The embedded adaptive device 1 of interface, Fibre Optical Sensor and industry wireless network 4 of formula adaptive device 1 and industrial field bus network 3
Interface is using cycle double-buffering pool technical finesse.Recycle Network Programming Technology and multithreading that double-buffering pool technology uses Linux
The communication technology realizes that each group of double-buffering pool will respectively be realized using three threads：The storage of input interface data, storage data
Parsing and processing, treated data storage.Human-computer interaction interface is realized using QT4.8.5, mainly completes heterogeneous network
Between data flow line selection and pertinent system information show.
Since each communication interface has been all made of cycle double-buffering pool technology, following steps are only introduced wherein a certain communication and are connect
The cycle double-buffering pool technology of mouth.Include using the step of cycle double-buffering pool technical finesse：
31) two buffer pools are built.If the peak-peak communication data rate Abps of communication interface, minimum processing unit
Holding time piece is Bs, and the initial processing memory rate of data is Cbps.If A*B≤C*B, it is (C*B) b to open up two sizes
Buffer pool, otherwise open up two sizes be (A*B) b buffer pool.The cooperation principle of two buffer pools is：Buffer pool one is for connecing
By the high data rate from communication interface, this is based partially on DMA technology (Direct Memory Access) and buffer pool lock
Technology.After the data of buffer pool one are filled with, buffer pool two continues data storage, at data parsing at this time and processing module
The input data that reason buffer pool one has just stored, flows to option, by handling result with number in conjunction with the information flow of human-computer interaction interface
In the form storage to corresponding queue of group.After the data processing of buffer pool one is complete, the number in buffer pool two is then handled
According to, and the input data of communication interface transfers to store into buffer pool one.So recycle repeatedly.
32) according to communication interface data transmission rate, data parsing and processing module itself processing speed, accident pair
Data are parsed has handled the incremental time four that later discontinuous storage tape is come with the incremental time of processing module and input data
A impact factor intelligently adjusts buffer pool size.If communication interface data transmission rate function is f1(t), data parsing and processing
The processing speed function f of module itself2(t), accident parses data and the incremental time function of processing module is that input data has handled the processing unit occupancy that the incremental time that later discontinuous storage tape is come is minimum
Timeslice is Tunit.Then the time of new processing unit occupancy is about：Then a new round is for the size of the buffer pool of storage：
33) speed of adjustment data parsing and processing module.In step 32), it has been found that if data parsing and place
The processing speed of reason module is consistently less than the data entry rate of communication interface, and may result in can be ceaselessly for storing buffer pool
Be incremented by, final result is exactly that whole system memory is depleted.Data parsing and processing speed must be adjusted, two bufferings are made
Pond dynamically expands and reduces in controllable range, reaches and realizes protocol conversion and rate-matched using minimum overhead
Problem.The method of adjustment has：Data are parsed (to be reduced soft with the unexpected situation of the parallel plus-minus of processing module quantity, reduction system
Hardware interrupts), improve storage method and reduce unnecessary file read-write operations.
34) it is fitted according to the change curve of four impact factors in step 32).Scientific and reasonable matched curve is to make cycle
Double-buffering pool technology plays most powerful key.f1(t) method that experiment measures may be used in matched curve, is surveyed to experiment
Amount result is fitted.f2(t) related with designed data dissection process modular algorithm time complexity, for several parallel
Module the mode of weighted superposition can be used be fitted.Accident incremental time function depends on the integral frame of system, processing
Lars transformation can be used to its smoothing techniques due to being the time quantum of burst step in flow.Storage with design is calculated
Method time complexity is related.
By taking Fibre Optical Sensor demodulates terminal interface as an example.The peak data rate that Fibre Optical Sensor demodulates terminal is 4Mbps, is had
Two factors are depended on data volume：The number N for the demodulator disposed in fiber optic sensor network1(maximum deployment number is 128
It is a) and single sensor information content I1Byte, the curve are measured in real time by grid flow rate test module, and 1 arrives
Rate curve in 10 timeslices is as shown in Figure 4.Individual data parses the processing speed f with processing module2(t) it is one fixed
Value.It is a linear incremental.Shown in adjustment process table 1 of the double-buffering pool in 10 timeslices.
Adjustment process of 1 double-buffering pool of table in 10 timeslices
Experimental data shows that the cycle double-buffering pool technology reduces the packet loss of access interface, reduces heterogeneous network
Between communicate influence each other.
