Description

Device for implementing hot swap function

The present invention is to replace a hard disk driver (hereinafter referred to as HDD) of a computer by using the hot swap function, and in particular, the HDD built into the computer main body may be used as a floppy disk driver (FDD or below) of a computer. HDD cabinet is installed in the space where the HDD can be inserted and taken out so that the user can freely detach the HDD from the outside.

Here, the hot swap refers to a function that can be replaced with a new HDD without affecting the operation of the system when an error occurs in the used HDD.

As is well known, a conventional computer device includes an HDD and a power supply terminal for applying power to the HDD, and a data transmission line for transmitting and receiving data.

In such a conventional device, a user using a computer may turn off the power of all systems in order to replace the HDD for data backup, and then open the cover covering the computer main body to disassemble the HDD from other accessories to replace the HDD. In the meantime, after replacing the HDD, the cover must be re-set to operate the computer.

However, in order to mount a new HDD, the conventional device is to open the cover of the computer body to disassemble the power terminal and signal terminal connected to the HDD, and connect the new HDD to the power terminal and signal terminal in the reverse order of disassembly. After that, cover the main body of the computer, turn on the system, and reset the HDD to use the computer.

An object of the present invention is to solve the above-mentioned conventional problems, and in particular, by using a hot swap function, using a simple stabilization circuit and a program without a separate controller, an integrated development environment of a general computer is hard. The present invention provides a device for implementing a hot swap function, which makes it easy to replace a HDD by implementing a hot swap function even with a disk.

In order to achieve the above object, an apparatus for implementing the hot swap function of the present invention includes: an HDD cabinet capable of inserting and taking an HDD into an FDD storage space portion of a computer main body; A stabilization circuit stage mounted to the front of the HDD cabinet and for stabilizing power input to the HDD from a switching mode power supply (hereinafter referred to as SMPS); Technical features of the present invention include a second switch mounted on the right or left side of the stabilization circuit stage to control the operation of the circuit.

The apparatus for implementing the hot swap function of the present invention has a more convenient effect in terms of the user's environment by replacing a new HDD through a stabilization circuit and a program using a hot swap function without turning off the computer system. .

Hereinafter, with reference to the accompanying drawings, the configuration and operation of an embodiment according to the technical idea of the device for implementing the hot swap function of the present invention in detail as follows.

EXAMPLE

First, as shown in FIG. 1, a stabilization circuit stage 30 mounted on the HDD cabinet 10 and stably supplying power applied to the HDD 20; A second switch 40 protrudingly mounted to the front portion of the stabilization circuit stage 30 to control power of the circuit; An HDD cabinet 10 capable of inserting and taking an HDD into a space capable of storing an FDD; This embodiment is constituted by the HDD 40.

As shown in FIG. 2, the stabilization circuit stage 30 includes a first power connection portion 31 connected to a signal output terminal of the SMPS; A second power connection unit 32 connected to the signal input terminal of the HDD; A first switch part 33 for applying the power applied from the first power connection part 31 to the second connection part 32; A delay unit 34 which prevents sudden power supply to the HDD when the second power connection unit 32 and the HDD are connected to each other; This embodiment includes a second switch 40 for applying current to the base terminal of the first switch unit 33.

On the other hand, the first power connecting portion 31 and the second power connecting portion 32 is composed of two ground terminals, + 5V, + 12V terminal.

Therefore, the present embodiment configured as described above will be described in detail.

1 and 2, when the user needs to replace the backup HDD of the computer while the computer is in use, when the HDD is removed, the second switch 40 is turned off and current flowing through the TR base terminal of the first switch unit 33 is also cut off.

When a new HDD is inserted into the HDD cabinet 10 after a predetermined time, a second switch which is mounted on the HDD cabinet 10 and protrudes from the surface of the second power connection unit 32 connected to the signal input terminal of the HDD 20 ( Pushing 40) shorts the switch.

On the other hand, when the second switch 40 is short-circuited, the current is applied to the base terminal of the first switch unit 33, so that TR is conducted. Accordingly, the first power connection unit 31 is moved from the first power connection unit 31 to the second power connection unit 32. Power is applied.

However, when the power is suddenly applied, the parts of the HDD 20 may be destroyed. In this case, delays may be caused by the appropriate delay time of the first switch unit 33 and the charging time of the delay unit 34. It is possible to prevent component damage of the HDD 20 due to sudden power supply.

As described above, the device for implementing the hot swap function of the present invention is operated to be replaced with another HDD through a stabilization circuit and a program, in particular, without turning off the computer system. It is a convenient effect.
