Currently, with the updating and development of technology, firmware upgrade of various data acquisition modules is often required. The original upgrading method is one-to-one upgrading, and time and energy are consumed in modes of downloading and burning through a PC (personal computer). Later on-line upgrading occurs, but the on-line upgrading fault-tolerant capability in the prior art is poor, once upgrading fails, a program can be damaged, on-line upgrading cannot be performed again, and only burning can be performed through dismantling. In addition, in the case of burning, data such as the original setting parameters and the like are removed, so that the data need to be operated again, and the efficiency is low. In view of this, the present application provides a method for upgrading firmware of a data acquisition module, which can effectively solve the above problems.

s101: and after receiving the upgrade command, executing a preset upgrade instruction in the currently running firmware code so as to overwrite the acquired firmware code with the new version number into the standby APP space block.
The currently running firmware code is the firmware code stored in the main APP space block.
Specifically, referring to fig. 2, fig. 2 is a schematic view of a storage space of a data acquisition module disclosed in the embodiment of the present application.
Specifically, the storage space of the data acquisition module is divided into a plurality of space blocks, including two APP space blocks and a bootstrap space block. The data acquisition module comprises a plurality of APP space blocks, wherein each APP space block is stored with a firmware code of the data acquisition module, and the data acquisition module can realize application program functions such as data acquisition by running the firmware code.
It should be noted that, of the two APP space blocks, one is a main APP space block, and the other is a standby APP space block. The data acquisition module reads a firmware program from the main APP space block by default and operates the firmware program; during a non-firmware upgrade, the standby APP space block is used to store a copy of the firmware program in the primary APP space block in order to achieve fault tolerance protection. Therefore, in general, the firmware code that normally runs after booting is the firmware code stored in the main APP space block.
The boot space block has a boot stored therein. As will be understood by those skilled in the art, a boot program is a program that automatically runs on a device upon power up to boot and load firmware code to initiate operation of the data collection module.

Therefore, further, the determining, by the bootstrap program, whether the upgrade is successful may specifically include:
reading the mark quantity of a preset mark bit; in the execution process of the preset upgrading instruction, if upgrading is overtime or error is reported, the preset mark quantity is set as a first mark quantity; otherwise, setting the preset mark quantity as a second mark quantity; and judging whether the upgrading is successful according to the read mark quantity.
For example, the first flag amount may be specifically 1, which represents an upgrade failure; the second flag amount may be specifically 2, which represents that the upgrade is successful.
S104: and overwriting the firmware code in the standby APP space block into the main APP space block.
After the upgrade is finished, if the upgrade is judged to be successful by running the bootstrap program, the firmware code in the standby APP space block is the firmware code of the new version number, and the other APP space block, namely the main APP space block, can be written in a covering manner.
S105: and reporting an upgrade ending response message corresponding to the upgrade result.
Furthermore, after step 105, the preset flag may be set to a default third flag, for example, 3, to indicate a non-upgrade status.
