Abstract
Internet of things field of the present invention discloses a kind of upgrade method for internet of things equipment MCU, solves the problem of that little company lacks qualified technical personnel or without server MCU scaling difficulty.The original firmware of MCU is placed in NB IOT chip by the present invention first；Then when NB IOT upgrade when, NB IOT chip according to the original firmware of itself and the original firmware of MCU obtain respectively itself firmware updating and MCU firmware updating；Last MCU chip reads the firmware updating of MCU from NB IOT chip by instruction, and then completes the upgrading of MCU.Present invention MCU suitable for internet of things equipment upgrades.
Description
Technical field
The present invention relates to internet of things field, in particular to are used for the upgrade method of internet of things equipment MCU.
Background technique
The aerial downloading software upgrading of FOTA (Firmware Over-The-Air) mobile terminal, refers to and is upgraded by cloud
Technology, for the equipment with networking function: such as mobile phone, tablet computer, portable media player, mobile internet device
Firmware update services are provided, user obtains intelligent terminal system upgrade package using network with on-demand, easy extension way, and passes through
FOTA carries out cloud upgrading, completes system reparation and optimization.
The essence of FOTA is firmware upgrade, including driving, system, function, using etc. upgrading and hardware do not close directly
System.Applicable terminal range is very wide, upgrade service can be provided for terminals all in the market substantially, no matter for telecom operation
Quotient or terminal device manufacturer can be handled by cluster application, grid and Distributed Services end within the same time
The terminal upgrade demand of a large number of users.The relationship of FOTA and OS is closer, different os releases, and it is suitable to need to develop different FOTA
With version, while the system upgrade packet downloaded by FOTA module, also close matching is carried out with OS, not only to carry out hardware
The debugging of driving will also carry out the compatibility test of version, but such upgrade package is generally provided by manufacturer terminal, and FOTA is more
It is to guarantee to download upgrade package, and install to terminal, in the intelligent epoch, the standard for becoming intelligent terminal is matched in the upgrading of FOTA cloud
It sets.
NB IOT based on world's Internet of Things Strategic Demand, low bandwidth, low rate is applied, and the company to lack qualified technical personnel leads to
Frequently with NB IOT chip+MCU scheme, updated based on firmware bug and application it is generally necessary to which NB IOT and MCU require FOTA liter
Grade.The upgrading of usual NB IOT chip itself is all that chip producer has carried out, but does not all do to MCU upgrading chip producer.But
Actual scene needs MCU to upgrade, but little company lacks qualified technical personnel or without server, is unable to complete MCU upgrading.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of upgrade method for internet of things equipment MCU, small public affairs are solved
The problem of department lacks qualified technical personnel or without server, MCU scaling difficulty.
To solve the above problems, the technical solution adopted by the present invention is that: the original firmware of MCU is placed on NB IOT first
In chip；Then when NB IOT upgrades, NB IOT chip obtains respectively according to the original firmware of itself and the original firmware of MCU
Take itself firmware updating and MCU firmware updating；Last MCU chip is by instruction the firmware updating of MCU from NB IOT
It is read in chip, and then completes the upgrading of MCU.
Further, it is placed on the original firmware of MCU as C language array form in NB IOT chip.
Further, NB IOT chip is upgraded by way of FOTA.
The beneficial effects of the present invention are: the present invention uses the novel technology that is skillfully constructed, the firmware of MCU is put into NB IOT core
In piece, when NB IOT itself upgrades, while the firmware of implicit MCU has upgraded, and is then instructed using AT, and MCU is from NB IOT chip
Firmware updating is obtained, it is simply, fast, convenient, it is not necessarily to server, requirement capability is weak, does not have to use the special upgrade cost in market
Expensive professional fota upgrades company, without paying any expense.
Detailed description of the invention
Fig. 1 is the functional block diagram of embodiment.
Specific embodiment
For current NB IOT chip+MCU Internet of Things scheme, as shown in Figure 1, the firmware of MCU is put into NB by the present invention
In IOT chip, when NB IOT itself upgrades, while the firmware of implicit MCU has upgraded, and then MCU uses instruction from NB IOT core
Piece obtains firmware updating, simply, fast, convenient, is not necessarily to server, and requirement capability is weak, does not have to use the special upgrading expense in market
Upgrade company with expensive professional fota, without paying any expense.
For further the present invention will be described, illustrate with reference to embodiments.
Embodiment provides a kind of upgrade method for internet of things equipment MCU, and the original firmware of MCU is placed on NB first
In IOT chip；Then when NB IOT upgrades, NB IOT chip is according to the original firmware of itself and the original firmware point of MCU
Do not obtain itself firmware updating and MCU firmware updating；Last MCU chip is by instruction the firmware updating of MCU from NB
It is read in IOT chip, and then completes the upgrading of MCU.
When specific utilization, NB IOT chip, NB IOT can be placed on using the original firmware of MCU as C language array form
Upgraded generally by the mode of FOTA, the FOTA of usual NB IOT upgrades the service set up by NB IOT chip producer
Device is completed.When NB IOT upgrading, embodiment is implicit also to be upgraded MCU firmware, then can be instructed through AT, MCU chip
The firmware updating of MCU is obtained from NB IOT chip, and then completes the upgrading of MCU.
