Description

Technical Field

[0001] This invention relates to the field of yacht electronic control and scheduling technology, and in particular to a yacht electronic control intelligent scheduling method and system based on a multi-sensor linkage feedback mechanism. Background Technology

[0002] The intelligent scheduling process of yacht electrical control is realized through a marine charging control box. This box features a fully sealed design made of 306 stainless steel. The connection and disconnection of the loads within the box are controlled by modern automotive-grade DC contactors. Overload protection for the loads is provided by high-voltage DC fuses, replacing the existing DC air switches. Operation is controlled by a central controller, avoiding frequent opening and closing of electrical control operations. The specific implementation process is as follows: After the lithium battery in the marine charging control box is connected, the host computer starts, triggering the display of the status of all fuses. The main PLC (Programmable Logic Controller)... The main PLC (Programmable Logic Controller) and the auxiliary PLC operate in parallel after being powered on. The main PLC, upon powering on, sends real-time communication data to the system and displays the status of all fuses (summarizing fuse information from the main and auxiliary PLCs and the system). The auxiliary PLC, upon powering on, sends real-time communication data to the system (such as the speed of the port and starboard main motors, remaining battery power, battery temperature, etc.). After both the main and auxiliary PLCs are powered on, they first check the battery fuse status. If an abnormality is detected, a buzzer sounds and the host computer displays a fault. If normal, they continue to check if the battery can be connected. If an abnormality is detected, a buzzer sounds and the host computer displays a fault. If normal, the battery contactor actuates, the battery outputs voltage, and insulation is tested. If insulation is detected as abnormal, a buzzer sounds and the host computer displays a fault. If insulation is normal, they check the inverter fuse status. If an abnormality is detected, a buzzer sounds and the host computer displays a fault. If normal, they sequentially complete the inverter start button and bus tie contactor actuation, as well as the inverter contactor process. The inverter then runs and outputs data, displaying the inverter's output.

[0003] The existing charging control process is as follows: First, the AC power is converted into DC power output through the charging system. Then, the control center receives and adjusts the current and voltage feedback from the charging system. Finally, the current operating parameters are visualized, and charging parameters, such as the charging time, are set and adjusted through the control center (central controller).

[0004] For example, the Chinese invention patent with announcement number CN103558828B discloses a ship group monitoring system based on mobile communication and satellite positioning. This system includes a shipborne terminal installed on the hull, with the electronic system using solar panels to charge lithium batteries and backup batteries; real-time storage of the ship's GPS information, and the use of communication units to return information such as GPS, alarms, and shipborne terminal status to the group monitoring center; and the monitoring center's software service platform combined with a GIS system to provide intuitive display and unified management of the monitored vessels.

[0005] For example, Chinese invention patent CN118192333A discloses a dedicated communication control device and control method for unmanned vessels, including: a controller, an interface module for receiving and forwarding CAN data; a protocol conversion module for converting control signals from the controller into control data of a preset protocol; a data acquisition module for acquiring battery data of the unmanned vessel in real time through built-in sensors; a controller for performing logical processing on the acquired battery data and issuing corresponding control signals based on the processing results; and a communication module for forwarding the control signals to an external ground monitoring station.

[0006] The above-mentioned technology has at least the following technical problems: The connection and disconnection of the load in the marine charging control box are controlled by modern automotive-grade DC contactors. When the yacht is continuously and violently rocking, the power supply lines between the main PLC and auxiliary PLC and the storage battery may experience frequent voltage fluctuations, interfering with the stability of the power supply between the main PLC and auxiliary PLC and the storage battery. This leads to unstable operation of the main PLC and auxiliary PLC, further interfering with the control signal transmission of the battery contactor. As a result, there is a delay in the action of the battery contactor based on the control commands transmitted by the main PLC and auxiliary PLC. Consequently, the real-time information exchange between the yacht's central controller and the marine charging control box is not timely during the charging process, resulting in inaccurate setting and adjustment of charging parameters by the central controller and low timeliness of intelligent scheduling of the yacht's electronic control system. Summary of the Invention

[0007] To address the technical problem of low timeliness in existing yacht electronic control intelligent scheduling technologies, this invention provides a yacht electronic control intelligent scheduling method and system based on a multi-sensor linkage feedback mechanism. The technical solution is as follows: On the one hand, a yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism is provided, including: during the multi-sensor linkage feedback process of the marine charging control box, a yacht operation interference assessment is performed to generate a yacht operation interference assessment result; based on the yacht operation interference assessment result, it is determined whether to perform a yacht power supply stability assessment; if the yacht power supply stability assessment is not performed, a yacht electronic control qualified prompt is sent; otherwise, based on the yacht power supply stability assessment result, it is determined whether to perform yacht power supply stability optimization, which means improving the smoothness of the yacht charging and discharging processes by setting the charging time and discharging time; after the yacht power supply stability assessment is qualified, a power-on operation stability assessment is performed to generate a power-on operation stability assessment result; based on the power-on operation stability assessment result, it is determined whether to perform power-on operation stability optimization, which means improving the stability of the power-on operation voltage by setting the charging voltage and charging current; after the power-on operation stability assessment is qualified, a battery contactor signal qualified assessment is performed to generate a battery contactor signal qualified assessment result.

[0008] On the other hand, a yacht electronic control intelligent scheduling system based on a multi-sensor linkage feedback mechanism is provided, applying a method for yacht electronic control intelligent scheduling based on a multi-sensor linkage feedback mechanism, including: a yacht operation interference monitoring module, a yacht power supply stability optimization judgment module, a powered operation stability optimization judgment module, and a battery contactor signal qualification monitoring module; wherein, the yacht operation interference monitoring module is used to perform yacht operation interference assessment during the multi-sensor linkage feedback process of the marine charging control box to generate a yacht operation interference assessment result, and determines whether to perform a yacht power supply stability assessment based on the yacht operation interference assessment result; the yacht power supply stability optimization judgment module is used to send a yacht electronic control qualification prompt if no yacht power supply stability assessment is performed, otherwise it determines whether to perform yacht power supply stability optimization based on the yacht power supply stability assessment result; the powered operation stability optimization judgment module is used to perform a powered operation stability assessment after the yacht power supply stability assessment is qualified to generate a powered operation stability assessment result, and determines whether to perform powered operation stability optimization based on the powered operation stability assessment result; the battery contactor signal qualification monitoring module is used to perform a battery contactor signal qualification assessment after the powered operation stability assessment is qualified to generate a battery contactor signal qualification assessment result.

[0009] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention include at least: 1. By conducting yacht operation interference assessment and determining whether to conduct yacht power supply stability assessment based on the assessment results, it helps reduce redundant computing resource consumption. If yacht power supply stability assessment is not conducted, a yacht electronic control qualification prompt is sent; otherwise, determining whether to optimize yacht power supply stability based on the assessment results helps achieve graded control of power supply stability and reduces the possibility of adjustment lag. After the yacht power supply stability assessment is qualified, a power-on operation stability assessment is conducted and it is determined whether to optimize power-on operation stability. This helps achieve coordinated control, thereby avoiding overcharging or undercharging caused by single-parameter adjustment, and helps improve the degree of optimization qualification, thus achieving precise control of energy conversion. After the power-on operation stability assessment is qualified, a battery contactor signal qualification assessment is conducted and it is determined whether to conduct control interaction delay assessment. This helps enhance the PLC's anti-interference capability and avoid insufficient anti-interference capability due to signal loss. This improves the timeliness of intelligent scheduling of yacht electronic control and solves the problem of low timeliness of intelligent scheduling of yacht electronic control caused by PLC power-on operation stability interference in existing technologies.

[0010] 2. By processing the stable power-on operation data through harmonic averaging, a stable power-on operation index is obtained. Compared with existing technologies that quantify the stability of the main PLC and auxiliary PLC power-on operation based on a single dimension, the harmonic averaging method, which is more sensitive to extreme values, helps to ensure the uniformity of the power-on operation data dimensions. This avoids weight imbalance caused by differences in dimensions and charging false protection due to transient interference. Based on the stable power-on operation index, it helps to determine whether the stable power-on operation conditions are met, which helps to shorten the fault diagnosis path and thus improve the response speed of yacht charging control.

[0011] 3. By harmonic averaging the control interaction delay data to obtain the control interaction delay score, compared to the existing technology that only evaluates the delay of real-time information interaction between the yacht's central controller and the marine charging control box, the harmonic averaging amplifies the impact of the real-time information interaction delay, compressing multi-dimensional and multi-frequency interaction delay data into a single comprehensive score. This helps reduce the risk of instantaneous communication. By judging whether the control interaction delay score meets the control interaction qualification conditions, and sending a control interaction qualification prompt when the control interaction delay score meets the control interaction qualification conditions, the charging safety control is upgraded from passive response to active prevention, which helps to suppress delay deterioration and ensure the safety of yacht charging.

[0017] In the embodiments of the present invention, sometimes a subscript such as W1 may be written as a non-subscript such as W1. When the difference is not emphasized, the meanings to be expressed are the same.

[0018] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0019] This invention provides a method for intelligent scheduling of yacht electronic control systems based on a multi-sensor linkage feedback mechanism. For example... Figure 1 The flowchart shown is for a yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism. The processing flow of this method may include the following steps: Priority is given to yacht operation interference monitoring: During the multi-sensor linkage feedback process of the marine charging control box, yacht operation interference assessment is conducted to generate yacht operation interference assessment results. Based on the yacht operation interference assessment results, it is determined whether to conduct a yacht power supply stability assessment. By conducting yacht operation interference monitoring, it is helpful to capture various interference factors during yacht operation, such as the impact of strong wind interference on the yacht's power and power supply stability. This helps to accurately grasp the yacht operation interference situation and thus improve the safety of yacht intelligent control.

[0020] Secondly, the yacht power supply stability optimization judgment: If the yacht power supply stability assessment is not performed, a yacht electronic control qualified prompt will be sent; otherwise, the yacht power supply stability optimization will be judged based on the yacht power supply stability assessment results. Yacht power supply stability optimization means improving the smoothness of the yacht charging and discharging process by setting the charging and discharging time. By judging the yacht power supply stability, it is helpful to discover problems in the power supply in a timely manner, such as voltage fluctuations and frequency deviations, so as to avoid damage to the yacht or abnormal operation due to power supply problems.

[0021] Next, the power supply stability optimization is determined: After the yacht's power supply stability assessment is passed, a power supply stability assessment is conducted to generate a power supply stability assessment result. Based on the power supply stability assessment result, it is determined whether power supply stability optimization should be performed. Power supply stability optimization means improving the stability of the power supply voltage by setting the charging voltage and charging current. By determining the power supply stability optimization, it is helpful to accurately set the charging voltage and charging current, which can provide a stable power input to the yacht and reduce equipment failures, data loss and other problems caused by voltage fluctuations.

[0022] Finally, battery contactor signal qualification monitoring: After the power-on operation stability assessment is passed, the battery contactor signal qualification assessment is performed to generate the battery contactor signal qualification assessment result; by performing battery contactor signal qualification monitoring, it is helpful to improve the timeliness of battery contactor response, thereby improving the timeliness of yacht electronic control intelligent scheduling and preventing safety accidents such as battery overcharging, over-discharging, and short circuit.

[0023] Before designing the yacht electronic control intelligent scheduling method based on multi-sensor linkage feedback mechanism provided in this application, a database storing various setting data is established. The database includes, but is not limited to, preset main PLC-battery power supply stability value and preset auxiliary PLC-battery power supply stability value, etc., and the various values ​​are directly set by technical personnel.

[0024] like Figure 2 The diagram shown is a general overview of the yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism provided in this embodiment of the invention. Figure 2 It can be seen that: yacht operation fluctuation interference indicators are obtained through yacht operation interference monitoring. When the monitored yacht operation fluctuation interference indicators meet the yacht fluctuation conditions, a yacht electronic control qualified prompt is sent; otherwise, the main and auxiliary PLC coordinated stability deviation value is obtained through yacht power supply stability optimization judgment. When the monitored main and auxiliary PLC coordinated stability deviation value does not meet the yacht power supply stability conditions, yacht power supply stability optimization is performed. Yacht power supply stability optimization means setting both charging time and discharging time simultaneously. Conversely, power-on operation stability indicators are obtained through power-on operation stability optimization judgment. When the monitored power-on operation stability indicators do not meet the power-on operation stability conditions, power-on operation stability optimization is performed. Power-on operation stability optimization means setting both charging voltage and charging current simultaneously. Conversely, battery contactor signal qualification monitoring is used. When the monitored battery contactor signal transmission qualification value is not greater than the preset signal transmission qualification value obtained from the database, control interaction delay evaluation is performed; otherwise, battery contactor signal transmission optimization is performed. Battery contactor signal transmission optimization means setting both the main PLC scan cycle and the auxiliary PLC scan cycle simultaneously.

[0025] In this embodiment, the yacht operation interference monitoring, yacht power supply stability optimization judgment, power-on operation stability optimization judgment, and battery contactor signal qualification monitoring are interconnected and mutually supportive. The yacht operation interference monitoring provides operating status information, the yacht power supply stability optimization judgment focuses on the performance of the power supply, the power-on operation stability optimization judgment focuses on the working status of the main PLC and auxiliary PLC after power-on, and the battery contactor signal qualification monitoring ensures the safety and reliability of the charging process. This improves the accuracy and timeliness of feedback and interaction between the marine charging control box and the yacht central controller. Each link is progressive and works together to provide comprehensive protection for the safe and stable operation of the yacht.

[0026] Furthermore, a yacht operation interference assessment is conducted to generate a yacht operation interference assessment result. Based on the yacht operation interference assessment result, it is determined whether to conduct a yacht power supply stability assessment. The specific process is as follows: The yacht operation fluctuation interference index is obtained by harmonic averaging the yacht voltage anomaly and the yacht voltage fluctuation anomaly, which is used to measure the power supply interference situation of the yacht in strong wind areas. If the yacht operation fluctuation interference index meets the yacht fluctuation conditions, a yacht electrical control qualified prompt is sent; otherwise, a yacht power supply stability assessment is conducted. Since the yacht voltage anomaly and the yacht voltage fluctuation anomaly are interrelated and mutually influential, when the yacht is running in a strong wind area, the power supply interference situation of the yacht in a strong wind area can be assessed by using both. This allows for a comprehensive consideration of the persistence and intensity of the interference, and a comprehensive characterization of the power supply interference from the two key dimensions of duration and fluctuation amplitude, which helps to obtain the actual situation of power supply interference.

[0027] Among them, the continuous abnormal value of yacht voltage is represented by the ratio of the maximum duration monitored by the timer when the yacht voltage fluctuation deviation is greater than the preset yacht voltage fluctuation deviation to the maximum preset duration. The ratio quantification means that a ratio calculation is performed. The abnormal value of yacht voltage fluctuation is represented by the ratio quantification of the yacht voltage fluctuation deviation and the preset yacht voltage fluctuation deviation. The voltage of the power supply bus at the preset point of the power supply bus within the preset time period is monitored by the voltage sensor, and its maximum and minimum values ​​are counted. The difference between them is taken as the yacht voltage fluctuation deviation. The yacht fluctuation condition means that the yacht operation fluctuation interference index is not greater than the preset yacht operation fluctuation interference index obtained from the database. The preset yacht operation fluctuation interference index is represented by the average value of the yacht operation fluctuation interference index over the historical time period.

[0028] like Figure 3 The diagram shown illustrates the optimization of yacht power supply stability using a yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism, as provided in an embodiment of the present invention. Figure 3 It can be seen that when the monitored stability deviation value of the main and auxiliary PLCs meets the stable power supply conditions of the yacht, a power-on operation stability assessment is performed; otherwise, the yacht power supply stability is optimized. The yacht power supply stability optimization includes setting the charging time and discharging time simultaneously. The charging time setting uses a preset charging time adjustment ratio as the adjustment step size for the single charging time, gradually increasing the single charging time. The discharging time setting uses a preset discharging time adjustment ratio as the adjustment step size for the single discharging time, gradually increasing the single discharging time.

[0029] Specifically, the process for determining whether to optimize yacht power supply stability based on the yacht power supply stability assessment results is as follows: The degree of deviation between the obtained yacht power supply stability score and the preset yacht power supply stability score obtained from the database is quantified to obtain the corresponding yacht power supply stability deviation value. This deviation value is then harmonic-averaged to obtain the main and auxiliary PLC collaborative stability deviation value. The yacht power supply stability deviation value includes the main PLC-power supply stability deviation value and the auxiliary PLC-power supply stability deviation value. A judgment is made based on the main and auxiliary PLC collaborative stability deviation value. If the main and auxiliary PLC collaborative stability deviation value meets the yacht power supply stability conditions, a power-on operation stability assessment is performed; otherwise, yacht power supply stability optimization is performed. After yacht power supply stability optimization, the main and auxiliary PLC values ​​are re-acquired. If the coordinated stability deviation value meets the yacht's power supply stability conditions, a power-on operation stability assessment is performed; otherwise, a yacht power supply warning is sent. The power supply stability of the power supply lines between the main PLC and the battery is quantified through the coordinated quantification of the main PLC-power supply stability deviation value and the auxiliary PLC-power supply stability deviation value. The auxiliary PLC power supply line shares the same battery power source as the main PLC power supply line. The stability of the power supply lines between the main PLC and the auxiliary PLC and the battery directly affects the reliability of the entire power supply line. Based on the coordinated quantification results of the stability of the power supply lines between the main PLC and the auxiliary PLC and the battery, it helps to improve the accuracy of yacht power supply resource allocation and management optimization, gradually improve the yacht's power supply adaptability to strong wind interference and load changes, and reduce the frequency of failures.

[0030] It should be explained that the main and auxiliary PLC coordinated stability deviation value is used to measure the power supply stability of the power supply lines between the main and auxiliary PLCs and the storage battery; the yacht power supply stability score includes the main PLC-battery power supply stability value and the auxiliary PLC-battery power supply stability value; the number of interruptions during the main PLC charging process after the storage battery is connected is monitored by a counter, and the sum of this number and the preset main PLC interruption constant is used as the main PLC-battery power supply stability value; the number of interruptions during the auxiliary PLC charging process after the storage battery is connected is monitored by a counter, and the sum of this number and the preset auxiliary PLC interruption constant is used as the auxiliary PLC-battery power supply stability value. The preset values ​​include the preset main PLC interrupt constant and the preset auxiliary PLC interrupt constant, both of which are preset by the user to avoid meaningless deviation values ​​for the coordinated stability of the main and auxiliary PLCs. The preset yacht power supply stability score includes the preset main PLC-battery power supply stability value and the preset auxiliary PLC-battery power supply stability value, and is represented by the average value of the yacht power supply stability score over the corresponding historical time period. The yacht power supply stability condition indicates that the coordinated stability deviation value of the main and auxiliary PLCs is not greater than the preset yacht power supply stability value obtained from the database. The preset yacht power supply stability value is represented by the average value of the coordinated stability deviation values ​​of the main and auxiliary PLCs over the historical time period.

[0031] In this embodiment, after assessing the yacht's operational interference, the decision to optimize the yacht's power supply stability is made based on the yacht's power supply stability assessment results. The yacht operational interference assessment mainly focuses on the interference experienced by the power supply lines in specific environments such as strong wind areas, while the yacht power supply stability assessment focuses on evaluating the stability performance of the power supply itself. The two assessment stages are progressive and interconnected, which helps to avoid blind optimization and can promptly identify problems and potential risks in the yacht's power supply, thereby ensuring the long-term reliable operation of the yacht's power supply system.

[0032] Furthermore, the yacht power supply stability optimization means simultaneously setting the charging time and discharging time; the charging time setting means using a preset charging time adjustment ratio as the adjustment step size for each charging session, progressively increasing the single charging time for the next adjacent specified power supply stability assessment time period; the single charging time does not exceed the preset maximum single charging time, which is pre-set by preset personnel; the preset charging time adjustment ratio is obtained by mapping the yacht power supply stability deviation value and the charging time adjustment mapping set input into the database by the load of the marine charging control box monitored by the electronic load tester; the specified power supply stability assessment time period refers to the preset time period corresponding to the yacht power supply stability assessment; the discharging time setting means using a preset charging time adjustment ratio as the adjustment step size for each charging session, progressively increasing the single charging time for the next adjacent specified power supply stability assessment time period; the specified power supply stability assessment time period refers to the preset time period corresponding to the yacht power supply stability assessment; the discharging time setting means using a preset charging time adjustment ratio as the adjustment step size for each charging session, progressively increasing the single charging time for the next adjacent specified power supply stability assessment time period. The preset discharge duration adjustment ratio serves as the adjustment step size for the single discharge duration, progressively increasing the single discharge duration for the next adjacent specified power supply stability assessment time period. The single discharge duration does not exceed the preset maximum single discharge duration, which is pre-set by preset personnel. The preset discharge duration adjustment ratio is obtained by mapping the yacht's power supply stability deviation value and the load of the marine charging control box into a discharge duration adjustment mapping set in the database. The database contains two mapping sets, one reflecting the mapping relationship between the yacht's power supply stability deviation value and the load of the marine charging control box, and the other reflecting the mapping relationship between the yacht's power supply stability deviation value and the load of the marine charging control box, and the other reflecting the mapping relationship between the yacht's power supply stability deviation value and the load of the marine charging control box, and the preset discharge duration adjustment ratio.

[0033] In this embodiment, by simultaneously setting the charging and discharging durations, the battery charging and discharging process can be balanced, stabilizing voltage and current output. This helps reduce the rate of battery depletion while replenishing power in a timely manner, maintaining stable operation of the power supply line in strong wind areas. By using a preset charging duration adjustment ratio as the step size for adjusting the single charging duration, it helps to accurately adapt to changes in power supply stability. By progressively increasing the single charging duration, sudden changes in charging current and voltage can be avoided, reducing the impact on the battery and charging station, improving charging efficiency, and protecting the battery from damage. Similarly, by using a preset discharging duration adjustment ratio as the step size for adjusting the single discharging duration, it helps to enhance the controllability and safety of the discharging process. By progressively increasing the single discharging duration for the next adjacent specified power supply stability assessment period, dynamic adjustments can be made according to changes in power demand, ensuring stable operation of the yacht as power gradually increases, and guaranteeing the yacht's navigation safety.

[0034] Furthermore, the specific process for evaluating the stability of powered operation is as follows: Powered operation stability indicators are obtained and it is determined whether they meet the stable powered operation conditions. If the powered operation stability indicators meet the stable powered operation conditions, a battery contactor signal qualification assessment is performed; otherwise, powered operation stability optimization is performed. The stable powered operation conditions indicate that the powered operation stability indicators are not greater than the corresponding preset stable powered operation indicators. The preset stable powered operation indicators are represented by the average value of stable powered operation indicators over a historical time period. The stable powered operation indicators are obtained by harmonic averaging the powered operation stability data to be harmonized, and are used to quantify the stability of the powered operation stability data on the main PLC and auxiliary PLC's powered operation. The powered operation stability data to be harmonized represents the result obtained by weighting the powered operation stability data with the corresponding preset powered operation stability value to be harmonized.

[0035] In the embodiments of this application, a set of mapping groups obtained from a database and pre-configured by a preset user is presented, which includes multiple mapping sets. The mapping relationships defined in the mapping group are variable; they can be either a one-to-one correspondence between single parameters or a many-to-one relationship where multiple parameters correspond to one parameter. Specifically, a one-to-one or many-to-one mapping relationship can be established between the power-on stable operation data and the preset power-on stable operation values ​​to be adjusted. By inputting the real-time collected power-on stable operation data into the corresponding mapping group, the corresponding preset power-on stable operation values ​​to be adjusted are output according to the preset mapping relationship. The range of the preset power-on stable operation values ​​to be adjusted is limited to the interval between 0 and 1. The preset power-on stable operation values ​​to be adjusted are determined based on the proportion of the corresponding power-on stable operation data in the overall data, including preset main PLC-power-on stable operation adjustment values, preset auxiliary PLC-power-on stable operation adjustment values, preset qualified main and auxiliary PLC collaborative stability adjustment values, and preset buzzer upper computer display fault count adjustment values, which are used to reflect the degree of influence of the power-on stable operation data on the power-on stable operation indicators.

[0036] The stable power-on operation data includes the main PLC-unstable power-on operation value, the auxiliary PLC-unstable power-on operation value, the qualified main and auxiliary PLC coordinated stability deviation value, and the number of times the buzzer is displayed on the host computer. The stable power-on operation index quantifies the impact of the stable power-on operation data on the stability of the main and auxiliary PLCs during power-on operation. A counter monitors the number of times the buzzer displays a fault after receiving an abnormal prompt within a specified power-on operation period; the sum of this number and a preset fault display constant is used as the number of times the buzzer displays a fault on the host computer. The qualified main and auxiliary PLC coordinated stability deviation value indicates that the main and auxiliary PLCs' power supply stability deviation is not greater than the preset yacht power supply stability value. C. Cooperative stability deviation value; The number of times the main PLC resends real-time communication data within a specified powered-on operation period is monitored by a counter, and the sum of this number and the preset main PLC communication constant is used as the main PLC-powered-on operation instability value; The number of times the auxiliary PLC resends real-time communication data within a specified powered-on operation period is monitored by a counter, and the sum of this number and the preset auxiliary PLC communication constant is used as the auxiliary PLC-powered-on operation instability value; Among them, the preset display fault constant, the preset main PLC communication constant, and the preset auxiliary PLC communication constant are all preset by preset personnel to avoid the numerical values ​​corresponding to the powered-on operation stability indicators being meaningless.

[0037] In this embodiment, by quantitatively analyzing the stable power-on operation data of the PLC to be regulated, the stability of the main PLC and the auxiliary PLC under power-on operation can be specifically measured, thereby obtaining accurate stable power-on operation indicators. Among them, the various indicators in the stable power-on operation data do not exist in isolation, but together reflect the stable power-on operation of the main PLC and the auxiliary PLC through complex interactions and influences. The following describes the interaction and influence mechanisms among various power-on stability data: A higher power-on instability value for the main PLC means more frequent data retransmission by the main PLC, indicating stronger communication link instability. Since the stability of both the main and auxiliary PLCs determines their collaborative operation, the communication stability of the auxiliary PLC may also be affected, leading to a higher power-on instability value for the auxiliary PLC. Higher power-on instability values ​​for both the main and auxiliary PLCs increase the likelihood of communication link anomalies, resulting in more frequent buzzer-related faults displayed on the host computer. A larger deviation in the coordinated stability of the qualified main and auxiliary PLCs indicates less stable power supply between the main and auxiliary PLCs and the battery, potentially leading to asynchronous operation of the main and auxiliary PLCs, increasing the number of anomalies and subsequent buzzer-related faults displayed on the host computer. By deeply analyzing the comprehensive impact of these power-on stability data, a precise assessment of the power-on stability of the main and auxiliary PLCs can be achieved.

[0038] Furthermore, the power-on operation stability optimization means simultaneously setting the charging voltage and charging current. The specific process for setting the charging voltage is as follows: The power-on operation stability index and the number of electromagnetic charge-discharge cycles within a specified power-on operation time period monitored by the counter are input into the charging voltage adjustment mapping set in the database for mapping to obtain a preset charging voltage mapping value. In the next adjacent specified power-on operation time period, the amplitude corresponding to the preset charging voltage mapping value is used as the adjustment step size of the yacht charging voltage, and the yacht charging voltage is gradually increased. This can reduce the battery polarization internal resistance, improve charging efficiency, and thus reduce polarization loss. Moreover, the yacht charging voltage is not greater than the preset maximum charging voltage. The specified power-on operation time period represents the preset time period corresponding to the power-on operation stability assessment. The database contains a set of mapping relationships between the power-on operation stability index and the number of electromagnetic charge-discharge cycles and the corresponding preset charging voltage mapping values.

[0039] The specific process for setting the charging current is as follows: The stable power operation index and the number of electromagnetic charge-discharge cycles are input into the charging current adjustment mapping set in the database for mapping to obtain the preset charging current mapping value; in the next adjacent specified power operation time period, the amplitude corresponding to the preset charging current mapping value is used as the adjustment step size of the yacht charging current, and the yacht charging current is increased step by step. The charging current directly affects the charging speed and battery heating. Gradually increasing the yacht charging current helps to prevent battery separator melting and charging pile overload, avoid overcurrent damage, and the yacht charging current does not exceed the preset maximum charging current. The database contains a set of mapping relationships between the stable power operation index and the number of electromagnetic charge-discharge cycles and the corresponding preset charging current mapping value.

[0040] If the power-on operation stability indicators obtained after optimization meet the power-on operation stability conditions, a battery contactor signal qualification assessment will be performed; otherwise, a power-on operation warning will be sent.

[0041] In this embodiment, by simultaneously setting the charging voltage and charging current, which are core parameters of the battery charging process and jointly determine the charging power and charging efficiency, simultaneous adjustment avoids the local optimum problem caused by optimizing a single parameter. Specifically, the yacht's operating environment is highly variable, and dual-parameter adjustment helps to adapt to areas with strong winds and power supply stability interference, compensate for load consumption, and maintain stable yacht load voltage. The cooperation and correlation between the charging voltage and charging current settings help to balance charging and discharging and reduce the rate of battery capacity degradation.

[0042] Furthermore, the specific process for evaluating the battery contactor signal quality is as follows: Obtain the battery contactor signal transmission qualification value to quantify the qualification level of control signal transmission when the main PLC and auxiliary PLC control the battery contactor; Based on the battery contactor signal transmission qualification value, a judgment is made: if the battery contactor signal transmission qualification value is not greater than the preset signal transmission qualification value obtained from the database, a control interaction delay evaluation is performed; otherwise, battery contactor signal transmission optimization is performed. The preset signal transmission qualification value is represented by the average value of battery contactor signal transmission qualification values ​​over a historical time period; After optimizing the battery contactor signal transmission, if the newly obtained battery contactor signal transmission qualification value is not greater than the preset signal transmission qualification value, a control interaction delay evaluation is performed; otherwise, a control signal transmission warning is sent; The total duration of the battery contactor receiving control commands from the main PLC and auxiliary PLC is monitored using a timer and used as the battery contactor signal transmission qualification value.

[0043] Specifically, optimizing battery contactor signal transmission involves improving the main PLC control response speed by setting the main PLC scan cycle, and improving the secondary PLC control response speed by setting the secondary PLC scan cycle, thereby synergistically reducing the data interaction latency of the main PLC. Simultaneously setting both the main and secondary PLC scan cycles helps achieve synchronous load reduction and coordinated acceleration of the main and secondary PLCs. The main PLC scan cycle setting is as follows: input the battery contactor signal transmission pass value and the number of main PLC scan tasks monitored by the counter into the first scan cycle mapping set in the database, and perform mapping to obtain a preset first scan cycle mapping ratio; in the next adjacent specified transmission time period, use the adjustment range corresponding to the preset scan cycle mapping ratio as the adjustment step size of the main PLC scan cycle, gradually reducing the main PLC scan cycle, ensuring that the main PLC scan cycle is not less than the preset main PLC scan cycle; the specified transmission time period refers to the preset time period corresponding to the battery contactor signal pass evaluation. The secondary PLC scan cycle setting is as follows: input the battery contactor signal transmission pass value and the number of secondary PLC scan tasks into the second scan cycle mapping set in the database, and perform mapping to obtain a preset second scan cycle mapping ratio. For example, in the next adjacent specified transmission time period, the adjustment step size of the secondary PLC scan cycle is used as the adjustment range corresponding to the preset second scan cycle mapping ratio, gradually reducing the secondary PLC scan cycle. The secondary PLC scan cycle is not less than the preset secondary PLC scan cycle. The database contains two mapping sets, reflecting the mapping relationship between the battery contactor signal transmission pass value and the number of main PLC scan tasks, and the corresponding preset first scan cycle mapping ratio; and the mapping relationship between the battery contactor signal transmission pass value and the number of secondary PLC scan tasks, and the corresponding preset second scan cycle mapping ratio. The preset main PLC scan cycle and preset secondary PLC scan cycle are preset by designated personnel. By using the adjustment range corresponding to the preset scan cycle mapping ratio as the adjustment step size of the main PLC scan cycle, gradually reducing the main PLC scan cycle helps prevent bus oscillation and peak load caused by instantaneous high-frequency scanning. By using the adjustment range corresponding to the preset second scan cycle mapping ratio as the adjustment step size of the secondary PLC scan cycle, gradually reducing the secondary PLC scan cycle helps maintain the phase consistency of the main PLC and secondary PLC links, ultimately achieving the optimal balance between communication load and response speed while ensuring signal quality.

[0044] In this embodiment, monitoring the battery contactor signal transmission qualification value to determine whether to optimize the battery contactor signal transmission helps avoid a surge in communication data between the main PLC and the auxiliary PLC due to frequent optimization. While ensuring the quality of the battery contactor signal, it minimizes the load and bus occupancy of the main PLC and the auxiliary PLC. By linking the battery contactor signal qualification assessment and battery contactor signal transmission optimization layer by layer, it helps to resist the problems of ship swaying, power supply fluctuations and signal delays caused by strong winds at sea, thereby reducing signal loss caused by ship swaying.

[0045] Furthermore, the battery contactor signal qualification assessment also includes a control interaction delay assessment. The specific process for the control interaction delay assessment is as follows: A control interaction delay score is obtained to quantify the delay in the real-time information interaction between the yacht's central controller and the marine charging control box; it is determined whether the control interaction delay score meets the control interaction qualification conditions; if the control interaction delay score meets the conditions, a control interaction qualification prompt is sent; otherwise, a yacht electronic control scheduling alarm prompt is sent; the control interaction delay score is obtained by harmonizing and averaging the control interaction delay data to be harmonized; the control interaction delay data to be harmonized is represented by the result of a weighted operation between the control interaction delay data and preset control interaction delay adjustment data.

[0046] In the embodiments of this application, a set of mapping groups retrieved from a database is provided. These mapping groups are pre-configured by designated personnel and contain mapping sets. The mapping relationship is a one-to-one correspondence between single parameters, or a many-to-one relationship where multiple parameters correspond to one parameter. Specifically, a one-to-one or many-to-one mapping association can be established between control interaction delay data and preset control interaction delay adjustment data. By inputting the real-time collected control interaction delay data into the corresponding mapping group, the corresponding preset control interaction delay adjustment data is output according to the pre-set mapping relationship. The preset control interaction delay adjustment data is limited to the range of 0-1. The preset control interaction delay adjustment data is determined based on the proportion of the corresponding control interaction delay data in the overall data, including preset feedback interaction delay adjustment value, power feedback response adjustment value, and battery contactor signal transmission adjustment value, to reflect the impact of control interaction delay data on the control interaction delay score.

[0047] The control interaction delay data includes feedback interaction delay value, power feedback response delay, and battery contactor signal transmission verification value. The feedback interaction delay value is calculated by quantifying the total transmission time from the marine charging control box to the yacht's central controller over a preset time period, using a timer to monitor real-time information. This preset total transmission time is pre-set by a preset team. The power feedback response delay is calculated by comparing the time interval between the charging pile receiving the output power adjustment command and starting power adjustment over a preset time period, using a timer. This preset power adjustment interval is also pre-set by a preset team. The battery contactor signal transmission verification value is represented by a battery contactor signal transmission pass value that is not greater than a preset signal transmission pass value. The control interaction pass condition indicates that the control interaction delay score is not greater than a preset control interaction delay score, which is represented by the average control interaction delay score over a historical time period.

[0048] like Figure 4 The diagram shows the structure of a yacht electronic control intelligent scheduling system based on a multi-sensor linkage feedback mechanism provided in this application embodiment. The system utilizes a yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism, including: a yacht operation interference monitoring module, a yacht power supply stability optimization determination module, a powered operation stability optimization determination module, and a battery contactor signal qualification monitoring module. The yacht operation interference monitoring module performs a yacht operation interference assessment during the multi-sensor linkage feedback process of the marine charging control box to generate a yacht operation interference assessment result, and determines whether to perform a yacht power supply stability assessment based on the yacht operation interference assessment result. The yacht power supply stability optimization determination module sends a yacht electronic control qualification prompt if no yacht power supply stability assessment is performed; otherwise, it determines whether to perform yacht power supply stability optimization based on the yacht power supply stability assessment result. The powered operation stability optimization determination module performs a powered operation stability assessment after the yacht power supply stability assessment is qualified to generate a powered operation stability assessment result, and determines whether to perform powered operation stability optimization based on the powered operation stability assessment result. The battery contactor signal qualification monitoring module performs a battery contactor signal qualification assessment after the powered operation stability assessment is qualified to generate a battery contactor signal qualification assessment result.

[0049] In this embodiment, by comprehensively evaluating the real-time information interaction delay between the yacht's central controller and the marine charging control box using joint control interaction delay data, it helps improve the timeliness of responding to the risk of charging runaway caused by communication delay fluctuations under complex maritime conditions. The control interaction delay data are interconnected and mutually influential. By analyzing their correlation effects, specifically: the larger the feedback interaction delay value, the longer the transmission time of information from the marine charging control box to the yacht's central controller, the lower the timeliness of the control interaction, which in turn leads to a decrease in the response speed of the charging pile receiving the output power adjustment command, resulting in a larger power feedback response delay; the larger the battery contactor signal transmission verification value, the longer the total time for the battery contactor to receive the main PLC transmission control command and the auxiliary PLC transmission control command, which may lead to stronger interference in the information interaction between the marine charging control box and the yacht's central controller, resulting in a larger feedback interaction delay value and a larger power feedback response delay. The control interaction delay data are interconnected and jointly affect the control interaction delay score. Through joint analysis, it helps to maximize the communication bandwidth utilization and energy efficiency balance while ensuring charging safety, ensuring the stability and high efficiency of the entire yacht charging control.

[0050] Depend on Figure 5 The diagram shown is part one of the circuit connection diagrams for the yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism provided in this embodiment of the invention. Figure 6 The diagram shown is part two of the circuit connection diagram for the yacht electronic control intelligent scheduling method based on a multi-sensor linkage feedback mechanism provided in this embodiment of the invention. Figure 5 1-14 in the middle, and Figure 6 The corresponding 1-14 connections; by Figure 5 , 6It can be seen that this circuit uses multiple DC power supplies, where AC represents alternating current and DC represents direct current. R1 and R2 represent resistors. The DC power is centrally distributed via a bus and then converted to AC by inverters (G3 and G6) to supply loads that require AC power (such as three-phase AC motors M~3 and AC loads M1 and M2). The charging interface uses automotive connectors. The battery system (G1 and G2) and the charging interface (round plugs on the left and right sides) are connected in parallel. Their positive terminals are connected to the positive bus (thick red line + blue node, which is the "positive common bus") via contactors (ZKM3, etc.) and DC fuses (such as F1 and F2). The power is then centrally distributed via automotive-grade contactors and DC fuses. Various loads are connected in parallel via DC fuses (F4, F5, F6, F7, etc.) in the branch circuits. Power is drawn from the busbar. The positive output of all power sources and the positive input of all loads are connected through the positive busbar (thick red line + blue node). The negative terminals of the loads are uniformly connected to the "hull frame" to form a common ground loop. The negative terminal of the battery system passes through a shunt, which is connected to the DC energy meter. The hull serves as a common negative circuit, simplifying wiring. The positive terminals of various loads (such as household inverters G4, G5, AC, etc.) are drawn from the busbar, connected to the load through the DC fuses of the branch circuits, and the negative terminals are directly connected to the "hull frame" to form a loop. Automotive-grade contactors (such as ZKM3, K, etc.) control the connection and disconnection of the power supply and the busbar. The DC fuses (F1, F4-F7, etc.) blow when overloaded, cutting off the faulty branch circuit. Insulation detectors (A, B) are connected in parallel between the busbar and the hull frame to monitor the circuit insulation status in real time.

The data and parameter module can be used to implement the functions of data analysis and parameter setting. The user and permission management module can be used to implement the functions of user management and permission setting.

The "Optimization Passed" light is not lit. (Charging Management Interface) Figure 1The interface showcases some of the charging box management equipment, including storage batteries, main PLC, auxiliary PLC, battery fuses, battery contactors, and inverters. Clicking on the circuit structure on this interface will display a detailed circuit connection diagram.

[0053] In summary, the embodiments of this application, by conducting yacht operation interference assessment and determining whether to conduct yacht power supply stability assessment based on the yacht operation interference assessment results, help reduce the occupation of redundant computing resources. If the yacht power supply stability assessment is not conducted, a yacht electronic control qualification prompt is sent; otherwise, the yacht power supply stability optimization is determined based on the yacht power supply stability assessment results. This helps to achieve graded control of power supply stability and reduce the possibility of adjustment lag. After the yacht power supply stability assessment is qualified, a power-on operation stability assessment is conducted and a determination is made whether to conduct power-on operation stability optimization. This helps to achieve coordinated control and avoid overcharging or undercharging caused by single-parameter adjustment, thereby helping to improve the degree of optimization qualification and achieve precise control of energy conversion. After the power-on operation stability assessment is qualified, a battery contactor signal qualification assessment is conducted and a determination is made whether to conduct control interaction delay assessment. This helps to enhance the PLC's anti-interference capability and avoid insufficient anti-interference capability due to signal loss. This improves the timeliness of intelligent scheduling of yacht electronic control and solves the problem of low timeliness of intelligent scheduling of yacht electronic control caused by PLC power-on operation stability interference in the prior art.
