[0003] However, current IoT is usually built on a set of physical devices and sensors. Office buildings, factories, laboratories and other areas are already equipped with enough physical devices and sensors. However, the brands and models of these physical devices and sensors are not completely compatible, which makes it impossible for different brands and models of physical devices and sensors to communicate with each other. This leads to the need to replace all physical devices and sensors when building IoT in these areas, resulting in high construction costs for IoT in existing office buildings, factories, laboratories and other areas.

Detailed Implementation

[0024] This application applies to the HarmonyOS system. HarmonyOS enables rapid discovery, connection, hardware collaboration, and resource sharing of various smart terminals that consumers encounter in all aspects of daily life through intelligent interconnection, providing a suitable user experience. HarmonyOS features include intelligent interconnection, hardware collaboration, and resource sharing. The system supports seamless collaboration between various devices, such as mobile phones, watches, televisions, and speakers, achieving interconnection and interoperability. Furthermore, HarmonyOS supports one-time development and multi-device deployment. Developers, based on a distributed application framework, can write logic code once and then deploy it on multiple terminals. The following explanations of some terms used in this application are provided to facilitate understanding by those skilled in the art. It should be noted that when the solutions of this application are applied to the HarmonyOS system, existing systems, or other systems that may emerge in the future, the names of IoT controllers, sensors, and terminals may change, but this does not affect the implementation of the solutions in this application.

[0025] Figure 1 This application provides an embodiment of an IoT communication method based on the HarmonyOS system, which includes the communication connections between an IoT controller, sensors, and terminals, as well as the relationships between sensors and detection areas, terminals and control areas, and detection areas and control areas. Specifically, the IoT controller is communicatively connected to at least one sensor 11 and at least one terminal. One sensor 11 is used to detect an environmental condition within a detection area, and one terminal is used to control at least one environmental condition within a control area, encompassing at least one detection area.

[0026] Figure 2 A signaling diagram of an IoT communication method based on the HarmonyOS system provided in this application embodiment is shown below. Figure 2 As shown, the method includes: S201: The sensor receives a start command from the IoT controller.

[0027] In this example, the sensor detects the environmental conditions of the detection area according to the start command sent by the IoT controller, obtains the detection signal, and realizes the beneficial effect of the IoT controller controlling the sensor. This allows users to set the detection cycle of each sensor in the IoT controller according to their needs, ensuring that the environmental detection frequency of the sensor can be effectively controlled.

[0028] An IoT controller is a control unit used in the Internet of Things (IoT) to process and transmit signals from sensors and terminals. The Internet of Things (IoT) refers to connecting any object to a network through information sensing devices such as RFID, infrared sensors, GPS, and laser scanners, according to agreed-upon protocols, to exchange and communicate information, thereby achieving intelligent identification, positioning, tracking, and monitoring functions.

[0029] S202: The sensor generates a detection signal according to the start command and sends the detection signal to the IoT controller; the detection signal records an environmental condition of the sensor's detection area; the types of environmental conditions include: air temperature, air humidity, air velocity, toxic gas content, particulate matter index and illuminance.

[0030] In this example, the sensor is equipped with the HarmonyOS system, which generates a detection signal according to the startup command and sends the detection signal to the IoT controller. Therefore, the detection signal generated by the sensor can be directly recognized and used by the IoT controller, improving the interaction efficiency between the sensor and the IoT controller.

[0031] Specifically, at least one sensor provided in this application includes: An air temperature sensor is used to measure the temperature of air. The conversion from temperature to an electrical signal is typically achieved using thermocouples, resistance temperature detectors (RTDs) such as platinum resistance thermometers, or semiconductor temperature sensing elements. At least one detection voltage in the detection signal sent by the air temperature sensor characterizes the air temperature of the detected area during the detection period.

[0032] An air humidity sensor is used to measure the relative humidity of the air. Common types include capacitive humidity sensors and resistive humidity sensors (such as lithium chloride hygrometers and polymer humidity sensors). At least one detection voltage in the detection signal sent by the air humidity sensor characterizes the air humidity of the detection area during the detection period.

[0033] An air velocity sensor is used to measure the speed of airflow. Common types include hot-wire anemometers, pitot tube anemometers, and ultrasonic anemometers. At least one detection voltage in the detection signal sent by the air velocity sensor characterizes the air velocity in the detection area during the detection period.

[0034] Toxic gas concentration sensors are used to detect the concentration of toxic gases in the air, such as carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2), and nitrogen dioxide (NO2). These sensors may operate based on principles such as electrochemistry, semiconductors, infrared absorption, or catalytic combustion. At least one detection voltage in the detection signal sent by the toxic gas concentration sensor characterizes the concentration of toxic gases in the detection area during the detection period.

[0035] Particulate matter index sensors (commonly known as PM sensors) are used to measure the concentration of particulate matter in the air, particularly PM2.5 (particulate matter with a diameter of 2.5 micrometers or less) and PM10 (particulate matter with a diameter of 10 micrometers or less). These sensors typically operate using laser scattering or optical counting principles. At least one detection voltage in the detection signal sent by the particulate matter index sensor characterizes the particulate matter concentration in the detection area during the detection period.

[0036] Illuminance sensors are used to measure the intensity or brightness of light. Common types include photoresistors (photodiodes or phototransistors), silicon photovoltaic cells, and lux meters. At least one detection voltage in the detection signal sent by the illuminance sensor characterizes the intensity or brightness of light in the detected area during the detection period.

[0037] In a preferred embodiment, the sensor generates a detection signal according to a start command and sends the detection signal to the IoT controller, including: The sensor obtains the time span based on the current timestamp and the previous timestamp; where the current timestamp is the time when the sensor received the start command this time; the previous timestamp is the time when the sensor last received the start command. If the sensor determines that the time span exceeds a preset time threshold, it will activate the environmental conditions of the sensor's detection area to generate a detection signal and send the generated detection signal to the IoT controller. If the sensor determines that the time span has not exceeded the time threshold, it will send the detection signal that the sensor previously sent to the IoT controller back to the IoT controller.

[0038] In this example, the IoT controller may malfunction or be frequently triggered by the user, causing the sensor to receive a large number of start commands. This results in the sensor frequently collecting environmental information in the detection area, leading to a reduction in the sensor's lifespan, as well as blockage of the communication line between the IoT controller and the sensor.

[0039] In this example, the sensor obtains the time span based on the current timestamp and the previous timestamp. If the sensor determines that the time span exceeds a preset time threshold, it detects the environmental conditions in the sensor's detection area to generate a detection signal and sends the generated detection signal to the IoT controller. The descendant of the two activation signals for time spans that do not exceed the time threshold is set as an abnormal activation signal, and the detection signal previously sent by the sensor to the IoT controller is sent to the IoT controller again. The two activation signals for time spans that exceed the time threshold are set as normal activation signals, and the environmental conditions in the sensor's detection area are then activated to generate a detection signal.

[0040] Furthermore, if the sensor determines that the time span has not exceeded the time threshold, it will resend the detection signal previously sent by the sensor to the IoT controller, including: If the sensor determines that the time span has not exceeded the time threshold, it will obtain the number of times the detection signal previously sent by the sensor to the IoT controller will be sent to the IoT controller again. If the sensor determines that the number of attempts has not exceeded the limit, it will send the detection signal that the sensor previously sent to the IoT controller to the IoT controller again. If the sensor determines that the number of attempts exceeds the limit, it will activate the environmental conditions of the sensor's detection area to generate a detection signal and send the generated detection signal to the IoT controller.

[0041] In this example, if the IoT controller frequently sends start commands to the sensor, the sensor will repeatedly send the previously sent detection signal back to the IoT controller, causing the IoT controller to be unable to obtain the true environmental conditions of the monitored area, thus leading to sensor failure. To address this, by determining the number of times the previously sent detection signal is sent to the IoT controller, the sensor is allowed to start normally and collect environmental data when the number of attempts exceeds a certain limit. This ensures that even if the IoT controller malfunctions or is misoperated, the sensor will still function normally and will not fail.

[0042] S203: The IoT controller calculates the detection voltage in the detection signal based on at least one sensing function corresponding to the detection signal to obtain a corrected detection voltage; wherein, the corrected detection voltage is a voltage value formed by correcting the detection voltage at at least one acquisition point.

[0043] In this example, the detection voltage in the detection signal is a voltage signal generated by a sensor that detects environmental conditions at at least one acquisition point within a preset detection period. The detection signal from the sensor is received by the IoT controller, which manages the sensor's detection signal and avoids the sensor directly sending the signal to the terminal, which would prevent the terminal from recognizing the detection signal.

[0044] The detection voltage in the detection signal is calculated by the sensing function corresponding to the detection signal to obtain a method for verifying the detection voltage. This method eliminates erroneous or large-error detection voltages detected by the detection sensor during the detection period, thereby eliminating detection errors and obtaining a corrected detection voltage that reflects the most accurate environmental conditions of the detection area.

[0045] In a preferred embodiment, the IoT controller performs calculations on the detection voltage in the detection signal based on at least one sensing function corresponding to the detection signal to obtain a corrected detection voltage, including: The IoT controller retrieves at least one sensing function corresponding to the detected signal from a pre-set function library based on the type of environmental condition of the detected signal; wherein, the function library includes at least one sensing function; the at least one sensing function includes: mean function, median function and variance function; The IoT controller performs calculations on at least one detection voltage in the detection signal based on at least one acquired sensing function to obtain a corrected detection voltage.

[0046] In this example, the mean function is used to calculate the average of a set of data, which is the sum of all data points divided by the number of data points.

[0047] The median function is used to find the median of a set of data, which is the middle value after sorting. If the number of data points is even, the median is the average of the two middle values.

[0048] The variance function measures the dispersion of data, that is, how much the data points deviate from the mean. Variance is the average of the squared deviations.

[0049] For example, when the environmental condition of the detected signal is air temperature, the corresponding sensing functions include a mean function and a variance function. The variance function is called to calculate the voltage variance of at least one detected voltage in the detected signal. If the voltage variance does not exceed a preset variance threshold, the mean function is called to calculate the voltage mean of at least one detected voltage, and this voltage mean is set as the calibration detection voltage. If the voltage variance exceeds the preset variance threshold, a start command is sent to the sensor again.

[0050] When the environmental condition of the detected signal is air humidity, the corresponding sensing functions include: a mean function and a variance function. The variance function is used to calculate the voltage variance of at least one detected voltage in the signal. If the voltage variance does not exceed a preset variance threshold, the mean function is used to calculate the voltage mean of at least one detected voltage, and this voltage mean is set as the calibration voltage. If the voltage variance exceeds the preset variance threshold, a start command is sent to the sensor again.

[0051] When the environmental condition detected is airflow velocity, the corresponding sensing functions include a mean function and a variance function. The variance function is used to calculate the voltage variance of at least one detected voltage in the signal. If the voltage variance does not exceed a preset variance threshold, the mean function is used to calculate the average voltage of at least one detected voltage, and this average voltage is set as the calibration voltage. If the voltage variance exceeds the preset variance threshold, a start command is sent to the sensor again.

[0052] When the environmental condition detected is a toxic gas content, the corresponding sensing functions include a median function and a variance function. The variance function is used to calculate the voltage variance of at least one detected voltage in the signal. If the voltage variance does not exceed a preset variance threshold, the median function is used to calculate the median voltage of at least one detected voltage, and this median voltage is set as the calibration detection voltage. If the voltage variance exceeds the preset variance threshold, a start command is sent to the sensor again.

[0053] When the environmental condition detected is particulate matter, the corresponding sensing functions include a median function and a variance function. The variance function is used to calculate the voltage variance of at least one detected voltage in the signal. If the voltage variance does not exceed a preset variance threshold, the median function is used to calculate the median voltage of at least one detected voltage, and this median voltage is set as the calibration voltage. If the voltage variance exceeds the preset variance threshold, a start command is sent to the sensor again.

[0054] When the environmental condition for detecting the signal is illuminance, the corresponding sensing function includes: a mean function. The mean function is called to calculate the average voltage of at least one detected voltage, and this average voltage is then set as the calibration voltage.

[0063] S204: The IoT controller assigns an IP address to the calibration detection voltage based on the sensor's identity information; wherein, the IP address is used to characterize the control area where the sensor's detection area is located; the control area is the area where the terminal adjusts the environmental conditions; the control area includes at least one detection area.

[0064] In this example, the IoT controller assigns IP addresses to the calibration detection voltage based on the sensor's identity information to determine the source of the calibration detection voltage, so that the corresponding terminal can be accurately located to adjust the environmental conditions of the detection area.

[0065] In a preferred embodiment, the IoT controller assigns an IP address to the calibration detection voltage based on the sensor's identity information, including: The IoT controller obtains the area identifier of the identity information and the IP set corresponding to the area identifier; wherein, the area identifier represents the detection area of ​​the sensor; the IP set includes at least one IP address; the IP set corresponds to the control area; If the IoT controller determines that there is at least one free IP address in the IP set, it will assign one of the at least one free IP address to the correction detection voltage.

[0066] In this example, the IoT controller obtains the area identifier of the identity information and the set of IPs corresponding to the area identifier to ensure that the control area corresponding to the subsequently allocated IP address includes the detection area of ​​the sensor.

[0067] If the IoT controller determines that there is at least one free IP address in the IP set, it will allocate one of the at least one free IP address to the calibration detection voltage. This will enable control over the processing volume of subsequent calibration detection voltages and prevent the IoT controller from becoming too complex due to excessive parallel processing of calibration detection voltages, which could lead to crashes or freezes.

[0068] Specifically, the area identifier is a character or string that represents the detection area of ​​the sensor, for example: A1; A is to control area A, and 1 refers to detection area number 1 in the control area.

[0069] IP sets correspond to control regions. For example, IP set A corresponds to control region A.

[0070] The IP addresses in IP set A are used to assign detection messages to sensors in detection areas A1-A10 within control area A.

[0071] S205: The IoT controller generates a control signal based on the calibration detection voltage and IP address, and sends the control signal to the terminal; the control signal is an electrical signal used to instruct the terminal to adjust the environmental conditions of the sensor's detection area to a preset environmental standard.

[0072] In this example, the IoT controller generates a control signal based on the calibration detection voltage and IP address, and sends the control signal to the terminal corresponding to the IP address. This allows the terminal to adjust the environmental conditions of the detection area so that the environmental conditions of the detection area can meet the environmental standards. It also ensures that the terminal can recognize the control signal.

[0073] The IoT controller is equipped with the HarmonyOS system. The HarmonyOS system is used to calculate the detection voltage in the detection signal based on at least one sensing function corresponding to the detection signal, thereby obtaining a corrected detection voltage. The HarmonyOS system is also used to assign an IP address to the corrected detection voltage based on the sensor's identity information. Furthermore, the HarmonyOS system is used to generate a control signal based on the corrected detection voltage and the IP address, and send the control signal to the terminal. By installing the HarmonyOS system in the IoT controller, the IoT controller can directly identify the detection signal sent by the sensor without decoding, enabling seamless interaction and communication between each device in the Internet of Things.

[0074] In a preferred embodiment, the IoT controller generates a control signal based on the calibration detection voltage and the IP address, including: The IoT controller acquires the environmental standard corresponding to the detection area of ​​the detection signal, and generates analysis information based on the calibration detection voltage and the environmental standard. The environmental standard defines the numerical range of each environmental condition for each detection area within the control area. The analysis information is used to characterize the numerical relationship between the environmental condition and the environmental standard for the calibration detection voltage. If the IoT controller determines that the analyzed information exceeds the stability standard corresponding to the environmental standard, it generates control information. The control information is data used to instruct the terminal to adjust the environmental conditions of the sensor's detection area to the preset environmental standard. The stability standard defines the numerical threshold values ​​in each detection area within the control area that can trigger the terminal to adjust the environmental conditions within the control area. The IoT controller obtains the rule set corresponding to the IP set, determines the terminal based on the type of environmental condition recorded in the detection signal, and sets the encoding rule of the determined terminal as the target encoding rule; The IoT controller encodes control information, IP address, and area identifier according to the target encoding rules to obtain control signals.

[0075] In this example, the IoT controller obtains the environmental standard corresponding to the detection area of ​​the detection signal, and determines whether the environmental condition of the current detection area deviates from the user's predetermined environmental standard by generating analysis information based on the corrected detection voltage and environmental standard.

[0076] If the IoT controller determines that the analyzed information exceeds the corresponding stability standard of the environment, it will generate control information to activate the terminal only when the environmental conditions exceed the stability standard, thus avoiding the terminal being frequently started and stopped, which would cause energy waste.

[0077] Since there are many different types, models, and brands of terminals, each type, brand, and model of terminal may follow different encoding rules. Therefore, the IoT controller obtains the rule set corresponding to the IP set and determines the target encoding rule based on the detection signal to obtain the encoding rule of the terminal corresponding to the control area where the detection area is located, ensuring that the generated control signal can be recognized and used by the terminal.

[0078] For example, the rule set corresponding to the IP set has at least one terminal for controlling the environmental conditions of the control area A, such as: air conditioning equipment A, fresh air system A, air filtration system A, automatic curtain A; If the environmental conditions recorded in the detection signal are air temperature and air humidity, then the identified terminal is air conditioning device A. Therefore, the coding rule for air conditioning device A is set as the target coding rule. If the environmental conditions recorded in the detection signal are air velocity and toxic gas content, then the identified terminal is fresh air system A. Therefore, the coding rule for fresh air system A is set as the target coding rule. If the environmental condition recorded in the detection signal is a particulate matter index, then the identified terminal is air filtration system A. Therefore, the coding rule for air filtration system A is set as the target coding rule.

[0079] If the type of environmental condition recorded in the detection signal is illuminance, then the identified terminal is automatic curtain A. Therefore, the encoding rule for automatic curtain A is set as the target encoding rule.

[0080] Specifically, environmental standards are numerical ranges defined by users for each environmental condition in each detection area of ​​each control area, according to their needs; for example: A1-temperature-[16℃-20℃], which represents the temperature of detection area 1 in control area A, controlled between 16℃ and 20℃.

[0081] The numerical relationships represented by the analysis information include: included in, greater than, and less than; among them, included in represents the environmental conditions of the correction detection voltage being within the corresponding environmental standard numerical range. For example, if the air temperature represented by the correction detection voltage is 18℃, then it will be included in A1-temperature-[16℃-20℃].

[0082] The environmental conditions that exceed the calibration test voltage are greater than the upper limit of the corresponding environmental standard's numerical range. For example, if the air temperature represented by the calibration test voltage is 23℃, then it will be 3℃ higher than the A1-temperature-[16℃-20℃] higher standard.

[0083] The environmental condition characterized by the calibration test voltage is less than the lower limit of the corresponding environmental standard value range. For example, if the air temperature characterized by the calibration test voltage is 13℃, then it will be 3℃ lower than the environmental standard A1-temperature-[16℃-20℃].

[0084] The stability standard defines the threshold values ​​for each environmental condition within the control area that trigger the terminal to adjust the control area's environmental conditions. For example, based on the above example, the stability standard includes: A1 - Temperature - Upper limit threshold 2℃ and Lower limit threshold 5℃. If the air temperature represented by the calibration detection voltage is 23℃, then it is greater than the upper limit of A1 - Temperature [16℃-20℃] by 3℃. Since it is greater than the upper limit threshold, the terminal will be activated to control the temperature. If the air temperature represented by the calibration detection voltage is 13℃, then it is less than the lower limit of A1 - Temperature [16℃-20℃] by 3℃. Since it is less than the lower limit threshold, the terminal will not be activated. Similarly, there are calibration detection voltages, environmental standards, and stability standards for air temperature, air humidity, air velocity, toxic gas content, particulate matter, and illuminance.

[0085] Control information is an electrical signal used to instruct the terminal to adjust the environmental conditions of the sensor's detection area to a preset environmental standard. Therefore, the terminal can use at least one output rule to adjust the environmental conditions of each detection area within the control area. The output rule includes at least one out-of-limit indicator and output parameters corresponding to each out-of-limit indicator. The out-of-limit indicator represents the degree to which the environmental conditions of the correction detection voltage exceed the environmental standard. The output parameter refers to the parameter configuration used by the terminal to adjust the environmental conditions of the detection area within the control area to the environmental standard. For example, if the out-of-limit indicator exceeds the upper limit threshold of the stable standard by 1°C (e.g., 23°C), its output parameter is 2°C lower than the upper limit of the environmental standard (e.g., the output temperature of an air conditioner is 18°C); if the out-of-limit indicator exceeds the upper limit threshold of the stable standard by 2°C (e.g., 24°C), its output parameter is 3°C lower than the upper limit of the environmental standard (e.g., the output temperature of an air conditioner is 17°C).

[0086] Encoding rules are computer rules that encode information into different voltage levels or voltage variation patterns to transmit data via electrical signals. In this embodiment, the encoding rules include: NRZ (Non-Return-to-Zero) coding rule: Logic 0 and logic 1 are represented by two different voltage levels, which remain constant throughout the bit cycle. It is simple to implement, but prolonged high or low levels can lead to synchronization problems.

[0087] NRZ-I (Invert) rule: Logic 0 maintains the current voltage level, while logic 1 performs a level transition (high to low or low to high). Level changes provide clock synchronization information, reducing synchronization problems.

[0088] Return-to-Zero (RZ) encoding rule: The voltage signal of each bit returns to zero level within the bit cycle. Logic 0: low level to zero level. Logic 1: high level to zero level. Better clock synchronization, but requires higher bandwidth.

[0089] Manchester encoding rules: There is a level transition in the middle of each bit cycle. Logic 0: High to low transition. Logic 1: Low to high transition. It is self-synchronizing and has strong anti-interference capabilities, but has higher bandwidth requirements.

[0090] Differential Manchester encoding rules: There is a level transition at the center of each bit cycle. Logic 0: No transition at the beginning of the bit. Logic 1: Transition at the beginning of the bit. Similar to Manchester encoding, but more resistant to interference.

[0091] 4B / 5B encoding rule: Encode 4 bits of data into 5 bits of code to ensure at least one level change. This ensures sufficient level transitions for clock synchronization and is commonly used in Fast Ethernet.

[0092] PAM (Pulse Amplitude Modulation) rules: Different voltage levels represent different data values. For example, PAM-4 represents four voltage levels, each representing two bits. This increases the data rate but is more sensitive to signal noise and distortion.

[0093] MLT-3 (Multi-Level Transmit-3) encoding rules: Encoding is performed using three voltage levels (positive, neutral, and negative). The order of level changes is: 0 → + → 0 → - → 0. This reduces bandwidth requirements and is suitable for high-speed Ethernet (100BASE-TX).

[0094] Bi-phase code rules: Includes Manchester encoding and differential Manchester encoding, ensuring one level change in each bit. Self-synchronizing, suitable for high-speed communication.

[0095] Symbol Interval Coding rule: An interval (zero level) is inserted between symbols to provide clock information. Suitable for T1 / E1 line encoding, such as B8ZS and HDB3. It solves the problem of no voltage level change for extended periods and is suitable for long-distance transmission.

[0096] Symbol mapping rules map data to specific voltage symbols, such as QAM (Quadrature Amplitude Modulation). QAM uses a combination of phase and amplitude to represent data. It efficiently utilizes bandwidth and is suitable for modern high-speed communication systems.

[0097] The control signal includes: control information, IP address, and area identifier; the control information records the over-limit indicators and output parameters; the IP address is used to identify the receiving terminal of the control signal; the area identifier is used to inform the terminal of the detection area for adjusting environmental conditions.

[0098] The control information is also used to instruct the terminal to adjust the environmental conditions of the detection area corresponding to the area identifier according to the output parameters; for example, the control information instructs the air conditioning equipment in control area A to adjust the output direction to detection area A1 and output cold air at a temperature of 18°C ​​to detection area A1.

[0099] S206: The terminal receives control signals from the IoT controller and adjusts the environmental conditions of the sensor's detection area to the preset environmental standards according to the control signals.

[0100] In this example, the terminal adjusts parameters and starts operation based on control signals sent by the IoT controller to adjust the environmental conditions of the sensor's detection area to the environmental standard, achieving dynamic adjustment of the environmental conditions. The terminal is equipped with the HarmonyOS system, which receives control signals from the IoT controller and adjusts the environmental conditions of the sensor's detection area to the preset environmental standard based on these signals. Therefore, by installing HarmonyOS in the terminal, the terminal can directly acquire and recognize the control signals sent by the IoT controller, thereby improving the efficiency of information interaction between the IoT controller and the terminal.
