Accompanying drawing explanation
Fig. 1 is the structural representation of intelligent maritime radio telephone of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As it is shown in figure 1, the intelligent maritime radio telephone of the present invention, switch switch 6, first antenna 21 and the second antenna 22 including modem 1, microprocessor 2, TDMA transmitter 3, TDMA receiver 4, radio receiver 5, RX/TX；The input of TDMA transmitter 3, TDMA receiver 4 outfan are all connected with modem 1.Modem 1 is also connected with microprocessor 2；The outfan of TDMA transmitter 3 is connected with RX/TX switching switch 6, and TDMA transmitter 3 is also associated with a speech signal amplifier 9.RX/TX switching switch 6 is also connected with radio receiver 5, and radio receiver 5 is also associated with a speaker 12.Described first antenna 21 is connected with the input of TDMA receiver 4, and described second antenna 22 is located on RX/TX switching switch 6；Further, first antenna 21 can be passed through a band filter 11 and be connected with receiving allotter 7, and the second antenna 22 can pass through a low pass filter 10 and be connected with RX/TX switching switch 6.TDMA receiver 4 is additionally operable to poll search idle channels；Microprocessor 2 is additionally operable to that the communication channel of radio receiver 5 is adjusted to the idle channels that TDMA receiver 4 retrieves and converses.Specifically, described TDMA transmitter 3 carries out initiating calling: frame emission message is sent out by data channel, and wherein frame emission message includes called object information, calls corresponding call type and the communication channel specified；Wherein, the described communication channel specified is the idle channels searched by TDMA receiver 4.Described TDMA receiver 4 is received calling: interception data passage, receive and parse through external frame emission message, when showing that this frame emission message call object is in non-talking state for self and self, the communication channel that radio receiver 5 is adjusted to specified by this frame emission message is conversed；Otherwise refuse call request.The TDMA receiver 4 of other device by ship or bank equipments on stage is sent datagram (i.e. described frame emission message) by data channel by the TDMA transmitter 3 of this ship equipment, the TDMA receiver 4 of this ship equipment also receives the data message of the TDMA transmitter 3 of other device by ship or bank equipments on stage, when determining that call set up by needs, automatically the communication channel of radio receiver 5 is adjusted to appointed communication channel (communication channel does not imply that data channel above) thus carrying out dialogue again, and is not take up common frequency channel.The information of called object can adopt concrete address code, it would however also be possible to employ condition value judges, concrete coded system can adopt various existing coded method to realize, and owing to not being the improvement of the present invention, does not repeat them here.
Further, described TDMA receiver 4 is additionally operable to: set the priority level of call type corresponding to calling, for instance for the superlative degree, ordinary call call is lowermost level to the priority level of maritime affairs urgent call；When receiving frame emission message that call object is self and self being in talking state, the relatively priority level calling corresponding call type priority level and the call type of oneself state of this frame emission message, when the call type priority level that the calling of this frame emission message is corresponding is higher than oneself state, interrupt existing talking state, and jump to this communication channel specified by frame emission message and converse；Otherwise refuse call request.Such as when the machine is carrying out ordinary call call, and now TDMA receiver 4 receives the call request of maritime affairs urgent call, then interrupt existing call, and the channel specified by the call request communication channel of transceiving being adjusted to maritime affairs urgent call is conversed.It should be noted that, by to " information of called object ", in a different manner or condition is encoded and comparison, multiple different method of calling can be obtained, thus multiple call type can be obtained, every ship such as, arranges an assembly of the invention, every table apparatus can have an address code that will not repeat with other equipment, confirms conversation object directly and accurately by this unique address code；Again such as, a group is had the ship of particular kind of relationship, it is possible to arrange one and group busy code, thus realizing grouping busy to the ship group of this particular kind of relationship；When such as there are burst weather conditions again, the whole ships in specific region are all sent alarm by base station, it is possible to by carrying out the determination of called object with positional informationes such as longitudes and latitudes.But; the determination (the various of other can be had precedence over still urgent call in such as actual enforcement to exhale) of the priority level of these type of calls miscellaneous; belong to the category of artificial regulation; it it not the consideration category of the present invention; which kind of, no matter with different priority level sequence, should be included within protection scope of the present invention.Actual enforcement sets priority level according to actual needs, but, cause playing the effect of the present invention for not meeting the setting (such as the priority level of common call being set higher than maritime affairs urgent call) of convention, cause improving nevigation safety, be not necessarily to be construed that the present invention cannot realize technique effect.It is desirable to provide the technical scheme of a kind of equipment that can realize above-mentioned functions, to ensure that call is unimpeded, improve nevigation safety, the above-mentioned setting not meeting convention belongs to the misapplication to technical solution of the present invention.
Present invention additionally comprises GPS module 13；Described GPS module 13 is connected with microprocessor 2；TDMA transmitter 3 is additionally operable to send the AIS message comprising GPS geography information；TDMA receiver 4 is additionally operable to receive and parse through AIS message；Make the present invention can receive more data, provide basis for analyzing, process various situation more intelligently.Microprocessor 2 is additionally operable to: arrange distance reference value, is calculated the actual range of other ships by the AIS message received by TDMA receiver 4, sends alarm when actual range is less than distance reference value.Specifically, present invention additionally comprises the display screen 8 being connected with microprocessor 2；Display screen 8 is for showing the AIS message received by TDMA receiver 4 data after resolving.
Signal for ensureing data channel receives smooth and easy, present invention additionally comprises reception allotter 10；The quantity of described TDMA receiver 4 is more than one；The outfan of multiple TDMA receivers 4 is all connected with modem 1, and the input of multiple TDMA receivers 4 is all connected with reception allotter 10；First antenna 21 is connected with TDMA receiver 4 by receiving allotter 10.Consider cost and actual demand, it is preferred to two TDMA receivers 4.
