[0041] The following is a detailed description of each module of the intelligent digestion detection system:

[0042] The sample placement module can be provided with a number of placement areas, which are respectively used to classify and place detection devices, standardize management, and reduce the calculation data of the processing module 3; it can also directly place the detection devices containing the samples to be tested, and each detection device has a The corresponding identification piece, which contains the relevant information data of the sample to be tested, is transmitted to the processing module 3 through the monitoring module 2 for identification. The identification part is a kind of barcode, two-dimensional code and electronic label. Firstly, the sample to be detected is placed in the detection device, and the sample to be detected will also be put back here after the relevant digestion detection is completed. Due to the existence of the monitoring module 2 and the identification piece, the processing module 3 can always know the relevant information of the detection device with the sample to be detected placed at any position in the sample placement module. Therefore, the sample placement module can directly place dozens or hundreds of detection devices.

[0043]The monitoring module 2 may include several cameras, and each camera is connected to the processing module 3 for acquiring first image information and transmitting the first image information to the processing module 3 . The camera can be separately set on the sample placing module, the digestion module 4 , the reagent adding module 5 , the detection module 6 and the transfer module 7 to monitor the working status of these modules. For example, by setting a camera on the sample placement module, images in the sample placement module to be tested can be directly taken, thereby monitoring the condition of each sample to be tested. For another example, if a camera is installed on the digestion module 4 , the digestion time can be determined directly according to the time when the sample to be tested is photographed in the digestion module 4 . In other embodiments, a timing unit may be set in the digestion module 4, and the digestion time is calculated by the timing unit.

[0044] The transfer module 7 includes a multi-axis manipulator, a rotating table, a manipulator, a transfer processing unit, and a camera; one end of the multi-axis manipulator is rotatably fixed on the rotating table at 360°, and the other end is provided with a manipulator for grabbing the detection device; the transfer processing The unit is connected to the processing module 3 for controlling the operation of the multi-axis mechanical arm, the rotary table and the manipulator; the camera is arranged on the other end of the multi-axis mechanical arm and connected to the processing module 3 for real-time shooting of the second image information, and the second The image information is transmitted to the processing module 3 . The transfer module 7 can grab the detection device at any position, and can also move the detection device to any desired position.

[0045] The digestion module 4 is provided with at least two digestion chambers, and when each digestion chamber performs digestion work, it is all timed separately; for example, a timer is set outside each digestion chamber to calculate the digestion time of the sample to be detected in the corresponding digestion chamber; The chambers can carry out the digestion work at the same time without affecting each other. Realize multi-bit simultaneous digestion. The digestion module 4 can be a microwave digestion instrument and/or an electrothermal digestion instrument.

[0046] The reagent addition module 5 includes several adding mechanisms, each adding mechanism includes a solenoid valve, an output pump, an adding head and a delivery pipe; one end of the delivery pipe is connected to the output pump, and the other end is connected to the adding head; the solenoid valve is arranged between the delivery pipe and the adding head , used to control on-off. The output pump here can be a kind of peristaltic pump, syringe pump and plunger pump.

[0047] The detection module 6 is one or more of a titration detection module, a spectral detection module, and a chromatographic detection module. It should be noted that when the detection module 6 is a titration detection module, including a color judgment sensor, the sample to be detected after digestion can be directly detected by the reagent addition module 5 under the control of the mobile module, and the color judgment sensor and processing Module 3 is combined with the color method to complete the detection. It should be noted that the color judging sensor can be replaced by a potential judging device, or can exist at the same time. The spectral detection module includes a stable light source and a photoelectric sensor. The photoelectric sensor follows Lambert-Beer's law and consists of a stable variable single-wavelength light source, a fixed optical path, and a high-sensitivity photoelectric sensor. The chromatographic detection module can use a liquid chromatograph, a gas chromatograph or an ion chromatograph.

The material that the sealing cover adopts is glass or plexiglass. It not only reduces environmental pollution, but also prevents the operator from accidentally injuring the operator during operation. The exhaust module includes an exhaust gas treatment unit, which is used to process various gases generated during digestion, discharge non-polluting gases, and reduce environmental pollution. The treatment method can be absorbed by absorption liquid, etc.

[0049] The third embodiment of the present invention also provides an intelligent digestion detection system that also includes a cloud server 8; the cloud server 8 is connected to the processing module 3 for storing detection data and establishing a comparison database. The cloud server 8 can be connected with the mobile terminal to realize remote viewing of the test results for query, and it can also be scheduled to start up in advance through mobile phones or computers. For example, the digestion module 4 can be heated in advance, and the self-inspection can be completed in advance. , the instrument has entered the stage of preparation.

[0050] The fourth embodiment of the present invention also provides an intelligent digestion detection system that also includes a cleaning module 9 for cleaning the detection device; the cleaning module 9 includes a waste liquid pool and a spray device with high-pressure water, the spray device and the processing module 3 connections. The detection device containing the sample to be detected is rinsed by the high-pressure water of the spraying device, and an acidic or alkaline liquid can be added to transfer the detection device to the reagent adding module 5 through the transfer module 7 to make the cleaning effect better. Because during manual cleaning, the cleaning personnel often open the water tap and close the water tap after cleaning, so the water consumption is very large. When the cleaning module 9 is automatically cleaned, the cleaning water will be provided as required under the control of the processing module 3, so the water consumption is greatly reduced, which is more environmentally friendly and reduces the impact of toxic and harmful reagents on operators.
