Step 3 after completion to be received, carries out data check, if verification passes through, enters step four, if verification is obstructed
It crosses, then repeatedly step 2, and carries out abnormality alarming after secondary data verification does not pass through yet；
Firmware is write new starting address by step 4；
The electronics price tag includes at least two starting addresses, and first starting address stores current firmware, and second is opened
Dynamic address stores new firmware.
Further, it is above-mentioned be suitable for electronic tag exempt from disassemble firmware upgrade method, wherein it is described in step 1
The OTA firmware of upgrading is carried out CRC16 verification by base station, by obtaining the banner word of 8 bytes, the firmware of 2 bytes after splicing subpackage
Length, the CRC16 check value of 2 bytes, remainder data is firmware data.
Further, it is above-mentioned be suitable for electronic tag exempt from disassemble firmware upgrade method, wherein in step 1, hair
Sending mode is 4G/5G communication modes or WIFI mode or bluetooth approach.
Further, it is above-mentioned be suitable for electronic tag exempt from disassemble firmware upgrade method, wherein it is every in the subpackage
The length of a packet is 64 bytes, and packet first four byte is the quantity and packet index of packet respectively, and 60 bytes are firmware partition to packet below
It forms.
Further, it is above-mentioned be suitable for electronic tag exempt from disassemble firmware upgrade method, wherein the step 3
In, if secondary data verification does not pass through yet, the abnormal warning information of electronics price tag display upgrading, and continue to use normal before upgrading
Firmware.
Still further, above-mentioned exempts from dismantling firmware upgrade method suitable for electronic tag, wherein the step 4
In, carry out a data check again after the completion of write-in, to be verified by rear, the confirmation write-in of electronics price tag is completed, and switching is opened
Simultaneously restart dynamic address.
According to the above aspect of the present invention, the present invention has at least the following advantages:
1, it does not need to unload from shelf or showcase, does not have to disassembly battery and shell, lossless upgrade may be implemented.
2, special programming tool is not needed, the needs that noninductive upgrading updates firmware are met.
3, technical staff's field conduct is not needed, producer can remotely update firmware updating, improve the convenience degree of upgrading.
4, the electronics price tag of defective firmware can be upgraded by new function, avoided technical staff with remote repairing
To field operation, the safety of product is improved, saves product maintenance cost, improves competitive power of product.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, with presently preferred embodiments of the present invention, detailed description is as follows below.
Specific embodiment
With reference to embodiment, the embodiment of the present invention is furthur described in detail.Following embodiment is used for
Illustrate the present invention, but is not intended to limit the scope of the invention.
Suitable for electronic tag exempt from disassemble firmware upgrade method, unusual place be the following steps are included:
Firstly, subpackage is sent to electronic tag after being spliced the OTA firmware of upgrading by base station.Specifically, base
It stands and the OTA firmware of upgrading is subjected to CRC16 verification, by obtaining the banner word of 8 bytes after splicing subpackage, the firmware of 2 bytes is long
Degree, the CRC16 check value of 2 bytes, remainder data is firmware data.
In particular it relates to OTA firmware structure it is as shown in the table:
| Banner word (8 byte) | Firmware length (2 byte) | Firmware data | CRC16 (2 byte) |
Subpackage structure is as shown in the table:
| The quantity (2 byte) of packet | The index (2 byte) of packet | The content (60 byte) of packet |
Meanwhile being laid out for different local communications, in order to realize that more quick, lossless data are sent, the present invention is adopted
Sending method is 4G/5G communication modes or WIFI mode.Also, for the distribution electronic tag of certain centralization
Upgrading needs, and can also use bluetooth approach.
Quick indexing is realized for the ease of electronic tag, provides convenience for upgrading detection, each packet in subpackage of the present invention
Length is 64 bytes, and packet first four byte is the quantity and packet index of packet respectively, and 60 bytes are that firmware decouples to packet below.
Later, the data packet received is stored in specified region by indexed sequential and saved by electronics price tag.
Then, after completion to be received, data check is carried out, if verification passes through, enters subsequent processing.
If verification does not pass through, repeat to carry out secondary data verification after receiving one time, and do not lead to yet in secondary data verification
Later abnormality alarming is carried out.Specifically, if secondary data verification does not pass through yet, the abnormal alarm of electronics price tag display upgrading
Information, and continue to use the normal firmware before upgrading.
By taking the address AB as an example, address structure of the present invention is as shown in the table:
| Start address (A/B) | The address firmware A | The address firmware B | Other data |
In this way, OTA upgrading can all switch starting address every time, being currently up address is A, and new firmware is with will having B
Location, when new firmware verifies OK, starting address will be switched to the address B.
All may be used finally, firmware is write new starting address.In order to improve the reliability of upgrading, after the completion of write-in again
A data check is carried out, to be verified by rear, the confirmation write-in of electronics price tag is completed, and switching starting address is simultaneously restarted, and is completed most
Whole upgrading.
The electronics price tag that the present invention uses includes at least two starting addresses, and first starting address stores current firmware,
Second starting address stores new firmware.In this way, not influencing original firmware operation during upgrading, may be implemented after upgrading successfully suitable
Benefit switching.Original firmware can be maintained to run after upgrading failure and be checked.
It can be seen that after applying the present invention by above-mentioned character express, gather around and have the following advantages:
1, it does not need to unload from shelf or showcase, does not have to disassembly battery and shell, lossless upgrade may be implemented.
2, special programming tool is not needed, the needs that noninductive upgrading updates firmware are met.
3, technical staff's field conduct is not needed, producer can remotely update firmware updating, improve the convenience degree of upgrading.
4, the electronics price tag of defective firmware can be upgraded by new function, avoided technical staff with remote repairing
To field operation, the safety of product is improved, saves product maintenance cost, improves competitive power of product.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
