Logistical Remote Association Repair Framework
The Remote Association Repair Framework Process
The Logistical Remote Association Repair Framework process is shown in Figure 2. In this process, we design four operation stages to identify a module:
Stage 1 is the invalid module identification by repairmen. Stage 2 is the QR-code recognition of invalid modules. Stage 3 is the image recognition of invalid modules. Stage 4 is to assist identification by the MSC engineers.
In Stage 1, repairmen identify the failed module. If the modules can be identified, then the modules will be repaired. If the modules cannot be recognized, then the repairman may capture the module QR-codes (Stage 2). If the QR-codes are damaged, the repairman uses a smart mobile phone to capture an image of the module (Stage 3). The captured QR-codes and images are transmitted to the DBMS so the invalid modules can be recognized via our algorithm. Furthermore, the image features will be extracted by our APP and transferred to a cloud database to search for the best matching module. Moreover, DBMS will automatically search for the maintenance manual corresponding to the invalid module and transmit back to the maintenance staff. If modules are not recognizable, the repairmen and center engineers can obtain the relevant information about the invalid modules through live video. Table 1 shows the four-stage operations and situational modes
