Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of and meet probability by the meeting of calculating between the boats and ships in the setting range, meeting early-warning conditions according to the meeting of setting screens, and sort from small to large according to the meeting time of meeting, carry out the collision prevention early warning then, more effectively avoid the collision of boats and ships, guarantee the boats and ships intelligence collision prevention prior-warning device of navigation safety.
The technical scheme that the utility model adopted is: a kind of boats and ships intelligence collision prevention prior-warning device, include CPU (central processing unit), man-machine interaction unit and loudspeaker, described CPU (central processing unit) receives this ship information data through global position system transmitted by first data-interface respectively, receive other ship information data by second data-interface, connect loudspeaker by speaker interface; Described CPU (central processing unit) also connects man-machine interaction unit.
Described man-machine interaction unit includes the keypad that is used to show the LCDs of CPU (central processing unit) data processed result and is used for imposing a condition to the CPU (central processing unit) input.
Described global position system comprises the GPS global positioning system Beidou satellite navigation and positioning system of unifying.
Described CPU (central processing unit) comprises embedded microprocessor, described embedded microprocessor is by the external SDRAM of Memory Controller Hub of itself, by the external NandFlash of Nand Flash controller of itself, the UART interface of employing itself is as first data-interface and second data-interface of transmission this ship information data and other ship information data, IIS interface by itself connects loudspeaker via the speaker interface that the Audio Processing chip constitutes, by the external LCDs of lcd controller of itself, by its GPIO mouth external connection keyboard.
Boats and ships intelligence collision prevention prior-warning device of the present utility model, gather the boats and ships information data by embedded microprocessor, and probability is met in the meeting between the boats and ships in the calculating setting range, meeting early-warning conditions according to the meeting of setting screens, and sort from small to large according to the meeting time of meeting, the route that mark may be met on man-machine interface sends the vision early warning on man-machine interface then, by the loudspeaker early warning of sounding, effectively raise the accuracy of anti-collision warning.
