Mode for Carrying Out the Invention
[0019] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below. These examples are merely illustrative, and the present disclosure can be implemented in various modified forms based on the knowledge of those skilled in the art. In this specification and the drawings, components having the same reference numerals indicate the same components as each other.
[0020] (Embodiment 1) The state of the utility pole construction work of the present disclosure is shown in FIG. 2, and the configuration of the utility pole construction system of the present disclosure is shown in FIG. 3. In FIGS. 2 and 3, 10 is a grapple crane, 11 is a first sensor, 12 is a second sensor, 13 is a third sensor, 15 is a control device, and 20 is a utility pole.
[0021] The utility pole construction system of the present disclosure includes a grapple crane 10 that grabs, transports, and works on a utility pole 20, a first sensor 11 that acquires information on terrain and obstacles, and calculates a working path of the grapple crane 10 for performing a desired utility pole construction work based on the terrain and obstacle information acquired in advance, the terrain and obstacle information acquired by the first sensor 11, and information regarding the grapple crane 10 and the utility pole 20, and a control device that controls the operation of the working path of the grapple crane 10.
[0022] The grapple-type heavy machine 10 grabs the utility pole 20 with the grapple and performs transportation and work. The control device 15 has acquired in advance information on the terrain and obstacles. Also, the first sensor 11 uses a camera, millimeter-wave radar, infrared sensor, etc. to detect the terrain and obstacles in real time, and outputs the detected information on the terrain and obstacles to the control device 15. The control device 15 removes noise from the information on the terrain and obstacles acquired by the first sensor 11. This is originally to prevent determining that there are obstacles in a place where there are no obstacles. Also, since information on the terrain and obstacles in a range greatly exceeding the working path of the grapple-type heavy machine 10 is unnecessary, unnecessary information on the terrain and obstacles may be deleted.
[0023] The control device 15 converts the information on the terrain and obstacles into data that can be processed. The control device 15 detects the current position of the grapple-type heavy machine 10 by comparing the information on the terrain and obstacles acquired in advance with the information on the terrain and obstacles acquired by the first sensor 11. The position of the grapple-type heavy machine 10 may be detected using GPS.
[0024] The control device 15 has acquired in advance information regarding the grapple-type heavy machine 10 and the utility pole 20. The control device 15 calculates a working path for the grapple-type heavy machine 10 to perform a desired utility pole construction based on the information on the terrain and obstacles acquired in advance, the information on the terrain and obstacles acquired by the first sensor 11, and the information regarding the grapple-type heavy machine 10 and the utility pole 20 acquired in advance. Information regarding the grapple-type heavy machine 10 includes the position, size, movable radius of the grapple, etc. Information regarding the utility pole 20 includes the dimensions of the utility pole 20, etc. The control device 15 calculates a working path that can move from the current position to the destination for the purpose of performing the desired utility pole construction while avoiding obstacles while maintaining a safe range necessary for the grapple-type heavy machine 10 to grab and transport the utility pole 20. Path running algorithms, inverse kinematics algorithms, etc. can be applied to the calculation of the working path.
[0025] When the grapple crane 10 transports the utility pole 20, if there is a change between the terrain and obstacle information acquired in advance and the terrain and obstacle information acquired by the first sensor 11, the terrain and obstacle information acquired by the first sensor 11 may be used to correct the terrain and obstacle information acquired in advance.
[0026] The control device 15 refers to the information regarding the grapple crane 10 and the utility pole 20, calculates the working path necessary to safely transport the utility pole 20 while avoiding obstacles on the terrain as angle data, and then controls the operation of the grapple crane 10 based on the calculated angle data. While comparing the terrain and obstacle information detected by the first sensor 11 with the calculated working path, the control device 15 controls the operation of the grapple crane 10 so as not to deviate from the calculated working path to the destination. When the grapple crane 10 moves to the destination, the control device 15 stops the grapple crane 10.
[0027] In the utility pole construction system of the present disclosure, it is possible to eliminate the need for skill when the grapple crane 10 transports the utility pole.
[0028] In the previous description, an example where the grapple crane 10 transports the utility pole has been described. However, when the grapple crane 10 is in the case after constructing the utility pole or when heading for the removal of the utility pole, the grapple crane 10 will move without gripping the utility pole. In these cases, information regarding the utility pole is not required for the control device 15.
[0029] (Embodiment 2) The utility pole construction system of the present disclosure will be described with reference to FIGS. 2 and 3. The utility pole construction system of the present disclosure further includes a second sensor 12 that acquires the state of the grapple crane 10, and the control device 15 controls the utility pole construction of the grapple crane based on the state information of the grapple crane 10 acquired by the second sensor 12.
[0030] The second sensor 12 acquires information necessary for the grapple-type heavy equipment 10 to perform work, such as the direction in which the grapple-type heavy equipment 10 is facing, the angle of the grapple, the gripping force, etc. The second sensor may be composed of a plurality of types.
[0031] When the grapple-type heavy equipment 10 moves to a target location where a utility pole is to be constructed, relocated, or removed, the control device 15 causes the grapple-type heavy equipment 10 to use the grapple to perform utility pole construction work, such as constructing, relocating, or removing a utility pole, based on the information acquired by the second sensor. The control device 15 controls the operation of the grapple of the grapple-type heavy equipment 10 while referring to the topography around the target location. An inverse kinematics algorithm can be applied to the operation of the grapple. The control device 15 controls the rotation and bending / stretching of the grapple based on information from an angle sensor, a force sensor, and a torque sensor as second sensors attached to the grapple. After the utility pole construction work is completed, the control device 15 may move the grapple-type heavy equipment 10 to a parking location.
[0032] In the utility pole construction system of the present disclosure, the grapple-type heavy equipment 10 does not require expertise to perform utility pole construction.
[0033] (Embodiment 3) The utility pole construction system of the present disclosure will be described with reference to Figures 2 and 3. The utility pole construction system of the present disclosure further includes a third sensor 13 that detects a moving object, and the control device 15 stops the operation of the grapple heavy equipment 10 based on information on the moving object acquired by the third sensor 13 and information on the grapple heavy equipment 10 and the utility pole 20.
[0034] The moving object may be a person, an animal, a vehicle, etc. The third sensor 13 detects the size, position, speed, etc. of the moving object. The third sensor 13 may be a camera, a millimeter wave radar, an infrared sensor, etc. The first sensor may also be used. The information on the grapple-type heavy machine 10 may include the size of the grapple-type heavy machine 10 and the movable radius of the grapple. The information on the utility pole 20 may include the dimensions of the utility pole 20.
[0035] When the third sensor detects the presence of a moving object within the movable range of the grapple of the grapple crane 10, the control device 15 stops the transportation and working operations of the grapple crane 10. Even when the control device 15 predicts the movement of the moving object and determines that the moving object will move within the movable range of the grapple of the grapple crane 10 within a predetermined time, the control device 15 may also stop the transportation and working operations of the grapple crane 10.
[0036] In the utility pole construction system of the present disclosure, the grapple crane 10 can be safely used for utility pole construction.
[0037] As described above, according to the present disclosure, proficiency in utility pole construction can be made unnecessary.
[0038] The control device of the present disclosure can also be realized by a computer and a program, and it is also possible to record the program on a recording medium or provide it through a network.
Industrial Applicability
[0039] The present disclosure can be applied to the communication industry.
