In the related art, when the air conditioner is upgraded, the original program cannot normally run, so that the running function of the air conditioner is forced to be stopped, the effect achieved by the function is influenced or even disappears, and the comfort and the use experience of a user are poor. For example, if the air conditioner normally starts program upgrading in the process of refrigeration, the refrigeration program is stopped, so that refrigeration cannot be performed in the process of program upgrading, the indoor air temperature rises, the comfort of a user is deteriorated, and the use experience is correspondingly reduced.

Based on this, in a first aspect, at least one embodiment of the present disclosure provides a program upgrading method for an air conditioner, please refer to fig. 1, which illustrates a flow of the method, including step S101 and step S103.

The program upgrading method of the air conditioner is applied to the air conditioner, and specifically can be applied to a main control board of the air conditioner or an MCU (micro controller Unit) special for the method. The air conditioner comprises a memory, wherein the memory comprises a first storage area and a second storage area, the first storage area is internally stored with an original program file, the main control board can read the original program file from the storage area and operate the original program file, so that the operation of each function of the air conditioner can be realized, the second storage area is marked as an idle storage area, and no file is stored in the storage area.

The program upgrade refers to the Air conditioner downloading the latest version of the program file from the server using an Over-the-Air Technology (OTA).

In step S101, a program upgrade instruction is received, and a download request is sent to a server according to the program upgrade instruction, where the download request is used to download a program file of a latest version.

The upgrading instruction can be sent by the server, namely when the version of the program file existing in the server is updated compared with the version of the program file in the air conditioner, the upgrading instruction can be sent to the air conditioner; the upgrading instruction can also be sent by a remote controller, namely, a user operates the remote controller to generate the upgrading instruction and sends the upgrading instruction to the air conditioner through infrared and other media; the upgrade instruction may also be generated by a remote control program of the air conditioner, for example, a user operates a terminal device running the remote control program of the air conditioner to generate the upgrade instruction, and the upgrade instruction is transmitted to the air conditioner through a medium such as bluetooth or a wireless network. The air conditioner may thus receive at least one of the following program upgrade instructions: receiving a program upgrading instruction sent by the server; receiving a program upgrading instruction sent by a remote controller; and receiving a program upgrading instruction sent by the terminal equipment running the remote control program of the air conditioner.

In one example, the air conditioner has an indoor unit and an outdoor unit, and the receiving of the program instruction in this step may mean that the indoor unit receives a program upgrade instruction. The indoor unit is generally installed indoors, the outdoor unit is generally installed outdoors, and when a user controls the air conditioner, the user often sends a control instruction to the indoor unit, for example, the user sends a start instruction, a refrigeration instruction, a temperature setting instruction, a shutdown instruction and the like to the indoor unit through a remote controller, and then, for example, the user sends the start instruction, the refrigeration instruction, the temperature setting instruction, the shutdown instruction and the like to the indoor unit through a terminal device running a remote control program of the air conditioner; and the indoor unit is easy to access the network indoors, so that the indoor unit is convenient to receive the control command sent by the server. The indoor unit and the outdoor unit can communicate with each other and transmit files, so that the indoor unit can trigger the program upgrading of the indoor unit and the outdoor unit at the same time after receiving the program upgrading instruction, the efficiency of triggering upgrading is improved, and response delay caused by unstable communication of the outdoor unit is avoided.

After receiving the download request, the server returns the program file of the latest version according to the transmission path of the download request.

In step S102, the program file of the latest version is saved into the second storage area.

When the program file with the latest version is downloaded, the storage address can be determined by identifying the mark of the idle storage area, so that the method is simple, convenient, accurate and reliable. The original program file is normally operated, the program file of the latest version is downloaded to the server at the same time, and the program file of the latest version is stored in the second storage area, namely the first storage area for storing the original program file is not influenced, and further the normal operation of the original program file is not influenced.

In step S103, if the program file of the latest version is downloaded completely and the air conditioner is in the target state, the program file of the latest version is executed, the original program file stored in the first storage area is deleted, and the first storage area in which the original program file is deleted is marked as an idle storage area.

The target state may be a standby state or a state of less power operation, among others. When the air conditioner is in a standby state, the original program file can be directly deleted, and the program file with the latest version can be operated when the air conditioner is started next time; when the air conditioner is in a low-frequency and low-power state, the air conditioner can be shut down firstly, then the original program file is deleted, and the program file of the latest version is operated after the air conditioner is restarted. The standby state does not perform any function, so that the effect of the function is not influenced; when the low-frequency low-power running is performed, the effect achieved by the running function is basically stable, and only the program file is replaced after the running is stopped (namely, the time for downloading the program file does not exist), so that the required time is short, the effect of the air conditioner is less influenced, the comfort of a user during program upgrading is improved, and the use experience of the user is improved.

And marking the first storage area deleted with the original program file as an idle storage area, namely transferring the mark of the idle storage area to the first storage area for storing the original program file, so that the function exchange of the two storage areas is completed, and therefore, a new idle storage area (namely the first storage area) can be used for storing the program file with an updated version when the program file is updated next time.

In addition, before the program file of the latest version is executed, the program file of the latest version may be checked, and the program file of the latest version may be executed if the check is successful. Specifically, a Cyclic Redundancy Check (CRC) mode may be used to Check the program file of the latest version, that is, a Cyclic Redundancy Check value is calculated according to the program file, and then the Cyclic Redundancy Check value carried in the program file is obtained, and if the two Cyclic Redundancy Check values are the same, the Check is successful. Through verification and then operation of the program file, the correctness of the program file can be ensured, and therefore all functions of the air conditioner can operate normally after the program file is operated.

The present disclosure sets a first storage area and a second storage area in a memory of an air conditioner, stores an original program file in the first storage area, marks the second storage area as a restricted storage area, therefore, after receiving the program upgrading instruction, the original program file is normally operated, the program file with the latest version is downloaded to the server, the program file with the latest version is stored in the second storage area, namely, the first storage area for storing the original program file is not influenced, and further the normal operation of the original program file is not influenced, and finally, when the program file of the latest version is downloaded and the air conditioner is in the target state, the program file of the latest version is operated, and then finishing the program upgrade, additionally deleting the original program file, and marking the emptied first storage area for storing the original program file as an idle storage area so as to store the program file with the updated version in the next upgrade. In the process of program upgrading for one time, the two storage areas are alternately used as the storage area for storing the original program file and the idle storage area, so that the program file of the latest version can be downloaded under the condition of not influencing the operation of the original program file every time the program is upgraded, the normal operation of the air conditioner is prevented from being influenced by the program upgrading, the comfort of a user during the program upgrading is improved, and the use experience of the user is improved.

In some embodiments of the present disclosure, an air conditioner includes an indoor unit and an outdoor unit, the indoor unit includes an indoor unit memory, the indoor unit memory includes a first indoor unit storage area and a first indoor unit storage area, an original indoor unit file in an original program file is stored in the first indoor unit storage area, and the second indoor unit storage area is marked as an idle indoor unit storage area; the outdoor unit comprises an outdoor unit memory, the outdoor unit memory comprises a first outdoor unit storage area and a second outdoor unit storage area, original outdoor unit files in original program files are stored in the first outdoor unit storage area, and the second outdoor unit storage area is marked as an idle outdoor unit storage area. Based on the above structure, after receiving the program upgrading instruction, the indoor unit of the air conditioner provided by the present application may upgrade the program according to the method shown in fig. 2, including steps S201 to S203.

In step S201, the indoor unit sends an indoor unit download request to the server, where the indoor unit download request is used to download an indoor unit file in the program file of the latest version, and the outdoor unit sends an outdoor unit download request to the server, where the outdoor unit download request is used to download an outdoor unit file in the program file of the latest version.

The indoor unit may have a first wireless transmission module in a wireless network accessed to an environment, so that in this step, an indoor unit download request may be sent to the server through the first wireless transmission module, where the indoor unit download request is used to download the indoor unit file in the program file of the latest version through the first wireless transmission module.

The outdoor unit is provided with a second wireless transmission module in a wireless network accessed into the environment, so that an outdoor unit downloading request can be sent to the server through the second wireless transmission module in the step, and the outdoor unit downloading request is used for downloading an outdoor unit file in the program file of the latest version through the second wireless transmission module.

The outdoor unit is provided with a second wireless transmission module, the second wireless transmission module is connected to a wireless network in an environment through pairing with the first wireless transmission module, so that an outdoor unit downloading request can be sent to the server sequentially through the second wireless transmission module and the first wireless transmission module in the step, and the outdoor unit downloading request is used for downloading an outdoor unit file in the program file of the latest version sequentially through the second wireless transmission module and the first wireless transmission module. In this way, the first wireless transmission module can transfer the program file when the second wireless transmission module downloads the program file, and the program file is not downloaded to the indoor unit.

The first wireless transmission module of the indoor unit can be accessed into a wireless network in an environment according to the following modes: the user uses the remote controller to reset the first wireless transmission module so as to enable the first wireless transmission module to be in a broadcasting state; a user downloads a remote control program of the air conditioner on terminal equipment, then the remote control program is used for scanning a two-dimensional code on an indoor unit of the air conditioner so as to realize Bluetooth connection with the first wireless transmission module, then the remote control program controls the first wireless transmission module to search an indoor wireless network, correct passwords are input after the networks are searched, and information such as account numbers and passwords of the wireless network is sent to the first wireless transmission module, so that the first wireless transmission module is accessed into the wireless network by using the account numbers and the passwords.

The second wireless transmission module of the outdoor unit can be accessed into the wireless network in the environment in the following way: the user uses the remote controller to reset the second wireless transmission module so as to enable the second wireless transmission module to be in a broadcasting state; a user downloads a remote control program of the air conditioner on terminal equipment, then the remote control program is used for scanning a two-dimensional code on an outdoor unit of the air conditioner so as to realize Bluetooth connection with the second wireless transmission module, then the remote control program controls the second wireless transmission module to search an indoor wireless network, correct passwords are input after the networks are searched, and information such as account numbers and passwords of the wireless network is sent to the second wireless transmission module, so that the second wireless transmission module is accessed into the wireless network by using the account numbers and the passwords. If the remote control program controls the second wireless transmission module not to search the wireless network in the environment, the second wireless transmission module is continuously controlled to search the first wireless transmission module and is paired after the first wireless transmission module is searched, so that the wireless network in the environment is accessed through the first wireless transmission module.

In step S203, controlling the indoor unit to run the indoor unit file, deleting an original indoor unit file stored in the first indoor unit storage area, and marking the first indoor unit storage area where the original indoor unit file is deleted as an idle indoor unit storage area; and controlling the outdoor unit to operate the outdoor unit files, deleting original outdoor unit files stored in the first outdoor unit storage area, and marking the first outdoor unit storage area deleted with the original outdoor unit files as an idle outdoor unit storage area.

Details of this step have already been described in detail in step S103, and are not repeated here.

In some embodiments of the present disclosure, whether the air conditioner is in the target state may be determined as follows: firstly, acquiring a control instruction acquired by a main control board of an air conditioner; next, if the latest command in the control commands is a shutdown command, determining that the air conditioner is in a target state; next, if the latest instruction in the control instructions is a non-shutdown instruction, acquiring the ambient temperature acquired by a temperature sensor, and determining the set temperature of the air conditioner according to the control instructions; and finally, if the ambient temperature is lower than a temperature threshold, determining that the air conditioner is in a target state, wherein the temperature threshold is equal to the set temperature or is higher than the set temperature by a preset temperature difference value.

The main control board controls the operation of the air conditioner, and generates control instructions, such as a power-on instruction, a power-off instruction, a temperature setting instruction, an operation mode setting instruction and the like, in the control process, so that the control instructions can be obtained from the main control board, the obtained control instructions can represent the operation state of the air conditioner at the moment to a certain extent, and for example, if the latest control instruction is a power-off instruction, the air conditioner is in a standby state at the moment. Some states of the air conditioner cannot be accurately determined by using the control command, so that the states can be further determined according to the ambient temperature. The air conditioner may be provided with a temperature sensor, for example, a temperature sensor provided on the indoor unit, and the temperature sensor may collect an indoor ambient temperature and report the collected temperature to the main control board, so that the ambient temperature may be acquired from the main control board.

If the latest control instruction is a shutdown instruction, it indicates that the air conditioner is in a standby state at present, that is, a state in which no function is operated, and therefore, there is no situation that the operation of the air conditioner is affected when the program is upgraded in the state (that is, the operation of the original program file is stopped and the operation of the program file of the latest version is started), and there is no situation that the comfort and the user experience are affected, so that the standby state is determined as the target state.

When the latest control instruction is a non-shutdown instruction, the air conditioner is in a certain function of operation, such as cooling, heating and the like, that is, the air conditioner is not in a standby state, so that whether the air conditioner is in a low-frequency low-power state or not can be further determined.

The set temperature represents the temperature that the user wants the environment to reach, and the temperature threshold represents the temperature range that the user can accept, so when the ambient temperature is lower than the temperature threshold, it represents that the temperature effect that the present air conditioner reaches is close to the temperature that the user wants, or the temperature difference between the temperature effect that the air conditioner reaches and the set temperature is in the user acceptable range, so the air conditioner is in the stable stage or the fine tuning stage at this moment, namely in the state of low frequency and low power.

The temperature threshold range may be preset in advance, for example, set to the set temperature itself, or set to the set temperature +1 ℃. For example, when the set temperature is 24 ℃ and the temperature threshold is the set temperature itself, when the ambient temperature is lower than 24 ℃, the low-frequency and low-power state is determined; for another example, when the set temperature is 24 ℃ and the temperature threshold is +1 ℃, when the ambient temperature is lower than 25 ℃, the low-frequency and low-power state is determined.
