[0001] This invention relates to the field of ship data acquisition and transmission technology, and in particular to a multi-sensor wireless acquisition and transmission system and method for ship collision data. Background Technology
[0002] With the development of the shipbuilding industry, more and more ships are being used in rivers or oceans. During the operation of these ships, some potential and hard-to-detect dangers may occur, which can seriously endanger the normal operation of the ships. This can not only damage the ships and cause huge economic losses, but may even lead to major casualties. Therefore, collecting ship data when an accident occurs is of great significance for improving ship navigation safety.
[0003] In existing technologies, sensors are mainly used to collect analog signals, which are then transmitted to a data box or central control room near the machine via hard wires. Some manufacturers use analog-to-digital converters (digital acquisition cards) in the data box near the machine, and then uniformly send the converted digital signals to the central control console.
[0004] Currently, existing technologies use hard-wired or network cables to collect and transmit data. While this method is simple and easy to implement, the connection between the collection and transmission systems is easily disrupted after a ship accident, making it impossible to collect and transmit data after a collision. Summary of the Invention

[0008] The collision detection module is used to determine whether an accident has occurred on the ship based on the ship's status data. When an accident occurs, it sends a control signal to the multi-sensor acquisition box.
[0009] The multi-sensor acquisition box is used to sample the ship's status data at high frequency, mark the ship's damage data in the ship's status data according to the control signals, and send the ship's status data and ship damage data to the analog-to-digital converter.
[0010] The analog-to-digital converter is used to convert ship status data and ship damage data into digital signals and send the digital signals to the data storage module;

[0012] In some possible implementations, the collision detection module includes a comprehensive analysis unit and a signal transmission unit; the comprehensive analysis unit is connected to the signal transmission unit.
[0013] The comprehensive analysis unit is used to comprehensively analyze the ship's surrounding environment data, ship acceleration data, and ship vibration data to determine whether a collision has occurred.
[0014] The signal transmitting unit is used to generate control signals when a collision occurs on a ship, and then transmits the control signals to the multi-sensor acquisition box via a wireless communication module.
[0015] In some possible implementations, the multi-sensor acquisition box includes a signal acquisition unit and a tagging unit; the signal acquisition unit and the tagging unit are connected.
[0016] The signal acquisition unit is used to collect high-frequency data on the ship's surrounding environment, ship acceleration, and ship vibration.
[0017] The marking unit is used to mark the ship's state data collected after a collision accident based on the control signals, thereby obtaining ship damage data.
[0018] In some possible implementations, the analog-to-digital converter is an A / D converter; the A / D converter samples the ship's status data and ship damage data at preset time intervals and converts the analog signals into digital signals.
[0019] In some possible implementations, the wireless communication module is at least one of a local area network module, a radio frequency communication module, and a microwave communication module.
[0020] In some possible implementations, the data storage module includes a storage server and a protective enclosure; the storage server is housed within the protective enclosure.
[0021] The storage server is used to store the digital signals converted from the ship's status data and ship damage data, respectively.
[0022] The protective casing is used to protect the storage server from damage.
[0023] In some possible implementations, the integrated analysis unit is at least one of an electronic computer, a microcomputer, or a single-chip microcomputer.
[0024] In some possible implementations, the signal acquisition unit includes at least one of radar, temperature sensor, pressure sensor, smoke sensor, and water level sensor.

[0028] Determine whether the distance between the ship and surrounding obstacles exceeds the safe distance based on the data of the ship's surrounding environment;
[0029] When the distance between the ship and surrounding obstacles exceeds the safe distance, the ship's acceleration data is used to determine whether the degree of change in the ship's acceleration exceeds a preset threshold.
[0030] When the change in the ship's acceleration exceeds a preset threshold, the ship's vibration is judged based on the ship's vibration data to determine whether the ship's vibration exceeds a preset amplitude.
[0031] When the ship's vibration exceeds the preset amplitude, a control signal is sent to mark the ship's status data within the preset time range as ship damage data;
[0032] Ship status data and ship damage data are stored on separate servers.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0039] This invention provides a multi-sensor wireless acquisition and transmission system and method for ship collision data, which will be described below.
[0040] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the multi-sensor wireless acquisition and transmission system for ship collision data provided by the present invention. A specific embodiment of the present invention discloses a multi-sensor wireless acquisition and transmission system for ship collision data, including a collision detection module 100, a multi-sensor acquisition box 200, an analog-to-digital converter 300, a wireless communication module 400, and a data storage module 500; wherein, the multi-sensor acquisition box 200 is connected to the collision detection module 100 and the analog-to-digital converter 300 respectively through the wireless communication module 400, and the analog-to-digital converter 300 is connected to the data storage module 500;
[0041] The collision detection module 100 is used to determine whether the ship has had an accident based on the ship's status data. When the ship has had an accident, it sends a control signal to the multi-sensor acquisition box 200.
[0042] The multi-sensor acquisition box 200 is used to sample the ship's status data at high frequency, mark the ship's damage data in the ship's status data according to the control signal, and send the ship's status data and ship damage data to the analog-to-digital converter 300.
[0043] The analog-to-digital converter 300 is used to convert ship status data and ship damage data into digital signals and send the digital signals to the data storage module 500;
[0044] The data storage module 500 is used to receive digital signals and store them in the server.
[0045] Compared with the prior art, this embodiment provides a multi-sensor wireless acquisition and transmission system for ship collision data. The system includes a collision detection module 100, a multi-sensor acquisition box 200, an analog-to-digital converter 300, a wireless communication module 400, and a data storage module 500. The multi-sensor acquisition box 200 is connected to the collision detection module 100 and the analog-to-digital converter 300 via the wireless communication module 400. The analog-to-digital converter 300 is connected to the data storage module 500. The collision detection module 100 is used to determine whether an accident has occurred based on the ship's status data. When the ship... In the event of an accident, a control signal is sent to the multi-sensor acquisition box 200. The multi-sensor acquisition box 200 is used to sample the ship's status data at high frequency, mark the ship damage data in the ship's status data according to the control signal, and send the ship's status data and the ship damage data to the analog-to-digital converter 300. The analog-to-digital converter 300 is used to convert the ship's status data and the ship damage data into digital signals, and send the digital signals to the data storage module 500. The data storage module 500 is used to receive the digital signals and store the digital signals in a server. This invention provides a multi-sensor wireless acquisition and transmission system and method for ship collision data. A collision detection module 100 determines whether a collision has occurred. When a collision occurs, the system uses control signals to separately mark the ship's damage data. A wireless communication module 400 transmits the ship's status data and damage data, which are then separately stored by a data storage module 500. This overcomes the limitations of existing technologies where data cannot be collected and transmitted after a collision when the ship is damaged. It effectively collects and stores ship operational data and solves the problems of high workload and difficulty in repairing and replacing wired transmission lines when they fail, thus reducing maintenance costs and complexity.
[0046] In some embodiments of the present invention, the collision detection module 100 includes a comprehensive analysis unit 110 and a signal transmission unit 120; the comprehensive analysis unit 110 is connected to the signal transmission unit 120.
[0047] The comprehensive analysis unit 110 is used to comprehensively analyze the ship's surrounding environment data, ship acceleration data, and ship vibration data to determine whether the ship has experienced a collision accident.
[0048] The signal transmitting unit 120 is used to generate a control signal when a collision occurs on the ship, and transmit the control signal to the multi-sensor acquisition box 200 through the wireless communication module 400.
[0049] In the above embodiment, the comprehensive analysis unit 110 can perform a comprehensive analysis based on the ship's surrounding environment, ship acceleration, and ship vibration during navigation. First, it determines whether there are any obstacles around the ship that may cause a collision based on the ship's surrounding environment. Then, it determines the changes in the ship's acceleration. At this time, it is also necessary to consider whether the driver changed the ship's acceleration. When, in addition to the driver changing the ship's acceleration, there is an external force that causes a sudden change in the ship's acceleration, it is preliminarily determined that a collision accident has occurred. Further analysis is then performed in conjunction with the ship's vibration during navigation. When the ship's vibration exceeds a preset amplitude, it is determined that a collision accident has occurred. The accident detection module immediately generates a collection signal and sends the collection signal to the multi-sensor acquisition box 200.
[0050] The control signal generated and transmitted by the signal transmitting unit 120 can be a pulse signal. After the control signal is sent to the multi-sensor acquisition box 200, the multi-sensor acquisition box 200 will mark the acquired ship status data according to the acquisition time and mark the data within the preset time range as ship damage data.
[0051] In some embodiments of the present invention, the multi-sensor acquisition box 200 includes a signal acquisition unit 210 and a marking unit 220; the signal acquisition unit 210 is connected to the marking unit 220.
[0052] Among them, the signal acquisition unit 210 is used to acquire high-frequency data of the ship's surrounding environment, ship acceleration data, and ship vibration data;
[0053] The marking unit 220 is used to mark the ship's state data collected after a collision accident based on the control signal to obtain ship damage data.
[0054] In the above embodiments, the signal acquisition unit 210 includes various types of sensors to acquire data from multiple dimensions of the ship. These sensors include, but are not limited to, temperature sensors, pressure sensors, smoke sensors, and water level sensors. It should be noted that the type of sensor can be adjusted according to actual conditions, and this invention does not impose further limitations in this regard. Furthermore, the sensors are not installed inside the multi-sensor acquisition box 200, but rather at multiple locations on the ship. The multi-sensor acquisition box 200 provides unified control for data acquisition from multiple sensors, and the acquired data is temporarily aggregated within the multi-sensor acquisition box 200.
[0055] In some embodiments of the present invention, the analog-to-digital converter 300 is an A / D converter; the A / D converter samples the ship's status data and ship damage data at preset time intervals and converts the analog signals into digital signals.
[0056] In the above embodiments, an A / D converter, abbreviated as ADC, generally refers to an electronic component that converts analog signals into digital signals. A typical analog-to-digital converter 300 converts an input voltage signal into an output digital signal. The acquired ship damage data is usually an analog signal, which is not conducive to subsequent transmission and storage. Therefore, it needs to be converted into a digital signal by an analog-to-digital converter 300 for storage. It should be noted that the analog-to-digital converter 300 needs to perform high-speed conversion, capable of rapidly converting large amounts of analog signal data into digital signal data in a short time. This invention does not further limit the specific model of the analog-to-digital converter 300, only requiring that it can perform rapid analog-to-digital conversion.
[0057] In some embodiments of the present invention, the wireless communication module 400 is at least one of a local area network module, a radio frequency communication module, and a microwave communication module.
[0058] In the above embodiments, the local area network module can achieve wireless transmission in areas covered by the local area network. Remote monitoring can be installed wherever there is local area network coverage. However, if the distance is relatively far, it will be limited by latency.
[0059] Radio frequency (RF) communication modules can transmit data over a network using RF technology. This is a development and extension of wireless communication technology. By connecting this technology with computer equipment, a shared network resource is formed. This also makes up for the shortcomings of wired local area networks, making the network coverage wider and achieving a network extension effect, thereby improving the efficiency of network use.
[0060] Microwave communication modules are one solution for data transmission in locations where cabling is difficult, such as those spanning several kilometers or even tens of kilometers. They employ frequency modulation (FM) or amplitude modulation (AM) to mount images onto a high-frequency carrier wave, converting them into high-frequency electromagnetic waves for transmission through the air. Their advantages include: low overall cost, more stable performance, and elimination of cabling and cable maintenance costs; dynamic real-time transmission of broadcast-quality images with good image clarity and complete real-time capability; flexible networking, good scalability, and plug-and-play functionality; and low maintenance costs.
[0061] This invention is illustrated using microwave transmission. This invention uses a microwave communication module to transmit digital signals of ship damage. It should be noted that before microwave transmission, the digital signals of ship damage need to be converted into microwave signals in order to achieve microwave transmission.
[0062] It is understood that the present invention can also use other wireless communication methods for data transmission, but when selecting other wireless transmission methods, it is necessary to first convert the digital signal of ship damage into a data format that can be transmitted by the corresponding transmission method.
[0063] In some embodiments of the present invention, the data storage module 500 includes a storage server 510 and a protective housing 520; the storage server 510 is disposed within the protective housing 520.
[0064] Storage server 510 is used to store the digital signals converted from ship status data and ship damage data, respectively;
[0065] The protective casing 520 is used to protect the storage server 510 from damage.
[0066] In the above embodiments, storage server 510 refers to a server designed for a specific purpose, and therefore its configuration varies. It may be a server with some additional storage or a server with a large storage capacity. Storage server 510 is typically a standalone unit. Sometimes they are designed as 4U rackmount units. Alternatively, they may consist of two enclosures—a storage unit and a nearby server.
[0067] The protective enclosure 520 needs to have good protective properties. It must be resistant to high temperature and high pressure, have good airtightness, and not be damaged in other extreme environments, so as to protect the data stored in the storage server 510 inside the protective enclosure 520 from being lost due to these extreme environments.
[0068] In some embodiments of the present invention, the comprehensive analysis unit 110 is at least one of an electronic computer, a microcomputer, and a single-chip microcomputer.
[0069] In the above embodiments, the integrated analysis unit 110 of the present invention is an electronic computer, which can receive the ship's status data collected from the multi-sensor acquisition box 200, and analyze the ship's operating status based on the ship's status data to determine whether the ship has experienced a collision accident.
[0070] It is understood that the comprehensive analysis unit 110 in this invention can also be selected from other devices or equipment with analytical capabilities, as long as they can analyze the ship's sailing status. This invention does not impose further restrictions on this.
[0071] In some embodiments of the present invention, the signal acquisition unit 210 includes at least one of radar, temperature sensor, pressure sensor, smoke sensor, and water level sensor.
[0072] In the above embodiments, the type of sensor can be adjusted according to the actual situation. The present invention does not impose further restrictions on this. It should be noted that the sensors used for data acquisition in the present invention should be able to perform high-frequency sampling in order to fully understand the multi-dimensional data of the ship.
[0073] In some embodiments of the present invention, the storage server 510 is at least one of a storage area network, network attached storage, and direct attached storage.
[0074] In the above embodiments, the Direct Attached Storage System (DAS) is also known as a server-centric storage architecture. Its characteristic is that the storage device is part of a general-purpose server, which also provides services such as application execution, video streaming, and databases. Data input and output are handled by the server, and data access is closely related to the operating system, file system, and service programs.
[0075] Network attached storage systems, or NAS, typically employ dedicated data servers. These servers no longer handle application services and are referred to as "thin servers." The data server connects to the application server via a local area network (LAN) interface. Because it uses common LAN data transmission protocols such as NFS and CIFS, it can share data between heterogeneous servers.
[0076] Storage Area Network (SAN) uses Fibre Channel, a high-speed data connection channel, to connect servers and storage systems. Structurally, servers and data storage systems are independent of each other. Connecting devices to hubs or switches facilitates system scalability.
[0077] Please see Figure 2 , Figure 2 The above is a flowchart illustrating an embodiment of the multi-sensor wireless acquisition and transmission method for ship collision data provided by the present invention. In a second aspect, the present invention also provides a multi-sensor wireless acquisition and transmission method for ship collision data, based on the multi-sensor wireless acquisition and transmission system for ship collision data as described in any of the above implementations, comprising:
[0078] S201. Real-time acquisition of ship's surrounding environment data, ship acceleration data, and ship vibration data through high-frequency sampling;
[0079] S202. Determine whether the distance between the ship and surrounding obstacles exceeds the safe distance based on the data of the ship's surrounding environment;
[0080] S203. When the distance between the ship and surrounding obstacles exceeds the safe distance, determine whether the degree of change in the ship's acceleration exceeds the preset threshold based on the ship's acceleration data.
[0081] S204. When the degree of change in the ship's acceleration exceeds the preset threshold, determine whether the ship's vibration exceeds the preset amplitude based on the ship's vibration data.
[0082] S205. When the ship's vibration exceeds the preset amplitude, a control signal is sent to mark the ship's state data within the preset time range as ship damage data.
[0083] S206. Store the ship's status data and ship damage data on different servers.
[0084] In the above embodiment, the multi-sensor acquisition box 200 first collects data during the ship's navigation process. This data includes data on the ship's surrounding environment, ship acceleration data, and ship vibration data. It is understood that the ship's surrounding environment data can be obtained by radar scanning for obstacles within a certain range around the ship, the ship acceleration data can be measured by an acceleration sensor, and the ship vibration data can be measured by a vibration sensor.
[0085] The safety distance can be set according to the actual situation. Determining whether the distance between the ship and surrounding obstacles exceeds the safety distance can help determine whether the ship has collided with the surrounding obstacles. It should be noted that the safety distance in this invention can be set according to the actual situation, and this invention does not impose any further restrictions on it.
[0086] When the distance between a vessel and surrounding obstacles exceeds a safe distance, a collision may have occurred. Further analysis of the vessel's acceleration data is needed. It is also necessary to consider whether the helmsman altered the vessel's acceleration. If, in addition to helmsman intervention, an external force causes a sudden change in the vessel's acceleration, a collision is preliminarily identified. It should be noted that the preset thresholds in this invention can be set according to actual conditions, and this invention does not impose further limitations on this.
[0087] When the change in the ship's acceleration exceeds a preset threshold, further analysis of the ship's vibration data is performed. If the ship's vibration exceeds a preset amplitude, a collision is identified, and a control signal is sent to mark the ship's state data within a preset time range as ship damage data. It should be noted that the preset amplitude in this invention can be set according to actual conditions, and this invention does not impose further limitations on it.
[0088] In summary, this embodiment provides a multi-sensor wireless acquisition and transmission system and method for ship collision data. The system includes a collision detection module, a multi-sensor acquisition box, an analog-to-digital converter (ADC), a wireless communication module, and a data storage module. The multi-sensor acquisition box is connected to both the collision detection module and the ADC via the wireless communication module. The ADC is connected to the data storage module. The collision detection module determines whether an accident has occurred based on the ship's status data and sends a control signal to the multi-sensor acquisition box when an accident occurs. The multi-sensor acquisition box samples the ship's status data at high frequency, marks ship damage data in the status data according to the control signal, and sends the ship's status data and damage data to the ADC. The ADC converts the ship's status data and damage data into digital signals and sends the digital signals to the data storage module. The data storage module receives the digital signals and stores them in a server. This invention provides a multi-sensor wireless acquisition and transmission system and method for ship collision data. It uses a collision detection module to determine whether a collision has occurred. When a collision occurs, the system uses control signals to separately mark the ship's damage data. The system then transmits the ship's status data and damage data via a wireless communication module, and stores them separately in a data storage module. This overcomes the limitations of existing technologies where data cannot be collected and transmitted after a collision, effectively collecting and storing ship operational data. Furthermore, it solves the problem of high workload and difficulty in repairing and replacing wired transmission lines when they fail, reducing maintenance costs and complexity.
[0089] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.

10. A multi-sensor wireless acquisition and transmission method for ship collision data, based on the multi-sensor wireless acquisition and transmission system for ship collision data as described in any one of claims 1-9, characterized in that, include: Real-time data on the ship's surrounding environment, ship acceleration, and ship vibration are acquired through high-frequency sampling. Based on the data on the ship's surrounding environment, determine whether the distance between the ship and surrounding obstacles exceeds the safe distance; When the distance between the ship and surrounding obstacles exceeds the safe distance, the ship's acceleration change is determined based on the ship's acceleration data to see if it exceeds a preset threshold. When the change in the ship's acceleration exceeds a preset threshold, the ship's vibration is determined to be above a preset amplitude based on the ship's vibration data. When the ship's vibration exceeds the preset amplitude, a control signal is sent to mark the ship's status data within the preset time range as ship damage data; The ship's status data and the ship's damage data are stored on different servers.
