Store up control unit, control parameter unit and several Serial Advanced Technology Attachment interfaces.
On the basis of above-described embodiment, the present invention provides a kind of signal analysis method of large capacity quick storage playback,
For the storage of not losing high-speed sample data continuously to hard disk, and realize the recovering and analysis of data, wherein, including following
Step (as shown in Figure 2)：
Step 1：Wideband IF signal enters after data acquisition module carries out analog-to-digital conversion and enters data processing module；
Step 2：Data processing module will enter to be stored back into after signal digital mixing and filtering extraction processing puts control module；
Step 3：Storage playback control module control data are directly output to host cpu module or by double
It is exported after caching First Input First Output to hard-disc storage control unit；
Step 4：Hard-disc storage control unit simultaneously assigns to the data of generation several according to the setting of control parameter unit
Serial Advanced Technology Attachment mouth is carried out at the same time data storage；
Step 5：The storage state of each Serial Advanced Technology Attachment mouth is saved in the state of hard-disc storage control unit
In word, read and analyzed by host cpu module；
Step 6：A stored record message file is established in the system disk of host cpu module mounting, is used
In the specific location in recording disk of size and data of records store data, and current software and hardware running parameter
It is added in as file header；
Step 7：Stored record message file in the system hard disk searches the sky of recording disk by host software
White region is stored since white space；
Step 8：The total amount of data write-in that the hard disk serial number of start recording, sector index are numbered and recorded is stored back into
The control parameter unit of control module is put, proceeds by signal analysis；
Step 9：When the signal parameter for finding to conform to a predetermined condition occurs, the control of host cpu module is stored back into
Put control module log-on data stored record；
Step 10：Data in two-way caching First Input First Output are passed through hard-disc storage control by storage playback control module
The control of unit processed, flowing water are decomposed in the recording disk of deposit mounting, each recording disk one sector of cycle assignment in order
Data volume i.e. 512 bytes, the read and write access order of sector is as shown in Figure 3 in multiple recording disks；
Step 11：When signal analysis device is operated in playback state, being chosen by host software from system disk will
The record file of playback reads file header in file, and the software and hardware running parameter in file header is reset to signal analysis
In device；
Step 12：Data are switched to hard disk playback access by storing playback control module, it is hard to read record in file
Location information on disk including hard disk serial number, initial sector index, total record data volume, and these location informations is write
The control parameter unit of storage playback control module, and storage playback control module is controlled to start to play back；
Step 13：Storage playback control module is read record data from recording disk and is put into playback by the parameter set
Buffering area, host cpu module start to read data by Peripheral Component Interconnect STD bus.
Host cpu module is completed the control of multiple SATA2 hard disks by hard-disc storage control unit, control ginseng
Several forms are：Total data volume, initial sector index, sector number, the inadequate sector of final data amount, pass through addition
Zero padding expires a sector, and filling data amount check is hard-disc storage control unit according to the data volume actually read and write and every number of sectors
The difference of 512 bytes in last sector addition or leaves out zero, and reading when carries out phase inverse processing, controls the logic parameter of hard disk
The conversion of (sector number) to hard disc physical parameter (magnetic head, sector, cylinder etc.) is completed by hard-disc storage control unit.
This method can also realize the sampled data record under triggering mode, and trigger condition is by host cpu module
It calculates, host cpu module is constantly in signal analysis state, when the signal parameter for finding to conform to a predetermined condition occurs
When, storage playback control module log-on data storage can be controlled immediately, avoided the loss of signal data, and can be improved record
The efficiency of storage.
In certain model signal analyzer, after on the one hand requiring signal analyzer that can record the sampling of 200MHz bandwidth in real time
Wideband data, the another aspect later stage can carry out recovering and analysis to the wideband data of record in itself by instrument.Signal is analyzed
The bandwidth of instrument maximum 200MHz quantifies that treated, and data rate is 500M bytes each second, using the recording disk interface of mounting
For SATA2, rotating speed is 7200 revolutions per seconds, storage speed reachable 300M bytes per second, therefore mounts 2 firmly using the present invention program
Disk peak value is up to 600M bytes per second, it is possible to realize that full rate records, this programme storage playback control module can be compiled by scene
The programming of journey gate array realizes that internal hard-disc storage control unit is directly by the data of the two-way First Input First Output of data buffer storage
Serial SATA2 interface data is converted to, the participation of central processing unit and host software etc. is not required, read-write rate can by scene
Programming gate array column clock directly determines, thus can ensure efficient read or write speed.After the program, signal analyzer can be with
Side records, and side analysis can also trigger efficient storage original signal data in real time.
User setting begins to start when signal analyzer finds to have more than the signal of threshold level in 3.2GHz frequencies
The initial data in entire intermediate-frequency bandwidth is recorded, and requires continuous record 1G bytes.Host software is looked into first from system disk
All record files are looked for, see connect recording disk has had been used up which sector of which hard disk, if last time is
1280 sectors of second hard disk are used, then the position disk 2 of current start recording, initial sector 1281, capacity 1G bytes, instrument
Device software first completes the foundation of record file in system disk, and running parameter such as frequency 3.2GHz, the intermediate frequency of current instrument
In the write-ins such as bandwidth 200MHz, datum -10dBm, channel attenuation amount 10dB record file, then reel number 2, initial sector is compiled
Numbers 1281, parameter deposit system disk of the capacity 1G bytes 3 in relation to record position, and this 3 parameter read-ins storage playback
Control module control parameter area proceeds by signal analysis, when analysis finds to have more than the letter of threshold level in 3.2GHz frequencies
Number when, immediately start stored record control, playback controls module then since the two-way First Input First Output of data buffer storage receive number
According to by 512 bytes being an one group i.e. sector data, the interleaved (as shown in Figure 4) that carries out is into two hard disks, Zhi Daoji
Until full i.e. 2097152 sectors of 1G bytes.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the technical staff in domain is made in the essential scope of the present invention should also belong to the present invention's
Protection domain.
