In order to save energy, it is necessary to install multiple multi-split air-conditioning systems to meet different usage times. However, buildings now require a complete facade. The multi-split air-conditioning outdoor units are generally concentrated on the roof or the middle equipment layer. The connection pipes of the multi-split air-conditioning system need to be connected to the air-conditioning indoor units on each floor through the vertical shaft, resulting in a large number of copper pipes in the pipe shaft and a messy layout. If multiple multi-split air-conditioning systems need to be installed at the same time, it is difficult for staff to distinguish the pipes of the corresponding multi-split air-conditioning systems, and it is easy to connect them incorrectly.

[0042] Combine the following Figure 1 A method for identifying a multi-connected pipe of the present invention is described. The method for identifying a multi-connected pipe specifically comprises the following steps:

[0043] S1. Set unique corresponding identification information for each online pipe;

[0044] S2, transmitting corresponding identification information at one end of the online tube;

[0045] S3, receiving corresponding identification information at the other end of the online pipe;

[0046] S4. At the other end of the online pipe, the corresponding relationship of the online pipe is determined according to the received identification information.

[0047] Specifically, each online pipe is provided with unique corresponding identification information, which means that identification information is provided for each online pipe in a one-to-one correspondence, and the identification information can uniquely correspond to the online pipe, so that the online pipe can be distinguished and identified through the identification information. The identification information should have information that can characterize the online pipe and distinguish it from other online pipes. During the assembly process of each online pipe, the corresponding identification information is transmitted at one end of each online pipe, the identification information is transmitted through the online pipe, and the identification information is received at the other end of each online pipe, and the corresponding relationship of the laid online pipes is determined based on the received identification information, thereby ensuring the correct direction of the laid pipeline.

[0048] It should be understood that the above-mentioned "identification information" can be a single information or information formed by a combination of multiple information, such as: sound wave information of different frequencies, material information of different pipeline materials, surface information of different pipe surfaces, etc. or identification information formed by a combination of multiple information. As long as the information can be easily identified and can be transmitted between the two ends of the online pipe, it is considered to be the "identification information" in the present invention.

[0049] The present invention provides a method for identifying multiple online pipes. Unique corresponding identification information is set for each online pipe, the identification information is transmitted at one end of the online pipe, the identification information is received at the other end of the online pipe, and the corresponding relationship of the online pipes is determined according to the received identification information. The present invention provides a method for identifying multiple online pipes. Unique corresponding identification information is set for each online pipe, the identification information is transmitted at one end of the online pipe, the identification information is received at the other end of the online pipe, and the corresponding relationship of the online pipes to be connected is determined in the multiple online pipes, thereby ensuring the correct direction of the laid pipelines, improving work efficiency, and reducing installation costs.

[0050] In one embodiment of the present invention, the step of setting unique corresponding identification information for each online tube, i.e., step S1, specifically includes: setting unique corresponding sound wave information for each online tube. The step of transmitting corresponding identification information at one end of the online tube, i.e., step S2, specifically includes: transmitting corresponding sound wave information at one end of the online tube. The step of receiving corresponding identification information at the other end of the online tube, i.e., step S3, specifically includes: receiving corresponding sound wave information at the other end of the online tube. At the other end of the online tube, the step of determining the corresponding relationship of the online tube according to the received identification information, i.e., step S4, specifically includes: at the other end of the online tube, determining the corresponding relationship of the online tube according to the received sound wave information. In this embodiment, the sound wave information is used as the identification information of the online tube, the sound wave information is transmitted through the online tube, and it is ensured that the set sound wave information is uniquely corresponding to the online tube, so that the corresponding relationship of the online tube is determined by the sound wave information. The corresponding relationship of the online tubes is judged by the sound wave information, and the sound wave information has the advantages of being easy to adjust and easy to transmit in the online tubes. The sound wave information can be adjusted accordingly according to different online tubes, and has the advantage of wide applicability.

[0051] In one embodiment of the present invention, the step of setting a unique corresponding sound wave information for each online tube specifically includes: setting sound wave information of different frequencies for each online tube. At the other end of the online tube, the step of determining the corresponding relationship of the online tube according to the received sound wave information specifically includes: at the other end of the online tube, determining the corresponding relationship of the online tube according to the received sound waves of different frequencies. In this embodiment, by setting sound waves of different frequencies for different online tubes, the corresponding relationship is determined at the other end according to the frequency of the received sound waves. For example: the first online tube emits a sound wave of the first frequency through the sound wave emitter, and the second online tube emits a sound wave of the second frequency through the sound wave emitter... At the other end of the online tube, the sound wave is received, and the corresponding relationship of the online tube is determined according to the frequency of the received sound wave, such as: if the sound wave of the first frequency is received, it can be determined that it is the first online tube; if the sound wave of the second frequency is received, it can be determined that it is the second online tube... and so on. In this embodiment, the correspondence of the online tubes is determined by adjusting the frequency of the emitted sound waves. The sound wave frequency is simple to adjust and easy to operate and determine. The sound wave emitter and the sound wave receiver can be placed inside the online tubes, and the sound waves are transmitted through the online tubes themselves, thereby avoiding mutual interference among the online tubes and accurately determining the correspondence of the online tubes.

[0052] In one embodiment of the present invention, before the step of setting unique corresponding identification information for each online tube, the following steps are also included: S0, setting a unique corresponding number for each online tube. In the step of setting unique corresponding identification information for each online tube, that is, step S1 also includes: the number and the identification information are uniquely corresponding. In this embodiment, before setting the identification information for the online tube, each online tube is first numbered, and the identification information is set according to each number. In the embodiment with "identification information" as sound wave information, after each online tube is numbered, each online tube is set with a corresponding gear, and the gear on each online tube is different, and the gear is uniquely corresponding to its number and identification information. According to different gears, sound waves with corresponding frequencies are emitted, so as to facilitate the determination and recording of the corresponding relationship between the online tubes.

[0053] In one embodiment of the present invention, at the other end of the online tube, the step of determining the correspondence of the online tube according to the received identification information, that is, step S4 specifically includes: at the other end of the online tube, determining the number according to the received identification information to determine the correspondence of the online tube. According to the above embodiment, the online tubes are numbered in steps S0 and S1, and in step S4, the number is determined according to the identification information, thereby determining the correspondence of the online tube. In the embodiment in which the "identification information" is the sound wave information, after the sound wave is received at the other end of the online tube, a unique gear is determined according to the sound wave frequency, thereby determining the corresponding number of the online tube, that is, determining the correspondence of the online tube, thereby facilitating the determination and recording of the correspondence of the online tube.
