In an embodiment of the present invention, a smart watch refers to an electronic device capable of wirelessly connecting to a user terminal, worn on a body such as a user's wrist or wrist, and also serving as a watch. A smart watch can transmit and receive data based on short-distance wireless communication with a user terminal, and when the smart watch communicates with an external object, it can directly communicate with an external object, but can also communicate with an external object via the user terminal.

The smart watch 100 includes a communication module 110 , a memory 120 , a processor 130 and a geomagnetic sensor 140 , and a display unit 150 .

In detail, the communication module 110 may be connected to a user terminal (eg, a smart phone) through a local area network. Furthermore, the communication module 110 may perform a role of receiving a data request from at least one terminal and transmitting data in response thereto.

Here, the communication module 110 may be a device including hardware and software necessary for transmitting and receiving signals such as control signals or data signals through wired/wireless connection with other network devices.

In the memory 120, a program for performing a smart watch-based live wire detection method is recorded. In addition, the processor 130 performs a function of temporarily or permanently storing the processed data. Here, the memory 120 may include magnetic storage media or flash storage media, but the scope of the present invention is not limited thereto.

The processor 130 controls the entire process of providing a smart watch-based live wire detection method as a kind of central processing unit. Each step performed by the processor 130 will be described later with reference to FIG. 3 .

The geo-magnetic sensor 140 measures an azimuth using the earth's magnetic field, and may measure geomagnetism with respect to three axes of the X-axis, Y-axis, and Z-axis in uT (microtesla) units. Here, the earth magnetic field sensor 140 is a sensor that uses the magnetoresistance effect or the Hall effect, and infers the geomagnetism from the relationship between the magnetic field and the resistance through a phenomenon in which the resistance of a semiconductor or metal material changes according to the magnetic field, or is perpendicular to the magnetic field in the semiconductor material. When a current flows in one direction, the voltage in the direction perpendicular to the direction of the magnetic field and the current is called a Hall voltage, and the magnetic field can be inferred inversely by measuring it.

The geomagnetic sensor 140 built into the smart watch 100 can measure electric and magnetic forces to measure the three-dimensional direction, and can measure changes in the surrounding magnetic field using these, and the effect of high-voltage wires By measuring the changing magnetic field, it is possible to check the presence or absence of a high-voltage line.

The display unit 150 is an element constituting the smart watch 100, and is composed of a display module including an LED or LCD. In addition, when a warning alarm signal is not received, the current situation or live wire magnetic force information and live wire proximity information provided from the smart watch 100 may be provided to the user through the display.

In addition to the geomagnetic sensor, various other biometric sensors for measuring the user's biometric data such as heart rate measurement or blood pressure measurement may be included.

Hereinafter, a smart watch-based live wire detection method according to an embodiment of the present invention will be described with reference to FIG. 3 .

An application for live wire detection may be pre-installed in the smart watch. In addition, it is possible to collect the measurement values of the earth magnetic field sensor 140 through the earth magnetic field sensor 140 built in the smart watch 100 . (S510)

Through the geomagnetic sensor 140 built in the smart watch 100, it is possible to collect the measurement value of the geomagnetic sensor 140 at the current location in real time. The geomagnetic sensor 140 may measure an electromagnetic force or a magnetic force in a three-dimensional space.

In this case, the collected earth magnetic field sensor 140 value may be a 3-axis earth magnetic field sensor 140 value including an X-axis earth magnetic field value, a Y-axis earth magnetic field value, and a Z-axis earth magnetic field value.

It is possible to convert the collected geomagnetic sensor 140 value into a magnetic force measurement value. (S520)

The earth magnetic field sensor 140 measured and collected through the earth magnetic field sensor 140 of the smart watch 100 may be substituted into a preset magnetic force measurement conversion equation to be converted into a magnetic force measurement value.

At this time, the magnetic force measurement conversion equation can be expressed as [Equation 1] below.

[Equation 1]

It is possible to convert the measured value of the earth magnetic field sensor 140 collected through A Y-axis earth magnetic field value, Z may be a Z-axis earth magnetic field value.

In this case, the converted magnetic force measurement value may provide live wire magnetic force information of the measurement point as a numerical value to the screen of the smart watch 100 .

In addition, live wire magnetic force information and live wire proximity information of the measurement point may be provided on the screen of the smart watch 100 . The live wire magnetic force information may be information on the degree of magnetic force of the live wire at the measurement point, and the live wire proximity information may be distance information from the measurement point to the live wire.

As a further embodiment, when providing the live magnetic force information of the measurement point through the screen of the smart watch 100, it may be provided through a graph or an image that can intuitively identify a danger signal or a safety signal.

The smart watch 100 may provide an alarm when the converted magnetic force measurement value is greater than or equal to a reference value according to a preset algorithm. (S530)

Here, the preset algorithm sets a reference value based on pre-stored measurement data and compares the magnetic force measurement value with the reference value, and the pre-stored measurement data is data obtained by measuring the magnetic field of a transmission tower of a high-voltage line and a transmission tower of a high-voltage line, 4 is an exemplary view showing a transmission tower of a high-voltage wire and a magnetic field measurement of a high-voltage wire transmission tower.

The data obtained by measuring the magnetic field of high-voltage power transmission towers and high-voltage power transmission towers can be set based on the average value of field measurements on the effect of electromagnetic waves according to the transmission line distance and the year-round average estimated value of the influence of electromagnetic waves according to the transmission line distance. .

The average value of field measurements for the effect of electromagnetic waves according to the distance of the transmission line is shown in [Table 1] below. In Table 1, the horizontal axis means the distance between the smart watch 100 and the live wire, and the vertical axis is the voltage of the current flowing in the live wire. can mean

The annual average estimated value of the effect of electromagnetic waves according to the transmission line distance is shown in [Table 2] below. In Table 2, the horizontal axis means the distance between the smart watch 100 and the live wire, and the vertical axis is the voltage of the current flowing in the live wire. can mean

The reference value may be set differently depending on the distance between the live line and the smart watch 100 and the voltage of electricity flowing through the live line.

For example, when the reference value is set to 300 μT according to the preset algorithm, the numerical values of the portions marked with the diagonal pattern in Tables 1 and 2 above are greater than or equal to the reference value. The smart watch 100 may provide a notification.

The alarm provided by the smart watch 100 may be at least one method including a vibration, a warning sound, or a method of emitting light through a flash of a camera built in the smart watch 100 .

Meanwhile, the smart watch 100 may perform an additional function of collecting health information of the user.

Hereinafter, a method of collecting health information of a user through the smart watch 100 according to an embodiment of the present invention will be described with reference to FIG. 5 .

The user's health information may be collected through a sensor built into the smart watch 100 . (S710)

The user's health information collected by the smart watch 100 may include various other biometric information such as the user's electrocardiogram and blood pressure.

The smart watch 100 may transmit the collected user's health information to the server. (S720)

The smart watch 100 may transmit the collected health information of the user to the server, and the real-time health information of the user may be provided to the user through the screen of the smart watch 100 according to the user's request.

When receiving an abnormal signal of the health information of the smart watch 100 user from the server, the smart watch 100 may operate a warning alarm. (S730)

The smart watch 100 may provide a warning alarm to the user through vibration, a warning sound, or flashing of the screen.

In a further embodiment, the server may manage the user's health information by dividing it into grades.

For example, the server classifies the user's health information into risk, caution, normal, and safe, and when a serious problem occurs to the user's health such as myocardial infarction or electric shock, the server automatically sets the risk level to the rescue team. can be called, or an alarm can be provided to a nearby smart watch or a nearby user terminal, and a treatment method suitable for the current emergency can be provided along with the alarm.

At the caution stage, the user's health information can be used by dividing the user's health status into grades that are higher than usual or higher than the reference value, usually no different from usual, and the user's condition is good for relief. .

As a further embodiment, the smart watch 100 shares information on the area where the live line is sensed with another object (user terminal, other smart watch, or server, etc.) or when another object approaches the area where the live line is detected, A warning alarm can be provided to the terminal of the corresponding object.

As an additional embodiment, the magnetic force measurement value sensed by the smart watch 100 may be divided into magnetic force classes based on a predetermined value, and the alarm that the smart watch 100 operates may be different according to the magnetic force class. For example, when the magnetic force level is high, the smart watch 100 may operate the alarm sound to the maximum including the alarm unit, or may operate the warning alarm differently according to the level in a way that vibrates and sounds the alarm at the same time.

In a further embodiment, the server collects the GPS signal of the smart watch 100 (GPS signal of the smart watch when the GPS module is mounted inside the smart watch) or the GPS signal of the user terminal, and a plurality of signals are collected at a nearby location If not, an alarm may be provided to the terminal or an alarm may be provided to another object (eg, other user terminal, other smart watch, server, etc.) located in an adjacent location. A live line operation is a task in which at least two or more persons perform work, and when at least two persons are not in close proximity when a live line is detected, an alarm is provided to another object so that a plurality of persons can perform the work. can do.

In a further embodiment, the server collects the magnetic force measurement value of the live wire sensed from the smart watch 100, stores the time the user is exposed to the magnetic force and the magnetic force value of the exposure time, and updates the user's health information through this can do.

The server updates the user's health information and updates the user's health information to prevent industrial accidents caused by disease induction by tracking disease-causing factors, including the amount of time exposed to the magnetic field and the magnitude of the exposed magnetic field. It is possible to provide an alarm to the operator or provide the administrator with the status of the user whose health information is at a dangerous level.

For example, if the magnetic force of a live wire is measured in real time, and the change in magnetic force during the worker's work hours and work is stored in real time and transmitted to the server, the reference value for the magnetic force state in daily life can be checked.

Since the reference value for the magnetic force in daily life and the magnetic force value when the operator approaches the live wire for live wire work are changed, the start and end of the worker's work can be identified through the change in the measured magnetic force.

In addition, by storing the change in the magnetic force of the worker in real time, the worker can understand the change in the magnetic force value exposed to the worker during work hours in time series, and it can be transmitted and stored to the server, and the user's health information from the smart watch 100 can be collected through handwriting input or automatic extraction, and the user's health status according to the magnetic force exposure value and magnetic force exposure time can be recorded and stored for each user.

When a user has a disease based on these values, it can be used as a basis for determining the industrial accident impact information by comparing it with the values of other users. For example, according to the big data collected by the server, in the case of other users, after being exposed to a live magnetic force of 200uT four times a week for 6 years, the analysis can be completed as a change in heart rate or a disease such as high blood pressure. At this time, if a user develops leukemia after being exposed to a live magnetic force of 250uT 5 times a week for 6 years, big data collected from other users can be used as evidence. The server may provide data of these other users to a smart watch or a user terminal (smartphone).

As an additional embodiment, the magnetic force value measured by the smart watch 100 may be stored, and the type of work performed by the smart watch 100 may be received and stored. Through this, the average magnetic force value for each task may be collected. After that, if a magnetic force value much higher than the average magnetic force value is received despite performing the same task, there is a risk of exposure to excessive electromagnetic waves, so a notification or warning can be sent to another object to request a work stop.

In the above-described additional embodiment, transmission/reception between the smart watch 100 and the server may be performed directly, but data may also be transmitted/received by a user terminal (ie, a smart phone) interposed between the smart watch 100 and the server.

An embodiment of the present invention may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by a computer. Computer-readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. Also, computer-readable media may include any computer storage media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data.
