1 is a diagram illustrating a sensor information management system according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the sensor information management system may include a mobile terminal 100 and a server 200.

The portable terminal 100 may continuously collect sensor information through a sensor unit (not shown) including at least one sensor and utilize the collected sensor information. For example, the portable terminal 100 may continuously collect at least one of the surrounding environment information and the user state information (hereinafter, sensor information) through a plurality of sensors. Thereafter, the mobile terminal 100 may analyze the collected sensor information and provide an alarm (eg, an alarm for a health risk situation to the user) when the preset alarm condition is satisfied. In this case, the portable terminal 100 may provide the alarm by analyzing sensor information collected for a predetermined period of time. In addition, the portable terminal 100 may calculate a correction value of the sensor based on the collected sensor information, and correct the sensing value by using the calculated correction value to provide an accurate sensing value.

The mobile terminal 100 according to the present invention is a low-power processor (eg MCU (Microcontroller) for collecting the sensor information, in addition to the main processor (for example, CPU (Central Processing Unit), AP (Application Processor), etc.) for controlling the overall operation A controller unit (MPU) and a microprocessor unit (MPU) may be separately provided. This is to continuously collect sensor information by minimizing current consumption of the mobile terminal 100. That is, the mobile terminal 100 according to the present invention maintains a main processor (hereinafter, referred to as a main controller) that consumes a relatively large amount of current in a sleep state and uses sensor information through a low power processor (hereinafter referred to as a sub-controller) that consumes less current. Can be collected continuously.

In addition, the portable terminal 100 stores the collected sensor information in an internal memory (hereinafter referred to as a sub storage unit) included in a sub controller in a sleep state, and main storage unit in a wake-up state. Can be stored in Meanwhile, when the storage space of the sub storage unit is insufficient in the sleep state, the sub controller may wake up the main controller and move and store sensor information stored in the sub storage unit to the main storage unit. Alternatively, when the storage space of the sub storage unit is insufficient, the portable terminal 100 may delete the sensor information stored the longest of the sensor information stored in the sub storage unit and store the collected sensor information in the sub storage unit. have.

The portable terminal 100 may analyze the collected sensor information and provide an alarm when a preset alarm condition is satisfied. For example, the alarm condition may be a reference condition for determining whether the user's health condition is deteriorated or whether the user may be in an environment that may be dangerous or may adversely affect the user's health. The alarm condition may include surrounding environment information such as temperature, humidity, air pressure, ultraviolet ray, radioactivity, carbon dioxide, environmentally harmful substances, or user state information such as movement, body temperature, electrocardiogram, blood pressure, blood glucose level, and the like. For example, the alarm condition may be a hypothermia-induced environment in which a temperature below a certain level (eg, 0 degrees Celsius or less) is maintained for a certain time (eg, 1 hour), or a seasonal cold having a difference of a maximum temperature and a minimum temperature for a day or more. Includes the causative environment, the cooling-causing environment where the temperature difference between the outside temperature is maintained at a certain value (for example, 8 degrees) or more for a certain time (for example, 2 hours), the average amount of movement per day, week, month, and year, and the amount of UV exposure per minute / hour. can do. The alarm condition may be classified into a first alarm condition and a second alarm condition.

The first alarm condition is stored in a sub storage unit and used for alarm notification by the sub controller. The first alarm condition is a reference condition for sensing information collected for a relatively short period (eg, several minutes to several hours). This is due to a performance limitation of the sub controller which is driven at low power. For example, the first alarm condition may include a hypothermia-inducing environment, a cooling disease-inducing environment, and a UV exposure amount.

The second alarm condition is stored in the main storage unit and used for alarm notification by the main control unit. The second alarm condition is a reference condition for sensing information collected for a relatively long period (eg, day or month). For example, the second alarm condition may include a daily / weekly / monthly average moving amount.

The portable terminal 100 may provide an alarm through a warning message output and a warning sound output informing a user of a health risk. Alternatively, the portable terminal 100 may provide an alarm by transmitting an emergency call or emergency message to a predetermined contact (emergency rescue team, doctor, friend, etc.).

The portable terminal 100 may correct the measurement error of the sensor based on the collected sensor information. For example, the mobile terminal 100 checks the change of the sensor value based on the collected sensor information, calculates a compensation value through the change of the sensor value, and measures the sensor using the calculated compensation value. The error can be corrected.

In addition, the mobile terminal 100 may control peripheral devices (eg, air conditioners, heaters, humidifiers, boilers, etc.) connected wirelessly (eg, home networks). For example, the portable terminal 100 increases the room temperature by controlling the air conditioner when the room temperature is maintained at 26 degrees Celsius or less for 1 hour or more in summer, and the air conditioner is maintained when the room temperature is maintained at 30 degrees or more for 1 hour or more. It can be controlled to reduce the room temperature. Or, if the room temperature is maintained at 18 degrees Celsius or less for 1 hour or more in winter, the mobile terminal 100 increases the room temperature by controlling the temperature of the heater or boiler, and is maintained for more than 1 hour or more at 23 degrees Celsius The heater or boiler can be controlled to reduce the room temperature. Similarly, the portable terminal 100 may control the humidifier to properly maintain the humidity.

The portable terminal 100 may transmit the collected sensor information to a preset server 200 and receive an alarm message from the server 200. Alternatively, the mobile terminal 100 may update the pre-stored alarm condition by receiving an alarm condition optimized from the server 200 according to the health state of the user.

The server 200 receives and stores sensor information, analyzes sensor information, and provides an analysis result to the mobile terminal 100. In detail, the server 200 receives and stores sensor information from the mobile terminal 100 at predetermined intervals. The server 200 may analyze the stored sensor information and generate an alarm message and transmit the generated alarm message to the mobile terminal 100 when the preset third alarm condition is satisfied. For example, when the present invention is utilized for health care, the server 200 may be a server of a hospital designated by a user, a health care center operated by a national institution, and the like, and the alarm message may include medical information and first aid. Method, location of nearby hospital or pharmacy, referral exercise, referral food, warning message, and the like.

In addition, the server 200 stores the collected sensor information for each user by DB (DataBase), and based on the DB for each user, an alarm condition (first alarm condition and second alarm condition) optimized for a user's health state. It may be generated and provided to the mobile terminal 100. Meanwhile, in the case of a patient requiring continuous management, the doctor in charge may check sensor information of the patient stored in the server 200 and transmit an alarm message when an action is required.

Can be. The sensor unit 170 may transmit sensor values corresponding to the surroundings and states of the portable terminal 100 to the sub controller 140 in the sleep mode and the activation mode. That is, the sensor unit 170 may be driven by the low power sub-controller 140 even when the portable terminal 100 enters the sleep mode to collect surrounding situation and state information.

Meanwhile, although the sensor unit 170 is illustrated as being connected to the sub controller 140 in FIG. 2, the present invention is not limited thereto.

It further includes (not shown).

The sub controller 140 may control the driving of the sensor unit 170. The sub controller 140 may be formed of a microprocessor unit (MPU), a micro control unit (MCU), or the like, which is a low power processor. For example, the sub controller 140 may collect temperature, humidity, ultraviolet light, motion, air pressure, body temperature, blood pressure, electrocardiogram, radiation, environmental substances, and the like through the sensor unit 170.

The sub controller 140 may include a sub storage unit 141 for storing the collected sensor information. As the collected information is stored in the sub storage unit 141, the sleep state of the main controller 110, which consumes a large amount of current, may be maintained. When the storage space of the sub storage unit 141 is insufficient, the sub controller 140 may transmit a wake-up signal to the main controller 110. That is, the sub controller 140 wakes up the main controller 110 when the storage space of the sub storage unit 141 is insufficient to move the sensor information stored in the sub storage unit 141 to the main storage unit 120.

The sub controller 140 may determine whether the main controller 110 is in the sleep mode in step 303. If the main controller 110 is not in the sleep mode, the sub controller 140 proceeds to step 313 described later. On the other hand, when the main controller 110 is in the sleep mode, the sub controller 140 proceeds to step 305 to check the storage space of the sub storage unit 141, and the sensor information collected in step 307 to the sub storage unit. It is possible to check whether the data can be stored at 141. When the collected sensor information can be stored in the sub storage unit 141, the sub control unit 140 proceeds to step 309 to store the collected sensor information in the sub storage unit 141 and returns to step 301. have. On the other hand, if the collected sensor information cannot be stored in the sub storage unit 141, the sub control unit 140 may proceed to step 311 to wake up the main control unit 110.

Next, the wake-up main controller 110 may store the collected sensor information in the main storage 120 in step 313. In this case, the sub controller 140 may move the sensor information stored in the sub storage unit 141 to the main storage unit 120.

When the movement of the sensor information is completed, the sub control unit 140 may proceed to step 301 to repeat the above process. At this time, the main controller 110 enters the sleep state.

In FIG. 3A, the sub-controller 1440 collects sensor information regardless of whether the sleep mode is present. However, embodiments of the present invention are not limited thereto. For example, when the sensor unit 170 is switchable between the main control unit 110 or the sub control unit 140 through a switch (not shown), the main control unit 110 collects sensor information in an activation mode, The sub controller 140 may collect the sensor information in the sleep mode.

As described above, the embodiment of the present invention maintains the main control unit 110 having a large current consumption in a sleep state, and collects sensor information through the sub control unit 140 having low current consumption. Can be minimized. For this reason, an embodiment of the present invention can continuously collect sensor information for a long time. On the contrary, the conventional portable terminal cannot collect sensor information continuously due to large current consumption.

3B is a flowchart illustrating a sensor information collection method of a mobile terminal according to another embodiment of the present invention.

1 to 3B, the portable terminal 100 according to another embodiment of the present invention may enter a sleep mode in step 331. The sleep mode may be entered when there is no input for a predetermined time (for example, 30 seconds) or when a user requests.

When the portable terminal 100 enters the sleep mode, the sub controller 140 may collect sensor information in step 333. The sensor information is collected through the sensor unit 170 connected to the sub controller 140. As described above, the sensor unit 170 may include a plurality of sensors for recognizing surrounding environment information and user state information. The plurality of sensors may operate periodically in consideration of current consumption. At this time, the operation period of each sensor may be set differently. For example, the ultraviolet sensor may have an operating cycle of several seconds to several minutes, and the temperature sensor and the humidity sensor may have an operating cycle of several minutes to several ten minutes.

The sub-controller 140 may check the storage space of the sub-storage unit 141 in step 335 and check whether the sensor information collected in step 337 can be stored in the sub-storage unit 141. If the sensor information collected in step 337 can be stored in the sub storage unit 141, the sub control unit 140 proceeds to step 339 and stores the collected sensor information in the sub storage unit 141, which will be described later. Proceed to step 345.

On the other hand, if the sensor information collected in step 337 cannot be stored in the sub storage unit 141, for example, when the storage space of the sub storage unit 141 is insufficient, the sub controller 140 proceeds to step 341. The storage space may be secured by deleting at least some of the sensor information stored in the sub storage unit 141. For example, the sub controller 140 may delete the oldest sensor information and recheck the storage space. That is, the sub-controller 140 may delete the sensor information having the oldest storage order one by one until a storage space for storing the collected sensor information is secured.

Alternatively, the sub controller 140 may delete sensor information stored in the sub storage unit 141 based on a preset size (for example, 5 MB). For example, the sub-controller 140 may delete a plurality of pieces of sensor information having an old storage order so that a storage space is 5 MB or more.

Alternatively, the sub controller 140 may delete sensor information stored in the sub storage unit 141 based on a predetermined time. For example, the sub controller 140 may delete sensor information having a time difference of 2 minutes based on the oldest sensor information.

Alternatively, the sub controller 140 may check the size of the collected sensor information and delete old sensor information so that a storage space corresponding to the size of the checked sensor information is secured.

The sub controller 140 may store the collected sensor information in the secured storage space in step 343. In operation 345, the sub controller 140 may check whether the main controller 110 wakes up. The main controller 110 may wake up by an external event such as a call reception, a text message reception, an alarm, a physical key input, or the like.

When the main controller 110 does not wake up in step 345, the sub controller 140 may return to step 333 and repeat the above-described process. On the other hand, when the main controller 110 wakes up in step 345, the sub controller 140 proceeds to step 347 to move and store sensor information stored in the sub storage unit 141 to the main storage unit 120. Can be.

Such another embodiment of the present invention can reduce the time that the main control unit 110 wakes up unnecessarily. For example, even if the storage space is insufficient in the sub storage unit 141, the main control unit 110 may wait until the main control unit 110 wakes up by the external event without waking up the main control unit 110. As such, by preventing unnecessary wake-up of the main controller 110, another embodiment of the present invention can further reduce current consumption. Such another embodiment of the present invention may be useful when the sensor information after a predetermined time is meaningless. For example, if it is assumed that a compensation value is calculated using only sensor information for a predetermined time (for example, 15 minutes), rather than moving and storing sensor information to the main storage unit 120 as in an embodiment of the present invention. As in another embodiment of the present invention, it may be useful to delete and store old sensor information.

4 is a flowchart illustrating an alarm notification method of a portable terminal according to an exemplary embodiment of the present invention. Hereinafter, a case where the mobile terminal is in a sleep state will be described as an example.

1 to 4, the sub-controller 140 according to an exemplary embodiment of the present disclosure may periodically collect sensor information in step 401. Here, since the detailed description of the sensor information collection has been described above with reference to FIGS. 3A and 3B, it will be omitted.

The sub-controller 140 may analyze the sensor information in step 403, and check whether the first alarm condition is satisfied in step 405. If the analysis result of the sensor information does not satisfy the first alarm condition, the sub controller 140 may return to step 401 and repeat the above-described process. On the other hand, when the analysis result of the sensor information satisfies the first alarm condition, the sub-controller 140 may wake up the main controller 110 in step 407.

The wake-up main controller 110 may notify the alarm in step 409. The alarm notification may be a warning message and / or a warning sound output informing of a dangerous situation such as ultraviolet exposure, hypothermia, cooling sickness and the like. Alternatively, the alarm notification may be an emergency call or emergency message transmission request to a predetermined contact (emergency rescue team, hospital, doctor, friend, etc.).

Meanwhile, the main controller 110 may control peripheral devices (eg, air conditioners, heaters, humidifiers, boilers, etc.) that are wirelessly connected (eg, home networks). For example, the mobile terminal 100 increases the room temperature by controlling the air conditioner when the room temperature is maintained at 26 degrees Celsius or less for 1 hour or more in summer, and increases the room temperature by 1 hour or more at 30 degrees Celsius or more. The air conditioner can be controlled to reduce. Alternatively, when the room temperature is maintained at 18 degrees Celsius or less for 1 hour or more in winter, the portable terminal 100 increases the room temperature, and when the temperature is maintained at 23 degrees Celsius or more for 1 hour or more, the heater or The boiler can be controlled. Similarly, the portable terminal 100 may control the humidifier to properly maintain the humidity.

In addition, the sub-controller 140 analyzes the collected sensor information in the sleep state, and compares the alarm with the first alarm condition. However, the present invention is not limited thereto. That is, the sub controller 140 has limited performance due to the low power design. In addition, the amount of sensor information stored in the sub storage unit 141 may also be limited. Therefore, in the present invention, when a complicated operation is required, such as analyzing sensor information for a long time (for example, one day, one week), the main controller 110 analyzes the sensor information stored in the main storage unit 120 at regular intervals. An alarm may be notified when the analysis result satisfies the second alarm condition by comparing the analysis result with the second alarm condition. In this case, if the main controller 110 is in a sleep state at the time when analysis of sensor information requiring a complicated operation is required, the main controller 110 may be woken up. On the other hand, when analyzing the sensor information for a very long time (for example, one month, one year), or if a very complex calculation is required, the analysis and alarm of the sensor information may be performed by the server 200. That is, the server 200 analyzes the sensor information received from the mobile terminal 100 at predetermined intervals, compares the analysis result with a third alarm condition, and the analysis result satisfies the third alarm condition. An alarm message may be generated and transmitted to the mobile terminal 100.

Meanwhile, in FIG. 4, the alarm is notified using the collected sensor information. However, in another example of the present invention, the collected sensor information may be used to correct the measured value of the sensor. For example, in the case of providing the external temperature and / or humidity measurement function, when the portable terminal 100 is used for a long time, heat is generated. For this reason, the portable terminal 100 cannot measure the accurate external temperature and / or humidity. Accordingly, another embodiment of the present invention calculates a compensation value based on the collected sensor information (temperature and / or humidity), and compensates the value measured by the temperature and humidity sensor with the calculated compensation value to accurately measure the measurement. Can provide results.

5 is a flowchart illustrating a sensor information collection and alarm notification method of a sensor information management system according to an exemplary embodiment of the present invention.

1 to 5, the portable terminal 100 may collect sensor information in step 501. Here, the detailed description of the sensor information collection has been described above with reference to FIGS. 3A and 3B and will be omitted.

The portable terminal 100 may transmit the sensor information collected in step 503 to the server 200. The transmission of such sensor information may be performed periodically. In this case, the server 200 may be a server operated in a hospital designated by a user, a server of a health care center operated by a national institution, a personal server, or the like. In this way, the collected sensor information is transmitted to the server 200 because the performance (information processing capability, storage space) of the mobile terminal 100 is limited. For example, the mobile terminal 100 may not have enough storage space to store sensor information collected for more than one year. In addition, due to performance limitations of the main controller 110 of the portable terminal 100, it may be difficult to analyze sensor information collected for one year or more.

Next, the portable terminal 100 analyzes sensor information in step 505, and determines whether the analysis result of the sensor information satisfies a preset alarm condition (a first alarm condition or a second alarm condition) in step 507. . If the alarm condition (including the first alarm condition or the second alarm condition) is not satisfied, the portable terminal 100 may return to step 501 and repeat the above-described process. As described above, the sensor information may be analyzed by the sub controller 140 using the first alarm condition or by the main controller 110 using the second alarm condition. On the other hand, when the alarm condition (first alarm condition or second alarm condition) is satisfied, the portable terminal 100 may notify the alarm in step 509. Here, since the detailed description of the alarm notification has been described above, it will be omitted.

In operation 511, the server 200 may analyze sensor information transmitted from the mobile terminal 100, and determine whether the third alarm condition is satisfied in operation 513. If the third alarm condition is not satisfied, the server 200 may return to step 511 and repeat the above-described process. The server 200 may analyze sensor information at predetermined intervals. On the other hand, if the third alarm condition is satisfied, the server 200 proceeds to step 515 to generate an alarm message, and transmits the generated alarm message to the mobile terminal 100 in step 517. The alarm message may include medical information, first aid method, recommended food, recommended exercise, location of a nearest hospital or pharmacy, and the like, which help the user's health state.

The present invention described above can be utilized in various ways. For example, the present invention may use the ultraviolet (UltraViolet-ray: UV) sensor mounted on the portable terminal 100 when the mountain climbing to alarm the ultraviolet exposure. In detail, the sub control unit 140 periodically drives the ultraviolet sensor to store the sensing value in the sub storage unit 141, and when the ultraviolet value continuously exceeds the dangerous value, the sub control unit 140 operates for the alarm. Wake up. The wake-up main controller 110 may output a warning message and / or a warning sound for recommending that the user refrain from outdoor activities or cover the skin because the UV exposure index is dangerous. In this case, it is preferable that the user exposes the portable terminal 100 to the outside in order to measure ultraviolet rays. The sensing period of the ultraviolet sensor may be set to several seconds to several minutes by the user.

In addition, the present invention can be utilized to alarm the change of season cold. In detail, the mobile terminal 100 may analyze the sensor information collected through the temperature sensor and the humidity sensor to check whether the environment is susceptible to cold, and inform the user of the result. That is, when the difference between the maximum temperature and the minimum temperature is large and the low temperature is maintained during the day, the portable terminal 100 may output a warning message to warn the user because the user is exposed to an environment prone to a cold season. As such, since the portable terminal 100 is almost always located around the user, the portable terminal 100 may collect information about the environment around the user more accurately and objectively, and provide health information accordingly.

In addition, the present invention can be utilized in the hypothermia notification system. In detail, the portable terminal 100 may collect and store the ambient temperature periodically (eg, several minutes) through a temperature sensor. Subsequently, the mobile terminal 100 analyzes sensor information at regular intervals and outputs a warning sound indicating a hypothermia-induced environment when the temperature below 0 degrees Celsius is maintained for 1 hour or more, or by flashing a light (display or camera flash). You can notify the alarm. Alternatively, the mobile terminal 100 may transmit an emergency call or emergency message to a preset contact (emergency rescue team, emergency center or friend). In this case, the mobile terminal 100 may measure the current location and transmit the location information together.

In addition, the present invention can be utilized in a cooling bottle prevention system. In detail, the portable terminal 100 periodically measures the temperature through a temperature sensor and stores the temperature. At this time, the portable terminal 100 measures and stores the temperature in the unit of minutes or tens of minutes through the sub-control unit 140 and the temperature sensor even in the sleep state, and the main control unit 110 stores the unit of 1 hour or 2 hours. As a result of the wake-up, the temperature information collected through the sub-controller 140 may be analyzed. As a result of the analysis, when the temperature is maintained for 3 hours or more and 20 degrees or less, the main controller 110 may alert the user of the cooling bottle warning, and if the temperature is maintained for 5 hours or more, may alarm the cooling bottle warning. At this time, if the portable terminal 100 is interlocked with the air conditioner through a wireless connection (home network system), the portable terminal 100 can automatically control the temperature of the air conditioner to prevent the cooling bottle.

In addition, the present invention can be utilized in a patient management system. In detail, the server of the hospital may periodically receive and store sensing information from the portable terminal 100 of the patient in need of continuous health care. In this case, the attending physician may check the health state of the patient through the stored sensing information. That is, the attending physician can continuously monitor the patient's condition. For example, if the patient is exposed to a dry environment, the attending physician may recommend that the patient take appropriate action by calling or sending a message. Or, if the patient's movement is measured by the motion sensor among the sensing information transmitted from the patient that requires regular exercise, and the patient's movement is insufficient (for example, if there is little movement or little moving line during the day) The attending physician may recommend walking exercises through phone calls or sending messages.

In addition, the present invention can be used to measure environmental information. In detail, the mobile terminal 100 may collect and store sensor information, and periodically transmit the collected sensor information to a national agency in charge of the health of the public such as a health care center. The health care center may receive the sensing information collected from the mobile terminals of the citizens and analyze the health state of the region. For example, the health care center can quantitatively collect trends of overall movements of the people, infer people's behavior patterns through long-term accumulated information analysis, and devise appropriate policies. Alternatively, the health care center may separately analyze the collected sensing information to notify the health risk information by telephone or a message to a user who detects a health abnormality or is frequently exposed to an unhealthy environment.

In addition, the present invention can be utilized for personal life pattern management. In detail, the mobile terminal 100 may collect and analyze sensing information for a long time (for example, one year) and provide health information according to a user's life pattern. For example, when the user lives in an average dry environment, the mobile terminal 100 or the server 200 may notify the user that the environment is not suitable for a respiratory disease and provide an appropriate measure. Alternatively, the portable terminal 100 or the server 200 may recommend medical information, vitamin D-rich foods, etc. that vitamin D may be insufficient due to lack of going out when there is no ultraviolet ray detection for a long time. As such, the sensor information collected over a long period of time may be stored in the main storage of the portable terminal, or may be periodically transmitted to and managed by a designated server.

The sensor information management method of the portable terminal according to the embodiment of the present invention as described above may be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer-readable recording medium. In this case, the computer-readable recording medium may include a program command, a data file, a data structure, etc. alone or in combination. Meanwhile, the program instructions recorded on the recording medium may be those specially designed and configured for the present invention, or may be known and available to those skilled in computer software. The computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs, DVDs, and magnetic disks, such as floppy disks. -Magneto-Optical Media, and hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like. The program instructions also include high-level language code that can be executed by a computer using an interpreter as well as machine code such as produced by a compiler.
