Referring to FIG. 4 , the management device 100 obtains the synchronization information of the electronic device 10 through satellite positioning. Assuming that the erection engineer takes a picture of the electronic device 10 after the construction is completed, and uploads the photographed image to the database server 31 (server an aspect of the server 30) (step S410). The document engineer downloads the relevant images and data through the computer 40 (step S420 ), and the computer 40 classifies the images and data, and checks them to generate an inspection report (step S430 ). The application server 32 (another aspect of the server 30 ) forwards the audit report (step S440 ) for the auditor to confirm (through the computer 50 ), and provides the work rule serial number information accordingly (step S450 ). In this way, the construction confirmation process can be assisted by uploading the data to the cloud.

In another embodiment, the processor 150 may identify and/or analyze device defects based on the detection data. This equipment defect is related to construction negligence or equipment failure. For example, if the power connector is exposed and not protected by a waterproof cover, it may cause the connector to corrode. The bending range of the optical fiber transmission line is too large, which may cause the internal breakage of the transmission line, which may cause the signal to fail to transmit. The processor 150 can upload the image (ie, detection data) including the electronic equipment to the server 30 through the communication transceiver 130, and the corresponding database can check the equipment defects, and obtain the type of negligence or obstacle and its solution according to the equipment defects Information (ie, solutions to omissions or obstacles). The processor 150 can then present the solution information through the display 120 to assist the user in troubleshooting.

From this, it can be seen that the processor 150 can directly send the detection data (eg, the image captured by the electronic device 10 or the content input by the user) directly through the communication transceiver 130 . After analyzing the big data, the management device 100 can obtain the corresponding back-end information provided by the server 30 . Depending on the application context, the back-end information may be related to equipment settings, personnel operations (eg, construction processes, maintenance steps, etc.) or obstacle removal information.

In one embodiment, the present invention also provides stereoscopic viewing of the device. specific and In other words, the processor 150 can select the three-dimensional model according to the electronic device information. This solid model is a model of the electronic device 10 in a solid form. The processor 150 can then construct the three-dimensional model on the background image. The background image is, for example, a simulated virtual image or a real-time image currently captured by the image capturing device. Next, the processor 150 presents on the display 120 a picture in which the stereoscopic model and the background image are combined, so as to achieve augmented reality or virtual reality (VR), mixed reality (MR) and extended reality ( eXtended Reality, XR) or other real-world technologies that combine real/virtual systems. This three-dimensional model not only provides educational training, but also assists field personnel to understand the structure of the equipment.

5A-5D illustrate an example of an Augmented Reality (AR) application. Referring to FIG. 5A , it is assumed that the banknote I0 is used as the target and placed on a flat surface. Referring to FIG. 5B , the management APP enables the camera function, and the user can point the lens at the banknote I0 to determine the reference plane BI in the frame I2 displayed on the display 120, thereby (eg, through the stereo development tool and engine) to convert the electronic device The solid model EM of 10 is simultaneously presented in the picture I2. Referring to FIGS. 5C and 5D , a menu m4 may be provided on the user interface for the user to view the contents of the detailed rules, and the contents thereof may be different.

In order to provide the three-dimensional model, the management device 100 needs to perform construction work first. FIG. 6 is a flowchart of a three-dimensional model construction according to an embodiment of the present invention. Referring to FIG. 6 , the storage 140 stores basic models such as main bodies and parts in advance. The processor 150 evaluates and selects a prototype structure of the three-dimensional model (step S610 ), establishes the main body of the electronic device 10 from the prototype structure, and reserves space for parts in the main body (step S630 ). Then, the processor 150 may select the object (ie, the parts) and put it into the main body (step S650). In response to insufficient space for the object (eg, the part is too large), the processor 150 may reconstruct the main body, and repeat step S650. In addition, the processor 150 can classify the objects and the corresponding data into the storage 140 (step S670). Users can become familiar with it after repeatedly operating several objects. Finally, the assembled solid model can be converted into a specific file format and used by the management APP.

In addition, the present invention can also construct a three-dimensional model through real-time scanning. In one embodiment, the detection data is image scan data of the electronic device 10 . The processor 150 can construct a three-dimensional model based on the detected data. When the electronic device 10 is damaged, the processor 150 or the server 30 can analyze the damage and repair the three-dimensional model accordingly (through the three-dimensional model development tool). It is worth noting that each electronic device 10 may have several corresponding digital contents (eg, equipment parts, construction specifications, etc.), and these digital contents can be used for damage analysis and repair, and can be further used for education and training. .

For the three-dimensional model viewing, the present invention also provides an Ant-Man mode. In one embodiment, in response to a user's zoom-in operation (for example, the touch panel on the management device 100 receives an operation of moving two fingers away from each other), the processor 150 may display the three-dimensional model on the display 120 in a micro-scale . This microscopic scale represents that the diorama may exceed the size of the actual device.
