Description

Technical Field

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

[0002] The thermal control system ensures that the radar's electronic and sensor components work at an appropriate temperature, reducing component performance degradation and error accumulation caused by overheating. If the thermal control system fails, the radar may experience data transmission errors or unstable signals, resulting in inaccurate distance detection data, and even affecting the real-time and accuracy of network data. In addition, the failure of the thermal control system may trigger the automatic protection mechanism of the radar equipment (such as frequency reduction, pause or shutdown), causing the radar to temporarily stop working, resulting in a monitoring blind area, which in turn affects the data flow and monitoring range of the entire radar network, and affects the coverage and integrity of the network information system. In the existing public literature, the document (Chen Kui. Design of Thermal Control System of Radar Chassis [D]. Southeast University, 2016) takes the radar chassis as the research object and proposes an optimized thermal design method and temperature real-time control system, but does not mention the emergency treatment plan when the thermal control system fails. Once the radar thermal control system fails, it may cause the equipment to shut down at high temperature or performance degradation, affecting the stability of data transmission, thereby causing data loss. Therefore, it is necessary to add redundant design and multi-level protection mechanism in the thermal control system design to deal with sudden heat dissipation failures. In order to solve the above problems, a technical solution is now provided. Summary of the invention

[0013] Through dual temperature monitoring and hierarchical protection response mechanisms, the radar chassis temperature is monitored in real time, and active heat dissipation and power reduction protection are performed under abnormal conditions, effectively preventing high-temperature shutdown and performance degradation problems; the data information security diagnosis subsystem monitors the health of the data flow in real time, promptly discovers and handles potential faults in signal transmission, 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 uninterrupted data transmission, thereby improving system stability and anti-interference capabilities; through the rapid response mechanism to temperature changes and load distribution management, the multi-level protection linkage subsystem can reduce equipment overheating losses and extend the service life of radar equipment; the combination of temperature monitoring and early warning and multi-level protection linkage realizes dual protection of radar chassis and data transmission, and improves the system's automated protection capabilities and emergency response efficiency.

[0014] 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; 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 a temperature sensor is set at each monitoring point to obtain the first temperature value of all monitoring points before the radar chassis is operated and the second temperature value of all monitoring points after the operation; The central data monitoring module is used to obtain the first temperature value and the second temperature value, calculate the first temperature mean according to the first temperature value, calculate the second temperature mean according to the second temperature value, and build a temperature change value monitoring model based on the first temperature value and the second temperature value.

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. The multi-level power reduction protection module is used to obtain the temperature change value of each temperature monitoring unit, and build a chassis emergency shutdown judgment model based on the temperature change value to judge whether the radar chassis needs emergency shutdown. The formula of the chassis emergency shutdown judgment model is: ; Where: is the chassis emergency shutdown judgment value, is the number of temperature monitoring units, is the temperature change value of the jth temperature monitoring unit, is the average of the temperature change values ​​of each temperature monitoring unit; the chassis emergency shutdown judgment value is compared with the preset emergency alarm threshold. If the chassis emergency shutdown judgment value is greater than or equal to the preset emergency alarm threshold, an emergency alarm will be triggered and a shutdown notification will be issued; if the chassis emergency shutdown judgment value is less than the preset emergency alarm threshold, the emergency alarm will not be triggered.

[0015] By dividing the bottom of the chassis into multiple temperature monitoring units and arranging temperature sensors at each monitoring point, comprehensive monitoring of the internal temperature of the chassis can be achieved, which helps to identify temperature anomalies in specific areas and effectively prevent local overheating; through the coordinated work of the central data monitoring module and the fault warning response module, when the temperature change exceeds the threshold, an early warning can be automatically triggered, and potential overheating risks can be promptly prompted, so as to facilitate rapid measures to ensure the safe operation of the system; the multi-level power reduction protection module can reduce power in stages when the temperature is abnormal, ensuring that the equipment will not be completely shut down under high temperature conditions, and delaying the temperature rise through power reduction protection, effectively ensuring the stability of the system; the emergency shutdown discrimination model conducts a comprehensive evaluation based on the temperature changes of each temperature monitoring unit, and only triggers a shutdown when the temperature change value exceeds the emergency alarm threshold, avoiding unnecessary shutdowns and effectively preventing damage to equipment due to high temperature; using the temperature change value monitoring model and the emergency shutdown discrimination model, the system can comprehensively analyze the temperature fluctuation, not only to determine the current temperature level, but also to evaluate the temperature change trend, further improving the accuracy of identifying temperature anomalies.

[0016] The intelligent redundant switching and load distribution subsystem includes a redundant chassis automatic switching module and a task load distribution scheduling module; the redundant chassis automatic switching module is connected to the task load distribution scheduling module; The redundant chassis automatic switching module is used to automatically activate the preset redundant radar chassis when any of the fault warning or emergency alarm is detected. For the activated redundant radar chassis, the chassis temperature monitoring and early warning subsystem performs dual temperature monitoring and early warning on the redundant radar chassis again. The specific steps for performing dual temperature monitoring and early warning on the redundant radar chassis are as follows: Monitor and analyze the temperature in 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 a temperature sensor at each monitoring point, and obtain the first temperature value of all monitoring points before the redundant radar chassis is operated and the second temperature value of all monitoring points after the operation; Obtain the first temperature value and the second temperature value of all monitoring points before the redundant radar chassis is operated, calculate the first temperature mean according to the first temperature value, calculate the second temperature mean according to the second temperature value, and build 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: ; Where: is the temperature change value of the temperature monitoring unit in the redundant radar chassis, is the second temperature value of the i-th monitoring point in the redundant radar chassis, is the second temperature mean in the redundant radar chassis, is the first temperature value of the i-th monitoring point in the redundant radar chassis, is the first temperature average value in the redundant radar chassis, is the number of monitoring points; Extract the temperature change value of the temperature monitoring unit in the redundant radar chassis, compare the temperature change value of the temperature monitoring unit in the redundant radar chassis with a preset temperature change threshold, and 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; Then, the temperature change values ​​of each temperature monitoring unit in the redundant radar chassis are obtained, and a redundant radar chassis emergency shutdown discrimination model is constructed based on the temperature change values ​​to determine whether the redundant radar chassis needs emergency shutdown. The formula of the redundant radar chassis emergency shutdown discrimination model is: ; Where: It is the emergency shutdown judgment value of the redundant radar chassis. is the number of temperature monitoring units, is the temperature change value of the jth temperature monitoring unit in the redundant radar chassis, is the average of the temperature change values ​​of each temperature monitoring unit in the redundant radar chassis; the emergency shutdown judgment value of the redundant radar chassis is compared with the preset emergency alarm threshold. If the emergency shutdown judgment 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 notification will be issued; if the emergency shutdown judgment value of the redundant radar chassis is less than the preset emergency alarm threshold, the emergency alarm will not be triggered.

[0017] When the main chassis fails or has temperature control problems, the redundant chassis automatic switching module can instantly activate the standby chassis to ensure normal operation of the equipment and avoid data interruption. Through automatic switching, the manual intervention time is reduced and the efficiency of fault response is improved. After the redundant chassis is started, the temperature monitoring and early warning system is used to perform dual temperature control analysis, which can continuously track the temperature change trend of the standby chassis, 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 of 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 redundant chassis emergency shutdown discrimination model will dynamically determine whether it is necessary to shut down according to the fluctuation of the temperature change value monitoring unit to avoid damage to the equipment caused by continuous temperature increase, which helps to extend the service life of the equipment and reduce maintenance costs. The task load distribution scheduling module can intelligently distribute load requirements and optimize the operating status of the standby chassis, thereby reducing the temperature control pressure of the main chassis. Through reasonable load distribution, the redundant system can reduce the risk of overloading a single chassis and ensure the stability and reliability of the overall system. The multi-level protection process from redundant switching to temperature monitoring and then to emergency shutdown can provide hierarchical protection when abnormal conditions occur in the equipment to avoid affecting the continuity of data transmission and task execution due to equipment shutdown under high temperature or load pressure.

[0018] The task load distribution scheduling module is used to redistribute tasks through the chassis task load distribution model and evaluate the new load after the load of the failed chassis is transferred. The chassis task load distribution model is constructed as follows: The radar chassis includes ,in, For the first radar chassis, For the second radar chassis, For the Nth radar chassis, the current task load is , then the total load is , when the fth radar chassis When a fault occurs, the radar chassis needs to be The task load The distribution is based on the chassis task load distribution formula: ; Where: is the task load of the ath radar chassis after redistribution, is the task load of the ath radar chassis before redistribution, is the total number of radar chassis, For radar chassis The task load, is the ath radar chassis, is the f-th radar chassis.

[0019] When a radar chassis fails, its task load will be evenly distributed to other normally operating chassis, so that when other chassis bear additional loads, the load increment is relatively balanced, avoiding the situation where a single chassis is overloaded, thereby improving the stability of the system; through the automatic adjustment of the load distribution model, the task of the faulty chassis can be quickly transferred to other chassis to avoid task interruption due to a single failure, thereby ensuring the continuity of the radar system task; when a failure occurs, the redistribution of task loads makes all chassis resources 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 in the face of chassis failures, and can automatically adjust and distribute the load to ensure that the system can still run smoothly without adding hardware, thereby enhancing the stability of the system; in the process of load redistribution, the load distribution of each radar chassis tends to be balanced, so that the calculation and data transmission efficiency of each radar chassis is maintained at a high level, reducing the problems of task delays and reduced execution efficiency.

[0020] The data information security diagnosis subsystem includes a signal data acquisition module and a data flow health diagnosis module; The signal data acquisition module is used to obtain the first working parameters of the radar when transmitting signals; the first working parameters include signal data strength, signal data fluctuation frequency, and signal data extension time; The data stream health diagnosis module is used to establish a data stream health monitoring model to determine whether there is a fault in data transmission. The formula of the data stream health monitoring model is: ; ; ; Where: 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, It is the preset signal data fluctuation frequency threshold.

[0021] By acquiring the first working parameters such as signal data strength, fluctuation frequency and extension time, the data information security diagnosis subsystem can monitor the key indicators in data transmission in real time, quickly identify abnormal situations, and help to find and locate problems as early as possible; by monitoring the abnormal fluctuation of signal data through the data flow 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 is detected to exceed the preset threshold, a fault warning can be triggered, so that maintenance personnel can take timely measures to reduce the impact of unstable factors on system data transmission and improve the overall data transmission stability of the system; the data flow health diagnosis module can identify potential transmission delay problems through the detection of extension time, warn of possible transmission interruptions in advance, ensure the smooth completion of tasks, and reduce efficiency losses caused by delays or interruptions; the set health monitoring model effectively isolates abnormal transmission data through threshold judgment, thereby ensuring the accuracy of data, preventing erroneous data from entering the system or interfering with radar tasks, and when signal data transmission is abnormal, the abnormal working parameters are quickly located and the corresponding fault information is triggered, helping technicians to determine the root cause of the fault more quickly and shorten troubleshooting and maintenance time.

[0022] The multi-level protection linkage subsystem is used to establish a double linkage emergency protection model to take measures when the fault warning response module triggers a fault warning. 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. At this time, the cooling power is: ; Where: is the cooling power, is the specific heat capacity of air, The air volume supplied by the fan, is the temperature change after the primary response; 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, the secondary response is triggered at this time, and the working power of the radar chassis is reduced to reduce the heat. The power reduction calculation formula is: ; Where: 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.

[0023] The primary response immediately activates fan cooling when the temperature exceeds the threshold, providing instant cooling, helping 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 cooling effect, the secondary response will automatically reduce the operating power of the chassis, further controlling the temperature by reducing heat generation. The dual response mechanism increases the system's tolerance for high-temperature failures and reduces the possibility of system failure due to failure of a single cooling measure; when the temperature cannot be controlled within a safe range through fan cooling, the secondary response reduces heat generation by reducing chassis power to ensure that the system does not continue to run under high temperature conditions, thereby extending the service life of the equipment and improving system stability; after the secondary response is triggered to reduce power, the heat generation in the chassis Reduction helps protect sensitive internal electronic components and avoid damage or performance degradation caused by local overheating; fan cooling and power reduction operations can be dynamically adjusted to effectively manage system energy consumption and avoid unnecessary power consumption, especially when the temperature is close to a safe level, which can reduce additional cooling costs and improve system energy efficiency; the multi-level protection linkage mechanism reduces the frequency of faults and system maintenance requirements, allowing the equipment to remain stable in high temperature environments, reducing the frequency of manual maintenance and reducing equipment operation and maintenance costs; through preset temperature monitoring and dual emergency response mechanisms, temperature anomalies can be identified and responded to at an early stage, reducing the risk of system damage, while providing data support for fault analysis, allowing maintenance personnel to quickly judge and take appropriate measures.

[0024] The embodiment of the present invention monitors the temperature of the radar chassis in real time through dual temperature monitoring and hierarchical protection response mechanism, and performs active heat dissipation and power reduction protection under abnormal conditions, effectively preventing high-temperature shutdown and performance degradation problems; the data information security diagnosis subsystem monitors the health status of the data flow in real time, promptly discovers and handles potential faults in signal transmission, 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 uninterrupted data transmission, thereby improving the stability and anti-interference ability of the system; through the rapid response mechanism to temperature changes and load distribution management, the multi-level protection linkage subsystem can reduce equipment overheating losses and extend the service life of radar equipment; the combination of temperature monitoring and early warning and multi-level protection linkage realizes dual protection of radar chassis and data transmission, and improves the system's automated protection capability and emergency response efficiency.
