[0002] With the continuous development of cross-domain communication technology, various application scenarios have put forward higher requirements for the reliability, cost-effectiveness, and the ability to adapt to complex environments of communication systems. Traditional cross-domain communication systems often face problems such as high cost, poor reliability, and difficult maintenance, especially in complex scenarios such as water environments, where these problems are particularly prominent.

[0003] For example, some communication systems have high overall costs due to complex designs and expensive components; at the same time, due to the lack of effective redundancy design and fault response mechanisms, once the main communication module fails, the entire device will lose its communication ability, seriously affecting the execution of tasks.

Detailed Implementation Manner

[0015] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0016] Please refer to Figures 1 - 3 , the present invention provides a technical solution for a low-cost cross-domain communication system, including: Floating body 1: It adopts a circular ring shape, with a circumferential size less than 1M, and is coated with gray paint to enhance its concealment and durability in the water environment.

[0017] Housing assembly 2: It is arranged in the middle of the floating body 1 to shield and protect the main module 3 and the sub-module 4. The housing assembly 2 includes a metal frame 21, a lower housing 23, an upper housing 22 and a glass float 24. The metal frame 21 is fixedly connected to the floating body 1. Both the lower housing 23 and the upper housing 22 are hemispherical structures and are coated with gray paint. The main module 3 and the sub-module 4 are both installed inside the glass float 24, and the glass float 24 is fixed inside the lower housing 23. The middle of the upper housing 22 is hollowed out, covering the glass float 24 and fixedly connected to the lower housing 23.

[0018] Main module 3: It includes a Tiantong satellite communication and a first positioning antenna, a Tiantong main control module, and a first underwater acoustic communication transducer 31. The main module 3 preferentially executes communication tasks to ensure the efficiency and stability of communication. At the beginning of the communication task, the main module 3 preferentially executes the communication task, establishes a connection with the remote node through the Tiantong satellite communication antenna, and sends communication data; at the same time, the Tiantong main control module monitors the communication process in real time to ensure the correct transmission and reception of data.

[0019] Sub-module 4: It includes a Beidou satellite communication and a second positioning antenna, a Beidou main control module, and a second underwater acoustic communication transducer 41. During the execution of the communication task, the sub-module 4 is in the standby mode; once the main module 3 fails, the processing unit will immediately switch the sub-module 4 to take over the communication task, establish a connection with the remote node through the Beidou satellite communication antenna, and send the unfinished communication data. At the same time, the Beidou main control module will take over the work of the Tiantong main control module, continue to monitor the communication process and ensure the correct transmission and reception of data.

[0020] Furthermore, an asynchronous communication between the main module 3 and the sub-module 4 is realized by adopting a message queue and an event mechanism. The specific steps include: S1: Set message rules, define message types and priorities to ensure that the main module 3 and the sub-module 4 can accurately understand each other. Message types include but are not limited to many interactive messages such as communication cooperation, communication response, and fault notification, etc., among which the fault notification has the highest priority among all. The established processing unit determines the message type.

[0021] S2: Establish a message channel: In the processing unit, message queues corresponding to the main module 3 and the secondary module 4 are set up as channels for message type transmission. The queue is managed according to the "First In First Out" (FIFO) principle to ensure that messages are processed in order, thereby ensuring the reliability and sequentiality of communication.

[0022] S3: Set up an automatic response mechanism: An event-triggered mechanism is designed so that fault notifications (such as main module 3 failure, communication interruption) can automatically trigger corresponding responses. For example, when the processing unit detects that the message queue of the main module 3 contains a message type of fault notification, it will automatically switch to the secondary module 4 to take over the task to ensure that the task is not interrupted.

[0023] Through the close cooperation between the main module 3 and the secondary module 4, a highly reliable design is achieved. The main module 3 is responsible for the main communication tasks, while the processing unit monitors the working status of the main module 3 in real time. Once the main module 3 fails, the secondary module 4 will immediately take over its tasks to ensure the continuity of communication.

[0024] Both the Tiantong main control module and the Beidou main control module are protected by shielding encapsulation. A metal shielding cover 5 is used to reduce external electromagnetic interference and improve communication stability.

[0025] An interface and space are reserved at the lower part of the housing assembly 2, allowing users to adjust the number of the first underwater acoustic communication transducer and / or the second underwater acoustic communication transducer 41 according to their needs and expand the communication program storage, improving the flexibility and scalability of the device.

[0026] Battery module: A rechargeable lithium battery with fast charging function is adopted to improve the battery life and usage convenience of the device.

[0027] Furthermore, a power monitoring module is integrated in the device to monitor the battery power and the power consumption of each module (main module 3, secondary module 4) in real time; and according to the monitoring results, the power supply of the main module 3 and the secondary module 4 is dynamically adjusted. In one embodiment, multiple energy-saving modes are preset, such as normal mode, low power consumption mode, standby mode, etc. Users can select a suitable mode according to actual needs; for example, in the low power consumption mode, the device only maintains basic communication and monitoring functions, significantly reducing energy consumption; in the standby mode, except for necessary maintenance tasks, the device is almost completely turned off to save power to the maximum extent. Preferably, the processing unit is circuit-connected to the power monitoring module, and a wake-up mechanism is filled in the processing unit. When the device detects a specific event (such as main module 3 failure), it automatically wakes up from the low power consumption mode or standby mode to the normal mode.

[0028] By presetting multiple energy-saving modes, the energy consumption of the device can be significantly reduced, the battery life can be extended, and the overall energy efficiency can be improved.

[0029] An interface is reserved below the glass float 24 to enable long-distance debugging through RS422 and a tiny 8-core interface, facilitating maintenance and upgrade by users.
