Said USB unit comprises USB1.1, USB2.0, three kinds of transmission modes of USB3.0, and the control signal in order to produce according to said controller provides different transmission modes to said electronic installation;
Said controller according to the reduction process of power supply power supply energy, produces control signal in order to monitor the power supply energy of said power supply, and control USB carries out the switching of transmission mode to the order of USB1.1 according to USB3.0 to USB2.0 in the unit again.
Further, said controller is provided with the related information of first predetermined threshold, second predetermined threshold and said power supply energy, and said first predetermined threshold is greater than second predetermined threshold.
Further, said controller also comprises comparer, in order to compare power supply energy related information and first predetermined threshold and second predetermined threshold:
When the related information of said power supply energy greater than said first predetermined threshold time, work under the USB3.0 transmission mode in the USB unit;
When the related information of said power supply energy during less than said first predetermined threshold and greater than second predetermined threshold, work under the USB2.0 transmission mode in the USB unit;
When the related information of said power supply energy less than said second predetermined threshold time, work under the USB1.1 transmission mode in the USB unit.
Further, the related information of said power supply energy is DC voltage.
Further, first predetermined threshold is that 75%, the second predetermined threshold of the related information of initial power supply energy is 25% of the related information of initial power supply energy.
Further, said threshold value is a threshold voltage, perhaps is current value, internal resistance of cell value.
Compare with traditional electronic installation; The electronic installation that the present invention proposes adopts different transmission modes through the power supply energy of monitoring power supply output under different power supply energies, when power supply energy is relatively more sufficient; The power supply energy value is than higher, works under the USB3.0 transmission mode in the USB unit; After power supply energy reduced, the power supply energy value decreased, and worked under the USB2.0 transmission mode in the USB unit; When power supply energy was very small, the power supply energy value was lower, worked under the USB1.1 transmission mode in the USB unit, thereby can satisfy the demand of high-speed transfer, also can prolong the service time of battery.
Description of drawings
Fig. 1 is the structural representation of electronic installation in the embodiment of the invention.
Embodiment
For clearer understanding technology contents of the present invention, the special specific embodiment of lifting also cooperates appended graphic explanation following.
See also Fig. 1, Fig. 1 is the electronic device construction synoptic diagram in the embodiment of the invention, and this electronic installation comprises power supply 2, controller 1 and USB unit 3, and said power supply 2 usefulness think that said electronic installation provides power supply energy; Said controller 1 is in order to monitor the power supply energy of said power supply 2; And according to the power supply energy of power supply 2; Produce control signal, the transmission mode of control USB unit 3 is carried out exchanges data, transmission etc. through other equipment or unit in USB interface 4 and the electronic installation.
Present portable set; Most popular data transmission standard is the USB standard; Continual renovation along with technology; The USB standard is also constantly being improved, the transmission mode of the USB1.1 that releases one after another, USB2.0, USB3.0, and the USB unit 3 in the present embodiment comprises USB1.1, USB2.0, three kinds of transmission modes of USB3.0.Control signal according to said controller produces in actual use, according to the power supply energy of said power supply 2, provides different transmission modes to said electronic installation.
Be provided with the information of first predetermined threshold, second predetermined threshold in the said controller 1; Promptly in controller 1, preserve the threshold value of first predetermined threshold, the threshold value of second predetermined threshold through program design; The related information of said power supply energy be the power supply energy of controller 1 monitoring power supply 2 and obtain threshold value; Compare through the comparer in the controller 1 (not indicating), in the present embodiment, described threshold value is that example describes with the magnitude of voltage.Certainly; Threshold value described in the present invention is not limited to magnitude of voltage; As long as the variation of the various parameters that cause according to the variation of power supply energy state; The threshold value that is provided with according to the variation of various parameters is such as the variation of the internal resistance of source, the variation of current value etc., all in concept of the present invention.
The threshold value that with the magnitude of voltage is present embodiment below is that example is set forth the present invention; The threshold value that is present embodiment is a threshold voltage; Set the first predetermined threshold magnitude of voltage and be 75% of initial supply voltage; The second predetermined threshold magnitude of voltage is 25% of an initial supply voltage, can certainly set the first predetermined threshold magnitude of voltage and the second predetermined threshold magnitude of voltage and be other values according to user's demand.
When charge electronic devices finishes, when perhaps transferring direct current supply to by interchange, the power supply that promptly provides this moment is from battery; Energy is in state of saturation, and the magnitude of voltage that provides is the highest, and this moment, its operational voltage value was greater than the said first predetermined threshold magnitude of voltage; Work under the USB3.0 transmission mode in the USB unit, the electric weight that electronic installation provides through bus is 900 milliamperes, and transfer rate is 5.0Gbps; The transfer efficiency of this moment is very high, can bring into play the performance of electronic installation fully.
Through after work a period of time; The energy consumption of battery is fallen a part; The magnitude of voltage that provides obviously reduces, when supply voltage value during less than the said first predetermined threshold magnitude of voltage and greater than second predetermined threshold, if continue to let electronic installation under the USB3.0 transmission mode, work this moment; The USB3.0 transmission mode since transfer rate up to 5.Gbps, speed is fast, efficient is high.Though its transfer rate is very fast, for battery 2, during high-speed transfer, consume very soon, shorten service time of battery greatly.And the great talent of its bus-powered electric current of USB2.0 is 500 milliamperes, and transfer rate is 480Mbps, for general product; Speed satisfies the demands, and therefore, adopts the USB2.0 transmission mode this moment; Not only satisfy rate request, and cut down the consumption of energy, can delay the service time of battery.
Battery continues to use again, and the energy content of battery is considerably less, and the power supply energy value is lower; When said power supply energy value during less than said second predetermined threshold; Working current under the USB2.0 pattern that this moment, battery was difficult to provide can switch to its transmission mode under the USB1.1 pattern through the control of controller; Because its bus-powered electric current of USB1.1 is about 100 milliamperes; Transfer rate is 12Mbps, so still can work on a period of time, thereby is convenient to prolong the service time of electronic installation.
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
