Description

Technical Field

[0001] The present application relates to the field of information technology, and in particular to a method, device, equipment and medium for monitoring the status of a charging pile relay. Background Art

[0002] In distributed charging pile systems, the dynamic deployment and remote control of safety relays face multiple, closely intertwined technical challenges. First, real-time data collection from auxiliary contacts requires high-frequency, low-latency encrypted transmission. However, charging piles are distributed across multiple regions, making signals susceptible to interference. This requires the coordinated use of cross-regional anti-interference technology and reliability verification mechanisms to ensure data packet integrity. Second, relay status monitoring relies on a dynamic resource pool allocation algorithm and a state prediction model. This requires accurate analysis of contact signals and classification of operating states. However, load balancing scheduling can lead to analysis delays due to surging data volumes, impacting the real-time nature of anomaly detection. Algorithms require optimization to balance computational efficiency and accuracy. After locating an abnormal relay, isolation switching technology requires rapid generation of control commands. However, command encryption and latency optimization require a trade-off between safety and response speed. Resource prioritization can lead to scheduling conflicts due to concurrent demands from multiple devices. Distributed, synchronous response to emergency stop signals requires that all charging piles receive the command within a specified timeframe. However, network instability can lead to signal loss during backup channel switching and anomaly feedback correction, necessitating enhanced channel redundancy and verification mechanisms. Coordinating resource sharing across multiple devices requires the dynamic recovery of idle relay resources. However, permission verification and resource allocation can be delayed due to cross-regional permission conflicts, necessitating a unified permission management module. These interrelated issues necessitate the coordinated optimization of data transmission, status analysis, command scheduling, and resource allocation to ensure system real-time performance, security, and resource utilization.

Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this specification.

[0021] As mentioned in the background technology, in a distributed charging pile system, the dynamic deployment and remote control of safety relays face multiple technical challenges, which are closely related to each other. First, the real-time collection of auxiliary contact data requires ensuring high-frequency, low-latency encrypted transmission, but the charging piles are distributed across regions and the signals are susceptible to interference. Cross-regional anti-interference technology and reliability verification mechanisms need to be coordinated to ensure the integrity of data packets. Secondly, relay status monitoring relies on the resource pool dynamic allocation algorithm and state prediction model. It is necessary to accurately analyze the contact signals and classify the working status, but load balancing scheduling may cause analysis delays due to the surge in data volume, affecting the real-time performance of anomaly detection. The algorithm needs to be optimized to balance computing efficiency and accuracy. After the abnormal relay is located, the isolation switching technology needs to quickly generate control instructions, but instruction encryption and delay optimization need to balance safety and response speed, and resource occupancy priority sorting may cause scheduling conflicts due to the concurrent needs of multiple devices. The distributed synchronous response of the emergency stop signal requires all charging piles to receive the instruction within the specified time, but the backup channel switching and abnormal feedback correction may cause signal loss due to network instability, and the channel redundancy and verification mechanism need to be enhanced. Coordinating resource sharing across multiple devices requires the dynamic recovery of idle relay resources. However, permission verification and resource allocation can be delayed due to cross-regional permission conflicts, necessitating a unified permission management module. These interrelated issues necessitate the coordinated optimization of data transmission, status analysis, command scheduling, and resource allocation to ensure system real-time performance, security, and resource utilization.

[0022] Based on the above-mentioned inventive concept, the state monitoring method of the charging pile relay provided in the embodiment of this specification is exemplarily described below.

[0023] The embodiment of this specification provides a method for monitoring the status of a charging pile relay, such as Figure 1 Shown, including: S101. Collect and monitor the status data of the relay through a remote transmission protocol to obtain the current working status data of the relay.

[0024] During the specific implementation, real-time data collection is performed on the auxiliary contacts of the safety relay through the remote command encryption transmission protocol, the relay resource pool dynamic allocation algorithm is used to continuously monitor the relay status corresponding to each charging pile, and the state prediction analysis model is used to preliminarily analyze and classify the contact signals to obtain the current working status data packet of the relay.

[0025] Using a remote command encryption transmission protocol, real-time contact signal data is acquired from the auxiliary contacts of each charging pile's safety relay and stored as a first data packet. Pre-established signal feature extraction rules are used to extract the timing characteristics of contact closure or opening from the contact signal data in the first data packet, generating a second data packet containing these timing characteristics. The timing characteristics of the contact signals are then extracted from the second data packet. Based on pre-established relay resource pool allocation rules, dynamic resource allocation is performed for the relays corresponding to each charging pile, generating a resource allocation table. For each relay in the resource allocation table, a support vector machine algorithm is used to classify the timing characteristics, obtaining preliminary relay operating status data and storing it in a third data packet. Preliminary relay operating status data is obtained from the third data packet and compared against a preset threshold range for each charging pile's relay status to generate a status classification result. The status data for each relay in the status classification result is combined with the charging pile's operation log to generate a fourth data packet containing the relay's current operating status.

[0026] Specifically, the process of obtaining real-time contact signal data of the auxiliary contacts of the charging pile safety relay through a remote command encryption transmission protocol can be understood as a secure data collection method based on network communication. Assume that in a charging pile network, the relay contact signal of each charging pile needs to be transmitted to the central server through an encrypted channel. The signal data may include the closed or open state of the contact and timestamp information. This method can ensure that the data is not tampered with during transmission, and the real-time performance can also meet monitoring requirements. Furthermore, when extracting the timing characteristics of contact closure or disconnection, pre-defined rules can be used to identify the pattern of signal changes, such as the length of time of continuous closure or the response interval after disconnection, thereby providing basic data for subsequent status judgment.

[0027] Specifically, dynamically allocating resources to relays corresponding to charging piles based on relay resource pool allocation rules can be seen as an efficient way to manage limited resources. For example, in a scenario with multiple charging piles, the resource allocation table dynamically determines which relays require more monitoring resources and which can temporarily receive less attention, based on the operating load and priority of each device. This allocation method optimizes overall monitoring efficiency. Next, when using the support vector machine algorithm to classify time series features, the extracted signal features are actually mapped to different operating status categories, such as normal operation, impending failure, or failed. This classification method can quickly distinguish the operating status of the relays, providing a precise basis for subsequent processing.

[0028] Specifically, the process of comparing the relay's preliminary operating status data against a preset threshold range can be considered a means of detecting abnormal conditions. For example, if the contact closure frequency in a charging station's relay status data is significantly higher than the normal range, the system will mark it as an abnormal state and generate a corresponding classification result. When further generating a data packet containing the current operating status in conjunction with the charging station's operation log, historical operating records in the log, such as device startup time or load changes, can be used to verify whether the current state is consistent with historical behavior. This combined approach can improve the accuracy of status determination, ensuring that the resulting data packet truly reflects the relay's operating status and providing reliable support for subsequent monitoring and maintenance.

[0029] S102: Analyze the equipment operation status according to the working status data, determine whether there is an abnormality and locate the abnormal information.

[0030] During specific implementation, based on the working status data packets obtained in the previous stage, a real-time load balancing scheduling mechanism is used to conduct an in-depth analysis of the operating status of each device. If the status data of a certain relay is detected to exceed the preset threshold range, the abnormal alarm mechanism is triggered, and the specific location and fault category information of the abnormal relay are determined using remote fault diagnosis and positioning technology.

[0031] The operating parameters of each device are extracted from the device operating status data packets obtained in the previous stage. Real-time monitoring is performed on each device's operating parameters to determine whether the relay status data exceeds the preset threshold range. If so, the corresponding device ID and relay number are recorded. Based on the recorded device ID and relay number, a remote fault diagnosis and location tool is invoked to determine the specific location information and possible fault category of the abnormal relay by comparing the relay status data with historical operation records. After determining the location information and fault category of the abnormal relay, the abnormal alarm mechanism is triggered, and the location information and fault category of the abnormal relay are sent to the monitoring center via a pre-established communication channel for subsequent processing. For the abnormal information sent to the monitoring center, the location and fault category data of the abnormal relay are saved and generated into an alarm log. This ensures that the in-depth analysis results of each device's operating status are linked to the abnormal alarm mechanism to accurately locate and classify the abnormal relay.

[0032] For example, the process of extracting operating parameters from the device working status data packet.

[0033] Specifically, the device may be a charging station, and its operating parameters include the voltage value and current value of the relay.

[0034] In one embodiment, real-time monitoring collects voltage and current data during device operation and compares it to a preset normal range threshold, such as 220-240V. If a relay voltage value exceeds this range, such as 245V, the unique identifier and relay number of the charging station are recorded. This ensures that abnormal conditions can be quickly detected, providing accurate identification for subsequent fault location.

[0035] Specifically, the remote fault diagnosis and positioning tool is implemented by querying historical operation records based on the recorded device identification and relay number.

[0036] For example, the diagnostic tool extracts the relay's operating data from the past week from a cloud database, analyzes patterns in voltage fluctuations, and compares them with current abnormal data. If persistently high voltage accompanied by abnormal current flow is detected, this could indicate a relay contact oxidation fault. This process, by comparing historical data with real-time data, identifies the fault type and location, providing a reliable basis for alerting.

[0037] In one possible implementation, after the abnormal alarm mechanism is triggered, the location information and fault category of the abnormal relay are transmitted to the monitoring center through an encrypted communication channel.

[0038] For example, when the monitoring center receives information about a charging station's relay number and contact oxidation fault, it immediately displays it on the monitoring interface. This ensures timely transmission of abnormal information, enabling operations and maintenance personnel to respond quickly and reducing equipment downtime.

[0039] For example, while saving the location and fault type of an abnormal relay, the alarm log records the specific time of the fault, the device identifier, and the fault type, such as "contact oxidation." These logs are stored in a local database and linked to the in-depth analysis results from the monitoring center. The existence of the log facilitates subsequent fault tracing and ensures a seamless connection between abnormal alarms and equipment operating status analysis, ultimately enabling the precise location of the abnormal relay and the determination of the fault type.

[0040] S103: Process the abnormal information and generate a control instruction, and obtain the encrypted control signal through an encrypted transmission method.

[0041] During specific implementation, the location and fault category information of the abnormal relay are processed through the fault relay isolation switching technology, and the corresponding control instructions are generated for the normally operating relays using the resource occupancy priority sorting rules. The instructions are encrypted using the control signal delay optimization algorithm and the remote instruction encryption transmission protocol to obtain the encrypted control signal data packet.

[0042] Based on the location and fault category information of the abnormal relay, a fault isolation switching method is used to separate the abnormal relay's operating data from the normal operating data. The abnormal relay's location identification and fault classification data are obtained, forming a preliminary abnormal information set. The status data of the normal operating relay is extracted from the abnormal information set. The control requirements of the normal operating relay are sorted according to the resource occupancy priority sorting rules, and the corresponding control instruction set is generated. For this control instruction set, the transmission timing of the instructions is adjusted using a control signal delay optimization method to ensure the stability of instruction transmission. The adjusted instructions are then encrypted using a remote instruction encryption transmission protocol to generate an encrypted control signal data packet. The encrypted control signal data packet is stored in a preset transmission channel for subsequent instruction issuance, ensuring that the processing of the abnormal relay and the control instruction generation process of the normal relay are closely integrated, achieving effective processing of the abnormal relay's location and fault category information and the acquisition of encrypted control signals.

[0043] Specifically, the fault isolation switching method focuses on processing the location and fault classification information of abnormal relays. The key is to separate abnormal data from normal data. For example, if the operating data of a relay in a charging station network becomes abnormal, the fault isolation switching method can quickly separate the operating data of that relay from the overall data stream, forming a separate data set containing the location identifier and fault classification. The advantage of this method is that it prevents abnormal data from interfering with normal equipment operation and provides a clear data foundation for subsequent processing.

[0044] In one embodiment, after extracting the status data of the normally operating relays from the above-mentioned abnormal information set, the application of the resource occupation priority sorting rule is particularly critical.

[0045] For example, among multiple normally operating relays, some may be handling high-priority charging tasks, while others are under low load. Based on the priority sorting rules, control resources can be allocated to the high-load relays first, and corresponding control instruction sets can be generated. This approach ensures the continuity of critical tasks and improves overall operational efficiency.

[0046] For example, control signal delay optimization adjusts the timing of command transmission for a generated set of control instructions. Consider a scenario where network latency is significant, where instructions may not reach the target relay in a timely manner. By optimizing transmission timing, instructions can be ensured to arrive in a reasonable order, avoiding command conflicts caused by latency. Subsequently, the remote command encryption transmission protocol encrypts the instructions, creating an encrypted control signal data packet. This encryption effectively protects the security of the instructions during transmission, preventing external interference or data leakage.

[0047] It should be noted that the encrypted control signal data packet is stored in the preset transmission channel in order to ensure the reliability of the instruction issuance.

[0048] For example, in a multi-device collaboration scenario, encrypted data packets are stored in a unified transmission channel and can be distributed in an orderly manner according to device needs. This approach not only ensures the stability of command transmission but also ensures that the processing of abnormal relays and the generation of control commands for normal relays form a closed loop, improving the coordination of the entire process. Through this series of measures, abnormal relays can be accurately located and classified, while ensuring the secure transmission of control commands.

[0049] S104. Transmit the encrypted control signal to the target device through anti-interference transmission technology, and use a synchronous response mechanism to uniformly schedule multiple devices.

[0050] During specific implementation, the encrypted control signal data packets are transmitted in real time through cross-regional signal transmission anti-interference technology. In response to the emergency stop signal requirements of distributed charging piles, a distributed device synchronization response mechanism and signal transmission reliability verification method are used to uniformly schedule multiple devices to determine whether the signal transmission is completed within the specified time and reaches the target device.

[0051] Using cross-region signal transmission anti-interference technology, control signal packets are encrypted to generate encrypted control signal packets. Orthogonal frequency division multiplexing is used to modulate the encrypted control signal packets, and anti-interference signatures are extracted from the modulated signals to maintain signal integrity during cross-region transmission. The modulated encrypted control signal packets are extracted from the anti-interference signatures, and a distributed device synchronous response mechanism is used to centrally schedule multiple charging piles. Based on a time synchronization protocol, the response time of each charging pile is calibrated to generate a synchronous response time sequence, which is used to determine whether signal transmission is completed within the specified time. The response status of each charging pile is extracted from the synchronous response time sequence, and the arrival of the encrypted control signal packets is verified using a signal transmission reliability verification method. For charging piles that do not receive a signal, the encrypted control signal packets are resent via a backup transmission channel to generate an updated signal arrival status set. The signal reception status of all charging piles is obtained from the signal arrival status set, and the charging piles are coordinated and managed using a hierarchical control instruction execution framework. An emergency stop instruction sequence is generated based on priority sorting rules, and the encrypted control signal packets are distributed to ensure that all target charging piles execute the emergency stop instruction synchronously.

[0052] For example, in the application of anti-interference technology for cross-regional signal transmission, the control signal data packet can be encrypted to ensure that the signal is not tampered with or stolen during long-distance transmission.

[0053] Specifically, the encryption process converts the original control signal data packet into an encrypted one based on a universal symmetric key. Subsequently, the signal is modulated using orthogonal frequency division multiplexing (OFDM). This technology effectively resists multipath interference and noise by dividing the signal into multiple subcarriers for parallel transmission. This processing method ensures high signal transmission quality even in complex environments, laying the foundation for subsequent distributed device scheduling.

[0054] In one embodiment, after extracting the anti-interference characteristic signal from the modulated signal, multiple charging piles can be further uniformly scheduled. The key to the distributed device synchronous response mechanism is to ensure that each device can respond to the control instruction within the same time window.

[0055] For example, by calibrating the clock offsets of each charging station through a time synchronization protocol, a unified, synchronized response time sequence can be generated. This approach helps determine whether signals reach the target device on time, thereby avoiding command execution delays caused by time asynchrony and improving the timeliness of command responses in emergency situations.

[0056] For example, during the signal transmission reliability verification phase, the response status in the synchronous response time series can be analyzed to determine whether the encrypted control signal packet has been successfully delivered. If a charging station is found to have not received the signal, the packet is resent via a backup transmission channel. This backup channel can be based on a different frequency band or a different network path to ensure comprehensive signal coverage. This design provides a reliable alternative in the event of a primary channel failure, ensuring that all devices can receive the command.

[0057] In one embodiment, after obtaining the reception status of each charging station from the updated signal arrival status set, the devices can be coordinated and managed through a hierarchical command execution method. The emergency stop command sequence generated based on the priority sorting rules can ensure that critical equipment responds first.

[0058] For example, among multiple charging stations, the highest-priority device can be stopped first, and then the stop order can be gradually extended to other devices. This step-by-step execution method effectively avoids confusion caused by command conflicts and ensures that the emergency stop command is implemented simultaneously at all target charging stations, significantly improving the coordination and reliability of the overall operation.

[0059] In this step, based on the results of signal transmission, a hierarchical and graded execution framework of control instructions can be used to coordinate and manage the linkage of multiple devices. If a charging pile does not receive the emergency stop signal, the signal is redistributed through the backup transmission channel and the resource allocation anomaly feedback correction system to ensure that all target charging piles have synchronously executed the emergency stop operation instruction.

[0060] Then, the multi-device resource sharing coordination protocol is used to reallocate resources for charging piles that have performed emergency stop operations. A dynamic resource recycling and reuse process is used to integrate idle relay resources. The remote resource allocation authority management module is used to verify the authority of resource allocation, and the optimized relay resource configuration plan is obtained.

[0061] The multi-device resource sharing coordination protocol scans the resource status of charging piles that have undergone an emergency stop operation to obtain data on current resource occupancy and idleness. Based on this scanned data, a dynamic resource recycling and reuse process is used to consolidate idle relay resources and determine a list of resources that can be reallocated. The remote resource allocation permission management module verifies the permissions of this consolidated resource list to determine whether it meets the allocation requirements. If the permission verification passes, the verified resources are reconfigured using a resource allocation optimization algorithm to obtain a preliminary relay resource allocation plan. If the permission verification fails, the backup resource pool access mechanism retrieves backup resource data to determine an alternative resource allocation plan. Based on the preliminary or alternative resource allocation plan, the resource occupancy priority ranking rule is used to evaluate the priority of relay resources and obtain a sorted resource allocation sequence. The sorted resource allocation sequence is then tested for stability using a state prediction analysis model to determine whether the resource allocation meets operational requirements. If the test results indicate an unstable configuration, the relay resource pool dynamic allocation algorithm performs a secondary adjustment of the resources to obtain an optimized relay resource allocation plan. Based on the optimized configuration plan, the allocation instructions are encrypted using the remote command encryption transmission protocol to obtain the final executable control signal data packet.

[0062] Specifically, the multi-device resource sharing coordination protocol scans the resource status of charging piles. A polling mechanism collects relay occupancy data every 5 seconds. If a charging pile is detected to have performed an emergency stop, its relay is marked as recyclable. The dynamic resource recycling process consolidates idle relays and uses a greedy algorithm to select relays that have been idle for more than 30 seconds to generate a list of allocable resources. The remote resource allocation permission management module verifies this list, using a role-based access control (RBAC) model. Allocation is permitted if the requesting party's permission level is ≥ 2. The resource allocation optimization algorithm uses a weighted round-robin strategy to generate a preliminary configuration plan based on the relay's historical load rate (e.g., prioritizes units below 80%). If permission verification fails, the backup resource pool retrieval mechanism selects three backup units from the redundant relay group to generate an alternative plan. The resource occupancy priority ranking rule uses charging pile power (e.g., 120 kW > 60 kW) as a weight to rank the relays in the plan. The state prediction analysis model uses an LSTM algorithm to predict load fluctuations over the next 5 minutes. If the prediction error rate exceeds 15%, the configuration is deemed unstable. A dynamic allocation algorithm for the relay resource pool makes secondary adjustments to unstable configurations, and a genetic algorithm optimizes relay combinations, increasing load balancing to over 90%. Finally, control instructions are encapsulated using the AES-256 encryption protocol, generating data packets with timestamps and digital signatures.

[0063] In the above steps, real-time data collection is performed on the safety relay through the remote command encryption transmission protocol, the contact signal is parsed using the state prediction analysis model, and the equipment operation status is analyzed using the real-time load balancing scheduling mechanism. When an abnormality is detected, an alarm is triggered and the fault diagnosis and positioning is performed. In response to the emergency stop requirements of distributed charging piles, the present invention adopts a distributed equipment synchronization response mechanism and a signal transmission reliability verification method for unified scheduling, and coordinates and manages multiple devices through a hierarchical execution framework of control instructions to ensure that all target charging piles execute emergency stop operations synchronously. The present invention also redistributes resources for the charging piles after stopping through a multi-device resource sharing coordination protocol, thereby realizing real-time monitoring of the charging pile relay status, rapid fault diagnosis, and reliable stop control in emergency situations, thereby improving the safety and reliability of the charging pile system.
