Problems solved by technology

[0003] For the first type of memory card implementation, there is no need to plug and unplug, so we will not discuss it. For the second type, because it supports hot plugging, and all current systems cannot really do a good plug-in solution, it will often cause system crashes, Crash or cause damage to data files, the third implementation method, because the user must shut down the system, so the problems caused by the second situation will not occur, but the operation is time-consuming and inconvenient, so the user experience is not good

Embodiment Construction

[0040] Such as figure 1 As shown, the memory card hot swap control device of the present invention includes a locking mechanism 13 , a trigger circuit 14 and a detection and control circuit 15 . Wherein, the locking mechanism 13 is used to lock the memory card 11 placed in the memory card slot 10, so as to prevent the memory card from being pulled out when the read / write operation is in progress. The trigger circuit 14 is used to receive a card pullout instruction from the user requesting to pull out the memory card, and send a card pullout signal to the detection and control circuit 15 to convey the card pullout instruction. Once the detection and control circuit 15 receives the card pull signal from the trigger circuit 14, it detects whether there is data stream transmission between the memory card 11 and the host 20, and when there is data stream transmission, it determines that the memory card has read and write operations, and then controls the locking Mechanism 13 keeps...

Abstract

The invention relates to a storage card hot plug control method and device. The control method includes step 100 receiving a card pulling command requesting for pulling out a storage card; step 110 detecting whether reading-writing operation exists in the storage card; step 120 keeping the locking state of the storage card by a locking mechanism on yes judgment and step 130 removing the locking state of the storage card by the locking mechanism on no judgment. When a mobile terminal receives the card pulling command, a detection and control circuit is utilized to detect whether the reading-writing operation is conducted on the storage card. When the reading-writing operation exists, the circuit controls the locking mechanism to enable the storage card to be kept at the locking state, and locking of the storage card is removed when the reading-writing operation does not exist in the storage card. The method and device avoids severe results of crash, data loss, system collapse and the like caused by the fact that a user cannot judge whether the storage card is in the reading-writing state and directly pulls the storage card from a card slot, and simultaneously brings good experience to the user.

Description

technical field [0001] The invention relates to a removable memory card, and more specifically, to a method and device for controlling hot plugging of a memory card. Background technique [0002] Existing mobile terminals such as mobile phones generally have the following methods for memory card processing: one is to directly put the memory card inside the mobile phone, and the user is prohibited from plugging and unplugging; the other is a removable memory card that supports hot swapping by users , the user can unplug the phone while the phone is turned on. In others, the memory card can only be removed when the battery is removed. [0003] For the first type of memory card implementation, there is no need to plug and unplug, so we will not discuss it. For the second type, because it supports hot plugging, and all current systems cannot really do a good plug-in solution, it will often cause system crashes, Crash or cause damage to data files, the third implementation, bec...
