1 is a block diagram showing the structure of an electromagnetic field monitoring and tracking device according to an embodiment of the present invention.

Referring to FIG. 1, the electromagnetic field monitoring and tracking device 100 constantly measures electromagnetic fields radiated from various electromagnetic emission sources, remotely monitors them in real time, and tracks dangerous levels of emission sources. The frequency scanning unit 104, the database unit 106, the monitor unit 108, the tracking unit 110, the remote transmission unit 112, the remote monitor unit 114 may be included.

Specifically, the reception sensor unit 102 receives a wideband electromagnetic field signal, and detects electromagnetic fields radiated from emission sources using various transmission frequencies and includes at least one wideband high sensitivity antenna capable of wideband measurement over a wide frequency band. can do. The received wideband electromagnetic field signal may be transmitted to the frequency scanning unit 104.

The frequency scanning unit 104 performs frequency scanning to view the waveform of each service in the frequency band with respect to the broadband electromagnetic field signal received from the reception sensor unit 102. Each service signal can be scanned for visible spectrum and intensity in the frequency domain. That is, the frequency scanning unit 104 may check the measured value for each service signal.

The database unit 106 may store the human body protection reference value information for the electromagnetic field necessary for comparing the human body protection reference values of the professional and the public for each service signal occupying different frequencies.

Figure 2 is a graph showing the human body protection criteria for the professional and the public for the electromagnetic field according to an embodiment of the present invention, (a) shows the exposure limit and peak value for the public and occupational personnel as the human body protection reference value for the electric field. (b) shows the exposure limit and peak value for the public and occupational human body as the reference value for human body protection against magnetic field.

As described above, since the database unit 106 stores the human body protection reference value based on the frequency, the database unit 106 targets each service signal detected by the reception sensor unit 102 and identified by the frequency scanning unit 104. The comparison can store basic data for calculating the peak exposure index.

The monitor unit 108 compares the reference value of the database unit 106 with the service-specific measured values transmitted from the frequency scanning unit 104 to calculate a peak exposure index, which is a measured value compared to the human protective reference value, and has a maximum value of the service signal and the risk. Information about the electromagnetic field emission source of the level may be transmitted to the tracking unit 110 and the remote transmission unit 112.

Here, the peak exposure index may be calculated through Equation 1 below.

That is, the monitor 108 may calculate the peak exposure index value, which is a comparison value between the electromagnetic field strength and the human body protection standard for each service signal, by using Equation 1 above, and radiates a dangerous electromagnetic field. The information about the circle may be input from the tracking unit 110, and image information about the circle may be transmitted to the remote monitor unit 114 through the remote transmission unit 112.

As described above, the monitor 108 determines whether the peak exposure index exceeds a preset reference value, and the preset reference value is not limited to the human protection reference value, but may be set to various values.

The tracking unit 110 may receive the frequency of the service signal having the highest peak exposure index from the monitor unit 108 and search for the direction and location of the signal source. That is, the tracking unit 110 receives information such as the center frequency of the service having the maximum peak exposure index from the monitor unit 108 and detects the direction and position tracking for identifying the direction of arrival of the signal and the location of the electromagnetic field emission source. It may include a system.

Meanwhile, when the tracking unit 110 receives a tracking control command from the remote monitor unit 114, the tracking unit 110 may perform an operation (for example, searching for the direction and position of the emission source, performing continuous tracking, and the like).

The remote transmitter 112 may remotely transmit information received from the monitor 108 via a wired or wireless communication network, and monitor the value displayed on the monitor 108 in real time at a distance. It can be transmitted to the remote monitor 114 using a variety of wired / wireless communication networks, such as the Internet network, mobile communication network.

In addition, the remote monitor 114 may perform a real-time monitoring of the signal received from the remote transmitter 112 at a long distance, and may feed back information about the dangerous electromagnetic field emission source to the tracking unit 110. That is, the remote monitor 114 may monitor the electromagnetic field environment at various points coming in through the remote transmitter 112 and check image information of an emission source that radiates a dangerous level of electromagnetic field. The tracking control command may be transmitted to the tracking unit 110.

3 is a flowchart illustrating an operation procedure of an electromagnetic field monitoring and tracking device according to an embodiment of the present invention.

Referring to FIG. 3, in step 300, the reception sensor unit 102 in the electromagnetic field monitoring and tracking device 100 receives wideband electromagnetic field signals from signal sources at various positions. In operation 302, the frequency scanning unit 104 extracts a waveform for each frequency band from the broadband electromagnetic field signal received from the reception sensor unit 102 through frequency scanning.

In step 304, the monitor unit 308 refers to the database unit 106 in which the human body protection reference value for the electromagnetic field is stored, calculates the peak exposure index, and determines whether the peak exposure index calculated in step 306 is equal to or greater than the preset reference value. do.

Therefore, if the peak exposure index calculated in step 306 is lower than the reference value, the process proceeds to step 308 to continuously monitor, and if necessary, transmits to the remote monitor unit 114 through the remote transmission unit 112 to remote in step 312. The monitor 114 monitors the electromagnetic field environment at various points in real time.

However, if the peak exposure index calculated in step 306 is higher than the reference value, the flow proceeds to step 310 and in step 310 the remote transmission unit 112 for the emission source for radiating the electromagnetic field of the dangerous level transmitted from the monitor 108 The information is transmitted to the remote monitor 114.

Accordingly, in step 312, the remote monitor 114 transmits a tracking control command for the emission source that radiates an electromagnetic field of a dangerous level to the tracking unit 110. The tracking unit 110 searches for and tracks the position of the corresponding emission source.

As described above, the apparatus and method for real-time monitoring and tracking of the electromagnetic field according to the embodiment of the present invention constantly measures the intensity of the electromagnetic field radiated from the electromagnetic field emission source in various active areas including electromagnetic field-vulnerable areas such as schools, playgrounds, and hospitals.
