Problems solved by technology
[0003] After the air conditioner is installed, sometimes it is necessary to change the data in the outdoor EEPROM chip of the air conditioner due to various factors such as product upgrades, quality improvement, and special customization. The distance from the ground is relatively high. Open the electrical box of the outdoor unit directly to change the data in the outdoor EEPROM, which is difficult to operate and has a high potential safety hazard.

Embodiment Construction
[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0048]It should be noted that the indoor unit and outdoor unit of most split-type air conditioners generally include CPU chips and EEPROM chips. The indoor unit and the outdoor unit transmit data information to each other through a certain communication method, and the control of the indoor unit There is a remote control receiving head on the board, which can be used to receive remote control data. Therefore, for this type of air conditioner, you can use a special r...

The invention discloses a method and device for updating data in an air conditioner outdoor EEPROM and a storage medium. The data updating method comprises the steps: judging whether an indoor unit ofan air conditioner enters a rewritable state or not; when the indoor unit enters a rewritable state, obtaining outdoor EEPROM data; verifying the outdoor EEPROM (Electrically Erasable Programmable Read-Only Memory) data; when the outdoor EEPROM data is verified to be correct, sending an updating request instruction to an outdoor unit of the air conditioner; when an updating response instruction returned by the outdoor unit is received, sending the outdoor EEPROM data to the outdoor unit according to a preset communication rate, and after the outdoor unit receives the outdoor EEPROM data, updating the data in the outdoor EEPROM according to the outdoor EEPROM data, and verifying the outdoor EEPROM data so as to return a corresponding verification result to the indoor unit. By the adoptionof the technical scheme, data in the outdoor EEPROM can be remotely updated, updating operation is easy, and safety is high.
Description
technical field [0001] The invention relates to the technical field of air conditioner data update, in particular to a data update method, device and computer-readable storage medium in an outdoor EEPROM of an air conditioner. Background technique [0002] The outdoor control board of the air conditioner generally has a data storage chip EEPROM, which stores various data about the operation of the air conditioner, such as the maximum operating frequency, minimum operating frequency, protection parameters and motor parameters of the compressor. [0003] After the air conditioner is installed, sometimes it is necessary to change the data in the outdoor EEPROM chip of the air conditioner due to various factors such as product upgrades, quality improvement, and special customization. The distance from the ground is relatively high, and it is difficult to directly open the electrical box of the outdoor unit to change the data in the outdoor EEPROM, and there are high potential sa...
