Charging single 160 includes charge integrated circuit 161 and charging indicator light 162, and it can pass through such as USB Charger (not shown) is connected to external power source and is charged.Certainly, battery 150 and charhing unit 160 Can also be positioned at outside location equipment 100.

Below by the operation principle of exemplary description location equipment 100.

Power control unit 130 has normal mode of operation and standby mode.Power control unit 130 1 Directly remain powered up, unless battery electric power exhausts.In the normal mode of operation, power control unit 130 Export the first control signal by the first control output end PWR_CTL and make the first switching device 170 (such as For PMOS) conducting, thus with voltage VBATIN for communication unit 120 and satellite positioning unit 110 Power supply.In most of the cases, power control unit 130 may be in normal mode of operation, such as When location equipment 100 inserts charger or when battery 160 has enough electricity, voltage VBAT triggers Power control unit 130 enters normal mode of operation.Under certain condition, such as arrive certain specific time Between section (such as point at 9 in evening to morning next day 9) or enter certain specific region (such as get home or School), power control unit 130 can enter the standby mode of low-power consumption, now the first switching device 170 turn off, thus communication unit 120 and satellite positioning unit 110 power failure, and this will enter one after a while Step discusses in detail.

Communication unit 120 has normal mode of operation, park mode and power-down mode.At normal Working mould In formula, communication unit 120 is gathered positional information by satellite positioning unit 110 and is incited somebody to action by mobile network Positional information uploads to location-server (not shown).

First power control unit 130 is discussed and is in the situation under normal mode of operation.

In one embodiment, communication unit 120 includes first timer (not shown), the first timing Device set satellite positioning unit 110 and gathers the very first time interval of positional information, such as five minutes.First Timer expire (i.e. through the very first time be spaced) time, the communication unit 120 being under normal mode of operation Satellite positioning unit control signal is sent to satellite positioning unit 110 by control output end VGPS_CTL Open satellite positioning unit 110.In FIG, satellite positioning unit control signal is sent to and satellite The second switch device 180 that positioning unit 110 is connected, this second switch device 180 turns on, thus satellite Positioning unit 110 obtains power supply and starts working.Satellite positioning unit 110 carries out satellite fix and incites somebody to action Positional information is sent to communication unit 120.Communication unit 120 also includes buffer, for storage from satellite The positional information that positioning unit 110 receives.Communication unit 120, with such as SIM, can receive Through positional information being reported immediately location-server by antenna after positional information.After having reported, logical Letter unit 120 can enter the park mode of low-power consumption.Satellite positioning unit 110 is sending position letter Can automatically shut power off after breath, or communication unit 120 can receive from satellite positioning unit 110 To positional information or after positional information is reported location-server, pass through control output end VGPS_CTL sends shutdown signal and closes satellite positioning unit 110.When again passing by between the very first time Every time, communication unit 120 and satellite positioning unit 110 repeat said process, thus gather new position Information.So, satellite positioning unit 110 is closed not carrying out satellite fix when, and Communication unit 120 is in the holding state of low-power consumption need not upload location information when, to save Electric power.Additionally, satellite positioning unit 110, such as model are the GPS chip of UBX7020, can have Having single real-time clock (RTC) power supply, this electric power is provided by telecommunication circuit 120, though communication electricity Road 120 is in a dormant state.Existence due to this RTC power supply, it is ensured that satellite positioning unit every time 110 open after can be with fast search to satellite, positioning time may be and electric at RTC about the 2-3 second Source does not power in the case of (such as telecommunication circuit is fully powered off), and satellite positioning unit 110 is being opened The time that can require over 20 seconds after opening could obtain location.Certainly, satellite positioning unit 110 also may be used Only just to close need not location when rather than to close after location every time.Such as, right Under the scene that the requirement of real-time of positional information is higher, such as when footwear be in the other region of low level security (as Street) time, then satellite positioning unit 110 can be always maintained at open and constantly offer positional information to Communication unit 120.The option closing satellite positioning unit 110 can set in communication unit 120, Such as close immediately after the position data every time receiving satellite positioning unit 110, by positional information Close after reporting location-server, do not close within one period of scheduled time or do not close.This choosing Communication unit 120 can be set according to occasion, the position such as location equipment 100 by item by location-server Fixed.In addition to satellite positioning unit 110 carries out satellite fix, communication unit 120 can also assist Location, such as, A-GPS, it utilizes the base station of mobile network to position.Auxiliary positioning is due to by base Stand firm position, therefore precision not as satellite fix high, but locating speed is fast.Auxiliary positioning coordinates satellite fix Positioning time can be shortened, the most such as, can use a satellite fix and the most auxiliary within a period of time Help location.It addition, when location equipment enters specific region (such as the indoor) of satellite fix difficulty, can With only with auxiliary positioning.Satellite fix can be positioned by communication unit control with the switching of auxiliary positioning Server can also use instruction to be controlled by communication unit.

In another embodiment, communication unit 120 can also include second timer (not shown), Second timer sets the second time interval of communication unit 120 upload location information.Second time interval It is spaced more than the very first time, preferably the integral multiple at very first time interval, such as 30 minutes.Second Timer expire (i.e. through the second time interval) time, the position that communication unit 120 will be accumulated in buffer Confidence breath reports server together.So, a plurality of positional information one can be risen by communication unit 120 Give server, such that it is able to save flow and electric power that communication process is consumed.

The very first time is spaced when can dispatch from the factory with the second time interval or user pre-sets.Or Person, very first time interval and the second time interval can also be arranged by server.Such as, when judging location When equipment 100 enters safety zone (such as family or school), server can increase very first time interval With the second time interval, i.e. reduce and gather and the frequency of reporting position information, to save electric power.Work as judgement When location equipment 100 enters the other region of low level security (such as street), when server can reduce first Between interval and the second time interval, i.e. increase and gather and the frequency of reporting position information, with obtain more and The positional information that real-time is higher.

When the second time interval is shorter, such as, the second time interval is within 2 hours, i.e. A positional information is reported, then utilize the above-mentioned two timer of communication unit 120 to enter less than 2 hours Row power consumption control is suitable, and communication unit 120 is in normal mode of operation or park mode.For Two time intervals are longer, such as the threshold value more than 2 hours, then above-mentioned two timer can be by electric power Control unit 130 configures, because the use frequency of communication unit 120 is the lowest in this case, and electric power Control unit 130 can control the first switching device 170 by the first control output end 132 and turn off, from And make communication unit 120 power-off to save electric power.Any instruction cannot be received after communication unit 120 power-off, Now the first and second timers should be arranged in power control unit 130, i.e. power control unit 130 include the first and second timers, are used for controlling sequential, when corresponding timer expires, and electric power control Unit 130 processed controls the first switching device 170 by the first control output end 132 and turns on and perform accordingly The collection of positional information or upload.The first and second timers in communication unit 120 (if having Words) can be deactivated.This mode by communication unit power-off is not suitable for the feelings that the second time interval is shorter Condition, because having bigger electric current when that communication unit starting after a loss of power, if Switch Communication frequently Module can increase power consumption on the contrary.Certainly, power control unit 130 is the most all used to control Sequential is also possible, when communication unit 120 is in the park mode of low-power consumption, and power control unit 130 can pass through the second control output end WAKE_UP to communication unit when corresponding timer expires 120 output the second control signals wakes up communication unit 120 up, perform corresponding positional information collection or on Pass.

Communication unit 120 can first be connected with location-server after waking up up from resting state or start every time Alternately, reporting the current state of oneself, location-server decides whether on communication unit 120 Pass positional information.It is said that in general, the SECO in communication unit 120 and power control unit 130 is adopted By the form of relative time, location equipment may produce time migration after a certain period of use time.One In individual embodiment, location-server can periodically or be used definitely when being connected with communication unit 120 every time In time synchronized communication unit 120 and power control unit 130, with correction time.

In one embodiment, in order to save electric power further, power control unit 130 can also be one Control the first switching device 170 by the first control output end 132 under fixed condition to turn off, so that communication Module 120 and satellite positioning unit 110 power-off.Power control unit 130 oneself enters treating of low-power consumption Machine pattern.The specified conditions entering standby mode such as include, the second time interval as above is longer Situation, after communication unit 120 uploads positional information, distance upload to location-server next time The interval of positional information is longer (such as more than 2 hours), and power control unit 130 can make communication unit 120 and satellite positioning unit 110 power-off.In addition it is also possible to set according to the application scenarios of location equipment 100 These specified conditions fixed.Such as, above-mentioned location equipment 100 being positioned to the scene of sole part, entrance is treated The condition of machine pattern can include arriving certain special time period (such as point at 9 in evening to morning next day 9) Or entering certain specific region, specific region includes the region that level of security is high, such as family or school.
