Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, a functional block diagram of a first embodiment of an automated water quality testing system according to the present invention is shown.
As shown in fig. 1, a first embodiment of the present invention proposes an automated water quality detection system, the system comprising:
the pretreatment module 10 is used for carrying out pretreatment on the water sample to be detected to obtain the water sample to be on-line;
specifically, referring to fig. 2, fig. 2 is a schematic diagram of a first refinement of a first embodiment of an automated water quality detection system according to the present invention, the pretreatment module comprising:
the filtering device 101 is used for automatically filtering the water sample to be detected;
when the turbidity of the water sample to be detected is high, and the subsequent detection can be influenced, filtering treatment is needed to remove impurities such as sediment, floaters and the like in the water sample. In the embodiment, an automatic filtering device is configured in the pretreatment module, and the automatic filtering is realized through the automatic filtering device, so that a clear water sample is obtained.
The centrifugal device 102 is used for automatically centrifuging the water sample to be detected according to a preset centrifugal rotating speed and a preset centrifugal time;
centrifugation is a technique in which a solution is rotated around an axis at a high speed, and some components are precipitated by centrifugal force, and some components remain in the supernatant. The separation effect is stronger than that of filtration, and the centrifugal device 102 according to the present embodiment may be an automatic centrifuge. A centrifugation program including balance test, centrifugation rotation speed, centrifugation time, etc. is set in advance according to the detection requirement, for example, a first centrifugation program is set to: the centrifugal speed is 500r/min, the centrifugal time is 1min, and the centrifugal operation is automatically started after the balance test is passed.
The solution preparation device 103 is used for diluting the water sample to be detected and/or preparing a standby detection reagent in the detection process.
The solution preparing device 103 comprises automatic solution preparing equipment such as a full-automatic standard solution preparing instrument, automatic reagent preparing equipment, a full-automatic standard solution preparing instrument and the like. The full-automatic preparation of the solution can greatly save manpower and improve the safety and accuracy of the solution preparation.
The dilution operation of the water sample to be detected needs to set the dilution factor in advance according to the requirement, then the solution preparation device measures the water sample to be detected and distilled water based on the dilution factor, and the diluted water sample to be detected is obtained after the vibration, stirring or shaking operation.
In other embodiments, if the detection of organic matters in water is required, the extraction, distillation and other operations may be performed during the pretreatment process. Based thereon, the pretreatment module 10 further comprises an extraction device and a distillation device. Specifically, the water sample to be detected is automatically extracted based on an automatic extractor, and the components to be detected are extracted from the water sample to be detected based on an organic solvent, so that a required organic phase is obtained. Distillation operations are performed based on fully automatic distillation apparatus to obtain the desired distillate.
In other embodiments, other pre-processing means may be added based on the item to be detected, such as weighing means, evaporating means, concentrating means, etc.
Furthermore, the preprocessing module further includes:
the numbering and tracing unit is used for numbering the water sample to be detected according to a preset rule to obtain a sample graphic code, and integrating the related information of the water sample to be detected into the sample graphic code for subsequent sample tracing based on the sample graphic code. The preset rules are set according to needs, such as sequential coding of water samples according to dates, coding of detection items based on sources, random coding and the like. The relevant information integrated into the sample image code may include test items, water sample sources, laboratory staff, dates, environmental data, and finally obtained test results. The sample graphic code may be a two-dimensional code, a bar code, a applet code, or the like. Therefore, when water sample tracing is needed, the relevant information of the water sample can be obtained only based on the corresponding sample graphic code.
The automatic sample injection module 20 is used for executing sample injection operation on the water sample to be on machine so as to enter a detection flow;
the automatic sample injection module can be a sample injection device configured by the automatic detection equipment, for example, the metal ions in water are detected based on ICP atomic emission spectrometry, and then a sample injection system of the ICP atomic emission spectrometry can be regarded as the automatic sample injection module.
The automatic sample injection module comprises a sample injector and a sample tray, wherein the sample injector is used for sending a water sample to be put on the machine to the detection system, and the sample tray is used for storing other water samples to be put on the machine. And:
the sample injection control unit is used for sending the water sample to be put on the machine in the sample tray to the automatic detection module through the sample injector based on a preset process. The sample injection control unit sucks a certain amount of water sample to be put on the machine according to a preset flow and program, and sends the water sample to be put on the machine to an automatic detection module, or the sample injection control unit places the water sample to be put on the machine to a detection position so as to detect the water sample to be detected.
In addition, the automatic sample feeding module further comprises a sample numbering unit, and the sample numbering unit is used for numbering the water sample to be put on machine according to a preset rule and a project to be detected to obtain a sample code, so that the corresponding detection result can be output based on the sample code. Typically, the sample is encoded as numbers, letters, or a combination of both.
It should be noted that, for some automatic detection devices that are not equipped with an automatic sample injection module, a full-automatic robot may be selected as the automatic sample injection module.
For example, the current pH automatic detector needs to be manually calibrated, and then the probe is manually placed into the water sample to be detected to obtain the pH value. Therefore, for the current pH automatic detector, a mechanical arm capable of automatically moving a probe and a distilled water automatic switching device capable of automatically cleaning the probe are provided, a sample tray for setting a pH value calibration standard liquid is used for storing the pH value calibration standard liquid, and a mechanical arm operation program, a distilled water automatic switching device program, a current pH value setting calibration program and a pH value automatic detection program are set so as to realize the full-automatic detection of the pH value without the operation of an experimenter.
The automatic detection module 30 is used for detecting the water sample to be on machine according to a preset flow, obtaining a detection result and transmitting the detection result to the management module;
currently, many automatic detection devices are equipped with an automatic detection module, so that a detection result can be automatically obtained, the labor intensity of an experimenter is greatly reduced, and the detection accuracy can be improved.
Since water quality detection generally requires detection of a plurality of detection items, different detection items require different devices to obtain corresponding detection results.
Specifically, referring to fig. 3, fig. 3 is a second detailed functional schematic diagram of the first embodiment of the automatic water quality detection system of the present invention, and as shown in fig. 3, the automatic detection module 30 includes:
