Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of data processing, and in particular to a charging pile emergency stop and reset control method and system. Background Art
[0002] At present, charging piles, as key equipment for electric vehicle energy supplement, have been widely used in public charging stations and residential charging facilities. In the prior art, the emergency stop function of the charging pile is usually implemented through a physical emergency stop button, which is connected to the control module of the charging pile. After pressing the button, the charging circuit is cut off by disconnecting the relay to protect the safety of the equipment and users. Some systems also combine remote monitoring functions, detecting charging anomalies through the background system and sending emergency stop signals. However, in the prior art, the emergency stop process is mostly one-way triggered, and the reset operation requires manually pressing the reset button or remotely executing through the background system. During the entire implementation process, the control logic is relatively simple and relies on the integrity of the physical button or background signal.
[0003] In actual applications, the existing emergency stop reset control method has a key technical defect: the reset operation after the emergency stop lacks accurate detection and feedback of the device status. In actual scenarios, such as public charging stations, when multiple charging piles trigger an emergency stop at the same time, the operator may not be able to quickly confirm whether the device has the reset conditions, which can easily lead to the erroneous execution of the reset operation when the device is still in an abnormal state, thereby causing further failures or even safety hazards.

[0070] The above solution of the present invention includes at least the following beneficial effects:
[0071] The present invention proposes a charging pile emergency stop and reset control method, which significantly solves the problems of insufficient state detection and imperfect feedback in the emergency stop and reset operation in the prior art, and greatly improves the safety, intelligence and user experience of the equipment. In the prior art, sending an emergency stop signal through a physical emergency stop button or a background system can only achieve a simple one-way trigger operation, and the reset process lacks sufficient detection and judgment of the current state of the equipment, resulting in potential safety hazards caused by incorrect reset. The present invention significantly improves the safety, real-time performance and accuracy of the reset operation of the system through a multi-step emergency stop and reset control process.
[0072] First, after receiving the emergency stop trigger signal, the present invention can quickly generate an emergency stop status signal and cut off the main circuit power supply of the charging pile, directly interrupting the charging task and protecting the safety of the equipment and users. In this process, by recording the operating status parameters of the current charging pile, comprehensive real-time data support is provided for subsequent abnormal analysis and reset operations. This parameter recording function is a key improvement that the emergency stop control method in the prior art cannot provide, and can effectively avoid misjudgment caused by lack of abnormal data during the reset process.
[0073] Secondly, the present invention ensures that the judgment of reset conditions is more accurate through multi-level status parameter detection and analysis. For example, by detecting real-time voltage and current, it can directly identify whether the device is in an overload or short-circuit state; by real-time monitoring of the device temperature, it can quickly determine whether there is an overheating risk; the detection of communication status ensures the stability of the connection between the device and the background management system, and further avoids misoperation caused by communication interruption. At the same time, the safety flag provides a clear indication of the current operating status of the device, such as whether it is in an emergency stop state, whether the reset is complete, etc., providing a clear basis for device management.
[0074] In addition, the present invention also introduces a comprehensive reset condition judgment logic, combining a variety of operating parameters for comprehensive analysis to ensure the safety of the reset operation. For example, when the charging pile triggers an emergency stop, the system can accurately determine whether the device meets the reset conditions based on the recorded status parameters and the preset safety threshold. Compared with the prior art method of relying on a physical reset button or direct remote reset by the background system, the present invention significantly reduces the risk of erroneous reset, especially in complex scenarios where multiple charging piles are stopped at the same time. It can effectively avoid resetting the device when it has not returned to a safe state, thereby significantly reducing the possibility of secondary failure of the device.
[0075] The technical advantage of the present invention is that it organically integrates the emergency stop and reset operations, and provides solid technical support for abnormal analysis and judgment of reset conditions through real-time monitoring and recording of status parameters. Compared with the prior art, the present invention not only has higher security, but also greatly improves the user experience through intelligent status feedback and judgment mechanism. For example, in complex scenarios with multiple devices such as public charging stations, the system of the present invention can help operators quickly identify the emergency stop reasons and current operating status of each charging pile, and clearly prompt which devices meet the reset conditions and which devices require further maintenance, thereby significantly improving the efficiency and safety of equipment management.
[0076] In short, the present invention significantly makes up for the defects of the emergency stop reset control method in the prior art, especially in the judgment of equipment reset conditions and state feedback, and completely solves the potential safety hazards caused by insufficient state judgment during reset after emergency stop. At the same time, the present invention provides clear data support for subsequent abnormality investigation and maintenance through comprehensive recording and analysis of the operating status, which not only improves the safety of equipment operation, but also provides users with a more intelligent charging management experience.

[0079] like Figure 1 As shown, an embodiment of the present invention provides a charging pile emergency stop reset control method, the method comprising:
[0080] S100, receiving an emergency stop trigger signal, generating an emergency stop status signal, cutting off the main circuit power supply of the charging pile, and recording the current operating status parameters of the charging pile, wherein the operating status parameters include real-time voltage, current, device temperature, communication status and safety flag, and the safety flag is used to indicate the safety status of the charging pile, including an emergency stop status flag, a fault flag, a circuit protection flag and a reset status flag;
[0081] S200, generating a state data set according to the operating state parameters, and classifying the state data set according to a preset safety threshold group to generate a normal state subset and an abnormal state subset;
[0082] S300, performing multi-dimensional status analysis according to the abnormal status subset, checking the device hardware integrity, analyzing the stability of the communication channel and detecting the integrity of the power supply line, and generating a reset determination parameter set, the reset determination parameter set including a reset permission flag and abnormal location information;
[0083] S400, when the reset permission flag in the reset determination parameter set is prohibited, a reset failure instruction is generated, the reset failure instruction is used to trigger an alarm and generate prompt information, the prompt information includes abnormal parameter data and its location, abnormal impact range and abnormal handling suggestion plan;
[0084] S500: When the reset permission flag in the reset determination parameter set is allowed, a reset confirmation signal is generated, and the reset confirmation signal is used to clear the emergency stop state flag and reset the operating state parameters of the charging pile;
[0085] S600: Execute a reset activation operation according to the reset confirmation signal, generate a reset activation signal, and record the changes in the operating state parameters of the charging pile during the reset process and the final result, and generate state feedback information;
[0086] S700, dynamically monitoring the operating status parameters of the charging pile according to the status feedback information to form monitoring data;
[0087] S800: When abnormal status data is detected in the monitoring data, repeat steps S100 to S700 until the device is in a stable state or enters a manual intervention mode.
[0088] In the embodiment of the present invention, first, after receiving the emergency stop trigger signal, the system can immediately generate an emergency stop state signal and quickly cut off the main circuit power supply, thereby avoiding equipment damage or potential safety accidents caused by the continuous flow of current. This cut-off operation is implemented by combining hardware and software, with extremely high real-time performance, especially when the device is in a high-power working state, it can effectively ensure the safety of the device.
[0089] While the emergency stop status signal is being generated, the system also comprehensively records the operating status parameters of the current device, including real-time voltage, current, device temperature, communication status, and safety flags. These operating status parameters cover the physical operating characteristics of the device, such as voltage, current, and temperature, as well as logical status such as communication connection status and safety flags. Through unified recording, they can provide accurate and detailed data support for subsequent status analysis, exception handling, and reset operations. For example, real-time voltage and current parameters can be used to determine whether there are problems such as short circuits and overloads; device temperature parameters can directly reflect whether the device is at risk of overheating due to overload or increased external ambient temperature; communication status parameters can provide the connection status between the device and the background management system to ensure that abnormal information can be reported in real time; and safety flags provide a clear indication of the overall safety status of the device.
[0090] By recording and monitoring the safety flags, the system can reflect the status of the equipment in real time. For example, the emergency stop status flag indicates that the equipment is currently in emergency stop protection, the circuit protection flag indicates that the equipment has entered the active power-off protection mode, and the reset status flag indicates that the equipment is trying to return to normal operation. These flags not only help the equipment quickly determine the current safety status, but also provide the system with a tool to quickly diagnose the cause of abnormalities. For example, the safety flag can be used to determine whether the emergency stop is triggered by overload or manual operation.
[0091] This series of technical settings significantly improves the emergency handling capabilities of charging piles. For example, when the device is overloaded or in other emergency situations, the main circuit power is cut off while the recorded operating status parameters provide reliable data support for subsequent analysis and reset operations; and the safety flag can accurately identify the current state of the device and provide clear abnormal information to the operator. In complex application scenarios, such as multiple charging piles running in parallel or under high-load conditions, this method greatly improves the safety and reliability of equipment operation through comprehensive monitoring and rapid response to the equipment's operating status.
[0092] Through the method of the present invention, the charging pile can complete the emergency stop operation with a millisecond response in an emergency situation, and based on comprehensive status recording and flag bit analysis, provide a scientific basis for subsequent reset and troubleshooting, thereby significantly improving the stability, reliability and user experience of the equipment.
[0093] More specifically, an emergency stop trigger signal is received, an emergency stop status signal is generated, the main circuit power supply of the charging pile is cut off, and the operating status parameters of the current charging pile are recorded, including:
[0094] The emergency stop trigger signal can be obtained in two main ways. When the user presses the emergency stop button, the charging pile directly captures the signal through the hardware circuit. After the background management system detects an abnormal state, such as overload, overheating, or communication failure, it sends an emergency stop command to the charging pile through the communication module. After the signal is received by the control module of the charging pile, it immediately enters the subsequent processing logic.
[0095] After receiving the emergency stop trigger signal, the control module generates a logical emergency stop status signal. The emergency stop status signal is a logical variable, usually represented by a binary flag, for example, "1" indicates an emergency stop state and "0" indicates a normal state. After the emergency stop status signal is generated, it will be synchronized to the main control unit of the charging pile and trigger the corresponding protection mechanism.
[0096] The control module directly cuts off the main circuit power of the charging pile by driving the circuit breaker or relay, thereby terminating the power supply to the vehicle.
[0097] While cutting off the circuit, the module will also send a signal to the background management system to notify it that the current charging pile has entered the emergency stop state.
[0098] Record the current operating status parameters of the charging pile: In the emergency stop state, the charging pile will record key operating parameters in real time, including the last state before the main circuit is disconnected through the built-in voltage and current sensors. The operating temperature inside the device is obtained through the temperature sensor. Record the current connection status between the charging pile and the background system, such as whether there is a delay or packet loss. Record the status flag of the current device, such as whether it is in an emergency stop state, whether there is a fault, etc. These operating parameters are saved in the storage module of the device and serve as the basis for subsequent abnormal analysis and reset.
[0099] More specifically, according to the status feedback information, the operating status parameters of the charging pile are dynamically monitored to form monitoring data, including:
[0100] Extract key monitoring parameters based on status feedback information and generate initial monitoring parameter data;
[0101] According to the initial data of monitoring parameters, the sampling frequency is adjusted to generate dynamic sampling data;
[0102] Based on the dynamic sampling data, trend analysis is performed to generate trend monitoring data;
[0103] Based on the trend monitoring data, classify the abnormal status and generate abnormal classification data;
[0104] Combine dynamic sampling data and abnormal classification data to generate monitoring data.
[0105] In this embodiment, by dynamically monitoring the operating status parameters of the charging pile, extracting key monitoring parameters in combination with status feedback information, and dynamically adjusting the sampling frequency, it is ensured that abnormal conditions are captured efficiently and accurately; through trend analysis, the parameter change trend is identified in advance, abnormal classification data is generated, the severity of the abnormality is quickly determined, and targeted feedback is provided; finally, the dynamic sampling data and abnormal classification data are integrated to generate comprehensive monitoring data. This method effectively improves the real-time and intelligent level of equipment operating status monitoring, and provides strong technical support for abnormal detection, fault warning, and system optimization.
[0106] In a preferred embodiment of the present invention, a state data set is generated according to the operating state parameters, and the state data set is classified and processed according to the preset safety threshold group to generate a normal state subset and an abnormal state subset, including:
[0107] Extract real-time data and historical data from operating status parameters to generate an initial data set;
[0108] Preprocess the initial data set, filter out invalid data and complete missing parameters to obtain a preprocessed data set;
[0109] Compare the parameters in the preprocessed data set with the preset safety threshold group, and classify the preprocessed data set according to deviations and trends to generate normal state subsets and abnormal state subsets;
[0110] The normal state subset and the abnormal state subset are combined to generate a classified state dataset.
[0111] In an embodiment of the present invention, dynamic classification management of the operating status of the charging pile is achieved by generating a status data set and classifying the status data set according to a preset safety threshold group. In the process of extracting the operating status parameters, real-time data and historical data are combined to make the generated initial data set comprehensive and timely. Real-time data directly reflects the operating status of the current device, while historical data is used to describe the long-term trend and state fluctuations during the operation of the device. For example, when there is a fluctuation in the real-time voltage data, it can be quickly determined whether the fluctuation is an occasional event or a trend problem with long-term risks by comparing it with historical data.
[0112] In the data preprocessing stage, the integrity and availability of the status data are improved by filtering out invalid data and completing missing parameters. For example, when the communication link is interrupted during a certain period of time, resulting in partial data loss, the completion algorithm can complete the data supplement based on historical data and associated parameters; while filtering out invalid data can eliminate abnormal values caused by short-term communication noise or sensor errors, ensuring the reliability of data processing.
[0113] Classification processing further divides the state data set into normal state subsets and abnormal state subsets through deviation analysis and trend analysis of the data. Deviation analysis mainly focuses on the comparison between operating parameters and safety thresholds. For example, when the real-time current exceeds the threshold range, it is directly classified as an abnormal state; trend analysis focuses on the change trend of data within a certain time range, such as identifying potential risk states through historical data fitting and fluctuation amplitude calculation.
[0114] Through this classification processing method, the generated classified status data set has significant technical advantages. The normal status subset can be directly used for continuous monitoring and status display of the equipment, while the abnormal status subset can trigger the system's abnormal response mechanism. Especially in complex operating environments, such as high temperature or unstable power grid conditions, this method can significantly improve the accuracy and response speed of status recognition, thereby improving the overall operating reliability of the charging pile system.
[0115] More specifically, the parameters in the preprocessed data set are compared with the preset safety threshold group, and the preprocessed data set is classified according to the deviation and trend to generate a normal state subset and an abnormal state subset, which specifically include:
[0116] The safety threshold group contains safety ranges set for key operating parameters of the charging pile, such as voltage, current, temperature, communication status, etc.
[0117] The parameters in the preprocessed data set are compared item by item with the preset safety threshold group. If the actual value of a parameter exceeds the threshold, it is judged as abnormal data; otherwise, it is marked as normal data.
[0118] Calculate the relative deviation between the parameter and the threshold, and then determine whether the parameter is abnormal based on the change trend of historical data. For example, use the sliding average method to detect the fluctuation range of the parameter. Based on the analysis results of the deviation and trend, classify the data into a normal state subset and an abnormal state subset. The normal state subset contains all data that meets the safety threshold conditions and has no abnormal trend.
[0119] The abnormal status subset contains all parameter data with excessive deviations or abnormal trends, which is used for subsequent abnormality analysis.
[0120] In a preferred embodiment of the present invention, a multi-dimensional state analysis is performed based on the abnormal state subset to check the device hardware integrity, analyze the stability of the communication channel and detect the integrity of the power supply line, and generate a reset determination parameter set, which includes a reset permission flag and abnormal location information, including:
[0121] Parsing the hardware data in the abnormal state subset to generate hardware state parsing data;
[0122] According to the hardware status analysis data, hardware performance evaluation is performed to generate performance evaluation data;
[0123] Perform packet analysis on the real-time data of the communication channel to obtain channel stability data;
[0124] Generate communication performance evaluation results based on channel stability data combined with communication packet loss rate and delay information;
[0125] Sampling the power supply line data in sections, analyzing the voltage fluctuation and current deviation, and obtaining the power supply analysis results;
[0126] The performance evaluation data, the communication performance evaluation result and the power supply analysis result are combined to generate a reset determination parameter set, wherein the reset determination parameter set includes a reset permission flag and abnormality location data.
[0127] In the embodiment of the present invention, through multi-dimensional analysis of abnormal state subsets, the present invention realizes a comprehensive assessment of the device hardware integrity, communication channel stability and power supply line integrity. The hardware integrity check is based on the analysis of the hardware module data, and can perform detailed analysis on indicators such as module signal strength and connection status. For example, through signal strength detection, it can be identified whether there is a poor module connection or signal attenuation problem; through the module response time analysis, it can be further determined whether the hardware has performance degradation or physical damage.
[0128] Communication channel stability analysis mainly evaluates communication performance indicators such as packet loss rate and transmission delay. For example, when the packet loss rate of a communication module is significantly higher than expected, it can be combined with delay data to determine whether it is caused by signal interference or hardware aging. At the same time, combined with the evaluation of signal strength, it can further distinguish the source of the problem, such as internal module problems of the device or external signal environment problems.
[0129] The power supply line integrity analysis is based on the dynamic sampling of voltage and current data, and can integrate and analyze the fluctuations of the line. For example, by calculating the integral value of voltage fluctuations within a certain period of time, it can be determined whether the line is in a stable state; through the cumulative value of current deviation, it can be further determined whether there is an overload or short circuit risk.
[0130] Combining the above multi-dimensional analysis results, the generated reset judgment parameter set has high reliability and accuracy. The reset permission flag is used to comprehensively reflect whether the system has the reset conditions, and the abnormal location information further points to the specific problem module, thereby providing accurate support for the subsequent recovery operation and maintenance of the system.
[0131] In a preferred embodiment of the present invention, the performance evaluation data, the communication performance evaluation result and the power supply analysis result are combined to generate a reset determination parameter set, wherein the reset determination parameter set includes a reset permission flag and abnormality location data, including:
[0132] Based on the performance evaluation data, the integrity score of the hardware module is calculated and normalized to generate hardware integrity score data;
[0133] According to the communication performance evaluation results, the packet loss rate and delay data in the communication channel stability data are weighted and calculated to generate a comprehensive score for the communication channel;
[0134] According to the power supply analysis results, the current fluctuation parameters and voltage deviation data of the power supply line are jointly analyzed to generate a power supply integrity score;
[0135] The hardware integrity score data, the communication channel comprehensive score and the power supply integrity score are multi-dimensionally weighted to obtain the reset comprehensive score; the calculation formula for the reset comprehensive score is:
[0136] ,
[0137] in, The comprehensive score for reset is Score the hardware integrity, is the comprehensive score of the communication channel, Score the power supply integrity, , and is the weight coefficient;
[0138] , is the total number of hardware modules, For the The actual signal strength of each hardware module, For the The maximum signal strength of each hardware module, For the The weight coefficient of each hardware module;
[0139] , is the packet loss rate of communication data packets, is the average time of communication delay, is a constant used to prevent the denominator from being zero. is the signal quality of the current communication channel, is the maximum signal quality of the communication channel, , and is the weight coefficient;
[0140] , For power supply lines at time The actual voltage, is the reference voltage of the power supply line, For power supply lines at time The actual current, is the reference current of the power supply line, The length of time for integration, which refers to the monitoring period of power supply stability score. is the integral of voltage fluctuation, indicating the cumulative fluctuation of voltage during the monitoring period. is the integral of the current fluctuation, indicating the cumulative fluctuation of the current during the monitoring period;
[0141] Compare the reset comprehensive score with a preset comprehensive score threshold to generate a reset permission flag;
[0142] When the reset comprehensive score is less than the preset comprehensive score threshold, the reset permission flag is allowed, otherwise the reset permission flag is prohibited;
[0143] According to the reset permission judgment data, the abnormal module information in the abnormal state subset is extracted to generate abnormal location data;
[0144] The reset permission judgment data and the abnormality location data are combined to generate a reset judgment parameter set.
[0145] In an embodiment of the present invention, by combining the hardware integrity score, the comprehensive communication channel score and the power supply integrity score, and generating a reset judgment parameter set, the scientificity and accuracy of the reset decision are effectively improved. In terms of hardware integrity scoring, the health status of the hardware modules can be fully quantified by normalizing the signal strength of each hardware module. For example, for the main circuit module, by collecting the signal strength data of the module, such as real-time current or connection signal, after normalization processing, it can accurately reflect whether the module has problems such as poor contact and performance degradation. The normalization setting of the hardware score can not only adapt to the diversity of different types of hardware modules, but also further highlight the importance of key modules in the score by combining weight factors. For example, the score weight of the main power supply module is significantly higher than that of the auxiliary communication module.
[0146] The comprehensive score of the communication channel is completed through weighted calculation of three key indicators: packet loss rate, delay time and signal strength. For example, when the packet loss rate of the communication module exceeds the safety threshold, its comprehensive score will be significantly reduced, and the coordinated evaluation of delay time and signal strength further improves the comprehensiveness and accuracy of the score. This scoring process can reflect the stability of the current communication link and provide a scientific basis for the system to determine whether the device has reliable communication conditions. Especially when the device is in an abnormal state, the communication score can quickly reflect the communication anomalies of the system, such as increased delay or decreased signal strength due to interference.
[0147] The power supply integrity score is calculated by integrating the voltage and current fluctuations, which can accurately reflect the overall stability of the power supply line. For example, by dynamically integrating and analyzing the fluctuation range of voltage and current, the system can determine whether there are persistent instability problems in the power supply line, such as low voltage, short-term power outages, etc. The advantage of this integration setting is that it can capture the long-term fluctuation characteristics of the power supply line, rather than relying solely on short-term peaks or averages, thereby significantly improving the accuracy of the power supply score.
[0148] Finally, through the multi-dimensional weighted combination of hardware integrity score, communication channel comprehensive score and power supply integrity score, the generated reset comprehensive score can fully reflect the overall operating status of the device. The setting of weighting factors ensures the flexibility of the scoring results. For example, when the power supply line score is low, the system can increase the weight of the power supply score to highlight the impact of power supply problems on reset conditions. After comparing the reset comprehensive score with the preset threshold, a reset permission flag is generated, which further clarifies whether the device can be safely reset.
[0149] In addition, the present invention provides a clear basis for problem diagnosis for the system and users through the abnormal location information in the generated reset judgment parameter set. For example, when the scoring result shows that the communication module scores low, the abnormal location information can point to the specific communication module and describe in detail the source of its abnormality, such as signal strength drop or delay time exceeding the standard. This setting can significantly reduce the troubleshooting time of maintenance personnel and improve the efficiency of problem handling.
[0150] In summary, the present invention not only improves the accuracy of reset decisions through multi-dimensional and multi-module comprehensive analysis in reset permission judgment, but also provides comprehensive data support for subsequent problem solving through scoring and positioning, significantly improving the intelligence and safety of the charging pile system.
[0151] In a preferred embodiment of the present invention, when the reset permission flag in the reset determination parameter set is prohibited, a reset failure instruction is generated, and the reset failure instruction is used to trigger an alarm and generate prompt information. The prompt information includes abnormal parameter data and its location, abnormal impact range and abnormal handling suggestions, including:
[0152] When the reset permission flag in the reset determination parameter set is prohibited, abnormal description data is generated according to the abnormal location information, and the abnormal description data includes the deviation range of the abnormal parameters, the module list affected by the abnormality, and the associated risk level;
[0153] According to the abnormal description data, the device protection mode is triggered and the protection mode activation data is generated. The protection mode activation data is used to disconnect the main circuit and stop the operation of non-critical modules;
[0154] Based on the protection mode activation data, the abnormal parameters are analyzed according to the physical coupling of the abnormal parameters and the logical association between the modules to generate the abnormal impact range:
[0155] Combine the exception description data, the protection mode activation data and the exception impact range to generate a reset failure instruction;
[0156] According to the reset failure instruction, a prompt message is generated and uploaded to the background system. The prompt message includes the specific cause of the abnormality, the scope of impact and the proposed solution.
[0157] In an embodiment of the present invention, when the reset permission flag is determined to be prohibited, the present invention can effectively prevent the system from performing unsafe operations without reset conditions by generating a reset failure instruction, thereby further ensuring the safety of the device and users. The abnormal location information is used to generate abnormal description data, clarify the deviation range of the abnormal parameters, the list of modules affected by the abnormality, and the associated risk level. For example, when the communication module of the charging pile has an abnormal signal packet loss rate that is too high, the system can locate the specific communication module through the abnormal description data, and conduct a detailed analysis of the packet loss rate and signal quality of the module to quantify its impact on the overall communication function of the system.
[0158] The triggering of the equipment protection mode is controlled by hardware and software, which quickly disconnects the main circuit to prevent the abnormality from expanding, and stops the operation of non-critical modules, such as pausing the communication module with the background management system to avoid erroneous propagation or repeated transmission of data due to communication abnormalities. On this basis, the impact range of the abnormality is analyzed by combining the physical coupling relationship of the abnormal parameters and the logical association between the modules. For example, when the current fluctuation of the power supply line exceeds the preset threshold and the abnormality is located in the main power supply module, the system will not only mark the module as a fault state, but also further analyze its impact on the main circuit and charging tasks, thereby generating an abnormal impact range score.
[0159] By generating reset failure instructions, the system can provide complete prompt information to users and background systems, including the specific cause of the abnormality, the scope of impact, and recommended processing suggestions. For example, when the scope of the abnormality is small, the prompt information may suggest that the user restart the charging task, while when the scope of impact is large, it is recommended that professionals perform on-site maintenance. Through this setting, the system can actively protect the safety of equipment in abnormal conditions and provide users and maintenance personnel with comprehensive diagnosis and processing basis, thereby significantly improving the intelligence level and operational safety of the system.
[0160] More specifically, when the reset permission flag in the reset determination parameter set is prohibited, the exception description data is generated according to the exception location information. The exception description data includes the deviation range of the exception parameter, the module list affected by the exception, and the associated risk level, specifically including:
[0161] The reset permission flag is set to "prohibited" after comprehensive analysis of the reset determination parameter set. When the system detects a serious anomaly in the hardware module, an unstable communication channel, or an unresolved power supply line problem, the reset permission flag is set to "prohibited".
[0162] The generation of abnormal location information is based on the previous operation parameter analysis and reset comprehensive score.
[0163] The exception description data is a structured exception status report, which includes the following:
[0164] Deviation range of abnormal parameters: By calculating the deviation range between the actual value of the abnormal parameter and its safety threshold, its severity can be clarified. List of modules affected by the abnormality: List all hardware modules affected by the abnormal parameters. For example, if the current fluctuation of the main power supply module is abnormal, the list will include the main power supply module and its directly associated charging control module.
[0165] Associated risk level: The risk level is calculated by combining the degree of deviation of the abnormal parameter and the importance of the affected module. For example, the risk level of an abnormality in the main power supply module will be higher than that of the auxiliary communication module. The risk level is usually divided into multiple levels, such as high, medium, and low.
[0166] More specifically, according to the abnormal description data, the device protection mode is triggered and the protection mode activation data is generated. The protection mode activation data is used to disconnect the main circuit and stop the operation of non-critical modules, including:
[0167] When the abnormal description data clearly indicates the abnormal parameters and affected modules, the system enters the device protection mode. The core function of this mode is to prevent the abnormality from further expanding and protect the operation of other normal modules.
[0168] The conditions that trigger the protection mode include: abnormal fluctuations in the main circuit power supply are detected, which may cause damage to the device. Abnormal temperature rise of the module is detected, which may cause overheating risk. The communication channel is completely interrupted, which may cause information transmission failure.
[0169] The execution of the protection mode includes: cutting off the connection between the main circuit of the charging pile and the external power supply by controlling the relay or circuit breaker to prevent the abnormal state from causing further damage to the vehicle or equipment. Stopping the operation of non-critical modules, which usually include auxiliary communication modules or low-priority hardware modules. By sending a deactivation signal to these modules, the system can reduce the overall load and give priority to protecting the stability of the core modules.
[0170] The protection mode activation data records the detailed information of the current protection status, including: the current timestamp, the status flag of disconnecting the main circuit, the list of non-critical modules that have been stopped, and the activation flag of the system protection mode.
[0171] More specifically, based on the protection mode activation data, the abnormal parameters are analyzed according to the physical coupling of the abnormal parameters and the logical association between the modules to generate the abnormal impact range, including:
[0172] After entering the protection mode, the device generates protection mode activation data to clarify the initial impact of the current anomaly.
[0173] Physical coupling refers to how abnormal parameters directly affect other modules through physical connections. The analysis of physical coupling focuses on the following aspects:
[0174] Coupling in the circuit: If the voltage of the main circuit fluctuates abnormally, such as being too high or too low, it may directly affect other connected modules, such as the control module or the charging interface module, through the power supply line.
[0175] By analyzing the current distribution of the main circuit, the modules directly connected to the abnormal module circuit are identified. For example, the modules upstream of the circuit may be affected by voltage fluctuations, and the downstream modules may face power shortage problems.
[0176] Thermal coupling: If a module overheats due to overload or failure, it may affect adjacent modules through heat conduction. For example, overheating of the main power module may affect the control module or communication module next to it.
[0177] Signal coupling: If the communication module is interrupted due to signal interference, it may cause the adjacent modules to be unable to receive instructions or send feedback normally. For example, an abnormal communication module may prevent the status of the charging interface module from being uploaded to the backend in real time.
[0178] The core of physical coupling analysis is to determine which modules are directly affected by abnormal parameters through physical connections. These directly affected modules will be marked as modules directly related to the abnormality.
[0179] In addition to physical coupling, there are also logical connections between modules, especially in system-level operation. For example, an abnormality in one module may indirectly affect the operation of other modules through logical dependencies. The key points of logical connection analysis include:
[0180] Data dependency: If the abnormal module is responsible for the collection or transmission of key data, other modules that rely on the data may be affected. For example, the interruption of the communication module may cause the background to be unable to obtain the operating status data of the device, thereby affecting the background control of other modules.
[0181] Functional dependency: If the function of the abnormal module is a prerequisite for the normal operation of other modules, other modules may be functionally restricted. For example, the abnormality of the main circuit module will directly limit the power supply function of the charging interface module.
[0182] Control logic dependency: Some modules are closely related to other modules through control logic. For example, the output voltage of the charging module needs to match the input requirements of the battery module. If the voltage of the charging module is abnormal, the battery module may not operate normally.
[0183] Logical association analysis identifies modules that may be indirectly affected by abnormal modules by sorting out the dependencies between modules.
[0184] Based on the analysis results of the above physical coupling and logical association, the system will generate an abnormal impact range to clarify the potential impact of the current abnormal state on the entire system.
[0185] Definition of abnormal impact range: The abnormal impact range refers to all modules that have direct or indirect relationship with the current abnormal parameters and modules, including:
[0186] Directly affected modules: modules that are directly affected by the abnormality through physical coupling. For example, a main circuit abnormality may directly affect the power supply module and the control module.
[0187] Indirectly affected modules: modules that may be indirectly affected through logical associations. For example, an abnormality in the communication module may indirectly cause the background to be unable to obtain status, thereby affecting the remote control module.
[0188] The impact range of the exception is usually presented in the form of a module list. For example:
[0189] Abnormal parameters: main circuit voltage fluctuation;
[0190] Directly affected modules: main power supply module, auxiliary power supply module;
[0191] Indirect impact modules: charging interface module, communication module, and background management module.
[0192] Clarify which modules are potentially affected by the current abnormal state, and provide a basis for subsequent abnormal processing and reset operations. Help the system formulate targeted protection strategies. For example, directly affected modules are processed first, and indirectly affected modules are monitored or isolated as needed.
[0193] Through physical coupling analysis and logical association analysis, the abnormal impact range can comprehensively cover the direct and indirect impact modules of abnormal parameters. The determination of the abnormal impact range provides clear module-level information for the system's abnormal processing flow, ensuring the accuracy and comprehensiveness of the processing process. In this way, the present invention can achieve efficient analysis and processing of abnormal states, providing solid protection for the safe operation of equipment.
[0194] More specifically, according to the reset failure instruction, a prompt message is generated and uploaded to the background system. The prompt message includes the specific cause of the abnormality, the scope of impact and the proposed solution, including:
[0195] Generate prompt information, which needs to cover the following content:
[0196] Specific cause of the abnormality: Through the analysis of abnormal description data and impact range, the source of the abnormality can be identified, such as excessive current deviation of the main power supply module.
[0197] Impact: List all affected modules.
[0198] Suggested solutions: If the abnormality affects a small area, the prompt message may suggest resetting the local module. If the abnormality affects a large area, the prompt message may suggest suspending the use of the device and having it checked by a professional.
[0199] The prompt information contains the following fields: abnormal parameter name and deviation range. List of affected modules. Risk level and impact range. Recommended operation steps, such as power off maintenance, module replacement, etc.
[0200] The prompt information is uploaded to the backend system through the communication module for remote monitoring and management by operation and maintenance personnel. The data submitted to the backend is usually in JSON or XML format, including detailed information such as timestamp, device ID, abnormal data, etc.
[0201] In a preferred embodiment of the present invention, when the reset permission flag in the reset determination parameter set is allowed, a reset confirmation signal is generated, and the reset confirmation signal is used to clear the emergency stop state flag and reset the operating state parameters of the charging pile, including:
[0202] According to the reset judgment parameter set, the emergency stop state information of the equipment is extracted, and the emergency stop state clearing data is generated, and the clearing data includes the key state parameters before the equipment is reset;
[0203] Clear data according to the emergency stop status, trigger the equipment status initialization module, and obtain the initialization status data;
[0204] Based on the initialization state data, the running state parameters are reset and a consistency check is performed to obtain the state consistency score: The calculation formula for the state consistency score is:
[0205] ,
[0206] in, Score the state consistency, For the The actual value of the parameter after reset. For the The reference value of the parameter, is the total number of state parameters, For the The weight coefficient of each parameter;
[0207] When the state consistency score is less than a preset consistency score threshold, operation state reset data is generated and combined with a reset determination parameter set to generate a reset confirmation signal.
[0208] In an embodiment of the present invention, when the reset permission flag is allowed, the present invention realizes the comprehensive clearing of the emergency stop state of the device and the resetting of the operating state by generating a reset confirmation signal. The emergency stop state information in the reset determination parameter set includes key operating parameters of the device before entering the emergency stop state, such as the real-time voltage and current of the main circuit and the temperature state of the device. This information is completely extracted when generating the emergency stop state clearing data, and combined with the subsequent state initialization operation to ensure that the device can be restored to a safe initial state during the reset process.
[0209] The device status initialization module is implemented jointly by software and hardware. During the generation of the initialization status data, the system can perform consistency checks on the reset parameters to ensure that the deviation between the reset parameters and the reference values is within a safe range. For example, when the current value of the main circuit fluctuates slightly after reset, the system can calculate through the consistency check formula to determine whether the fluctuation is within a reasonable range. The consistency score quantifies the reset effect of the operating status parameters. By calculating the deviation of each parameter and weighted summing them, the generated score intuitively reflects the degree of recovery of the parameters after reset. If the consistency score exceeds the preset threshold, the operating status reset data is generated, and the final reset confirmation signal is generated in combination with the reset judgment parameter set.
[0210] The technical effect of this setting is that, through the quantitative analysis of the state consistency score, the system can evaluate the recovery of parameters in real time during the reset process, and make timely adjustments when abnormalities are found to avoid further expansion of potential problems. The generation of the reset confirmation signal marks the completion of the reset operation, providing a clear status basis for the next operation of the equipment. At the same time, by logging the key operations and parameter changes during the reset process, the system can provide detailed data support for subsequent monitoring and maintenance, significantly improving the intelligence level of system operation and the reliability of operation.
[0211] More specifically, according to the reset determination parameter set, the emergency stop state information of the equipment is extracted to generate emergency stop state clearing data, which includes key state parameters before the equipment is reset, including:
[0212] The system analyzes the reset determination parameter set to extract key information when the device enters the emergency stop state, such as: the cause of the emergency stop trigger, such as overload, overheating, short circuit, etc., abnormal modules and their related parameters.
[0213] The extraction of emergency stop status information is to select relevant key parameters from the recorded operating status parameters to ensure that the status data before the device is reset is accurately captured. These parameters include: the voltage and current values of the main circuit during emergency stop. The temperature status of the device during emergency stop, reflecting whether the device has overheating risks. Whether there is communication interruption or channel instability. The flag bit records whether the emergency stop is manually triggered by the user or automatically triggered by the device protection logic.
[0214] Emergency stop state clearing data is a structured data used to indicate the running state of the device before it enters the emergency stop state, providing a basis for subsequent reset. Clearing data includes: key parameter records before the emergency stop state is triggered, such as real-time voltage, current, module status, etc. Specifically indicate which modules or parameters cause the emergency stop to be triggered. Record the time point of the emergency stop trigger for subsequent analysis.
[0215] By generating emergency stop status clear data, the system can refer to the original state of the device during the reset process, avoiding erroneous reset operations caused by missing status information.
[0216] More specifically, according to the emergency stop status clearing data, the equipment status initialization module is triggered to obtain the initialization status data, which specifically includes:
[0217] After receiving the emergency stop status clearing data, the initialization module starts to perform the status initialization operation before resetting.
[0218] The core purpose of initialization is to clear the logical flags and historical abnormal states generated by the device in the emergency stop state, so that the device can return to the default initial operating state.
[0219] Perform status detection on the main circuit module to ensure that the main circuit resumes normal operation. For example, by detecting whether the voltage and current have returned to the normal range, confirm that the circuit is ready to be re-powered. Perform a soft reset on non-critical modules, such as communication modules and auxiliary equipment modules, to clear their internal fault status flags. Reset logical flags such as the emergency stop status flag and the safety protection flag to ensure that the logical state of the device is consistent with the physical state. If the charging pile has unfinished tasks before the emergency stop, such as an unfinished charging process, the initialization module will clear the task queue to ensure that the device is in an idle state. Clean up non-persistent data in the storage unit, such as temporary data or cache files recorded during the emergency stop process.
[0220] Initialization status data is a snapshot of the device's status after initialization is completed, used to verify whether the device has the reset condition. It includes: main circuit status, that is, whether it is powered on. Connection status and signal strength of each module. Current value of the security flag, that is, whether it has been cleared. Initialization completion timestamp.
[0221] By triggering the status initialization module, the system can clear the abnormal status generated during the emergency stop process and generate initialization status data to provide support for subsequent reset confirmation. Generate operating status reset data:
[0222] More specifically, when the state consistency score is less than a preset consistency score threshold, the operation state reset data is generated and combined with the reset determination parameter set to generate a reset confirmation signal, specifically including:
[0223] The state consistency score is compared with a preset consistency score threshold. When the state consistency score is less than the preset consistency score threshold, the operation state reset data is generated based on the state consistency score. The operation state reset data includes:
[0224] Parameters with large deviations and their adjustment targets. For example, the target value of the main circuit voltage may be 220V, but the voltage is 200V after initialization, then the operation status reset data will recommend adjustment to the target value. Based on the degree of deviation and parameter weight, the adjustment order of the parameters is generated.
[0225] After the state consistency score meets the threshold condition, the operation state reset data is combined with the reset judgment parameter set to generate the final reset confirmation signal. The reset confirmation signal includes: the current state of the device. The status flags of each module, such as the main circuit is powered on and the communication module has been restored. Confirmation that the device has met the reset conditions.
[0226] By judging the state consistency score and generating the operation state reset data, the operation state of the equipment can be dynamically adjusted to ensure that the equipment meets the consistency requirements before resetting. The generation of the reset confirmation signal indicates that the equipment is ready to enter the normal operation state, providing a clear condition guarantee for the completion of the reset operation.
[0227] In a preferred embodiment of the present invention, according to the reset confirmation signal, a reset activation operation is performed to generate a reset activation signal, and at the same time, the changes in the operating state parameters of the charging pile during the reset process and the final results are recorded to generate state feedback information, including:
[0228] According to the reset confirmation signal, the main circuit is restored in sequence to generate main circuit restoration data;
[0229] According to the main circuit recovery data, start the equipment hardware self-test program and generate hardware self-test data;
[0230] Based on the hardware self-test data, the real-time monitoring module is activated to generate initial monitoring data;
[0231] Combine the main circuit recovery data, hardware self-test data and monitoring initial data to generate a reset activation signal;
[0232] During the reset process, the operating status parameters are dynamically collected and recorded to generate a reset process log;
[0233] After the reset is completed, status feedback information is generated based on the reset process log.
[0234] In an embodiment of the present invention, after the reset confirmation signal is generated, the present invention completes the full recovery of the device by performing a reset activation operation. The recovery of the main circuit is a key step in the reset activation. By performing real-time detection of state parameters such as current and signal on the main circuit, the system can ensure the safety of the circuit recovery. For example, during the recovery of the main circuit, the change trend of the current is monitored in real time, and the fluctuation integral is used to determine whether the current is stable within the target range, thereby ensuring the output stability after the circuit is restored.
[0235] The start of the hardware self-test program further verifies the operating status of each module after the device is reset. The self-test program covers key indicators such as the connection status of the hardware module and the signal feedback strength. By collecting and analyzing these data in real time, the system can determine whether there are potential problems with the hardware module. For example, during the self-test process, if the signal feedback strength of a module is lower than the threshold, the system can mark the module as sub-healthy and record its specific status in the status feedback information to provide a basis for subsequent maintenance.
[0236] The activation of the real-time monitoring module enables the system to dynamically collect operating status parameters during the reset process and generate a reset process log. The log includes the recovery time, parameter change trend, and final recovery status of each module. For example, when the recovery time of a module is significantly higher than the average level, the log record can provide support for analyzing potential performance issues of the module. After the reset is completed, the system generates status feedback information based on the log and monitoring data, which fully describes the current operating status of the device.
[0237] The technical effect of this setting is that, through the dynamic collection and comprehensive recording of the reset process, the system can fully grasp the execution process and results of the reset operation, thereby ensuring the safety and reliability of the equipment after the reset. At the same time, through the generation of status feedback information, the system can provide users and maintenance personnel with intuitive equipment operation status reports, further improving the intelligence of the equipment and user experience.
[0238] More specifically, according to the reset confirmation signal, the main circuit is restored in sequence to generate the main circuit restoration data, which specifically includes:
[0239] The reset confirmation signal indicates that the device has completed state initialization and meets the reset conditions. It is a trigger signal for the device to enter the main circuit and resume operation.
[0240] First, the control module activates the circuit breaker or relay in the main circuit by sending instructions to restore the connection between the main circuit and the power supply system.
[0241] During the circuit restoration process, circuit parameters such as current and voltage are monitored in real time to ensure that no overload or short circuit occurs during the restoration process.
[0242] During the recovery process, if abnormal voltage or current fluctuations are detected, such as exceeding the preset safety threshold, the system will immediately interrupt the recovery of the main circuit and generate relevant abnormal information. Parameters such as voltage, current, and power need to be recorded in real time during the recovery process to ensure that the circuit operation is restored and stable.
[0243] The main circuit recovery data records the core information of the main circuit recovery process, including: the change trend of circuit parameters such as voltage and current, the recovery completion timestamp, whether there are abnormal conditions, and the identification of the abnormal module.
[0244] The data format is usually structured data, such as JSON or XML format, so that subsequent modules can call it. Through the generation of main circuit recovery data, the system can accurately record the entire process from disconnection to normal operation of the main circuit, providing a reliable data basis for the startup and monitoring of subsequent modules.
[0245] More specifically, according to the main circuit recovery data, the device hardware self-test program is started to generate hardware self-test data, including:
[0246] When the main circuit is restored and the circuit parameters are stable, the system automatically starts the hardware self-test program.
[0247] The purpose of hardware self-test is to check whether each hardware module has resumed normal working state after reset and to identify potential hardware failures.
[0248] Module connection status detection: Check whether the signal connection between each hardware module is normal, for example, whether there is loss or delay in the signal transmission between the sensor and the control module.
[0249] Signal Strength Analysis: Measures the output signal strength of each module and compares it with a reference value.
[0250] Functional test: Verify the core functions of the module. For example, the main power supply module tests its power supply capability, and the communication module tests its data packet receiving and sending capability.
[0251] The hardware self-test data is a comprehensive diagnostic report, including: status flags, signal strength of each module, hardware integrity score. The self-test data will be saved in real time and uploaded to the backend management system for remote diagnosis.
[0252] The generation of hardware self-test data ensures that all modules are in a usable state after the device is reset. If a problem module is found, it can be marked in time and the subsequent exception handling process can be triggered.
[0253] More specifically, based on the hardware self-test data, the real-time monitoring module is activated to generate initial monitoring data, including:
