Problems solved by technology

[0002] An air conditioner is a device that can adjust the temperature. At present, some air conditioners can automatically record information such as fault information, operating environment, and operating parameters. This kind of information can only be interpreted by developers, and after-sales maintenance personnel cannot use this information, so after-sales personnel still use conventional methods for maintenance and cannot get help from recorded information
[0003] In addition, the fault codes of air conditioners are numerous and complex, and after-sales maintenance personnel do not understand the fault codes, which may lead to incorrect or impossible repairs. The technical level of maintenance personnel is limited, and they cannot analyze the environment where the fault occurs and the cause of the fault. After the machine was repaired, it broke down again, resulting in secondary repairs. Hu Comprehensive returned it to the original factory for analysis, resulting in a long repair time and affecting the use of users.

Embodiment 1

[0043] In Embodiment 1, the data interface 101 is connected to the MCU on the control panel of the air conditioner 200, and the data in the memory 202 is obtained through the MCU.

[0044] Specifically, such as image 3 As shown, after the fault diagnosis device 100 is connected to the target air conditioner 200, the power interface 102 can be connected to the VDD power supply of the air conditioner 200, and the power supply module 70 of the fault diagnosis device 100 can supply power to the fault diagnosis device 100 and the VDD of the air conditioner 200, The reading module 20 is connected with the controller 201 on the air conditioner 200, that is, the MCU, through the data interface 101, and sends an instruction to read information to the MCU on the air conditioner 200. The information recorded in the memory 202 such as EEPROM (Electrically Erasable Programmable Read-Only Memory, Electrically Erasable Programmable Read-Only Memory) such as: fault information, usage time, a...

Embodiment 2

[0046] Embodiment 2 directly communicates with the memory 202 of the air conditioner 200 through the data interface 101 .

[0047] Specifically, such as Figure 5 As shown, after the fault diagnosis device 100 is connected to the target air conditioner 200, the power interface 102 can be connected to the VDD power supply of the air conditioner 200, and the power supply module 70 of the fault diagnosis device 100 can supply power to the fault diagnosis device 100 and the VDD of the air conditioner 100 The reading module 20 is connected with the memory 202 of the air conditioner 200 such as EEPROM through the data interface 101, and automatically reads the fault information recorded in the memory 202 on the air conditioner 200, use time, ambient temperature, coil temperature, exhaust temperature, Compressor running time, current, voltage and other information are transmitted to the control module 40 of the fault diagnosis device 100. Based on these information, the control modul...

Embodiment 3

[0049] In Embodiment 3, the data interface 101 is connected to the MCU on the control panel of the air conditioner 200, and the data in the memory 202 is obtained through the MCU.

[0050] Specifically, in this embodiment, the data information of the air conditioner 200 is stored in the storage unit of the controller 201 . Such as Figure 7 As shown, after the fault diagnosis device 100 is connected to the target air conditioner 200, the power interface 102 can be connected to the VDD power supply of the air conditioner 200, and the power supply module 70 of the fault diagnosis device 100 can supply power to the fault diagnosis device 100 and the VDD of the air conditioner 100, The reading module 20 is connected with the MCU on the air conditioner 200 through an interface, and sends an instruction to read information to the MCU of the air conditioner 200. After the MCU receives the instruction, the controller 201 of the air conditioner 200, that is, the storage unit in the MCU...
