In the embodiment of the invention, after the data to be transmitted is subjected to slice coding, the data subjected to slice coding can be transmitted to the shipborne gateway through at least one communication channel, and the shipborne gateway can assemble and restore the received slice packets of each communication channel to obtain the early warning information and the meteorological information and further output the early warning information and the meteorological information to shipborne terminal equipment.
As an alternative embodiment, the shipboard terminal device 305 is further configured to send request information to the onshore control system 301 in response to detecting the third marine communication command, where the request information at least includes an inquiry request, a navigation request, and an alarm request; the onshore control system 301 is further configured to search for the target content and return the target content to the shipboard terminal device 305 in the case that the request information is an inquiry request; under the condition that the request information is a navigation request, generating a navigation line based on the position of the shipboard terminal device 305 and the current meteorological condition, and returning the navigation line to the shipboard terminal device 305; in the case where the request information is an alarm request, the alarm request is transmitted to a specified management system, and a prompt message that the alarm request has been received is returned to the on-board terminal device 305.
In the embodiment of the invention, the shipboard terminal equipment can also send request information to the shore control system, and the shore control system can respond to the request information and execute corresponding operation so as to realize data transmission interaction between the shipboard terminal equipment and the shore control system. The request information may include a query request, a navigation request, and an alert request. The query request is used for querying related resources, and the query request may carry a query condition, so that the onshore control system queries the related resources based on the query condition. The navigation request is used for requesting to acquire a navigation path, and the navigation path can be generated by an onshore control system in combination with a weather environment at sea. The alert request is used to request handling of an emergency event aboard the vessel, e.g., the alert request may be used for SOS distress. The shore control system can respond to the query request, search for the target content, and return the target content to the shipboard terminal equipment. Alternatively, a navigation route may be generated based on the position and destination position of the on-board terminal device and the current weather condition in response to the navigation request, and returned to the on-board terminal device. Still alternatively, the alarm request may be responded to and transmitted to a designated management system, such as transmitting an SOS distress signal to a system used by the relevant management department, so that the relevant management department can handle the situation in time. And the shore control system can also return prompt information of the received alarm request to the shipboard terminal equipment so that the shipboard terminal equipment can know the information transmission condition in time.
As an optional implementation manner, the onshore control system 301 is further configured to determine an optimal path based on information attributes of information to be transmitted and channel attributes of each communication channel in the case of transmitting the information through at least one communication channel 303, where the information attributes at least include information urgency and information content size, and the channel attributes at least include channel speed and channel cost; and transmitting the information by using the optimal path.
In the embodiment of the present invention, the optimal path for transmitting information through a communication channel may be determined according to an information attribute of the information to be transmitted and a channel attribute of the communication channel, where the information attribute may include, but is not limited to, an information urgency attribute, an information transmission requirement attribute, an information type attribute, and the like, and the channel attribute may include, but is not limited to, a channel transmission speed attribute, a channel transmission cost attribute, a channel transmission characteristic attribute, and the like.
For example, if the information to be transmitted is the warning information, the information transmission requirement attribute is speed priority, and the generated optimal path adopts multi-path transmission. If the information to be transmitted is meteorological information, particularly information such as a marine radar chart and a wind chart, the information type attribute is a multimedia information type, the generated optimal path is mainly an aerospace satellite or mobile communication, and information transmission is carried out with other communication channels as assistance. If the information to be transmitted is observation data, the requirements on data real-time performance and data instructions are not high, and the optimal path can be the path with the lowest cost. And the return process of the observation data is that the ship-borne weather observation station regularly collects and returns the observation data, so that the observation data can be used for verifying the communication heartbeat of the marine communication link, and the communication cost can be reduced. Or, if the information to be transmitted is an SOS distress signal, the emergency degree is considered to be high, and reserved single-channel resources such as a Beidou satellite can be adopted to carry out rapid data transmission by utilizing the Beidou satellite.
