Description
Technical field
It is specifically a kind of method for upgrading software of small memory device the present invention relates to Optical Distribution Network apparatus field.
Background technology
As shown in figure 1, optical distribution network device upgrade system includes network management system（Including ftp server）, intelligent management
Terminal, optical distribution network equipment（MMU, DMU, DCU etc.）, the main upgrade path of optical distribution network device object has two kinds：One
It is directly to send upgrade command to optical distribution network equipment from network management system to plant, and the upgrading that the parsing of optical distribution network equipment is received refers to
Order, therefrom obtains the filename of user name, password and the equipment of ftp server, and the file for downloading equipment by File Transfer Protocol is carried out
Updating operation.Another is that Intelligent management terminal sends upgrade command to optical distribution network equipment, and Intelligent management terminal directly will
File sends optical distribution network equipment to, and optical distribution network equipment carries out updating operation again.
The upgrade method of above-mentioned optical distribution network equipment is all by all upgrading subfiles（Close to 2M）All it is transferred to
In internal memory, then upgrade file write into flash, this internal memory for being accomplished by the use of optical distribution network equipment is greater than whole upgradings
Subfile.And the memory headroom that optical distribution network device upgrade takes is larger, power consumption is higher during upgrading, it is impossible to meet user to production
The requirement of product low-power consumption；Memory chip price used also costly, increases cost；The address wire needed is on the high side, use
I/O interfaces are also increased, and the complexity of whole hardware circuit also increases.
The content of the invention
For defect present in prior art, it is an object of the invention to provide a kind of software upgrading of small memory device
Method, the memory headroom that optical distribution network device upgrade takes is small, reduction upgrading power consumption, saves memory chip cost, simplifies hard
Part circuit complexity.
To achieve the above objectives, the present invention provides a kind of method for upgrading software of small memory device, including network management system liter
The step of the step of level optical distribution network equipment and Intelligent management terminal upgrading optical distribution network equipment, network management system is directly to light
When distribution network equipment sends upgrade command, the memory headroom of optical distribution network equipment is directly write after receiving a upgrading subfile
Enter in flash, memory headroom then deletes this time upgrading subfile, next upgrading subfile is received again, until all liters
Level subfile all writes flash；When Intelligent management terminal is to optical distribution network equipment transmission upgrade command, optical distribution network is set
It is interior in write-in flash after standby memory headroom receives a upgrading subfile, and check (CRC) and upgrading subfile numbering are correct
Deposit space and then delete this time upgrading subfile, next upgrading subfile is received again, until all upgrading subfiles are whole
Write flash；Wherein, maximum the big of subfile of upgrading under not less than two kinds upgrade cases of the memory headroom of optical distribution network equipment
It is small.
On the basis of above-mentioned technical proposal, the network management system directly sends upgrade command to optical distribution network equipment
When, the ftp server that optical distribution network equipment connects network management system by its FTP customer side downloads upgrading subfile.
On the basis of above-mentioned technical proposal, the upgrade command that the optical distribution network equipment parsing network management system is sent,
Ftp server user name, password and upgrade file name are obtained, if obtaining failure, optical distribution network equipment is fed back to network management system
Obtain failure information.
On the basis of above-mentioned technical proposal, the network management system directly sends upgrade command to optical distribution network equipment,
When the memory headroom of optical distribution network equipment receives each upgrading subfile, judge whether the upgrading subfile is stored in internal memory empty
Between, if so, the upgrading subfile is write in flash；If it is not, network management system upgrading failure is informed in the way of trap, and clearly
Except the flash having been written into.
On the basis of above-mentioned technical proposal, when network management system directly sends upgrade command to optical distribution network equipment, institute
There is upgrading subfile all to write after flash, optical distribution network equipment informs that network management system is upgraded successfully in the way of trap.
On the basis of above-mentioned technical proposal, the Intelligent management terminal sends upgrade command to optical distribution network equipment
When, optical distribution network equipment obtains the optical distribution network device type of upgrading, upgrading subfile quantity, if obtaining failure, light
Distribution network equipment obtains failure information to Intelligent management terminal feedback.
On the basis of above-mentioned technical proposal, the Intelligent management terminal sends upgrade command to optical distribution network equipment,
The memory headroom of optical distribution network equipment receives each upgrading subfile, judges that the upgrading subfile is stored in memory headroom right,
If so, further verifying whether upgrading subfile CRC succeeds, if success, the upgrading subfile is write in flash, feedback
Successful information is received to Intelligent management terminal；If the upgrading subfile is not stored in memory headroom or verifies subfile CRC
Failure, then feed back error message to Intelligent management terminal, terminates upgrading.
On the basis of above-mentioned technical proposal, the Intelligent management terminal sends upgrade command to optical distribution network equipment
When, all upgrading subfiles are all after write-in flash, and optical distribution network equipment is given out a contract for a project to be escalated into Intelligent management terminal feedback
Work(.
On the basis of above-mentioned technical proposal, the network management system directly sends upgrade command to optical distribution network equipment
When, each upgrading subfile is 256 bytes；When Intelligent management terminal is to optical distribution network equipment transmission upgrade command, Mei Gesheng
Level subfile is 1300 bytes；The memory headroom of the optical distribution network equipment is not less than 1300 bytes.
The beneficial effects of the present invention are：
1st, the memory headroom of optical distribution network equipment only needs to store each upgrading subfile, therefore memory headroom reduces,
The upgrading of optical distribution network equipment can be completed using small internal memory, the memory chip of use reduces therewith, substantially reduces light and matches somebody with somebody
The cost of the line network equipment, there was only 2M internal memories such as 256K memory chip price, the cost of optical distribution network equipment
50% or so can be reduced.
2nd, with the reduction of memory headroom, the power consumption of optical distribution network equipment is also decreased, and saves the energy.
3rd, memory headroom reduces, and the address wire that optical distribution network equipment needs just relative reduction, the I/O interfaces of response also may be used
To reduce, reduce the complexity of whole hardware circuit, for example using 32K memory headroom, it is necessary to address wire be 15, relatively
For 21 address wires that 2M memory headrooms need, 6 address wires are reduced.
