Embodiment Construction
[0036] The invention provides a general-purpose mainboard for reducing the number of mainboards of an air-conditioner external unit and a programming method thereof. Only one type of general-purpose mainboard can be installed to replace multiple types of mainboards corresponding to different parameters. The general-purpose mainboard The function of the whole machine can be realized by writing the corresponding EEPROM program of the whole machine on it; thereby greatly reducing the number of models of the main board of the air conditioner external unit. In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] Such as figure 1 As shown, the gen...

The invention discloses a universal main board for reducing the number of air conditioner external unit main board types and a programming method of the universal main board. The programming method comprises the steps of writing an EEPROM testing program on an EEPROM chip of the universal main board, and conducting performance test on the universal main board; writing a corresponding overall unit EEPROM program on the EEPROM chip according to the type parameters of an air conditioner; affixing the name identification of the overall unit EEPROM program on the universal main board. Multiple types of main boards corresponding to different parameters can be replaced only through arranging one type of main board, and the overall unit functions can be achieved through writing the corresponding overall unit EEPROM program on the universal main board; accordingly, the number of the air conditioner external unit main board types is decreased greatly.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a general-purpose main board for reducing the number of main boards of an air-conditioner external unit and a programming method thereof. Background technique [0002] At present, air-conditioning products are mainly divided into two types: direct current and frequency conversion, and each type has many classifications, roughly as follows: [0003] ①. There are many models of the whole machine, ranging from 1P to 5P. [0004] ②. The same model has different energy efficiency levels, including first-level energy efficiency, second-level energy efficiency, and third-level energy efficiency. [0005] ③. The same model and the same energy efficiency level may have multiple compressor models. [0006] The controller (i.e. main board) of the air conditioner outdoor unit needs to distinguish between different models, different energy efficiency, and different compressors. Th...
