[0002] Water quality monitoring systems typically require long-term continuous operation, providing real-time monitoring of water quality indicators such as pH, chemical oxygen demand (COD), ammonia nitrogen, and heavy metal ions. This type of monitoring relies heavily on a variety of chemical reagents (such as colorants, buffers, and oxidants), whose types, concentrations, and expiration dates require strict management. The need for frequent reagent replacement, especially in remote areas, creates extremely high maintenance costs and stringent operational precision requirements, with any errors potentially impacting test results. Existing technologies based on manual identification and operation are inefficient and prone to error. While traditional automated control technologies can reduce the labor burden, they often lack flexibility and intelligent recognition capabilities, making them prone to reagent type confusion and misaligned cannula placement. Furthermore, the lack of reagent identity binding and full-process automated management makes it difficult to accurately monitor reagent expiration dates and usage records, leading to risks such as misuse of expired reagents and difficulty in data traceability.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0019] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. The described embodiments should not be considered as limiting the present application. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0022] Water quality monitoring systems typically require long-term continuous operation, providing real-time monitoring of indicators such as pH, chemical oxygen demand (COD), ammonia nitrogen, and heavy metal ions. These monitoring processes rely heavily on a variety of chemical reagents (such as colorants, buffers, and oxidants), with strict requirements for reagent type, concentration, and shelf life. Frequent reagent replacement, especially in remote areas, results in extremely high maintenance costs and stringent operational precision requirements, meaning any errors can directly impact test results.

[0023] Traditional water quality monitoring stations rely primarily on manual labor to complete tasks such as reagent insertion and removal and information verification. This method is not only inefficient but also poses safety risks, such as the risk of contact with corrosive reagents. Furthermore, manual identification can easily lead to reagent confusion or misplacement of the cannula, affecting the accuracy of test results. Furthermore, the lack of effective data recording makes full traceability difficult, hindering the development of unmanned monitoring stations.

[0024] Patent publication number CN118634697A discloses an automatic reagent replacement device for a monitoring station. The main idea is to store concentrated solvent in an elastic bellows and place mixed water in a reagent bottle. When the target solvent is needed, the up and down movement of the lifting platform is used to promote rapid mixing of the concentrated solvent and the mixed water.

[0025] The patent emphasizes the use of a robotic arm or conveyor belt to grasp, move, and position reagents, but does not include reagent identification and data linkage. This means it cannot automatically match reagent type to the test task, and intubation operations may rely on preset programs rather than dynamic adjustments. This design is inflexible in the complex and changing real-world operating environment and is prone to errors.

[0026] The patent with publication number CN118365142A discloses an automated reagent storage method, device and system. By fine-grained division of the internal space of the reagent storage device and monitoring the temperature data of each node, a temperature correlation network and a temperature risk map are constructed to identify potential abnormal areas. The reagent kits in these areas are inspected in detail, thereby accurately finding the reagent kits that do not meet the standards and visually marking them for timely processing. This technology uses RFID or barcodes to manage the storage location of reagents, which optimizes inventory efficiency, but fails to cover the intubation operation after the reagents are taken. Although it can effectively manage the storage of reagents, there are still breakpoints in the entire reagent management process, and the entire process cannot be fully automated. This limits its comprehensiveness and flexibility in practical applications.

[0027] Therefore, the main drawback of existing related technologies is that they are prone to significant human interference, including confusion of reagent types, deviation in intubation position, and the lack of reagent identity binding and full-process automated management mechanisms. This makes it difficult to accurately monitor the validity period and usage records of reagents, and can easily lead to risks such as misuse of expired reagents and difficulty in data traceability. At the same time, manual operations are inefficient, have high error rates, and high operation and maintenance costs, making them unsuitable for the efficient management needs of unmanned monitoring stations and smart environmental protection platforms.

[0028] In response to the problems existing in related technologies, the embodiments of the present application provide an automated reagent management method and device, which adopts the collaborative design of label recognition technology, mechanical positioning mechanism and pinhole tube insertion mechanism to realize the full automation from reagent reading and identification, positioning and transportation to pinhole tube insertion, and can be linked with the detection equipment. This method not only ensures the accurate management of reagent type, concentration, expiration date and applicable detection items, but also ensures the correctness and safety of use by automatically verifying label information. At the same time, it records detailed reagent usage data and synchronizes it to the cloud platform, thereby significantly improving monitoring efficiency and data accuracy, effectively reducing the need for manual intervention, and providing a more scientific and standardized solution for water quality monitoring. It is suitable for scenarios such as water quality monitoring stations that require frequent replacement of reagents.

[0029] First, the automated reagent management method provided in the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0030] Reference Figure 1The implementation process of the automated reagent management method provided in the embodiment of the present application includes but is not limited to the following steps.

[0031] Step 101: Scan and obtain label information on a reagent bottle.

[0032] The label information includes the reagent type, concentration, expiration date, and applicable test items corresponding to the reagent in the reagent bottle. The label on the reagent bottle can be in the form of a QR code or barcode.

[0033] In step 101, scanning and obtaining the label information on the reagent bottle is the starting point of the entire automated reagent management method. The encrypted label on the reagent bottle is identified and read by a high-resolution camera. The label contains key information about the reagent in the reagent bottle, including but not limited to the reagent type, concentration, expiration date and applicable test items. The significance of this step is to ensure that the identity of each bottle of reagent can be quickly and accurately confirmed, providing basic data support for subsequent operations. This label-based information entry method not only improves work efficiency, but also effectively reduces the errors that may be caused by manual input, ensuring the accuracy and reliability of the data.

[0034] Step 102 , verifying the validity of the label information. If the label information is valid, the robot arm is controlled to classify and store the reagent bottles into designated partitions. Otherwise, an alarm is triggered and the robot arm is controlled to transport the reagent bottles to the isolation processing area.

[0035] In step 102, after obtaining the label information, it is validated to determine whether it meets preset standards. If the label information is valid (e.g., not expired, correctly formatted, etc.), the robotic arm is controlled to sort and store the reagent bottles in designated partitions. If the information is invalid, an alarm is triggered and the robotic arm is controlled to transport the bottles to an isolated processing area. This process is crucial because it prevents expired or label-damaged reagents from entering the normal workflow, thereby avoiding biased test results or other potential risks due to improper use. Furthermore, promptly isolating problematic reagents helps maintain the cleanliness and efficiency of the inventory management system, ensuring that all available reagents are in optimal condition.

[0036] Step 103 , according to the label information and the instruction of the detection task, the robot arm is controlled to call the target reagent bottle that matches the detection task, and move it to the insertion and removal station for fixation.

[0037] In step 103, when a specific detection task instruction is received, the system will match the target reagent bottle that is most suitable for this detection task based on the label information, and control the robotic arm to move it from the storage area to the insertion and removal station for fixation. This step ensures that the reagents used for each test are the most appropriate, that is, they meet the specific requirements of the current test project. In this way, not only can the accuracy of the test be improved, but also the existing resources can be maximized and waste can be reduced. At the same time, this precise matching mechanism also supports the operational requirements of unmanned monitoring stations, making the entire process more intelligent and efficient.

[0038] Step 104 , controlling the pinhole tube to perform an insertion and extraction operation on the target reagent bottle on the insertion and extraction station, completing the extraction of the reagent in the target reagent bottle, recording the reagent extraction data and synchronizing it to the cloud platform.

[0039] In step 104, the control system guides the pinhole tube to perform the insertion and extraction operation on the target reagent bottle located on the insertion and extraction station to complete the use of the reagent. During this process, the system records detailed reagent extraction data, such as the amount used, time, etc., and synchronizes it to the cloud platform for subsequent query and analysis. This step not only achieves a high degree of automation in the reagent extraction process, reduces the possibility of manual intervention and the errors it brings, but also provides a solid foundation for data tracing. By real-time monitoring and recording each operation, the authenticity and integrity of the water quality monitoring data can be effectively guaranteed, further improving the scientific nature and standardization of the overall monitoring work.

[0040] In some embodiments of the present application, path planning instructions and obstacle avoidance instructions are generated through artificial intelligence algorithms to control the robotic arm to implement path planning and obstacle avoidance, so as to achieve classified storage and calling of reagent bottles.

[0041] In some embodiments of the present application, the artificial intelligence algorithm includes a SLAM algorithm.

[0042] The main principle of the SLAM (Simultaneous Localization and Mapping) algorithm is to construct a map of the environment in real time using sensor data, while simultaneously determining the position of the robot or device within that environment. It utilizes information from multiple sensors, such as lidar and cameras, combined with probabilistic algorithms and optimization techniques, to accurately estimate its own posture and map the structure of its surroundings. In the application of automated reagent management, the SLAM algorithm is crucial in enabling the robotic arm to dynamically perceive its workspace, generate efficient and safe path planning, and implement obstacle avoidance, thereby ensuring that the robotic arm can accurately classify, store, and retrieve reagent bottles, thereby improving the flexibility, reliability, and efficiency of the entire system. This technology not only reduces the need for human intervention but also improves the safety and accuracy of operations, making it particularly suitable for complex and changing working environments.

[0043] In some embodiments of the present application, the process of generating path planning instructions and obstacle avoidance instructions through the SLAM algorithm and controlling the robotic arm to achieve path planning and obstacle avoidance includes but is not limited to the following steps.

[0044] First, SLAM algorithms are used for environmental perception and mapping. In this initial step, the system uses SLAM algorithms to fully perceive the robot's working environment and create a detailed digital map. This step enables the system to accurately understand the surrounding spatial layout, including storage partitions, work surfaces, and the location of any possible obstacles. This precise environmental model provides the foundational data for subsequent path planning, ensuring the robot can move safely and efficiently in complex environments.

[0045] Next, based on the map information generated by the SLAM algorithm, the system further calculates the optimal path from the current position to the target location and generates corresponding path planning instructions. The core value of this step lies in optimizing the robot's movement path, which not only improves operational efficiency but also reduces unnecessary energy consumption. Furthermore, proper path planning prevents collisions between the robot and other equipment or obstacles, ensuring safe and smooth operation.

[0046] Furthermore, as the robotic arm performs its tasks, it continuously monitors dynamic changes in its surroundings and instantly adjusts its path as needed to avoid new obstacles. Through the real-time feedback provided by the SLAM algorithm, the system can quickly generate obstacle avoidance instructions, guiding the robotic arm to take the most appropriate evasive action. This step is important because it enhances the system's flexibility and adaptability, allowing the robotic arm to successfully complete tasks, such as sorting and storing or retrieving reagent bottles, even in a constantly changing working environment, without interruption or failure due to unexpected obstacles.

[0047] Finally, using the path planning and obstacle avoidance commands generated in the above steps, the control system precisely controls the robotic arm to complete the tasks of sorting, storing, and retrieving reagent bottles. Key to this process is the robotic arm's ability to automatically and accurately place specific reagent bottles in designated locations or select the target reagent bottle that meets testing requirements from a variety of storage units, based on pre-set logic and received commands. This approach effectively improves work efficiency and accuracy while reducing the need for human intervention, providing strong technical support for automated laboratory management.

[0048] In some embodiments of the present application, in step 102, the validity of the label information is verified. If the label information is valid, the robotic arm is controlled to classify and store the reagent bottles in designated partitions. Otherwise, an alarm is triggered and the robotic arm is controlled to transport them to the isolation processing area. The implementation process includes but is not limited to the following steps.

[0049] Step 201: Scan and obtain the label information of the reagent bottle and perform verification.

[0050] In step 201, a high-precision scanner first captures the label information on the reagent bottle. This label contains key information about the reagent, such as type, concentration, expiration date, and applicable test items. Immediately after acquiring this information, a preliminary verification is performed on this data to confirm its completeness and accuracy. This process is crucial for ensuring the correctness of subsequent operations, as it identifies and eliminates reagent bottles with damaged or incomplete labels, preventing operational errors or biased test results due to errors in the underlying data.

[0051] Step 202: If the label information meets the validity condition, the robot arm is controlled to move the reagent bottle to the corresponding classification storage partition according to the reagent type in the label information.

[0052] Among them, the validity conditions include compliance verification of reagent validity period, label form integrity detection, and data coding standardization verification.

[0053] In step 202, when the label information meets all the set validity conditions, including reagent validity period compliance verification, label form integrity detection and data coding standardization verification, the system guides the robotic arm to accurately transfer the reagent bottle to the corresponding classified storage partition based on the reagent type in the label information. The significance of this step is to achieve efficient and orderly inventory management, so that each type of reagent can be properly stored in the most suitable location for subsequent rapid call. This precise classification and storage method based on automation technology not only improves work efficiency, but also reduces the confusion and errors that may be caused by manual classification, ensuring the professionalism and reliability of the entire process.

[0054] Step 203: If any validity condition is not met, an alarm is triggered, and the robotic arm is controlled to move the reagent bottle to the isolation processing area, and an abnormal operation log is generated.

[0055] In step 203, if any validity condition is found to be unmet during the label information verification process (for example, the reagent is expired, the label is damaged, or the data encoding is abnormal), the system will immediately trigger an alarm to alert the operator to the current abnormal situation. At the same time, the robot arm will be instructed to move the problematic reagent bottle to a dedicated isolation and processing area to prevent it from mixing with normal reagents and causing potential risks. In addition, the system will automatically generate a detailed abnormal operation log, recording relevant information about the incident, including time, location, and specific problem description, to facilitate subsequent review and the formulation of corrective measures. This mechanism effectively ensures the security and stability of the system, prevents unqualified reagents from entering the workflow, and thus maintains the accuracy and credibility of water quality monitoring.

[0056] In some embodiments of the present application, in step 103, the implementation process of controlling the robotic arm to call the target reagent bottle matching the detection task and move it to the insertion and removal station for fixation according to the label information and the detection task instructions includes but is not limited to the following steps.

[0057] Step 301: Receive and parse the detection task instruction, extract the target detection item and the corresponding target reagent concentration.

[0058] In step 301, the system first receives the task instructions and parses them to extract the target test items and the required target reagent concentration. This process is the foundation of the entire operation process, ensuring that all subsequent steps are centered around the specific test requirements. By accurately parsing the task instructions, the system can clearly understand the specific test items to be performed and the specific reagent requirements, providing the necessary information support for accurately selecting the appropriate reagent bottle.

[0059] Step 302 : Based on the target detection item, the fields corresponding to the applicable detection items in the label information are matched to screen out suitable candidate reagent bottles.

[0060] In step 302, the system matches the applicable test item field in the label information with the target test item extracted from the test task instruction, screening out candidate reagent bottles that meet the criteria. This step is significant in that it narrows the selection range, retaining only those reagent bottles applicable to the current test item, improving the efficiency and accuracy of subsequent processing. This precise matching avoids the use of inappropriate reagents and ensures the validity and reliability of test results.

[0061] Step 303 : Perform verification on the candidate reagent bottle to verify whether its reagent concentration matches the target reagent concentration.

[0062] In step 303, the system further verifies the selected candidate reagent bottles, primarily to verify that their concentrations meet the target concentration requirements. This step is crucial to ensuring that the concentrations within the selected bottles meet the precise requirements of the test task. Any deviation in concentration could distort or invalidate the test results. Through rigorous concentration verification, the system can effectively eliminate unqualified reagent bottles, ensuring that the final reagent used fully meets the standards.

[0063] Step 304 : Among the candidate reagents that have passed the verification, the reagent bottle with the latest validity period is selected as the target reagent bottle according to the remaining validity period sorting strategy.

[0064] In step 304, the system prioritizes the reagent bottles with the closest remaining expiration dates among the candidate reagent bottles that have passed validation based on a ranking strategy. This step optimizes inventory management by preventing reagents from becoming ineffective due to prolonged storage and not being used promptly. This strategy not only helps improve resource utilization but also ensures that each reagent is in optimal condition, maximizing the accuracy and reliability of test results.

[0065] Step 305 : According to the designated partition where the target reagent bottle is located, the robot arm is controlled to call the target reagent bottle and move it to the insertion and removal station for fixation.

[0066] In step 305, the system controls the robotic arm to precisely retrieve the target reagent bottle based on its designated zone and safely and stably transfers it to the insertion and removal station for securement. This process is crucial to ensuring the efficient operation of the automated system. It seamlessly transitions from theoretical planning to actual operation, ensuring that each step is executed smoothly according to the pre-set plan, thereby improving overall work efficiency and operational precision.

[0067] In some embodiments of the present application, in step 104, the pinhole tube is controlled to perform an insertion operation on the target reagent bottle on the insertion station, the reagent in the target reagent bottle is taken out, and the process of recording the reagent taking data and synchronizing it to the cloud platform includes but is not limited to the following steps.

[0068] Step 401: Control the pinhole tube to insert into the reagent bottle according to the reagent type and its corresponding preset insertion and removal operation parameters, and monitor the insertion resistance in real time.

[0069] In step 401, the system guides the pinhole tube into the target reagent bottle based on the reagent type and its corresponding preset insertion and removal parameters, and monitors the cannula resistance in real time during the insertion process. The key to this step is to ensure that the pinhole tube can smoothly enter the reagent bottle while monitoring changes in resistance encountered during the cannula insertion process to promptly detect abnormalities. Real-time monitoring of cannula resistance helps prevent potential problems such as blockage or misinsertion, thereby ensuring the safety and success rate of the sampling process.

[0070] Step 402: If the intubation resistance exceeds a preset intubation resistance threshold, an emergency needle withdrawal procedure is triggered and a blockage alarm signal is generated.

[0071] In step 402, if the resistance detected during intubation exceeds a preset threshold, an emergency needle removal procedure is triggered and a blockage alarm is generated. This measure is intended to protect the device from damage and immediately notify the operator for inspection and maintenance. By setting a reasonable resistance threshold and implementing an emergency response mechanism, potential problems can be identified and resolved immediately, reducing unnecessary losses and delays and maintaining normal system operation.

[0072] Step 403: After the reagent in the target reagent bottle is taken out, the pinhole tube is controlled to exit the target reagent bottle at a uniform speed, and the reagent taking data is recorded and synchronized to the cloud platform.

[0073] In step 403, after the reagent in the target reagent bottle is removed, the system controls the pinhole tube to withdraw the reagent bottle at a constant speed and records the relevant data of this operation (such as the amount removed and the time), and then synchronizes this data to the cloud platform. The significance of this step is to achieve permanent data preservation and convenient access, facilitating future query, analysis, and quality traceability. Real-time recording and cloud synchronization not only enhance the transparency and reliability of data management, but also provide solid data support for continuous improvement.

[0074] Secondly, refer to Figures 2 to 4 The present invention provides an automated reagent management device, including a central controller, a reader, a robotic arm, a pinhole tube insertion mechanism, and a reagent storage rack. The central controller is used to control the reader, the robotic arm, and the pinhole tube insertion mechanism. The central controller is also used to receive reagent inventory information fed back by the reagent storage rack. In some embodiments of the present application, the reader is an industrial-grade corrosion-resistant reader designed specifically for the high humidity and corrosive environment of a water quality monitoring station.

[0075] In some embodiments of the present application, the robotic arm is a multi-degree-of-freedom robotic arm.

[0076] The central controller includes a processor and a memory, wherein the memory stores a program executable by the processor. The processor is configured to execute the following modules: a label scanning module, a reagent storage module, a reagent calling module, and a reagent insertion module.

[0077] The label scanning module is used to control the reader to scan and obtain the label information on the reagent bottle. The label information includes the reagent type, reagent concentration, reagent expiration date and applicable test items corresponding to the reagent in the reagent bottle.

[0078] The label scanning module ensures that the identity of each bottle of reagent can be quickly and accurately identified, providing basic data support for subsequent classification, storage, and retrieval. Through automated label scanning, the possibility of manual input errors can be effectively reduced, ensuring the accuracy and reliability of data.

[0079] If the label information is valid, the reagent storage module will control the robotic arm to classify and store the reagent bottles in the designated partitions. Otherwise, an alarm will be triggered and the robotic arm will be controlled to transport them to the isolation processing area.

[0080] Once the label information is confirmed to be valid, the reagent storage module takes effect, controlling the robotic arm to sort and store the reagent bottles into designated partitions based on the label details. If the label information is invalid, an alarm is triggered and the robotic arm is directed to transport the problematic reagent bottles to an isolated processing area. This module is crucial for efficient and organized inventory management, ensuring that all available reagents are properly stored in the most appropriate location for rapid subsequent retrieval and use. Furthermore, the timely isolation of unqualified reagents ensures the safety and accuracy of the system.

[0081] The reagent calling module is used to control the robotic arm to call the target reagent bottle that matches the detection task according to the label information and the instructions of the detection task, and move it to the insertion and removal station for fixation.

[0082] The reagent call module ensures that the reagents used for each test are the most appropriate, fully meeting the specific requirements of the test project. This not only improves test accuracy but also maximizes the use of existing resources and minimizes waste. This precise matching mechanism also supports the operational needs of unmanned monitoring stations, making the entire process more intelligent and efficient.

[0083] The reagent insertion module is used to control the pinhole tube in the pinhole tube insertion mechanism to insert and remove the target reagent bottle on the insertion station, complete the removal of the reagent in the target reagent bottle, record the reagent removal data (such as the amount taken, time, etc.) and synchronize it to the cloud platform.

[0084] The reagent insertion and removal module not only achieves a high degree of automation for reagent removal, reducing the need for manual intervention and the potential for errors, but also provides a solid foundation for data traceability. By real-time monitoring and recording every operation, the authenticity and integrity of water quality monitoring data can be effectively guaranteed, further enhancing the scientific and standardized nature of the overall monitoring work.

[0085] In summary, the automated reagent management device provided in the embodiment of the present application coordinates the work of each module through a central controller, realizing full-process automated management from reagent identification, classified storage, precise calling to final retrieval, effectively improving work efficiency and data accuracy, while reducing the impact of human factors.

[0086] In some embodiments of the present application, the automated reagent management device further includes a flushing mechanism. The central controller further includes a pinhole tube flushing module. After the reagent in the target reagent bottle is removed, the pinhole tube flushing module controls the pinhole tube insertion mechanism to uniformly withdraw the pinhole tube from the target reagent bottle, and simultaneously initiates a flushing program to control the flushing mechanism to flush the pinhole tube.

[0087] After removing the reagent from the target reagent bottle, the pinhole tube flushing module first controls the pinhole tube insertion mechanism to withdraw the pinhole tube from the target reagent bottle at a uniform speed. This process ensures that the pinhole tube can be smoothly removed from the reagent bottle, avoiding liquid splashing or air inhalation caused by rapid removal, thereby maintaining a clean and safe working environment and preventing the possibility of cross contamination.

[0088] Next, the pinhole tube flushing module initiates the flushing process to prepare for the upcoming pinhole tube cleaning. This step ensures thorough cleaning of the pinhole tube interior through preset flushing parameters (such as water flow rate and flushing time). Proper flushing not only removes residual reagents but also prevents cross-contamination between reagent batches, which is crucial for maintaining high-precision test results.

[0089] The pinhole tube flushing module then directs the flushing mechanism to perform the actual flushing of the pinhole tube. During the flushing process, a suitable cleaning fluid is used, either through high-pressure spraying or other effective methods, to thoroughly remove any residue from the inner wall of the pinhole tube. This step is crucial to ensure that the pinhole tube is clean and free of contamination each time it is used, ensuring the accuracy and reliability of subsequent experimental data. Regular flushing also extends the life of the pinhole tube and reduces maintenance costs.

[0090] In some embodiments of the present application, an artificial intelligence model is embedded in a central controller. First, experimental data such as reagent type, usage amount, and storage conditions are collected and standardized to extract key features, such as reagent concentration and storage location. Next, these features are optimized using feature engineering to ensure the efficiency and accuracy of the input data. Subsequently, a suitable machine learning algorithm (such as a random forest or neural network) is selected and the model is trained using historical data, and the parameters are optimized to improve prediction accuracy. After training, the model's prediction results are verified through experiments, and the parameters are adjusted based on the verification feedback to further optimize the model. Finally, the verified AI model is integrated into the central controller to achieve real-time monitoring and optimization of the automated reagent retrieval equipment, and anomaly detection and early warning are performed in combination with sensor data, thereby improving the system's intelligence level and operational reliability, ensuring the efficient operation of the entire process and the accuracy of the data. This integration not only enhances the automation and intelligence of laboratory management, but also significantly improves the reliability and efficiency of detection work.

[0091] In some embodiments of the present application, the pinhole tube insertion and removal mechanism includes a pinhole tube and a pressure sensor. The pinhole tube is made of polytetrafluoroethylene and has a retractable structure. The pressure sensor is used to monitor the intubation resistance in real time. If the intubation resistance exceeds a preset intubation resistance threshold, an emergency needle removal procedure is triggered and a blockage alarm signal is generated.

[0092] Pinhole tubing is made of polytetrafluoroethylene (PTFE), a material widely used in laboratory equipment for its exceptional chemical stability and corrosion resistance. PTFE is not only resistant to corrosion from most chemical reagents but also exhibits excellent biocompatibility, ensuring no contamination or reaction with reagents, thus guaranteeing the accuracy of experimental results. Furthermore, the pinhole tubing's retractable design allows it to accommodate reagent bottles of varying heights and shapes, enhancing the system's flexibility and applicability, making it easier to operate in a variety of complex working environments.

[0093] During the pinhole tube insertion process, a pressure sensor monitors changes in intubation resistance in real time. This allows the system to instantly detect any anomalies, such as blockages or other obstructions, in the pinhole tube. The use of pressure sensors effectively improves operational safety and reliability by providing early warning signals before potential problems occur. This real-time monitoring mechanism is crucial for ensuring the smooth operation of the automated process, ensuring that each insertion and removal operation is completed smoothly according to preset parameters, and avoiding operational failures or equipment damage due to unforeseen issues.

[0094] When the pressure sensor detects that the intubation resistance exceeds the preset threshold, the system automatically triggers the emergency needle withdrawal procedure and immediately generates a blockage alarm signal. The significance of this mechanism is to quickly respond to any unexpected situation that may affect operational safety or the accuracy of results. For example, if the pinhole tube encounters obstacles such as hard impurities or a deformed bottle mouth, excessive intubation resistance may cause damage to the pinhole tube or prevent correct sampling. By setting a reasonable resistance threshold and implementing emergency response measures, these problems can be identified and resolved at the first time, reducing unnecessary losses and delays and maintaining the normal operation of the system. At the same time, the generation of alarm signals also helps to notify operators in a timely manner for inspection and maintenance, further enhancing the reliability and safety of the system.

[0095] In some embodiments of the present application, infrared sensors, liquid level sensors, partition markers, and positioning calibration markers are arranged in the partition storage slots of the reagent storage rack.

[0096] In some embodiments of the present application, the infrared sensor includes an infrared laser scanning sensor and an infrared spectrum sensor. The infrared sensor is used to detect in real time whether the reagent bottle is in place and whether there is a crack in the bottle body. If there is a crack in the reagent bottle body, the reagent bottle damage alarm is triggered. The infrared sensor is arranged in the partition storage slot of the reagent storage rack, and is used to detect in real time whether the reagent bottle on each storage position is correctly placed and whether there is a crack in the bottle body. This real-time monitoring ensures that the system can immediately detect any reagent bottle that is not stored correctly or damaged, thereby avoiding the risk of leakage or other safety hazards caused by cracks in the bottle body. Once a crack in the bottle body is detected, the system will trigger a reagent bottle damage alarm to remind the operator to deal with the problem in a timely manner, which not only ensures the safety of the equipment and the environment, but also prevents potential reagent contamination.

[0097] The liquid level sensor is used to monitor the remaining liquid volume in the reagent bottle. If the remaining liquid volume is lower than the preset remaining liquid volume threshold, a low remaining amount warning and replenishment notification will be triggered. The liquid level sensor is responsible for monitoring the remaining liquid volume in each reagent bottle to ensure that the system can accurately grasp the available status of each reagent. When the liquid level sensor detects that the remaining liquid volume of a reagent bottle is lower than the preset threshold, the system will automatically trigger a low remaining amount warning and send a replenishment notification. This mechanism helps to plan reagent replenishment in advance, avoid interruptions to experiments or testing due to reagent shortages, and improve the continuity and efficiency of laboratory operations. By accurately monitoring reagent usage, inventory management can also be optimized, waste can be reduced, and costs can be reduced.

[0098] Partition markings are used to identify reagent types. This allows for quick identification of reagent types within a specific area, making it easier to manage and locate. The presence of partition markings simplifies the robotic arm's operational logic, enabling it to more efficiently select the correct reagent bottle for the test task. Clear partition markings also help maintain good inventory order, ensuring that reagents are stored in order by category, facilitating daily management and inventory.

[0099] Positioning and calibration marks assist the robotic arm in achieving positioning and calibration. During automated operations, the robotic arm must move frequently to retrieve and place reagent bottles, making accurate positioning crucial for successful operations. Positioning and calibration marks provide a reliable reference point, helping the robotic arm adjust its position to ensure accurate and precise positioning every time. This approach not only improves the overall accuracy of the system but also enhances operational stability, reducing the risk of operational failure or equipment damage due to positioning errors. By using positioning and calibration marks, the entire automated system can operate more efficiently and stably.

[0100] In some embodiments of the present application, the robotic arm is equipped with an environmental perception sensor group for acquiring environmental information to generate path planning instructions and obstacle avoidance instructions through artificial intelligence algorithms.

[0101] In some embodiments of the present application, after obtaining environmental information through the environmental perception sensor group carried by the robotic arm, path planning instructions and obstacle avoidance instructions are generated through artificial intelligence algorithms, such as SLAM algorithms, which are key steps in achieving automated operations. These sensors collect data on the surrounding environment in real time, helping the system understand the layout of its workspace, including information such as the location, size, and shape of obstacles. Based on this data, the SLAM algorithm can dynamically create or update an environmental map and calculate the optimal path to guide the movement of the robotic arm. This capability enables the robotic arm to navigate autonomously in complex and changing working environments, ensuring efficient and safe operating procedures.

[0102] In some embodiments of the present application, the environmental perception sensor group includes at least one of the following: a lidar, a visual sensor, an inertial measurement unit, and a depth camera.

[0103] Laser radar (LiDAR) precisely measures distance by emitting a laser beam and measuring the time it takes for it to reflect back. In the embodiments of this application, LiDAR provides the robotic arm with highly accurate distance information, enabling it to construct a detailed three-dimensional model of its environment. This is particularly important for identifying obstacles and their locations, helping to generate accurate obstacle avoidance instructions and ensuring that the robotic arm does not collide with other objects while performing its tasks. Furthermore, LiDAR data provides the basis for path planning, enhancing the reliability and safety of the system.

[0104] Vision sensors use cameras to capture image information, providing the robotic arm with rich visual data. This data can be used to identify features such as color, shape, and texture, helping the robotic arm distinguish between different reagent bottles and other items within the work area. Vision sensors can also detect subtle changes, such as text or labels on reagent bottle labels, to assist in completing more sophisticated tasks. Combined with artificial intelligence algorithms, vision sensors can enhance the accuracy of environmental modeling, making path planning more precise, while supporting more complex operational requirements, such as automatically correcting deviations and optimizing movement paths.

[0105] The inertial measurement unit (IMU) contains an accelerometer and gyroscope, which can measure the acceleration and angular velocity of the robotic arm, and then calculate its position and attitude changes. In the embodiment of the present application, the IMU provides the robotic arm with instant attitude feedback, which is crucial for maintaining stability and precise control. Especially when moving quickly or performing fine-tuning operations, the IMU can help the robotic arm adjust its state in real time to avoid errors caused by external interference. By fusing data with other sensors, the IMU further improves the response speed and stability of the overall system.

[0106] Depth cameras can provide detailed information about the relative distances between objects and generate depth maps, which are particularly useful for understanding and processing objects in three-dimensional space. In an embodiment of the present application, a depth camera is used to supplement information from other sensors, especially when precise measurement or operation of complex structures is required. It can clearly distinguish between foreground and background objects, helping the robotic arm better understand its operating environment, especially when it comes to approaching or avoiding obstacles in narrow spaces. The data from the depth camera also supports more intelligent obstacle avoidance strategies, ensuring that the robotic arm can safely bypass obstacles without sacrificing efficiency.

[0107] In some embodiments of the present application, an automated reagent management device is combined with water quality monitoring equipment and applied to full-process unmanned reagent management of an automatic water quality monitoring station.

[0108] In some embodiments of the present application, the process of measuring water quality chromaticity based on the dilution multiple method using an automated reagent management device and water quality monitoring equipment includes but is not limited to the following steps.

[0109] (1) Prepare reagent bottles. Each bottle of reagent is affixed with an encrypted label that records the reagent type, concentration, production date, expiration date, and applicable test items, and is covered with a transparent anti-corrosion film to adapt to humid environments.

[0110] (2) Read these reagent bottles and put them into storage. The operation and maintenance personnel place the reagent bottles on the conveyor belt in the storage area, and the system automatically identifies the label information through the reader; if the information is valid, the central controller controls the multi-degree-of-freedom robotic arm to grab the reagent bottle and store it; if it is invalid (such as expired or damaged), an alarm is triggered and the multi-degree-of-freedom robotic arm is controlled to transport the reagent bottle to the isolation processing area.

[0111] (3) Dynamic reagent storage path planning is implemented based on the reagent type of the reagent bottle. The central controller matches the partition identification (e.g., ammonia nitrogen area, COD area) on the reagent storage rack based on the scanning results, and guides the multi-degree-of-freedom robotic arm to avoid obstacles through the SLAM algorithm, accurately moving the reagent bottle to the target partition storage slot.

[0112] (4) The reagent bottles are precisely positioned and calibrated according to the positioning calibration marks of the target partition storage slots. The storage slots are embedded with infrared positioning marks, and the multi-degree-of-freedom robotic arm end camera compares the positions in real time to ensure a placement accuracy of ±0.5mm and updates the inventory database (e.g., "Ammonia nitrogen reagent inventory +1").

[0113] (5) When the water quality monitoring equipment issues a detection task instruction (such as "start ammonia nitrogen detection"), the detection task is triggered. The central controller receives and parses the detection task instruction, extracts the target detection item and the corresponding target reagent concentration, matches the candidate reagent bottles that meet the conditions, and gives priority to selecting the reagent bottle with the latest expiration date as the target reagent bottle to reduce waste, and calls the corresponding position of the target reagent bottle.

[0114] (6) The central controller controls the multi-degree-of-freedom robotic arm to move the target reagent bottle to the insertion and removal station, and uses a fixed fixture to ensure that the bottle body is vertical.

[0115] (7) The central controller controls the pinhole tube mechanism to move along the guide rail to the top of the bottle mouth and resets the pressure sensor to zero. The linear motor in the pinhole tube mechanism drives the pinhole tube downward at a speed of 2 mm / s. The insertion depth is preset according to the reagent type of the target reagent bottle (e.g., 5 cm for ammonia nitrogen reagent).

[0116] If a problem is encountered during the operation (such as blockage of the bottle mouth), the pressure sensor will feedback that the intubation resistance exceeds the limit (exceeds 10N), triggering the emergency needle withdrawal program and generating a blockage alarm signal. The pinhole tube will be urgently retracted and an alarm will be sounded.

[0117] (8) After the liquid is collected, the pinhole tube is controlled to exit the target reagent bottle, and the water quality monitoring equipment automatically absorbs the reagent transported by the pinhole tube for analysis. After receiving the analysis completion signal, the central controller starts the flushing program, uses the flushing mechanism to clean the pinhole tube and pipeline with deionized water, and discharges the flushing wastewater into the waste liquid collection unit to prevent cross contamination.

[0118] (9) After the insertion and removal operation is completed, the data of the target reagent bottle is recorded, including the reagent batch, usage time, operator (if any), etc., and a "Reagent Usage Report" is automatically generated, which can be exported to Excel or PDF format.

[0119] (10) The central controller uploads data to the environmental protection supervision platform to achieve real-time monitoring of reagent inventory, 30-day expiration warning, and traceability of test data and reagent batches, ensuring the transparency and traceability of the entire process.

[0120] In some embodiments of the present application, the process of implementing ammonia nitrogen detection using an automated reagent management device and water quality monitoring equipment includes but is not limited to the following steps.

[0121] (1) The ammonia nitrogen colorimetric reagent bottle is put into storage. The operation and maintenance personnel put the ammonia nitrogen colorimetric reagent bottle (with an encrypted label) into the storage area.

[0122] (2) The reader automatically identifies the label information of the ammonia nitrogen colorimetric reagent bottle and verifies the reagent type, concentration, and expiration date. If the label information is valid, the system marks it as "Special Reagent for Ammonia Nitrogen Detection"; if it is expired or the label is damaged, an alarm is triggered and the bottle is transported to the isolation treatment area.

[0123] (4) Classified storage: The multi-degree-of-freedom robotic arm grabs the reagent bottle and moves it to the dedicated partition for ammonia nitrogen reagents on the storage rack according to the label information.

[0124] (5) The central controller receives and parses the instructions for the ammonia nitrogen detection task, preferentially selects the ammonia nitrogen colorimetric reagent bottle with the most recent validity period as the target reagent bottle, retrieves the position corresponding to the target reagent bottle, and sets the cycle and time for the ammonia nitrogen detection.

[0125] (6) The central controller controls the multi-degree-of-freedom robotic arm to move the target reagent bottle to the insertion and removal station, and uses a fixed fixture to ensure that the bottle body is vertical.

[0126] (7) The central controller controls the pinhole tube mechanism to move along the guide rail to the top of the bottle mouth and resets the pressure sensor to zero. The linear motor in the pinhole tube mechanism drives the pinhole tube downward at a speed of 2 mm / s, with an insertion depth of 5 cm.

[0127] (8) After the liquid is collected, the pinhole tube is controlled to exit the target reagent bottle, and the ammonia nitrogen detector automatically absorbs the reagent transported by the pinhole tube for analysis. If the test value is abnormal (such as exceeding the threshold), the system automatically marks it and recommends retesting.

[0128] (9) After receiving the analysis completion signal, the central controller starts the flushing program, uses the flushing mechanism to clean the pinhole tube and pipeline with deionized water, and discharges the flushing wastewater into the waste liquid collection unit to prevent cross contamination.

[0129] In some embodiments of the present application, if a reading fails during a certain insertion (due to a damaged label), the system pauses the process and flashes a warning light. The operation and maintenance personnel check the fault code through the remote terminal, manually replace the reagent bottle, and restart the process.

[0130] In some embodiments of the present application, the multi-degree-of-freedom robotic arm automatically performs positioning accuracy calibration once a month, and the sealing ring of the pinhole tube is replaced every quarter to ensure long-term reliability.

[0132] The automated reagent management method and device provided in the embodiment of the present application realizes rapid and accurate identification of reagent bottles through label scanning, and combines artificial intelligence algorithms with environmental perception sensor groups (such as lidar, visual sensors, inertial measurement units and depth cameras) to realize precise path planning and obstacle avoidance functions of the robotic arm, ensuring efficient classification storage and accurate call of reagents. The embodiment of the present application integrates pressure sensors and liquid level sensors to monitor intubation resistance and reagent residues in real time, promptly detect and handle abnormal situations, and ensure stable operation of the system. The full-process automated operation and pinhole tube flushing mechanism avoid cross contamination and improve the accuracy and reliability of experimental results. In addition, the embodiment of the present application also has data recording and cloud synchronization functions to ensure that the data of each operation is recorded in detail and uploaded to the cloud platform, enhancing the transparency and reliability of data management and supporting continuous improvement and quality traceability.

[0133] Furthermore, in the embodiments of the present application, durable materials (such as polytetrafluoroethylene) are used to manufacture pinhole tubes, and infrared sensors are used to detect the status of reagent bottles (such as whether there are cracks or whether the position is correct), effectively preventing safety hazards and reducing equipment maintenance needs and costs. Positioning and calibration marks assist the robotic arm in achieving precise positioning, improving the stability and accuracy of operations. These technical measures not only improve the work efficiency and data accuracy of water quality monitoring stations, but also effectively reduce the need for manual intervention and the errors that may be caused, providing strong technical support for the development of unmanned monitoring stations.
