The CPU has a function of reading and executing a program or the like stored in advance in the storage unit 50. The control unit 80 can be realized by software executed by a microcomputer, for example, but a part thereof may be configured by hardware.

  Hereinafter, control that can confirm the safety of a worker even when the worker is working will be described. FIG. 3 is a flowchart illustrating an example of a processing procedure executed by the control unit 80 when confirming the safety of a worker or the like.

  Referring to FIG. 3, control starts when an operator or the like wraps wristwatch-type biological information transmission device 1 around his / her arm. The wearing of the biological information transmission device 1 by an operator or the like is determined based on, for example, the body temperature measuring unit 20 detecting the body temperature. When the control starts, in step S1, the control unit 80 determines whether or not a predetermined time has come based on a signal from the GPS receiving unit 10. The predetermined time is composed of one or more specific times, and data of the predetermined time is stored in the storage unit 50 in advance. If a negative determination is made in step S1, the process proceeds to step S5. The process of step S5 will be described later. On the other hand, if a positive determination is made in step S1, the process proceeds to step S2.

  In step S <b> 2, the control unit 80 determines whether there is an abnormality in at least one of body temperature, arm movement, and pulse. Specifically, in step S <b> 2, the control unit 80 determines whether the body temperature of the worker or the like specified based on the signal from the body temperature measurement unit 20 is included in the normal body temperature range stored in the storage unit 50 in advance. Determine whether. The control unit 80 determines that the body temperature is normal when the body temperature of the identified worker or the like is included in a normal body temperature range, and otherwise determines that the body temperature is abnormal.

  Further, the control unit 80 determines whether or not an acceleration difference of a predetermined magnitude or more has been detected during a predetermined time based on a signal from the acceleration measurement unit 30. Data for a predetermined time and data on the magnitude of acceleration serving as a threshold are stored in the storage unit 50 in advance. If the control unit 80 determines that an acceleration difference greater than or equal to a predetermined magnitude is detected during a predetermined time, the control unit 80 determines that the arm movement is normal, and otherwise determines that the arm movement is abnormal. .

  Further, the control unit 80 determines whether or not the pulse rate specified based on the signal from the pulse measurement unit 40 is included in the range of normal pulse rates stored in the storage unit 50 in advance. The control unit 80 determines that the pulse rate is normal when the pulse rate of the specified worker or the like is included in the normal pulse rate range, and determines that the pulse rate is abnormal otherwise. The control unit 80 determines whether or not an abnormality is observed in at least one of body temperature, arm movement, and pulse by making these three determinations.

  When an affirmative determination is made in step S <b> 2, the process proceeds to step S <b> 3, and the control unit 80 causes the transmission unit 60 to transmit a signal indicating that the state of the worker or the like is abnormal to the external device. The external device is composed of a mobile phone such as a worker, for example. This transmission is performed using, for example, Bluetooth (registered trademark) from the biological information transmitting apparatus 1 to a mobile phone such as an operator. Bluetooth is a microwave (radio wave) having a specified frequency. This Bluetooth signal is an example of a determination signal.

  The Bluetooth includes device authentication information for determining whether the mobile phone is a device that is allowed to communicate with the biometric information transmitter 1, and information indicating an abnormal signal or a normal signal. For example, the abnormal signal and the normal signal are different in at least one of the phase and the amplitude in a region indicating abnormality or normality in Bluetooth. By differentiating at least one of the phase and the amplitude, the two signals can be distinguished.

  When the cellular phone receives an abnormal signal from the biological information transmitting device 1, the mobile phone transmits a signal representing the abnormality of the worker or the like by the application to the movement management device that manages the movement of each worker or the like. When the movement management device receives an abnormality signal from the mobile phone, it transmits a signal representing the abnormality of a specific worker or the like to a predetermined portable terminal or the like. As a result, the predetermined owner of the portable terminal or the like can recognize an abnormality such as a specific worker. In addition, the biological information transmission device may directly transmit a signal representing an abnormality of a worker or the like to the movement management device using radio waves. In this case, the movement management device constitutes an external device. When step S3 is completed, the process proceeds to step S5.

  On the other hand, if a negative determination is made in step S2, the process proceeds to step S4. In step S4, the control unit 80 causes the transmission unit 60 to transmit a signal indicating that the state of the worker or the like is normal to the mobile phone or the like of the worker, and the mobile phone or the like of the worker or the like A signal representing the normality of the employee is transmitted to the movement management device. When step S4 is completed, the process proceeds to step S5.

  In step S5, the control unit 80 determines whether or not the biological information transmitting apparatus 1 has been removed from the arm of a worker or the like. This determination is performed by the control unit 80 based on a signal from the body temperature measurement unit 20 or the pulse measurement unit 40, for example. If a negative determination is made in step S5, step S1 and subsequent steps are repeated. On the other hand, if an affirmative determination is made in step S5, the control ends.

  According to the above-described embodiment, even when a worker or the like is working, at a predetermined time, the control unit determines whether or not the worker or the like is in a normal state based on a signal from the biological information detection unit. A determination signal that can be determined is transmitted to the movement management device via the mobile phone of the worker or the like. Therefore, it can be determined whether or not the worker or the like is in a normal state, and the field work can be performed more smoothly.

  In addition, since the biological information transmitting apparatus 1 can be attached to and detached from a person's arm, an operator or the like can easily attach the biological information transmitting apparatus. In addition, since the biological information detection unit detects a person's pulse, a person's body temperature, and an arm's movement, which can easily determine the movement of the worker and the like, the movement and the movement of the worker and the like can be accurately determined. Etc. can be judged accurately.

  In addition, when the biological information transmitting apparatus 1 includes the GPS receiving unit 10 and the control unit 80 determines that the predetermined time has come based on the signal from the GPS receiving unit 10, the biological information transmitting apparatus 1 transmits a determination signal. Therefore, it is possible to accurately determine the movement of the worker or the like at a predetermined time, and to determine the safety of the worker or the like.

  Furthermore, the biological information transmission device 1 includes a GPS receiving unit 10 that specifies the location. Therefore, it is possible to specify the location of the worker or the like wearing the biological information transmitting device 1, and when the worker or the like is in an abnormal state, the worker or the like can be rescued quickly.

  The present invention is not limited to the above-described embodiment and its modifications, and various improvements and modifications can be made within the matters described in the claims of the present application and their equivalent ranges.

  For example, in the above-described embodiment, the case where the biological information transmission device 1 transmits a determination signal that can determine whether or not the biological signal is in the normal range at a predetermined time to the external device via the transmission unit 60 has been described. However, the biological information transmitting apparatus may include a receiving unit that receives a transmission request signal for requesting transmission of a signal from an external device, and when the receiving unit receives the transmission request signal, the transmitting unit may transmit a determination signal. In this way, in addition to the transmission unit transmitting the determination signal to the external device at a predetermined time, when the reception unit receives the transmission request signal even at a time other than the predetermined time, the transmission unit transmits the determination signal. You may make it transmit to an external apparatus. Alternatively, only when the reception unit receives the transmission request signal, the transmission unit may transmit the determination signal to the external device, and the transmission unit may not transmit the determination signal to the external device at a predetermined time. In this case, the biological information transmission device may not have a time specifying unit that specifies time.

  For example, when the biological information transmitting apparatus receives a transmission request signal from the first external device via the receiving unit at a time other than a predetermined time, the transmitting unit transmits a signal indicating the time and a signal indicating the location to the second external device. May be. In addition, when the biological information transmitting apparatus receives a transmission request signal from the first external device via the receiving unit at a time other than the predetermined time, the transmitting unit transmits a signal representing the body temperature of the worker or the like to the second external device. Also good.

  Further, when the biological information transmitting apparatus receives a transmission request signal from the first external device via the receiving unit at a time other than the predetermined time, the transmitting unit may transmit a signal representing acceleration to the second external device. In addition, when the biological information transmitting apparatus receives a transmission request signal from the first external device via the receiving unit at a time other than the predetermined time, the transmitting unit transmits a signal representing the pulse of the worker or the like to the second external device. Also good.

  Here, the first external device and the second external device may be the same external device or different external devices. According to this modified example, when a disaster such as an earthquake occurs, a safety request for an operator or the like can be confirmed at any desired timing by transmitting a transmission request signal from an external device to the transmission unit.

  In addition, when the biological information transmission device determines the normal state of the worker or the like, it outputs a signal indicating the normal state of the worker or the like to the external device. The case where a signal indicating an abnormal state of a worker or the like is output has been described. However, the biological information transmission device may cause the transmission unit to transmit a signal only when the biological signal is in the normal range or in the abnormal range, and when the normal state of the worker or the like is determined and the worker The signal may be transmitted to the external device by only one when the abnormal state is determined. In this way, it may be determined whether the worker or the like is in a normal state.

  In addition, when only one of the biological signals measured by the body temperature measurement unit 20, the acceleration measurement unit 30, and the pulse measurement unit 40 deviates from the normal range, an abnormality such as a worker is determined. Explained. However, an abnormality such as a worker may be determined only when two or more of the biological signals measured by the body temperature measurement unit 20, the acceleration measurement unit 30, and the pulse measurement unit 40 deviate from the normal range. . That is, when the biological information detection unit includes a plurality of detection units, it is possible to determine normality of an operator or the like even if only one biological signal of the detection unit deviates from the normal range. When the biological signal of the detection unit deviates from the normal range, an abnormality such as an operator may be determined.

  Further, the case where the biological information detection unit includes the body temperature measurement unit 20, the acceleration measurement unit 30, and the pulse measurement unit 40 has been described. However, the biological information detection unit may be configured with only one of the body temperature measurement unit, the acceleration measurement unit, and the pulse measurement unit, or the body temperature measurement unit, the acceleration measurement unit, and the pulse measurement unit. It may be composed of two. In addition, the biological information detection unit may be configured with only a blood pressure measurement unit, or may include a blood pressure measurement unit. As described in Japanese Patent Application Laid-Open No. 7-116132, this configuration incorporates an optical pulse meter sensor and an electrocardiogram electrode into a wristwatch-type biological information transmitter attached to the wrist, and the optical pulse meter sensor This can be achieved by measuring heart rate. Since the pulse propagation time is proportional to the blood pressure, the blood pressure can be measured from the pulse propagation time.

  In addition, standard biosignals such as standard pulse, standard body temperature, standard blood pressure, and the like vary from person to person. Therefore, the biometric information transmission device may include one or more biosignal input units, for example, one or more input units among a pulse input unit, a body temperature input unit, and a blood pressure input unit. And you may enable it to input the biometric information used as the threshold value of abnormality determination by this 1 or more biosignal input part. More specifically, when the pulse input unit is described as an example, the control unit may determine the health abnormality of the worker or the like by determining that the pulse is a predetermined pulse away from the input pulse.

  Further, the determination signal may be a biological signal representing biological information itself. In addition, the biological information transmitting apparatus may not have a position specifying unit that specifies the presence position. In addition, the biological information transmission device may not have a wristwatch-type mounting unit, for example, may have a mounting unit that is attached to the skin, and any other type of mounting that can acquire other biological information. You may have a part.
