[0002] With the rapid development of smart home technology, intelligent control of home appliances has become an important means of improving the convenience of life. Users can send control commands to home appliances such as air conditioners, lights, and smart curtains through various control devices such as remote controls and voice assistants to control these appliances. However, different manufacturers and models of home appliances often use different custom communication protocols, and their command formats and parameter encoding methods vary greatly, making it difficult for third-party control devices to achieve compatible control.

[0003] In related technologies, a communication protocol specification library is built by collecting communication protocol specifications from various home appliances to adapt to different home appliances and complete control operations as much as possible. Alternatively, for third-party control devices with infrared functionality, infrared code learning technology can be used to record the infrared signals of the control home appliances and directly complete the control operations.

[0004] However, if the communication protocol used by the newly added home device is not recorded in the communication protocol specification library, or if the third-party control device does not have infrared functionality, then the home device cannot be controlled. Summary of the Invention

[0026] The embodiments of the present invention have the following advantages: This invention, in its embodiments, monitors communication data sent from a control device to home appliances. This communication data includes command sequences. Multiple command sequences are analyzed and processed to determine which fields represent parameter components without requiring manual review of protocol documentation. Next, the status change information of the home appliances after receiving the communication data is acquired. The values ​​of the parameter fields are matched with this status change information to establish a mapping relationship between the parameter field values ​​and the status change information. Finally, the specific values ​​of the command parameter fields are matched and associated with the actual status changes of the home appliances to determine the functional meaning of each command sequence.

This establishes a mapping relationship between functional semantics and the parameter fields of the command sequence. This allows for control of the home appliances when subsequent commands with user intent are received, without prior knowledge of the home appliances' communication protocols; the corresponding command sequence can be directly derived through this mapping relationship.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] With the rapid development of smart home technology, intelligent control of home appliances has become an important means of improving the convenience of life. Users can send control commands to home appliances such as air conditioners, lights, and smart curtains through various control devices such as remote controls and voice assistants to control these appliances. However, different manufacturers and models of home appliances often use different custom communication protocols, and their command formats and parameter encoding methods vary greatly, making it difficult for third-party control devices to achieve compatible control.

[0033] In related technologies, a communication protocol specification library is built by collecting communication protocol specifications from various home appliances to adapt to different home appliances and complete control operations as much as possible. Alternatively, for third-party control devices with infrared functionality, infrared code learning technology can be used to record the infrared signals of the control home appliances and directly complete the control operation. However, if the communication protocol used by a newly added home appliance is not recorded in the communication protocol specification library, or if the third-party control device does not have infrared functionality, then the home appliance cannot be controlled.

[0034] This invention pertains to the application of emerging software and new information technology services in the smart home field, specifically involving protocol adaptation and command conversion software technology in smart home scenarios. One of the core concepts of this invention lies in automatically analyzing and determining the parameter fields in the command sequence, and then establishing a mapping relationship between functional semantics and parameter fields. This allows for the control of home devices when subsequent user-intentioned command information is received, without prior knowledge of the communication protocol of the home devices; the corresponding command sequence can be directly converted through this mapping relationship.

[0035] Figure 1 This is a flowchart of the steps of a home appliance instruction conversion method provided in an embodiment of the present invention.

[0036] like Figure 1 As shown, the method may specifically include the following steps: Step 101: Monitor the communication data sent by the control device to the home appliance, the communication data including a sequence of instructions; In this embodiment of the invention, home appliances refer to electrical devices with communication interfaces that can be controlled remotely or locally, such as air conditioners, air purifiers, fans, electric curtains, and smart lights. Control devices refer to devices capable of sending control commands to home appliances, such as remote controls, wired controllers, smart panels, and mobile phones. Communication between the control device and the home appliances occurs via wired bus or wireless signals. Communication data refers to the raw binary data frames transmitted between the control device and the home appliances, including instruction sequences. The format, length, and verification method of these data frames may vary depending on the manufacturer or model. As an example, the instruction sequence could be 0xA1 0x05 0x01 0x00 0xFF.

[0037] It is worth noting that the application scenario of this invention is when a third-party control device needs to control home appliances. It can first listen to the communication data sent by other control devices to the home appliances, thus providing a data foundation for subsequent command conversion. For example, a user's home has an air conditioner (home appliance) installed, along with its original remote control (control device). The user wants to use a smart gateway (third-party control device) in their home to control the air conditioner.

[0038] As an example, if a smart gateway is used as the implementing entity of the method of this invention, it can connect in parallel to the communication bus, such as UART, between other control devices and home appliances, thereby monitoring the communication data sent by the control devices to the home appliances. This monitoring refers to capturing signals on the bus in read-only mode, without changing the original communication path or interfering with the communication content.

[0039] Step 102: Analyze and process multiple instruction sequences to determine the instruction structure of the instruction sequences, wherein the instruction structure includes parameter fields; After obtaining multiple instruction sequences, statistical analysis is performed on them to automatically identify the compositional patterns of the instruction sequences, especially to delineate the parameter fields for subsequent mapping relationships.

[0040] In some embodiments, the instruction sequence comprises multiple bytes; In some embodiments, step 102 specifically includes the following sub-steps: Sub-step S11: Determine the frequency of occurrence of byte values ​​appearing on the same byte in the plurality of instruction sequences; Different manufacturers or models of home appliances may use different instruction formats, but an instruction sequence usually includes: a fixed instruction header, one or more variable parameter fields, and an optional fixed terminator. Therefore, this invention considers performing byte-by-byte frequency analysis on multiple instruction sequences as samples to analyze and identify the instruction structure of the instruction sequence.

[0041] Starting from byte 0, for each byte position, count all byte values ​​that appear at that position in all instruction sequences, and calculate the proportion of the occurrences of each byte value to the total number of samples at that position as the occurrence frequency.

[0042] As an example, there are N instruction sequences. For position i, we count the byte value distribution of the N instructions at that position to obtain the frequency of each byte value v, f(v) = count(v) / N.

[0043] Sub-step S12: If the frequency of occurrence of the same byte value on a byte is greater than the first frequency, then the byte is determined to belong to a fixed field; The first frequency is a relatively high preset frequency, such as 90%. When the frequency of a specific byte value at a certain byte position exceeds 90%, it can be understood that the byte remains almost unchanged in all instruction sequences, and therefore the byte is determined to belong to a fixed field.

[0044] As an example, there are 100 instruction sequences. At position 0, the byte value 0xA1 appears 98 times, with a frequency of 98%, which is greater than the first frequency of 90%. Therefore, position 0 is determined to be a fixed field, and its field value is fixed as 0xA1.

[0045] Sub-step S13: If, among all the byte values ​​that appear on a byte, the frequency of the byte value with the highest frequency is less than the second frequency, then the byte is determined to belong to the parameter field; the second frequency is less than the first frequency.

[0046] The second frequency is a preset frequency that is lower than the first frequency. For example, the second frequency can be set to 70%. When the frequency of the byte value that appears most frequently at a certain byte position is also lower than the second frequency, it can be understood that the byte varies greatly in different instruction sequences, and therefore the byte is determined to belong to the parameter field.

[0047] As an example, there are 100 instruction sequences. At position 4, the byte values ​​0x01, 0x02, 0x03, and 0x04 appear 32, 28, 25, and 15 times respectively. The highest frequency of occurrence is 32%, which is less than the second highest frequency of 70%. Therefore, position 2 is determined to be a parameter field.

[0048] Step 103: Obtain the status change information of the home device after receiving the communication data; In order to establish a mapping relationship between the parameter fields of the command sequence and the specific control functions, it is necessary to obtain the state changes of the home appliances after receiving the command sequence. The state change information describes the state changes that occur in the home appliances after executing the command, such as the temperature dropping by one degree or the mode switching from cooling to heating.

[0049] In some embodiments, the communication data further includes time information; In some embodiments, step 103 specifically includes the following sub-steps: Sub-step S21: Based on the time information of the communication data, determine the first state information of the home device before receiving the communication data and the second state information after receiving the communication data from the continuously acquired state information of the home device; During operation, the gateway continuously records the status information of home devices and their corresponding timestamps. When the gateway receives communication data sent to the home devices by other control devices, it retrieves the most recent status information before that moment from the continuously recorded status information based on the time information of the communication data, and retrieves the status information after that moment for a period of time, such as 3 seconds, as the second status information.

[0050] As an example, the gateway maintains a state information cache queue. When a sequence of instructions is received, its timestamp is determined to be T. The state information whose timestamp is less than and closest to T is retrieved from the cache queue as the first state information. Simultaneously, a timer is set to retrieve the last state information whose timestamp falls within the range (T, T+Δt) from the cache queue at time T+Δt, for example, Δt = 3000 milliseconds, as the second state information.

[0051] Sub-step S22: Determine the state change information based on the first state information and the second state information.

[0052] The second state information is compared with the first state information to determine the difference between them, thus obtaining state change information. State change information can be represented as temperature difference, the mode before and after a mode switch, etc., and a mapping relationship is subsequently established between the functional meaning of the subsequent instruction sequence and the instruction sequence itself.

[0053] As an example, if the first state information is cooling mode 26℃ and the second state information is cooling mode 27℃, then the state change information is that the temperature increases by 1℃.

[0054] In some embodiments, the method further includes: continuously acquiring status information of the home device; In some embodiments, continuously acquiring the status information of the home device includes the following specific steps: Obtain the status sequence broadcast by the home device; the status sequence includes a status field; Obtain the mapping relationship between the field values ​​of the status field and the status of the home devices; Based on the status field and the mapping relationship between the field value of the status field and the status of the home device, the status of the home device corresponding to the status field is determined, and status information is generated.

[0055] In real-world applications, home appliances such as air conditioners periodically broadcast their current status to the communication bus, for example, sending a status data frame every 500 milliseconds. This status sequence is the raw byte sequence of the status data frame, which may include status fields indicating temperature, mode, fan speed, on / off status, etc. The gateway connects to the bus in parallel and obtains these status sequences in read-only mode.

[0056] In some embodiments, the mapping relationship between the field value of the status field and the status of the home device is determined in the following manner: Obtain device status description information provided by the user, which represents the state of the home device after executing a sequence of instructions; obtain the state sequence of the home device after executing the sequence of instructions; analyze and process multiple state sequences to determine the state fields in the state sequences; match the field values ​​of the state fields with the device status description information to determine the mapping relationship between the field values ​​of the state fields and the state of the home device indicated by the device status description information.

[0057] In practical applications, users can provide device status descriptions after performing certain operations on home appliances via mobile apps or web interfaces. For example, after a user sets an air conditioner to heating mode using a remote control, they can select the "Heating Mode" tab on the app. This tab serves as the device status description, which is then recorded by the gateway. Simultaneously, the gateway also acquires the status sequence broadcast by the home appliances after this operation.

[0058] By collecting state sequence samples under different states through the above steps, and then performing byte-by-byte comparative analysis on these sequences, we can compare which byte positions have changed in the states represented by different state description information, thereby determining the state fields in the state sequence.

[0059] As an example, when the device status description information is cooling, the status sequence is A2 0C 1A 01 02 00 FFFF; when the device status description information is heating, the status sequence is A2 0C 1A 02 02 00 FF FF; when the device status description information is air supply, the status sequence is A2 0C 1A 03 02 00 FF FF. Therefore, comparative analysis shows that position 3 is a status field, specifically a status field reflecting the air conditioning mode.

[0060] Next, the values ​​of the status field are matched with the device status description information to determine the mapping relationship between the status field values ​​and the status of the home appliances indicated by the device status description information. Therefore, when a new status sequence is subsequently obtained, the status of the home appliances corresponding to the status field in that status sequence can be directly determined based on this mapping relationship, thus generating status information.

[0061] Step 104: Match the field values ​​of the parameter fields with the state change information to establish a mapping relationship between the field values ​​of the parameter fields and the state change information; After determining the parameter fields in the instruction sequence and the state change information corresponding to each instruction sequence through the previous steps, this step associates and matches the two to establish a mapping relationship between the instruction sequence and the specific functional semantics.

[0062] In some embodiments, step 104 specifically includes the following sub-steps: Sub-step S31: For multiple instruction sequences, establish a candidate mapping relationship between the field values ​​of the parameter fields and the state change information of the corresponding instruction sequences; Because bus communication may be subject to interference or fluctuations in the air conditioner's own state, this invention considers that the reliability of a single matching result may be low. Therefore, a multiple verification mechanism is adopted. Only when the same mapping relationship appears multiple times simultaneously is it determined to be a stable mapping relationship.

[0063] For each collected instruction sequence, the gateway extracts the field value of its parameter field, which can be a value consisting of one or more bytes. At the same time, it obtains the state change information corresponding to the instruction sequence, and then associates the two to form a candidate mapping relationship.

[0064] In practical applications, candidate mappings can be temporarily stored as key-value pairs. Specifically, the gateway can maintain a mapping table to record the state change information corresponding to each parameter field value and its occurrence count. When processing a new instruction sequence, the gateway searches the mapping table based on the instruction's parameter field value. If the key already exists in the table, it checks whether the current state change information matches the record in the table; if they match, the mapping count is incremented; if they do not match, a conflict is recorded; if the key does not exist in the table, a new candidate mapping is created.

[0065] Sub-step S32: When the number of times a candidate mapping relationship is established between the field value of the same parameter field and the same state change information reaches a preset number, the mapping relationship between the field value of the parameter field and the state change information is determined.

[0066] The specific value of the preset number of times can be set according to the actual situation, and this invention does not impose any restrictions on it. As an example, if the preset number of times is 3, then only when the mapping between the same parameter field value and the same state change information appears repeatedly 3 times will the candidate mapping relationship be recognized as a formal mapping relationship for use in subsequent instruction conversion.

[0067] Step 105: Receive instruction information for controlling the home appliances; After establishing the mapping relationship between parameter field values ​​and state change information in the preceding steps, it can be understood that the gateway has basically acquired the ability to understand command semantics. It can then enter the control phase, where the gateway receives control requests from upper-layer applications or user interfaces, that is, command information used to control the home appliances.

[0068] It should be noted that the command information is a high-level control command independent of the underlying communication protocol. As an example, the command information could be a control command issued by the user through a mobile application or a control command generated by a voice assistant after parsing the user's voice. Unlike the underlying command sequence, the command information received in this step is independent of the specific communication protocol. That is, the upper-layer application issuing the command information does not need to know whether the air conditioner uses a UART bus or infrared remote control, nor does it need to understand the meaning of a certain value in the command; it only needs to send a semantic control request. The gateway, acting as an intermediate layer, is responsible for converting the high-level command information into a low-level command sequence, thus ensuring compatibility with the differences in protocols among various home appliances.

[0069] In practical applications, instruction information can uniformly adopt a structured data format, such as JSON or XML. As an example, an instruction message might be JSON: { "cmd": "set_mode", "value": "heat"}.

[0070] Step 106: Determine the instruction sequence corresponding to the instruction information based on the instruction information and the mapping relationship; In some embodiments, the instruction structure further includes fixed fields; As can be understood, fixed fields are the parts of the instruction sequence whose values ​​remain unchanged, such as the instruction header and end-of-line character. Once the parameter field values ​​are determined, the complete instruction sequence can be obtained by simply concatenating the fixed fields with the parameter fields in sequence.

[0071] In some embodiments, step 106 specifically includes the following sub-steps: Sub-step S41: Determine the state change information corresponding to the instruction information as the target state change information; The gateway first parses and processes the received command information to determine its control intent and converts it into standardized state change information, which serves as the target state change information for this command conversion. For example, the command information might be: "Set the temperature to 24℃." The gateway needs to consider the actual state of the current home appliances to determine the required state change. If the current temperature is 26℃ and the command information requests a setting of 24℃, then the target state change information is determined to be: "Decrease the temperature by 2℃."

[0072] Sub-step S42: Based on the target state change information and the mapping relationship, determine the field value of the parameter field corresponding to the target state change information; In the mapping relationship between the field values ​​of the instruction sequence parameter fields and the state change information established in the previous steps, query the state change information that matches the target state change information and retrieve the field values ​​of the corresponding parameter fields.

[0073] Sub-step S43: Based on the instruction structure, combine the field values ​​of the fixed field and the parameter field to obtain the instruction sequence corresponding to the instruction information.

[0074] After obtaining the parameter field values ​​corresponding to the target state change information, the fixed field values ​​and parameter field values ​​are combined in sequence according to the instruction structure determined in the previous steps to obtain a complete instruction sequence.

[0075] Step 107: Send the instruction sequence to the home appliance to control the home appliance to perform the corresponding operation.

[0076] After determining the instruction sequence corresponding to the instruction information, the gateway sends the instruction sequence to the communication link, where it is received and executed by the home appliance to achieve the user's desired control effect. In practical applications, when the communication link is a wired bus such as UART, the gateway can output each byte of the instruction sequence to the bus sequentially through its UART transmit pin.

[0077] This invention applies a novel information technology service method to the protocol analysis and instruction conversion of home appliances. By learning the communication protocols of home appliances through software methods, it enables adaptive control of devices with unknown protocols, solving the problem of being unable to control corresponding home appliances due to an incomplete communication protocol specification library.

[0078] In some embodiments, the method further includes: After the instruction sequence is sent to the home appliance, the system monitors whether the status change information of the home appliance matches the instruction information. If the status change information of the home appliance does not match the instruction information, it is determined to be a control error. If the number of control errors reaches a preset number, the mapping relationship corresponding to the instruction information is deleted.

[0079] After the gateway sends the command sequence, it continues to acquire the status information of home devices and observes whether the status of the home devices has changed as expected within a reasonable time window, such as within 3 seconds after sending the command. When a discrepancy is detected between the actual status change and the expectation, a control error is identified and recorded. When the number of control errors reaches a preset number, the mapping relationship corresponding to that command information is deleted.

[0080] In one embodiment, the gateway maintains a reliability counter for the mapping relationship between each parameter field value and state change information. The initial reliability can be set to 0 or a positive value. If the control is successful, the reliability of the corresponding mapping relationship is increased by 1; if the control fails, the reliability of the corresponding mapping relationship is decreased by 1. When the reliability reaches the set lower limit, the mapping relationship is determined to be unreliable and is deleted from the mapping relationship table.

[0081] In some embodiments, the method further includes: When a firmware upgrade event for the home device is detected, multiple mapping relationships are verified. If the number of failed verification mapping relationships reaches a preset number, the mapping relationships for the home device are deleted and re-established.

[0082] During the long-term use of home appliances, there may be situations where it is necessary to upgrade the device firmware. However, firmware upgrades may change the instruction format, parameter encoding rules, or status feedback method of the device's communication protocol, which may lead to the failure of established mapping relationships.

[0083] To address this, the present invention considers detecting firmware upgrade events of the home appliances. Specifically, the gateway can periodically query the firmware version number of the home appliances via a dedicated command. When the version number is found to be inconsistent with the previously recorded version number, it is determined that a firmware upgrade has occurred. Alternatively, the gateway can continuously monitor the status sequence broadcast by the home appliances. If it finds significant changes in the length of the status data frame or the values ​​of fixed fields, and these changes remain stable across multiple consecutive samples, it is determined that a firmware upgrade or protocol change may have occurred.

[0084] Upon detecting a firmware upgrade event, the gateway performs verification. Specifically, it selects a portion of the mapping relationships from the current mapping table, actively sends the corresponding command sequence, and then determines whether the actual state change matches the expected value in the mapping relationship. If they match, the verification is considered successful; otherwise, it is considered a failure.

[0085] If the number of failed verifications of the mapping relationship reaches a preset number, it is considered that the firmware upgrade has indeed caused a large-scale change in the protocol, and the mapping relationship for the home device is deleted and re-established.

[0086] This invention, in its embodiments, monitors communication data sent from a control device to home appliances. This communication data includes command sequences. Multiple command sequences are analyzed and processed to determine which fields represent parameter components without requiring manual review of protocol documentation. Next, the status change information of the home appliances after receiving the communication data is acquired. The values ​​of the parameter fields are matched with this status change information to establish a mapping relationship between the parameter field values ​​and the status change information. Finally, the specific values ​​of the command parameter fields are matched and associated with the actual status changes of the home appliances to determine the functional meaning of each command sequence.

[0087] Building upon this foundation, when subsequent commands for controlling home appliances are received, the corresponding command sequence is determined based on the command information and the mapping relationship. This command sequence is then sent to the home appliances to control them and execute the corresponding operations. By monitoring the communication data between the control device and the home appliances, the parameter fields in the command structure are automatically analyzed, and their values ​​are matched with actual device state changes. This establishes a mapping relationship between functional semantics and the parameter fields of the command sequence. This allows for control of the home appliances when subsequent commands with user intent are received, without prior knowledge of the home appliances' communication protocols; the corresponding command sequence can be directly derived through this mapping relationship.
