And S4, operating the software information area, updating the software version information and the corresponding application program area entry address in the FLASH.
And S5, the lower computer reads the software version information in the software information area and the corresponding application program entry address, and jumps to the corresponding application program area to operate, so as to realize the remote online update of the software version.
Wherein S3 further includes:
s31, the upper computer analyzes the software updating program file to form a plurality of data packets, and sends a software downloading instruction containing a programming command frame and a data frame;
and S32, the lower computer receives the programming command frame and the data frame sent by the upper computer, writes the corresponding programming data information into the application program area of the corresponding address after receiving a data packet, and sends the response information of successful programming.
And after the lower computer finishes software updating, actively updating the software version information and the corresponding application program area entry address in the FLASH, then sending a version updating finishing instruction to the upper computer, and after receiving the version updating finishing instruction sent by the lower computer, sending a version switching instruction to the lower computer by the upper computer. And after receiving the software version switching instruction, the lower computer jumps to the Flash address of the new version and starts to work by using the software of the lower computer of the new version.
After the chemiluminescence analyzer is powered off and restarted, the BootLoader program jumps to (on a Flash instruction position) the Flash address of the application program updated last time to start execution.
In this embodiment, the upper computer and the lower computer may be connected via a CAN bus, a SPI, an SCI bus, or an RS232, an RS485, an IIC, a network, or the like.
Software version upgrading principle: (1) major version numbers, functional modules have large variations, such as adding multiple modules or changes in the overall architecture. (2) Minor version numbers, as opposed to major versions, are only local changes to upgrades of minor version numbers. However, the local change causes the program to be incompatible with the previous version, or causes a damage to the previous collaboration of the program, or causes a great improvement or enhancement in the function. (3) Revision version number: the local change is mainly the function improvement of the local function, or the correction of the bug, or the expansion of the function. In principle, revision version numbers will change frequently after release from the first stable version, whereas minor version numbers will change as the case may be, with major version numbers changing less frequently unless there is a major reconfiguration or functional improvement.
