Problems solved by technology
[0006] The purpose of the present invention is to provide a detection method for hot-swapping faults of memory cards, which can solve the problem that the detection method for hot-swapping faults of memory cards in the related art is likely to cause fatigue damage to the card slot, and requires a large number of detection personnel. Due to the high detection cost , so it is difficult to carry out large-scale detection, which leads to the problem of low reproduction efficiency and poor detection accuracy of memory card hot-swapping faults

Embodiment Construction
[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0028] figure 1 Shows a flow chart of the detection method according to the first embodiment of the present invention, the method includes the following steps:
[0029] Step S101, connecting or cutting off the power supply of the memory card every predetermined time to simulate hot swapping;
[0030] Step S102, judging whether a hot-swap failure occurs for each simulated hot-swap;
[0031] In step S103, the detection result of the hot plug fault is obtained according to the judgment result.
[0032] In this embodiment, at first, the power supply of the memory card is connected or cut off at predetermined intervals to simulate hot plugging, and for each simulated hot plugging, it is judged whether a hot plugging fault occurs, and then the detection result of the hot plugging fault is obtained according to the judgment result, Where...

The invention provides a method for detecting hot plug fault of a storage card, which comprises the following steps: connecting or cutting off a power supply of the storage card to simulate hot plug at preset time interval; judging whether the hot plug fault happens in each hot plug simulation; and obtaining the detection result of the hot plug fault according to the judgment result. The invention also provides a device for detecting the hot plug fault of the storage card, which comprises a simulation module, a judgment module and a detection module. The method and the device solve the problems that the method for detecting the hot plug fault of the storage card in the prior art has low reproduction efficiency for the hot plug fault of the storage card and has poor detection precision so as to reduce the detection cost, and are favorable for carrying out mass detection so as to improve the reproduction efficiency and the detection precision of the hot plug fault of the storage card.
Description
technical field [0001] The invention relates to the field of digital memory cards, in particular to a method and device for detecting hot-swapping faults of memory cards. Background technique [0002] Digital devices such as mobile phones and digital cameras are becoming more and more popular in people's lives. In order to meet the needs of expanding or moving storage space, digital devices increasingly use external memory cards, including SD cards (Secure Digital Memory Card, Secure Digital card), T card, MMC card (Multi Media Card, multimedia card), etc. [0003] Many digital devices have a memory card hot-swapping function. If the memory card hot-swap fails, it will seriously affect the normal use of the user. Statistics show that among all mobile phone failures complained by users, the corresponding failures of the memory card increase the fastest, including no response when the memory card is inserted and removed, abnormal initialization when the memory card is inserte...
