Description

Technical Field

[0001] This invention belongs to the field of customs supervision equipment technology, and in particular relates to a mobile video customs sealing device, system and supervision method for ships. Background Technology

[0002] In the field of ship customs supervision, customs seals are an important technical means to ensure the safety of cargo transportation and prevent illegal opening and irregular operations. Currently, the customs seals commonly used in ship supervision mainly include two categories: traditional mechanical seals and fixed electronic seals.

[0003] Traditional mechanical customs seals have a simple structure and mainly rely on physical locking to achieve sealing. They lack information collection and remote monitoring capabilities, cannot perceive changes in the status of the sealed area in real time, and are difficult to detect and handle abnormal situations in a timely manner. They can no longer meet the requirements of modern customs supervision for informatization and intelligence.

[0004] Fixed electronic seals typically integrate cameras, sensors, and communication modules, enabling remote monitoring and data transmission via wired or wireless means, thus improving regulatory capabilities compared to mechanical seals. However, these seals are mostly fixed in place, making it difficult to adjust the installation location and monitoring angle after deployment. This makes them unsuitable for the complex structures of ship cargo holds and the varied stacking patterns of cargo, easily creating blind spots in supervision. For example, in the cargo holds of container ships or bulk carriers, fixed seals often only cover the hatch opening or a localized area, offering limited monitoring capabilities for the depths of the hold, corners, and gaps between cargo, providing opportunities for violations.

[0005] Furthermore, existing electronic gate sealing devices are typically heavily reliant on the ship's power supply system. Installation requires wiring or connection to the ship's power interface, limiting installation locations and complicating the deployment process. This is particularly true for older vessels or temporary monitoring scenarios, where wiring modifications are costly and difficult to implement, impacting the actual effectiveness of the equipment. If the ship's main power supply fails or is intentionally cut off, the electronic gate sealing devices will struggle to operate continuously, potentially causing monitoring disruptions.

[0006] To improve deployment flexibility, some mobile monitoring devices have attempted to use battery power. However, due to the high power consumption of functions such as video acquisition, data processing, and wireless communication, these devices have limited battery life in long-distance voyages or ocean shipping scenarios, often requiring frequent charging or battery replacements, making it difficult to support continuous and highly reliable monitoring needs. Once the power is depleted, the device will enter a state of failure, creating a monitoring gap.

[0007] From a regulatory perspective, most existing ship sealing devices remain at the stage of single-point, passive monitoring. When anomalies occur, they typically only provide simple alarms or post-event data queries, lacking the ability to classify and assess anomalies, deter them on-site, and proactively intervene remotely. Furthermore, there is a lack of effective coordination mechanisms between existing sealing devices and with other regulatory equipment, making it difficult to quickly verify anomalies by linking other regulatory resources, thus hindering overall regulatory efficiency and emergency response capabilities.

[0008] In summary, existing ship sealing technologies still have shortcomings in terms of deployment flexibility, monitoring coverage, power supply independence, and proactive handling and collaborative verification capabilities for abnormal events. There is an urgent need for a new ship sealing technology solution that can adapt to the complex regulatory environment of ships, support flexible deployment, have continuous operation capabilities, and achieve proactive response and collaborative supervision in abnormal situations. Summary of the Invention

[0009] The technical problem to be solved by the present invention is that existing customs sealing equipment has problems such as fixed installation location, excessive reliance on ship system power supply, insufficient monitoring endurance, and inability to monitor in real time from multiple angles.

[0010] To address the aforementioned problems, this invention provides a mobile video surveillance device, system, and monitoring method for ships, comprising: an energy harvesting component 101, an information acquisition component 201 with one end fixedly connected to the energy harvesting component 101 and the other end fixedly connected to a ball joint adjustment component 301, and an adjustable magnetic mounting base 401 with one end fixedly connected to the ball joint adjustment component 301. The invention is characterized in that the magnetic force of the adjustable magnetic mounting base 401 is used to fix the base, and the ball joint adjustment component 301 is adjusted to align the information acquisition component 201 with the monitoring target. During monitoring, the energy harvesting component 101 collects ambient light energy, which is then converted into electrical energy by the information acquisition component 201 to maintain monitoring operations.

[0011] Furthermore, the energy harvesting assembly 101 comprises a single silicon solar panel 105 for harvesting light energy, a bottom cover 103, a silicone sealing ring 104 disposed in an annular sealing groove on the mating surface of the bottom cover 103, and a transparent top cover 102.

[0012] Furthermore, the information acquisition component 201 is rectangular in shape and has an embedded information acquisition function component.

[0013] Furthermore, the ball joint adjustment assembly 301 includes: a ball joint bracket 302 and a mounting adapter 303 disposed at the lower part of the ball joint bracket 302, wherein the ball joint bracket 302 supports horizontal rotation and pitch adjustment.

[0014] Furthermore, the adjustable magnetic fixing base 401 includes: a neodymium iron boron permanent magnet 402 and a controllable magnetic switch 403 disposed on the neodymium iron boron permanent magnet 402.

[0015] Furthermore, the information acquisition component 201 is embedded with information acquisition function components, including: a CMOS sensor camera 202 for video acquisition in the middle of the front surface of the information acquisition component 201, a photosensitive sensor 204 disposed below the CMOS sensor camera 202, a spotlight 206 disposed at the top of the front surface of the information acquisition component 201, an omnidirectional MEMS microphone 203 disposed at the bottom of the information acquisition component 201, and a battery pack 205 embedded in the information acquisition component 201.

[0016] Furthermore, the bottom cover 103, the silicone sealing ring 104 disposed in the annular sealing groove of the bottom cover 103, and the transparent top cover 102 form a roughly similar box-shaped protective shell, and the single silicon solar panel 105 is embedded in the bottom cover 103.

[0017] The present invention also provides a ship mobile video sealing system, comprising: an energy supply unit 11, an acquisition unit 21 and a data processing and transmission unit 31 respectively connected to the energy supply unit 11 via a circuit bus, and a data processing and transmission unit 31 connected to the acquisition unit 21 via a data bus.

[0018] Furthermore, the energy supply unit 11 includes: a lithium battery energy storage module 12, used to store electrical energy converted by the power management module 13, realizing the storage and release of electrical energy; the power management module 13, used to convert light energy into electrical energy to perform maximum power point tracking charging of solar energy, and to execute power line switching logic in real time according to the status of the power supply line; the data processing and transmission unit 31 includes: a central processing module 32, which compresses and encodes the collected raw audio and video data; a 5G communication module 33, which uploads the processed data to the remote monitoring center in real time; and a local storage module 34, which performs local backup of the collected raw audio and video data; the central processing module 32 is connected to the 5G communication module 33 and the local storage module 34 respectively via a data bus.

[0019] The present invention also provides a method for movable video sealing of a ship, characterized by comprising the following steps: S1. Continuously sense the closed coverage area through video, audio and ambient light change information; S2. When physical intrusion, object throwing, abnormal sound, or abnormal light change is detected, it is determined to be an abnormal event. S3. Classify abnormal events according to their type and confidence level, and trigger corresponding response strategies. S4. For abnormal events that reach the preset risk level, trigger a local audible and visual alarm and lock the audio and video data within the preset time window before and after the abnormal event. S5. Once an abnormal event is confirmed, the system background generates an alarm message and pushes a notification message to the terminal of the on-duty personnel through the monitoring system interface. S6. Regulatory personnel send remote intercom commands to the ship's movable video sealing device based on abnormal events to implement voice intervention on site; S7. When an abnormal event reaches the linkage threshold, the system triggers the corresponding heterogeneous monitoring unit to perform on-site verification tasks according to the type and location of the abnormal event; the heterogeneous monitoring unit includes an aerial monitoring unit and / or an underwater monitoring unit.

[0020] Compared with existing technologies, the mobile video sealing device, system, and method for ships provided by this invention employs a collaborative design of controllable magnetic fixation and ball joint adjustment components. This enables rapid deployment and multi-angle monitoring of the sealing equipment on various metal surfaces of ships, effectively eliminating blind spots in supervision. Simultaneously, the self-powered structure of this invention allows the device to operate continuously for extended periods even when disconnected from the ship's power supply system, significantly improving the continuity and reliability of supervision. Through multimodal anomaly perception and hierarchical response strategies, it can promptly detect abnormal events, achieve on-site deterrence, and completely retain evidence data. Relying on event-driven human-machine collaborative intervention and multi-equipment linkage mechanisms, it further enhances the efficiency of anomaly verification and emergency response capabilities, comprehensively improving the level of intelligent ship supervision and the effectiveness of law enforcement evidence collection.

[0022] Figure 7 A schematic diagram of the process for a mobile video sealing method for ships. Detailed Implementation

[0023] To better understand the purpose, structure, and function of the present invention, a mobile video sealing device, system, and method for ships according to the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] like Figure 1 The present invention relates to a mobile video surveillance device for ships. This device includes an energy harvesting component 101, an information acquisition component 201 whose two ends are respectively fastened to the energy harvesting component 101 and a ball-joint adjustment component 301, and an adjustable magnetic mounting base 401 fixed to the bottom of the ball-joint adjustment component 301. The adjustable magnetic mounting base 401 enables quick and detachable fixing of the device to the ship's metal surface. The ball-joint adjustment component 301 enables multi-degree-of-freedom angle adjustment of the information acquisition component 201 when the device is fixed. The energy harvesting component 101 and the energy storage component in the information acquisition component 201 cooperate to form an independent power supply unit, used to maintain continuous operation of the device when disconnected from the ship's power supply system. Through the coordinated operation of the above components, the device can adapt to the deployment requirements of different monitoring locations such as ship cargo holds, hatches, and inside containers.

[0025] like Figure 2 As shown, the energy harvesting assembly 101 has a monosilicon solar panel 105 for collecting solar energy, a generally similar box-shaped protective housing consisting of a bottom cover 103, a silicone sealing ring 104 disposed in an annular sealing groove on the mating surface of the bottom cover 103, and a transparent top cover 102.

[0026] In practical implementation, multiple 20W rated power single-silicon solar panels 105 are embedded in the bottom cover 103 of the protective casing, thereby preventing the single-silicon solar panels 105 from being corroded by the complex environment of high humidity and high salt spray on ships. Among them, the bottom of the bottom cover 103 of the protective casing is provided with two threaded mounting posts, which can be fixed to the information acquisition component 201 by anti-vibration screws.

[0027] like Figure 3 As shown, the information acquisition component 201, which is fastened to the energy collection component 101 and the ball joint adjustment component 301 at both ends, is roughly cuboid in shape, and the information acquisition component 201 has an embedded information acquisition function component.

[0028] Specifically, the information acquisition function components include a CMOS sensor camera 202 for video acquisition in the middle of the front surface of the information acquisition component 201, and a photosensitive sensor 204 located below the CMOS sensor camera 202. To meet the supplementary lighting requirements for daytime and nighttime video acquisition, a spotlight 206 is provided on the top of the front surface of the information acquisition component 201. While meeting the on-site video acquisition needs, an omnidirectional MEMS microphone 203 located at the bottom of the information acquisition component 201 collects on-site audio.

[0029] Since the ship's power supply is unstable and other power supply methods are insufficient to support the operation of the device, a lithium-ion battery pack 205 is installed inside the information acquisition component 201 to convert light energy into electrical energy and store it in the lithium-ion battery pack 205. The light energy collected by the energy harvesting component 101 is converted into electrical energy by the power management module 13 and stored in the lithium-ion battery pack 205, which is used to power the information acquisition component 201 and related electronic components.

[0030] like Figure 4 As shown, the ball joint adjustment assembly 301 has a ball joint bracket 302 and a mounting adapter 303 disposed at the lower part of the ball joint bracket 302.

[0031] In practical implementation, one end of the spherical universal joint bracket 302 is bolted to the bottom of the information acquisition component 201, and the other end is bolted to the adapter 303. To eliminate visual and auditory blind spots during ship transportation, the spherical universal joint bracket 302 supports 360-degree horizontal rotation and ±90-degree pitch adjustment. By rotating the spherical universal joint bracket 302, the information acquisition component 201 located at the top is driven, thereby ensuring that the information acquisition component 201 can be flexibly aimed at any target that needs to be monitored from multiple angles, and complete the synchronous acquisition of audio and video.

[0032] like Figure 5 As shown, the adjustable magnetic fixing base 401 specifically includes a neodymium iron boron permanent magnet 402 and a controllable magnetic switch 403 disposed on the neodymium iron boron permanent magnet 402.

[0033] In practical implementation, the neodymium iron boron permanent magnet 402 of the adjustable magnetic fixing base 401 is bolted to the mounting adapter 303 of the ball joint adjustment assembly 301. During ship transportation, for convenient installation and flexible and reliable positioning, a high-strength neodymium iron boron permanent magnet 402 is used, utilizing strong magnetic force to quickly attach the entire device to the metal surface of the ship.

[0034] like Figure 6 As shown, this embodiment of the invention also provides a ship mobile video sealing system, which includes: an energy supply unit 11 supplying power to a data acquisition unit 21 and a data processing and transmission unit 31 via a circuit bus, and the data acquisition unit 21 being connected to the data processing and transmission unit 31 via a data bus.

[0035] The energy supply unit 11 consists of a lithium battery energy storage module 13 and a power management module 12.

[0036] The lithium battery energy storage module 13 is used to store the electrical energy converted by the power management module 12, thereby realizing the storage and release of electrical energy. The power management module 12 is used to convert light energy into electrical energy to charge the solar energy using maximum power point tracking, and to execute power line switching logic in real time according to the status of the power supply line.

[0037] In specific implementation, the single silicon solar panel 105 is connected to the power management module 12 through power lines. The power management module 12 is responsible for converting light energy into electrical energy, supplying power to the system's main power bus, acquisition unit 21, data processing and transmission unit 31, and other units, and intelligently managing the storage and distribution of electrical energy. To prevent insufficient battery life during nighttime operation, the power management module 12 stores excess electrical energy during the day into the lithium battery 12.

[0038] Acquisition unit 21 acquires video and audio signals from the monitoring site from multiple directions; In practice, the CMOS sensor camera 202 and MEMS microphone 203 acquire video and audio signals from the monitoring site from multiple directions and connect them to the data processing and transmission unit 31 via a data bus. The data processing and transmission unit 31 includes a central processing module 32, a 5G communication module 33, and a local storage module 34. The central processing module 32 is connected to the 5G communication module 33 and the local storage module 34 via a data bus. The central processing module 32 compresses and encodes the acquired raw audio and video data; The 5G communication module 33 uploads the processed data to the remote monitoring center in real time; The local storage module 34 performs local backup of the acquired raw audio and video data; In practical implementation, the central processing module 32 in the data processing and transmission unit 31 receives video and audio signals from the monitoring site collected by the acquisition unit 21 via a data bus. It compresses and encodes the collected video and audio signal data, and simultaneously transmits the processed data to the 5G communication module 33 via the data bus while also performing local replication to prevent data loss. Upon receiving the processed audio and video data, the 5G communication module 33 uploads the processed data to the remote monitoring center in real time via the 5G network.

[0039] For example, inside a ship's cargo hold, a metal surface that can cover the main monitored area without obstruction is selected, and the magnetic force of the adjustable magnetic mounting base 401 is activated by rotating the controllable magnetic switch 403. The neodymium iron boron permanent magnet 402 at the bottom of the adjustable magnetic mounting base 401 then generates a strong attraction force, fixing the device in the predetermined position.

[0040] Furthermore, after fixing, the spherical universal joint bracket 302 of the ball joint adjustment assembly 301 can be manually adjusted to precisely align the viewing angles of the CMOS sensor camera 202 and the MEMS microphone 203 with the key areas that need to be monitored.

[0041] Furthermore, regarding energy supply, the energy harvesting component 101 at the top of the device continuously receives ambient light energy and converts it into electrical energy. The electrical energy efficiently charges the lithium-ion battery pack 205 through the power management module 12 equipped with the MPPT algorithm, while simultaneously powering all electronic components.

[0042] Once in working condition, the CMOS sensor camera 202 acquires high-definition video streams according to a preset strategy, while the MEMS microphone 203 simultaneously acquires ambient audio and the photosensor 204 monitors environmental changes in real time.

[0043] like Figure 7 The present invention also provides a method for monitoring and sealing a ship using a mobile video barrier, the detailed steps of which are as follows: S1. Continuously sense the closed coverage area through video, audio and ambient light change information; S2. When physical intrusion, object throwing, abnormal sound, or abnormal light change is detected, it is determined to be an abnormal event. Specifically, when the system detects abnormal events such as physical intrusion, throwing of objects, abnormal sounds, abnormal changes in lighting, or unauthorized personnel activity in the monitored area, the system enters the corresponding alert mode according to the type of abnormal event.

[0044] S3. Classify abnormal events according to their type and confidence level, and trigger corresponding response strategies. Specifically, the central processing module 32 can classify abnormal events by risk based on their type, duration, location, and related characteristics, and trigger corresponding response strategies.

[0045] S4. For abnormal events that reach the preset risk level, trigger a local audible and visual alarm and lock the audio and video data within the preset time window before and after the abnormal event. Specifically, for abnormal events that reach the preset risk level, the system can trigger an audible and visual alarm locally. The spotlight 206 can automatically turn on to provide supplementary lighting and lock the audio and video data within a preset time window before and after the abnormal event. The local audible and visual alarm can immediately deter abnormal behavior on site. The spotlight 206 is used to improve the clarity of abnormal images in low-light environments. The central processing module 32 saves the locked audio and video data in the local storage module 34 to form traceable regulatory evidence.

[0046] S5. Once an abnormal event is confirmed, the system background generates an alarm message and pushes a notification message to the terminal of the on-duty personnel through the monitoring system interface. Specifically, the central processing module 32 compresses and encodes the collected audio and video data, and then uploads it to the customs monitoring center in real time through the 5G communication module 33. In the event of weak network signal or communication interruption, the system temporarily stores the relevant data in the local storage module 34 and retransmits it after the communication is restored. The system background can automatically generate alarm information based on the uploaded abnormal event information and push abnormal event prompts, video clips of the corresponding time period, or relevant evidence data to the terminal of the on-duty personnel so that the supervisory personnel can obtain abnormal information in a timely manner.

[0047] S6. Regulatory personnel send remote intercom commands to the ship's movable video sealing device based on abnormal events to implement voice intervention on site; Specifically, based on abnormal events, on-duty personnel can initiate remote intercom commands to the sealing device through the system backend to make voice announcements, issue warnings, or convey instructions to the site. Through the remote intercom function, remote proactive intervention in abnormal behavior on site can be achieved, thereby improving the timeliness of abnormal handling.

[0048] S7. When an abnormal event reaches the linkage threshold, the system triggers the corresponding heterogeneous monitoring unit to perform on-site verification tasks according to the type and location of the abnormal event; the heterogeneous monitoring unit includes an aerial monitoring unit and / or an underwater monitoring unit.

[0049] Specifically, the aerial monitoring unit can be an unmanned aerial vehicle (UAV) or similar device, while the underwater monitoring unit can be an underwater robot or similar device. Through the collaborative operation of these heterogeneous monitoring units and the sealing device of this invention, an expansion from single-point monitoring to multi-dimensional collaborative monitoring can be achieved.

[0050] After the voyage is completed or the supervision task is finished, customs officers only need to rotate the controllable magnetic switch 403 to release the magnetism, and the device can be removed from the installation position. The entire monitoring data can be exported via wired or wireless means. The exported monitoring data can be used for subsequent verification, evidence collection or supervision record retention.

[0051] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
