[0039] Figure 1This illustration schematically shows a structural diagram of a safety monitoring display screen for construction machinery according to an embodiment of this application. Figure 1 As shown in this application, a safety monitoring display screen 100 for construction machinery is provided. The safety monitoring display screen 100 is installed in the operator's control room of the construction machinery. The safety monitoring display screen 100 may include:

[0040] Image acquisition module 111 is used to acquire image signals of workers related to the workers.

[0041] The audio and video call signal acquisition module 112 is used to acquire the audio and video call signals of the operators.

[0042] The face recognition module 121 communicates with the image acquisition module 111 to receive and recognize the image signal of the operator in order to obtain the face recognition result of the operator.

[0043] The audio and video call module 122 communicates with the audio and video call signal acquisition module 112 to receive and transmit audio and video call signals.

[0044] The operation behavior recognition module 123 communicates with the image acquisition module 111 to receive the image signal of the operator and to recognize the operation behavior of the operator in order to obtain the operation behavior recognition result of the operator.

[0045] The display module 131 communicates with the image acquisition module 111, the face recognition module 121, the audio and video call module 122, and the operation behavior recognition and processing module 123. The display module 131 is used to receive and display the image signal of the operator, the face recognition result, the audio and video call signal, and the operation behavior recognition result.

[0046] It is understood that the construction machinery can be tower cranes or other construction machinery, and the safety monitoring display screen can be installed in the operator's control room of the construction machinery for easy image acquisition. The image acquisition module 111 is hardware used to acquire image signals of the operators. There can be one or more image acquisition modules 111. If there is only one image acquisition module 111, it can be placed in the center of the safety monitoring display screen; if there are multiple modules, they can be distributed across the display screen. The operator image signals can include, but are not limited to, facial image signals and operational behavior image signals of the operators. The audio / video call signal acquisition module 112 is hardware used to acquire audio / video call signals, and can include hardware such as cameras and microphones for acquiring audio / video call signals. There can be one or more audio / video call signal acquisition modules 112. The face recognition module 121 is a module equipped with a face recognition algorithm. It can be used to perform face recognition on the face image signal in the worker's image signal, thereby obtaining the face recognition result. The face recognition module 121 uses conventional face signal recognition methods to recognize the worker's image signal. The face recognition module 121 can be a conventional chip or other functional module with face recognition capabilities, which will not be described in detail here. The audio / video call module 122 is a module used to receive and transmit audio / video call signals. The audio / video call module 122 can be a conventional chip or other functional module capable of implementing audio / video call functions. The operation behavior recognition module 123 is a module equipped with a behavior recognition algorithm. It can be used to recognize the worker's operation behavior on the operation behavior image signal in the worker's image signal, thereby obtaining the worker's behavior recognition result. The operation behavior recognition module 123 uses conventional operation behavior signal recognition methods to recognize the worker's image signal. The operation behavior recognition module 123 can be a conventional chip or other functional module with operation behavior recognition capabilities, which will not be described in detail here. The display module 131 is a module for displaying image signals. The display module 131 can communicate with the image acquisition module 111, the face recognition module 121, the audio and video call module 122 and the operation behavior recognition and processing module 123 respectively. It can also receive and display the image signals of the operator, the face recognition results, the audio and video call signals and the operation behavior recognition results.

[0047] Specifically, after the image acquisition module 111 acquires the image signal of the operator related to the operator, the face recognition module 121 and the operation behavior recognition module 123 communicate with the image acquisition module to receive and recognize the image signal of the operator, and obtain the face recognition result and the operation behavior recognition result respectively. Facial recognition of worker images is used to control the operating permissions of the control room on the construction machinery, ensuring the safety performance of the machinery. Furthermore, the recognition of worker actions can identify potential safety hazards during machinery operation, such as drowsiness, ensuring worker safety while guaranteeing the normal operation of the machinery. An audio / video call signal acquisition module 122 collects and transmits worker audio / video call signals. A display module 131 communicates with the image acquisition module 111, facial recognition module 121, audio / video call module 122, and action recognition processing module 123, receiving and displaying worker image signals, facial recognition results, audio / video call signals, and action recognition results.

[0048] The above technical solution includes an image acquisition module 111, an audio and video call signal acquisition module 112, a face recognition module 121, an audio and video call module 122, an operation behavior recognition module 123, and a display module 131. The face recognition module 121 and the operation behavior recognition module 123, through communication with the image acquisition module 111, can receive and recognize the image signals of the operators acquired by the image acquisition module 111 to obtain face recognition results and operation behavior recognition results. They then send the operator image signals, face recognition results, and operation behavior recognition results to the display module 131, which receives and displays these results, thus fulfilling the functions of face recognition and operator operation behavior recognition. The audio and video call module 122, through communication with the audio and video call signal acquisition module 112, can receive and transmit the audio and video call signals acquired by the module. The display module 131 receives and displays these signals, thus fulfilling the function of audio and video calls. In this way, face recognition, operation behavior recognition, and audio and video call functions are integrated into one, enriching the functions of the display screen and meeting people's diverse needs for display screen functions.

[0049] In this embodiment of the application, the safety monitoring display screen 100 may further include an image communication module 141, which communicates with the image acquisition module 111 to receive the image signal of the operator sent by the image acquisition module 111 and send the image signal of the operator to the face recognition module 121.

[0050] Understandable, such as Figure 2 As shown, the safety monitoring display screen 100 may also include an image communication module 141, which is used to receive the image signal of the operator sent by the image acquisition module 111 and perform face recognition on it.

[0051] Specifically, the image acquisition module 111 can acquire image signals of workers and send the acquired image signals to the image communication module 141. The image communication module 141 receives and sends the image signals of workers. The image communication module 141 can also upload the image signals of workers to the cloud for storage, and can also receive and send the image signals of workers stored in the cloud to the face recognition module 121, thereby enabling short-range or remote face recognition authentication to control the operating authority of construction machinery and thus improve the safety performance of construction machinery.

[0052] In this embodiment of the application, the image acquisition module 111 may include a camera.

[0053] It is understood that the image acquisition module 111 may include, but is not limited to, a camera. The camera is hardware on the safety monitoring display screen used to acquire image signals of the workers. The number of cameras may be one or more.

[0054] In this embodiment, the security monitoring display screen 100 may further include an alarm module 142, which communicates with the operation behavior recognition module 123 to receive alarm commands sent by the operation behavior recognition module 123 and issue alarm signals.

[0055] It is understandable that alarm module 142 can be a module used for alarm indication.

[0056] Specifically, the alarm module 142 communicates with the operation behavior recognition module 123. If the operation behavior recognition result obtained by the operation behavior recognition module 123 indicates that there is no safety hazard in the image signal of the operator, then no processing is performed or a non-action signal is sent to the alarm module 142. After receiving the non-action signal, the alarm module 142 maintains its original state. If the operation behavior recognition result indicates that there is a safety hazard in the image signal of the operator, then an alarm command is sent to the alarm module 142. The alarm module 142 receives the alarm command sent by the operation behavior recognition module 123 and issues an alarm signal. The operation behavior recognition module 123 can identify in real time whether there are safety hazards in the operation behavior of the operator operating the construction machinery, based on the image signal sent by the image acquisition module 111. Once the operation behavior recognition result is obtained, if the result indicates that there are safety hazards in the operation behavior of the operator operating the construction machinery, the operation behavior recognition module 123 will send an alarm command to the alarm module 142. After receiving the alarm command from the operation behavior recognition module 123, the alarm module 142 will sound an alarm to remind the operator or other safety monitors to adjust the control actions or take corresponding measures in a timely manner to ensure the safe operation of the construction machinery by the operator.

[0057] In this embodiment, the alarm module 142 may include an alarm indicator light and / or a buzzer.

[0058] It is understood that the alarm module 142 includes an alarm indicator light and / or a buzzer, wherein the alarm indicator light serves as hardware for visual alarm prompts, and similarly, the buzzer serves as hardware for audible alarm prompts.

[0059] Specifically, after receiving the alarm command sent by the operation behavior recognition module 123, the alarm module 142 will flash the alarm indicator light and / or sound the buzzer continuously to remind the operator or other safety monitor to adjust the control action or take corresponding measures in a timely manner to ensure the safe control of the construction machinery.

[0060] In this embodiment, the security monitoring display screen 100 may include multiple heat dissipation vents.

[0061] It is understandable that the heat dissipation vent is a hole on the safety display screen 100 used for heat dissipation.

[0062] Specifically, since the security monitoring display screen 100 generates a lot of heat during signal transmission, the heat can be dissipated in time through the heat dissipation vent, avoiding damage to the security monitoring display screen 100 due to high temperature and ensuring the normal operation of the security monitoring display screen 100.

[0063] like Figure 3As shown, a second aspect of this application provides a safety monitoring system 200 for construction machinery, which may include: an image acquisition device 210, installed on the construction machinery, for acquiring monitoring video signals related to the construction machinery; a safety monitoring display screen as described above; a terminal device 220; an audio / video call server 230, for transmitting and processing audio and video signals transmitted between the safety monitoring display screen and the terminal device; and a video playback server 240, for transmitting and processing monitoring video signals, and sending the processed monitoring video signals to the safety monitoring display screen.

[0064] It is understood that the image acquisition device 210 can be installed on construction machinery, such as the hook or drum of a tower crane, to acquire real-time monitoring video signals related to the construction machinery while workers are operating it. The terminal device 220 is the other end device for audio and video communication with the security monitoring display screen 100. The audio and video communication server 230 is used to transmit and process the audio and video signals transmitted between the security monitoring display screen 100 and the terminal device 220. The video playback server 240 is used to transmit and process the monitoring video signals and send the processed monitoring video signals to the security monitoring display screen.

[0065] Specifically, the number of image acquisition devices 210 can be one or more. These devices are used to acquire monitoring video signals related to construction machinery, such as monitoring video signals during construction machinery operation. Terminal devices 220 can be fixed terminal devices or mobile terminal devices. The audio / video call server 230 performs conventional signal processing on the audio and video signals, which will not be described in detail here. Similarly, the video playback server 240 processes the monitoring video signals using conventional signal processing methods, which will not be described in detail here either.

[0066] In this embodiment of the application, the safety monitoring system 200 may further include a temperature sensor, which is installed on the construction machinery to collect the ambient temperature of the environment where the construction machinery is located and / or the mechanical temperature of the construction machinery.

[0067] It is understood that the number of temperature sensors can be one or more, and there is no limitation here. Temperature sensors are sensors that collect temperature signals, such as infrared temperature sensors. They can be used to detect the ambient temperature of the environment in which construction machinery is located, and can also be used to detect the mechanical temperature of construction machinery, thereby avoiding prolonged operation of workers or construction machinery in high-temperature environments, so as to ensure the safety of workers and the mechanical performance of construction machinery.

[0068] In this embodiment of the application, the security monitoring system may also include lighting auxiliary devices.

[0069] It is understood that lighting auxiliary devices may include lighting devices such as fill lights or flashlights.

[0070] Specifically, in low light conditions, the image acquisition device 110 may encounter unclear images during image acquisition. The lighting auxiliary device can be used to increase illumination and improve image clarity.

[0071] This application also provides a construction machinery, which may include: the safety monitoring system for construction machinery as described above.

[0072] In one specific embodiment, the safety monitoring display screen includes an image acquisition module, an audio / video call signal acquisition module, a face recognition module, an audio / video call module, an operation behavior recognition module, and a display module. The face recognition module and the operation behavior recognition module, through communication with the image acquisition module, can receive and recognize the image signals of the workers acquired by the image acquisition module to obtain face recognition results and operation behavior recognition results, and send these results to the display module. The display module receives and displays the image signals, face recognition results, and operation behavior recognition results, thus fulfilling the functions of face recognition and worker operation behavior recognition. The audio / video call module, through communication with the audio / video call signal acquisition module, can receive and transmit the audio / video call signals acquired by the acquisition module. The display module receives and displays the audio / video call signals, thus fulfilling the audio / video call function. In addition, the safety monitoring display screen may also include an image communication module, which uploads and stores the image signals of the workers sent by the image acquisition module to the cloud, and sends the remotely uploaded image signals of the workers to the face recognition module to realize remote or short-range face recognition function. The safety monitoring display screen may also include an alarm module, which determines that there is a safety hazard in the current worker's operation by receiving alarm instructions sent by the operation behavior recognition module. The alarm module can promptly remind the current worker or other safety monitors to ensure the personal safety of the workers.

[0073] In summary, the technical solution provided in this application integrates audio and video call functions, facial recognition functions, and behavior recognition functions into one, which not only improves the monitoring of the safety performance of construction machinery, but also enriches the functions of the display screen and can meet people's diverse needs for display screen functions.
