In the description of the present invention, the term " facility " means various equipment including grounding such as a communication base station, a repeater, a power facility, a broadcasting facility, a railway facility, a ship equipment, .

Electromagnetic waves emitted from the facility may adversely affect surrounding facilities or human bodies. Conversely, electromagnetic waves entering the facility may cause problems with the operation performance of the facility itself. If there is a malicious electromagnetic attack, the facility itself may malfunction or be disabled It causes problems. In order to prevent damage or malfunction of the facility, it is common that the ground is provided and the ground resistance is 0 Ω at the ground electrode. However, there is a certain ground resistance in the process of connecting to the ground. In the case of a problem or leakage of the leakage line in the ground, such a change in the ground resistance value appears, which has been confirmed to affect the electromagnetic wave intensity around the facility.

Therefore, the basic concept of the present invention is to construct a module as a module and process the information by considering that there is a correlation between an abnormality such as a short-circuit of ground and the intensity of an electromagnetic wave, So that it can be inspected.

The abnormality of the grounding may mean that the grounding part is damaged or cut. A detailed description related to the configuration of the ground sensor unit 400 will be described later.

The electromagnetic wave sensor unit 300 is connected to the antenna unit 310 and functions to measure the intensity of electromagnetic waves in a space around the facility. The antenna unit 310 may be, for example, a triaxial isotropic antenna, and may be formed as an electric field probe in which each dipole is orthogonally disposed at intervals of 120 degrees in a spatial direction. However, the configuration of the antenna unit 310 is not limited thereto.

It is preferable that the electromagnetic wave sensor unit 300 and the antenna unit 310 are separated by a distance of at least 1 m so as to avoid mutual interference. The position of the antenna unit 310 is a height of about 1.5 m from the ground, It is possible to calculate the spatial average value of the intensity.

The probes constituting the antenna unit 310 may be arranged singly or in plurality according to the measurement environment. The number of probes arranged is optional depending on the environment in which measurement is required.

The electromagnetic wave sensor unit 300 of the present invention preferably has broadband characteristics so as to measure electromagnetic waves in various environments, and more preferably has a coverage of 1 MHz to 40 GHz.

For this, the electromagnetic wave sensor unit 300 may be configured such that inductors are arranged in parallel as shown in FIG. 6 so that frequency can be changed corresponding to each bandwidth, and an average measurement value of the set measurement period is detected, 120 to enable the user to check the results through the alarm unit 110.

The analyzer 320 is extended from the output terminal of the electromagnetic wave sensor unit 300, The components of the signal line can be additionally displayed. The spectral information of the input and output ends of the electromagnetic sensor unit 300 can be selectively or additionally checked. The signal lines of the input and output ends of each electromagnetic sensor unit 300 may be switched by the switch 330 and connected to the port of the analyzer 320.

At this time, when the resistance value is calculated through the change of the current as described above, the function of receiving the signal of the current value from the ground sensor unit 400 and calculating the resistance value through the signal.

The grounding resistance detection unit 122 and the electromagnetic wave sensor unit 300 can be operated in conjunction with each other and can determine whether the increase of the electromagnetic wave intensity is caused by a problem of the facility itself or by an external attack. For this purpose, the controller 120 may include an algorithm for determining ground resistance and a form of a module of the electromagnetic wave detecting unit, when the ground resistance value and the electromagnetic wave intensity increase together, to determine that the ground resistance and the electromagnetic wave intensity are related to an abnormality of the facility. At this time, it is possible to provide an alarm to the user over the facility due to a change in grounding resistance and an increase in electromagnetic wave strength.
