Description

TECHNICAL FIELD

[0001] The present application relates to the field of device control and the field of digital twinning, and in particular to a device control method and device, apparatus and storage medium. BACKGROUND

[0002] Digital twinning technology, as a technology for realizing the interactive fusion of the physical world and the information world by constructing a digital mirror image of a physical entity, has been widely applied to scenarios such as device monitoring, simulation, control and predictive maintenance.

[0003] At present, the way to realize device control is often to issue a state switching instruction to a digital twin model corresponding to a target physical device, generate a device control strategy based on the instruction by the digital twin model, and drive the target physical device to perform a state switching operation according to the device control strategy.

[0004] However, since the existing technology has strong dependence on the accuracy and timeliness of the state switching instruction, if there is a parameter deviation or transmission delay in the state switching instruction, it will directly lead to an error in the generation of the device control strategy, or the device state switching action cannot be performed on time. SUMMARY

[0005] The present application provides a device control method, apparatus, device and storage medium, which can realize efficient and accurate control of the target physical device to switch states.

[0006] In a first aspect, an embodiment of the present application provides a device control method, comprising:

[0007] obtaining a target physical device and constructing a digital twin model corresponding to the target physical device;

[0008] The digital twin model includes a state model, and the state model includes a current state, a target state and at least one state transition condition corresponding to the target physical device.

[0009] According to the comparison result of the current state and the target state, and / or the state transition condition, it is determined whether the target physical device needs to be controlled to switch states;

[0010] When it is determined that the target physical device needs to be controlled to switch states, the target state transition condition satisfied by the target physical device is obtained, and a device control strategy matched with the target state transition condition is determined;

[0011] A device control instruction corresponding to the device control strategy is generated, and the device control instruction is sent to the target physical device to control the target physical device to execute the device control instruction.

[0012] In a second aspect, an embodiment of the present application further provides a device control apparatus, comprising:

[0013] The twin model building module is used to acquire the target physical device and build a digital twin model corresponding to the target physical device.

[0014] The digital twin model includes a state model, which includes the current state of the target physical device, the target state, and at least one state transition condition.

[0015] The state transition judgment module is used to determine whether it is necessary to control the target physical device to perform a state transition based on the comparison result between the current state and the target state, and / or the state transition conditions.

[0016] The control strategy generation module is used to obtain the target state transition conditions that the target physical device needs to meet when it is determined that the target physical device needs to switch states, and to determine the device control strategy that matches the target state transition conditions.

[0017] The device control module is used to generate device control instructions corresponding to the device control strategy and send the device control instructions to the target physical device to control the target physical device to execute the device control instructions.

[0018] Thirdly, embodiments of the present invention also provide an electronic device, the electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores a computer program executable by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to execute the device control method provided in any embodiment of the present invention.

[0019] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the device control method provided in any embodiment of the present invention.

[0020] The technical solution of this invention solves the problem of existing technologies that are highly dependent on the accuracy and timeliness of state switching instructions. This is because existing technologies, when there are parameter deviations or transmission delays in the state switching instructions, are prone to errors in generating the device control strategy or failing to execute the device state switching action on time. The invention achieves efficient and accurate control of the target physical device for state switching. This is achieved by constructing a digital twin model corresponding to the target physical device; determining whether state switching needs to be controlled based on the state model in the digital twin model; when state switching instructions have parameter deviations or transmission delays, the target physical device is controlled for state switching.

[0029] Example 1

[0030] Figure 1 This is a flowchart of a device control method according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of state control of target physical devices based on digital twin technology. The method can be executed by a device control device, which can be implemented in hardware and / or software and can be configured in an electronic device such as a computer.

[0031] like Figure 1 As shown, this embodiment discloses a device control method, including:

[0032] S110. Obtain the target physical device and construct a digital twin model corresponding to the target physical device; wherein, the digital twin model includes a state model, which includes the current state of the target physical device, the target state, and at least one state transition condition.

[0033] In this embodiment, the target physical device can be understood as a device whose current state needs to be continuously monitored to determine if it is in the target state, and which triggers a state switch when its current state is not in the target state, such as a water pump, a fan, and a sensor. The current state can be understood as the actual state of the target physical device. The target state can be understood as the state that the user expects the target physical device to maintain. The state transition condition can be understood as the precondition that must be met to control the target physical device to switch from its current state to the target state. There can be various state transition conditions, such as the target physical device's current state meeting predefined state change requirements, or related devices being in a controllable state. It is worth noting that the state change requirement can be a boundary requirement within the target state, or a predefined change requirement unrelated to the target state; this embodiment does not impose any limitations on this.

[0034] In this step, specifically, a state model corresponding to the target physical device can be configured based on the current state, the target state, and at least one state transition condition. Then, digital twin technology can be used to construct a digital twin model corresponding to the target physical device based on its geometric attributes, physical attributes, and state model.

[0035] S120. Based on the comparison between the current state and the target state, and / or the state transition conditions, determine whether it is necessary to control the target physical device to switch states.

[0036] Specifically, based on the comparison between the current state and the target state, determining whether it is necessary to control the target physical device to switch states can include: if the current state and the target state are the same, determining that it is necessary to control the target physical device to switch states; if the current state and the target state are different, determining that it is not necessary to control the target physical device to switch states.

[0037] Based on the comparison between the current state and the target state, and the state transition conditions, determine whether it is necessary to control the target physical device to switch states. This can include: if the current state and the target state are the same, determining whether it is necessary to control the target physical device to switch states; if the current state and the target state are different, determining whether it is necessary to control the target physical device to switch states based on the state transition conditions.

[0038] Based on the state transition conditions, determining whether to control the target physical device to switch states can include: if the target physical device meets all state transition conditions, then controlling the target physical device to switch states is required; if the target physical device does not meet all state transition conditions, then controlling the target physical device to switch states is not required.

[0039] Optionally, before determining whether it is necessary to control the target physical device to switch states based on the comparison results between the current state and the target state, and / or the state transition conditions, the method further includes: displaying a state model configuration interface to the user in response to the state model configuration operation triggered by the user for the target physical device; and generating a state model corresponding to the digital twin model in response to the target state and state transition conditions configured by the user on the state model configuration interface.

[0040] Specifically, upon receiving the target state input by the user on the state model configuration interface, and at least one state transition condition corresponding to the target state, a state model corresponding to the digital twin model can be generated based on the target state and the corresponding state transition condition.

[0041] The advantage of this setup is that, compared to generating a state model based on application code, the technical solution in this embodiment obtains the state model based on the state model configuration interface. This allows for modification of the target state and state transition conditions without modifying the application code, thereby improving the flexibility and maintainability of state switching control over the target physical device.

[0042] S130. When it is determined that the target physical device needs to be controlled to switch states, the target state transition conditions satisfied by the target physical device are obtained, and the device control strategy matching the target state transition conditions is determined.

[0043] In this embodiment, the target state transition condition can be understood as the state transition condition that has been triggered by the target physical device. The device control strategy can be used to control the target physical device to switch from its current state to the target state.

[0044] In this step, specifically, if it is determined whether the target physical device needs to switch states based solely on the comparison between the current state and the target state, the target state transition conditions that the target physical device must meet can be determined based on the current environmental data and / or current operating data of the target physical device.

[0045] If it is determined whether the target physical device needs to be controlled to switch states based on the state transition conditions, the current state, and the target state, or only based on the state transition conditions, the target state transition conditions already determined in S120 can be directly obtained.

[0046] After obtaining the target state transition conditions satisfied by the target physical device, a device control strategy matching the target state transition conditions can be generated using a pre-built control strategy generation model, based on the current state, target state, and target state transition conditions. Alternatively, a predefined control strategy table can be queried based on the target state transition conditions to obtain the device control strategy matching the target state transition conditions. The control strategy table contains multiple sets of correspondences between state transition conditions and device control strategies.

[0047] S140. Generate device control instructions corresponding to the device control strategy and send the device control instructions to the target physical device to control the target physical device to execute the device control instructions.

[0048] In this step, specifically, device control commands corresponding to the device control strategy can be generated based on the target communication protocol followed by the target physical device. Alternatively, the information forwarding device corresponding to the target physical device can be obtained, and device control commands corresponding to the device control strategy can be generated based on the information communication protocol followed by the information forwarding device.

[0049] The technical solution of this embodiment obtains the target physical device and constructs a digital twin model corresponding to the target physical device. The digital twin model includes a state model, which includes the current state of the target physical device, a target state, and at least one state transition condition. Based on the comparison between the current state and the target state, and / or the state transition condition, it is determined whether the target physical device needs to be controlled for a state switch. When it is determined that the target physical device needs to be controlled for a state switch, the target state transition condition satisfied by the target physical device is obtained, and a device control strategy matching the target state transition condition is determined. A device control command corresponding to the device control strategy is generated, and the device control command is sent to the target physical device to control the target physical device to execute the device control command. This technical means solves the problem of existing technologies that are highly dependent on the accuracy and timeliness of state switching commands. When there are parameter deviations or transmission delays in the state switching commands, it is easy to cause errors in the generation of device control strategies or failure to execute device state switching actions on time. This can achieve efficient and accurate control of the target physical device for state switching.

[0050] Example 2

[0051] Figure 2 This is a flowchart of another device control method provided according to Embodiment 2 of the present invention. This embodiment is a further optimization and extension based on the above embodiments, and can be combined with various optional technical solutions in the above embodiments.

[0052] like Figure 2 As shown, this embodiment discloses a device control method, including:

[0053] S210. Obtain the target physical device and construct a digital twin model corresponding to the target physical device; wherein, the digital twin model includes a state model, which includes the current state of the target physical device, the target state, and at least one state transition condition.

[0054] Taking a water tank as an example, the target state of the water tank can be configured as follows: the current liquid level is neither higher than a preset maximum level nor lower than a preset minimum level. Two state transition conditions can be configured: the current liquid level is lower than the preset minimum level, and the water pump is in a controllable state. Then, the current liquid level of the water tank can be obtained, and based on the current liquid level, the target state, and the state transition conditions, a state model corresponding to the water tank can be generated. Finally, a digital twin model corresponding to the water tank can be constructed based on the state model.

[0055] S220. Determine whether the current state is consistent with the target state. If yes, execute S230; otherwise, execute S240.

[0056] Continuing with the previous example, we can determine whether the current liquid level in the water tank is higher than the preset maximum liquid level and lower than the preset minimum liquid level. If the current liquid level in the water tank is neither higher than the preset maximum liquid level nor lower than the preset minimum liquid level, it is determined that there is no need to control the target physical device to switch states, and the system continuously monitors whether the current liquid level in the water tank has reached the target state. If the current liquid level in the water tank is higher than the preset maximum liquid level or lower than the preset minimum liquid level, it is determined whether to control the target physical device to switch states based on the state transition conditions.

[0057] S230. Determine that it is not necessary to control the target physical device to switch states, and return to perform the operation of judging whether the current state is consistent with the target state, until the predefined loop termination condition is reached.

[0058] In this embodiment, there can be multiple loop termination conditions, such as the user triggering a loop termination operation, the loop monitoring duration exceeding a predefined first duration threshold, or the loop monitoring count reaching a predefined first count threshold.

[0059] The above settings allow for continuous monitoring of whether the current state of the target physical device matches the target state, thus ensuring the operational reliability of the target physical device.

[0060] S240. Based on the state transition conditions, determine whether it is necessary to control the target physical device to switch states.

[0061] In this step, specifically, it is determined whether the target physical device needs to be controlled to switch states, based on whether it meets all state transition conditions. Alternatively, it can be determined whether the target physical device needs to be controlled to switch states based on the type of state transition conditions it meets.

[0062] Optionally, depending on whether the target physical device meets all state transition conditions, it is determined whether the target physical device needs to be controlled to switch states, including: determining whether the target physical device meets all state transition conditions based on the target physical device's current environmental data and / or current operating data; if the target physical device meets all state transition conditions, it is determined that the target physical device needs to be controlled to switch states; if the target physical device does not meet all state transition conditions, it is determined that the target physical device does not need to be controlled to switch states.

[0063] The current environmental data reflects the connection status between the target physical device and associated devices, which can be either connected or disconnected. The current operational data refers to the operational data of the target physical device itself.

[0064] Specifically, if the state transition condition is that the current state of the target physical device meets predefined state change requirements, then based on the current operating data of the target physical device, it can be determined whether the target physical device meets all state transition conditions. If the state transition condition is that the associated devices related to the target physical device are in a controllable state, then based on the current environmental data of the target physical device, it can be determined whether the target physical device meets all state transition conditions. If the state transition conditions include both the current state of the target physical device meeting predefined state change requirements and the associated devices related to the target physical device being in a controllable state, then based on the current environmental data and current operating data of the target physical device, it can be determined whether the target physical device meets all state transition conditions.

[0065] Taking the conditions for state transition, including the target physical device's current state meeting predefined state change requirements and related equipment being in a controllable state, as an example, if based on the current environmental and operational data of the water tank, it is determined that the current liquid level in the tank is below the preset minimum level, and the water replenishment pump is in a controllable state, then it can be determined that the target physical device needs to be controlled to switch states. If, based on the current environmental and operational data of the water tank, it is determined that the current liquid level in the tank is above the preset minimum level, or the water replenishment pump is out of control, then it can be determined that the target physical device does not need to be controlled to switch states.

[0066] The advantage of this setting is that by comparing the current state with the target state and the state transition conditions, it can be determined whether the target physical device needs to be controlled to switch states. This allows for a more accurate determination of whether the target physical device needs to be controlled to switch states, thereby improving the reliability of the state transition results and increasing user satisfaction.

[0067] S250. When it is determined that the target physical device needs to be controlled to switch states, the target state transition conditions satisfied by the target physical device are obtained from all the state transition conditions in the state model, and the device control strategy that matches the target state transition conditions is determined.

[0068] For example, when the target state transition condition is that the current liquid level is lower than the preset minimum liquid level and the water replenishment pump is in a controllable state, it can be considered that the water tank has consumed too much water and has not been replenished in time. At this time, it can be determined that the equipment control strategy is to turn on the water replenishment pump to replenish the water tank.

[0069] S260. Obtain the target communication protocol followed by the target physical device, and generate device control instructions corresponding to the device control strategy based on the target communication protocol.

[0070] In this embodiment, the target communication protocol can be of various types, such as the OPC Unified Architecture (OPC UA) protocol, the industrial fieldbus protocol, and the Message Queuing Telemetry Transport (MQTT) protocol.

[0071] S270. Send the device control command to the target physical device to control the target physical device to execute the device control command.

[0072] Optionally, after sending the device control command to the target physical device, the method further includes: obtaining the actual state of the target physical device after executing the device control command; updating the current state recorded in the state model according to the actual state, and returning the operation to determine whether it is necessary to control the target physical device to perform a state switching based on the comparison result between the current state and the target state, and / or the state transition condition, until a predefined loop termination condition is reached.

[0073] Specifically, the current state recorded in the state model can be directly updated to the actual state. Alternatively, the current state recorded in the state model can be updated based on the actual state, the target state, and the comparison result.

[0074] Furthermore, updating the current state recorded in the state model based on the actual state, the target state, and the comparison result may include: determining whether the current state is consistent with the target state; if so, updating the current state recorded in the state model to the actual state; if not, returning to the operation of sending the device control command to the target physical device until the actual state is consistent with the target state, and then updating the current state recorded in the state model to the actual state.

[0075] There are several possible conditions for terminating the status update, such as the number of times device control commands are sent to the target physical device reaches a predefined second threshold, or the duration of the process of updating the current status exceeds a second duration threshold.

[0076] Specifically, when the current state and the target state are inconsistent, it can be determined whether a predefined state update termination condition has been met. If the predefined state update termination condition has not been met, the operation of sending device control commands to the target physical device is returned until the actual state matches the target state. Then, the current state recorded in the state model is updated to the actual state, or the device control flow is terminated and a fault message for the target physical device is sent to the user when the predefined state update termination condition is met.

[0077] The advantage of this setup is that by introducing a closed-loop feedback mechanism, it can ensure that the current state of the device recorded in the digital twin model is always highly consistent with the actual state of the target physical device, thus providing a reliable data foundation for subsequent simulation of various device control operations.

[0078] The technical solution in this embodiment determines whether a state switch of the target physical device is needed by comparing the current state with the target state and considering the state transition conditions. This allows for a more accurate determination of whether a state switch is necessary, thereby improving the reliability of the state switch results and enhancing user satisfaction. Secondly, by introducing a closed-loop feedback mechanism, it ensures that the current state of the device recorded in the digital twin model remains highly consistent with the actual state of the target physical device, thus providing a reliable data foundation for subsequent simulations of various device control operations.

[0079] To illustrate the device control method and its effects in this invention in detail, the following description uses a device control system that applies the device control method of this invention as an example: The device control system includes a control logic editing tool, a rule engine, and a control action executor. The rule engine is communicatively connected to both the control logic editing tool and the control action executor.

[0080] Specifically, the control logic editing tool can respond to user-triggered state model configuration operations for target physical devices, displaying a state model configuration interface to the user, and generating a state model corresponding to the digital twin model in response to the target state and state transition conditions configured by the user on the state model configuration interface. Furthermore, the control logic editing tool can also encapsulate the computational logic of the state model into a standardized interface, enabling the rule engine to invoke the current state, target state, and state transition conditions in the state model. Based on the model encapsulation function of the control logic editing tool, the rule engine can determine whether it is necessary to control the target physical device to switch states based on the comparison results between the current state and the target state, and / or the state transition conditions.

[0081] Furthermore, the rule engine can also be used to, when it is determined that a state transition of the target physical device needs to be controlled, obtain the target state transition condition satisfied by the target physical device from all state transition conditions in the state model, and determine the device control strategy matching the target state transition condition; when it is determined that a state transition of the target physical device does not need to be controlled, it returns to the operation of determining whether a state transition of the target physical device needs to be controlled based on the comparison result between the current state and the target state, and / or the state transition condition, until a predefined loop termination condition is reached. The control action executor can be used to receive the device control strategy sent by the rule engine, generate device control instructions corresponding to the device control strategy, and send the device control instructions to the target physical device. In addition, the control action executor can also be used to obtain the actual state of the target physical device after executing the device control instructions; update the current state recorded in the state model according to the actual state, and return to the operation of determining whether a state transition of the target physical device needs to be controlled based on the comparison result between the current state and the target state, and / or the state transition condition, until a predefined loop termination condition is reached.

[0082] The advantage of this setup is that, compared to existing technologies that directly write device control strategy generation methods through application code, the technical solution of this invention, by setting a rule engine in the device control system, can integrate more complex algorithms, such as optimization algorithms and deep learning models, to generate the optimal device control strategy, thereby reducing the cost of device state switching and improving the efficiency of device state switching.

[0088] The state transition judgment module 32 is used to determine whether it is necessary to control the target physical device to perform a state transition based on the comparison result between the current state and the target state, and / or the state transition conditions.

[0089] The control strategy generation module 33 is used to obtain the target state transition conditions that the target physical device needs to meet when it is determined that the target physical device needs to switch states, and to determine the device control strategy that matches the target state transition conditions.

[0090] The device control module 34 is used to generate device control instructions corresponding to the device control strategy and send the device control instructions to the target physical device to control the target physical device to execute the device control instructions.

[0091] The technical solution in this embodiment, through the cooperation of the twin model construction module 31, the state switching judgment module 32, the control strategy generation module 33, and the device control module 34, solves the problem that the existing technology, which is highly dependent on the accuracy and timeliness of the state switching command, is prone to errors in the generation of the device control strategy or failure to execute the device state switching action on time when there are parameter deviations or transmission delays in the state switching command.

[0099] Optionally, the state update unit is specifically used to: determine whether the current state is consistent with the target state; if yes, update the current state recorded in the state model to the actual state; if no, if the predefined state update termination condition is not met, return to the operation of sending the device control command to the target physical device until the actual state is consistent with the target state, and then update the current state recorded in the state model to the actual state.
