Specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this
Bright each embodiment is explained in detail.However, it will be understood by those skilled in the art that
In each embodiment of the present invention, in order that reader more fully understand the application and propose many technology thin
Section.But, even if there is no these ins and outs and the many variations based on following embodiment and modification,
The each claim of the application technical scheme required for protection can also be realized.
The first embodiment of the present invention is related to a kind of dual-mode wireless communication method.In present embodiment
" bimodulus " with the first short-range communication pattern as BLE and the second short-range communication pattern for ZigBee is
Example illustrates.Its flow process is as shown in figure 1, specific as follows：
Step 101, allocates call duration time point and the dormancy time of each short-range communication pattern in advance.
Specifically, this step can be subdivided into following steps：
Step A1, if the signal receiving is networking broadcast singal, according to the feature of each communication pattern
The communication pattern of the signal received by format identification.
Specifically, it was found by the inventors of the present invention that two kinds of communication standards data bandwidth, modulation system,
And obvious difference is had on the regulation of data preamble, BLE and Zigbee in present embodiment exists
Also all have any different on these forms.These have the regulation being clearly distinguished from can as the characteristic format of signal,
If characteristic format can be made a distinction, the communication pattern of data also just can be distinguished.
In particular, this step is to be identified according to the characteristic format of each short-range communication pattern to be received
The communication pattern of the data arriving.In particular, characteristic format can comprise one below or its any group
Close：Data bandwidth, modulation system data lead code.
It should be noted that " the leading to of the signal received according to the identification of the characteristic format of each communication pattern
The step of letter pattern " can be refined as following three step：
Step B1, extracts the data of predeterminated position in received signal；Wherein, this predeterminated position is by being received
The position of the characteristic format of its short-range communication pattern is characterized in signal.
Step B2, compares the extracted data and each short-range communication pattern normal data in correspondence position.
Step B3, judges the communication pattern of received signal according to comparative result.
After having executed above-mentioned steps, continue executing with following steps：
Step A2, according to the communication pattern being identified, distributes corresponding call duration time point and dormancy time.
Specifically, the call duration time point of allocated BLE and the call duration time point of ZigBee differ.
It should be noted that this step 101 is the execution in dual-mode wireless communication networking, in dual-mode wireless
During constructing communication network, the equipment initiating networking passes through broadcast mode, first all of logical according to BLE Mode scans
Letter frequency channels, find out attachable BLE destination object, all of according still further to ZigBee Mode scans
Communication frequency channels, find out attachable ZigBee destination object.Requiring and protocol security through user
After verifying attachable target, set up communication connection respectively with BLE and Zigbee of surrounding.
It should be noted that, in present embodiment, when this step is the communication of distribution BLE and ZigBee
Between point and dormancy time, meanwhile, the allocated call duration time point of BLE and the call duration time of ZigBee
Point differs.The call duration time point of both of which and dormancy time are staggered, that is, makes two kinds of agreements
Time division way is all adopted to communicate, the interval section (i.e. dormancy time) run in a certain communications protocol, can
To run another communication so that the data of different short-range communication pattern will not be same in the same time
Conflict in communication channel, and two kinds of communication patterns are permissible in processing data or transceiving data on hardware
Share some components and parts, cost-effective.
It is noted that this step is the step that communication first carries out in advance, that is, the initialization of networking
Step in journey, the step being had to carry out when not communicating every time.
Step 102, using RF transceiver receiving data.
Specifically, this step is in the communication of the call duration time point of allocated BLE and ZigBee
Between point, using RF transceiver receiving data.

Its structure can be Direct Conversion, Low Medium Frequency, double conversion, two point form modulation or direct lack sampling.
It should be noted that due in present embodiment RF transceiver need send BLE and ZigBee
The data of both of which, so needing to meet the design requirement of both of which, such as, sensitivity, anti-dry
Disturb, transmission signal quality, phase noise, automatic growth control etc. index must all is fulfilled for two agreements
In most stringent one.
For example, BLE standard requires, therefore radio frequency receipts higher than Zigbee requires to interference free performance
Send out the index of the impact interference free performance such as the middle linearity of device, channel model filtering performance, phase noise
Require to be designed according to BLE standard, certainly meet the index request of Zigbee meanwhile；And Zigbee
In the application such as Industry Control, networking, requirement to the receiving sensitivity requirement than short haul connection BLE is more
Height, therefore for receiver design, the index such as noise coefficient, signal link gain must be according to Zigbee
Requirement be designed.Other correct with regard to control and the circuit for rectifying of RF transceiver, process deviation,
The circuit such as automatic growth control, frequency deviation rectification, due to not having direct correlation with agreed standard requirement, therefore may be used
With two standard common.
Additionally, it is noted that in actual applications it is also possible to not adopt shared radio frequency transceiver
Design, and use two single RF transceivers, design is more simple.
Step 103, confirms the communication pattern of received data.
Specifically, this step is to confirm its communication pattern according to the reception time of received signal.
Wherein, communication pattern comprises BLE and ZigBee.Because the signal for different communication modes has not
Same call duration time point, so this step can accurately judge its communication pattern according to the reception time of signal.
Step 104, carries out the demodulation process of associative mode to received signal.
Specifically, because the demodulation process that the signal of different mode is carried out after the receipt is entirely different
, so after confirming to receive the concrete communication pattern of signal in abovementioned steps, could be according to corresponding
Pattern be demodulated process.
Step 105, the articulamentum that received signal is carried out with associative mode is processed.
Specifically, be attached layer process in this step is the data processor of articulamentum, is a kind of
Use hard-wired mode.(in radio communication, the standard of each layer is divided into physical layer, articulamentum, application
Layer etc.) in actual applications it is also possible to be realized with the mode that MCU executes software instruction.
It is noted that the protocol stack in present embodiment is that the protocol stacks such as BLE and ZigBee are entered
Row merges the protocol stack after optimizing.
To sum up, present embodiment in terms of existing technologies, mainly according to different short-range communication patterns
The different principle of characteristic format, during networking initialization, the data receiving is identified, and to knowledge
Different pieces of information after not is respectively allocated different call duration time points, in receiving data, can quick DIGEN
According to the timing separation received signal receiving, the signal after distinguishing is carried out the modulation /demodulation of associative mode
Process and the articulamentum of associative mode is processed, thus realizing the self-adaptive processing to different communication modes data,
Due to receiving and dispatching the data of corresponding modes according to pre-assigned call duration time point so that the data of different mode
Will not conflict in same communication channel of same time.It can be seen that, the dual-mode wireless communication in present embodiment
Method allows to support two kinds of short-range communication patterns, expanded application market during radio communication simultaneously.

Step 203, the signal that need are sent carries out the modulation treatment of associative mode.
Step 204, the signal being sent using the need that RF transceiver sends associative mode.
Specifically, step 202 to step 204 is the letter of step 102, step 104 and step 105
Number transmission process.The communication pattern of the data sending as needed, carries out different pieces of information to it and corresponds to
The pretreatment of pattern is so that the dual-mode wireless communication method in present embodiment can be supported to send two simultaneously
Plant the data of short-range communication pattern.

Can be realized to two kinds of lattice of BLE and ZigBee using components and parts using bimodulus modem
The data of formula is modulated demodulation process, its data handling procedure as shown in figure 3, it is noted that
The generation CRC circuit of two of which pattern, white noise circuit, remove white noise circuit and follow
Ring redundancy encoding checking circuit all can share, because in present embodiment, two kinds of communication protocols adopt the time-division
Mode is communicated, so sharing of partial circuit can't cause to interact, on the contrary can be further
Save the use of components and parts.
