Description

Technical Field

[0001] This application relates to the field of oil tanker safety monitoring technology, and in particular to an IoT intelligent lead seal system for oil tankers. Background Technology

[0002] In the transportation of petrochemical products, tanker truck seals are crucial devices for preventing cargo theft and ensuring transportation safety; their technological level directly impacts the safety and management efficiency of the transportation process. Traditional seal technology faces many unresolved issues in practical applications: Traditional disposable physical lead seals rely on a one-time locking mechanism made of lead, plastic, or other materials to achieve a seal. Their simple physical structure makes them easily damaged. Criminals can easily open them with tools without leaving any obvious traces, resulting in extremely poor anti-tampering capabilities. Statistics show that the rate of abnormal opening of traditional physical lead seals during transportation is as high as 12.7%, posing a major security risk in the oil transportation process.

[0003] Early traditional lead seals relied entirely on their physical structure, lacking any information markings and thus failing to enable information-based management. Managers could not obtain status information during transportation through the seals, leading to a disconnect between seal status and transportation data, making effective traceability and supervision of the transportation process difficult. This management method is extremely inefficient in large-scale transportation scenarios and can no longer meet the needs of modern logistics management.

[0004] Some traditional lead seals have been augmented with information labels such as QR codes and barcodes, which, while facilitating management to some extent, are mostly printed or pasted onto the seal surface. During tanker truck transport, these labels are easily worn or damaged by friction, oil, rain, and other factors, making the information difficult to decipher. Actual measurements show that the effective recognition period for QR code labels in outdoor transport environments averages only 15 days, severely impacting the reliability of the seal information.

[0005] While electronic seals equipped with RFID tags and on-site communication capabilities achieve anti-counterfeiting and reusability, they still have key shortcomings in practical applications: They cannot provide real-time feedback on the seal's status to managers; the opening can only be determined afterward by reading the tag information, without knowing the specific time of opening. Furthermore, when a seal is illegally opened, it does not issue an alarm in a timely manner, preventing managers from taking immediate action and delaying risk management. Statistics from an oil transportation company show that 83% of these abnormal opening incidents of electronic seals were not detected in time, seriously affecting transportation safety.

[0006] Traditional lead seals involve multiple departments and personnel involved in sealing during use, including transportation, quality inspection, and supervision, but lack a unified digital information management method. Information is not shared between departments, and the status of the lead seals cannot be shared in real time. This makes it difficult to carry out tasks such as business surveys, inspections, and meter rotations efficiently, resulting in significant management loopholes and security risks.

[0007] Currently, the main technologies used in lead seal applications include disposable physical lead seals, disposable physical lead seals with information tags, and reusable electronic lead seals with on-site communication capabilities. These technologies either lack information technology support or cannot achieve real-time monitoring, and none of them can meet the modern tanker truck transportation's requirements for safe, intelligent, and traceable lead seal management. Summary of the Invention

[0008] To improve the security of oil tanker lead seal monitoring, this application provides an IoT intelligent lead seal system for oil tankers.

[0009] This application provides an IoT intelligent lead seal system for oil tankers, which adopts the following technical solution: it includes a lock assembly, a wire rope detection circuit, a wireless communication module, an NFC encryption tag, and a power supply module; The lock assembly includes a main body shell, a lock shell, a lock cylinder, a spring, and steel balls. The two lock assemblies are symmetrically arranged about the center line of the main body shell. Three steel balls with the same structure are arranged radially on the lock cylinder. The steel balls cooperate with the inclined surface of the inner wall of the lock shell to lock and unlock the steel wire rope. The wire rope detection circuit connects the wire rope to the circuit through a resistor and detects the connection status of the wire rope in real time by detecting the voltage change on the wire rope. The wireless communication module includes a main control MCU circuit with an integrated wireless transceiver and a wireless antenna, used to upload steel wire rope connection status information in real time. The NFC encryption tag has repeated read / write functionality and can be encrypted; it is used to store seal information and prevent counterfeiting. The power supply module is a disposable button battery used to power the entire system.

[0010] Optionally, the locking assembly drives the steel balls to move radially through the axial movement of the lock core, thereby controlling the locking and unlocking of the wire rope.

[0011] Optionally, the wire rope detection circuit outputs a high level when the wire rope is normally connected and a low level when it is disconnected. The main control MCU circuit determines the seal status based on the voltage signal.

[0012] Optionally, the wireless communication module uses a 433MHz or 2.4GHz wireless communication frequency band to achieve data interaction with the management platform.

[0013] Optionally, the NFC encryption tag uses the AES encryption algorithm to encrypt the stored information to prevent information forgery and tampering.

[0014] Optionally, when the main control MCU circuit detects that the wire rope has broken, it immediately sends an alarm message to the management platform via the wireless communication module.

[0015] In summary, this application includes the following beneficial technical effects: 1. Through the coordinated operation of the wire rope detection circuit and the wireless communication module, the system can detect the connection status of the lead seal in real time and upload the status information to the management platform in real time. When the wire rope is cut or the lead seal is illegally opened, the system immediately sends an alarm message to the management platform through the wireless communication module, so that the management personnel can be informed of the abnormality of the lead seal immediately; 2. The NFC encrypted tag features an encrypted design, and the stored seal information is encrypted to prevent forgery and tampering. The encryption algorithm uses the AES-128 standard, greatly increasing the difficulty of cracking. The lock components are designed so that the steel ball fits precisely with the inner wall of the lock shell, making it difficult for unauthorized personnel to open, further enhancing the seal's resistance to tampering. 3. The system connects to the management platform via a wireless communication module, enabling digital management of seal status information. The management platform can record data such as seal installation time, opening time, and location information in real time, forming a complete transportation traceability chain. Managers can query seal status and transportation data at any time through the management platform, providing efficient information technology tools for business surveys, inspections, and metering rotation. 4. The system enables the sharing of seal status information among multiple departments through a management platform. Transportation departments, quality inspection departments, regulatory departments, etc., can all obtain seal status and related data in real time through the management platform, realizing collaborative management among multiple departments.

[0016] 5. The lock assembly design allows for wire rope replacement. When the wire rope needs to be replaced due to normal use, simply cut the old wire rope and install the new one; the lock body is reusable. The disposable button battery has a lifespan of over 12 months, is easy to replace, and is inexpensive. Compared to traditional disposable lead seals, this system reduces operating costs by over 60% while also reducing lead seal waste, meeting environmental protection requirements.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0020] This application discloses an IoT-enabled intelligent lead seal system for oil tankers. For example... Figure 1-4 As shown, it includes a lock assembly, a wire rope 6 detection circuit, a wireless communication module, an NFC encryption tag, and a power supply module; The lock assembly includes a main body shell 1, a lock shell 2, a lock cylinder 3, a spring 4, and steel balls 5. The two lock assemblies are symmetrically arranged about the centerline of the main body shell 1. Three steel balls 5 with the same structure are arranged radially on the lock cylinder 3. The steel balls 5 cooperate with the inclined surface of the inner wall of the lock shell 2 to lock and unlock the steel wire rope 6. When the lock cylinder 3 moves axially, it drives the steel balls 5 to move axially. The change of the inclined surface of the steel balls 5 and the inner wall of the lock shell 2 causes the three steel balls 5 to increase or decrease radially, thereby realizing the locking or unlocking control of the steel wire rope 6. The design of the steel balls 5 will not damage the steel wire rope 6.

[0021] The wire rope 6 detection circuit connects the wire rope 6 to the circuit via a resistor, and measures the voltage across the wire rope 6 at the other end. When the wire rope 6 is properly connected, the circuit is open, and the voltage is high; when the wire rope 6 is disconnected, the circuit is closed, and the voltage becomes low. By detecting the voltage change across the wire rope 6, the connection status of the wire rope 6 can be detected in real time. The main control MCU circuit determines the seal status based on the voltage signal.

[0022] The wireless communication module includes a main control MCU circuit with an integrated wireless transceiver and a wireless antenna 9, used for real-time uploading of the connection status information of the wire rope 6. The main control MCU circuit collects the status information of the wire rope 6 detection circuit in real time and uploads the seal status to the management platform via the wireless antenna 9, while also receiving commands from the management platform. The wireless communication module uses the 433MHz or 2.4GHz wireless communication frequency band to achieve data interaction with the management platform. When the main control MCU circuit detects a break in the wire rope 6, it immediately sends an alarm message to the management platform via the wireless communication module.

[0023] NFC encrypted tags feature repeated read / write functionality and are encrypted. They employ the AES encryption algorithm to encrypt stored information, containing an NFC encrypted information tag to prevent counterfeiting of electronic seals. The NFC encrypted tag stores the seal's identity and status information, which can be read and written via NFC reader / writer devices. Its encryption design effectively prevents information forgery and tampering.

[0024] The power supply module includes a disposable button battery 8, which powers the entire system.

[0025] The implementation principle of the IoT intelligent lead seal system for oil tankers in this application embodiment is as follows: When an oil tanker needs to be sealed, both ends of a steel wire rope are inserted into two sets of locking assemblies. At this time, the steel wire rope is locked in the reverse direction by the steel balls inside the locking assemblies, and can only be inserted inward and cannot be pulled out, thus completing the locking state. After the locking assemblies lock the steel wire rope, the steel wire rope detection circuit detects that the steel wire rope is normally connected, the circuit voltage is high, and the main control MCU circuit uploads the locked state of the lead seal to the management platform in real time through the wireless antenna. The management platform records information such as the installation time and location of the lead seal.

[0026] During tanker truck transportation, the wire rope detection circuit continuously monitors the connection status of the wire rope. The main control MCU circuit collects the detected voltage signal in real time to determine whether the seal is in a normal connection state. The main control MCU circuit periodically uploads the seal status information to the management platform via a wireless antenna. The management platform displays information such as the seal status and vehicle location in real time. Managers can view the seal status at any time through the management platform, enabling real-time monitoring of the transportation process. When the tanker truck arrives at the transportation node, staff can use an NFC reader to read the information in the NFC encrypted tag, verifying the seal status and transportation data, ensuring the safety and traceability of the transportation process.

[0027] When criminals attempt to cut the steel wire rope or illegally open the lead seal, the steel wire rope detection circuit detects a break in the rope, causing the circuit voltage to drop to a low level. Upon detecting this voltage change, the main control MCU circuit immediately generates an alarm message. The main control MCU circuit transmits the alarm message to the management platform in real time via a wireless antenna, simultaneously triggering an audible and visual alarm. Upon receiving the alarm message, the management platform immediately notifies relevant management personnel and records the alarm time and location. After receiving the alarm, management personnel can take timely measures, such as notifying nearby patrol personnel to investigate or activating emergency plans, to ensure transportation safety.

[0028] When the tanker truck arrives at its destination and the seal needs to be opened normally, staff use a special tool to cut the steel wire rope. The wire 10 connecting the lock housing and circuit board 7 detects that the steel wire rope has been cut. At this point, the steel wire rope detection circuit detects the disconnection, and the main control MCU circuit sends the seal opening information to the management platform via a wireless antenna. The management platform records the opening time and operator information. If the steel wire rope needs to be replaced, staff remove the old steel wire rope, install the new one, and repeat the locking operation to re-lock the seal. After the replacement, the steel wire rope detection circuit detects a normal connection, and the main control MCU circuit uploads the new seal status to the management platform.

[0029] The management platform stores real-time data on the seal's status, alarm information, and location, and analyzes and processes this data. Managers can query historical data and generate transportation traceability reports through the platform, providing a basis for transportation management and safety assessments. When traceability of the transportation process is required, managers can use the platform to query the seal's installation and opening records, as well as changes in its status during transportation, ensuring transparency and traceability.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
