Description

Technical Field

[0001] This application relates to the field of automated storage equipment technology, and in particular to a storage bin with an electrically operated lid and its control method. Background Technology

[0002] In precision fields such as laboratory testing, biopharmaceuticals, and sample bank management, there is a need for the safe and orderly storage and management of large numbers of numbered test tubes. Traditional storage boxes often rely on manual opening and closing of tube caps or use simple, uniform locking mechanisms, which suffer from low operational efficiency, susceptibility to human error, difficulty in accurately tracing the handling history of individual test tubes, and inability to seamlessly integrate with higher-level information management systems. Especially in environments requiring sterility, low temperature, or specific atmosphere protection, frequent and non-standard manual operations can not only contaminate samples but also fail to ensure the airtightness of each tube cap, affecting the quality of sample preservation and data integrity.

[0003] Currently, there are some semi-automatic or fully automatic sample storage devices, but they still have limitations in terms of independent and precise control of a single tube, full-process visual traceability of the operation, and deep integration with the upper-level management system. Summary of the Invention

[0004] The purpose of this application is to provide a storage box with an electric opening and closing function and its control method to solve the above-mentioned technical problems, aiming to realize the automation, precision and traceability of test tube opening and closing operation, and improve the safety, efficiency and informatization level of sample management.

[0005] In some embodiments of this application, a control method is provided. This method receives an instruction containing a target test tube identifier and operation type, locates the target mechanism and test tube using a pre-stored mapping relationship, and obtains their current status information for safety logic verification. After both verification and execution condition compliance checks pass, the corresponding electric cover mechanism is driven to perform the specified action. The entire execution process is protected by real-time motor protection and monitored by sensors. Finally, the system comprehensively determines the operation result based on the arrival confirmation signal from the actuator and the feedback signal from the material status sensor, and updates the system status record accordingly. This method constructs a complete control closed loop from instruction parsing, safety verification, drive execution to status feedback, and all key steps generate traceable structured logs.

[0006] In some embodiments of this application, by setting a dynamic safety pre-inspection step, obstacles on the operation path are detected in real time after the logic verification is passed and before the formal drive mechanism is started. The action is only performed after it is confirmed that there are no obstacles, which effectively prevents mechanical collisions and accidental damage and enhances the active safety protection capability of the system.

[0007] In some embodiments of this application, a control method for a storage bin with an electrically operated cover is provided, including:

[0008] Receive an operation instruction for a test tube with a target number, the operation instruction including the identification information of the test tube with the target number and the operation type; The target numbered test tube and its corresponding electric switch cap mechanism are located based on the identification information, and the current status information of the target numbered test tube is obtained. The operation type is logically verified against the current state information. If the verification passes, a driving instruction is generated. Before executing the drive instructions, an execution condition compliance check is performed; When the execution condition compliance check passes, the corresponding electric cover mechanism is driven to perform the cover opening and closing action corresponding to the operation type. Based on the execution feedback of the electric cover opening and closing mechanism, the system status record of the target numbered test tube is confirmed to be completed and updated.

[0009] In some embodiments of this application, when receiving an operation instruction for a target-numbered test tube, the operation instruction includes the identification information of the target-numbered test tube and the operation type, it includes: In response to user input or operation instructions issued by the host system, the operation instructions include target test tube identification information with a predetermined number of the target test tube; The central controller receives the operation command and converts the predetermined number into the corresponding physical location coordinates according to the pre-stored mapping relationship database. The mapping relationship database defines a unique correspondence between each number and the numbered test tube in the storage box and its electric opening and closing cover mechanism. Based on the physical location coordinates, the central controller locates and prepares to drive the electric switch cap mechanism corresponding to the target test tube.

[0010] In some embodiments of this application, when locating the target numbered test tube and its corresponding electric switch cap mechanism based on the identification information, and obtaining the current status information of the target numbered test tube, the process includes: Based on the positioning results, the central controller accesses the sensor system associated with the target test tube to obtain real-time signals reflecting the physical state of the target test tube; The real-time signal includes at least one or more of the following: a limit switch signal for indicating that the cover is in the open or closed position, and a proximity sensor signal for detecting whether there is a sample in the chamber. The central controller analyzes the real-time signals and generates current status information for logic verification.

[0011] In some embodiments of this application, when performing logical verification between the operation type and the current state information, the following is included: The central controller compares the requested operation type with the parsed current status information and executes the preset logical verification rules. The logical verification rules include: When the request is an open operation, verify whether the current status information simultaneously satisfies the conditions that the cover is in the closed state and the sample is in the in-situ state. When the request is a close operation, verify whether the current status information indicates that the cover is in the open state; Only when the aforementioned logic verification rules are met, the central controller sends a preset sequence of drive commands to the target electric switch cover mechanism to execute the corresponding opening or closing action.

[0012] Some embodiments of this application also include: After the logic verification rules are met and before the drive command sequence is sent to the target electric switch cover mechanism, the central controller also performs a dynamic safety pre-check. The dynamic safety pre-inspection includes: activating obstacle detection sensors set on the operation path of the target test tube for real-time detection; The central controller only sends the drive command sequence to execute the action after receiving a detection signal indicating that there are no obstacles; If an obstacle is detected, pause the current operation and issue a warning.

[0013] In some embodiments of this application, the execution condition compliance check performed before executing the driving instructions includes: After the logic verification is passed, the central controller sends a position query command to the target electric switch cover mechanism; In response to the position query command, the electric cover opening and closing mechanism acquires the real-time position signal of the telescopic rod through its integrated telescopic rod position sensor and feeds it back to the central controller. The central controller determines whether the telescopic rod is at the target mechanical limit position that matches the operation type based on the received real-time position signal and the operation type. Specifically, when the operation type is an opening operation, the target mechanical limit position is the fully retracted position; when the operation type is a closing operation, the target mechanical limit position is the fully extended position.

[0014] In some embodiments of this application, when the compliance check of the execution conditions passes, driving the corresponding electric cover mechanism to perform the cover opening and closing action corresponding to the operation type includes: If the central controller determines that the telescopic rod is at the target mechanical limit position, it generates a drive command corresponding to the operation type and drives the cover execution component of the electric switch cover mechanism to complete the action of opening or closing the cover of the target numbered test tube. If it is determined that the telescopic rod is not at the target mechanical limit position, the central controller stops the subsequent opening and closing cover driving process, generates and records a fault message indicating that the telescopic rod position is abnormal, and sends a warning notification containing the target number test tube identification information to the user interface or the host system.

[0015] In some embodiments of this application, when confirming the completion of the action and updating the system status record of the target numbered test tube based on the execution feedback of the electric cover mechanism, the following steps are included: After the cover actuator is driven to move, the central controller receives a cover positioning confirmation signal from the electric cover mechanism. Based on the cover positioning confirmation signal, it is confirmed that the mechanical action of opening and closing the cover has been completed; Simultaneously, it receives the detection signal from the piezoelectric sensor at the bottom of the target numbered test tube, and determines whether there is a change in the material state based on whether an effective pressure signal mapped by the threshold is received. Based on the confirmation of the completion of the mechanical action and the judgment of the material status, update the cap status and material presence status of the target numbered test tube in the system status record.

[0016] Some embodiments of this application also include real-time motor protection: The central controller monitors the drive current of the motor in real time; If the drive current is detected to continuously exceed the preset safety threshold for a first duration, it is determined that a stall has occurred, the motor power is immediately cut off, and a motor stall fault record is generated. If the driving current does not exceed the limit during operation and falls back to the no-load current range within the second time period, the operation is determined to be completed normally.

[0017] In some embodiments of this application, a storage bin with an electrically operated lid includes: The box contains multiple independently numbered test tubes for holding different test tubes. Multiple electrically operated cap opening and closing mechanisms are provided, corresponding to the numbered test tubes, to drive the opening or closing of the caps of the corresponding numbered test tubes; The sensor system is installed at each numbered test tube to collect physical signals in real time that reflect the opening and closing status of the cover and the presence of materials. The central controller is electrically connected to the plurality of electrically operated cover mechanisms and the sensor system, respectively. A memory, connected to the central controller, is used to store data.

[0018] Compared with the prior art, the storage bin with an electrically operated cover and its control method provided in this application have the following advantages: This method achieves precise and automated management of individual test tube cap opening and closing operations by constructing a complete closed-loop control process from command reception, status verification, action execution to process recording and feedback confirmation. This method not only achieves rapid and accurate positioning based on the test tube identifier and pre-stored mapping relationship, but also ensures that each operation is based on the current actual physical state through multiple state logic verifications and real-time sensor signal analysis. This effectively prevents misoperation, duplicate operation, and state conflicts, significantly improving the reliability and operational safety of sample storage and retrieval.

[0019] Figure 1 This is a flowchart illustrating a control method for a storage bin with an electrically operated cover in a preferred embodiment of this application. Detailed Implementation

[0020] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, they should not be construed as limitations on this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] like Figure 1 As shown, a control method for a storage bin with an electrically operated cover in a preferred embodiment of this application includes: Receive an operation instruction for a test tube with a target number, the operation instruction including the identification information of the test tube with the target number and the operation type; The target numbered test tube and its corresponding electric switch cap mechanism are located based on the identification information, and the current status information of the target numbered test tube is obtained. The operation type is logically verified against the current state information. If the verification passes, a driving instruction is generated. Before executing the drive instructions, an execution condition compliance check is performed; When the execution condition compliance check passes, the corresponding electric cover mechanism is driven to perform the cover opening and closing action corresponding to the operation type. Based on the execution feedback of the electric cover opening and closing mechanism, the system status record of the target numbered test tube is confirmed to be completed and updated.

[0025] In some embodiments of this application, when receiving an operation instruction for a target-numbered test tube, the operation instruction includes the identification information of the target-numbered test tube and the operation type, it includes: In response to user input or operation instructions issued by the host system, the operation instructions include target test tube identification information with a predetermined number of the target test tube; The central controller receives the operation command and converts the predetermined number into the corresponding physical location coordinates according to the pre-stored mapping relationship database. The mapping relationship database defines a unique correspondence between each number and the numbered test tube in the storage box and its electric opening and closing cover mechanism. Based on the physical location coordinates, the central controller locates and prepares to drive the electric switch cap mechanism corresponding to the target test tube.

[0026] In this embodiment, user input refers to manual operation instructions received through the storage bin itself or a human-machine interface directly connected to it. The human-machine interface includes, but is not limited to, a touchscreen, buttons, or a barcode scanner. This method is suitable for on-site operators to directly select target test tubes and trigger the opening and closing of the caps. Upper-level system dispatch: This refers to receiving remote control instructions from a higher-level management system via a communication interface, such as a Laboratory Information Management System (LIMS), a material scheduling system, or an automated production line control host. This method is suitable for integrated and automated workflows, enabling unattended operation or remote dispatch. By supporting both instruction sources, the system possesses both the flexibility of local operation and the ability to collaborate with higher-level management systems, improving the overall automation and informatization level of the operation.

[0027] In this embodiment, the mapping from logical numbers to physical entities is the core. The central controller maintains a pre-stored mapping database. This database is a structured collection whose core function is to establish and maintain a strict one-to-one correspondence between the logical numbers of test tubes and all physical entities within the storage box, which is crucial for achieving precise control. Specific mapping relationships include: Number-Location Mapping: Each test tube number uniquely corresponds to its physical location coordinates within the storage box frame. Number-Mechanism Mapping: Each test tube number uniquely associates with an identifier for the electrically operated lid opening / closing mechanism responsible for its lid operation. Number-Sensor Mapping: Each test tube number uniquely associates with the logical address of the sensor required for its status monitoring.

[0028] In this embodiment, the operation instructions originate from user input or are issued by the host system to support both local and remote control modes. After receiving the instruction, the central controller sequentially executes the following steps: extracting the target test tube's logical number and operation type from the instruction; using this logical number as an index to query the mapping database and convert it into the corresponding target physical location coordinates and the target electric cap switch mechanism identifier; based on the obtained physical location coordinates, the system logically locates the target test tube; simultaneously, the central controller locks the corresponding target electric cap switch mechanism, allocates control resources to it, loads the corresponding preset drive parameters, and enters a standby state. At this point, the system has completed the conversion from abstract instructions to specific execution targets, preparing for subsequent state safety verification and action-driven execution processes.

[0029] In some embodiments of this application, when locating the target numbered test tube and its corresponding electric switch cap mechanism based on the identification information, and obtaining the current status information of the target numbered test tube, the process includes: Based on the positioning results, the central controller accesses the sensor system associated with the target test tube to obtain real-time signals reflecting the physical state of the target test tube; The real-time signal includes at least one or more of the following: a limit switch signal for indicating that the cover is in the open or closed position, and a proximity sensor signal for detecting whether there is a sample in the chamber. The central controller analyzes the real-time signals and generates current status information for logic verification.

[0030] In this embodiment, based on the positioning result, accessing the sensor system associated with the target test tube includes: the central controller using the physical location coordinates or corresponding hardware address determined in previous steps. The central controller actively sends data requests to the specific sensor group serving the target test tube or directly reads its signal ports through a predefined communication protocol. Furthermore, the sensors are not globally shared, but rather a set of local sensing units uniquely bound to each test tube and dedicated to monitoring the status of that test tube, based on the pre-stored mapping database.

[0031] In this embodiment, parsing the real-time signal is a crucial process for the central controller to transform the raw physical signal into information that can be understood and processed by the program. The parsing process involves the central controller interpreting and converting the raw signal according to preset rules, including identifying a high-level signal as a limit switch trigger state and identifying analog signals within a specific voltage range as an object approaching.

[0032] In this embodiment, after completing the positioning based on the identification information, the central controller immediately executes the status acquisition process. Specifically, based on the positioning result, the central controller accesses the sensor system associated with the target test tube. Using the determined hardware address, the controller actively reads the output of the set of sensors dedicated to monitoring the test tube via a digital input port or dedicated communication link. The sensor system provides real-time signals reflecting the physical state of the target test tube; these are raw electrical signals without logical processing, such as limit switch signals indicating whether the lid has reached its limit position, or proximity sensor signals detecting the presence of a sample in the cavity. The central controller parses the real-time signals. This process includes necessary noise reduction, level judgment, analog-to-digital conversion, and accurate interpretation of the raw signals into logical facts representing specific physical events, such as lid closed or sample approach. Finally, the controller generates current status information for logical verification, formatting the parsed results into explicit status variables such as lid status: closed, sample status: present. This structured current status information provides a direct and reliable basis for the next step of performing safety logic verification with operating instructions.

[0033] In some embodiments of this application, when performing logical verification between the operation type and the current state information, the following is included: The central controller compares the requested operation type with the parsed current status information and executes the preset logical verification rules. The logical verification rules include: When the request is an open operation, verify whether the current status information simultaneously satisfies the conditions that the cover is in the closed state and the sample is in the in-situ state. When the request is a close operation, verify whether the current status information indicates that the cover is in the open state; Only when the aforementioned logic verification rules are met, the central controller sends a preset sequence of drive commands to the target electric switch cover mechanism to execute the corresponding opening or closing action.

[0034] In this embodiment, after obtaining the operation type and current status information, the central controller will execute key logic verification steps. Specifically, this includes: when the request is for an open operation, verifying whether the current status information simultaneously satisfies the conditions of the lid being closed and the sample being in place; when the request is for a close operation, verifying whether the current status information indicates the lid is open. This dual confirmation of the lid being closed and the sample being in place is designed to ensure the validity of the operation and prevent repeated opening; the single confirmation of the lid being open is required for closing, ensuring the rationality of the action. This mechanism constitutes a basic state interlock. Executing the driving action has strict conditions; that is, the central controller will only enter the execution phase when the aforementioned logic verification rules are met. At this time, the controller will send a preset drive command sequence to the target electric lid opening / closing mechanism. This command sequence is a set of standardized control commands pre-tuned according to the mechanical characteristics of the mechanism. By sending this sequence and monitoring its execution, the controller ensures that the mechanism performs the corresponding, complete open or close action, that is, runs stably and reliably from the starting position to the target endpoint position.

[0035] Some embodiments of this application also include: After the logic verification rules are met and before the drive command sequence is sent to the target electric switch cover mechanism, the central controller also performs a dynamic safety pre-check. The dynamic safety pre-inspection includes: activating obstacle detection sensors set on the operation path of the target test tube for real-time detection; The central controller only sends the drive command sequence to execute the action after receiving a detection signal indicating that there are no obstacles; If an obstacle is detected, pause the current operation and issue a warning.

[0036] In this embodiment, a dynamic safety pre-check step is added after the logic verification passes and before the formal drive mechanism. Specifically, the dynamic safety pre-check includes: activating obstacle detection sensors installed on the target test tube's operating path for real-time detection. The central controller temporarily activates a sensor specifically designed to monitor for foreign object intrusion within the target test tube cap's movement trajectory area and acquires its instantaneous detection data. The central controller only sends the drive command sequence to execute the action after receiving a detection signal indicating no obstacle. Conversely, if an obstacle is detected, the central controller immediately pauses the current operation and issues a warning, notifying the user to remove the obstacle, thereby effectively preventing mechanical collisions, sample damage, or personal safety hazards caused by accidental obstruction or intrusion.

[0037] In some embodiments of this application, the execution condition compliance check performed before executing the driving instructions includes: After the logic verification is passed, the central controller sends a position query command to the target electric switch cover mechanism; In response to the position query command, the electric cover opening and closing mechanism acquires the real-time position signal of the telescopic rod through its integrated telescopic rod position sensor and feeds it back to the central controller. The central controller determines whether the telescopic rod is at the target mechanical limit position that matches the operation type based on the received real-time position signal and the operation type. Specifically, when the operation type is an opening operation, the target mechanical limit position is the fully retracted position; when the operation type is a closing operation, the target mechanical limit position is the fully extended position.

[0038] In this embodiment, to achieve traceability and auditing requirements for the operation process, the system simultaneously generates and saves a detailed structured operation record while driving the electric cover mechanism to perform its actions. This record is automatically created and integrated by the central controller during the action execution process. When the central controller passes the verification and begins sending drive commands to the target electric cover mechanism, the system generates a unique record sequence for this specific operation instance and adds a precise start timestamp.

[0039] In this embodiment, the core content of the record originates from multi-source data within the system, integrating key control information and status feedback information for this operation. Specifically, this includes: the unique identifier of the target test tube, the type of operation requested and executed, the time when the operation command was issued, the time when the drive command was issued, and the status signals characterizing the action execution result from relevant sensors and their change times. After the record is generated, the central controller associates and encapsulates all the above discrete data elements to form a structured log entry. This entry not only records the operation content but also objectively records the time sequence and final state, thereby completely reconstructing the control closed loop from command issuance to action completion.

[0040] Through this mechanism, the system automatically generates an electronic record for every opening and closing of the cap on each test tube in the storage bin, containing clear operational semantics, precise time coordinates, and verifiable status results. This data log-based traceability method effectively improves the transparency, reliability, and auditability of the sample management process, providing a solid data foundation for process verification, troubleshooting, and quality management.

[0041] In some embodiments of this application, when the compliance check of the execution conditions passes, driving the corresponding electric cover mechanism to perform the cover opening and closing action corresponding to the operation type includes: If the central controller determines that the telescopic rod is at the target mechanical limit position, it generates a drive command corresponding to the operation type and drives the cover execution component of the electric switch cover mechanism to complete the action of opening or closing the cover of the target numbered test tube. If it is determined that the telescopic rod is not at the target mechanical limit position, the central controller stops the subsequent opening and closing cover driving process, generates and records a fault message indicating that the telescopic rod position is abnormal, and sends a warning notification containing the target number test tube identification information to the user interface or the host system.

[0042] In some embodiments of this application, when confirming the completion of the action and updating the system status record of the target numbered test tube based on the execution feedback of the electric cover mechanism, the following steps are included: After the cover actuator is driven to move, the central controller receives a cover positioning confirmation signal from the electric cover mechanism. Based on the cover positioning confirmation signal, it is confirmed that the mechanical action of opening and closing the cover has been completed; Simultaneously, it receives the detection signal from the piezoelectric sensor at the bottom of the target numbered test tube, and determines whether there is a change in the material state based on whether an effective pressure signal mapped by the threshold is received. Based on the confirmation of the completion of the mechanical action and the judgment of the material status, update the cap status and material presence status of the target numbered test tube in the system status record.

[0043] In this embodiment, after the lid opening and closing action is executed, the system enters a critical confirmation and status update phase to ensure the closed loop of the control logic. After the central controller issues the drive command, it simultaneously starts monitoring two key feedback channels: one is the lid positioning confirmation signal from the target electric lid opening and closing mechanism body, which is used to directly confirm whether the telescopic rod has moved to the target mechanical limit position required by the command; the other is the detection signal from the piezoelectric sensor at the bottom of the target numbered test tube, which is used to indirectly sense whether the weight inside the test tube has changed due to the insertion or removal operation.

[0044] In this embodiment, the system's confirmation logic is based on a comprehensive analysis of the aforementioned signals. First, the controller must continuously receive a valid cover-in confirmation signal, which serves as the primary criterion for determining whether the mechanical action has been completed. Simultaneously, the controller analyzes the piezoelectric sensor signal: by comparing the detected analog signal with a preset weight change threshold, it determines whether a valid pressure signal jump has occurred. This jump is a key indicator for determining whether material has been stored or removed.

[0045] In this embodiment, the final state update is the result of a comprehensive judgment. The central controller combines mechanical positioning confirmation with material status judgment, and updates the cap status and material presence status of the target-numbered test tube in the system's internal records accordingly. For example, a successful cap opening and sampling operation should ultimately be updated to a state where the cap is open and the material is not present. Through this mechanism, each operation is transformed into a series of sensor event records with clear timestamps and logical connections. The system establishes an auditable operation log for each test tube based on multi-sensor data verification. This achieves reliable synchronization between physical operation results and digital management status, ensuring process traceability.

[0046] Some embodiments of this application also include real-time motor protection: The central controller monitors the drive current of the motor in real time; If the drive current is detected to continuously exceed the preset safety threshold for a first duration, it is determined that a stall has occurred, the motor power is immediately cut off, and a motor stall fault record is generated. If the driving current does not exceed the limit during operation and falls back to the no-load current range within the second time period, the operation is determined to be completed normally.

[0047] In this embodiment, the system's final confirmation of the operation execution result relies strictly on real-time analysis of the drive motor status and feedback signals from the end sensors, and performs corresponding status management accordingly. Throughout the entire process of the drive motor performing the cover opening and closing action, the central controller simultaneously implements two key monitoring channels: one is real-time monitoring of the motor's drive current, and the other is continuous reception of feedback signals from the cover positioning sensor and piezoelectric sensor. The system determines the final result of the operation based on these direct electrical and mechanical signals. Its confirmation and processing logic is as follows: The system determines the operation is successful when all of the following conditions are met: The motor drive current does not exceed the preset safety threshold during operation. The current smoothly returns to the no-load current range within the preset second time period, indicating that the mechanical load has been removed. A valid cover positioning confirmation signal is received, proving that the mechanical action has reached the target position. The piezoelectric sensor signal change matches the expected operation type. At this time, the central controller will update the cover status and material presence status in the system status record as usual.

[0048] The system determines operation failure under any of the following circumstances: Motor stall fault: The drive current continuously exceeds the preset safety threshold for a first duration. The controller immediately cuts off motor power and generates a motor stall fault record. Action not in place fault: No confirmation signal of cover placement is received within the preset time. Position pre-check abnormality: During the execution condition compliance check phase, it is found that the telescopic rod is not at the expected initial mechanical limit position. In this case, the system will prohibit updating the normal working status of the target test tube to prevent logical confusion. Simultaneously, a detailed fault record containing the specific fault type, target test tube identifier, and timestamp is generated and sent to the user interface or upper-level system to trigger an alarm and guide intervention.

[0049] For certain non-critical, tolerable anomalies, the system can add additional flags after determining that the main action was successful. For example, if the action is successfully completed, but the motor peak current is close to but does not exceed the safety threshold, or the action time is slightly longer than the typical value, the system can associate a performance deviation flag in the operation log for subsequent statistical analysis or preventive maintenance, but this will not affect the immediate availability of the test tube.

[0050] Through the above mechanism, the system constructs a hierarchical operation result management system based on direct electrical and mechanical feedback. It ensures the accuracy of status updates and achieves reliable process traceability and system maintainability through structured fault records and anomaly markers.

[0051] In some embodiments of this application, a storage bin with an electrically operated lid includes: The box contains multiple independently numbered test tubes for holding different test tubes. Multiple electrically operated cap opening and closing mechanisms are provided, corresponding to the numbered test tubes, to drive the opening or closing of the caps of the corresponding numbered test tubes; The sensor system is installed at each numbered test tube to collect physical signals in real time that reflect the opening and closing status of the cover and the presence of materials. The central controller is electrically connected to the plurality of electrically operated cover mechanisms and the sensor system, respectively. A memory, connected to the central controller, is used to store data.

[0052] This application provides a storage bin with an electrically operated lid-opening function. Through mechatronics design, the storage bin achieves independent, automated control and status management of the lids of multiple numbered test tubes inside. The storage bin includes a main body. Inside the body are multiple independently numbered test tubes, each used to hold sample test tubes. Each numbered test tube has a unique logical identifier in the system and corresponds to a fixed physical storage location. For each numbered test tube, an electrically operated lid-opening mechanism is provided. Each mechanism is independently controlled to precisely drive the lid of its corresponding numbered test tube, performing the mechanical action of opening or closing. The storage bin is equipped with a distributed sensor system. Various sensors in this system are located at key positions on each numbered test tube to collect physical signals reflecting the open / closed state of the test tube lid and the presence of materials in real time. The core control unit of the storage bin is a central controller. This controller is electrically connected to all the electrically operated lid-opening mechanisms and the sensor system via electrical circuits. The central controller is responsible for receiving and processing operation commands and sensor signals, making decisions based on predetermined control logic, and issuing drive commands to the designated electrically operated lid-opening mechanisms. The storage bin also includes a memory connected to the central controller, which is used to store data required for system operation, such as a mapping database, operation logs, status records, and fault information.

[0053] Through the coordinated operation of the aforementioned hardware components, the central controller can accurately locate the target test tube according to instructions, obtain its current status, drive the corresponding mechanism to perform actions after verification, and update the system status based on sensor feedback, thus forming a complete, reliable and traceable automated storage bin system.

[0054] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.

The mapping relationship database defines a unique correspondence between each number and the numbered test tube in the storage box and its electric opening and closing cover mechanism. Based on the physical location coordinates, the central controller locates and prepares to drive the electric switch cap mechanism corresponding to the target test tube.

3. The control method for a storage bin with an electrically operated cover as described in claim 2, characterized in that, When locating the target numbered test tube and its corresponding electric switch cap mechanism based on the identification information, and obtaining the current status information of the target numbered test tube, the process includes: Based on the positioning results, the central controller accesses the sensor system associated with the target test tube to obtain real-time signals reflecting the physical state of the target test tube; The real-time signal includes at least one or more of the following: a limit switch signal for indicating that the cover is in the open or closed position, and a proximity sensor signal for detecting whether there is a sample in the chamber. The central controller analyzes the real-time signals and generates current status information for logic verification.

4. The control method for a storage bin with an electrically operated cover as described in claim 3, characterized in that, When performing logical verification between the operation type and the current state information, the following are included: The central controller compares the requested operation type with the parsed current status information and executes the preset logical verification rules. The logical verification rules include: When the request is an open operation, verify whether the current status information simultaneously satisfies the conditions that the cover is in the closed state and the sample is in the in-situ state. When the request is a close operation, verify whether the current status information indicates that the cover is in the open state; Only when the aforementioned logic verification rules are met, the central controller sends a preset sequence of drive commands to the target electric switch cover mechanism to execute the corresponding opening or closing action.

5. The control method for a storage bin with an electrically operated cover as described in claim 4, characterized in that, Also includes: After the logic verification rules are met and before the drive command sequence is sent to the target electric switch cover mechanism, the central controller also performs a dynamic safety pre-check. The dynamic safety pre-inspection includes: activating obstacle detection sensors set on the operation path of the target test tube for real-time detection; The central controller only sends the drive command sequence to execute the action after receiving a detection signal indicating that there are no obstacles; If an obstacle is detected, pause the current operation and issue a warning.

6. The control method for a storage bin with an electrically operated cover as described in claim 5, characterized in that, Before executing the driver instructions, the execution condition compliance check includes: After the logic verification is passed, the central controller sends a position query command to the target electric switch cover mechanism; In response to the position query command, the electric cover opening and closing mechanism acquires the real-time position signal of the telescopic rod through its integrated telescopic rod position sensor and feeds it back to the central controller. The central controller determines whether the telescopic rod is at the target mechanical limit position that matches the operation type based on the received real-time position signal and the operation type. Specifically, when the operation type is an opening operation, the target mechanical limit position is the fully retracted position; when the operation type is a closing operation, the target mechanical limit position is the fully extended position.

7. The control method for a storage bin with an electrically operated cover as described in claim 6, characterized in that, When the compliance check is passed, the corresponding electric cover mechanism is driven to perform the cover opening / closing action corresponding to the operation type, including: If the central controller determines that the telescopic rod is at the target mechanical limit position, it generates a drive command corresponding to the operation type and drives the cover execution component of the electric switch cover mechanism to complete the action of opening or closing the cover of the target numbered test tube. If it is determined that the telescopic rod is not at the target mechanical limit position, the central controller stops the subsequent opening and closing cover driving process, generates and records a fault message indicating that the telescopic rod position is abnormal, and sends a warning notification containing the target number test tube identification information to the user interface or the host system.

8. The control method for a storage bin with an electrically operated cover as described in claim 7, characterized in that, When confirming the completion of the action and updating the system status record of the target numbered test tube based on the execution feedback of the electric cap opening and closing mechanism, the process includes: After the cover actuator is driven to move, the central controller receives a cover positioning confirmation signal from the electric cover mechanism. Based on the cover positioning confirmation signal, it is confirmed that the mechanical action of opening and closing the cover has been completed; Simultaneously, it receives the detection signal from the piezoelectric sensor at the bottom of the target numbered test tube, and determines whether there is a change in the material state based on whether an effective pressure signal mapped by the threshold is received. Based on the confirmation of the completion of the mechanical action and the judgment of the material status, update the cap status and material presence status of the target numbered test tube in the system status record.

The control method for a storage bin with an electrically operated cover as described in claim 1, characterized in that, It also includes real-time motor protection: The central controller monitors the drive current of the motor in real time; If the drive current is detected to continuously exceed the preset safety threshold for a first duration, it is determined that a stall has occurred, the motor power is immediately cut off, and a motor stall fault record is generated. If the driving current does not exceed the limit during operation and falls back to the no-load current range within the second time period, the operation is determined to be completed normally.
