systems and partial flow field DPIV systems. [0004] The local flow field DPIV system focuses on the measurement of the local flow field, which has the advantages of high precision. However, due to the limitations of the site and instruments, the range that the collector can capture is small, and ...

Problems solved by technology

Due to the lens, image distortion will appear at the edge of the captured image, which will affect the accuracy of data collection at the edge of the image

When carrying out model tests at night, the reflection of the light has a great impact on the data collection of the collector, and the fixed collector cannot realize attitude adjustment to meet the shooting requirements (existing full-flow field DPIV systems such as figure 1 shown)
