And a boot program is stored in the boot area. Booting is a means often employed when a computer begins to enter input. After the computer is started, a small amount of instructions and data are input by the device, and then other programs are input by the device, and the process is called booting. Boot loader is a program that boots an operating system, and is located on a computer or other computer application. The Boot Loader is used for starting a Boot Loader, and the Boot Loader is used for loading a Boot program. The Boot bootstrap program is mainly responsible for starting up and loading the Loader program; the Loader boot Loader is used for completing tasks such as configuring a hardware working environment and booting and loading a kernel. In this embodiment, the Boot bootstrap program stored in the Boot area of the outdoor unit/indoor unit of the air conditioner is set according to the Boot bootstrap program including the Boot bootstrap program and the Loader bootstrap Loader program, where the Boot bootstrap program is responsible for starting up and loading the Loader program of the outdoor unit/indoor unit of the air conditioner, and the Loader program is used for completing tasks such as hardware operating environment, kernel bootstrap loading, and the like of the outdoor unit/indoor unit of the air conditioner. The present embodiment may reuse the start-up boot program when the program upgrade is performed on the running program, so that the outdoor unit/indoor unit runs according to the running parameters, so as to maintain the current running state when the program upgrade is performed on the running program.
The conventional outdoor/indoor unit programs of the air conditioner generally include two types: local upgrade and remote upgrade; the local upgrade refers to upgrading the air conditioner on site by an air conditioner maintainer, and the remote upgrade refers to sending a program upgrade code to an outdoor unit/indoor unit of the air conditioner through wired/wireless network communication to complete the upgrade.
In the embodiment of the invention, after the outdoor unit/indoor unit of the air conditioner receives the upgrading instruction, the operation parameters in the current operation state are obtained, the operation parameters are stored in the RAM, then the starting guide program is controlled to read the operation parameters, the outdoor unit/indoor unit is operated according to the operation parameters, the outdoor unit/indoor unit is enabled to continuously maintain the current operation state, then the upgrading code of the operation program is received, the operation program is upgraded, the operation program is controlled to read the operation parameters after the program upgrading is completed, the outdoor unit/indoor unit is continuously operated according to the operation parameters, so that the current operation state of the outdoor unit/indoor unit is maintained, and in the upgrading process, the current operation state of the outdoor unit/indoor unit is temporarily maintained by starting the guide program, so that the outdoor unit/indoor unit cannot be stopped in the upgrading process, and the use experience and satisfaction of an air conditioner user are improved.
In an example of an application scenario of the present invention, as shown in fig. 5, an air conditioner in a certain market includes n outdoor units and m indoor units, a cloud service upgrade module is connected to an outdoor unit host (hereinafter referred to as a host), a program upgrade is currently required to be performed on an operation program of an indoor unit 1, the cloud service upgrade module may be used to send an upgrade instruction and an upgrade code of the indoor unit 1 to the host, then the host sends the upgrade instruction to the indoor unit 1, after receiving the upgrade instruction (assuming that the indoor unit 1 is currently in an operation state), the indoor unit 1 may read an operation parameter in a current operation state of the indoor unit 1, store the operation parameter in a RAM memory of the indoor unit 1, then read the operation parameter by using a start bootstrap program in a boot area of a ROM memory of the indoor unit 1, control the start bootstrap program to operate the indoor unit 1 according to the operation parameter, so as to maintain the current operation state of the indoor unit 1, then receive the upgrade code of the operation program sent by the host, perform the program upgrade to read the operation program, and after completing the upgrade of the operation program, read the operation parameter of the indoor unit 1.
Referring to fig. 1, fig. 1 is a flow chart illustrating main steps of a program upgrading method according to an embodiment of the invention. The embodiment is applied to a controller of an indoor unit/outdoor unit in a multi-split air conditioning system, the indoor unit/outdoor unit further includes a ROM memory and a RAM memory, a storage area of the ROM memory includes a user area and a boot area, the user area is used for storing an operation program of the indoor unit/outdoor unit, and the boot area is used for storing a start guide program of the indoor unit/outdoor unit, and the embodiment can perform program upgrade on the operation program in the user area through the following steps S101 to S103 shown in fig. 1 when the indoor unit/outdoor unit is in an operation state.
Step S101: and responding to the received upgrading instruction, acquiring the operating parameters of the indoor machine/outdoor machine in the current operating state, and storing the operating parameters into a preset storage area in the RAM.
In an embodiment of this embodiment, the operation parameters in the current operation state may be obtained after receiving the upgrade instruction, and for the indoor unit, the operation parameters may include an operation mode (for example, a cooling mode, a heating mode, an air supply mode, and the like) of the indoor unit, an operation temperature, a rotation speed of a fan, an opening degree of an expansion valve, a switch of a water pump, and a switch of a swing air (whether the swing air swings or not), and the like; for the outdoor unit, the operation parameters may include the rotation speed of the fan, the opening degree of the expansion valve, the frequency of the compressor, and the opening and closing of the solenoid valve, etc. And storing the operation parameters into a preset storage area in an RAM memory, and reading the parameters by using a starting guide program in the upgrading process after storing the operation parameters into a preset memory in the RAM memory so as to maintain the current operation state of the outdoor unit/indoor unit.
Step S102: and controlling a starting guide program to read the operation parameters of the indoor unit/outdoor unit in the preset storage space, and operating the indoor unit/outdoor unit according to the operation parameters so as to maintain the current operation state of the indoor unit/outdoor unit in the process of upgrading the operation program.
After the operation parameters are obtained, the operation program in the user area may stop operating the outdoor unit/indoor unit according to the operation parameters, instead, the start-up bootstrap program maintains the current operation state of the outdoor unit/indoor unit according to the operation parameters, for the indoor unit, the operation mode, the operation temperature, and the rotation speed of the fan may be maintained (assuming that the fan is an ac fan), the opening degree of the expansion valve is maintained, the on-off state of the water pump is maintained, and if the swinging air is in a swinging state, the swinging air may be stopped after swinging to a fixed angle, for example, after swinging to a preset swinging angle. For the outdoor unit, the rotation speed of the fan (assuming that the fan is an ac fan), the opening degree of the expansion valve, the frequency of the compressor, and the open/close state of each solenoid valve may be maintained. The time required by program upgrading is generally 3 minutes to 5 minutes, and in the short time, the outdoor unit/indoor unit can be continuously operated according to the operation parameters by starting the bootstrap program to maintain the current operation state, so that the outdoor unit/indoor unit can not stop operating in the upgrading process, and the use experience of an air conditioner user is further improved.
In one embodiment of this embodiment, the specific steps of "operating according to the operating parameters" include steps S201 to S203 shown in fig. 2:
step S201: judging whether the starting bootstrap program can operate the indoor unit/outdoor unit according to the operation parameters, if so, executing step S202, and if not, executing step S203;
step S202: operating the indoor unit/outdoor unit according to the operation parameters so as to enable the indoor unit/outdoor unit to maintain the current operation state in the process of upgrading the program of the operation program;
step S203: and acquiring simulation parameters corresponding to the preset operation parameters, and operating the indoor unit/outdoor unit according to the simulation parameters so as to enable the indoor unit/outdoor unit to operate in a preset operation state in the process of upgrading the program of the operation program.
For example, if a fan in the indoor unit is a direct current fan, if the direct current fan needs to operate at different rotation speeds, different voltages need to be input to the direct current fan, so that when the indoor unit normally operates, a VSP timer (which is one of operation programs and can output different voltages to control the direct current fan to operate at different rotation speeds according to gear information (for example, high, medium, and low gear positions of the fan rotation speed)) needs to be used to output different voltages to control the fan to operate at different rotation speeds. When the running program of the user area is upgraded, whether a start guiding program of the boot area contains a VSP timer for controlling the running of the direct current fan needs to be judged, if the start guiding program does not contain the VSP timer, an analog voltage can be generated according to the rotating speed of the fan corresponding to the running parameters, the fan is controlled to run at the rotating speed corresponding to the running parameters by using the analog voltage, the rotating speed of the fan is kept unchanged, and the outdoor unit/indoor unit is operated close to the current running state to the maximum extent.
Through the steps, different methods can be adopted for different operation parameters, and the outdoor unit/indoor unit is operated when the program of the outdoor unit/indoor unit is upgraded, so that the current operation state of the outdoor unit/indoor unit is maintained, or the current operation state of the outdoor unit/indoor unit is approached to the maximum extent.
Step S103: and upgrading the running program according to the received upgrading code of the running program, controlling the upgraded running program to read the running parameters of the indoor unit/outdoor unit in the preset storage space, and running the indoor unit/outdoor unit according to the running parameters so as to enable the indoor unit/outdoor unit to continuously maintain the current running state after the running program is upgraded.
In an implementation manner of this embodiment, this embodiment may further include:
and generating prompt information for temporarily interrupting communication and sending the prompt information to external equipment in communication connection with the indoor unit/the outdoor unit in the process of upgrading the running program.
When the running program of the indoor unit is upgraded, if a communication request of other equipment such as a wire controller is received, prompt information for temporarily interrupting communication can be generated and sent to the other equipment to indicate that the normal communication cannot be realized during upgrading, and the other equipment can temporarily stop communication after receiving the prompt.
For example, when the program for operating the slave outdoor unit (outdoor unit slave unit) is upgraded, a notification message for temporarily interrupting communication may be sent to a controller for controlling the operation of the compressor, the master outdoor unit (outdoor unit master unit), and the like.
When the program of the main outdoor unit (outdoor unit host) is upgraded, a prompt message for temporarily interrupting communication can be sent to all other devices controlled by the main outdoor unit (i.e. the outdoor unit, the indoor unit, the compressor, etc.).
In an implementation manner of this embodiment, this embodiment may further issue an alarm and shut down when an upgrade is abnormal through steps S301 to S302 shown in fig. 3:
step S301: when the program upgrading of the running program is abnormal, whether the communication interruption time length is greater than or equal to a preset time length threshold value is judged, if yes, the step S302 is executed, and if not, whether the communication interruption time length is greater than or equal to the preset time length threshold value is continuously judged.
Step S302: and stopping operating the indoor unit/outdoor unit according to the operation parameters and sending an alarm.
In one example, when the program of the outdoor unit/indoor unit is upgraded, if the upgrade cannot be completed within a preset time (for example, 3 minutes) due to an abnormality, that is, the duration of the communication interruption is greater than or equal to 3 minutes (that is, a time threshold), the operation of the outdoor unit/indoor unit according to the operation parameter may be stopped at this time. For the indoor unit, the expansion valve of the indoor unit may be in an open state, and operating the indoor unit with the open degree of the expansion valve in a short time may not cause a failure or affect the user experience of the air conditioner user. For the slave outdoor unit (outdoor unit sub-unit), if the communication is interrupted for too long, and the compressor is always operated at the frequency corresponding to the operation parameter during the communication interruption period, a fault may occur, or even the device may be damaged, at this time, the operation of the compressor according to the operation parameter may be stopped, and even if the compressor is stopped, for example, the operation parameter related to the frequency of the compressor may be deleted from the operation parameters in the preset storage space of the RAM memory of the slave outdoor unit to stop the operation of the compressor, at this time, the fan and the like of the slave outdoor unit may continue to be operated, or all the operation parameters in the preset storage space of the RAM memory may be deleted, the operation of the slave outdoor unit may be stopped, and an alarm may be issued. For a main outdoor unit (outdoor unit host), if an abnormality occurs for a long time, the entire multi-split air conditioning system is likely to be affected and even devices are damaged, so if upgrading cannot be completed within a preset time, the duration of communication interruption is greater than or equal to a preset time threshold (for example, 3 minutes), at this time, the operation parameters related to the frequency of a compressor can be deleted from the operation parameters in the preset storage space of the RAM memory of the main outdoor unit, the operation of the compressor is stopped, or all the operation parameters in the preset storage space of the RAM memory can be deleted, the operation of the main outdoor unit is stopped, or the communication interruption time is too long, other devices (from the outdoor unit, the indoor unit, the compressor and the like) judge that the communication interruption time is greater than or equal to the preset time threshold, all the devices stop operating, that is, and an alarm is given.
In one example, if the duration of the interrupted communication is less than a preset duration threshold (e.g., 3 minutes), the waiting may be continued and it may be determined again whether the duration of the interrupted communication is greater than the duration threshold.
In the process of upgrading the program of the outdoor unit/indoor unit, the outdoor unit/indoor unit is operated according to the operation parameters to maintain the current operation state of the outdoor unit/indoor unit, the outdoor unit/indoor unit is operated according to the operation parameters within the preset time threshold without adjusting the operation parameters, and the possibility that the outdoor unit/indoor unit breaks down or damages equipment is extremely low, so that even if the program upgrading of the operation program is abnormal, only the judgment is needed to be made as to whether the communication interruption time is greater than or equal to the preset time threshold, if the abnormity can be removed and the upgrading can be completed within the preset time threshold, the operation of the outdoor unit/indoor unit according to the operation parameters is not needed to be stopped, if the abnormity cannot be removed and the upgrading can be completed within the preset time threshold, and if the outdoor unit/indoor unit is continuously operated according to the operation parameters, the outdoor unit/indoor unit is likely to break down or damage the equipment, the operation of the outdoor unit/indoor unit according to the operation parameters is needed to be stopped and an alarm is sent.
Based on the steps S101 to S103, the outdoor unit/indoor unit can be continuously operated according to the operation parameters when the operation program of the outdoor unit/indoor unit is upgraded, so that the outdoor unit/indoor unit maintains the current operation state, and the use experience and satisfaction of the air conditioner user are further improved.
