[0026] Embodiment 1: As Figure 1 shown, this embodiment provides an operation and maintenance strategy generation method based on operation evaluation and device status evaluation, including the following steps: Construct an operation evaluation model for operation and maintenance personnel based on operation and maintenance personnel operation data and an operation evaluation formula; Specifically, obtain operation behavior data and operation compliance data of operation and maintenance personnel, and establish a safe operation baseline for operation and maintenance personnel based on the operation behavior data and operation compliance data; Construct an operation evaluation model for operation and maintenance personnel based on the safe operation baseline of operation and maintenance personnel and the operation evaluation formula; The specific operation evaluation formula is: In the formula, R i is the evaluation score of the i-th baseline item, S im is the score of the m-th baseline index corresponding to the i-th baseline item, W im is the weight coefficient of the m-th baseline index corresponding to the i-th baseline item, j is the number of baseline indexes corresponding to the i-th baseline item, R is the total sum of the evaluation scores of the baseline items, and n is the number of baseline items; The safe operation baseline of the operation and maintenance personnel includes baseline items, baseline indexes, and inspection rules and evaluation suggestion attribute information corresponding to the baseline indexes; The operation and maintenance personnel operation data includes at least operation behavior data and operation compliance data.

[0027] In this embodiment, according to the operation and maintenance process of the power monitoring system, user roles are at least divided into operation and maintenance administrators, operation and maintenance auditors, and operation and maintenance personnel. By monitoring the operation behaviors of operation and maintenance personnel, such as operation paths and operation instructions, operation behavior data and operation compliance data of operation and maintenance personnel can be collected. Through feature analysis of the operation behavior data and operation compliance data, the operation baseline items of operation and maintenance personnel and the baseline indicators corresponding to the baseline items can be determined. Thus, an operation and maintenance personnel safety operation baseline is established by combining the inspection rules and evaluation recommendation attribute information of the baseline item indicators. The operation and maintenance personnel safety operation baseline at least includes the planned completion rate, operation password secrecy level, access link compliance, and operation instruction compliance. Moreover, through the operation and maintenance personnel safety operation baseline, suspicious behaviors of operation and maintenance personnel can be captured, and the professional capabilities of various role personnel can also be evaluated. Then, an operation and maintenance personnel operation evaluation model is constructed based on the operation and maintenance personnel safety operation baseline and the operation evaluation formula. The operation and maintenance personnel operation evaluation model can comprehensively evaluate the operations of operation and maintenance personnel based on the operation and maintenance personnel safety operation baseline, determine the weight coefficients and index scores of the baseline indicators based on the importance of each baseline indicator in the established operation and maintenance personnel safety operation baseline. If B represents the baseline item, and there are n baseline items in the operation and maintenance personnel safety operation baseline, then the set of baseline items can be expressed as B = {B 1 ,B 2 ,B 3 ,...,B n}, and the baseline item set needs to satisfy If B i = {B i1 ,B i2 ,...,B ij}, j is the number of baseline indicators of the baseline item B i , and the baseline indicator scores corresponding to the baseline item indicators can be expressed as S i = {S i1 ,S i2 ,...,S ij}, correspondingly, the weight coefficients corresponding to the baseline item indicators can be expressed as W i = {W i1 ,W i2 ,...,W ij}.

[0028] Construct an equipment status evaluation model based on equipment performance parameters and equipment status evaluation criteria; Specifically, obtain equipment performance parameters, and delimit the equipment status deterioration level, status quantity, and score based on the equipment performance parameters; Construct a calculation formula for the deduction score of the status quantity based on the equipment status deterioration level, status quantity, status quantity weight, and basic deduction score; determine the equipment status level based on the rules and criteria of the power monitoring system, and construct an equipment status evaluation criterion according to the equipment status level and score. Construct an equipment status evaluation model based on the calculation formula for the deduction score of the status quantity and the equipment status evaluation criterion.

[0029] In this embodiment, the equipment involved is the same as the equipment involved in the safe operation and maintenance process of the power monitoring system, and is divided into operation and maintenance terminals and operation and maintenance objects. The operation and maintenance terminals at least include workstations and bastion hosts, and the operation and maintenance objects at least include host devices, network devices, general security devices, and special security devices. According to the rules and criteria of the power monitoring system, the equipment status can be divided into normal status, attention status, abnormal status, and alarm status; the normal status means that all status quantities of the equipment are within a stable and good range, and the equipment can operate normally; the attention status means that the change trend of each status quantity of the equipment is close to the standard limit value and has a tendency to continue to develop, but it has not exceeded the standard limit value at present, and it can continue to operate, but this equipment needs to be paid more attention to; the abnormal status means that one or more status quantities of the equipment have changed greatly and have approached or slightly exceeded the standard limit value, and the equipment should be monitored and potential risks should be processed in a timely manner; the severe status means that one or more status quantities of the equipment seriously exceed the standard limit value, and it is necessary to quickly conduct problem investigation and execute risk disposal; and, according to the degree of influence of the status quantity on the safe operation of the equipment, different status quantities are divided into 4 levels from light to heavy, and the weight coefficients of the 4 levels of the status quantity are 1, 2, 3, and 4 from light to heavy respectively. Secondly, in order to evaluate the equipment status, the equipment status evaluation model determines the deduction score after the equipment status deterioration based on the equipment status deterioration degree and status quantity weight, and realizes the quantification of the equipment status; the equipment status deterioration degree is divided into 4 levels from light to heavy, namely Safety Level I, Safety Level II, Safety Level III, and Safety Level IV. The deduction score after the equipment status deterioration, that is, the status quantity deduction score, is equal to the basic deduction score of the status quantity multiplied by the weight coefficient. And the equipment status evaluation model takes the equipment status deterioration degree as the trigger condition. Taking the host device and the isolation device as examples, the deduction rules for the equipment status quantity are shown in Table 1: Table 1. Deduction Rules for Equipment Status Quantity Secondly, after the equipment status is quantified, it is also necessary to use the equipment status evaluation criterion to judge the equipment status. The equipment status evaluation criterion is shown in Table 2: Table 2. Equipment Status Evaluation Criterion The deduction score corresponding to the single item is calculated from the single item status quantity, and the total deduction score corresponds to the deduction score calculated from multiple status quantities. When judging the equipment status, the highest status corresponding to the single item deduction and the total deduction of the equipment is taken as the judgment status of the equipment, that is, the larger value of the single item deduction and the total deduction is taken as the deduction score used for equipment judgment.
