Description

Computer device

The present invention relates to a computer device, and more particularly to a temperature control method for a light emitting diode module by adjusting a color temperature.

With the popularity of electronic products, computer devices have become an indispensable tool in people's lives. However, in today's technology, in order to provide better functionality and human interface, the computer device chooses to provide more convenient buttons on the user interface (such as a keyboard) that is easily accessible to the user (for example, directly opening the application or Start peripheral devices on the computer device, so that users can use it more easily.

Taking an optical storage medium (disc) as an example, the start switch of the computer device of the present invention is no longer disposed on the optical disk drive, but is instead configured on an operation interface (for example, a keyboard) that is more easily accessible to the user. In this way, when the user triggers the start switch of the CD player, the enable signal generated by the trigger action corresponding to the user on the start switch is used to turn on the switch between the CD player and its required operating voltage. The operating voltage can be obtained by the optical disk drive. Then, the computer device transmits the command through the configured Serial Advance Technology Attachment (SATA) interface to start the CD player and exit the carrier of the CD player. This conventional practice requires a complicated software program to generate the command to start the CD player and increase the burden on the system.

The present invention provides a computer device that simplifies the software program required to initiate control of an optical access medium.

The invention provides a computer device comprising an optical access medium, a start switch, a power switch and a controller. The optical access medium has a carrier disk. The start switch is coupled to the optical access medium and generates an enable signal when the start switch is triggered. The power switch is coupled between the operating voltage and the optical access medium. The controller is coupled to the optical access medium, the activation switch and the power switch for receiving and turning on the power switch according to the enabling signal to provide an operating voltage to the optical access medium. The controller delays the enable signal to generate a virtual enable signal and directly provides the virtual enable signal to the optical access medium to cause the optical access medium to be activated and exit the carrier.

In an embodiment of the invention, the enable switch is coupled to the pull-up resistor and generates an enable signal for the negative pulse when the enable switch is triggered.

In an embodiment of the invention, the start switch is coupled to the pull-down resistor and generates an enable signal for the positive pulse when the start switch is triggered.

In an embodiment of the invention, after the controller receives the enable signal, the timing action is initiated. And when the timing result of the timing action is equal to the critical timing value, a virtual enable signal is generated.

In an embodiment of the invention, a platform control hub is further included. The platform control hub is coupled between the controller and the optical access medium, and the controller transmits a reset command by the platform control hub to cause the optical access medium to perform a reset action.

In an embodiment of the invention, the controller further detects whether an optical storage component has been placed in the optical access medium to turn the power switch on or off.

In an embodiment of the invention, the controller is a General Purpose Input Output (GPIO) controller.

In an embodiment of the invention, the activation switch is disposed at a position outside the optical access medium in the computer device.

Based on the above, after the controller receives the enable signal generated by the trigger start switch, the present invention turns on the start switch to provide the operating voltage and the optical access medium, and delays the enable signal to generate a virtual enable signal. The controller directly provides a virtual enable signal to the optical access medium to initiate and exit its carrier.

The above described features and advantages of the present invention will be more apparent from the following description.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a computer device 100 according to an embodiment of the present invention. The computer device 100 includes a power switch 110, a controller 120, a platform control hub 130, an optical access medium 140, and a start switch 150. The optical access medium 140 (eg, a CD player) has a carrier (not shown), and the activation switch 150 is coupled to the optical access medium 140. Moreover, when the start switch 150 is triggered by the user, the enable signal EN is generated correspondingly. In this embodiment, when the enable switch 150 is not triggered, a high level signal that is pulled up by the power supply voltage VDD2 through the pull-up resistor R1 is provided. When the start switch 150 is triggered, a negative pulse enable signal EN is provided.

The controller 120 is coupled to the power switch 110, the start switch 150, and the platform control hub 130. The controller 120 receives the above-described enable signal EN when the start switch 150 is triggered. After receiving the enable signal EN, the controller 120 first turns on the power switch 110 according to the enable signal EN, so that the operating voltage VDD1 can be smoothly supplied to the optical access medium 140. Moreover, the controller 120 transmits the reset signal RST to the optical access medium 140 through the platform control hub 130 to cause the optical access medium 140 to perform a reset operation. After the optical access medium 140 obtains the stable operating voltage VDD1 and completes the resetting operation, the controller 120 generates the virtual enable signal DEN and directly provides the virtual enable signal DEN to the optical access medium 140 to enable the optical access medium 140. Start and exit its carrier tray for the user to place the optical storage element (disc).

It is particularly noted here that the virtual enable signal DEN is obtained by the controller 120 delaying the enable signal EN. That is to say, when the controller 120 receives the enable signal EN, it will start a timing action correspondingly, and when the timing result of the timing action is equal to the critical timing value, the virtual enable signal DEN is correspondingly generated. In addition, after the virtual enable signal DEN is successfully generated, the controller 120 can reset this timing action. Of course, this timing action can be performed by using the clock inside the controller 120 through the software, or by using a simple timer hardware. The critical timing value can be set by the designer according to the actual needs. The setting of this critical timing value is focused on balancing the stability of the optical access medium 140 with the startup speed (longer critical timing values provide higher stability of the optical access medium 140, shorter critical timing values) A faster start speed of the optical access medium 140 can be provided.

It should be noted that in the computer device 100 of the embodiment of the present invention, the controller 120 further detects whether an optical storage component (disc) is placed in the optical access medium 140. If the optical access medium 140 is detected to have the optical storage component placed, the power switch 110 will not be disconnected and the operating power supply VDD1 to the optical access medium 140 will continue to be provided. In contrast, if the optical access medium 140 is detected that no optical storage component is placed, the power switch 110 is turned off to save power consumption.

Incidentally, the start switch 150 in the computer device 100 of the embodiment of the present invention is disposed at a position outside the optical access medium 140 in the computer device 100. That is to say, the start switch 150 is not disposed on the optical access medium 140. In addition, the controller 120 in the computer device 100 is a General Purpose Input Output (GPIO) controller.

Please refer to FIG. 1 and FIG. 2 together. FIG. 2 is a flow chart showing the operation of the computer device 100 according to the embodiment of the present invention. First, the user presses (trigger) the start switch 150 and transmits a start signal EN to the controller 120 (S210). Next, the controller 120 sends a control signal to conduct the energization element switch 110 (S220). The controller 120 transmits a reset command through the platform control hub 130 to cause the optical access medium 140 to perform a reset action (S230). Then, the controller 120 delays the enable signal EN to generate the virtual enable signal DEN, and the controller 120 directly transmits the virtual enable signal DEN to the optical access medium 140 (S240). Finally, the optical access medium 140 is activated and exits its carrier tray in accordance with the received virtual enable signal DEN (S250).

Please refer to FIG. 3. FIG. 3 is a schematic diagram of a computer device 300 according to an embodiment of the present invention. The computer device 300 includes a power switch 310, a controller 320, a platform control hub 330, an optical access medium 340, and a start switch 350. Unlike the computer device 100 of the previous embodiment, the start switch 350 of the computer device 300 is connected to the ground voltage GND through a pull-down resistor R2. That is to say, in the present embodiment, when the start switch 350 is not triggered, a zero level signal that is pulled down by the ground voltage GND through the pull-down resistor R2 is provided. When the start switch 350 is triggered, a positive pulse enable signal EN is provided.

In summary, the present invention utilizes a simple delay delay signal generated by the user to activate the switch, and accordingly generates a virtual enable signal. The virtual enable signal is then used to transmit directly to the optical access medium such that the optical access medium is activated and exits its carrier. In this way, complex software programs are not required to cooperate, and only a simple time delay function is required to generate the required virtual enable signal. Effectively reduce the burden on the system.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
