Abstract
Present invention discloses a kind of cement kiln automatic control system method for handover control, when DCS system, which is received, is converted to the switching signal of manual manipulation mode by cement kiln automatic control system steer mode, manual manipulation mode is converted in the case where meeting following all conditions, is otherwise alarmed；Condition 1, cement kiln automatic control system normal operation；Condition 2, each control parameter for being manually entered into the DCS system each control parameter error for being currently delivered to DCS system corresponding to cement kiln automatic control system are within the set range.The present invention can effectively improve the configuration speed of switching control program, reduce difficulty, enhance the safety of handover operation, keep smooth operation switching.
Description
Technical field
The present invention relates to building material cement clinker production of intelligent control fields.
Background technique
With the development of system optimizing control and computer technology, traditional industries intellectualized reconstruction is carried out steadily, uses
The system (expert system) that computer carries out intelligent monitoring and operation to manufacture of cement has been applied successfully in multiple factories.Traditional
The case where DCS system operation is operator's manual operation, and there is no operation switchings, even PID control, switching is also by being
It is completed inside functional block of uniting.It is that DCS system controls the inevitable choice to distil, therefore two systems control process using expert system
In no-harass switch be the technical barrier that must be solved.
When normal operation, control loop is typically in operator's manual operation state, has the condition of coming into operation in expert system
When, control loop is cut expert system control by operator, and when switching need to judge that expert system setting value and current manual are set
Whether value is consistent, and deviation, then do not allow to switch if it exists, and in addition when expert system breaks down, system will be automatically switched to
Manual operation state.Two systems setting value is switched over if any big deviation pressure will cause very big disturbance, lead to system
Biggish fluctuation.
Summary of the invention
It is a kind of when expert system control is with switching is manually controlled the technical problem to be solved by the present invention is to realize, it can
Guarantee the control method that switching is steady and disturbance is small.
To achieve the goals above, a kind of the technical solution adopted by the present invention are as follows: cement kiln automatic control system switching control
Method processed, cement kiln production equipment are uniformly controlled by DCS system, and the DCS system is equipped with manual manipulation mode and cement kiln certainly
Autocontrol system steer mode, under cement kiln automatic control system (expert's optimization system) the steer mode state, cement kiln
Automatic control system receives the cement kiln production equipment parameter that DCS system obtains, and according to pre-set programs according to the cement of acquisition
Kiln production equipment parameter issues control parameter to DCS system；
Believed when DCS system is received by the switching that cement kiln automatic control system steer mode is converted to manual manipulation mode
Number when, manual manipulation mode is converted in the case where meeting following all conditions, is otherwise alarmed；
Condition 1, cement kiln automatic control system normal operation；
Condition 2, each control parameter for being manually entered into DCS system are corresponding to cement kiln automatic control system currently to be conveyed
To DCS system each control parameter error within the set range.
The setting range of the error of the condition 2 is the 5% of current parameter value.
The alarm includes the prompt tone that alarm sound and prompt are unable to switch reasons.
Manual manipulation mode is manually entered control parameter by operation panel, manipulates mould when executing cement kiln automatic control system
When formula, the fluctuation situation of each control parameter of DCS system is delivered to according to cement kilns automatic control system, to each control
One intermediate variable of parameter definition processed, in the real-time assignment to operation panel of intermediate variable that current each control parameter is defined.
When executing cement kiln automatic control system steer mode, operation panel is manually entered as failure state.
The present invention can effectively improve the configuration speed of switching control program, reduce difficulty, enhance the peace of handover operation
Quan Xing keeps smooth operation switching.
Specific embodiment
When no-harass switch is that same control loop is controlled by two systems, when carrying out control switching, keep setting
The continuity of definite value reduces disturbance, steady to switch.Since a system has multiple control loops, by no-harass switch function
Integrated it can be packaged into custom feature block, facilitate application, do not need the switching journey that each control loop edits a set of complexity
Sequence.
Whether 1. MANUAL CONTROL mode: this is conventional operator's control model, only setting value need to be judged in range ability
It is interior, if the value of operator's input is below or above range, then it is assumed that be invalid value, do not allow to input.In this operation mode
Under, expert's Optimal Control System tracks DCS system in time and manually sets value.
2. expert system control mode: operator can be by being individually switched button on a key switching pin or operation panel
Switching is carried out, certainly, switching function is can just to carry out in the case where expert's Optimal Control System operates normally, while needing to meet
Current output value is consistent with expert system calculated value, if deviation is larger also not to be allowed to switch, deviation default setting 5% should
Numerical value can be modified according to on-site actual situations by system manager, be simultaneously emitted by alarm and voice prompting.In expert system
When control, define an intermediate variable, expert system setting value be assigned to the intermediate variable, activation DCS manual operation value with
The track intermediate variable, operator is failed by operation panel input value at this time；When manually controlling, DCS manual operation value with
Track intermediate variable disabler, the numerical value that activation operator inputs from operation panel.Ensure expert system by function setting
Control, in failure or manual switching held stationary switching consistent with DCS manual control data.
