Accompanying drawing explanation
Fig. 1 is the wireless telephonic structural representations of the present invention's intelligence maritime affairs.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, intelligent maritime affairs radio telephone of the present invention, comprises modulator-demodulator 1, microprocessor 2, TDMA transmitter 3, TDMA receiver 4, radio receiver 5, RX/TX diverter switch 6, the first antenna 21 and the second antenna 22; The input of TDMA transmitter 3, TDMA receiver 4 outputs are all connected with modulator-demodulator 1.Modulator-demodulator 1 is also connected with microprocessor 2; The output of TDMA transmitter 3 is connected with RX/TX diverter switch 6, and TDMA transmitter 3 is also connected with a speech signal amplifier 9.RX/TX diverter switch 6 is also connected with radio receiver 5, and radio receiver 5 is also connected with a loud speaker 12.Described the first antenna 21 is connected with the input of TDMA receiver 4, and described the second antenna 22 is located in RX/TX diverter switch 6; Further, the first antenna 21 can be connected with reception distributor 7 by a band pass filter 11, and the second antenna 22 can be connected with RX/TX diverter switch 6 by a low pass filter 10.TDMA receiver 4 is also for poll search idle channels; Microprocessor 2 is also conversed for the communication channel of radio receiver 5 being adjusted to the idle channels that TDMA receiver 4 retrieves.Particularly, described TDMA transmitter 3 makes a call: frame emission message is outwards sent by data channel, and wherein frame emission message comprises called object information, calls out corresponding call type and the communication channel of appointment; Wherein, the communication channel of described appointment is the idle channels searching by TDMA receiver 4.Described TDMA receiver 4 carries out receipt of call: interception data passage, receive and resolve external frame emission message, when showing that this frame emission message call object, for self and self during in non-talking state, is adjusted to the specified communication channel of this frame emission message radio receiver 5 to converse; Otherwise refusal call request.The TDMA transmitter 3 of this ship equipment by data channel to the TDMA receiver 4 of other device by ship or bank equipments on stage send datagram (being described frame emission message), 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 needs are set up call, automatically the communication channel of radio receiver 5 is adjusted to appointed communication channel (communication channel does not refer to data channel above) again thus carry out dialogue, and do not take common frequency channel.The information of called object can adopt concrete address code, also can adopt condition value to judge, concrete coded system can adopt various existing coding methods to realize, and owing to not being improvement of the present invention, does not repeat them here.
Further, described TDMA receiver 4 also for: set to call out the priority level of corresponding call type, for example the priority level of maritime affairs urgent call for superlative degree ordinary call call be lowermost level; When receiving the frame emission message that call object is self and self is during in talking state, the priority level of the call type priority level of the calling correspondence of this frame emission message and the call type of oneself state relatively, when the call type priority level of the calling correspondence of this frame emission message is during higher than oneself state, interrupt existing talking state, and jump to the specified communication channel of this frame emission message and converse; Otherwise refusal call request.For example, when the machine is being carried out ordinary call call, and now TDMA receiver 4 is received the call request of maritime affairs urgent call, interrupt existing call, and the specified channel of call request that the communication channel of transceiving is 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 encode and compare, can obtain multiple different method of calling, thereby can obtain multiple call type, a device of the present invention is for example set on every ship, every table apparatus can have an address code that can not repeat with other equipment, by this unique address code, confirms directly and accurately the object of conversing; Again for example, a group is had to the ship of particular kind of relationship, can arrange one and group busy code, thereby the ship group of this particular kind of relationship is realized and being grouied busy; While for example there are burst weather conditions again, base station all gives the alarm to the whole ships in specific region, can be by carry out determining of called object with positional informations such as longitudes and latitudes.Yet; the determining of the priority level of these type of calls miscellaneous (for example in actual enforcement can with or urgent call has precedence over the various of other and exhales); the category that belongs to artificial regulation; it not consideration category of the present invention; which kind of no matter with different priority level, sort, within all should being included in protection scope of the present invention.In actual enforcement, set according to actual needs priority level, but, for example, for meeting the setting (priority level of common call being made as higher than maritime affairs urgent call) of convention, do not cause bringing into play effect of the present invention, cause improving nevigation safety, all should not be construed as the present invention and cannot realize technique effect.The present invention aims to provide a kind of technical scheme that can realize the equipment of above-mentioned functions, and to guarantee unimpeded, the raising nevigation safety of conversing, the above-mentioned setting that does not meet convention belongs to the misapplication to technical solution of the present invention.
The present invention also comprises GPS module 13; Described GPS module 13 is connected with microprocessor 2; TDMA transmitter 3 is also for sending the AIS message that comprises GPS geography information; TDMA receiver 4 is also for receiving and resolve AIS message; Make the present invention can receive more data, for analyzing more intelligently, process various situations, provide basis.Microprocessor 2 also for: distance reference value is set, by the AIS message of being received by TDMA receiver 4, calculates the actual range of other ships, when actual range is less than distance reference value, give the alarm.Particularly, the present invention also comprises the display screen 8 being connected with microprocessor 2; Display screen 8 is for showing the AIS message that received by TDMA receiver 4 data after resolving.
Smooth and easy for guaranteeing that the signal of data channel receives, the present invention also comprises reception distributor 10; The quantity of described TDMA receiver 4 is more than one; The output of a plurality of TDMA receivers 4 is all connected with modulator-demodulator 1, and the input of a plurality of TDMA receivers 4 is all connected with reception distributor 10; The first antenna 21 is connected with TDMA receiver 4 by receiving distributor 10.Consider cost and actual demand, be preferably two TDMA receivers 4.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
