Description
Technical field
The present invention relates to a kind of field of wireless communication, more particularly to the wireless communication system design that kind modulus adaptively switches
Method.
Background technology
DMR（Digital Mobile Radio）Wireless communication standard is a kind of number that European Communication Standard association releases
Cluster standard.Due to its significant technical advantage, as soon as become the main trend of intercom development, design of the invention
It is to be based on DMR systems.
Professional field of wireless communication analog-to-digital conversion has become certainty at this stage, but analog machine possesses perfect network,
A period is needed when switching, how to be transitted smoothly to number is the problem of needing to pay attention in analog-digital conversion process.It is existing
DMR equipment needs manually select and be operated in analog channel or digital channel, that is to say, that an equipment can only operate in one
Kind pattern.Although and the signal of respective channel can be swept to by opening automatically scanning, need frequent switching channel, thus be brought
Expense it is also larger（Power consumption etc.）, access also not in time.The present invention proposes that a kind of adaptive method is waited in corresponding channel,
When intercom is under reception state, there is analog signal then to automatically turn on analog link and received, have digital signal with regard to automatic
It opens digital link to be received, is truly realized the seamless connection of modulus.It is then determined in transmit state by configuring parameter
It is simulation model or figure pattern.
Invention content
The technical problem to be solved in the present invention is to provide a kind of wireless communication system design side that modulus adaptively switches
Method, by same channel in receive state modulus automatically switch and emission state under according to parameter setting emit work side
Method solves previous respective channel and is once set to operating mode, the shortcomings that can not just carrying out schema modification in use.
The present invention specifically comprises the following steps：
Step 10, the intercom chosen while supporting figure pattern and simulation model；
Step 20, the setting for completing intercom configuration parameter；
Step 30, the setting that parameter is configured according to intercom, the modulus being automatically performed under reception state and emission state are cut
It changes；The switching needs of the reception state are first detected signal strength, when signal strength reaches certain threshold value, then pass through
The frame synchronizing signal of figure pattern carries out mode decision, finally enters corresponding link according to judging result；The emission state
Switching first starts emission function, and corresponding link is directly entered further according to the operating mode of configuration；
Step 40, display related interfaces simultaneously do corresponding prompt to number or simulation model.
Further, in the step 20, the configuration process of relevant parameter includes as follows：
201, the parameter setting of respective channel figure pattern and simulation model is completed；
202, the operating mode under present channel reception state is set by mode parameter；
203, the operating mode under present channel emission state is set by mode parameter.
Further, in the step 202, the operating mode under reception state includes figure pattern, simulation model and mould
Number automatic identification model, and the modulus automatic identification model is equipped with priority.
Further, in the step 203, the operating mode under emission state includes figure pattern and simulation model.
The invention has the advantages that：Adaptively switched by software completely in handoff procedure, be not necessarily to human intervention,
Carry out multi channel frequent switching without opening scanning so that turn-on time faster, software overhead smaller；It is realized in same channel
Multi-mode switches, and improves channel capacity.

Specific implementation mode
It please refers to shown in Fig. 1 to Fig. 3, a kind of wireless communication system design method that modulus adaptively switches specifically includes
Following steps：
Step 10 chooses bimodulus intercom, i.e., supports figure pattern and traditional simulation model simultaneously；
Step 20, the setting for completing intercom configuration parameter.The setting procedure of the configuration parameter is as follows：
Step 201, by writing frequency software or other modes（Such as menu）Complete respective channel figure pattern and simulation
The parameter setting of pattern, specific setting method is set with currently used digital parameters and analog parameter setting is consistent.
Step 202 sets the operating mode under present channel reception state by mode parameter, such as：WorkmodeRx=
It is figure pattern when 0；It is simulation model when WorkmodeRx=1；It is modulus automatic identification model, mould when WorkmodeRx=2
Number automatic identification model is equipped with priority again, and the priority is either figure pattern can also be preferentially that simulation model is excellent
First.Wherein WorkmodeRx indicates reception state.
Step 203 sets the operating mode under present channel emission state by mode parameter, such as：WorkmodeRx=
It is figure pattern when 0, is simulation model when WorkmodeTx=1.Wherein WorkmodeTx indicates emission state.
Step 30, radio software are according to the setting of configuration parameter, the mould being automatically performed under reception state and emission state
Number switching.Specific implementation flow is as follows：
Workflow under reception state：As shown in Fig. 2, first to the intensity of aerial signal（RSSI）It is detected, when
When RSSI reaches certain threshold value, with regard to carrying out mode decision；The mode decision is sentenced by the frame synchronizing signal of figure pattern
It is disconnected, it is just directly entered digital function receives link when it is digital synchronization signal to detect, is otherwise put into analog functuion reception
Link.
Workflow under emission state：As shown in figure 3, first starting emission function, further according to the operating mode of configuration（Number
Word pattern or simulation model）It is directly entered digital function transmitting link or analog functuion transmitting link.
Step 40, display related interfaces simultaneously do corresponding prompt to number or simulation model.
