Description

Technical Field

[0001] This invention relates to the field of industrial automation control technology, specifically a remote intelligent valve control system. Background Technology

[0002] In industries such as petroleum, chemical, water supply, and gas, valves are key control components in fluid transport systems, and the accuracy, reliability, and timeliness of their operation are of paramount importance. Traditional valve control often relies on manual on-site operation or simple wired electrical control, which suffers from problems such as low efficiency, slow response, high labor costs, and difficulty in implementation in harsh or remote environments.

[0003] With the development of IoT technology, some remote valve control systems using wireless communication have emerged. However, these systems still have significant drawbacks. First, communication security is generally insufficient, often relying on simple password authentication and transmitting data in plaintext, making them highly vulnerable to attacks and tampering, failing to meet the high security requirements of industrial control systems. Second, system scalability is poor; existing architectures struggle to support unified management of large-scale, distributed valve clusters, and adding new equipment involves cumbersome processes. Third, existing terminal equipment lacks environmental adaptability, exhibiting weak waterproof and corrosion resistance, making it difficult to operate stably in harsh environments such as humid conditions and large temperature fluctuations. Finally, the systems lack intelligent analysis capabilities, failing to deeply mine and analyze historical operating data and valve status to achieve predictive maintenance and optimized control.

[0004] Therefore, there is an urgent need in this field for a remote intelligent valve control system that integrates high-strength security encryption, flexible network topology, powerful scalability, strong environmental robustness, and intelligent analysis capabilities. Summary of the Invention

[0005] The purpose of this invention is to provide a remote intelligent valve control system, which achieves remote, intelligent, highly secure, and highly scalable valve control through a collaborative architecture of system host, intelligent gateway, execution terminal and cloud, combined with encrypted communication based on digital certificates.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A remote intelligent valve control system includes: The system host (XPSys-A2024) provides a human-machine interface and performs functions such as device monitoring, device group management, project management, operation log recording, and intelligent analysis. At least one smart gateway (XPLink-A01) is communicatively connected to the system host and is used to receive control commands from the system host and perform protocol conversion and data pass-through. The smart gateway supports remote wireless communication via 3G / 4G mobile communication networks. Multiple remote intelligent execution terminals (XP-A00110) are communicatively connected to the intelligent gateway to receive control commands converted by the intelligent gateway and drive the valve to perform opening, closing or adjustment operations based on the commands. At the same time, they collect the real-time status information of the valve and feed it back to the system host through the intelligent gateway. And a cloud server, which is communicatively connected to the system host, for receiving and storing data from the system host and providing a remote access interface; The communication connections between the smart gateway and the remote smart execution terminal, as well as between the system host and the cloud server, are all encrypted and authenticated using key pairs based on CA digital certificates.

[0007] Preferably, the system host includes an Intel Pentium or Core series processor, 4GB or more of DDR4 memory, 128GB or more of SSD hard drive, dual gigabit network cards, and runs a Windows or Linux operating system.

[0009] Preferably, the system supports system expansion by increasing the number of smart gateways, with a maximum management capacity of 100 smart gateways, thereby supporting the management of up to 10,000 remote intelligent execution terminals.

[0010] Preferably, the remote intelligent execution terminal is an integrated valve controller structure with IPX7 waterproof rating and is equipped with a valve status feedback device for real-time monitoring of the valve's opening degree, closing status, or fault status.

[0011] Preferably, the remote intelligent execution terminal is also equipped with an external sensor interface for connecting at least one of an air temperature and humidity sensor or a soil temperature and humidity sensor to collect environmental parameter data.

[0012] Preferably, the communication modulation method between the smart gateway and the remote smart execution terminal is the Modbus protocol.

[0013] A communication encryption method based on the aforementioned remote intelligent valve control system includes the following steps: The system assigns a unique key pair and CA digital certificate to newly connected smart gateways or remote smart execution terminal devices; When a device attempts to connect to the system, the system requests the device to present its CA digital certificate. The system verifies the validity and authenticity of the CA digital certificate; Once the verification is successful, an encrypted communication channel is established based on the device's public key, and all subsequent data transmissions are encrypted through this channel.

[0014] A method for expanding equipment capacity based on the aforementioned remote intelligent valve control system includes the following steps: The system host detected that the number of remote intelligent execution terminals requiring additional management exceeded the capacity of the existing intelligent gateway; Add a new smart gateway to the system network; The system host configures and authenticates the newly added smart gateway with a CA certificate, and incorporates it into the management system; Connect and authenticate the newly deployed remote intelligent execution terminal with the newly added intelligent gateway; The system host updates its device management list to include the newly added smart gateway and its subordinate remote intelligent execution terminals within the management scope, thereby expanding the system capacity.

[0015] A valve management method based on the aforementioned remote intelligent valve control system includes the following steps: The system host receives valve control commands issued by the user through the human-machine interface or remote client; The system host sends the control commands to the smart gateway connected to the target remote intelligent execution terminal via an encrypted communication channel; The smart gateway performs protocol conversion on the received instructions and sends the converted instructions to the target remote smart execution terminal through the local network. The remote intelligent execution terminal executes the instructions to drive the valve to move and collects the valve's status data; The remote intelligent execution terminal returns the status data to the system host via the intelligent gateway and the encrypted communication channel; The system host records the operation log and updates the status display of the corresponding valve in the graphical interface.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) The key pair authentication mechanism based on CA digital certificates is adopted to ensure the legitimacy of device access and the confidentiality and integrity of data transmission, effectively resisting man-in-the-middle attacks and data tampering, and meeting the high security standards of industrial control systems.

[0017] 2) Through intelligent gateway cascading and enhanced host management capabilities, the system can be smoothly expanded from a small network to a large-scale network, adapting to the needs of projects of different sizes, reducing initial investment costs and the difficulty of later expansion.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example: The present invention provides a remote intelligent valve control system, which mainly consists of four layers: cloud service layer, host control layer, gateway communication layer and terminal execution layer.

[0025] The system host is the core management unit and brain of the entire system. Its hardware configuration is a high-performance industrial-grade computer to ensure system stability and the ability to process large amounts of data. The specific configuration is as follows: The processor uses an Intel Pentium series or Core i3 / i5 / i7 series processor. These processors have powerful computing capabilities and can handle multi-threaded tasks simultaneously, such as real-time data acquisition, graphical interface rendering, communication data processing, and background intelligent analysis algorithm execution.

[0026] It comes standard with 4GB of DDR4 memory, with optional 8GB or 16GB. The large memory capacity ensures that the system will not experience performance bottlenecks when simultaneously monitoring a large number of valve terminals, running complex analysis programs, and processing historical log data.

[0027] It comes standard with a 128GB solid-state drive (SSD), with optional 256GB, 512GB, or 1TB SSDs. The high-speed read and write capabilities of the SSD greatly improve system boot speed, application loading speed, and data access speed. In addition, the host also has reserved additional hard drive expansion slots, which can accommodate two 2.5-inch or one 3.5-inch hard disk drives for long-term storage of massive operation logs, project data, and status history records.

[0028] The motherboard integrates two Gigabit Ethernet cards, providing high-speed and stable wired network connectivity. An optional built-in wireless network card module is available, increasing network connectivity flexibility.

[0029] It integrates Intel HD Graphics or a dedicated graphics card and provides VGA and DVI video output interfaces, allowing connection to various monitors.

[0030] It adopts a wide voltage input power supply (AC 100V-240V, 50 / 60Hz) to adapt to different power grid standards worldwide. The chassis is made of Maanshan Iron & Steel's high-grade galvanized steel sheet with a powder-coated black sandblasted finish, making it sturdy, durable, and with excellent heat dissipation.

[0031] The front panel interfaces include a power switch, a reset button, and two USB 2.0 ports for easy daily operation and maintenance. The rear panel interfaces include a PS / 2 port, two USB 2.0 ports, two COM serial ports for connecting traditional industrial equipment, audio input / output, VGA, DVI, two USB 3.0 high-speed ports, a power connector, and a PCIe half-height expansion card slot for expanding with dedicated communication cards. This rich array of interfaces allows for seamless integration into various existing industrial environments.

[0032] In terms of operating system and software, it can install operating systems such as Windows 7, Windows 10, Linux, or Windows Server. Dedicated management software for this system runs on it, and this software implements the following core functional modules: The equipment monitoring module provides a graphical human-machine interface, displaying the real-time status of all valve terminals in the form of lists, topology diagrams, or map points. Users can directly send commands to select valves to open, close, or adjust their opening degree by clicking on interface elements.

[0033] The equipment management module allows users to group valves based on process flow, geographical region, or other logic. A unified control command can be issued to the entire group simultaneously, greatly improving the efficiency of batch operations.

[0034] The project management module provides functions for creating, editing, and archiving projects. Each project can independently manage all devices and configurations under it, facilitating the isolated management of systems for different clients.

[0035] The operation log module records all user operations in detail, including the operator, time, object of operation, instruction content, system events, and valve status changes. All logs are timestamped and cannot be tampered with, providing a basis for accident tracing and liability determination.

[0036] The intelligent analysis module, based on operation logs and historical status data, can run analysis algorithms to reproduce the operating status curve of any valve in any historical time period, analyze the valve's action frequency, predict potential faults, and generate maintenance reports.

[0037] The system template library includes built-in control templates for different types of valves, such as ball valves, butterfly valves, and regulating valves. When adding new devices, users only need to select the corresponding template to automatically complete most parameter configurations, simplifying deployment and meeting personalized needs.

[0038] As a communication hub connecting the upstream and downstream, the smart gateway is responsible for sending instructions from the system host to the execution terminal and aggregating and uploading terminal data.

[0039] The core of the smart gateway's network communication is its built-in 4G communication module, which is compatible with 3G networks and supports China's 4G frequency bands. The 4G network provides high bandwidth, low latency, and high stability data transmission over a wide area, ensuring the real-time nature of control commands and the continuity of status data, overcoming the difficulties of deploying wired networks in remote areas.

[0040] The intelligent gateway features protocol conversion capabilities. It typically communicates with the system host using proprietary or general-purpose protocols based on TCP / IP. However, it communicates with lower-level remote intelligent execution terminals using widely used industrial protocols such as Modbus RTU or Modbus TCP. This design enables the system to efficiently and reliably manage industrial equipment that supports the Modbus protocol.

[0041] A single smart gateway possesses robust local networking capabilities, managing up to 100 endpoints. It supports various network topologies: A star network connects all endpoints directly to the gateway. It has a simple structure and low latency, but requires a large number of gateway ports.

[0042] In a ring / chain network, the execution terminals are connected in series, with the first and last terminals ultimately connected to the gateway. This saves on cabling, but the reliability is slightly lower.

[0043] Tree-based networks, combining star and chain topologies, are suitable for hierarchical management.

[0044] Mesh networks allow terminals to relay to each other, offering the highest reliability and strong self-healing capabilities.

[0045] Users can flexibly choose the most suitable topology based on the physical layout and reliability requirements of the field equipment.

[0046] The smart gateway operates on 110-240VAC with a maximum power consumption of only 10W, making it energy-efficient and environmentally friendly. Its operating temperature range is -40℃ to +70℃, sufficient to withstand harsh outdoor environments. Wired connection is achieved via a standard RJ45 interface.

[0047] The actuator is directly mounted on the valve and is responsible for final execution and status sensing. It features an integrated design, combining the valve controller, drive unit, and communication module within a single housing, employing a standardized design. This design reduces external wiring, lowers the failure rate, and simplifies field installation, requiring only mechanical connections and power supply.

[0048] The core functions are as follows: With a built-in motor drive circuit, it can receive Modbus commands from the gateway to precisely control the opening, closing, and adjustment of valves, thereby enabling control of pipeline flow, shut-off, and flow rate.

[0049] High-precision sensors are integrated as valve status feedback devices to monitor the valve's actual position, torque information, and whether a fault has occurred in real time, and upload this status data in real time.

[0050] The actuator terminal provides additional sensor interfaces, allowing connection to external air temperature and humidity sensors, soil temperature and humidity sensors, pressure sensors, etc., thereby upgrading a simple valve control system into a comprehensive environmental monitoring system. Its housing is immersion-proof, with an IPX7 protection rating, meaning that it will not leak water when immersed in water under specified time and pressure. Combined with corrosion-resistant materials and processes, it can operate stably for extended periods in extremely humid and corrosive environments such as underground mines, tunnels, and coastal areas. The operating temperature range is also -40℃ to +70℃. The operating voltage is 110-240VAC, and it communicates with the smart gateway via a 4G network.

[0051] The cloud server, as an optional remote management layer, is deployed on a public or private cloud. The system host establishes a secure, encrypted connection with the cloud service via the internet, periodically synchronizing data such as device status and operation logs to the cloud. The cloud provides a web service interface or an app interface, allowing authorized users to log in to the cloud platform from anywhere in the world via the internet to view system status, receive alarm information, and even send control commands under authorization. This achieves true unattended operation and remote maintenance.

[0052] A communication encryption method based on a remote intelligent valve control system includes the following steps: Pre-configuration: Before the smart gateway or execution terminal device leaves the factory or during its initial network access, the certificate authority at the system center generates a pair of asymmetric keys (public key and private key) and a CA digital certificate containing its public key and device identification information. The private key is securely stored in the device's hardware security module or secure storage area, while the certificate is stored in the device's ordinary storage area.

[0053] Connection request: When the device powers on and attempts to connect to the system, it first sends a connection request to the system host or gateway for the execution terminal.

[0054] Certificate Challenge: The receiving device sends a "certificate request" message.

[0055] Certificate presentation: Request the device to send its CA digital certificate to the verifier.

[0056] Certificate Verification: The verifier uses a pre-stored, trusted root CA certificate to verify the digital signature of the received device certificate. Verification includes: whether the certificate was issued by a trusted CA, whether the certificate is valid, and whether the certificate has been revoked.

[0057] Establishing a secure channel: After successful verification, the authenticating party encrypts a random session key using the public key in its device certificate and sends it to the requesting device. The requesting device decrypts the session key using its own private key. Thereafter, all communication data between the two parties is transmitted using this session key with symmetric encryption, ensuring efficient and confidential communication.

[0058] This process ensures "one device, one certificate," preventing unauthorized devices from impersonating and accessing the network, effectively preventing unauthorized access and cyberattacks.

[0059] A method for expanding equipment capacity based on a remote intelligent valve control system, wherein when the number of valves to be managed increases, the system smoothly expands according to the following process: Capacity assessment: The system administrator checks the current gateway load on the system host software. When it is found that the existing gateway's idle capacity is insufficient to connect a new batch of execution terminals, a decision is made to expand capacity.

[0060] Add gateway hardware: Purchase and physically install new smart gateway devices and connect them to power and network.

[0061] Gateway network access authentication: After the new gateway starts up, it will automatically execute the encryption authentication process described in Part 5 above to establish a secure connection with the system host. The administrator will find the new gateway in the host's device management interface, assign it a logical ID and description information, and officially integrate it into the management system.

[0062] Terminal networking and authentication: The newly deployed remote intelligent actuators are physically installed on the valves and connected to a local network via wired or wireless means, depending on the selected topology. Each actuator also needs to complete a two-way CA certificate authentication process with the gateway.

[0063] System Update: After successful authentication, the new gateway will report a list of all new terminals under its control to the system host. The system host automatically updates its global device database and graphical interface, bringing the new devices into the monitoring and management scope. At this point, the system expansion is complete. The entire process requires no changes to the existing network structure and has zero impact on the operation of the original system.

[0064] A valve management method based on a remote intelligent valve control system includes the following steps: Command Initiation: The operator clicks the "Open" button for a valve on the HMI interface of the system host.

[0065] Host processing: The host software generates a control command containing information such as the target valve ID, action instruction, and timestamp. The host sends this command out using the encrypted channel established with the target gateway.

[0066] Gateway forwarding: The target smart gateway receives the encrypted data packet, decrypts it, and identifies it as a Modbus command addressed to one of its subordinate execution terminals. The gateway converts the command into a standard Modbus RTU / TCP frame and sends it out through the local network.

[0067] Terminal execution: The target execution terminal receives the Modbus frame and parses out the instruction content. Its internal control board drives the motor to execute the valve opening action.

[0068] Status feedback: While the action is being executed, the terminal's sensors monitor the valve status in real time. Once the valve reaches the fully open position or the opening degree required by the command, the terminal immediately collects the current status data, such as "fully open" or "100% opening degree", and encapsulates it into a Modbus response frame, which is then sent to the smart gateway.

[0069] Data upload: The gateway packages the terminal's response frame and transmits it back to the system host through the 4G encrypted channel.

[0070] Interface Updates and Log Recording: After decrypting the data, the host computer parses the latest valve status. On one hand, it updates the valve status display on the HMI interface in real time, such as the icon turning green and displaying "Open". On the other hand, it records the "operation command", "operation result", "timestamp" and other information completely in the operation log database for subsequent query and analysis.

[0071] It is worth noting that the application scenarios of the XPSys-A2024 series remote intelligent valve control system of this invention are mainly divided into two categories according to customer needs: those with a centralized pipeline management platform already built and those without a centralized control platform.

[0072] For those who have already built a centralized pipeline management platform: it can be integrated into the customer's data management platform through data docking.

[0073] For systems without a centralized pipeline management platform: establish a complete management system through the remote management software platform and supporting hardware of the control system itself to realize the operation and control of valves.

[0074] This invention provides a complete, efficient, safe and scalable remote intelligent valve control solution through the organic combination of hardware architecture, software functions and security methods. It effectively solves many of the problems mentioned in the background technology and has extremely high industrial application value.

[0075] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
