The realization of a corresponding informatization means, namely a water engineering combined dispatching system, and the optimization calculation result of the dispatching scheme have important significance for providing support information for flood control and disaster reduction dispatching decisions.
The management and implementation of the scheduling rules in the water engineering combined scheduling system are one of the difficulties in system implementation, in the traditional water engineering combined scheduling system, the scheduling rules are mostly implemented in a program hard coding mode, namely, the scheduling rule calculation is implemented through program logic, the scheduling rules in the hard coding mode are implemented to prevent flood and can not be increased, decreased or modified at any time in the later period, the scheduling effects in different water engineering application scenes can not be effectively researched, the actual application requirements of water engineering combined scheduling can not be effectively met, and the practicability of the scheduling application system is greatly reduced. For example, the reservoir can discharge 1000m when reaching flood limit water level3S is the default scheduling rule written in the program by hard coding, if the user wants to know about flood discharge 500m3The scheduling operation effect of/s requires adjusting the scheduling rule by modifying the program code, which is obviously not practical in practical application.
The expression, analysis and calculation of the scheduling rules are also difficult to implement in the scheduling system. In the existing similar application system, the condition of the scheduling rule is partially realized according to a logic tree (such as the scheduling rule management in the one-dimensional flood analysis software MIKE11 of DHI), the method indicates that the scheduling rule has the problems that a user is difficult to understand and the system is difficult to realize, meanwhile, the calculation efficiency is not high enough because the logic condition needs to be analyzed in each scheduling calculation, and when reservoir engineering joint optimization scheduling calculation needs to be carried out (thousands of scheduling rule calculations may need to be carried out), the calculation efficiency is difficult to meet the actual application requirements. In the aspect of expression of scheduling conditions, a function similar to field query of ArcMap software of the Esri company expresses a retrieval condition in a 'conditional expression' mode, and a 'condition' part of a scheduling rule is expressed in an expression mode.
In summary, the following problems exist in the prior art:

Detailed Description
The first embodiment is as follows:
a water engineering combined scheduling method comprises the following three steps:
the method comprises the following steps: and (3) formal analysis: collecting weather forecast and flood forecast data, judging whether water engineering joint scheduling is needed, and if so, sequentially executing the second step and the third step;
step two: forecasting and calculating the water coming from the section: calculating the water inflow condition of the section according to the rainfall condition and the upstream water inflow condition;
step three: performing water engineering combined dispatching calculation according to section water inflow forecast: performing water engineering joint scheduling calculation analysis through a water engineering joint scheduling system, wherein the water engineering joint scheduling system takes specific water incoming conditions and scheduling rules as input conditions and outputs a scheduling scheme; the water engineering combined dispatching system comprises a plurality of dispatching rules, wherein any dispatching rule is divided into a dispatching condition and a dispatching operation, and the dispatching condition is expressed by adopting a condition expression; before the calculation of the scheduling rules, dynamically compiling any plurality of scheduling rules into executable codes according to a specified calculation mode and a program interface, wherein the executable codes are a series of function pairs, and the function pairs consist of scheduling condition functions and scheduling operation functions; the object attribute values in the scheduling conditions and scheduling operations are directly replaced by the object index in the memory during compiling.
And in the third step, a water engineering joint scheduling system is adopted to carry out water engineering joint scheduling calculation analysis, and in order to realize dynamic management and efficient calculation of scheduling rules, the improvement of the scheduling rules part comprises three main steps, namely dynamic expression and management of the scheduling rules, dynamic compilation of the scheduling rules and calculation of the dynamic scheduling rules. The overall flow chart of the embodiment is shown in fig. 1.
1. Expression and management of scheduling rules: the invention defines any scheduling rule in the water project joint scheduling system as a 'condition-operation' part, when the 'condition' is satisfied, the system executes corresponding 'operation', and when the 'condition' is not satisfied, the 'operation' is not executed, corresponding to the scheduling rule of the actual water project joint scheduling service. If' the water level of a certain reservoir reaches the flood limit water level, the flood discharge gate is opened to discharge the flood for 200m3And/s 'under the condition that the water level of a certain reservoir reaches the flood limit water level, and correspondingly, the corresponding operation is' opening the flood discharge gate to discharge 200m3And/s', acquiring the attribute of the corresponding object in the scheduling application system to judge (namely, judging the condition), and setting the state value of the project (namely, scheduling the operation). In actual business, it is possible that the scheduling conditions may be complicated, such as "when the upstream reservoir is lower than the flood-control high water level and the downstream water level is higher than the warning water level, or when the upstream reservoir is higher than the warning water level, the reservoir keeps the discharge amount of 300m3S ", scheduling the" bar "at this timeA piece "is a logical combination of several basic" conditions ". There is also an unconditional scheduling rule, for example, "reservoir level is kept below 150 m", and "condition" is null, indicating that "condition" determination is always true. The scheduling rule can be expressed as two parts of "condition-operation" in a canonical form, where the form of "operation" is relatively fixed and is a modification to the state of the scheduling object, and the "condition" part is relatively complex and may be a combination of multiple basic "conditions".
In this embodiment, a normalized form expression of a scheduling rule is defined, one water engineering joint scheduling calculation scheme includes any multiple scheduling rules, and one scheduling rule can be divided into two parts, namely, a conditional expression and scheduling control (i.e., scheduling operation, the same applies below), in the following form:
R＝{Ce，{O，AoOP, V } } equation 1
Wherein R represents a scheduling rule, CeIs the scheduling condition, { O, AoOP, V represents dispatch control, O represents an object to be controlled, such as a certain reservoir; a. theoAn attribute (or state) of the controlled object, such as a current water level of the reservoir; OP represents an operation symbol, e.g. to control the discharge of a reservoir to below a certain value (the mathematical symbol is) "<"); v denotes a specific operating value, e.g. control leakage not higher than 1000m3And/s, then 1000 is the operating value. CeThe scheduling condition may be relatively complex, so the present invention is expressed in the form of an expression, and an example of the scheduling condition expression is as follows:
([ # horizontal head |50700401#) ] [ water level ] >56 or [ # six safety hydrological station |958311QX #) ] [ water level ] >67)
And ([ # buddhist ridge reservoir |50701000#) ] [ water level ] <120)
Wherein "[ # horizontal head |50700401#) ] represents the horizontal head section object, and the coding after the" | "symbol is used for ensuring the uniqueness of the water engineering object (preventing the water engineering object name from being possibly repeated); "[ water level ]" indicates the "water level" attribute of the horizontal row head. The meaning of the conditional expression of the entire scheduling rule is that the "when the water level of the horizontal row head is higher than 76m or the water level of the six ampere hydrological stations is higher than 67m, and the water level of the budding ridge reservoir is lower than 120 m" condition "is satisfied to perform the corresponding operation. In the mode, the conditional expressions can be combined arbitrarily through brackets and logic expressions to realize the expression of various complex scheduling conditions. The conditional expressions can be managed by the implementation of the application software of the application system to facilitate the user's scheduling rules (see fig. 2), and the objects and attributes can be entered by selection. Compared with a management mode based on a logical tree (such as fig. 3), which needs to manage scheduling conditions through a logical hierarchical relationship, a condition and condition combination relationship, a combination relationship of condition and condition grouping, and the like, the interface is complex, and users are difficult to understand, the management mode of the scheduling rule is easier for users to understand and the application system is easier to implement.
2. Dynamic compilation of scheduling rules: the dynamic compiling of the scheduling rule is divided into two functions, wherein one function is to dynamically compile the conditional expression to mainly solve the problem of computational efficiency, and the other function is to dynamically compile according to a certain interface to form a computing mode of the scheduling rule, so that the dynamic management of the scheduling rule is supported.
The method compiles the conditional expression into an executable code in a dynamic compiling mode before the calculation of the scheduling rule, and compiles the related objects in the scheduling 'condition' into the memory index of the object, so that the conditional expression does not need to be analyzed and the value of the object does not need to be searched when in scheduling calculation, and the calculation efficiency is high. In this mode, the conditional expression can be simply converted into a program statement (the logic expression is basically the same as the program statement) during compiling, the application of complex scheduling 'conditions' is supported, the calculation efficiency is high (the expression is analyzed without calculation), and the requirements of functions and performance of the water engineering combined scheduling application system are met.
The method dynamically compiles the scheduling rules into executable codes according to a certain program interface form to form a calculation mode of the scheduling rules, thereby supporting the dynamic management and the efficient calculation of the scheduling rules. The program interface means that a type of objects of the system have the same function or attribute according to a certain specification, and can be recognized and called by the system according to a certain mode (if the objects are loaded and called through a reflection mechanism). Because the scheduling rule can be divided into two parts of a conditional expression and scheduling control (namely scheduling operation), the scheduling rule can be defined into a series of objects (the invention is a 'function pair', namely two functions in pair correspond to a 'condition' part and an 'operation' part respectively) according to a certain interface, and thus, the loading and execution of any plurality of similar objects are supported, the loading and execution of any plurality of scheduling rules are supported, and the calculation mode supporting the increment, the decrement and the modification of the scheduling rule is formed without modifying codes. The dynamically compiled scheduling rules form executable code (assemblies) and structures of the following patterns within the application system.
{Gf，OPf，{RkH, where k is 1,2 … … n, equation 2
In the above formula, GfAnd OPfTwo methods for software device presetting in this embodiment, GfIn order to obtain a uniform function method of object attribute values, a water engineering object and attribute (which are fixed format objects and attribute indexes in a memory) are obtained by the method during calculation of each scheduling rule; OP (optical fiber)fA unified function method for scheduling operation calls a related scheduling operation service method of the water engineering joint scheduling system (an application system can define different scheduling operation service methods according to different water engineering objects and does not belong to the coverage range of the invention); { RkThe scheduling rules are formed after dynamic compilation, and each scheduling rule corresponds to one Rk. Each RkComprising a pair of functions, each being a scheduling condition function (Fcondition)k) And scheduling operation function (Fcontrol)k) As shown in the following formula.
Rk＝{Fcontrolk，FconditionkEquation 3
Scheduling Condition function (Fcondition)k) Is generated after the conditional expression is analyzed (wherein the object and the attribute are replaced by G)fMethod), scheduling operation function (Fcontrol)k) The code of (2) has scheduling operation related information analysis generation (mainly by calling OP)fA method to implement).
To better illustrate the computing modes and software settings to implement dynamic schedulingA rule program is an example. The 'function pairs' of a series of compiled scheduling rules are packaged in a class named RuleExcutor Runtime (see FIG. 4), and each scheduling rule generates a 'function pair' (R)k) Fcontrol thus generatedkMethod and FconditionkThe method also has a number, and functions in the actual code, such as control function1() and RuleFunction1(), are used for realizing the related functions of the scheduling rules and calling the efficient calling of the objects (i.e. the communication of the scheduling rules part with other parts of programs, such as obtaining the scheduling objects and the attribute values). The invention defines an IRuleProcessor interface which needs to realize GfAnd OPfThe two methods are used for obtaining attribute values of the scheduling related water engineering objects and controlling the scheduling related water engineering objects respectively, when the RuleExcutor Runtime object is called, the object for realizing IRuleProcessor is transmitted, and the RuleExcutor Runtime object can pass through the IRuleProcessor (G) two methodsfAnd OPf) And acquiring the attribute value of the object in the memory and controlling the related scheduling object, thereby realizing the communication between the scheduling rule program and the main scheduling program.
The dynamic compiling of the scheduling rule requires a program language to support the dynamic compiling function, but most high-level languages support the dynamic compiling technology, such as C #, Java, and the like, and the embodiment is implemented by using C # speech. Through the management and compiling mechanism of the scheduling rules, any number of scheduling rules can be added in an application system, so that the dynamic management of the scheduling rules is realized; the compiled code does not need to analyze the scheduling condition in the scheduling calculation, and the calculation efficiency is also very high.
3. And (3) calculating a scheduling rule: as described above, the scheduling rules have been compiled into executable code (RuleExcutorRuntime object) prior to the computation of the water engineering joint scheduling scheme. In the example of fig. 4, the implementation object of the IRuleProcessor interface includes two methods, namely GetConditionVal and ControlAction, and the method GetConditionVal (i.e. G)f) The parameter objid represents the number of the object in the memory, the parameter attembutid represents the attribute number of the object, and the specified attribute value of the specified water engineering object can be obtained; method ControlAction (i.e., OP)f) Represents the object to be controlled by the parameter ojbidThe number, attenbuteid represents the attribute number of the object to be controlled, optype represents the control operation type (such as "greater than", "less than", etc.), valpara represents the value of specific control, and the scheduling control of the water engineering object can be realized. Scheduling condition function RuleFunction (i.e., Fcondition)k) The GetConditionationVal (i.e., G) will be called from an object implemented by the incoming IRuleProcessorf) Acquiring the value of a required object in the conditional expression; scheduling operation function ControlFunction (i.e., Fcontrol)k) An object realized according to the incoming IRuleProcessor calls a controlAction (namely OP)f) And carrying out scheduling control. The communication between a caller and a called object is realized through a mutual calling mechanism, so that the object value is quickly acquired from the memory and the related control is performed by the function pair of the scheduling rule. The relationship between the dynamically compiled set of scheduling rules and the caller is shown in FIG. 5.
When the water engineering scheduling scheme is calculated, the calculation of the scheduling rule is embedded in each calculation step, namely the calculation of the scheduling rule is called in each calculation process. The calculation process of the scheduling rule mainly comprises the following steps: loading a program set, and constructing an object of any class in the running state of the program through a reflection mechanism (the reflection mechanism refers to that the object of any class can be constructed, the class to which any object belongs can be known, member variables and methods of any class can be known, and the attribute and the method of any object can be called; C #, Java and other high-level languages have reflection mechanisms); acquiring a scheduling rule list; and executing 'function pair' of the scheduling rule. The whole execution flow of the scheduling rule is shown in fig. 6. It should be noted that, when the "function pair" of the scheduling rule is executed, two types of scheduling rules are distinguished, one type is a conditional scheduling rule, and the other type is an unconditional scheduling rule. The conditional scheduling rule is a scheduling rule having a conditional expression, and when the condition is judged to be established, the scheduling control method is executed. The unconditional scheduling rule is a scheduling rule without scheduling conditions, and the scheduling control method is directly executed at this time (for example, the unconditional scheduling rule is used when the reservoir level must be controlled to be below the check flood level in any case). When the dispatching rule is calculated for multiple times and the water engineering joint dispatching optimization calculation needs millions of times, firstly, and secondly, the dispatching rule list is stored in a memory only by being executed once during the first calculation, and the function pair of the list is directly called for calculation at other times.
The dynamic configuration and the efficient calculation of the scheduling rules of the water engineering joint scheduling method are supported through the realization of an expression representation method of the scheduling conditions, the dynamic compiling of the scheduling rules and a scheduling rule calculation method. Through the practical use of an application system, 10000 times of calculation of all the scheduling rules of the water engineering combined scheduling scheme of the Anhui province and river basin need 3 seconds, and the calculation result is verified to be in accordance with the setting of the scheduling rules. Therefore, the implementation method based on the dynamic water project joint scheduling rule can realize dynamic management of the scheduling rule, can realize efficient calculation of the scheduling rule, lays a foundation for optimized calculation of a water project joint scheduling scheme, and has good application and popularization values.
The above embodiments are only part of the present invention, and do not cover the whole of the present invention, and on the basis of the above embodiments and the attached drawings, those skilled in the art can obtain more embodiments without creative efforts, and therefore, the embodiments obtained without creative efforts should be included in the protection scope of the present invention.
