Embodiment
Be structural representation of the present invention as Figure 1-3, owing to adopting multi-point touch high definition screen, thus be designed to horse-saddle, thus screen is played to certain protection.Earphone 1(loud speaker) be arranged at handheld terminal upper end, the design of circular arc convex shaped.Antennal interface adopts 360 degree rotary foldings, and earphone jack 2 designs are sealing with rubber stopper near antenna root, and power source charges Interface design is in bottom, and navascreen 3 is arranged on the middle part of handheld terminal, and the below of this navascreen is provided with digital keys 4.
Regional satellite communication navigation intercommunication handheld terminal comprises: intercommunication module, for the voice communication between user; Positioning navigation module, positions for the position to user; SMS module, for carrying out transfer of data by short message.
Described intercommunication module comprises:
Intercommunication function module: handheld terminal possesses the communication function of similar common intercom.But be with intercom difference in the use: sound is not the transmitting same period, but first records, and carries out message transmission when recording.The time that voice messaging sends is recording time six times.Screen display during transmission " in voice transmission ".The voice messaging that the other side sends shows in receiving course: " in phonetic incepting ".
When voice recording form is 600bps, transmission rate while being locked in 100bps, because the voice transmitting-receiving time is six times of voice recording time.In order to meet people's use habit, the specific adopted wall scroll voice recording time is the longest must not surpass for 10 seconds.
According to the longest 10 seconds, complete voice and send, and within the longest 10 seconds, complete one time phonetic incepting, realizing once two-way intercommunication needs duration 2 minutes.
Sound recording module, when user presses the PPT button of handheld terminal, terminal starts to record, and when user discharges PPT button, records end.If the user key-press time is while surpassing for 10 second, system was automatically cut off and is recorded then carry out next step operation in the time of 10 seconds.
Analog-to-digital conversion module, the voice to be sent of recording will carry out analog-to-digital conversion, the analog signal of recording is converted to 600bps(512bps) digital signal, it within every 0.5 second, is a minimum recording unit, being 300bps(256bps) continuous 20 minimum recording units are the maximum recording group of single, so that the later stage is carried out the transmission of short message information.
Message sending module, handheld terminal can be adjusted transmission rate automatically according to antenna gain, and when dual-mode antenna is 0.4 meter of parabolic antenna, transmission rate is 600bps.When adopting whip antenna, transmission rate is reduced to 100bps speed, and the time span that transmits message approximates six times of voice time span.When handheld terminal is when blocking, the minimum 5bps that is reduced to.Transmission rate below 100bps, is only used for calling out to start.
Message receiver module, the reception of voice message is launched together, speed is automatically adjusted and is locked.The information of sending as satellite is still 100bps, after receiving, is carrying out digital-to-analogue conversion.
D/A converter module, handheld terminal carries out digital-to-analogue conversion by the voice message information receiving, and then automatically switches into speech play pattern.By loud speaker or earphone, play.
Historical summary retrieval and repeat playing functional module, common simulation intercom is real-time, historical information can not realize retrieval and reset.SMI can realize voice and reset and information retrieval.
Individual calling, group calling module, handheld terminal can be realized a handheld terminal and call out an other handheld terminal, car-mounted terminal.Also can realize and call out one group of terminal.
Described positioning navigation module comprises:
Locating information passback module, handheld terminal design Yi Ge position passback button, can return to the information of oneself on individual calling or group calling intercommunication user terminal.
The receiver module of locating information, when a certain handheld terminal is during in one of individual calling object user or group calling user, the other side's handheld terminal sends after locating information, the machine can receive, and by its position display on screen.
Historical track is preserved and track passback module, and the machine motion track can be kept in the machine, can return to general headquarters' data bank if necessary.After receiving distant terminal locating information, dog-leg path can be preserved and draw, and certain stage track data can be called.
Should be appreciated that the above detailed description of technical scheme of the present invention being carried out by preferred embodiment is illustrative and not restrictive.Those of ordinary skill in the art modifies reading the technical scheme that can record each embodiment on the basis of specification of the present invention, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
