Description
Technical field
The present invention relates to air-conditioning manufacturing technology field, in particular to a kind of air-conditioning firmware upgrade method, a kind of air-conditioning
Device for upgrading firmware, a kind of air-conditioning, a kind of computer equipment, a kind of computer-readable recording medium.
Background technology
Air-conditioning products are in use, need to carry out firmware upgrade to control chip for some reason, traditional product is limited
In firmware size, upgrade method is single, only carries out simple firmware upgrade management mostly, such as escalation process power-off, transmission upgrading
During data, interference is received, or escalation process needs pause etc., causes this time upgrading failure, then needs to upgrade again.With chip
Function is stronger and stronger, and firmware size is increasing, and upgrading mode is more and more diversified.If repeatedly upgraded again, gesture
The problems such as update time must being caused to increase, upgrading control centre's burden.
Therefore, how to propose a kind of firmware upgrade management method for supporting breakpoint transmission, become skill urgently to be resolved hurrily at present
Art problem.
The content of the invention
It is contemplated that at least solve one of technical problem present in the prior art or correlation technique.
For this reason, it is an aspect of the invention to propose a kind of air-conditioning firmware upgrade method.
Another aspect of the present invention is to propose a kind of air-conditioning device for upgrading firmware.
Another aspect of the invention is to propose a kind of air-conditioning.
Another aspect of the present invention is to propose a kind of computer equipment.
Another aspect of the present invention is to propose a kind of computer-readable recording medium.
In view of this, the present invention proposes a kind of air-conditioning firmware upgrade method, including：Detect firmware upgrade file cache area
Fileinfo, determine whether unfinished firmware upgrade flow；If so, the check information of each file data bag is detected, when
During check information mistake, the bag sequence number of current file data packet is determined；Communicate, sent comprising bag sequence number with control centre
Repeat requests, and receive the firmware upgrade file retransmission bag of control centre's transmission.
Air-conditioning firmware upgrade method according to the present invention, after firmware upgrade procedure is started shooting or re-powered, passes through detection
The information of upgrade file in firmware upgrade file cache area, to determine whether having unfinished firmware upgrade flow, if having unfinished
Firmware upgrade flow, then detect the check information of each file data bag successively, when check information mistake, illustrate current file
Data packet is the point of interruption of last upgrading, it is determined that the bag sequence number of current file data packet, and send and rise to control centre
Level repeat requests, request needs the bag sequence number retransmitted, after control centre receives request, starts the firmware upgrade that transmission needs to retransmit
File bag.By technical scheme, there is situations such as powered-off fault, error in data, pause upgrading in firmware upgrade process
When, when powering on again or asking upgrading again, an escalation process before continuing, and once the upgrading point of interruption starts in the past
Transmission does not transmit the firmware upgrade file of completion, so as to increase the stability of firmware upgrade, shortens the extensive of big firmware upgrade exception
The multiple time, while mitigate the transmission burden of control centre.
In the above-mentioned technical solutions, it is preferable that determine the bag sequence number of current file data packet, be specially：According to ought be above

It is made of two parts：Boot program and APP application programs, the program's memory space of control chip, be also classified into boot memory blocks with
APP application programs memory block.Firmware upgrade is to carry out firmware upgrade for APP application programs, and boot program is responsible for delaying in firmware
File renewal is deposited to APP application areas.APP application programs include the different upgrading modes that manage, and firmware file receives and caching,
And the preservation and recovery of upgrade status.
The workflow of boot program, as shown in Figure 9：
Step 902, judge whether firmware file buffer area has firmware to need to update；When judging result is to be, step is performed
Rapid 904；When judging result is no, step 908 is performed；
Step 904, judge whether firmware file caching area file is legal；
Step 906, it is if legal, carry out firmware upgrade；If illegal, step 908 is performed；
Step 908, APP application programs are performed.
Firmware upgrade control flow, as shown in Figure 10：
Step 12, it is connected with firmware upgrade control centre；
Step 14, firmware file buffer area is scanned, detects whether to preserve unfinished firmware upgrade flow；
Step 16, if there is unfinished firmware upgrade flow, repeat requests are sent；
Step 18, if the firmware upgrade flow not completed, whether inquiry has upgrade request；
Step 20, if without upgrade request, application program is performed；
Step 22, if there is upgrade request, firmware file information is received；
Step 24, the first bag firmware file data are received；
Step 26, N bag firmware file data are received；
Step 28, receive firmware and be sent message；
Step 30, firmware file buffer area file validation is detected；If illegal, return to step 14；
Step 32, renewal mark that is if legal, setting firmware upgrade to need；
Step 34, restart.
In this embodiment, control centre is not limited to serial ports upgrading of control software or remote server upgrading control journey
Sequence, firmware file information are stored in the program's memory space of control chip, and firmware file data packet is stored in firmware file caching
Area.The firmware upgrade management method provided by the invention for supporting breakpoint transmission, can upgrade exception with monitor firmware, while according to different
Reason condition carries out upgrade file breakpoint re-transmission, to reach increase upgrading stability, shortens the big firmware upgrade abnormal restoring time.
As shown in figure 11, the schematic diagram of computer equipment according to an embodiment of the invention.Wherein the computer is set
Standby 1100, including memory 1102, processor 1104 and be stored on memory 1102 and can be run on processor 1104
Computer program, processor 1104 are used to perform such as the step of any one of above-described embodiment method.
Computer equipment 1100 according to the present invention, its processor 1104 included are used to perform such as any of the above-described implementation
In example the step of air-conditioning firmware upgrade method, thus the computer equipment 1100 can realize the complete of the air-conditioning firmware upgrade method
Portion's beneficial effect, details are not described herein.
The fifth aspect of the present invention embodiment, it is proposed that a kind of computer-readable recording medium, is stored thereon with computer
Program, realizes when computer program is executed by processor such as the step of any one of above-mentioned any embodiment method.
Computer-readable recording medium according to the present invention, the computer program stored thereon are realized when being executed by processor
As in above-mentioned any embodiment the step of air-conditioning firmware upgrade method, thus the computer-readable recording medium can realize this
Whole beneficial effects of air-conditioning firmware upgrade method, details are not described herein.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
