Description

[0002] In high-quality smart operation and maintenance service scenarios for residential communities, there are a massive number of ubiquitous terminal devices, such as intelligent security components, elevator controllers, and outdoor environmental monitoring sensors. To address the challenges of rapid connection, data sharing difficulties, and severe silo issues among various intelligent systems in community operation and maintenance services, existing technologies often employ a single-point integration model. Single-point integration refers to a model that independently and distributedly connects and manages a massive number of ubiquitous terminal devices. However, the reliability of the single-point integration model is insufficient. When a single edge gateway is overloaded or its signal weakens due to device movement, the device typically needs to undergo a hard handover process of "disconnection-global scan-re-re-pairing and authentication." This process is not only time-consuming but also highly susceptible to the loss of critical business data (such as security alarms and elevator fault signaling) during the handover vacuum period, seriously affecting the quality and security of smart operation and maintenance services.

Detailed Implementation

[0024] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0025] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this document means two or more. Moreover, the term "at least one" in this document means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0026] As described in the background section, the reliability of the single-point integration model is insufficient. When the computing power of a single edge gateway is overloaded or the signal is attenuated due to device movement, the device typically needs to undergo a hard handover process of "disconnection-global scan-re-pairing and authentication". This process is not only time-consuming, but also highly susceptible to the loss of critical business data (such as security alarms and elevator fault signaling) during the handover vacuum period, seriously affecting the quality and security of intelligent operation and maintenance services.

[0027] To address the aforementioned issues, this application proposes an adaptive synchronization interaction method for cell operation and maintenance equipment. The cell operation and maintenance equipment includes terminal equipment, a first edge gateway, and a second edge gateway, and as follows... Figure 1 and 3As shown, the method includes the following steps S1-S5: S1, the first edge gateway calculates its own interaction tension index based on the service burst rate of the terminal device, and when the interaction tension index exceeds a preset security threshold, it sends a synchronization interaction request and the shadow context information of the terminal device to the second edge gateway; S2, the second edge gateway writes the shadow context into its own local protocol stack parsing list and pre-configures a pairless virtual channel for the terminal device; S3, the first edge gateway sends an adaptive switching command to the terminal device; S4, after receiving the adaptive switching command, the terminal device switches its own radio frequency channel to the frequency band of the second edge gateway; S5, after establishing a handshake with the second edge gateway through the pairless virtual channel in the frequency band, the terminal device synchronously sends data to both the first and second edge gateways.

[0028] Therefore, this embodiment utilizes a computing power tension sensing mechanism on the gateway side. The first edge gateway calculates the interaction tension index in real time and actively initiates a switch when it exceeds a safety threshold, avoiding the traditional hard switch process of "disconnect-scan-reconnect". Simultaneously, through shadow context pre-setting technology, the context information of the terminal device is pre-written into the protocol stack parsing list of the second edge gateway, establishing a pairing-free virtual channel for it. This allows the terminal device to directly establish a connection without re-authentication after switching radio frequency channels. After the switch is completed, the overlapping window mechanism allows the terminal device to send data to both the old and new gateways simultaneously, ensuring the absolute continuity and zero loss of multi-source data during the switch vacuum period. This achieves lossless and smooth switching interaction between terminal devices and distributed gateways, effectively solving the problem of easy loss of critical business data in single-point integration mode.

[0029] In this embodiment, the community operation and maintenance equipment also includes a distributed data cleaning engine and a smart operation and maintenance service platform, and as follows: Figure 2 As shown, the method of this application further includes steps S6-S7: S6, the first edge gateway and the second edge gateway push the data received by the terminal device during the switching window period to the distributed data cleaning engine of the cloud edge in parallel; S7, the distributed data cleaning engine performs deduplication and alignment splicing processing on the data based on the sequence number, and pushes the processed data to the intelligent operation and maintenance service platform for fusion.

[0030] Therefore, in this embodiment, during the switching window, the first edge gateway and the second edge gateway receive the same data stream sent by the terminal device in parallel, and simultaneously push the data they receive to the distributed data cleaning engine at the cloud edge. This engine uses the data sequence number to perform precise deduplication and alignment splicing processing on the two data streams, effectively eliminating data redundancy, timing disorder, or omissions that may occur due to device switching. This ensures that the fused data finally pushed to the intelligent operation and maintenance service platform has absolute continuity and integrity, completely avoiding the risk of losing critical business data (such as security alarms and elevator fault signaling) during the switching vacuum period in the traditional hard switching process, and significantly improving the quality and security of intelligent operation and maintenance services.

[0031] In this embodiment, step S3 includes: after receiving the adaptive switching instruction, the terminal device suspends the current communication state machine in its internal system, enters the micro-timeslot dual state machine mode, and when the timestamp specified by the adaptive switching instruction is reached, adjusts the radio frequency communication module according to the channel parameters to switch its own radio frequency channel to the frequency band of the second edge gateway.

[0032] Therefore, it can be seen that after receiving the adaptive switching command, the terminal device in this embodiment does not immediately interrupt communication, but suspends the current communication state machine and enters the micro-timeslot dual-state machine mode. That is, within a very short time window, it simultaneously maintains the old connection state with the first edge gateway and the new connection preparation state with the second edge gateway. When the precise timestamp specified by the command is reached, the terminal device smoothly adjusts the radio frequency module according to the channel parameters to complete the channel switching, avoiding the service interruption caused by the forced reset of the state machine during the traditional hard switching process. At the same time, by using the local buffer continuation mechanism, the terminal device can temporarily store the critical business data (such as security alarms and elevator fault signals) that cannot be sent in time during the switching process in the local buffer. After establishing a pairless virtual channel with the second edge gateway, it can immediately resume transmission, thereby completely eliminating the risk of data packet loss during the switching vacuum period and ensuring zero loss and continuous reliable transmission of intelligent operation and maintenance business data in a highly dynamic network environment.

[0033] In this embodiment, the first edge gateway calculates its own interaction tension index in the following manner:

[0034] in, , and These are the first, second, and third weight parameters, respectively. The computing power utilization rate of the first edge gateway. The queue congestion rate of the first edge gateway. The rate of change of the service status of the associated nodes managed by the first edge gateway over time. This represents the interaction tension index of the first edge gateway.

[0035] Therefore, this embodiment, by constructing an interaction tension index that includes computing power utilization, queue congestion rate, and the rate of change in the business status of associated nodes, and introducing multi-dimensional weight parameters for weighted quantification, can comprehensively and dynamically reflect the current load pressure and interaction tension of the first edge gateway. This mechanism not only comprehensively considers the resource consumption and transmission congestion of the first edge gateway itself, but also incorporates the impact of business fluctuations of surrounding associated nodes, thereby achieving an accurate assessment of the operating status of the first edge gateway. This provides a scientific and quantitative decision-making basis for subsequent task scheduling optimization, load balancing strategy formulation, and system stability assurance, effectively improving the overall response efficiency and service quality of the edge computing network.

[0036] In this embodiment,

[0037]

[0038]

[0039] in, This indicates the amount of resources already used by the first edge gateway. This represents the total resource capacity of the first edge gateway. This indicates the current queue length of the first edge gateway. This represents the maximum capacity of the first edge gateway queue, where n is the number of devices participating in the calculation. This represents the weight coefficient of the i-th associated node. This represents the business status quantity of the i-th associated node, where t is the current time. This represents the static impact coefficient of the CPU. This represents the static impact coefficient of memory. This indicates the CPU utilization of the first edge gateway. This indicates the memory utilization rate of the first edge gateway.

[0040] In this embodiment,

[0041]

[0042]

[0043] in, This is the sensitivity amplification factor. k can be 5, and its specific value can be dynamically changed, without being limited by this embodiment.

[0044] Therefore, this embodiment introduces an adaptive weight calculation mechanism (α, β, γ) based on the Softmax function, and uses a sensitivity amplification coefficient k to automatically adjust the weight ratio of each indicator. This enables the system to dynamically identify and focus on the current "shortcoming" or key bottleneck (i.e., the indicator with the highest value receives greater weight) based on the real-time status. This dynamic adaptive mechanism effectively avoids the problem of evaluation distortion in complex and ever-changing environments with fixed weights, and significantly improves the accuracy and robustness of the interaction tension index calculation. As a result, it provides more timely and targeted decision support for resource scheduling and congestion control in edge computing scenarios.

[0045] In this embodiment, the adaptive handover instruction includes the gateway physical address of the second edge gateway, channel parameters, and a precise handover timestamp. The shadow context includes: session key, identity resolution key, frequency hopping clock anchor point, and data sequence number breakpoint.

[0046] Therefore, this embodiment encapsulates the gateway physical address, channel parameters, and precise switching timestamp of the second edge gateway in the adaptive switching instruction. The terminal device can complete the directional switching of the radio frequency channel and the gateway within millisecond precision. At the same time, by using the shadow context composed of session key, identity resolution key, frequency hopping clock anchor point, and data sequence number breakpoint, the second edge gateway can seamlessly take over the communication status and service context of the terminal device without re-initiating full authentication. This achieves an ultimate switching experience with zero interruption, no pairing required, and continuous transmission, significantly reducing the switching latency and data loss risk in the multi-gateway collaboration process in intelligent operation and maintenance scenarios.

[0047] The following example illustrates the high-frequency video stream and control signaling transmission of an unmanned electronic patrol robot moving across areas within a residential community: Sudden Tension Perception: When the unmanned inspection robot detects an anomaly in the Building A area, it triggers the intelligent recognition camera to generate high-frequency burst data, causing a sharp increase in the derivative of the data generation rate of the first edge gateway in Building A. The interaction tension index of the first edge gateway in Building A is calculated to have exceeded the safety threshold.

[0048] Gateway-side paving: The first edge gateway in Building A immediately uses the robot's communication key and the last confirmed video frame sequence number (e.g., Seq=2048) as a "shadow context" and rapidly synchronizes it to the second edge gateway in Building B, which has abundant computing power, via the intranet. The second edge gateway in Building B silently writes this credential into its underlying resolution list, and the communication of the originally connected smart home devices and environmental sensors remains unaffected.

[0049] Terminal-side transition: The first edge gateway in Building A sends an adaptive switching command to the robot. When the robot reaches the timestamp specified in the command, it starts a dual-state machine at the bottom layer, stops sending packets to the first edge gateway in Building A, instantly switches the radio frequency channel to the frequency band of the second edge gateway in Building B, and initiates a directional handshake using the pre-embedded key to complete the millisecond-level seamless migration.

[0050] Edge-cloud data fusion: During the brief moment of switching (approximately a few milliseconds), the robot temporarily stores the newly generated video frames (Seq=2049,2050) in a local circular buffer. Upon connecting to the second edge gateway in Building B, the buffered frames are immediately sent out. The tail data collected by the first edge gateway and the header data collected by the second edge gateway in Building B are deduplicated and aligned according to their sequence numbers in a distributed data cleaning engine, ultimately presenting a continuous monitoring feed without lag or data loss on the integrated smart operation and maintenance service platform for the "home-community" system.

[0051] In summary, compared to existing methods that use a single-point integration model to independently and distributedly connect and manage massive ubiquitous terminal devices, this application utilizes a gateway-side computing power tension sensing mechanism. The first edge gateway calculates the interaction tension index in real time and proactively initiates a handover when it exceeds a safety threshold, avoiding the traditional hard handover process of "disconnect-scan-reconnect." Simultaneously, through shadow context pre-setting technology, the context information of the terminal device is pre-written into the protocol stack parsing list of the second edge gateway, establishing a pairing-free virtual channel. This allows the terminal device to directly establish a connection without re-authentication after switching radio frequency channels. After the handover is complete, an overlapping window mechanism is used to allow the terminal device to simultaneously send data to both the old and new gateways, ensuring absolute continuity and zero loss of multi-source data during the handover vacuum period. This achieves lossless and smooth handover interaction between terminal devices and distributed gateways, effectively solving the problem of easily lost critical business data in the single-point integration model.
