Technical Field

[0001] This application relates to the field of power engineering technology, and in particular to a control method and a power lateral isolation system for a power lateral isolation cluster. Background Technology

[0002] As a key device for cross-regional and cross-security domain communication, the power horizontal isolation device is used to achieve physical isolation and controllable data transmission of power networks with different security levels, and is an important component of the power communication security system.

[0003] Currently, most power horizontal isolation devices operate independently. Due to differences in safety levels, bandwidth, transmission delays, and fault states among different isolation devices, the matching accuracy between power horizontal isolation devices and communication requirements is sometimes insufficient, making it impossible to dynamically adapt to different communication needs, resulting in poor versatility of power horizontal isolation devices. Summary of the Invention

[0014] Identify the target isolation cluster that includes each selected lateral isolation device.

[0015] In one embodiment, controlling selected lateral isolation devices in the target isolation cluster to communicate based on cross-regional isolation communication requests includes:

[0039] The selected lateral isolation device that matches the isolation channel status information of the primary node device is identified as the backup node device.

[0040] In one embodiment, the method further includes:

[0041] If a selected horizontal isolation device fails within the target isolation cluster, update the isolation channel status information of the failed selected horizontal isolation device.

[0073] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0074] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0075] In one exemplary embodiment, such as Figure 1 As shown, a control method for a power horizontal isolation cluster is provided, including the following steps S110 to S140. Wherein:

[0076] Step S110: Upon receiving a cross-regional isolation communication request, obtain the isolation channel status information of multiple power horizontal isolation devices;

[0077] Cross-regional isolation communication requests refer to communication requests within the power system network that require isolation across different regions. The power system network is divided into different regions based on security levels. For example: Production Control Region (Zones I / II): responsible for core production operations such as real-time monitoring and dispatching, with the highest security level. Management Information Region (Zones III / IV): responsible for non-production operations such as office work and management, and connected to external networks (such as the Internet), with a lower security level than the Production Control Region.

[0078] Among them, the power lateral isolation device, officially known as a power-specific lateral unidirectional safety isolation device, is installed between different regions. Through unidirectional data transmission, it achieves an isolation strength approaching or reaching physical isolation. Isolation channel status information refers to the status information of the isolation channel through which the power lateral isolation device communicates. This information can include status parameters describing the isolation channel status from multiple dimensions, such as security level, transmission bandwidth, transmission delay, and fault status. An isolation channel refers to the physical or logical data transmission link established within or through the power lateral isolation device, used to connect regions with different security levels.

[0079] For example, this embodiment can collect and update the isolation channel status information of multiple power horizontal isolation devices in real time, and then obtain the latest isolation channel status information of multiple power horizontal isolation devices when a cross-regional isolation communication request is received. In order to facilitate the matching of subsequent isolation channel status information, this embodiment can perform vector transformation on the status parameters of multiple dimensions in the isolation channel status information to obtain the isolation vector corresponding to the power horizontal isolation device, thereby storing the isolation channel status information of the power horizontal isolation device in vector format.

[0080] Step S120: Extract the target requirement parameters from the cross-regional isolation communication request;

[0081] Among them, the target requirement parameters are the parameters that describe the communication requirements in the cross-regional isolation communication request.

[0082] This embodiment can parse cross-regional isolation communication requests and extract target requirement parameters from them. For example, the target requirement parameters include at least the security level threshold and fault state admission conditions required by the cross-regional isolation communication request, and may also include requirement parameters such as the bandwidth requirement threshold and transmission delay limit required by the cross-regional isolation communication request.

[0083] Step S130: Match the target demand parameters with the isolation channel status information corresponding to each power horizontal isolation device, and select at least a portion of the power horizontal isolation devices to form a target isolation cluster; each selected horizontal isolation device in the target isolation cluster is matched with the target demand parameters.

[0084] As an example, this embodiment can determine the safety level threshold and fault state admission conditions in the target requirement parameters. Based on the status information of each isolation channel, power horizontal isolation devices with a safety level lower than the safety level threshold or whose fault state does not meet the fault state admission conditions are removed from each power horizontal isolation device. Selected horizontal isolation devices that match the target requirement parameters are obtained, and a target isolation cluster containing each selected horizontal isolation device is determined.

[0085] As another example, this embodiment can transform the target demand parameters into a vector to obtain a target demand vector. Then, it performs similarity matching between this target demand vector and the isolation vectors corresponding to the isolation channel status information of each power lateral isolation device. Power lateral isolation devices with a similarity higher than a preset similarity threshold are then identified. This embodiment can determine all power lateral isolation devices with a similarity higher than the preset similarity threshold as selected lateral isolation devices. Alternatively, this embodiment can determine only a portion of the power lateral isolation devices with a similarity higher than the preset similarity threshold as selected lateral isolation devices. Finally, a target isolation cluster composed of these selected lateral isolation devices is obtained.

[0086] In some embodiments, the isolation channel status information includes security level and fault status; matching the target requirement parameters with the isolation channel status information corresponding to each power horizontal isolation device, and selecting at least a portion of the power horizontal isolation devices to form the target isolation cluster, including:

[0087] Step S131: Determine the safety level threshold and fault state admission conditions in the target requirement parameters;

[0088] Step S132: Based on the status information of each isolation channel, remove power horizontal isolation devices from each power horizontal isolation device whose safety level is less than the safety level threshold or whose fault status does not meet the fault status access conditions, and obtain the selected horizontal isolation device that matches the target requirement parameters.

[0089] Step S133: Determine the target isolation cluster containing each selected lateral isolation device.

[0090] The isolation channel status information includes security level and fault status. The security level describes the level of communication security corresponding to the isolation channel of the power lateral isolation device, such as level one, level two, level three, etc. The fault status describes whether there is a fault in the operation of the power lateral isolation device, such as no fault or fault present. Of course, more specific information can also be included, such as fault type and fault severity.

[0091] This embodiment first determines the security level threshold and fault state admission conditions in the target requirement parameters, thereby determining the security level and fault state requirements for the cross-regional isolation communication request. Then, based on the status information of each isolation channel, power lateral isolation devices with security levels lower than the security level threshold or fault states that do not meet the fault state admission conditions are removed from each power lateral isolation device. Therefore, this embodiment can select power lateral isolation devices with security levels greater than or equal to the security level threshold and fault states that meet the fault state admission conditions as the selected lateral isolation devices matching the target requirement parameters. It can be understood that this embodiment can select all power lateral isolation devices with security levels greater than or equal to the security level threshold and fault states that meet the fault state admission conditions as the selected lateral isolation devices matching the target requirement parameters. This embodiment can also select a portion of power lateral isolation devices with security levels greater than or equal to the security level threshold and fault states that meet the fault state admission conditions as the selected lateral isolation devices matching the target requirement parameters. Therefore, this embodiment determines the target isolation cluster containing each selected lateral isolation device.

[0092] This embodiment can screen each power horizontal isolation device according to the safety level threshold and fault state admission conditions in the target requirement parameters to obtain the selected horizontal isolation device that matches the target requirement parameters. This ensures that each selected horizontal isolation device in the target isolation cluster is adapted to the target requirement parameters to meet the communication requirements of cross-regional isolation communication requests.

[0093] Step S140: Based on the cross-regional isolation communication request, control each selected horizontal isolation device in the target isolation cluster to communicate.

[0094] For example, in this embodiment, at least one selected lateral isolation device can be selected as the master node device of the target isolation cluster, and other selected lateral isolation devices can be selected as slave node devices of the target isolation cluster. Then, a communication channel carrying cross-regional isolation communication requests can be established through the master node device. Subsequently, the master node device can split the cross-regional isolation communication request into multiple communication tasks and distribute them to each slave node device, so that each slave node device can execute the received communication task through the communication channel. As another example, in this embodiment, a communication channel carrying cross-regional isolation communication requests can also be established through an additional control device. The control device can then split the cross-regional isolation communication request into multiple communication tasks and distribute them to each selected lateral isolation device in the target isolation cluster, so that each selected lateral isolation device can execute the received communication task through the communication channel.

[0095] In some embodiments, the method further includes:

[0096] Step S210: If a selected horizontal isolation device fails within the target isolation cluster, update the isolation channel status information of the failed selected horizontal isolation device.

[0097] Step S220: Return to the step of obtaining the isolation channel status information of multiple power lateral isolation devices.

[0098] To ensure the target isolation cluster remains compatible with cross-regional isolation communication requests, this embodiment continuously monitors the status of each selected lateral isolation device within the target isolation cluster. Furthermore, in the event of a failure of a selected lateral isolation device within the target isolation cluster, this embodiment updates the isolation channel status information of the failed device and returns to the step of retrieving the isolation channel status information of multiple power lateral isolation devices. Thus, this embodiment can re-execute the process of retrieving the isolation channel status information of multiple power lateral isolation devices, extract target requirement parameters from the cross-regional isolation communication request, match the target requirement parameters with the isolation channel status information corresponding to each power lateral isolation device, and select at least a portion of the power lateral isolation devices to form the target isolation cluster. Therefore, this embodiment reconstructs a new target isolation cluster after a selected lateral isolation device fails.

[0099] Therefore, in the event of a failure of a selected lateral isolation device, this embodiment synchronously adjusts the selected lateral isolation device within the target isolation cluster, thereby ensuring that the target isolation cluster is always compatible with cross-regional isolation communication requests.

[0100] In the aforementioned control method for power horizontal isolation clusters, upon receiving an inter-regional isolation communication request, the isolation channel status information of multiple power horizontal isolation devices is obtained. Target demand parameters are extracted from the inter-regional isolation communication request, and these parameters are matched with the isolation channel status information corresponding to each power horizontal isolation device. At least a portion of the power horizontal isolation devices are selected to form a target isolation cluster. Each selected horizontal isolation device within the target isolation cluster is matched with the target demand parameters, and communication is controlled according to the inter-regional isolation communication request. This application, upon receiving an inter-regional isolation communication request, constructs a target isolation cluster that matches the requirements of the request, thereby enabling the target isolation cluster to dynamically adapt to different communication needs and improving the versatility of power horizontal isolation devices.

[0101] In one exemplary embodiment, such as Figure 2 As shown, based on the cross-regional isolation communication request, the system controls the selected horizontal isolation devices in the target isolation cluster to communicate, including steps S310 to S330. Wherein:

[0102] Step S310: Select at least one selected horizontal isolation device from the target isolation cluster as the master node device of the target isolation cluster, and select the other selected horizontal isolation devices as the slave node devices of the target isolation cluster.

[0103] Step S320: Establish a communication channel through the master node device to carry cross-regional isolation communication requests;

[0104] Step S330: The master node device splits the cross-regional isolation communication request into multiple communication tasks and distributes them to each slave node device, so that each slave node device can execute the received communication tasks through the communication channel.

[0105] This embodiment can select at least one selected lateral isolation device from the target isolation cluster as the master node device of the target isolation cluster, and use other selected lateral isolation devices as slave node devices of the target isolation cluster. For example, this embodiment can randomly select at least one selected lateral isolation device from the target isolation cluster as the master node device of the target isolation cluster, and use other selected lateral isolation devices as slave node devices of the target isolation cluster. As another example, this embodiment can also determine the bandwidth requirement threshold in the target requirement parameters, remove selected lateral isolation devices from the target isolation cluster whose transmission bandwidth is less than the bandwidth requirement threshold, obtain a candidate device set, and select at least one selected lateral isolation device from the candidate device set whose historical failure frequency is lower than a preset frequency threshold and whose transmission delay is the smallest as the master node device of the target isolation cluster. As another example, this embodiment can also determine the transmission delay, transmission bandwidth, historical failure frequency, and security level of each selected lateral isolation device in the candidate device set, determine the comprehensive score of each selected lateral isolation device in the candidate device set based on the transmission delay, transmission bandwidth, historical failure frequency, and security level, and select at least one selected lateral isolation device with the highest comprehensive score as the master node device of the target isolation cluster.

[0106] Furthermore, in this embodiment, a communication channel carrying cross-regional isolation communication requests can be established through the master node device. It can be understood that this communication channel is a data channel for communication between the initiating region and the target region of the cross-regional isolation communication request. In this embodiment, through this communication channel, one end of the master node device is connected to the initiating region of the cross-regional isolation communication request, and the other end of the master node device is connected to each slave node device. Each slave node device is connected to the target region of the cross-regional isolation communication request.

[0107] Therefore, in this embodiment, the cross-regional isolation communication request can be split into multiple communication tasks by the master node device and distributed to each slave node device, so that each slave node device can execute the received communication task through the communication channel. For example, this embodiment can split the cross-regional isolation communication request according to the number of slave node devices, where the number of communication tasks is a multiple of the number of slave node devices. This embodiment can also split the cross-regional isolation communication request according to a preset data volume, where the data volume of each communication task is less than or equal to the preset data volume.

[0108] This embodiment uses a cluster architecture with at least one master node device and multiple slave node devices. This eliminates the need for additional high-standard control devices to build communication channels and split cross-regional isolation communication requests. This helps to reduce additional costs while ensuring that the target isolated cluster can perform communication tasks in accordance with the requirements of cross-regional isolation communication requests.

[0109] In some embodiments, the isolation channel status information includes transmission bandwidth, transmission delay, and historical failure frequency; selecting at least one selected lateral isolation device from the target isolation cluster as the master node device of the target isolation cluster includes:

[0110] Step S311: Determine the bandwidth requirement threshold in the target requirement parameters;

[0111] Step S312: Remove selected horizontal isolation devices from the target isolation cluster whose transmission bandwidth is less than the bandwidth requirement threshold to obtain a candidate device set.

[0112] Step S313: Select at least one selected horizontal isolation device from the candidate device set that has a historical failure frequency lower than a preset frequency threshold and the smallest transmission delay as the master node device of the target isolation cluster.

[0113] The preset frequency threshold is a pre-set value for the historical fault frequency.

[0114] To ensure the performance of the master node device, this embodiment determines a bandwidth requirement threshold in the target requirement parameters. Selected lateral isolation devices with transmission bandwidth less than the bandwidth requirement threshold are removed from the target isolation cluster, thus obtaining a set of candidate devices that meet the target requirement parameters. Furthermore, this embodiment selects at least one selected lateral isolation device from the candidate device set with a historical failure frequency lower than a preset frequency threshold and the lowest transmission delay as the master node device of the target isolation cluster. Therefore, in this embodiment, by using the bandwidth requirement threshold, preset frequency threshold, and transmission delay screening, the stability and transmission performance of the master node device are guaranteed, avoiding reliability issues in subsequent communication.

[0115] In some embodiments, the method further includes:

[0116] Step S410: Determine the transmission delay, transmission bandwidth, historical failure frequency, and security level of each selected lateral isolation device in the candidate device set;

[0117] Step S420: Determine the comprehensive score of each selected lateral isolation device in the candidate device set based on transmission delay, transmission bandwidth, historical failure frequency and security level.

[0118] Step S430: Select at least one of the selected horizontal isolation devices with the highest comprehensive score as the master node device of the target isolation cluster.

[0119] For example, this embodiment can determine the transmission delay, transmission bandwidth, historical failure frequency, and security level of each selected lateral isolation device in the candidate device set. Then, this embodiment can normalize the transmission delay, transmission bandwidth, historical failure frequency, and security level to obtain normalized values. The sum of these normalized values ​​is then used as the comprehensive score for each selected lateral isolation device in the candidate device set. As another example, this embodiment can perform a weighted calculation on the normalized values ​​to obtain a weighted value as the comprehensive score for each selected lateral isolation device in the candidate device set. It is understood that when calculating the comprehensive score, the weights corresponding to transmission delay, transmission bandwidth, historical failure frequency, and security level can be selected according to requirements. For example, the weight corresponding to transmission delay is 40%, with lower transmission delay resulting in a higher score, representing the primary pursuit of low latency. The weight corresponding to transmission bandwidth is 30%, with higher bandwidth resulting in a higher score to ensure service carrying capacity. The weight corresponding to historical failure frequency is 20%, with lower failure frequency resulting in a higher score to ensure device operational reliability. The weight corresponding to security level is 10%, with higher security levels resulting in a higher score to enhance security adaptability. Then, at least one selected horizontal isolation device with the highest comprehensive score is selected as the master node device of the target isolation cluster.

[0120] This embodiment evaluates the performance of each selected lateral isolation device in the candidate device set from multiple dimensions to ensure that, under any circumstances, the selected lateral isolation device with better performance can always be selected as the master node device of the target isolation cluster.

[0121] In one exemplary embodiment, such as Figure 3 As shown, the master node device splits the cross-regional isolation communication request into multiple communication tasks and distributes them to each slave node device, so that each slave node device can execute the received communication task, including steps S510 to S550. Wherein:

[0122] Step S510: Obtain the first bandwidth load rate of the master node device;

[0123] Step S520: Determine the load balancing range based on the first bandwidth load rate;

[0124] Step S530: The master node device splits the cross-regional isolation communication request into multiple communication tasks and assigns each communication task to each slave node device.

[0125] Step S540: Obtain the second bandwidth load rate of each secondary node device;

[0126] Step S550: If the second bandwidth load rate of the secondary node device is greater than or equal to the upper limit of the load balancing range, the communication tasks of the secondary node device are allocated to the lightly loaded node device, wherein the lightly loaded node device is a secondary node device whose second bandwidth load rate is less than the lower limit of the load balancing range.

[0127] The first bandwidth load factor is the proportion of the total bandwidth currently loaded by the primary node device, such as 50%, 60%, or 70%. The load balancing range is smaller than the first bandwidth load factor, for example, 50% to 80% of the first bandwidth load factor. This load balancing range can be selected according to requirements. The second bandwidth load factor is the proportion of the total bandwidth currently loaded by the secondary node device, such as 50%, 60%, or 70%.

[0128] like Figure 4 As shown, this embodiment can detect the load of the master node device's transmission bandwidth to obtain the first bandwidth load rate of the master node device, and then determine the load balancing threshold based on the first bandwidth load rate. The load balancing threshold is less than the first bandwidth load rate. Then, based on the load balancing threshold, a load balancing range including the load balancing threshold is determined. For example, the load balancing range is the load balancing threshold ± m%.

[0129] The primary node device then breaks down cross-regional isolation communication requests into multiple communication tasks and distributes these tasks to secondary node devices. For example, this embodiment distributes the tasks sequentially to each secondary node device. During this process, the bandwidth load of each secondary node device is monitored to obtain its second bandwidth load rate. If the second bandwidth load rate of a secondary node device is greater than or equal to the upper limit of the load balancing range, it indicates that the current load on the secondary node device is too high. To balance the load across the secondary node devices, this embodiment can distribute the communication tasks of that secondary node device to lightly loaded node devices, where a lightly loaded node device is one whose second bandwidth load rate is less than the lower limit of the load balancing range.

[0130] This embodiment determines the load balancing range by using the first bandwidth load rate of the master node device, so that the load balancing of each slave node device fluctuates with the load of the master node, avoiding a fixed threshold range. Under low load conditions, some slave node devices operate at a moderate level, while other slave node devices can operate at a very light level or even be idle, thereby ensuring the load balancing of each slave node device under any operating condition.

[0131] In some embodiments, selecting at least one selected lateral isolation device from the target isolation cluster as the master node device of the target isolation cluster includes:

[0132] Step S610: Select at least one standby node device from the target isolated cluster and synchronize the configuration of the standby node device with the master node device;

[0133] Step S620: If the fault status of the primary node device is "fault exists", start the backup node device to replace the primary node device.

[0134] Configuration synchronization refers to keeping the configuration parameters of the standby node device consistent with those of the primary node device.

[0135] In this embodiment, at least one backup node device can be selected from the target isolation cluster. For example, in this embodiment, at least one selected lateral isolation device can be randomly selected from the target isolation cluster as a backup node device. In this embodiment, the isolation channel status information of each selected lateral isolation device in the target isolation cluster can also be matched with the isolation channel status information of the master node device, and the selected lateral isolation device that matches the isolation channel status information of the master node device is determined as the backup node device.

[0136] like Figure 5 As shown, this embodiment further synchronizes the configuration of the standby node device with the primary node device. When the primary node device fails, the standby node device is activated to replace it. That is, the primary node device migrates its running processes to the standby node device, and then shuts it down after the migration. Because the standby node device has been pre-configured and synchronized with the primary node device, seamless processing of the migrated running processes is ensured, thereby guaranteeing the operational stability of the target isolated cluster in the event of a primary node device failure. Furthermore, secondary node devices (ordinary nodes) can also be pre-configured with backup target node devices, allowing the communication tasks of the secondary node device to be migrated to the target node device in the event of a secondary node device failure.

[0137] In some embodiments, selecting at least one backup node device from the target isolated cluster includes:

[0138] Step S611: Match the isolation channel status information of each selected horizontal isolation device in the target isolation cluster with the isolation channel status information of the master node device;

[0139] Step S612: Select the horizontal isolation device that matches the isolation channel status information of the master node device and determine it as the backup node device.

[0140] To ensure the operational stability of the target isolation cluster in the event of a master node failure, this embodiment can further match the isolation channel status information of each selected lateral isolation device in the target isolation cluster with the isolation channel status information of the master node device. The selected lateral isolation devices that match the isolation channel status information of the master node device are then designated as backup node devices. For example, this embodiment can convert the isolation channel status information of each selected lateral isolation device in the target isolation cluster into corresponding isolation vectors, and the isolation channel status information of the master node device into master node vectors. By calculating the similarity between each isolation vector and the master node vector, the selected lateral isolation devices corresponding to isolation vectors with similarity higher than a preset similarity threshold are determined as the selected lateral isolation devices that match the isolation channel status information of the master node device. The formula for calculating this similarity is as follows:

[0141] ;

[0142] in, The master node vector of the master node device. To select the isolation vector corresponding to the lateral isolation device, The dot product of two vectors. , These are the magnitudes of the two vectors, respectively.

[0143] Therefore, if the similarity value is ≥90%, the selected lateral isolation device can be determined to meet the selection requirements of the backup node device; if the similarity value is <90%, the selected lateral isolation device will be eliminated.

[0144] This embodiment matches the isolation channel status information of each selected horizontal isolation device in the target isolation cluster with the isolation channel status information of the master node device. The selected horizontal isolation devices that match the isolation channel status information of the master node device are identified as backup node devices. This ensures that the selected backup node devices are basically consistent with the master node devices in terms of isolation channel status information, which helps to ensure the operational stability of the target isolation cluster in the event of a failure of the master node device.

[0145] like Figure 6As shown, in some embodiments, a power lateral isolation system is proposed. The power lateral isolation system includes: a cluster control unit, at least two power lateral isolation devices, and a vector scheduling module. The cluster control unit establishes bidirectional communication connections with each power lateral isolation device and the vector scheduling module. The vector scheduling module is used to construct and dynamically update the isolation channel status information of each power lateral isolation device. The cluster control unit is used to obtain the isolation channel status information of multiple power lateral isolation devices upon receiving a cross-regional isolation communication request; and to extract target demand parameters from the cross-regional isolation communication request. The vector scheduling module is also used to match the target demand parameters with the isolation channel status information corresponding to each power lateral isolation device, selecting at least a portion of the power lateral isolation devices to form a target isolation cluster; each selected lateral isolation device in the target isolation cluster is matched with the target demand parameters. The target isolation cluster is used to control the communication of each selected lateral isolation device in the target isolation cluster according to the cross-regional isolation communication request. Figure 7As shown, after system initialization, during operation, the cluster control unit establishes bidirectional communication connections with each power horizontal isolation device and the vector scheduling module to ensure smooth transmission of control commands, status data, and vector information among nodes. The vector scheduling module starts running, constructing an isolation vector model for each power horizontal isolation device and its corresponding isolation channel for cross-security domain data transmission. This model quantifies the multi-dimensional status parameters of each device into isolation vectors, with quantification dimensions including at least four core parameters: security level, bandwidth, transmission delay, and fault status. The vector scheduling module dynamically updates each isolation vector in real time based on changes in device operating status and channel conditions, ensuring that the isolation vectors always reflect the latest actual capabilities of each device. The cluster control unit receives externally input cross-regional isolation communication requests, parses these requests, and extracts target vector parameters from the communication requests. Target vector parameters include at least the security level threshold, bandwidth requirement threshold, transmission delay upper limit, and fault status admission conditions required by the communication request, and constructs the target vector accordingly. The vector scheduling module matches and compares the target vector with the isolation vectors of each power horizontal isolation device, selecting devices whose isolation vectors meet the target vector requirements in all dimensions, and forming these devices into an isolation cluster. The vector scheduling module uses scheduling algorithms to coordinate and schedule all devices within the isolated cluster, enabling cluster collaboration, load balancing, and redundant backup configuration. Based on cross-regional isolation communication needs, the isolated cluster dynamically establishes communication channels on selected horizontal power isolation devices to carry those communication needs, completing cross-regional data transmission. When communication needs terminate, the corresponding channels are dynamically dismantled, releasing the occupied bandwidth and session resources. When any device in the isolated cluster fails, the vector scheduling module immediately detects the fault and updates the device's isolation vector, marking the fault state dimension as abnormal. Subsequently, the system triggers a rescheduling process, selecting new devices from available devices to supplement the cluster, and migrating the services carried by the faulty node to healthy nodes, ensuring the continuity of cross-regional isolation communication.
