A worker's work and health status monitoring system according to an embodiment of the present invention includes a wearable device 100 , a stethoscope 200 , a mobile device 300 , and a server 400 .

The wearable device 100 may be worn on the wrist of the worker and may include a sensor for detecting the amount of exercise and the bio-signal of the worker. Specifically, the sensor for detecting the amount of exercise may include an acceleration sensor, a gyro sensor, a GPS sensor, and a barometric pressure sensor. In addition, the sensor for detecting the worker's biosignal may include a biosensor for detecting at least one of the worker's blood pressure, heart rate, body temperature, and electrocardiogram.

The stethoscope 200 is a device for measuring a worker's heart sound (hereafter heart sound) and lung sound (hereafter lung sound), and if necessary, the worker may attach and measure the heart or lungs. The stethoscope 200 is not always attached like the wearable device 100 and can measure when a measurement request message is displayed from the mobile device 300 . By measuring the heart sound and lung sound with the stethoscope 200 , it is possible to reduce the error of the biosensor and measure cardiopulmonary disease.

The wearable device 100 and the stethoscope 200 may include a short-distance communication device capable of transmitting and receiving data to and from the mobile device 300 .

Referring to FIG. 2 , measurement data of a wearable device and measurement data of a stethoscope may be checked.

As the mobile device 300 , a smartphone capable of installing an app may be used. The mobile device 300 receives the measurement signal from the wearable device 100 and the stethoscope 200 and converts it into a digital signal. It may include a mobile diagnosis unit 320 for diagnosing the working state and health state, and a communication unit for transmitting the converted digital signal and the diagnosis result.

The mobile diagnosis unit 320 compares the ECG, heart rate, and blood pressure signals measured by the biosensor of the wearable device 100 with reference values to diagnose stress intensity, labor intensity, alcohol consumption, drowsiness, and sleep quality. and diagnoses overwork by measuring the exercise amount and behavior pattern of the worker with the acceleration sensor, the gyro sensor, and the GPS sensor of the wearable device 100, and compares the heart and lung sounds measured by the stethoscope with a reference value for cardiopulmonary disease can be diagnosed The reference value may be preset and stored, and may be set as an interval range.

For example, if the heart rate and blood pressure rise from the standard value, the stress intensity is judged to increase. can do. The electrocardiogram includes a plurality of R peaks, and an RR interval (RR, time interval) may be calculated using time information at the R peak point.

The mobile diagnosis unit 320 may determine that the user is in the drinking state when the heart rate and blood pressure increase compared to the reference value but the RR interval is longer than the reference value.

The mobile diagnosis unit 320 may determine that the worker is in a drowsy state when the heart rate is lower than the reference value.

The mobile diagnosis unit 320 may determine that the quality of sleep is deteriorated when the RR interval increases in variation rate compared to the reference value and the heart rate and tongue pressure deviate from the pattern compared to the reference value repeatedly.

For example, in general, when you are drowsy, your heart rate decreases by about 10% compared to when you are in a normal state. Therefore, when the heart rate decreases by about 10% from the reference value, it may be determined that the state is drowsy.

The mobile diagnosis unit 320 may analyze the behavior pattern by moving the acceleration sensor and the gyro sensor to calculate the average moving speed and moving distance per unit time. If the behavior pattern is excessively larger than that of other workers in the same industry (more than the set value than the average), it can be judged that the labor intensity is high.

The mobile diagnosis unit 320 compares the GPS signal with the worker's work location and, if they do not match, determines that the worker is out of the work area, and may check the usual work area activity radius. In this case, the location and movement of workers can use AP (Access Point) signals in addition to GPS signals.

The mobile diagnosis unit 320 may analyze whether a fall has occurred. A fall of the worker may be detected from the signals of the gyro sensor and the acceleration sensor, and if there is no movement or limited movement for a certain period of time after the fall, it is determined as a fall and a fall signal may be transmitted to the server 400 . In the server 400 , the manager may receive the fall signal and call the worker to confirm or take immediate rescue action.

The mobile diagnosis unit 320 may determine that there is a cardiopulmonary disease when the heart sound and the lung sound show a pattern deviating from the reference value.

In the mobile device 300, reference values necessary for diagnosis and information necessary for worker authentication are stored in advance. The reference value is stored based on standard information when initially stored, but the reference value may be changed as biometric information is continuously updated.

More specifically, the mobile device 300 includes an individual biometric information storage unit 340 that stores an individual worker's medical history, normal blood pressure, heart rate, body temperature and electrocardiogram, and a facial photographed image, and the biometric information by photographing the worker. A worker authentication unit 350 for authenticating whether the worker is a worker by comparing the images stored in the storage unit, a work information storage unit 360 for storing the worker's work schedule, work location, and work range, the worker's work location and risk It may further include a map storage unit 370 for storing map information on which the region is displayed.

The mobile device 300 may establish a work schedule for workers based on the work information stored in the work information storage unit 360 and display a message when the work time comes.

In addition, the mobile device 300 determines that the wearable device 100 is not worn when the biosignal is not detected for a certain period of time or more, and displays a message of not wearing the wearable device 100 so that the worker wears the wearable device 100 . make it possible Then, the fact of non-wear is transmitted to the server 400 so that the administrator can monitor it.

In addition, the mobile device 300 compares the GPS sensor signal and map information of the worker wearable device 100 to generate a departure warning when the worker leaves the work location, and generates a danger alert when the worker enters the hazardous area. , it is possible to transmit the alarm occurrence details to the server 400 .

The work information storage unit 360 stores the average movement distance and movement speed for each work group, and the mobile diagnosis unit 320 sets the movement distance of the worker as a reference value rather than the average movement distance of the same work group stored in the work information storage unit. When it exceeds the above limit or the movement speed is faster than the reference value, a message recommending a break may be displayed and the movement distance and movement speed of the worker may be transmitted to the server 400 .

The mobile device 300, when the ECG, heart rate, and blood pressure signals measured by the biosensor of the wearable device 100 are out of reference values, sends a message to the worker to measure heart and lung sounds with the stethoscope 200 can be displayed As described above, the wearable device 100 is always worn by the worker, but the stethoscope 200 cannot be carried or worn all the time. Accordingly, when the stress intensity or labor intensity measured by the mobile diagnostic unit deviates from the reference value, the worker may be encouraged to measure the heart sound and lung sound with the stethoscope 200 .

The server 400 receives measurement signals from the wearable device 100 and the stethoscope 200 and stores the biometric information of all workers. and a doctor information storage unit 420 for allocating and storing a doctor in charge for each individual worker, and a doctor information storage unit 420 when both the measurement signal of the wearable device 100 and the measurement signal of the stethoscope 200 deviate from the reference value. ) to the doctor stored in the ), and can transmit the doctor's information and treatment guide message to the worker's mobile device 300 .

And based on the biometric information stored in the integrated biometric information storage unit 410, the stress intensity, labor intensity, drinking, articulation, sleep quality, and cardiopulmonary disease based on the worker's biometric information and behavior pattern It may further include a monitoring unit 440 that analyzes and displays the server diagnosis unit 430 to determine the biometric information and behavioral pattern changes and the diagnosis result of the diagnosis unit in time series.

Although the mobile device 300 diagnoses the working status and health status of workers, if the amount of data increases due to the characteristics of the mobile device 300 , accurate diagnosis may be difficult and errors may occur. Therefore, accuracy can be secured by receiving the measurement signal of the wearable device 100 and the measurement signal of the stethoscope 200 from the server 400 and re-diagnosing.

The server diagnosis unit 430 may diagnose stress intensity, labor intensity, drinking, drowsiness, and sleep quality using biosignals, and may diagnose labor intensity using behavior patterns. In addition, the presence of lung disease can be diagnosed by heart and lung sounds.

The server diagnosis unit 430 may transmit a message guiding treatment to the worker's mobile device 300 when it is determined that a doctor's diagnosis is necessary by synthesizing the biosignals, behavior patterns, and the diagnosis results of heart and lung sounds. . In this case, pre-stored medical institution and doctor information may be transmitted together. In the case of comprehensive judgment, if the score is higher than the standard value by simply summing the results of each judgment, it can be judged that treatment is necessary, and it can be judged by assigning weights. For example, if a worker's behavior pattern has been consistently excessively above average for the past week, the behavior pattern can be given a lot of weight. Therefore, in this case, even if the labor intensity is not high in terms of biosignals, the behavioral patterns give a lot of weight to recommend a diagnosis by a doctor.

The server 400 may further include an algorithm updater.

The algorithm update unit may update the diagnostic algorithm based on individual biosignals and behavior patterns of workers. For example, at the time of initial diagnosis, work status or health status is diagnosed with standardized heart rate or blood pressure, but since bio-signals can be individually different, the algorithm can be updated by changing the standard value based on the measured bio-signals and behavior patterns. have.

The server 400 transmits the updated algorithm to the mobile device 300 , and the mobile device 300 receives it and can diagnose the working state and health state with an algorithm optimized for each individual worker.

With the above configuration, it is possible to not only monitor the working status of the workers at the industrial site, but also to check the health status to prevent accidents such as overwork in advance.

In particular, when stress intensity or labor intensity increases, or when cardiopulmonary disease is suspected, it is possible to prevent disease and accidents by recommending medical treatment to a doctor.

In the above, the embodiment has been mainly described, but this is only an example and does not limit the present invention, and those of ordinary skill in the art to which the present invention pertains are not exemplified above in the range that does not depart from the essential characteristics of the present embodiment. It can be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiment can be implemented by modification. And differences related to such modifications and applications should be construed as being included in the scope of the present invention defined in the appended claims.
