Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in accompanying drawing, but should be appreciated that and can realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order more thoroughly to understand the disclosure that these embodiment are provided, and can be by the those skilled in the art that conveys to complete the scope of the present disclosure.
Fig. 1 shows the circuit diagram of positioning equipment 100 according to an illustrative embodiment of the invention.
As shown in Figure 1, positioning equipment 100 comprises satnav unit 110, communication unit 120, power control unit 130, motion sensor 140.Positioning equipment 100 can be positioned in the various article that are intended to obtain its position.For example, the positional information that the head of a family may wish to obtain children is to prevent from wandering away or in unsafe conditions, 100 of this positioning equipments can be positioned in children's sole part.The current anti-bracelet of wandering away is limit due to space and electric power, does not adopt satnav, but only uses GSM network positions.In contrast to this, the space of sole part is much bigger, thereby can allow to use satnav and hold larger battery, and accurate, lasting location is followed the tracks of becomes possibility.
Satnav unit 110 is for the position of positioning equipment 100.Typically, satnav unit 110 is GPS chips, and for example model is UBX7020, adopts the encapsulation of QFN40 microminiature, and 40 pins, support the engine of positioning such as GPS, GOLNASS, has high sensitivity and capture time fast, contributes to realize fast location.Certainly, can be also the chip of supporting other global position systems such as the Big Dipper.Communication unit 120 is for sending to location-server by the positional information of positioning equipment 100.Typically, communication unit 120 is GSM chip or the CDMA chips that adopt SOC design, for example, MTK6260D, it utilizes GPRS link that positional information is sent to location-server by mobile cellular network, and can receive dependent instruction from the latter.Location-server can be for example the Cloud Server that stores map, and the head of a family can download and install position application, is obtained positional information and sees such as child's current place, the place of once going etc. at map from server by this application.
The GSM chip of employing SOC above-mentioned design is often integrated in GSM radio frequency unit, baseband processing unit, storer, power discharging device etc. on a chip, there is voice call, send all basic functions that SMS messaging, GRPS data transmission etc. communicate based on GSM network, therefore be widely used in entry level mobile phone, cost is low, and reliability is strong.But many just because of the function of this integrated chip, therefore power consumption is higher, if keep it to power up, even also can consumes considerable electric power in the situation that not carrying out data transmission, thereby form bottleneck for the limited positioning equipment of battery capacity.
According to design of the present invention, propose to utilize power control unit 130 to control the electric power of communication unit 120 and satnav unit 110, further, can realize more intelligent electric power control by routing motion sensor 140.Power control unit 130 is for example realized by single-chip microcomputer.
Positioning equipment 100 can also comprise battery 150, charhing unit 160 and the first switching device 170.Charhing unit 160 comprises charging integrated circuit 161 and charging indicator light 162, and it can be connected to external power source by for example USB charger (not shown) and charge.Certainly, battery 150 and charhing unit 160 also can be positioned at outside positioning equipment 100.
Below by the principle of work of exemplary description positioning equipment 100.
Power control unit 130 has normal mode of operation and standby mode.Power control unit 130 keeps powering state always, unless battery electric power exhausts.Under normal mode of operation, power control unit 130 is exported the first control signal by the first control output end PWR_CTL and is made the first switching device 170 (for example for PMOS) conducting, thus taking voltage VBATIN as communication unit 120 and satnav unit 110 power.In most of the cases, power control unit 130 can be in normal mode of operation, and for example, in the time that positioning equipment 100 inserts charger or when battery 160 has enough electric weight, voltage VBAT triggers power control unit 130 and enters normal mode of operation.Under certain condition, for example arrive certain special time period at (for example in evening to point in mornings 9 next day) at 9 or enter certain specific region (as getting home or school), power control unit 130 can enter the standby mode of low-power consumption, now the first switching device 170 turn-offs, thereby communication unit 120 and satnav unit 110 power failure, this will further discuss in detail after a while.
Communication unit 120 has normal mode of operation, park mode and power-down mode.In normal mode of operation, communication unit 120 positioning unit 110 collection position information positional information is uploaded to location-server (not shown) by mobile network via satellite.
First the situation of power control unit 130 under normal mode of operation be discussed.
In one embodiment, communication unit 120 comprises first timer (not shown), and first timer was set the very first time interval of satnav unit 110 collection position information, as five minutes.Expire (passing through very first time interval) during at first timer, the communication unit 120 under normal mode of operation sends the second control signal by control output end VGPS_CTL to satnav unit 110 and opens satnav unit 110.In Fig. 1, the second control signal is sent to the second switch device 180 being connected with satnav unit 110, these second switch device 180 conductings, thus 110 acquisitions of satnav unit are powered and are started working.Satnav unit 110 carries out satnav and positional information is sent to communication unit 120.Communication unit 120 also comprises impact damper, for storing the positional information receiving from satnav unit 110.Communication unit 120, with for example SIM card, can received after positional information through positional information being reported to location-server immediately by antenna.After having reported, communication unit 120 can enter the park mode of low-power consumption.Satnav unit 110 is sending after positional information powered-down automatically, or communication unit 120 can receive positional information or positional information be reported location-server from satnav unit 110, send shutdown signal by control output end VGPS_CTL and close satnav unit 110.When again passing through the very first time when interval, communication unit 120 and satnav unit 110 repeat said process, thereby gather new positional information.Like this, satnav unit 110 is in closed condition in not carrying out satnav, and communication unit 120 holding state in low-power consumption in not needing uploading position information, to save electric power.In addition, satnav unit 110, the GPS chip that for example model is UBX7020, can have independent real-time clock (RTC) power supply, and this electric power is provided by telecommunication circuit 120, even if telecommunication circuit 120 is in dormant state.Due to the existence of this RTC power supply, can ensure each satnav unit 110 can fast search after opening to satellite, positioning time may be about 2-3 second, for example, and do not power (telecommunication circuit by completely power-off) at RTC power supply in the situation that, satnav unit 110 may need to exceed time of 20 seconds and could obtain location after unlatching.Certainly, satnav unit 110 also can only just be closed in not needing location, instead of closes after each location.For example, under the higher scene of the requirement of real-time of location information, for example, when footwear are during in other region of low level security (as street), satnav unit 110 can be held open always and constantly provide positional information to communication unit 120 so.Closing the option of satnav unit 110 can set in communication unit 120, for example after the position data that at every turn receives satnav unit 110, close immediately, after positional information is reported to location-server, close, within one period of schedule time, do not close or do not close always.This option can be by location-server according to occasion, as the position of positioning equipment 100 set by communication unit 120.Except satnav unit 110 carries out satnav, communication unit 120 can also carry out auxiliary positioning, for example, A-GPS, it utilizes mobile network's base station to position.Auxiliary positioning is due to by architecture, therefore precision not as satnav high, but locating speed is fast.Auxiliary positioning coordinates satnav can shorten positioning time, therefore for example can within a period of time, adopt satnav and auxiliary positioning repeatedly.In addition, in the time that positioning equipment enters the specific region (as indoor) of satnav difficulty, can only adopt auxiliary positioning.The switching of satnav and auxiliary positioning can be by communication unit control, and location-server also can adopt instruction to control by communication unit.
In another embodiment, communication unit 120 can also comprise second timer (not shown), and second timer is set second time interval of communication unit 120 uploading position information.Second interval greater than very first time interval, and the preferably integral multiple at very first time interval, as 30 minutes.Expire (through second time interval) during at second timer, the positional information of accumulating in impact damper is reported together server by communication unit 120.Like this, communication unit 120 can send to server together by many positional informations, thereby can save flow and electric power that communication process consumes.
When very first time interval and second time interval can dispatch from the factory or user set in advance.Or very first time interval and second time interval also can be by Servers installeds.For example, in the time judging that positioning equipment 100 enters safety zone (as family or school), server can increase very first time interval and second time interval, reduces the frequency of collection and reporting position information, to save electric power.In the time judging that positioning equipment 100 enters other region of low level security (as street), server can reduce very first time interval and second time interval, increase the frequency of collection and reporting position information, to obtain the more and stronger positional information of real-time.
For shorter situation of second time interval, for example, second time interval is in 2 hours, less than within 2 hours, reporting one time positional information, it is suitable utilizing so above-mentioned two timers of communication unit 120 to carry out power consumption control, and communication unit 120 is in normal mode of operation or park mode.Longer for second time interval, for example exceed the threshold value of 2 hours, so above-mentioned two timers can be configured by power control unit 130, because the frequency of utilization of communication unit 120 is very low in this case, power control unit 130 can be controlled the first switching device 170 by the first control output end 132 and turn-off, thereby makes communication unit 120 power-off to save electric power.After communication unit 120 power-off, cannot receive any instruction, now the first and second timers should arrange in power control unit 130,, power control unit 130 comprises the first and second timers, be used for controlling sequential, in the time that corresponding timer expires, power control unit 130 is controlled the first switching device 170 conductings and is carried out the collection of corresponding positional information or upload by the first control output end 132.The first and second timers (if any) in communication unit 120 can be deactivated.This mode by communication unit power-off is not suitable for shorter situation of second time interval, because communication unit has larger electric current in starting after power-off, if switch communication module can increase power consumption on the contrary frequently.Certainly, all adopting in both cases power control unit 130 to control sequential is also fine, when park mode at communication unit 120 in low-power consumption, power control unit 130 can be exported the second control signal by the second control output end WAKE_UP to communication unit 120 and wake communication unit 120 up in the time that corresponding timer expires, and carries out the collection of corresponding positional information or uploads.
Communication unit 120 at every turn from dormant state wake up or start can first be connected with location-server and mutual, report the current state of oneself, location-server determines whether needing communication unit 120 uploading position information.Generally speaking, the sequential control in communication unit 120 and power control unit 130 adopts the form of relative time, and positioning equipment is using after certain hour and may be offset by generation time.In one embodiment, location-server can regularly or in the time being connected with communication unit 120 be used in Absolute Time Synchronization communication unit 120 and power control unit 130, with correction time at every turn.
In one embodiment, in order further to save electric power, power control unit 130 can also be controlled the first switching device 170 by the first control output end 132 under certain condition and turn-off, thereby makes communication module 120 and 110 power-off of satnav unit.Power control unit 130 oneself enters the standby mode of low-power consumption.The specified conditions that enter standby mode for example comprise, the situation that second time interval as above is grown, upload after positional information at communication unit 120, distance is grown (as more than 2 hours) to the interval of location-server uploading position information next time, and power control unit 130 can make communication unit 120 and 110 power-off of satnav unit.In addition, also can set these specified conditions according to the application scenarios of positioning equipment 100.For example, be positioned at the scene of sole part for above-mentioned positioning equipment 100, the condition that enters standby mode can comprise and arrives certain special time period at (for example in evening to point in mornings 9 next day) at 9 or enter certain specific region, specific region comprises the region that level of security is high, as family or school.In this special time period or specific region, child has probably taken off shoes, therefore need not continue to monitor its position.Power control unit 130 can comprise standby period timer, for setting this special time period.Communication module can receive the instruction that standby period timer is set from location-server, and in the time arriving particular moment, power control unit 130 enters standby mode automatically.Or, server can send and make power control unit 130 enter the instruction of standby mode to communication module in the time judging that arrival particular moment or positioning equipment 100 enter specific region, communication module receives this instruction, thereby power control unit 130 enters standby mode.Communication module can receive and enter the prompting of specific region and this prompting is sent to electrical management module about positioning equipment from location-server, or receives about making power control unit enter the instruction of standby mode from location-server in the time that location-server determines that positioning equipment enters specific region.
In one embodiment, can also be equipped with motion sensor 140 realizes more intelligent energy-conservation.Motion sensor 140 keeps work always, even if power control unit 130 has entered standby mode.Motion sensor 140 for example comprises gravity sensor.In the above example, Gravity changer means the motion of shoes, and child may put on shoes and walk about, and now can recover monitoring.When sensing when motion, motion sensor 140 sends the 3rd control signal to power control unit 130, the latter is waken up and enters into normal mode of operation from standby mode, the collection of enable position information and uploading.For fear of wrong report, after being waken up, power control unit 130 can first be carried out the certain reflection of motion of deterministic process sensing to determine and walk about normally, instead of shoes are accidentally moved.For example can add up interior motion/displacement variable of a period of time (as 30 seconds) that motion sensor 140 provides, if exceeded threshold value, judgement has occurred to walk about, for communication unit and satnav unit power up and the collection of enable position information and uploading; Otherwise judgement is wrong report, and power control unit 130 is got back to standby mode.This threshold value can be arranged by server.In addition, when power control unit 130 is during in normal mode of operation, if it is less that motion sensor does not sense the amount of exercise of motion or sensing in long period section, for example, this time period exceedes the threshold value of 10 minutes, motion sensor 140 can send the 3rd control signal to power control unit 130, makes the latter enter standby mode from normal mode of operation.
Motion sensor is for example that model is the gravity sensor of LIS3DSH, adopts the encapsulation of LGA16 microminiature, 16 pins, and power consumption is very low.The chip microcontroller of low-power consumption for power control unit, for example EFM32ZG108F16, adopts the encapsulation of QFN24 microminiature, 24 pins, under park mode, lowest power consumption only has tens nA.Even if motion sensor is worked always, add the intermittently power control unit of standby, the electric power that they consume is also very little, the electric power of battery can maintain tens of days.Adopt above-mentioned electric power control program, utilize the device control communication unit of these extremely low power dissipations and the electric power of satnav unit, can reach the minimum power consumption of whole positioning equipment.
In Fig. 1, also show the low pressure difference linear voltage regulator (LDO) being connected between battery 150 and power control unit 130, motion sensor unit 140; it can reduce load regulation; effectively suppress electromagnetic interference (EMI) (EMI), strengthened the overcurrent protection function of Switching Power Supply.Second switch device 180 also can comprise LDO, and the latter can control its switch by control signal.
Fig. 2 illustrates the operational mode change figure of power control unit 130 according to an illustrative embodiment of the invention.Power control unit, in response to the wake-up signal receiving from motion sensor 140, enters into normal mode of operation S2 from standby mode S1.For fear of wrong report, power control unit 130 first judges after being waken up whether the motion/displacement variable within a period of time has exceeded threshold value, if it is rests on normal mode of operation S2, otherwise gets back to standby mode S1.Under normal mode of operation S2, in response to specified conditions, for example, arrive certain special time period or enter certain locality, enter standby mode S1.
