[0037] Figure 2 This is a system block diagram of Embodiment 2 of the present invention. DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1: Figure 1 As shown, the operation monitoring and maintenance system applied to the power grid information terminal proposed by the present invention includes a terminal hardware risk analysis module, a terminal software operation monitoring module, a terminal communication transmission evaluation module, a terminal network security anomaly decision module and a maintenance early warning terminal;

[0040] The terminal hardware risk analysis module conducts a comprehensive analysis on the hardware equipment risk of the power grid information terminal, receives the corresponding terminal hardware judgment symbol and terminal environment judgment symbol of the power grid information terminal, and generates a low-risk signal for the terminal hardware if LP-2∩XP-2 is received. In other cases, a high-risk signal for the terminal hardware is generated, and the high-risk signal for the terminal hardware is sent to the maintenance warning terminal, which can reasonably evaluate the hardware risk of the power grid information terminal and provide timely feedback.

[0041] The terminal hardware risk analysis module sends the terminal hardware low-risk signal to the terminal software operation monitoring module. When the terminal software operation monitoring module receives the terminal hardware low-risk signal, it monitors and analyzes the software program operation status of the power grid information terminal to accurately feedback the software program operation performance of the power grid information terminal, and generates a terminal software operation alarm signal or a terminal software normal operation signal based on this, and sends the terminal software operation alarm signal to the maintenance warning terminal; the specific analysis process of the terminal software operation monitoring module is as follows:

[0042] The number of times the software program in the power grid information terminal crashes within a unit time is obtained and marked as a software program crash detection value, and the timing starts when the program crashes until the program is restored to obtain a crash recovery time value, and all crash recovery time values ​​within a unit time are summed up to obtain a software program crash time value;

[0043] The software program collapse detection value and the software program collapse time value are numerically compared with the preset software program collapse detection threshold and the preset software program collapse time threshold respectively. If the software program collapse detection value or the software program collapse time value exceeds the corresponding preset threshold, indicating that the operation of the power grid information terminal is not smooth within a unit time, a terminal software operation alarm signal is generated.

[0044] If the software program crash detection value and the software program crash time value do not exceed the corresponding preset thresholds, the average speed of the software program in the power grid information terminal for power grid data processing per unit time is collected and marked as the software running speed measurement value;

[0045] By formula The software program crash detection value RM, the software program crash time value RW and the software operation speed measurement value RY are numerically calculated to obtain the terminal software operation evaluation value RL; wherein wq1, wq2 and wq3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the terminal software operation evaluation value RL is, the worse the software program operation performance of the power grid information terminal is in general;

[0046] The terminal software operation evaluation value RL is numerically compared with the preset terminal software operation evaluation threshold. If the terminal software operation evaluation value RL exceeds the preset terminal software operation evaluation threshold, it indicates that the software program operation performance of the power grid information terminal is generally poor, and a terminal software operation alarm signal is generated; if the terminal software operation evaluation value RL does not exceed the preset terminal software operation evaluation threshold, it indicates that the software program operation performance of the power grid information terminal is generally good, and a terminal software operation normal signal is generated.

[0047] The terminal software operation monitoring module sends the normal operation signal of the terminal software to the terminal communication transmission evaluation module. When receiving the normal operation signal of the terminal software, the terminal communication transmission evaluation module analyzes the communication transmission performance of the power grid information terminal to accurately evaluate the communication status of the power grid information terminal, and generates a terminal communication qualified signal or a terminal communication abnormal signal based on this, and sends the terminal communication abnormal signal to the maintenance warning terminal; the specific analysis process of the terminal communication transmission evaluation module is as follows:

[0048] The communication signal strength data, communication signal delay data and communication packet loss rate data collected from the power grid information terminal are The communication signal strength data MY, the communication signal delay data NS and the communication packet loss rate data NF are numerically calculated to obtain a communication transmission detection value LP; wherein sy1, sy2 and sy3 are preset proportional coefficients whose values ​​are greater than zero, and the larger the value of the communication transmission detection value LP is, the worse the real-time communication status of the power grid information terminal is;

[0049] The communication transmission analysis value is obtained by calculating the average of all communication transmission detection values ​​LP within a unit time, and the communication transmission detection value LP is numerically compared with a preset communication transmission detection threshold, and the number of communication transmission values ​​exceeding the preset communication transmission detection threshold within a unit time is marked as a communication transmission anomaly analysis value;

[0050] The communication transmission analysis value and the communication transmission anomaly value are numerically compared with the preset communication transmission analysis threshold and the preset communication transmission anomaly threshold respectively. If the communication transmission analysis value or the communication transmission anomaly value exceeds the corresponding preset threshold, it indicates that the communication transmission performance of the power grid information terminal in unit time is generally poor, and a terminal communication abnormality signal is generated; if both the communication transmission analysis value and the communication transmission anomaly value do not exceed the corresponding preset threshold, it indicates that the communication transmission performance of the power grid information terminal in unit time is generally good, and a terminal communication qualified signal is generated.

[0051] The terminal communication transmission evaluation module sends the terminal communication qualified signal to the terminal network security abnormality decision module. When the terminal network security abnormality decision module receives the terminal communication qualified signal, it makes a decision analysis on the network security abnormality of the power grid information terminal to accurately judge the degree of network threat to the power grid information terminal, and generates a terminal network security alarm signal or a terminal network security normal signal accordingly, and sends the terminal network security alarm signal to the maintenance warning terminal; the specific analysis process of the terminal network security abnormality decision module is as follows:

[0052] The total number of network attacks on power grid information terminals per unit time is collected and marked as the terminal network attack frequency value, and the number of network attacks that have not been successfully intercepted per unit time is calculated by ratio with the terminal network attack frequency value to obtain the terminal interception abnormality value;

[0053] The terminal network decision value TL is obtained by numerically calculating the terminal network strike frequency value QP and the terminal interception abnormal value NS through the formula TL=ny1×QP / (ny2+3.628)+ny2×NS; wherein ny1 and ny2 are preset proportional coefficients, ny2>ny1>0.362; and the larger the value of the terminal network decision value TL is, the more serious the network threat status of the power grid information terminal is within a unit time;

[0054] The terminal network decision value TL is numerically compared with the preset terminal network decision threshold. If the terminal network decision value TL exceeds the preset terminal network decision threshold, it indicates that the network threat situation of the power grid information terminal in unit time is more serious, and a terminal network security alarm signal is generated; if the terminal network decision value TL does not exceed the preset terminal network decision threshold, it indicates that the network risk of the power grid information terminal in unit time is relatively small, and a terminal network security normal signal is generated.

[0055] Furthermore, when the maintenance warning terminal receives a high-risk signal of terminal hardware, a terminal software operation alarm signal, a terminal communication abnormality signal or a terminal network security alarm signal, it will issue a corresponding warning. It can comprehensively monitor the power grid information terminal and gradually and accurately determine its abnormal performance, and promptly remind management personnel to perform maintenance on the power grid information terminal, thereby ensuring the operational safety and stability of the power grid information terminal, significantly reducing the management difficulty of management personnel, and having a high level of intelligence.

[0056] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the terminal hardware risk analysis module is communicatively connected to the terminal hardware monitoring module, and the terminal hardware monitoring module monitors the hardware equipment of the power grid information terminal and assigns the terminal hardware judgment symbol LP-1 or LP-2 through analysis;

[0057] The terminal hardware judgment symbol LP-1 or LP-2 is sent to the terminal hardware risk analysis module, which can not only accurately feedback the hardware status of the power grid information terminal, but also provide information support for the analysis process of the terminal hardware risk analysis module to ensure the accuracy of its analysis results; the specific analysis process of the terminal hardware monitoring module is as follows:

[0058] The average temperature of the corresponding monitoring point on the power grid information terminal within a unit time and the total time duration that the temperature exceeds the corresponding preset temperature threshold are collected and marked as the terminal point temperature performance value and the terminal point temperature danger time value, and the terminal point temperature performance value and the terminal point temperature danger time value are numerically compared with the corresponding preset terminal point temperature performance threshold and the preset terminal point temperature danger time threshold, respectively. If the terminal point temperature performance value or the terminal point temperature danger time value exceeds the corresponding preset threshold, the corresponding monitoring point is marked as a terminal alarm point;

[0059] If there is a terminal alarm point on the power grid information terminal within a unit time, indicating that the terminal equipment condition of the power grid information terminal is poor, the terminal hardware judgment symbol LP-1 is assigned;

[0060] If there is no terminal alarm point on the power grid information terminal within a unit time, the average vibration amplitude of the power grid information terminal within a unit time and the total duration of the vibration amplitude exceeding the preset vibration amplitude threshold are marked as the terminal vibration performance value and the terminal vibration risk value, respectively, and the terminal vibration performance value and the terminal vibration risk value are numerically compared with the preset terminal vibration performance threshold and the preset terminal vibration risk threshold, respectively;

[0061] If the terminal vibration performance value or the terminal vibration risk value exceeds the corresponding preset threshold, indicating that the terminal equipment of the power grid information terminal is in poor condition, the terminal hardware judgment symbol LP-1 is assigned; if neither the terminal vibration performance value nor the terminal vibration risk value exceeds the corresponding preset threshold, indicating that the terminal equipment of the power grid information terminal is in good condition, the terminal hardware judgment symbol LP-2 is assigned.

[0063] The terminal environment judgment symbol XP-1 or XP-2 is sent to the terminal hardware risk analysis module, which can not only accurately feedback the degree of adverse impact of the environment in which the power grid information terminal is located, but also provide information support for the analysis process of the terminal hardware risk analysis module, further ensuring the accuracy of its analysis results; the specific analysis process of the terminal environment monitoring module is as follows:

[0064] The environment in which the power grid information terminal is located is obtained and marked as the target environment, and the parameters to be monitored in the target environment (including ambient temperature, ambient humidity, dust concentration and other parameters) are marked as control parameters; the real-time data of the corresponding control parameters are collected, and the real-time data is compared with the corresponding preset data requirements. If the real-time data does not meet the corresponding preset data requirements, it indicates that the real-time risk brought by the corresponding control parameters to the power grid information terminal is relatively large, and the corresponding control parameters are judged to be in a reference table risk state;

[0065] The total time length of time that the corresponding control parameter is in the reference table risk state within a unit time is collected and marked as the total risk time value, and when it is judged that the corresponding control parameter is in the reference table risk state, the deviation value of the real-time data compared with the corresponding preset data is marked as the reference deviation amplitude value, and all the reference deviation amplitude values ​​of the corresponding control parameter within a unit time are averaged to obtain the reference deviation table inspection value, and the reference deviation amplitude value with the largest value corresponding to the corresponding control parameter within a unit time is marked as the reference deviation hidden danger value;

[0066] By formula The total risk time value GY, the deviation table inspection value FK and the deviation hidden danger value XW of the corresponding control parameter are numerically calculated to obtain the parameter pipe condition value GX; wherein eu1, eu2 and eu3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the parameter pipe condition value GX, the greater the potential damage caused by the performance of the corresponding control parameter per unit time to the power grid information terminal;

[0067] The parameter control condition value GX is numerically compared with the corresponding preset parameter control condition threshold. If the parameter control condition value GX exceeds the corresponding preset parameter control condition threshold, it indicates that the performance of the corresponding control parameter in a unit time has caused great potential damage to the power grid information terminal, and the corresponding control parameter is marked as a hidden danger parameter; if there is a hidden danger parameter in the environment where the power grid information terminal is located in a unit time, it indicates that the environment where the power grid information terminal is located is initially poor and is likely to cause damage to the power grid information terminal, and the terminal environment judgment symbol XP-1 is assigned;

[0068] If there are no hidden danger parameters in the environment where the power grid information terminal is located within a unit time, a set of preset risk weight values ​​are respectively assigned to each control parameter in advance, wherein the values ​​of the preset risk weight values ​​are all positive numbers; and the greater the adverse impact of the abnormality of the corresponding control parameter on the power grid information terminal, the greater the value of the preset risk weight value matching it;

[0069] The product of the parameter management condition value of the corresponding control parameter and the corresponding preset risk weight value is marked as the parameter management evaluation value, and the parameter management evaluation values ​​of all control parameters are summed up to obtain the parameter comprehensive evaluation value; it should be noted that the larger the value of the parameter comprehensive evaluation value, the worse the environmental performance of the environment in which the power grid information terminal is located, and the greater the safety hazard to the power grid information terminal;

[0070] The parameter comprehensive evaluation value is numerically compared with the preset parameter comprehensive evaluation threshold. If the parameter comprehensive evaluation value exceeds the preset parameter comprehensive evaluation threshold, it indicates that the environment in which the power grid information terminal is located is generally poor, which is not conducive to the safe and stable operation of the power grid information terminal and is likely to cause damage to the power grid information terminal.
