The automatic monitoring method of of the present invention kind of environmental contaminants, comprise the task-set, data mode identifier collection, script, routine mission method, long-distance remote-control method of oriented mission and backup method upwards, below specifically introduce the each several part and the design philosophy thereof of this method:
One, our comprehensive advanced both at home and abroad Monitoring Data quality assurance and quality control standard standard, design compilation go out the Monitoring Data status indicator symbol collection applicable to universal environment automatic monitoring of the present invention system, and rule is given in distinctive tax.Described identifier collection is as follows:
The monitoring result data are effective---and (no symbol)
Concentration data sudden change---R; Concentration data is constant---r
The super upper limit of concentration data---+; Concentration data hangs down lower limit----
Wait for sample supply (data recovery)---W
Data transmission bad connection---BB
Information characteristics with apply mechanically template and be not inconsistent---MD
Instrument and equipment off-line---D
Service condition bad (warning)---B
Check and to carry out zero point---PZ; Check that zero point is defective---PZB
In checking that span is carried out---PS; The inspection span is defective---PSB
During calibration is carried out zero point---CZ; Calibration is defective zero point---CZB
During the calibration span is carried out---CS; The calibration span is defective---CSB
In checking that precision is carried out---AS; The inspection precision is defective---ASB
In checking that zero point drift is carried out---TZS; Inspection zero point drift is defective---TZSB
In checking that the span drift is carried out---TSS; Check that the span drift is defective---TSSB
In checking that the span reappearance is carried out---TSR; Check that the span reappearance is defective---TSRB
In checking that the multiple spot span is carried out---TSL; Check that the multiple spot span is defective---TSLB
Valid data time accumulative total is not enough---H; Instrument and equipment control does not meet expectation---Dt
Correspondingly, the related instrument and equipment of monitoring project is carried out the automatic measure control operation, be fit to diversity, the complicacy of substation and support Laboratory Instruments equipment kind and integrated morphology for the Monitoring Data identifier be can be used in.It is both accurate, clear again that sign is used.The data that guarantee all monitoring projects are not lost or are misapplied, and are convenient to understand instrument and equipment running status and the on-the-spot problem that occurs.We have determined for this reason that also the identifier of following data to all monitoring projects composes to principle:
1, inefficacy principle.Sign is in case occur, must keep always, be overcome up to the problem that produces this sign, the process that perhaps produces this sign is finished, perhaps changed the instrument and equipment that breaks down, could eliminate---particularly those are about monitoring project inspection, the calibration underproof sign that neutralizes.
For example: certain checks that zero point is defective, then up to this monitoring project after this having check qualified record at zero point before, the data of this monitoring project will have the underproof sign of zero check (PZB) always.
2, priority principle.If meeting the tax of a plurality of signs simultaneously, the related instrument and equipment running status of monitoring project gives condition, then preferential in the following order selected identity:
Instrument and equipment off-line (D)---data transmission bad connection (BB)---information characteristics with apply mechanically template and be not inconsistent (MD) that------------" combined task " is defective---" simple task " is defective---waited for (W) to service condition bad (B) during " simple task " carried out during " combined task " carried out.
Wherein: " simple task " is digital examination or calibrates zero point, span, precision three generic tasks, and " combined task " is meant other inspection tasks beyond above-mentioned three generic tasks.
For example: service condition is taking place when bad, as instrument equipment also be in just carry out check, the state of the generic task of calibration, then only compose to the bad sign (B) of service condition.
And for example: in checking that the multiple spot span is carried out,, only compose and give the inspection ongoing sign of multiple spot span (TSL) though include some inspection zero point, check span processes such as (each points).
3, relevance principle.If when certain pollutant monitoring project is checked (or calibration), cause that standard substance has entered the sample delivery passage of the related instrument and equipment of other monitoring projects during instrument and equipment is integrated---for example entered the sample collecting passage, perhaps entered same sample is carried out instrument that multicomponent analyzes etc.Then those are related to, and can not keep obtaining the data of the related monitoring project of the instrument and equipment of authentic sample this moment, must compose and give the sign (W) of waiting for sample supply (data recovery).
4, share principle.If certain pollutant monitoring project is checked when calibration (or), instrument and equipment has inspection (or calibration) task of other monitoring projects in integrated just, also is to use identical with it reference material mode of movement and flow process (duration and release time).These monitoring projects then, use the inspection (or calibration tasks) of this reference material mode of movement and flow process, also equal automatically to be carried out by starting simultaneously, the data of these monitoring projects are being carried out the ongoing sign of this inspection (or calibration tasks) with regard to composing to give so.
For example: if instrument and equipment integrated in each pollutant monitoring project when checking zero point, the zero standard thing mode of movement that uses is identical with flow process, be that the related instrument and equipment of these monitoring projects can obtain the zero standard thing simultaneously and supplies with, and the inspection of these monitoring projects zero standard thing service time that task be scheduled to zero point and stop the zero standard thing and supply with that afterwards Wait-to-Restore is identical to the time of authentic sample supply.Then as long as one of them monitoring project has started inspection task at zero point, other monitoring projects also have been activated inspection task at zero point in fact simultaneously, and so, the data of each monitoring project just must be assigned to checks ongoing sign at zero point (PZ).
And for example: if what be used to prepare standard gas at air automatic monitor station point is to contain SO
2, NO, CO multiple standards thing mixing steel cylinder gas, the standard of preparing according to same dilution ratio meets SO again respectively
2, NO, CO pollutant monitoring item inspection (or calibration) span concentration requirement, and under specific plenum system, can flow to the related instrument and equipment of these monitoring projects simultaneously.Then the task of the inspection of these monitoring projects (or calibration) span can be set to adopt same plenum system, and get identical time flow.So as long as wherein certain monitoring project has started inspection (or calibration) span task, other monitoring projects in fact also have been activated inspection (or calibration) span task simultaneously, and the data that these instrument and equipments provide just must be composed to the sign (PS (or CS)) of checking (or calibration) span well afoot.
Two, in automatic monitoring system, computing machine is very limited to the operation behavior of instrument and equipment, only needs kind order seldom---for example, send character string command, the order that receives character string and extract required content, data processing command etc.Allow computing machine with the common software of digital mode measurement and control instrument equipment in order to design, we utilize this engineering phenomenon at decision, and design compilation is a kind of to be specifically designed to and to write that imperatival language---we are defined as script.This language will realize telling software to do what, how do i by command statement, and the operational difference of the various job tasks of the various monitoring projects that cause because of institute's use instrument and equipment difference is embodied in the command statement, rather than in software program.As long as thereby the related command statement of this task be explained, be carried out to software can according to the task of monitoring project, just can be applicable to automatic monitor station point instrument and equipment existing and that update in the future---comprise the system support laboratory.
Script has been arranged, we can be website and system support laboratory software design: when needs are carried out certain task (for example reading the pollutant levels data) of certain monitoring project, earlier from record all command sets that can execute the task of this monitoring project---we are defined as the monitoring project script, find the serial command statement of this task operating pertinent instruments equipment and processing operating result; One of serial interpretation is carried out one.Determined also that thus quoting, remove, changing of website and system support Laboratory Instruments equipment for software, just shows as interpolation, deletion, the reorganization of the script of the monitoring project that uses these instrument and equipments.
Our design at present, the script that uses comprise following treaty rule and order: rule:
1, each bar order is all with " { " character begins, with " } " EOC.
2, all orders are all explained one by software according to the sequencing of writing one by one, carry out one.
3, order then is a character ": " with the character string beginning of command name code, is the character string of operation code then.The operation behavior of command code explanation order, operation code provides fill order parameters needed content.
4, the character string of operation code can comprise common variable (2 dimension group) MyData (i, j), i=1 to 100, j=1 to 100 and storehouse parameter L ibData (i), i=1 to 100.The numerical value of the storehouse parameter that order is used, assignment when order is write.The numerical value of common variable is by command execution process assignment.
5, common variable has only a following timestamp, then default acquiescence j=1.
6, ", HEX (n), " 16 carry system codes of expressing that can comprise usefulness in the operation code character string, wherein n is conventional 10 system numbers, is reduced to 16 system numbers in the operation code character string according to the numerical value of n during command execution.
7, in the command format explanation expression formula, the character content that Text (I) fills in for the user, the 10 system numerical value that n (I) and m (I) fill in for the user, Table (I) is a tab, all the other are order proper string and variable expression character; Wherein I is the integer of 0 to i, can defaultly be defaulted as 1.
Order:
(1), { Type:Text} is for explaining order.The order (perhaps command series) that prompting below will be carried out is programmed in the note content among the Text.
(2), { Err:Text} is that Data Identification is composed to order.If a last command execution is unsuccessful, the character among the Text is composed to data at that time as status indicator.
(3), { Delay:n} is the time-delay order.N is 10 system numbers.Just continue to carry out follow-up statement behind the time-delay n millisecond.
(4), { Send:Text} is for sending order.Send all characters among the Text.
(5), receive and extract contents command.This order has dual mode, adopts so-called " stamped " principle to intercept required content from character string.
Below explain mentioned order by instantiation:
Example one:
Command statement: Receive:; $so 2$$ppb$}{Infor:MyData (2) }
Received content: so2 36.9ppb
Intercepting result: MyData (2,1)=36.9
Example two:
Command statement: Receive:; $gflow actual$$target$$sccm$}{Correct:MyData (2,1), 1}
Received content: gflow actual 56.09 target 56.21sccm
Intercepting result: MyData (2,1)=56.09 MyData (2,2)=56.21
Example three:
Command statement:
{Receive：$；，HEX(13)，；1；；；$@@@@$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$$；$}{Infor：MyData(2)}
Received content:
@@@@10.2；w；632.1；；0.065；D；1.325；；1632.0；；43.56；CS；6.34；；12.2；；7.321；；452.1；；83.2；；24.5；PS；
The intercepting result:
MyData(2，1)＝10.2 MyData(2，2)＝w MyData(2，3)＝632.1
MyData(2，4)＝ MyData(2，5)＝0.065 MyData(2，6)＝D
MyData(2，7)＝1.325 MyData(2，8)＝ MyData(2，9)＝1632.0
MyData(2，10)＝ MyData(2，11)＝43.56 MyData(2，12)＝CS
MyData(2，13)＝6.34 MyData(2，14)＝ MyData(2，15)＝12.2
MyData(2，16)＝ MyData(2，17)＝7.321 MyData(2，18)＝
MyData(2，19)＝452.1 MyData(2，20)＝ MyData(2，21)＝83.2
MyData(2，22)＝ MyData(2，23)＝24.5 MyData(2，24)＝PS
For example:
Command statement: Receive:; , Hex (13); 1; $$14,8,1$$30,2,1$$}{Correct:MyData (2,1), A_F_4}
Received content :～2001D000D01242B500003DE147AE28F9AD
Intercepting result: MyData (2,1)=42B50000 MyData (2,2)=28
(6), { Infor:MyData (i) } is for preserving message command.The last time is ordered each section content that receives, extracts with Receive, be stored in the specify general variable, and automatically each section content composed in order to each variable in this array.
(7), { (i, j), Text} is the record data order to Correct:MyData.With the j section content that the last time receives, extracts with the Receive order, after formula calculates in Text, be stored in the specify general variable.Wherein:
Text is a numeral, then the numerical value of j section character string as numerical value and Text expression is multiplied each other.The default numerical value 1 that is defaulted as of Text.
Text is not, then keeps j section content former state.
Text is A_F_4, then j section content is reached as the asc code character string list of 4 byte single precision floating datums to be converted to 10 system numbers.
Text is H_F_4, then j section content is reached as the Hex code table of 4 byte single precision floating datums to be converted to 10 system numbers.

Though these order quantity seldom, is enough to let us and writes out used instrument and equipment kind, various monitoring project scripts that model is different.
Three, in any environmental contaminants automatic monitoring system, for any one monitoring project, Monitoring Data quality assurance and the desired job task of quality control standard standard are always limited, our analysis-by-synthesis modern observing and controlling engineering and the domestic and international prospective automatic monitoring standard standard of tool, design two task-set of any monitoring project of enough supports:
1, for monitoring project provides Monitoring Data, we are categorized as the task-set of " analytical instrument ", as follows:
Read Monitoring Data and check span C5
Read warning message and check zero point drift
Read diagnostic message and check the span drift
Calibration zero check span reappearance
The calibration span is checked multiple spot span 4 points
Check zero point:
Check precision:
Check span inspection multiple spot span 10 points
Check span 1 comparison standard source of the gas 2 tunnel
: comparison standard source of the gas 3 tunnel
: comparison standard source of the gas 4 tunnel
Check the 10 calibration times on date of span
Check that span A5 reads configuration information
Check span B5 switching range
2, for monitoring project provides inspection, calibration standard thing, we are categorized as the task-set of " calibration instrument ", and are as follows:
Reference material concentration diagnostic message
Warning message standby mode
A channel manual mode B passage automated manner 1
A channel manual mode 1:
： ：
: B passage automated manner 10

: H passage automated manner 0
: H passage automated manner 1
B path manual mode 10:
B path manual mode B5:
B passage automated manner 0 H passage automated manner 10
Above-mentioned task-set has been arranged, made design, the use of automatic monitoring system computer software, in fact progressive for breaking away from the oriented mission mode of concrete model instrument and equipment.The operation of software is exactly to carry out each monitoring project, takes place automatically according to sequential, or the man-machine interaction task of exciting---can be comprising in the above-mentioned task-set of task only certainly.
Such as the process of gathering the real-time Monitoring Data of pollutant, be programmed for according to the cycle of setting, each monitoring project is carried out " reading Monitoring Data " and " reading warning message " task, and add up, write down data and the sign obtained.
Again such as, check the span of instrument and equipment that certain monitoring project uses, be programmed for this monitoring project " inspection span " task of carrying out, and according to the flow process that sets in this " inspection span " task, make the task (for example " A channel automated manner 1 ") of the calibration instrument execution appointment of appointment, continue the time of appointment, carry out " standby mode " stopping criterion thing then and carry, the time of waiting for appointment again is to recover actual sample supply, task termination.Naturally data of this monitoring project are assigned to and check the ongoing sign of span (PS) during this.
Each bar task of enumerating out in above-mentioned task-set, existence is very interesting each other, and very useful relation.These relations are to use those things that is referred to as instrument and equipment at us, build automatic monitor station point and system support breadboard the time " with the life tool ",
These tasks be have behavior evolve level other.High level task can be explained, is decomposed into some minimums at last, can not divide the task of direct control instrument and equipment again.We are defined as first task task this minimum, not subdivisible, and for example, those need read, write the task of code to instrument and equipment that monitoring project uses.A last rank, be that those include the task that calibration instrument quasi-instrument equipment is operated simultaneously, task as inspection, the zero point of calibrating the used instrument and equipment of monitoring project, span and so on, they are except the task of Operations Analyst instrument class instrument and equipment, also comprised the task of operation calibration instrument class instrument and equipment transfer criteria thing, we are defined as simple task.Highest level, be those directly by simple task, even the first task queue task of forming, we are defined as combined task, for example, and comparison reference material concentration, check tasks such as multiple spot span, they are by the formation of checking that zero point and inspection (at different levels) span task conspire to create.
This behavior evolvement method is reminded us, as long as can allow the related instrument and equipment of each monitoring project carry out first task, utilize the evolutionary mechanism of task so, certainly can accomplish to come operating instrument equipment by computing machine fully, finish complicated task---and task in the script order write only just enough to first task.
Certainly, not all automatic monitor station point and system support are breadboard, and the monitoring project of each pollutant or context parameter all has an opportunity to use each the bar task in the above-mentioned task-set.This will see that the employed instrument and equipment of monitoring project is integrated.Present characteristics are to use the instrument and equipment that newly manufactures and designs can bear more relatively task---more help implementing high-caliber Monitoring Data quality assurance and quality control; The pollutant monitoring project need be born than the more task of context parameter project.Therefore.For each automatic monitor station point and system support laboratory, each monitoring project all can have a series of of oneself to execute the task, and we can execute the task these and be recorded in the monitoring project script.
In the monitoring project script, the record that each can be executed the task except comprising the order of writing with script, also must comprise various explanations and setting, with can be by the computer software programs correct execution.
We design the executed the task record form of use at present, comprise following segmented content:
1, type---acquiescence is filled in character A, represents that this is recorded as and can execute the task.
2, task---task names.
3, script---monitoring project script name.
4, standard---with the interface standard of instrument and equipment communication.
5, port---with the computer hardware of instrument and equipment communication.

12, continue, calibration value, recover---fill in the reference material service time, the reference material concentration value, Wait-to-Restore is to the authentic sample service time.
13, order---the command series of writing with script.
The script name of the monitoring project of 14, association---association when carrying out this task (data of associated project are assigned to the term of execution of this task and wait for sign).
The numerical value of 15, storehouse parameter---each storehouse parametric variable of setting when carrying out this task.
16, the task string that originating task---this mission requirements is carried out in proper order.
Annotate: task does not need the content of the segmentation that relates to should be empty (not fill substance).
Writing of the script logging that monitoring project can be executed the task, needing one can provide the special-purpose editing machine of filling in all segmented contents.We have designed the script-editor of one style such as accompanying drawing 8 for this reason.Wherein the major function district is described as follows:
1, classification---be used for selected project and belong to the analytical instrument class, or the calibration instrument class.
2, instrument---be used for listing, add, delete, selecting the project script of classification.
3, " task "---each bar task of list, selected this classification task being concentrated.
4, standard---. list, select computing machine communication standard (agreement).

17, button---edited result is saved as executed the task record in the script.But whether test current selected task correct execution.The current selected task " is appended " in the task queue of waiting for the software execution, or the like.
So far, as long as automatic monitor station point and system support laboratory computer software program are had the ability, when needs are carried out certain task of certain monitoring project, from associated script, find the record of this task, according to order in the task record and condition, pertinent instruments equipment is carried out observing and controlling then.So, we just are no longer necessary for the different computer software of the integrated design of different instrument and equipments, and it is integrated also not need the system centre managerial personnel to remove to be familiar with in the system omnifarious instrument and equipment.
Four, in automatic monitoring system, the task in the task-set that we design, frequency that is activated and reason are very different.Bear the characteristics of these tasks from automatic monitor station point and system support laboratory, they can be divided into real-time task, routine mission and regulation and control task.
Real-time task is that those computer program timing automatic are carried out the task of---whether do not comprehend other tasks carries out---.For a pollutant monitoring project, no matter be carrying out the authentic sample monitoring, what still in the inspection of carrying out various indexs, calibration, gather, write down all is about the data of concentration and Data Identification at that time.So resemble the task that " reading of data " and " reading warning message " and so on belongs to the data acquisition aspect, always be used as real-time task.
Routine mission is that those are guaranteed by the quality of data and quality control system requires regularly to carry out, with the task of the examination quality of data and maintenance levels.Routine mission can be passed through manager's computing machine, or mandate office computer, or site computer is formulated, be illustrated in figure 5 as the operation interface when checking, Figure 6 shows that the operation interface when carrying out the layout work of routine mission by site computer by the routine mission of authorizing office computer to carry out.This type of duty cycle is extremely strong, can be customized to a series of and concrete irrelevant cycle of calendar simply: every day, and every day, weekly, and every week, every month, every the moon, per season, every half a year, every year, or the like.Thereby we carried out a kind of out of traditional, with irrelevant routine mission mechanism of date.Its rule is as follows:
---every day task on Monday, three of single-revolution, five and carry out on Sun., two, four, six in two weeks.With on January 1st, 1970 be that single-revolution plays calculating.
---task was carried out on Monday weekly.
---carry out on Monday of single-revolution every all tasks.
---task was carried out at the 1st day every month in every month.
---every the moon task carried out in 1st at Dan Yuedi.
---per season task carried out the 1st day per season
---every season (half a year) task carried out in 1st at every single cropping
---annual task was carried out at annual the 1st day.
---task timeliness priority (from high to low) is: year, season, the moon, week, day; If there is one day more than a kind of routine mission to meet the condition of carrying out simultaneously, then only carry out the highest-ranking routine mission of timeliness.
This routine mission realizes as follows:
(1) uses script editor, logger task instruction, make site computer can call, explain, carry out these assignment instructions records;
(2) routine mission is set in site computer, regularly finishes the inspection of Monitoring Data quality assurance, quality control requirement, the observing and controlling operation of tester equipment performance automatically;
(3) site computer is regularly carried out above-mentioned routine mission, and the relevant data record that monitoring instrument equipment is obtained sends it back manager's computing machine.
The regulation and control task, be those by the monitoring system managerial personnel momentarily, carry out local startup of site computer (comprising the system support laboratory computer), perhaps authorizing office computer and manager's computer long distance remote control to start carrying out of task.This need be from instrument and equipment maintenance and repair, performance diagnogtics, the quality of data guarantees the effect audit with control, and work such as new equipment, new industrial research.
Five, in order can particularly authorizing on the office computer easily, to need, automatic monitor station point and system support laboratory to be carried out Remote, start the relevant task of carrying out according to system management manager.We utilize designed, have the automatic monitor station point computer software of oriented mission characteristic and technology, the method for consolidation system versatility, have set up a kind of uniqueness, very simple and direct website Remote flow process.
In manager's office computer software of our design, design has the user interface of " task Remote ", sees accompanying drawing 2---task Remote interface.Behind selected automatic monitor station point, monitoring project, task and method of calling (as " interpolation formation "), information enough allowing the site computer software program find appointed task and start according to method of calling from specify script is uploaded to data designated storehouse server.Utilize between itself and the controlled website by this server software program,, these information are transmitted down for the communication channel that the instantaneous monitoring data transmission is set up.In this process, can be by each nearest 10 minutes monitoring project transient data of this website on the user interface, the effect that observation mission is started.This Remote is realized as follows:
(1) uses script editor, logger task instruction, make site computer can call, explain, carry out these assignment instructions records;
(2) send assignment instructions to site computer by manager's computing machine or mandate office computer;
(3) site computer receives above-mentioned assignment instructions, and the record of writing with script according to assignment instructions, and the measurement and control signal of corresponding form is sent to relevant monitoring instrument equipment;
(4) the above-mentioned measurement and control signal of monitoring instrument device responds sends it back site computer with the relevant data of its acquisition;
(5) site computer sends it back manager's computing machine with above-mentioned data.
Six, for program and communication load,, need to guarantee the data of permanent recording, all, be pooled to manager's Computer Database server of appointment the most in time intactly from the automatic monitor station point to remedy mode automatically with minimum.We are according to the reliability testing result of network environment and database service end software, designed a kind of we be defined as the data transfer mode of " upwards backup ".The main body rule is as follows:
---automatic monitor station point and system support laboratory computer software, must guarantee only to send a Monitoring Data record to database server at every turn, and the time interval between each the transmission, must be more than or equal to 5 seconds.
---database server software needs permanent each bar Monitoring Data record of preserving to what receive, must send the original text of (repayment) record to the website that record is provided, as " receipt ".
---automatic monitor station point and system support laboratory computer software, must be to also not receiving database server " receipt ", need the permanent Monitoring Data record of preserving, carry out the dynamic priority queuing, guarantee between same twice transmission of record (reissuing) interval greater than or equal 5 minutes, and guarantee between twice transmission interval greater than or equal to send up-to-date needs and replenish the record that sends under 5 seconds the prerequisite.
Be illustrated in figure 7 as site computer and carry out data, the display interface when sign is gathered, site computer is gathered the data, the sign that obtain with it and is generated local database record, and upload these records to manager's computing machine according to backup rules upwards, manager's computing machine receives the data recording that sent by site computer and it is kept in the database server.Guarantee, control effect by the data recording and the analysis and distinguishing quality of data of authorizing office computer can browse in the inspection database server.Be illustrated in figure 3 as the display interface of authorizing office computer to check each station data reception condition, by authorizing the software program on the office computer data recording that receives can be depicted as the mathematics chart, demonstrate the situation of change of environmental monitoring data more intuitively, be illustrated in figure 4 as the display interface when authorizing office computer to carry out data check.
The solution of the above " upwards backup " is specially adapted to domestic network environment, and has reduced the treatment capacity of database server significantly.The systematic comparison approximate with domestic scale, integrality, the promptness of each website Monitoring Data record greatly improve in the database server of native system.Started to grind and built new approaches and technology path large-scale, general automatic monitoring system.
In sum, the present invention has realized a kind of multiple instrument and equipment, many special topics (air, water, pollution source etc.) and the universal environmental contaminants automatic monitoring system and monitoring method of (trans-regional) on a large scale of being applicable to, for realizing scientifically monitoring and solve problem of environmental pollution, provide comprehensive, complete, detailed Monitoring Data.
