Fig. 2 is to protect target control in a kind of state monitoring method step S30 of DC control and protection system shown in FIG. 1
Shield signal is input in monitoring formula, calculates the flow chart of monitoring threshold.On the basis of the above embodiments, the present embodiment pair
Technical solution has done further instruction and optimization, specifically, as shown in Fig. 2, S30: target control protection signal is input to
It monitors in formula, calculates specifically including for monitoring threshold:
S31: function name, signal name and the operator title in monitoring formula are parsed using Formula Solution parser.
Specifically, by pre-establishing function name set, signal name set and operator name set, also, will
Function name in function name set, the signal name in signal name set and the operator in operator name set
Title compares the ASCII character of title according to arranging from long to short if Name Length is identical, according to the ASCII character of title from small
It is arranged to big sequence.Then, function name set, signal name set and the fortune pre-established is combined using Formula Solution parser
Operator name set parses function name, signal name and operator title in monitoring formula.
S32: traversal monitoring formula is successively replaced using target control protection signal replacement signal name, using function object
It changes function name, accord with title using operation object replacement operation, obtain monitoring model.
Specifically, traversal monitoring formula, replaces signal name first with target control protection signal, then utilizes function
Object replacement function title recycles operation object replacement operation to accord with title, obtains and protects signal, function comprising target control
The monitoring model of object and operation object.
S33: pre-processing monitoring model, obtains regularization monitoring model.
As preferred embodiment, monitoring model is pre-processed, show that regularization monitoring model specifically includes:
The parameter of each function object in monitoring model is split using bracket, and the left side that and function object is adjacent
Bracket is deleted；
Negative calculate is taken to be converted to computer identifiable subtraction the monocular in monitoring model.
Specifically, determining each function object in monitoring model first, then determine that and function object is adjacent
Left bracket and with the symmetrical right parenthesis of the left bracket.The determining process with the symmetrical right parenthesis of left bracket includes: to work as to detect
When the adjacent left bracket of function object, 0 is set by counter, then successively traverses each formula element in function model, when
When formula element is left bracket, counter is subtracted 1, when the value of counter when formula element is right parenthesis by counter plus 1
When being 0, then the right parenthesis is the adjacent symmetrical right parenthesis of left bracket of and function object.Specifically, utilizing two left brackets
In left bracket " (", using two right parenthesis ")) " replacement monitoring model in " ((" replacement monitoring model right parenthesis ") ", benefit
With right parenthesis and left bracket ") (comma in " replacement monitoring model, ", so that realizing will be each in monitoring model using bracket
The purpose that the parameter of function object is split.For example, carrying out function object to monitoring model " F (1+G (2,3), H (4)) "
Non-parametric segmentation after, the regularization monitoring model that obtains is " F ((1+G ((2) (3))) (H ((4)))) ".
A kind of preferably realize is present embodiments provided to divide the parameter of each function object in monitoring model using bracket
The method cut also can use other modes in others are implemented and realize, the present embodiment is limited not as specific.
It should be noted that being needed after being split the parameter of each function object in monitoring model using bracket
The adjacent left bracket of and function object is deleted.During converting regularization monitoring model to center linear table, it is
After guarantee has finally traversed regularization monitoring model, it can will convert the left bracket in stack and all delete, it is therefore desirable to keep rule
The sum for then changing the left bracket and function object in monitoring model is consistent with the sum of right parenthesis, therefore to delete and function object
The adjacent left bracket in right side includes to avoid leaving in conversion stack with the consistent left side of function object quantity in regularization monitoring model
Number, cause subsequent calculating mistake.
Specifically, in view of computer cannot identify the problem of taking negative operation, this reality during executing calculation procedure
Example is applied by judging that monitoring model takes negative calculating with the presence or absence of monocular, specifically including the first character judged in monitoring model is
No is negative sign "-", or judge to whether there is character " (- " in monitoring model.If it is determined that in monitoring model there are monocular take it is negative
It calculates, then needs to take the monocular in monitoring model negative calculate to be converted to the identifiable subtraction of computer.It specifically includes: if
First character in monitoring model is negative sign "-", then adds Plus "0" before monitoring model；By the character " (- " in monitoring model
Replace with character " (0- ".For example, monitoring model " -10+5*F (- 1*2+3) " is converted to the identifiable subtraction of computer
Afterwards, the regularization monitoring model obtained is " 0-10+5*F (0-1*2+3) ".
S34: constant, target control protection signal, function object and the operation object in regularization monitoring model are pressed
It is arranged according to computer execution sequence, obtains center linear table；
S35: the linear table element in intermediate linear list is calculated according to execution sequence using stack is calculated, obtains monitoring
Threshold value.
It is understood that since computer can not directly hold regularization monitoring model according to the sequence for calculating priority
Row calculating operation, therefore the present embodiment is by protecting signal, function object for the constant in regularization monitoring model, target control
It is arranged with operation object according to computer execution sequence, and according to putting in order to obtain center linear table.Then, pass through calculating
Stack calculates the linear table element in intermediate linear list according to execution sequence, obtains monitoring threshold.In it is understood that
Between linear table element in linear list namely execute tactic constant according to computer, signal, function are protected in target control
Object and operation object.
As it can be seen that the state monitoring method of DC control and protection system provided in this embodiment, can efficiently and accurately calculate
Detection threshold value out.
Fig. 3 is to monitor regularization in a kind of state monitoring method step S34 of DC control and protection system shown in Fig. 2
Constant, target control protection signal, function object and operation object in model are arranged according to computer execution sequence, are obtained
The process schematic of center linear table.On the basis of the above embodiments, the present embodiment has done further technical solution
Bright and optimization, referring to FIG. 3, S34: by constant, target control protection signal, function object and the fortune in regularization monitoring model
Operator objects are arranged according to computer execution sequence, and it is specific to obtain center linear table:
S101: traversal rule monitoring model successively determines the element type of the formula element in regularization monitoring model.
It should be noted that in actual operation, can by elder generation according to the sequence of traversal by regularization monitoring model
Each formula element is set in turn in original linear table, then by traversal original linear table, is successively determined in original linear table
The element type of formula element realizes the purpose of traversal rule monitoring model, and different formula elements is corresponding when according to traversal
Element type, it is corresponding to execute step corresponding in S102~S112.
S102: if current formula element is that signal or constant are protected in target control, by target control protection signal or often
Number is set to center linear table tail portion, and jumps to S101.
It should be noted that this step is when current formula element is that signal or constant are protected in target control, by target
Control protection signal or constant are set to center linear table tail portion.Center linear table tail portion is set to refer to current formula member
It is to be arranged successively write-in according to sequencing when element is set in center linear table.
S103: if current formula element is function object or left bracket, converting stack for function object or left bracket indentation,
And jump to S101；
S104: if current formula element is right parenthesis, successively pop-up converts the element in stack and is set to center linear
Table tail portion, until converting the element of the stack top of stack as left bracket or function object；
S105: if the element of stack top is left bracket, left bracket and right parenthesis are abandoned, and jump to S101；
S106: if the element of stack top is function object, abandoning right parenthesis, from conversion stack pop-up function object and by function
Object is set to center linear table tail portion, jumps to S101.
Specifically, function object or a left side are included by when detecting current formula element is function object or left bracket
Number indentation conversion stack；When detecting current formula element is right parenthesis, successively the element in pop-up conversion stack and it is set to
Between linear list tail portion, until convert stack stack top element into left bracket or function object；If also, the element of stack top includes for a left side
Number, then abandon left bracket and right parenthesis；If the element of stack top is function object, right parenthesis is abandoned, pops up function from conversion stack
Function object is simultaneously set to center linear table tail portion by object.The parameter in function object can be extracted, and removes bracket.
S107: if current formula element is operation object, further judge whether the element of stack top is operator pair
As；
S108: if it is not, current formula element is then pressed into conversion stack, and S101 is jumped to；
S109: if so, further judging whether the calculating priority of current formula element is greater than the operator pair of stack top
The calculating priority of elephant；
S110: if more than current formula element being then pressed into conversion stack, and jump to S101；
S111: it if being not more than, successively pops up the operation object of stack top and is set to the operation object of stack top
Between linear list tail portion, until stack top be calculate priority be less than current formula element operation object or stack top be left bracket or
Stack top is function object, current formula element is pressed into conversion stack, and jump to S101.
Specifically, if the element of stack top is not operation object, indicating stack when current formula element is operation object
The element on top is function object or left bracket, therefore by current formula element, i.e. stack is converted in operation object indentation.If stack top
Element is also operation object, then needs whether the calculating priority of further more current formula element is greater than the element of stack top
Operation object priority: if more than, then by current formula element be pressed into stack；If being not more than, the operation of stack top is popped up
Symbol object is simultaneously set to center linear table tail portion, at this point, current formula element is still operation object, it is therefore desirable to continue into
Row judgement, until the calculating that stack top is less than current formula element for the calculating priority of operation object and the operation object is excellent
Perhaps stack top is left bracket or when stack top is function object first grade, stops the element of the stack top of pop-up conversion stack, and will be worked as
Preceding formula element indentation conversion stack.
S112: if regularization monitoring model traversal finishes, successively pop-up converts the element in stack and is set to medium line
Property table tail portion, obtains center linear table.
It is understood that after the element type for judging current formula element, it will be according to the member of current formula element
Plain type executes step corresponding in S102~S112.Meanwhile current formula element is set by next formula element, continue to sentence
The element type for updated current formula element of breaking.When regularization monitoring model traversal finishes, then successively stack is converted in pop-up
In element and be set to center linear table tail portion, obtain center linear table.
Signal, function specifically are protected into the constant in regularization monitoring model, target control the present embodiment provides a kind of
Object and operation object are arranged according to computer execution sequence, and the method for obtaining center linear table can be by different rules
The formula element changed in monitoring model is arranged according to computer execution sequence, the subsequent operation for calculating monitoring threshold of being more convenient for.
Fig. 4 is to be pressed in a kind of state monitoring method step S35 of DC control and protection system shown in Fig. 2 using calculating stack
It is calculated according to linear table element of the execution sequence to intermediate linear list tail portion, obtains the process schematic of monitoring threshold.It is above-mentioned
On the basis of embodiment, the present embodiment has done further instruction and optimization to technical solution, specifically, as shown in figure 4, S35:
It is calculated using stack is calculated according to linear table element of the execution sequence to intermediate linear list tail portion, obtains the mistake of monitoring threshold
Journey specifically includes:
S201: traversal center linear table successively determines the element type of the linear table element in center linear table.
Specifically, it is similar with traversal rule monitoring model, it first determines whether in center linear table positioned at the current of gauge outfit
The element type of linear table element executes subsequent after the element type for determining current linear table element according to definitive result
Corresponding operation, then current linear table element is set by next linear table element, continue to execute determining current linear table element
Element type the step of.
S202: if current linear table element is that signal or constant are protected in target control, by target control protect signal or
Constant indentation calculates stack, and enters traversal center linear table, successively determines the element class of the linear table element in center linear table
The step of type；
S203: if current linear table element be function object or operation object, successively from calculate stack in pop up and letter
The corresponding linear table element of the number of arguments of number object or operation object；
S204: after the linear table element inverted sequence successively popped up, being calculated using function object or operation object, will
Calculated intermediate result indentation calculates stack, and enters traversal center linear table, successively determines the linear list in center linear table
The step of element type of element；
S205: if center linear table traversal finishes, monitoring threshold is set by the intermediate result calculated in stack.
Specifically, the present embodiment is using calculating stack as the intermediate result for calculating the linear table element in center linear table
Intermediary, for storing the intermediate result calculated.
Specifically, if current linear table element is that signal or constant are protected in target control, since signal is protected in target control
Or itself is a intermediate results for constant, therefore directly protect signal or constant indentation to calculate stack target control.Current
When linear table element is function object or operation object, then and function object or operation object successively are popped up from calculating stack
The corresponding linear table element of the number of arguments utilize function object or operation after the linear table element inverted sequence successively popped up
