Detailed description will be omitted.

  The configuration of the call system according to the present embodiment is the same as the configuration provided in the call system according to the second embodiment in place of mobile terminal 250 shown in FIG. 13 in place of mobile terminal 150 (see FIG. 12). .

  FIG. 13 is a block diagram of the mobile terminal 250.

  As illustrated in FIG. 13, the configuration of the mobile terminal 250 is the same as the configuration in which the mobile terminal 150 includes a GPS (Global Positioning System) unit 251 as a current position acquisition unit that acquires the current position.

  Next, the operation of the call system according to the present embodiment will be described.

  The operation of the call system according to the present embodiment is the same as the operation of the call system according to the second embodiment except for the operations described below. Of the operations of the call system according to the present embodiment, the same operations as those of the call system according to the second embodiment are denoted by the same reference numerals as those of the call system according to the second embodiment. Detailed description will be omitted.

  In the following, sleep (T1) will be described. However, the same applies to the nap (T4).

  When sleeping, the driver instructs the portable terminal 250 to start the function of the alarm clock via the operation unit 51 of the portable terminal 250. The operation unit 51 may include a dedicated switch for instructing the portable terminal 250 to start the function of the alarm clock.

  When the control unit 56 of the portable terminal 250 is instructed to start the function of the alarm clock, the control unit 56 starts a process similar to the process shown in FIG.

  That is, the set time notification unit 156b of the control unit 56 of the mobile terminal 250 instructs the sleep time measurement unit 156a of the control unit 56 of the mobile terminal 250 to start measuring the sleep time.

  The sleep time measurement unit 156a starts the process shown in FIG. 14 when the start of sleep time measurement is instructed.

  FIG. 14 is a flowchart of the operation of the portable terminal 250 when the sleep time measurement program 155a is executed.

  As shown in FIG. 14, the sleep time measuring means 156a of the control unit 56 of the portable terminal 250 determines whether or not there is a predetermined movement after the process of S72 (S161). Here, the predetermined movement is, for example, movement of 1 km or more, movement of 30 minutes or more. The predetermined movement is set in advance and stored in the storage unit 55, for example. The sleeping time measuring unit 156a determines whether or not there is a predetermined movement based on the history of the current position acquired by the GPS unit 251.

  When the sleep time measuring unit 156a determines in S161 that the predetermined movement has not occurred, the sleep time measuring unit 156a determines whether or not the set time notification unit 156b instructs the end of the measurement of the sleep time (S73).

  When the sleep time measuring means 156a determines in S73 that the end of the sleep time measurement is not instructed from the set time notification means 156b, the process returns to the process of S161 again.

  When the sleep time measuring means 156a determines in S161 that the predetermined movement has occurred, it determines whether or not the sleep time during the predetermined movement is set to be effective (S162). Whether or not the sleep time during the predetermined movement is effective is set in advance, and is stored in the storage unit 55, for example.

  If the sleep time measuring means 156a determines in S162 that the sleep time during the predetermined movement is set to be effective, it executes the process of S74.

  On the other hand, when the sleep time measuring unit 156a determines in S162 that the sleep time during the predetermined movement is set to be invalid, the measurement of the driver's sleep time, that is, the time measurement by the timer 151 is ended. (S163).

  Next, the sleep time measuring unit 156a deletes the sleep time start time stored in S71 from the storage unit 55 (S164), and ends the process shown in FIG.

  As described above, when the device for the to-be-called driver according to the present embodiment determines that there is a predetermined movement during the measurement of the sleep time (YES in S161), this measurement is performed. The process ends (S74, S163). That is, the to-be-called driver device according to the present embodiment treats the predetermined movement state as not sleeping. Therefore, the to-be-called driver device according to the present embodiment can improve the accuracy of measurement of the driver's sleep time.

  In addition, the to-be-called driver device according to the present embodiment treats a predetermined movement state as a state of not sleeping, so that, for example, a driver who originally has to sleep can earn even a little driving distance. It is possible to suppress the occurrence of riding without sleeping.

  In addition, when the device for to-be-called driver according to the present embodiment determines that there is a predetermined movement during the measurement of the sleep time (YES in S161), depending on the setting, the device can be obtained by this measurement. The sleep time that is displayed is invalidated (NO in S162). Therefore, the device for the to-be-called driver according to the present embodiment suppresses the predetermined movement during the measurement of the sleep time to the driver who wishes to prevent the sleep time obtained by the measurement from being invalidated. Therefore, it is possible to make the driver take sleep appropriately.

  On the other hand, if it is determined that there is a predetermined movement during the measurement of the sleep time (YES in S161), the to-be-called driver device according to the present embodiment obtains this measurement depending on the setting. Enabled sleep time (YES in S162). Therefore, the to-be-called driver device according to the present embodiment is a case where the driver forgets to give an instruction to end the function of the alarm clock, that is, to end the measurement of the sleep time. However, the sleep time can be stored effectively.

  It should be noted that the to-be-called driver device according to the present embodiment can be configured to set whether or not to enable sleep time obtained by measurement when it is determined that a predetermined movement has occurred. It has become. However, if the device for the to-be-called driver determines that there is a predetermined movement during the measurement of the sleep time, whether or not to enable the sleep time obtained by this measurement is fixed. Also good.

  The to-be-called driver device according to the present embodiment includes GPS unit 251 in portable terminal 250 in the present embodiment. However, the apparatus for a to-be-called driver according to the present embodiment may include a GPS unit in alcohol measurement terminal 140.

  The present position acquisition means of the present invention is realized by a GPS unit in the present embodiment. However, the current position acquisition means of the present invention may be realized by a device other than the GPS unit as long as it can acquire the current position.

  In the to-be-called driver device according to the present embodiment, mobile terminal 250 executes sleep time measurement program 155a for measuring the sleep time of the driver. However, the device for the to-be-called driver has a sleeping time measurement program for measuring the sleeping time of the driver, similarly to the to-be-called driver device 30 (see FIG. 4) according to the first embodiment. The alcohol measurement terminal 140 may be executed.

  Next, the sleep time measuring unit 156a executes a sleep quality determination process that is a process of determining the level of the driver's sleep quality by the sleep quality determination unit 356a (S364).

  FIG. 18 is a flowchart of the sleep quality determination process in S364.

  As shown in FIG. 18, the sleep quality determination unit 356a determines whether or not the average value of the sound levels of surrounding sounds that have been detected in S361 and ended in S362 is 20 dB or less (S371).

  When the sleep quality determination means 356a determines in S371 that the average value of the volume of surrounding sounds is not 20 dB or less, the average value of the volume of surrounding sounds that started detection in S361 and ended detection in S362 is 40 dB or more. It is determined whether or not (S372).

  When the sleep quality determination unit 356a determines in S371 that the average value of the volume of surrounding sounds is 20 dB or less, the average value of ambient brightness that started detection in S361 and ended detection in S362 is 0.3. It is determined whether it is less than lux (S373).

  When the sleep quality determination means 356a determines in S372 that the average value of the volume of surrounding sounds is not 40 dB or more, or in S373 that the average value of the ambient brightness is not 0.3 lux or less, in S361 It is determined whether or not the average value of the surrounding brightness that has been detected and ended in S362 is 30 lux or more (S374).

  When the sleep quality determination unit 356a determines in S373 that the average value of the ambient brightness is 0.3 lux or less, the sleep number of times that the measurement is started in S361 and the measurement is ended in S362 is stored in S76. It is determined whether or not the number of times divided by time, that is, the number of times of turning over per hour is not less than 2.5 and not more than 3.75 (S375).

  The sleep quality determination means 356a determines in S374 that the average value of ambient brightness is not 30 lux or more, or in S375 that the number of turns per hour is not 2.5 or more and 3.75 or less. If it judges, it will be judged whether the number of times of turning over per hour is 1 time or less, or 5 times or more (S376).

  When the sleep quality determination means 356a determines in S375 that the number of times of turning over per hour is 2.5 times or more and 3.75 times or less, the sleep quality determination means 356a determines that the level of sleep quality of the driver is “high” ( S377), the process shown in FIG.

  If the sleep quality determination means 356a determines in S376 that the number of times of wake-up per hour is not less than 1 and not more than 5 in S376, the sleep quality level of the driver is determined as “medium” (S378). Then, the process shown in FIG.

  The sleep quality determination unit 356a determines in S372 that the average value of the volume of surrounding sounds is 40 dB or more, or determines in S374 that the average value of ambient brightness is 30 lux or more, or per hour. If it is determined in S376 that the number of times of turning over is 1 or less or 5 or more, the level of sleep quality of the driver is determined as “low” (S379), and the process shown in FIG. 18 is terminated.

  Note that 20 dB and 40 dB in FIG. 18 are the first sound volume threshold value and the second sound volume threshold value that are preset and stored in the threshold information 355c (see FIG. 16) on the storage unit 55, respectively. In FIG. 18, 0.3 lux and 30 lux are a first brightness threshold and a second brightness threshold that are preset and stored in the threshold information 355c on the storage unit 55, respectively. In FIG. 18, 1st, 2.5th, 3.75th, and 5th are respectively set in advance as threshold values 355c on the storage unit 55 and stored in the threshold information 355c. It is a third turnover number threshold and a fourth turnover number threshold.

  As illustrated in FIG. 17, when the sleep time measurement unit 156a of the control unit 56 of the mobile terminal 350 finishes the sleep quality determination process of S364, the level of the driver's sleep quality determined in the sleep quality determination process of S364. Is stored in the storage unit 55 (S365), and the process shown in FIG.

  FIG. 19 is a diagram illustrating an example of vibration detected by the triaxial acceleration sensor 353 when the driver sleeps. In FIG. 19, the upper graph is a graph showing the amplitude of vibration detected by the triaxial acceleration sensor 353. The lower graph is a graph showing the sleep depth of the driver.

  As shown in FIG. 19, the vibration detected by the triaxial acceleration sensor 353 is a large vibration in a period 381 immediately after the start of sleep time measurement. The sleep depth of the driver in this period 381 is the first mountain 391, and the driver is still awake.

  Next, the vibration detected by the triaxial acceleration sensor 353 is a small vibration in a period 382 following the period 381. The driver's sleep depth in this period 382 gradually decreases from the mountain 391 and reaches the first valley 392, and then gradually increases. In the valley 392, the driver's sleep state is a non-REM sleep state.

  Next, the vibration detected by the triaxial acceleration sensor 353 is a large vibration in the period 383 following the period 382. The driver's sleep depth in this period 383 gradually increases and reaches the second mountain 393. In the mountain 393, the driver's sleep state is a REM sleep state.

  Next, the vibration detected by the triaxial acceleration sensor 353 is a small vibration in a period 384 following the period 383. The driver's sleep depth in this period 384 is a mountain 393.

  Next, the vibration detected by the triaxial acceleration sensor 353 is a large vibration in a period 385 following the period 384. The sleep depth of the driver in this period 385 gradually decreases from the mountain 393.

  Next, the vibration detected by the triaxial acceleration sensor 353 is a small vibration in the period 386 following the period 385. The sleep depth of the driver in this period 386 gradually decreases and then gradually increases after reaching the second valley 394. In the valley 394, the sleep state of the driver is a non-REM sleep state.

  Thereafter, similarly, every time the driver's sleep state repeats non-REM sleep and REM sleep, the vibration pattern detected by the triaxial acceleration sensor 353 is also repeated.

  Here, the large vibration in the first period 381 is vibration when the driver is awake, and is not estimated to be vibration due to turning over.

  On the other hand, large vibrations in periods other than the period 381, such as the period 383 and the period 385, are vibrations when the driver is sleeping, and are estimated to be vibrations caused by turning over. The vibration due to turning over is characterized by a larger amplitude than the vibration due to respiration. Further, the vibration due to turning over is characterized by a large variation in amplitude compared with the vibration due to respiration. In addition, the time when the period in which vibration due to turning over appears is the time when the transition from non-REM sleep to REM sleep and the time when the transition from REM sleep to non-REM sleep is characteristic. That is, there is a feature that the periods in which vibrations caused by rolling over occur at intervals of several tens of minutes.

  In addition, small vibrations in a period between large vibrations such as the period 382, the period 384, and the period 386 are vibrations when the driver is sleeping, and are estimated to be vibrations due to breathing. . The vibration due to respiration has a characteristic that the amplitude is smaller than the vibration due to turning over. Further, vibration due to respiration has a characteristic that variation in amplitude is smaller than vibration due to turning over. Further, vibration due to breathing is characterized by a short periodicity of about 5 to 10 seconds.

  FIG. 20 is a flowchart of the operation of the mobile terminal 350 when the measurement of the number of times of turning is executed.

  When the measurement of the number of times of turning is started in S361 described above, the number of times of turning measuring unit 356b of the control unit 56 executes the process shown in FIG.

  As shown in FIG. 20, the rolling number measuring means 356 b ends the period of vibration with a large amplitude until it determines that the period of vibration with a large amplitude has ended based on the vibration detected by the triaxial acceleration sensor 353. It is determined whether or not it has been done (S401). That is, the turnover number measuring unit 356b determines whether or not the period during which the driver is awake has ended. Here, when the above-described characteristic of vibration due to respiration occurs in the vibration detected by the three-axis acceleration sensor 353, the turn-over frequency measuring unit 356b determines that the period of vibration with a large amplitude has ended. In addition, the number-of-turns measuring unit 356b does not measure the number of vibrations during the period when the driver is awake as the number of times of turning.

  When the turn-over measuring unit 356b determines in S401 that the period of vibration with a large amplitude has ended, until it determines that the period of vibration with a small amplitude has ended based on the vibration detected by the triaxial acceleration sensor 353, It is determined whether or not the vibration period with a small amplitude has ended (S402). That is, the number-of-turns measuring unit 356b determines whether or not the period in which vibration due to respiration appears has ended. Here, when the number of times of turning over is measured by the triaxial acceleration sensor 353 and the characteristic of vibration caused by turning over is generated in the vibration detected by the triaxial acceleration sensor 353, it is determined that the period of vibration with a small amplitude has ended. Note that the turn-over frequency measuring means 356b stores the vibration amplitude during the vibration period with a small amplitude as a reference for the vibration amplitude caused by respiration, and distinguishes between vibration caused by respiration and vibration caused by turning over in subsequent processing. Can be used to improve accuracy. Further, the turning number measuring unit 356b does not measure the number of times of vibration in the period of vibration with a small amplitude as the number of times of turning.

  If the turn-over measuring unit 356b determines in S402 that the period of vibration with a small amplitude has ended, it determines whether or not the period of vibration with a large amplitude has ended based on the vibration detected by the triaxial acceleration sensor 353. (S403). In other words, the turnover number measuring unit 356b determines whether or not the period in which the vibration due to the turnover appears has ended. Here, when the above-described characteristic of vibration due to respiration occurs in the vibration detected by the three-axis acceleration sensor 353, the turn-over frequency measuring unit 356b determines that the period of vibration with a large amplitude has ended.

  If it is determined in S403 that the period of vibration with a large amplitude has not ended, the rolling number measuring unit 356b determines whether or not a vibration peak, that is, a peak or a valley has occurred (S404).

  If the turn-over number measuring unit 356b determines in S404 that a vibration peak has occurred, the turn-over number measuring unit 356b increases the number of turn over during measurement by 1 (S405).

  The turn-over number measuring unit 356b determines in step S404 that no vibration peak has occurred or ends the process in step S405, and then returns to the process in step S403 again.

  When the turn-over number measuring unit 356b determines in S403 that the period of vibration with a large amplitude has ended, the process returns to the process of S402 again.

  When executing the processing shown in FIG. 9, the call information transmitting means 56a of the portable terminal 350 includes the driver's crew ID and the driver's breath in the call information transmitted to the call executor device 20. In addition to the concentration of alcohol contained, the time when measurement of the concentration of alcohol contained in the driver's breath was executed, the sleep time of the driver, the start time and the end time of sleep time, stored in the storage unit 55 The average value and the maximum value of the volume of the ambient sound being recorded, the average value and the maximum value of the ambient brightness stored in the storage unit 55, the number of times of turning over stored in the storage unit 55, and the storage The detection result of the no-vibration state stored in the unit 55 and the level of the driver's sleep quality are included.

  When setting the threshold for the volume of the surrounding sound, the driver instructs the portable terminal 350 to start setting the threshold for the volume of the surrounding sound via the operation unit 51 of the portable terminal 350.

  The control unit 56 of the portable terminal 350 starts the process shown in FIG. 21 when instructed to start setting a threshold value for the volume of surrounding sounds.

  FIG. 21 is a flowchart of the operation of the mobile terminal 350 when a threshold value for the volume of surrounding sounds is set.

  As shown in FIG. 21, the threshold setting unit 356d of the control unit 56 of the portable terminal 350 starts detecting the volume of surrounding sounds by the microphone 351 (S411).

  Next, the threshold setting unit 356d determines whether or not the predetermined time has elapsed until it is determined that the predetermined time has elapsed (S412). The predetermined time can be selected in advance by the driver via the operation unit 51 for a short time such as 1 minute or a long time such as 8 hours.

  If the threshold value setting unit 356d determines in S412 that the predetermined time has elapsed, the threshold value setting unit 356d ends the detection of the volume of surrounding sounds by the microphone 351 (S413).

  Next, the threshold value setting unit 356d sets the first sound volume threshold value and the second sound volume threshold value on the storage unit 55 based on the average value of the sound volume of surrounding sounds that started detection in S411 and ended detection in S413. It is set to 355c (S414). For example, the threshold setting unit 356d substitutes the average value of the volume of surrounding sounds that started detection in S411 and ended detection in S413 into a preset mathematical formula, thereby setting the first volume threshold and the second volume. Calculate the threshold.

  The threshold setting unit 356d ends the process shown in FIG. 21 after the process of S414.

  When setting the threshold value for the ambient brightness, the driver instructs the portable terminal 350 to start setting the threshold value for the ambient brightness via the operation unit 51 of the portable terminal 350.

  When the control unit 56 of the portable terminal 350 is instructed to start setting a threshold value for ambient brightness, the control unit 56 starts the process shown in FIG.

  FIG. 22 is a flowchart of the operation of the mobile terminal 350 when a threshold for ambient brightness is set.

  As shown in FIG. 22, the threshold setting unit 356d of the control unit 56 of the mobile terminal 350 starts detecting ambient brightness by the photodiode 352 (S421).

  Next, the threshold setting unit 356d determines whether or not the predetermined time has elapsed until it is determined that the predetermined time has elapsed (S422). The predetermined time can be selected in advance by the driver via the operation unit 51 for a short time such as 1 minute or a long time such as 8 hours.

  When the threshold value setting unit 356d determines in S422 that the predetermined time has elapsed, the detection of ambient brightness by the photodiode 352 ends (S423).

  Next, the threshold setting unit 356d sets the first brightness threshold and the second brightness threshold on the storage unit 55 based on the average value of the surrounding brightness that started detection in S421 and ended detection in S423. Information 355c is set (S424). For example, the threshold value setting unit 356d substitutes the average value of the surrounding brightness, which has been detected in S421 and ended in S423, into a previously set mathematical formula, thereby setting the first brightness threshold value and the second brightness value. The threshold value is calculated.

  The threshold setting unit 356d ends the process shown in FIG. 22 after the process of S424.

  When the driver sets a threshold for the number of times the driver turns over, the driver instructs the portable terminal 350 to start setting the threshold for the number of turns of the driver via the operation unit 51 of the portable terminal 350.

  The control unit 56 of the portable terminal 350 starts the process shown in FIG. 23 when instructed to start the setting of the threshold value with respect to the number of times the driver turns over.

  FIG. 23 is a flowchart of the operation of the mobile terminal 350 when a threshold value for the number of times the driver turns over is set.

  As shown in FIG. 23, the threshold setting unit 356d of the control unit 56 of the portable terminal 350 starts measuring the number of times of turning by the triaxial acceleration sensor 353 and the number of times of turning measuring unit 356b (S431).

  Next, the threshold setting unit 356d determines whether or not the predetermined time has elapsed until it is determined that the predetermined time has elapsed (S432). The predetermined time can be selected in advance by the driver via the operation unit 51 as a long time such as 8 hours.

  If the threshold setting unit 356d determines in S432 that the predetermined time has elapsed, the threshold setting unit 356d ends the measurement of the number of times of turning by the triaxial acceleration sensor 353 and the number of times of turning measuring unit 356b (S433).

  Next, the threshold setting unit 356d determines the first turnover threshold value based on the number of times of turning over the number of times of turning turned over in the measurement time, that is, the number of times of turning turned over at the measurement time in S431. Then, the second turning number threshold value, the third turning number threshold value, and the fourth turning number threshold value are set in the threshold information 355c on the storage unit 55 (S434). For example, the threshold setting unit 356d substitutes the number of times of turning per hour into a preset mathematical formula, thereby setting the first turning number threshold, the second turning number threshold, the third turning number threshold, and the fourth turning number. Calculate the threshold.

  The threshold setting unit 356d ends the process shown in FIG. 23 after the process of S434.

  In the above, the setting of the threshold for the volume of the surrounding sound, the setting of the threshold for the surrounding brightness, and the setting of the threshold for the number of times the driver turns over are performed separately. Two or more may be executed simultaneously.

  As described above, the device for the to-be-called driver according to the present embodiment allows the call executor to grasp the sleep quality of the driver based on the sound volume around the driver who is sleeping. As a result, it is possible to make the call executor more appropriately determine whether there is no problem in the driving operation of the vehicle by the driver, compared with the configuration in which the call executor only knows the sleeping time concerning the sleep of the driver. it can. Note that the call executor can also advise the driver about improvement of the sleep environment at the time of the call based on the volume of sound around the driver during sleep. Here, the volume of sound around a human being sleeping is generally suitable for sleep if it is 20 dB or less, and is not suitable for sleep if it is 40 dB or more.

  In addition, since the device for the to-be-called driver according to the present embodiment can make the call executor know the quality of sleep of the driver based on the brightness around the driver during sleep, Compared to a configuration in which only the sleep time is grasped by the call executor with respect to sleep, the call executor can be more appropriately determined whether or not there is no problem in the driving operation of the vehicle by the driver. Note that the call executor can also advise the driver about the improvement of the sleep environment at the time of the call based on the brightness around the driver during sleep. Here, as for the brightness of the surroundings of a human being sleeping, generally about 0.3 lux is best for sleep, and it is said that 30 lux or more is not suitable for sleep.

  In addition, the device for the to-be-called driver according to the present embodiment can cause the call executor to grasp the quality of the driver's sleep based on the number of times the driver has turned over while sleeping. As compared with the configuration in which only the sleep time is grasped by the call executor, the call executor can be more appropriately determined as to whether or not the driving operation of the vehicle by the driver is not hindered. Here, the number of times the driver turns over during sleep is generally considered to be about 20 to 30 times for an 8-hour sleep. Therefore, the call executor can determine that the driver's body is fatigued, for example, when the number of the driver's turning while sleeping is extremely small, and the driver's sleeping while sleeping When the number of times is extremely large, it can be determined that the driver is not in deep sleep.

  In addition, the device for the to-be-called driver according to the present embodiment is based on the sound volume around the driver during sleep (S371, S372), and the level of the sleep quality of the driver (S377, S378, S379). Therefore, it is possible to make it easier for the caller to grasp the driver's sleep. The call executor can make a more appropriate decision.

  In addition, the to-be-called driver device according to the present embodiment is based on the surrounding brightness of the driver during sleep (S373, S374), and the driver's sleep quality is determined by the level (S377, S378, S379). Compared with the configuration that allows the call executor to grasp the sleep time only for the driver, the call executor can easily grasp the driver's sleep. Enforcer can make judgment more appropriately.

  In addition, the to-be-called driver device according to the present embodiment calls the driver's sleep quality based on the number of times the driver has turned over during sleep (S375, S376) according to the level (S377, S378, S379). Since it can be easily understood by the executor, the call execution of whether there is no problem in the driving operation of the vehicle by the driver compared with the configuration in which only the sleeping time is grasped by the call executor regarding the driver's sleep. Can be made to judge more appropriately.

  Further, the to-be-called driver device according to the present embodiment is based on the magnitude and periodicity of the vibration detected by the three-axis acceleration sensor 353, and the vibration caused by the driver turning over and the vibration caused by the driver breathing. Therefore, it is possible to improve the accuracy of measurement of the number of times the driver turns over while sleeping.

  In addition, since the apparatus for a to-be-called driver according to the present embodiment includes the detection result by the no-vibration state detecting means 356c in the information for call 24a, vibration due to breathing, turning over, etc. that should occur during sleep. It is possible to make the call executor grasp the occurrence of the absence state. Therefore, the to-be-called driver device according to the present embodiment can suppress the occurrence of measurement of sleep time in which sleep is disguised.

  In addition, the to-be-called driver device according to the present embodiment uses the same three-axis acceleration sensor 353 for the measurement of the number of times the driver rolls over and the detection of the no-vibration state. Compared to the configuration used, the number of parts can be reduced.

  Further, the to-be-called driver apparatus according to the present embodiment includes the time when the no-vibration state occurs as the detection result by the no-vibration state detecting means 356c, so that the measured sleep is measured. The call executor can be made aware of the time during which the driver may not be sleeping.

  Moreover, since the apparatus for to-be-called drivers which concerns on this Embodiment sets a 1st volume threshold value and a 2nd volume threshold value based on the volume detected by the microphone 351 (S414), a driver | operator's actual sleep environment The first sound volume threshold and the second sound volume threshold can be set according to. Therefore, the to-be-called driver device according to the present embodiment can appropriately determine the level of sleep quality of the driver. For example, in the device for the to-be-called driver according to the present embodiment, when the mobile terminal 350 is placed in an ideal sleep environment or a sleep environment at the driver's home when the first volume threshold and the second volume threshold are set. Since the first sound volume threshold and the second sound volume threshold corresponding to the sleep environment are set, the sleep of the driver in the sleep environment on the go is based on the ideal sleep environment and the sleep environment at the driver's home. The quality level can be determined appropriately.

  In addition, the to-be-called driver device according to the present embodiment sets the first brightness threshold and the second brightness threshold based on the brightness detected by the photodiode 352 (S424). It is possible to set the first brightness threshold and the second brightness threshold according to the actual sleep environment. Therefore, the to-be-called driver device according to the present embodiment can appropriately determine the level of sleep quality of the driver. For example, in the to-be-called driver device according to the present embodiment, the portable terminal 350 is placed in an ideal sleep environment or a sleep environment at the driver's home when the first brightness threshold and the second brightness threshold are set. In this case, the first brightness threshold and the second brightness threshold are set according to the sleep environment, so driving in the sleep environment on the go is based on the ideal sleep environment and the sleep environment at the driver's home. The level of sleep quality of the person can be appropriately determined.

  In addition, the to-be-called driver device according to the present embodiment has a first turnover threshold and a second turnover based on the number of turns of the driver measured based on the vibration detected by the three-axis acceleration sensor 353. Since the number-of-thresholds, the third number-of-turns-threshold, and the number-of-four-throws-threshold-threshold are set (S434), the first number-of-turns-threshold threshold, the second number-of-turns-threshold, the third number-of-turns-threshold A fourth turnover frequency threshold can be set. Therefore, the to-be-called driver device according to the present embodiment can appropriately determine the level of sleep quality of the driver. For example, in the device for the to-be-called driver according to the present embodiment, the portable terminal 350 performs an ideal sleep when setting the first turn-over frequency threshold, the second turn-over frequency threshold, the third roll-over frequency threshold, and the fourth roll-over frequency threshold. When placed in the environment or the sleep environment of the driver's home, the first turnover threshold, the second turnover threshold, the third turnover threshold and the fourth turnover threshold are set according to the sleep environment, Based on the ideal sleep environment and the sleep environment at the driver's home, it is possible to appropriately determine the level of the sleep quality of the driver in the sleep environment on the go.

  Note that the to-be-called driver device according to the present embodiment includes a microphone 351 in the portable terminal 350 in the present embodiment. However, the apparatus for a to-be-called driver according to the present embodiment may include a microphone in alcohol measurement terminal 140.

  In addition, the to-be-called driver device according to the present embodiment includes photodiode 352 in portable terminal 350 in the present embodiment. However, the device for the to-be-called driver according to the present embodiment may include a photodiode in the alcohol measurement terminal 140.

  In the present embodiment, the illuminance sensor of the present invention is realized by a photodiode. However, the illuminance sensor of the present invention may be realized by a configuration other than the photodiode as long as the ambient brightness can be detected.

  For example, the illuminance sensor of the present invention, as shown in FIG. 24, obtains brightness of surroundings based on a camera 354 such as a CCD (Charge Coupled Device) image sensor and an image photographed by the camera 354. It may be realized by means 356e. The brightness acquisition unit 356e is a function realized by the control unit 56 executing the sleep time measurement program 355a. The brightness acquisition unit 356e obtains an average value of RGB R values, an average value of G values, and an average value of B values of all pixels included in all or a part of an image photographed by the camera 354. The brightness of the surroundings is acquired by converting to lux based on the calculated average value of the R value, the average value of the G value, and the average value of the B value. In the case of the configuration of the to-call driver according to the present embodiment, as shown in FIG. 24, if the camera 354 is provided, the device around the driver who is sleeping can be provided even if the camera 354 is not provided. Brightness can be detected.

  The to-be-called driver device according to the present embodiment includes a three-axis acceleration sensor 353 in portable terminal 350 in the present embodiment. However, the device for the to-be-called driver according to the present embodiment may include a triaxial acceleration sensor in the alcohol measurement terminal 140.

  The vibration sensor of the present invention is realized by a triaxial acceleration sensor in the present embodiment. However, the vibration sensor of the present invention may be realized by a sensor other than the triaxial acceleration sensor as long as it can detect vibration.

  In the device for the to-be-called driver according to the present embodiment, the portable terminal 350 executes a sleep time measurement program 355a for measuring the sleep time of the driver. However, the device for the to-be-called driver has a sleeping time measurement program for measuring the sleeping time of the driver, similarly to the to-be-called driver device 30 (see FIG. 4) according to the first embodiment. The alcohol measurement terminal 140 may be executed.

  The device for the to-be-called driver according to the present embodiment determines that there has been a predetermined movement during the measurement of the sleep time, similarly to the device for the to-be-called driver according to the third embodiment. In this case, this measurement may be terminated.

  It should be noted that the roll call in each of the above-described embodiments is a telephone call that is executed while the call executor and the driver are talking over the telephone. However, the present invention is a face-to-face call that is performed while the call executor and the driver are actually facing each other, and IT (Information) that is performed while the call executor and the driver are facing each other in the video of the information terminal on the network. It can also be applied to a call other than a telephone call, such as (Technology).

  In each of the above-described embodiments, it is assumed that the device for call execution and the device for callee driver are used in places separated from each other, but at least the device for callee driver When the call information is transmitted from the device to the call executor device, the call executor device and the to-be-called driver device may be used in close proximity to each other.

  For example, a driver for a to-be-called driver is used by a driver of a business vehicle such as a route bus having a short operating distance, and a portable terminal of the to-be-called driver device is carried by the driver, The alcohol measurement terminal of the device for the to-be-called driver is installed in the business office where the call-executor is located, and at least at the time of transmitting the information for the call to the device for the call-executor from the mobile terminal, The configuration may be such that the device for the to-be-called driver is used at the same business office. Here, as an example of a connection method between the mobile terminal and the call execution device, physical connection such as USB (Universal Serial Bus) connection, Wi-Fi (registered trademark), Bluetooth (registered trademark), etc. There are short-range wireless communication and proximity non-contact communication such as infrared communication, one-dimensional barcode, and two-dimensional barcode.
