Description

  The present invention relates to a biometric apparatus that generates biometric information such as the weight of a measurement target (typically a user).

  Many biological measuring apparatuses such as a weight scale and a body fat scale are driven by a battery. For this reason, in order to reduce power consumption, some have an automatic off function for shifting from a use state to a standby state when there is no input operation or the like. In the biometric device described in Patent Document 1, a reference time for determining automatic off is determined in advance, and when the state where there is no measurement or operation reaches the reference time or more, the power of the device is automatically shut off. Yes.

  In addition, it has a function of detecting with a sensor that a load has been applied to a biometric apparatus in a standby state, and turning on the apparatus based on the detection result to shift to a use state in which biometric information can be measured. A so-called step-on type biometric apparatus has been proposed. As an example, when a person gets on, the mechanical switch mechanism is turned on by the load, so that the device is shifted from the standby state to the use state (see Patent Document 2), and the output of the load cell is set at a short time interval. Obtaining and continuously monitoring whether or not an output that can be evaluated as a person has been detected is detected, and when such an output is detected, there is one that shifts the biometric device from a standby state to a use state.

By the way, the biometric device is generally used for managing personal health at home and installed in a living room or kitchen. If such a widely used biometric measuring device can be used for security management during absence or the activity of a single family member, convenience can be improved.
However, some conventional biometric devices are equipped with a step-on function, but there are no functions for security management while the user is away or the activity of a family living alone.

Further, according to this embodiment, further, since also serves as a detector for use in discriminating the standby state and the use state in the first mode to the detection of biological approaches in the second mode, simplify the configuration of the biometric device can do.
The first distance may be equal to or less than the second distance. The first distance needs to be set to a relatively short distance so that the user is more likely to place and measure on the biometric device. On the other hand, intruders are preferably detected as widely as possible. According to this aspect, since the first distance is equal to or less than the second distance, the signal generator is operated only when the user is highly likely to measure while detecting that the living body is approaching in a wide range. Is possible.

Another aspect of the biometric apparatus according to the present invention is a biometric apparatus that measures biometric information indicating a user's biological state, and a detection unit that outputs a detection signal having a magnitude corresponding to the distance from the living body.

In this case, the alarm unit may be controlled to cancel the alarm.

  According to this aspect, the alarm can be stopped using the characteristics of the user's living body. Therefore, even if the intruder operates the biometric device to stop the alarm, the alarm is continued, so that the intruder can be surely urged to leave. Here, when the control unit controls the alarm unit to cancel the alarm, the control unit may shift from the second mode to the first mode.

The alarm unit may be controlled so as to cancel the alarm when they match.

  According to this aspect, the alarm can be stopped using the identification information of the external device. Therefore, even if the intruder operates the biometric device to stop the alarm, the alarm is continued, so that the intruder can be surely urged to leave. Here, the external device may be, for example, a terminal device or a portable biometric device such as an activity meter. In addition, when the control unit controls the alarm unit to cancel the alarm, the control unit may shift from the second mode to the first mode.

In one aspect of the biometric device described above, when the control unit detects an intruder in the second mode, the control unit generates warning information and controls the communication unit to transmit the warning information to the outside. If the warning information is not transmitted to the outside at the time when the alarm unit is controlled to cancel the alarm, the transmission of the warning information may be canceled.
According to this aspect, if the warning is canceled before the warning information is transmitted, the transmission of the warning information can be stopped. For example, if the user accidentally approaches the biometric device after setting to the second mode, warning information is generated, but if the warning information is not transmitted, transmission can be canceled. , It is possible to prevent the user from receiving meaningless warning information.
In addition, the control unit may control the communication unit to transmit confirmation information indicating that the alarm has been released to the outside after controlling the alarm unit to release the alarm.

The biometric apparatus 100 of the present embodiment is driven by a battery (not shown) inserted into the biometric apparatus 100, but is not limited thereto. The control unit 20 controls each element of the biometric apparatus 100 by executing a program stored in the storage unit 22. The control unit 20 generates the user's body weight (weight) MA and the body composition index MB as the biological information M. The body composition index MB is an index related to the body composition of the user, and corresponds to, for example, body fat percentage, muscle mass, body moisture percentage, BMI (Body Mass Index), and the like. The storage unit 22 is a means (for example, a non-volatile memory) for storing the user's biological information M for each user in addition to the program executed by the control unit 20 and various data used by the control unit 20. .

  The display unit 24 (for example, a liquid crystal display panel) in FIG. 2 is installed in an opening formed in the measurement table 122 as illustrated in FIG. 1 and displays various images under the control of the control unit 20. . For example, the measurement result (biological information M) of the user and a mode to be described later are displayed on the display unit 24. The alarm unit 26 issues an alarm to the intruder. For example, the alarm unit 26 includes a speaker and an amplifier, and emits a signal amplified by the amplifier at a high volume from the speaker. The alarm unit 26 may also serve as a notification unit that performs voice guidance in the first mode. In this case, the notification unit performs voice guidance such as “Measurement preparation is completed” and “Weight is 60 k”. The operation unit 28 is an input device that receives an instruction from a user, and includes a plurality of operators installed on the measurement table 122 as illustrated in FIG. The operation unit 28 includes, for example, a power button for turning on / off the power, a display switching button for switching display on the display unit, a memory button for storing a user, a function button for selecting various functions, A setting button for making various settings, a decision button for making a decision when setting or selecting a function, and the like are included, but the invention is not limited to these. Note that a touch panel configured integrally with the display unit 24 can be used as the operation unit 28.

  2 generates a measurement signal D (DA, DB) corresponding to the weight or body composition of the user. The signal generation unit 30 includes a weight detection unit 32 and a body composition detection unit 34. The weight detection unit 32 generates a measurement signal DA corresponding to the load acting on the measurement table 122. As shown in FIG. 2, the weight detection unit 32 includes a detection body 322 and an amplifier 324. The detection body 322 generates a voltage corresponding to the load acting on the measurement table 122. Specifically, a strain gauge that generates a voltage (that is, a voltage according to the weight of the user on the measurement table 122) according to deformation of the strain body disposed below the measurement table 122 is a detection body 322. Can be used as The amplifier 324 amplifies the voltage generated by the detector 322 and generates the measurement signal DA. The measurement signal DA is converted into a digital signal by an A / D converter (not shown) and then input to the control unit 20.

  The detection unit 40 generates a detection signal DC having a magnitude corresponding to the distance between the living body and the detection unit 40. Although the case where an infrared sensor is used as the detection part 40 is demonstrated in FIG.1 and FIG.2, it may be an ultrasonic type sensor using an ultrasonic wave, for example, and is not specifically limited. In addition, since the illuminance on the measurement table 122 of the biometric device 100 changes depending on whether the user approaches or separates from the biometric device 100, an illuminance sensor that can output a detection signal DC corresponding to the illuminance. Can also be used in the detection unit 40. In the present embodiment, the configuration in which the measurement processing unit 52 determines the proximity of the living body based on the detection signal DC of the detection unit 40 will be described. However, it goes without saying that a human sensor that can determine the proximity of the living body may be used. Yes.

  As shown in FIGS. 1 and 2, the detection unit 40 includes, as an example, an irradiation unit 41 that emits infrared rays and a light receiving unit 42 that receives reflected infrared rays. The irradiation unit 41 emits a predetermined amount of infrared rays in accordance with an instruction signal from the control unit 20. The light receiving unit 42 detects infrared light reflected by an object or the like around the biometric device 100 and outputs a detection signal DC corresponding to the detected magnitude of the infrared light to the measurement processing unit 52. The measurement processing unit 52 determines the proximity of the user to the biometric device 100 based on the detection signal DC from the light receiving unit 42. For example, the measurement processing unit 52 determines that a person is in proximity to the biometric device 100 when the detection signal DC from the light receiving unit 42 is larger than a predetermined dark value. If the difference between the output values of the detection signal DC acquired from the light receiving unit 42 at the current determination and the detection signal DC acquired from the light receiving unit 42 at the previous determination is greater than a predetermined dark value, You may make it determine with a person approaching the measuring apparatus 100, and the determination method is not specifically limited.

  In the biometric apparatus 100, the range detected by the detection unit 40 is appropriately set according to the installation positions of the irradiation unit 41 and the light receiving unit 42, the angle range / intensity of infrared rays irradiated by the irradiation unit 41, and other conditions. Two or more irradiating units and light receiving units may be provided or may not be the same number. Further, the infrared sensor is not necessarily limited to the infrared sensor provided with the irradiating unit, and the infrared sensor that can detect the infrared ray and output the detection signal DC may detect the infrared ray emitted by the person as thermal energy. .

  Next, the body composition detection unit 34 generates a measurement signal DB corresponding to the body composition of the user. As shown in FIG. 2, the body composition detection unit 34 includes a current supply unit 342, a voltage measurement unit 344, a pair of current supply electrodes 346, and a pair of voltage measurement electrodes 348. As illustrated in FIG. 1, each current supply electrode 346 and each voltage measurement electrode 348 are installed on the surface of the measurement table 122 so as to contact the right foot and the left foot of the user on the measurement table 122. The current supply unit 342 supplies a measurement current between the pair of current supply electrodes 346. The measurement current is an alternating current having a predetermined frequency (for example, 5 kHz to 250 kHz) flowing between the current supply electrodes 346 via the user's body. The voltage measurement unit 344 generates a measurement signal DB corresponding to the voltage between the pair of voltage measurement electrodes 348. The measurement signal DB is a signal corresponding to the body composition (bioimpedance) of the user, converted into a digital signal by an A / D converter (not shown), and then input to the control unit 20.

  As shown in FIG. 2, the control unit 20 executes a program stored in the storage unit 22 to generate a plurality of elements (measurement processing unit 52, communication control unit 54, mode setting) for generating the biological information M. Unit 55 and display control unit 56). A configuration in which each function of the control unit 20 is distributed to a plurality of devices or a configuration in which a part of the function of the control unit 20 is realized by a dedicated electronic circuit (for example, a DSP) may be employed.

  The measurement processing unit 52 generates the biological information M corresponding to the measurement signal D (DA, DB) generated by the signal generation unit 30. Specifically, the measurement processing unit 52 calculates the weight MA of the user according to the measurement signal DA generated by the weight detection unit 32, and the user's weight according to the measurement signal DB generated by the body composition detection unit 34. Calculate body composition index MB. The communication control unit 54 controls communication with the terminal device 14 via the communication unit 29. The display control unit 56 displays various images on the display unit 24.

  Next, the mode setting unit 55 sets the first mode and the second mode (detection mode / watching mode) based on the operation signal output from the operation unit 28 according to the user's operation. In this example, the first mode is set as the initial state.

  First, the operation in the first mode will be described. As described above, the first mode is a mode for generating the biological information M. In the first mode, the control unit 20 compares the detection signal DC with the first threshold value ref1. The first threshold value ref1 corresponds to the case where the distance between the living body and the detection unit 40 (light receiving unit 42) is the first distance L1. Therefore, the control unit 20 determines whether the distance from the living body is equal to or less than the first distance L1 based on the detection signal DC. When the determination result is equal to or less than the first distance L1, the control unit 20 sets the use state in which the signal generation unit 30 is operated, and controls the signal generation unit 30 to supply power. On the other hand, when the determination result exceeds the first distance L <b> 1, the standby state in which the operation of the signal generation unit 30 is stopped is set, and the control unit 20 performs control so that power is not supplied to the signal generation unit 30. As a result, as shown in FIG. 3, when the user approaches within the distance L1 (within the dotted line in the drawing) from the light receiving unit 42 of the biometric device 100, the control unit 20 is set to the use state and used from that range. When the person leaves, the control unit 20 sets the standby state.

  By the way, if there is a user at the boundary of the dotted line shown in FIG. 3 and repeats entering and exiting the dotted line, the use state and the standby state are frequently switched. Thus, when the standby state is shifted to the use state, the use state may be continued as long as a predetermined time has not elapsed. FIG. 4 is a flowchart showing the operation of the control unit that gives temporal hysteresis characteristics to the transition between the use state and the standby state.

  First, the control unit 20 determines whether or not the detection signal DC is equal to or less than the first threshold value ref1 (S1). If this determination condition is denied, the living body does not exist within the first distance L1, and the control unit 20 sets the standby state (S2), stops the operation of the signal generation unit 30, and performs the processing. Return to step S1.

And if the determination conditions of step S1 are affirmed, the control part 20 will be set to a use state (S3), and will make the time measuring part 21 start time measurement (S4). Thereafter, the control unit 20 determines whether or not the time T counted by the time measuring unit 21 is equal to or longer than the reference time Tref (S5), and repeats the determination process until Tref ≦ T. When the time T becomes equal to or greater than the reference time Tref, the process returns to step S1 to determine whether or not the detection signal DC is equal to or less than the first threshold value ref1.
Therefore, when shifting from the standby state to the use state, the use state can be continued for at least the reference time Tref, and frequent switching between the use state and the standby state can be prevented.

  Next, FIG. 5 is a flowchart showing the operation of the control unit 20 in the use state. When shifting from the standby state to the use state, the measurement processing unit 52 of the control unit 20 sets the zero point weight W0 corresponding to the measurement signal DA generated by the weight detection unit 32 (S11). The zero point weight W0 is a weight value (reference value) serving as a reference (zero point) of the weight of the user. The zero point weight W 0 generated by the measurement processing unit 52 is stored in the storage unit 22. When the setting of the zero weight W0 is completed, the display control unit 56 causes the display unit 24 to display the measurement start image G1 of FIG. 6 informing the user that the state has been changed to a measurable state (S12).

  When the measurement start image G 1 displayed on the display unit 24 is confirmed, the user is placed on the measurement table 122. The measurement processing unit 52 generates the biological information M of the user on the measurement table 122 according to the measurement signal D (DA, DB) generated by the signal generation unit 30 (S13). Specifically, the measurement processing unit 52 calculates the weight (weight) MA of the user by subtracting the zero point weight W0 from the weight corresponding to the measurement signal DA generated by the weight detection unit 32. That is, the user's weight MA based on the zero point weight W0 is calculated. Further, the measurement processing unit 52 calculates the body composition index MB (body fat percentage) of the user from the measurement signal DB generated by the body composition detection unit 34. Specifically, the measurement processing unit 52 calculates the bioimpedance of the user according to the relationship between the measurement signal DB and the measurement current, and the biometric basic information B that is input to the biometric device 100 by the user in advance. The body composition index MB is calculated according to (for example, age, sex, height, etc.). A known technique can be arbitrarily employed for calculating the body composition index MB. For example, the body composition index is obtained by applying the measured value of the bioimpedance to the regression formula selected according to the basic biometric information B among a plurality of types of regression formulas expressing the statistical correlation between the bioimpedance and the body composition index MB. It is possible to calculate MB.

  When the biological information M is generated by the above procedure, the display control unit 56 causes the display unit 24 to display the measurement result image G2 of FIG. 7 that notifies the user of the biological information M calculated by the measurement processing unit 52 ( S14). As illustrated in FIG. 6, the measurement result image G2 includes a body weight MA and a body composition index (body fat percentage in the example of FIG. 7) MB. In this way, the biological information M can be generated in the usage state.

  Next, the detection mode belonging to the second mode will be described. As described above, the detection mode is a mode for detecting an intruder. For example, the detection mode is used when the user is away from home. In the second mode, the control unit 20 maintains the standby state and does not shift from the standby state to the use state. This is because the detection mode is used for detecting an intruder, and thus there is no need to measure the biological information M.

  FIG. 8 is a flowchart showing the operation of the control unit 20 in the detection mode. First, the control unit 20 compares the detection signal DC with the second threshold value ref2, and determines whether or not the detection signal DC is greater than or equal to the second threshold value ref2 (S21). The second threshold value ref2 corresponds to the case where the distance between the living body and the detection unit 40 is the second distance L2. Here, the second distance L2 may be greater than or equal to the first distance L1. Since the first distance L1 is shifted from the standby state to the use state, the first distance L1 should be set to a distance where the user is highly likely to use the biometric device 100, but the second distance L2 is the intruder determination criterion. This is because a longer distance is better if a certain detection accuracy can be obtained. However, by setting L1 = L2, since the first threshold value ref1 and the second threshold value ref2 match, the storage capacity of the storage unit 22 can be reduced, and the same threshold value as in the first mode is read in the detection mode. The processing can be simplified because it is sufficient to put it out.

When the distance from the living body is equal to or less than the second distance L2, the determination result is “YES”, and the control unit 20 maintains the standby state and generates warning information indicating that there is an intruder ( S22 ). Thereafter, the control unit 20 controls the communication unit 29 to transmit the warning information to the outside (S23) . Specifically, the warning information is transmitted to the mail address of the terminal device 14 registered in advance. Thereby, the user of the terminal device 14 can know that someone has entered the house while going out.

  Next, the control unit 20 executes an alarm process for controlling the alarm unit 26 so as to issue an alarm to the intruder (S24). By issuing an alarm, an intruder can leave and reduce damage. Thereafter, the control unit 20 determines whether or not a release condition for canceling the alarm is satisfied (S25). There are various modes for releasing the alarm. The first mode is a method in which the user operates the operation unit 28 to input a release code. In this case, the user operates the operation unit 28 to register the release code in advance. The registered release code is stored in the storage unit 22. When canceling the alarm, the user operates the operation unit 28 to input a cancel code. In the determination process of step S20, the control unit 20 compares the input release code with the release code stored in the storage unit 22, and determines that the release condition is satisfied when the two match. In addition, when registering the release code in advance, the user is not limited to a mode in which the user transmits the release code to the biometric device 100 in advance using the terminal device 14 as described above. For example, the user may transmit the release code to the terminal device 14 using the biometric device 100, or may input a common release code to each of the biometric device 100 and the terminal device 14.

The second mode is a method of inputting a release code from the terminal device 14. In this case, the user transmits the release code to the biometric apparatus 100 in advance using the terminal device 14. When the communication unit 29 receives the release code, the control unit 20 stores the received release code in the storage unit 22. When canceling the alarm, the user operates the terminal device 14 to transmit a cancel code to the biometric device 100. In the determination process of step S2 5, it determines that the control unit 20 when the two are compared with release code stored and released code received in the storage unit 22 matches, release condition is satisfied.

  When the release condition is satisfied, the control unit 20 executes an alarm release process for stopping the operation of the alarm unit 26 (S26), and then changes the mode from the detection mode (second mode) to the first mode (S27). . Note that if the release condition is satisfied in a state where no warning information is transmitted, the control unit 20 changes the mode from the detection mode to the first mode. Therefore, after the user sets the detection mode, when the user returns to the home without an intruder, the user can shift to the first mode by performing a predetermined operation.

  Next, the watching mode will be described. As described above, the watching mode is a mode for notifying the user's activity to the outside. By setting the watching mode, for example, it is possible to confirm the safety of a family living apart. In the watching mode, the biological information M is generated in the same manner as in the first mode, and the control unit 20 generates activity information indicating the activity of the user based on the detection signal DC and uses the communication unit 29 to generate the activity information. Is sent to the outside. The transmission destination is, for example, an e-mail address registered in advance in the biometric apparatus 100.

  More specifically, in the watching mode, the control unit 20 determines whether the distance from the living body is equal to or less than the first distance L1 by comparing the detection signal DC with the first threshold value ref1, and the determination result. Is set to the use state when the distance is less than or equal to the first distance L1, while the standby state is set when the determination result exceeds the first distance L1. The control unit 20 generates the number of times of transition from the standby state to the use state in the predetermined period as activity information, and transmits this to the terminal device 14. In this case, the terminal device 14 is not owned by the user, but is owned by a family such as the user's child who watches the activities of the user.

The biometric device 100 is often placed in a place where the user conducts daily life, such as a living room or a washroom. For this reason, by generating as activity information the number of times the user to be watched approaches within the predetermined range from the biometric device 100, the user has a disorder such as a disease and daily life is not smoothly performed. It becomes possible for the family to know such things indirectly.
The predetermined period may be determined as appropriate, but may be one day, for example. Further, the activity information may be transmitted at a predetermined time. In addition, the biological information M measured during a predetermined period may be transmitted together with the activity information. Moreover, you may transmit the activity information which shows that the user was active, whenever it transfers to a use state from a standby state.

  As described above, according to the present embodiment, an intruder can be detected or a single user can be watched based on the detection signal DC, so that the convenience of the biometric device 100 can be improved. . In addition, since the detection unit 40 used for detecting an intruder can be used as the detection unit 40 used for determining the standby state and the use state in the first mode, the configuration is simplified while reducing power consumption. Can be Furthermore, in the watching mode, since the activity information is generated based on the determination result of the standby state and the use state in the first mode, it is not necessary to execute a special process to generate the activity information, and the process is simplified. At the same time, the user's activities can be notified to the outside while reducing power consumption.

<Modification>
The present invention is not limited to the above-described embodiments, and for example, the following modifications are possible. Moreover, each modification and embodiment can be combined suitably.
(1) In the above-described embodiment, the release code using the operation unit 28 or the terminal device 14 is described as an example of the release condition in the detection mode. However, the present invention is not limited to this. For example, the biometric information M of the user registered in advance is stored in the storage unit 22. When the user puts on the measuring table 122 when canceling the alarm, the control unit 20 detects that the user has placed on the measuring table 122 based on the measurement signal DA and shifts to the use state, and the biometric information M Perform measurement. In this case, power may be supplied to the weight detection unit 32 from the start of the detection mode, or power may be supplied to the weight detection unit 32 after detecting an intruder in the detection mode. In the latter case, power consumption can be reduced. Since the output of the measurement signal DA changes greatly when the user is placed on the measurement table 122, relatively low accuracy is sufficient for detecting that the user has been placed on the measurement table 122. Therefore, for example, power consumption can be reduced by performing A / D conversion of the measurement signal DA in the second mode at a sampling interval coarser than A / D conversion of the measurement signal DA in the first mode. Thereafter, the biometric information M read from the storage unit 22 is compared with the measured biometric information M, and when both are within a predetermined range, it may be determined that the cancellation condition is satisfied and the alarm may be canceled. The detection that the user is placed on the measurement table 122 may be determined by the control unit 20 comparing the detection signal DC with a determination threshold value. The determination threshold corresponds to the determination distance, and the determination distance may be set shorter than the first distance. Alternatively, when the determination result in step S21 shown in FIG. 8 is affirmative, the control unit 20 may shift from the standby state to the use state.
In addition, when the generated biological information and the biological information stored in the storage unit 22 are within a predetermined range, the control unit 20 cancels the transmission of the warning information or displays the already transmitted warning information. You may control the communication part 29 so that the information for withdrawing may be transmitted. This is because it is not necessary to send warning information when the user who has gone out returns to his home and cancels the warning. Alternatively, when one of the family members returns to their home and cancels the warning, the other family members can be reassured by transmitting the withdrawal of the warning information to the other family members.
Moreover, generating warning information is not essential in the present invention. In that case, steps S22 and S23 shown in FIG. 8 may be omitted. Further, the control unit 20 may shift the signal generation unit 30 from the standby state to the use state during or after executing the alarm process in step S24. Thereby, it is possible to generate the biological information M when the user is placed on the measurement table 122.

(2) Moreover, it is good also considering the activity meter which a user owns close to the biometric apparatus 100 as cancellation | release conditions. For example, in the health management system 1000 shown in FIG. 9, the activity meter 200 is a device that is carried by the user and that measures the activity based on the number of steps. The biometric apparatus 100 communicates with the activity meter 200 and transmits the activity amount information and the biological information M measured by the activity meter 200 to the server 300 together with identification information for identifying the user. The server 300 stores the identification information, the biological information M, and the activity amount information in association with each other. And when a user accesses the server 300 using the terminal device 14, the past | history etc. of the past biometric information M and activity amount information can be browsed. In such a health management system 1000, identification information is assigned to the activity meter 200, and the storage unit 22 of the biometric device 100 stores it in advance. When the activity meter 200 storing the identification information in advance is brought close to the biometric device 100, communication is performed, and the identification information of the activity meter 200 is transmitted to the biometric device 100. When the received identification information matches the identification information stored in the storage unit 22, the control unit 20 may execute the alarm release process (S26) shown in FIG.
Each of the various release conditions described above may be used alone, or two or more conditions may be used in combination. When two or more conditions are used in combination, they may be canceled when a plurality of conditions are satisfied, or may be canceled when any one of the conditions is satisfied.
In the above-described modification (1) and modification (2), the biological information M and the identification information are stored in the same storage unit 22. The storage unit 22 has a first storage area for storing the biological information M and a second storage area for storing the identification information. In this case, the first storage area functions as a first storage unit, while the second storage area functions as a second storage unit. Alternatively, a first storage unit that stores biological information M and a second storage unit that stores identification information may be provided separately.

(3) In the embodiment described above, the warning information and the activity information are transmitted from the biometric device 100 to the terminal device 14. However, the present invention is not limited to this, and any information may be used as long as it is transmitted to the outside. For example, in the health management system 1000 illustrated in FIG. 9, warning information and activity information may be transmitted to the server 300. In this case, the server 300 may notify the terminal device 14 of the warning information. On the other hand, the activity information may be viewed when accessed from the terminal device 14.

(4) In the watching mode of the embodiment described above, the control unit 20 generates the number of times of transition from the standby state to the use state in the predetermined period as the activity information, but the present invention is not limited to this, and the activity The information may be any information as long as it is information indicating the activity of the user generated based on the detection signal DC or the like. For example, the control unit 20 determines whether or not the distance from the living body is equal to or less than the third distance L3 by comparing the detection signal DC with the third threshold value ref3. The number of times of approaching within the range of the distance L3 may be generated as activity information. In this case, the first distance L1 and the third distance L3 do not necessarily need to match. However, the third distance L3 may be greater than or equal to the first distance L1. This is because if the user passes near the biometric apparatus 100, it can be seen that the user has moved in the room. The third distance L3 may coincide with the second distance L2.

(5) In the above-described embodiment, the communication unit 29 is provided and the warning information is transmitted to the outside. However, the present invention is not limited to this, and the communication unit 29 is not necessarily provided.
Moreover, although the biometric apparatus 100 of embodiment mentioned above was provided with 1st mode, detection mode, and watching mode (2nd mode), this invention is not limited to this, 1st mode and detection mode And a mode that does not include the watching mode, a mode that includes the first mode and the monitoring mode, and does not include the detection mode.
In the embodiment described above, the warning information is transmitted to the terminal device 14 of the user. However, the present invention is not limited to this, and the transmission destination is not limited as long as it is transmitted to the outside. For example, warning information may be transmitted to a security company.
In the above-described embodiment, the alarm unit 26 is provided. However, the present invention is not limited to this, and the alarm unit 26 may not be provided. In this case, for example, the warning information may be transmitted to an external control device, and the control device may turn on the TV or the sound device to increase the volume, or the lighting may be blinked, so that an alarm is given to the intruder. .

(6) In the above-described embodiment, in the first mode, the control unit 20 automatically switches between the use state and the standby state based on the detection signal DC, but the present invention is not limited to this. The user may manually switch the use state and the standby state by operating the operation unit 28. In this case, the control part 20 should just switch a use state and a standby state based on the output signal output from the operation part 28 according to a user's operation.

(7) The control unit 20 may control the communication unit 29 to transmit warning information to the outside when a predetermined condition is satisfied. The predetermined condition may be, for example, that the communication unit 29 has received opening / closing information indicating opening / closing supplied from a sensor that detects opening / closing of an entrance door, or an intruder is detected. It may be that one minute has passed since the detection.
Furthermore, the control unit 20 may cancel the transmission of the warning information when the warning information is not transmitted to the outside at the time when the alarm unit 26 is controlled to cancel the alarm. If the user accidentally approaches the biometric device 100 after setting to the detection mode, warning information is generated. However, according to this aspect, the transmission can be canceled before the warning information is transmitted, so that the user can be prevented from receiving meaningless warning information.
Moreover, the control part 20 may control the communication part 29 so that the confirmation information which shows having canceled the alarm may be transmitted outside, after controlling the alarm part 26 to cancel the alarm.

(8) In the embodiment described above, when the alarm is canceled in the detection mode, the control unit 20 automatically shifts the mode to the first mode, but the present invention is not limited to this. That is, it may be executed manually by operating the operation unit 28 by the user. In this case, the control unit 20 may shift from the detection mode (second mode) to the first mode based on an output signal output from the operation unit 28 in response to a user operation.

(9) In addition to the above-described embodiment, a backup power source or communication unit may be provided.
For example, in addition to the normal power source of the biometric device 100 (in the above-described embodiment, a battery inserted into the biometric device 100), another power source may be provided inside or outside the biometric device 100. . With such a configuration, even when the normal power supply of the biometric apparatus 100 is turned off, by using the other power source, it becomes possible to continuously detect and watch over the other power source.
Further, a communication unit different from the communication unit 29 of the biometric device 100 may be provided. For example, the communication type may be different so that the communication unit 29 can be connected to a so-called wireless LAN and the other communication unit can be connected to a mobile phone communication network. With this configuration, even when there is a problem in the communication unit 29 and / or the network to which the communication unit 29 is connected, transmission of information to the external device can be continued.
Thus, by providing a backup power supply and / or communication unit, it is possible to improve reliability in detection or watching. If a plurality of backup power supplies and / or communication units are provided, the reliability is further improved.
