[0002] Under the combined effects of complex and ever-changing hydrological environment, extreme weather disasters, and increasingly busy shipping activities, the accidental fall of containers carried by ships into the water has become a safety hazard that cannot be ignored. These fallen containers can be in three states: floating, sinking, and floating, depending on their interaction with the water body. Among them, containers in the sinking and floating states are not only difficult to be discovered in time because they are hidden under the water surface, but also containers in the floating state are affected by the tidal hydrodynamics of special waters such as the Yangtze River Estuary, and their positions are changeable, posing a serious threat to the safety of navigation in the waterway.

[0003] At the same time, water quality testing is also a very important task in water areas. The water environment also poses new challenges to the search and disposal of containers that have fallen into the water. Water pollution is likely to accelerate the corrosion process of containers and their cargoes, causing secondary environmental risks. In water quality testing, water samples need to be collected, and they need to be filtered before collection, which requires a filter.

Of course, they are only examples, and the purpose is not to limit the present application.

[0042] See also Figure 1-3The present invention provides a technical solution: an emergency position indicating device for a container that has fallen into water and a rapid positioning and tracking method thereof, comprising a float 1, a float rope 8 is arranged at the bottom of the float 1, a strong magnet 9 is arranged at the other end of the float rope 8, a flashing belt and a positioning device are arranged on the outer surface of the float 1, an opening and closing mechanism and a collecting mechanism are arranged inside the float 1, the opening and closing mechanism and the collecting mechanism correspond to each other, a square frame 5 is connected to the bottom of the opening and closing mechanism, a filter frame 52 is connected inside the square frame 5, a filter screen 12 is connected inside the filter frame 52, a vibration mechanism is arranged on one side of the filter frame 52, a scraping mechanism is arranged on one side of the filter screen 12, and the vibration mechanism and the scraping mechanism correspond to each other.

[0043] Specifically, when the emergency position indicator is needed, first, the crew on board throws the strong magnet 9 to the place where the container falls into the water within a certain range from the container that falls into the water. When the strong magnet 9 is adsorbed on the surface of the container, the float 1 is dropped. When the strong magnet 9 fails to be adsorbed on the surface of the container, the float 8 is pulled out of the water by hand and thrown again until it is adsorbed. The float 8 plays the role of connecting the float 1 and the strong magnet 9. The float 1 is also equipped with a positioning device such as a flashing belt and a satellite positioning. The selected strong magnet 9 is connected to the float 1 by a nylon float 8. When the container falls into the water from the ship, the satellite positioning function is manually turned on, and the flashing belt plays a striking role. The strong magnet 9 is thrown to the container that falls into the water and adsorbed. After adsorption, the float 1 may move with the submerged container. At this time, the relevant personnel can open the opening and closing mechanism, and part of the water enters the interior of the float 1, so that the internal collection mechanism can collect and detect the water quality. One side of the float 1 is equipped with a small solar charging panel to charge the internal battery to meet the power needs of the float 1. The bottom of the opening and closing mechanism is connected to a square frame 5, and the inside of the square frame 5 is connected to a filter 12 and a filter frame 52. When facing relatively dirty waters, the filter 12 will be blocked, thereby affecting the collection. At this time, the filter 12 can be thoroughly cleaned by the cooperation of the scraping mechanism and the vibration mechanism to ensure its continuous filtering effect. By providing a strong magnet 9, it is ensured that it can be firmly attached to the container that has fallen into the water, and it can remain stable even on the rough sea surface, thereby greatly improving the accuracy of positioning. The positioning marker is simple to locate and easy to operate, and has high applicability. By providing an opening and closing mechanism and a collection mechanism, the water quality can be tested to provide valuable data for the environmental protection department. It is helpful to understand the pollution situation of the water area, take timely measures to protect the ecological environment, and provide certain water quality information for the rescue of containers.

[0044] Reference Figure 4-12 The floating ball 1 and the floating rope 8 are detachably connected, and the floating rope 8 and the strong magnet 9 are detachably connected.

[0045] Specifically, the float 1, the float rope 8, and the strong magnet 9 can all be disassembled, so that different strengths of magnets and floats 1 can be equipped to cope with different environments, and the overall adaptability is high.

[0046] The opening and closing mechanism includes a cylinder 4, a frame 13 is arranged inside the float 1, a circular ring plate 15 is fixedly connected to the bottom of the frame 13, the cylinder 4 and the circular ring plate 15 are fixedly connected, the output end of the cylinder 4 is connected to a piston rod 41, one side of the piston rod 41 is fixedly connected to an opening and closing block 42, a circular groove 16 is arranged inside the circular ring plate 15, a fixed block 17 is fixedly connected inside the circular groove 16, a water inlet 11 is fixedly connected to the bottom of the fixed block 17, and the opening and closing block 42 corresponds to the fixed block 17.

[0047] Specifically, when the relevant personnel want to collect water samples, the cylinder 4 is opened through the controller, and the piston rod 41 contracts, pulling the opening and closing block 42 to one side. At the beginning, the opening and closing block 42 and the fixed block 17 are in contact with each other, and the fixed block 17 and the water inlet 11 are fixedly connected. The part between the fixed block 17 and the water inlet 11 is empty, and the opening and closing block 42 just fills the part between the fixed block 17 and the water inlet 11. In the initial state, the opening and closing block 42 fits tightly with the fixed block 17, and the fixed block 17 is firmly connected to the water inlet 11. The space between the two blocks is originally empty, and the design of the opening and closing block 42 just fills this gap, forming a sealed barrier. In this way, when the opening and closing block 42 is closed, water can only reach the vicinity of the opening and closing block 42 and cannot enter the interior of the collection mechanism of the float 1. When the opening and closing block 42 moves slightly to the left, there is a gap between the opening and closing block 42 and the middle of the fixed block 17, and water can flow into the interior of the collection mechanism. Only a small gap is needed for the water sample to come in and be tested, so it can be opened briefly and then closed again. By providing an opening and closing mechanism, the water sample can enter the interior of the collection mechanism of the float 1, thereby realizing the detection of water quality.

[0048] The opening and closing block 42 is in a square shape, with a notch inside, a protrusion fixedly connected to the inner side of the notch, and a groove is formed on one side of the fixing block 17, and the protrusion and the groove correspond to each other.

[0049] Specifically, the opening and closing block 42 is square and round. Because it cooperates with the fixed block 17, when the opening and closing block 42 is opened, water will only flow in from the middle. The parallel part of the square part of the opening and closing block 42 is always in contact with the fixed block 17, so that no water will leak when it is opened. The vertical part of the square part of the opening and closing block 42 will be away from the fixed block 17, so that water can enter. There is a convex block on the inner side of the opening and closing block 42. When it is closed, the convex block is just inserted into the groove on the side of the fixed block 17, so as to ensure the sealing performance.

[0050] The collecting mechanism comprises a motor 2, a T-bar 14 is fixedly connected to the middle of a frame 13, the T-bar 14 and the motor 2 are fixedly connected, an intermittent mechanism is connected to one side of the motor 2, a support block 25 is fixedly connected to the bottom of the intermittent mechanism, a plurality of sampling tubes 26 are fixedly connected to one side of the support block 25, the sampling tubes 26 correspond to the circular groove 16, the sampling tubes 26 and the circular ring plate 15 are rotatably matched, a cylinder 23 is fixedly connected to the bottom of the T-bar 14, a piston rod 23 is connected to the output end of the cylinder 23, a detector 32 is fixed to one side of the piston rod 23, the detector 32 corresponds to the sampling tube 26, the top of the sampling tube 26 is made of rubber, a cross seam 27 is provided on the top of the sampling tube 26, the cross seam 27 corresponds to the detector 32.

[0051] Specifically, first, one of the sampling tubes 26 of the collection mechanism is just facing the circular groove 16, so that once the opening and closing mechanism is opened, water can flow into the inside of the sampling tube 26. The sampling tube 26 is actually not large, and the amount of water stored is not much, so it will not have too much weight. After a sampling tube 26 collects a water sample, as the float 1 moves to a certain position, the relevant personnel turn on the motor 2 through the controller, and the intermittent mechanism rotates with the support block 25 and multiple sampling tubes 26. The intermittent mechanism allows the support block 25 to rotate at a certain angle each time, so that each time the next sampling tube 26 just faces the circular groove 16, and sampling can be collected at multiple locations, making the sampling results more universal. The sampling tube 26 rotates just on the top of the circular plate 15, and the bottom of the sampling tube 26 fits with the circular plate 15. In this way, the sampling tube 26 that collects the water sample fits and rotates, and the water sample inside does not flow out. The detector 32 is connected to the sensor, and the detected data can be transmitted to the database through the sensor. The detector 32 can be inserted into the cross seam 27 to detect the water sample inside. When the detector 32 is pulled out, the cross seam 27 can return to its original state, that is, return to the sealed state. Therefore, the top is rubber and has a certain elasticity. By providing a sampling mechanism and multiple sampling tubes 26, multiple sampling can be performed. By providing a collection mechanism, continuous sampling at different positions can be achieved. The sampling results are made more comprehensive and representative, which helps to more accurately evaluate the water quality status. The evaluation of the water quality status also has a certain impact on the search and subsequent processing of containers.

[0052] The intermittent mechanism includes a rotating shaft 21, which is fixedly connected to the output end of the motor 2. A first gear 22 is fixedly connected to one side of the rotating shaft 21. The first gear 22 is an incomplete gear. A second gear 23 is meshedly connected to one side of the first gear 22. A vertical rod 24 is fixedly connected to the middle of the second gear 23. The vertical rod 24 and the T-bar 14 are rotatably connected, and the vertical rod 24 and the support block 25 are fixedly connected.

[0053] Specifically, when the relevant personnel turn on the motor 2, the rotating shaft 21 at the output end rotates, so that the first gear 22 rotates, and the second gear 23 rotates, so that the vertical rod 24 in the middle rotates, the support block 25 rotates, and the sampling tube 26 rotates, and the opening and closing mechanism cooperates to achieve continuous sampling. The first gear 22 has only a few teeth, and the few teeth can rotate the sampling tube 26 to a certain angle. When it rotates to the part without teeth, the sampling tube 26 stops rotating. Because the number of teeth of the first gear 22 is fixed, the angle of each rotation of the sampling tube 26 is also fixed. Therefore, one sampling tube 26 can be arranged with another sampling tube 26 to reach the top of the circular groove 16, thereby achieving continuous sampling and multiple sampling.

[0054] The scraping mechanism includes a double-headed motor 6, the square frame 5 is connected to the water inlet 11, a sealing block 51 is fixedly connected to one side of the square frame 5, the double-headed motor 6 is fixedly connected to the inner side of the sealing block 51, and both output ends of the double-headed motor 6 are fixedly connected to a rotating shaft 2 61, one side of the rotating shaft 2 61 at one end is connected to the vibration mechanism, and one side of the rotating shaft 2 61 at the other end is fixedly connected to a round block 1 62, one side of the round block 1 62 is fixedly connected to a protrusion 1 63, the outer side of the protrusion 1 63 is slidably connected to a circular ring block 1 64, one side of the circular ring block 1 64 is fixedly connected to a moving rod 65, the moving rod 65 and the inside of the square frame 5 are slidably connected, and one side of the moving rod 65 is fixedly connected to a scraper block 66, and the scraper block 66 corresponds to the filter screen 12.

[0055] Specifically, when the staff wants to scrape the filter 12 to maintain a continuous filtering effect, the staff turns on the double-headed motor 6 through the controller. The double-headed motor 6 is firmly mounted on the inner side of the sealing block 51, and the sealing block 51 is fixedly connected to one side of the frame 5, ensuring the stability and sealing of the entire scraping mechanism. After the double-headed motor 6 is started, its two output ends begin to rotate synchronously, driving the two rotating shafts 2 61 to rotate respectively. Among them, one rotating shaft 2 61 is connected to the vibration mechanism, and the vibration effect is generated by rotation, which helps to loosen and separate impurities attached to the filter 12. The other rotating shaft 2 61 is connected to the round block 1 62 and the protrusion 1 63. With the rotation of the rotating shaft 2 61, the round block 1 62 and the protrusion 1 63 also begin to rotate synchronously. The outer side of the protrusion 1 63 is slidably connected to the circular ring block 1 64, and the protrusion 1 63 can drive the circular ring block 1 64 to move back and forth left and right when rotating. The protrusion 63 is cylindrical. When the protrusion 63 rotates from bottom to top, it moves from right to left in addition to from bottom to top. In this way, while sliding inside the circular ring block 64, it also pushes the circular ring block 64 to move to one side, thereby promoting the movement of the circular ring block 64. One side of the circular ring block 64 is fixedly connected to the moving rod 65, and the moving rod 65 is slidably connected inside the square frame 5. In this way, the left and right movement of the circular ring block 64 is transmitted to the scraping block 66 through the moving rod 65. The scraping block 66 can perform scraping.

[0056] The vibration mechanism includes a bevel gear 1 7, which is fixedly connected to the rotating shaft 2 61, one side of the bevel gear 1 7 is meshedly connected with a bevel gear 2 71, one side of the bevel gear 2 71 is fixedly connected with a cross bar 72, the cross bar 72 and the inner side of the square frame 5 are rotatably connected, one side of the cross bar 72 is fixedly connected with a round block 2 73, one side of the round block 2 73 is rotatably connected with a protrusion 2 74, the outer side of the protrusion 2 74 is slidably connected with a circular ring block 2 75, the inner side of the square frame 5 is fixedly connected with a limiting block 54, one end of the circular ring block 2 75 and the limiting block 54 are rotatably connected Then, the other end of the circular block 2 75 is rotatably connected with a protrusion 3 76, and the outer side of the protrusion 3 76 is slidably connected with a circular block 3 77, and the top of the circular block 3 77 is fixedly connected with a vibration rod 78. The inner side of the square frame 5 is fixedly connected with two positioning blocks 55, and the vibration rod 78 and the positioning block 55 are slidably connected. The vibration rod 78 corresponds to the filter frame 52. The inner side of the square frame 5 is provided with a circular groove around, and the filter frame 52 is inside the circular groove. The four corners of the filter frame 52 are fixedly connected with springs 53, and the spring 53 and the inner side of the circular groove are fixedly connected.

[0057] Specifically, when the double-headed motor 6 is started and drives one of the rotating shafts 2 61 to rotate, the bevel gear 1 7 fixedly connected to the rotating shaft 2 61 also rotates accordingly. The rotation of the bevel gear 1 7 is transmitted to the bevel gear 2 71 through the meshing relationship, so that the bevel gear 2 71 starts to rotate. A crossbar 72 is fixedly connected to one side of the bevel gear 2 71, and the crossbar 72 is connected to the inner side of the square frame 5 through a rotational connection, so that the crossbar 72 can rotate inside the square frame 5 as the bevel gear 2 71 rotates. The rotation of the crossbar 72 drives the rotation of the round block 2 73 fixedly connected to one side thereof. The second round block 73 is rotatably connected with the second protrusion 74. Because the second protrusion 74 is in the shape of a square block, it can better fit the inner side of the second circular ring block 75. Therefore, the second protrusion 74 needs to be rotatable, so that it can better cooperate with the swing of the second circular ring block 75. When the second round block 73 rotates, because the second circular ring block 75 and the bottom limiting block 54 are rotatably connected, the second circular ring block 75 swings left and right accordingly, and while swinging, it moves the third protrusion 76 on the top left and right (the third protrusion 76 is also in the shape of a square block, the same principle as before), that is, the third circular ring block 77 moves left and right, so that the vibration rod 78 moves left and right inside the positioning block 55 to knock the filter frame 52. In addition, the four corners of the filter frame 52 are fixedly connected with springs 53, and the other end of the spring 53 is fixedly connected to the inner side of the circular groove. This design allows the filter frame 52 to be buffered and rebounded by the elastic action of the spring 53 when it is struck or pushed by the vibration rod 78, thereby enhancing the vibration effect and helping to more thoroughly remove impurities and dirt on the filter screen 12. The device can thoroughly clean the filter screen and maintain its filtering effect by providing a scraping mechanism and a vibration mechanism. At the same time, the two mechanisms only use one double-headed motor 6, saving the device and saving costs.

[0058] An embodiment of a rapid positioning and tracking method for an emergency position indicating device for a container that has fallen into water in an embodiment of the present invention includes:

[0059] 101. Obtain action information (water fall trigger, time interval K, command acceptance), respond to the action information, enter the positioning action command, obtain the action distance parameter according to the positioning action command, set the action distance parameter to D, then:

[0060]

[0061] Wherein: D represents the action distance parameter, that is, the three-dimensional distance from the point where the container falls into the water to the current position; (x1, y1, z1) represents the three-dimensional coordinates of the point where the container falls into the water; (x2, y2, z2) represents the three-dimensional coordinates of the current position of the container; if the action distance parameter is greater than the preset parameter, the main communication mode (Beidou short message communication) is entered, otherwise the auxiliary communication mode is established;

[0062] It should be noted that the initial condition settings are: Water fall trigger threshold: When the acceleration sensor detects an acceleration change exceeding the set threshold, it is determined to be a water fall trigger. Time interval K: set to every 10 seconds; preset parameters: The action distance threshold T is set to 1000 meters, which is used to determine whether to switch to the main communication mode.

[0063] Water drop trigger and initial positioning

[0064] - Overboard trigger: When a container falls into water accidentally, the acceleration sensor detects a sudden acceleration change that exceeds the set threshold and triggers the emergency position indicating device.

[0065] -Initial positioning: The emergency position indicating device immediately starts the built-in Beidou positioning module to obtain the three-dimensional coordinates of the falling point, which are set to (x1, y1, z1) = (120.12345°, 30.67890°, -5 meters) (longitude, latitude, altitude).

[0066] Positioning action instructions and data acquisition

[0067] - Positioning action command: The device responds to the water fall trigger, issues a positioning action command, and activates the continuous positioning function.

[0068] -Data acquisition: Every time interval K (10 seconds), the device acquires the three-dimensional coordinates of the current position. Set the coordinates acquired after the first 10 seconds to (x2, y2, z2) = (120.12350°, 30.67895°, -10 meters).

[0069] Use the formula to calculate the action distance parameter D:

[0070]

[0071] Substitute the data:

[0072]

[0073]

[0074] -Judgment: Since the action distance parameter D (5 meters) is less than the preset parameter T (1000 meters), the device decides to establish the auxiliary communication mode.

[0075] - Execution: The device establishes short-range communication with nearby rescue vessels through low-power Bluetooth technology, transmitting the precise location information of the fallen container in real time.

[0076] The device will continue to track the location of the container and update the positioning data at intervals K. If at a certain point in time, the action distance parameter D exceeds the preset parameter T, the device will automatically switch to the main communication mode (Beidou short message communication) to ensure reliable transmission of positioning information at longer distances.

[0077] It is understandable that the execution subject of the present invention may be an emergency position indicating device for a container that has fallen into water, or may be a terminal or a server, which is not specifically limited here. The embodiment of the present invention is described by taking a server as the execution subject as an example.

[0078] 102. In response to the entry, obtain location information, container status data, and environmental perception data, package the container according to the latitude and longitude, timestamp, container status data, and environmental perception data to obtain a simplified package, send the simplified package according to the main communication mode, and trigger the positioning action instruction again;

[0079] It should be noted that:

[0080] 1. Response to enter the main communication mode

[0081] Once the action distance parameter exceeds the preset threshold, the device determines that it needs to enter the main communication mode. In this example, the action distance parameter D is set to have reached 1200 meters, exceeding the preset threshold of 1000 meters.

[0082] 2. Obtain location information, container status data, and environmental perception data

[0083] Location information: Get the latitude and longitude of the current container through the Beidou positioning module. Set the current longitude and latitude to (118.234567°, 29.765432°). Timestamp: Record the exact time when the data is acquired, in the format of "YYYY-MM-DDHH:MM:SS". Set the current timestamp to "2024-11-1316:50:30". Container status data: Includes the switch status, internal temperature, humidity, etc. of the container. Set the current container door to be closed, the internal temperature to 25°C, and the humidity to 60%. Environmental perception data: Get surrounding environmental information such as water temperature, water flow speed, etc. through the environmental sensors on the device. Set the current water temperature to 20°C and the water flow speed to 0.5 m / s.

[0084] 3. Data packaging to obtain a streamlined package

[0085] The above acquired data is packaged according to the preset format to generate a simplified package. The simplified package format may be as follows: [location information][timestamp][container status][environmental perception data]

[0086] The simplified package after filling with specific data is:

[0087] 118.234567,29.765432,2024-11-1316:50:30,Close,25,60,20,0.5

[0088] Among them, each data is separated by commas to facilitate subsequent analysis.

[0089] Send a simplified packet according to the main communication mode

[0090] Use the Beidou short message communication function to send the packed streamlined package to the designated rescue center or monitoring platform. During the sending process, the device will ensure the integrity and accuracy of the data.

[0091] Trigger the positioning action command again

[0092] After sending the simplified package, the device will trigger the positioning action command again to continue tracking the location changes of the container. This helps provide real-time location updates to the rescue team and improve rescue efficiency.

[0093] 103. In response to the establishment, activate a short-range wireless communication unit, including Bluetooth, WiFi direct connection or LoRa, to establish a communication connection with a nearby maritime patrol ship, other containers or shore-based facilities, transmit preliminary location information and emergency status identification of the container, and trigger the positioning action instruction again;

[0094] It should be noted that the short-range wireless communication of the emergency position indicating device for the fallen container realizes:

[0095] 1. Respond and activate the NFC unit

[0096] 1.1 Response conditions: When the emergency positioning device of the fallen container determines that the auxiliary communication mode needs to be established, it will respond to this command.

[0097] 1.2 Activate wireless communication: The microcontroller in the device sends a command to activate the short-range wireless communication unit. In this example, Bluetooth 4.0 is selected as the communication method.

[0098] 2. Establish a communication connection

[0099] 2.1 Search nearby devices: The emergency location indicating device for the fallen container searches for Bluetooth devices equipped on nearby maritime patrol vessels, other containers or shore-based facilities through Bluetooth broadcasting.

[0100] 2.2 Establish connection: Set the device to successfully search for the Bluetooth signal "MPCVessel123" of a nearby maritime patrol vessel and successfully establish a Bluetooth connection with it.

[0101] 3. Transmit preliminary location information and emergency status identification

[0102] 3.1 Preliminary location information: The emergency location indicating device of the fallen container sends the preliminary location information to the maritime patrol ship through the established Bluetooth connection. The preliminary location information is set to longitude 120.12345° and latitude 30.67890°.

[0103] 3.2 Emergency status identification: At the same time, the device also sends an emergency status identification, indicating that the current container is in an emergency state and needs rescue. This identification can be a simple binary code, such as "1" for emergency state and "0" for normal state. In this example, the emergency status identification sent is "1".

[0104] 4.Trigger the positioning action command again

[0105] 4.1 Repositioning: After sending the preliminary location information and emergency status identification, the emergency positioning device of the fallen container triggers the positioning action command again to obtain more accurate location information.

[0106] 4.2 Update location information: After 10 seconds, the device obtains new location information through the Beidou positioning module. The longitude is 120.12350° and the latitude is 30.67895°.

[0107] 4.3 Continuous Tracking and Updates: The device will continue to track the location of the container and regularly send updated location information to the maritime patrol vessel via Bluetooth to assist in rescue efforts.

[0108] Specific example: Response and activation: The device responds to the auxiliary communication mode instruction and activates the Bluetooth communication unit. Establish connection: Successfully establish a connection with the Bluetooth device "MPCVessel123" of a nearby maritime patrol ship. Transmit data: Send preliminary location information (longitude 120.12345°, latitude 30.67890°) and emergency status indicator "1". Re-positioning: Re-trigger the positioning action instruction to obtain new location information (longitude 120.12350°, latitude 30.67895°). Continuous tracking: Continuously track and update location information and send it to the maritime patrol ship via Bluetooth.

[0109] 104. In any communication mode, if the primary communication mode is responded to N times continuously, the secondary communication mode is established for the N+1th time, and if the secondary communication mode is responded to T times continuously, the primary communication mode is established for the T+1th time.

[0110] It should be noted that the N value setting: the threshold number of consecutive responses to the main communication mode (such as Beidou short message communication) is set to 3 times. T value setting: the threshold number of consecutive responses to the auxiliary communication mode (such as Bluetooth, WiFi direct connection, etc.) is set to 5 times. Communication mode switching logic: After the main communication mode is used for N consecutive times, the N+1th time will automatically switch to the auxiliary communication mode; when the auxiliary communication mode is used for T consecutive times, it will automatically switch to the main communication mode for the T+1th time.

[0111] Implementation steps

[0112] Initial state:

[0113] When the device starts up, the initial communication mode is the main communication mode.

[0114] First to third communication:

[0115] The device sent positioning information and emergency status three times in succession through the main communication mode (Beidou short message).

[0116] After each transmission, a counter is incremented to record the number of times the main communication mode has been used consecutively.

[0117] Fourth communication:

[0118] After reaching the N value (3 times), the device automatically switches to auxiliary communication mode during the 4th communication.

[0119] At this time, a connection was established with a nearby maritime patrol ship via Bluetooth, and the preliminary location information and emergency status identification of the container were transmitted.

[0120] The fifth to ninth communications:

[0121] The device continues to use the auxiliary communication mode (Bluetooth) for data transmission.

[0122] After each transmission, another counter is incremented to record the number of times the auxiliary communication mode has been used consecutively.

[0123] Tenth communication:

[0124] After reaching the T value (5 times), the device automatically switches back to the main communication mode at the 10th communication.

[0125] At this time, the device again sends the updated positioning information and status through Beidou short message.

[0127] Main communication mode usage times: First 3 times (satisfying N value)

[0128] Auxiliary communication mode usage times: Next 5 times (satisfying T value)

[0129] Mode switching point: the 4th switching from the primary communication mode to the secondary communication mode; the 10th switching from the secondary communication mode back to the primary communication mode.

[0130] In the embodiment of the present invention, through the acceleration sensor and the Beidou positioning module, the device can quickly trigger an emergency response after the container falls into the water, and accurately obtain the three-dimensional coordinates of the falling point, providing key information for subsequent rescue work. According to the action distance parameter, the most suitable communication mode is automatically selected, which can not only realize real-time data transmission through low-power wireless communication methods (such as Bluetooth) in close range, but also ensure reliable transmission of information through Beidou short message communication at long distances. It can continuously track the location of the container and regularly send updated positioning information and status, so that the rescue team can grasp the latest location of the container in real time and improve the rescue efficiency. By introducing the automatic switching mechanism of the communication mode, the device can flexibly adjust the communication mode according to the actual use situation, which not only avoids the unnecessary use of high-power long-distance communication methods in close range, but also ensures the reliability of long-distance communication.
