Hereinafter, with reference to FIG. 5, the process of outputting a warning depending on whether there is an abnormality in the power equipment included in the image captured through the photographing module 200 will be described.

First, the processor 700 can capture an image of a power facility located in front of the user through the photographing module 200 (step S501).

Subsequently, the processor 700 may transmit the image captured through the photographing module 200 to the user terminal 20 through the communication module 300 (step S503). That is, the processor 700 may transmit the image captured through the photographing module 200 to the user terminal 20 through short-range wireless communication.

It is also possible to extract, identify text included in the text area, and transmit the identified text to the smart hard hat 10.

Below, with reference to FIG. 7, we will look at the process of outputting work procedure information and safety rule information of power equipment.

In this case, the user terminal 20 can identify the voice command transmitted from the smart safety helmet 10 and control data transmitted to the smart safety helmet 10 according to the identified voice command.

As another example, assuming that the work procedure information and/or safety rule information is a plurality of pictures, photos, or text, the processor 700 may display information such as previous screen, next screen, zoom in, or zoom out through the input module 100. A voice command may be input from the user, and the input voice command may be transmitted to the user terminal 20 through the communication module 300. In this case, the user terminal 20 can identify the voice command transmitted from the smart safety helmet 10 and control data transmitted to the smart safety helmet 10 according to the identified voice command.

Meanwhile, in the above-described embodiment, the output of work procedure information and/or safety rule information was described as being controlled through the user terminal 20, but the processor 700 itself uses a voice command input through the input module 100. It is also possible to recognize and control the output of work procedure information and/or safety rule information through the output module 400.
