Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a traveling type, particularly an overhead traveling type voice-controlled crane, which can be operated directly by a worker's voice command.

(Prior technology) Conventionally used methods of operating overhead cranes include having a dedicated operator operate a controller in the onboard operator's cabin, or operating a pendant switch suspended near the floor. There are three main types: those operated by the driver on the floor using a radio control device.

(Problems to be Solved by the Invention) Since all of these devices must be operated using one or both hands, a dedicated operator is required to operate the crane. In addition, the work on the entire overhead running lane required a worker to perform auxiliary work such as slinging, setting several ropes, and driving the vehicle, which posed problems in terms of labor saving and work efficiency.

Therefore, the present invention improves the above-mentioned disadvantages of conventional overhead lane operation, eliminates the need for a full-time operator who only operates the crane, and allows one operator to perform multiple tasks for the entire overhead lane. The purpose of the present invention is to provide a mobile voice-controlled crane that is safe, easy to operate, and labor-saving.

(Structure of the Invention) The overhead traveling type voice-controlled crane according to the present invention inputs commands for the operation of each part of the overhead traveling lane by the commander's physical voice from the command input unit, and transmits the input command words to the voice control unit provided with the input command input unit. The voice recognition section compares and recognizes the matching pattern of the commanding person registered in advance, and the control output corresponding to the recognized command word is sent to the ceiling from the output interface section via the control section specific to the voice control crane. A feature of this system is that it is configured to voice-control the overhead traveling lane by outputting to the crane control unit corresponding to the multiple drive devices of the lane.

(Example) The following will explain an example shown in one figure. Fig. 1 shows an example of an overhead traveling voice-controlled crane, and Fig. 2 shows its block diagram. This voice-controlled crane is equipped with a mobile radio device 1 equipped with a headphone microphone 11 carried by the commander. Crane drive connected via voice control panel 2 and crane control panel 3 4.5.6.7
．． Consists of 8.

Here, the voice control panel 2 is provided with a fixed radio device 13 that is installed on the running rod of the crane and has an on-board antenna 12, and receives a signal from the mobile radio device 1 to transmit a voice recognition device 14 to the next stage. Outputs audio signals to.

This voice recognition device 14 is connected to a storage device 115 in which a command word matching pattern for each commanding person is registered in advance. Furthermore, when registering a command word from a commanding person, a verification pattern from the mobile radio device 1 with the headphone microphone 11 can be written.

A control section specific to the voice control crane, that is, a microcomputer 17 and a speech synthesizer 16 are connected to the output side of the voice recognition device 14, and a recognition result signal is output to the microcomputer 17.

Further, the recognition result signal is also output to the speech synthesizer 16 side in the same manner as described above, and the speech synthesizer 16 synthesizes and outputs the same speech as the recognized speech in response to the input recognition result signal. This synthesized voice is wirelessly transmitted from the fixed radio device 13 to the mobile radio device 1 and answered back to the commander via the headphone microphone 11.

An output interface relay 18 is connected to the output of the microcomputer 17.
outputs a sequence activation signal corresponding to the recognition result signal to the output interface relay 18. That is, the microcomputer 17 has built-in predetermined sequences for inching operation, simultaneous operation of two or more operations, combined operation, prevention of erroneous operations, and safety measures that are essential for controlling the crane by voice. A predetermined output is output to the output interface relay 18 in accordance with the recognition result.

The output interface relay 18 outputs a sequence signal to the crane control panel 3, and the crane control panel 3 transmits the drive signal to each drive part 4.5.6.7.8 of the crane, and the crane operates according to the voice command. .

Since the crane control panel 3 and each drive section 4,5,6,7.8 are of a conventional type, their explanation will be omitted.

In the above configuration, the voice signal of the operation direction command for the crane specific unit from the mobile radio device 1 carried by the ground commander is received by the fixed radio device 13 of the voice control panel 2, and is input to the voice recognition device 14. Ru. Therefore, the speech recognition device 14 reads out the matching pattern in the storage device 15, compares it with the input speech signal, and outputs a corresponding synthesized speech output signal to the speech synthesizer 16.

The speech synthesizer 16 creates a synthesized word corresponding to the synthesized sound output signal, and wirelessly transmits it from the fixed radio device 13 to the mobile radio device 1.
The command old number S is answered back via the headphone microphone 11. Then, if the direction command word that the dispatcher commanded himself and the direction command word synthesized and output from the headphone microphone 11 match, when he inputs a driving command word such as "start" from the headphone microphone, the command will be changed as before. It is processed and input to the microcomputer 17 through the same route.

Here, the microcomputer 17 selects the sequence signal corresponding to the direction command word, and outputs the signal from the output interface 1.
8 to the corresponding crane control device to control each part of the crane.

In this way, with a single voice control crane, the crane operates only when the voice recognition device correctly recognizes both the operation direction command word and the operation command word for a specific drive part, so the possibility of malfunction occurring is extremely low.

In addition, when performing inching operation, after inputting the direction command word, by inputting the inching operation command word such as "choi", the inching operation is performed for the time and number of times preprogrammed in the microcomputer 17. can be done.

The above describes the case of only one operation regarding a specific drive part, but simultaneous activation of two or more operations, one individual, arbitrary stop,
Also, arbitrary activation of other operations (two or more operations) during one operation,
Since the microcomputer 17 is programmed to allow stop and inching operations during two operations, operations equivalent to manual operations are possible.

It should be noted that the microcomputer 17 is programmed to perform operations that require a relatively quick response in safety equipment such as the illumination lights 9 and the alarm 10 using only direction commands (without driving commands).

Furthermore, as a safety measure, the mobile radio 1 is equipped with a power switch to cut off the carrier wave, a tilt switch to protect the dead man, and an emergency stop switch. It is configured to prevent malfunctions and accidents by having programs such as stopping when an input is entered and stopping when an input is made outside the predetermined input order.

In this way, since the voice-controlled crane can be directly operated by the voice command of the dispatcher, both hands (or one hand) of the operator are freed from operating the crane. Utilizing this characteristic, we can make workers multi-skilled by performing multiple tasks such as crane operation, slinging, and auxiliary work (setting several cranes, driving a vehicle, etc.). This eliminates the need for labor saving.

In addition, since it is operated using the most natural voice for a single person, anyone can use it without special training, and the wireless device carried by each worker is small, reducing worker fatigue and increasing productivity. can be improved.

In this embodiment, the voice control panel 2 is installed on the aircraft side, but it is also possible to install it on the ground side and control the crane by transmitting the command output via a conventional radio control device. be.

In addition, instead of answering back using a voice synthesizer, it is also possible to use a command confirmation system using indicator lights and various indicators (LED, LCD, plasma, CRT, etc.).

Furthermore, in the case of automatic cranes where the crane is controlled by a host computer, online input/output to the host computer can be performed using the voice control panel's communication function with the computer. The effectiveness of automated crane operation can be improved.

In this embodiment, an explanation was given of a lane that runs overhead, but it can also be applied to various types of cranes installed indoors or outdoors, or to loading machines for continuous conveyance of bulk materials such as stackers, reclaimers, and loaders. .

(Effects of the Invention) The embodiments of the traveling voice-controlled crane according to the present invention are as described above, and the following effects can be achieved.

To provide a traveling voice-controlled crane that does not require a full-time operator who only operates the crane, allows one operator to safely and easily perform multiple tasks on the entire overhead traveling lane by voice control, and is capable of saving labor. I can do it.
