Specifically, being equipped with the standard solution or diluted standard solution for having card according to parameter to be checked, advised according to calibrating
Journey directly transports ready standard solution or water sample, or intelligence prepares required standard solution or mark-on water sample.Such as: with
For the calibrating of COD online automatic monitor, need to carry out null offset, stability of display and the error of indication three
Test, therefore the calibration solution prepared in advance is respectively the Potassium Hydrogen Phthalate mark of 0mg/L, 50mg/L, 150mg/L, 500mg/L
Quasi- solution is as corresponding COD standard liquid.
S2, by standard solution or water sample according to program sequentially with volume transportation to specimen cup, in specimen cup 101
There are three inside setting liquid level sensor (301,302,303), high, medium and low three kinds of liquid levels, the sample for various concentration are respectively corresponded
Preparation demand, to obtain test fluid.
Wherein, liquid level sensor includes the first liquid level sensor 301, the second liquid level sensor 302 and third level sensing
Device 303, specifically, the first liquid level sensor 301 correspond to high liquid level, liquid level in the second liquid level sensor 302 correspondence, third liquid level
Sensor 303 corresponds to low liquid level, is used to measure the pressure of the liquid level of specimen cup 101, and static pressure is converted to electric signal, then pass through
Excess temperature compensation and linear amendment, are converted to standard electric signal, feed back to calibrating installation 10.
Specifically, Field Force installs the standard liquid of corresponding test item at 10 end of calibrating installation, by liquid outlet with to
The injection port connection for examining equipment 20, starts the program of corresponding verification parameters, and the specimen cup of calibrating installation 10 is (opposite with the 101 of Fig. 2
Answer) in test fluid be implanted sequentially standard liquid.
For example, for completing JJG1012 verification process, program successively injects 8 pure water (zero points into specimen cup
Calibration solution), the COD standard liquid of 3 50mg/L, the COD standard liquid of the COD standard liquid of 3 150mg/L and 24 500mg/L, and note every time
The COD standard liquid entered is 100 milliliters.
S3, test fluid is detected by equipment 20 (corresponding with the 20 of Fig. 2) to be checked, to obtain the measurement number of test fluid
According to.
Specifically, the injection port 201 of equipment 20 to be checked is connect with the liquid outlet 101c of calibrating installation 10.Wherein, to be checked to set
Standby 20 use METHOD FOR CONTINUOUS DETERMINATION modes, successively extract test fluid to the specimen cup 101 of calibrating installation 10, by equipment 20 to be checked to obtaining
The test fluid taken is measured one by one, obtains one group of measurement data.
The data transfer of test fluid to calibrating installation 10 is sent to by S4, equipment to be checked 20 by wireless network
Data interchange platform.Wherein, data interchange platform refers to that several application message methods by dispersion construction are integrated, and meter is passed through
The information exchange platform of calculation machine network struction, it makes several carry out the transmission and shared, raising of information/data using submethod
The utilization rate of information resources becomes the elementary object for carrying out informatization, guarantees to interconnect between distributed delays method, build
Vertical central database, completes the extraction of data, concentration, loads and show, construct unified data processing and exchange.
Specifically, before equipment 20 to be checked measures test fluid, equipment 20 to be checked and calibrating installation 10 are logical in advance
News connection, at the end of every group of measurement, measurement data is pushed to calibrating installation 10 by way of communication by equipment 20 to be checked, calibrating
Device 10 is retransmited to data interaction platform.
S5, mobile terminal APP can be directly viewable the measurement data of equipment 20 to be checked, and calculate phase automatically with corresponding vertification regulation

The calibrating reagent that the vertification regulation JJG1012 of oxygen demand (COD) online automatic monitor is related to be respectively 0mg/L, 50mg/L,
The COD standard solution of 150mg/L and 500mg/L.
Standard solution or water sample to be measured are suspended to corresponding reagent bottle position respectively by S12.
For example, in the corresponding monitoring instrument verification process of some parameters, calibrating installation 10 is equipped at least three reagents
Bottle, before calibrating, standard solution need to be suspended to corresponding reagent bottle position, needed before work connection calibrating installation 10 water outlet and
The injection port of equipment 20 to be checked.In addition, this calibrating/included bar-code label of calibrating installation institute band reagent, includes concentration and equipment
The information such as parameter setting, Field Force need to only scan body two dimensional code, and calibrating installation 10 can recognize and be arranged corresponding parameter,
Without parameter setting one by one manually, avoid manual operation improper or the data result of erroneous effects calibrating.
Specifically, in some embodiments, under normal circumstances, it is molten to be ready for examining and determine the standard that each step needs by step S1
Liquid is not necessarily to extemporaneous preparation, need to be by program by certain when needing water sample mark-on reclaims to test or the concentration point deficiency of S1 preparation
Volume ratio prepare in the specimen cup (corresponding in Fig. 2 101) needed for test fluid, set that there are three liquid levels to pass in specimen cup
Sensor (301,302 and 303) respectively corresponds high, medium and low three kinds of liquid levels, and the test solution for various concentration, different sampling volumes is matched
Demand processed.
S22, operation validation program, successively in specimen cup 101 inject or prepare corresponding concentration standard solution or to
Water sample is surveyed, the volume injected or prepared every time is identical, to obtain test fluid described in S3.
For example: for completing JJG1012 verification process, program successively injects 8 pure water, 3 into specimen cup 101
The COD standard liquid of the COD standard liquid of secondary 50mg/L, the COD standard liquid of 3 150mg/L and 24 500mg/L, 100 milliliters every time.
In some embodiments, equipment 20 (corresponding with the 20 of Fig. 2) to be checked is transmitted by data automatically by measurement data
Feed back to calibrating installation 10.
Calibrating installation 10 is retransmited to data interaction platform, and technical staff can consult equipment 20 to be checked by mobile terminal APP
Measurement data, can refer to corresponding calibrating according to calculating corresponding index value automatically, and whether automatic Evaluation respectively examines and determine project
It is qualified.
In full-automatic calibrating/calibration method using water quality monitoring of the invention, personnel can be left after program starting,
Calibrating is whole to be not necessarily to manual operation, greatly improves work efficiency, is detached from the dependence to examining and determine manually, can be effectively reduced fortune
Row cost.
