Description

  The present invention relates to a wearable device and a method for controlling the wearable device.

2. Description of the Related Art Conventionally, as a biological information measuring device that measures biological information, a measuring device that is configured in a bracelet type (watch type) attached to a wrist and measures a user's pulse rate is known (see, for example, Patent Document 1). ).
In the measuring apparatus described in Patent Document 1, the biological information of the subject (the pulse rate of the subject) is measured in accordance with predetermined measurement schedule information. The biological information measured in this way is transmitted to a biological information processing server located at a remote location via a wireless communication device, and the biological information processing server collects the transmitted biological information data and performs processing.

Patent No. 4881029

  By the way, in a wearable device that is used by being worn on a human body (for example, a wrist), the measured biological information is directly transmitted to an electronic device (for example, a smartphone that is a multi-function mobile phone) possessed by the user. It has been proposed to manage biometric information with a device.

On the other hand, wearable devices are required to be small and lightweight in order to reduce the burden on the user. For this reason, since the antenna and the like mounted on the wearable device are inevitably reduced in size, the transmission performance of biological information is also reduced in proportion to the size of the antenna.
In a wearable device equipped with such an antenna having low transmission performance, there is a possibility that measurement information cannot always be transmitted to an electronic device possessed by the user when the user is exercising their arms. If the transmission process is repeated many times until the information transmission fails, the power consumption of the battery provided in the wearable device increases, and the drive time of the wearable device is shortened.

  SUMMARY An advantage of some aspects of the invention is to provide a wearable device and a wearable device control method capable of effectively transmitting measurement information.

  The wearable device according to the first aspect of the present invention includes a behavior detection unit that detects behavior information related to a wearer's behavior, a transmission unit that transmits transmission information including the behavior information, and the transmission unit that performs the transmission by each transmission type. A storage unit that stores whether transmission information can be transmitted, an analysis unit that analyzes the action type of the wearer based on the action information, the action type of the wearer that has been analyzed, and the action type that corresponds to the action type When it is determined that the transmission information can be transmitted by the transmission availability determination unit that determines whether or not the transmission information can be transmitted based on whether or not the transmission information can be transmitted, the transmission information is A transmission control unit for transmitting to the transmission unit.

Examples of the action type include walking, running, mild housework, sitting, and resting.
According to the first aspect, based on the behavior type of the wearer analyzed based on the detected behavior information, and the transmission possibility stored in the storage unit and corresponding to the behavior type, the behavior information is obtained. When it is determined that the included transmission information can be transmitted, the transmission information is transmitted by the transmission unit.
According to this, the wearer can transmit the transmission information without performing any operation.
Further, for example, when the analyzed action type of the wearer is an action type that cannot transmit transmission information, transmission of the transmission information can be restricted, so that power consumption due to execution of useless transmission processing can be suppressed.
Therefore, the transmission information can be transmitted efficiently.

  In the first aspect, the storage unit stores the transmission propriety based on the transmission result of the transmission information by the transmission unit for each action type, and the transmission propriety determination unit includes the action type of the wearer and the transmission It is preferable to determine whether or not the transmission information can be transmitted based on availability.

  According to the first aspect, transmission permission / prohibition based on the transmission result of the transmission information by the transmission unit for each behavior type is stored in the storage unit, and the transmission permission / inhibition determination unit includes the analyzed action type of the wearer and the corresponding action type. Whether or not transmission information can be transmitted is determined based on whether or not transmission is possible. That is, the transmission permission / inhibition determining unit determines whether or not transmission information can be transmitted based on a transmission result corresponding to an action actually performed by the wearer. As a result, it is possible to determine whether or not transmission is possible in accordance with the actual use situation of the wearer. That is, since it can be determined more appropriately whether transmission information can be transmitted, execution of useless transmission processing can be suppressed. Therefore, power consumption can be reduced and the drive time of the wearable device can be extended.

  In the first aspect, the information amount determination unit determines whether the information amount of the transmission information is an information amount that can be transmitted with respect to the action type of the wearer analyzed by the analysis unit, The transmission control unit preferably regulates transmission of the transmission information by the transmission unit when the information amount determination unit determines that the amount of information is not transmittable.

Here, when the information amount of the transmission information transmitted by the transmission unit is large, there is a possibility that the communication connection is disconnected during the transmission of the transmission information. In such a case, since it becomes necessary to transmit the transmission information again, the disconnected communication, that is, the failed transmission process is wasted, which causes power consumption to increase.
On the other hand, according to the first aspect, when it is determined that the information amount of the transmission information is not the information amount that can be transmitted with respect to the analyzed action type of the wearer, the transmission control unit performs the transmission information. Transmission is regulated. According to this, it is possible to suppress execution of transmission processing that is likely to end in failure. Therefore, it is possible to reliably suppress the execution of useless transmission processing, so that it is possible to reduce power consumption and thus extend the driving time.

  In the first aspect, when it is determined by the transmission success / failure determination unit that the transmission unit has successfully transmitted the transmission information and the transmission success / failure determination unit determines that the transmission information transmission has failed, It is preferable to include a transmission rate changing unit that changes the transmission rate of the transmission information.

Here, the change of the transmission rate refers to the change of the transmission speed (transfer speed) or the change of the transmission format. For example, when the transmission information is transmitted after being divided into a plurality of packets, the former includes changing the transmission speed of each packet, and the latter includes information on each packet without changing the transmission frequency. It is possible to change the amount.
According to the first aspect, when the transmission success / failure determination unit determines that transmission of transmission information has failed, the transmission rate change unit changes the transmission rate of the transmission information.
Thereby, for example, by increasing the transmission rate, the amount of information that can be transmitted in the same time can be increased or the transmission time can be reduced as compared with transmission processing at a normal transmission rate. Therefore, the possibility that transmission information can be transmitted can be increased, and the number of useless transmission processes can be reduced. Therefore, power consumption can be reduced.

  In the first aspect, the transmission rate changing unit preferably returns the transmission rate to the transmission rate before the change when the transmission information is successfully transmitted at the changed transmission rate.

Here, when the transmission rate is high, it is necessary to execute information transmission processing in accordance with the transmission rate, so that power consumption increases.
Therefore, according to the first aspect, when the transmission information is successfully transmitted in a state where the transmission rate is changed, the transmission rate is returned to the transmission rate before the change. Thereby, it can suppress that the transmission process of the said transmission information is always performed with the changed transmission rate with high power consumption. Therefore, a useless increase in power consumption can be suppressed.

  In the first aspect, the behavior detection unit includes a biological information detection unit that detects biological information of the wearer and an acceleration detection unit that detects acceleration, and the behavior information included in the transmission information includes: It is preferable that at least the biological information is included.

In addition, as biological information, a pulse wave, body temperature, blood pressure, an electrocardiogram, an electroencephalogram, etc. can be illustrated.
According to the first aspect, the behavior detection unit includes the biological information detection unit that detects biological information, and the acceleration detection unit that detects acceleration acting on the wearer. Thereby, based on the biometric information and acceleration detected by each detection part, the action classification of a wearer's action can be determined appropriately.
Further, since the behavior information included in the transmission information includes at least biological information, the biological information can be reliably managed by a device that receives the transmission information.

The wearable device control method according to the second aspect of the present invention includes a behavior detection step of detecting behavior information related to a wearer's behavior, an analysis step of analyzing the behavior type of the wearer based on the behavior information, A determination step of determining whether or not the transmission information including the behavior information can be transmitted based on the analyzed behavior type of the wearer and whether or not transmission information for each of the behavior types stored in advance can be transmitted; And a transmission step of transmitting the transmission information when it is determined that the transmission information can be transmitted.
According to the said 2nd aspect, the effect similar to the wearable apparatus which concerns on the said 1st aspect can be show | played by applying the said control method to a wearable apparatus.

As shown in FIG. 2, such a measuring apparatus 1 includes a case 2 that constitutes an exterior. The case 2 includes a main body 21 and a pair of bands 22 and 23 that are integrally formed, and the band. And a buckle 24 attached to 22, 23.

As shown in FIG. 2, the main body portion 21 is configured in a substantially arc shape in a side view according to a portion outside the wrist 410 (a portion on the back side of the hand). A display portion 31 of the notification means 3 described later is provided on the front portion 21A of the main body portion 21. Further, the biological information detection unit 41 of the behavior detection means 4 is exposed on the back surface portion 21B opposite to the front surface portion 21A.
The pair of bands 22 and 23 extend in opposite directions from one end and the other end in the longitudinal direction of the main body 21.
The buckle 24 is an intermediate clasp called a D buckle that fixes the bands 22 and 23 when the measuring apparatus 1 is attached to the wrist 410.

  As described above, the measuring device 1 is intended to reduce the size and improve the design of the measuring device 1, and by a user's tap operation (operation of tapping the measuring device 1 with a hand or a finger). It is assumed that it is operated, and the case 2 is not provided with operation means such as buttons. However, the present invention is not limited to this, and the case 2 may be provided with operation means such as a button or a touch panel that causes the measurement apparatus 1 to execute predetermined processing.

The notification unit 3 notifies the operation state and the operation state of the measurement apparatus 1 and includes a display unit 31 and a vibration unit 32.
Among these, the vibration unit 32 has a motor controlled by a notification control unit 83 described later, and notifies the state of the measurement device 1 by vibration generated by driving the motor.

[Configuration of display section]

[Configuration of behavior detection means]
The behavior detection unit 4 corresponds to the behavior detection unit of the present invention, and includes a biological information detection unit 41 and an acceleration detection unit 42 that detect biological information and acceleration information included in the behavior information, respectively.
The biological information detection unit 41 detects the biological information of the user wearing the measuring device 1. In the present embodiment, the biological information detection unit 41 is a pulse wave detection unit that detects a pulse wave as biological information, and is exposed on the back surface part 21 </ b> B (part facing the human body) of the case 2.
Such a biological information detection unit 41 includes a photoelectric sensor including a light emitting element such as an LED and a light receiving element such as a photodiode. This photoelectric sensor irradiates light from a light emitting element toward a living body in a state where the measuring device 1 is attached to the wrist 410, and changes in light amount when the light coming through the blood vessels of the living body is received by the light receiving element. By detecting this, a pulse wave is detected. That is, the light irradiated to the living body is partially absorbed by the blood vessel, but the absorption rate in the blood vessel changes due to the influence of pulsation, and the amount of light reaching the light receiving element changes. Then, the pulse rate (pulse rate per unit time) can be measured by analyzing the temporal change of the light amount detected by the light receiving element, that is, the pulse wave.
In the present embodiment, the biological information detection unit 41 that detects a pulse wave is configured to include the photoelectric sensor. For example, an ultrasonic wave that detects the contraction of a blood vessel using ultrasonic waves and measures the pulse rate. It may be configured to have a sensor, or may be configured to include a sensor, a piezoelectric element, or the like that detects a pulse by flowing a weak current from the electrode into the body.

The acceleration detection unit 42 includes an acceleration sensor that detects an acceleration value (acceleration data) associated with the operation of the user wearing the measuring device 1, and outputs the detected acceleration value to the control unit 8. An example of such an acceleration sensor is a three-axis sensor that detects acceleration values on the X-axis, Y-axis, and Z-axis at a predetermined sampling frequency (for example, 16 Hz).
For example, the acceleration detection unit 42 detects the movement of the user, and the detected acceleration signal is amplified, shaped, and A / D converted by an amplification circuit, a waveform shaping circuit, and an A / D conversion circuit (all not shown). Output as acceleration data (acceleration value). The acceleration data for the three axes is stored (stored) in the storage unit 7 along the time series as an acceleration data string. The acceleration data stored in this way is used for behavior analysis of the user (wearer), as will be described in detail later.

[Configuration of charging means]
The charging means 5 is constituted by a charging circuit, and charges the secondary battery with power supplied from the cradle (not shown) via a terminal (not shown) exposed outside the case 2. The charging unit 5 includes a supply detection unit 51 that detects a voltage supplied to the terminal, and the charging unit 5 sends a notification signal for notifying the presence or absence of external power supply to the control unit 8 described later. Output. For this reason, the control means 8 can determine whether or not the power supply to the measuring apparatus 1 is performed based on the notification signal, that is, whether or not the measuring apparatus 1 and the cradle are connected.

[Configuration of communication means]
The communication unit 6 is a module that communicates with the external device 200 (see FIG. 1) under the control of the communication control unit 84 described later. In the present embodiment, the communication means 6 is configured by a module (for example, a module that complies with a short-range wireless communication standard such as IEEE 802.15 standard) that communicates with the external device 200 wirelessly. May be adopted. Such communication means 6 corresponds to a transmission unit of the present invention.

[Configuration of storage means]
The storage means 7 stores a program and data necessary for the operation of the measuring apparatus 1, and corresponds to a storage unit of the present invention. As such a program, the storage unit 7 stores a transmission control program that causes the control unit 8 to execute a transmission control process for transmitting transmission information including the behavior information. This transmission control process will be described in detail later.
As the data, the storage unit 7 stores connection information for communication connection with the external device 200 via the communication unit 6. Further, the storage unit 7 stores the detection result by the behavior detection unit 4 under the control of the control unit 8, and also stores the propriety of transmission based on the transmission result of transmission information performed in the past. Such a storage means 7 can be composed of a nonvolatile semiconductor memory such as a flash memory.

[Configuration of control means]
FIG. 4 is a block diagram showing the configuration of the control means 8.
The control means 8 is composed of a control circuit and controls the operation of the measuring apparatus 1. That is, the control means 8 autonomously controls the operation of the measuring device 1. In addition, the control unit 8 executes a transmission control process for transmitting transmission information including the behavior information detected by the behavior detection unit 4 to the external device 200.
As shown in FIG. 4, when the control circuit 8 executes the program stored in the storage unit 7, the control unit 8 includes a timer unit 81, an operation control unit 82, a notification control unit 83, and a communication control unit. 84, each of the function units functioning as a transmission time determination unit 85, an analysis unit 86, a transmission availability determination unit 87, a transmission control unit 88, a transmission success / failure determination unit 89, and a transmission result recording unit 90.

The timer 81 measures the current date and time.
The operation control unit 82 controls the operation of the entire device. For example, the operation control unit 82 analyzes the pulse wave detected by the biological information detection unit 41 to measure the pulse rate (pulse rate per unit time), and stores the pulse rate in the storage unit 7. In addition, the acceleration data detected by the acceleration detector 42 is stored in the storage unit 7. Further, the operation control unit 82 determines the operation content of the user based on the acceleration change pattern detected by the acceleration detection unit 42, and executes processing according to the operation content. For example, the operation control unit 82 determines that the tap operation has been performed when the change in the acceleration value according to the continuous impact caused by the tap operation on the measuring device 1 occurs, and executes the process according to the operation mode. .

The notification control unit 83 controls the display unit 31 to display the operation state of the measuring apparatus 1 and the number of taps. In addition, the notification control unit 83 controls the vibration unit 32 to vibrate the measurement apparatus 1.
The communication control unit 84 communicates with the external device 200 via the communication unit 6 when the measuring apparatus 1 can communicate with the external device 200. At this time, the communication control unit 84 communicates with the external device 200 associated with the measurement apparatus 1 based on the connection information stored in the storage unit 7.

The transmission time determination unit 85 determines whether it is time to transmit information to the external device 200. Such timing is stored in the storage unit 7 in advance, and is set, for example, so that the timing comes every minute. Further, the transmission time determination unit 85 may determine that the transmission timing is reached when a predetermined amount of data (for example, 100 packets, 1000 packets, etc.) is reached.
Based on the behavior information including the pulse rate and acceleration data as the biological information detected by the biological information detection unit 41 and the acceleration detection unit 42 and stored in the storage unit 7, the analysis unit 86 determines the type of the user's behavior. Analyze the action type.
Here, examples of the action type include walking, running, mild housework, sitting, and resting.

The transmission availability determination unit 87 determines whether transmission information including the behavior information can be transmitted to the external device 200.
Here, as described above, the storage means 7 indicates whether or not the transmission of the transmission information performed in the past is successful or unsuccessful depending on whether or not the transmission information is transmitted. Stored for each action type. That is, depending on the type of action performed by the user, there is a high possibility of failure even if information is transmitted by the communication means 6. For this reason, with respect to an action type having a high probability of failing in information transmission, transmission permission / prohibition based on a past transmission result is stored for each action type in order to restrict transmission in advance.
The transmission permission / inhibition determination unit 87 stores the user action type analyzed by the analysis unit 86, that is, the current user action type and the storage unit 7, and transmits the action according to the action type. Whether or not information transmission to the external device 200 is possible is determined based on whether or not it is possible.
Note that the determination of whether to transmit information by the transmission permission determination unit 87 is not limited to this. For example, it is possible to store in advance whether or not transmission is possible for each action type in the storage unit 7, and the transmission availability may not reflect a transmission result corresponding to the user's action. That is, the transmission permission / prohibition may be configured not to be updated.

  The transmission control unit 88 determines that the information transmission to the external device 200 is possible by the transmission permission / non-permission determination unit 87, and further determines that communication with the external device 200 is possible by the communication control unit 84. By means 6, transmission information including the behavior information is transmitted to the external device 200. At this time, the transmission control unit 88 causes the communication unit 6 to transmit the behavior information stored in the storage unit 7 during the period from the successful transmission processing of the transmission information to the present. On the other hand, when it is determined that information transmission to the external device 200 is not possible, the transmission control unit 88 regulates transmission of the transmission information by the communication unit 6.

The transmission success / failure determination unit 89 determines whether transmission information transmission to the external device 200 by the communication unit 6 is successful.
When the transmission success / failure determination unit 89 determines that the transmission information has been successfully transmitted, the transmission result recording unit 90 receives information transmitted by the communication unit 6 among the transmission results for each action type stored in the storage unit 7. The success count of the transmission result corresponding to the user's action type when it is performed is incremented by one.
On the other hand, when the transmission success / failure determination unit 89 determines that transmission of transmission information has failed, the transmission result recording unit 90 is similarly stored in the storage unit 7 and also includes a transmission result corresponding to the user's action type. Increase the number of failures by one.
Then, the transmission result recording unit 90 updates the success / failure of the corresponding action type based on the updated number of successes and failures.

[Information transmission process]
FIG. 5 is a flowchart showing information transmission processing executed by the control means 8.
When the measuring device 1 is attached to the user, the control unit 8 executes the following information transmission process based on the program stored in the storage unit 7.
In this information transmission process, as shown in FIG. 5, first, the operation control unit 82 operates the behavior detection unit 4 and is used by the biological information detection unit 41 and the acceleration detection unit 42 that constitute the behavior detection unit 4. The biological information and acceleration value of the person are detected (steps S11 and S12). The detected biological information and acceleration value are stored in the storage unit 7 as described above.

Thereafter, the transmission time determination unit 85 determines whether or not it is time to transmit the behavior information stored in the storage unit 7 (step S13).
Here, if it is determined that the timing is not reached, the control means 8 returns the process to step S11. That is, in the measuring apparatus 1, action information is continuously detected and stored in the storage unit 7.
On the other hand, if it is determined that the timing has come, the control means 8 executes the transmission control process S14, and after the transmission control process S14 ends, the process returns to step S11.

[Transmission control processing]
FIG. 6 is a flowchart showing the transmission control process.
In the transmission control process S14, as shown in FIG. 6, the analysis unit 86 analyzes the type of action (action type) of the current user based on the action information stored in the storage unit 7 (step S141). ).
Thereafter, the transmission permission / inhibition determination unit 87 determines whether or not information can be transmitted to the external device 200 (step S142).
When it is determined in the determination process of step S142 that information transmission to the external device 200 is not possible with the current user action type, the transmission control unit 88 transmits transmission information including action information by the communication unit 6. Are restricted (step S143). For this reason, the action information continues to be stored in the storage unit 7.
After step S143, the control means 8 ends the transmission control process S14, and returns the process to step S11 as shown in FIG.

On the other hand, if it is determined by the determination processing in step S142 that the current user's action type is an action type that allows information transmission to the external device 200, the communication control unit 84 communicates with the external device 200. It is determined whether or not it is possible (step S144).
If it is determined that communication with the external device 200 is not possible, the control unit 8 shifts the process to step S143 and executes the process.
On the other hand, when it is determined that communication with the external device 200 is possible, the transmission control unit 88 transmits the transmission information including the behavior information stored in the storage unit 7 to the external device 200 by the communication unit 6 (step S145). ).

Next, the transmission success / failure determination unit 89 determines whether or not the transmission process of step S145 has been successful (step S146).
Here, if it is determined that the transmission process is successful, the transmission result recording unit 90 increments the number of successes of the corresponding transmission result by one, and based on the updated number of successes and the number of failures, the corresponding action type Whether transmission is possible is updated (step S147).
On the other hand, if it is determined that the transmission process has failed, the transmission result recording unit 90 increments the number of failures of the corresponding transmission result by one, and transmits the corresponding action type based on the updated number of successes and the number of failures. The availability is updated (step S148).
After these steps S147 and S148, the control means 8 ends the transmission control process S14.

[Effect of the first embodiment]
The biological information measuring apparatus 1 according to the present embodiment described above has the following effects.
Transmission information (biological information) based on the action type of the wearer analyzed based on the biological information and acceleration data detected by the measuring apparatus 1 and the availability of transmission corresponding to the action type stored in the storage means 7. When it is determined that information and acceleration data) can be transmitted, the transmission information is transmitted by the communication unit 6. According to this, the wearer can transmit the transmission information without performing any operation.
Further, when the analyzed action type of the wearer is an action type that cannot transmit the transmission information, the transmission of the action information can be restricted, so that it is possible to suppress the power consumption due to the execution of the useless transmission process. Therefore, transmission information can be efficiently transmitted to the external device 200.

  The transmission result recording unit 90 stores in the storage unit 7 whether transmission is possible based on the transmission result of the transmission information by the communication unit 6 for each action type, and the transmission availability determination unit 87 corresponds to the analyzed action type of the wearer. It is determined whether or not transmission information can be transmitted based on whether or not the action type can be transmitted. That is, the transmission permission / inhibition determination unit 87 determines whether or not transmission information can be transmitted based on a transmission result corresponding to an action actually performed by the wearer. As a result, it is possible to determine whether or not transmission is possible in accordance with the actual use situation of the wearer. That is, since it can be determined more appropriately whether transmission information can be transmitted, execution of useless transmission processing can be suppressed. Therefore, power consumption can be reduced and the driving time of the measuring apparatus 1 can be extended.

The behavior detection unit 4 includes a biological information detection unit 41 that detects biological information, and an acceleration detection unit 42 that detects an acceleration value (acceleration data) acting on the wearer. Thereby, based on the biometric information and acceleration data detected by each detection part 41 and 42, the action classification of a wearer's action can be determined appropriately.
Moreover, since at least the biological information is included in the transmission information, the biological information can be reliably managed by the external device 200 that receives the transmission information.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The biological information measurement system according to the present embodiment has the same configuration as the biological information measurement system MS described above, and the biological information measurement device uses the transmission information based on the information amount (data amount) of the transmission information. It has a function of determining whether transmission is possible. In this respect, the biological information measuring system according to the present embodiment is different from the biological information measuring system MS. In the following description, parts that are the same as or substantially the same as those already described are given the same reference numerals and description thereof is omitted.

FIG. 7 is a block diagram showing the configuration of the control means 8A included in the measuring apparatus 1A according to the present embodiment.
The measurement apparatus 1A according to the present embodiment has the same configuration and function as the measurement apparatus 1 except that the control means 8A is provided instead of the control means 8.
The control unit 8A has the same configuration and function as the control unit 8 except that the control unit 8A includes an information amount acquisition unit 91, an information amount determination unit 92, and a transmission rate change unit 93.

The information amount acquisition unit 91 functions when the transmission time determination unit 85 determines that the timing is reached. The information amount acquisition unit 91 acquires the information amount of the transmission information including the action information stored in the storage unit 7.
Based on the information amount of the transmission information acquired by the information amount acquisition unit 91, the information amount determination unit 92 transmits the transmission information to the external device 200 according to the user action type analyzed and specified by the analysis unit 86. Determine if you can. When the information amount determination unit 92 determines that transmission is not possible, the transmission control unit 88 restricts transmission of transmission information by the communication unit 6 and suppresses unnecessary power consumption.

  The transmission rate changing unit 93 functions when the transmission success / failure determining unit 89 determines that information transmission has failed. The transmission rate changing unit 93 changes the transmission rate when transmitting transmission information to the external device 200. Specifically, when it is determined that the information transmission has failed, the transmission rate changing unit 93 increases the transmission rate, and at the next information transmission, more information is accumulated and the amount of information is larger than the previous time. The transmission information thus obtained can be reliably transmitted within the communicable period with the external device 200. Further, when it is determined that the information transmission has been successful and the transmission rate has been changed, the transmission rate changing unit 93 returns the changed transmission rate to the original transmission rate. Thereby, the operation frequency (operating rate) of the control means 8A is reduced, and the power consumption is reduced.

Note that the change in transmission rate refers to a change in the transmission speed of information to the external device 200 or a change in transmission format. For example, when the transmission information is transmitted after being divided into a plurality of packets, the former includes changing the transmission speed of each packet, and the latter includes information on each packet without changing the transmission frequency. It is possible to change the amount.
In the present embodiment, the transmission rate changing unit 93 changes the transmission speed to double when it is determined that the information transmission has failed.

FIG. 8 is a flowchart showing a transmission control process in the present embodiment.
The control means 8A executes the following transmission control process instead of the transmission control process S14 in the biological information transmission process.
In this transmission control process, as shown in FIG. 8, the analysis unit 86 analyzes the current user behavior type (behavior type) based on the behavior information stored in the storage unit 7 (step S <b> 141). ). Thereafter, the information amount acquisition unit 91 detects the data amount (information amount) of the biological information and acceleration data (transmission information) stored in the storage unit 7 (step S151).
Thereafter, the control means 8 determines whether or not transmission information can be transmitted to the external device 200 (step S152).
If it is determined in the determination process in step S152 that information cannot be transmitted to the external device 200 by the current user action type or cannot be transmitted by the information amount determination unit 92, the transmission control unit 88 performs communication. Transmission of transmission information including action information by means 6 is restricted (step S143). For this reason, the action information continues to be stored in the storage unit 7.

On the other hand, if it is determined by the determination processing in step S152 that the current user's action type is an action type capable of transmitting information to the external device 200, the communication control unit 84 performs communication with the external device 200. It is determined whether or not it is possible (step S144).
If it is determined that communication with the external device 200 is not possible, the control unit 8 shifts the process to step S143 and executes the process.
On the other hand, when it is determined that communication with the external device 200 is possible, the transmission control unit 88 transmits the transmission information including the behavior information stored in the storage unit 7 to the external device 200 by the communication unit 6 (step S145). ). If the transmission rate is changed by the transmission rate changing unit 93 in step S154 described later, the transmission control unit 88 maintains the changed transmission rate as a transmission rate suitable for the current action type. The transmission information (biological information) is transmitted to the external device 200 at the transmission rate.

Next, the transmission success / failure determination unit 89 determines whether or not the transmission process of step S145 has been successful (step S146).
Here, when it is determined that the transmission process has failed, the transmission result recording unit 90 increments the number of failures of the corresponding transmission result by one, and transmits the corresponding action type based on the updated number of successes and the number of failures. The availability is updated (step S148). Then, the transmission rate changing unit 93 doubles the transmission speed of the transmission information (step S154).
On the other hand, if it is determined that the transmission process is successful, the transmission result recording unit 90 increments the number of successes of the corresponding transmission result by one, and the success or failure of the corresponding action type is determined based on the updated number of successes and failures. Is updated (step S147). And the transmission rate change part 93 returns the transmission speed of transmission information to the transmission speed before change (step S155).
After these steps S154 and S155, the control means 8A ends the transmission control process.

[Effects of Second Embodiment]
The biological information measuring device of the second embodiment has the following effects in addition to the same effects as the biological information measuring device 1 of the first embodiment.
According to the biological information measuring apparatus 1A, it is determined that the information amount of the transmission information acquired by the information amount acquisition unit 91 is not the information amount that can be transmitted with respect to the wearer's action type analyzed by the information amount determination unit 92. In such a case, the transmission control unit 88 regulates transmission of transmission information. As a result, it is possible to suppress transmission processing that is likely to end in failure. Therefore, since it is possible to reliably suppress the execution of useless transmission processing, it is possible to reduce power consumption and, in turn, extend the driving time of the biological information measuring device 1A.

  When the transmission success / failure determination unit 89 determines that transmission of transmission information has failed, the transmission rate changing unit 93 changes the transmission speed of the transmission information. Thereby, by increasing the transmission speed, the transmission time can be reduced as compared with the transmission processing at the normal transmission speed. Therefore, the possibility that transmission information can be transmitted can be increased, and the number of useless transmission processes can be reduced. Therefore, power consumption can be reduced.

  When the transmission information is successfully transmitted in a state where the transmission speed is changed, the transmission speed is returned to the transmission speed before the change. Thereby, it can suppress that the transmission process of the said transmission information is always performed with the changed transmission speed with high power consumption. Therefore, a useless increase in power consumption can be suppressed.

[Modification of Embodiment]
The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
In each of the above embodiments, the biological information detected by the biological information detection unit 41 may not be a pulse wave and a pulse rate. For example, other biological information such as an electroencephalogram and a heart rate may be used.
Moreover, although the measuring apparatus 1 and 1A are comprised by the wristwatch type and the mounting site | part of the said measuring apparatus 1 and 1A was the wearer's wrist 410, this invention is not limited to this. For example, it may be attached to the ankle, chest and abdomen.

In the above embodiments, the action type analyzed by the analysis unit 86 is not limited to the above type. For example, the behavior of the wearer classified as exercise may be analyzed in more detail according to the type of exercise, such as cycling or climbing.
Moreover, although the transmission information transmitted by the communication means 6 from the measuring apparatuses 1 and 1A includes biological information and acceleration data, the present invention is not limited to this. For example, when the external device 200 manages only the wearer's biological information, transmission information including at least the biological information may be transmitted to the external device 200.

In the above embodiments, the external device 200 stores and displays the calorie consumption of the user calculated based on the received behavior information. However, the present invention is not limited to this. For example, the user's action type may be displayed.
Further, the calorie consumption of the user may not be calculated in the external device 200. For example, a calculation unit may be provided in the measurement devices 1 and 1A, and the measurement devices 1 and 1A may calculate calorie consumption and transmit the calculated calorie consumption to the external device 200.

  In each of the above embodiments, a triaxial acceleration sensor is used as the acceleration sensor provided in the acceleration detection unit 42. However, the present invention is not limited to this. For example, the acceleration sensor may be at least a biaxial acceleration sensor. For example, the acceleration detection unit 42 may include a biaxial acceleration sensor that is substantially orthogonal, or may include a four-axis or more acceleration sensor that intersects three-dimensionally. Further, the acceleration value detected by the acceleration detection unit 42 may be used for a process of reducing noise caused by body motion superimposed on the pulse wave signal detected by the biological information detection unit 41 which is a pulse wave detection unit. Good.

  In each said embodiment, the detection of the biometric information and the detection of acceleration data in step S11 and step S12 are not restricted to the said order. For example, detection of biological information and acceleration data may be started simultaneously, and the detection order may be reversed. That is, as long as biometric information and acceleration data are continuously detected and stored in the storage unit 7, step S11 and step S12 may be performed in any order.

  In the second embodiment, the determination by the information amount determination unit 92 may not be performed based on the information amount of the transmission information acquired by the information amount acquisition unit 91. That is, the information amount acquisition unit 91 and the information amount determination unit 92 may not be provided.

  In the said 2nd Embodiment, when it determines with transmission of the biometric information of step S146 having failed, you may vibrate the vibration part 32 under control of the alerting | reporting control part 83. FIG. According to this, since the user can recognize that the transmission of the biological information has failed, for example, an action (for example, a resting state) in which the transmission of the biological information is likely to be successful is performed for the next transmission of the biological information. be able to.

  In step S154 of the second embodiment, when it is determined that the information transmission has failed, the transmission rate changing unit 93 changes the transmission speed to double. However, the present invention is not limited to this. For example, the transmission speed may be changed to 4 times or 8 times. That is, the transmission speed to be changed only needs to be higher than the transmission speed before the change.

In step S154 of the second embodiment, after changing the transmission rate, information transmission is restricted in step S143 and the process is terminated. However, the present invention is not limited to this. For example, after step S143, the process may be returned to step S141.
Moreover, after changing a transmission rate in step S154, it transfers to the process of step S145 and it is good also as transmitting biometric information with the changed transmission rate again. According to this, since the transmission information is transmitted immediately after the transmission of the biological information is unsuccessful, the external device 200 can confirm the transmission information (biological information) at an early stage. In addition, when returning to the process of step S145 after step S154, when transmission of transmission information fails a predetermined number of times (for example, twice) by the determination of the transmission success / failure determination unit 89 in step S153, the process returns to step S141. do it. Thereby, the number of useless transmission processes can be reduced.

  When executing step S154 of the second embodiment, the transmission rate is changed by the transmission rate changing unit 93, but the transmission rate may not be changed. For example, the cycle of the transmission timing determined by the transmission time determination unit 85 may be shortened, and in addition to this, the transmission rate may be changed.

  When executing step S154 of the second embodiment, it is determined whether or not it is the same as the action type at the time of the previous transmission, and if it is the same, the transmission rate changing unit 93 is the same in step S154. If the transmission rate is changed by the transmission control unit 88, the transmission control unit 88 maintains the changed transmission rate as a transmission rate suitable for the current action type, and transmits the transmission information (biological information) according to the transmission rate. It is good also as a structure which transmits to the apparatus 200. FIG.

  In the second embodiment, when transmission of transmission information is successful, in step S154, the transmission rate changed by the transmission rate changing unit 93 is returned to the transmission rate before the change in step S155. However, the present invention is not limited to this. The transmission rate after the change is stored in the storage unit 7 as a transmission rate suitable for the action type, and the transmission rate according to the action type of the user when it is determined as the transmission timing is acquired from the storage unit 7, The transmission information may be transmitted at a transmission rate. According to such a configuration, transmission information (biological information) is transmitted at a transmission rate suitable for the action type, so that the number of useless transmission processes can be reduced.
