Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention clearer, the air conditioner communication fault detection device and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] In one embodiment, such as figure 1As shown, an air conditioner communication failure detection device is provided, which includes: a data detection unit 300 connected to the communication lines of the air conditioner internal unit 100 and the air conditioner external unit 200 for detecting transmission data on the communication lines. If the data detection unit 300 does not detect that there is data transmission on the communication line, it is determined that there is a communication failure in the external unit of the ...

The invention provides an air conditioner communication fault detection device and method. The device comprises a data detection unit which is connected to communication lines of an air conditioner indoor unit and an air conditioner outdoor unit and is used for detecting the transmission data on the communication line. If no data transmission is detected on the communication line, the communication line or lines of the air conditioner indoor unit and the air conditioner outdoor unit is / are determined to have a communication fault. If only the first outdoor unit data transmitted by air conditioner outdoor unit is detected, a receiving part of the air conditioner indoor unit or / and the transmitting part of the air conditioner indoor unit is / are determined to have a communication fault. If the first outdoor unit data transmitted by the air conditioner outdoor unit and the first indoor unit data transmitted by the air conditioner indoor unit are detected and the second outdoor unit transmitted by the air conditioner outdoor unit is detected, a receiving part of the air conditioner outdoor unit is determined to have a communication fault. The device and method can determine the position of the communication fault: the air conditioner indoor unit or the air conditioner outdoor unit; prevents a maintainer from carrying out blind maintenance so as to avoid resource waste; and improves the quality and efficiency of after-sales repair.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to an air conditioner communication fault detection device and method. Background technique [0002] Communication failure is a common failure on inverter air conditioners. Under normal operating conditions, the inverter air conditioner performs data exchange between the air conditioner internal unit and the air conditioner external unit. For example: after the external unit of the air conditioner is powered on, the external unit first sends a data packet with the header information of 45 to the internal unit, and the internal unit replies with a data packet with the header information of 45 to the external unit, and then the external unit sends the header information Send the data packet of 49 to the indoor unit. After receiving the data packet with the header information of 49, the indoor unit replies with a data packet with the header information of 49 to the outdoor unit. At t...
