Abstract

A loading control method and system for a storage device are disclosed. The method comprises: judging whether a storage controller is valid through a first bus, and judging whether a storage controller is valid through a first bus, and acquiring a key of the storage controller if a positive judgement is made; judging whether the key is valid, commanding the storage controller to turn on a power supply of a storage device if a positive judgement is made; and loading the storage device through a second bus. According to the method, storage devices based on windows and android are allowed to be loaded after the storage device verification is successful, and by means of the method, data security of a user can be effectively protected, which provides reliable and effective protection for future private cloud service data.

Claims

1. A loading control method for a storage device, comprising:

judging whether a storage controller is valid through a first bus, and acquiring a key of the storage controller if a positive judgement is made;

judging whether the key is valid, commanding the storage controller to turn on a power supply of a storage device if a positive judgement is made; and

loading the storage device through a second bus;

wherein the step of judging whether a storage controller is valid through a first bus further comprises;

sending a broadcast command to the storage controller through the first bus;

acquiring identity identification information replied by the storage controller; and

judging whether the storage controller is valid according to the identity identification information.

2. The method according to claim 1, wherein the step of acquiring a key of the storage controller further comprises:

sending a command to the storage controller through the first bus; and

acquiring the key uploaded by the storage controller from the first bus.

3. The method according to claim 1, wherein the step of commanding the storage controller to turn on a power supply of a storage device further comprises:

sending a command to the storage controller through the first bus; and

waiting for the storage controller to turn on the power supply of the storage device.

4. The method according to claim 1, wherein the first bus is an RS485 bus, and the second bus is a USB bus.

5. A loading control method for a storage device, comprising:

uploading identity identification information of a slave device to a master device through a first bus according to a first command from the master device;

uploading a key of the slave device to the master device through the first bus according to a second command sent after the master device confirms the identity identification information; and

turning on a power supply of a storage device according to a third command sent after the master device confirms the key, so that the storage device is identified and loaded by the master device through a second bus.

6. The method according to claim 5, wherein the first bus is an RS485 bus, and the second bus is a USB bus.

7. A loading control system for a storage device, comprising:

a master device comprising a first port and a second port; and

a slave device comprising a third port, a fourth port, a power control system, a storage controller and a storage device;

wherein the first port is connected with the third port through the RS485 bus;

the second port is connected with the fourth port through the USB bus;

the storage controller is connected with the power control system through the third port; and

the storage device is connected with the fourth port;

the master device acquires identity identification information by the storage controller through the RS485 bus to judge whether the slave device is valid;

if the slave device is valid, the master device acquires the key from the storage controller through the RS485 bus and judges whether the key is valid; and

if the key is valid, the master device commands the storage controller through the RS485 bus to control the power control system to supply power for the storage device, so that the master device loads the storage device through the USB bus.
