In general, hand-held radio telephone (Handset Radio) abbreviation hand platform, is one kind relative to vehicle radio station, fixed radio station
The radio station of equal erection modes, use usually on the move, portability and flexibility are better than both rear.Hand-held radio telephone maximum hair
It penetrates power and is usually no more than 5W, usual specification has 0.5W, 2.5W and 5W etc..Hand platform is generally FM frequency range, seldom also there is shortwave frequency
Section, according to 2001《People's Republic of China's radio frequency divides regulation》, the legal frequency of radio amateur：
144.000-145.800 (the dedicated frequency range of amateur service), (amateur service is as secondary service and its by 430.000-435.000
Its business shares frequency range) and 438.000-440.000 (amateur service shares frequency range as secondary service and other business).Its
In, according to the standard wave length of 0.025MHz as defined in China, one shares 73 " dedicated " between 144.000-145.800MHz
Frequency point can be used；430.000-435.000, one share 282 " shared " available frequency points between 438.000-440.000MHz.
In addition, intercom is one kind of hand platform, it is a kind of bidirectional mobile communication instrument, is not needing the case where any mobile network supports
Under, so that it may it converses, is generated without telephone expenses, suitable for relatively fixed and frequently conversing occasion.
Hand platform module (not shown) provided in the present embodiment for realizing hand platform function, including ultrashort wave call and
The intercom functions such as forwarding, cover the legal frequency of above-mentioned radio amateur, but be not limited only to said frequencies, other
Army and police's frequency of use is also in coverage area.The respective pins of hand platform module (not shown) and microprocessor module (not shown) electricity
Connection, the control by microprocessor module (not shown).
Further, hand platform module (not shown) is electrically connected with external antenna 3, and external antenna 3 is installed on comprehensive emergency hand
1 first side 5 of communication terminal is held, the circuit that hand platform module (not shown) and external antenna 3 are constituted is used for will be from microprocessor mould
The data that block (not shown) receives are launched after coding, or for will pass to micro- place after the data received decoding
Manage device module (not shown).The process of encoding and decoding can microprocessor module (not shown) or hand platform module (not shown) into
Row only illustrates encoding and decoding the case where microprocessor module (not shown) is handled to this present embodiment without limiting.
Common coding is free time block code, Space-time trellis codes, hierarchical space-time code, concatenated code and iterative decoding, unitary blank time code and difference
Space Time Coding etc. under space -time code and frequency selective fading channels.
In the present embodiment, since hand platform module (not shown) may operate in multiple channels, comprehensive emergency handheld communication
Terminal 1 is also in comprehensive emergency 1 first side 5 of hand-held communication terminal equipped with channel rotary switch 2, for quickly selection and channel
The channel for the hand platform module (not shown) that rotary switch 2 is bound.Wherein, channel rotary switch 2 is multiple-pole switch, and every level-one is corresponding
One channel.Its working principle is that：Microprocessor module (not shown) controls hand platform according to the grade that channel rotary switch 2 is selected
The selection of module (not shown) progress channel.
The workflow row of opponent's platform module is carried out exemplary description by the present embodiment.Language is sent in hand platform module (not shown)
In the case where sound data, control selections corresponding channel of the hand platform module (not shown) by microprocessor module (not shown),
And the voice data by coding is received from microprocessor module (not shown), launched later by external antenna 3.In hand
In the case that platform module (not shown) receives voice data, hand platform module (not shown) receives voice data from external antenna 3
Coded data after, send microprocessor module (not shown) to and be decoded.
In the present embodiment, hand platform module (not shown) provides the function of ultrashort wave call and transfering the letter function, is suitable for
It converses frequent situation, such as user needs to link up by comprehensive hand-held communication terminal 1 of meeting an urgent need with companion in outdoor activities,
Determine locating geographical and personnel's situation.But due to the limitation of comprehensive emergency 1 power of hand-held communication terminal, (figure is not for hand platform module
Show) communication distance it is limited, the communication requirement of small range region can only be used in.So comprehensive emergency hand-held communication terminal 1 is also
Equipped with the function of public network intercommunication.
In general, the difference of the intercommunication function of public network intercommunication and hand platform module is that public network intercommunication is based on mobile cellular number
According to the intercommunication service of network, the limitation of communication distance not will receive.Public network intercommunication can rapidly carry out " one-to-one " or " one
To more " call, just as using intercom.

B, then the Push to talk over Cellular POC button 4 of comprehensive emergency hand-held communication terminal 1 starts to converse.This calling connection is almost wink
When complete.After one-to-one end of conversation, can discharge Push to talk over Cellular POC button 4 to make user B obtain floor,
It goes on repeatedly.In addition there are 3 kinds of different one-to-many group communication modes.According to the difference for mode of establishing, can divide
For chat group talk, instant group call and interim group call.Wherein, chat group talk can be divided into open chat group again
Group and limitation chat group.The former limits without member, everybody can be added；The latter must be that defined group member could add
Enter.Instant group call is the communication in group, and group member can participate in or exit at any time the cluster conversation.Interim group is logical
Words are the talk groups temporarily formed between user, and group is just without the member in group can invite it after conversation end
Other people be added, if but the people outside group without invite cannot voluntarily be added.
User is also an option that two kinds of answer modes：Auto-pickup mode and manual answer mode.Auto-pickup mode is just
It is that when first time being called (session establishment), terminal directly plays calling, and manual answer mode is needed when first time is called
User is wanted to be answered manually to establish connection.No matter which kind of mode is used, subsequent calling is all to play immediately.
Although public network intercommunication function solves the problems, such as long-distance talkback, due to needing using mobile cellular data network
Network, this allows for not being available the function in the unlapped area of mobile cellular data network.So comprehensive emergency handheld communication
Terminal 1 is further equipped with dipper system communication module (not shown) to be communicated using satellite.
In general, Chinese Beidou satellite navigation system (BeiDou Navigation Satellite System, BDS) is
The Global Satellite Navigation System that China voluntarily develops.Beidou satellite navigation system is by space segment, ground segment and user segment three parts
Composition, can round-the-clock in the world, round-the-clock be all types of user provide high-precision, it is highly reliable positioning, navigation, time service take
Business, and have short message communication capacity, tentatively have area navigation, positioning and time service ability, 10 meters of positioning accuracy, test the speed essence
Spend 0.2 meter per second, 10 nanosecond of time service precision.
In the present embodiment, dipper system communication module (not shown) is set in comprehensive emergency hand-held communication terminal 1, makes
The on the one hand available Beidou positioning information of emergency hand-held communication terminal 1 must be integrated, the short report of Beidou on the other hand can also be used
Literary system receives and dispatches short message.
