Application of the VB scripts in cigarette dust pelletizing system is specifically described below：
By VB scripts, implement function such as：
The cigarette pressure of cigarette dust pelletizing system, cigarette pressure, supervisor's wind pressure signal, frequency converter temperature are each set respectively
For the upper limit, lower limit and state variable, and carry out logical process with VB sentences, realize that function is as follows：
1st, when monitored variable (such as：Cigarette pressure) instantaneous value be in the upper limit (such as：5000MPa) and lower limit (such as：
Outside scope 4000MPa) (such as：Instantaneous value is 5500MPa), corresponding alarm code will be triggered, then warning system will
Its state value is changed to by exception according to alarm code, while triggers audible alarm and word warning message.
2nd, when having set arranges value (upper lower limit value) every time, " preservation " button is pressed, will be triggered by VB sentences will alarm
All variate-values are stored in outside excel documents in system (the document needs to establish in outside specified path in advance)；
3rd, when pressing " reading " button, will be triggered by VB sentences by all variate-values in warning system by outside excel
The last setting value of document (the document needs to establish in outside specified path in advance) is covered；
4th, it is automatic to read last time setting value when warning system starts；
5th, cigarette pressure, cigarette pressure are one of conditions of work of cigarette machine, are mainly provided for cigarette machine suitable outer
Table air pressure makes it obtain stable service behaviour.Currently in order to cigarette machine is set to obtain stable performance, typically by power houses
Dust pelletizing system supplies.Because every machine is influenceed by site environment, its condition of work differs, typically in 8000-12000 models
Enclose, beyond the job stability of the range effects cigarette machine.Pressure is detected by the pressure sensor on airduct, is changed
PLC is fed back to for 4-20ma analog signals.
6th, flatiron signal, air door signal, wind pressure signal are also one of condition of work of cigarette machine, are mainly used in cigarette dedusting
Whether system identification cigarette machine normally starts.At present cigarette dust pelletizing system by judge three signals whether and meanwhile meet to sentence
Whether disconnected cigarette machine is normally-open.
Three signals are switching value：Flatiron signal is proximity switch, by detecting low speed flatiron position, when low speed flatiron
When falling, detection signal feeds back to PLC, illustrates whether flatiron is ready to；Air door signal is that cigarette machine air door plays opening/closing letter
Number, it is derived from the relay auxiliary contact for controlling cigarette machine discharger；Wind pressure signal is cigarette machine fan operation signal, is derived from cigarette
The auxiliary contact of machine blower fan relay.
Flatiron signal, air door signal, wind pressure signal feed back to live IO casees, then are sent to by profibus bus protocols
PLC.Then wincc reads cigarette pressure, cigarette pressure, flatiron signal, air door from PLC by Profibus bus protocols and believed
Number, wind pressure signal, the value and setting value are subjected to logic comparison finally by VB scripts, judge whether to need to trigger alarm signal
Number.
After alarm signal is triggered, wincc row can be triggered warning message in the form of digital code by VB scripts
Table control, corresponding information is exported in list control.On the other hand, D disk assigned catalogues are stored in by the contact of VB scripts
Under wav audio files, corresponding alarm voice is played out by the Windows xp player that carries.
If the 205, first number is more than the frequency threshold value of setting, alarm signal is triggered；
If first number is more than the frequency threshold value of setting, alarm signal is triggered, specifically, can be operated in the alarm
Display alarm information on interface, the warning message are provided with the link of the built-in variable value, directly passed through so as to maintain easily personnel
Built-in variable value is checked in position where warning message links to built-in variable value, improves search efficiency.
If the 206th, first number is more than 0 and less than the frequency threshold value of setting, feedback interference prompt message；
If first time number is more than 0 and less than the frequency threshold value of setting, illustrate flatiron signal, air door signal or blast
One or more of signal exceeds the number of zone of reasonableness still in tolerance, at this point it is possible to such case is considered as dry
Disturb, alarmed without triggering.
207th, the device parameter and outside excel files are linked using VB scripts, and using excel files to the equipment
Parameter is preserved and read.
In addition, whenever necessary, VB scripts can be used to link the device parameter and outside excel files, and utilize
Excel files are preserved and read to the device parameter.
It should be noted that the warning system way in industry is usually to be handled in PLC, then result is passed through
Profibus is transferred to wincc, will necessarily so increase PLC burden plus bandwidth usage and wincc points.The present embodiment
In alarm method select directly in host computer terminal by way of VB scripts are handled, because all logical process all exist
Inside wincc, so can only increase the cpu loads of pc machines, but avoiding increase procedure quantity causes to increase PLC loads, increase
The problem of variable causes to increase bandwidth occupancy rate and wincc points.
It can be seen that the scheme handled from VB scripts has following advantage：
1st, PLC loads are not increased.PLC is the precious resources of industrial system, and the sentence of cpu processing is more, and sweep time gets over
Long, system response is slower.
2nd, it is not take up network bandwidth.Industrial bandwidth is valuable resource, and bandwidth load mutually restricts with transmission rate, because
The load of this data volume is often determining the reaction speed of system.
3rd, wincc points are not increased.Wincc points refer to the number of the input and output point of automated system, that is, defeated
Enter the number of output variable, it is necessary to first producer of Siemens purchase, and one of precious resources of industrial system.
A kind of alarm method of cigarette dust pelletizing system based on wincc of the present invention, it can be built by wincc automatic
Warning system realizes remote operation, reduces operating personnel's workload, improves fault reaction speed, to realize that cigarette dust pelletizing system is grown
Phase reliable and stable operation.
For ease of understanding, above-mentioned Fig. 2 is corresponded in embodiment by the code of VB scripts under an application scenarios below
Technical scheme be described, can be understood simultaneously refering to Fig. 3：
First, the variate-value in VB scripts is explained as follows：
Here variate-value is divided into：
Wincc industrial docking variate-value, wincc built-in variable value, the built-in variable value of VB (VC) global script；
1) wincc industrial docking variate-value：Established by the corresponding communication protocol in wincc variable managers
(such as tcp/ip), these variables are the variate-values for directly being contacted with PLC by communication protocol, the typically change to PLC
Amount carries out direct read/write operation；
2) Wincc built-in variable value is established by the built-in variable in wincc variable managers, is for storing
The important technical parameter information that system needs.Such as：
The actual value of FC1 unit blower fan main pipe pressures, higher limit, lower limit, state value (be used for represent the pressure whether
In normal range (NR)), these values are corresponding each to need the parameter monitored to have one group.Following program is as space is limited,
Technological parameter (fenya-FCJ) is taken dissect, remaining variable is the same processing method.
There is alarm switch state value, alarm code value etc. in addition.
3) VB (VC) built-in variable values correspond with above-mentioned value and establish connection, in VB (vc) inter-process and output
To wincc needs.
Here variate-value is including but not limited to as follows：
The signal at cigarette machine scene, including cigarette tipping pressure, cigarette cigarette receiving pressure, cigarette pressure, flatiron signal, air door
Signal；
The blast of dust pelletizing system, including FCJ unit blower fans main pipe pressure, FC1 unit blower fans main pipe pressure, FC2 unit wind
Owner's pipe pressure, FC3 unit blower fans main pipe pressure, FS1 unit blower fans main pipe pressure, FS2 unit blower fans main pipe pressure, FG units
Blower fan main pipe pressure；
Frequency converter temperature, including FCJ unit fan frequency converters temperature, FC1 unit fan frequency converters temperature, FC2 unit wind
Machine frequency converter temperature, FC3 unit fan frequency converters temperature, FS1 unit fan frequency converters temperature, FS2 unit fan frequency converter temperature
Degree, FG unit fan frequency converter temperature；

On off state, FC3 unit blower fans machine side on off state, FS1 unit blower fans machine side on off state, FS2 machines by FC2 unit blower fans machine
On off state, FG unit blower fans machine side on off state by group blower fan machine；
The processing procedure of signal is：
On-site signal is transported to wincc industrial docking variate-value by PLC by communication protocol, then VB (vc) script
By being stored in script built-in variable after reading, to carry out the processing of next step (logic judgment etc.)., will after script is disposed
Result is output to wincc built-in variable.Man-machine interface is output to finally by wincc built-in variables.
The parsing of following program segment, using the form of example, such as：
No01.JY_RUN "s ＆＆ " No01.POD_OUT "s ＆＆ " No01.AIR_ROOM_ON ", it is the industrial right of three wincc
Connect and use variate-value, direct value is in live PLC；
SetTagBit("kj",1)；Here kj is VC script built-in variables, simply participates in internal logic processing；
{if(((double)GetTagDouble"ZS_FCJ.DUCT_PRESSURE_SAMPLE")<=(double)
GetTagDouble(jd))||((double)GetTagDouble(ju)<=(double) GetTagDouble (" ZS_
FCJ.DUCT_PRESSURE_SAMPLE")))
ZS_FCJ.DUCT_PRESSURE_SAMPLE is the blast actual value of fcj dust removal units, is the industrial right of wincc
Connect and use variate-value；
Jd (down) is the blast lower limit of corresponding fcj dust removal units；Jd (up) is on the blast of corresponding fcj dust removal units
Limit value；The two are
Wincc built-in variables；This alarm system interface is corresponding with the setting of upper and lower bound for each technological parameter,
Ju and jd can be accepted in the value of man-machine interface input.
if(cj>GetTagFloat(bjsx))；Here bjsx is wincc built-in variables, for being output to man-machine interface
's.System man-machine interface has individual shift knob, exactly by controlling this variable come this warning system of start and stop.
Vc scripts realize the method automatically controlled：
1st, the newly-built vc script (titles of global script are passed through in wincc：ccbj)；
2nd, the built-in variable value in wincc is obtained by #define orders, and is given to vc built-in variable, the step
Effect be to read corresponding variate-value to inside vc from wincc, to be handled in next step；
#define ju " fenya-FCJ-up " judge whether dust pelletizing system has been switched on；
If ((" ZS_FCJ.FAN_FREQ_RUN "==" ZS_FCJ.FAN_FREQ_SET ") ＆＆ (" FC1.FAN_FREQ_
RUN "==" FC1.FAN_FREQ_SET ") ＆＆ (" FC2.FAN_FREQ_RUN "==" FC2.FAN_FREQ_SET ") ＆＆ ("
FC3.FAN_FREQ_RUN "==" FC3.FAN_FREQ_SET ") ＆＆ (" FS1.FAN_FREQ_RUN "==" FS1.FAN_
FREQ_SET ") ＆＆ (" FS2.FAN_FREQ_RUN "==" FS2.FAN_FREQ_SET ") ＆＆ (" FG.FAN_FREQ_RUN "=
=" FG.FAN_FREQ_SET "))
Wherein, // " * .FAN_FREQ_RUN " is fan frequency converter actual motion frequency；" * .FAN_FREQ_SET " is wind
Machine frequency converter setpoint frequency；
When dust pelletizing system so when the running frequency of blower fan reaches setting value, it is determined as that dust pelletizing system normally opens
It is dynamic.
SetTagBit("kj",1)；When //kj is 1, dust pelletizing system is normally-open；Otherwise system is also without just normally opened
Open or in halted state；
elseSetTagBit("kj",0)；//
4th, result is output to by wincc variable by HMIRuntime.Tags write functions and calls Windows
The method output audio of function.It can be seen that output audio meets following condition：
1st, dust pelletizing system has been switched on；
2nd, three signals of No. 1 cigarette machine meet (being that No. 1 cigarette machine normally starts) simultaneously；
3rd, No. 1 cigarette machine one of parameter (such as：It is hinged with pressure) more than the duration of limits value (bound)
More than the number (bjsx) of setting；(time about 1 second of the global script per run-down, therefore be exactly for 10 times 10 seconds, this setting
It is jamproof effect, preventing the impulse disturbances of industrial signal causes system false alarm).
The result output statement of write functions is described in above-mentioned：
1、SetTagFloat("fenya-FCJ",1.0)；This sentence changes corresponding signal colour in man-machine interface
(it is normally 0, green；Abnormal is 1, red)；
2、SetTagWord("bjdm",1)；This sentence is by the control variable of wincc list control in man-machine interface
Bjdm is changed.(when bjdm=0, system man-machine interface is shown " system is normal "；
When bjdm=1, show " FCJ wind pressure alarms "；
When bjdm=2, show " FS1 wind pressure alarms ") and so on.
4.1st, the function that following sentence is realized is：
Wind pressure signal, flatiron signal and the air door signal of cigarette machine are detected if the switch of warning system is opened, it is no
Any operation is not performed then；
If (GetTagBit (kj)==1)
{if("No01.JY_RUN"&&"No01.POD_OUT"&&"No01.AIR_ROOM_ON")
Above-mentioned code interpreter is as follows：
The wind pressure signal of No01.JY_RUN cigarette machines；
The flatiron signal of No01.POD_OUT cigarette machines；
The air door signal of No01.AIR_ROOM_ON cigarette machines；
Only when three signals of cigarette machine meet that can just be considered as cigarette machine has been switched on simultaneously；
The function that less than 4.2 sentences are realized：
When system detectio to parameter actual value (such as FCJ blast actual value) is higher than setting higher limit or less than lower limit,
When being continued above number (bjsx) of setting, alarm signal is triggered.If less than the number of setting, it will be regarded as disturbing, do not trigger
Alarm.
{if(((double)GetTagDouble("ZS_FCJ.DUCT_PRESSURE_SAMPLE")<=(double)
GetTagDouble(jd))||((double)GetTagDouble(ju)<=(double) GetTagDouble (" ZS_
FCJ.DUCT_PRESSURE_SAMPLE "))), it act as：Compare the upper lower limit value whether actual value exceedes setting.
cj++；Be delayed sentence, it is necessary to is continued above the number (bjsx) of setting
if(cj>GetTagFloat (bjsx)) if // setting number is continued above, variable fenya-FCJ is changed into
1.0.Because this variable and wincc built-in variable of the same name are attached, and the wincc built-in variable is to be used to show FCJ
The state (1.0 be normal, and 0 is abnormal) of blast, therefore warning message will be caused to be shown at wincc interfaces.
{SetTagFloat("fenya-FCJ",1.0)；
// alarm delay function is realized, for the stability of regulating system, equivalent to connection delay function；
ZS_FCJ.DUCT_PRESSURE_SAMPLE represents FCJ (dust collection blower fan) airduct actual pressure value, under jd is
Limit value, ju are higher limit, and Bjsx is the delay value of alarm settings, and jd, ju and bjsx can be in the artificial roots in warning system interface
Set according to actual conditions：When actual value exceeds bound, and the duration reaches predetermined number (bjsx), system thinks to alarm
