[0016] Figure 1 The utility model is a functional block diagram of a video intercom system according to an embodiment of the utility model. DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below. Figure 1 The embodiment of the utility model provides a video intercom system, including an indoor unit, a door station, a main controller, a plurality of defense zone sensors and a wireless hub. The main controller is used to control the operation of the entire system and the execution of complex functions such as face recognition. It is electrically connected to the indoor unit, the main wireless communication unit, the Ethernet unit and the main power management unit, and can be connected to the Internet through the Ethernet unit so that the user can remotely control the system through the APP on the smart terminal. The main power management unit is used to power the system and can provide standard voltages of various specifications such as 3.3V, 1.5V and 0.9V. The door station is used to be set at the gate of the courtyard, and the indoor unit is set inside the house. The indoor unit can communicate with the door station through the main controller to realize video calls between the door station and the indoor unit. The defense zone sensor is set in the courtyard and electrically connected to the wireless hub. The door station and the wireless hub respectively include a first wireless communication unit and a second wireless communication unit. The door station and the wireless hub can respectively communicate wirelessly through their respective wireless communication units and the main wireless communication unit connected to the main controller to realize information transmission. The detection signals of each zone sensor can be transmitted to the wireless hub first, and then wirelessly transmitted to the video intercom system by the wireless hub, so as to realize the linkage between the video intercom system and the zone sensor system. And because both the door phone and the wireless hub can communicate wirelessly with the main controller installed in the house, there is no need to wire the door phone, zone sensor and main controller, which reduces the number of cables, facilitates installation, and avoids the difficulty of subsequent maintenance caused by messy wire harnesses.

[0018] In this embodiment, there are multiple indoor units, including a visual indoor unit installed in the living room of the residence and a non-visual indoor unit installed in other rooms. Both the visual indoor unit and the non-visual indoor unit include an indoor unit controller, and an indoor microphone and an indoor speaker electrically connected to the indoor unit controller. Figure 1 The visual indoor unit also includes a touch screen, an indoor display screen and an indoor camera electrically connected to the indoor unit controller. The indoor unit controller is electrically connected to the main controller. In order to further reduce the number of cables, RVV4 cables are used for the electrical connection between the indoor unit and the main controller, and between each indoor unit. In this embodiment, in order to improve the user experience, the indoor display screen uses an IPS MIPITFT display screen with a resolution of 1024*600, and the touch screen uses a G+G multi-finger touch screen.

[0019] The door station includes an access control controller and an access control power supply electrically connected to the access control controller, a door camera, a door speaker, a door microphone, a doorbell button and a door display screen, and the access control controller is electrically connected to the first wireless communication unit. When the visitor presses the doorbell button, the door camera, the door video camera, the door microphone and the door display screen all start working to realize a video call with the indoor station.

[0020] Reference Figure 1 In this embodiment, the wireless hub also includes a hub controller, a hub power supply, a terminal block, a USB interface circuit and an RJ45 interface circuit. The terminal block, the USB interface circuit and the RJ45 interface circuit are all electrically connected to the hub controller, and the hub controller is electrically connected to the second wireless communication unit and the hub power supply. The wireless hub can be adapted to defense zone sensors with a variety of different interfaces through the terminal block, the USB interface and the RJ45 interface, thereby improving the compatibility of the system with the defense zone sensors. It is understandable that the defense zone sensor can adopt an infrared sensor or a vibration fiber optic sensor, etc., and two wireless hubs can be set up to cooperate with two groups of defense zone sensors to realize a dual defense zone layout, thereby further improving the safety of the residential courtyard. In this embodiment, in order to prevent the electrical signal output by the defense zone sensor from interfering with the hub controller, the terminal block is electrically connected to the hub controller through an optical coupler.

[0021] In some embodiments, the video intercom system also includes an internal memory and an external memory read-write unit, both of which are electrically connected to the main controller. The internal memory is used to store information such as videos and photos taken by the camera and trigger records of the defense zone sensor. The external memory read-write unit is used to insert external storage devices such as USB flash drives, mobile hard drives or TF cards. By storing audio or picture files in the TF card, the ringtone and display background can be customized, thereby increasing the entertainment value of the video intercom system.

[0022] It can be understood that the first wireless communication unit, the second wireless communication unit and the main wireless communication unit should adopt Bluetooth units and WI FI units, and the WI FI unit should adopt a WI FI unit that supports WI FI 6, which can form 2.4GHz and 5GHz wireless LANs with strong compatibility and high stability.

[0023] The main controller should adopt a visual SoC chip with strong graphics processing capabilities, which can complete face recognition faster. In this embodiment, the main controller adopts the SV810 chip produced by Zhuhai Yizhi Electronic Technology Co., Ltd., which integrates dual-core CPU, NPU, L1+L2 cache, dynamic voltage and frequency adjustment, video codec (H.265) and ISP. It has AI human detection and tracking functions, which can effectively improve detection accuracy and reduce misjudgment caused by object movement. The system runs smoothly, has low power consumption and good image effect.

[0024] In this embodiment, the video intercom system also includes an access control electronic lock, a fingerprint electronic lock and an electric control electronic lock. The access control electronic lock is set on the courtyard gate, is electrically connected to the door, and is controlled by the door machine. The fingerprint electronic lock and the electric control electronic lock are installed on the main door of the house. The fingerprint electronic lock is connected to the main controller and can only be unlocked by the fingerprint contact. The electric control electronic lock is electrically connected to the indoor machine and is directly controlled by the indoor machine. When the user is away from home for a long time, the fingerprint electronic lock is used to lock the main door of the house to prevent remote control from opening the door, further improving the safety of the house; when the user is at home or away from home for a short time, the electric control electronic lock is used to lock the main door of the house for easy unlocking. The fingerprint electronic lock should be powered by an external power supply to avoid the inability to unlock the door when the system is powered off.
