And the controller is in wired connection with the wire controller and the external machine and can communicate. The indoor unit is used as a slave relative to the wire controller; the indoor unit serves as a master unit with respect to the outdoor unit. The firmware information obtained by the wire controller from the USB flash disk is transmitted to the next stage, and the firmware data of the outdoor unit is forwarded through the indoor unit. The indoor unit can also be added with a USB interface, if the indoor unit also has the USB interface, the obtained firmware data can only be used for the indoor unit and the outdoor unit, namely the firmware data is transmitted from the main to the secondary.
The outdoor unit is provided with a main control panel, and a main chip of the outdoor unit is responsible for the control logic of the outdoor unit. The outdoor unit receives data from the indoor unit, completes firmware upgrading process and is in wired connection with the indoor unit.
In this embodiment, the firmware upgrading method includes:
step S100, when a firmware upgrading instruction triggered by a wire controller is received, determining equipment to be upgraded corresponding to the firmware upgrading instruction, wherein the equipment to be upgraded comprises the wire controller, an indoor unit or an outdoor unit;
in this embodiment, when the line controller is currently connected to the external memory, the device to be upgraded, which includes the line controller, the indoor unit, or the outdoor unit, that needs to be upgraded is determined according to the firmware upgrade instruction, that is, it is determined which of the line controller, the indoor unit, or the outdoor unit the device that needs to be upgraded is currently.
In this embodiment, an operator may select a device that needs to be upgraded currently through a key of the line controller, for example, select an upgrade line controller, an upgrade indoor unit, or an upgrade outdoor unit through a key of the line controller, and if the air conditioning system includes a plurality of indoor units and/or a plurality of outdoor units, select to upgrade a certain indoor unit or outdoor unit.

Using a bin file synthesis tool, A, B, C is merged with the bootloader to generate a bin file (upgrade file), and some firmware information is added when the upgrade file is generated, the newly generated upgrade file contains the bootloader, the application (A, B, C), and the firmware information. The firmware information is some information inherent to the application program, and is used in the firmware loading process, the old firmware needs to know some information of the new firmware, and the firmware information includes the device type, the software version, the verification information and the like. Bootloader is responsible for loading and booting, managing the flash after the new firmware program is updated, and jumping to the application program (A, B, C). The device type is a feature number for each device (including the drive-by-wire, the indoor unit, and/or the outdoor unit). The software version is version information (including version number) of the software, and the software version number is upgraded while the software is upgraded. The verification information is used for verifying the integrity of the burning codes, and the burning codes are confirmed to be not damaged or maliciously modified, so that the system downtime caused by the updating error is avoided. The file names of the newly generated upgrade files may be copied in two and named as a1, B1, and C1, respectively, and then the three files are stored in an external memory such as a usb disk, and a line controller is inserted, although the file names of the newly generated upgrade files may be arbitrarily named by an operator.
Because the upgrade file comprises the corresponding device type of the upgrade device, when the target device type corresponding to the device to be upgraded is obtained, the target device type can be compared with the device types in all the upgrade files of the external memory, if the device types in all the upgrade files of the external memory have the device type consistent with the target device type, if a plurality of upgrade files corresponding to the device types consistent with the target device type exist in the device types in all the upgrade files of the external memory, determining a target upgrade file in a plurality of upgrade files corresponding to the device type consistent with the target device type, wherein the target upgrade file is a part of the upgrade files corresponding to the target device type.
