As shown in FIG. 3, the smart wear 100 according to the present invention includes a smart helmet 200 corresponding to the smart belt 300 and a welding mask, and the smart helmet 200 and the smart belt ( 300 is a wireless communication based on a communication protocol such as Bluetooth 3.0 (RFID), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), or Zigbee (IEEE 802.15.4). Perform communication.

Welding work is used in bridge construction, shipbuilding, steel structures, machine accessories, large pressure equipment, etc.In shipyards, construction sites, machine shops, and various industrial sites dealing with metals, workers use smart helmets as protective equipment. 200 and the smart belt 300 is worn.

Prior to performing the welding operation, the operator first opens the communication path with the central control center 500 by operating the smart helmet 200 (for example, inputting a button). And the work drawing (or design drawing) of the object to be welded to the central control center 500 side is required. In this case, the operator's request message is converted into electrical voice data through a microphone, and the converted voice data is converted into a signal of a wireless transmission type and transmitted to the smart belt 300 through the communication unit 240. Then, the data is output to the wireless network (eg, the access point (AP 400)) again through the communication unit 360 of the smart belt.

Subsequently, when the corresponding work drawing is received from the central control center 500 side as shown in FIG. 6, the controller 220 of the smart helmet 200 displays the received work drawing on the display 270 so that the worker The welding can be done by referring to the work drawing. (S100, S110)

The present invention allows the operator to check whether the defect of the welding state while working. The operator according to the present invention checks the welding accuracy and defects by inspecting the welding site from time to time during the operation.

In order to inspect the welded area, the operator first executes the scan mode (S120). As shown in Fig. 7, the inspection part 260 of the mask body 200A is kept at a predetermined distance from the welded material. Move from the beginning to the end of the welded area. While the scan mode is executed, the first photographing unit 262 scans (photographs) a welded portion in a manner of emitting ultrasonic waves and receiving reflected ultrasonic waves to generate scan information accordingly. In addition, the second photographing unit 264 performs macro shooting of a high resolution (eg, 5 megabytes (Mbyte) or more) of the welding site and generates image information accordingly. The generated information is wirelessly transmitted through the communication unit 240 under the control of the smart helmet controller 220. (S130)

In the present invention, when scanning (photographing) a weld, it is important to constantly move the inspector 260 along the weld and the space between the inspector 260 and the weldment. To this end, the control unit 220 according to the present invention runs the camera in the scan mode, the image of the object (for example, the weldment being photographed) and the predetermined guard line and the object to be photographed (for example, working) And distance information with the phosphorus weldment) is output to the display 270. The operator moves the inspector 260, that is, the mask body 200A, while checking whether the guide line and the object (for example, the weldment in operation) match through the display 270, and also the distance information on the display 270. The mask body 200A is moved while maintaining a distance from the object (eg, a weldment being worked).

Signals transmitted from the smart helmet 200 through the step S130 are transmitted to the smart belt 300 and wirelessly transmitted again through the second communication unit 360 of the smart belt. And it is transmitted to the central control center 500 via the access point (400).

Once the scan information and the image information are received from the smart belt 300, the central control center 500 performs an inspection test based on the received information. The control center 500 first inserts the received scan information into an ultrasonic flaw detection process to detect pores, cracks, inclusions, fatigue cracks, and the like in the welded site. In addition, the received image information is subjected to ordination examination by experts with experience in the field. Through the ultrasonic inspection process and ordination test, it is determined whether the welding operation is passed or failed.

The determination result of the control center 500 is transmitted to the smart helmet 200 via the access point 400 and the smart belt 300, the control unit 220 displays the determination result (pass or fail) to the worker do. (S140) The determination result of the control center 500 may include not only pass / fail status, but also the findings of the expert who performed the ordination test and the detailed test result of the ultrasonic flaw detection process. If the result of the determination fails, the worker dismantles the welding site and repeats the welding operation until the acceptance decision is made. (S170)

The operator divides the entire work into several sections, and repeats the inspection process for each section, so that the welding work can be completed quickly and accurately. (S150, S160)

In addition, the smart helmet 200 detects the internal / external temperature of the mask body 200A through the sensing unit 210, the illumination around the worker, or the worker's surroundings, while the worker performs the welding operation. Sensing the humidity, gas (gas) for the human body, a shock from the outside applied to the helmet, or detects the direction and position of the current working point to generate the sensing signal accordingly. In addition, the camera receives images (videos or still images) around the worker photographed through the camera, or a sound of the worker or the worker's surroundings through a microphone.

The controller 220 of the smart helmet then transfers the generated (or input) information to the central control center 500 through the smart belt 300 and the access point 400.

Once the information on the work site is received from the smart belt 300, the central control center 500 infers (or monitors) the situation of the industrial site and the safety situation around the worker based on the received information, and infers the result. Delivers a control signal or a warning notification signal informing the dangerous situation according to the smart wear.

The central control center 500 can control the work situation of the site in a variety of ways.

An experienced expert of the central control center 500 may control unskilled workers in the field while monitoring real-time information (for example, video recording a scene, various sensing information, etc.) transmitted from the smart wear 100. . Workers on site perform a highly specialized task under the control of the center 500.

The central control center 500 may analyze the information transmitted from the smart wear 100 to detect a risk factor around the worker that the worker does not recognize, and may transmit a warning signal to the worker.

The central control center 500 may share and supervise the work situation through communication with the surrounding workers wearing the smart wear 100. Can respond quickly and smoothly to on-site emergency situations.

The command or control signal (eg, warning signal, etc.) sent by the central control center 500 is transmitted to the second communication unit 360 of the smart belt 300 via the access point 400. In addition, the control unit 320 that detects the command (or control signal) of the central control center 500 transmits to the smart helmet 200 through the first communication unit 340. And, it outputs to the worker through the A / V input and output unit 230.
