110. in response to a component failure, operational parameters and failure indication information associated with the component are obtained.
The operation parameter is a parameter associated with the component when the component operates in the equipment, for example, a parameter in the equipment which is affected when the component fails.
For example, when the device is a phase modulator and the component is a rotor, the operating parameters associated with the component may be an absolute value of a relative deviation of the excitation current, a maximum value of a turning gear end shaft vibration pass frequency change rate, a maximum value of a field cover vibration pass frequency change rate, a percentage δ maximum value of a magnetic flux difference, a maximum value of a turning gear end bearing bush temperature, a maximum value of a field end bearing bush temperature, a peak-to-peak value of a shaft voltage, and the like.

And the membership degree represents the degree of the operation parameter belonging to the fault grade, and is calculated through the current degradation degree. For example, if the fault level includes a normal level, a minor fault level, a major fault level, and an emergency fault level, the membership level of the operation parameter belonging to the normal level, the membership level belonging to the minor fault level, the membership level belonging to the major fault level, the membership level belonging to the emergency fault level, and the like are obtained according to the current degradation level corresponding to the operation parameter.

From table 1, it can be seen that the values of a and b may be:
TABLE 1
For example, if the operation parameter is the absolute value of the relative deviation of the excitation current and is equal to x1, the degradation degree function associated with the absolute value of the relative deviation of the excitation current is I (x 1), and the current degradation degree corresponding to x1 is I1.
The operation parameter is the maximum value of the turning end shaft vibration pass frequency and is equal to x2, the degradation degree function related to the maximum value of the turning end shaft vibration pass frequency is I (x 2), and then the current degradation degree corresponding to x2 is I2.
The operation parameter is the maximum value of the vibration pass frequency change rate of the turning gear end shaft and is equal to x3, the degradation degree function related to the maximum value of the vibration pass frequency change rate of the turning gear end shaft is I (x 3), and then the current degradation degree corresponding to x3 is I3.

The operation parameter is the maximum value of the temperature of the bearing at the turning gear end and is equal to x7, the degradation function associated with the maximum value of the temperature of the bearing at the turning gear end is I (x 7), and then the current degradation corresponding to x7 is I7.

The operation parameter is the shaft voltage peak-to-peak value and is equal to x9, the degradation degree function associated with the shaft voltage peak-to-peak value is I (x 9), and the current degradation degree corresponding to x9 is I9.
In some embodiments, in order to allow for the possibility of associating a degree of degradation to which an operating parameter corresponds with a fault level of a component, determining a degree of membership to each fault level of the operating parameter based on a current degree of degradation comprises:
acquiring membership functions corresponding to all fault levels;
and determining the membership degree of the operation parameter belonging to each fault grade according to the current degradation degree and all membership degree functions.
Wherein a membership function is used to relate the operating parameter to the fault level by the degree of degradation.
The failure levels include a normal level, a slight failure level, a serious failure level, and an urgent failure level, and are membership functions corresponding to the failure levels, for example, referring to fig. 1 d.
The membership function corresponding to the normal rank is r1:
r1＝{0.5-0.5*sin[π(I-0.15)/0.3]，1∈[0,0.3]；0，I∈(0.3，1]}。
the membership function corresponding to the level of a minor fault is r2:
the membership function corresponding to the level of catastrophic failure is r3:
the membership function corresponding to the level of catastrophic failure is r4:
r4＝{0，I∈[0,0.7]，0.5+0.5*sin[π(I-0.85)/0.3]，I∈(0.7，1]}。
substituting the current deterioration degree I1 into r1 to obtain w11; substituting the current degradation degree I1 into r2 to obtain w12; substituting the current deterioration degree I1 into r3 to obtain w13; the current degradation degree I1 is substituted into r4 to obtain w14. The membership degree vectors W1 (W11, W12, W13, W14) of x1 are formed by the W11, W12, W13 and W14, the remaining current degradation degrees I2 to I9 are calculated by the calculation method to obtain the membership degree vectors W3 and W4 of the membership degree vectors W2 and x3 and W5 and W6 of the membership degree vectors W6 and X6 and W7 of the membership degree vectors W7 and W8 and W9 of the membership degree vectors W8 and X9 of the membership degree vectors W2 and x3 and x5 of x2, so that membership degree matrixes W (W1, W2, W3, W4, W5, W6, W7, W8 and W9) corresponding to all the operation parameters are formed, and the membership degree matrixes are 9 rows and 4 columns.
In some embodiments, considering more than one operating parameter associated with a component, in evaluating a fault of the component, in order to fuse the degrees of membership corresponding to all operating parameters to generate a parameter convenient for evaluating the fault of the component, determining a first deduction value according to all degrees of membership corresponding to each operating parameter includes:
acquiring a first weight corresponding to the operation parameter and a second weight corresponding to each fault level;
multiplying and summing the first weight, all the second weights and the membership degrees corresponding to the operation parameters to obtain target values corresponding to the operation parameters;
and determining a first deduction value according to the target values corresponding to all the operating parameters.
Wherein the first weight is a specific gravity occupied by the preset operation parameter in component fault evaluation.
The method for acquiring the first weight corresponding to the operation parameter comprises the following steps:
TABLE 2
For example, as can be seen from table 2, the absolute value of the relative deviation of the excitation current, the maximum value of the shaft vibration pass frequency at the turning gear end, the maximum value of the vibration pass frequency at the excitation end cover, the maximum value of the magnetic flux difference percentage δ, the maximum value of the temperature of the shaft bushing at the turning gear end and the maximum value of the temperature of the shaft bushing at the excitation end all have a weight coefficient of 1, and the weight coefficient of 0.4 corresponding to the peak-to-peak value of the shaft voltage, wherein the sum of the weight coefficients corresponding to all the operation parameters is 8.4, and the weight coefficient corresponding to each operation parameter is divided by the sum of the weight coefficients to obtain the first weight corresponding to each operation parameter. The first weights corresponding to all the operation parameters may specifically be: <xnotran> M (1,1,1,1,1,1,1,1,0.4)/8.4, , (1,1,1,1,1,1,1,1,0.4) 8.4 , M (5,5,5,5,5,5,5,5,2)/42. </xnotran>
Wherein the second weight is a weight associated with the failure level.
For example, if the weight corresponding to the level with a normal failure level is 100, the weight corresponding to the level with a slight failure level is 70, the weight corresponding to the level with a serious failure level is 30, and the weight corresponding to the level with an urgent failure level is 0, a second weight vector corresponding to all failure levels is formed: y (100, 70, 30, 0).
Multiplying and summing the first weight, all the second weights and the membership degrees corresponding to the operation parameters to obtain target values corresponding to the operation parameters; and according to the target values corresponding to all the operating parameters, the calculation method for determining the first deduction value comprises the following steps: first withhold value S 0 ＝100-sum[(M*W)*Y]。
In some embodiments, to give a weight to the failure level, the weight corresponding to the failure level may be determined by a membership function corresponding to the failure level, and before the second weight corresponding to each failure level, the method further includes:
determining a target degradation degree according to a membership function corresponding to the fault grade and a membership degree equal to 1;
and determining a second weight corresponding to the fault grade according to the target degradation degree corresponding to the membership function.
Wherein the target degradation degree is a degradation degree corresponding to a membership degree equal to 1 in the membership degree function.
For example, a degree of membership equal to 1 may correspond to a target degree of degradation of 0 in the degree of membership function r1, a degree of membership equal to 1 may correspond to a target degree of degradation of 0.3 in the degree of membership function r2, a degree of membership equal to 1 may correspond to a target degree of degradation of 0.7 in the degree of membership function r3, and a degree of membership equal to 1 may correspond to a target degree of degradation of 1 in the degree of membership function r 4.
That is, the target degradation degree belonging to the level in which the failure level is normal is 0, the target degradation degree belonging to the level in which the failure level is minor failure is 0.3, the target degradation degree belonging to the level in which the failure level is major failure is 0.7, and the target degradation degree belonging to the level in which the failure level is major failure is 1, so that in order to give a weight to the failure level, the percentages of 0, 0.3, 0.7, and 1 in all the target degradation degrees may be calculated, respectively, to obtain the percentage of 0 when the target degradation degree is 0, the percentage of 30 when the target degradation degree is 0.3, the percentage of 70 when the target degradation degree is 0.7, and the percentage of 100 when the target degradation degree is 1.
Considering that the fault levels are given weight, a small fault level is given to a large value according to the severity of the fault level, a serious fault level is given to a large value, namely, the fault level corresponding to a percentage of 100 is a normal level, the fault level corresponding to a percentage of 70 is a slight fault level, the fault level corresponding to a percentage of 30 is a serious fault level, and the fault level corresponding to a percentage of 0 is an emergency fault level, so that a second weight vector corresponding to all the fault levels is formed: y (100, 70, 30, 0).
130. And calculating a second deduction value by adopting the fault prompt information, wherein the second deduction value represents the fault degree of the component.
And the second deduction value is a deduction value obtained through fault prompt information when the component is evaluated to be in fault, and the deduction value represents the fault degree of the component.
In some embodiments, when evaluating the failure level of a component, in order to take into account factors influencing the failure evaluation of the component, the failure prompt message sent by the device to the component when the component fails is taken into account in the failure evaluation, where the failure prompt message includes a plurality of failure levels and the number of failures corresponding to the failure levels, the plurality of failure levels includes a first level and a second level, and the second level is lower than the first level, and the calculating, using the failure prompt message, a second deduction value includes:
determining a middle value corresponding to the first grade according to the number of the faults corresponding to the first grade and the number of the faults corresponding to the second grade;
if the intermediate value corresponding to the highest fault level meets the preset condition, based on the intermediate values corresponding to all fault levels, the determination method for determining the second deduction value comprises the following steps:
if the intermediate value corresponding to the highest fault level meets the preset condition, acquiring a mapping relation between the preset intermediate value and a preset deduction function;
determining a target deduction function according to a mapping relation between a preset intermediate value and a preset deduction function and the intermediate value corresponding to the highest fault level;
determining a second deduction value according to the target deduction function and a middle value corresponding to the fault grade except the highest fault grade;
and if the intermediate value corresponding to the fault grade of the highest level does not meet the preset condition, taking the preset deduction value as a second deduction value.
The number of the faults is the number corresponding to the same fault of the component.
For example, when a component has a fault, the device sends out a slight fault prompt, and the device counts the slight fault prompts, so that the number of the slight faults of the component can be obtained.
Wherein the first level is higher than the second level. For example, the first level may be a normal level, a light failure level, a severe failure level, or an emergency failure level.
For example, when the first rank is a slight fault rank, and the second rank is a normal rank, the normally corresponding rank has no corresponding fault number, and at this time, the calculation formula of the intermediate value corresponding to the slight fault rank is a '= mod (a, 5), where a' is the intermediate value corresponding to the slight fault rank, and a is the fault number corresponding to the slight fault rank.
For example, when the first level is a level of a serious fault, the second level is a normal level and a level of a slight fault, where the normal level has no corresponding fault number, and the fault number corresponding to the slight fault is a, at this time, a calculation formula of an intermediate value corresponding to the serious fault is b '= mod (b + int (a/5), 3), where b' is an intermediate value corresponding to the level of the slight fault, and b is a fault number corresponding to the level of the serious fault.
For example, when the first level is an emergency fault level, the second level is a normal level, a slight fault level and a serious fault level, where the normal level has no corresponding fault number, the slight fault number is a, and the slight fault number is b, and at this time, the calculation formula of the intermediate value corresponding to the emergency fault level is c '= c + int (b + int (a/5))/3, where c' is the intermediate value corresponding to the emergency fault level, and c is the fault number corresponding to the emergency fault level.
The intermediate value corresponding to the highest fault level can be calculated by c' = c + int (b + int (a/5))/3.
The preset deduction function is used for calculating the deduction value obtained by sending the component fault information through the intermediate value calculation equipment.
The preset intermediate value is a preset intermediate value associated with the preset deduction function.
And the mapping relation between the preset intermediate value and the preset deduction function is used for associating the preset intermediate value with the preset deduction function.
And the target deduction function is a preset deduction function mapped by the middle value corresponding to the highest fault level.
The method for determining the second deduction value according to the target deduction function and the intermediate value corresponding to the fault grade except the fault grade of the highest grade comprises the following steps:
if c ' =1, the corresponding target deduction function is F =85+2b ' + a ', wherein a slight fault deducts 1 point and a serious obstacle deducts 2 points in the target deduction function.
If c '=0 and b' ≠ 0, the corresponding target deduction function is F =50+4b '+2a', wherein one slight fault in the target deduction function deducts 2 points, and one serious fault in the target deduction function deducts 4 points.
If c '=0, b' =0 and a '≠ 0, the corresponding target deduction function is F =15+4a', wherein a slight fault in the target deduction function deducts 4 points.
The deduction corresponding to the component fault in the target deduction function can be determined according to actual conditions.
If the intermediate value corresponding to the highest fault level does not satisfy the preset condition, the method of using the preset deduction value as the second deduction value may be: when c' is more than or equal to 2, the second deduction value F is equal to a preset deduction value, the preset deduction value can be 100, and the second deduction value can be set according to actual conditions.
140. And according to the first deduction value and the second deduction value, fault evaluation is carried out on the component to obtain an evaluation result.
And the evaluation result is the corresponding fault grade of the component after fault evaluation. For example, the evaluation result may be normal, slight fault, serious fault, urgent fault, and the like.
According to the first deduction value and the second deduction value, the method for fault assessment of the component comprises the following steps:
the score interval corresponding to the fault grade of the component is as follows:
component Normal rating [85, 100], component light failure rating [50, 85), component heavy failure rating [15, 50), component Emergency failure rating [0, 15).
Fault evaluation formula of component S =100-S 0 -F, wherein S 0 Is the first withholding value, and F is the second withholding value.
For example: according to the score S obtained by subtracting the first deduction value and the second deduction value from the full score of 100, comparing the interval where the S is located, and when the S is in the interval of [85, 100], the component is in a normal grade; when S is in the interval of [50, 85), the component is at a level of slight failure; when S is in the interval of [15, 50), the component is at a severe fault level; when S is in the interval of [0, 15), the component is at a level of catastrophic failure.
In some embodiments, the above evaluation method may be loaded on a computer controlling the apparatus, on a separate device which may evaluate the apparatus, and so on.
As can be seen from the above, the embodiment of the present application may acquire the operation parameters and the fault prompt information associated with the component in response to the component fault; calculating a first deduction value by adopting the operation parameters, wherein the first deduction value represents the fault degree of the component; calculating a second deduction value by adopting the fault prompt information, wherein the second deduction value represents the fault degree of the component; and according to the first deduction value and the second deduction value, fault evaluation is carried out on the component to obtain an evaluation result.
According to the scheme, the operation parameters and the fault reminding information can map the fault degree of the component, the fault reminding information can be the reminding information of slight faults, serious faults, emergent faults and the like generated when the component works in equipment, so that the operation parameters and the fault reminding information related to the component can be considered simultaneously when the component is subjected to fault evaluation, the fault degree of the component is comprehensively evaluated, a user can replace the component in the equipment in time according to the evaluation result of the component, and the influence of component damage on the normal operation of the equipment is reduced.
