Detailed description of the invention
Fig. 1 is step schematic illustration of the invention.
Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in Figure 1, this NB mould group upgrade method, comprising the following steps: S1: be powered: NB-IoT mould group powers on simultaneously
Starting；S2: downloading decision: checking NB-IoT mould group and is confirmed whether that program is allowed to upgrade；S3: upgrade package downloading: NB-IoT mould
Group downloads from a server preset upgrade file；S4: downloading judgement: NB-IoT mould group judges whether upgrade file is downloaded into
Function；S5: it updates decision: increasing " in update " mark in NB-IoT mould group；S6:NB-IoT mould group updates；NB-IoT mould group adds
Carry the upgrade file of downloading；S7: it updates judgement: judging whether upgrade file loads into according to the program information of NB-IoT mould group
Function；S8: update terminates: NB-IoT mould group terminates more new state；S9: shutdown: NB-IoT mould group shuts down and disconnects power supply.
In this implementation, in firmware downloading process, decision judgement can be carried out according to the message that NB-IoT mould group pushes, if a)
" LWEVTIND:7 " is received, then is switched to and [updates decision-making state]；If b) receiving " DOWNLOAD FAIL ", switch
To [terminating state]；If c) receiving " UPDATE OVER ", it is switched to [delaying state]；If d) receiving time-out, cut
It changes to and [terminates state].
In this implementation, judgement is updated: if a) receiving " SUCCESS ", being switched to and [terminate state]；If b) received
To " FAILED ", then it is switched to and [terminates state]；If c) receiving " UPDATE OVER ", it is switched to [delaying state].
It further describes in detail, in order to prevent the repeated downloads of upgrade file, the time required to reducing upgrading, after step S1, also
Including step S11: it checks decision-making state: checking in NB-IoT mould group whether identify containing " in update " ,-if it does, then executing
Step S6；If not containing, S2 is thened follow the steps.
It further describes in detail, network environment is poor in order to prevent causes NB-IoT mould group long-time downloading upgrade file unsuccessful
It further include step S41 in step S4 to influence the service life of NB-IoT mould group: downloading timeliness judgement: NB-IoT mould group root
It whether is more than timeliness according to preset threshold decision upgrade file download time, if-it is more than to then follow the steps S9；If being no more than,
Then continue to download upgrade file, the threshold value is set as 20min in the present embodiment.
Further describe in detail, NB-IoT mould group moment, which shuts down, in order to prevent leads to system mistake, in step S9, NB-IoT mould group
Shutdown is provided with the delay time of 5S.
It further describes in detail, upgrade file long time loading is unsuccessful in order to prevent causes NB-IoT mould group to be in work for a long time
Make state, further include step S61 in step S6: update timeliness judgement: NB-IoT mould group upgrades text according to preset threshold decision
Whether the part load time is more than timeliness, if-it is more than to then follow the steps S7；If being no more than, continue loading upgrading file, this reality
It applies the threshold value in example and is set as 3min.
It further describes in detail, in step S2, if allowing to upgrade, sends upgrade signal, authorization mould group downloads upgrade file, liter
Grade signal is sent several times, then downloads upgrade file when mould group receives feedback signal；If not allowing to upgrade, transmission is forbidden upgrading
Signal, inhibited mode group download upgrade file, forbid upgrade signal to send several times, then exit more when mould group receives feedback signal
Newly.
In the present embodiment, if allowing to upgrade, sending " AT+QLWFoTAIND=2 ", authorization mould group starts to download firmware,
It sends " AT+QLWFoTAIND=2 " and uses retransmission mechanism, receive " oK " and then immediately begin to downloading upgrade file, otherwise retransmit 3 times
Start to download upgrade file again；If not allowing to upgrade, send " AT+QLWFoTAIND=3 ", under notice mould group does not allow
It carries, hair " AT+QLWFoTAIND=3 " uses retransmission mechanism, receives " oK " and then immediately exits from update, otherwise retransmits 3 times and exits again
It updates.
It further describes in detail, in step S5, when updating decision, sends and update id signal, the new firmware of authorization mould group enabling, hair
It send and updates id signal using retransmission mechanism, send successfully be increased by mark " in update " for the first time, it is more to update id signal point
Secondary transmission then starts loading upgrading file when mould group receives feedback signal, sends successfully be increased by mark " in update " for the first time,
Rather than it receives feedback signal and is further added by, in order to ensure to restart generation just during receiving feedback signal,
Cause to restart next time mould group is upgrading and master control also does other work in control mould group.
It in this implementation, when updating decision, sends " AT+QLWFoTAIND=4 ", authorization mould group enables new firmware, sends " AT
+ QLWFoTAIND=4 " uses retransmission mechanism, sends successfully be increased by mark " in update " for the first time, receive " oK " and then open immediately
Otherwise beginning loading upgrading file is retransmitted 3 times and starts loading upgrading file again.
