[0002] In recent years, with the rapid development of smart technology, building intercom technology has also penetrated into the smart home field. Indoor units are no longer just simple building intercom devices, but have gradually evolved into multifunctional terminals that integrate smart home functions. They can not only realize the function of building intercom, but also connect and control smart home devices, making users' lives more comfortable and safer.

[0003] Since the indoor unit only supports single WiFi functionality and cannot connect to multiple networks, the traditional approach is to integrate both wired and wireless network capabilities into the indoor unit. Specifically, the solution involves connecting to the park's public network via a wired network to enable video intercom functionality with the door station and management center unit; and connecting to the home LAN via a wireless network to control smart home devices.

[0004] However, using wired networks has significant drawbacks: First, wired network connections result in lower mobility and flexibility for indoor units, preventing users from easily moving their indoor units; second, wired networks require cabling and connection equipment, which can complicate the installation process and increase installation and maintenance costs. Summary of the Invention

Detailed Implementation

[0019] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0020] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0021] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this document means two or more. Moreover, the term "at least one" in this document means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0022] As described in the background section, the use of wired networks has significant drawbacks: First, wired network connections result in lower mobility and flexibility of indoor units, preventing users from easily moving the indoor units; second, wired networks require the laying of cables and connecting equipment, which can be complex to install, increasing installation and maintenance costs.

[0023] The inventors discovered through research that current building intercoms on the market only support single Wi-Fi functionality. Therefore, by integrating wired and wireless network functions into the building intercom, the wired network connects to the public network of the park to achieve video intercom functionality with the door station and management center station, while the wireless network connects to the home LAN to control smart home devices.

[0024] Based on the above research, in order to solve the above problems, this application improves the building intercom based on the Android system to realize dual WiFi function, which solves the problems of low mobility and flexibility of indoor units and complex installation process of wired network connection.

[0025] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] According to one embodiment of this application, a method for implementing dual Wi-Fi in a building intercom is proposed. The building intercom includes a first Wi-Fi module and a second Wi-Fi module, such as... Figure 1As shown, the method enables the building intercom to achieve dual Wi-Fi functionality by executing the following steps S1-S5: S1. After starting the building intercom, load the first driver file corresponding to the first Wi-Fi module and the second driver file corresponding to the second Wi-Fi module; generate a first virtual network interface card based on the first driver file; S2. Generate a second virtual network interface card based on the second driver file; S3. Configure the wireless network management service file, and set both the first virtual network interface card and the second virtual network to site mode in the wireless network management service file; S4. Create a first Wi-Fi state machine management object and a second Wi-Fi state machine management object, bind the first Wi-Fi state machine management object to the first virtual network interface card to construct the first Wi-Fi state machine, and bind the second Wi-Fi state machine management object to the second virtual network interface card to construct the second Wi-Fi state machine; S5. According to the Android system's settings application, and according to the application calling the first Wi-Fi state machine and the second Wi-Fi state machine, respectively control the first Wi-Fi module to connect to the first network and control the second Wi-Fi module to connect to the second network.

[0027] It should be noted that a state machine is a computational model used to describe the transitions and behaviors of a building intercom between different states.

[0028] As described above, the embodiments of this application integrate two independent WiFi modules into the building intercom, and create virtual network cards, configure site modes, and assign independent state machine management objects to each module at the Android system level, thereby enabling the device to connect to two different wireless networks simultaneously. This application completely replaces the traditional reliance on wired networks with a purely wireless connection, thus solving problems such as fixed indoor unit locations, high installation and maintenance costs, and poor flexibility caused by cabling. This makes device deployment more convenient and allows for greater mobility, significantly reducing the overall deployment and maintenance costs of large-scale building intercom systems.

[0029] In this embodiment, step S1 includes: adding instructions to load a first kernel object file and a second kernel object file in the initialization configuration file of the Android system kernel, wherein the first kernel object file corresponds to the first driver file and the second kernel object file corresponds to the second driver file, so that the instructions are automatically executed to load the first driver file and the second driver file when the building intercom is started.

[0030] As can be seen from the above description, the above embodiments of this application realize the automatic loading of dual WiFi drivers by pre-setting loading instructions in the system kernel initialization configuration, ensuring that the dual wireless modules can be ready immediately and reliably after the building intercom is started, thereby establishing a stable dual network connection.

[0031] In this embodiment, step S3 includes: modifying the configuration file of the wpa_supplicant service in the Android system, setting interface parameters for the first virtual network interface and the second virtual network interface in the configuration file, so that a single wpa_supplicant service process can manage the connection authentication of the two virtual network interfaces in site mode at the same time.

[0032] wpa_supplicant is an open-source WiFi connection manager used to implement WiFi network connection and security functions on Linux and other operating systems. It is responsible for implementing WiFi security protocol authentication and encrypted connection in client devices (such as mobile phones, computers, and embedded devices).

[0033] As described above, the embodiments of this application modify the configuration of the core network service of the Android system, enabling a single wpa_supplicant service process to manage two virtual network cards simultaneously. This effectively simplifies the system architecture, reduces resource overhead, and ensures the unified, efficient, and stable operation of the dual Wi-Fi connection authentication process.

[0034] In this embodiment, step S4 includes: A first client mode manager object with the role ROLE_CLIENT_PRIMARY is created as the first Wi-Fi state machine management object; a second client mode manager object with the role ROLE_CLIENT_SECONDARY_LONG_LIVED is created as the second Wi-Fi state machine management object; wherein, the second client mode manager object and the first client mode manager object run independently of each other in the Android system framework layer.

[0035] In this context, `ROLE_CLIENT_PRIMARY` is a role defined in the Android WiFi framework, representing the primary client. It is the state machine manager responsible for managing the primary, priority WiFi connection. Typically, it manages and maintains the WiFi network that the user actively connects to or that the system defaults to (such as home or office networks). It has higher system priority and is the core of the WiFi functionality. `ROLE_CLIENT_SECONDARY_LONG_LIVED` is also a role defined within the framework, representing a long-lived secondary client. It was introduced to support features like "dual WiFi" in this embodiment. This role manager runs independently of the primary client and is dedicated to establishing and maintaining a long-term, stable second WiFi connection (e.g., a channel specifically for device background data synchronization or specific application traffic). Its design goal is to supplement the primary connection without competing for control, thus achieving parallel management and coexistence of dual network connections at the system level.

[0036] As described above, the embodiments of this application achieve independent and parallel management of dual WiFi connections by creating independently running ROLE_CLIENT_PRIMARY and ROLE_CLIENT_SECONDARY_LONG_LIVED role managers. This ensures that the high priority and stability of the primary connection are not affected, while providing a dedicated, long-term channel for the second connection, effectively improving network throughput, reducing latency, and supporting differentiated service traffic scheduling.

[0037] In this embodiment, the second client mode manager object is specifically an instance of the ConcreteClientModeManager class. It independently implements the connection state switching logic of the second Wi-Fi module by binding to the second virtual network card interface, and provides an independent application programming interface to the application layer in the Android system framework layer.

[0038] As described above, the embodiments of this application implement the second client mode manager as an independent instance bound to the second virtual network card interface, thereby decoupling the control of the connection status of the second Wi-Fi module from the building intercom. This provides an independent API interface for the application layer, enabling upper-layer applications to directly and flexibly manage and use the second Wi-Fi connection, thus supporting more refined network resource scheduling and dual-channel concurrent services.

[0039] In this embodiment, step S5 includes: generating an independent graphical user interface for the second Wi-Fi module in the settings application; receiving user operations through the graphical user interface and calling the application programming interface provided by the second Wi-Fi state machine management object to realize the switching, scanning and connection control of the second Wi-Fi module.

[0040] As described above, the embodiments of this application provide an independent graphical user interface for the second Wi-Fi module in the system settings, allowing it to directly call the dedicated API of the second Wi-Fi state machine manager. This enables intuitive, convenient, and completely independent user control over the second Wi-Fi connection. This significantly improves the ease of management and user autonomy of the dual Wi-Fi function, allowing users to flexibly switch, scan, and connect to the second network as if managing the main network.

[0041] In this embodiment, the first network is the public network of the campus, which is used to realize video intercom communication with the door station or management center; the second network is the home local area network, which is used to realize the connection and control of smart home devices.

[0042] In this embodiment, the first Wi-Fi module is an SKI.WB800DS2.1 module, and the second Wi-Fi module is an SKI.W7601.1 module.

[0043] The SKI.WB800DS2.1 module, serving as the high-performance main communication module, is dedicated to accessing the campus public network (the first network). Its powerful signal processing capabilities and stability ensure low-latency, high-definition transmission of audio and video streams during video intercoms with door stations and the management center. The SKI.W7601.1 module, on the other hand, is a dedicated local connection module responsible for establishing and managing the home LAN (the second network). Its design emphasizes low power consumption, multi-device connectivity, and efficient intranet data exchange, thus reliably connecting and controlling various smart home devices. These two modules, each with its specific function, achieve physical isolation and parallel operation between critical security communication and the control of a vast number of smart home devices.

[0044] In addition, this application also proposes a building intercom system, such as Figure 2As shown, the system includes: a driver layer, comprising a first Wi-Fi module and a second Wi-Fi module; a kernel layer, used to load a first driver file corresponding to the first Wi-Fi module and a second driver file corresponding to the second Wi-Fi module after the building intercom is started; a hardware abstraction layer, used to configure a wireless network management service file, and set both the first virtual network interface and the second virtual network to site mode in the wireless network management service file; a framework layer, used to create a first Wi-Fi state machine management object and a second Wi-Fi state machine management object, bind the first Wi-Fi state machine management object to the first virtual network interface to construct the first Wi-Fi state machine, and bind the second Wi-Fi state machine management object to the second virtual network interface to construct the second Wi-Fi state machine; and an application layer, used to control the first Wi-Fi module to connect to the first network and control the second Wi-Fi module to connect to the second network according to the settings application of the Android 12 system, and according to the application calling the first Wi-Fi state machine and the second Wi-Fi state machine respectively.

[0045] In summary, such as Figure 4 As shown, the above embodiments of this application aim to introduce a second WiFi module on the basis of the single WiFi application framework of the Android system so that the building intercom can support the dual WiFi function, and meet the scenario that the building intercom can connect to the public network of the park through WiFi1 for video intercom function, while also connecting to the home LAN through WiFi2 to realize the control of smart home devices.

[0046] In this embodiment, the dual Wi-Fi logic is implemented in five layers: driver layer, kernel layer, hardware abstraction layer (HAL layer), framework layer, and application layer.

[0047] In this embodiment, the driver layer needs to select two compatible Wi-Fi modules and connect them to the main controller via a hardware communication interface, such as... Figure 3 As shown.

[0048] In this embodiment, the kernel layer ports two Wi-Fi drivers provided by the first and second Wi-Fi module vendors. Two .ko files, wifi1.ko and wifi2.ko (i.e., the first and second driver files), are generated through compilation on the Linux system. Instructions for loading wifi1.ko and wifi2.ko files (insmod wifi1.ko and insmod wifi2.ko) are added to the init.insmod.cfg file to ensure that the system can execute these instructions correctly during startup to load the drivers. After successful driver loading, the drivers are matched with the corresponding Wi-Fi modules to generate two virtual network interface cards (wlan0 and wlan1) for use by the hardware abstraction layer, such as... Figure 5 As shown.

[0049] In this embodiment, the hardware abstraction layer modifies the startup parameters of the wpa_supplicant service process and sets the parameters of the two virtual network interface cards, wlan0 and wlan1, in the wpa_config.txt configuration file, so that both the wifi1 module and the wifi2 module work in station mode.

[0050] In this embodiment, the framework layer instantiates a ConcreteClientModeManager object with the role of ROLE_CLIENT_SECONDARY_LONG_LIVED, and establishes a binding relationship with the second Wi-Fi module by binding it to the wlan1 virtual network card interface. This object mainly implements the state machine of the second Wi-Fi module, is responsible for implementing the switching logic of different connection states of the second Wi-Fi module, and provides the application layer with the on / off and connection API interface of the second Wi-Fi module, so that the first Wi-Fi module and the second Wi-Fi module are independent of each other in the framework layer.

[0051] In this embodiment, the application layer adds a graphical user interface for the second Wi-Fi module based on the existing system settings application of Android 12, and manages and controls Wi-Fi 2 by calling the API interface provided by the framework layer.

[0052] In summary, this application reduces the cost of physical cables and connection equipment required for wired network connections by employing a wireless network connection. It also avoids the manpower and time costs associated with maintaining and replacing physical connections. For large-scale network deployments, especially building intercom systems, wireless connectivity can save significant costs and resources.
