In some embodiments, as shown in fig. 5, a schematic structural diagram of communication between an indoor unit and an outdoor unit according to an embodiment of the present invention is shown. The indoor unit control parameter rewriting information is used for rewriting indoor unit control parameters, indoor control parameter rewriting information required to be rewritten can be extracted, the rewriting information is temporarily stored in a second storage space of the indoor controller, the indoor control parameters are temporarily rewritten through the rewriting information, the temporary rewriting is effective at this time, and when the air conditioner is powered on again after the power failure, the air conditioner control parameters are restored to the control parameter setting when the air conditioner leaves the factory.
Or, as shown in fig. 5, when the indoor unit control parameter is rewritten, the rewritten information of the indoor unit control parameter is obtained, and the rewritten information of the indoor unit control parameter is temporarily stored in the first storage space of the indoor controller, the indoor control board reads the original indoor control parameter of the E-side memory 1 through I2C communication, and temporarily stores the original indoor control parameter in the second storage space of the indoor controller, the indoor control board rewrites the original indoor control parameter in the second storage space according to the rewritten information of the indoor control parameter stored in the first storage space, for example, rewrites the address corresponding data in the second storage space according to the address corresponding data in the first storage space, and recalculates the checksum of the second storage space, the rewritten signal of the indoor control board controlling the E-side memory 1 is set to low level, the control parameter in the second storage space after passing through I2C communication, and sending the control parameters to the E-side memory 1 to realize the writing of the indoor unit control parameters, and controlling the indoor unit to operate according to the written control parameters, wherein the read-write signal of the E-side memory 1 is default to high level, so that the E-side memory 1 can only read and can not write.
In some embodiments, as shown in fig. 5, when the outdoor control parameter is rewritten according to the outdoor control parameter rewriting information, it is first determined whether the shutdown instruction is completed, for example, whether the compressor is stopped, whether the outdoor fan is stopped, and whether the electronic expansion valve is stopped, when the shutdown instruction is completed, the outdoor control parameter rewriting information is temporarily stored in the fourth storage space of the outdoor controller, the indoor control parameter is temporarily rewritten by the rewriting information, the temporary rewriting is valid this time, and when the air conditioner is powered on again after the power failure, the air conditioner control parameter is restored to the control parameter setting when the air conditioner is shipped.
Or, when rewriting the outdoor control parameter, the outdoor control board analyzes the rewriting information of the outdoor control parameter, extracts the storage address and corresponding data of the control parameter to be rewritten in the rewriting information, and stores the extracted storage address and corresponding data in the third storage space of the outdoor controller, the outdoor control board reads the original outdoor control parameter in the E-side memory 2 through I2C communication and temporarily stores the original outdoor control parameter in the fourth storage space of the outdoor controller, the outdoor control board rewrites the original outdoor control parameter in the fourth storage space according to the rewriting information of the control parameter in the third storage space and recalculates the checksum of the array in the fourth storage space, the read-write signal of the outdoor control board controlling the E-side memory 2 is set to low level, the address and data of the rewritten fourth storage space are written in the outdoor memory, i.e. the E-side memory 2 through I2C communication, and writing in control parameters of the indoor unit is realized, and the outdoor unit is controlled to operate according to the written control parameters, wherein the read-write signal of the E-side memory 2 is default to high level, so that the E-side memory 2 can only read and can not write.
In some embodiments, after the writing of the indoor unit control parameter is completed, the written control parameter needs to be verified, the read-write signal of the indoor control board control E-side memory 1 is set to a high level, the rewritten indoor control parameter written in the indoor memory is rewritten and read through I2C communication, and the rewritten indoor control parameter written in the indoor memory is verified, if the verification is correct, a successful rewriting prompt of the indoor control parameter is performed, for example, a buzzer sounds 5, a user hears a buzzer 5, and can determine that the rewriting of the indoor control parameter is successful, or, if the verification is incorrect, a failed rewriting prompt of the indoor control parameter is performed, for example, a buzzer sounds 1, and a user hears a buzzer 1, and can determine that the rewriting of the indoor control parameter is failed. And whether the current control parameter is successfully rewritten can be displayed on a nixie tube arranged in the indoor unit, and a user can determine whether the current control parameter is successfully rewritten by observing the display information of the nixie tube of the indoor unit.
In some embodiments, after the rewriting of the outdoor unit control parameter is completed, the read-write signal of the outdoor control board controlling the E-side memory 2 is set to a high level, the rewritten outdoor control parameter written in the outdoor memory, i.e., the E-side memory 2, is rewritten and read through the I2C communication, the rewritten outdoor control parameter written in the rewritten and read outdoor memory is verified, and when the verification is correct, it is determined that the rewriting of the outdoor unit control parameter is successful, and then a successful rewriting signal of the outdoor control parameter is fed back to the indoor unit.
When the indoor unit control parameters are temporarily rewritten, after the indoor control parameters are temporarily rewritten, a temporary rewriting completion prompt is performed according to the result of temporarily rewriting the indoor control parameters, and because the number of prompt sounds emitted when the temporary rewriting control parameters are successful and the temporary rewriting control parameters are failed is different, whether the current control parameters are successfully rewritten or not can be determined according to the different number of prompt sounds; when the control parameter of the outdoor unit is rewritten, the indoor unit sends the rewriting information of the outdoor control parameter to the outdoor unit through indoor and outdoor two-way communication, if the transmission is successful, the buzzer sounds for 1 sound, if a feedback signal of successful rewriting of the control parameter of the outdoor unit is received, the buzzer successfully prompts, for example, the buzzer sounds for 6 sounds, and the buzzer sends out different numbers of prompting sounds to determine the rewriting process of the outdoor control parameter.
In some embodiments, when the indoor unit rewrites the indoor unit control parameter or the outdoor unit control parameter after receiving the air conditioner control parameter rewriting information, the indoor unit receives a control parameter rewriting signal, first controls the indoor unit and the outdoor unit to execute a shutdown instruction, and sends an outdoor shutdown instruction to the outdoor unit, controls the indoor fan to pause, controls the indoor fan to close, rewrites the control parameter, for example, displays a flag in parameter rewriting, such as a display PO flag, of the indoor unit, and prepares in advance for rewriting the indoor unit control parameter.
