Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further so that those skilled in the art can better understand the present invention and implementing, but the embodiment that lifts not conduct to qualification of the present invention.
Shipborne terminal alarm method of the present invention is; Alarm terminal on the ship in distress generates warning message; And send command centre via satellite to, after command centre receives warning message, send logical broadcast message all Shipborne terminals (or claiming the subordinate terminal) to subordinate through big-dipper satellite; Place, the subordinate terminal boats and ships that receive logical broadcast message go to rescue or ignore message according to the rescue ability decision of oneself.
As shown in Figure 3, an embodiment of Shipborne terminal alarm method of the present invention comprises the steps:
Step 1, boats and ships generation emergency condition;
Step 2, crewman press the terminal alarm button, trigger alarm terminal;
Step 3, alarm terminal are uploaded warning message to big-dipper satellite;
Step 4, big-dipper satellite send to command centre with warning message;
Step 4, command centre are to the logical broadcast message of Big Dipper satellite transmission warning message;
Step 5, big-dipper satellite will lead to that broadcast message is logical to be broadcast to each subordinate terminal;
Step 6, receive place, each subordinate terminal boats and ships of warning message, when oneself has rescue ability, go to rescue;
Step 7, alarm procedure finish.
Used big-dipper satellite in the present embodiment.In other embodiments, also can use other to have the satellite of communication function.Those skilled in the art know that as shown in Figure 4, when communicating through big-dipper satellite, for each Shipborne terminal all sets Big Dipper card, Big Dipper card is divided into commander's card and subordinate's card.
On Shipborne terminal equipment, all can be furnished with subordinate's card; The terminal reports a warning message (command centre can place any Zhangbei County bucket stick into row reception) with point-to-point mode to the center through subordinate's card when reporting to the police; Command centre commands card to send the logical alarming information of reporting to its all subordinate's card through the Big Dipper of command centre's configuration after receiving warning message.
In the warning message that alarm terminal is uploaded, comprised positional information, ship name and the type of alarm etc. of ship in distress, also comprised positional information, ship name and the type of alarm information of ship in distress in the logical broadcast message that command centre sends.Subordinate terminal on other boats and ships is after receiving logical broadcast message; According to the positional information of the ship in distress that carries in the logical broadcast message and the positional information of self; Calculate and ship in distress between distance, if this distance is less than a predeterminable range (for example 60 nautical miles), and shows and lead to the information of broadcasting; If greater than predeterminable range, then explanation does not have rescue ability, can ignore logical broadcast message and will not show.
Certainly; Also can be behind command centre's logical report alarming information; According to the positional information of each Shipborne terminal judge which boats and ships apart from ship in distress in 60 nautical miles; Command centre sends the Shipborne terminal of warning message to these boats and ships, and the Shipborne terminal of these boats and ships receives display alarm information behind the warning message, goes to rescue by these boats and ships.
In addition, because different dangerous situations is different to the rate request of rescue, because the rescue ability of boats and ships also can be different on every side.Therefore, can dispose a predeterminable range for each type of alarm.Corresponding predeterminable range is chosen according to the type of alarm of carrying in the logical broadcast message in the subordinate terminal, and the distance between self and the ship in distress compares, and has judged whether rescue ability.
