Problems solved by technology

[0003] However, the existing methods for updating the parameters of the inverter air conditioner indoor unit and the EEPROM of the outdoor unit require engineers to disassemble the casing and use a dedicated EEPROM programmer to update the parameters.
[0004] This operation method has a large workload and low efficiency, especially when the air conditioner is used for capacity testing, it is very easy to destroy the experimental conditions, which takes a long time and brings great changes to a series of experiments such as air conditioning system debugging and capacity testing.
At the same time, it is not conducive to the work of the system engineer, and the system engineer will waste a lot of time on parameter update

Embodiment Construction

[0016] Generally, the control circuit of the outdoor unit has a monitoring interface. The monitoring interface of the outdoor unit is connected with the MCU of the outdoor unit for real-time understanding of the operating status and parameters of the air conditioning system. The monitoring interface may be a wired communication interface or a wireless communication module. The wired communication interface is arranged on the electric control board of the outdoor unit to facilitate connection to the upper computer, which communicates with the MCU of the outdoor unit through the monitoring interface.

[0017] Wired communication is mainly used in the development and testing phase to facilitate debugging.

[0018] The method for updating EEPROM data of the inverter air conditioner in the embodiment of the present invention is as follows figure 1 As shown, the air-conditioning electronic control MCU can also write EEPROM chips. Using this feature, the host computer sends the EEPROM dat...

Abstract

The invention discloses a method for a variable frequency air conditioner to update EEPROM data. An outdoor unit control circuit comprises a monitoring interface. A monitoring interface of an outdoor unit is connected with an MCU of the outdoor unit. An upper computer is in two-way communication with the MCU of the outdoor unit through the monitoring interface and sends the EEPROM data to be updated of the outdoor unit to the outdoor unit. The MCU of the outdoor unit completes updating of the EEPROM data of the outdoor unit. Simultaneously, the upper computer uses the MCU of the outdoor unit for transfer and sends EEPROM data to be updated of an indoor unit to the indoor unit, and an MCU of the outdoor unit completes updating of the EEPROM data of the indoor unit. When the method is used for function adjusting and updating of a variable frequency air conditioner, an outer shell of the air conditioner does not need to be dismounted, professional equipment is not needed, operation is convenient, the efficiency is high, and lots of time of engineers is saved.

Description

[Technical Field] [0001] The invention relates to a frequency conversion air conditioner, in particular to a method for updating EEPROM data of the frequency conversion air conditioner. [Background technique] [0002] At present, most inverter air conditioners have EEPROM chips (common ones such as 24C02, 24C04), which store the operating parameter data of the air conditioner controller. The program of the air conditioner controller can be kept unchanged, and the parameters of the EEPROM can be modified to match different system environments. System engineers search for the optimal EEPROM parameters through various experiments. In this process, EEPROM parameter data will be updated frequently. [0003] However, the existing methods for updating the EEPROM parameters of the indoor unit and outdoor unit of the inverter air conditioner require engineers to disassemble the boot shell and use a dedicated EEPROM burner to update the parameters. [0004] This operation method has a large ...
