Embodiment
Fig. 1 is a kind of GPS navigation schematic representation of apparatus of the present invention.Please refer to Fig. 1, GPS navigation device 100 provided by the present invention can have a power-saving working mode, this power-saving working mode can GPS navigation device 100 be in unused state a period of time after, can make the system hibernates of GPS navigation device 100, to save the electric power of GPS navigation device 100.At length, after GPS navigation device 100 was opened, if its navigation feature is not activated, then the navigation information that sends from Navsat need not be searched and receive to GPS navigation device 100, also do not need show navigator information.When a Preset Time was not operated GPS navigation device 100 if the user is separated by again, then GPS navigation device 100 will enter the power-saving working mode operation.At this moment, electric power required when GPS navigation is adorned required electric power and can more normally be operated is little, so GPS navigation just can be saved electric power effectively.In general, when the navigation feature of GPS navigation device 100 was activated, then its power-saving working mode can be by forbidden energy.
In addition, GPS navigation device 100 comprises a processing unit 110, an output unit 120 1 power interfaces 130.Wherein, output unit 120 and power interface 130 all electrically connect with processing unit 110, and the processing unit 112 of present embodiment except the operation result with navigation information offer output unit 120 output, whether the navigation feature that also can detect GPS navigation device 100 is activated, with the power-saving working mode of automatic forbidden energy or activation GPS navigation device.Output unit 120 for example is a display screen, and it allows the user correctly and promptly arrive the destination according to navigation information in order to display processing unit 110 handled navigation informations.In addition, GPS navigation device 100 is suitable for being linked to a power supply 200 by power interface 130 and keeps electric power, allows the user when using the navigation feature of GPS navigation device 100, and output unit 120 is show navigator information constantly.In the present embodiment, for example be GPS navigation device 100 to be linked to power supply 200, or the GPS navigation device is linked to AC power or direct supply, for example power supply on vehicle etc. by the battery of changing GPS navigation device 100.
Because GPS navigation device 100 quite expends electric power when display processing unit 110 handled navigation informations, therefore the present invention proposes a kind of operating mechanism of GPS navigation device in addition, it can decide the power-saving working mode of forbidden energy or activation GPS navigation device 100 according to the detecting of processing unit 110, to save the electric power of GPS navigation device 100 when navigation information is provided.Fig. 2 is the operating mechanism flow process of the GPS navigation device of Fig. 1.Please refer to Fig. 2, start the navigation feature of GPS navigation device 100 as the user after, whether the navigation feature that processing unit 110 can detect GPS navigation device 100 is activated.If the navigation feature of GPS navigation device 100 is activated, then processing unit 110 is understood the power-saving working mode of forbidden energy GPS navigation devices 100, so that GPS navigation device 100 can continue and navigate normally.Changing speech, promptly is the power-saving working mode that processing unit 110 can be closed GPS navigation device 100.
After, processing unit 110 can continue the state of charge of detecting GPS navigation device 100.When processing unit 110 detects GPS navigation device 100 is (step S110) when hanging down state of charge, processing unit 110 can be opened the power-saving working mode (step S120) of (activation) GPS navigation device 100 again, make display unit 120 stop show navigator information, to save the electric power of GPS navigation device 100.
On the other hand, whether processing unit 110 can be linked to power supply 200 (step S130) by detecting GPS navigation device 100.Suppose, when the user learns that by this incident that display unit 120 stops show navigator information GPS navigation device 100 is in low state of charge, and when GPS navigation device 100 was linked to power supply 200 by power interface 130, processing unit 110 can detect the incident that GPS navigation device 100 is linked to power supply 200 and take place.Therefore, processing unit 110 can be closed the power-saving working mode (step S140) of (forbidden energy) GPS navigation device 100 again, allows display unit 120 show navigator information again.At this moment, because GPS navigation device 100 has been linked to power supply 200, so the processing unit 110 of GPS navigation device 100 has enough electric power and handles the navigation information that is received, and makes display unit 120 continue the show navigator information.
In sum, GPS navigation device of the present invention is after the user starts its navigation feature, the state of charge of processing unit meeting Auto-Sensing GPS navigation device, and the state of charge that foundation is detected decides the power-saving working mode of opening or closing the GPS navigation device.And the operating mechanism of GPS navigation device can detect after the GPS navigation device has been linked to power supply at processing unit, allows the processing unit power-saving working mode of forbidden energy (closing) GPS navigation device again, allows display unit continue show navigator information.For the user, the power-saving working mode of GPS navigation device can be opened or close to GPS navigation device of the present invention and operating mechanism thereof automatically, to save the electric power of GPS navigation device, not only have ease of use, and the GPS navigation device also can have long service time.
