Fig. 8 to Figure 11 is the general flowchart of the main action of the wrist-watch with GPS 10 that relates to of expression present embodiment etc.
The action of the wrist-watch with GPS 10 that present embodiment is related to according to the process flow diagram of Fig. 8 to Figure 11 etc. describes below, and relatedly with it various programs and the various data of Fig. 5 to Fig. 7 is described.
At first, the wrist-watch with GPS 10 of Fig. 1 for example carries out time adjustment in the specific time to its clockwork 18 termly every day.And this time adjustment is undertaken by the signal that receives gps satellite 15 grades as described later.
Therefore, shown in the ST1 of Fig. 8, at first judge whether Measuring Time into regulation.And, under the situation of Measuring Time that is regulation, enter ST2.Judge in ST2 whether solar cell is more than the generated energy of regulation.And, be the generated energy of regulation when above when in ST2, being judged as solar cell, carry out the outdoor process of measurement of ST3, and when sun power be not the generated energy of regulation when above, the indoor process of measurement of execution ST4.
Promptly, as mentioned above, wrist-watch 10 with GPS is from carrying out time adjustment around the received signals such as gps satellite 15 that run on the earth sky, therefore even be disposed under the indoor situation such as buildings at wrist-watch 10 with GPS, want from being positioned at the received signals such as gps satellite 15 of zenith high altitudes such as (the positive sky of device), also can be owing to blocking of the roof of buildings etc. etc. is difficult to receive.
But because buildingss etc. have window, when the wrist-watch 10 with GPS is disposed at when indoor, if the gps satellite 15 of low clearance (elevation angle little and with respect to zenith near low horizontal line configuration) etc., then the signal of its transmission is not blocked by can on the roof etc. of buildings etc. and enter in the buildings from window etc., and the wrist-watch 10 that therefore has GPS is easy to receive this signal.
Therefore, the wrist-watch 10 with GPS forms following program as described later in the indoor process of measurement of ST4: gps satellite 15 grade and the received signals of catching low clearance.Be elaborated in the back.
On the other hand, when the wrist-watch 10 with GPS is disposed at when outdoor, then need to consider the existence of its nearby buildings etc.Therefore as can be known, if from the received signals such as gps satellite 15 of low clearance, then because blocking of buildings etc. is difficult to reception.So preferred in this case trying one's best from high altitude, as far as possible from being positioned at the received signals such as gps satellite 15 in zenith (the positive sky of device).
Therefore, the wrist-watch 10 with GPS forms following program as described later in the outdoor process of measurement of ST3: gps satellite 15 grade and the received signals of catching high altitude.Be elaborated in the back.
Like this, in the present embodiment, be positioned at indoor or outdoor situation according to wrist-watch 10 and change thereafter program with GPS.But,, therefore need judge according to the generated energy of the solar cell of T2 because can't to judge directly that the wrist-watch 10 with GPS is in outdoor or indoor.
That is, be disposed at outdoorly if having the wrist-watch 10 of GPS, then generated energy increases, and on the contrary, if be disposed at indoorly, then generated energy reduces, thereby is the judgement that benchmark carries out indoor and outdoor with this generated energy.
Be elaborated below.Figure 12 is that the expression solar cell is the curve map that concerns between generated energy and the illumination relatively in the solar panel formula charging device 21 of Fig. 3.Illumination in this curve map is indoor low and at outdoor height.
In addition, generated energy and this illumination change accordingly relatively.As shown in Figure 12, when relative generated energy during less than 0.5 (5000lx), it is higher to be in indoor probability, and under the situation more than 0.5, it is higher then to be in outdoor probability.
Therefore, in the present embodiment, for example relatively generated energy is 0.5 (lx) when above, be judged as the wrist-watch 10 with GPS be disposed at outdoor, and when relative generated energy during less than 0.5 (lx), be judged as be disposed at indoor.
And in advance such data are judged that as this indoor/outdoor being stored in indoor/outdoor with generated energy data 41a judges with in the generated energy data store 41.
That is, in ST2, at first the generated energy of the wrist-watch with GPS 10 of execution graph 5 is obtained program 31, obtains the generated energy data of solar panel formula charging device 21, and is stored in the generated energy data store 51 as the generated energy data 51a of Fig. 7.
Then, the indoor/outdoor determining program 32 of execution graph 5, and the indoor/outdoor of the generated energy data 51a of Fig. 7 and Fig. 6 judged compare with generated energy data 41a.Particularly, judge that generated energy data 51a is whether relative generated energy is more than 0.5 (lx) shown in Figure 12.
And, when generated energy data 51a is 0.5 (lx) when above, is judged as wrist-watch 10 and is in outdoorly with GPS, carry out the outdoor process of measurement of ST3, and when the time less than 0.5 (lx), be judged as the wrist-watch with GPS be in indoor, the indoor process of measurement of execution ST4.
Therefore, in the present embodiment, it is outdoor or outdoor to judge accurately that the wrist-watch 10 with GPS is in.
Like this, to obtain program 31 be to obtain an example of the environmental information obtaining section of the environmental information of acceptance division (GPS device 19) (generated energy data 51a) to generated energy.Indoor/outdoor determining program 32 then is based on the example of reception environment information generating unit that environmental information (generated energy data 51a) generates the reception environment information (indoor and outdoor) of acceptance division (GPS device 19).In addition, generated energy data 51a is that acceptance division (GPS device 19) is disposed at indoor indoor configuration information or is disposed at an example of outdoor outdoor configuration information.ST2 then is the example that environmental information obtains step and reception environment information generation step.
Based on Fig. 9 the outdoor process of measurement of the ST3 of Fig. 8 is described below.Fig. 9 is the general flowchart of the outdoor process of measurement of presentation graphs 8.
At first, shown in ST31, select the gps satellite of high altitude based on calendar data.That is, preferred as mentioned above from the received signals such as gps satellite 15 of high altitude in outdoor process of measurement, and judge the height of gps satellite 15 grades in the present embodiment according to calendar data.
Calendar data is the summary orbital data of earth-circling all gps satellite 15 grades.Therefore, for example Japanese in certain place, being informed in sometime with reference to this calendar data, certain gps satellite 15 grade is positioned at certain height (elevation angle).
Such calendar data is the calendar data 42a of Fig. 6, and calendar data 42a is stored in the calendar data storage part 42.
That is, the high altitude satellite option program 33 of Fig. 5 is based on the calendar data 42a of Fig. 6, for example selects the gps satellite 15 etc. of one high altitude in the location of the wrist-watch 10 with GPS (for example Japan).
Like this, in the present embodiment, count the gps satellite 15 etc. of selecting high altitude according to 42a within the next few days one by one, therefore can select the gps satellite 15 of high altitude etc. accurately according to the precise information relevant with the height of gps satellite 15 grades.
High altitude satellite option program 33 is based on the example that reception environment information (wrist-watch 10 with GPS is in indoor or outdoor information) is come the positional information satellite selection portion of the positional information satellite (gps satellite 15 etc.) that selective reception portion (GPS device 19) will receive.And calendar data 42a is that the earth-circling summary orbit information of a plurality of positional information satellites (gps satellite 15 etc.) is an example of whole satellite summary orbit informations.
In addition, high altitude satellite option program 33 also be based on reception environment information (wrist-watch 10 with GPS is in indoor or outdoor information) and all satellite summary orbit information (calendar data 42a) come an example of the structure of the positional information satellite (gps satellite 15) that selective reception portion (GPS device 19) will receive.
And, high altitude satellite option program 33 also be when environmental information (generated energy data 51a) when the outdoor configuration information, select the example of structure of the positional information satellite (gps satellite 15 etc.) of high altitude according to whole satellite summary orbit informations (calendar data 42a).And ST31 is the example that the positional information satellite is selected step.
Then, enter the ST32 of Fig. 9, a gps satellite 15 grades of selecting in ST31 are scanned.That is, the calendar data 42a according to the gps satellite of selecting among the ST31 15 searches for this gps satellite 15.
Then, in ST33, judge whether successfully to catch gps satellite 15, when not successful, enter ST34.
In ST34, judge in ST31 by high altitude satellite option program 33 selected gps satellite 15 grades whether be a plurality of.Then, if selected other gps satellite 15 etc.,, in ST32, scan gps satellite 15 etc. once more then based on the calendar data 42a of these gps satellite 15 grades.
On the other hand, when in ST33, successfully catching gps satellite 15 grades, enter ST36, receive the signal of gps satellite 15 grades.Before this step of explanation, the satellite-signal to gps satellite 15 grades describes earlier.
Figure 13 is the diagrammatic illustration figure of the satellite-signal of expression gps satellite 15 grades.
Shown in Figure 13 (a), be that unit sends signal from gps satellite 15 grades with a frame (30 seconds).This frame has five subframes (subframe is 6 seconds).Each subframe has ten words (word is 0.6 second).
In addition, the lead-in of each subframe is the TLM word that stores TLM (Telemetry word) data, shown in Figure 13 (b), stores preamble (preamble) data in the stem of this TLM word.
In addition, the word after the TLM is the HOW word that stores HOW (handover word) data, and its stem stores the GPS time information of the gps satellite that is called TOW (Time of week).
GPS constantly shows from 0 o'clock on every Sundays elapsed time with stopwatch, and make zero in 0 o'clock of Sunday in next week.And, therefore can obtain GPS constantly at receiver side by the data that obtain all sequence numbers and elapsed time (second) to giving all sequence numbers of GPS this week.This GPS starting point constantly is UTC (Universal Time Coordinated: Universal Time Coordinated).
And, for the frame data of obtaining such gps satellite 15 grades etc., and need make the signal Synchronization of receiver side and gps satellite 15 etc., use C/A sign indicating number (1023 chips (1ms)) synchronously for what realize 1ms unit especially.
Owing to send signal from gps satellite 15 grades as mentioned above, therefore in the present embodiment, shown in the ST36 of Fig. 9, phase place that makes receiver side and phase-locking from the C/A sign indicating number of gps satellite 15 grades, and it is shown in Figure 13 (b), synchronous with the TOW of the preamble of TLM word and HOW word.
Particularly, a satellite seizure/synchronization program 34 of execution graph 5 makes the TOW of the preamble of receiver side and TLM word and HOW word synchronous.
Then enter ST37.In ST37, obtain GPS constantly from the TOW that receives.
Promptly, in the present embodiment, do not obtain the data, for example year calendar (detailed orbit information separately such as each gps satellite 15a), calendar (the summary orbit informations of all gps satellite 15a etc.), UTC data (Universal Time Coordinated) of each frame shown in Figure 13 (a) etc., and only obtain the GPS data constantly that are called TOW.
Particularly, the GPS of Fig. 5 obtains program 35 constantly and obtains above-mentioned GPS data constantly, as the GPS of Fig. 7 constantly data 52a be stored in GPS data store 52 constantly.
Therefore, in the present embodiment, can shorten the time of the GPS device 19 of wrist-watch 10 very significantly, thereby further reduce power consumption from received signals such as gps satellites 15 with GPS.
Like this, acceptance division (GPS device 19) is obtained satellite time information (GPS constantly) from positional information satellite (gps satellite 15 etc.).ST36 is the example of receiving step of the acceptance division receiving satellite signal of electronic equipment.
In addition, in ST37, with the data addition of this gps data 52a that obtains and corresponding average transfer delay time highly as revising constantly.
Here, to highly the corresponding average transfer delay time describes.In the present embodiment, because do not obtain the almanac data of gps satellite 15 grades, so can't calculate the distance between gps satellite 15 grades and the GPS device 19 (wrist-watch 10), therefore can't calculate the propagation delay time that arrives GPS device 19 from the signal of transmission such as gps satellite 15 grades with GPS.
Therefore, in the present embodiment, store the data in this propagation delay time corresponding in advance with difference in height.That is, in the position of gps satellite 15 grades near under the horizontal situation, with zenith (directly over) situation compare, the propagation delay time of signal becomes big.Therefore, average out corresponding to propagation delay time height change, signal of such gps satellite 15 grades, and, be stored in highly corresponding average transfer delay time data storage part 43 as the corresponding average transfer delay time data of the height 43a of Fig. 6.
Therefore, modification shown in Figure 5 constantly operation program 36 obtain the GPS that in ST37, receives constantly data 52a and with the corresponding corresponding average transfer delay time data of the height 43a of elevation information (42a obtains from calendar data) of this gps satellite 15 etc., and, revise data constantly thereby can generate with highly corresponding average transfer delay time data 43a and GPS data 52a addition constantly.
The modification that generates like this is data constantly, as the modification of Fig. 7 constantly data 53a be stored in and revise data store 53 constantly.
That is, these modification moment data become the consistent high time information of precision of atom clock and watch that is carried with gps satellite 15 grades.
It is the example that the propagation delay time information satellite related with the elevation information of positional information satellite (gps satellite 15 etc.) constitutes related propagation delay time information that like this, highly corresponding average transfer delay time data 43a becomes from the temporal information of the satellite-signal arrival acceptance division (GPS device 19) of positional information satellite (gps satellite 15 etc.) transmission.In addition, revising constantly, operation program 36 is based on the example that satellite time information (GPS is data 52a constantly) related propagation delay time information with satellite altitude (highly corresponding average transfer delay time data 43a) generates the time adjustment information generating unit of time adjustment information (revising data 53a constantly).In addition, the modification of Fig. 7 constantly data 53a be an example that is used to revise the time adjustment information of time information.And ST37 is the example that time adjustment information generates step.
Then, enter ST38.In ST38, the clockwork compensation program 37 of Fig. 5 is based on the modification moment data 53a of Fig. 7, the moment of revising clockwork 18.
Therefore, in outdoor process of measurement, can promptly catch the gps satellite 15 of high altitude etc., and only be called the signal of TOW and can carry out high-precision time adjustment by reception.Can carry out the good wrist-watch with GPS 10 that high-precision time adjustment and power consumption reduce simultaneously thereby become.
The outdoor process of measurement of ST3 of Fig. 8 more than is through with.
In addition,, be not limited thereto, can and realize that also the subframe of synchronous gps satellite 15 etc. obtains almanac data from seizure though in this enforcement, in ST36, do not obtain almanac data.At this moment, have the location aware of the wrist-watch 10 of GPS, calculate satellite distance and propagation delay time, and compare, thereby can obtain the moment of revising data constantly and revising clockwork 18 with propagation delay time of clockwork 18 actual measurements.
Below, the indoor process of measurement of the ST4 of Fig. 8 is described.Figure 10 and Figure 11 are the general flowcharts of the indoor process of measurement of Fig. 8.
At first, shown in the ST41 of Figure 10, judge whether to exist the bearing data that receives gps satellite 15 grades in the past.
That is, if according to the bearing search gps satellite 15 identical with successfully catching in the past successful gps satellite 15 etc. etc., then can more promptly catch gps satellite 15 etc.And can avoid carrying out invalid reception action and can reduce power consumption.
Particularly, the bearing data that receives gps satellite 15 grades in the past receives bearing data 44a and is stored in satellite take over party parallactic angle data store 44 as the satellite of Fig. 6.
In addition, the corresponding satellite in the position angle of Fig. 5 determines that program 38 receives bearing data 44a with reference to the satellite of Fig. 6 and judges.
When existing satellite to receive bearing data 44a, enter ST42, with reference to these data.
Like this, to receive bearing data 44a be the example that the azimuth information of the positional information satellite (gps satellite 15 etc.) that receives in the past of acceptance division (GPS device 19) promptly receives azimuth information to satellite.
On the other hand, when in ST41, not receiving the bearing data of gps satellite 15 grades in the past, enter ST43, with reference to the preferential bearing data of selecting.
Should preferential select bearing data is the data of importing in advance as the position angle that is easy to catch gps satellite 15 grades.Therefore, based on this preferential bearing data of selecting gps satellite 15 grades are searched for, thereby can catch gps satellite 15 etc. rapidly, power consumption is reduced.
The preferential selection bearing data 45a that should preferentially select bearing data as Fig. 6 is stored in preferential selection bearing data storage part 45.
And particularly, the corresponding satellite in the position angle by Fig. 5 determines that program 38 carries out reference.
Like this, preferentially selecting satellite position angular data 45a is that the azimuth information of positional information satellite (gps satellite 15 etc.) is an example of particular orientation information.
Then, enter the ST44 of Figure 10.In ST44, low-altitude satellite option program 39, based on the bearing data of gained among ST42 or the ST43, with reference to the calendar data of Fig. 6, judge in this position (for example Japan) special time, whether have gps satellite 15 etc. at the position angle of regulation.And low-altitude satellite option program 39 is stored in the corresponding satellite data storage part 54 in position angle with corresponding gps satellite 15 grades as the corresponding satellite data 54a in the position angle of Fig. 7.
And in ST45, low-altitude satellite option program 39 is selected the gps satellite 15 of a low clearance (the little elevation angle for example 45 degree is following) etc. according to the corresponding satellite data 54a in position angle.
Therefore, being in that the indoor wrist-watch with GPS 10 can select rapidly can be from gps satellite 15 of the received signals such as window of this buildings etc. etc.Therefore, can carry out the reception action rapidly and power consumption is reduced.
Like this, low-altitude satellite option program 39 is examples of the positional information satellite selection portion of the positional information satellite (gps satellite 15 etc.) that the whole satellite summary orbit informations (calendar data 42a) of basis are selected low clearances when environmental information (generated energy data 51a) is indoor information.
In addition, low-altitude satellite option program 39 is preferential examples selecting the positional information satellite selection portion of the positional information satellite (gps satellite 15 etc.) that meets with receive direction information (satellite receives bearing data 44a) when selecting the positional information satellite (gps satellite 15 etc.) of low clearances according to whole satellite summary orbit informations (calendar data 42a).In addition, low-altitude satellite option program 39 is preferential examples selecting the positional information satellite selection portion of the positional information satellite (gps satellite 15 etc.) that meets with particular orientation information (preferentially selecting satellite position angular data 45a) when selecting the positional information satellite (gps satellite 15 etc.) of low clearances according to whole satellite summary orbit informations (calendar data 42a).
On the other hand, when the gps satellite that do not have on this position angle in ST44 to catch, enter ST46, low-altitude satellite option program 39 is with reference to calendar data 42a, and obtains the time data of gps satellite 15 grades that appearance can be caught on this position angle.
And wait for that in ST47 till this time of occurrence, low-altitude satellite option program 39 is selected the gps satellite 15 of a low clearance etc. in ST45.
Therefore, in the time on specific position angle, can receiving gps satellite 15 grades, even before can receiving under the time-consuming more situation, also can prevent GPS device 19 from carrying out invalid search continuously and only drive GPS device 19, therefore can not cause that ineffective power consumption ground receives in time of necessity.
Like this, calendar data 42a is that the seasonal effect in time series mobile message with positional information satellite (gps satellite 15 etc.) is an example of satellite time mobile message.And low-altitude satellite option program 39 becomes based on the satellite time mobile message of a calendar data 42a and additional wait time example with the structure of chosen position information satellite (gps satellite 15 etc.).
In ST45, when low-altitude satellite option program 39 is selected gps satellite 15 grades of low clearance, enter ST48, a satellite seizure/synchronization program 34 of execution graph 5 is caught this gps satellite of selecting 15 etc.
If can the seizure of these gps satellite of selecting 15 grades failure then judge the gps satellite 15 that select other low clearance etc. in ST49, if can, the gps satellite 15 of low clearance etc. then in ST50, selected.
The ST51 that enters Figure 11 below is to ST53.The ST36 of these steps and the outdoor process of measurement of Fig. 9 is identical and omit explanation to ST38.In addition, in these steps, also obtain almanac data as mentioned above, instrumented satellite distance and propagation delay time, and compare with propagation delay time of clockwork actual measurement, as the time adjustment data.
As mentioned above, according to present embodiment, wrist-watch 10 with GPS judges that its reception environment is indoor or outdoor, select suitable gps satellite 15 etc. based on its judged result and according to calendar data 42a etc., and it is caught and received signal, thereby can carry out high-precision time adjustment with lower power consumption.Especially for the electronic equipment that clock and watch require super low-power consumption and high precision time adjustment like that, present embodiment is the most effective.

In addition, in first storage part 140 of Figure 17, mainly gather and represented the data of accommodating in advance.In addition, in second storage part 150, mainly show data of obtaining in data after data in first storage part 140 etc. being handled and the routine processes process etc. by the various programs of indoor and outdoor determining program storage part 60.
Figure 18 is the skeleton diagram of the data in first storage part 140 of expression Figure 17, and Figure 19 is the skeleton diagram of the data in second storage part 150 of expression Figure 17.And Figure 20 is the skeleton diagram of program of the indoor and outdoor determining program storage part 60 of expression Figure 17.
Figure 21 to Figure 24 is the general flowchart of the main action of the wrist-watch with GPS 100 that relates to of expression present embodiment etc.
Below the action etc. of the wrist-watch with GPS 100 that present embodiment related to according to the process flow diagram of Figure 21 to Figure 24 describe, and various programs and the various data of Figure 17 to Figure 20 are described relatedly with it.
At first, the wrist-watch with GPS 100 of Figure 14 is carrying out the time adjustment of its clockwork 18 sometime.And this time adjustment is undertaken by the signal that receives gps satellite 15a etc. as described later.
Therefore, as the last stage of the signal that receives gps satellite 15a etc., judge that whether the wrist-watch 100 with GPS is the state that can receive the signal of gps satellite 15a etc., promptly judges that the wrist-watch 100 with GPS is in indoor or outdoor.Therefore as, shown in the ST11 of Figure 21, select in the various programs of indoor and outdoor determining program storage part 60 any or a plurality of the execution.Below, under in the various programs of expression indoor and outdoor determining program storage part 60 any or a plurality of situations, describe as indoor and outdoor determining program 601, and in explanation wherein under the situation of each program, the program of selecting as indoor and outdoor determining program 601 is shown and describes.
Then, then enter ST12, judge whether normal termination of indoor and outdoor determining program 601.And, under the situation of normal termination, be judged as and can receive the outdoor of gps satellite 15a etc., enter ST15, for example catch gps satellite 15a more than four etc.Particularly, make GPS device 19 actions of Figure 16, receive gps signal, the gps satellite 15a that search can be caught etc. from antenna 11.Then enter ST16, carry out the time emendation program 136 of Figure 17, enter ST17 then, particularly, carry out time adjustment in the step below.
Here, the satellite-signal identical (Figure 13) of the satellite-signal of gps satellite 15a etc. and the gps satellite 15 described in first embodiment.
Therefore, in the present embodiment, shown in the ST17 of Figure 21, make receiver side synchronous with C/A sign indicating number from gps satellite 15a etc., and synchronous with the TOW of the preamble of TLM word and HOW word.Then, the wrist-watch 100 with GPS is obtained the navigation data of four gps satellite 15a etc.
Then, enter ST18, use clockwork 18 to measure propagation delay time (arriving the time of wrist-watch 100 from the signal of gps satellite) with GPS from the signal of this four gps satellite 15a etc., and based on the light velocity (c) data computation gps satellite 15a etc. and have virtual satellite distance between the wrist-watch 100 of GPS.Then, based on virtual satellite distance from four gps satellite 15a etc., by four simultaneous equationss calculate the position of wrist-watch 100 with GPS, highly, the genuine propagation delay time, and position, positional information, the genuine propagation delay time of calculating wrist-watch 100 with GPS.
Like this, can obtain genuine propagation delay time and by propagation delay time of clockwork 18 actual measurements.
Like this, with actual measurement receive from the propagation delay time of time of the signal of four transmissions such as gps satellite 15a be benchmark.And, generate the positional information of the wrist-watch of obtaining by calculating with GPS 100, genuine propagation delay time and conduct propagation delay time by the measured value of clockwork 18 measurements.
Then, in ST19, the difference between the propagation delay time that goes out based on the inner clock and watch actual measurement of the use of genuine propagation delay time of obtaining by calculating and clockwork 18 compensates (modification) clockwork 18.
Then, shown in ST20, moment of the moment display part 28 on the dial plate 12 of Figure 14 shows based on the data with the clockwork 18 of UTC N Reference Alignment that obtain from gps satellite 15a etc. makes amendment, and the moment of display part 28 shows that becoming time information revises display part constantly.
Therefore, for example show the Japan time of having considered the time difference.
More than, be through with and use the time adjustment of four satellites.This is because according to the time information of the gps satellite 15a etc. with atom clock and watch, can make amendment to the clockwork 18 of wrist-watch 100 with GPS, thus the moment that can revise wrist-watch 100 accurately with GPS.
In addition,, enter ST13, force to finish indoor and outdoor determining program 601, will be shown in display 14 as the meaning of the environment that can't catch gps satellite to notify the user when in ST12, being judged to be when not having normal termination.User Recognition shows and shows in ST14 and judge the meaning of revising the moment with manual operation according to the user, and finishes a series of actions.
More than, the time adjustment among the Figure 21 that is through with.
Therefore, in this embodiment, serve as main time adjustment to be illustrated with the situation of a plurality of satellites more than four, but be not limited thereto, also can be to use the time adjustment of a satellite.
In this case, known self-position promptly has the position of the wrist-watch 100 of GPS.Wrist-watch 100 with GPS catch satellites and make the C/A sign indicating number synchronously, make preamble and TOW synchronously obtain almanac information.And can obtain the positional information on the track of this gps satellite 15a that captures etc. according to obtained almanac information.Then, use known self-position to calculate to find the solution genuine propagation delay time (virtual satellite distance) from the signal of gps satellite 15a etc.
Then, use clockwork to obtain the propagation delay time of reality from the signal of gps satellite 15a reception.Therefore, can obtain actual propagation delay time and genuine propagation delay time.ST18 and the ST19 of the step of back Figure 21 during with above-mentioned four satellites are identical.Then, finish a satellite time adjustment pattern.
In a satellite time adjustment pattern, can catch a gps satellite 15a and receive data.Therefore, compare, can significantly reduce power consumption with the situation of catching four gps satellite 15a etc.Like this, also can be used in combination the time adjustment of four satellites and the time adjustment of a satellite, thereby can keep time adjustment accurately, and reduce power consumption.
Below individual other indoor and outdoor determining program 601 is described.
In the ST10 of Figure 21, carry out indoor and outdoor determining program 601.Here, as this indoor and outdoor determining program 601, comprising: the generated energy trace routine 61 of Figure 20 that the solar panel formula charging device 21 of Figure 16 and Figure 17 relates to and the situation of general flowchart of representing Figure 22 of its action; The acceleration transducer output waveform trace routine 63 of Figure 20 that the acceleration transducer output unit waveform generating apparatus 29 of Figure 16 and Figure 17 relates to and the situation of general flowchart of representing Figure 23 of its action; Show extraction procedure 62, generated energy/acceleration option program 64 sunshine that further relates to Figure 20 according to above-mentioned generated energy trace routine 61 and acceleration transducer output waveform trace routine 63 and represent the situation of general flowchart of Figure 24 of its action.
Judge that this on the one hand the wrist-watch 100 with GPS being in indoor or outdoor situation, although for example having the wrist-watch 100 of GPS is in indoor, in order to carry out time adjustment, begin to receive action from around the received signals such as gps satellite 15a in the earth sky time.This reception action is set at usually to be carried out several times, even therefore taking defeat of acceptance division can directly not stop to receive action yet.Therefore, in this process, continue consumed power.In this case, owing to battery 20 capacity of the mini-plant that is equipped on the wrist-watch 100 with GPS are generally less, thereby cause battery to be used up and the problem of time under reach.
Therefore, when being judged as the wrist-watch 100 with GPS by this indoor and outdoor determining program 601 when being in indoor environment, acceptance division does not receive action, and only begins to receive action when outdoor being judged as.Like this, can carry out reception effectively and move and avoid invalid power consumption, therefore make battery prolongation service time.Therefore, even in the mini-plant that battery capacity is existed restriction, also can carry the GPS device.
Below individual other indoor and outdoor determining program 601 is described.
(about generated energy trace routine 61)
As indoor and outdoor determining program 601, the situation of the generated energy trace routine 61 of selecting Figure 20 is described.
Generated energy trace routine 61 relates to the solar panel formula charging device 21 of Figure 16 and Figure 17, and its action is illustrated in the general flowchart of Figure 22.
When carrying out the indoor and outdoor determining program 601 of ST11 of Figure 21, select the generated energy trace routine 61 of Figure 20.Then, in the ST100 of Figure 22, carry out generated energy trace routine 61, judge that according to the generated energy of solar cell the wrist-watch 100 with GPS is in indoor or outdoor.
That is, be disposed at outdoorly if having the wrist-watch 100 of GPS, then generated energy increases, and on the contrary, if be disposed at indoorly, then generated energy reduces, and is the judgement that benchmark carries out indoor and outdoor with this generated energy therefore.
Therefore, as using in the first embodiment Figure 12 illustrates, in the present embodiment, as the generated energy threshold data 143a that is contained in generated energy threshold data resettlement section 143 shown in Figure 180, for example be redefined for 0.5 (lx), and when detected generated energy in solar panel formula charging device 21 be 0.5 (lx) when above, the environment that is judged as the wrist-watch 100 with GPS is outdoor, and when less than 0.5 (lx), the environment that is judged as the wrist-watch 100 with GPS is indoor.
That is, in ST100, carry out generated energy trace routine 61.Then, enter ST101, generated energy trace routine 61 detects the generated energy of solar panel charging device 21, and the generated energy that is stored in Figure 19 detects data store 152.Then, enter ST102, the generated energy threshold data 143a that the generated energy of the generated energy detection data store 152 of 61 couples of Figure 19 of generated energy trace routine detects the generated energy threshold data resettlement section 143 of data 152a and Figure 18 compares.Particularly, generated energy trace routine 61 judges that it is whether relative generated energy is more than 0.5 (lx) shown in Figure 12 that the generated energy of Figure 19 detects data 152a.Then, entering ST103, is that generated energy threshold data 143a (0.5 (lx)) is when above when generated energy detects data 152a, enter ST105, be judged as the state that to catch gps satellite, promptly be judged as wrist-watch 100 and be in outdoorly, finish generated energy trace routine 61 with GPS.Then, return the ST12 of above-mentioned Figure 21, generated energy trace routine 61 normal terminations of selecting as indoor and outdoor determining program 601 and enter ST15, the scanning of beginning gps satellite is also caught gps satellite more than four.Then, measure self-position and carry out time adjustment by the action of ST16~ST20 like that as mentioned above.
But, in ST103, when generated energy detects data 152a less than generated energy threshold data 143a (0.5 (lx)), enter ST104, for example repeat about N=5 time the action from ST101 to ST103.Then, be more than 5 times the time when generated energy detects data 152a less than the number of times of generated energy threshold data 143a (0.5 (lx)), force to finish this generated energy trace routine 61.Then, return the ST12 of Figure 21.Then, if there is not the normal termination program, then enter ST13, the user is shown as the meaning that can't catch the situation of gps satellite, as mentioned above, in ST14, show and judge the meaning of revising the moment by manual operation according to the user, and finish a series of actions.
Therefore, in the present embodiment, it is indoor or outdoor to judge accurately that the wrist-watch 100 with GPS is in.
Like this, generated energy trace routine 61 becomes the example that the environmental information that obtains acceptance division (GPS device 19) is the indoor and outdoor judging part of generated energy detection data 152a and the reception environment (indoor or outdoor) of judging acceptance division (GPS device 19) based on these generated energy detection data 152a.
And under the situation that can receive, acceptance division receives action and measures self-position and carry out time adjustment, and in the time can't receiving, acceptance division does not receive action, therefore can suppress power consumption.
In addition, since here can be when carrying out generated energy trace routine 61 generated energy of gained detect data 152a be the threshold value of generated energy threshold data 143a when above period and for the period of the threshold value of generated energy threshold data 143a when following is stored in the indoor and outdoor judgment data storage part 58 of Figure 19 in advance, thereby can determine to want the period of catching position information satellite based on the period of indoor and outdoor judgment data storage part 58.Therefore, always there is no need to detect according to the generated energy of solar panel formula charging device 21, is favourable for the user therefore.
(about acceleration transducer output waveform trace routine 63)
As the indoor and outdoor determining program 601 of Figure 20, the situation of the acceleration transducer output waveform trace routine 63 of having selected Figure 20 is described.Acceleration transducer output waveform trace routine 63 is relevant with the acceleration transducer output waveform generating apparatus 29 of Figure 16 and Figure 17, so its action is illustrated in the general flowchart of Figure 23.
In the ST11 of Figure 21, when carrying out indoor and outdoor determining program 601, select the acceleration transducer output waveform trace routine 63 of Figure 20.Then, carry out the generated energy trace routine of the ST200 of Figure 23.This is because to judge that with the amplitude of the output waveform of acceleration transducer 125 wrist-watch 100 with GPS is in indoor or outdoor.
That is, when the wrist-watch 100 with GPS is disposed at when outdoor, the amplitude of the output waveform of acceleration transducer 125 increases to a certain degree.On the contrary, indoor as if being disposed at, then the amplitude of output waveform reduces.Thus, the amplitude with this output waveform is the judgement that benchmark carries out indoor and outdoor.Perhaps according to amplitude and based on carrying out frequency analysis by the output waveform of acceleration transducer output waveform generating apparatus 29 gained, be benchmark whether to obtain wave period, can carry out the judgement of indoor and outdoor.At this moment, be disposed at outdoorly if having the wrist-watch 100 of GPS, then the result of frequency analysis be for can periodically obtain waveform, on the contrary, if be disposed at indoorly, then can't obtain periodic waveform and be random state.
At Figure 25 to Figure 27 is (a) acceleration transducer output waveform and (b) curve map of frequency analysis data that shows in the acceleration transducer output waveform generating apparatus 29 with acceleration transducer 125.Figure 25, Figure 26 are outdoor situation, and when Figure 25 was outdoor walking, Figure 26 was during for outdoor travelling.The situation of Figure 27 when the indoor activity is when the amplitude of the acceleration transducer output waveform of the amplitude of the acceleration transducer output waveform of Figure 25 and Figure 26 and Figure 27 is compared, bigger under the situation of Figure 25 and Figure 26.In addition, when comparing during to the indoor activity of the outdoor walking of Figure 25 and Figure 27, the amplitude of Figure 25 is about about three times.In addition, when frequency analysis data is compared, under the outdoor situations of Figure 25 and Figure 26, there is periodic waveform, but under the indoor situation of Figure 27, do not have periodic waveform.Therefore, the amplitude of the acceleration transducer output waveform during with the outdoor walking of Figure 25 is a benchmark, will be by the less situation of the output waveform amplitude of acceleration transducer output waveform generating apparatus 29 gained as indoor, and situation that will be bigger is as outdoor.That is in the present embodiment, be benchmark during with the outdoor walking of Figure 25.Then, as the acceleration transducer output waveform amplitude threshold data 441 of acceleration rate threshold data resettlement section 144, the amplitude setting during with the outdoor walking of Figure 25 is for example " 1 ".In addition, when the output waveform amplitude by acceleration transducer output waveform generating apparatus 29 gained is " 1 " when above, the environment that is judged as the wrist-watch 100 with GPS is outdoor, and when less than " 1 ", the environment that is judged as the wrist-watch 100 with GPS is indoor.
That is, in ST200, when carrying out acceleration transducer output waveform trace routine 63, in ST201, obtain acceleration transducer output waveform and/or frequency analysis data from acceleration transducer output waveform generating apparatus 29 with acceleration transducer 125.Acceleration transducer output waveform trace routine 63 obtains the acceleration transducer detection data store 154 that data are contained in Figure 19 with this.Then, acceleration transducer output waveform trace routine 63 detects the acceleration transducer output waveform 154a and/or the frequency analysis data 154b of data store 154 from being contained in acceleration transducer in ST202, obtain amplitude data 57a and or the cycle data 57b of frequency, and be stored in the generation amplitude of wave form data store 57 of Figure 19.
Enter ST203 then, the acceleration transducer output waveform amplitude threshold data 441 of acceleration rate threshold data resettlement section 144 that 63 pairs of acceleration transducer output waveform trace routines are stored in the amplitude data 57a that generates amplitude of wave form data store 57 and Figure 18 are that the amplitude data (for example " 1 ") of benchmark compares during promptly with the outdoor walking of Figure 25.Can then in ST204, acceleration transducer output waveform trace routine 63 judges whether to be acceleration transducer output waveform amplitude threshold data more than 441, and/or obtain the cycle data of frequency.In addition, be that acceleration transducer output waveform amplitude threshold data are more than 441, and/or can obtain to enter ST209 under the situation of cycle data 57b of frequency, measure the output time of acceleration transducer output waveform generating apparatus 29 with acceleration transducer 125.Enter ST211 then, acceleration transducer output waveform trace routine 63 judge output time whether continue the stipulated time above, for example for continuing more than 1 minute, when continuing more than 1 minute, enter ST212, as the state that can catch gps satellite, and finish acceleration transducer output waveform trace routine 63.That is, be judged as the wrist-watch 100 with GPS and be in outdoorly, finish acceleration transducer output waveform trace routine 63, return the ST12 of above-mentioned Figure 21, as normal termination, enter ST15, the gps satellite more than four is caught in the scanning of beginning gps satellite.In addition, measure the self-position and the modification moment by the action of ST16~ST20 as mentioned above.
In addition, in ST211, whether be that judgement more than 1 minute for example repeats N=5 time.Although suppose outdoor, but do not have under the situation of acceleration transducer output situation that for example also may be because user's waiting signal etc. stops to move etc., so repeat to measure about 5 times in the time about less than 1 minute.In addition, when more than N=5 time and output time during less than 1 minute enters ST207, the stop time measurement timer.In addition, in ST208, the time measurement timer is resetted, make as the acceleration transducer output waveform trace routine 63 of indoor and outdoor determining program 601 and force to finish.In addition, return the ST12 of Figure 21,, enter ST13 when program not during normal termination, the user is shown as the meaning that can't catch the situation of gps satellite, and in ST14, show as mentioned above and according to user's judgement and revise the meaning constantly by manual operation and finish.
Then return ST204 once more, but be here less than acceleration transducer output waveform amplitude threshold data 441, and/or can't obtain under the situation of cycle data 57b of frequency, starting time measurement timer in ST205, measure in advance less than acceleration transducer output waveform amplitude threshold data 441, and/or can't obtain time of the cycle data 57b of frequency.In addition, whether at the appointed time in ST206, measure, for example in the time about a week less than acceleration transducer output waveform amplitude threshold data 441, and/or whether continued to obtain time of the cycle data 57b of frequency, when less than acceleration transducer output waveform amplitude threshold data 441, and/or can't obtain frequency cycle data 57b time remaining one week when above, enter ST207, the stop time measurement timer, in ST208, the time measurement timer is resetted and force to finish.In addition, with similarly above-mentioned, return the ST12 of Figure 21, as not normal termination, enter ST13, the user is shown as the meaning that can't catch the situation of gps satellite, and in ST14, show as mentioned above and according to user's judgement and revise the meaning constantly by manual operation and finish.
Therefore, in the present embodiment, it is indoor or outdoor to judge accurately that the wrist-watch 100 with GPS is in.
Like this, acceleration transducer output waveform trace routine 63 becomes cycle data 57b that the environmental information that obtains acceptance division (GPS device 19) is amplitude data 57a and/or frequency and judges the example of indoor and outdoor judging part of the reception environment (indoor and outdoor) of acceptance division (GPS device 19) based on the cycle data 57b of amplitude data 57a and/or frequency.
In addition, in the time of will carrying out acceleration transducer output waveform trace routine 63 here gained, amplitude data 57a be acceleration transducer output waveform amplitude threshold data more than 441 situation and/or obtained period of the cycle data 57b of frequency; With amplitude data 57a be situation and/or the period that can't obtain the cycle data 57b of the frequency indoor and outdoor judgment data storage parts 58 that in advance are stored in Figure 19 of acceleration transducer output waveform amplitude threshold data below 441, based on the indoor and outdoor judgment data storage part of accumulating 58, can determine the period of catching position information satellite then.Therefore, owing to there is no need to detect by acceleration transducer all the time, be favourable for the user.
As mentioned above, according to present embodiment, clock and watch 100 with GPS judge that its reception environment is indoor or outdoor, and select suitable gps satellite 15a etc. based on this judged result and according to calendar information etc., and catch with received signal, measure self-position and also carry out time adjustment, therefore can carry out high-precision time adjustment and power consumption is reduced.Especially for the electronic equipment that clock and watch require super low-power consumption and high precision time adjustment like this, present embodiment is the most effective.
(about showing extraction procedure 62 and generated energy/acceleration option program 64 sunshine)
As the indoor and outdoor determining program 601 of Figure 20, the further situation of showing extraction procedure 62 and generated energy/acceleration option program 64 sunshine of Figure 20 of having selected is described.
Show that extraction procedure 62 and generated energy/acceleration option program 64 as mentioned above sunshine, select according in the program of execution corresponding generated energy trace routine 61 and acceleration transducer output waveform trace routine 63 which, make generated energy trace routine 61 and 63 complementations of acceleration transducer output waveform trace routine with the relation of sunshine-duration.Its action is illustrated in the general flowchart of Figure 24.
Therefore here, the action of each program of generated energy trace routine 61 and acceleration transducer output waveform trace routine 63 is omitted repeat specification and difference is elaborated as mentioned above.
When in the ST11 of Figure 21, carrying out indoor and outdoor determining program 601, change the ST300 of Figure 24 over to.In ST300, indoor and outdoor determining program 601 judges whether to have preestablished the data at sunshine by the user.Having preestablished under the sunshine-duration data conditions, change ST304 over to, indoor and outdoor determining program 601 should the sunshine-duration data storage in the sunshine-duration of Figure 19 data store 153.Then change ST305 over to, will narrate in the back this, explanation does not preestablish the data conditions at sunshine earlier here.Change ST301 this moment over to, show extraction procedure 62 sunshine of execution Figure 20.Then, change ST302 over to, show the date display part 122 date of acquisition data of Figure 17 that extraction procedure 62 had from the clockwork 18 of Figure 16 sunshine, and be accommodated in the date data storage part 151 of Figure 19.Change ST303 then over to, show extraction procedure 62 sunshine and use the use zone data 56a of the use zone data storage part 56 that is stored in Figure 19 and the date data 151a of date data storage part 151, to be contained in Figure 18 sunshine tables of data resettlement section 141 zone data table 411 and each data between the date data table 413 compare, select corresponding part.This, tables of data resettlement section 141 contained each tables of data of zone data table 411, date data table 413, sunshine-duration tables of data 412 relatedly in matrix at sunshine, if determined the data of two tables of data in each tables of data, then can extract the data of remaining tables of data.
Therefore, here will from clockwork 18 period display part 122 gained date data 151a and use these two data of zone data 56a as given data, can determine the data of the appropriate section of each tables of data, thereby can extract remaining sunshine-duration data from sunshine-duration tables of data 412.In this sunshine-duration tables of data 412, contain each zone data, date data and the sunrise/sunset time corresponding with it.
Here, be stored in and use the use zone data 56a of zone data storage part 56 also can preestablish, and also can store in advance and use the region based on the result who from the gps satellite received signal time, measured self-position in the past by the user.
Then change ST304 over to, the sunshine-duration data of being extracted are accommodated in the sunshine-duration data store 153 of Figure 19.Change ST305 then over to, carry out generated energy/acceleration option program 64 of Figure 20.Here, generated energy/acceleration option program 64 is to select carry out which program in generated energy trace routine 61 and the acceleration transducer output waveform trace routine 63 according to certain condition, and can suitably judge according to the situation of the wrist-watch 100 with GPS.
Promptly, the wrist-watch that has a GPS in judgement is in when indoor or outdoor, generated energy trace routine 61 is owing to the reason as the generated energy of the solar panel formula charging device 21 of solar cell, under situations such as night, sometimes be not suitable for when carrying out the indoor and outdoor judgement, mainly using, therefore need suitably select these indoor and outdoor determining programs 601.
Therefore, in ST305, carry out generated energy/acceleration option program 64.In addition in ST306, generated energy/64 pairs of acceleration option programs are contained in the sunshine-duration data 153a of sunshine-duration data store 153 and compare from the moment data 59a of moment display part 28 gained of the clockwork 18 of wrist-watch 100 with GPS.In addition,, change ST307 over to, enter the execution of generated energy trace routine 61 when the environment of the wrist-watch 100 with GPS is in the sunshine-duration when (daytime).Outside the sunshine-duration, when (night), change ST308 over to, enter the execution of acceleration transducer output waveform trace routine 63.The execution of the execution of these generated energy trace routines 61 and acceleration transducer output waveform trace routine 63 is same as described above and omit explanation.Here, this moment data 59a is the data rewrite that will obtain from moment display part 28 all the time in the moment of Figure 19 data store 59 and the content of accommodating, after this this correction situation of reflection under the situation of implementing time correction.
In addition, under the situation of above-mentioned generated energy trace routine 61 and 63 normal terminations of acceleration transducer output waveform trace routine, change the ST15 of Figure 21 over to.In addition, under the situation of improper end, force to finish these programs in ST13, demonstration, is made as the user and judges to notify the user as the meaning of the situation that can't catch gps satellite in ST14 on display 14.
Like this, can be suitably and successfully select to carry out generated energy trace routine 61 and acceleration transducer output waveform trace routine 63, thus although avoid being in the situation that also begins to receive action in the environment that acceptance division (GPS device 19) can not receive and increase power consumption.
In addition, according to the judgment standard of above-mentioned generated energy/acceleration option program 64, be time data and the indoor and outdoor judgment standard of generated energy trace routine 61 or acceleration transducer output waveform trace routine 63 at sunshine, to start as outdoor situations the period of acceptance division (GPS device 19), and be stored in indoor and outdoor in advance and judge information storage part 58.In addition, also can judge the data of information storage part 58 based on this indoor and outdoor next time, judge whether in the sunshine-duration, be indoor or outdoor, make acceptance division (GPS device 19) begin to receive action.Like this, the judgment standard of indoor and outdoor is known, thereby is easy to select to carry out generated energy trace routine 61 or acceleration transducer output waveform trace routine 63, and the time that shortening will receive is also further reduced power consumption.
In addition,, be not limited thereto though the generated energy of above-mentioned generated energy trace routine 61 and generated energy/acceleration option program 64 is relevant with solar panel formula charging device 21, for example also can the serviceability temperature sensor.Particularly, for example according to generating electricity by the detected temperature difference of temperature sensor.
Though do not illustrate, also can constitute upper surface side mounting temperature sensor, utilize the generated energy that detects the temperature difference between these and generate electricity at a side, for example glass 16 or the watchcase 132 of side of the contact wrist of the bonnet 131 of wrist-watch 100 etc. and contact extraneous air with GPS.
Particularly, this generating for example adopts tabular semiconductor element, is Peltier element (Peltierdevice), the Peltier effect (Peltier effect) that the heat that its utilization produces the junction surface of electric current by two kinds of metals moves to another kind of metal from a kind of metal.In addition, a side that the two ends that constitute two kinds of metals of this Peltier element is arranged at contact wrist etc. respectively and a side that contacts with extraneous air etc., thereby detected temperatures.
In addition, aforesaid way is for according to detected temperature difference circulating current.Detect its generated energy and carry out the judgement of indoor and outdoor.
Under the situation of such serviceability temperature sensor, can carry out indoor or outdoor judgement double tides, though and a thermopair is about 0.4mV, but if use the sensor of a plurality of thermopairs, even small temperature difference, temperature difference more than 3 degrees centigrade are for example then arranged, also can generate electricity, improve accuracy of detection.
The invention is not restricted to above-mentioned embodiment.
