Step 11, the firmware upgrade packet for the intelligent electric meter that main website issues is received；
In this step, due to being communicated by local area network or GPRS between main website and concentrator, comparatively,
It is very fast to pass speed packet, therefore step cost for entirely upgrading process is substantially insignificant.With ammeter firmware liter
Grade packet 200k, every packet size are 1k, the time 2s of one packet of transmission, the time spent in total: (200/1) * 2s=400s, i.e., 7 points
Clock or so main website can pass to firmware upgrade packet on concentrator.
Step 12, in all ammeters for firmware upgrade packet being sent to downlink by way of broadcast.
In this step, except due to concentrator processing upgrading effect, there are also normal tasks, such as meter reading task dispatching
Deng therefore, concentrator of the present invention needs to suspend currently processed task after receiving the firmware upgrade packet of ammeter, by ammeter
Firmware upgrade task adjust to highest priority, in this way it is possible to prevente effectively from other tasks influence firmware upgrade, cause entire
The process of firmware upgrade lengthens, and influences the normal users situation of user.
Due to including multiple data subpackages in firmware upgrade packet, firmware upgrade packet is being sent out by way of broadcast
When sending into all ammeters of downlink, sequentially all data subpackages are broadcasted respectively to all ammeters according to the Bale No. of data subpackage
In.Specifically, include the following steps:
Step 121, the first of broadcast data subpackage is wrapped to all ammeters.
Here, the first packet carries the upgraded version number of firmware upgrade packet, is determined whether to ammeter according to upgraded version number
Carry out this upgrading.There may be different manufacturers or the electricity of same producer's different model in all ammeters hung under concentrator
Table, by the way that upgraded version number is arranged in the first data subpackage, can effectively ensure to upgrade is correct, avoids influencing other non-need
Upgrade the normal use of ammeter.
Wherein, in this step, it needs according to the first of preset number of broadcast times repeated broadcast data subpackage the packet.Here it sets
It is set to broadcast 3 times.Due to carrying upgraded version number in the first packet, and the version number is the key that determine subsequent upgrade.Therefore, exist
In the embodiment, in order to ensure that all ammeters can receive the first packet substantially, need to send repeatedly.Ammeter is receiving first point
Verify after packet to upgraded version number: if version number belongs to the ammeter of same model, ammeter is handled subsequent,
Otherwise the data subpackage of subsequent broadcast is not handled.
Step 122, sequentially data subpackage is broadcasted respectively from two packets to last packet into all ammeters according to Bale No..Electricity
After table receives data subpackage, if the data subpackage of subsequent transmission can be accepted after upper step processes the first data subpackage, into
Row data subpackage verifies (such as format check etc.), and data packet is put into corresponding memory space according to Bale No..
Wherein, when the data subpackage continued after transmission, it is preferred that divided data subpackage according to preset transmission time interval
It between that is, continuous two packet Guang Bo not need that effective time interval is arranged into all ammeters.In this embodiment, the time of setting
Between be divided into 5s, data subpackage can be effectively ensured in this way to be received, and avoid because while sending data subpackage leading to packet loss
The phenomenon that.
In order to further ensure the success rate of ammeter received data packet, in one embodiment of the invention, need to be repeated once step
Rapid 122 broadcast transmission operation.Ammeter determines received mistake after receiving the upgrade package issued, according to Bale No., then will
The data subpackage is abandoned, and otherwise needs to store corresponding data subpackage to corresponding storage location.
It, through the invention can be with based on above-mentioned it is found that by ammeter of the concentrator to lower extension do batch upgrade processing in this way
Human cost and time cost are effectively saved, the efficiency of firmware upgrade is improved.
Embodiment 2
Based on the above embodiments, under normal circumstances, after broadcast, most data subpackages transmission success, but
It is to equally exist the case where ammeter does not receive data subpackage.Therefore, in this embodiment, do not connect for a small number of data subpackages
The case where receipts, is defined.
Specifically, intelligent electric meter firmware upgrade method provided by the embodiment of the present invention, it is wide passing through firmware upgrade packet
After the form broadcast is sent in all ammeters of downlink, further includes:
Step 13, poll reads the packet receiving situation of every table, determines the packet receiving success rate of each data subpackage.
In this step, main website issues poll instruction to concentrator, and poll instruction is sent in each ammeter by concentrator,
And read the packet receiving situation of each table.Here packet receiving situation includes failure, success and corresponding data subpackage Bale No..This
Sample can determine which specific data subpackage receives successfully or reception failure.Wherein, after poll, concentrator periodically to
Main website is reported when forward pass bag-like state (packet receiving situation), allows main website to know current upgrading progress, wherein the period is settable, for
The ammeter that packet is completed is passed, repetition is not done and reports, but is to provide and passes packet progress queries interfaces, inquire main website can also with fixed cycle
Pass packet progress.
Step 14, it is determined by the way of broadcast/group broadcast/unicast according to packet receiving success rate by the data subpackage of transmitting-receiving failure
It is re-transmitted in corresponding ammeter.
In this step, first threshold and second threshold are preset.According to first threshold and second threshold, to judge to receive
Wrap the sending method of the data subpackage of failure.Here, the packet receiving success rate of each data subpackage=(N packet packet receiving is successfully electric
Table number)/(total upgrading ammeter number).
Specifically, it is determined by the way of broadcast/group broadcast/unicast according to packet receiving success rate by the data subpackage of transmitting-receiving failure
It is re-transmitted in corresponding ammeter, comprising:
When the packet receiving success rate of some data subpackage is less than the first preset threshold (such as 80%), then data subpackage is led to
The mode for crossing broadcast is sent in all ammeters；Alternatively,
When some data subpackage packet receiving success rate be greater than the first preset threshold and less than the second preset threshold (such as
90%) when, then data subpackage is sent to by way of multicast in the ammeter of data subpackage packet receiving failure；Alternatively,
When the packet receiving success rate of some data subpackage is greater than the second preset threshold and when less than 100%, then by data subpackage
It is sent to by way of unicast in the ammeter of data subpackage packet receiving failure.
Step 15, step 13 and step 14 are repeated, determines the sending method of follow-up data subpackage, until all ammeters are all received
It is bundled into function, i.e. packet receiving success rate is 100%.
Based on it is above-mentioned it is found that complete embodiment 1 in broadcast after, in order to guarantee that data subpackage is all received by ammeter, after
It is continuous that subsequent packet receiving failure sending method is determined according to the packet receiving state of data subpackage: when the packet receiving of certain data packets failure is high,
Data subpackage can be broadcasted again；And when packet receiving failure is relatively low, the mode that multicast can be used is sent, and is received
When packet failure is very low, unicast can be used and sent.Therefore, in this embodiment, mutually tied by broadcast, multicast and unicast
The sending method of conjunction, it can be ensured that firmware upgrade is completed with the smallest time overhead, is improved the efficiency of upgrading, is avoided to user
Normal electricity consumption cause to seriously affect.
