[0002] Traditional laboratories, especially in the petroleum and chemical testing fields, often use reagents that are flammable, explosive, toxic, or corrosive gases, water, or fluids. Detecting these substances presents several significant challenges, including personnel safety in contact with the reagents, low testing efficiency, and poor data reliability.

[0003] Manual pipetting and solution preparation rely heavily on operator experience, making them prone to volume discrepancies, resulting in poor repeatability of test results, frequent human errors, and difficulty in ensuring data accuracy. Paper-based records are prone to omissions or errors in recording key information such as reagent batch numbers, expiration dates, and usage quantities, failing to meet the requirements for traceability of experimental data. Safety hazards are prominent, with high compliance risks. Petroleum and chemical reagents are generally toxic and corrosive, and leaks and splashes are prone to occur during manual handling and preparation, leading to safety accidents such as poisoning and burns. Real-time monitoring of reagent inventory and expiration dates is impossible, posing a risk of penalties from regulatory authorities. Furthermore, manual operations make it difficult to achieve full lifecycle traceability of reagents. Differences in reagent preparation methods and reaction condition control among different operators lead to poor consistency in test results, failing to meet the chemical industry's requirements for standardized test data.

As another example, the auxiliary control system of this application can be applied to home appliances or office equipment. Such changes in application do not deviate from the basic principles of this application and should fall within the scope of protection of this application.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0025] Furthermore, in the description of this application, unless otherwise expressly specified and limited, the term "connected" should be interpreted broadly.

[0027] Figure 1 This is a schematic diagram of one embodiment of the reagent monitoring device of this application. Figure 2 This is a schematic diagram of one embodiment of the reagent pump set of this application. Figure 3 This is a schematic diagram of the structure of one embodiment of the multi-station reagent addition device of this application.

[0028] like Figure 1 As shown, in a first aspect, embodiments of this application provide a reagent monitoring device. The reagent monitoring device 1 includes a reagent bottle frame body 11, multiple pressure sensors 12, and a signal conversion module 13. The reagent bottle frame body 11 has bottle placement positions 111 of different sizes. A pressure sensor 12 is disposed at the bottom of each bottle placement position 111, and a reagent bottle 14 of the corresponding size is placed on top of the pressure sensor 12. The signal conversion module 13 is communicatively connected to the pressure sensor 12 and is used to receive the electrical signal transmitted from the pressure sensor 12 and convert it into the reagent remaining amount of the corresponding reagent bottle 14.

[0029] Specifically, the reagent bottle frame body 11 is a frame structure with multiple bottle placement positions 111 of different sizes spaced out on it. Each bottle placement position 111 is the location or area for placing the reagent bottle. A pressure sensor 12 is preferably placed at the center of the bottom of each bottle placement position 111. This pressure sensor 12 is directly connected to the reagent bottle 14 above it. The weight of the reagent inside the bottle is completely transmitted to the pressure sensor 12, and changes in the remaining reagent volume are directly reflected in changes in pressure. Because the pressure sensor 12 is in close contact with the bottom of the reagent bottle 14, it detects the total weight pressure of the reagent bottle 14 (including the reagent) in real time. In the initial state, the pressure sensor 12 records the pressure value when the bottle is full (the upper pressure limit corresponding to 100% remaining volume) and the pressure value when the bottle is empty (the lower pressure limit corresponding to 0% remaining volume). When reagent is taken through the delivery pipeline, the total amount of reagent decreases, and the pressure on the pressure sensor 12 decreases accordingly, converting the real-time pressure change into a corresponding weak electrical signal. The signal conversion module 13 amplifies, filters, and reduces noise from the received weak electrical signal to obtain an accurate electrical signal. The system performs analog-to-digital conversion on the electrical signal, converting it into a digital signal for subsequent data calculations. Based on preset upper pressure limits for full bottles and lower pressure limits for empty bottles, it calculates the remaining reagent level corresponding to the real-time pressure using existing conventional algorithms, converting it into a percentage value. For example, if the real-time pressure is 60% of the full pressure, the displayed remaining level is 60%.

[0030] Preferably, the reagent bottle is a brown reagent-specific bottle. Using a brown reagent-specific bottle utilizes its light-shielding properties to protect the reagent, which is especially suitable for photosensitive reagents and prevents reagent deterioration.

[0031] In a preferred embodiment of this application, the cap of the reagent bottle 14 is provided with a single-exit filter valve and an inlet / outlet pipe interface, wherein the single-exit filter valve is used to balance the internal and external air pressure of the reagent bottle 14; and the inlet / outlet pipe interface is used for reagent dispensing and replenishment.

[0032] Specifically, the cap of reagent bottle 14 can integrate a single-exhale filter valve. This single-exhale filter valve allows only exhaled gas and prevents inhalation. It balances the internal and external air pressure of reagent bottle 14, preventing reagent evaporation or the intrusion of external impurities. The inlet and outlet pipe interfaces are used for quantitative dispensing or replenishment of reagents, ensuring the sealing and controllability of the reagent dispensing process.

[0033] In a preferred embodiment of this application, the reagent bottle 14 includes 100ml reagent bottles 14, 1L reagent bottles 14 and 2L reagent bottles 14 in decreasing quantities, and the quantity of the 100ml reagent bottles 14, 1L reagent bottles 14 and 2L reagent bottles 14 is sufficient for one week of use.

[0034] Specifically, the number of reagent bottles is set according to their capacity. In a preferred embodiment, the number of 100ml reagent bottles 14 is set to 8, the number of 1L reagent bottles 14 is set to 6, and the number of 2L reagent bottles 14 is set to 2. The quantity of reagent bottles of different specifications is sufficient to meet at least one week's usage requirements based on the amount of testing reagents needed.

[0035] In a preferred embodiment of this application, the reagent monitoring device further includes a display and alarm device, which is communicatively connected to the signal conversion module 13 and is used to display the remaining reagent level and trigger a low liquid level alarm when the level is below a preset alarm value.

[0036] Specifically, the signal conversion module 13 transmits the percentage value of the remaining reagent to the display and alarm device in real time. The display and alarm device stores an alarm preset value, which can be, for example, 10%. When the level falls below this value, a low liquid level alarm is immediately triggered to prevent empty filling due to insufficient remaining liquid and to avoid affecting the efficiency of liquid delivery.

[0037] The reagent monitoring device 1, as described above, can meet the quantitative storage requirements of reagents for experiments. It uses a pressure sensor 12 and a signal conversion module 13 to monitor the remaining liquid level in reagent bottles 14 of different sizes in real time. Low liquid level alarms are provided via display and alarm devices for convenient and timely replenishment.

[0038] like Figure 2 As shown, in a second aspect, this application provides a reagent-specific pump set 2, which is used in conjunction with the aforementioned reagent monitoring device 1. The reagent-specific pump set 2 includes a pump set frame body 21, a pump set 22, and a solenoid valve group 23. The pump set 22 is disposed on the pump set frame body 21. The solenoid valve group 23 is disposed between the total output end of the pump set 22 and the delivery pipeline of the reagent bottle 14 in the reagent monitoring device 1, and is used to connect the pump to be started in the pump set 22 with the designated delivery pipeline.

[0039] Specifically, the reagent-specific pump set 2 allows for on-demand pump selection, solenoid valve group switching, and precise adaptation to petrochemical testing scenarios. Through the functional division of different pump types and the pipeline scheduling of the solenoid valve group 23, it meets the diverse reagent transfer needs of 20 process pipelines. The pump set frame body 21 is an L-shaped frame, including a horizontal plate and a vertical plate connected to each other. Pump sets 2 are evenly distributed on the horizontal and vertical plates. The solenoid valve group 23 is located on the upper side of the pump set 22. The coordinated operation of the pump set 22 and the solenoid valve group 23 enables the connection and disconnection of various reagent bottles 14 from the delivery pipelines in the reagent monitoring device 1.

[0040] In a preferred embodiment of this application, the pump assembly 22 includes: 7 syringe pumps 221, 2 multi-channel peristaltic pumps 222, 1 diaphragm pump 223, and 1 single-channel diaphragm pump 224 to meet the needs of at least 20 delivery lines. Specifically: the syringe pumps 221 are used for the standard solution preparation stage of precise quantitative reagent delivery; the multi-channel peristaltic pumps 222 are used for the sample pretreatment stage of reagent delivery with corrosion and contamination prevention; the diaphragm pumps 223 and 224 are used for the waste liquid treatment stage of reagent delivery under high pressure and complex operating conditions. The diaphragm pumps 223 are suitable for multi-line requirements, and the single-channel diaphragm pumps 224 are suitable for single-line requirements.

[0041] Specifically, the selection of the syringe pump 221, multi-channel peristaltic pump 222, diaphragm pump 223, and single-channel diaphragm pump 224 depends on four key factors: reagent characteristics, flow accuracy, pressure requirements, and contamination control. It is especially important to consider common scenarios in petroleum and chemical testing involving corrosive, toxic, and high-purity reagents (such as standard solution preparation, sample pretreatment, and waste liquid transfer). Among these, the syringe pump 221 possesses extremely high flow accuracy and repeatability, enabling precise delivery at the microliter level. Therefore, the syringe pump 221 is suitable for standard solution preparation and precise addition of trace reagents (such as calibration solutions and standard dilutions). The multi-channel peristaltic pump 222 delivers reagents by squeezing the tubing; the reagent only contacts the tubing and does not enter the pump body, fundamentally avoiding reagent contamination and pump corrosion. It is perfectly suited for reagents such as strong acids, strong alkalis, and high-purity solvents in petroleum and chemical testing. The multi-channel design allows for the simultaneous delivery of the same or different reagents to multiple pipelines, improving efficiency. Therefore, this multi-channel peristaltic pump 222 is suitable for corrosion-resistant and contamination-free batch transfers. Diaphragm pump 223 and single-channel diaphragm pump 224 achieve fluid transport through the reciprocating motion of the diaphragm, possessing advantages such as high head, high pressure, and particle resistance, and can withstand waste liquid containing impurities in petrochemical testing. Therefore, diaphragm pump 223 and single-channel diaphragm pump 224 are suitable for the suction and discharge of waste liquid (containing a small amount of particles and high viscosity), reagent transport under high pressure conditions, and reagent transfer over long-distance pipelines. The only difference between diaphragm pump 223 and single-channel diaphragm pump 224 is whether it is suitable for a single pipeline or multiple pipelines. Solenoid valve assembly 23 enables flexible switching of at least 20 pipelines, specifically designed for single reagents with multiple demand points and multiple pumps sharing pipelines. The total output end of pump assembly 22 is connected to the input end of solenoid valve assembly 23, and the 20 output ends of solenoid valve assembly 23 correspond to 20 delivery pipelines. By controlling the on / off state of the solenoid valves, the output of any pump can be directed to any one or multiple delivery pipelines.

[0042] In a preferred embodiment of this application, the reagent pump set 2 further includes a cleaning module. The solenoid valve set 23 is connected to the cleaning module and is used to clean the corresponding delivery pipeline after each reagent replacement to avoid reagent residue.

[0043] Specifically, after each reagent or pipeline change, the solenoid valve assembly 23, in conjunction with the cleaning module, flushes the delivery pipeline to prevent residual reagents from affecting the next batch of tests. For corrosive and toxic reagents used in petrochemical testing, the solenoid valve assembly 23 can be configured with a pipeline cleaning / draining function to automatically clean residual reagents in the pipeline when switching between different reagent delivery pipelines, thus preventing cross-contamination.

[0044] like Figure 3 As shown, in a third aspect, this application provides a multi-station reagent dispensing device 3, which cooperates with the aforementioned reagent monitoring device 1 and the aforementioned reagent-specific pump set 2. The multi-station reagent dispensing device 3 includes a linear module 31, a reagent support 32, multiple reagent needles 33, a sample bottle fixture 34, and a colorimetric tube fixture 35. The reagent support 32 is disposed on one side of the linear module 31, and a row of needle positions is arranged on the reagent support 32. Each reagent needle 33 is placed in a corresponding needle position. The sample bottle fixture 34 is disposed on the other side of the linear module 31 and is used to place multiple sample bottles. The colorimetric tube fixture 35 is located on one side of the sample bottle fixture 34 and is used to place multiple colorimetric tubes. The linear module 31 drives the sample bottle fixture 34 and the colorimetric tube fixture 35 to reciprocate, so that each sample bottle or colorimetric tube can be aligned with any reagent needle 33 for liquid dispensing. Each reagent needle 33 is connected to a delivery pipeline.

[0045] Specifically, the multi-station reagent dispensing device 3 can achieve automated station flow, dedicated pipeline for pollution prevention and liquid level sensing for precision control. It first achieves precise sample dispensing through the linkage of its own component linear module 31, reagent holder 32, multiple reagent needles 33, sample bottle fixture 34 and colorimetric tube fixture 35, and then forms a closed loop with the reagent-specific pump group 1 and reagent monitoring device 2, adapting to the full-process needs of laboratory batch testing.

[0046] The sample vial fixture 34 and colorimetric tube fixture 35 correspond to two types of sample-addition containers, respectively. They have clearly defined roles and work together to adapt to different testing scenarios, cooperating to complete batch sample addition operations. The sample vial is mainly used to hold liquid samples and perform basic pretreatment such as multi-reagent mixing reactions; the colorimetric tube is designed for testing scenarios such as spectral analysis, with a fixed volume to ensure precise matching of reagent addition and sample ratio, guaranteeing the accuracy of subsequent colorimetric detection. The reagent holder 32 is equipped with a row of reagent needles 33, each corresponding to a different delivery line, preventing cross-contamination between different reagents. Upon receiving a command, the linear module 31 moves the sample vial in the sample vial fixture 34 or the colorimetric tube in the colorimetric tube fixture 35 to the designated reagent needle 33 for liquid addition. After completion, the linear module 31 carries it back to its initial position or transfers it to the next designated position for subsequent liquid addition, thus achieving continuous batch liquid addition.

[0047] The reagent monitoring device 2, consisting of seven syringe pumps 221, two multi-channel peristaltic pumps 222, one diaphragm pump 223, and one single-channel diaphragm pump 224, provides precise power support for the multi-station reagent dispensing device 3, and works in conjunction with the solenoid valve assembly 23 to achieve compatible switching between pipelines and pump types. The reagent bottle 14, pressure sensor 12, and signal conversion module 13 of the reagent monitoring device 1 provide reagent balance monitoring and protection for the liquid dispensing process, enabling visual monitoring of the balance and low-level warnings.

[0048] In a preferred embodiment of this application, the multi-station reagent dispensing device 3 further includes a liquid level sensor 36, which is installed at the end of the delivery pipeline and is used to monitor air bubbles and backflow in the delivery pipeline.

[0049] Specifically, the level sensor 36 simultaneously calibrates the sensor and control module, setting the working thresholds for no air bubbles and no backflow, as well as the liquid addition accuracy parameters. This prevents air bubbles and backflow in the delivery pipeline from affecting accuracy, enabling precise and continuous reagent addition.

[0050] In a preferred embodiment of this application, the sample bottle fixture 34 and the colorimetric tube fixture 35 are further provided with limiting structures to prevent the sample bottle and colorimetric tube from shifting or being inverted during sample transfer and addition.

[0051] Specifically, the sample bottle fixture 34 fixes the sample bottle with a limiting structure, and the colorimetric tube fixture 35 fixes the colorimetric tube with a limiting structure to prevent it from shifting or being inverted during flow and liquid addition.
