Abstract
The present invention provides a kind of one key sky of gasification furnace sequence examination control method: in the configuration software of gasification furnace driving sequence SIS system bottom, selection logic function block calls all practical driving conditions simultaneously or all empty examinations is called to force driving condition simultaneously, when selecting the empty examination of no load test to force, the empty examination of triggering selection logic function block output is closed by the key sky runin being set in the next configuration software and forces driving condition, driving sequence is made to meet empty strip part automatically.The invention enables process operator is changed into one key operation of operation interface in program backstage constrained variable by system engineer, many and diverse technical work is changed into simple technological operation, security risk is reduced, improves work efficiency.
Description
Technical field
The invention belongs to gasification furnace automation fields, and in particular to gasification furnace no load test control method.
Background technique
According to the operating instruction of coal water slurry gasifying device, gasification furnace must all carry out no load test before feeding intake every time,
Referred to as empty examination.The purpose is to ensure that important control valve and SIS system interlock logic are in serviceable condition before gasification furnace feeds intake.But gas
Change before furnace feeds intake, since most of running device is inactive, most driving conditions are in abnormal condition, and driving sequence can not be by
Normal step sort run, influences empty examination.Currently, most domestic enterprise do gasification furnace sky examination when, by system engineer in program
All driving and parking conditional forces are assigned to normal value by backstage, to meet empty strip part.Since driving variable is more, in program backstage
Position dispersion, system engineer are heavy workload, error-prone in pressure assignment；When cancelling pressure assignment, it is easy to omit, makes
At security risk.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of one key skies of gasification furnace sequence to try control method.
In order to achieve the above objectives, the invention adopts the following technical scheme:
In the configuration software of gasification furnace driving sequence SIS system bottom, setting can call all practical driving items simultaneously
Part calls all empty examinations to force the selection logic function block of driving condition simultaneously, passes through gasification furnace driving sequence SIS system
When the button operation sky examination of operation screen, triggering selection logic is closed by the key sky runin being set in the next configuration software
The empty examination of functional block output forces driving condition as sequence driving condition, and driving sequence is made to meet empty strip part automatically.
Preferably, when terminating empty examination by the button of the gasification furnace driving sequence SIS system operatio picture, a key
Empty runin closes triggering selection logic function block and exports practical driving condition as sequence driving condition, to carry out practical driving.
Preferably, the no load test in the key sky runin pass and gasification furnace driving sequence SIS system operatio picture
Button is associated.
Preferably, the no load test button is invisible after gasification furnace driving, and the button is aobvious after gasification furnace parking
Show and can operate.
Preferably, no load test button, selective " sky examination pressure " or the dialog box pop-up of " sky examination releases " are pressed, when
When selecting " sky examination is forced " and clicking execution, no load test button shows " interlocking sky examination is forced " printed words；When selection " sky examination solution
Except " and when clicking execution, no load test button shows " the empty examination of interlocking releases " printed words.
Preferably, when selection " sky examination force " and when clicking execution, no load test button becomes red, when selection is " empty
Examination releases " and when clicking execution, no load test button becomes green.
The beneficial effects of the present invention are embodied in:
The invention enables be changed into process operator in operation interface in program backstage constrained variable by system engineer
One key operation.Process operator only need to click button in operation interface and select to execute " the empty examination of interlocking is forced " in sky examination
State, had sky strip part call and meet in one key of program backstage, and technologist can carry out empty examination.The present invention is many and diverse
Technical work is changed into simple technological operation, reduces security risk, improves work efficiency.
Further, it after sky examination, again taps on button and selects to execute " the empty examination of interlocking releases " state, it can a key
Automatic cancel is forced, and feeds intake state into the preparation actually driven.
Detailed description of the invention
Fig. 1 is that gasification furnace no load test button corresponds to dialog box schematic diagram.
Fig. 2 is that the next Configuration principle figure is closed in one key sky runin of gasification furnace.
Fig. 3 is that front and back gasification furnace SIS system gasification furnace B driving sequence picture comparison diagram is arranged in a key automatically.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and examples.
(1) increase no load test button in gasification furnace driving sequence SIS system operatio picture, as shown in Figure 1, Figure 3.
The button is pressed, " sky examination is forced " or " sky examination releases " may be selected in the dialog box of pop-up, when selection " sky examination is forced " and is clicked
When execution, which becomes red, display " the empty examination of interlocking is forced " printed words；It, should when selection " sky examination release " and when clicking execution
Button becomes green, display " the empty examination of interlocking releases " printed words.
(2) no load test button attribute is set, keeps it invisible after gasification furnace driving, i.e., only stops in gasification furnace
The button shows and can operate afterwards.
(3) in the configuration software of gasification furnace SIS system bottom, increase by a key sky runin and close, make it through the mode of communication
It is associated with no load test button (i.e. a key sky in Fig. 2 tries button) in SIS system operatio picture.
(4) as shown in Fig. 2, in the configuration software of gasification furnace driving sequence SIS system bottom, logic function block is selected simultaneously
All practical driving conditions, empty examination is called to force driving condition, when selecting the empty examination of no load test to force, key sky examination
Switch triggering selects the empty examination of logic function block output to force driving condition, and driving sequence is made to meet empty strip part automatically；Work as selection
When the empty examination of no load test releases, a key sky runin closes triggering selection logic function block and exports practical driving condition, to carry out
It is practical to drive.
Front and back is arranged in one key automatically, and the comparison of gasification furnace SIS system driving sequence picture is as shown in figure 3, wherein have deeper
The variable assignments of gray scale background is green in operation screen actual displayed.
Advantages of the present invention is described as follows:
(1) present invention is easy to operate compared with hand-operated forced, does not need system engineer's cooperation, process operator
It can complete independently.
(2) it present invention alleviates the burden of system engineer and process operator, reduces because maloperation causes accident
Risk.
(3) hand-operated forced each empty examination needs 60-120 minutes, and empty examination 20-30 minutes can be complete every time after present invention application
At greatly improving working efficiency.
Currently, the present invention has been successfully applied in the no load test before gasification installation gasification furnace is driven, for other
The gasification furnace no load test of device is equally applicable.
