The anti-shock terminal block 131 may include a terminal body 131a, a connection body 131b, and an absorber 131d.

The terminal body part 131a is arranged so as to correspond to the first and second closed curves 131a1 and 131a2 131a1 and 131a2 which are rectangular and open on one side of the upper face, . The terminal body 131a may be formed of a material that can prevent the commercial power from being transmitted to the outside. That is, the terminal body portion 131a may be formed such that at least one of the first and second closed curves 131a1 and 131a2 is arranged to correspond to each other, and one side of the terminal body portion 131a is open in the opposite direction.

In other words, the terminal body portion 131a is formed with at least one partition having a front surface and a rear surface opened, both side surfaces closed, and a plurality of partitions arranged in parallel to each other while maintaining a predetermined gap from both side surfaces, A longitudinal partition may be formed between the side surfaces and formed across the partition.

The connection body portion 131b is formed to cross the first closed loop 131a1 and the second closed loop 131a2 so that the commercial power source flows. The connecting body 131b may be formed in a bar shape having a predetermined width and thickness. Here, the connection body 131b may be formed to penetrate the other surface of the first closed curved surface 131a1 and the other surface of the second closed curved surface 131a2.

The immersion detection control unit 133 controls the electric wave prevention main unit 150 to receive the immersion signal from the electric shock prevention terminal block 131 while the electric shock prevention terminal block 131 absorbs and cancels the electromagnetic of the potential difference. The immersion sensing control unit 133 receives a immersion signal containing immersion information from the electrostatic-discharge-prevention terminal block 131 when the electric-wave plate main unit 150 installed in the exterior floods or generates electric shock due to water, ).

The operation of the disaster warning electric signboard using the electric shock prevention terminal block according to one embodiment of the present invention as described above is as follows.

First, the immersion monitoring control state value can be set (S111). That is, the flooding detection control unit 133 can set the monitoring control state value for the commercial power supply when the electric power board main unit 150 is flooded.

Thereafter, when the flood control surveillance control state value is set, the flooded control perception value can be checked in real time (S112). When the immersion control recognition value appears normally, the electric sign board main unit 150 can guide normal display through the display unit 153 (S113).

If the flood control information is abnormally displayed, the electric sign board main unit 150 can display the emergency flood information guidance through the display unit 153 (S114).

Thereafter, if the emergency flood information guidance guidance is displayed, the control of flooding time can be confirmed (S116). That is, the immersion sensing control unit analyzes whether the electrostatic discharge blocking unit 130 absorbs the electromagnetic potential difference with respect to the commercial power supply for a certain period of time when the electric light plate main unit 150 is submerged, The immersion time control can be confirmed.

For example, if it is possible to absorb and offset the electromagnetic potential difference for commercial power only for 25 hours after flooding, the immersion time control can be set within 24 hours and measures can be taken to be repaired within 24 hours. In other words, once inundation occurs, it can be repaired during the immersion time control by notifying the management system or the manager of the immersion signal containing information about immersion, using wired or wireless.

Accordingly, during the immersion time control, the electric sign board main unit 150 can guide normal display through the display unit 153 (S117).

In addition, if the immersion time set after immersion is exceeded, the power can be shut off (S118). That is, the flooding detection control unit 133 provides a flooding signal containing information to cut off commercial power to the image control unit 155, and when a flooding signal to cut off the commercial power is provided to the image control unit 155, So that all the power sources are turned off.

By operating in this manner, even if the electric sign board main part 150 is flooded in rain or water, the commercial power can be absorbed by the anti-electrostatic terminal 131 and can be canceled, so that an electric shock accident can be prevented in advance.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
