Fig. 2 is the structured flowchart setting up ship control management system based on the utility model networking.
In figure: 1. main frame, 2. built-in power, 3.VHF antenna, 4.GPS antenna, 5. wireless radio frequency modules, 50.VHF transmitter, 51.DMA receiver, 52.DSC receiver, 6.GPS receiver, 7. a key alarm module, 8. gyro compass, 9. head center's control system, 10. building berth terminal, 11.Internet network, 12. terminal base station systems.
Below by way of embodiment, the utility model will be further described.
See figures.1.and.2, the portable ship automatic identification system of one of the present utility model, i.e. AIS system, includes main frame 1, built-in power 2, VHF antenna 3, gps antenna 4 and can be communicatively coupled to the wireless radio frequency modules 5 of main frame 1, GPS 6 and a key alarm module 7.Described wireless radio frequency modules 5 includes a VHF transmitter 50, two DMA receivers 51 and a DSC receiver 52 that can be communicatively coupled to main frame 1.Described gps antenna 4 is connected to GPS 6, in order to realize GPS location.Described VHF antenna 3 is connected to VHF transmitter 50, VHF transmitter 50 and is operated in 156.025-162.025MHz frequency range.Described main frame 1 can communicate to connect gyro compass 8.
Low for meeting spitkit astronomical cycle level height; guarantee equipment can receive normally to security-related short message; two DMA receivers 51 of equipment adopt high sensitivity to design; circuit adopts high-frequency amplifier circuit and the common mode mixting circuit of two-stage high-gain low-noise; cooperation ± 3.75KHz narrow-band crystal filter; to improve output signal-to-noise ratio, ensure that the Packet Error Ratio under high sensitivity meets the demands.
The high-precision compensation crystal of system employing ± 1.5PPm shakes as transmitting-receiving owner, crystal oscillator 19.200MHz, and transceiver operational frequency is up to 162.025MHz, such equipment from primary frequency error for≤1KHz is increased to≤500Hz, improves frequency stability.
See figures.1.and.2, the utility model can be installed on small fishing vessel, when system switches on power, small fishing vessel is started working in operation sea area, AIS system coordinates global positioning system to unify gyro compass 8, by the accommodation of this ship, course, ship's speed, the navigation associated dynamic information such as course made good and name of vessel, identification code, ship type, catchword waits boats and ships static data, and drauht, port of destination and species of freighting etc. and security-related voyage information use VHF channel to send to the boats and ships of Its Adjacent Waters and the seashore station by VHF transmitter 50, receive the quiet of periphery boats and ships and the seashore station simultaneously, multidate information and voyage information, navigation data exchange system is set up between this ship and other boats and ships and the seashore station, the dynamic static information of all boats and ships in neighbouring sea can be grasped in time, be able to converse mutually at once coordination, be conducive to small fishing vessel when operation and the boats and ships of periphery effectively dodge, the generation of minimizing accident.Meanwhile, as occur dangerous situation or equipment overboard time, send the emergency of dangerous situation content from trend periphery boats and ships or the seashore station in time by a key warning function.
Portable ship automatic identification system of the present utility model carries out networking by systematicness, sets up ship control management system.Head center's control system 9 can directly control ultrashort wave (USW) individually by parametric controller with serial ports 232 communication and send instruction to control building berth terminal 10 to realize monitoring and scheduling and two-way call etc. at common channel, also can control each terminal base station system 12 by Internet network 11, make it send instruction to control building berth terminal 10 to realize monitoring and broadcast; Each terminal base station system 12 directly controls radio station by central platform controller and sends instruction to control building berth terminal 10 to realize monitoring and scheduling at common channel, and building berth terminal 10 is once the instruction ultrashort wave (USW) communication modes receiving center passes through namely automatically to respond.Building berth terminal 10 gathers GPS locating information and relevant information sends information with ultrashort wave (USW) communication modes by common channel, be sent to head center's control system 9 database by Internet network 11 after each terminal base station system 12 receives information, then on electronic chart screen, show its orientation and identification code.All transmit exchange position information by data between daily building berth and building berth or between the seashore station and building berth, control without the need to central platform.
A kind of portable ship automatic identification system of the present utility model equally can self-organizing system when not having the seashore station, carries out exchanges data with periphery boats and ships.The boats and ships of open waters compare less, and the general data near boats and ships as main object ship, can be carried out voice message by nearest boats and ships by AIS system, and prompting object is convenient to dodging and communicating with each other between boats and ships.Even if once dodge improper, when causing two ships to crash, the data due to opponent vessel are kept in AIS system automatically, and therefore scene can confirm that collision is true and understand damaed cordition etc. at once, without the need to first inquiring the other side's name of vessel again, the master datas such as shipping company's title.In understanding accident conditions and investigation phase, because the aeronautical data of opponent vessel can be preserved by AIS system automatically, both sides' is dynamically perfectly clear, and accident responsibility more easily judges.
Above are only an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
