Referring to fig. 1 or 2, the present embodiment provides a solar radiation detection system, whose basic structure includes a radiation detection device 100 and an action device 200; the irradiation detecting device 100 is a solar irradiation detector or solar irradiation detecting meter in the prior art, and has a detecting surface 110 for receiving irradiation. Since the radiation detection apparatus 100 is a mature prior art in this field, the detailed structure and operation principle thereof are not described in detail in this embodiment.
One of the improvements of the solar radiation detection system of this embodiment is that the radiation detection device 100 is connected to the action device 200, and the action of the action device 200 can drive the radiation detection device 100 to rotate in the horizontal direction and can make the included angle between the radiation detection device 100 and the vertical direction change between 0 ° and 90 °, specifically, the included angle between the detection surface 110 of the radiation detection device 100 and the vertical direction changes between 0 ° and 90 °, which can also be understood as that the radiation detection device 100 swings in a certain direction. Of course, it should be understood that the above-mentioned terms of orientation such as "vertical" and "horizontal" refer to the embodiment of the solar radiation detection system in the working state, and do not refer to the embodiment of the solar radiation detection system in each state.
It can be known from the above description of the structure that the solar irradiation detection system provided by this embodiment drives the irradiation detection device 100 to move through the movement device 200, so that the detection surface 110 of the irradiation detection device 100 is adapted to or parallel to the photovoltaic module to be detected, and no matter the photovoltaic module is horizontal or inclined, the detection precision is ensured, and the irradiation detection device 100 does not need to be set too much, so that the detection cost is saved.
The action device 200 of the present embodiment has a plurality of structural forms, one of which is that the swing fulcrum of the irradiation detection device 100 during swing and the rotation axis during horizontal rotation are not coincident, as shown in fig. 1, the action device 200 includes a first driving mechanism 210 and a second driving mechanism 220; the first driving mechanism 210 is connected to the second driving mechanism 220, and drives the second driving mechanism 220 to rotate in the horizontal direction; the second driving mechanism 220 is connected to the irradiation detecting device 100 and drives the irradiation detecting device 100 to change an included angle between 0 ° and 90 ° with respect to the vertical direction.

As can be seen from the attached drawings, the horizontal rotation axis of the irradiation detection apparatus 100 of the present embodiment is the output axis of the second motor, and the swing fulcrum of the irradiation detection apparatus 100 is the end position of the output axis of the first motor, which are not overlapped, and preferably, the distance between the two is also increased, for example, the length of the output axis of the first motor is extended, or the first motor and the second motor are connected through a horizontal plate (not shown in the figure), the swing fulcrum of the irradiation detection apparatus 100 is disposed at one end of the horizontal plate, and the rotation axis of the irradiation detection apparatus 100 rotating horizontally is disposed at the other end of the horizontal plate, so that the rotation range of the irradiation detection apparatus 100 can be increased, and the detection range of the irradiation detection apparatus 100 can be expanded.

The control device 300 of the present embodiment is electrically connected to the angle detection device and the action device 200, respectively, and controls the action device 200 to act based on the inclination angle obtained by the angle detection device, specifically, the angle detection device detects the inclination angle of the surface of the photovoltaic module to be measured and the horizontal direction or the vertical direction, after receiving and processing the inclination angle data, the control device 300 sends a corresponding control instruction to the action device 200, so that the detection surface 110 of the irradiation detection device 100 is parallel to the surface of the photovoltaic module to be measured or is in a detectable state, and then the irradiation detection device 100 performs the radiometric detection.
Therefore, the control device 300 of the present embodiment generally includes a comparator and a controller (not shown in the figure), the comparator is electrically connected to the angle detection device and the controller respectively, the angle detection device detects the angle data and transmits the angle data to the comparator, the comparator performs data comparison processing, and then sends the result to the controller, and the controller sends a control command to the action device 200 based on the result sent by the comparator, so as to complete the intelligent control process.
