In step S804, the junction box receives the identification trigger signal and then receives the identification command, and if one of the junction boxes receives both the identification trigger signal and the identification command, the junction box uploads the identification code corresponding to the junction box to the identification code identification module. After the identification code is uploaded to the junction box, the identification trigger signal is sent to the signal receiving line of the next solar assembly receiving box through the identification trigger signal output line of the junction box, and the fact that the identification code can be uploaded to the next junction box is guaranteed.
In step S805, the identification code recognition module receives the identification code, and establishes a one-to-one mapping relationship between the identification code and the code number and the actual physical position of the solar module. Further, after the identification code recognition module receives the identification code, the identification code recognition module modifies the code number, and broadcasts a new recognition command to each junction box again in a communication mode (such as power line carrier communication, wired communication or wireless communication, etc.), wherein the new recognition command carries the modified code number, so that the next solar module receiving box can receive a recognition trigger signal and a recognition command until receiving a recognition trigger signal returned by the junction boxes in the series circuit or until determining that the number of the solar modules completing identification of the identification code reaches a preset number threshold. Or, in the connection mode as shown in fig. 1, until the number of the finished uploading identification codes reaches the preset number threshold.
Through the operation steps, the mapping relation among the identification codes, the code numbers and the physical positions of all the solar assemblies is stored through the storage module, the mapping relation among the identification codes, the code numbers and the physical positions can be further acquired by the identification code identification module or the upper computer, and then in the subsequent steps, the identification code identification module or the upper computer only needs to send data reading commands to the identification codes in sequence, so that the information of the corresponding solar assemblies can be read in sequence. Moreover, because the identification code is associated with the code number and the physical position, the identification code identification module or the upper computer also acquires the real-time information of the solar assembly at the physical position, when a certain solar assembly is invalid or abnormal, the abnormal assembly can be conveniently and quickly found and replaced through the identification code corresponding to the abnormal information, the code number and the actual physical position, and the manual maintenance and repair cost is greatly reduced.
As another embodiment of the present invention, as shown in fig. 9, the steps S803 to S805 may specifically include:
step S901, the identification code identification module sends an identification trigger signal to a junction box (the first junction box in a loop) directly connected in series with the identification code identification module through an identification output line;
step S902, the junction box directly connected in series with the identification output line of the identification code identification module receives an identification trigger signal through a signal receiving line;
step S903, the identification code identification module broadcasts identification commands to each junction box in a communication mode such as power line carrier communication, wired communication or wireless communication;
step S904, the junction box directly connected in series with the identification output line of the identification code identification module receives the identification trigger signal and the identification command, and uploads the identification code corresponding to the junction box to the identification code identification module;
step S905, the identification code recognition module receives the identification code uploaded by the junction box and associates the identification code with the code number and the physical position of the solar assembly;
step S906, after the identification code is uploaded by the junction box, an identification trigger signal is sent to a signal receiving wire of the next solar assembly receiving box through a signal sending wire;
step 907, after the identification code recognition module receives the identification code, returning to step 903 until the identification code recognition module receives the recognition trigger signal sent by the junction box directly connected in series with the identification code recognition module, or until the number of the uploaded identification codes reaches a preset number threshold.
It should be noted that steps S905 and S906 may be executed, or step S906 may be executed first and then step S905 is executed, which is not limited in this embodiment of the present invention. Under the condition of ensuring that the invention can be realized, the sequence of the steps can be adjusted according to the requirement, and the adjusted technical scheme is within the protection scope of the invention.
Therefore, in the embodiment of the invention, the plurality of solar assemblies are connected in series through the identification lines, the identification triggering signals and the identification commands are combined, the junction box is triggered to upload the identification codes, the identification codes of the solar assemblies are sequentially acquired, and therefore, the identification codes, the code numbers and the physical positions of the solar assemblies are automatically acquired and automatically associated. Therefore, the embodiment of the invention can solve the problem of high error rate caused by non-automatic acquisition of identification information and physical position information, and can also realize automatic identification and physical position positioning of the module modules in application systems such as BIPV (solar power generation tile, solar power generation wall surface) and solar pavement module or other solar modules.
