Logistical Remote Association Repair Framework Using Smartphones Based on the Android Platform

A Logistical Remote Association Repair Framework (LRARF) is developed to aid repairmen for keeping the large-scale system available in this paper. The framework constituted by smart mobile phones of repairmen, Database Management System (DBMS), a maintenance support center (MSC) and wireless networks. When the modules cannot be recognized, the repairman uses smart mobile phones to capture QR-codes and the image of fault circuit boards. Moreover, we use Android to develop the image recognizing algorithm on the smart mobile phones of repairmen. The captured QR-codes or images of the invalid modules can be recognized via our algorithm such that the features can be transmitted to the DBMS. In addition, DBMS also transmits the maintenance manual back to the maintenance staff. If the invalid modules still cannot be recognized, the repairmen and center engineers can connect through live video to obtain the relevant information. The experimental results validate the practicality of LRARF and Android platforms applied to recognition of invalid modules. Furthermore, the live video can be also recorded on the MSC synchronously.
