Technical Field

[0001] The utility model relates to the technical field of data acquisition, in particular to a data acquisition device based on computer servo control. Background Art

[0002] Data acquisition refers to the process of collecting data from various data sources, such as sensors, instruments, databases, etc. Its purpose is to obtain sufficient and accurate raw data for subsequent storage, analysis, processing, and visualization operations.

[0003] Solar radiation data is a common type of environmental data collection. It is crucial for many fields such as meteorology, solar energy utilization, and agriculture. It is an instrument specifically used to collect solar radiation data. It mainly uses sensors to sense various parameters of solar radiation, including total solar radiation, direct radiation, and scattered radiation.

[0004] In the process of realizing the present invention, the inventors discovered that the prior art had the following problems: 1. Some existing solar radiometers only have simple fixed-angle installation or single-dimensional adjustment functions, which makes it difficult to meet the precise requirements for collecting solar radiation data at different times, different geographical locations, and different application scenarios; 2. Since data is not collected continuously, and the existing solar radiometers lack protective design, the instruments are easily affected by environmental factors when exposed outdoors for a long time. Utility Model Content

[0005] The purpose of the present invention is to provide a data acquisition device based on computer servo control to solve the problems of fixed-angle installation or single-dimensional adjustment function, inability to adaptively adjust and lack of protection proposed in the above-mentioned background technology. The transmission gear of the present invention is a gear which is connected with the gear of the gear to the upper and lower ends of the gear train, and the gear is meshed with each other to form a round shank and a gear of the gear to move relative to each other.

[0006] Further preferably, both ends of the mounting base are provided with mounting holes, and one side of the mounting base is provided with a quadrilateral slot for placing electrical components, and a protective panel is rotatably connected to the surface of the slot.

[0007] Further preferably, a shaft rod passes through the axis center of the worm wheel, and the shaft heads at both ends of the shaft rod are rotatably connected to the inner wall of the mounting base plate, and the worm wheel forms a transmission structure through the worm.

[0008] Further preferably, the shaft at the axis center of the driven horizontal gear passes through the surface of the bogie and is fixedly connected to the bottom of the turntable, and the collector mounting seat forms a horizontal rotating structure through the turntable.

[0009] Further preferably, the visual cover is made of tempered glass and is semicircular, and one end of the visual cover is flipped 90° on the surface of the collector mounting seat through a hinge, and the other end of the visual cover is threadedly connected to the collector mounting seat via a quick-release bolt, and at the same time, the collector mounting seat is fixedly connected to the surface of the visual cover corresponding to the sensor element.

[0010] Further preferably, the bracket and one end of the slide groove and rack used for sliding connection to the embedded slide groove seat are all arc-shaped, and the embedded slide groove seat is rotatably connected to pulleys rolling on the slide groove on both sides, and the transmission gear is located on the opposite side of the pulley, and the transmission gears are coaxially connected, and the transmission gear is engaged with the rack and forms a transmission structure with it.

[0011] Further preferably, the accordion cover is folded in a Z shape and its bottom is glued to the surface of the mounting base plate, and the top of the accordion cover is movably connected to the bottom of the chassis between the transmission gear, and the accordion cover forms a folding structure through the transmission gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the vertical angle of the collector mounting seat is adjusted by a worm gear transmission structure. Combined with the feedback of the solar altitude angle sensor, it can accurately track the changes in the solar altitude. At the same time, the cooperation of the active and driven horizontal gears enables the collector mounting seat to rotate 360° horizontally, and accurately align with the solar azimuth according to the data of the solar azimuth angle sensor. This two-dimensional precise angle control effectively improves the accuracy of the solar total radiation sensor in receiving solar radiation. With the help of computer servo control, the device can automatically adjust the collector angle according to the real-time changes in the sun's position. This not only greatly reduces labor costs and human operation errors, but also can work continuously and stably under different weather and seasonal conditions, ensuring the continuity and integrity of data collection, and greatly improving the efficiency of data collection.

[0014] In this utility model, the quadrilateral groove of the installation base provides a special storage space for electrical components. The visual cover is made of tempered glass, which can protect the sensor from external impact and dust contamination during daily monitoring, and does not affect the sensor lighting due to its high light transmittance. In bad weather or when the equipment is idle, the accordion cover is unfolded by the transmission gear to form a protective barrier, which significantly extends the service life of the electrical components, sensors, etc. inside the device, and reduces the equipment failure rate and maintenance costs.

The solar altitude angle sensor (model L203) simultaneously monitors the solar altitude angle information and transmits it to the control host. The control host will control the corresponding servo motor to rotate the active horizontal gear 6 according to the received solar azimuth and altitude angle information, so that the driven horizontal gear 7 drives the turntable 8 to achieve 360° rotation in the horizontal direction, or use the servo motor to drive the worm gear 5 to rotate through the rotation of the worm 3. To achieve corresponding adjustment of the vertical angle of the collector mounting seat 9, thereby ensuring that the solar total radiation sensor (model LI-200R) on the collector mounting seat 9 can be accurately aligned with the sun to receive solar radiation.
