Description

Technical Field

[0001] This disclosure relates to the field of non-pipeline transportation and monitoring of oil and gas, and in particular to a control system and method for mobile oil and gas transportation. Background Technology

[0002] After oil and gas extraction, the gas is typically distributed to different well stations for processing or transportation, usually through the laying of corresponding pipelines. However, under certain conditions, such as complex terrain, remote areas, or small-scale oil fields, pipeline laying is difficult or even impossible. Furthermore, traditional pipeline systems lack flexibility; once built, they are poorly adaptable to changes in oil field production or transportation needs, and require ongoing maintenance costs. Therefore, for conditions such as complex terrain, remote areas, or small-scale oil fields, non-pipeline transportation methods are currently used for oil and gas transportation, such as using transport vehicles and ships to transport oil and gas under different conditions and road conditions.

[0003] However, in realizing the present invention, the inventors discovered the following technical problems with the related technologies: when using transport vehicles, transport ships, and other transport devices for oil and gas transportation, it is mostly based on manual handover and supervision is weak, which easily leads to supervision loopholes. For example, oil theft incidents occur frequently, and it is difficult to trace them based on manual handover methods; some solutions monitor the manual handover process by setting up cameras at stations, but in this case, it only supports post-event inquiries and cannot stop incidents in real time, such as emergencies or oil theft; at the same time, for some areas with complex terrain and remote areas, oil and gas transportation may face various road conditions and emergencies, and the existing supervision methods cannot achieve intelligent management and control of oil and gas transportation based on actual working conditions and road conditions. Summary of the Invention

[0006] In some embodiments, the fixed terminal node includes: a first controller and a multi-protocol interface unit. The multi-protocol interface unit is connected to a first tank valve locking mechanism and a first tank status sensor via a first communication interface; it is connected to an identity recognition terminal via a second communication interface.

The mobile terminal node includes: a second controller and a vehicle status monitoring unit. The vehicle status monitoring unit is connected to a second tank valve locking mechanism and a second tank status sensor via a third communication interface, and communicates with the server via a second wireless communication module.

[0007] In some embodiments, the multi-protocol interface unit includes an adaptive filtering circuit, a vibration spectrum analysis module, and a fault pre-diagnosis unit. The adaptive filtering circuit is configured with a programmable cutoff frequency for sampling the tank valve, wherein the signal sampling accuracy is dynamically adjusted according to the ambient noise level. The vibration spectrum analysis module is connected to the first tank valve locking mechanism and extracts the valve's mechanical vibration information from the sampled signal using wavelet packet decomposition to obtain vibration spectrum features. The fault pre-diagnosis unit incorporates a fault mode classifier based on a deep belief network, used to determine whether a fault exists in the tank and valve and the type of fault based on the vibration spectrum features, valve opening and closing time series, and ambient temperature and humidity data, and to report a site anomaly to the server if a fault exists.

[0010] In some embodiments, the server also supports dynamic planning processing of oil and gas transportation routes.

[0011] The aforementioned operating terminal or the aforementioned mobile terminal node initiates a transportation route planning request to the aforementioned server; wherein, after the aforementioned operating terminal initiates the aforementioned transportation route planning request, the aforementioned server interacts with the aforementioned mobile terminal node and obtains real-time traffic information captured by the mobile terminal node; or, the transportation route planning request sent by the aforementioned mobile terminal node carries: real-time traffic information captured by the mobile terminal node.

[0012] Before the aforementioned transport device is loaded, the aforementioned server determines the initial planned route through normal stations based on the reported real-time station status and sends the initial planned route to the aforementioned mobile terminal node; thereby enabling the aforementioned transport device to travel based on the initial planned route and report real-time traffic information.

[0013] The server determines whether the initial planned route needs to be adjusted based on the updated real-time status of the stations, the driving status of the transportation device, the storage tank status of the transportation device, and the real-time road condition information reported by the transportation device. If adjustment is required, the server determines the adjusted target planned route.

[0014] In some embodiments, at least one of the following conditions occurs, determining that an adjustment to the initial planned route is necessary:

[0015] The real-time status of the aforementioned stations indicates that one or more stations covered by the initially planned route have experienced an anomaly; or,

[0017] The above-mentioned driving status indicates that the power of the above-mentioned transport device is lower than the set value, and it needs to be charged or refueled; or,

[0018] The aforementioned driving status indicates that the actual driving trajectory of the aforementioned transportation device deviates from the aforementioned initially planned route by a margin exceeding a preset threshold; or,

[0019] The aforementioned driving status and real-time traffic information indicate that the actual driving trajectory of the aforementioned transportation device deviates from the aforementioned initial planned route by less than a preset threshold, but is about to enter or has already entered a controlled area not recorded in the road network data; or,

[0020] The aforementioned driving status indicator indicates that the storage tank status of the aforementioned transport device has at least one of the following issues: leakage or abnormal tank pressure; or,

[0021] The above driving status indicates that the above-mentioned transport device has malfunctioned.

[0022] In some embodiments, the well site is an oil and gas loading point or an oil and gas unloading point. The real-time status of the site includes at least one of the following: valve on / off status, abnormal conditions, node online status, tank status, and site monitoring video; the tank status includes at least one of the following: tank pressure, liquid volume, and liquid temperature. The driving status of the transportation device includes at least one of the following: driving parameters, driving trajectory, and driving behavior; the tank status includes at least one of the following: tank pressure, liquid volume, and liquid temperature.

[0023] In some embodiments, the fixed terminal node and the mobile terminal node are equipped with a mechanical emergency mechanism. This mechanical emergency mechanism supports authentication of the fixed terminal node and the mobile terminal node in offline mode after mechanical triggering, and supports local autonomous control of the first storage tank of the well site and the second storage tank of the transportation device after successful authentication. The control terminal has a visual interface for displaying or supporting the querying of the following information: operation event records, real-time site status, site monitoring video, transportation device driving status, transportation device tank status, and transportation device monitoring video. The operation event records include: identity recognition records and valve operation commands.

[0024] Secondly, embodiments of this disclosure provide a control method based on the aforementioned control system. The method includes: after the transport device arrives at the loading / unloading area of ​​the well site, at least one of a fixed terminal node or a mobile terminal node prompts the user to verify their identity; at least one of the fixed terminal node or the mobile terminal node initiates an oil / gas loading / unloading request to the control terminal; the oil / gas loading / unloading request carries the identity information of the requesting user; the control terminal interacts with the server to perform the following verification and remote control operations: verifying the identity information; after successful verification, analyzing whether the oil / gas loading / unloading conditions are met based on the real-time site status reported by the fixed terminal node, the driving status of the transport device reported by the mobile terminal node, and the tank status; if met, issuing control commands to the fixed terminal node and the mobile terminal node to control the first tank of the well site and the second tank of the transport device to simultaneously switch from a blocked state to a blocked-off state and automatically return to a blocked state after detecting that the oil / gas transmission volume has reached a preset value.

[0025] The technical solutions provided in the embodiments of this disclosure have at least some or all of the following advantages:

[0026] The aforementioned control system utilizes fixed nodes deployed at well sites for monitoring and control, mobile nodes deployed at transportation units for monitoring, and control terminals deployed in oil and gas production areas. A server provides data storage, communication routing, and data processing services to the control terminals. The fixed nodes monitor the real-time status of the well sites and report it to the server, while the mobile nodes monitor the operating status of the transportation units and the status of the storage tanks and report them to the server. This allows the control terminals to obtain and analyze real-time, 24 / 7 monitoring data from the sites and transportation units, enabling them to issue control commands based on real-time operating conditions. Specifically, during oil and gas loading and unloading, authentication and verification of loading / unloading conditions are implemented. The dual-verification logic ensures that only after successful verification will the first storage tank at the well site and the second storage tank of the transportation device be switched from a locked state to an unlocked state. Upon detecting that the oil and gas transmission volume has reached a preset value, the lock will automatically revert to a locked state. Because the valves of the corresponding storage tanks at the well site and transportation device are opened or closed synchronously after connection, this helps reduce or even prevent unauthorized personnel (such as those involved in oil theft) from opening the tanks and stealing oil, ensuring that the loading and unloading process is controlled and recorded throughout. Simultaneously, the server's ability to access real-time, 24 / 7 monitoring data from the site and transportation device helps to promptly detect anomalies and take corresponding countermeasures, achieving intelligent control over the entire loading, unloading, and transportation process.

[0036] Fixed node 110 and mobile node 120 respectively establish communication connections with server 130, for example in Figure 1 In the example, fixed node 110 uses a 4G network access switch and communicates with server 130 via a 4G network. Mobile node 120 uses a 4G network access switch and communicates with server 130 via a 4G network. Server 130 also communicates with control terminal 140 via a local area network (e.g., a wired LAN connection). In some embodiments, fixed node 110 and mobile node 120 can also communicate with each other.

[0037] The aforementioned fixed terminal node 110 is used to monitor the real-time status of the well station and report it to the aforementioned server.

[0038] The aforementioned mobile terminal node 120 is used to monitor the driving status of the transportation device and the status of the storage tank and report them to the aforementioned server.

[0039] The aforementioned control terminal 140 is used to: receive oil and gas loading / unloading requests initiated by at least one of the aforementioned fixed terminal node or the aforementioned mobile terminal node, wherein the oil and gas loading / unloading requests carry: the identity information of the requesting user; and interact with the aforementioned server 130 to perform the following verification and remote control operations: verify the aforementioned identity information, and after successful verification, analyze whether the oil and gas loading / unloading conditions are met based on the real-time status of the aforementioned site, the driving status of the aforementioned transportation device, and the status of the storage tank; if the conditions are met, issue control commands to the aforementioned fixed terminal node and the aforementioned mobile terminal node to control the first storage tank of the aforementioned well site and the second storage tank of the aforementioned transportation device to simultaneously switch from the blocked state to the blocked unblocked state and automatically restore the blocked state after detecting that the oil and gas transmission volume has reached a preset value.

[0040] In the embodiments of this disclosure, there is no limit to the number of fixed-end nodes and mobile-end nodes, and each node includes a main controller and several intelligent peripherals.

[0041] The aforementioned fixed terminal node 110 is used to monitor the real-time status of the well station and report it to the aforementioned server. In some embodiments, the well station is an oil and gas loading point or an oil and gas unloading point. The real-time status of the station includes, but is not limited to, at least one of the following: valve on / off status, abnormal conditions, node online status (used to indicate whether the oil production station and unloading station are online), the status of the station's storage tanks, and station monitoring video, etc. The status of the station's storage tanks can be obtained through monitoring by a first storage tank status sensor, including at least one of the following: station storage tank pressure, station storage tank liquid volume, and station storage tank liquid temperature. Based on the monitoring of the real-time status of the station, functions such as gas leakage monitoring and low-temperature alarm for storage tank liquid can be realized.

[0042] For example, refer to Figure 1 As shown, the fixed terminal node 110 includes: a site monitoring module, a face recognition module, a sensing and action execution module, and a status display module (e.g., displaying site tank pressure, site tank liquid volume, site tank liquid temperature, whether there are any abnormalities at the site, whether any transport vehicles have entered the site, etc.). The site monitoring module can monitor the real-time status of the site; for example, the site monitoring module may include: site camera equipment, site network monitoring equipment, etc. The sensing and action execution module includes, but is not limited to: a first tank status sensor, and a first tank valve locking mechanism.

[0043] In some embodiments, the fixed terminal node includes: a first controller (which can be understood as a main controller; to distinguish it from the main controller of the mobile terminal node, it is described as a first main controller; the main controller of the mobile terminal node will be described as a second controller thereafter) and a multi-protocol interface unit. The multi-protocol interface unit is connected to the first tank valve locking mechanism and the first tank status sensor via a first communication interface (e.g., an RS485 bus); it is connected to an identity recognition terminal (e.g., a face recognition module) via a second communication interface (e.g., an RS232 interface). The identity recognition terminal is used to verify identity and authorization for loading and unloading oil and gas; and it communicates with the server via a first wireless communication module. The mobile terminal node includes: a second controller and a vehicle status monitoring unit. The vehicle status monitoring unit is connected to the second tank valve locking mechanism and the second tank status sensor via a third communication interface, and communicates with the server via a second wireless communication module.

[0044] In some embodiments, the fixed endpoints may pre-store preset face IDs (as identity and authorization information) and periodically synchronize them with corresponding data on the server for subsequent local matching and comparison using face recognition (one method of identity and authorization verification, exemplified only; fingerprint recognition, password input, iris recognition, voiceprint recognition, and one or more combinations thereof can also be used). Local matching and comparison is performed when the fixed endpoints are offline, serving as a backup identification strategy. In other embodiments, the control terminal typically calls the server to perform the following authorization verification operation: verifying the identity information of the requesting user based on the identity and authorization information stored in the database or blockchain node.

[0045] In addition, the monitoring data of the well site can also include the process parameters of the well site.

[0046] Figure 2 A schematic diagram of the composition architecture of a fixed end node according to an embodiment of the present disclosure is shown.

[0047] In some embodiments of this disclosure, the fixed end node 110 may include a main controller (i.e., the first controller described above), an intelligent peripheral, and a multi-protocol interface unit for connecting the main controller and the intelligent peripheral. This multi-protocol interface unit is also used to connect the main controller and a server. For example, see reference to... Figure 2 As shown, the main controller of the fixed end node is connected to a 4G router via an Ethernet RJ45 interface (an example of the second wireless communication module), and then connected to the server via the 4G network; the main controller is connected to the sensing and action execution module inside the valve on the tank via an RS485 bus (an example of the first communication interface). Figure 2The example shown is a valve control and status acquisition module, which includes, for example, a first tank valve locking mechanism and a first tank status sensor. It can also be connected to secondary level and temperature gauges to display information such as the liquid volume and temperature of the station's tanks. The main controller also connects to a face recognition module via an RS232 interface (second communication interface), for example... Figure 2 The industrial-grade facial recognition module in the example verifies the identity and permissions of personnel performing unsealing operations during oil and gas loading or unloading. The IO data and facial recognition data corresponding to the above connections are collected and processed by the main controller of the fixed end node to form site monitoring data, including current real-time data and event data. This monitoring data is transmitted through a customized 4G network channel (e.g., based on...). Figure 2 The example 4G wireless communication transceiver transmits data to the server. In some embodiments, the first controller described above may also include a main control panel that can be manually operated.

[0048] For example, fixed node 110 specifically includes, but is not limited to: ground control cabinet, loading arm valve, level / temperature acquisition instrument, etc., to complete the control and management of oil tank, loading arm valve, and operation. The first controller is a high-performance embedded industrial computer with external interfaces including real-time Ethernet, RS485, CAN, TTL, etc. Other functional modules of the fixed node are connected to the main control module through a data communication bus, and the main controller module manages the other functional modules. The industrial-grade face recognition module serves as an identity recognition module, using binocular 3D + infrared acquisition, capable of high-performance computing, achieving rapid recognition, and meeting the requirements of outdoor, strong light, low light, high temperature, and high humidity working environments. The 4G transceiver module is an LTE 4G wireless industrial-grade router, realizing 4G to wired network port conversion, providing 150Mpps, and supporting IEEE802.11 / b / g / n wireless transmission protocols; the level / temperature acquisition secondary instrument collects the level and temperature of the oil tank through sensors, converts them into engineering quantities, and connects to the main control module via an RS485 communication link. The loading arm valve sealing control module, installed inside the loading arm valve, enables sealing control and status acquisition. Managed by an industrial-grade microcontroller, it collects real-time data on the valve's open / closed position and cover plate status, and receives management from the main control module to control the unlocking electromagnetic lock, achieving miniaturized unlocking control. The operation and management integration module, the core module within the ground control cabinet, manages the connections to the control panels within the assembly, the interfaces of each module, and the power supply to each module.

[0049] Server 130 is used to store monitoring data from fixed-end nodes 110. After analysis and processing, the data is stored in a database or uploaded to a blockchain storage system. The server can also manage the fixed-end nodes and issue control commands, such as controlling the opening and closing of the valve of the first storage tank in the monitoring well station.

[0050] In some embodiments, the multi-protocol interface unit includes: an adaptive filtering circuit, a vibration spectrum analysis module, and a fault pre-diagnosis unit.

[0051] The aforementioned adaptive filtering circuit is equipped with a programmable cutoff frequency for sampling the tank valves, wherein the signal sampling accuracy is dynamically adjusted according to the ambient noise level.

[0052] The aforementioned vibration spectrum analysis module is connected to the valve locking mechanism of the first storage tank. It extracts the mechanical vibration information of the valve by wavelet packet decomposition of the sampled signal to obtain the vibration spectrum characteristics.

[0053] The aforementioned fault pre-diagnosis unit has a built-in fault mode classifier based on deep belief networks, which is used to determine whether there is a fault in the storage tank and valve and the type of fault based on the aforementioned vibration spectrum characteristics, valve opening and closing time series and environmental temperature and humidity data, and to report the site anomaly to the aforementioned server if a fault exists.

[0054] The aforementioned fault mode classifier has been trained with training data, and a mapping relationship between input parameters and output prediction results has been pre-built. The input parameters include: vibration spectrum characteristics, valve opening and closing time series and ambient temperature and humidity data. The output prediction results are whether the storage tank and valve have faults, and if so, the specific fault type.

[0055] In this embodiment, by setting up a multi-protocol interface unit, it is helpful to realize efficient internal communication between the main controller of the fixed end node and the intelligent peripheral device, as well as high-quality communication between the main controller and the external server, and to be compatible with different types of protocol interfaces. In addition, considering the computing power limitation of the main controller of the fixed end node, by setting an adaptive filtering circuit, a vibration spectrum analysis module and a fault pre-diagnosis unit in the multi-protocol interface unit, the signal analysis and fault prediction processing logic is implemented in the multi-protocol interface unit. This can share the computing pressure of the first controller, share different computing tasks with the main controller for parallel processing, improve the overall processing efficiency of the fixed end node, and avoid the problems of large resource consumption and computing delay or low efficiency caused by deploying all listening (I) logic and computing logic on the first controller.

[0056] The aforementioned mobile terminal node 120 is used to monitor the driving status of the transport device and the status of the storage tank and report them to the aforementioned server 130. The driving status of the transport device includes at least one of the following: driving parameters (such as steering wheel angle, driving speed, driving acceleration, etc.), driving trajectory, driving behavior (driving behavior can be the driving behavior of a driver corresponding to manual driving, or the actual control behavior under some driving strategies corresponding to autonomous driving or assisted driving; such as driving habits in complex terrain (manual driving: whether the hands are off the steering wheel; autonomous / assisted driving: the control stability of the steering wheel on bumpy roads), whether to slow down when passing through areas with high pedestrian traffic, and the handling method when passing through areas with complex road conditions, such as slowing down, requesting dynamic route planning, etc.)). The storage tank status of the transport device includes at least one of the following: transport tank pressure, transport tank liquid volume, transport tank liquid temperature, and can realize functions such as gas leakage monitoring and low temperature alarm of storage tank liquid.

[0057] In some embodiments, the mobile terminal node includes a second controller and a vehicle status monitoring unit. The vehicle status monitoring unit is connected to the second tank valve locking mechanism and the second tank status sensor via a third communication interface, and communicates with the server via a second wireless communication module. In some embodiments, the vehicle status monitoring unit is also connected to a positioning unit (e.g., an on-board terminal) via a fourth communication interface to obtain the driving status of the transportation device.

[0058] For example, the mobile terminal node includes an onboard control box, a sealing and control arm valve, a position and speed acquisition module, etc., to manage and control the vehicle's trajectory and operating status. The main controller module is a high-performance embedded industrial computer with external interfaces including real-time Ethernet, RS485, CAN, TTL, etc. Other functional modules of the onboard mobile terminal node are connected to the main controller module via a data communication bus, and the main controller module manages the other functional modules. The position and speed acquisition module is the core module of the onboard system. It collects the vehicle's position and speed in real time and sends them to the main controller module via the data bus. The arm valve sealing and control module is installed inside the arm valve to realize the sealing and control of the arm valve and the acquisition of its status. It is managed by an industrial-grade microcontroller, collects the valve's open, closed, and cover plate status in real time, accepts management from the main control module, and controls the unlocking electromagnetic lock to achieve miniaturized unlocking control.

[0059] Figure 3 A schematic diagram illustrating the composition architecture of a mobile terminal node according to an embodiment of the present disclosure is shown.

[0060] For example, refer to Figure 3As shown, a mobile terminal node is installed inside the oil tanker and connected to a positioning module via RS485 (an example of the fourth communication interface) to acquire the vehicle's driving status in real time, such as real-time location, speed, acceleration, driving trajectory, and driving behavior. The aforementioned IO data and driving status are collected and processed by the mobile terminal node's edge scanning module to form current real-time data and event data. This data is transmitted to the server via a customized 4G network channel. The server stores the monitoring data from the mobile terminal node in a database or uploads it to a blockchain node after analysis and processing. The server manages the mobile terminal node and issues control commands, such as dynamically planning the mobile terminal node's driving route or controlling the opening and closing of the valves of the second storage tank in the transportation device. In the above embodiment, a fixed terminal node 110 and a mobile terminal node 120 communicate with the server 130 respectively as an example. In other embodiments, near-field communication can also be achieved between the fixed terminal node 110 and the mobile terminal node 120. For example, near-field communication can be achieved when the distance between the mobile terminal node 120 and the fixed terminal node 110 is less than a preset distance threshold (the threshold range for near-field communication, such as Bluetooth communication, local area network communication, etc.).

[0061] After the transport device arrives at the loading / unloading area of ​​the well site, at least one of the fixed terminal node 110 or the mobile terminal node 120 prompts the user to verify their identity. The fixed terminal node or the mobile terminal node initiates an oil / gas loading / unloading request to the control terminal. This request carries the identity information of the requesting user. In the above embodiment, taking a fixed terminal node equipped with a facial recognition module for identity verification as an example, since the facial recognition module is located at the well site, it generally ensures that the transport vehicle (an example of a transport device) is actually within the well site before verification. Therefore, the oil / gas loading / unloading request only needs to carry the identity information of the requesting user. In other embodiments, the mobile terminal node can also be equipped with a module for identity verification. When initiating the oil / gas loading / unloading request, the mobile terminal node needs to synchronously upload relevant proof of the requesting user's true geographical location and actual location (e.g., photos or videos of the well site), or the fixed terminal node can upload relevant proof records to the server, such as surveillance video evidence proving the transport vehicle is located within the loading / unloading area of ​​the well site.

[0062] The aforementioned control terminal interacts with the aforementioned server to perform the following verification and remote control operations: verifying the aforementioned identity information; after successful verification, analyzing whether the conditions for oil and gas loading and unloading are met based on the real-time status of the site reported by the fixed terminal node, the driving status of the transportation device reported by the mobile terminal node, and the status of the storage tank; if the conditions are met, issuing control commands to the aforementioned fixed terminal node and the aforementioned mobile terminal node to control the first storage tank of the aforementioned well station and the second storage tank of the aforementioned transportation device to simultaneously switch from the blocked state to the blocked unblocked state, and automatically restore the blocked state after monitoring that the oil and gas transmission volume has reached the preset value.

[0063] The server is a highly reliable, high-performance rack-mount server, meeting the needs for redundant backup of production data, dual power supply, and stable long-term operation. The server is equipped with a server operating system, database management system, and web service system. System application software is also installed on the server, resulting in faster local data storage speeds and meeting the data service needs of multiple nodes. The server provides multiple gigabit network connections to meet the needs of simultaneous access by multiple users.

[0064] The aforementioned control system utilizes fixed nodes deployed at well sites for monitoring and control, mobile nodes deployed at transportation units for monitoring, and control terminals deployed in oil and gas production areas. A server provides data storage, communication routing, and data processing services to the control terminals. The fixed nodes monitor the real-time status of the well sites and report it to the server, while the mobile nodes monitor the operating status of the transportation units and the status of the storage tanks and report them to the server. This allows the control terminals to obtain and analyze real-time, 24 / 7 monitoring data from the sites and transportation units, enabling them to issue control commands based on real-time operating conditions. Specifically, during oil and gas loading and unloading, authentication and verification of loading / unloading conditions are implemented. The dual-verification logic ensures that only after successful verification will the first storage tank at the well site and the second storage tank of the transportation device be switched from a locked state to an unlocked state. Upon detecting that the oil and gas transmission volume has reached a preset value, the lock will automatically revert to a locked state. Because the valves of the corresponding storage tanks at the well site and transportation device are opened or closed synchronously after connection, this helps reduce or even prevent unauthorized personnel (such as those involved in oil theft) from opening the tanks and stealing oil, ensuring that the loading and unloading process is controlled and recorded throughout. Simultaneously, the server's ability to access real-time, 24 / 7 monitoring data from the site and transportation device helps to promptly detect anomalies and take corresponding countermeasures, achieving intelligent control over the entire loading, unloading, and transportation process.

[0065] In some embodiments, the server includes a security control unit that integrates a blockchain evidence storage module and a dynamic access control policy engine; the identity information is verified based on the dynamic access control policy engine. The blockchain evidence storage module is used to store the monitoring data on the blockchain or to store the monitoring data on different blockchain nodes using a sharded storage method; the monitoring data includes at least one of the following: operation event records, real-time site status, site monitoring video, the operating status of the transport device, the tank status of the transport device, and monitoring video of the transport device; the operation event records include: identity recognition records and valve operation commands.

[0066] By setting up a blockchain-based evidence storage module, monitoring data corresponding to the entire loading, unloading, and transportation process can be stored in a real and tamper-proof manner. Simultaneously, based on sharded storage, large datasets are divided into smaller data blocks, each distributed across different nodes for storage and processing. This helps avoid data loss or service interruptions caused by single points of failure. Distributing loading and transportation data (such as potentially confidential transportation routes) across multiple nodes improves data security and reliability, reducing the risk of data leakage. Furthermore, data sharding allows for full utilization of existing hardware resources, reducing hardware and maintenance costs.

[0067] If the trajectory deviation of the transportation device exceeds the threshold, the mobile terminal node will upload the monitoring video captured by the vehicle-mounted equipment to the blockchain for real-time monitoring or tracing, to clarify the cause of the trajectory deviation of the transportation device and the corresponding response.

[0068] In some embodiments, analyzing whether the conditions for oil and gas loading and unloading are met based on the real-time status of the aforementioned site, the operating status of the aforementioned transportation device, and the status of the storage tank includes:

[0069] Based on the real-time status of the aforementioned stations, determine whether the stations are operating normally and are online; based on the driving status of the aforementioned transportation devices and the status of the storage tanks, determine whether the storage tanks are operating normally during transportation and whether the aforementioned transportation devices are within the loading and unloading area of ​​the stations.

[0070] Under the condition that the above-mentioned sites are operating normally and online, the storage tanks are in normal transportation and the above-mentioned transportation devices are in the loading and unloading area of ​​the sites, the analysis results that meet the conditions for oil and gas loading and unloading are obtained.

[0071] Send verification commands that require a response to the aforementioned fixed terminal node and the aforementioned mobile terminal node, and determine the difference in transmission link time between the aforementioned fixed terminal node and the aforementioned mobile terminal node based on the response information of the aforementioned verification commands.

[0072] Specifically, the transmission timestamps for sending control commands to the valve locking mechanisms of the first and second storage tanks are determined based on the differences in transmission link time, so that the first storage tank of the well site and the second storage tank of the transportation device receive the control commands synchronously to perform status control of the corresponding storage tanks.

[0073] By setting up a detailed judgment logic that analyzes whether the conditions for oil and gas loading and unloading are met based on the real-time status of the aforementioned sites, the driving status of the aforementioned transportation devices, and the status of the storage tanks, it helps to ensure that the actual working conditions meet the requirements of loading and unloading operations, and ensures the safety of the operations. In addition, it is possible to determine the difference in transmission link time between the fixed terminal node and the aforementioned mobile terminal node based on the response information of the verification command, and determine the transmission timestamp for sending control commands to the valve locking mechanisms of the first and second storage tanks respectively based on the difference in transmission link time. This allows the first storage tank of the aforementioned well site and the second storage tank of the aforementioned transportation device to receive control commands synchronously for corresponding tank status control, thereby achieving precise valve opening and closing control and ensuring controllable flow transmission after the first and second storage tanks are connected by the delivery pipeline.

[0074] In some embodiments, the server also supports dynamic planning processing of oil and gas transportation routes.

[0075] The aforementioned operating terminal or the aforementioned mobile terminal node initiates a transportation route planning request to the aforementioned server; wherein, after the aforementioned operating terminal initiates the aforementioned transportation route planning request, the aforementioned server interacts with the aforementioned mobile terminal node and obtains real-time traffic information captured by the mobile terminal node; or, the transportation route planning request sent by the aforementioned mobile terminal node carries: real-time traffic information captured by the mobile terminal node.

[0076] Before the aforementioned transportation device loads (e.g., loads and transports from the first station), the aforementioned server determines the initial planned route through normal stations based on the reported real-time status of the stations, and sends the initial planned route to the aforementioned mobile terminal node; thus enabling the aforementioned transportation device to travel based on the initial planned route and report real-time traffic information.

[0077] The server determines whether the initial planned route needs to be adjusted based on the updated real-time status of the stations, the driving status of the transportation device, the storage tank status of the transportation device, and the real-time road condition information reported by the transportation device. If adjustment is required, the server determines the adjusted target planned route.

[0078] In some embodiments, at least one of the following conditions occurs, determining that an adjustment to the initial planned route is necessary:

[0079] The real-time status of the aforementioned stations indicates that one or more stations covered by the initially planned route have experienced an anomaly; or,

[0080] The real-time status of the aforementioned stations indicates that one or more stations covered by the initially planned route have been offline for more than a preset duration; or,

[0081] The above-mentioned driving status indicates that the power of the above-mentioned transport device is lower than the set value, and it needs to be charged or refueled; or,

[0082] The aforementioned driving status indicates that the actual driving trajectory of the aforementioned transportation device deviates from the aforementioned initially planned route by a margin exceeding a preset threshold; or,

[0083] The aforementioned driving status and real-time traffic information indicate that the actual driving trajectory of the aforementioned transportation device deviates from the aforementioned initial planned route by less than a preset threshold, but is about to enter or has already entered a controlled area not recorded in the road network data (e.g., a temporary controlled area adjusted according to actual traffic or some special controlled areas where chemicals are strictly prohibited); or,

[0084] The aforementioned driving status indicator indicates that the storage tank status of the aforementioned transport device has at least one of the following issues: leakage or abnormal tank pressure; or...

[0085] The above driving status indicates that the above-mentioned transport device has malfunctioned.

[0086] In some embodiments, the fixed terminal node and the mobile terminal node are equipped with a mechanical emergency mechanism. This mechanical emergency mechanism supports authentication of the fixed terminal node and the mobile terminal node in offline mode after mechanical triggering, and supports local autonomous control of the first storage tank of the well site and the second storage tank of the transportation device after successful authentication. The control terminal has a visual interface for displaying or supporting the querying of the following information: operation event records, real-time site status, site monitoring video, transportation device driving status, transportation device tank status, and transportation device monitoring video. The operation event records include: identity recognition records and valve operation commands.

[0087] A second exemplary embodiment of this disclosure also provides a control method based on the above-described control system.

[0088] The above methods include:

[0089] After the transport device arrives at the loading and unloading area of ​​the well station, at least one of the fixed terminal node or the mobile terminal node prompts the user to authenticate.

[0090] At least one of the aforementioned fixed terminal nodes or the aforementioned mobile terminal nodes initiates an oil and gas loading / unloading request to the control terminal.

[0091] The aforementioned oil and gas loading / unloading request carries: the identity information of the requesting user; the aforementioned control terminal interacts with the aforementioned server to perform the following verification and remote control operations:

[0092] The above identity information is verified. After verification, the conditions for oil and gas loading and unloading are analyzed based on the real-time status of the station reported by the fixed terminal node, the driving status of the transportation device reported by the mobile terminal node, and the status of the storage tank.

[0093] Under the specified conditions, control commands are issued to the aforementioned fixed terminal node and the aforementioned mobile terminal node to control the first storage tank of the aforementioned well site and the second storage tank of the aforementioned transportation device to simultaneously switch from the blocked state to the blocked unblocked state, and automatically restore the blocked state after monitoring that the oil and gas transmission volume reaches the preset value.

[0094] For example, the oil and gas loading process is as follows: Within a specified time (operations outside the time control interval are invalid), the oil truck (example of the transportation device) arrives at the oil loading point (operations outside the positioning control range are invalid). The on-site personnel connect the second storage tank of the oil truck to the first storage tank of the well site, and use facial recognition to initiate an oil loading request to the control equipment. At this time, both the first and second storage tanks are in a locked state. The control terminal calls the server for authentication and remote control: The dispatcher remotely issues an unlocking command to the locking devices of the oil loading point and the oil truck (corresponding to the valve locking mechanisms of the first and second storage tanks) via the control terminal (unlocking control can be selected to unlock separately or all). The equipment will provide a prompt upon successful receipt of the command. Once the locking devices are unlocked and the valves are ready to open, oil loading automatically begins, and the system automatically locks again after reaching the set transportation volume. After oil loading is completed, the locking devices should provide a prompt (ideally with sound, voice, and light) when the valves are fully closed, and upload relevant status information to the server. They can also notify the control terminal.

[0095] Oil unloading process: Within the designated time (operations outside the time-controlled interval are invalid), the oil truck arrives at the unloading point (position control). On-site personnel connect the second storage tank of the oil truck to the first storage tank of the well site, and initiate an oil unloading request to the control equipment by facial recognition. At this time, both the first and second storage tanks are in a locked state. The control terminal calls the server for authentication and remote control: The dispatcher remotely issues an unlocking command to the locking device of the oil truck through the control terminal (unlocking control can be performed separately or all at once). After the device successfully receives the command, it will provide a prompt (suggested sound, voice, and light). The unlocking device is ready to open the valve, automatically unloading oil and automatically locking again after reaching the set transport volume. After unloading is completed, the locking device should provide a prompt (suggested sound, voice, and light) when the valve is fully closed, and upload relevant status information to the server. It can also notify the control terminal.

[0096] The status of all equipment on site is fed back to the server in real time and can be displayed or queried on the control terminal. It can also be filtered and searched in statistical analysis or log query, such as changes in lock status, changes in valve status, successful execution of the seal release command, successful facial recognition verification, equipment online status, equipment damage, the oil loading point of the oil truck, and the oil unloading point of the oil truck.

[0097] In some embodiments, the real-time map corresponding to the oil tanker should mark all oil loading points, unloading points, and the real-time location of the oil tanker, displayed using different icons. During trajectory playback, the relevant oil loading and unloading points should also be displayed, with the sealing and unlocking operations shown as icons. Playback speeds can be selected at 1x, 2x, 8x, 16x, etc., and the real-time status of the vehicle and locks should be displayed during playback. The control terminal also supports a function to query vehicle stopping time; users can query and select vehicles that have stopped for more than 30 minutes to record and display their location, lock status, etc.

[0098] Each time a user requests a facial recognition result, an image is uploaded and recorded to the backend server, which can be viewed and retrieved through the records.

[0099] In the aforementioned control method, fixed terminal nodes are deployed at well sites for monitoring (monitoring and control), mobile terminal nodes are deployed at transportation units for monitoring, and control terminals are deployed in oil and gas production areas. A server is also deployed to provide data storage, communication routing, and data processing services to the control terminals. The fixed terminal nodes monitor the real-time status of the well site and report it to the server, while the mobile terminal nodes monitor the operating status of the transportation unit and the status of the storage tanks and report them to the server. This allows the control terminals to obtain and analyze real-time monitoring data from the site and transportation unit around the clock, enabling them to issue control commands based on real-time operating conditions. Specifically, during oil and gas loading and unloading, identity verification and oil and gas loading / unloading condition verification are implemented. The dual-verification logic ensures that only after successful verification will the first storage tank at the well site and the second storage tank of the transportation device be switched from a locked state to an unlocked state. Upon detecting that the oil and gas transmission volume has reached a preset value, the lock will automatically revert to a locked state. Because the valves of the corresponding storage tanks at the well site and transportation device are opened or closed synchronously after connection, this helps reduce or even prevent unauthorized personnel (such as those involved in oil theft) from opening the tanks and stealing oil, ensuring that the loading and unloading process is controlled and recorded throughout. Simultaneously, the server's ability to access real-time, 24 / 7 monitoring data from the site and transportation device helps to promptly detect anomalies and take corresponding countermeasures, achieving intelligent control over the entire loading, unloading, and transportation process.
