Description of the Related Art In recent years, as a construction method of a high-rise building, a temporary roof has been supported by a temporary support column erected around a building to be constructed, and a building has been constructed with a construction floor under the temporary roof. However, all-weather construction methods that allow construction to proceed even in rainy weather have been adopted. In such an all-weather construction method, the temporary roof is lifted up while successively adding temporary supports as the construction of the building progresses, and an overhead crane is installed on the lower surface of the temporary roof, and The material lifted to the construction floor is transported to the construction site on the construction floor by the overhead crane.

[0003] Such overhead cranes are often used in factories and the like in addition to being used in the above-mentioned construction sites. In such an overhead crane, a dedicated operator generally carries a wired or wireless operating device, and operates the operating device to carry a suspended load.

[0004]

However, in such a conventional overhead crane, the suspended load to be transported is a heavy material such as a material, and therefore, when the suspended load is to be grounded or seated at a predetermined place. However, it is difficult and extremely dangerous for an operator to assist a suspended load while operating the operating device. For this reason, the operator must operate the overhead crane exclusively, and at least one other worker is required to assist the suspended load. Therefore, since the operator who operates the overhead crane and the worker who assists the suspended load are separate, the operator operates the crane while communicating between the two, and the suspended load is seated at the destination. There is a problem that it takes a long time to carry the sheet.

[0005] In view of the above-mentioned problems, the present invention allows a crane to be operated by a voice of an operator, thereby enabling the operator to also serve as a suspended load.
It is an object of the present invention to provide a crane operation system by voice operation and an operation method thereof that can save labor.

[0006]

In order to achieve the above object, according to the present invention, there is provided a crane operating system by voice operation, which is a portable transmission for transmitting an operator's voice command input through a bone-conducting microphone. Receiving the voice command of the operator transmitted from the transmitter and the transmitter and converting the voice command into voice quality, voice analysis and voice recognition, and synthesizing the recognized command by voice and feeding back the voice command to the operator.

Configure by providing a chromatography emission control device, a driving condition indicator for indicating the operation contents of a crane, the.

According to a second aspect of the present invention, there is provided a crane operating method using voice operation, wherein a voice command of an operator input through a bone-conducting microphone is transmitted from a portable transmitter to a voice processing device. The apparatus converts the voice command into a voice, analyzes the voice, and recognizes the voice. At the same time, the recognized command is voice-synthesized, transmitted to a receiver carried by the operator, and fed back. After receiving the operator's acknowledgment voice transmitted by the transmitter when the content matches, the crane control device outputs an operation command according to the voice command to drive the crane, and the current output of the crane Display the operation details on the operation status display.

With the above configuration, the crane operating system and the operating method by voice operation according to the present invention are provided. When an operator transmits a command by voice from a portable transmitter, the voice processing device receives the command and outputs the voice command. Is converted into a voice quality, voice analyzed, and voice recognized. The voice processing device synthesizes the recognized command by voice and feeds it back to the operator, so that the operator can confirm whether the operation command output to the crane is correct. When the content of the feedback matches the content of the voice command transmitted first, the operator transmits an acknowledgment voice by the transmitter and receives the voice by the voice processing device, thereby transmitting the voice to the crane control device. The crane is driven by outputting an operation command according to the voice command.

Therefore, the operator can drive the crane by transmitting a command by voice, and by mounting the portable transmitter and receiver on the body, the operator can freely use both hands. Will be able to use it. For this reason, when a suspended load is to be seated, the operator can assist the suspended load with both hands that are free, and the operator can also serve as one worker dedicated to the assistance.

It is possible to transmit the information, and to suppress the malfunction of the voice processing device as much as possible, thereby enabling safe crane operation. Furthermore, by adding a voice quality conversion function to the voice processing device, the recognition rate of voice commands can be increased even when the operator is not only a male but also a female, so that the operator can be classified among a more unspecified number of persons. You can choose from. Furthermore, when driving the crane, the operation status indicator displays the current operation content of the crane, so that it can be notified to surrounding workers and the surrounding workers can be suspended by the crane. The route on which the load is transported can be confirmed, and the safety in the transport route can be ensured.
