[0036] In the fields of smart homes, remote monitoring, and communications, with the rapid development of wireless communication, image processing, and audio processing technologies, people's demand for long-distance real-time communication, monitoring, and video intercom is increasing. Traditional wired video intercom systems are limited by problems such as complex wiring, inconvenient installation, and poor scalability, making it difficult to meet the flexibility and convenience requirements of modern homes and commercial spaces.

[0037] Existing wireless communication technologies, such as Wi-Fi and Bluetooth, have made wireless video intercom possible.

In particular, miniaturization, low power consumption, and high stability of the device require comprehensive consideration of multiple dimensions, including hardware design, software optimization, and user experience.

[0038] Based on this, the present invention provides a wireless module device that supports two-way video intercom. Through a highly integrated circuit design, the device compactly arranges various functional modules on the circuit board, which not only achieves comprehensive functionality but also ensures the portability and ease of use of the device.

[0039] To facilitate understanding of this embodiment, a wireless module device supporting two-way video intercom disclosed in this utility model embodiment will first be described in detail.

[0040] Example 1

[0041] This utility model embodiment provides a wireless module device that supports two-way video intercom. Figure 1 This is a schematic diagram of a wireless module device supporting two-way video intercom, provided as an embodiment of the present invention. Figure 1 As shown, the wireless module device supporting two-way video intercom may include the following structure: main control chip, screen socket, power module, network distribution module, voice module and image sensor.

[0042] The main control chip, screen socket, power module, network distribution module, voice module and image sensor are integrated on the circuit board. The main control chip, screen socket, power module and network distribution module are integrated on the front of the circuit board, and the image sensor is integrated on the back of the circuit board.

[0043] The main control chip establishes a communication connection with the terminal device through the network distribution module, sending the first image information collected by the image sensor and the first sound information collected by the voice module to the terminal device, and receiving the second image information and second sound information fed back by the terminal device; the terminal device can be a mobile phone, tablet, computer, or other devices. A camera and microphone are installed on the terminal device to collect the second image information and second sound information. The network distribution module may include a Bluetooth module and a Wi-Fi module.

[0044] The screen socket is used to connect to the display and transmit the second image information sent by the main control chip to the display to display the second image information; the display can be an SPI (Serial Peripheral Interface) screen.

[0045] The power module is used to connect to an external power source to provide power to the main control chip, distribution network module, voice module, and image sensor; the external power source can provide 5V voltage.

[0046] The voice module is used to collect first sound information and play second sound information.

[0047] It is understood that the working principle of the wireless module device supporting two-way video intercom provided in this embodiment of the present invention is as follows:

[0048] The power module connects to an external power supply, providing a 5V operating voltage for the wireless module. The main control chip can control the image sensor to acquire first image information in real time and control the voice module to acquire first sound information. The first image information and the first sound information together form the video information collected by the wireless module device.

[0049] The main control chip establishes a communication connection with the terminal device through the Bluetooth or Wi-Fi module in the network configuration module. A corresponding app runs on the terminal device. Users can log in to the app to enable video intercom functionality. After logging in, users can view the video information collected by the wireless module on the app interface and activate the camera and microphone on the terminal device, allowing the terminal device to collect the user's video information. The terminal device then feeds the collected video information back to the main control chip through the network configuration module. The main control chip displays the secondary image information included in the user's video information on a monitor connected to a screen socket, and plays the secondary audio information included in the user's video information through the audio module.

[0050] In this configuration, when the main control chip establishes a connection with the terminal device, it can do so via a Wi-Fi module and a router. The main control chip then uploads the video information collected by the wireless module to a cloud platform via the Wi-Fi module and the router. The app on the terminal device then retrieves and plays the video information collected by the wireless module from the cloud platform. Similarly, the app on the terminal device uploads the user's video information to the cloud platform, and the main control chip retrieves and plays the user's video information from the cloud platform via the Wi-Fi module and the router.

[0051] This utility model provides a wireless module device supporting two-way video intercom. The device includes a circuit board on which integrates a main control chip, a screen socket, a power module, a network distribution module, a voice module, and an image sensor. The main control chip, screen socket, power module, and network distribution module are integrated on the front of the circuit board, while the image sensor is integrated on the back. Through highly integrated circuit design, a display is connected via the screen socket, and an external power supply is connected via the power module, eliminating the need to integrate a display and battery on the module, significantly reducing the size of the wireless module. By adopting a modular design, each functional module can be designed and manufactured separately, and then connected and integrated through standardized interfaces. This design method not only improves the scalability and maintainability of the device but also helps to reduce its size and weight. Compared with traditional wired video intercom systems, this wireless module device eliminates the need for complex wiring and can be flexibly deployed in any location requiring monitoring and communication, without being restricted by wiring. It achieves both comprehensive functionality and ensures portability and ease of use.

[0052] Example 2

[0053] This utility model embodiment also provides another wireless module device that supports two-way video intercom; the wireless module device that supports two-way video intercom is implemented based on the above embodiment.

[0054] Figure 2A schematic diagram of another wireless module device supporting two-way video intercom provided as an embodiment of this utility model. (See diagram below.) Figure 2 As shown, the wireless module device supporting two-way video intercom includes the following structure:

[0055] Main control chip, screen socket, power supply module, network distribution module, voice module, image sensor, motor interface, battery power detection interface, filter socket, lamp board interface, temperature sensor interface, and memory card module.

[0056] The motor interface is used to connect the lens motor, and it is integrated on the front of the circuit board.

[0057] The main control chip is also used to establish a communication connection with the terminal device through the distribution network module, receive motor control commands sent by the terminal device, and send the motor control commands to the lens motor to control the rotation of the lens motor.

[0058] The motor interface includes a vertical motor interface and a horizontal motor interface; the vertical motor interface is used to connect a vertical motor to control the lens motor to rotate in the vertical direction, and the horizontal motor interface is used to connect a horizontal motor to control the lens motor to rotate in the horizontal direction.

[0059] The motor control commands are used to control the rotation of the lens motor. The app interface running on the terminal device can include a motor control interface, where users can generate motor control commands by clicking the direction buttons. Specifically, the direction buttons include an up button, a down button, a left button, and a right button. The up and down buttons control the lens motor to rotate up or down, that is, rotate vertically. The left and right buttons control the lens motor to rotate left or right, that is, rotate horizontally.

[0060] For example, when a user clicks the "Up" button in the motor control interface, a motor control command is generated. The terminal device sends the motor control command to the main control chip via the network module. After receiving the motor control command, the main control chip sends it to the lens motor via the vertical motor interface, controlling the lens motor to rotate upwards. Similarly, when a user clicks the "Left" button in the motor control interface, a motor control command is generated. The terminal device sends the motor control command to the main control chip via the network module. After receiving the motor control command, the main control chip sends it to the lens motor via the horizontal motor interface, controlling the lens motor to rotate to the left.

[0061] By setting the motor interface, the installation position of the lens can be freely set according to the needs of the scene. By setting the motor interface to a vertical motor interface and a horizontal motor interface, all-round control of the lens motor can be achieved, which greatly expands the monitoring range of the device. Users can adjust the lens angle as needed to capture a wider and more detailed scene information, which not only improves the monitoring effect, but also enhances the user experience and satisfaction.

[0062] The voice module includes a microphone and a speaker; the microphone is integrated on the back of the circuit board, and the speaker is integrated on the front of the circuit board. The microphone is used to capture first sound information, and the speaker is used to play second sound information.

[0063] The battery power detection interface is used to connect the battery and detect the remaining battery power; the power detection interface is integrated on the back of the circuit board.

[0064] The main control chip is also used to obtain the remaining power and send the remaining power to the display and terminal devices respectively, so that the remaining power can be displayed on the display and terminal devices.

[0065] By setting up a battery power interface, the device can be powered by an external battery when the power module cannot provide power, enriching the device's power supply options, improving its adaptability to different environments, and ensuring normal operation. Simultaneously, the battery power detection interface provides real-time information on the remaining battery level, allowing users to monitor the device's battery life at both the device and terminal devices. This helps prevent issues such as sudden device shutdown or data loss due to low battery. By obtaining battery information in advance, users can take timely measures, such as backing up data or finding a charging source, ensuring stable device operation and data security. This not only enhances user experience and convenience, but also strengthens device security and reliability, and optimizes device usage efficiency and maintenance management.

[0066] The filter holder is used to connect the infrared light filter switcher, and the lamp board interface is used to connect the dual-beam lamp board. The filter holder and the lamp board interface are integrated on the back of the circuit board. The dual-beam lamp board includes infrared lamps and white lamps.

[0067] Connecting to an infrared filter switcher via a filter holder allows the device to automatically or manually switch filters based on ambient light conditions. In low-light environments, the infrared filter enhances infrared light transmittance, enabling the device to capture clear images even at night or in low-light conditions. A dual-light board connected via a light board interface provides optimal illumination under various lighting conditions. The infrared light provides sufficient infrared illumination at night or in low-light conditions to ensure image clarity, while the white light provides natural and bright illumination in well-lit environments, enhancing color reproduction and detail.

[0068] The addition of filter holders and lamp board interfaces to the equipment not only enhances its environmental adaptability and improves monitoring performance, but also increases its functionality and flexibility, allowing for easy connection to different types of filters and lamp boards to meet the needs of various application scenarios.

[0069] The temperature sensor interface is used to connect the temperature sensor, which is integrated on the back of the circuit board. The main control chip is also used to acquire the temperature data collected by the temperature sensor and send the temperature data to the display through the screen socket to display the temperature data.

[0070] By setting up a temperature sensor interface, the installation position of the temperature sensor can be freely set according to actual needs, which improves the accuracy of the temperature sensor in detecting ambient temperature and avoids the influence of heat emitted during equipment operation on the temperature sensor detection results.

[0071] The device also includes a memory card module for storing the first image information and the first sound information; the memory card module is integrated on the front of the circuit board;

[0072] The main control chip is also used to control the terminal device to play the first image information and the first sound information at a preset speed, and to control the terminal device to display a magnified or reduced image of the first image information.

[0073] A TF card can be inserted into the memory card module to store the first image and first sound information. It supports local recording and zoom playback, saving the monitoring screen at any time for easy viewing. At the same time, the screen can be zoomed in and out, allowing for more precise control over details and the overall picture.

[0074] Specifically, the app interface on the terminal device can have a playback speed adjustment button. Users can control the playback speed of the first image and first sound information on the terminal device by clicking the playback speed adjustment button. The playback speed adjustment button can include 1.5x, 2x, 2.5x, 3x, and 0.5x, that is, the preset speeds include 1.5x, 2x, 2.5x, 3x, and 0.5x.

[0075] On the APP interface of the terminal device, there can also be zoom-in and zoom-out buttons. Users can zoom in on the first image information by clicking the zoom-in button, which controls the terminal device to display a magnified image of the first image information. Users can zoom out on the first image information by clicking the zoom-out button, which controls the terminal device to display a magnified image of the first image information.

[0076] The device also includes a reset module, which controls the device to return to its initial state. The reset module is integrated on the front of the circuit board. The reset module includes a mechanical button, which the user can press to restore the device to its initial state.

[0077] This utility model provides a wireless module device that supports two-way video intercom. The device includes a circuit board. By adopting a modular design on the circuit board, each functional module can be designed and manufactured separately, and then connected and integrated through a standardized interface. While ensuring the full range of functions, it also improves the scalability and maintainability of the device, and helps to reduce the size and weight of the device.
