At this time, the beam includes wheels to move along the rail. The ceiling crane includes a trolley. The trolley is moved in a second direction along the beam. At this time, the trolley includes wheels to move along the beam. The trolley is moved in a first direction by the beam moving along the rail. That is, the trolley is moved in the first direction and the second direction. Hereinafter, the ceiling crane position recognition apparatus 100 of the present invention will be described. In addition, a description will be given of a case where the first direction is a vertical direction and the second direction is a horizontal direction.

The position detector 110 includes an infrared emitter 111. The infrared emitter 111 emits infrared rays to the landmark 160 installed on the ceiling of a factory or a warehouse. In addition, the infrared emitter 111 emits infrared rays at regular time intervals.

The position detecting unit 110 includes an infrared detecting unit 112. The infrared detector 112 detects infrared rays reflected from the landmark 160.

The position detecting unit 110 includes a position detecting control unit 113. The position detection controller 113 adjusts the time interval of the infrared rays emitted from the infrared emitter 111. The position detection control unit 113 detects the position of the trolley 150 when infrared light is emitted from the infrared light emitting unit 111. The position detection controller 113 detects the position of the trolley 150 when the infrared ray is detected by the infrared ray detection unit 112. The position detection control unit 113 obtains the difference between the position at which the infrared rays are emitted and the position at which the infrared rays are sensed, thereby generating movement data in which the trolley 150 is moved.

The position sensing unit 110 communicates with the output unit 140 wirelessly. The position detection control unit 113 converts the movement data into a packet form. Therefore, the position sensor 110 wirelessly transmits the movement data to the output unit 140.

The plurality of landmarks 160 are installed in the longitudinal direction of the ceiling of the factory or warehouse. In addition, the plurality of landmarks 160 are installed at intervals of 2 to 3 m on the ceiling of the factory or warehouse. In this case, the landmark 160 is displayed in absolute coordinates on the output device 143 of the output unit 140.

When the trolley 150 moves in the vertical and horizontal directions, the position detecting unit 110 is moved in the vertical and horizontal directions. The infrared emitter 111 emits infrared light toward the landmark 160. The infrared detector 112 detects infrared rays reflected by the landmark 160. The position detection control unit 113 measures the position where the trolley 150 is moved based on the reflected infrared rays.

The first rotation sensing unit 120 is wirelessly connected to the output unit 140. The first control unit 122 converts the first separation distance data into a packet form. Therefore, the first rotation detecting unit 120 wirelessly transmits the first separation distance data to the output unit 140.

The first rotation detecting unit 120 includes a first transmitting unit 123. The first transmitter 123 transmits the first separation distance data converted into a packet form through the antenna 124 to the output unit 140.

When the beam is moved in the vertical direction, the trolley 150 is moved in the vertical direction. When the trolley 150 is moved in the vertical direction, the position detecting unit 110 measures the position where the trolley 150 is moved in cm.

When the beam is moved in the vertical direction, the first rotation detecting unit 120 measures the position where the beam is moved in mm units. That is, the ceiling crane position recognizing apparatus 100 may accurately measure the distance that the trolley 150 is moved in the vertical direction by the position detecting unit 110 and the first rotation detecting unit 120.

The second rotation sensing unit 130 is wirelessly connected to the output unit 140. The second control unit 132 converts the second separation distance data into a packet form. Therefore, the second rotation detection unit 130 wirelessly transmits the second separation distance data to the output unit 140.

The second rotation detecting unit 130 includes a second transmitting unit 133. The second transmitter 133 transmits the second separation distance data converted into a packet form through the antenna 134 to the output unit 140.

When the trolley 150 is moved in the horizontal direction, the position detecting unit 110 measures the position where the trolley 150 is moved in cm. When the trolley 150 is moved in the horizontal direction, the second rotation detecting unit 130 measures the position where the trolley 150 is moved in mm units.

That is, the ceiling crane position recognizing apparatus 100 may accurately measure the distance that the trolley 150 is moved in the horizontal direction by the position detecting unit 110 and the second rotation detecting unit 130.

The ceiling crane position recognition apparatus 100 includes an output unit 140. The output unit 140 includes a receiver 141. The receiver 141 receives the movement data, the first separation distance data, and the second separation distance data through the antenna 144.

The output unit 140 includes an output control unit 142. The output controller 142 checks the position where the trolley 150 is moved based on the movement data, the first separation distance data, and the second separation distance data.

The output control unit 142 checks the position where the trolley 150 is moved based on the arbitrary landmark 161. The output control unit 142 separates the position where the trolley 150 is moved into the vertical component (A) and the horizontal component (B).

The output controller 142 checks the vertical component A based on the vertical component of the moving data and the first separation distance data.

The output control unit 142 adds the first separation distance data to the vertical component of the movement data to identify the position where the trolley 150 is moved. At this time, the output control unit 142 resets the first separation distance data whenever the trolley 150 is moved 1 cm in the vertical direction. The first separation distance data is prevented from accumulating and adding to the movement data. Thus, the position where the trolley 150 is moved in the longitudinal direction is measured to mm unit.

The output control unit 142 identifies the horizontal component B based on the horizontal component of the movement data and the second separation distance data.

The output control unit 142 adds the second separation distance data to the horizontal component of the movement data to identify the position where the trolley 150 is moved. At this time, the output control unit 142 resets the second separation distance data whenever the trolley 150 is moved by 1 cm in the horizontal direction. The second separation distance data is prevented from accumulating and adding to the movement data. Therefore, the position where the trolley 150 is moved in the horizontal direction is measured to mm unit.

The ceiling crane position recognition apparatus 100 accurately measures the position where the trolley 150 is moved in the vertical and horizontal directions. Therefore, the user can accurately check the position where the trolley 150 is moved by the ceiling crane position recognition apparatus 100.

In addition, the user can check the position where the trolley is being moved without a hand signal.

Therefore, the ceiling crane position recognizing apparatus 100 can prevent a human accident due to the falling of heavy objects. In addition, the user can move the weight exactly where desired inside the factory or warehouse.

The output unit 140 may include a memory (not shown). The memory is coupled to the output control unit 142. The memory may store the location where the trolley 150 is moved. In addition, the memory may store a location where the trolley 150 will be moved.

At this time, the output device 143 displays the location stored in the memory. Thus, the user can accurately move the weight to the same location inside the factory or warehouse.
