[0016] Figure 1 This is a schematic diagram illustrating the control device for the working state of a beam-moving machine according to an exemplary embodiment of the present invention.

[0017] Figure 2 This is a circuit diagram of an audio acquisition module according to an exemplary embodiment of the present invention. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0019] In related technologies, operators in the beam-moving machine's control room report during operations, or relevant management personnel observe whether the operators in the control room are fatigued.

[0020] However, the inventors discovered that when observing whether the operator is fatigued using methods in related technologies, it is highly subjective and cannot control the beam-moving machine in a timely manner when the operator is fatigued, which may lead to safety accidents.

[0021] In view of this, the present invention provides a control device for the working state of a beam-moving machine to solve the technical problems existing in the above-mentioned related technologies.

[0022] like Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the control device for the working state of a beam-moving machine according to an exemplary embodiment of the present invention, with reference to... Figure 1 It includes a control module, an image acquisition module, and an image processing module; The image acquisition module is installed in the operator's room of the beam-moving machine. The output of the image acquisition module is connected to the input of the image processing module, the output of the image processing module is connected to the input of the control module, and the output of the control module is used to communicate with the beam-moving machine. The image acquisition module is used to acquire images of the operators of the beam-moving machine and input these images into the image processing module. The image processing module is used to receive images of personnel operations and output images of personnel features, and input the images of personnel features into the control module; The control module is used to control the beam-moving machine to stop working when the personnel feature image matches the target feature image, wherein the target feature image is an image of the operator in a fatigued working state.

[0023] By installing the image acquisition module in the operator's cab of the beam-moving machine, the above technical solution can capture images of the operators in real time. When the personnel feature image matches the target feature image, the beam-moving machine can be controlled to stop working. This allows for timely control of the beam-moving machine even when the operator is fatigued, thereby reducing safety hazards during beam-moving machine operation.

[0024] To enable those skilled in the art to better understand the control device for the working state of the beam-moving machine provided by this utility model, the above modules are described in detail below.

[0025] For example, an image acquisition module can be used to acquire image or video information of the operator. In this embodiment of the invention, the image acquisition module can be positioned in the top area of ​​the beam-moving machine's operating room or in front of the operator, capable of acquiring image or video information of the entire operator, or capable of acquiring image or video information of the operator's face. This embodiment of the invention does not specifically limit the specific location of the image acquisition module. The image acquisition module can be a CCD image sensor, a CMOS image sensor, or a camera, etc.

[0026] The personnel operation image can be image or video information of the operator during the operation of the beam-moving machine. The personnel operation image can be acquired through an image acquisition module. This image can be a black and white image or a color image; this embodiment of the invention does not specifically limit this. The personnel operation image can be a single image, a video image, or multiple consecutive images. After acquisition, the personnel operation image can be transmitted to an image processing module for processing.

[0027] An image processing module is used to extract feature information from an image. In this embodiment of the invention, the image processing module can be a microcontroller equipped with an image feature extraction program, and the output of the microcontroller is connected to the input of the control module, while the input of the microcontroller is connected to the output of the image acquisition module. Image feature extraction can be a method of image feature extraction program in related technologies, thereby enabling the extraction of feature images from images of personnel operation. For example, the image feature extraction program can extract eye feature images from images of personnel operation. These eye feature images can be the degree of eye opening and closing on a face, or they can be feature images of the number of times the operator closes their eyes within a fixed time period, or they can also be feature images of the mouth when yawning in images of personnel operation. The microcontroller can be an STM32+OV7670.

[0028] The control module is a program that determines whether two images are identical in implanted related technologies. The control module can include multiple target feature images, each representing an operator in a fatigued state. When a personnel feature image is input into the control module, it is compared with the target feature images. If the personnel feature image matches the target feature image, it indicates that the operator is fatigued, and the beam-lifting machine can be stopped. If the personnel feature image does not match the target feature image, the beam-lifting machine continues to operate. After the beam-lifting machine stops operating, the operator currently in the control room can be replaced by other personnel, thus ensuring the safety of the beam-lifting machine during operation and reducing the risks associated with its operation.

[0029] By acquiring images of personnel operating the equipment through the image acquisition module, real-time images of the operator's actions during the operation can be captured. When the personnel feature images and target feature images match, the working state of the beam-moving machine can be controlled to stop working, which can improve the safety of beam-moving machine operation.

[0030] In some possible ways, the personnel feature image is an eye feature image or a mouth feature image, and the target feature image includes a target eye feature image and a target mouth feature image of an operator in a state of fatigue.

[0031] It should be understood that, in this embodiment of the invention, the personnel feature image can be an image of the operator's eyes and mouth. The eye feature image can be the degree of eye opening and closing, and the mouth feature image can be the degree of mouth opening. The target feature image can be a target eye feature image and a target mouth feature image of the operator in a fatigued state. The target eye feature image can be an image of the operator's eyes in a fatigued state where the degree of eye opening is less than a preset value, and the target mouth feature image can be a feature image of the maximum degree of mouth opening when the operator yawns in a fatigued state. Therefore, in the image processing module, the eye feature image or mouth feature image of the personnel operation image can be extracted. In the control module, the eye feature image can be matched with the target feature image, or the mouth feature image can be matched with the target feature image. When the eye feature image matches the target eye feature image or the mouth feature image matches the target mouth feature image, the working state of the beam-lifting machine can be controlled to a stopped working state.

[0032] In some possible configurations, the control device further includes an audio acquisition module, the output of which is connected to the input of the control module, and the audio acquisition module is located in the operator's cab of the beam-moving machine. The audio acquisition module is used to collect the voice signals of the beam-moving machine operator and transmit the voice signals to the control module; The control module is used to control the beam-moving machine to stop working when the personnel feature image does not match the target feature image but the sound signal matches the target sound signal. The target sound signal is the sound signal of the operator's working state of fatigue.

[0033] It should be understood that when operators control the beam-moving machine, they may be fatigued if their feature images do not match the target feature images. In this case, the operator may yawn, snore, or express that they are fatigued. Therefore, in this embodiment of the invention, an audio acquisition module is provided to collect the sound signals of the operator operating the beam-moving machine and transmit the sound signals to the control module.

[0034] The control module also includes multiple target sound signals, which can be used to represent the sounds emitted by operators when they are fatigued. If the personnel feature image and the target feature image do not match, the sound signal can be compared with the target sound signal. When the sound signal matches the target sound signal, it indicates that the operator is fatigued and needs rest. Therefore, the working state of the beam-lifting machine can be controlled to a stopped state. The specific method for comparing the sound signal with the target sound signal after determining a mismatch between the personnel feature image and the target feature image is implemented using a judgment procedure method in the prior art, and this embodiment of the present invention does not specifically limit this method.

[0035] In some possible ways, the target sound signal is a snoring signal, a yawning signal, or a voice signal of an operator in a state of fatigue.

[0036] It should be understood that, in this embodiment of the invention, the sound signal can be a signal emitted by the operator during the operation of the beam-moving machine. The target sound signal can be a snoring signal, a yawning signal, or a voice signal indicating that the operator is in a state of fatigue. The voice signal can be a sound signal uttered by the operator indicating drowsiness or fatigue. Therefore, in the control module, the sound signal can be matched with the snoring signal, yawning signal, and voice signal in the target sound signal. When the personnel feature image does not match the target feature image, and the sound signal matches any one of the snoring signal, yawning signal, or voice signal, the beam-moving machine can be controlled to stop working.

[0037] In a possible configuration, the audio acquisition module includes a transistor D2, a sound acquisition module, resistors R2, R3, and R4, capacitor C1, and capacitor C2. The first port of the sound acquisition module is grounded. The second port of the sound acquisition module is connected to the control module through resistor R2 and to the base of transistor D2 through capacitor C1. The emitter of transistor D2 is grounded. The base of transistor D2 is also connected to the collector of transistor D2 through resistor R3. The collector of transistor D2 is connected to the control module through capacitor C2 and resistor R4.

[0038] It should be understood that the specific circuit connection structure in the audio acquisition module can be as follows: Figure 2 As shown, this circuit can be used to collect sound signals from operators while operating the beam-moving machine; however, this embodiment of the invention does not impose specific limitations on this aspect. In this embodiment, the sound acquisition module can be a microphone, a sound card, or a sound sensor; furthermore, this embodiment of the invention does not impose specific limitations on this aspect.

[0039] In a possible configuration, the control device further includes a timing module, a digital-to-analog converter module, and a comparator. The output of the timing module is connected to the input of the digital-to-analog converter module, the output of the digital-to-analog converter module is connected to the input of the comparator, and the output of the comparator is connected to the control module. The timing module is used to collect the operation time signal of the operator on the beam lifting machine and transmit the operation time signal to the digital-to-analog conversion module; The digital-to-analog converter module is used to convert the operation duration signal into a numerical duration signal and transmit the numerical duration signal to the comparator; The comparator is used to send the numerical duration signal to the control module when the numerical duration signal is greater than the preset duration. The control module is also used to control the beam-moving machine to stop working when the personnel feature image and the target feature image do not match within a preset time period and a numerical time period signal is received.

[0040] It should be understood that if, during the operation of the beam-moving machine, the operator's feature image does not match the target feature image within a preset time period, but the operation time exceeds the preset time period, this can also indicate that the operator is fatigued. Therefore, it is necessary to monitor the operator's operation time to prevent the operator from continuing to operate while fatigued, thereby reducing the occurrence of safety accidents during beam-moving machine operation and improving the safety of beam-moving machine operation.

[0041] In this embodiment of the invention, the timing module can be installed in the area where the manager is located. When the operator controls the beam-moving machine, the timing can begin. The timing module can acquire the operation duration signal of the operator on the beam-moving machine, and then the operation duration signal is converted into a numerical duration signal by the digital-to-analog conversion module.

[0042] The preset duration can be the maximum continuous operating time for the operator of the beam-lifting machine. The numerical duration signal is then input to a comparator, which compares it with the preset duration. When the numerical duration signal exceeds the preset duration, and the operator's feature image does not match the target feature image within the preset duration, it indicates that the operator is fatigued, and the numerical duration signal can be directly sent to the control module. Upon receiving this numerical duration signal, the control module can directly control the beam-lifting machine to a stopped state. The process of determining that the operator's feature image does not match the target feature image within the preset duration is based on existing judgment methods, and this embodiment of the invention does not specifically limit this method.

[0043] By monitoring the duration of operation and controlling the beam-moving machine, it is possible to prevent operators from operating the machine while fatigued, thereby reducing the occurrence of beam-moving machine safety accidents and improving the safety of beam-moving machine operation.

[0044] In some possible embodiments, the control device further includes an early warning module, which is installed in the operator's cab of the beam-moving machine, and the input of the early warning module is connected to the output of the control module. The control module is also used to control the early warning module to issue an audible prompt when the personnel feature image matches the target feature image, so as to prompt the operator to stop the operation.

[0045] It should be understood that the control device can also be equipped with an early warning module, which can be installed in the operator's room or in the management area where the manager is located. When the early warning module is installed in the operator's room, when the personnel feature image matches the target feature image, it can indicate that the operator is in a state of fatigue, and the early warning module can then issue an audible prompt to remind the operator to stop operating. When the early warning module is installed in the management area where the manager is located, the audible prompt issued by the early warning module can remind the manager to stop the operator's operation of the beam-lifting machine. The early warning module can be a buzzer, audible speaker, or loudspeaker; this embodiment of the invention does not specifically limit its functionality.

[0046] The above technical solution can determine whether the operator is fatigued based on the image and sound signals of the operator's operation and the operation time signal. If the operator is fatigued, the beam-moving machine can be controlled to stop working. This can realize timely control of the beam-moving machine when the operator is fatigued, thereby reducing safety hazards during beam-moving machine operation.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
