Description

[0001] The present invention relates to a method for transmitting emergency information of a user and an alarming sleep time,

In particular, the present invention relates to an emergency information transmission and alarm method, and more particularly, it relates to an emergency information transmission and alarm method, in which an urgent state of a user situation is determined according to a comparison between a measured value of a user's biomedical signal and a previously stored health reference value, Alarm is sent only when the emergency call request signal is sent to the contact and the user's momentum measurement value that is performed for a predetermined time after the alarm is alarmed exceeds the predetermined momentum amount when the predetermined target sleep time or alarm time is reached To an emergency information transmission and a sleep time alarm method of a user.

Recently, as the elderly population increases, the demand for medical services increases, and the importance of acquiring and managing medical information is gradually increasing.

Ubiquitous healthcare (u-health) services are becoming increasingly important due to these changes in social awareness, and systems and equipment are being developed to realize this.

In addition, the development of semiconductor technology has made it possible to easily use a living body signal measuring device capable of measuring basic body information such as body temperature, blood sugar, blood pressure, body fat and electrocardiogram at home.

In particular, in recent years, a technique has been proposed in which a user-specific health standard value is set in advance, and information corresponding to the emergency level can be measured and read more precisely.

Parties exposed to various risk situations such as emergencies, natural disasters and crime situations can use various communication means such as cellular phone, PDA and smart phone to contact the relief management system used by various relief management centers to inform their situation have.

When the relief communication of the user of the portable terminal is received in the relief management system used in the fire department or the police station, the risk situation can be solved by being sent to the site to rescue the victim at the relief management center.

However, such a conventional relief request method has a problem that a victim in a dangerous situation is difficult to convey accurate information because a victim explains his / her position in words or a character described in a text message or the like, so that a long time can be consumed .

In addition, the relief management center may not be able to find the right place by mistakenly understanding the place where the dangerous situation occurred, and therefore may not be able to cope with the danger quickly.

At this time, if the victim is exposed to a dangerous situation for a long time, it can be fatal to the life of the victim. Inevitably, if the person is moved, the person should be contacted from time to time. Therefore, the person in danger is injured, There was a limitation that the request for relief might become impossible.

Meanwhile, the alarm function among the additional functions of the mobile terminal is provided for most of the wireless communication terminals at present.

However, the alarm function according to the prior art is not different from the alarm clock, and if the function is enhanced, the melody can be set by the user and the time of the alarm setting can be managed as a plurality of lists.

If a user specifies a specific time when the alarm function is set, information about the specific time is stored in the memory, and the internal timer of the electronic device such as a handset is operated to compare the time information of the electronic device with the alarm setting time stored in the memory The alarm function is activated.

In addition, the morning call function of the portable terminal is a function that allows the user who is sleeping to wake up when the user sets a desired time to wake up and is informed by a bell sound, vibration, or the like at the set time.

However, the conventional morning call function allows the user to detect that the alarm time is set by a bell sound or vibration. When the user inputs a simple key (an end key) or opens and closes a folder, the set morning call function is released.

Since the morning call function is easily canceled in this way, the user sets up the morning call in a predetermined time interval. However, when the end key is input, the morning call can be released again so that the user can sleep again after releasing the morning call. .

FIG. 3 is a block diagram of the main screen displayed on the display unit 160 of the bio-signal measuring device 100 shown in FIG. 2, and includes a bio-signal, an alarm setting, and a convenience function.

4 is a flowchart illustrating an operation of the emergency information transmission method of the user according to the first embodiment of the present invention.

The operation of the emergency information transmission method of the user according to the first embodiment of the present invention will now be described with reference to FIGS. 1 to 4. FIG.

First, the emergency relief service applicant subscribes to the emergency relief service including health care, and registers the individual detail information including the service user health standard value in the control server 400 of the control center 300.

After the registration process, the respiration phase corresponding to the user health reference value and the health reference value is stored in the bio-signal measuring device 100 (S110).

Specifically, the user sets the bio-signal reference value of the user by storing the normal state or emergency state for each predetermined health reference value in the database 120 of the bio-electrical signal measuring device 100 according to his / her health state.

The bio-signal measuring device 100 is synchronized with the user's portable terminal 200 (S120) and a plurality of third-party terminals 500_1, 500_2, ..., 500_n such as family members, friends and acquaintances, 700 and the medical institution terminal 800 are set (S130).

The bio-signal measuring device 100 measures a bio-signal in contact with a user's body (S140), compares the bio-signal measurement value with a health reference value for each user, and when the user is in an emergency situation, do.

The detailed operation of the bio-signal measuring device 100 will be described below.

The control unit 110 outputs a control signal to the bio-signal sensor 130 to measure a predetermined bio-signal, and transmits the bio-signal measurement value to the portable terminal 200 through the communication unit 140 according to the set period.

In addition, the current state of the user of the bio-signal measuring device 100 is determined by comparing the bio-signal measurement value with a user-specific health reference value stored in the database 120 in operation S150.

Unlike a conventional bio-signal measuring terminal that simply measures a bio-signal and transmits it to a control center or the like, the bio-signal measuring device 100 according to the present invention transmits a bio-signal measured through the bio-signal sensor 130 to a predetermined threshold The user can directly determine the emergency situation by comparing with the range of values.

If the bio-signal measurement value is within the health reference value range for each user, that is, exceeds the upper limit value or is less than the lower limit value, the control unit 110 determines that the user's emergency condition is present (S160).

In particular, the health reference value stored in the database 120 included in the bio-signal measuring device 100 according to the present invention is not a simple user's biometric signal information but a normal state and an emergency state according to the user's own biometric information Data entered in one state.

For example, the normal range of pulse rate of an adult with a healthy condition is 60 to 80 times / minute. However, if the pulse rate is less than 40 per minute, if the pulse strength and interval are both irregular, if the pulse falls every second or third, if the pulse is not measured at all for a few seconds, In the case of a child, if the above-mentioned 60 to 80 times / minute is fixed to a normal pulse value, the emergency situation may not be accurately determined for each user.

Therefore, when the measured pulse rate value of a person having an average pulse rate of 50 times / minute is 45 to 55 times per minute, it is preferable that the pulse rate is judged to be normal rather than judged as an emergency state.

In order to provide the user-customized service in consideration of the health state of the user, the user of the bio-signal measuring device 100 transmits the bio-signal to the user through the database 120 of the bio- It is preferable to set it to the steady state or the emergency state.

For example, a person having an average pulse rate of 50 per minute can set the pulse rate to 45 to 55 pulses per minute to a steady state, and set the pulse rate to 40 or less per minute or 70 or more per minute to an emergency state.

Here, the pulse rate is the number of heartbeats per unit time, generally expressed in beats per minute (BPM).

That is, when a person having a pulse rate lower than a normal normal pulse rate, which is known medically, is set as described above and stored in the database 120, a personalized emergency relief service considering his / her health condition is stored in the biometric terminal 100 of the present invention It will be available through.

Although the above-described example has been described with respect to the pulse rate, it may be applied to general bio-signals, that is, blood pressure, electrocardiogram, body temperature, blood glucose level, and the like.

For example, a person with an average body temperature of 36.5 degrees can set a body temperature of 35 to 38 degrees to a steady state, and set an emergency state to 33 degrees or more or 40 degrees or more.

Accordingly, the controller 110 compares the bio-signal measurement value with the health reference value stored in the database 120 to determine whether the bio-signal measurement value is normal or emergency according to a user-set reference.

Here, the current status of the user can be divided into two levels, i.e., a normal state or an emergency state. This is an exemplary one, and various emergency stages may be set and input according to the health state of the user and the type of the biological signal.

The bio-signal sensor 130 can measure various bio-signals such as pulse, electrocardiogram, blood pressure, blood sugar, respiration signal, and body temperature, and also can measure complex signals of the bio-signals.

The bio-signal sensor 130 is generally configured to be in contact with a user's body, measures the bio-signal of the user, and transmits the measured bio-signal to the controller 110.

The bio-signal measuring apparatus 100 according to the present invention includes a communication unit 140 and transmits a bio-signal measurement value measured by the bio-signal sensor 130 to the user's portable terminal 200, Data.

The close range communication may include one of ZigBee, infrared communication, or Bluetooth.

Since the bio-signal measuring device 100 according to the present invention is generally structured to be in contact with a user's body, the bio-signal measuring device 100 is configured to be small in size so as not to significantly affect transmission and reception of radio waves, Can be used.

Particularly, in the case of a wristwatch type, it is constituted of a stretch type such as a rubber band, a bulk type, and the like, so that it can be worn naturally without a sense of discomfort of the user.

If the measurement value of the bio-signal is outside the health reference value range in step S150, the controller 110 determines that the user is in an emergency state, which is not a normal state, in step S160. (S170), and transmits the measurement result including the biological signal measurement result and the severity determination result to the portable terminal 200 (S180).

At this time, the emergency contact pop-up unit 150 displays the third-party terminals 500_1, 500_2, ..., and the like, which are previously set in the bio-signal measuring device 100 synchronized with the user's portable terminal 200, 500_n and the medical institution terminal 800 are automatically popped up and displayed on the display unit 160 (S190).

When the user touches the screen of the contact selected from the emergency contacts displayed on the display unit 160 of the bio-signal meter 100 (S195), the emergency relief request signal and the GPS position information are transmitted to the selected contact (S197).

Meanwhile, the portable terminal 200 sends the measurement result to the control server 400 and stores the measurement result in the database 120 of the control server 400.

At this time, when the situation information of the user is received from the bio-signal measuring device 100, the control center 300 can quickly grasp the position of the user using the received GPS position information and perform an emergency relief service (S200).

Meanwhile, it is preferable that the GPS position information of the user is received by the GPS receiving unit built in the portable terminal 200 of the user. However, in case that the GPS position information is not received, the GPS unit 70 built in the bio- The bio-signal measuring device 100 automatically transmits the position information or the movement path of the user to the control center 300 through the portable terminal 200 in the situation.

In addition, the portable terminal 200 transmits the measured bio-signal value measured by the bio-signal measuring device 100 to the control server 400 of the control center 300 and the third-party terminals 500_1, 500_2,..., 500_n to notify the user's family, friends, acquaintances, etc., as well as the control center 300 that supervises the emergency relief.

The control center 300 receives the user's biometric signal measurement value and the emergency degree determination result from the portable terminal 200 and informs the emergency rescue institution terminal 700 and the medical institution terminal 800 of the emergency status to provide an emergency relief service .

Here, the emergency rescue organization includes 119 general situation rooms operated by the Small and Medium Enterprise Emergency Management Agency, and an emergency service center in each area.

If the bio-signal measurement value is within the health reference value range in step S150, the controller 110 determines that the user status is normal (S165). If the bio-signal measurement value is not within the health reference value range, The portable terminal 200 transmits the measurement result to the control server 400 through the communication unit 140 of the bio-signal terminal 100 to the user's portable terminal 200 (S175) The service details are stored in the control server 400 (S177).

In addition, the user's bio-signal measurement value and the severity determination result are stored in the database 120 of the control server 400 together with a predetermined user identification code, and a warning message informing the degree of urgency is also stored by the user of the bio- Stored in the received service description, and the user can access the control server 400 so that the user can confirm the service history provided by the user.

5 is a flow chart illustrating the operation of the sleep time alarm method according to the second embodiment of the present invention.

The operation of the sleep time alarm method according to the second embodiment of the present invention will be described with reference to FIGS. 1 to 3 and FIG.

When the target sleep time and the alarm time are input through the input of the user's key input unit 50 in step S210, the control unit 110 sets a predetermined amount of exercise necessary for the alarm cancellation and stores the predetermined amount of exercise in the storage unit 180 (S220) .

When the user inputs a sleep start time through the key input unit 50 at step S230, the controller 110 senses the sleep start time and stores the input alarm time, the sleep start time, and the set exercise amount in the storage unit 180. [

The exercise amount may be a walking amount for a predetermined time or a body movement amount for releasing a set alarm.

The sleep start time may be input using a sleep key provided separately to the key input unit 50. [

That is, when the user presses the sleep key provided separately in the key input unit 50 during the alarm mode in the bio-signal measuring device 100, the control unit 110 detects the input of the sleep start time and notifies the sleep time of the sleep key to the sleep start time Time.

The control unit 110 calculates the sleep time until the set alarm time.

In other words, when the sleeping start time, for example, 12:00, is set, the controller 110 calculates the time from the sleep start time to the set alarm time, for example, 6:00, and recognizes that the calculated time is the sleeping time.

The control unit 110 compares the calculated sleep time with the target sleep time, for example, 7 hours (S240).

(S245) whether the current time is the set alarm time even if the user has started sleeping and has reached the target sleeping time of 7 hours or has not reached the target sleeping time yet.

If the current time reaches 6 o'clock, which is the predetermined alarm time, the control unit 110 commands an alarm alarm (S250), and the alarm unit 190 alerts the alarm in response to the alarm (S260).

Methods for alarming the alarm include bell sound, vibration, and the like.

The acceleration sensor 170 measures a user's amount of exercise performed within a predetermined time, that is, 4 to 6 minutes, preferably 5 minutes, after the alarm is activated (S270).

If it is determined in step S280 that the amount of exercise measured by walking or body movement has exceeded a predetermined amount of exercise, the control unit 110 recognizes that the user has awakened to the normal state ), An alarm alarm stop is commanded (S300), the alarm is stopped, and then the exercise amount processing information generated when performing the exercise amount is stored in the storage unit 180. [

If the user does not get up and can not walk or can not get out of bed, and the user can not reach the predetermined amount of exercise without moving his or her body, such as turning around, the controller 110 recognizes that the user has not fully woken up (S295) The alarm is continuously maintained (S305).

Thus, only when the exercise amount corresponding to the exercise amount set by the user is satisfied, the user's normal wakeup state is determined by the appropriate body movement, and the alarm of the bio-signal measuring device 100 is released.

In addition, as shown in FIG. 3, other convenience functions include a route service such as a public transportation guide service of a subway or a bus, a taxi call service, and a map search.

As described above, the present invention synchronizes the bio-signal measuring device with the portable terminal of the user to judge whether or not the user's situation is in an emergency state according to the comparison of the measured value of the user's bio-signal and the previously stored health reference value range, The emergency contact information is popped up on the screen of the bio-signal measuring device, and the emergency relief request signal is transmitted to the contact selected by the user's touch.

In this way, the measured bio-signal is compared with the range of the health standard value set by the user to directly determine the emergency situation of the user in detail, and the health standard value range can be determined not by the uniform adult bio- The user can receive the personalized emergency relief service by setting the reference value of the living body signal in consideration of the user.

Further, according to the present invention, when a target sleep time and an alarm time are inputted, a predetermined momentum necessary for an alarm cancellation is set, and when a predetermined target sleep time or an alarm time is reached after the start of sleep, And the alarm is stopped only when the exercise amount exceeds a predetermined exercise amount.

Accordingly, when the user wakes up and the predetermined amount of exercise is measured through the body movement, the user recognizes that the user has woken up to the normal state and stops the alarm, thereby overcoming the limitation of the alarming method of the conventional morning calling function can do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes, modifications, substitutions, and equivalents may be made therein without departing from the spirit and scope of the invention.
