Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to a message processing method, apparatus, user equipment, and storage medium. Background Art

[0002] Power Line Carrier Communication (PLC) is a technology that uses power lines for data transmission and communication. It uses power lines as the transmission medium and transmits data and signals by superimposing high-frequency signals on the power lines.

[0003] Currently, controlling PLC devices requires a PLC gateway to send messages to the PLC device, which then returns a message after executing an operation. This means that any message exchange involves two messages. Because PLC systems typically involve large-scale networking of dozens to hundreds of devices, the PLC system constantly exchanges a large number of messages while the PLC gateway performs batch control of devices and maintains device activity. This significantly increases the system's power consumption.

[0004] Therefore, how to reduce the number of messages when the PLC gateway interacts with PLC devices to reduce the power consumption of the PLC system is an urgent problem to be solved. Summary of the Invention

[0077] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0078] Currently, controlling PLC devices requires a PLC gateway to send messages to the PLC device, which then returns a message after executing an operation. This means that any message exchange involves two messages. Because PLC systems typically involve large-scale networking of dozens to hundreds of devices, the PLC system constantly exchanges a large number of messages while the PLC gateway performs batch control of devices and maintains device activity. This significantly increases the system's power consumption.

[0079] See Figure 1 , Figure 1 FIG is a schematic flow chart of a method for message processing according to an embodiment of the present disclosure. Figure 1 As shown, the message processing method may include the following steps:

[0080] In step 102, the power line carrier communication PLC gateway obtains an operation instruction for at least one PLC device sent by a user.

[0081] In step 104, a PLC link message including the operation instruction is generated, and the device identification of the at least one PLC device is filled into the PLC link message.

[0082] In step 106, the PLC link message is broadcasted to enable the PLC device corresponding to at least one device identifier in the PLC link message to execute the operation instruction contained in the PLC link message and return a response message containing the execution result corresponding to the operation instruction.

[0083] In practical applications, there are two methods for controlling PLC devices. The first method involves the PLC gateway sending messages sequentially based on the address of each PLC device. Upon receiving the message, the PLC device executes the instructions contained in the message and then returns a message. This method generates two messages for each message exchange, resulting in a large number of messages between the PLC gateway and the PLC device, leading to higher power consumption in the PLC system.

[0084] The second method involves the PLC gateway broadcasting messages, requiring all PLC devices to respond after receiving them. This method requires PLC devices that don't need to execute operational instructions to respond, increasing the number of messages exchanged between the PLC gateway and PLC devices and leading to higher power consumption in the PLC system.

[0085] In one possible implementation, a power line carrier communication PLC gateway obtains an operation instruction sent by a user for at least one PLC device, wherein the operation instruction includes: single-point control instruction, batch control instruction, configuration instruction, keep-alive instruction, query instruction, etc.

[0086] Then, a PLC link message containing an operation instruction is generated according to the PLC link message format, and the device identification of at least one PLC device is filled into a designated position in the PLC link message.

[0087] Next, the PLC link message is broadcasted so that the PLC device corresponding to at least one device identifier in the PLC link message responds to the received PLC link message, executes the operation instruction contained in the PLC link message, and returns a response message containing the execution result corresponding to the operation instruction.

[0088] It can be seen from the above embodiments that by filling the device identification of at least one PLC device into the specified position in the PLC link message, the PLC device that does not need to execute the operation instruction no longer needs to return the message, thereby reducing the number of messages when the PLC gateway interacts with the PLC device, and further reducing the power consumption of the PLC system.

[0089] It should be noted that, in one possible implementation, the application scenario of the message processing method is a whole-house intelligent control scenario, which requires the control of PLC devices throughout the house. PLC devices include: PLC lights, curtains, air conditioners, sensors, etc. For example, if the sensor detects that there is someone in the house and the current time is the set time, it will trigger the set mode, adjust each PLC light to the set color temperature and set brightness, and control the curtains, etc. Of course, the application scenario of the message processing method can also be other application scenarios. This specification does not limit the application scenario of the message processing method.

[0090] See Figure 2 , Figure 2 is based on Figure 1 A schematic flow chart of another message processing method based on the embodiment shown. Figure 2 As shown, the method may further include:

[0091] In step 202, if the operation instruction is a single-point control instruction, it is determined whether the target device state is the same as the current device state of the target PLC device cached in the PLC gateway.

[0092] In step 204, if yes, the current device status corresponding to the target PLC device is returned.

[0093] In step 206, if not, a PLC link message containing the single-point control instruction is generated, and the PLC link message containing the single-point control instruction is sent to the target PLC device, so that the target PLC device executes the single-point control instruction and returns a response message containing the current device status of the target PLC device.

[0094] In actual applications, when a PLC device is already powered on and the user still selects the power-on command, the PLC gateway will still send a message to the PLC device, prompting the PLC device to execute the power-on command and then return the message. This increases the number of meaningless messages sent between the PLC gateway and the PLC device, further increasing the power consumption of the PLC system.

[0095] In one possible implementation, the operation instruction includes a single-point control instruction, where the single-point control instruction includes a target device state corresponding to a target PLC device. If the operation instruction is a single-point control instruction, a determination is made as to whether the target device state is the same as a current device state of the target PLC device cached in the PLC gateway.

[0096] If yes, return the current device status corresponding to the target PLC device.

[0097] If not, generate a PLC link message containing a single-point control instruction according to the PLC link message format, and send the PLC link message containing the single-point control instruction to the target PLC device, so that the target PLC device executes the single-point control instruction and returns a response message containing the current device status of the target PLC device.

[0098] See Figure 3 , Figure 3 It is a schematic diagram showing a message format of a single-point control instruction according to an embodiment of the present disclosure.

[0099] exist Figure 3In the single-point control instruction message format, the message format includes: header, unicast address, gateway address, length, message data, and message tail. The message data can be filled with the control instruction to be executed by the PLC device in the single-point control instruction.

[0100] It can be seen from the above embodiments that when the PLC device state in the control instruction selected by the user is the same as the current device state of the target PLC device, the PLC gateway can directly return the current device state of the target PLC device without sending a message to the target PLC device, thereby reducing the number of messages when the PLC gateway interacts with the PLC device, and further reducing the power consumption of the PLC system.

[0101] See Figure 4 , Figure 4 is based on Figure 1 A schematic flow chart of another message processing method based on the embodiment shown. Figure 4 As shown, the method may include:

[0102] In step 402, if the operation instruction in the PLC link message is a batch control instruction, the PLC link message is broadcast so that the at least one PLC device queries its own device identification from the PLC link message, and determines whether its own device identification exists in the PLC link message. If so, the batch control instruction contained in the PLC link message is executed, and a response message containing the current device status of the at least one PLC device is returned.

[0103] In step 404, if the operation instruction in the PLC link message is a configuration instruction, the PLC link message is broadcast so that the at least one PLC device queries its own device identification from the PLC link message, determines whether its own device identification exists in the PLC link message, and if so, executes the configuration instruction contained in the PLC link message, and returns a response message containing the current device configuration of the at least one PLC device.

[0104] In step 406, if the operation instruction in the PLC link message is a keep-alive instruction, the PLC link message is broadcast so that the at least one PLC device queries its own device identification from the PLC link message, and determines whether its own device identification exists in the PLC link message. If so, the keep-alive instruction contained in the PLC link message is executed, and a response message containing the operating status of the at least one PLC device is returned.

[0105] In actual applications, the PLC gateway can broadcast messages, and all PLC devices must return messages after receiving them. This method requires PLC devices that do not need to execute operation instructions to return messages, increasing the number of messages when the PLC gateway interacts with PLC devices, resulting in higher power consumption of the PLC system.

[0106] In a possible implementation, the type of the operation instruction is a batch control instruction, and the batch control instruction mentioned here includes a target device state corresponding to at least one PLC device.

[0107] If the operation instruction is a batch control instruction, a PLC link message containing the batch control instruction is generated according to the PLC link message format, and the device identification of at least one PLC device is filled in the specified position in the PLC link message.

[0108] Then, the PLC link message is broadcasted so that at least one PLC device queries its own device identification from the PLC link message, determines whether its own device identification exists in the PLC link message, and if so, executes the batch control instructions contained in the PLC link message in response to the received PLC link message, and returns a response message containing the current device status of at least one PLC device.

[0109] See Figure 5 , Figure 5 It is a schematic diagram showing a message format of a batch control instruction according to an embodiment of the present disclosure.

[0110] exist Figure 5 The message format of the batch control instruction includes: a header, a broadcast address, a gateway address, a length, message data, and a trailer. The message data can be filled with the device identification of at least one PLC device in the batch control instruction and the control instruction to be executed by at least one PLC device.

[0111] As can be seen from the above embodiment, the PLC gateway can insert the device identifier of the PLC device that needs to execute the control instruction into the message. When the PLC device finds the control instruction it needs to execute from the message, it executes the control instruction contained in the message. This reduces the number of messages exchanged between the PLC gateway and the PLC device, thereby reducing the power consumption of the PLC system.

[0112] In actual applications, the PLC gateway can broadcast messages, and all PLC devices must return messages after receiving them. This method requires PLC devices that do not need to execute operation instructions to return messages, increasing the number of messages when the PLC gateway interacts with PLC devices, resulting in higher power consumption of the PLC system.

[0113] In a possible implementation, the type of the operation instruction is a configuration instruction, and the configuration instruction mentioned here includes a target device configuration corresponding to the at least one PLC device.

[0114] If the operation instruction is a configuration instruction, a PLC link message containing the configuration instruction is generated according to the PLC link message format, and the device identification of at least one PLC device is filled in a designated position in the PLC link message.

[0115] Then, a PLC link message is broadcasted to enable at least one PLC device to query its own device identification from the PLC link message, and determine whether its own device identification exists in the PLC link message. If so, in response to the received PLC link message, the configuration instructions contained in the PLC link message are executed, and a response message containing the current device configuration of at least one PLC device is returned.

[0116] See Figure 6 , Figure 6 It is a schematic diagram showing a message format of a configuration instruction according to an embodiment of the present disclosure.

[0117] exist Figure 6 The message format of the configuration instruction includes: a header, a broadcast address, a gateway address, a length, message data, and a footer. The message data can be filled with the device identification of at least one PLC device and the configuration instruction to be executed by at least one PLC device.

[0118] As can be seen from the above embodiment, the PLC gateway can insert the device identifier of the PLC device that needs to execute the configuration instruction into the message. This allows the PLC device to execute the configuration instruction contained in the message when it finds that it needs to execute the configuration instruction from the message. This reduces the number of messages when the PLC gateway interacts with the PLC device, thereby reducing the power consumption of the PLC system.

[0119] In actual applications, due to the high-voltage nature of PLC devices, PLC devices are connected to the network along with the power supply and usually do not experience power outages. In this case, the PLC devices need to regularly report keep-alive messages. If the period for regularly reporting keep-alive messages by the PLC devices needs to be adjusted, additional configuration messages need to be sent or the period for regularly reporting keep-alive messages by updating the firmware needs to be adjusted, which will further increase the power consumption of the PLC system.

[0120] In a possible implementation, the type of the operation instruction is a keep-alive instruction, and the keep-alive instruction mentioned here is used to confirm whether the device is operating normally.

[0121] If the operation instruction is a keep-alive instruction, a PLC link message including the keep-alive instruction is generated according to the PLC link message format, and the device identification of at least one PLC device is filled into a designated position in the PLC link message.

[0122] Then, a PLC link message is broadcasted to enable at least one PLC device to query its own device identification from the PLC link message, and determine whether its own device identification exists in the PLC link message. If so, in response to the received PLC link message, the keep-alive instruction contained in the PLC link message is executed, and a response message containing the operating status of at least one PLC device is returned.

[0123] See Figure 7 , Figure 7 This is a schematic diagram showing a message format of a keep-alive instruction according to an embodiment of the present disclosure.

[0124] exist Figure 7 The message format of the keep-alive instruction includes: a header, a broadcast address, a gateway address, a length, message data, and a footer. The message data can be filled with the device identification of at least one PLC device and the keep-alive instruction to be executed by at least one PLC device.

[0125] Among them, the PLC gateway can manage the keep-alive cycles of different PLC devices. The PLC device determines whether to send a keep-alive instruction to the PLC device, and the PLC device does not need to actively report keep-alive information.

[0126] As can be seen from the above embodiment, the PLC gateway can manage the keepalive periods of different PLC devices. The PLC devices determine whether to send keepalive instructions to them, eliminating the need for the PLC devices to proactively report keepalive information. This not only reduces the number of keepalive messages sent by PLC devices, but also reduces the power consumption of the PLC devices, thereby reducing the power consumption of the PLC system.

[0127] It should be noted that the response message returned by the PLC device can update the keep-alive period of the PLC device, thereby further reducing the number of keep-alive messages sent by the PLC device.

[0128] See Figure 8 , Figure 8 is based on Figure 1 A schematic flow chart of another message processing method based on the embodiment shown. Figure 8 As shown, the method may further include:

[0129] In step 802, a status score of the at least one PLC device during operation is calculated according to a historical response message of the at least one PLC device corresponding to the keep-alive instruction.

[0130] In step 804, a keep-alive period corresponding to the at least one PLC device is determined according to the status score of the at least one PLC device during operation.

[0131] In step 806 , it is determined whether the keep-alive period of the at least one PLC device has expired.

[0132] In step 808, if yes, a PLC link message including the keep-alive instruction is generated.

[0133] In a possible implementation, a status score of the at least one PLC device during operation is calculated according to historical response messages corresponding to keep-alive instructions of the at least one PLC device.

[0134] Then, a keep-alive period corresponding to the at least one PLC device is determined based on the state score of the at least one PLC device during operation. For example, the more stable the PLC device is, the higher the state score is, and the longer the keep-alive period corresponding to the PLC device is.

[0135] Next, it is determined whether a keep-alive period of at least one PLC device has expired.

[0136] If yes, generate a PLC link message containing a keep-alive instruction according to the PLC link message format.

[0137] It can be seen from the above embodiments that when the operating state of the PLC device is relatively stable, the keep-alive period of the PLC device can be appropriately extended, thereby further reducing the number of keep-alive messages sent by the PLC device and further reducing the power consumption of the PLC system.

[0138] See Figure 9 , Figure 9 is based on Figure 1 A schematic flow chart of another message processing method based on the embodiment shown. Figure 9 As shown, the method may further include:

[0139] In step 902, if the operation instruction is a query instruction, it is determined whether the device attributes required to be queried for the target PLC device are cached in the PLC gateway.

[0140] In step 904, if yes, the device properties of the target PLC device are returned.

[0141] In step 906, if not, a PLC link message containing the query instruction is generated, and the PLC link message containing the query instruction is sent to the target PLC device, so that the target PLC device fills the device attributes required to be queried by the target PLC device into the specified position in the response message corresponding to the keep-alive instruction, and returns the response message corresponding to the keep-alive instruction.

[0142] In real-world applications, when a user needs to query the device properties of a PLC device, the PLC gateway must send a message to the PLC device, which then responds with a message containing the device properties. This increases the number of messages exchanged between the PLC gateway and the PLC device, further increasing the power consumption of the PLC system.

[0143] In a possible implementation, the type of the operation instruction is a query instruction, and the configuration instruction mentioned here includes device properties that need to be queried for the target PLC device.

[0144] If the operation instruction is a query instruction, it is determined whether the device attributes of the target PLC device to be queried are cached in the PLC gateway.

[0145] If yes, return the device properties of the target PLC device.

[0146] If not, generate a PLC link message containing a query instruction according to the PLC link message format, and send the PLC link message containing the query instruction to the target PLC device, so that the target PLC device fills the device attributes required to be queried by the target PLC device into the specified position in the response message corresponding to the keep-alive instruction, and returns the response message corresponding to the keep-alive instruction.

[0147] See Figure 10 , Figure 10 It is a schematic diagram showing another message format of a keep-alive instruction according to an embodiment of the present disclosure.

[0148] exist Figure 10 The keep-alive instruction message format includes a header, a broadcast address, a gateway address, a length, message data, and a trailer. The message data may include the device identifier of at least one PLC device, the keep-alive instruction to be executed by at least one PLC device, and the device attributes of at least one PLC device.

[0149] It can be seen from the above embodiments that when the device properties of the PLC device in the query instruction are cached in the PLC gateway, the PLC gateway can directly return the current device properties of the target PLC device without sending a PLC link message to the target PLC device, so as to reduce the number of messages when the PLC gateway interacts with the PLC device, and thus the power consumption of the PLC system.

[0150] If the PLC gateway doesn't cache the device attributes of the PLC device in the query command, the target PLC device can fill the device attributes it needs to query into the specified location in the response message corresponding to the keep-alive command and return the response message corresponding to the keep-alive command, eliminating the need to return a message for the query command. This further reduces the number of messages exchanged between the PLC gateway and the PLC device, further reducing the power consumption of the PLC system.

[0151] See Figure 11 , Figure 11 It is a schematic diagram showing a message processing process according to an embodiment of the present disclosure.

[0152] exist Figure 11 In Figure 3 For example, if the operation instruction includes a single-point control instruction, the system receives the single-point control instruction sent by the cloud platform and determines whether the target device status in control instructions 1 and 2 is the same as the current device status of PLC device 1 cached in the PLC gateway. If so, the system returns the current device status of PLC device 1. If not, the system sends a PLC link message containing control instructions 1 and 2 to PLC device 1, causing PLC device 1 to execute control instructions 1 and 2 and return a response message containing the current device status of PLC device 1.

[0153] by Figure 5 For example, if the operation instruction is a batch control instruction, the batch control instruction sent by the cloud platform is received, and the device identifiers of PLC device 1 and PLC device 2 are filled in the position where the control instruction 1 in the PLC link message is located, and the device identifier of PLC device 3 is filled in the position where the control instruction 2 in the PLC link message is located.

[0154] Then, the PLC link message is broadcasted to enable PLC device 1 and PLC device 2 to execute control instruction 1 and return a response message containing the current device status, and PLC device 3 to execute control instruction 2 and return a response message containing the current device status.

[0155] by Figure 6 For example, if the operation instruction is a configuration instruction, the configuration instruction sent by the cloud platform is received, and the device identifiers of PLC device 1 and PLC device 2 are filled in the position where configuration instruction 1 is located in the PLC link message, and the device identifier of PLC device 3 is filled in the position where configuration instruction 2 is located in the PLC link message.

[0156] Then, the PLC link message is broadcasted to enable PLC device 1 and PLC device 2 to execute configuration instruction 1 and return a response message containing the current device configuration, and PLC device 3 to execute configuration instruction 2 and return a response message containing the current device configuration.

[0157] by Figure 7 For example, if the operation instruction is a keep-alive instruction, the device identifiers of PLC device 1, PLC device 2, and PLC device 3 are filled in the position where the keep-alive instruction is located in the PLC link message.

[0158] Then, a PLC link message is broadcasted to enable PLC device 1, PLC device 2, and PLC device 3 to execute a keep-alive instruction and return a response message containing the operating status.

[0159] by Figure 10 For example, if the operation instruction is a query instruction, the query instruction sent by the cloud platform is received, and it is determined whether the device attributes to be queried in the query instruction 1 are the same as the current device status of the PLC device 1 cached in the PLC gateway.

[0160] If yes, return the device properties of PLC device 1.

[0161] If not, the PLC link message containing query instruction 1 is sent to PLC device 1, so that PLC device 1 fills the device attributes required by PLC device 1 into the specified position in the response message corresponding to the keep-alive instruction, and returns the response message corresponding to the keep-alive instruction.
