Detailed Description
Specific embodiments of the present invention will be described in more detail below with reference to the drawings. Advantages and features of the invention will become more apparent from the following description and claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the invention.
Referring to fig. 1 and 2, fig. 1 is a block diagram showing a portable computing device (hereinafter referred to as a "portable computing device") 1 for high-frequency operation in a mobile power supply mode according to a preferred embodiment of the present invention; fig. 2 is a schematic perspective view showing a portable computing device 1 according to a preferred embodiment of the invention. A portable computing device 1 comprises a power collecting module 11, a built-in battery module 12 storing a built-in power, an embedded controller 13, a switching module 14, a central processing unit (Central Processing Unit, CPU) 15 and a graphics processor (Graphics Processing Unit, GPU) 16. The power collecting module 11 further includes a power collecting unit 111 and a power distributing unit 112, and the switching module 14 further includes a switching unit 141 and a power supply amount reducing unit 142.
In the present embodiment, the portable computing device 1 is a notebook computer with a computing device identification code, but not limited thereto. The portable computing device 1 receives a mains power in a mains power mode and operates at a standard operating frequency, and receives a built-in power in a built-in battery power mode and operates at a power saving operating frequency lower than the standard operating frequency. The standard operating frequency and the power-saving operating frequency are average values of the operating frequency of the CPU15 and the operating frequency of the GPU 16. In the standard working frequency, the working frequency of the CPU15 is the first CPU working frequency, and the working frequency of the GPU16 is the first GPU working frequency; in the power saving operation frequency, the operation frequency of the CPU15 is a second CPU operation frequency lower than the first CPU operation frequency, and the operation frequency of the GPU16 is a second GPU operation frequency lower than the first GPU operation frequency.
When the portable computing device 1 is electrically connected to a portable power source device 2 provided with a power source device identification code, the control module 22 of the portable power source device 2 generates a movement control signal when the computing device identification code is judged to be a boost power source code. The switching module 23 receives the movement control signal, and switches on the battery module 21, so as to transmit the mobile electric energy stored in the battery module 21 to the portable computing device 1. In the present embodiment, the switching module 23 firstly transmits the mobile electric energy to the boost circuit 24, and boosts the mobile electric energy into a boosted electric energy through the boost circuit 24, and then transmits the boosted electric energy to the portable computing device 1, but not limited thereto.
When the power collecting unit 111 of the portable computing device 1 receives the boosted power and the embedded controller 13 determines the power supply device identification code, the portable computing device 1 is switched to operate at a mobile operating frequency in a mobile power supply mode. At the mobile operating frequency, the operating frequency of the CPU15 is the first CPU operating frequency, and the operating frequency of the GPU16 is a third GPU operating frequency. The third GPU operating frequency is between the first GPU operating frequency and the second GPU operating frequency, so that the mobile operating frequency is between the standard operating frequency and the power-saving operating frequency.
In the present embodiment, the portable computing device 1 is electrically connected to the portable power device 2 through a power line 3 and a transmission line 4, but not limited thereto. The portable computing device 1 receives portable electric power via the power line 3, but the portable electric power may be received by a wireless power supply reception system without limitation. In addition, the embedded controller 13 reads the power supply device identification code through the transmission line 4, but not limited to this, and may also adopt a reading mode such as wireless transmission, bluetooth (Bluetooth), near-field communication (NFC) and wireless radio frequency identification system (Radio Frequency Identification, RFID).
After the portable computing device 1 is switched to operate at a mobile operating frequency, the embedded controller 13 further determines the remaining power of the built-in power, and determines the remaining power of the built-in power as the prior art, which is not described herein. When the remaining power is higher than a synchronous power reference value, a control signal is generated and transmitted to the switching unit 141 in the switching module 14. When the switching unit 141 receives the control signal, it switchably turns on the built-in battery module 12 to transmit the built-in power to the power supply amount reducing unit 142 also in the switching module 14. The switching unit 141 may be a switch, but is not limited thereto.
After receiving and conditioning the built-in electric energy, the power supply conditioning unit 142 transmits the built-in electric energy to the electric energy collection unit 111, and the mobile electric energy and the built-in electric energy are collected into a collected electric energy through the electric energy collection unit 111, and the collected electric energy is transmitted to the electric energy distribution unit 112, so that the portable computing device 1 is lifted to operate at the standard working frequency in the mobile power supply mode. The problem that the portable computing device 1 cannot operate in a standard work mode under a non-mains supply mode in the prior art is solved. The power supply amount reducing unit 142 may be a variable resistor, but not limited to, a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) transistor. In addition, the power supply amount adjusting unit 142 may be a fixed adjustment or a variable adjustment. The fixed type regulating and lowering is to regulate and lower the built-in electric energy to a certain fixed value, and the fixed value is fixed and unchanged; the variable power-down is to adjust the built-in power to a certain reference value, but the reference value can be operatively changed according to the user's set requirement or according to the portable computing device 1.
The Power collection unit 111 may be a bus, and the Power distribution unit 112 may be a Power supply (Power supply), but is not limited thereto.
When the remaining power is not higher than the synchronous power reference value, the switching unit 141 will not turn on the built-in battery module 12, so that the portable computing device 1 operates at a mobile operating frequency in a mobile power mode, thereby enabling the portable computing device 1 to simultaneously achieve both the operating efficiency and the service time of the portable computing device 1 (i.e. so-called extension of the power supply time of the mobile power and the built-in power).
In addition, when the portable computing device 1 is in the non-external power supply mode (the mains supply mode and the mobile power supply mode), the embedded controller 13 generates a second control signal, the switching unit 141 receives the second control signal to switchably conduct the built-in battery module 12 and the power collecting unit 111, and the built-in power of the built-in battery module 12 is directly transmitted to the power collecting unit 111 without passing through the power supply amount reducing unit 142. Therefore, after the power distribution unit 112 receives the built-in power, the portable computing device 1 will switch to operate at the power-saving operating frequency in the built-in battery power mode.
The following will be an example of the embodiment of the portable computing device 1 provided in the present invention in practical use, so that the present invention can be more easily understood.
Generally, the total wattage required for a low and medium-grade notebook computer to operate in a standard operating frequency in a mains power mode is about 130 to 150 watts (140 watts for example). The mobile power supply device generally provides up to 100 watts (100 watts for example). When the notebook computer is operated in the built-in battery power mode at a power saving operating frequency, the total wattage provided by the built-in battery is about 60 to 80 watts (for example, 70 watts).
When the notebook computer is electrically connected with the mobile power supply device, the mobile power supply device receives 100 watts of mobile power and operates at a mobile working frequency in a mobile power supply mode. The notebook computer further determines whether the remaining power of the built-in battery is higher than the synchronous power supply reference value (30% or 40% is different, and can be set according to the requirement of the user), if yes, the built-in battery is turned on, so that the built-in battery transmits 70 watts of built-in power. The total wattage required for the notebook computer to operate at the standard operating frequency is 140 watts, so that 70 watts of built-in power is transferred to the power supply amount adjusting unit 142, and 70 watts of built-in power is adjusted to 40 watts by the power supply amount adjusting unit 142 and transferred to the power collecting unit 111.
When the power collection unit 111 receives the 40 w of built-in power, it collects the 40 w of built-in power and the 100 w of mobile power into a 140 w of collected power, and transmits the 140 w of collected power to the power distribution unit 112. Therefore, the notebook computer receives 140 watts of collected power, so that the notebook computer can operate at a standard working frequency in a mobile power supply mode.
In addition, the power 30% is used as the synchronous power supply reference value and the boundary between the high power and the low power, if the power of the notebook computer is higher than 30% and the power of the mobile power supply device is lower than 30%, the notebook computer judges that the residual power of the built-in battery is higher than the synchronous power supply reference value, so that the notebook computer operates at the standard working frequency in the mobile power supply mode. The above-mentioned situation is that the notebook computer is self-judged and does not involve the manual judgment of the user, but involves the manual judgment of the user in actual use. Because the notebook computer and the portable power source device are inconvenient for the user if one of the electric quantity is exhausted, the user may charge the portable power source device during the actual use, and the notebook computer is switched to operate at the power-saving working frequency in the built-in battery power supply mode. However, if the user finds that the power of the mobile power supply is lower than 30% and does not take any action, the notebook computer still operates at the standard operating frequency in the mobile power supply mode.
Next, referring to fig. 1 and fig. 3 together, fig. 3 is a flowchart showing a method for operating a portable computing device at high frequency in a mobile power mode according to a preferred embodiment of the invention. As shown in the drawings, the preferred embodiment of the present invention provides a method for operating a portable computing device at high frequency in a mobile power mode.
First, in the mobile power supply mode, the portable computing device 1 receives mobile power supplied from the mobile power supply device 2 provided with the power supply device identification code, and switches to operate at the mobile operating frequency after determining the power supply device identification code by the embedded controller 13 (i.e., step S101).
In the present embodiment, the portable computing device 1 is electrically connected to the portable power device 2 through a power line 3 and a transmission line 4, but not limited thereto.
Next, the embedded controller 13 further determines that the residual power of the built-in power is higher than the synchronous power supply reference value, and generates a control signal (i.e. step S102). When the switching module 14 receives the control signal, it switchably connects the built-in battery module 12 and the power collecting module 11, thereby transmitting the built-in power to the power collecting module 11 (step S103).
Finally, the power collection module 11 collects the mobile power and the built-in power into collected power after receiving the built-in power, so that the portable computing device 1 is lifted to operate at the standard operating frequency in the mobile power supply mode (step S104).
In summary, in the portable computing device and the operating frequency increasing method thereof operating at high frequency in the mobile power supply mode provided by the invention, the embedded controller is configured to determine the power supply device identification code when the power collecting module receives the mobile power. And further judging that a residual electric energy of the built-in electric energy is higher than a synchronous power supply reference value, generating a control signal so as to enable the switching module to switchably conduct the built-in battery module and the electric energy collection module and transmit the built-in electric energy to the electric energy collection module.
The electric energy collection module collects the built-in electric energy and the mobile electric energy into a collected electric energy, so that the portable computing device can be switched to operate at the standard working frequency in the mobile power supply mode, and the problems that in the prior art, the operation efficiency of a CPU (Central processing Unit) and a GPU (graphics processing Unit) cannot be effectively improved under the condition of non-commercial power supply (including a built-in battery power supply mode and a mobile power supply mode) are solved.
In view of the foregoing detailed description of the preferred embodiments, it is intended that the features and spirit of the invention be more clearly described rather than limiting the scope of the invention as defined by the foregoing description of the preferred embodiments. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.
