Description

Technical Field

[0001] The present invention relates to the technical field of information data, and more specifically, to a network data information security protection system. Background Art

[0002] The thermal control system ensures that the electronic and sensing components of the radar operate at an appropriate temperature, reducing the degradation of component performance and error accumulation caused by overheating. If the thermal control system fails, the radar may experience data transmission errors or signal instability, resulting in inaccurate distance detection data, and even affecting the real-time and accuracy of network data. Moreover, the failure of the thermal control system may trigger the automatic protection mechanism of the radar equipment (such as frequency reduction, suspension or shutdown), causing the radar to stop working temporarily, resulting in a monitoring blind area, and further affecting the data flow and monitoring range of the entire radar network, thus affecting the coverage and integrity of the network information system. In the existing published literature, in the literature (Chen Kui. Design of Radar Chassis Thermal Control System [D]. Southeast University, 2016), taking the radar chassis as the research object, an optimized thermal design method and temperature real-time control system are proposed, but no emergency treatment plan for the failure of the thermal control system is mentioned. Once the radar thermal control system fails, it may cause the equipment to shut down at high temperature or the performance to decline, affecting the stability of data transmission, resulting in data loss. Therefore, it is necessary to add redundant design and multi-level protection mechanisms in the thermal control system design to cope with sudden heat dissipation failures. To solve the above problems, a technical solution is provided herein. Summary of the Invention

The construction steps of the dual - linkage emergency protection model are as follows:

[0025] When the temperature change value of the temperature monitoring unit is greater than or equal to the preset temperature change threshold, a fault warning is triggered at this time, and a primary response is triggered. At this time, the fan inside the radar chassis will be automatically activated for heat dissipation;

[0026] If within the preset heat dissipation duration, the temperature change value of the temperature monitoring unit is still greater than or equal to the preset temperature change threshold, a secondary response is triggered at this time, and the working power of the radar chassis is reduced to reduce the heat generation.

[0034] The multi-level protection linkage subsystem is used to perform hierarchical response through a dual linkage emergency protection model after detecting a fault warning signal to reduce the temperature of the radar chassis.

[0035] Through the dual-temperature monitoring and hierarchical protection response mechanism, the temperature of the radar chassis is monitored in real time, and active heat dissipation and power reduction protection are carried out in case of abnormalities, effectively preventing problems such as high-temperature shutdown and performance degradation; the data information security diagnosis subsystem monitors the health status of the data stream in real time, discovers and processes potential faults in signal transmission in a timely manner, ensures the stability of data transmission and reduces the risk of data loss; the intelligent redundant switching and load distribution subsystem quickly switches to the redundant chassis and redistributes the load when the main chassis fails or the temperature is abnormal, ensuring that data transmission is not interrupted, thereby improving the system stability and anti-interference ability; through the fast response mechanism to temperature changes and load distribution management, the multi-level protection linkage subsystem can reduce the overheating loss of equipment and extend the service life of radar equipment; the combination of temperature monitoring and early warning and multi-level protection linkage realizes the dual guarantee of the radar chassis and data transmission, improving the system's automatic protection ability and emergency response efficiency.

[0036] The chassis temperature monitoring and early warning subsystem includes a temperature monitoring module, a central data monitoring module, a fault early warning response module, and a multi-level power reduction protection module; the temperature monitoring module is connected to the central data monitoring module, the central data monitoring module is connected to the fault early warning response module, and the fault early warning response module is connected to the multi-level power reduction protection module;

[0037] The temperature monitoring module is used to monitor and analyze the temperature inside the radar chassis: the radar chassis is divided into several temperature monitoring units according to the bottom, several monitoring points are set in each temperature monitoring unit, and temperature sensors are set at each monitoring point to respectively obtain the first temperature value of all monitoring points before the radar chassis runs and the second temperature value of all monitoring points after running;

[0038] The central data monitoring module is used to obtain the first temperature value and the second temperature value, calculate the first temperature average value according to the first temperature value, calculate the second temperature average value according to the second temperature value, and construct a temperature change value monitoring model based on the first temperature value and the second temperature value. The formula of the temperature change value monitoring model is:

[0039] ;

[0040] In the formula: is the temperature change value, is the second temperature value of the i-th monitoring point, is the second temperature average value, is the first temperature value of the i-th monitoring point, is the first temperature average value, is the number of monitoring points;

[0041] The fault warning response module is used to extract the temperature change value, compare the temperature change value with a preset temperature change threshold. If the temperature change value is greater than or equal to the preset temperature change threshold, a fault warning will be triggered; if the temperature change value is less than the preset temperature change threshold, no fault warning will be triggered;

[0042] The multi-level power reduction protection module is used to obtain the temperature change values of each temperature monitoring unit, construct a discriminant model for the emergency shutdown of the chassis based on the temperature change values, and determine whether the radar chassis needs to be shut down urgently. The formula for the discriminant model for the emergency shutdown of the chassis is:

[0045] By dividing the bottom of the chassis into multiple temperature monitoring units and arranging temperature sensors at each monitoring point, the comprehensive monitoring of the temperature inside the chassis is realized, which helps to identify temperature anomalies in specific areas and effectively prevent local overheating; through the collaborative work of the central data monitoring module and the fault warning response module, when the temperature change exceeds the threshold, the warning can be automatically triggered, timely prompting potential overheating risks, facilitating the rapid adoption of measures to ensure the safe operation of the system; the multi-level power reduction protection module can reduce the power in stages when the temperature is abnormal, ensuring that the equipment will not be completely shut down under high temperature conditions, delaying the temperature rise through power reduction protection, and effectively guaranteeing the system stability; the discriminant model for emergency shutdown comprehensively evaluates according to the temperature change conditions of each temperature monitoring unit, and only triggers shutdown when the temperature change value exceeds the emergency alarm threshold, avoiding unnecessary shutdowns and effectively preventing equipment damage due to high temperature; using the temperature change value monitoring model and the discriminant model for emergency shutdown, the system can comprehensively analyze the temperature fluctuation situation, not only judge the current temperature level, but also evaluate the temperature change trend, further improving the recognition accuracy of temperature anomalies.

[0046] The intelligent redundant switching and load distribution subsystem includes a redundant chassis automatic switching module and a task load distribution and scheduling module; the redundant chassis automatic switching module is connected to the task load distribution and scheduling module;

[0047] The redundant chassis automatic switching module is used to automatically activate a preset redundant radar chassis when any one of a fault warning or an emergency alarm is detected. For the activated redundant radar chassis, the chassis temperature monitoring and warning subsystem is used to perform double temperature monitoring and warning on the redundant radar chassis again. The specific steps for performing double temperature monitoring and warning on the redundant radar chassis are as follows:

[0048] Monitor and analyze the temperature inside the redundant radar chassis: Divide the redundant radar chassis into several temperature monitoring units according to the bottom, set several monitoring points in each temperature monitoring unit, set temperature sensors at each monitoring point, and respectively obtain the first temperature values of all monitoring points before the redundant radar chassis operates and the second temperature values of all monitoring points after it operates;

[0049] Obtain the first temperature values and the second temperature values of all monitoring points before the redundant radar chassis operates, calculate the first temperature average value according to the first temperature values, calculate the second temperature average value according to the second temperature values, and construct a temperature change value monitoring model based on the first temperature values and the second temperature values. The formula of the temperature change value monitoring model is:

[0050] ;

[0051] In the formula: is the temperature change value of the temperature monitoring unit inside the redundant radar chassis, is the second temperature value of the i-th monitoring point inside the redundant radar chassis, is the second temperature average value inside the redundant radar chassis, is the first temperature value of the i-th monitoring point inside the redundant radar chassis, is the first temperature average value inside the redundant radar chassis, is the number of monitoring points;

[0052] Extract the temperature change value of the temperature monitoring unit inside the redundant radar chassis, compare the temperature change value of the temperature monitoring unit inside the redundant radar chassis with a preset temperature change threshold. If the temperature change value is greater than or equal to the preset temperature change threshold, a fault warning will be triggered; if the temperature change value is less than the preset temperature change threshold, no fault warning will be triggered;

[0053] Then obtain the temperature change values of each temperature monitoring unit inside the redundant radar chassis, construct a redundant radar chassis emergency shutdown discrimination model based on the temperature change values, and perform discrimination on whether the redundant radar chassis needs to be shut down emergently. The formula of the redundant radar chassis emergency shutdown discrimination model is:

[0054] ;

[0055] In the formula: is the redundant radar chassis emergency shutdown discrimination value, is the number of temperature monitoring units, is the temperature change value of the j-th temperature monitoring unit in the redundant radar chassis, is the average value of the temperature change values of each temperature monitoring unit in the redundant radar chassis; compare the emergency shutdown discrimination value of the redundant radar chassis with the preset emergency alarm threshold. If the emergency shutdown discrimination value of the redundant radar chassis is greater than or equal to the preset emergency alarm threshold, an emergency alarm will be triggered and a shutdown notice will be issued; if the emergency shutdown discrimination value of the redundant radar chassis is less than the preset emergency alarm threshold, no emergency alarm will be triggered.

[0056] When a failure or temperature control problem occurs in the main chassis, the redundant chassis automatic switching module can immediately activate the standby chassis to ensure the normal operation of the equipment and avoid data interruption. Through automatic switching, the manual intervention time is reduced and the fault response efficiency is improved; after the redundant chassis is started, through the temperature monitoring and early warning system for dual temperature control analysis, the temperature change trend of the standby chassis can be continuously tracked to ensure that the redundant system operates within a safe temperature range and effectively prevent the occurrence of secondary faults; the temperature change value monitoring model can accurately calculate the temperature changes at each monitoring point of the redundant chassis, provide real-time temperature data, and quickly identify temperature anomalies through preset thresholds to further ensure the reliability of the redundant system; the emergency shutdown discrimination model of the redundant chassis will dynamically judge whether to shut down according to the fluctuations of the temperature change value monitoring unit, avoid damage to the equipment caused by continuous temperature rise, help extend the service life of the equipment and reduce the maintenance cost; the task load distribution and scheduling module can intelligently allocate load requirements and optimize the operating state of the standby chassis, thereby reducing the temperature control pressure on the main chassis. Through reasonable load distribution, the redundant system can reduce the risk of single chassis overload and ensure the stability and reliability of the overall system; the multi-level protection process from redundant switching to temperature monitoring to emergency shutdown can provide hierarchical protection when equipment anomalies occur, and avoid affecting the continuity of data transmission and task execution due to equipment shutdown under high temperature or load pressure.

[0057] The task load distribution and scheduling module is used to reallocate tasks through the chassis task load distribution model and evaluate the new load volume after the load transfer of the faulty chassis. The specific construction of the chassis task load distribution model is as follows: The radar chassis includes , where is the first radar chassis, is the second radar chassis, is the N-th radar chassis, and the current task load is , then the total load volume at this time is . When the f-th radar chassis has a failure, it is necessary to allocate the task load volume of the radar chassis according to the chassis task load distribution formula:

[0058] ;

[0059] Wherein: is the task load of the a-th radar chassis after reallocation, is the task load of the a-th radar chassis before reallocation, is the total number of radar chassis, is the radar chassis task load, is the a-th radar chassis, is the f-th radar chassis.

[0060] When a certain radar chassis fails, its task load will be evenly distributed to other normally operating chassis, so that when other chassis bear the additional load, the increment of the load is relatively balanced, avoiding the situation of overloading a single chassis and improving the stability of the system; through the automatic adjustment of the load distribution model, the tasks of the faulty chassis can be quickly transferred to other chassis, avoiding the interruption of tasks due to a single failure, thus ensuring the continuity of the radar system tasks; when a failure occurs, the redistribution of the task load enables all chassis resources to be effectively utilized, thereby improving the resource utilization efficiency of the system, avoiding the waste of idle resources, and further optimizing the overall performance of the system; through the load distribution of the model, the system has strong fault tolerance and redundancy capabilities in the face of chassis failures, can automatically adjust and distribute the load, and ensure that the system can still operate smoothly without adding hardware, enhancing the stability of the system; during the load redistribution process, the load distribution of each radar chassis tends to be balanced, so that the computing and data transmission efficiency of each radar chassis remains at a relatively high level, reducing the problems of task delay and decline in execution efficiency.

[0061] The data information security diagnosis subsystem includes a signal data acquisition module and a data stream health diagnosis module;

[0062] The signal data acquisition module is used to obtain the first working parameters when the radar performs signal transmission; the first working parameters include signal data intensity, signal data fluctuation frequency, and signal data extension duration;

[0063] The data stream health diagnosis module is used to establish a data stream health monitoring model to judge whether there is a fault in data transmission. The formula of the data stream health monitoring model is:

[0064] ;

[0065] ;

[0066] ;

[0067] Wherein: is the signal data strength at time e, is the signal data strength at time e - 1, is the preset signal data strength threshold, is the signal data fluctuation frequency at time e, is the signal data fluctuation frequency at time e - 1, is the preset signal data fluctuation frequency threshold.

[0068] By obtaining the first working parameters such as signal data strength, fluctuation frequency, and extension duration, the data information security diagnosis subsystem can monitor the key indicators in data transmission in real time, quickly identify abnormal situations, and help detect and locate problems as early as possible; by monitoring the abnormal fluctuations of signal data through the data stream health monitoring model, it can timely identify potential security risks in signal transmission, ensure the security of the data transmission process, and prevent information leakage or damage caused by transmission errors; when the signal strength or frequency fluctuation exceeds the preset threshold, a fault warning can be triggered, enabling maintenance personnel to take measures in a timely manner, reducing the impact of unstable factors on the system data transmission, and improving the overall data transmission stability of the system; the data stream health diagnosis module can identify potential transmission delay problems through the detection of the extension duration, give an early warning of possible transmission interruptions, ensure the smooth completion of tasks, and reduce the efficiency loss caused by delays or interruptions; the set health monitoring model effectively isolates abnormal transmission data through threshold judgment, thereby ensuring the accuracy of the data, preventing incorrect data from entering the system or interfering with radar tasks. When abnormal signal data transmission occurs, it quickly locates the abnormal working parameters and triggers the corresponding fault information, helping technicians determine the root cause of the fault faster and shortening the fault troubleshooting and repair time.

[0069] The multi-level protection linkage subsystem is used to establish a dual-linkage emergency protection model to take measures when the fault warning response module triggers a fault warning. The construction steps of the dual-linkage emergency protection model are as follows:

[0070] When the temperature change value of the temperature monitoring unit is greater than or equal to the preset temperature change threshold, a fault warning is triggered at this time, and a primary response is triggered. At this time, the fan inside the radar chassis will be automatically activated for heat dissipation. At this time, the cooling power is:

[0071] ;

[0072] In the formula: is the cooling power, is the specific heat capacity of air, is the air supply volume of the fan, is the temperature change amount after the primary response;

[0073] If within the preset heat dissipation duration, the temperature change value of the temperature monitoring unit is still greater than or equal to the preset temperature change threshold, a secondary response is triggered at this time. By reducing the operating power of the radar chassis to reduce the heat generation, the power reduction calculation formula is:

[0074] ;

[0075] In the formula: is the power reduction of the radar chassis, is the normal power of the radar chassis, is the power reduction ratio of the radar chassis.

[0076] The primary response immediately activates the fan for heat dissipation when the temperature exceeds the threshold, providing immediate cooling, which helps to quickly control the temperature within a reasonable range and avoid further failures caused by excessive temperature. When the primary response fails to achieve the ideal heat dissipation effect, the secondary response will automatically reduce the operating power of the chassis to further control the temperature by reducing the heat generation. The dual response mechanism increases the system's tolerance to high-temperature failures and reduces the likelihood of system failures due to the failure of a single cooling measure. When the temperature cannot be controlled within the safe range by fan cooling, the secondary response reduces the heat generation by reducing the chassis power to ensure that the system does not continue to operate under high-temperature conditions, thereby extending the service life of the equipment and improving the system stability. After triggering the secondary response for power reduction, the heat generation inside the chassis decreases, which helps to protect the internal sensitive electronic components and avoid damage or performance degradation caused by local overheating. The fan cooling and power reduction operations are dynamically adjusted to effectively manage the system energy consumption and avoid unnecessary power consumption, especially when the temperature is already close to the safe level, which can reduce the additional cooling cost and improve the system energy efficiency. The multi-level protection linkage mechanism reduces the frequency of failures and the system maintenance requirements, enabling the equipment to remain stable in high-temperature environments and other conditions, reducing the frequency of manual maintenance, and lowering the equipment operation and maintenance costs. Through the preset temperature monitoring and dual emergency response mechanism, temperature anomalies can be identified and responded to in the early stage, reducing the risk of system damage, and at the same time providing data support for fault analysis, facilitating maintenance personnel to quickly judge and take appropriate measures.

[0077] In the embodiments of the present invention, through a dual temperature monitoring and hierarchical protection response mechanism, the temperature of the radar chassis is monitored in real time, and active heat dissipation and power reduction protection are carried out in case of abnormalities, effectively preventing problems such as high-temperature shutdown and performance degradation; the data information security diagnosis subsystem monitors the health status of the data stream in real time, discovers and processes potential faults in signal transmission in a timely manner, ensures the stability of data transmission and reduces the risk of data loss; the intelligent redundant switching and load distribution subsystem quickly switches to the redundant chassis and redistributes the load when the main chassis fails or the temperature is abnormal, ensuring that data transmission is not interrupted, thereby improving the system stability and anti-interference ability; through the rapid response mechanism to temperature changes and load distribution management, the multi-level protection linkage subsystem can reduce the overheating loss of the equipment and extend the service life of the radar equipment; the combination of temperature monitoring and early warning and multi-level protection linkage realizes double protection of the radar chassis and data transmission, improving the automatic protection ability and emergency response efficiency of the system.

[0078] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all of them should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.

The construction steps of the double linkage emergency protection model are as follows: When the temperature change value of the temperature monitoring unit is greater than or equal to the preset temperature change threshold, a fault warning is triggered and a primary response is triggered. At this time, the fan in the radar chassis will be automatically activated for heat dissipation; If the temperature change value of the temperature monitoring unit is still greater than or equal to the preset temperature change threshold within the preset heat dissipation time, a secondary response is triggered to reduce the heat generation by reducing the operating power of the radar chassis.
