Description

Technical Field

[0001] This invention relates to the field of intelligent air conditioning control technology, and in particular to a multifunctional air conditioning parameter control system, method, and smart socket based on dual-mode communication. Background Technology

[0002] In the early days, air conditioner parameter control mainly relied on traditional infrared remote controls. These remote controls had limited communication range and were significantly affected by obstacles, allowing only basic parameter adjustments for a single local device. They could not meet users' needs for remote monitoring or collaborative management of multiple devices. Furthermore, the compatibility between the remote control and the air conditioner was highly dependent on a pre-set infrared protocol; different brands and models of air conditioners required dedicated remote controls, resulting in extremely poor compatibility.

[0003] With the popularization of IoT technology and smart home concepts, some solutions have attempted to introduce dual-mode communication and intelligent algorithms. However, when exploring air conditioner control technology, it was found that: although dual-mode controllers using 4G and Bluetooth support both near and long-range control, Bluetooth's coverage range is only less than 10 meters, making it difficult to effectively control large home appliances like infrared; infrared protocol matching solutions based on cloud-based code libraries require the pre-storage of massive protocol libraries, which not only consumes too much storage resources but also makes it difficult to adapt to the ever-emerging new air conditioner models; although the introduced PID algorithm is used to optimize air conditioner temperature control, it does not take into account power consumption data, and is prone to system oscillations during sudden temperature changes, affecting the control effect.

[0004] Currently, there are still many technical bottlenecks in the market for intelligent air conditioning control systems. Existing dual-mode systems are based solely on simple threshold switching and do not consider signal stability (such as duration), resulting in frequent mode jitter. Air conditioning protocol matching relies on a preset code library, requiring manual intervention for new devices or non-standard protocols, and cannot automatically lock the protocol through power or temperature feedback. Energy-saving algorithms do not use temperature change rate as a dynamic weighting factor, leading to a sharp drop in energy efficiency in high-fluctuation scenarios. At the same time, smart sockets only support basic on / off switching, lacking triple protection against overcurrent, leakage, and overtemperature, as well as the ability to adapt to non-standard plugs, failing to meet the safety control requirements of high-power air conditioning scenarios.

[0005] Chinese invention patent CN106322656B discloses an air conditioning control method, server, and air conditioning system. It proposes to construct a mathematical model to achieve autonomous air conditioning adjustment by using the mapping relationship between the input parameters and output parameters of neural network training samples. The core lies in the optimization of air conditioning parameters by intelligent algorithms. This invention does not involve the dynamic switching mechanism of communication mode, the dynamic code library protocol adaptation function based on blind matching, or the energy-saving optimization strategy of MPC algorithm combined with temperature change rate.

[0006] Therefore, this invention discloses a multifunctional air conditioning parameter control system, method, and smart socket based on dual-mode communication. Summary of the Invention

[0007] This invention provides a multi-functional air conditioner parameter control system, method, and smart socket based on dual-mode communication, to solve the existing technical problems of frequent jitter during dual-mode communication switching, inability to adaptively match infrared protocols, low energy efficiency in temperature control, and insufficient security protection of smart sockets.

[0025] Step S2: Monitor the 4G signal strength through the dual-mode switching unit. When the 4G signal strength is <-90dBm, switch to infrared communication mode. When the 4G signal strength is >-85dBm for 10 seconds, switch back to 4G mode.

[0026] Step S3: The dynamic code library learning module polls and sends control commands for the air conditioning parameters of each model of air conditioning equipment. When a temperature change ≥0.5℃ or a power change ≥10W is detected, the matching control protocol is locked and the corresponding infrared command code set and protocol identifier are generated as optimized protocol parameters and sent to the smart socket for storage.

[0027] Step S4: Skip the air conditioner parameter control instruction update when the temperature change rate is <3%; generate energy-saving instructions based on power consumption data, ambient temperature and humidity data and user-set parameters through the MPC algorithm.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0051] Figure 2 A flowchart illustrating a multi-functional air conditioner parameter control method based on dual-mode communication, provided in an embodiment of the present invention. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0053] Please refer to Figure 1 This is a system architecture diagram of a multi-functional air conditioning parameter control system based on dual-mode communication provided in an embodiment of the present invention.

[0054] This embodiment provides a multi-functional air conditioning parameter control system based on dual-mode communication, including:

[0055] Main control module, parameter acquisition module, dual-mode communication module, dynamic code library learning module, control and energy consumption module, smart socket and user terminal;

[0056] The main control module is used to receive air conditioning parameter control commands from user terminals and process the air conditioning parameter control commands, environmental parameters collected by the parameter acquisition module, power consumption data of the air conditioning equipment uploaded by the smart socket, and air conditioning equipment operating status information obtained from analysis.

[0057] The parameter acquisition module includes a temperature sensor and a humidity sensor, used to collect environmental parameters;

[0058] Dual-mode communication module, including:

[0059] The 4G communication unit is used to enable remote data interaction between the main control module and the smart socket and user terminal;

[0060] Infrared communication unit, used to generate infrared command compression code;

[0061] Dual-mode switching unit, used to switch communication modes according to 4G network signal strength;

[0062] The dynamic code library learning module is used to generate optimized protocol parameters and send them to the smart socket to configure the blind matching unit;

[0063] The control and energy consumption module includes:

[0064] An event-triggered control unit is used to skip the update of air conditioning parameter control commands when the temperature change rate is <3%;

[0065] The AI ​​energy-saving optimization unit is used to generate energy-saving instructions;

[0066] The smart socket is used to collect power consumption data of the air conditioning equipment and analyze it to obtain the operating status information of the air conditioning equipment, upload it to the main control module, and execute the power control commands issued by the main control module.

[0067] The user terminal is used to send air conditioning parameter control commands to the main control module and display the air conditioning equipment operating status information and power consumption data fed back by the main control module.

[0068] It should be noted that when processing data, the main control module first verifies the validity of the environmental data from the parameter acquisition module (removing outliers that exceed a reasonable range), and then combines it with the power consumption data and operating status information uploaded by the smart socket to form a unified basis for control decisions.

[0069] User terminal air conditioning parameter control commands (such as setting the temperature to 26℃) are transmitted encrypted via HTTPS protocol.

[0070] Environmental parameters are obtained by the parameter acquisition module at a frequency of 1Hz through I 2 C-bus transmission.

[0071] The power consumption data and air conditioner operating status information uploaded by the smart socket are encapsulated into MQTT message packets, which include timestamps and device IDs.

[0072] The main control module processes data through a priority queue: control commands > safety alarms > environmental parameters > power consumption data.

[0073] The 4G communication unit utilizes the existing 4G network infrastructure to achieve remote data interaction between the main control module, smart sockets, and user terminals, ensuring that the system can still communicate and control stably and efficiently over a large range.

[0074] The infrared communication unit generates infrared command compression codes for short-range control scenarios, enabling direct control of air conditioning equipment via infrared signals, thus compensating for the shortcomings of 4G communication in short-range low-latency control.

[0075] The dual-mode switching unit can automatically switch communication modes according to the 4G network signal strength, ensuring the communication stability and reliability of the system in different network environments.

[0076] The infrared command compression code adopts a universal encoding format (such as a compression algorithm based on Manchester encoding) to ensure that the smart socket can accurately parse and match the pre-stored infrared code library.

[0077] The temperature change rate judgment of the event-triggered control unit and the MPC algorithm of the AI ​​energy-saving optimization unit are coordinated in a timing manner. First, invalid adjustment demands are filtered out by event triggering, and then the AI ​​unit generates refined energy-saving instructions for valid demands.

[0078] The smart socket analyzes the air conditioner's operating status information and extracts features from power consumption data (such as identifying the on / off status by power surges and distinguishing cooling / heating modes by power fluctuation patterns), achieving state inversion without the need for additional sensors.

[0079] The user terminal and the main control module use encrypted transmission for command interaction (command encryption based on the AES algorithm) to ensure the security of control commands and prevent unauthorized operations.

[0080] I. Dual-mode switching unit:

[0081] When the 4G network signal strength is <-90dBm, switch to infrared communication unit; when the 4G network signal strength is >-85dBm for 10 seconds, switch back to 4G communication unit.

[0082] It should be noted that when switching from 4G mode to infrared mode, the system caches 4G commands that have been received but not yet executed before the switch, and resends them through the infrared communication unit after the infrared mode is activated to ensure the continuity of command execution. New air conditioning parameter control commands after the switching action is triggered will be sent directly through the currently activated infrared communication unit without caching or waiting, so as to ensure the immediate response to new commands.

[0083] During the switching between the two communication modes, the main control module will push a mode switching notification to the user terminal to synchronize the current communication status, and the switching action will not interrupt the normal operation of the air conditioning equipment.

[0084] II. Blind Matching Unit:

[0085] The blind matching unit is used to poll and send the corresponding air conditioning parameter control commands for each model of air conditioning equipment when it receives air conditioning parameter control commands. It detects changes in the operating status information of the air conditioning equipment through the power consumption data uploaded by the parameter acquisition module and the smart socket. When it is detected that the air conditioning equipment responds to a certain air conditioning parameter control command and causes a temperature change ≥0.5℃ or a power change ≥10W, it determines that the control protocol corresponding to the air conditioning parameter control command matches the air conditioning equipment, locks the control protocol as the base protocol for infrared communication, and sends the infrared command code set and protocol identifier corresponding to the control protocol as optimized protocol parameters to the smart socket for storage.

[0086] It should be noted that when the blind matching unit polls the instructions, the polling interval is 500ms. The polling instruction set is arranged in descending order of air conditioner brand market share to shorten the protocol matching time. The generated protocol identifier includes brand code + instruction set version number, which can be dynamically updated to avoid expired protocols being executed by mistake.

[0087] III. AI Energy Saving Optimization Unit:

[0088] The AI ​​energy-saving optimization unit generates energy-saving instructions based on power consumption data collected by the smart socket, ambient temperature and humidity data from the parameter acquisition module, and user-defined parameters, using an MPC algorithm.

[0089] Energy-saving commands for air conditioner operating parameters are sent to the air conditioning equipment via the infrared communication unit of the dual-mode communication module;

[0090] Energy-saving commands for the air conditioner's power supply status are sent to the smart socket via the 4G communication unit of the dual-mode communication module.

[0091] It should be noted that the MPC algorithm of the AI ​​energy-saving optimization unit adopts a rolling optimization strategy, with the prediction time domain set to 30 minutes (divided into 6 control cycles at 5-minute intervals). By updating the ambient temperature and humidity and power consumption data in real time, the prediction model is corrected to ensure that the energy-saving instructions match the actual operating conditions.

[0092] User-defined parameters include target temperature range (e.g., 24-26℃) and energy-saving priority (e.g., "comfort priority" or "energy-saving priority"). The algorithm will dynamically allocate the weight ratio of temperature deviation and energy consumption according to the priority.

[0093] Energy-saving commands for air conditioning operating parameters (such as temperature fine-tuning and fan speed adjustment) adopt an incremental sending strategy, with each adjustment not exceeding ±1℃ or one fan speed level, to avoid energy consumption fluctuations caused by sudden parameter changes.

[0094] When air conditioner parameter control commands are sent via infrared communication, 4G power supply commands will be delayed until the current operating command is completed before being sent to avoid command conflicts.

[0095] IV. MPC Algorithm:

[0096] In the cost function of the MPC algorithm, the weight coefficient λ(k) is dynamically adjusted with the rate of temperature change, as expressed by the formula:

[0097] λ(k)=λ max -(λ max -λ min )·e -β·|r(k)|

[0098] Where λ(k) is the weight coefficient at the k-th sampling time; λ max λ is the upper limit of the weighting coefficient.min λ is the lower limit of the weighting coefficient. max and λ min The constant is 0 < λ. min <λ max <1; e -β·|r(k)| β is the smooth transition term of exponential decay, β>0 is the decay coefficient, and r(k) is the rate of temperature change.

[0099] It should be noted that in similar studies of air conditioning load forecasting and MPC, the attenuation coefficient β is usually taken in the range of 0.01 to 0.1, and a value of β = 0.05 can be taken to balance response speed and stability, making it easy for those skilled in the art to directly reuse or fine-tune.

[0100] Upper limit of weight coefficient λ max and lower limit value λ min The value range is preset according to the air conditioner type (fixed frequency / inverter frequency) and supports users to fine-tune it through the terminal to adapt to the usage scenario.

[0101] The MPC algorithm recalculates λ(k) in each sampling period and updates the cost function by combining the latest temperature change rate and electricity consumption data, thus achieving real-time dynamic optimization.

[0102] V. Rate of temperature change:

[0103] The formula for calculating the rate of temperature change r(k) is as follows:

[0104]

[0105] Among them, T (k) T represents the ambient temperature collected at the k-th sampling time. (k-1) T represents the ambient temperature collected at the (k-1)th sampling time. (k) -T (k-1) This represents the absolute temperature change between two adjacent sampling times.

[0106] It should be noted that the sampling period between adjacent sampling times can be set according to actual needs to ensure that temperature change trends are captured without excessively consuming system computing resources. Before calculation, the ambient temperature T collected should be... (k) and T (k-1) Preprocessing (removing values ​​that exceed the physical reasonable range, or smoothing noise by averaging three consecutive samples) is performed to avoid misjudgment of the rate of change caused by abnormal data.

[0107] Please refer to Figure 2 A flowchart illustrating a multi-functional air conditioner parameter control method based on dual-mode communication, provided in an embodiment of the present invention.

[0108] A multi-functional air conditioner parameter control method based on dual-mode communication, the method comprising:

[0109] Step S1: Receive air conditioning parameter control instructions from the user terminal through the main control module, and simultaneously acquire ambient temperature and humidity data from the parameter acquisition module, as well as power consumption data and operating status information of the air conditioning equipment uploaded by the smart socket.

[0110] Step S2: Monitor the 4G signal strength through the dual-mode switching unit. When the 4G signal strength is <-90dBm, switch to infrared communication mode. When the 4G signal strength is >-85dBm for 10 seconds, switch back to 4G mode.

[0111] Step S3: The dynamic code library learning module polls and sends control commands for the air conditioning parameters of each model of air conditioning equipment. When a temperature change ≥0.5℃ or a power change ≥10W is detected, the matching control protocol is locked and the corresponding infrared command code set and protocol identifier are generated as optimized protocol parameters and sent to the smart socket for storage.

[0112] Step S4: Skip the air conditioner parameter control instruction update when the temperature change rate is <3%; generate energy-saving instructions based on power consumption data, ambient temperature and humidity data and user-set parameters through the MPC algorithm.

[0113] Step S5: The smart socket performs power on / off operation; when infrared communication mode is used, the air conditioner responds to the infrared command, and the air conditioner's operating status information and power consumption data are fed back to the user terminal through the main control module.

[0130] In the dual-mode communication circuit assembly, the circuit layout of the 4G communication chip and the infrared transceiver is isolated from each other (spacing ≥ 5cm) to avoid electromagnetic interference.

[0131] The infrared transmitter is installed in the center of the front of the housing to ensure that the signal path to the air conditioner's infrared receiver window is unobstructed.

[0132] The UART protocol allows for configurable baud rates (such as 115200) in data transmission and employs a parity check mechanism to ensure the accuracy of command and data interaction.
