(7) Description of the control process of the driving unit 50

Hereinafter, a control process of the driving unit 50 will be described with reference to FIG. 21 .

The safety jacket 2 according to this embodiment includes a driving unit 50 , a sensor unit 60 , and a control unit 70 , and the control unit 70 uses the information detected by the sensor unit 60 to cause the wearer to fall. It is determined whether or not, and the driving unit 50 is operated based on the determined information.

The sensor unit 60 includes an acceleration sensor module 61 and a gyro sensor module 62 .

The acceleration sensor module 61 senses the wearer's acceleration in a direction away from or close to the ground. In an embodiment, the acceleration sensor module 220 may be an ICP (Integrated Circuit Piezoelectric) type sensor, a capacitance type sensor, a strain gauge type sensor, or the like.

Accordingly, when the wearer falls, the wearer's acceleration may be measured by the acceleration sensor module 61 .

When the acceleration sensor module 61 is installed in the first and second upper arms 31 and 32 or the first and second lower arms 21 and 22, acceleration may be measured by movement of the wearer's arm. . Therefore, even when the wearer does not fall, it may be misjudged as falling.

In consideration of this point, the acceleration sensor module 61 may be installed in the first or second body portions 11 and 12 . In an embodiment, the acceleration sensor module 61 may be installed adjacent to the wearer's neck.

The acceleration sensor module 61 is electrically connected to the control unit 70 , and the wearer's acceleration sensed by the acceleration sensor module 61 is transmitted to the control unit 70 .

The gyro sensor module 62 measures a change in angular velocity that may occur when the body rotates as the wearer falls. In an embodiment, the gyro sensor module 62 may be provided as a gyro sensor or the like.

Accordingly, when the wearer falls, the angular velocity of the wearer may be measured by the gyro sensor module 62 .

When the gyro sensor module 62 is installed in the first and second upper arms 31 and 32 or the first and second lower arms 21 and 22, the angular velocity may be measured by movement of the wearer's arm. . Therefore, even when the wearer does not fall, it may be misjudged as falling.

In consideration of this point, the gyro sensor module 62 may be installed in the first or second body parts 11 and 12 . In an embodiment, the gyro sensor module 62 may be installed adjacent to the wearer's waist.

The gyro sensor module 62 is electrically connected to the control unit 70 , and the angular velocity of the wearer detected by the gyro sensor module 62 is transmitted to the control unit 70 .

The control unit 70 includes a detection information receiving module 71 and a fall information calculation module 72 .

The sensing information receiving module 71 includes an acceleration information receiving unit 711 that is electrically connected to the acceleration sensor module 61 and receives the acceleration sensed by the acceleration sensor module 61 .

In addition, the sensing information receiving module 71 includes an angular velocity information receiving unit 712 that is electrically connected to the gyro sensor module 62 and receives the angular velocity sensed by the gyro sensor module 62 .

The sensing information receiving module 71 transmits the received acceleration and angular velocity to the fall information calculation module 72 .

The fall information calculation module 72 calculates fall information that is information about whether the wearer falls by using the received acceleration and angular velocity.

Fall information can be calculated in the following way.

When the acceleration is greater than or equal to the preset fall acceleration or the angular velocity is greater than or equal to the preset angular velocity of the fall, the fall information calculation module 72 calculates the fall information as falling by the wearer.

If the acceleration is less than the preset fall acceleration and the angular velocity is less than the preset fall angular velocity, the fall information calculation module 72 calculates the fall information as that the wearer does not fall.

Since it is determined whether the wearer falls by using both the acceleration and the angular velocity, it is possible to significantly reduce the possibility of misjudging whether the wearer falls.

The driving unit 50 is energably connected to the control unit 70, and includes first and second upper arm traction motors 51 and 52, first and second forearm traction motors 53 and 54, and first and second body traction motors (55, 56).

When the fall information calculation module 72 calculates the fall information as a fall of the wearer, the control unit 70 controls the first and second upper arm traction motors 51 and 52, and the first and second forearm traction motors 53 , 54) and the first and second body traction motors (55, 56) are controlled to pull the connected wire. In one embodiment, first and second upper arm traction motors 51 , 52 , first and second forearm traction motors 53 , 54 , and first and second body traction motors 55 , 56 are servo motors. etc. can be implemented.

As a result, air is injected into the first and second body expandable parts 111 and 121, the first and second upper arm expandable parts 311 and 321, and the first and second forearm expandable parts 211 and 221. It can be inflated, and it can be suppressed from applying an excessive impact to the operator when it collides with the ground.

Since the wearer does not perform an additional operation and automatically determines whether he has fallen by the sensor, the wearer's work efficiency can be improved. Although described above with reference to the preferred embodiment of the present invention, those of ordinary skill in the art can variously modify and change the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below.
