Description

Technical Field

[0001] The present invention relates to the field of industrial fluid transmission control and is applied in liquor production scenarios. In particular, it relates to an intelligent protection system and method for hose connections based on dynamic guidance and multi-stage interlocking. Background Art

[0002] In the production of baijiu (white liquor), the transfer and delivery of raw liquor is crucial for ensuring its quality. Traditionally, operators rely on visual identification of pipeline markings to connect hoses. This highly manual approach has gradually exposed systemic flaws in modern large-scale production. In increasingly complex production environments, operators must simultaneously connect dozens of hoses of varying specifications. Visual fatigue and bias are common when visually identifying pipeline numbers with similar characters. This human error not only causes cross-contamination between different liquors but can also lead to abnormalities in the quality of batches. In severe cases, this can compromise the flavor of the entire batch, resulting in significant financial losses and brand reputation risks for the company.

[0003] The existing technical system lacks an effective dynamic monitoring mechanism for the operation process, and the entire connection operation is in an open state. After the operator completes the pipeline connection, the system is unable to verify the compliance of the connection action in real time. Incorrect connections often need to wait for feedback from subsequent processes to be discovered. This lagging control mode means that incorrect operations may continue for hours or even longer, resulting in the expansion of the scope of contamination and an exponential increase in error correction costs. More seriously, incorrect connections may cause the unintended mixing of wines with different alcohol content and flavors, resulting in irreversible quality problems.

[0004] In terms of quality traceability, the traditional operating model relies on paper documents to record operational information, which has inherent defects such as incomplete records and information lags. When a quality accident occurs, it is difficult for managers to accurately trace back to the specific operation nodes, and the definition of responsibility often falls into the dilemma of multiple parties passing the buck. Some improvement plans try to use color identification rings or QR code labels to improve pipeline identification, but these static identification solutions fail to solve the problem of dynamic guidance during operation, cannot effectively constrain the operation path of operators, and the recognition efficiency is significantly reduced in dim environments or when the equipment surface is contaminated.

[0005] Current technological upgrades are primarily focused on improving single processes, and a comprehensive intelligent management and control system that encompasses the entire operational process has yet to be established. Existing solutions suffer from three common technical shortcomings: a lack of real-time guidance and correction mechanisms for operational behavior, preventing physical blocking of misoperations; a lack of a closed-loop linkage between operational data and quality traceability, preventing digital recording and traceability of key operational parameters; and the isolation of traditional identification systems from equipment control systems, with identification information not linked to actuators. These technical shortcomings have led to persistent quality control blind spots in the liquor delivery process, hindering the industry's transition to intelligent production. Summary of the Invention

[0006] This invention aims to address the limitations of traditional hose connection technology in liquor transportation, such as the risk of manual error and uncontrollable processes. Therefore, it proposes an intelligent hose connection protection system and method based on dynamic guidance and multi-level interlocking. This system integrates host computer simulation, dynamic light signal guidance, operational interlocking, and data traceability, enhancing error prevention during hose connection and optimizing liquor production efficiency.

[0007] The present invention adopts the following technical solutions to achieve the purpose:

[0008] A hose connection intelligent protection system based on dynamic guidance and multi-level interlocking includes a host computer simulation module and a field device module connected in communication. The field device module includes an explosion-proof indicator light module, an interlock control module, and an array connection guidance module; wherein:

[0009] The host computer simulation module is used to obtain the requirements of the liquor transportation task, dynamically generate a hose connection logic diagram based on the 3D pipeline topology model, obtain connection instructions, and sequentially send them to the field equipment modules. It also receives operation and status data fed back by the field equipment modules, generates and stores operation logs;

[0010] The explosion-proof indicator light module receives the light signal instructions output by the array connection guidance module and identifies different types of hose interfaces through different indicator light color codes. At the same time, the differentiated strobe patterns of each indicator light guide on-site workers in hose connection operations.

[0011] The interlock control module is used to lock the issuing channels of other connection instructions after the current connection instruction is issued and before the connection of the corresponding hose interface is confirmed, thereby locking the hose interfaces other than the hose interface corresponding to the current connection instruction;

[0012] The array connection guidance module is used to receive and parse connection instructions, generate light signal instructions and output them to the explosion-proof indicator light module to activate the corresponding indicator light; at the same time, after the hose interface is connected, its connection status is obtained, the matching of the connection status and the connection instruction is verified and feedback is provided.

[0013] Specifically, the host computer simulation module is used to determine the spatial logical relationship of pipeline components including pipes, valves, joints and hose interfaces based on the actual on-site pipeline structure mapped in the three-dimensional pipeline topology model, and then dynamically simulate the hose connection plan based on the requirements of the liquor transportation task, generate a hose connection logic diagram, and obtain connection instructions; the host computer simulation module is also used to issue an external alarm when the matching check between the connection status and the connection instruction fails.

[0014] Furthermore, the explosion-proof indicator light module has an explosion-proof shell and a built-in intrinsically safe LED light group, and adopts an IP67 protection structure; the intrinsically safe LED light group is equipped with multiple groups of two-color LED indicator lights, and the position of one group of two-color LED indicator lights is set corresponding to the position of one hose interface.

[0015] Preferably, the types of pipeline connection points corresponding to the hose interface are divided into two categories, one is the front connection point of the pump, and the other is the rear connection point or jumper point of the pump; the two-color LED indicator light is used to identify the pipeline connection point type of the hose interface at its location through two different colors.

[0016] Preferably, the explosion-proof indicator light module is used to make the two-color LED indicator light corresponding to the hose interface that needs to be connected to the hose flash at a low frequency according to the light signal instruction; for the hose interface that needs to be disconnected, the two-color LED indicator light corresponding to the hose interface flash at a high frequency; when the liquor transportation task is in progress, the two-color LED indicator light corresponding to the hose interface that has been connected is always on.

[0017] Furthermore, the interlock control module is used to lock the issuing channels of the remaining connection instructions after the current connection instruction is issued, generate an interface locking instruction and output it to the explosion-proof indicator light module; the explosion-proof indicator light module is used to force the two-color LED indicator lights of the hose interface corresponding to the remaining connection instructions other than the current connection instruction to turn off according to the interface locking instruction.

[0018] Specifically, the data types recorded in the operation log generated by the upper computer simulation module include operation timestamp, on-site operator ID, hose connection path, wine delivery data, wine concentration and pipeline component sensor data; the upper computer simulation module is used to store the operation log in the database using blockchain technology, perform multi-dimensional retrieval according to the data type in the operation log, and generate an audit report for external presentation.

[0019] The present invention also provides a method for intelligent protection of hose connection based on dynamic guidance and multi-level interlocking, comprising:

[0020] S1. Receive liquor transportation task requirements, obtain a three-dimensional pipeline topology model that maps the actual pipeline structure on site, dynamically generate a hose connection logic diagram based on the three-dimensional pipeline topology model, and obtain connection instructions;

[0021] S2. Install an intrinsically safe LED light assembly at the hose interface on site, and configure the intrinsically safe LED light assembly with multiple sets of two-color LED indicator lights. The position of each set of two-color LED indicator lights corresponds to the position of each hose interface.

[0022] The S3, intrinsically safe LED light group receives connection instructions and identifies different types of hose interfaces through different indicator color codes. At the same time, the differentiated strobe patterns of each indicator light guide on-site workers in hose connection operations.

[0023] S4. After the current connection instruction is issued, the issuing channel of the remaining connection instructions is locked; after the hose interface corresponding to the current connection instruction is connected, the liquor transportation task is executed, and the operation data and status data generated before and after the connection operation are fed back, and the operation log is generated and stored.

[0024] Preferably, in step S3, the first color of the two-color LED indicator light in the intrinsically safe LED lamp group represents that the pipeline connection point corresponding to the hose interface is the pump front connection point, and the second color represents that the pipeline connection point corresponding to the hose interface is the pump rear connection point or jumper point.

[0025] Preferably, according to the received connection instruction, for the hose interface that needs to be connected to the hose, the two-color LED indicator light corresponding to the hose interface flashes at a low frequency; for the hose interface that needs to be disconnected, the two-color LED indicator light corresponding to the hose interface flashes at a high frequency; when the liquor transportation task is in progress, the two-color LED indicator light corresponding to the hose interface that has completed the connection is always on.

[0026] In summary, due to the adoption of this technical solution, the beneficial effects of the present invention are as follows:

[0027] This invention reconstructs the liquor delivery pipeline connection process through intelligent technology, significantly improving operational safety and process controllability. It employs dynamic light signal guidance technology, combining red and green color coding with differentiated strobe patterns to create a three-dimensional visual feedback system, effectively reducing the operator's cognitive load. Combined with a multi-level interlocking mechanism controlled by a PLC, this system enforces serialization of operational processes, ensuring that the pipeline system can only be activated after bidirectional verification of physical connections and digital instructions, thus eliminating the possibility of misconnection at the source. The system's built-in intrinsically safe LED lighting and IP67 protection structure ensure stable operation of the equipment under complex operating conditions while meeting safety standards for flammable and explosive environments.

[0028] After implementation, the system, through deep collaboration between the equipment and control layers, has reduced the incidence of hose connection errors by over 90%, shortened the time required for a single connection operation by 20%, and shortened the training cycle for new employees to one-fifth of the traditional model. Digital traceability throughout the entire production process combines key data such as operation timestamps, pipeline parameters, and process indicators with blockchain evidence storage technology to form an unalterable quality traceability chain. This not only allows for precise identification of the responsible node for quality incidents within 48 hours, but also establishes a data management system that complies with GMP standards and FDA audit requirements, providing reliable technical support for the intelligent upgrade of the liquor industry.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0034] Example 1

[0035] This embodiment provides a hose connection intelligent protection system based on dynamic guidance and multi-level interlocking. Figure 1 The various components of the system, their data transmission, and their working principles are shown, which can be referenced simultaneously. The system includes a host computer simulation module and a field device module that are communicatively connected. The field device module includes an explosion-proof indicator light module, an interlock control module, and an array connection guide module. A comprehensive description of each module in this embodiment is as follows:

[0036] The host computer simulation module is used to obtain the requirements of the liquor transportation task, dynamically generate a hose connection logic diagram based on the 3D pipeline topology model, obtain connection instructions, and sequentially send them to the field equipment modules. It also receives operation and status data fed back by the field equipment modules, generates and stores operation logs;

[0037] The explosion-proof indicator light module receives the light signal instructions output by the array connection guidance module and identifies different types of hose interfaces through different indicator light color codes. At the same time, the differentiated strobe patterns of each indicator light guide on-site workers in hose connection operations.

[0038] The interlock control module is used to lock the issuing channels of other connection instructions after the current connection instruction is issued and before the connection of the corresponding hose interface is confirmed, thereby locking the hose interfaces other than the hose interface corresponding to the current connection instruction;

[0039] The array connection guidance module is used to receive and parse connection instructions, generate light signal instructions and output them to the explosion-proof indicator light module to activate the corresponding indicator light; at the same time, after the hose interface is connected, its connection status is obtained, the matching of the connection status and the connection instruction is verified and feedback is provided.

[0040] This embodiment provides a detailed introduction to the above core components and their operating mechanisms.

[0041] The system's host computer simulation module establishes real-time communication with the field equipment module via Ethernet or industrial bus. The host computer has a built-in three-dimensional pipeline topology modeling engine, which can construct a digital model that fully maps the physical pipeline by importing CAD drawings or laser scanning point cloud data. The model accurately marks the spatial coordinates and logical relationships of each pipeline component, including but not limited to the direction of the pipeline, the opening and closing status of the valve, and the positioning information of the hose interface. When a wine delivery task is received, the system automatically generates the optimal connection path based on the preset fluid dynamics algorithm and task requirements, and converts the abstract task instructions into a connection instruction set that includes parameters such as interface number, operation sequence, and allowable pressure range. During the process of issuing the connection instruction, the host computer simulation module can simultaneously generate a visual connection logic diagram, and present the spatial topological relationship and operation timing constraints of the hose connection through the human-machine interface.

[0042] The explosion-proof indicator light module consists of an explosion-proof aluminum alloy shell, an intrinsically safe LED light group and related control circuits. Its protection level reaches the IP67 standard, ensuring safe operation in the liquor production environment. Figure 2 As shown in the figure, each hose interface corresponds to a set of two-color LED indicators. The two-color LED indicator can be a lamp bead that emits two colors of light, or a Figure 2In this embodiment, a red light source is used to mark the connection point before the pump, and a green light source is used to mark the connection point after the pump or the jumper point.

[0043] Each indicator light provides dynamic guidance through differentiated flashing frequencies: indicators corresponding to interfaces requiring connection flash at a low frequency of 0.5Hz to indicate the intended action, while indicators corresponding to interfaces requiring disconnection flash at a high frequency of 1Hz to indicate the intended action. The demarcation point between low and high frequencies can be selected as needed in practice to meet the guidance requirements for on-site operators. Once the hose is physically connected and verified by the pressure sensor, the corresponding indicator light turns solid. The explosion-proof indicator light module also utilizes optoelectronic isolation circuitry to ensure that signal transmission complies with electrical safety regulations for explosion-proof areas.

[0044] The interlock control module uses a redundantly designed PLC logic controller, which is connected to the on-site sensor equipment and the host computer simulation module through hard wiring. When the host computer issues the current connection instruction, the module can cut off the transmission channel of the remaining connection instructions and send an interface lock signal to the explosion-proof indicator light module through the array connection guidance module. At this time, all indicator lights except the target interface are forced to go out, forming a physical operation isolation zone to guide on-site workers. Operators must complete the connection or disconnection operation of the corresponding hose interface that is currently in the low-frequency / high-frequency flashing indicator light state according to system requirements, and the interlock state can only be released after double verification of related component detection such as pressure sensors and human-computer interaction confirmation. This mechanism ensures that the operation process strictly follows the serialization order and completes multiple sequential connection instructions issued by the host computer in sequence to prevent the risk of cross-connection of pipelines caused by cross-step operations.

[0045] The array connection guidance module integrates a signal parsing unit and a status feedback unit, and is responsible for converting the digital instructions of the host computer into lighting control signals and collecting interface connection status data in real time. After receiving the connection instruction via industrial Ethernet, the module parses the target interface coordinates and operation type, and sends them to the explosion-proof indicator light module to drive the corresponding indicator light to execute the preset strobe mode. In the process of hose plugging in this embodiment, the module can determine whether the interface connection meets the sealing requirements and whether the pipeline type and connection match the connection instruction by receiving the verification signal of the torque sensor or the near-field communication tag. If an abnormal situation such as a wrong connection or incomplete locking is detected, the host computer can trigger an audible and visual alarm and freeze the operation of subsequent system processes until manual intervention is completed to troubleshoot the problem.

[0046] In this embodiment, the operation log generated by the system after feedback utilizes blockchain distributed storage technology. Each operation record is automatically appended with a timestamp, operator ID, and digital certificates of the relevant equipment components, forming an unalterable data block. The operation log also preferably includes diverse information such as fluid parameter curves for the hose connection path corresponding to the connection instruction, liquor concentration data, and pipeline vibration spectra. Audit reports are generated by clustering and analyzing massive amounts of operation data using a relational database, rapidly locating abnormal operation nodes and reconstructing incident timelines, thereby complying with stringent process traceability requirements such as those required by GMP.

[0047] Example 2

[0048] Based on Example 1, this example introduces a hose connection intelligent protection method based on dynamic guidance and multi-level interlocking, which can be seen in Figure 3 The hardware basis of this method is the hose connection intelligent protection system described in Example 1. This method can be smoothly run in each functional module of the system. The steps are summarized as follows:

[0049] S1. Receive liquor transportation task requirements, obtain a three-dimensional pipeline topology model that maps the actual pipeline structure on site, dynamically generate a hose connection logic diagram based on the three-dimensional pipeline topology model, and obtain connection instructions;

[0050] S2. Install an intrinsically safe LED light assembly at the hose interface on site, and configure the intrinsically safe LED light assembly with multiple sets of two-color LED indicator lights. The position of each set of two-color LED indicator lights corresponds to the position of each hose interface.

[0051] The S3, intrinsically safe LED light group receives connection instructions and identifies different types of hose interfaces through different indicator color codes. At the same time, the differentiated strobe patterns of each indicator light guide on-site workers in hose connection operations.

[0052] S4. After the current connection instruction is issued, the issuing channel of the remaining connection instructions is locked; after the hose interface corresponding to the current connection instruction is connected, the liquor transportation task is executed, and the operation data and status data generated before and after the connection operation are fed back, and the operation log is generated and stored.

[0053] In step S3 of this embodiment, the first color (for example, red) of the two-color LED indicator light in the intrinsically safe LED lamp group represents that the corresponding pipeline connection point of the hose interface is the front connection point of the pump, and the second color (for example, green) is used to represent that the corresponding pipeline connection point of the hose interface is the rear connection point of the pump or the jumper point.

[0054] In this embodiment, according to the received connection instruction, for the hose interface that needs to be connected to the hose, the two-color LED indicator light corresponding to the hose interface is made to flash at a low frequency of 0.5Hz; for the hose interface that needs to be disconnected, the two-color LED indicator light corresponding to the hose interface is made to flash at a high frequency of 1Hz; when the liquor transportation task is in progress, the two-color LED indicator light corresponding to the hose interface that has completed the connection is always on.

[0055] In this embodiment, step S4 serves as the interlocking execution stage when the method is implemented. Its core lies in that only one connection task is allowed to be activated during a single operation, and the interface indicator lights that do not correspond to this connection instruction are forced to go out. After the on-site operator completes the connection between the hose and the hose interface each time, the on-site operator needs to manually open the manual valve at the connection end, and then interact with the host computer for confirmation. At this time, if the system monitoring is normal, it will open the electric valve related to the corresponding wine transportation and start the wine pump based on the currently selected and connected link; after the wine pump is started, the system can determine the execution of the task based on its instantaneous pressure, flow and other sensor verification data, and start the wine transportation. If the feedback obtained by the system is a hose connection error when the hose is connected, a fault alarm and a text prompt on the human-computer interaction interface will be triggered, and the relevant electric valves and wine pumps will be automatically closed by the system until manual intervention is completed to troubleshoot the problem.
