In one embodiment, the processor 904 in accordance with the present invention determines whether each socket 902a is equipped with a first or a second sensor housing 250, 260, and the first or second sensor housing 250 and 260 can be supplied to the first and second sensor storage boxes 250 and 260 through the respective sockets 902a only when they are mounted on the corresponding sockets 902a.

The reason why the first and second sensor storage boxes 250 and 260 are supplied with power through the respective sockets 902a only when the first and second sensor storage boxes 250 and 260 are installed in the slots in the present invention When the worker continues to supply power to the socket 902a in which the first and second sensor storage boxes 250 and 260 are not inserted when the worker is working in a place where there is much moisture or dust, And there is a risk of sparks due to sparks.

9B, the socket 902a according to the present invention includes first and second terminals 1030a and 1030b for power supply and a third terminal 1030c for signal transmission, The sensor 904 according to the present invention includes a switch 1010 and a gate signal generator 1020. The switch 1010 and the gate signal generator 1020 are connected to each other.

The first terminal 1030a of the socket 902a is a terminal to which a power source voltage Vcc is applied and the second terminal 1030b is a terminal to which a ground voltage is applied, and the third terminal 1030cd is a terminal to which the socket 902a is connected. And the sensing data generated by the first or second sensor storage box 250 or 260 inserted in the second sensor storage box 250 or 260 is transmitted.

The detection terminal 1030d included in the socket 902a is used to detect whether the first or second sensor storage box 250 or 260 is inserted or not. One end of the detection terminal 1030d is connected to a power source The other end of the detection terminal 1030d is electrically connected to the link 1040 to which the voltage Vcc is applied and the other end of the detection terminal 1030d is electrically connected to the first or second sensor accommodating chambers 250 and 260 when the first or second sensor accommodating chambers 250 and 260 are inserted into the socket 902b. And the second terminal 1030b to which a ground voltage is applied through the first and second sensor housings 250 and 260.

Accordingly, if the first or second sensor storage box 250 or 260 is 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. [ A high level detection voltage is applied to the gate signal generator 1020 through the link 1040. [ At this time, 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 receptacles 250 and 260 are connected to the socket 902a, So that the detection voltage applied to the link 1040 becomes a predetermined high level value.

When the first or second sensor storage box 250 or 260 is 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, ) Flows to the ground terminal through the second terminal 1030b, so that a low-level detection voltage is applied to the gate signal generator 1020.

The gating signal generator 1020 generates a gating signal for supplying power to the first or second sensor storage box 250 or 260 inserted in the socket 902a when a high level signal is applied from the detection terminal 1030d, . 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 applied to the gating signal generated during the predetermined initial period (?) After the high level signal is applied from the detection terminal 1030d, (T) is maintained at the high level after the elapse of the initial period (DELTA t). At this time, the gating signal generator 1020 according to the present invention generates a pulse-type gating signal in which the high level and the low level alternate during the initial period (? T) because a sudden power supply causes a spark .
