[0020] Before providing a further detailed description of the embodiments disclosed herein, the nouns and terms used in the embodiments of this disclosure are explained, and the nouns and terms used in the embodiments of this disclosure are subject to the following interpretations: An IoT hub (Internet of Things Hub Extension) is a device with multiple ports used to connect multiple devices to a central node. It is typically an industrial Ethernet module to meet the communication and data transmission needs between IoT devices.

[0021] The Internet of Things Station App is an application installed on a mobile device that handles the logical operations of an IoT base station.

[0022] Existing IoT base stations, serving as central devices in smart homes, connect to various sensor sub-devices to transmit and collect information, and process this information before feeding it back to servers and terminal apps. As the types of sensor sub-devices are constantly evolving, the functionality of the base stations also needs continuous upgrades. IoT base stations are constrained by the cost of hardware processors, memory, and systems, limiting the complexity of their business logic and firmware package size. This also increases the difficulty of using and learning the development environment.

[0023] To address the aforementioned issues, this application provides an IoT-based smart home communication system, method, and related apparatus. By separating the logical service portion and the communication portion of the IoT base station, with the terminal application running as the logical service portion and the communication portion consisting of independent hardware devices, the system achieves decoupling by increasing the complexity and personalization of the logical services while reducing the hardware production and maintenance costs of the communication portion.

[0024] Please refer to details. Figure 1 , Figure 1 This is a schematic diagram of the architecture of a smart home communication system based on the Internet of Things provided in an embodiment of this application, such as... Figure 1The smart home communication system 100 shown includes: an IoT hub 110, an IoT server 120, an IoT sensor sub-device 130, a first terminal device 140, and a second terminal device 150. The IoT hub 110 receives sensing messages sent by the IoT sensor sub-device 130 and forwards these messages to the first terminal device 140, the sensing messages carrying sensing data. It also receives custom messages from the first terminal device 140 and forwards them to the IoT sensor sub-device 130, the custom messages carrying custom data. The first terminal device 140 has an IoT base station application installed, used to extract sensing data based on the sensing messages, perform logical processing on the sensing data, and send the sensing data to the IoT server 120. 0; and, for receiving custom data forwarded by IoT server 120, encapsulating the custom data into a custom message, the message format of which can be recognized by IoT hub 110; IoT server 120, for analyzing sensing data, and feeding back the analysis results of the sensing data to second terminal device 150; second terminal device 150, for displaying the analysis results of sensing data to the user, and receiving custom data input by the user, and submitting the custom data to IoT server 120; IoT sensor sub-device 130, for collecting sensing data, including: environmental parameters, user behavior data, and device status data; and, in response to custom data, adjusting the operating parameters of IoT sensor sub-device 130 to the custom data.

[0025] The IoT hub 110 is connected to the IoT sensor sub-device 130 via a wireless radio frequency module in the IoT hub 110. The IoT hub 110 is connected to the first terminal device 140 via a USB OTG cable (USB On-The-Go). The IoT server 120 is connected to the first terminal device 140 via wireless communication such as WiFi and cellular network.

[0026] Specifically, the data from the IoT sensor sub-device 130 can be one or more, with different types, parameters, and configurations, each acquiring different sensing data from the environment, such as humidity, smoke concentration, and ambient light intensity. For example, when the IoT sensor sub-device 130 collects humidity data, the IoT hub 110 receives the humidity data and determines that it exceeds the standard humidity, indicating a potential health hazard to users in the current environment. The data is then encapsulated in a format recognizable by the IoT base station application and forwarded to the first terminal device 140. The IoT base station application performs logical processing based on the sensor type, parameters, and configuration of the IoT sensor sub-device 130, such as displaying it on the screen or issuing an alarm, and simultaneously sends it to the IoT server 120 for further analysis and processing. The IoT server 120 then sends the processed humidity data to the second terminal device 150, which in this example could be a dehumidifier. The second terminal device 150 can issue a prompt to the user to turn on the dehumidification function or automatically activate the dehumidification function. Furthermore, the second terminal device 150 can also be a mobile smart terminal such as a mobile phone, computer, or smartwatch.

[0027] In one possible example, the IoT hub 110 also includes: a USB OTG interface, a microcontroller, and a wireless radio frequency module; the IoT hub 110 is communicatively connected to at least one IoT sensor sub-device 130 via the wireless radio frequency module; the IoT hub 110 is connected to a first terminal device 140 via the USB OTG interface; the microcontroller is used to read sensing messages from the wireless radio frequency module and encapsulate the payload data carried by the sensing messages into a message format that can be recognized by the IoT base station application.

[0028] Please refer to Figure 2 , Figure 2 This is a functional unit diagram of an IoT hub provided in an embodiment of this application, such as... Figure 2The IoT hub 110 shown includes a USB OTG interface 210, a microcontroller unit (MCU) 220, and a radio frequency (RF) module 230. Specifically, the microcontroller unit 220 and the RF module 230 are connected via the I2C serial communication protocol, and the microcontroller unit 220 is connected to the USB OTG interface 210 via a USB wired connection. The I2C protocol bus consists of two lines: a clock line (SCL) and a data line (SDA). Structure: I2C is a master-slave communication protocol, where one device acts as the master, responsible for initiating communication and controlling the timing of communication, while other devices act as slaves, responsible for responding to the master's commands. I2C data transmission rates have multiple modes, including standard mode (100Kb / s), fast mode (400Kb / s), high-speed mode (3.4Mbps), and ultra-fast mode.

[0029] Specifically, Figure 2 The diagram also shows IoT sub-sensor A 240, IoT sub-sensor B 250, and IoT sub-sensor C 260. These IoT sub-sensors A 240, IoT sub-sensor B 250, and IoT sub-sensor C 260 are multiple sensors that may be included in the IoT sensor sub-device 130, used to collect different types of environmental data. Figure 2 It also includes a first terminal device 140 and an IoT base station application 270 installed on the first terminal device 140. Specifically, the first terminal device 140 can be a device such as a mobile phone. Currently, mobile phones have more advanced and stable processors, memory, and operating systems than embedded solutions, and their development tools and environments are also more powerful, making them easier for developers to choose. In other possible examples, the wireless radio frequency module 230 is used to forward FSK (Frequency Shift Keying), LoRa (Long Range, a low-power narrowband long-range communication technology based on spread spectrum), and ZigBee (low-power local area network protocol) network data to the IoT base station application 270.

[0030] As can be seen, in this example, by separating the IoT server and business logic, the IoT is divided into a communication part and a business processing part. For the communication part, a low-end processor is used to simplify the hardware design and reduce costs. For the business processing part, more complex and personalized needs are met by installing IoT base station applications on the first terminal device, which also enriches the diversity of software update methods.

[0031] In one possible example, in terms of feeding back the analysis results of the sensed data to the second terminal device, the IoT server is specifically used to: send the analysis results of the sensed data to the second terminal device according to the MQTT communication protocol.

[0032] MQTT (Message Queuing Telemetry Transport) is a lightweight publish / subscribe messaging protocol designed for communication between resource-constrained devices and remote devices in unstable network environments. It uses minimal network bandwidth to transmit information and is one of the mainstream protocols in the Internet of Things (IoT) scenario. MQTT features include: lightweight (MQTT message size is approximately tens of bytes, suitable for resource-constrained devices); reliable (MQTT supports reliable message transmission, ensuring no message loss, and through flexible Quality of Service (QoS) levels, it ensures secure message delivery on demand); scalability (MQTT supports multi-level topics, allowing devices to be organized into a tree structure for easy management); and security (MQTT supports multiple authentication and authorization mechanisms to guarantee data security).

[0033] In one possible example, the second terminal device includes an electronic display screen; in receiving custom data input by the user, the second terminal device is specifically configured to: receive an adjustment data message from the user, the adjustment data message representing an input operation in which the user inputs custom data into the second terminal device, the input operation including: key input, and / or input via touching the electronic display screen; obtain the custom data configured by the user based on the adjustment data message; and generate a custom message based on the custom data.

[0034] Specifically, please refer to Figure 3 , Figure 3 This is a schematic diagram of a scenario for inputting custom data provided in an embodiment of this application, such as... Figure 3The second terminal device 150 shown includes an electronic display screen 300, which can be a touch screen that allows users to operate the device by directly touching it with their fingers or other objects. After the data input field 301 in the electronic display screen 300 detects the user's custom data, the second terminal device 150 submits it to the IoT server 120. Next, the IoT server 120 sends the custom data to the IoT base station application 270 via the MQTT protocol. Then, the IoT base station application 270 retrieves the custom data from the MQTT callback, encapsulates it into a message format that the IoT hub 110 can recognize, and sends it to the IoT hub 110 via the USB OTG interface 210. Then, the IoT hub 110 reads the message from the USB OTG interface 210 cache, re-encapsulates it into an RF module message, and sends it to the IoT sensor sub-device 130. Finally, the IoT sensor sub-device 130 receives the message and responds and adjusts its own functional parameters accordingly.

[0035] Custom data can be dynamic, user-defined data such as turning lights on / off, lighting brightness, and voice broadcast content; it can also be data selected by the user to adjust the parameters of smart home sensors, such as adjusting the light intensity threshold to control the smart bulb to automatically turn on when the ambient light is insufficient; or adjusting the active start-up temperature of the smart air conditioner, such as automatically turning on the air conditioner in cooling mode when the sensor detects an ambient temperature of 32 degrees Celsius.

[0036] As can be seen in this example, by receiving the user's adjustment data message, obtaining the user's configured custom data based on the adjustment data message, generating a custom message based on the custom data, and dynamically adjusting the configuration parameters based on the user's selection, the personalization and flexibility of smart home management can be improved, which is conducive to optimizing the user experience.

[0037] In one possible example, in terms of displaying the analysis results of the perceived data to the user, the second terminal device is specifically used to: convert the analysis results of the perceived data into a graphical form and display it on an electronic display screen using a data visualization tool, which is an application installed on the second terminal device, and the graphical form includes at least one of the following: pattern mode, list mode, and chart mode.

[0038] Specifically, this includes graphical representations (such as heatmaps on a map), list representations (such as sorted lists of data), and chart representations (such as line charts, bar charts, pie charts, etc.). The electronic display screen can be any device that supports graphical display, such as an LCD screen, LED screen, or projector; the displayed analysis results of the perceived data can be dynamically updated as needed to reflect the latest data analysis results.

[0039] As can be seen in this example, by using data visualization tools, the analysis results of the perceived data are transformed into a graphical representation and displayed on an electronic screen, which optimizes the convenience for users to view environmental perception data and presents the analysis results in a more intuitive and concise manner.

[0040] In one possible example, the IoT server is also specifically used to: receive custom data sent by a second terminal device; and store the custom data as a device log for the IoT server.

[0041] Specifically, the process includes the following steps: After receiving custom data, the IoT server parses the custom data to extract the decoded data format, verify data integrity, and identify key fields; the parsed custom data is stored on the IoT server; and management operations are performed on the parsed custom data, including data backup, data recovery, data cleanup, and data security.

[0042] Decoding data formats includes JSON parsing, verifying data integrity includes checking signatures or checksums, and extracting key fields such as device ID and data values. The storage method can be a database (such as a relational database, NoSQL database, or time series database), a file system, or a cloud storage service. Finally, the stored data can be used for subsequent queries and analysis, and analysis tools can be used to extract useful information from the log data, such as device fault warnings and performance trend analysis.

[0043] In this process, user-configured custom data is stored as device logs to facilitate analysis of user-specific configurations. Subsequently, a dedicated smart home parameter archive is created for each user, providing more personalized device parameters such as light intensity and air conditioning cooling temperature when the user uses related home devices.

[0044] In one possible example, in receiving a custom message from a first terminal device and forwarding it to an IoT sensor sub-device, the IoT hub is further configured to: encode the custom message to obtain a first target message adapted to a radio frequency transmission format; modulate the first target message to obtain a second target message, the frequency of which allows it to be transmitted in a wireless channel, the modulation including at least one of the following behaviors: amplitude modulation, frequency modulation, and phase modulation; and transmit the second target message to the IoT sensor sub-device via the wireless radio frequency module of the IoT hub.

[0045] Specifically, the process of encapsulating a custom message into an RF (radio frequency) message mainly involves converting digital signals into a form suitable for transmission via radio frequency waves. This may involve the following steps: First, determining the message content: First, clarifying the content of the communication message to be transmitted, including text, images, sound, or other multimedia data; second, converting the original custom message data into a digital signal using technologies such as data compression and encryption to ensure data integrity and security; next, selecting a suitable carrier frequency, modulation method (such as amplitude modulation, frequency modulation, or phase modulation), and possible channel coding scheme to convert the digital signal into an analog signal suitable for radio frequency transmission; then, using RF encapsulation technology with specific RF encapsulation components, such as antennas, filters, and amplifiers, to encapsulate the modulated analog signal into the RF message to ensure efficient signal transmission and reception; and adhering to specific RF communication protocols and standards, such as the RF communication protocol for industrial remote control systems, to ensure correct message transmission and parsing. Furthermore, at the receiving end of the IoT sensor sub-device, using appropriate antennas and RF receiving components to receive the RF message; and performing demodulation, decoding, and decryption steps on the received RF message to reconstruct the original custom message content.

[0046] As can be seen in this example, by encoding the custom message to obtain a first target message adapted to the radio frequency transmission format, and modulating the first target message to obtain a second target message, the second target message is transmitted to the IoT sensor sub-device through the wireless radio frequency module of the IoT hub. This ensures that the signal of the custom message can be transmitted and received efficiently and accurately to the receiving IoT sensor sub-device, thereby improving the efficiency and quality of communication.

[0047] Specifically, please refer to Figure 4 , Figure 4 This is a flowchart illustrating a smart home communication method based on the Internet of Things (IoT) provided in an embodiment of this application. Figure 4 Including Figure 1 The smart home communication system 100 shown comprises the following components: IoT hub 110, IoT server 120, IoT sensor sub-device 130, first terminal device 140, and second terminal device 150, including the data uplink process: Step S410: Collect sensing data.

[0048] The sensing data collected by the IoT sensor sub-devices includes: environmental parameters, user behavior data, and device status data.

[0049] Step S420: Forward the sensing message to the first terminal device.

[0050] The IoT hub first receives sensing messages sent by IoT sensor sub-devices, which carry sensing data.

[0051] Step S430: Extract sensing data based on the sensing message, perform logical processing on the sensing data, and send the sensing data to the IoT server.

[0052] The first terminal device is equipped with an IoT base station application, which is used to process the logical business of the sensed data.

[0053] For example, an IoT server determines the analysis results based on the sensed data. In smart lighting control, for instance: ambient light data is collected via light sensors; algorithms analyze the light data to determine if the current light meets the user's needs; if the light is insufficient, a control command to adjust the brightness of the lights is generated and sent to the smart lighting device via a wireless network. Similarly, in smart temperature control: indoor temperature and humidity data are collected via temperature and humidity sensors; algorithms analyze the temperature and humidity data to determine if the current temperature and humidity meet the user's needs; if the temperature and humidity do not meet the requirements, a control command to adjust the air conditioning or heating equipment is generated and sent to the corresponding smart home device via a wireless network. In security protection, security data is collected via door and window sensors, human motion sensors, etc.; algorithms analyze the security data to determine if there are any security risks; if there are security risks, an alarm command is generated and sent to the alarm device in the smart home system or the mobile device's app via a wireless network.

[0054] Step S440: Analyze the sensing data and feed back the analysis results of the sensing data to the second terminal device.

[0055] Step S450: Show the user the analysis results of the perceived data.

[0056] Specifically, please refer to Figure 5 , Figure 5 This is a schematic diagram illustrating a scenario for displaying analysis results provided in an embodiment of this application, which is exemplary. Figure 5 The example given uses a mobile phone as the second terminal device. Figure 5 The analysis results shown indicate that the IoT server, based on sensor data, determined that the current ambient light intensity was insufficient to meet user needs. Therefore, the phone interface 500 displayed an insufficient lighting icon 510 and an information bar 520, which included multiple options. Figure 5 The system displays two options: user adjustment 521 and automatic adjustment 522. When the user selects user adjustment 521 by gesture 530, the smart home system is not adjusted through the smart home communication system. Instead, the user goes to the smart lighting device to adjust it. When the user selects automatic adjustment 522, the smart lighting device is adjusted through the above communication steps to adjust the ambient light to suit the user's needs.

[0057] In this embodiment, the existing independent IoT base station equipment is split into two parts: 1. The business logic part, which runs as an App (IoT base station application) on the mobile device; 2. The RF communication part, which is an independent peripheral hardware device that can be designed according to different protocols and frequency bands, such as supporting FSK, LoRa, ZigBee networks; 868MHz / 915MHz frequency points, etc. This hardware peripheral is connected to the mobile device via OTG and interfaces with the logical business of the business logic part to achieve decoupling.

[0058] In this embodiment, the IoT base station service can be developed by the IoT base station application team, using high-level languages ​​such as Swift, Java, and Kotlin to develop the IoT base station application. Since there are no limitations imposed by embedded hardware, this module focuses more on logical business logic, thus providing more extended functions, such as: TTS voice broadcast; emergency information / calls using mobile phone SMS and telephone; comprehensive condition judgment with AI inference, etc., enabling the development of different value-added service projects. Independent RF communication peripherals can use inexpensive components such as MCUs and RAM, reducing hardware costs and allowing for smaller size and easier installation.

[0059] This also includes the data downlink process: Step S411: Receive custom data and submit it to the IoT server.

[0060] Custom data can be dynamic, user-defined data such as turning lights on / off, light brightness, and voice announcement content.

[0061] Step S412: Receive custom data and forward it to the second terminal device.

[0062] Step S413: Encapsulate the custom data into a custom message.

[0063] Step S414: Receive the custom message and forward it to the IoT sensor sub-device.
