It should be understood that the present invention is not limited to the example embodiments used only to explain the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all of them.
[0042] Example
[0043] Figure 1 The present invention is a schematic structural diagram of a quick-opening pressure vessel control system, wherein the system comprises:
[0044] The initialization configuration module 11 is used to obtain the target pressure vessel, install and configure the system functional components.
[0045] Specifically, the system functional components refer to multiple functional components used to control the target pressure vessel, which are installed in corresponding positions and adaptively configured based on the characteristic parameters of the target pressure vessel. The characteristic parameters of the target pressure vessel include external dimensions, material type, design scenario, and performance parameters (working pressure, capacity, etc.).
[0046] Specifically, based on the characteristic parameters of the target pressure vessel, functional components with appropriate ranges and working parameters are selected to achieve effective control and monitoring of the target pressure vessel.
[0047] In some embodiments, the system functional components include at least a biometric component, a limit switch, a solenoid valve, a pressure sensor, a temperature sensor, and a PLC control component.
[0048] Specifically, the system functional components installed and configured in the target pressure vessel include: biometric components used for user identity authentication to ensure the safety and traceability of system operations. In actual use, as a special equipment, the quick-opening pressure vessel needs to be controlled by operators with professional skills and qualifications. Therefore, the target pressure vessel is equipped with a biometric component to collect the user's biometric features, such as fingerprints, faces, irises, etc., and match them with the biometric features stored in the corresponding operator database, thereby ensuring that the operation to be performed is issued by a user with corresponding qualifications.
[0049] Specifically, the solenoid valve is installed on the medium inlet and outlet channel of the target pressure vessel, and is connected to the PLC control component for communication, receiving control signals, and controlling the flow of the medium fluid. The solenoid valve includes a steam inlet pipe solenoid valve installed on the medium charging channel and a steam exhaust pipe solenoid valve installed on the medium exhaust channel. The specific model of the solenoid valve is determined according to the type and flow of the medium handled by the target pressure vessel.
[0050] Specifically, the limit switch is used to control and sense the position of the target pressure vessel's quick-open door to prevent it from exceeding a preset position. The limit switch is connected to the PLC control component for communication, receives control instructions from the PLC control component, and feeds back position status information of the target pressure vessel's quick-open door. Exemplarily, the limit switch includes a mechanical limit switch and a photoelectric sensor switch.
[0051] Specifically, the pressure sensor includes a resistive pressure sensor, a capacitive pressure sensor, etc. It is used to monitor the real-time pressure condition inside the target pressure vessel, and is connected to the PLC control component to transmit pressure data to realize pressure feedback control. The temperature sensor is used to monitor the operating temperature of the target pressure vessel (including internal temperature, wall temperature, ambient temperature, etc.), and the temperature sensor is connected to the PLC control component to transmit temperature data.
[0052] Specifically, the PLC control component is a programmable logic controller, which is the central controller of the system functional components and is used to coordinate and manage the operation of each functional component. The PLC control component has multiple input and output interfaces, which are connected to the biometric component, limit switch, solenoid valve, pressure sensor, temperature sensor, etc. By configuring the programmable PLC control component, the adaptability and portability of the control system of the present invention to different scenarios are improved.
[0053] The control strategy configuration module 12 is used to formulate a control strategy based on the initialization result and the characteristic parameters of the target pressure vessel in combination with the target scenario requirements, wherein the control strategy at least includes associated control limits, emergency measures, action flow and timing.
[0054] Specifically, the initialization result refers to the system functional components configured for the target pressure vessel, including the composition, location, applicable scope, control accuracy, etc. of the system functional components. The characteristic parameters of the target pressure vessel refer to the physical and chemical performance parameters of the target pressure vessel body, including, for example, the vessel type, vessel material, maximum working pressure, working temperature range, internal volume, etc.
[0055] Optionally, the control strategy includes associated control limits, emergency measures, action flow and timing, etc., where the control limit is the range of operating parameters that meet the characteristic parameters of the target pressure vessel and the constraints of the initialization results, mainly including pressure control limits and temperature control limits. Emergency measures specify the methods and measures for handling risk events under specific working conditions. Exemplarily, emergency measures include overpressure emergency measures, overtemperature emergency measures, sensor failure emergency measures, etc. The emergency measures are determined according to the emergency management plan of the target scenario or the emergency management rules in related fields. The action flow and timing specify the operation process, steps and time node arrangements of the steps under various working conditions. Through the above control strategy, the system is ensured to operate in a safe, stable and efficient state, while having the ability to respond quickly to abnormal situations.
[0056] In some embodiments, Figure 2 As shown, based on the initialization results and the characteristic parameters of the target pressure vessel, combined with the target scenario requirements, a control strategy is formulated, and the execution steps include:
[0057] Based on the initialization result and the characteristic parameter, a control limit of the target pressure vessel is determined.
[0058] A reachability analysis of the target scenario requirements is performed according to the control limits, wherein the target scenario requirements include medium requirements, performance requirements, and environmental requirements.
[0059] Based on the reachability analysis results, multiple control instruction groups corresponding to the target scenario requirements are configured and stored as the control strategy, wherein the control instruction group includes associated stored control limits, action flow and timing, and emergency measures.
[0060] Specifically, firstly, the initialization result and the characteristic parameters are integrated to calculate and determine the control limits of the target pressure vessel, wherein the control limits of the target pressure vessel include pressure limit, temperature limit, accuracy limit, capacity limit, etc.
[0061] Then, clarify the target scenario requirements, including medium requirements (such as medium type and quantity), performance requirements (such as flow rate, pressure, temperature resistance requirements), and environmental requirements (such as working ambient temperature, humidity, etc.). Then, compare the target scenario requirements with the control limits of the above-mentioned target pressure vessel to determine whether the target scenario requirements are within the control limits and perform a reachability analysis. If multiple requirements in the target scenario requirements are true subsets of the control limits, the reachability of the target scenario requirements can be considered true. Through reachability analysis, ensure that all requirements of the target scenario can be met within the control limits.
[0062] Specifically, according to the reachability analysis results, multiple control instruction groups are configured, including converting the target scenario requirements with true reachability into multiple control instruction groups that can be understood by the target pressure vessel through the corresponding PLC control language. Optionally, the above conversion is performed through control languages such as Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), etc.
[0063] Exemplarily, multiple control instruction groups corresponding to target scenario requirements are configured, including converting the solenoid valve flow requirements in the target scenario requirements into instructions for adjusting the solenoid valve opening to ensure that the pressure does not exceed the set pressure limit, and determining the triggering conditions and execution logic of each control instruction group. For example, when the pressure exceeds the warning pressure, the pressure relief instruction is triggered to open the solenoid valve to a preset opening.
[0064] Specifically, after obtaining multiple control instruction groups, all configured control instruction groups are stored in the PLC control component to ensure the rapid call of the instructions. The above steps ensure that the system can operate efficiently within a safe range by determining the control limits and detailed reachability analysis. By configuring detailed control instruction groups and storing them in the PLC control component, accurate control and rapid response of the target pressure vessel can be achieved.
[0065] The user authentication module 13 is used to interact with the user end, obtain the user's biometric authentication information for compliance authentication, and release the safety lock of the target pressure vessel based on the compliance authentication result.
[0066] Specifically, the user end is the hardware and program used to interact with operators or users. For example, the user end includes biometric components, display devices, input devices, communication devices, alarm devices, etc. Among them, the biometric components include fingerprint recognition devices, facial recognition cameras, iris recognition devices, etc., which are used to obtain the user's biometric authentication information; the display device is used to display the authentication process and results; the input device is used to accept the user's operation input; the communication device is used to interact with the database, information management platform or server that stores the user's authentication information to ensure the real-time transmission and verification of the authentication information; the alarm device is used to issue an alarm in the event of authentication failure or abnormality to ensure system security.
[0067] Specifically, through data encryption, the collected biometric authentication information is compared and analyzed with the user authentication stored in the database, information management platform or server to perform compliance authentication. Exemplary methods include verifying user identity, checking user permissions, and providing feedback on authentication results.
[0068] Specifically, if the user's biometric authentication information passes the compliance authentication, the user end will feedback the safety lock release instruction to the PLC control component, and execute the safety lock release operation through the PLC control component to allow the target pressure vessel to be operated. On the contrary, if the authentication fails, the user end will issue a non-compliance alarm through the alarm device, and display the authentication failure information on the display device, and record the detailed information of the authentication failure. Furthermore, after multiple authentication failures, security protection measures are initiated, such as locking the system or sounding an alarm, to ensure system safety.
[0069] The above steps, through biometric authentication and data encryption, ensure that only legitimate users who have passed compliance authentication can unlock the safety lock of the pressure vessel and perform pressure vessel operations, thereby achieving safe and effective management of the target pressure vessel.
[0070] The status update module 14 is used to collect user operation instructions through the user terminal, and call the system function components to perform monitoring and collection based on the user operation instructions to obtain key identification indicator data of the target pressure vessel.
[0071] Specifically, first, the user end collects user operation instructions, such as "start monitoring", "obtain data", etc. Then, the instruction parsing module parses the instructions input by the user, identifies the instruction type and parameters, and transmits the parsed operation instructions to the control module through the communication module. After receiving the operation instruction, the control module parses the instruction content, determines the system function components that need to be called, and calls the corresponding system function components, such as starting the temperature sensor, pressure sensor, etc., to start monitoring and data collection, obtain the real-time status information of the target pressure vessel, and store it as key discrimination indicator data.
[0072] Specifically, the key discriminating indicator data reflects the real-time status information of the target pressure vessel, and is used to determine whether the target pressure vessel has the ability and status to execute the user's operating instructions. For example, the operating instructions of a specific medium have strict requirements on the wall temperature of the target pressure vessel. Too high or too low wall temperature will affect the physical and chemical properties of the medium, and further affect safety and efficiency. At this time, the key discriminating indicator data is the wall temperature of the target pressure vessel.
[0073] The above steps provide accurate real-time status data through real-time monitoring, analyze key judgment indicator data, provide decision support for operators and control systems, and help to timely discover and warn of potential safety hazards, avoid user misoperation, and ensure that pressure vessels operate within a safe range.
[0074] In some embodiments, the user terminal collects user operation instructions, and based on the user operation instructions, the system function component is called to perform monitoring and collection to obtain key identification indicator data of the target pressure vessel, and the execution steps include:
[0075] The target discrimination index set is called with the user operation instruction as a calling constraint.
[0076] Based on the data dimension reduction method, the target discrimination index set is parsed to obtain the target index sequence, and the first N discrimination indexes are extracted to generate the target key discrimination index set.
[0077] The system function components are called according to the target key discriminant indicator set to perform monitoring and collection to obtain the key discriminant indicator data.
[0078] Specifically, the target discrimination index set is obtained based on the preset calling relationship and the user operation instruction is used as the calling constraint, wherein the target discrimination index set includes all the index categories related to the safety and operation efficiency of the user operation instruction, such as container pressure, container temperature, medium temperature, limit switch position status, ambient temperature, vibration level, etc. The preset calling relationship is determined by obtaining common operation modes and calling relationships through relevant expert systems, knowledge graphs or analyzing historical operation records.
[0079] Furthermore, based on data dimensionality reduction methods such as principal component analysis (PCA), linear discriminant analysis (LDA) or t-SNE, the target discriminant indicator set is analyzed to simplify the data dimension, highlight the key features, obtain the target discriminant indicator sequence, and extract the top N discriminant indicators according to their influence or importance to generate the target key discriminant indicator set.
[0080] Exemplarily, the target key discrimination index set includes all discrimination indexes related to the safety of the target pressure vessel and some discrimination indexes highly correlated with the efficiency of the target pressure vessel.
[0081] Through the above steps and technical means, efficient acquisition and processing of key identification index data of target pressure vessels are achieved, providing a high-quality decision-making basis for the safe monitoring and control of pressure vessels.
[0082] The decision control module 15 is used to make a judgment decision on the key judgment indicator data according to the control strategy, output a pressure vessel response instruction, and perform a control operation on the target pressure vessel according to the pressure vessel response instruction.
[0083] In some embodiments, according to the control strategy, a judgment decision is made on the key judgment indicator data, and a pressure vessel response instruction is output, and the execution steps include:
[0084] According to the user operation instruction, the control strategy is traversed and matched to obtain a target control instruction group.
[0085] The key discriminant indicator data is compared with the target control limit, wherein the target control limit is the control limit in the target control instruction group.
[0086] If the key discrimination indicator data meets the target control limit, the corresponding control process and timing, and emergency plan are stored as the pressure vessel response instruction.
[0087] Specifically, the key discriminant indicator data is judged and decided. First, the aforementioned control strategy is called through the PLC control component to match and obtain the control instruction group corresponding to the user operation instruction, that is, the target control instruction group. Then, the key discriminant indicator data is compared with the target control limit in the target control instruction group to determine whether the control conditions are met. If all are met, the corresponding control process and timing, and emergency plan are stored.
[0088] Specifically, if any item in the key discrimination indicator data does not meet the target control limit, the current state of the target pressure vessel may be unable to complete the user operation instruction, and an invalid operation result is returned to the user end, wherein the invalid operation result includes the specific control limit that is not met, the current indicator data, and possible reasons and suggestions.
[0089] For example, if the user's operation instruction is to increase the internal pressure of the pressure vessel, but the current temperature is too high and exceeds the safety control limit. After comparing the key identification indicator data (temperature, pressure, etc.) with the target control limit, the system finds that the temperature does not meet the control limit, determines that the operation instruction to increase the pressure cannot be executed, and returns an invalid operation result to the user end, prompting the user that the current temperature is too high, and recommends lowering the temperature before trying to increase the pressure.
[0090] Through the above steps, it is effectively determined whether the pressure vessel can complete the user's operation instructions in the current state, and outputs safe and achievable pressure vessel response instructions. When the key discrimination indicator data does not meet the target control limit, the invalid operation result is returned to the user end in time, avoiding the risks and safety hazards caused by blind operation. The automation level of pressure vessel control is improved, the impact of human error operation is reduced, and the safe and efficient operation of pressure vessels is ensured.
[0091] In some embodiments, the control operation on the target pressure vessel is performed according to the pressure vessel response instruction, and the execution steps include:
[0092] The pressure vessel response instruction is transmitted to the PLC control component.
[0093] If the pressure vessel response instruction is a start instruction, the limit switch is closed to the first preset position, and ensure that the quick opening door of the target pressure vessel is well closed, close the exhaust pipe solenoid valve, open the steam inlet pipe solenoid valve, and allow the medium to enter the target pressure vessel until the pressure in the target pressure vessel rises to the working pressure.
[0094] If the pressure vessel response instruction is an end instruction, the exhaust pipe solenoid valve is closed and the steam inlet pipe solenoid valve is opened until the pressure in the target pressure vessel drops to the standard pressure, the limit switch is opened to the second preset position, and the quick opening door of the target pressure vessel is opened.
[0095] Specifically, industrial communication protocols such as Modbus and Profibus are used to transmit pressure vessel response instructions to the PLC control component to control the target pressure vessel, including the determination of the limit switch position status information, and the limit switch includes a first preset position and a second preset position. Among them, the first preset position is the position of the limit switch when the quick-opening door of the target pressure vessel is well closed, which is used to check and confirm that the quick-opening door of the pressure vessel is completely closed and locked well to avoid safety risks such as medium leakage or accidental opening. The second preset position is the position of the limit switch when the quick-opening door of the target pressure vessel needs to be opened. When the pressure value in the target pressure vessel drops to a safe standard pressure, the PLC control component is used to unlock and move the limit switch to the second preset position, allowing the quick-opening door of the pressure vessel to be opened to take out or add materials.
[0096] The above steps ensure that the pressure vessel is in a safe state during operation through multiple confirmations of limit switches and corresponding sensors, avoiding safety risks caused by human errors.
[0097] In some implementations, before calling the system function component to perform monitoring and collection based on the user operation instruction to obtain key identification indicator data of the target pressure vessel, the execution step further includes:
[0098] Collect the control records of the target pressure vessel and determine the instruction space in combination with the design data of the target pressure vessel.
[0099] Based on the pressure vessel knowledge graph and the control records, an association analysis is performed to establish an association relationship set between the instruction space and the discrimination index.
[0100] Specifically, the target scenario is interacted with to obtain the control record of the target pressure vessel, which reflects all the operation instructions involved in the target pressure vessel in the application scenario or application field. Among them, the control record includes operation logs, maintenance records, fault records, etc. Then, the collected control records are compared and analyzed with the design data of the target pressure vessel (such as operation manuals, technical specifications, design drawings, etc.) to determine the executable instruction set, that is, the instruction space.
[0101] Specifically, the control records are analyzed through the pressure vessel knowledge graph to discover potential associations and patterns and obtain an association relationship set, wherein the pressure vessel knowledge graph contains knowledge such as the structure, operation principle, common faults and their treatment methods of pressure vessels. By analyzing the pressure vessel knowledge graph, the association relationship set of multiple instructions and discrimination indicators in the instruction space is determined according to the relationship edges between the instruction subject and the discrimination indicator subject. The association relationship set is the common association relationship during pressure vessel control.
[0102] Furthermore, based on the association analysis method, an association analysis is performed on the control records and various discrimination indicators of the target pressure vessel to determine the association relationship set between the various instructions in the control records and the discrimination indicators. The association relationship set reflects the specific association relationship of the target pressure vessel under the target scenario.
[0103] Furthermore, the two association relationship sets based on the pressure vessel knowledge graph and the control record acquisition are combined to generate an association relationship set of the instruction space and the discrimination index. Specifically, it includes retaining the consistent relationship in the two association relationship sets and retaining the part of the difference relationship part that belongs to the specific association relationship.
[0104] Through the above steps, the common part and specific part of the association relationship are obtained based on the pressure vessel knowledge graph and control records respectively, and the association relationship set of the instruction space and the discrimination index is generated by merging, which helps to improve the accuracy and depth of control decisions, and thus improve the reliability of pressure vessel control.
[0105] Further, the control operation on the target pressure vessel is performed according to the pressure vessel response instruction, and then the execution step of the system further includes:
[0106] The system functional component is called to continuously monitor the target pressure vessel to obtain real-time pressure data and real-time temperature data.
[0107] Based on the real-time pressure data and the real-time temperature data, a control deviation is calculated, and a control deviation warning is issued.
[0108] The control deviation, the real-time pressure data and the real-time temperature data are combined to perform safety warning and safety response of the target pressure vessel.
[0109] Specifically, the target pressure vessel is continuously monitored through the pressure sensors and temperature sensors in the system functional components to obtain pressure and temperature data in real time. Then, based on the real-time pressure and temperature data, the data processing and analysis algorithm is used to calculate the degree of deviation between the current operating state and the preset standard (control deviation), and an early warning is issued when the deviation exceeds the preset threshold. The early warning is carried out through methods including sound and light alarms, text messages or email notifications.
[0110] Optionally, after comprehensively considering the control deviation, real-time pressure data and real-time temperature data, after the safety warning of the target pressure vessel, it also includes taking safety response measures when necessary, such as automatic shutdown, pressure relief, etc. Among them, the safety response measures are automatically executed through the PLC control component, and redundant design and fail-safe mechanisms (such as dual sensors and backup control systems) are used to improve control reliability.
[0111] Furthermore, a control operation on the target pressure vessel is performed according to the pressure vessel response instruction, and then the pressure vessel response instruction and the control operation signal are transmitted synchronously to the safety supervision cloud platform.
[0112] Specifically, the Industrial Internet of Things (IIoT) technology is used to synchronously transmit the executed pressure vessel response instructions and control operation signals to the safety supervision cloud platform through wireless communication (such as 4G / 5G, LoRa, etc.) or wired communication (such as Ethernet, optical fiber, etc.) for remote monitoring and management. Among them, the safety supervision cloud platform is a platform based on cloud computing technology, which is used to centrally monitor and manage the operating status and safety information of industrial equipment.
