[0004] Regarding monitors, in order to save power, existing monitors have a power-saving mode.

[0049] Referring to Figures 1-7, this embodiment provides a baby monitor with a power-saving mode and low-light full-color, including a camera unit 1 and a monitoring display unit 2 connected to the camera unit 1;

[0050] The monitoring and display unit 2 includes a display back-end load, a display communication module, and a first power controller 21. The display back-end load is connected to the display communication module and the first power controller 21 respectively. The display communication module is connected to the first power controller 21. The display communication module enters a sleep mode and / or the first power controller 21 controls the on / off of the power supply circuit of the display back-end load.

[0051] The camera unit 1 includes a camera communication module and a camera back-end load. The camera back-end load is connected to the camera communication module. The camera back-end load is used to acquire color images and transmit the acquired color images to the monitoring display unit 2 through the camera communication module.

[0052] In the above embodiments, the baby monitor with power-saving mode and low-light full-color display includes a camera unit 1 and a monitoring display unit 2 connected to the camera unit 1. The monitor can be used for various purposes, including but not limited to infants, the elderly, other special groups (patients, disabled persons, people with cognitive impairments), or pets. It can also be used in equivalent video intercoms (such as children's or adult video intercoms). The monitoring display unit 2 includes a display back-end load, a display communication module, and a first power controller 21. The display back-end load is connected to both the display communication module and the first power controller 21. The display communication module preferably uses an FHSS network, i.e., Frequency-Hopping Spread Spectrum. The Spectrum network displays a communication module with management and communication functions. It is connected to the first power controller 21. During the operation of the baby monitor with power-saving mode and low-light full-color mode, it can enter sleep mode according to system needs to reduce power consumption. The first power controller 21 is mainly responsible for controlling the on / off state of the power supply circuit for the back-end loads, which may include the display screen, related circuit modules, etc. By controlling the on / off state of the power supply circuits, the power can be cut off in time when certain functional modules are not needed, avoiding unnecessary power consumption. The camera unit 1 includes a camera communication module and a camera back-end load. The camera communication module preferably uses an FHSS network, i.e., Frequency-Hopping Spread Spectrum. The Spectrum network and camera communication module are important components of camera unit 1, used for data management and communication. It may include control chips and related circuits. On one hand, it connects to the camera backend load to receive image data captured by the camera; on the other hand, it interacts and manages data with other related components. The camera backend load can capture color images in low-light environments, and can be a typical camera device that switches between black and white and color modes based on ambient light intensity. It can also present color images even when the ambient visible light is very weak. Therefore, camera unit 1 preferably captures and forms color images. When color images are not needed, it can also capture and form black and white images. When the camera is a typical camera, it will be configured... A parameter is used to determine whether the camera operates in color or black-and-white image mode based on ambient light intensity (commonly referred to as entering night vision black-and-white mode and exiting night vision to enter color mode). The ambient light intensity parameter can be provided by the first illuminance sensor 119 or the first image acquisition sensor 122. The camera's backend load requires a weak visible light environment to display a color image. When the ambient light is below the level required to display color video, a night light module can supplement the environment with visible light, or other external visible light supplementary lighting devices can be used to ensure that the ambient light is sufficient to display color video. It utilizes advanced optical sensors and image processing technology to capture the color information of objects even in low-light conditions.The acquired image data is transmitted to the monitoring display unit 2 via the camera communication module. In this baby monitor with power-saving mode and low-light full-color display, camera unit 1 and monitoring display unit 2 are connected via corresponding communication modules to achieve image data transmission. Furthermore, monitoring display unit 2 can be used not only in full-color but also in common black and white display mode. The image information acquired by the camera's backend load can be accurately transmitted to monitoring display unit 2 for display.

[0053] The application of a camera backend load significantly improves the image acquisition capabilities of baby monitors with power-saving modes and low-light full-color capabilities in low-light environments. It can clearly capture color images in indoor environments at night, dimly lit corridors, or outdoor scenes before dawn. For scenarios requiring monitoring in low-light environments, such as nighttime monitoring of a nursery, it can more accurately observe the baby's condition, including the color of the baby's clothing and the color information of surrounding objects, providing users with a more realistic and detailed monitoring image. Compared to traditional cameras that can only capture black and white images in low-light environments, the camera backend load can better reproduce the color information of the monitored scene, helping users to more quickly and accurately identify the characteristics and state of the monitored object. For example, when monitoring a pet, changes in the pet's fur color can be seen more clearly, allowing for timely detection of any abnormalities. The sleep mode function of the display communication module in monitoring display unit 2 controls the on / off switching of the power supply circuit to the display backend load, and also controls the power supply circuit through the first power controller. The on / off control of the power supply circuit for the display back-end load 21 effectively reduces the overall power consumption of the baby monitor with power-saving mode and low-light full-color mode. During periods when real-time image display is not required, such as at night when most people are resting, the display communication module enters sleep mode. At this time, some internal circuit components stop working or enter a low-power state, greatly reducing power consumption. At the same time, the power supply to the back-end load can also be cut off by the first power controller 21 according to the actual situation. For example, when the display screen does not need to work, its power supply circuit can be disconnected in time to avoid continuous power consumption of the screen. For baby monitors with power-saving mode and low-light full-color mode that use battery power, it can significantly extend the battery life, reduce the number of charging times, and improve the convenience and economy of using baby monitors with power-saving mode and low-light full-color mode. At the same time, for users who use baby monitors with power-saving mode and low-light full-color mode for a long time, such as families that need to monitor the elderly or children for a long time, it can reduce the cost of use and is also more energy-saving and environmentally friendly.

[0054] Referring to FIG1, in one embodiment, the camera unit 1 includes a first power management component 12 and a second power controller 113, the camera back-end load includes a first camera load component 13 and a first management module 101, the camera communication module includes a first communication module 105, the second power controller 113 is connected to the first management module 101 and the first communication module 105 respectively, and the first management module 101 is connected to the first communication module 105, the first power management component 12 is connected to the second power controller 113, and the first camera load component 13 is connected to the second power controller 113 and the first management module 101 respectively.

[0055] In the above embodiments, the camera unit 1 includes a first power management component 12 and a second power controller 113. The camera back-end load includes a first camera load component 13 and a first management module 101. The first power management component 12 includes a first battery 112, a first charging manager 111, a first power manager 109, and a first power switch 130. The first battery 112 provides power to the camera unit 1 and is one of the energy sources for the entire camera unit 1. The first charging manager 111 is responsible for managing the charging process of the first battery 112 to ensure that the battery can be charged safely and efficiently. It is interconnected with the first power manager 109 and the first battery 112 to coordinate charging-related operations. The first power manager 109 can adjust and manage the input voltage and provide a suitable voltage. Different circuit modules are connected to the first charging manager 111, the first battery 112, and the first power switch 130, and are also connected to the preset power adapter 125 to perform reasonable power distribution when an external power source is connected. The first power switch 130 is used to control the power supply of the entire camera unit 1. When the camera unit 1 is not needed, the power switch can be turned off to save energy. The second power controller 113 plays the role of controlling power distribution in the camera unit 1. It is connected to the first power management component 12, receives power from the power management component, and distributes it according to the needs of different modules. At the same time, it is also connected to the first camera load component 13 and the first management module 101 and the first communication module 105 in the lens 11 to ensure that each module can work normally.

[0056] The first camera load component 13 includes a first memory 129, a first infrared fill light module 118, a first illuminance sensor 119, a first image acquisition sensor 122, and a first infrared light filter controller 128 connected in parallel. The camera unit 1 also includes a lens 11. The first memory 129 is used to store data related to the camera unit 1, such as configuration information and acquired image data. One end of it is connected to the second power controller 113 to obtain power, and the other end is bidirectionally connected to the first management module 101 through an SPI interface to realize data transmission and interaction. The first infrared fill light module 118 provides auxiliary lighting for image acquisition in low-light environments. It is powered by the second power controller 113 and connected to the first management module 101 through a GPIO interface for control according to ambient light conditions. The first illuminance sensor 119 is used to detect the ambient light intensity. It is connected to the ADC of the second power controller 113 and the first management module 101. The camera unit 1 is connected to the IN interface and transmits the detected light intensity information to the first management module 101 for corresponding control of the infrared fill light module, etc. The first image acquisition sensor 122 is one of the core components of the camera unit 1 and is used to acquire image information. It obtains power from the second power controller 113 and transmits image data unidirectionally to the first management module 101 through the DVP or MIPI interface. At the same time, it bidirectionally connects to the first management module 101 through the I2C interface to exchange some configuration and control information. The first infrared light filter controller 128 is connected to the first image acquisition sensor 122 and the first management module 101, and is also connected to the lens 11. It can control the switching of the infrared light filter according to the ambient light and image acquisition requirements to ensure that good image quality can be obtained under different lighting conditions. The camera unit 1 also includes a first button 121, which is connected to the GPIO interface of the first management module 101 and is used to put the camera device into pairing mode during pairing. Pairing includes pairing with monitor display devices, as well as pairing with smartphones, tablets and computers.

[0057] The camera communication module includes a first communication module 105. The second power controller 113 is connected to the first management module 101 and the first communication module 105 respectively. The first management module 101 (MCU) is the core control unit, which includes a first image processing module 102, a first processor 103, and a first controller 104. It is responsible for managing and coordinating the work of each module in the camera unit 1, processing image data, and controlling the operation of other modules. It is connected to the first communication module 105 to realize data communication and interaction. It is also connected to the first camera load component 13 and the second power controller 113 to control and transmit data to each module. The first communication module 105 is a wireless communication module with built-in SOC126 frequency hopping spread spectrum technology. It is mainly used to realize wireless communication between the camera unit 1 and other devices (such as the monitoring display unit 2). The composition of the first communication module 105 includes, but is not limited to, the following combinations: a module composed of a chip with built-in radio frequency, SOC126, and audio codec functions; a module composed of a chip with built-in radio frequency and SOC126... The module consists of two main chips: an integrated chip and an additional audio codec chip. Another module consists of two main chips: a chip with integrated audio codec and SOC126 and an additional RF chip. A third module consists of three main chips: an RF chip, an additional SOC126 chip, and an additional audio codec chip. This embodiment uses an example of an RF module consisting of two main chips: a chip with integrated RF and SOC126 and an additional audio codec chip. This module is connected to the first management module 101 to receive and transmit relevant data. In the entire camera unit 1, all components are closely connected and cooperate with each other. The first power management component 12 provides a stable power supply to the entire unit, and the second power controller 113 rationally distributes power. Each module in the first camera load component 13 performs its respective function under the control of the first management module 101, such as acquiring images, detecting light intensity, and providing auxiliary lighting. The lens 11 manages and communicates data, ensuring that image data can be accurately transmitted to other devices.

[0058] When there is no video request, the first communication module 105 controls the second power controller 113 to disconnect power to the back-end load via GPIO. At this time, the camera only provides audio and temperature data to the monitor display device. When the first communication module 105 receives a video request signal from the monitor display device, it controls the second power controller 113 to supply power to the back-end load via GPIO. At this time, the peripheral circuits of the back-end load enter the working state to complete video output. When the first communication module 105 receives a no-video-request signal again, it controls the second power controller 113 to disconnect power to the back-end load via GPIO. This cycle repeats. Therefore, during operation, disconnecting the power supply to the back-end load controlled by the second power controller 113 when there is no video request saves power consumption. The first power management component 12, through reasonable connection and control, can ensure the first battery 112... Safe charging and efficient use of electrical energy are ensured. Meanwhile, the first power switch 130 allows users to control the power supply of the camera unit 1, saving energy. The second power controller 113 can flexibly allocate power according to the needs of different modules, improving the efficiency of power utilization. The first image acquisition sensor 122 can accurately acquire image information. Together with the first infrared light filter controller 128 switching under different lighting conditions, the first illuminance sensor 119 detecting the ambient light intensity, and the first infrared supplementary light module 118 providing auxiliary lighting when the light is insufficient, high-quality images can be obtained in various environments. The first management module 101 in the camera communication module can efficiently manage and process image data. The first communication module 105 realizes wireless communication with other devices, ensuring that image data can be transmitted to the monitoring display unit 2 in a timely and accurate manner, providing users with real-time monitoring images.

[0059] Referring to FIG1, in one embodiment, the camera unit 1 includes a second camera load component 14 and a third camera load component 15. The first power management component 12 is connected to the second camera load component 14 and the third camera load component 15 respectively, and the second camera load component 14 and the third camera load component 15 are connected in parallel to the first communication module 105.

[0060] In the above embodiments, the camera unit 1 includes a second camera load component 14 and a third camera load component 15. The second camera load component 14 includes a first audio signal processing module 127, a first microphone 107, and a first speaker 106. The first audio signal processing module 127 is an important module for processing audio signals. It obtains power from the first power switch 130 of the first power management component 12 and has the ability to bidirectionally connect to the first communication module 105 for transmitting and receiving audio-related data. Its main function is to convert and process the sound signal collected by the first microphone 107 to meet the requirements of transmission and playback, and to drive the first speaker with the received audio signal. The first microphone 107, acting as a sound acquisition device, converts ambient sound into electrical signals and transmits them to the first audio signal processing module 127. The first speaker 106, connected to the first audio signal processing module 127, converts the processed audio signals into sound and plays them out, thus achieving the sound playback function. The third camera load assembly 15 includes a first temperature sensor 116, a first night light module 117, and a first motor control module 108 connected in parallel. The first temperature sensor 116 detects the temperature of the environment surrounding the camera unit 1; one end of it is connected to the first power switch 130 to obtain power, and the other end is connected to the ADC of the first communication module 105. The IN interface is used to transmit the detected temperature data to the relevant modules for processing and analysis. The first night light module 117 provides illumination around the camera unit 1 in low-light environments. It is powered by the first power switch 130 and connected to the first communication module 105 via the GPIO interface, allowing it to be controlled according to actual needs, such as switching on and off and adjusting brightness. The first motor control module 108 is mainly used to control the motor equipment related to the camera unit 1. For example, it may be used to control the rotation direction or angle of the camera. It obtains power from the first power switch 130 and is connected to the first communication module 105 via the GPIO interface to receive control commands to achieve corresponding actions.

[0061] The first power switch 130 plays a crucial role in power distribution within the entire structure. It is connected to both the second camera load assembly 14 and the third camera load assembly 15, providing them with the necessary power. The first audio signal processing module 127 in the second camera load assembly 14 is bidirectionally connected to the first communication module 105, enabling effective transmission of audio data between this module and other related modules. The first microphone 107 and the first speaker 106 are sequentially connected to the first audio signal processing module 127, forming a complete audio acquisition and playback link. The first temperature sensor 116, the first night light module 117, and the first motor control module 108 in the third camera load assembly 15 are connected to the first power switch 130 and the first communication module 105 through their respective interfaces. The first temperature sensor 116 transmits temperature data through the ADC IN interface, the first night light module 117 transmits control signals through the GPIO interface, and the first motor control module 108 also transmits control signals through the GPIO interface. The interface receives control commands, and the second camera load component 14 and the third camera load component 15 are connected in parallel to the first communication module 105. This connection method ensures that they can independently perform their functions while sharing the data transmission channel of the first communication module 105, ensuring the coordinated operation of the entire camera unit 1 system. Therefore, when the first communication module 105 controls the monitor to enter the low power mode, the first camera load component 13 and the first management module 101 stop operating, while the second camera load component 14 and the third camera load component 15 are powered by the first power switch 130, so that they can still maintain normal operation, effectively saving power consumption and achieving the purpose of power saving.

[0062] The combination of the first audio signal processing module 127, the first microphone 107, and the first speaker 106 enables the camera unit 1 to acquire and play audio.

[0066] The second power manager 209, serving as the core of the power supply, is connected to the fourth and fifth camera load components 17. Each component in the fourth camera load component 16 is connected to the second power manager 209 and the second management module 201 through its respective interface. Specifically, the third power controller 214 and the second infrared fill light module 218 are connected to the second management module 201 via GPIO interfaces; the second memory 229 is connected via an SPI interface; the second illuminance sensor 219 is connected via an ADC IN interface; the second image acquisition sensor 222 is connected via a DVP or MIPI and I2C interface; and the second infrared filter controller 228 is connected to the second image acquisition sensor 222 and the second management module 201, and also to the lens 11.

The fourth and fifth camera load components 17 are connected in parallel to the second management module 201 and the second communication module 205, so that the components can work together, share the communication channel, and achieve efficient data transmission and function implementation.

[0067] In terms of power management, flexible and efficient power distribution is achieved through the settings of multiple power controllers and managers, which can adapt to the working needs of different components, reduce overall power consumption, extend battery life, or reduce energy consumption. In terms of image acquisition, the equipped camera back-end load and related image acquisition sensors and filter controllers enable the acquisition of high-quality color images under various lighting conditions, better restore the monitoring scene, and help accurately identify the monitored objects. At the same time, the audio processing function and environmental monitoring function (such as temperature and light intensity monitoring), as well as the controllable night light module and motor control module, not only enrich the functions of the baby monitor with power saving mode and low light full color, but also improve its adaptability to different environments and the comprehensiveness of monitoring, providing users with a more convenient and practical monitoring experience.

[0068] Referring to Figures 2 and 7, in one embodiment, the fourth camera load component 16 includes a WIFI module 215, which is connected to the second power manager 209 via a third power controller 214, and is also connected to the second management module 201.

[0069] In the above embodiments, the fourth camera load component 16 includes a WIFI module 215, which is a module that realizes wireless communication function. It enables the camera unit 1 to conduct wireless data transmission with other devices (such as the monitoring display unit 2 or external network devices), expanding the application scope and flexibility of the baby monitor with power saving mode and low light full color. The third power controller 214 is mainly responsible for controlling the power supply of the WIFI module 215. It obtains power from the second power manager 209 and provides appropriate power supply to the WIFI module 215 as needed to ensure the normal operation of the WIFI module 215. The second power manager 209 manages and distributes the power supply of the camera unit 1 as a whole. It provides power to the third power controller 214, thereby indirectly powering the WIFI module 215, and also providing power support to other components. The second power manager 209 serves as the core of the power supply and is connected to the third power controller 214. One end of the third power controller 214 is connected to the second power manager 209, and the other end is connected to the WIFI module 215 to supply power to the WIFI module 215. The WIFI module 215 is also connected to the USB or SDIO interface of the second management module 201, and performs data transmission and interaction with the second management module 201 through this interface, thereby realizing the collaborative work with the entire camera unit 1.

[0070] The introduction of the WIFI module 215 breaks the limitations of wired connections, allowing remote activation or deactivation of the camera's WIFI function. Control commands are sent from the frequency-hopping spread spectrum module of the monitoring display unit 2 to the camera unit 1 to turn the power supply on or off the WIFI module, thus controlling the WIFI function. Alternatively, control commands can be sent from other devices on the same frequency-hopping spread spectrum network that also have frequency-hopping spread spectrum modules to the camera unit 1 to turn the power supply on or off the WIFI module, enabling remote activation or deactivation of the WIFI function. This eliminates the inconvenience of requiring users to physically touch the camera to activate or deactivate the WIFI function. It allows the baby monitor with power-saving mode and low-light full-color to interact more flexibly with other devices, ensuring stable communication connections in complex wiring environments or scenarios requiring mobile monitoring. This significantly improves the applicability and convenience of the baby monitor with power-saving mode and low-light full-color.

[0071] Referring to Figure 3, in one embodiment, the monitoring and display unit 2 includes a second power management component 22, the display back-end load includes a first display load component 23 and a third management module 401, the display communication module includes a third communication module 405, the first power controller 21 is connected to the third management module 401 and the third communication module 405 respectively, and the third management module 401 is connected to the third communication module 405, the second power management component 22 is connected to the first power controller 21, and the first display load component 23 is connected to the first power controller 21 and the third management module 401 respectively.

[0072] In the above embodiment, the monitoring and display unit 2 includes a second power management component 22, and the display back-end load includes a first display load component 23 and a third management module 401. The second power management component 22 includes a third power manager 409, a third charging manager 411, and a third battery 412. The third power manager 409 is responsible for managing and distributing power to ensure that each component receives appropriate voltage and current. It is connected to the third charging manager 411 and the first power controller 21, and is also connected to a preset power adapter 125 to perform reasonable power allocation when an external power source is available. The main function of the third charging manager 411 is to manage the charging process of the third battery 412. It is connected to the third power manager 409. The power manager 409 and the third battery 412 are interconnected, and can control the charging rate and method according to the battery status and needs to ensure safe and efficient charging of the battery. The third battery 412 is the backup power source for the monitoring display unit 2. When there is no external power adapter 125, it provides power to the entire monitoring display unit 2. It forms a complete charging and power supply loop with the third charging manager 411 and the third power manager 409. The first display load component 23 includes a third memory 429 and a first display screen 422. The third memory 429 is used to store data related to the monitoring display unit 2, such as display settings and historical records. One end of it is connected to the first power controller 21 to obtain power, and the other end is connected via SPI. The interface is bidirectionally connected to the third management module 401 to realize data transmission and interaction; the first display screen 422 is the core component for displaying images and information. It obtains power from the first power controller 21, and receives image data for display through a one-way connection to the third management module 401 via the DVP or MIPI interface. At the same time, it is bidirectionally connected to the third management module 401 via the PWM interface to control parameters such as the brightness of the display screen; the monitoring display unit 2 also includes a fourth button 421. The fourth button 421 is connected to the GPIO interface of the third management module 401 to complete the control and operation of the display device. The number of fourth buttons 421 can be N+1 (N= or>0).

[0073] When the first display screen 422 is in the on-screen working state, the user can press the fifth button 416 once. At this time, the GPIO of the third communication module 405 will output a control signal to the first power controller 21 to disconnect the power supply to the back-end load. At this time, the back-end load of the power controller, including the first display screen 422, will be completely powered off and will not work, thus saving power. If the user wants to turn on the screen or view the video when the screen is off, he / she can press the fifth button 416 again. At this time, the GPIO of the third communication module 405 will output a control signal to the first power controller 21 to supply power to the back-end load to complete the video signal processing and turn on the screen.

[0074] When the first display screen 422 is in the off state, the third communication module 405 receives a control signal from the same frequency hopping spread spectrum network camera device to trigger the screen to light up, or receives audio and data. After the third communication module 405 analyzes and judges that the conditions for triggering the screen to light up are met, the third communication module 405 will output a control signal through GPIO to enable the first power controller 21 to supply power to the back-end load, so that the back-end load enters the working state to complete the corresponding video and data display.

[0075] When the first display screen 422 is in the on-screen working state, in addition to manually turning off the first display screen 422 by pressing the fifth button 416, the back-end load of the first power controller 21 can also be powered off and stopped working by setting a timer. The working process is as follows: a timer is set in the third communication module 405. When the first display screen 422 is in the on-screen working state, if there is no button operation and no control signal or data from the same frequency hopping spread spectrum network camera device to trigger the screen-on condition, the timer will count down to the set time. After that time, the third communication module 405 will output a control signal to the first power controller 21 through GPIO to disconnect the power supply to the back-end load, so that the back-end load does not work and saves power. (The timer is set to N, where N is greater than or equal to 1.)

[0076] The display communication module includes a third communication module 405. The first power controller 21 is connected to the third management module 401 and the third communication module 405 respectively. The third management module 401 (MCU) is the core control unit of the monitoring display unit 2, containing a third processor 403 and a third controller 404. It is responsible for managing and coordinating the work of various modules within the monitoring display unit 2, processing received data, and controlling the operation of other modules. It is connected to the first power controller 21, the third communication module 405, and the first display load component 23, etc., to control and transmit data to various modules. The third communication module 405 is a wireless communication module with built-in SOC126 frequency hopping spread spectrum technology. The third communication module 405 communicates with the camera device via frequency hopping spread spectrum wireless signals, transmitting audio, video, and data. It also controls and acquires signals from the external connection circuit module, and manages and controls the power-saving mode. The third communication module 405 can be composed of, but is not limited to, the following combinations: a module consisting of a chip integrating RF, SOC126, and audio codec functions; a module consisting of a chip integrating RF and SOC126 functions, plus an external audio codec chip; a module consisting of a chip integrating audio codec and SOC126 functions, plus an external RF chip; and a module consisting of a chip integrating RF and SOC126 functions, plus an external RF chip. The module consists of three main chips: an SOC126 chip and an audio codec chip. In this embodiment, the example uses a third communication module 405, consisting of a chip integrating RF and SOC126, and an audio codec chip. This module is primarily used for wireless communication between the monitoring display unit 2 and other devices (such as the camera unit 1). It is connected to the third management module 401 to receive and send relevant data. The third power manager 409 in the second power management component 22 serves as the power management core, connected to the third charging manager 411 and the first power controller 21, and also connected to the external power adapter 125. 11 is connected to the third battery 412 to form a charging circuit. The third memory 429 and the first display screen 422 in the first display load component 23 are respectively connected to the first power controller 21 and the third management module 401 through corresponding interfaces. The third management module 401 in the display communication module is connected to the first power controller 21 and the third communication module 405. The third management module 401 is also connected to the third memory 429 and the first display screen 422 in the first display load component 23. The third communication module 405 is connected to the third management module 401 to realize data transmission and communication functions. Through these connections, the various components of the entire monitoring display unit 2 work together to realize image display and related functions.

[0077] The design of the second power management component 22 ensures stable power supply and efficient management. The third power manager 409 can reasonably allocate the power from the external power source and the battery, and can regulate and manage the input voltage, providing appropriate voltage to different circuit modules. The third charging manager 411 ensures safe battery charging, providing stable power to the monitoring display unit 2 whether there is an external power source or battery power, avoiding equipment failure due to power problems. The third memory 429 can effectively store relevant data, supporting the normal operation of the monitoring display unit 2. The first display screen 422, through reasonable connection with the third management module 401, can accurately display images and information, and can conveniently control brightness through the PWM interface to adapt to different ambient light conditions, improving display effect and user experience. The third management module 401 and the third communication module 405 in the display communication module realize convenient communication and effective control between the monitoring display unit 2 and other devices, can receive and send data in a timely manner, ensuring the real-time and accuracy of monitoring information, and also facilitating user operation and settings of the monitoring display unit 2.

[0078] Referring to FIG3, in one embodiment, the monitoring display unit 2 further includes a second display load component 24 and a third display load component. The second power management component 22 is connected to the second display load component 24 and the third display load component respectively, and the second display load component 24 and the third display load component are connected in parallel to the third communication module 405.

[0079] In the above embodiment, the monitoring display unit 2 further includes a second display load component 24 and a third display load component. The second display load component 24 includes a second audio signal processing module 427, a third microphone 407, and a third speaker 406. The second audio signal processing module 427 is a key component for processing audio signals. It obtains power from the third power manager 409 of the second power management component 22, is bidirectionally connected to the third communication module 405 for transmitting audio data, and is also connected to the third microphone 407 and the third speaker 406. It can process the sound collected by the third microphone 407 to make it suitable for transmission and playback, and can receive external audio signals to drive the third speaker 406 to emit sound. The third microphone 407 is used to collect ambient sound signals, convert the sound into electrical signals, and transmit them to the second audio signal processing module 427. The third speaker 406 receives the processed audio signal from the second audio signal processing module 427 and converts it into sound for playback. The third display load component is a first sound pressure level indicator 417. The first sound pressure level indicator 417 is used to display relevant sound information, such as sound intensity, and is connected to the GPIO of the third communication module 405. The interface receives relevant signals to control its on / off state or flashing frequency.

[0080] The third power manager 409, as the core power supply component, is connected to both the second and third display load components. In the second display load component 24, the second audio signal processing module 427 is bidirectionally connected to the third communication module 405, forming an audio data transmission channel. It is also sequentially connected to the third microphone 407 and the third speaker 406, constituting a complete audio acquisition and playback link. The first sound pressure level indicator 417 in the third display load component is connected to the GPIO interface of the third communication module 405. Furthermore, the monitoring display unit 2 includes a fourth button 421, a fifth button 416, and an eighth button 408, which are respectively connected to the GPIO interfaces of the third management module 401 and the third communication module 405. The interface is used by the user to operate and control the relevant functions. The second display load component 24 and the third display load component are connected in parallel to the third communication module 405, so that the third communication module 405, the second display load component 24 and the third display load component are powered by the third power manager 409. This connection method allows them to share the data transmission channel of the third communication module 405, while also being able to independently realize their respective functions, ensuring the coordinated operation of the audio and indicator functions of the entire monitoring display unit 2.

[0081] The video display processing circuit is completed by the third management module 401 and the first display screen 422, and their power supply is controlled by the first power controller 21. The audio signal processing is completed by the third communication module 405 and the second audio signal processing module 427. There are three modes: first, when audio and video work simultaneously, that is, all circuit modules are powered on (this working mode is called "standard mode", and the working mode can be defined by any name); second, when the user does not watch video but wants to listen to the sound in real time (this working mode is called "audio monitoring mode", and the working mode can be defined by any name); and third, when the user does not watch video or listen to the sound, the third communication module 405 enters sleep mode and disconnects the power supply to the back-end load through the first power controller 21 to reduce power consumption (this working mode is called "ECO mode", and the working mode can be defined by any name).

[0082] When the monitor display device is set to the power-saving mode of "audio monitoring mode", it can continuously listen to the sound from the camera device and send audio to the camera device. The fifth button 416 can be used to switch the video display on and off. When the video display is off, the GPIO of the third communication module 405 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load third management module 401, memory and LCD display to achieve power saving. If no button is operated on the monitor display device and / or no trigger wake-up signal is received from the camera device within a preset time, the GPIO of the third communication module 405 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load and turn off the video, only retaining the audio function. Therefore, it is called "audio monitoring power-saving mode".

[0083] When the monitor display device is set to the ultra-power-saving "ECO mode", the audio and video functions can be switched on and off using the fifth button 416. When the audio and video functions are off, the GPIO of the third communication module 405 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load third management module 401, memory and LCD display. Then the third communication module 405 will enter sleep mode. After the third communication module 405 enters sleep mode, the user can wake up the third communication module 405 at any time by operating the fifth button 416. After waking up, all circuits will be restored to power and enter the working state to complete the display or transmission of audio, video and data. In addition, if the third communication module 405 receives a signal from the same frequency hopping spread spectrum network camera device to trigger the wake-up of the monitor display device (the wake-up signal here includes but is not limited to audio data, ambient temperature, ambient illuminance, ambient humidity, heart rate, blood oxygen, respiratory rate, body temperature, snoring, movement, rolling, falling, sleeping posture, standing posture, sitting posture, switch status), the third communication module 405 will also wake up and put all circuits into working state to complete the display or transmission of audio, video and data.

[0084] Therefore, this embodiment addresses the user's needs when they sometimes only need audio functionality and do not require video viewing (which we call "audio with power-saving mode and low-light full-color baby monitor"), and sometimes do not need both video and audio functionality (which we call "ECO mode"). By controlling the first power controller 21 and the third communication module 405 to enter sleep mode through the third communication module 405, overall power consumption is reduced to achieve ultra-low power consumption. When the third communication module 405 controls the first power controller 21 to enter low-power mode, the first display load component 23 and the third management module 401 stop operating, while the second display load component 24 and the third display load component can still maintain normal operation with audio input and output, effectively saving power consumption and achieving the goal of power saving.

[0085] The inclusion of the second audio signal processing module 427, the third microphone 407, and the third speaker 406 enables the monitoring display unit 2 to acquire and play audio. Users can hear sounds from the monitored area and hear alerts through the speaker, which is highly practical in monitoring scenarios. This enhances the functionality of the baby monitor with power-saving mode and low-light full-color display. The first sound pressure level indicator 417, connected to the third communication module 405, displays sound-related information, allowing users to intuitively understand sound intensity and other conditions, providing more information dimensions for monitoring. The fourth button 421 connects to the GPIO interface of the third management module 401, and the fifth button 416 and the eighth button 408 connect to the GPIO interface of the third communication module 405, facilitating user operation of related functions. Users can easily control audio playback, sound pressure level indicator display, and other functions through the buttons, improving ease of use and user experience.

[0087] In the above embodiment, the monitoring display unit 2 includes a third power management component 26, and the display back-end load includes a fourth display load component 27 and a fourth management module 501. The third power management component 26 includes a fourth power manager 509, a fourth charging manager 511, and a fourth battery 512. The fourth power manager 509 is mainly responsible for managing and distributing the power supply to the monitoring display unit 2, and can adjust and manage the input voltage, providing appropriate voltage to different circuit modules. It is connected to the fourth charging manager 511 and the first power controller 21, and also connected to a preset power adapter 125. This allows for the rational allocation of electrical energy when an external power source is available, ensuring that each component receives appropriate voltage and current. The fourth charging manager 511 manages the charging process of the fourth battery 512. It is interconnected with the fourth power manager 509 and the fourth battery 512, and can control the charging rate and method according to the battery's status and needs, ensuring safe and efficient charging of the battery. The fourth battery 512 serves as a backup power source for the monitoring and display unit 2, providing power to the entire unit when there is no external power adapter 125. It, along with the fourth charging manager 511 and the fourth power manager 509, forms a complete charging and power supply circuit. The fourth display load component 27 includes a fourth memory 529 and a second display screen 522. The fourth memory 529 is used to store data related to the monitoring display unit 2, such as display settings and historical records. One end of it is connected to the first power controller 21 to obtain power, and the other end is bidirectionally connected to the fourth management module 501 through the SPI interface to realize data transmission and interaction. The second display screen 522 is the core component for displaying images and information. It obtains power from the first power controller 21, and receives image data for display through a one-way connection to the fourth management module 501 through the DVP or MIPI interface. At the same time, it is bidirectionally connected to the fourth management module 501 through the PWM interface to control parameters such as the brightness of the display screen.

[0088] The display communication module includes a fourth communication module 505. The first power controller 21 is connected to the fourth management module 501 and the fourth communication module 505. The fourth management module 501, as the core control unit of the monitoring display unit 2, includes a fourth processor 503 and a fourth controller 504. It is responsible for managing and coordinating the work of various modules within the monitoring display unit 2, processing received data, and controlling the operation of other modules. It is connected to the first power controller 21, the fourth communication module 505, and the fourth display load component 27, etc., to control and transmit data to various modules. The fourth communication module 505 (with a built-in SOC 126 in the RF module) is mainly used to realize wireless communication between the monitoring display unit 2 and other devices (such as the camera unit 1). It is connected to the fourth management module 501 to receive and send relevant data information. The fourth power manager 509 in the third power management component 26, as the core of power management, is connected to the fourth charging manager 511 and the first power controller 21, and is also connected to the external power adapter 125. The fourth charging manager 511 is connected to the fourth battery 512 to form a charging circuit. The fourth memory 529 and the second display screen 522 in the fourth display load component 27 are respectively connected to the first power controller 21 and the fourth management module 501 through corresponding interfaces. The fourth management module 501 in the display communication module is connected to the first power controller 21 and the fourth communication module 505. The fourth management module 501 is also connected to the fourth memory 529 and the second display screen 522 in the fourth display load component 27. The fourth communication module 505 is connected to the fourth management module 501 to realize data transmission and communication functions. In addition, the monitoring display unit 2 also includes a sixth button 516 and a seventh button 521, which are respectively connected to the GPIO interface of the fourth communication module 505 and the GPIO interface of the fourth management module 501 for users to operate and control related functions. Through these connections, the various components of the entire monitoring and display unit 2 work together to achieve image display and related functions. The monitoring and display unit 2 also includes a sixth button 516 and a seventh button 521. The sixth button 516 is connected to the GPIO interface of the fourth communication module 505, and the seventh button 521 is connected to the GPIO interface of the fourth management module 501. Therefore, when the fourth communication module 505 controls the first power controller 21 to enter the low-power mode, the fourth display load component 27 and the fourth management module 501 stop operating and there is no audio input or output, effectively saving power consumption and achieving the purpose of power saving.

[0089] The third power management component 26 ensures that the monitoring display unit 2 receives stable power under different power supply conditions. The fourth power manager 509 rationally allocates external power and battery power, and the fourth charging manager 511 ensures safe battery charging. Whether using an external power adapter 125 or battery power, it can avoid equipment failure caused by power problems, providing a solid foundation for the stable operation of the monitoring display unit 2. The fourth memory 529 can effectively store relevant data, supporting the normal operation of the monitoring display unit 2. The second display screen 522, through a reasonable connection with the fourth management module 501, can accurately display images and information, and can conveniently control brightness through the PWM interface to adapt to different ambient light conditions, improving display effect and user experience. The fourth management module 501 and the fourth communication module 505 in the display communication module realize convenient communication and effective control between the monitoring display unit 2 and other devices, and can receive and send data in a timely manner, ensuring the real-time and accuracy of monitoring information. At the same time, the sixth button 516 and the seventh button 521 facilitate user operation of relevant functions, improving ease of use and user experience.

[0090] Referring to FIG4, in one embodiment, the fourth display load component 27 includes a second sound pressure level indicator 517, one end of which is connected to the first power controller 21 and the other end is connected to the fourth management module 501. The monitoring display unit 2 also includes a fourth microphone 507 and a fourth speaker 506, and the fourth microphone 507 and the fourth speaker 506 are respectively connected to the fourth management module 501.

[0091] In the above embodiment, the fourth display load component 27 includes a second sound pressure indicator light 517, which is used to intuitively display relevant information about sound, such as the intensity of sound. One end of the light is connected to the first power controller 21 to obtain power, and the other end is connected to the fourth management module 501. The fourth management module 501 receives and processes relevant signals to control the light's on / off state or flashing frequency, thereby providing visual feedback on sound intensity to the user. The monitoring display unit 2 also includes a fourth microphone 507 and a fourth speaker 506. The fourth microphone 507 is a device for collecting ambient sound. It converts sound signals into electrical signals and transmits them to the fourth management module 501 for further processing. The fourth speaker 506 converts the electrical signal processed by the fourth management module 501 into sound and plays it out, thus realizing the sound playback function. The first power controller 21 provides power to the second sound pressure level indicator 517, the fourth microphone 507, and the fourth speaker 506. The second sound pressure level indicator 517 is connected to the fourth management module 501 to receive control signals to display sound-related information. The sound signal collected by the fourth microphone 507 is transmitted to the fourth management module 501. After processing the signal, the fourth management module 501 transmits it to the fourth speaker 506 for playback, so that the various components work together to realize the integration of sound acquisition, processing, and display functions.

[0092] The processing of video display and audio functions is completed by the fourth management module 501 and the second display screen 522, and their power supply is controlled by the first power controller 21. Firstly, in the mode where audio and video work simultaneously, all circuit modules are powered and in operation (this working mode is called "standard mode", and the working mode here can be defined by any name). Secondly, when the user is not watching video or listening to sound, the fourth communication module 505 enters sleep mode and disconnects the power supply to the back-end load through the first power controller 21 to reduce power consumption (this working mode is called "ECO mode", and the working mode here can be defined by any name).

[0093] When the monitor display device is set to the ultra-power-saving "ECO mode", the audio and video functions can be switched on and off using the sixth button 516. When the audio and video functions are off, the GPIO of the fourth communication module 505 will output a signal to control the first power controller 21 to disconnect the power supply to the back-end load, the fourth display load component 27, and the fourth management module 501. Then, the fourth communication module 505 will enter sleep mode. After the fourth communication module 505 enters sleep mode, the user can wake up the fourth communication module 505 at any time by operating the sixth button 516. After waking up, all circuits will be restored to power and enter the working state to complete the display or transmission of audio, video, and data. In addition, if the fourth communication module 505 receives a signal from the same frequency-hopping spread spectrum network camera device to trigger the wake-up of the monitor display device (the wake-up signal here includes, but is not limited to, audio data, ambient temperature, ambient illuminance, ambient humidity, heart rate, blood oxygen, respiratory rate, body temperature, snoring, movement, rolling, falling, sleeping posture, standing posture, sitting posture, and on / off status), the fourth communication module 505 will also wake up and put all circuits into working state to complete the display or transmission of audio, video, and data.

[0094] Therefore, this invention addresses the user's need to sometimes not view video and audio functions (what we call "ECO mode"). It reduces overall power consumption by controlling the first power controller 21 and the fourth communication module 505 to enter sleep mode via the fourth communication module 505, achieving ultra-low power consumption. The second sound pressure indicator 517, connected to the first power controller 21 and the fourth management module 501, can display real-time sound intensity and other information, allowing users to intuitively understand the sound situation in the monitored area without relying on auditory perception. This provides a more convenient sound monitoring method, especially in noisy environments or scenarios requiring silent monitoring. The fourth microphone 507 and the fourth speaker 506 enable the monitoring display unit 2 to have audio acquisition and playback functions. Users can hear the sounds in the monitored area and can also hear prompts through the speaker, enhancing the practicality and functionality of the baby monitor with power-saving mode and low-light full-color display, providing more comprehensive information for the monitoring scenario.

[0095] Referring to FIG5, in one embodiment, the image processing module in the camera communication module includes an image signal processor 131, a video processor 132 and a video encoder 133. One end of the image signal processor 131 is connected to the image acquisition sensor of the camera unit 1, and the other end is connected to the video processor 132. The video processor 132 is connected to the video encoder 133.

[0096] In the above embodiments, the image processing module in the camera communication module includes an image signal processor 131, a video processor 132, and a video encoder 133. The image processing module comprises a first image processing module 102 and a second image processing module 202. The image acquisition sensors of the camera unit 1 are a first image acquisition sensor 122 and a second image acquisition sensor 222. The image signal processor 131 is the front-end of the image processing, connected to the image acquisition sensor at one end to receive the raw image signal. It performs preliminary processing on the signal acquired by the image acquisition sensor, such as amplification and noise reduction, to improve image quality. The video processor 132 is located after the image signal processor 131. It receives the processed signal from the image signal processor 131 and performs video processing... The frame rate, resolution, and other parameters are adjusted, and color correction and other processing may be performed to further optimize the video image. The video encoder 133 is connected to the video processor 132. It encodes the video data processed by the video processor 132 and converts it into a format suitable for transmission and storage, so that it can be transmitted between different devices or stored locally. The image signal acquired by the image acquisition sensor is first transmitted to the image signal processor 131. The image signal processor 131 processes the signal and then transmits it to the video processor 132. The video processor 132 further processes the video and then transmits the data to the video encoder 133. This ensures an orderly processing process of the image from acquisition to final encoding. Each step gradually improves and optimizes the image quality to meet the requirements of the monitoring system.

[0097] The selection of key components in the image processing module aims to enhance image brightness. A high-sensitivity image sensor and a large-aperture lens are employed to maximize light intake and improve image brightness. During operation, a weak visible light environment is required. People or objects in front of the camera are reflected through the large-aperture lens and identified by the high-sensitivity image sensor, then transmitted to the image processing module. The internal ISP image signal processor 131 then processes the following:

[0098] With the dynamic gain set to maximum, there will be a lot of noise and dead pixels. This is then addressed by adjusting 3D noise reduction to remove noise and dead pixels. Next, the video frame rate is reduced to extend the exposure time of each frame, thus increasing the AE exposure value and improving brightness. Since the reduced frame rate and extended AE exposure time will produce motion blur, the ISO value is increased, and the frame rate and AE exposure time are repeatedly adjusted to find an optimal balance. Finally, automatic white balance (AWB) adjustment, color correction, and optimization are performed to achieve the best image reproduction and color effect.

[0099] The image and video data after color restoration, processed by the image signal processor 131, are transmitted to the video processor 132 for further partitioning and processing of each block individually. This secondary optimization of the partitioned blocks is as follows:

[0100] First, the video data is converted into a YUV format image and the YUV image signal is amplified. Then, the image is divided into N+1 (N= or > 0) small blocks of 16x16 pixels each, and each small block is optimized individually. After partitioning, each block will have its gain adjusted according to its state to increase the brightness and color saturation of each block. Then, the noise generated by automatic gain adjustment is suppressed and blurred through parameter adjustment. Then, the object is delineated using an edge algorithm. Finally, the snow noise caused by the brightness and color saturation of each block due to gain adjustment is blurred and the edges are sharpened, so that the image restoration, brightness and color effect are optimized to achieve low-light full-color image and video. The completed image and video are transmitted to the encoder to complete the video encoding and then sent to each channel for use by the backend.

[0101] Through sequential processing by the image signal processor 131, video processor 132, and video encoder 133, the acquired images can be optimized in various ways, including noise reduction, color correction, frame rate and resolution adjustment, thereby significantly improving image quality. The video encoder 133 converts the processed video data into a suitable format, which is convenient for transmission and storage between different devices, improving the universality and adaptability of the data, and ensuring that the monitoring images can be displayed and used normally on various devices.
