Fig. 4 is a flowchart of a software upgrading method for an air conditioner according to an embodiment of the present disclosure. The method is performed by the terminal 10, the air conditioner control panel 21 and the compressor controller 23 in fig. 1, and referring to fig. 4, the method includes:
s41: and the terminal and the air conditioner control panel establish Bluetooth connection.
In the embodiment of the disclosure, the terminal establishes a bluetooth connection with the air conditioner control panel through the wechat applet.
S42: and the terminal determines the software version information of each embedded device.
And the terminal acquires the software version information of each embedded device from the air conditioner control panel.
In one possible implementation, the software version information may be stored in a controller parameter area of the air conditioner control panel. And after the Bluetooth connection is established, the air conditioner control panel sends the software version information in the controller parameter area to the terminal.
The software version information comprises software versions of an air conditioner control panel, an air conditioner system controller and a compressor controller, wherein the software versions of the air conditioner system controller or the compressor controller can be recorded when the air conditioner control panel assists the air conditioner system controller or the compressor controller to carry out software upgrading, or can be acquired by the air conditioner control panel and the air conditioner system controller or the compressor controller in an interactive mode. The software version may be obtained from software data at the time of the software upgrade.
S43: and the terminal determines an update target based on the software version information of each embedded device.
After the terminal inquires the software version information, the software version information is compared with the latest software version of each device in the terminal to determine whether the software version information is different. If the two are completely consistent, updating is not needed, and the flow is ended.
If the software versions are not completely consistent, determining the equipment with inconsistent software versions, and determining the equipment as an update target. It should be noted that the number of the determined update targets may be 1, 2, or 3, and when the number is greater than 1, the subsequent update processes are updated one by one, that is, the processes of the subsequent steps S44-S51 are required to be performed for updating each target.
S44: the terminal sends an erasing command to the air conditioner control panel; the air conditioner control panel receives the erase command.
S45: and the air conditioner control panel erases the data in the control parameter area and the update program backup area based on the erasing command.
When the air conditioner control panel executes the erasing command, the software executing the erasing records whether the erasing is successful, and when the erasing is successful, the air conditioner control panel sends an erasing success indication to the terminal to inform the terminal of successful erasing; and when the erasing fails, the air conditioner control panel sends an erasing failure indication to the terminal to inform the terminal of the erasing failure.
S46: and when the air conditioner control panel is successfully erased, the terminal sends an update target parameter, an updated file length and an update starting command to the air conditioner control panel. The air conditioner control panel receives the update target parameter, the updated file length and the update start command, and stores in the control parameter area.
As described above, after the update target is determined, the Hex file corresponding to the update target is determined, and the updated file length is the length of the Hex file.
Optionally, after receiving the update start command, the air conditioner control panel enters an update mode, and indicates the user through an update identifier on the panel, for example, displaying an "UP" word.

Illustratively, the software data includes a plurality of lines of code, and the sending the software data includes:
and sending the plurality of lines of codes to the air conditioning system controller or the compressor controller line by line, and sending the next line of codes after each line of codes is successfully sent.
In the embodiment of the disclosure, each time the air conditioner control panel receives a line of codes, a receiving success identifier is sent to the terminal once, and the terminal sends the next line of codes after receiving the receiving success identifier. If the terminal does not receive the successful receiving identifier after the set time (for example, 30 seconds), the code sent last time is repeatedly sent, if the successful receiving identifier is not received for a plurality of times (for example, 10 times), the bluetooth is disconnected or the air conditioner control panel is powered off, at this moment, the process is ended, and the WeChat applet of the terminal can output an update failure prompt.
If the air conditioner control panel does not receive the code for more than a set time (for example, 30 seconds), sending a receiving failure identifier to the terminal, and if the receiving failure identifier is continuously sent for multiple times (for example, 10 times), ending the process and exiting the updating mode.
S48: when the software data is sent, the terminal sends a transmission ending identifier to the air conditioner control panel; the air conditioner control panel receives the transmission ending mark and stores the transmission ending mark in the control parameter area.
S49: and after the transmission is finished, the air conditioner control panel determines whether the update target is the air conditioner control panel or not based on the update target parameter.
The air conditioner control panel periodically checks the control parameter area, and when the transmission end flag is checked in the control parameter area, step S49 is executed. And at the moment, the position of the update target parameter stored in the controller parameter area inquired by the air conditioner control panel determines the update target based on the update target parameter.
When the update target is the air conditioner control panel, step S50 is performed. When the update target is the air conditioning system controller or the compressor controller, step S51 is performed.
Optionally, the method further comprises:
when the update target is the air conditioner control panel and the air conditioner is powered on again, whether the transmission of the software data is finished or not is judged again; and under the condition that the transmission of the software data is finished, whether an update target is the air conditioner control panel is judged again.
The air conditioner is powered on again, which may be operated by a user or generated by accident, and then jumps to a Bootloader program after being powered on again, and then judges whether transmission is finished and updates the target.
S50: and the air conditioner control panel adopts the software data to upgrade the software of the air conditioner control panel.
And if the update target is the air conditioner control panel, the air conditioner control panel jumps back to the Bootloader, the software data in the update program backup area is copied to the application program area in the Bootloader, and the software data is transferred to the application program area after the copying is finished, so that the software update and the upgrade of the air conditioner control panel are finished.
S51: and the air conditioner control panel sends the software data to the compressor controller so that the compressor controller can be upgraded based on the software data.
If the update target is the compressor controller, the air conditioner control panel jumps back to the Bootloader, and the software data stored in the update program backup area is sent to the compressor controller through LIN communication in the Bootloader hollow control panel, so that the software of the compressor controller is updated and upgraded.
The detailed process of step S50 will be described below with reference to fig. 5. Fig. 5 is a software upgrading flowchart of an air conditioner control panel provided in an embodiment of the present disclosure. The method is performed by an air conditioner control panel, and referring to fig. 5, the method includes:
s61: and erasing the software data in the application program area.
Software in the air conditioner control panel for erasing records whether the erasing is successful.
S62: copying the software data in the updater backup area to the application area.
When copying, the codes in the software data are copied into the application program area line by line. Each copy of a row requires determining whether the copy was successful, and whether the copy was successful. The software performing the copy in the air conditioner control panel records whether the copy is successful, and in this step, determining whether the copy is successful includes: firstly, determining whether the copying is successful or not based on the record of the software for executing copying, reading the line of codes into a cache and comparing the line of codes with corresponding codes in an updating program backup area when the record of the software for executing copying indicates that the copying is successful, if the line of codes is completely consistent with the corresponding codes in the updating program backup area, the copying is successful, otherwise, the copying fails.
In the above copying process, the amount of code that has been copied is recorded by a counter, and copying ends when the value of the counter and the updated file length are equal.
S63: it is determined whether the erasure and the copy are successful. When the erasing and copying are successful, step S64 is performed; when the erasing and copying are unsuccessful, step S65 is performed.
When one of the erasure and the copy is unsuccessful, the erasure and the copy are not successful, and when both the erasure and the copy are successful, the erasure and the copy are successful.
S64: and jumping to the application program area and running the software data in the application program area.
In addition to jumping to the application area when the erasure and copy are successful, the update flag may be reset, for example, no longer indicating to the user on the panel by the update flag, for example, no longer displaying the "UP" word.
S65: the number of erasures and duplications is determined.
Here, the number of times of erasing and copying means the number of times of erasing repetition and the number of times of repetition in copying, which is larger. For example, one erasure, three copies, the number of erasures and copies is 3.
In the present disclosure, the number of times of repetition of each action is recorded by a corresponding counter, for example, the number of times of repetition of erasing is recorded by using one counter.
S66: and when the times of erasing and copying do not exceed the threshold value, judging whether the transmission of the software data is finished again.
Illustratively, the threshold is 3 times.
And when the times of erasing and copying exceed the threshold value, the air conditioner control panel stays in the Bootloader program, and the updating is finished. At the moment, the air conditioner control panel can also feed back a software upgrading failure message of the air conditioner control panel to the terminal, so that a user can conveniently overhaul hardware.
S67: and under the condition that the transmission of the software data is finished, whether an update target is the air conditioner control panel is judged again.
When the update target is the air conditioner control panel, step S50 is performed. When the update target is the air conditioning system controller or the compressor controller, step S51 is performed.
The detailed process of step S51 will be described below with reference to fig. 6. Fig. 6 is a flow chart of software upgrade of a compressor controller according to an embodiment of the present disclosure. The method is performed by an air conditioner control panel and a compressor controller, and referring to fig. 6, the method includes:
s71: and the air conditioner control panel and the compressor controller are used for handshaking.
Illustratively, the handshaking between the air conditioner control panel and the compressor controller comprises: the air conditioner control panel sends a handshake command to the compressor controller, and the compressor controller receives the handshake command and returns a handshake response.
For example, if the air conditioner control panel receives the handshake response, it is determined that the handshake is successful, and then step S72 is executed; and if no handshake response is received, determining that the handshake fails and retransmitting the handshake command. If multiple (e.g., 3) handshakes fail, communication with the compressor controller is interrupted and the refresh mode is exited.
S72: and after the handshaking is successful, the air conditioner control panel sends an erasing command. The compressor controller receives the erase command.
S73: the compressor controller erases the software data in the application area.
The manner in which the compressor controller erases and determines whether the erasure is successful is the same as that of the air conditioner control panel, and refer to step S45.
S74: the compressor controller sends an erasing success indication after the application program area is successfully erased; the air conditioner control panel receives an erase success indication.
For example, if the air conditioner control panel receives the erase success indication, it determines that the application program area is successfully erased, and then step S74 is executed; and if the erasing success indication is not received, determining that the erasing is failed, and retransmitting the erasing command. If multiple (e.g., 3) erasures fail, communication with the compressor controller is interrupted and the refresh mode is exited.
S75: after the software data in the application program area are successfully erased, the air conditioner control panel sends the software data; the compressor controller receives the software data and stores it in the application area.
The manner of transmitting the software data and whether the transmission of the software data is successful or not by the air conditioner control panel is the same as that of the terminal, and refer to step S47.
S76: after the software data is successfully sent, the air conditioner control panel sends an updating ending command; the compressor controller receives the update end command.
Exemplarily, the air conditioner control panel determines that one row of codes is successfully transmitted when receiving the successful receiving identifier, and transmits the next row of codes until all codes are completely transmitted; if the receiving success identification is not received, the line code is failed to be sent, and the line code is sent again. If sending a row of codes multiple times (e.g., 3 times) fails, communication with the compressor controller is interrupted and the update mode is exited.
S77: after the updating ending command is successfully sent, the air conditioner control panel sends a jump command; the compressor controller receives the jump command.
For example, if the air conditioner control panel receives the reception success indication of the update end command, it determines that the update end command is successfully transmitted, and then step S77 is executed; and if the receiving success indication of the updating end command is not received, determining that the updating end command fails to be sent, and resending the updating end command. If sending the update-complete command fails multiple times (e.g., 3 times), communication with the compressor controller is interrupted and the update mode is exited.
S78: the compressor controller jumps to the application area and runs the software data therein.
For example, if the air conditioner control panel receives a successful receiving indication of the jump command, it is determined that the jump command is successfully sent, and the air conditioner control panel may reset the update identifier, for example, no longer indicate the user through the update identifier on the panel, for example, no longer display the word "UP", and exit the update mode;
