Such as, second position information obtainment unit 302 detects from multiple peripheral public wireless base stations The reception level of the signal of (Wi-Fi access point or NodeB), and based on the difference with transmission level Different detection propagation loss.The base station as transmission sources can be calculated based on carrier frequency and propagation loss Distance, thus the distance away from each public wireless base station and each public wireless base station can be used The positional information of positional information calculation second position information obtainment unit 302.It addition, synchronizing system In the case of system, can estimate by obtaining the relative delay information of signal from each public wireless base station Positional information.

But, the disclosure is not limited to primary importance information obtainment unit 301 and second position information acquisition The particular location of unit 302 obtains function.For primary importance information obtainment unit 301, permissible Obtain the region of position and accuracy aspect that position obtains and second position information obtainment unit 302 be not both important.Primary importance information obtainment unit 301 can obtain the position of high accuracy Information, but positional information cannot be obtained in the region of such as indoor place or basement and (cannot connect Receive gps signal), and power consumption is high.Comparatively speaking, second position information obtainment unit 302 can Substantially to obtain positional information in all regions, but the accuracy of positional information is not higher than first Positional information obtains unit 301.

Monitoring period control unit 303 controls the monitoring period of primary importance information obtainment unit 301, That is, primary importance information obtainment unit 301 obtains the frequency of positional information.If shortening monitoring period, That is, increase the acquisition frequency of positional information, then primary importance information obtainment unit 301 frequently obtains height Accuracy positional information but be to increase power consumption.On the other hand, if extending monitoring period, i.e. Reduce the acquisition frequency of positional information, then primary importance information obtainment unit 301 obtains high accuracy position The chance of confidence breath reduces, but can reduce power consumption.

In an embodiment, monitoring period control unit 303 is based on from mobile detector unit 304 and meter The output of counting unit 305 controls monitoring period.It is single that mobile detector unit 304 detects positional information detection Whether unit's 216 (or primary importance information obtainment unit 301) move.

Predetermined value is there is in mobile detector unit 304 in the position of primary importance information obtainment unit 301 Or detect that primary importance information obtainment unit 301 moves during bigger change.If it is additionally, mobile Detector unit 304 detects the movement of primary importance information obtainment unit 301, then monitoring period controls Unit 303 shortens monitoring period further so that primary importance information obtainment unit 301 increases position The acquisition frequency of information.This is because the change of position is big, it is necessary to short in frequent moving state Cycle detection positional information.On the other hand, if mobile detector unit 304 is not detected by primary importance The movement of information obtainment unit 301, then monitoring period control unit 303 extends monitoring period so that Primary importance information obtainment unit 301 dips the acquisition frequency of information.This is because the change of position Change little, even and if position can also be obtained with enough accuracys with long period in infrequently moving state Information.

It addition, when mobile detector unit 304 is because mobile detector unit 304 is not detected by first After putting the movement of information obtainment unit 301 and temporarily extending monitoring period, again detect first When putting information obtainment unit 301 mobile, mobile detector unit 304 is detected by counting unit 305 The time period of the movement of positional information detector unit 216 counts.If it addition, the time period reaches Predetermined value (counting 1), then monitoring period control unit 303 makes monitoring period return to short monitoring period, Primary importance information obtainment unit 301 is made again to increase the acquisition frequency of positional information.

So, if mobile detector unit 304 detects primary importance information obtainment unit 301 again Movement, change the most at once, but count down to special time period (counting 1) in counting unit 305 Change the monitoring period of primary importance information obtainment unit 301 afterwards.Therefore, counting unit 305 By to primary importance information obtainment unit 301 change positional information obtain frequency transition stage to Go out delayed steady statue change in play a role.

There is primary importance information obtainment unit 301 cannot be in such as indoor place or the nothing of basement The region of method reception gps signal obtains the situation of positional information.Positional information obtains and determines unit 306 determine whether primary importance information obtainment unit 301 obtains positional information.

If positional information obtains determines that unit 306 determines that primary importance information obtainment unit 301 does not obtains Obtain positional information, then second switch status unit 308 controls second position information obtainment unit 302 enter open state so that at the acquisition of second position information obtainment unit 302 start position information Reason.In other words, second position information obtainment unit 302 can be at primary importance information obtainment unit The acquisition of kind of supplemental position information in 301 regions that cannot obtain positional information.

It addition, positional information is obtained by counting unit 305 determines that unit 306 determines primary importance information Obtain unit 301 to obtain time period of positional information and count.Monitoring period control unit 303 control primary importance information obtainment unit 301 based on this time period obtains the frequency of positional information. Such as, if primary importance information obtainment unit 301 is moved to such as indoor place or basement The place of gps signal cannot be received, then for the viewpoint of power consumption etc., primary importance information Although it is useless for obtaining unit 301 and not obtaining positional information but frequently obtain positional information.Therefore, Mobile detector unit 304 detects the movement of primary importance information obtainment unit 301, additionally, counting is single Unit 305 cannot obtain the time period of positional information and count primary importance information obtainment unit 301 Number, if the time period exceedes predetermined value (counting 2), then monitoring period control unit 303 extends prison Apparent cycle, to reduce by the primary importance information obtainment unit 301 acquisition frequency to positional information.

So, if primary importance information obtainment unit 301 cannot obtain positional information, the most at once Change but change first after counting unit 305 count down to special time period (counting 2) Put the monitoring period of information obtainment unit 301.Therefore, counting unit 305 is by believing to primary importance Breath acquisition unit 301 changes the transition stage of positional information acquisition frequency and is given delayed, in steady statue Transformation plays a role.

It addition, when mobile detector unit 304 detects that primary importance information obtainment unit 301 does not moves, And positional information obtains and determines that unit 306 determines that primary importance information obtainment unit 301 cannot obtain position During confidence breath, the first on off state control unit 307 controls primary importance information obtainment unit 301 Enter off status so that the acquisition of positional information processes and stops.Such as, in primary importance information acquisition What unit 301 was present in such as indoor place or basement cannot receive at the place of gps signal also Also in the case of being not moved, it is impossible to use gps receiver to obtain positional information.To this end, pass through Positional information the above feelings being also not moved cannot be obtained at primary importance information obtainment unit 301 Condition stops the operation of gps receiver to reduce power consumption.

On the other hand, pass is entered when mobile detector unit 304 at primary importance information obtainment unit 301 State is to stop detecting in the state that acquisition processes the movement of primary importance information obtainment unit 301 Time, the first on off state control unit 307 controls primary importance information obtainment unit 301 entrance and opens shape State so that primary importance information obtainment unit 301 obtains positional information again.Such as, if first Positional information acquisition unit 301 moves to receive due to primary importance information obtainment unit 301 The place of gps signal, so starting to believe from the GPS that cannot receive in such as indoor place or basement Number place move, then by recover primary importance information obtainment unit 301 operation attempt obtain height Accuracy positional information.It addition, monitoring period control unit 303 is at primary importance information obtainment unit 301 recover to determine monitoring period when position acquisition processes.In an embodiment, it is assumed that obtain recovering position Short monitoring period is set when must process.

Herein, if positional information obtains determines that unit 306 is at second position information obtainment unit 302 Determine when being in open state that primary importance information obtainment unit 301 obtains positional information, then second open Off status control unit 308 controls second position information obtainment unit 302 and enters off status, to stop Positional information acquisition processes.If this is because primary importance information obtainment unit 301 can obtain relatively High accuracy positional information, then second position information obtainment unit 302 there is no need to obtain position letter Breath.

Position output select unit 309 uses positional information acquisition to determine that unit 306 determines primary importance Which acquisition position letter in information obtainment unit 301 and second position information obtainment unit 302 Breath, and select which output position information.It addition, when primary importance information obtainment unit 301 When obtaining positional information with the both of which in second position information obtainment unit 302, select output accurately The positional information from primary importance information obtainment unit 301 that property is higher.If positional information obtains Determine that unit 306 determines that primary importance information obtainment unit 301 obtains positional information, then position output Select unit 309 can select the output from primary importance information obtainment unit 301.It addition, such as Really positional information obtains and determines that unit 306 controls second due to second switch status unit 308 Put information obtainment unit 302 and enter open state, so determining primary importance information obtainment unit 301 Cannot obtain positional information, then position output select unit 309 can select from second position information Obtain the output of unit 302.Additionally, there are for from primary importance information obtainment unit 301 One positional information obtains after unit 301 is converted into the state not obtaining positional information and obtains soon The special time period that the state of positional information rises, primary importance information obtainment unit 301 position obtained The accuracy of confidence breath can be higher than the positional information obtained by second position information obtainment unit 302 The situation of accuracy.Therefore, position output select unit 309 can be at primary importance information acquisition list Unit 301 exports during being converted into after the state not obtaining positional information special time period soon The positional information finally obtained by primary importance information obtainment unit 301.It addition, special time period Length can change based on the displacement detected by mobile detector unit 304.

The output control output primary importance letter that switch 310 selects based on position output select unit 309 Breath obtains unit 301 and which positional information of second position information obtainment unit 302, thus obtains Final position information.

Fig. 4 schematically shows another internal profile instance of positional information detector unit 216.With with The mode that Fig. 3 is similar to, it is shown that positional information detector unit 216 include primary importance information acquisition list Unit 401, second position information obtainment unit 402, monitoring period control unit 403, mobile detection Unit 404, counting unit 405, positional information obtain and determine unit 406, control primary importance letter Breath obtains the first on off state control unit 407 of unit 401 on off state, controls second confidence Breath obtains the second switch status unit 408 of unit 402 on off state, position output selects single Unit 409 and switch 410.Substantially operate in the way of as the profile instance shown in Fig. 3 Each functional module 401 to 410.In the example illustrated, mobile detector unit 404 includes acceleration Detector unit 404-1 and metrics calculation unit 404-2.Hereinafter, will be based primarily upon with Fig. 3's Difference describes each unit.

Acceleration detecting unit 404-1 detection is by adding that the movement of primary importance acquisition unit 401 causes Speed.It addition, metrics calculation unit 404-2 is based on adding of being detected by acceleration detecting unit 404-1 Speed, is calculated and is carried out by the constant motion of such as acceleration or uniform motion for the scheduled time Displacement.

Monitoring period control unit 403 obtains based on the primary importance calculated by metrics calculation unit 404-2 The displacement obtaining unit 401 controls the monitoring period of primary importance information obtainment unit 401.Herein, Monitoring period control unit 403 arranges one or more threshold value, and the displacement in the scheduled time surpasses In the case of crossing threshold value, control to shorten monitoring period, i.e. make primary importance obtain unit 401 Increase the frequency that positional information acquisition processes.Comparatively speaking, if the displacement of the scheduled time is less than Threshold value, then monitoring period control unit 403 controls to extend monitoring period, i.e. primary importance is obtained Obtain unit 401 and reduce the frequency that positional information acquisition processes.

It addition, counting unit 405 is by monitoring period, (that is, primary importance obtains unit 401 Change positional information obtain frequency transition stage) be given delayed steady statue change in play a role (described above).

Additionally, mobile detector unit 404 can the side of including in addition to acceleration detecting unit 404-1 Position detector unit (not shown).In this case, it is possible to use from acceleration detecting unit 404-1 The acceleration information obtained and the azimuth information obtained from orientation detection unit, by based on by first Position obtains the movement of the positional information calculation primary importance acquisition unit 401 that unit 401 finally detects Information estimates positional information.When not receiving gps signal, and primary importance obtains unit 401 When cannot obtain positional information, position output select unit 409 is preferably chosen use acceleration information The information higher with the accuracy of the positional information of azimuth information acquisition, and obtained single by the second position The positional information that unit 402 obtains, to export.

Fig. 5 illustrates that in the positional information detector unit 216 shown in Fig. 3 or Fig. 4, state changes flow process Example.In same figure, " GPS opens 1 " indicates at primary importance information obtainment unit 301 The middle state arranging short monitoring period, " GPS opens 2 " indicates at primary importance information obtainment unit 301 The middle state arranging long monitoring period, " GPS pass " indicates by primary importance information obtainment unit 301 Acquisition to positional information is in off status, and " NW opens " instruction is obtained by second position information Obtaining unit 302 to be in the acquisition of positional information in open state, " NW pass " indicates by second Positional information obtain unit 302 acquisition of positional information is in off status (be the most also as This).

If it is the position detection process carried out by positional information detector unit 216 (501), then first First, flow process proceeds to be processed the acquisition of positional information by primary importance information obtainment unit 301 (502).In this state, primary importance information obtainment unit 301 arranges short monitoring period (GPS opens 1), and operation stopping (NW pass) of second position information obtainment unit 302.

Herein, if positional information obtains determines that unit 306 determines primary importance information obtainment unit 301 obtain positional information, then maintain this state (502).

If it addition, in this state (502), positional information obtains and determines that unit 306 determines the One positional information obtains unit 301 and obtains positional information, and mobile detector unit 304 detects first Positional information obtains unit 301 and does not moves, then monitoring period control unit 303 is in primary importance information Obtain and unit 301 arranges long monitoring period (GPS opens 2), and flow process forwards positional information to and obtains The reduction of frequency processes (503).Owing to primary importance information obtainment unit 301 is difficult to mobile, so Low power consumption is realized by reducing the frequency using gps signal to obtain position.Manage the most in this place (503), in, second position information obtainment unit 302 stops operation (NW pass).

In this place in reason (503), if mobile detector unit 304 is detecting primary importance information Obtain after unit 301 does not moves and again detect that primary importance information obtainment unit 301 moves, then Counting unit 305 detects the shifting of primary importance information obtainment unit 301 to mobile detector unit 304 The dynamic time period counts.If it addition, the time period reaches predetermined value (counting 1), then flow process Returning to monitoring period control unit 303 makes monitoring period return to short monitoring period (GPS opens 1), makes Obtain primary importance information obtainment unit 301 and again increase the process (502) of positional information acquisition frequency.

Fig. 6 illustrate Fig. 3 or or the positional information detector unit 216 shown in 4 in state change flow process Another example.

If it is the position detection process carried out by positional information detector unit 216 (501), then first First, flow process proceeds to be processed the acquisition of positional information by primary importance information obtainment unit 301 (502).In a state, primary importance information obtainment unit 301 arranges short monitoring period (GPS opens 1), and operation stopping (NW pass) of second position information obtainment unit 302.

Herein, if positional information obtains determines that unit 306 determines primary importance information obtainment unit 301 obtain positional information, then maintain this state (502).

If it addition, in this state (502), positional information obtains and determines that unit 306 determines the One positional information obtains unit 301 and obtains positional information, and mobile detector unit 304 detects first Positional information obtains unit 301 and does not moves, then monitoring period control unit 303 is in primary importance information Obtaining in unit 301 and arrange long monitoring period (GPS opens 2), flow process forwards positional information to and obtains frequency The reduction of rate processes (503).Although primary importance information obtainment unit 301 can receive GPS letter Number, but owing to primary importance information obtainment unit 301 is difficult to mobile, so using GPS by reducing The frequency of signal acquisition position realizes low power consumption.The most in this place in reason (503), the second position Information obtainment unit 302 stops operation (NW pass).

In this place in reason (503), if mobile detector unit 304 is detecting primary importance information Obtain after unit 301 does not moves and again detect that primary importance information obtainment unit 301 moves, then Counting unit 305 detects the shifting of primary importance information obtainment unit 301 to mobile detector unit 304 The dynamic time period counts.If it addition, the time period reaches predetermined value (counting 1), then flow process Returning to monitoring period control unit 303 makes monitoring period return to short monitoring period (GPS opens 1), makes Obtain primary importance information obtainment unit 301 and again increase the process (502) of positional information acquisition frequency.

On the other hand, in this place in reason (502), if positional information obtains determines that unit 306 is true Determine primary importance information obtainment unit 301 and cannot obtain positional information, then flow process forwards to except by first Positional information obtains unit 301 and the acquisition of positional information processes the second position outside (GPS opens 1) The operation (NW opens) that information obtainment unit 302 start position information acquisition processes, and hold parallel Row by primary importance information obtainment unit 301 and second position information obtainment unit 302 to positional information Acquisition process process (504).

In this place in reason (504), if positional information obtains determines that unit 306 determines primary importance Information obtainment unit 301 obtains positional information, then by second position information obtainment unit 302 to position The operation that the acquisition of information processes stops (NW pass), and flow process returns to process (502).

Fig. 7 illustrates that in the positional information detector unit 216 shown in Fig. 3 or Fig. 4, state changes flow process Yet another embodiment.

If (501), then example the position detection process carried out by positional information detector unit 216 As, flow process forwards to, by primary importance information obtainment unit 301, the acquisition of positional information is processed (502). In a state, primary importance information obtainment unit 301 arranges short monitoring period (GPS opens 1), And the operation of second position information obtainment unit 302 stops (NW pass).

Herein, if positional information obtains determines that unit 306 determines primary importance information obtainment unit 301 obtain positional information, then maintain this state (502).

It addition, in this state (502), if positional information obtains determines that unit 306 determines the One positional information obtains unit 301 and obtains positional information, and mobile detector unit 304 detects first Positional information obtains unit 301 and does not moves, then monitoring period control unit 303 is in primary importance information Obtain and unit 301 arranges long monitoring period (GPS opens 2), and flow process forwards positional information to and obtains The reduction of frequency processes (503).Although primary importance information obtainment unit 301 can receive GPS Signal, but owing to primary importance information obtainment unit 301 is difficult to mobile, so being used by reduction Gps signal obtains the frequency of position and realizes low power consumption.The most in this place in reason (503), second Positional information obtains unit 302 and stops operation (NW pass).

In this place in reason (503), if mobile detector unit 304 is detecting primary importance information Obtain after unit 301 does not moves and again detect that primary importance information obtainment unit 301 moves, then Counting unit 305 detects the shifting of primary importance information obtainment unit 301 to mobile detector unit 304 The dynamic time period counts.If it addition, the time period reaches predetermined value (counting 1), then flow process Return to monitoring period control unit 303 make monitoring period return to short monitoring period (GPS opens 1) so that Obtain primary importance information obtainment unit 301 and again increase the process (502) of positional information acquisition frequency.

In this place in reason (503), if positional information obtains determines that unit 306 determines primary importance Information obtainment unit 301 cannot obtain positional information, then flow process forwards monitoring period control unit 303 to Long monitoring period (GPS opens 2), the second position are set in primary importance information obtainment unit 301 The operation (NW opens) that information obtainment unit 302 start position information acquisition processes, and hold parallel Row primary importance information obtainment unit 301 and second position information obtainment unit 302 are to positional information The process (506) that acquisition processes.

In this place in reason (506), if positional information obtains determines that unit 306 determines primary importance Information obtainment unit 301 obtains positional information, then second position information obtainment unit 302 para-position confidence The operation that the acquisition of breath processes stops (NW pass), and flow process returns to process (503).

Fig. 8 illustrates that in the positional information detector unit 216 shown in Fig. 3 or Fig. 4, state changes flow process Yet another embodiment.

If the position detection that positional information detector unit 216 is carried out processes start (501), first, Flow process forwards primary importance information obtainment unit 301 to and the acquisition of positional information is processed (502).At this In state, primary importance information obtainment unit 301 arranges short monitoring period (GPS opens 1), The operation of second position information obtainment unit 302 stops (NW pass).

Herein, if positional information obtains determines that unit 306 determines primary importance information obtainment unit 301 obtain positional information, then maintain this state (502).

On the other hand, in this place in reason (502), if positional information obtains determines that unit 306 is true Determine primary importance information obtainment unit 301 and cannot obtain positional information, then flow process forwards to except first Put information obtainment unit 301 and the acquisition of positional information is processed second confidence outside (GPS opens 1) Breath obtains the operation (NW opens) that unit 302 start position information acquisition processes, and executed in parallel the One positional information obtains unit 301 and the second position information obtainment unit 302 acquisition to positional information The process (504) processed.

In this place in reason (504), if positional information obtains determines that unit 306 determines primary importance Information obtainment unit 301 obtains positional information, then second position information obtainment unit 302 para-position confidence The operation that the acquisition of breath processes stops (NW pass), and flow process returns to process (502).

It addition, in this place in reason (504), if mobile detector unit 304 detects the further One positional information obtains unit 301 and does not moves, then flow process forwards primary importance information obtainment unit 301 to Enter off status (GPS pass), and only second position information obtainment unit 302 performs positional information The process (505) that acquisition processes.In cannot receiving gps signal the state that also do not moves, One positional information obtains unit 301 can be changed to be able to receive that the state probability of gps signal is the least. Therefore, by stopping using gps signal acquisition position to realize low power consumption.

In this place in reason (505), if mobile detector unit 304 detects that primary importance information obtains Obtain the movement of unit 301, then flow process returns to primary importance information obtainment unit 301 and enters open state (GPS opens 1), and executed in parallel primary importance information obtainment unit 301 and second position information obtains Obtain the process (504) that the acquisition of positional information is processed by unit 302.

Fig. 9 illustrates that in the positional information detector unit 216 shown in Fig. 3 or 4, state changes flow process Yet another embodiment.

If positional information obtains determines that unit 306 determines that primary importance information obtainment unit 301 does not obtains Obtain positional information, and mobile detector unit 304 detects the shifting of primary importance information obtainment unit 301 Dynamic, then can be possible according to the mobile gps signal that receives, thus primary importance information acquisition list Unit 301 can obtain positional information.Therefore, flow process enters except primary importance information obtainment unit The acquisition of 301 pairs of positional informationes processes second position information obtainment unit 302 outside (GPS opens 1) The operation (NW opens) that start position information acquisition processes, and executed in parallel primary importance information acquisition The state that the acquisition of positional information is processed by unit 301 and second position information obtainment unit 302 (504)。

In this state (504), if mobile detector unit 304 detects that primary importance information obtains Obtain unit 301 not move, then primary importance information obtainment unit 301 can be changed to be able to receive that GPS The state of signal is unlikely that.Therefore, flow process forwards primary importance information obtainment unit 301 to Enter off status (GPS pass), and only second position information obtainment unit 302 performs positional information The process (505) that acquisition processes.

In this place in reason (504), if mobile detector unit 304 detects that primary importance information obtains Obtaining the movement of unit 301, positional information obtains and determines that unit 306 determines primary importance information acquisition list Unit 301 cannot obtain positional information, and counting unit 305 is to primary importance information obtainment unit 301 nothing The time period of method acquisition positional information counts, and the time period exceedes predetermined value (counting 2), then Flow process forwards monitoring period control unit 303 to and arranges long prison in primary importance information obtainment unit 301 Apparent cycle (GPS opens 2), and executed in parallel primary importance information obtainment unit 301 and second Put the process (506) that the acquisition of positional information is processed by information obtainment unit 302.Even if due to One positional information acquisition unit 301 also cannot be expected in the case of moving can receive gps signal, So realizing low power consumption by reducing the frequency using gps signal to obtain position.

It addition, manage in this place in (506), if primary importance information obtainment unit 301 cannot obtain Obtain positional information, but mobile detector unit 304 also detects that primary importance information obtainment unit 301 Do not move, then flow process forwards primary importance information obtainment unit 301 to and enters off status, and only second Positional information obtains unit 302 and performs the process (505) that positional information acquisition processes.Due to first Put information obtainment unit 301 in the state not moved, be changed to be able to receive that the state of gps signal It is unlikely that, so realizing low power consumption by stopping using gps signal to obtain position.

It addition, Figure 10 illustrates that in the positional information detector unit 216 shown in Fig. 3 or 4, state turns The yet another embodiment of variable flow.

If the position detection that positional information detector unit 216 is carried out processes start (501), first, Flow process forwards primary importance information obtainment unit 301 to and the acquisition of positional information is processed (502).At this In state, primary importance information obtainment unit 301 arranges short monitoring period (GPS opens 1), The operation of second position information obtainment unit 302 stops (NW pass).

Herein, if positional information obtains determines that unit 306 determines primary importance information obtainment unit 301 obtain positional information, then maintain this state (502).

It addition, in this state (502), if positional information obtains determines that unit 306 determines the One positional information obtains unit 301 and obtains positional information, and mobile detector unit 304 detects first Positional information obtains unit 301 and does not moves, then monitoring period control unit 303 is in primary importance information Obtaining in unit 301 and arrange long monitoring period (GPS opens 2), flow process forwards positional information to and obtains frequency The reduction of rate processes (503).The most in this process, second position information obtainment unit 302 stops behaviour Make (NW pass).

In this place in reason (503), if mobile detector unit 304 is detecting primary importance information Obtain after unit 301 does not moves and again detect that primary importance information obtainment unit 301 moves, then Counting unit 305 detects the shifting of primary importance information obtainment unit 301 to mobile detector unit 304 The dynamic time period counts.If it addition, the time period reaches predetermined value (counting 1), then flow process Return to monitoring period control unit 303 make monitoring period return to short monitoring period (GPS opens 1) so that Obtain primary importance information obtainment unit 301 and again increase the process (502) of positional information acquisition frequency.

So, by change after counting down to special time period (counting 1) in counting unit 305 the One positional information obtains the monitoring period of unit 301 and primary importance information obtainment unit 301 is changed Positional information obtains the transition stage of frequency and has delayed, such that it is able to prevent at very altofrequency generation Reason (502) and the transformation processed between (503).

On the other hand, in this place in reason (502), if positional information obtains determines that unit 306 is true Determine primary importance information obtainment unit 301 and cannot obtain positional information, then flow process forwards to except first Put information obtainment unit 301 and the acquisition of positional information is processed second confidence outside (GPS opens 1) Breath obtains the operation (NW opens) that unit 302 start position information acquisition processes, and executed in parallel the One positional information obtains unit 301 and the second position information obtainment unit 302 acquisition to positional information The process (504) processed.

In this place in reason (504), if positional information obtains determines that unit 306 determines primary importance Information obtainment unit 301 obtains positional information, then second position information obtainment unit 302 para-position confidence The operation that the acquisition of breath processes stops (NW pass), and flow process returns to process (502).

It addition, in this place in reason (504), if mobile detector unit 304 detects the further One positional information obtains unit 301 and does not moves, then flow process forwards primary importance information obtainment unit 301 to Enter off status (GPS pass), and only second position information obtainment unit 302 performs positional information The process (505) that acquisition processes.

In this place in reason (505), if mobile detector unit 304 detects that primary importance information obtains Obtain the movement of unit 301, then flow process returns to primary importance information obtainment unit 301 and enters open state (GPS opens 1), and executed in parallel primary importance information obtainment unit 301 and second position information obtains Obtain the process (504) that the acquisition of positional information is processed by unit 302.

In this place in reason (504), if mobile detector unit 304 detects that primary importance information obtains Obtaining the movement of unit 301, positional information obtains and determines that unit 306 determines primary importance information acquisition list Unit 301 cannot obtain positional information, and counting unit 305 is to primary importance information obtainment unit 301 nothing The time period of method acquisition positional information counts, and the time period exceedes predetermined value (counting 2), then Flow process forwards monitoring period control unit 303 to and arranges long prison in primary importance information obtainment unit 301 Apparent cycle (GPS opens 2), and executed in parallel primary importance information obtainment unit 301 and the second position The process (506) that the acquisition of positional information is processed by information obtainment unit 302.

So, by change after counting down to special time period (counting 2) in counting unit 305 the One positional information obtains the monitoring period of unit 301 and primary importance information obtainment unit 301 is changed Positional information obtains the transition stage of frequency and has delayed, such that it is able to prevent at very altofrequency generation Reason (504) and the transformation processed between (505).

In this place in reason (506), if primary importance information obtainment unit 301 cannot obtain position The most mobile detector unit 304 of information also detects that primary importance information obtainment unit 301 does not moves, Then flow process forwards primary importance information obtainment unit 301 to and enters off status, and only second position information Obtain unit 302 and perform the process (505) that positional information acquisition processes.
