Description
[technical field]
The present invention relates to be built in the step number measuring device of pocket telephone etc. or signal of sensor taken a sample and carry out the technology of wave form analysis.
[background technology]
In pocket telephone, exist except pocket telephone function originally, also have a type as the function of the step number measuring device that the carrier's of pocket telephone step number is carried out instrumentation.In the pocket telephone that has as the function of step number measuring device, built-inly detect the acceleration transducer of the acceleration that results from this pocket telephone or utilize the output signal of its acceleration transducer to detect the circuit etc. of carrier's walking according to coming on foot of carrier.Therefore, have as the pocket telephone of the function of step number measuring device and compare with the pocket telephone that does not possess this function, consumes electric power increases.In TOHKEMY 2010-15414 communique and TOHKEMY 2009-300329 communique, the technology of the consumes electric power that is used to suppress this pocket telephone is disclosed.
The disclosed pocket telephone of TOHKEMY 2010-15414 communique except the control part of performance as the effect of this pocket telephone control maincenter, also has acceleration transducer and instrumentation portion.Acceleration transducer output expression is by the accekeration of the acceleration of this pocket telephone generation.Instrumentation portion resolves the waveform from the accekeration of acceleration transducer output, judges whether the walking figure continues the stipulated time, under result of determination is sure situation, and the action of beginning under the normal mode that carries out the step number instrumentation.Under the situation that control part stopped in fix time from the notice lion indicator of the step number of instrumentation portion (for example 5 seconds), the processing of the instrumentation of the step number in the instrumentation portion is stopped.According to this technology, compare with the situation of instrumentation portion perseveration all the time, suppressed consumes electric power.
The disclosed pocket telephone of TOHKEMY 2009-300329 communique except the control part of performance as the effect of the control maincenter of this pocket telephone, also has acceleration transducer.This acceleration transducer is built-in with counter.Acceleration transducer surpasses carrier's walking of regarding this pocket telephone under the situation of stipulated standard value as, the enumeration data in the counter that adds at the acceleration that self produces.In addition, control part is compared between the little sleep of consumes electric power (sleep) state at starting state and with this starting state and is changed, and when becoming starting state, reads the enumeration data in the counter in the acceleration transducer.And control part upgrades the step number in the storage part in this control part according to this enumeration data, makes the step number after the renewal be shown in basic display unit.According to this technology, carry out the situation of the instrumentation of step number with making control part keep starting state and compare, suppressed consumes electric power.
In addition; Following passometer is disclosed in japanese kokai publication hei 7-191603 communique; Promptly; On the output signal of acceleration transducer, apply wave form analysis (whether show with walking in corresponding specific waveform graph of a step judgement or whether show the judgement etc. that goes on foot corresponding peak value with) detect step of the carrier of this passometer, add up the processing of step number.
Yet; In the technology of TOHKEMY 2010-15414 communique; In order to carry out whether should changing into the judgement of starting state from sleep state; Carry out the walking figure and whether continue above judgement of stipulated time,, have the problem of the consumes electric power that is difficult to fully reduce the instrumentation portion under the sleep state so the operand of the instrumentation portion under the sleep state is big.In addition; In the technology of TOHKEMY 2010-15414 communique; The walking figure continues under the situation of stipulated time under sleep state; Normal mode to carrying out the step number instrumentation changes, so it is elongated to the time delay (latency) of beginning step number instrumentation to begin walking from the carrier, has the step number instrumentation inaccurate problem that becomes.In addition; In the technology of TOHKEMY 2009-300329 communique; Owing to need make acceleration transducer one direct acting that is built-in with counter in advance; So,, also have the problem that can't reduce as the whole consumes electric power of acceleration transducer and control part even if can reduce the consumes electric power of control part through drive control part off and on.
In addition, suppress lowlyer, consider to stop acceleration transducer being supplied power inferring under the situation of (not walking) of not moving for the carrier of passometer in order to realize the required electric power of function of passometer by using.It for example is following situation; That is, acceleration transducer is supplied power off and on, only infer the carrier and carry out under the situation of certain action in the situation of the sampling value that to surpass predetermined threshold value etc.; Continuation is supplied power to acceleration transducer, carries out detailed wave form analysis.
But; In the mode of off and on acceleration transducer being supplied power during till the output signal of acceleration transducer surpasses defined threshold; When acceleration when the idle period of time that electric power is intermittently supplied with surpasses defined threshold; In fact from acceleration surpass threshold value the time be carved into the variable length delay that the wave form analysis of acceleration sensor outputs signals is performed; In fact omission acceleration just surpassed waveform graph or peak value after moment of threshold value, exist the mensuration result of step number to produce the situation (with reference to the curve map shown in the dotted line among Fig. 7) of error.But, stop then can shortening above-mentioned delay to during the acceleration transducer power supply if shorten, still, from the viewpoint that will realize that the required electric power of function of passometer by using suppresses lowlyer, shortening stops unsatisfactory during the acceleration transducer power supply.

MCU41 is the control maincenter of this step number measuring device 40.MCU41 carries out the pedometer measuring program that is stored in ROM43 when RAM42 is utilized as the perform region.That kind as shown in Figure 4, MCU41 changes between holding state and these two states of instrumentation state according to the pedometer measuring program.Fig. 5 is the process flow diagram of the processed content of the performed pedometer measuring program of expression MCU41.That kind as shown in Figure 5, MCU41 at first is made as holding state (S101) with pattern.Under holding state; MCU41 serves as to carry out off and at interval the electric power of acceleration transducer 44 is supplied with time T 3 (for example establishing the T3=200 millisecond); And; Obtain accekeration data DA from acceleration transducer 44, whether (threshold value TH1 is made as force of gravity acceleration (9.8m/s above threshold value TH1 to judge these accekeration data DA
2) big slightly value), determining accekeration data DA, change the instrumentation state into above under the situation of threshold value TH1.More specifically, MCU41 carries out following processing under holding state.
At first, MCU41 carries out supplying with (S102) to the power supply of acceleration transducer 44.Then, MCU41 obtains accekeration data DA (S103) from acceleration transducer 44.These accekeration data DAM is stored in the built-in register (storage area of the accekeration data DA of an amount of storage) of MCU41.That is to say the effect of the sampling mechanism that the MCU41 performance of moving according to the pedometer measuring program is taken a sample to the output signal of acceleration transducer 44.
Then, MCU41 moves determination processing (S104).The action determination processing is the processing of judging whether pocket telephone 10 moves.In this action determination processing, accekeration data DA and threshold value TH1 that MCU41 relatively obtains at step S103.And, surpass under the situation of threshold value TH1 at accekeration data DA, be regarded as pocket telephone 10 and move, under the situation below the threshold value TH1, it is static to be regarded as pocket telephone 10.
MCU41 is being judged to be accekeration data DA above (S104:No) under the situation of threshold value TH1 in step S104, the power supply that stops acceleration transducer 44 is carried out is supplied with (S105).Supply with the consumption of the battery of having avoided causing 60 through stopping like this because of acceleration transducer 44 to the power supply of acceleration transducer 44.MCU41 makes after acceleration transducer 44 stops, and standby is until elapsed time T3 (S106).MCU41 judges the operation (S107) of the instrumentation end of whether having carried out the indication step number after elapsed time T3.MCU41 is back to step S102 and makes acceleration transducer 44 startings under the situation of the operation that the instrumentation of indicating step number finishes (S107:No), carries out later processing repeatedly.On the other hand, MCU41 finishes whole processing under the situation of the operation that the instrumentation that has carried out the indication step number finishes (S107:Yes).
MCU41 is judging that accekeration data DA surpasses under the situation of threshold value TH1 (S104:Yes), is transformed into instrumentation state (S201) in step S104.MCU41 is under the instrumentation state; Maintenance carries out power supply to acceleration transducer 44 to be supplied with, and obtains from the accekeration data DA of sensor 44 outputs, carries out the instrumentation of step number Num based on the regulation number accekeration data DA before being obtained; And; Carry out the whether static static judgement of pocket telephone 10,, change holding state into being judged to be under the static situation.If more specifically describe, MCU41 handles under the instrumentation state as follows.
At first; MCU41 obtains from the accekeration data DA (S202) of acceleration transducer 44 outputs; The accekeration data DA that is obtained is written to the circular buffer (as the storage area that can store afore mentioned rules number accekeration data DA, at the storage area that does not have to rewrite successively from old accekeration data DA under the situation of idle space) in the RAM42.The reason of storage accekeration data DA is in circular buffer, carries out the wave form analysis to the time waveform of acceleration based on the accekeration data DA that is stored in this circular buffer.
Then, MCU41 carries out step number instrumentation processing (S203).The step number instrumentation is treated to following processing, that is, utilize the regulation number accekeration data DA before in the circular buffer that is written in the RAM42 to judge whether carried out the walking in a step by the carrier, under the situation of walking, and the step number Num among the RAM42 that adds.If more specifically describe; In the step number instrumentation is handled; Regulation number accekeration data DA before in the MCU41 scanning circular buffer and carry out wave form analysis (being the size of accekeration data DA transfers the peak value of decline to from rising detection) in this embodiment; Detecting under the situation of peak value, be regarded as the carrier and carried out walking, making the step number Num among the RAM42 add 1.In addition, in this embodiment, be illustrated, but also can be the disclosed mode of carrying out test pattern of japanese kokai publication hei 7-191603 communique of above-mentioned expression prior art carry out the situation that peak value detects as a mode of wave form analysis.
In the step S204 after step S203, MCU41 carries out static determination processing.Static determination processing is the processing of judging that pocket telephone 10 is whether static.In static determination processing, MCU41 compares up-to-date regulation number accekeration data DA and the threshold value TH1 in the circular buffer that is written to RAM42.And, be lower than up-to-date regulation number accekeration data DA whole under the situation of threshold value TH1, it is static to be regarded as pocket telephone 10, under the situation that is not lower than threshold value TH1, is regarded as pocket telephone 10 and moves as yet.
MCU41 being judged to be under the static situation of pocket telephone 10 (S204:Yes), is transformed into holding state in step S204.On the other hand, MCU41 is being judged to be under the not static situation of pocket telephone 10 (S204:No) in step S204, and standby until elapsed time T4 (T4＜T3: for example T4=40 millisecond) (S205).And MCU41 judges the operation (S206) of the instrumentation end of whether having carried out the indication step number after elapsed time T4.MCU41 is back to step S202 and obtains from the up-to-date accekeration data DA of acceleration transducer 44 outputs under the situation of the operation that the instrumentation of indicating step number finishes (S206:No), carries out the later processing of step S203 repeatedly.In addition, MCU41 finishes whole processing under the situation of the operation that the step number instrumentation that has carried out indicating this step number measuring device 40 finishes (S206:Yes).
Stand-by time T4 among the step S205 confirms as follows; Promptly; In the cycle of obtaining of the accekeration data DA that confirms by the required T.T. TB of step S202～S205, become cycle of the abundant weak point of the degree that in the step number instrumentation is handled, can not hinder judgement whether to improve to have gone a step.Promptly; That kind as shown in Figure 6; The cycle of obtaining at the accekeration data DA that can not hinder judgement whether to improve to have gone a step is under the situation of T2, and the time of required time TB that deducts the processing of step S202～S204 from this cycle T 2 becomes the stand-by time T4 the step S205.On the other hand; Under holding state; Whether do not improve and to have gone the judgement in a step; And only carry out the judgement whether accekeration data DA surpasses threshold value TH1, so, need not to make accekeration data DA in the holding state obtain accekeration data DA under cycle T 1 and the instrumentation state to obtain cycle T 2 identical.In this embodiment, owing to reduce the consumes electric power under the holding state with doing one's utmost, so, the cycle T that obtains 1 of the accekeration under the holding state is set at than the cycle T that obtains 2 of the accekeration under the instrumentation state grows.The time of required time TA that cycle T 1 deducts the processing of step S102～S105 of obtaining of the accekeration under this holding state becomes the stand-by time the step S106.
In this embodiment of above explanation; Such shown in Fig. 6 (A); MCU41 is under holding state; Between across the stopping of time T 3, carry out off and on acceleration transducer 44 starting (S102), the accekeration data DA in the acceleration transducer 44 obtain (S103), action determination processing (S104) and acceleration transducer 44 stop (S105) this a series of processing.In addition; Such shown in Fig. 6 (B); MCU41 under the instrumentation state, across the stopping of time T 4, carry out off and in the acceleration transducer 44 accekeration data DA obtain (S202), the step number instrumentation is handled (S203) and this a series of processing of static determination processing (S204).At this, under the instrumentation state, because that the step number instrumentation is handled the operand of (step S203) is many, so, elongated as the required time TB of the integral body of step S202～S204.To this; Under holding state, only through judging that whether acceleration transducer 44 surpasses threshold value TH1 at the accekeration data DA of starting back output just, determines whether to be transformed into the instrumentation state; Thereby, until short the getting final product of the required time TA of whole processing of step S102～S105.
Therefore, the time T A that under holding state, carry out to handle by MCU41 (=T1-T3), than under the instrumentation state by MCU41 carry out the time T B that handles (=T2-T4) little.Therefore, can reduce the consumes electric power of the MCU41 under the holding state.And, in this embodiment, can the cycle T that obtain 1 of the accekeration under the holding state be set at longer than the cycle T that obtains 2 of the accekeration data DA in the instrumentation state.Therefore, according to this embodiment, can suppress the consumes electric power of step number measuring device 40.
In addition; In this embodiment and since under holding state when accekeration data DA when the threshold value TH1, change the instrumentation state at once into; So can shorten from the carrier and begin walking, can realize the for example time delay about 200ms to the time delay that begins to carry out the step number instrumentation.And, surpass threshold value TH1 and change under the situation of instrumentation state at accekeration data DA, under the instrumentation state, based on before regulation number accekeration data DA carry out whether having been undertaken the judgement of the walking in a step by the carrier.Therefore, in fact begin the carrier under the situation of walking, can not make a mistake the counting of its step number.
On the other hand, with the carrier not walking irrespectively be transformed under the situation of instrumentation state, can under the instrumentation state, not carry out the counting of step number by error.Therefore,, can shorten the time delay that begins until the step number instrumentation fully according to this embodiment, and, can when guaranteeing the instrumentation accuracy of step number, suppress the consumes electric power of step number measuring device 40.
In addition; In this embodiment; Supply with owing under the instrumentation state, continue to carry out power supply, periodically obtain accekeration data DA simultaneously, so can make under the action stable status of acceleration transducer 44 from acceleration transducer 44 to acceleration transducer 44; To guarantee that the cycle of measuring the required abundant weak point of precision obtains accekeration data DA, can carry out the step number counting exactly.
On the other hand; Under holding state; Carry out off and on the power supply of acceleration transducer 44 is supplied with, during to acceleration transducer 44 supply powers, obtain accekeration data DA, so can reduce the consumes electric power of acceleration transducer 44 from acceleration transducer 44.In this case; The accekeration data DA that under holding state, obtains from acceleration transducer 44; Be used in and whether carry out, and be not that the acceleration waveform that is used in step number counting usefulness is resolved from the judgement of holding state to the transformation of instrumentation state, so; Even, do not have harmful effect owing to driving the precise decreasing that acceleration transducer 44 causes accekeration data DA off and on yet.
More than, an embodiment of the invention are illustrated, other embodiment also can be arranged in the present invention.
(1) in the above-described embodiment, degree of will speed up Value Data DA and common threshold value TH1 compare in the static determination processing (S204) of the action determination processing (S104) of holding state and instrumentation state.But also can make threshold value that in the action determination processing, compares with accekeration data DA and the threshold value that in static determination processing, compares with accekeration data DA is different values.
(2) in addition; In the above-described embodiment; The obtaining, move of the starting of acceleration transducer 44, accekeration data DA judge and acceleration transducer 44 stop each handle; Such shown in Fig. 6 (A), carry out off and on by certain cycle (cycle T 1) across certain stopping of stand-by time T3.Under the instrumentation state, accekeration data DA obtain and the step number instrumentation is handled that each is handled, such shown in Fig. 6 (B), carry out off and on by certain cycle (cycle T 2) across stopping of time T 4.And from doing one's utmost to reduce the viewpoint of the consumes electric power under the holding state, preferably the cycle T 1 that obtains of the accekeration data DA under the holding state is grown.
Yet; If in the standby of the step S106 of above-mentioned embodiment is handled, carry out the standby of certain hour all the time; Then such shown in the dotted line among Fig. 7; Follow in the size of the acceleration of carrier's action in fact surpass the timing of threshold value TH1 and the execution regularly of the action determination processing S104 that carries out off and between produce big deviation, the time waveform at the execution timed acceleration Value Data DA of action determination processing S104 can become peak value sometimes.When the time waveform at the execution timed acceleration Value Data DA of action determination processing S104 becomes peak value; Even scanning is transformed into the accekeration data DA of the regulation quantity behind the instrumentation state; This peak value can not measured in the treatment S 203 in step number yet and be detected, and produces the mensuration mistake of the step number of step amount.So, the part of above-mentioned embodiment is carried out following modification.
As this modified example, MCU41 substitutes pedometer measuring program and the pedometer measuring program of execution graph 8 of Fig. 5 of above-mentioned embodiment.In the related step number counting procedure of this modified example, that kind as shown in Figure 8 is handled in the standby of the step S106 of Fig. 5, and the sample period adjustment that changes to step S106a is handled.Other processing is identical with the situation of Fig. 5.In this sample period adjustment treatment S 106a, MCU41 carries out the standby of stipulated time amount, and, carry out the processing of adjusting this stand-by time length according to the size of accekeration data DA.Promptly; In this modified example; For not the size of acceleration in fact surpass the timing of threshold value TH1 and the execution regularly of the action determination processing S104A that is performed off and between produce big deviation, in sample period adjustment treatment S 106a, adjust stand-by time length according to the size of accekeration data DA.In other words, the sample period of adjustment acceleration waveform.Then, the sample period adjustment treatment S 106a to the characteristic of remarkable this modified example of expression is elaborated.
Fig. 9 is the process flow diagram of the flow process of expression sample period adjustment treatment S 106A.That kind as shown in Figure 9, in this sample period adjustment treatment S 106a, at first, MCU41 judges whether the accekeration data DA that in the step S103 of Fig. 8, obtains surpasses the second threshold value TH2 (S1062) littler than above-mentioned threshold value TH1.And; MCU41 the result of determination of step S1062 be " No " situation (promptly; The situation of accekeration data DA≤second threshold value TH2) under, carry out the standby (S1064) of time T 3 (=200 milliseconds), the result of determination at step S1062 is under the situation of " Yes " on the contrary; Carry out standby (S1066), the processing that the step S107 of execution graph 8 is later than the time T 5 (for example 50 milliseconds) of time T 3 weak points.That is to say, in this modified example, the length of adjustment stand-by time, make stand-by time when accekeration data DA is bigger than threshold value TH2 than threshold value TH2 the stand-by time during greater than accekeration data DA short.
In order to carry out such sample period adjustment treatment S 106a; In the related step number measuring device 40 of this modified example; That kind shown in figure 10 is under the situation below the threshold value TH2 in the size of accekeration data DA, stopping across long time T 3 (=200 milliseconds); Carry out action determination processing S104 off and on by cycle T 1 simultaneously; When the size of accekeration data DA surpasses threshold value TH2, across the stopping of shorter time T 5 (=50 milliseconds), carries out off and on by shorter time interval T1 ' and to move determination processing S104.In this modified example, the execution interval of the action determination processing that is performed off and on is nothing but the sample interval (, sample period) the when waveform of the output signal of acceleration transducer 44 is taken a sample.That is to say that according to this modified example, near the time waveform of the acceleration the threshold value TH1 is taken a sample more carefully, can catch the moment that in fact acceleration surpasses threshold value TH1 exactly.Its result, according to this modified example, the deviation that acceleration surpasses between the execution regularly of the moment and action determination processing S104 of threshold value TH1 diminishes, and can shorten until the delay that takes place till the state-transition of instrumentation state, avoids the instrumentation of step number to omit.
(3) in addition; In the related sample period adjustment treatment S 106a of above-mentioned modified example; Relatively than little threshold value TH2 and the accekeration data DA of the action employed threshold value TH1 of determination processing S104; Under the big situation of the latter (that is, the situation of threshold value TH2＜accekeration data DA≤threshold value TH1), shorten stand-by time and the execution interval (in other words being the sample interval of acceleration waveform) of determination processing S104 under reach.But; Also can surpass in the size of accekeration data DA under the situation of threshold value TH2; Carry out greatlyyer and relatively, adjust moving the execution interval (sample interval of acceleration waveform) of determination processing more carefully than the size of little threshold value TH3 of threshold value TH1 and accekeration data DA than this threshold value TH2.Specifically, replace sample period adjustment shown in Figure 9 and handle, make MCU41 carry out sample period adjustment shown in Figure 11 and handle.
In sample period adjustment shown in Figure 11 is handled; The result of determination of step S1062 be " Yes " situation (promptly; The situation of accekeration data DA＞threshold value TH2) under, MCU41 judges whether accekeration data DA surpasses threshold value TH3 (threshold value TH3＞threshold value TH2) (S1065).And; MCU41 the result of determination of step S1065 be " No " situation (promptly; The situation of threshold value TH2＜accekeration data DA≤threshold value TH3) under, carries out the standby (S1067) of the time T 6 (for example 100 millisecond) shorter and longer than time T 5 (for example 50 milliseconds) than time T 3 (for example 200 milliseconds).Result of determination at step S1065 is that MCU41 carries out the processing (that is the standby of time T 5) of above-mentioned step S1066 under the situation (that is, the situation of threshold value TH3＜accekeration data DA＜threshold value TH1) of " Yes " on the contrary.Sample period adjustment according to shown in figure 11 is handled; The execution interval (in other words being the sample period of acceleration waveform) of action determination processing divides three phases; Under the situation of accekeration data DA≤threshold value TH2, switch to time T 3; Under the situation of threshold value TH2＜accekeration data DA≤threshold value TH3, switch to time T 6, under the situation of threshold value TH3＜accekeration data DA＜threshold value TH1, switch to time T 5.
(4) in addition; Can prepare a plurality of threshold values that separately size is littler than threshold value TH1 and differ in size from one another in advance, in the sample period, adjustment was handled, the threshold value of selecting the minimum in these a plurality of threshold values was as threshold value TH2; Carry out size relatively with accekeration data DA; With latter's wonderful works condition, reselect the second little threshold value as threshold value TH2, also can be stored in form among the ROM42 in advance; This form makes above-mentioned a plurality of threshold value corresponding separately with the scope of little ranking and distinguishing in order respectively and write the stand-by time under the situation that accekeration data DA is positioned at this scope, and adjustment is confirmed stand-by time with reference to this form in handling in the sample period.In a word, same with processing shown in Figure 11, make the size of accekeration data DA get final product near short more mode of threshold value TH1 sample period more so long as adjust the sample period.
(5) in above-mentioned embodiment and modified example, step number determinator 40 is built in pocket telephone 10.But, also can substitute it, this step number determinator 40 is built in portable terminal devices such as PDA (Personal Digital Assistant) or pocket game machine, in addition, can certainly provide step number determinator 40 as passometer.
(6) in above-mentioned embodiment and modified example, take a sample at output signal, come to be suitable for the present invention in the step number measuring device of instrumentation step number above implementing wave form analysis under the situation of threshold value TH1 in its sampling value to acceleration transducer 44.But applicable object of the present invention is not limited to the step number measuring device.If signal of sensor is taken a sample, is surpassed defined threshold carries out the wave form analysis of peak value detection etc. as condition device with its sampling value; Then through being suitable for the present invention; Can shorten from signal of sensor surpass above-mentioned threshold value the time be carved into the delay that in fact detects till this situation, do not have the ground of hysteresis and carry out wave form analysis.Particularly, the application that has been suitable for the related invention of modified example that the adjustment of related sample period of above-mentioned modified example handles is effective.In addition; As the concrete example that is suitable for beyond the passometer; Consideration is in possessing the pocket telephone of acceleration transducer; When static, carry out the processing of above-mentioned waiting status, when the carrier rocks framework etc., under the situation that starting state changes, do not have the ground of hysteresis and carry out from the transformation of waiting status to starting state.Specifically; Under waiting status, whether the sampling value of the output signal through acceleration transducer and the size between the defined threshold are the judgement of stationary state off and on relatively; And, along with above-mentioned sampling value shortens the execution interval of this judgement near above-mentioned threshold value.
