The hard hat 112 is worn on the worker's head to protect the worker from external hazards. Hard hat 112 is made of a material that is strong in impact and light in weight. Hereinafter, a hard hat according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

2 is a perspective view of a hard hat according to an embodiment of the present invention.

As shown in FIG. 2, the hard hat 112 according to the exemplary embodiment of the present invention has the hard hat 112 extending from the wearing part 112a and the wearing part 112a which are parts worn on the operator's head. (112b).

At least one coupling member 112c for coupling the helmet band 114 may be formed on an outer surface of the wearing part 112a. Due to the coupling member (112c) it is possible to increase the adhesion between the helmet 112 and the helmet band 114. In one embodiment, a plurality of coupling members 112c may be formed in the wearing part 112a in order to maximize the adhesion between the hard hat 112 and the hard hat band 114.

An insertion groove 112d may be formed to prevent the helmet band 114 coupled to the wearing part 112a of the extension part 112b from being separated. In one embodiment, the insertion groove 112d may be formed to penetrate the extension 112b, but in another embodiment, the extension 112b may be extended to the extension 112b as shown in FIG. 2A. The protruding member 112e may be formed, and the insertion groove 112d may be formed in the protruding member 112e. In this case, the insertion groove 112d may be formed to penetrate both the protruding member 112e and the extension part 112b.

Meanwhile, a plurality of insertion grooves 112d may be formed in the extension part 112b. For example, the extension part 112b may include two insertion grooves 112d. In this case, the insertion groove 112d may be formed at a position facing each other on the extension portion 112b.

Referring back to FIG. 1, the hard hat band 114 is coupled to the hard hat 112 to be detachably provided to provide various additional functions to the worker. Hereinafter, the helmet band 114 according to the present invention will be described in more detail with reference to FIGS. 3 to 8.

The device connection part 902 may include a plurality of sockets 902a to which the first and second sensor accommodating parts 250 and 260 are detachably mounted, a vibration device connection part 902b to which the vibration device 275 is connected, and a photographing button ( 510, a video conference request button 520, and a plurality of button connection units 902c to which emergency rescue buttons 540 are connected, and a lighting device on / off button connection unit 902d to which the lighting device on / off button 530 is connected. , An ear microphone connector 902e to which the ear 270 is connected, and a camera board connector 902f to which the camera board is connected.

In one embodiment, the processor 904 according to the present invention determines whether the first or second sensor holders 250 and 260 are mounted in each socket 902a, and the first or second sensor holder ( Power may be supplied to the first and second sensor holders 250 and 260 through the sockets 902a only when the sockets 250 and 260 are mounted in the sockets 902a.

In the present invention, the reason why the power can be supplied to the first and second sensor holders 250 and 260 through the sockets 902a is provided only when the first or second sensor holders 250 and 260 are mounted in the slots. When the worker is working in a place with a lot of moisture or dust, when the power is continuously supplied to the socket 902a where the first and second sensor holders 250 and 260 are not inserted, sparks may be generated due to dust or dust. Because there is a risk of fire occurring due to sparks and sparks.

For this purpose, as illustrated in FIG. 9B, the socket 902a according to the present invention may include a first or second terminal in addition to the first and second terminals 1030a and 1030b for power supply and the third terminal 1030c for signal transmission. 2 includes a detection terminal 1030d for detecting whether the two sensor holders 250 and 260 are inserted, and the processor 904 according to the present invention includes a switch 1010 and a gate signal generator 1020.

The first terminal 1030a of the socket 902a is a terminal to which a power voltage Vcc is applied, the second terminal 1030b is a terminal to which a ground voltage is applied, and the third terminal 1030cd is a corresponding socket 902a. A terminal for transmitting the sensing data generated by the first or second sensor holders 250 and 260 inserted into the terminal.

The detection terminal 1030d included in the socket 902a is for detecting whether the first or second sensor holders 250 and 260 are inserted, and one end of the detection terminal 1030d is powered as shown in FIG. 9B. The other end of the detection terminal 1030d is electrically connected to the link 1040 to which the voltage Vcc is applied, and the first or second sensor holders 250 and 260 are inserted into the socket 902b. It is configured to be electrically connected to the second terminal 1030b to which the ground voltage is applied through the two sensor holders 250 and 260.

Accordingly, when the first or second sensor holders 250 and 260 are not inserted into the socket 902a, the power supply voltage applied through the other end of the detection terminal 1030d is applied to the gate signal generator 1020 of the processor 904. As supplied to, the high level detection voltage is applied to the gate signal generator 1020 through the link 1040. In this case, the link 1040 according to the present invention is connected to the source 1050 to which the power supply voltage Vcc is applied through the resistor R, so that the first or second sensor holders 250 and 260 are placed in the socket 902a. When not inserted, the detection voltage applied to the link 1040 is a predetermined high level value.

In addition, when the first or second sensor holders 250 and 260 are inserted into the socket 902b, one end of the detection terminal 1030d is electrically connected to the second terminal 1030b to which the ground voltage is applied. Since the power supply voltage applied to the other end of the () flows to the ground terminal through the second terminal 1030b, a low level detection voltage is applied to the gate signal generator 1020.

This is to prevent sudden power supply to each socket 902a.

When a high level signal is applied from the detection terminal 1030d, the gating signal generator 1020 provides a gating signal for supplying power to the first or second sensor holders 250 and 260 inserted into the socket 902a. Create The gating signal generator 1020 supplies the generated gating signal to the switch 1010.

In one embodiment, the gating signal generated by the gating signal generator 1020 is a predetermined initial period after the high level signal is applied from the detection terminal 1030d, as shown in Figure 9c (Δ [Delta] t is alternated between the high level and the low level, and is maintained at the high level after the passage of the initial period [Delta] t. In this case, the reason why the gating signal generator 1020 according to the present invention generates a gating signal in the form of a pulse in which the high level and the low level are alternated during the initial period (ΔΔt) may be caused by a sudden power supply. To prevent this.
