Below with reference to a specific embodiment, the present invention will be further described:
Present system includes control logic designer and algorithm actuator, and user can be by the control logic of the systemDesigner automatically designs, develops and the control logic figure of running equipment drive control device, and runs institute by algorithm actuatorState control logic figure.The input terminal for only needing for the user's control instruction of former engineering system to be linked into the system when use, by thisThe specified output point that is physically entered of system drive triggering executes corresponding operation.
The control logic designer is mainly used for: the control logic figure of design and editing equipment drive control device, simultaneouslyThe control logic template of many general is provided, is called for user flexibility, and data interaction interface is provided, for reading former engineering departmentThe user's control of system instructs, and is connected to corresponding input terminal unit module, the equipment includes that switching value equipment and analog quantity are setStandby two major classes type, the logic chart of the device drives controller are made of (such as Fig. 4, for one kind unit module, connecting line and arrowThe exemplary diagram of general control logic template), for the Logical Configuration information of storage equipment drive control device, and dynamicallyShow the calculating data of each unit module, can also by independently increase, delete with the computation sequence of adjustment unit module comeThe control function for modifying logic has the characteristics that programming is simple, it is restructural to calculate transparent and logic.Wherein, each unit moduleInside comprising specific algorithmic function for calling, it is external can intuitive, dynamically display module lower label and current value, andThe lower label of each unit module can customize, lower label to distinguish multiple similar unit modules in control logic figure,And the lower label of similar unit module cannot repeat in same logical circuit, the control logic figure under operation,With the current value of each unit module of real-time display, when output valve is analog quantity, its current value can be shown with number, works as outputWhen value is digital quantity, other than showing its current value with 0 or 1, also distinguished using different colors.
Since different equipment is physically entered output point or identical or different in the certain technical process of industrial production,Output point is physically entered with different same equipment is in different technical process.Input/output signal is different,The function that switchgear is realized is different therewith, so that control logic is also not quite similar, therefore general control logic template isIt is designed on the basis of analyzing logical relation between each input/output signal.The logic of distinct device drive control is different mainIt is different with output order to be embodied in input instruction, therefore control logic template can be according to switching value and analog quantity equipment and its defeatedEnter output point to presort, specifically, being to control according to the used type for being physically entered output point and quantity differenceSwitching value equipment and analog quantity equipment involved in system are classified, and are realized according to common switching value and analog quantity equipmentFunction, further the difference for being physically entered output point logically function needed for it is classified.With switching value equipmentFor, it is mono- defeated can be divided by single input-according to the difference of used input and output vertex type sum number amount for switching value equipmentOut, Double input-double output, single input-dual output, dual input-four seed types of mono- output；It can be according to common switching value equipment instituteThe function of realization can be inputted output point and be further divided into state feedback, from control logic to physical equipment or simulation modelThe order of sending orders achievable function under the condition generated, the function of realizing by manual operation, auto state, hasProtect several major class such as the function of equipment, the equipment state signal of ON/OFF time-out alarm signal and reflection equipment current state.
Control logic template provides one group of conventional device drives control function in the present invention, answers in practical engineering projectUsed time can handle each corresponding relationship for being physically entered output point well, so that inhomogeneity according to the difference of site technique demandBetween other device drives control logic can mutually inversion of phases without influence control process, to realize the flexible Application of template.
By taking the electronic door equipment of certain desulphurization system as an example, which is Double input-double output equipment, develops the device drives controlWhen logic processed, the general controls template of Double input-double output equipment both can be used, it can also be general in single-input-single-outputOn the basis of controlling template, realized by correctly corresponding to input and output point.Specifically, single input type switching value equipment, oneAs to show as open state negated negated as open state as off status or off status；Single output type switching value equipment, generallyOnly one start stop command is shown as, instructs and is opened for 1 equipment, otherwise closed.Double input-double output switching value is setStandby, open/close state can also be used as off status or the negated conduct open state of off status to realize by the way that open state is negated, becauseThis can be handled such equipment as the equipment of single-input-single-output type, not only make control logic more succinct in this way,And reduce the quantity that output point is physically entered used in control logic.
In the present invention when control logic stencil design, in the case where being improved for assurance function, reduce to the greatest extent usedIt is physically entered the quantity of output point, while clear, easy-to-use external interface being provided and calls, debug for system.For example, being set for certainThen standby general control logic is assigned to target under difference by the way that several identical input signals are merged into the same signalTemporary digital amount or analog quantity unit module, it is possible to reduce the workload of input data point subscript modification, and see on the whole,Also the quantity of input and output point used in logic can be effectively reduced.
The control logic template use process is as follows:
Step S1, the demand for control of analysis system specifies the logical relation between user's input/output control command, judgementWhether there is the template that can directly use, if so, calling corresponding logic control template, enter step S3, otherwise, into stepRapid S2；
Step S2, judge whether existing template meets control function demand, if so, entering step S3, otherwise, chooseThe close logic control template of one function, is deleted, the company of adding unit module or adjustment unit module on its basisThe method for connecing sequence is reconstructed logic control template, modifies, enters step S3；
Step S3, by the Logical Configuration system access containing the control logic figure editted into former control systems engineering (CSE), togetherWhen ensure system user's control instruction it is corresponding with the input end interface of control logic figure；
Step S4, operation control system, the operating condition of the internal element module of observation device drive control logic chart, andDebugging in time.
The algorithm actuator is mainly used for executing the logical algorithm of device drives controller, and operation result data are closedBe linked to it is corresponding be physically entered on output point, which, which can be loaded into, has certain fortune including PC, industrial personal computer or PLCIn the calculating device of calculation ability, the algorithm actuator has been internally integrated a middleware component, is used for device drives controllerControl logic algorithm be converted into the executable program that different hardware platforms and its instruction system are supported, pass through middleware componentIt is run after being converted to current executable program, to effectively improve control logic program between different type hardwarePortable and sharing capability.
