Device and method for detecting communication quality of indoor unit and outdoor unit of air-conditioning unit

Abstract

The invention discloses a device and a method for detecting communication quality of an indoor unit and an outdoor unit of an air-conditioning unit. The device comprises a signal receiving module, a unit number setting module, a data storing module, a signal processing module and a display module, wherein the signal receiving module is connected to the signal processing module and is used for receiving communication signals of the indoor unit and the outdoor unit, converting communication signals and inputting communication signals to the signal processing module, the unit number setting module is connected to the signal processing module and is used for setting the number of indoor units, the data storing module is connected to the signal processing module and is used for storing data which are from the signal processing module, the signal processing module is used for analyzing the number of indoor units which are in normal communication each time and calculating the error rate, and the display module is connected to the signal processing module and is used for displaying the number of indoor units which are in normal communication and the error rate in real time. By the aid of the device, the communication condition of indoor units can be reflected in real time, the cause that the communication of units is unstable is determined, the communication quality can be reflected in real time, and the problem can be found out and solved timly.

Description

technical field [0001] The present invention relates to the field of air conditioning, and more specifically, to a detection device and a detection method for communication quality of internal and external units of an air conditioning unit. Background technique [0002] With the continuous development of technology, in order to achieve more precise control effect of air conditioning units, the baud rate and content of communication between outdoor unit and indoor unit have been greatly improved. At this time, communication stability is particularly important. Poor communication will lead to abnormal operation of the unit, and in severe cases, system control disorder will occur. [0003] At present, no manufacturer has launched a method and device for detecting homebus internal and external unit communication, but some air conditioner manufacturers have introduced an external unit communication detection device. The control principle is completely different from this inventio...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problem that the communication quality level of the unit in the prior art cannot be reflected in time, and the fault cannot be found in time, the purpose of the present invention is to provide a communication quality detection device and method for the communication quality of the internal and external units of the air conditioning unit, which can reflect the quality of each unit in real time. The communication status of the internal unit facilitates the determination of the cause of communication instability, and can also reflect the communication quality level in real time, so that problems can be found and solved in time
