[0002] With the rapid development of the internet, more and more isolated information islands have been connected. The Internet of Things is an information carrier based on the internet, traditional telecommunications networks, and other technologies.

[0003] In the wired communications field of the Internet of Things, existing power carrier technology can transmit data without the need for a data bus. It is more commonly used in the power industry or street lighting. It has a broadcast function and can send instructions to many devices at once, but lacks grouping and scene functions, making it inconvenient for intelligent control. While DALI (Digital Addressable Lighting Interface) digital lighting technology has grouping and scene functions, its bandwidth is too narrow, with a maximum of 16 groups and 16 scenes.

In addition, the laying and debugging of data cables are very demanding, and the cost and time are difficult to control.

[0046] In the wired communications field of the Internet of Things, existing power carrier technology can transmit data without the need for a data bus. It is more commonly used in the power industry or street lighting. It has a broadcast function and can send instructions to many devices at once, but lacks grouping and scene functions, making it inconvenient for intelligent control. While DALI (Digital Addressable Lighting Interface) digital lighting technology has grouping and scene functions, its bandwidth is too narrow, with a maximum of 16 groups and 16 scenes. This cannot adapt to the application scale and real-time requirements of the Internet of Things. In addition, the laying and debugging of data cables are very demanding, and the cost and time are difficult to control.

[0047] Therefore, in order to solve the above problems, the present invention provides an Internet of Things control method in a power carrier environment.

Then, based on the response instruction, the power carrier instruction is controlled to be retransmitted. The present invention uses response and caching technology to make the power carrier group and scenario data instructions more reliable through a retransmission mechanism for specific batches of individuals.

[0048] Exemplary Methods

[0049] This embodiment provides an Internet of Things control method under a power line carrier environment, and this embodiment can be applied to Internet of Things devices. Figure 1 As shown, the method includes the following steps:

[0050] Step S100: Acquire a power carrier instruction broadcasted on the Internet of Things; wherein the power carrier instruction includes a configuration instruction and a control instruction, the configuration instruction includes an individual configuration instruction, a group configuration instruction, and a scene configuration instruction, and the control instruction includes an individual control instruction, a group control instruction, and a scene control instruction;

[0051] Power line communication (PLC), short for Power Line Communication, is a communication method unique to power systems. It utilizes existing power lines to transmit analog or digital signals at high speed via carrier waves. The key advantage of PLC is that it eliminates the need for a new network; data transmission can be performed as long as there are power lines. This embodiment integrates grouping and scene functions into the power line carrier environment and leverages the broadband characteristics of the power line carrier to expand digital lighting technology to various IoT sensors and actuators. This eliminates the need for additional physical bus deployment and reduces construction requirements, significantly saving engineering manpower and resources. This embodiment adapts digital lighting grouping and scene technologies to the power line carrier system, adding features such as simultaneous multi-target command transmission and accurate data response and confirmation. This creates an IoT control method suitable for a variety of specialized applications, including lighting, curtains, various alarms, and valve adjustment.

[0052] Specifically, this embodiment configures and controls IoT devices by broadcasting power carrier commands over the power grid. Configuration commands configure individual IoT devices, groups, and scenarios, enabling batches of IoT devices to be grouped and set up for specific scenarios. Control commands control individual IoT devices, groups, and scenarios to complete specific control actions.

[0053] For example, power carrier commands broadcast on the IoT include individual configuration commands A1, used to configure the parameters of individual IoT devices; group configuration commands A2, used to assign individual IoT devices to specific IoT device groups; and scenario configuration commands A3, used to group IoT devices into specific scenarios. Control commands include individual control commands B1, used to control individual IoT devices; group control commands B2, used to control all IoT devices in a specific IoT device group; and scenario control commands B3, used to control all IoT devices in a specific IoT device scenario.

[0054] Step S200: performing configuration or executing control actions according to the power carrier instruction, and sending a response instruction;

[0055] Specifically, after an IoT device receives a power carrier instruction broadcast from a power carrier communication network, if it determines that it is the target of the power carrier instruction, it needs to configure or execute control actions according to the power carrier instruction, and send a response instruction to the sender of the power carrier instruction to declare that it has received the power carrier instruction, so as to improve the reliability of instruction transmission.

[0056] For example, when the IoT device C1 receives the individual configuration instruction A1 broadcast on the IoT, it executes A1 and sends a response instruction D1 to the sender of the power carrier instruction to declare that the IoT device C1 has received the individual configuration instruction A1 and executed the A1 instruction.

[0057] In one implementation, step S200 in this embodiment includes the following steps:

[0058] Step S201, the Internet of Things control method in a power carrier environment according to claim 1, characterized in that the configuration or execution of the control action according to the power carrier instruction, the sending of the response instruction, and the obtaining of the response instruction include:

[0059] Step S202: If the power carrier instruction is the individual configuration instruction, obtain the designated IoT device individual according to the individual ID in the individual configuration instruction; wherein the individual configuration instruction includes an individual configuration instruction code, a serial number, an individual ID, a number of configuration parameters, a configuration parameter name, and a configuration parameter value;

[0060] Step S203: setting the parameters of the individual IoT device according to the configuration parameter name and configuration parameter value in the individual configuration instruction;

[0061] Step S204: Control the designated IoT device to issue a response instruction based on the serial number and the individual ID; wherein the response instruction includes a response instruction code, the serial number, the individual ID, and status information.

[0062] Specifically, the format of the individual configuration instruction in this embodiment is individual configuration instruction code + serial number + individual ID + number of configuration parameters + multiple (configuration parameter name: configuration parameter value). The individual configuration instruction code is SET, which represents the instruction to set the individual. The serial number is a numerical identifier uniquely assigned to each power carrier instruction, which is used to distinguish which instruction it is. The individual ID is a unique identification code for each individual IoT device. The number of configuration parameters is used to indicate how many configuration parameter pairs consisting of configuration parameter name: configuration parameter value are contained in this individual configuration instruction. Configuration parameter name: configuration parameter value indicates the parameter name and corresponding parameter value that are required to be added to the individual IoT device in the individual configuration instruction. It can be single or multiple. The configuration parameter name and parameter value are defined by the actual IoT professional. If there are multiple parameter names and corresponding parameter values, and they are not equal to the number in the number of configuration parameters, the larger number between the number of configuration parameters and the actual number of configuration parameter names: configuration parameter values ​​determines the number of parameters that need to be configured for the individual IoT device. The IoT device determines whether it needs to execute this configuration instruction through the individual ID in the individual configuration instruction. When its individual ID is the same as the individual ID in the individual configuration instruction, it needs to execute this individual configuration instruction and update its own configuration parameters by further parsing the configuration parameter name: configuration parameter value.

[0063] For example, in this example, the individual configuration command is SET 1 20 2 (Brightness: 10 Color Temperature: 3000). This indicates that the configuration command with command sequence number 1 configures two parameters for the IoT device with ID 20: brightness 10 and color temperature 3000. Thus, when the individual configuration command is broadcast, only the IoT device with ID 20 executes this individual configuration command, setting the brightness to 10 and the color temperature to 3000.

[0064] After executing an individual configuration command, an IoT device sends a response to the sender of the individual configuration command. The response format is: response code + sequence number + individual ID + status information. The response code is ACK, the sequence number is the sequence number of the received individual configuration command, which is used to distinguish the received individual configuration command, the individual ID is the unique identifier of each IoT device, and the status information indicates the specific status of the received individual configuration command.

[0065] For example, ACK 1 20 "OK" means that device No. 20 responded to command No. 1 and the status is received. "OK" can also be represented by 1.

[0066] In one implementation, step S200 in this embodiment includes the following steps:

[0067] Step S204: If the power carrier instruction is the group configuration instruction, obtaining the designated IoT device individual according to the individual ID in the group configuration instruction; wherein the group configuration instruction includes a group configuration instruction code, a serial number, a group number, a number of configured individuals, and the individual ID;

[0068] Step S205: assigning the designated IoT device to the IoT device group corresponding to the group number;

[0069] Step S206: Control the designated IoT device to issue a response instruction based on the serial number and the individual ID; wherein the response instruction includes a response instruction code, the serial number, the individual ID, and status information.

[0070] Specifically, the format of the group configuration instruction is group configuration instruction code + serial number + group number + number of configured individuals + multiple (individual IDs). The group configuration instruction code is GSET, which represents the instruction for setting the group, the serial number is a numerical identifier uniquely assigned to each power carrier instruction, which is used to distinguish which instruction it is, the individual ID is a unique identification code for each IoT device individual, the group number is a numerical identifier uniquely assigned to each IoT device group, the number of configured individuals is the number of IoT device individuals to be added to the group, and the individual ID is the unique identity identifier of the IoT device individual to be added to the specified group. Through the group configuration instruction, a single or multiple IoT device individuals can be added to the IoT device group to achieve unified control of the same group. If the number of configured individuals is multiple and is not equal to the total number of individual IDs in the group configuration instruction, the number of IoT device individuals that need to be configured is determined by the larger number between the number of configured individuals and the total number of actual individual IDs in the group configuration instruction. Each IoT device uses its individual ID in the group configuration instruction to determine whether it needs to execute this configuration instruction. When its individual ID is the same as the individual ID in the group configuration instruction, it needs to execute this individual configuration instruction, update its own group, and send a response instruction to the sender of the group configuration instruction.

[0071] For example, consider the group configuration instruction GSET 3 15 4 (1 3 5 10), which is a group configuration instruction with a sequence number of 3. This instruction places the four devices with ID numbers 1, 3, 5, and 10 into group 15. Thus, the four IoT devices with individual ID numbers 1, 3, 5, and 10 associate themselves with group 3. When the control terminal controls IoT device group 3, the four IoT devices with individual ID numbers 1, 3, 5, and 10 will respond simultaneously. For another example, the group configuration instruction GSET 4 -15 4 (1 3510), which is a group configuration instruction with a sequence number of 4, removes the four devices with individual ID numbers 1, 3, 5, and 10 from group 15.

[0072] In one implementation, step S200 in this embodiment includes the following steps:

[0073] Step S207: If the power carrier instruction is the scenario configuration instruction, obtaining the designated IoT device group according to the group number in the scenario configuration instruction; wherein the scenario configuration instruction includes a scenario configuration instruction code, a serial number, a scenario number, a number of configuration groups, the group number, and configuration parameters;

[0074] Step S208: grouping the designated IoT devices into the IoT device scene corresponding to the scene number;

[0075] Step S209: According to the IoT device grouping, obtain the IoT device individuals included in the IoT device grouping, and control the IoT device individuals to issue a response instruction; wherein the response instruction includes a response instruction code, the serial number, the individual ID of the IoT device individual, and status information.

[0076] Specifically, the format of the scene configuration instruction in this example is: scene configuration instruction code + serial number + scene number + number of configuration groups + multiple (group number: configuration parameters). The scene configuration instruction code is SSET, which represents the instruction for setting the scene, the serial number is a numerical identifier uniquely assigned to each power carrier instruction, which is used to distinguish which instruction it is, the scene number is a numerical identifier uniquely assigned to each IoT device group, the number of configuration groups is the number of IoT device groups to be added to the group, the group number is a numerical identifier uniquely assigned to each IoT device group, which is used to indicate which groups are to be added to the scene, and the configuration parameter is the configuration parameter name and configuration parameter value configured by the group number. Through the scene configuration instruction, a single or multiple IoT device groups can be added to the IoT device scene to achieve unified configuration and control of the same sub-scene. If the number of configuration groups is not equal to the total number of actual group numbers in the scene configuration instruction, the larger number between the number of configuration groups and the total number of actual group numbers in the group configuration instruction is used to determine the number of groups that the individual IoT device needs to configure. Each IoT device uses the group number in the scene configuration instruction to confirm whether it belongs to this group and needs to execute this configuration instruction. When its group number is the same as the group number in the group configuration instruction, it needs to execute this scene configuration instruction, update its own scene, and send a response instruction to the sender of the scene configuration instruction.

[0077] For example, if the scene configuration command is SSET 5 7 2 (6: "Light brightness: 0.8", 9: "Curtain up: 0.5"), the scene configuration command with sequence number 5 sets two parameters in scene number 7, namely, setting the light brightness in group 6 to 80% (0.8) and the curtain up in group 9 to 50%.

[0078] In one implementation, step S200 in this embodiment includes the following steps:

[0079] Step S210: If the power carrier instruction is the control instruction, then according to the control parameter name and control parameter value in the control instruction, the IoT device individual corresponding to the individual ID / group number / scene number is controlled to perform a control action and issue a response instruction; wherein the response instruction includes a response instruction code, a serial number, the individual ID and status information of the IoT device individual, and the control instruction includes a control instruction code, a serial number, the individual ID / group number / scene number, the number of control parameters, the control parameter name, and the control parameter value.

[0080] Specifically, the format of the control instruction is control instruction code + serial number + individual ID / group number / scene number + number of control parameters + multiple (control parameter name: control parameter value). Among them, when the control instruction is an individual control instruction, the control instruction code is CTRL, when the control instruction is a group control instruction, the control instruction code is GCTRL, when the control instruction is a scene control instruction, the control instruction code is SCTRL, the control parameter name is one of switch or adjustment value, and the control parameter value is: When the control parameter name is switch: it is a digital expression of one of on / off, such as 0 / 1, TRUE / FALSE, when the control parameter value is an adjustment value: the parameter value is the integer, floating point number, Boolean quantity or string to be set. The IoT device individual corresponding to the control individual ID / group number / scene number executes the control action and issues a response instruction.

[0081] For example, the individual control command CTRL 2 20 1 (Switch: 1) indicates that the setup command with command sequence number 2 sets an action for light ID 20, setting the switch value to 1 (on). If the switch value is set to 0, it is off. Another example is the group control command GCTRL 4 15 (Switch: 1) indicating that the group control command with command sequence number 4 turns on the devices in group 15. Another example is the scene control command SCTRL 7 5 1 indicating that the scene control command with sequence number 7 turns on scene 5 and sets the value to 1.

[0082] Step S300: Control the power carrier instruction to be retransmitted according to the response instruction.

[0083] Specifically, because all commands are broadcast over the power carrier line, all power carrier terminal devices determine whether the individual ID / group number / scene number in the command matches their previously configured one, and then execute the configuration and control actions. However, because power carriers are subject to significant interference from strong currents, some terminal devices may not receive the command. A response command can be used to determine whether the power carrier command has been received by the relevant device. If not, a retransmission mechanism is required to ensure delivery of the power carrier command.

[0084] In one implementation, step S300 in this embodiment includes the following steps:

[0085] Step S301: If the power carrier instruction is the individual configuration instruction or the control instruction containing the control individual ID, then according to the serial number and individual ID in the power carrier instruction, the corresponding individual ID of each serial number is obtained and stored in the system hash cache;

[0086] Step S302: If the power carrier instruction is the group configuration instruction, the scene configuration instruction, or the control instruction containing the group number / scene number, the individual ID is obtained according to the group number and the scene number, and then the corresponding individual ID for each sequence number is obtained according to the individual ID and the sequence number in the power carrier instruction and stored in the system hash cache;

[0087] Step S303: based on the serial number and individual ID in the response instruction, delete the responding individual ID of each serial number corresponding to the serial number and individual ID in the response instruction from the system hash cache;

[0088] Step S304: If the system Hash cache is not empty, reorganize and send the power carrier instructions corresponding to the serial numbers in the system Hash cache in batches according to a preset retransmission number threshold or retransmission time threshold, and obtain a response instruction corresponding to the serial number.

[0089] Specifically, the instruction sender maintains a system hash cache to record which terminal entities have received the instruction and which have not. Those that have received the instruction are deleted from the cache. For those that have not received the power carrier instruction, the instruction is resent using the same sequence number until a certain number of retransmissions or a certain time has passed. If all entities respond, the instruction is no longer resent.

[0090] In one implementation, the method of this embodiment further includes the following steps:

[0091] Step M100: If no response instruction corresponding to the sequence number is obtained after the retransmission number threshold or the retransmission time threshold is reached, the individual ID is set as abnormal, and the individual configuration instruction and the individual control instruction are no longer sent to the individual ID.

[0092] Specifically, if there is always no response from an individual, it means that there is a problem with the individual, and the individual ID status is recorded and the cache is cleared. This ensures that all equipment on site works reliably.

[0093] It should be noted that the individual configuration instructions, group configuration instructions and scene configuration instructions in this embodiment, the control instructions include individual control instructions, group control instructions and scene control instructions and the response instructions may also include an extended check code, version number or other attribute fields.
