Test device for mobile phone

Abstract

The invention provides a mobile phone testing device, comprising an interface, one ore more application interfaces, one or more power supply modules. The interface is used to connect the mobile phone with the mobile phone testing device and receive testing signals from the mobile phone. The application interfaces are used to send the mobile testing signals to a corresponding testing control device. The invention has the advantages of accomplishing the calibration testing before the mobile phone leaving the factory together with an integrated testing instrument and other equipments in the production phase; completing the fault location and software maintenance upgrade in the maintenance phase; reducing the device cost of research, production and maintenance in the whole life cycle of the mobile phone; simplifying the circuit design of the printed circuit board of the mobile phone; facilitating the debugging and testing in the research phase of the mobile phone; increasing the reliability of the system and decreasing the cost in the research phase.

Description

technical field [0001] The present invention relates to a mobile phone testing device, in particular to a mobile phone testing device for circuit board design, debugging and state tracking in the research and development stage of the mobile phone. In addition, the device can also be used for fault location and software maintenance and upgrading in the comprehensive test and maintenance stages of the mobile phone scale production process . Background technique [0002] At present, different tools are used in R&D, production and maintenance to communicate with mobile phones, and then to complete program development, calibration during mass production, fault location in the maintenance phase, and software maintenance and upgrades. To this end, it is necessary to develop various special tools, which not only increases the cost of development and assembly, but also makes it difficult to maintain and upgrade the entire system. [0003] In the prior art, in the research and develo...

Problems solved by technology

[0004] In view of the fact that the mobile phone test device in the research and development stage usually integrates various test ports and mobile phone components on the same printed circuit board, and the test port often needs to be plugged and pulled repeatedly during the test process, so the printed circuit board is extremely easy to damage. Moreover, since the printed circuit board supplies power to the test port and the mobile phone at the same time, it is impossible to perform power-saving tests on the mobile phone. In addition, in some cases, the test port and the mobile phone are integrated on the same printed circuit board, which may also affect the stability of the system. consistency, and the printed circuit board is not easily modified or supplemented
